About urban intelligent alarm networking trends

China's economic growth, technological progress, let the people speak of health has improved, but the high-tech crimes to the country and the people of life and property caused great harm, the Government introduced the "harmonious society" slogan, the Ministry of public security also launched the police with technology and 3111 engineering, and a series of safe city construction projects.

The Ministry of public security in order to consolidate social alarm resources, the realization of "police with technology" which is a pilot of the "social security comprehensive management platform" building has also been placed on the agenda. Such very large alarm Management Center combines fixed alarm, move point alarm, video networking, comprehensive alarm monitoring technology, exploration and protection for the future Community law.

Zone alarm as alarm system's core technology has undergone ten years of development, a large number of alarm network, the alert network to stabilize local public security, prevention and suppression of crime is playing an active role in the development process of alarm network has accumulated much experience, but also found some problems.

Alert network is a system that combines a variety of techniques, many different system integrated together, involves the Public Security Bureau, security companies, equipment suppliers, engineering companies, users, and collaborate. Alarm Center is the core of the service, it is set up and manage. Alarm Center operates properly and directly relates to whether timely alarm, timely service and equipment faults promptly corrected. Therefore, in the alarm Center, select a suitable answer alarm the platform is the technological foundation, a sophisticated management mode is functioning. The present city status of alarm systems, we come from the following areas:

1, front-end alarm device.

Current market comparison popular front-end alarm devices usually have the scene warning, alarm, zone alarm and other commonly used function, along with the security equipment development, Crescent Yi, security devices multifunction/compatibility requirements. For example, talkback device has a lot to go into the civilian market, becoming a smart communities essential equipment, if intercom system with alarm function, will be more affected by the general public. With community building grade higher and higher, the user out of the system to set some intelligent Terminal, such as by telephone for remote control of home environment, household appliances control, lighting control, now some domestic foreign intercom, alarm products are beginning to join these features, the family home of control, intercom system, alarm system all together.

2. Alarm Center control section.

Alarm technology is the basis for the construction of the alarm Center, after a long-term platform development, China has formed a ADEMCO685 alarm machine as the core of alarm mode and C & K Monitor II 3.0 + Modem as the core of two mainstream alarm mode, the alarm mode Guide by industry, to alert network provides forceful support. Now traditional alarm system networking usually there are several modes: A-networking, bus, domestic community very intensive, General domestic mainstream products adopt bus system connected to a network, it is now more popular fieldbus 485 bus system, it has a low cost, network speed, and other characteristics, the use is more prevalent in the country. B, phone line networking, basic phone abroad are networking, application is convenient, but because of the slow, easy to plug, and increases the number of telephone costs, domestic use. C, broadband network as technology development, broadband networking beyond the year 2000 to become the new trend. Past our Networking Center requires wiring, construction more difficult, but also increase the cost of the construction of wiring, and the phone line networking cannot avoid telephone line failure, theft or vandalism the disadvantages caused by the phone line. The last two years, for broadband design of TCP/IP protocol become an alarm in the area of new trends, broadband alarm host installation by the user himself can be used with community networking, is very simple, omit the construction of wiring the debugging process.

3, ideal alarm system should possess characteristics.

Alarm centre has a complete alarm mode, you have several patterns and alarm host connection, database integrity, scalability, and ease of management science. Junior intelligent alarm system already has a logical sector indicates that the function can clearly positioning Aviso region and fault zone, for exhibition in a timely manner. While wireless alarm device installation is simple and easy, especially suitable for security system upgrade project. Alarm system as a whole towards specialized, large-scale, network, multifunctional, intelligent, wireless and wired binding direction.
