How to write the work report of Yingtong electric wire

Summary report of integrated wiring project

I. Engineering application

The general steps of integrated wiring project are: investigation-scheme design-civil construction-technical installation-information point test-file arrangement-maintenance.

(1) investigation: the main task is to inquire about the network requirements of customers, conduct on-site investigation of buildings, settle the number of wires, the number of information sockets and the positioning and quantity of cabinets according to the building plan and other materials, and make a comprehensive wiring investigation report;

(2) Wiring scheme design: make wiring material budget table and engineering schedule table according to preliminary survey data;

(3) Civil construction: coordinate the construction team to discuss the responsibilities with the owner, and put forward the wiring permission, which mainly includes drilling, wiring, information socket positioning, cabinet positioning and wiring identification;

(4) Technical installation: mainly the internal installation of information module, distribution frame and cabinet;

(5) Information point test: generally, 12 point tester is used, which can be carried out by a single person, with high efficiency, and is mainly used to test the on-off situation. In depth test, American Flock DSP- 100 cable tester is usually used to check line spectrum, length and attenuation according to TSB-67 standard.

(6) Document management: Finally, the completion report (actual material consumption table, inspection report, floor (building group) wiring table) should be provided to customers to provide data basis for future maintenance;

(7) Maintenance: When the line fails, respond quickly.

Second, technology.

1, in the process of PVC pipe groove construction, lines must be drawn first. If lines are not drawn in advance, direct construction will easily lead to uneven or vertical PVC routing. Although the preliminary work takes more time, it is convenient for PVC to nail in the future.

2. When the outdoor hole is connected to the indoor wall hole, pay attention to the accurate position first, and then drill holes from both sides respectively. First use a small drill to locate, then use a medium drill to get through, and then use a large drill to increase the aperture to avoid cracking the wall.

3. Pull the cable. This link is very important, if the decision or measurement is wrong, it will cause irreparable losses. Therefore, in order to ensure the accuracy of line measurement, we start from the farthest room and adopt the method of measuring the vertical length from the machine room to the metal trunking+horizontal wiring (the length from the shaft to the door of the house)+the length of each information point in the room (the distance between the six information points is different)+30CM coil wire reserved. Because the layout of the room is still different, it is necessary to measure and cut according to the odd and even numbers of the room. This kind of cable pulls one room at a time, and the next room only needs to subtract the distance between two rooms, which is fast, and ensures that each information module has 30CM wires and does not cause waste.

4. When stamping the information module, it is very important to pay attention to one point: for special reasons, when stamping the module, the outer skin is about 1CM away from the module. Because this module is relatively long, if you don't do it according to the above, the installed module dustproof board will be difficult to move and lose its elasticity, so it is necessary to ensure the reasonable installation of the module.

Third, experience

1, specifying requirements and methods.

The person in charge of construction and technical personnel should be familiar with the network construction requirements, construction methods and materials use, and can explain the network construction requirements, construction methods and materials use to the construction personnel. Moreover, we should always direct the construction at the construction site, check the quality and solve the problems raised by the construction personnel at any time.

2, grasp the environmental information

Try to master the environmental data of the network construction site, and put forward protection measures according to the environmental data to ensure the reliability of the network:

In order to prevent accidental damage, outdoor cables should generally be inserted into buried pipelines. If overhead is needed, it should be erected (more than 4 meters) and must be fixed on the wall or telephone pole. Don't erect them on poles, wires, walls or even doorframes and window frames. Indoor cables should generally be laid in the cable trough at the top of the wall.

Communication equipment and all kinds of cables should be fixed to prevent random movement, which will affect the reliability of the system.

In order to protect the indoor environment, cable trays should be installed indoors, and cables should be placed in the cable trays. Cable holes should be drilled for all cables entering the room and passing through the floor, and all cables should be laid horizontally and vertically.

3. Distinguish different media.

Ensure the performance of media, and put forward different construction requirements according to the characteristics of media materials. There are many kinds of communication media in the computer network system, and the construction requirements of different communication media are different, as follows:

optical cable

B when the optical cable is bent, its bending radius should be greater than 30cm.

C the exposed part of optical fiber shall be protected by steel pipe, which shall be firmly fixed on the wall;

D when the optical fiber passes through the underground pipeline, PVC pipes should be added;

E. indoor wiring of optical cable shall be installed in the wire slot;

F optical fiber laying should have expansion allowance, and the allowance should be appropriate, not too tight or too loose.

Coaxial thick cable

A thick cable should not be wriggled, but should be laid naturally and straight;

F. Don't use too much force when laying thick cable guy rope to prevent winding;

G. The thick cable of each network segment should be less than 500m, and several thick cables can be connected with thick cable connectors, but the total length should not exceed 500m and there should not be too many connectors;

H terminators must be installed at both ends of the thick cable of each network segment, and one of them must be grounded;

A, coaxial thick cable can be installed outdoors, but protective measures should be taken, buried in the ground and along the wall part should add steel pipe, in case of accidental damage.

Coaxial thin cable

A. thin cable laying should not be kinked;

B the bending radius of thin cable should be greater than 20cm.

C the distance between workstations installed on thin cables should be greater than 0.5m

D thin cable joints shall be installed firmly to prevent signal short circuit;

E. Thin cables shall be routed in cable troughs to prevent cable damage;

F. When laying thin cables, don't pull hard to prevent them from breaking;

G. A section of thin cable should be less than 183m, and two sections of thin cable within 183m can generally be extended by connecting with a "T" connector;

H terminal devices must be installed at both ends, and at least one terminal device in each section is grounded;

A coaxial thin cable should not be installed outdoors, and the part installed outdoors should be jacketed.

Unshielded Twisted Pair

A. Wiring of twisted-pair cables in corridors and rooms shall be in cable troughs and straight;

B the longest twisted pair from the workstation to the hub is 100 m, and it can be extended by twisted pair connector if it exceeds 100 m;

C twisted-pair cables shall be bundled into cables in the computer room, and the cables shall have certain rules and shall not be misplaced;

D numbers should be marked on both ends of twisted pair to understand the corresponding relationship between nodes and hub interfaces;

F. When the node is not in use, the twisted pair does not need to be unplugged, which will not affect the work of other nodes;

G. In general, twisted pair should not be installed outdoors. When a few are installed outdoors, sleeves should be installed in the outdoor part;

H. select eight-core twisted pair. When installing the connector yourself, all eight wires should be installed. Don't just pack four threads, cut all the other four threads.

4, network equipment installation

Installation of wheel hub

A.a. The wheel hub shall be installed in a dry and clean room;

B.b. The wheel hub shall be installed on the fixed bracket;

C. Generally, the bracket for fixing the hub should be above 500mm from the ground;

D the cable inserted into the hub should be fixed on the bracket or wall to prevent it from falling off accidentally.

Installation of transceiver

A. Select the position where the transceiver is installed on the thick cable (the transceiver is installed on the thick cable, and the shortest distance between two transceivers should be 25m);

B. Install a special tool with transceiver to drill a hole in the thick cable, which should be drilled in the middle of the thick cable and to the bottom (that is, all drill bits are drilled);

C, installing a transceiver connector, wherein the transceiver connector has three pins (a signal pin in the middle and a grounding pin at both sides of the signal pin), and the signal pin is vertically connected into a hole on the thick cable, and fixing bolts are installed and fastened;

D use a multimeter to measure the resistance between the signal pin and the grounding pin, and the resistance value is about 25 ohms (the thick cable terminators at both ends of the thick cable have been installed). If the resistance is infinite, it is generally because the signal pin is not in contact with the thick cable core, or the receiving connector is not firmly fixed, or it is not drilled to the bottom when drilling, so it is necessary to re-drill or re-fix the receiving connector;

E. install the transceiver and fix the screws;

F the transceiver shall be fixed on the wall or bracket, and shall not be suspended in the air;

G. install the transceiver cable;

H the transceiver cable runs parallel to the thick cable, and then turns to ensure the reliable connection between the transceiver cable plug and the transceiver.

Network card installation

A don't choose the slot on the edge of the computer when installing the network card. The organic frame of the slot at the edge affects the plugging and unplugging of the network cable, which brings inconvenience to debugging;

B. The network card installation is the same as other computer cards. Because the network card has external wiring, the network card must be fixed on the computer rack with screws.

5, equipment installation

In order to ensure the quality of network installation, the installation of network equipment should follow the following steps:
