Management scheme of residential parking lot

Parking lot management scheme in residential area (1)

With the requirements of community management in the new era, wireless cities and safe communities have gradually become the urgent voice of the residents of the times. The combination of intelligent parking system and other series of security equipment provides an effective way to build a wireless city and a safe community. Through scientific management methods, intelligent community management has become the mainstream.

The following is the realization scheme of community parking system.

A, the engineering construction requirements for main materials and tools

1, entrance controller, automatic door and other packages should be intact, appearance materials should not be damaged, and accessories, spare parts and tools should be complete;

2, engineering building wiring standards, wire specifications and models, should comply with the parking lot engineering design requirements and the relevant provisions of the standard parking lot;

3. Bring complete relevant documents and materials.

Second, the engineering construction wiring technology requires that the parking lot system wiring should not only be safe and reliable, but also be reasonable, neat and firmly installed. The cable installation in the building should be horizontal or vertical, and should be protected by casing to make the cable fixation safe and beautiful; 220V high voltage and signal lines should be laid separately, and should not be worn in the same tube, with a spacing greater than 50CM.

Moreover, all wiring must be sheathed, and PVC pipes and galvanized pipes can be used to avoid the failure caused by rats biting off the lines.

If there is a breakpoint in the middle of the line, it needs to be welded and insulated with a soldering iron; When wiring, the cable must be marked for installation, debugging and maintenance in the future.

The entrance and exit gates and access controllers of power lines need 220V power supply and adopt three-core shielded wires (RVVP3* 1.5). In general, the power supply is connected to a dedicated UPS line. In some cases, AC220V power supply can also be connected nearby, but it should comply with relevant specifications. It is necessary to ensure that the grounding wire of AC220V socket in the system is truly grounded.

Network line

Parking lot networking methods can be divided into: 485 communication, TCP/IP communication, RS422 communication, etc. 485 networking lines must use shielded twisted pair RVVSP2 * 0.5,485 bus length, which can theoretically reach 1200m, and it is recommended not to exceed 1000m.

If so, please choose 485HUB or repeater to improve the communication environment. In order to ensure the stability of communication, a resistor is connected at the end of the communication line, or all shielding layers are connected, and the end can be suspended or grounded according to the situation. 485 network must be bus structure, and star structure is not allowed in whole or in part. More than five kinds of unshielded twisted pairs can be selected for TCP/IP networking lines, and the distance from the controller to the switch or hub should be less than 100 meters.

Equipment requirements:

Long-distance card reader signal line (card reader-controller): The card reader signal line adopts four-core shielded wire (RVVP 4 * 0.5);

Button wire (management room button door): the button wire adopts four-core shielded wire (RVVP 4 * 0.5);

Intercom line (intercom host-intercom extension): The intercom line adopts double-core shielded wire (RVVP2*0.5), which is far away from strong electricity and electromagnetic interference environment;

Signal line of display screen (display screen-controller): The signal line adopts double-core shielded wire: RVVP2*0.5. In order to prevent the signal line from being disturbed, it should be laid separately from the power line;

Gate-controller: the standard parking lot control line adopts four-core shielded wire (RVVP4*0.5), and the simple parking lot (MAC board) adopts two-core shielded wire (RVVP2*0.5), depending on the parking lot type;

Video line (camera-control room computer): The video line adopts SYV75-5 video line, which should not be together with other high-voltage systems, and the distance should be 500mm.

Three, the technical requirements of engineering construction pipe (groove)

There are two kinds of conduit (trunking) wiring: open wire and dark wire. Open wires and trunking should be horizontal and vertical, neat and beautiful. The concealed pipe requires short pipeline, unobstructed pipeline and few elbows. The conduit (trunking) and the conduit (trunking) shall be fixed at a bend or a straight line distance greater than1.5m. ..

In the vertical nozzle that does not enter the box (box), the nozzle should be sealed after threading. During access control wiring, the pipe diameter utilization rate of straight pipes should be 50%~60%, and that of bent pipes should be 40%~50%. In the process of construction, if there are special circumstances that need to be adjusted and modified, the construction can only be carried out after the approval of the company leaders and customers.

When building wire ducts (trunking), it is sometimes necessary to slot: slotting should be based on the following principles:

(1) the shortest route principle;

(2) It does not destroy the original high-pressure principle;

③ Don't destroy the waterproof principle;

④ determine the slot width: determine the number of PVC pipes according to the number of signal lines, and then determine the slot width;

⑤ Determine the grooving depth: If 16mm PVC pipe is selected, the grooving depth is 20-25mm；; If 20mm PVC pipe is selected, the grooving depth is 25-30 mm;

⑥ Appearance requirements of trunking: horizontal and vertical, with the same size;

⑦ Measurement of trunking: The trunking of cassette and distribution box shall be calculated separately. All trunking shall be measured from the beginning to the end of trunking. If the width of trunking exceeds 80mm, it shall be calculated according to the length of double trunking.

⑧ Groove sealing: The wall and ground after groove sealing shall not be higher than the plane, but shall be flush with the original plane.

Four. Technical requirements for equipment installation

1, entrance controller, automatic door

The distance between the control machine and the corresponding gate shall not be less than three meters (the entrance and exit are the same);

The equipment shall be vertical to the horizontal ground, and the inclination angle shall not be greater than1;

3. Brake control button

The gate control button should be installed in a place convenient for personnel to operate, and the specific situation should be operated according to the site.

Verb (abbreviation of verb) technical requirements for grounding circuit

1, coil material: standard φφ0.75mm high temperature tinned wire;

2. There should be no large amount of metal within 50 cm around, such as manhole covers and rainwater ditch cover plate;

3. There should be no power supply lines exceeding 220V within the surrounding 1 m;

4. When making multiple coils, the coil spacing should be greater than 2m, otherwise it will interfere with each other;

5. The standard road is 3m wide, and the ground loop is 2m long, 1 m wide, with a cutting angle of 45 degrees and a length of 20cm;

6. The distance between the coil and the road surface is about 50 cm, and the coils are vertically stacked for 3-8 turns, with a total length of 30-40m；;

7. Cutting parameters of buried trunking: the width is 3-5mm, the depth is 40-50mm, and the depth and width should be uniform and avoided as far as possible.

8, the coil should be in the same balance position with the brake or control machine;

9. The two wires from the coil should be twisted with a density of not less than 50 knots per meter. Untwisted output leads will cause interference. The length of the output conductor should generally not exceed 5 meters. Because the sensitivity of detection coil decreases with the increase of lead length, the length of lead cable should be as short as possible.

Six, the safety island technical requirements

The safety island mainly plays the role of placing equipment and preventing vehicles from hitting the equipment. If the equipment is installed on the roadside due to the limitation of road width, the equipment installation foundation should be made on the roadside. Matters needing attention in the construction of safety island:

1. When installing the equipment, the foundation size should be larger than the actual size of the equipment 10 cm or more to prevent the foundation from being broken by expansion screws when fixing the equipment;

2. The safety island should be about 10 cm- 15 cm from the ground;

3. If the ground on which the equipment is installed is a cement foundation, the foundation can be laid directly on the ground, but the laid place should be paved with a steel bar (φ 20 or more) in a star shape every 25 cm, and the steel bar should be buried not less than 5 cm and exposed not less than 5 cm;

4. If the ground where the equipment is installed is an asphalt foundation, the foundation can be laid directly on the ground, but the laid place should be paved with a steel bar (φ 20 or more) in a star shape every 25 cm, and the steel bar should be buried not less than 20 cm and exposed not less than 5 cm.

Seven, system inspection and testing

Pre-installation inspection: Before installing the equipment, it is necessary to check the installation contract for the variety and quantity of the equipment in advance, and then send the equipment out of the warehouse after it is confirmed. When the equipment leaves the warehouse, it is necessary to test all the equipment one by one to check whether the equipment is normal or not, so as to avoid trouble during installation.

Management Scheme of Parking Lot in Residential Area (2)

With the arrival of winter, in bad weather, the facilities and equipment in the community will be damaged to varying degrees, which will adversely affect the lives of residents. In order to ensure safety and nip in the bud, the property management company should arrange and prevent early, formulate emergency plans in advance, and do a good job of "three defenses" (anti-freezing, anti-leakage and anti-slip) in winter to ensure the normal life and safe travel of residents in the community.

First, antifreeze

With the arrival of winter, the first thing that property management service enterprises should do is to prevent freezing. Generally speaking, we should pay attention to three aspects: vacant houses, facilities and equipment, and corridor insulation.

1. Freeze vacant houses

(1) The property management service enterprise is responsible for freezing prevention of vacant houses. Some developers, out of trust in property management service enterprises, reduce the trouble of looking at houses, and hand over unsold or sold houses (especially commercial outlets) to property management service enterprises for care. For this kind of houses, the following measures should be taken to avoid water leakage and water leakage from the upper and lower pipes due to freezing.

Anti-freezing measures:

① Strengthen indoor cold protection and heat preservation. Check the external doors and windows of vacant houses (including balcony doors and windows), repair the missing glass, and ensure that the doors and windows are closed tightly. When necessary, the sewer pipes should also be insulated with thermal insulation materials such as rock wool, and the doors and windows that are not tightly closed should be sealed with straw mats and cotton curtains. Vacant commercial outlets have no heating, and the main water supply and drainage lines of the whole building are indoors. Once freezing damage happens, it will affect the residents (users) of the whole building. Over the years, such accidents have been common. Therefore, property management service enterprises can't ignore the warm and cold insulation, and don't be reluctant to invest in warm and cold insulation.

(2) Establish a vacancy inspection system. Designated personnel should inspect vacant houses. Generally, it is required to patrol once every three days and once a week at the longest. In severe cold, inspect key houses (such as vacant commercial outlets with facilities) once a day, and report and solve problems in time when found.

③ Establish an emergency mechanism. Make a feasible emergency plan, set up an emergency maintenance team, and prepare emergency supplies before winter. No matter at night or on holidays, relevant personnel can arrive at the scene in time to solve the problem as soon as possible after receiving the emergency report. Really take your time in an emergency, handle it properly, repair it in time, and avoid losses.

(2) Freeze vacant houses of developers. Due to sales or other reasons, developers are responsible for taking care of vacant houses that have not been occupied. Developers are concerned about whether vacant houses and facilities are lost, while property management service companies are concerned about whether these vacant houses harm the rights and interests of others. Therefore, property management service enterprises should communicate and negotiate with developers before winter to determine the winter care and inspection methods of these vacant houses and the treatment plan for emergencies. Clear the person in charge and contact information of the two sides to deal with the emergency of vacant houses, and establish a contact system between the two sides for daily care and inspection of vacant houses. It is necessary to ensure that the situation of vacant houses is clear, the emergency plans of both parties are clear, mutual communication is timely, and emergency treatment is implemented quickly.

(3) Freeze the vacant houses of the owners. No matter what grade of residential area, the phenomenon of vacant houses by owners is widespread. Most of the owners of these vacant houses lack understanding of the importance of anti-freezing in winter, neglect to check the vacant houses in time, and are unwilling to inform the residential property management service office or the surrounding owners of their own information, which leads to the inability to contact the vacant house owners in an emergency. Every winter, empty houses send water (heating pipes or frozen pipes, etc.). ) and can't find the owner, which brings great harm to the neighboring owners. For this kind of vacant houses, property management service enterprises should take the initiative to find the owners of vacant houses before winter, communicate and negotiate how to check the vacant houses in winter, and suggest that the owners take insulation measures for the water supply and drainage pipes, determine emergency plans and exchange contact information with each other. At the same time, inform the owner of the responsibility when an emergency causes damage to others. If there are no valuables in the vacant house, the property management service enterprise can also store the owner's door key (which needs special care) in case of emergency.

2, * * * facilities and equipment antifreeze

After entering winter, the facilities and equipment used in residential areas should also take measures to keep warm and prevent freezing. Water supply and drainage pipelines and fire fighting facilities are mostly located in corridors or basements of houses, so it is easy to cause seasonal freezing injury in winter: the freezing of the following water pipelines leads to water blockage, and the freezing of fire temperature alarms leads to water leakage, which happens in many communities. Therefore, property management service enterprises should keep these facilities and equipment warm. The heat preservation method can be perlite block enclosure or rubber pipe, rock wool, brown hemp, etc. When necessary, hot air curtain facilities can also be installed at the entrance of the basement (or underground parking lot). These insulation measures are the benefits of one-time investment for many years.

3, corridor insulation should attract enough attention.

Before winter, the doors and windows of the corridor should be closed tightly, and the defective glass should be repaired in time. Roof entrances and exits should also be tightly closed and locked for protection if necessary. Door bows should be installed on corridor doors without door closers, so that corridor doors can close automatically.

Second, leakage prevention.

* * * In winter, the leakage of parts is mainly in the downspout of roof and external wall.

1, roof leakage prevention

The main parts of roof leakage in winter are under the waterproof eaves of parapet and the drain outlet of centralized drainage. The reasons are: first, the coiled material under the waterproof eaves is not firmly bonded, and there is an inclined gap. When the snow on the roof melts into water beyond the edge of the coiled material, it will leak down along the inclined gap; Second, the drain pipe is welded with iron plate, and the coil is stuck on the iron plate. When it is cold in winter, the expansion coefficients of iron plate and coil are different, which is easy to cause the coil to tilt. The snow on the roof melts into water and leaks along the upturned place. In addition, the narrow drainage outlet makes waterproof construction difficult, and the careless operation of waterproof construction personnel is also one of the reasons for water leakage here in winter.

Main methods to prevent roof leakage in winter;

(1) Before winter, carefully check whether there is any crack in the coiled material under the waterproof eaves of the parapet. If there is any gap, it should be filled with waterproof ointment, which should be firm and dense;

(2) Carefully check whether the drainage iron plate and coil are firmly pasted. If it is found that it is not dense or not in place, it should be baked with a blowtorch or re-pasted with waterproof coiled material immediately;

(3) In case of roof leakage in winter, the snow and accumulated water (ice) on the roof should be quickly removed, and then the ice residue and water droplets at the leakage place should be carefully cleaned, dried with a blowtorch when necessary, and then filled with waterproof ointment.

2. Prevention and treatment of external wall downspout leakage.

Most roofs have organized drainage. In winter, the snow on the roof melts into water, which flows into the outer wall downpipe from the roof drain and is discharged. However, the temperature in the downpipe (especially the downpipe on the north outer wall) is very low and lasts for a long time. When the snow water flows down the downpipe, it freezes on the inner wall of the downpipe, gradually turns into ice layer by layer to block the whole downpipe, and then expands and bursts the downpipe. So that snow water leaks out and flows along the surface of the outer wall, and freezes on the surface of the outer wall when it is cold at night. When it is cold in winter, the phenomenon of ice on the outer wall can be seen everywhere, which is the result.

Main methods to prevent the leakage of downpipe:

(1) During the melting of the snow on the roof, pay attention to clean up and drain the accumulated water in time. When it gets dark, knock the upper part of the downpipe with a wooden stick to break the frozen layer stuck on the inner wall of the downpipe, so as to avoid ice accumulation blocking the whole downpipe;

(2) If ice is found on the external wall, it should be removed in time. It can not only prevent the ice from falling and hurting people, but also reduce or avoid the mildew and long hair on the wall here when it blooms in spring.

Third, anti-skid.

In winter, due to the cold weather, the snow and ice on the road surface are very slippery, which brings great inconvenience to people's travel. If you fall down carelessly, it is easy to hurt yourself and cause safety accidents. Therefore, inform the owner of some tips for anti-skid in winter and remind him in time.

1. Anti-skid for personnel:

(1) Clear the ice and snow on equipment, roads, stairs and passages in time.

② Anti-skid facilities, such as anti-skid blankets and mats, should be set on the main passages.

③ Set up safety warning signs in places where there is danger of slipping.

(4) Up and down stairs should have handrails.

⑤ Wear non-slip shoes when traveling in snowy winter, and walk on the steps.

6. Don't walk too fast in snowy days, with a small stride, and don't put your hands in your pockets, because swinging your upper arms back and forth can play a balancing role.

⑦ If you really accidentally fall down on the road, try not to support the ground with your wrist, because this falling posture is the most likely to cause an arm fracture. Once you fall and break a bone, don't rub it around to avoid aggravating the injury. Fix the fracture site with scarves, boards and other tools, ask others for help or call the police, and send them to the hospital for treatment as soon as possible.

2. Car anti-skid:

(1) Anti-skid chain, put a layer of anti-skid chain on the outer layer of tire, just like putting anti-skid shoe covers on shoes as mentioned above. Relatively speaking, the price is more affordable.

② If the budget permits, you can change snow tires. In order to ensure that your tires maintain good grip and handling performance on winter roads and ensure your driving safety, it is necessary to change into winter tires.

3. Bicycle anti-skid:

Increasing the contact area between the wheel and the ground can prevent skidding and remind the owner to choose thicker tires. Don't carry too many or too heavy items on the car body. During riding, remember not to brake suddenly, or the wheels will slip and lose balance. It's best to ride slowly when traveling in snowy days. Try to avoid sharp turns, and keep the center of gravity perpendicular to the ground through the car axis. The larger the turning radius, the safer it is.
