Application analysis of laser beam of security system in factory perimeter
In recent years, the perimeter defense system has become a basic and indispensable security subsystem of the security system. It has been widely used in residential quarters, factories, schools and other places, and has maintained a very high application growth rate in these fields. As we all know, the current development direction of security technology is to integrate and integrate independent security subsystems such as video surveillance, intrusion alarm, access control, and public broadcasting to form a multifunctional, all-weather, and dynamic comprehensive security management system.
Perimeter alarm development trend
As the first line of defense of the security system, the perimeter alarm plays a very important role. It has evolved from a simple physical barrier in the past to today’s alarm event that triggers related equipment other than the alarm device to perform actions (such as alarm image review, lighting Control, etc.), and with the development of security technology and the maturity of the security market, as well as the further improvement of policies and regulations, digitalization, integration, and networking will be the inevitable trend of its development.
The perimeter alarm system uses technologies such as leaking cables, lasers, and electronic fences to form a visible or invisible "protective wall" at the boundary of the protection. When a wall-crossing behavior occurs, the detector of the corresponding defense zone will send out an alarm signal and send it to the alarm control host of the control center, which will give out an audible and visual warning and display the alarm position. It can also link the perimeter analog electronic screen, and even link the camera monitoring system, access control system, and strong electric lighting system.
With the in-depth application of security systems in all walks of life, the original simple anti-theft alarm system can no longer meet the needs of modern management applications. Based on computer network and software as the core, through information exchange and sharing, combining independent subsystems with complete functions into an organic whole can improve system maintenance level, management automation level, coordinated operation ability, open digital integrated management The platform came into being.
The so-called open digital management platform should be able to thoroughly realize functional integration, network integration, and software interface integration, and can integrate subsystems such as alarm, access control, video surveillance, patrol, fire protection, parking lot, environmental monitoring, and intercom in a unified On the management platform, through the software protocol exchange between the various subsystems, it is efficient and convenient to provide users with an intelligent and stable security integrated management platform.
Application analysis and advantages of laser beam in the perimeter defense system
This article will mainly analyze the perimeter prevention technology of laser beam detectors, which has a good reputation in the market, to get a glimpse of the development trace of perimeter prevention and alarm system technology. Laser beam detector, which not only has the advantages of laser light source, but also has high stability and strong atmospheric appearance. It can adapt to various outdoor harsh and complex application environments. It is a new generation of revolutionary product in the field of anti-theft alarm, which can greatly Expand the application space in the field of anti-theft alarm.
For perimeter prevention and precautions, especially large-scale residential areas, industrial parks, substations and other places mainly use infrared beams. However, judging from the current situation in the country, there are very few long-term applications, and most of them have become a decoration . The main reason is the poor anti-interference ability. It is prone to false alarms due to the influence of the natural environment, including various light interference, strong magnetic interference and bad weather. Therefore, the application of active infrared detection products in our country is still limited. The main reason is the problem of the product itself, which is restricted by the characteristics of the infrared light source.
The use of laser as a detection light source has many advantages. After years of research and hard work, Guangzhou Ailifu Electronics has solved the problems of laser stability, safety and adaptability. The active laser intrusion detector launched by Guangzhou Ailifu Electronics is the field of anti-theft alarm The new generation of revolutionary products can greatly expand the application space of the anti-theft alarm field and bring about new changes in the application concept, mainly including the following aspects:
All-weather application concept-laser energy is concentrated, stronger than infrared light penetrating power, can adapt to rain, fog, frost, snow and dust weather and resist light interference. Whole environment application concept-high stability and special anti-interference design, adapt to various weather and strong magnetic field environment, good environmental adaptability. Full-time application concept-can work 24 hours a day in an outdoor environment. Fully enclosed application concept-high stability characteristics can be closed fortification without gaps in the perimeter prevention of the factory, preventing thieves from outside.
Large-scale application concept--For factory perimeter and larger space, you can choose long-distance laser anti-radiation products. Large perimeter application concept-bus system, network and other transmission methods, an alarm host can control hundreds of laser detectors, greatly extend the transmission distance through optical fiber transmission, and can accurately display the intrusion location.
The disadvantages of infrared beams and infrared gratings are that the infrared light has a large diffusion angle and low power density, and is easily interfered by white light suppression. It needs to be focused to form a detection beam, and special materials are required to filter out stray light. This complicates the entire product structure and causes high energy consumption. In a variety of light source screening, laser has characteristics, high power density and straight line propagation, is an ideal light source.
The active laser beam detector launched by Guangzhou Alif Electronics has undergone a large number of engineering practices and proved that this new product has comprehensive advantages in stability, reliability, anti-interference ability, etc. corresponding to infrared beams and fences. It can fully replace infrared radio products, and enter the perimeter of residential areas, industrial parks, substations and other places to alarm and prevent.
