The application prospect of the flagship version of intelligent beam identification laser beaming

In the field of burglar alarm, there are many popular perimeter defense technologies, such as vibration cables, outdoor three-detection probes, leaky cables, tension fences, electronic fences, and infrared radiation. The perimeter alarm system uses a technology such as leakage, infrared, electronic fences to form a “protective wall” that is visible or invisible at the boundary of protection. For outdoor prevention, especially for residential areas, industrial parks, and substations with large space. Main places such as infrared radiation/electronic fences are mainly used in other places. However, from the current situation in the country, there are very few real-time applications, and most of them become a kind of display. The reason is mainly due to the poor anti-interference ability, which is susceptible to false alarms due to the influence of the natural environment, including various optical interferences, strong magnetic interference and bad weather. Therefore, the application of active infrared detection products in China is still limited, mainly because of the problem of the product itself, and is subject to the characteristics of the infrared light source.

The laser as a detection light source has many advantages. After years of research efforts, Guangzhou Ai Lifu Electronics successfully solved the problems of laser stability, safety and adaptability. The company's first active laser intrusion detector is new in the field of anti-theft alarm. A generation of revolutionary products, and now the laser beam has been updated to the fifth generation - the flagship version of the laser beam, the performance is more stable and smarter, as follows:

Viandas fifth-generation flagship laser detector performance characteristics and technical parameters

1. Using 980nm completely invisible laser as the detection light source to resist environmental disturbances such as wind, frost, rain, snow, fog, sand, smog, etc., to achieve safe and reliable invisible prevention

2, select 1.8mm thick 304 stainless steel shell, strong resistance to violent damage, outdoor installation can resist the erosion and aging of harsh environment. The Viandas flagship laser detector is the same as the standard version of the laser detector, it is also made of 304 stainless steel casing. It can be used for a long time in indoor and outdoor environments and in various harsh environments.

3. Each beam is independently encrypted and demodulated. The same detector does not form mutual coverage and interference between the beams at any working distance. Each beam can be accurately positioned anywhere between the laser transmitter and the laser receiver. Identify the alarm (patent).

4. Each beam can output two kinds of alarm signals: high and low level and normally open/normally closed switch. It can be connected with control devices such as computer and alarm controller at the same time or separately to meet the system management of various purposes.

5, four trigger alarm time is optional, can be applied to security and various special testing sites

6. The first two modes of debugging and detection can be switched (patented) to achieve fast and precise alignment, and the alignment debugging efficiency is more than doubled.

7. Single/double beam trigger alarm optional (patent), can be applied to various purposes and places

8. Each beam X/Y axis can be adjusted independently, the angle is adjusted by ±30°, and the same pair of detectors can be used for the same difference.

9. Detector height and number of beams can be customized, up to 144 beams, up to 6 meters

Laser working principle

The laser beam detector consists of two parts: the receiving and the transmitting.

The laser transmitter emits a laser line to a receiver installed at a few hundred meters or even a few kilometers away, and its beam has a single beam, a double beam, or even multiple beams. When the corresponding laser beam is interrupted, the receiver signals an alarm. The receiver is composed of an optical lens, a laser phototube amplification and shaping circuit, a power driver, and a laser beam-forming mechanism.

The working principle is that the receiver can receive the laser beam as a normal state, and when the intrusion occurs, the laser beam emitted by the transmitter is blocked, that is, the photocell receives no laser light source, thereby outputting a corresponding alarm electric signal, and After the shaping is amplified, the switch quantity alarm signal is output, and the alarm signal can be received by the alarm controller, and the linkage actuator is activated to start other alarm devices, such as an alarm host, an audible and visual alarm, an analog electronic map, a monitoring system, a lighting system, and the like.

Application characteristics of laser radiation detection system in perimeter security

1. Low false alarm rate The laser radiation detection system has obvious advantages in adapting to harsh weather conditions compared with similar active detection systems. The laser beam has a high power density, a small divergence angle, and a concentrated beam. The directionality is good (the infrared detector emits a large spot area. The spot diameter is more than 3 m at a distance of 100 m, and the spot diameter of the laser is less than 0.2 m at a distance of 100 m). Under the condition of using the same power device, the power density of the laser beam at the target receiving point is several hundred to several thousand times the power density of the infrared light emitting diode beam. Therefore, under the same climatic conditions, the transmission attenuation of the laser radiation system is much smaller than that of other similar detectors. And it has strong ability to penetrate rain and fog, and the detection distance can reach hundreds of meters to several kilometers, which can greatly reduce the false alarm caused by the influence of climate environment.

2. Stable performance The whole is made of stainless steel. The mechanical structure of the system is precise. The laser system and optical components are processed by precision instruments, and the internal structure is stable. The system is installed firmly and reliably. The laser intrusion detector shell is made of stainless steel. It is fixed on the cement foundation. In addition to the protective cover for sand and rain, the base with increased width can reduce the impact of external force. Effectively cut off the impact of strong winds on the structural stability of the system.

3. Strong anti-interference ability The laser anti-radiation system has strong anti-electromagnetic interference capability, and does not have any electromagnetic interference to areas and equipment outside the laser beam propagation path.

4. Commissioning and maintenance is convenient. The laser radiation system is debugged by camera visualization. The position of the light source is clearly visible. The camera visual debugging method can guide the debugging accurately and quickly. The position of the spot is clearly determined during the debugging and maintenance of the laser alarm system, which is convenient for quick debugging. Maintenance work is quick and easy.

It is followed by the security products technology advancing with the times. Continuous innovation, the only way to adapt to market development and demand, I believe that in this networked / intelligent era background, more security companies will introduce more professional / intelligent security equipment, and promote the development of the security industry.
