Family safety accident

Home automation and security are developing in the direction of high integration and comprehensive digitalization.

In the digital home system, in addition to network video, trendy electronics and audio-visual enjoyment, home automation and security equipment also play an important role. The so-called home automation refers to the use of electronic technology to integrate or control home electronic products or systems (such as lighting, coffee stoves, computer equipment, security systems, heating and cooling systems, audio-visual systems, etc.). ). Its function is mainly realized by receiving information from sensors (which can sense changes in the external environment, such as changes in light caused by sunrise and sunset) through a central management platform, and then controlling other electronic and electrical products with established programs. Besides being able to control household appliances through various interfaces (keyboard, touch screen, keys, computer, telephone, remote controller, etc.). ), the owner of the house can also send control signals to the central processing equipment and receive information from the central processing equipment at the same time.

Home safety equipment has been on the digital train. Modern sensing technology, digital information processing technology, digital communication technology, computer technology, multimedia technology and network technology are the driving factors. The latest security equipment has developed into a highly integrated system, which can collect, process, transmit and display all kinds of security information. A complete security system mainly includes access control, alarm and monitoring, and network monitoring is the main equipment. Global anti-terrorist organizations, coal mine gas explosion and other sudden public safety accidents have put forward higher and higher requirements for network monitoring equipment. In addition, applications such as customer service website and customer behavior analysis are also promoting the development of network monitoring equipment. Driven by these demands, network monitoring equipment has also experienced two stages of development, full analog and partial digital, and is striding into a new stage of comprehensive digital development.

More integrated home automation system

Home automation is an important system of digital home. When digital home first appeared, home automation was even equivalent to digital home. Until today, it is still one of the cores of digital home, but with the wide application of network technology and the maturity of network appliances/information appliances, many product functions of home automation will be integrated into these new products, so that such simple home automation products will be less and less in system design, and its core position will be replaced by sub-home network/home information system, which will play a role as the control network part of home network in smart home. At present, the most famous home automation system is American X- 10.

Home monitoring is an important part of digital home.

"The main goal of home automation technology is to provide a rich lifestyle by connecting home appliances and equipment to the central control system, thus making home life more comfortable, safe and efficient." Leslie Leong, senior manager of stmicroelectronics (ST) Greater China Multi-system Business Department, said. For ST, home automation is undoubtedly a relatively new market. "At present, many devices and protocols are still piled up on the draft table for discussion." Therefore, when answering which home automation products will become the mainstream products in the market, Leong pointed out that "it is futile to discuss which products are the most popular and which products are the most promising in this case."

Obviously, Liang Jiajie has combed out a clearer vein. He believes that the existing motion control system, gas alarm system, remote control system and "temperature control system" and other comfortable living systems will be further integrated in the future. "These systems have different communication buses and different control interfaces," he said. "But in the future, all these subsystems will be integrated by using the same control platform and the same general protocol."

Although it has just entered the home automation market, st still provides a variety of solutions for OEMs to choose from. Such as a power line modem suitable for low bit rate home automation. In addition, as high bit rate wireless technologies, WiFi and Bluetooth are also recommended by ST for home automation networks. "In the next few years, with the launch of the latest ZigBee standard, st will provide the most recognized ZigBee network processor to promote the home automation and building automation market." Liang Jiajie said.

Through a platform built with ARM9 kernel, all devices are integrated (connected by power line, Bluetooth, ZigBee and Internet), and ST provides a complete solution for home automation network. This is similar to a processor that controls multiple media and protocols. If it is missing, it will lead to the inability to' talk' to each other. "Leong said," It can help achieve synchronization between different devices. Most importantly, it expands the concept of' security', such as confidentiality, authenticity and data integrity. "

Compared with the semiconductor manufacturer ST, Honeywell, as a complete machine manufacturer, has always been a technical pioneer in the home automation market. "Compared with other competitors, Honeywell's products have numerous advantages," said Ben Cornett, president and CEO of Honeywell Security Group. "But there are two points to emphasize: first, our products have the most modules and functional integration in the world; Secondly, maybe other competitors will launch similar integrated home automation solutions soon, but by that time, maybe we have launched the next generation of products, and we are always ahead of our competitors. "

Honeywell's highly integrated digital home system connects network appliances, emergency call, access control, lighting control module, fire detector, infrared detector, electronic door lock and touch screen operation terminal, and integrates security system, gas valve control, lighting control, curtain control, scene linkage control and even air conditioning control, information appliance control, visual intercom and remote communication system. With home network system and Ethernet as transmission platforms, data is realized through service system and sub-systems of the community.

"Home automation control system' home gateway' is the core of digital home: air conditioning control, information appliance control, security system, gas valve control, lighting control, curtain control, scene linkage control, visual intercom and remote communication. All of these rely on home network system and Ethernet as platforms for information transmission and data sharing. " Home Gateway is a personalized network home solution system specially designed by Honeywell for real estate owners, which is used to protect the safe and comfortable home environment and inform the home situation. Because of the built-in Linux operating system, the home gateway system maintains high efficiency and economy, and can provide customers with higher value than other home servers. Compared with other home servers, home gateway has many competitive advantages: first, it can connect more terminal devices, and can link up to 8 terminals at the same time; Secondly, it is easier to control and manage; Thirdly, the price of home gateway is more reasonable and the installation size is smaller; Finally, it can also be linked with other home facilities such as lighting control and curtain control to realize linkage control.

Security devices: digital and wireless

As mentioned above, a complete security system mainly includes three parts: entrance guard, alarm and monitoring. Including burglar alarm, CCTV monitoring alarm, entrance guard alarm, security patrol alarm, visitor alarm, integrated garage management, alarm signal transmission system networked with 1 10 alarm center and other subsystems. These subsystems can be independently set up and operated, and monitored by the central control room, or integrated with other integrated systems for centralized monitoring.

In terms of visual intercom of access control system, Honeywell's home gateway system also has digital visual intercom function based on TCP/IP, including front door call, guard call, lobby housekeeper call, household visual intercom and so on. Through this system, property managers can release information or notices to residents, and residents can check them themselves. Intelligent design also fully considers the application of various home network appliances in the future, and adopts advanced home integrated wiring technology to comprehensively arrange and manage home data, voice and control points.

In the past year, two first-time and truly large-scale high-grade intelligent buildings (Shenzhen Mangrove West Bank and Tianjin Seton Center) both adopted Honeywell's technology to realize intelligent residence. Taking the latter as an example, through Honeywell's home gateway system, residents of Tianjin Saiton Center can set three security modes: at home, going out and sleeping (residents can set the state of sector, lighting, curtains and air conditioning in each mode), and reserve webcam lines through electronic door lock cloth (removal) to provide home monitoring for residents. For example, when the electronic door lock is opened, the system will automatically disarm, and at the same time, the lights, curtains and air conditioners will start to be controlled according to the mode set by residents in advance. Every household needs only one button to go out. At this time, all the lights and curtains can be turned off, and the home will immediately enter a state of protection.

Using Honeywell's HS-5000 home intelligent gateway equipment, residents can also use mobile phones, telephones and the Internet to inquire about home security, visitor records, lighting, air conditioning, network home appliance control and so on. In fact, in addition to LAN/WAN, Internet and email, various wireless communication methods such as Wi-Fi, CDMA and PDA are rapidly being applied to security devices.

The wave of comprehensive digitalization has swept the security equipment market, especially the high-end security system. In these systems, through various network types (wired telephone and network, wireless telephone and network, VoIP network, NGN soft switch network), information including transmitting data packets, collecting and analyzing voice, fax, short message, network data, e-mail, chat, internet browsing, etc. can be intercepted and analyzed. In addition, real-time monitoring and recording of data traffic can be realized based on enterprise intranet protection rules, and records of all operations such as sending, copying, modifying and deleting can be queried based on enterprise intranet protection rules; Realize the analysis and tracking of call center records.

Sony recently announced the launch of four new safety monitoring products, targeting the China market and the global market respectively. Among them, SSC-ET 180P integrated zoom camera specially developed for China market is the company's first brand integrated zoom camera, which includes 18 times optical zoom and 12 times digital zoom with high quality zoom lens, and can automatically focus. With the command set of VISCA protocol, all functions of SSC-ET181P/ET180 P can be remotely controlled through RS-485 interface. It can meet the high-quality requirements of high-end users for monitoring.

At the same time, SNC-CS1011economical gun webcam launched for the global market was also released. SNC-CS10/1Camera is upgraded from CCTV to IP monitoring, which is specially designed for high-quality and low-cost network monitoring applications. Using Sony's powerful progressive scanning CCD and DSP technology, high-resolution images can be made. The output video image supports JPEG and MPEG-4 compression formats, which users can choose flexibly. It is reported that although analog monitoring equipment is still the mainstream in the monitoring market, with the development of digital technology, digital monitoring networks have gradually been widely used. Sony's new monitoring mixed IP solution can help users build an IP network environment on the original system.
