The target warning area is formed according to the transmission and reception areas of the first infrared signal and the second infrared signal of the infrared transceiver unit of each infrared device.
[0023] The signal analysis device detects the infrared signal intensity of the target warning area and generates a first alarm signal when it detects that the infrared signal intensity of any area in the target warning area is less than a preset intensity.

[0034] When an infrared signal that does not meet the preset signal matching coding conditions is detected, it can be understood that an unauthorized infrared signal emitted by an unauthorized infrared transceiver unit is received by a certain infrared transceiver unit. The second recording unit records the time stamp and coding of the received infrared signal that does not meet the preset signal matching coding conditions and sends them to the second generating unit. The second generating unit generates a second alarm signal according to the time stamp and coding of the infrared signal that does not meet the preset signal matching coding conditions and sends it to the alarm device.
[0035] Optionally, in some embodiments, the infrared early warning alert zone system 10 further comprises a communication device connected to the signal analysis device of each infrared device, for generating first alarm information according to the first alarm signal and / or second alarm information according to the second alarm signal to a remote terminal.

[0051] In order for those skilled in the art to further understand the infrared early warning warning zone system of the embodiments of the present application, the following will be described in detail in conjunction with specific embodiments.
[0052] First, three or more groups of cooperative infrared devices are arranged: each group of devices includes a movable base, a telescopic straight rod, and an embedded infrared sensor. The movable base includes a counterweight box and a pulley assembly with a balance foot, which ensures that the device is stably placed on complex ground; the telescopic straight rod adopts a multi-stage nested structure, with a telescopic range covering 0.5-2.5 meters, suitable for different height scenes; the sensing assembly is designed to be small, distributed on three levels of the straight rod, and the sensors are embedded in the connecting rods, with the emitting end and the receiving end corresponding to each other. A single infrared device can emit cross infrared signals to the other two groups, forming a three-dimensional mesh or wall barrier.
[0053] Among them, the infrared sensors are distributed on three levels of the straight rod, and the emitting end and the receiving end of the infrared sensors correspond to each other, and a single infrared device can emit cross infrared signals to the other two groups, forming a three-dimensional mesh or wall barrier; the moving device 4 has a pulley assembly with a balance foot, which ensures that the device is stably placed on complex ground; the counterweight box ensures the stability of the equipment; the first telescopic straight rod and the second telescopic straight rod adopt a multi-stage nested structure, with a telescopic range covering 0.5-2.5 meters, suitable for different height scenes, and the loudspeaker is used for sound and light alarm work.
[0054] The signal analysis device continuously monitors the integrity of the infrared barrier, and judges whether there is penetration (such as personnel intrusion causing signal interruption on a certain road, and significant reduction of infrared signal strength) through the change of infrared signal strength; the alarm device includes a buzzer, a voice broadcaster, and an LED warning light, which emits high-decibel buzzing and cyclically broadcasts “intrusion into the warning area” when triggered, and flashes at a high frequency, while sending alarm information to the control terminal.
[0055] Based on the above infrared intelligent early warning alert system, the specific operation steps are as follows: 1. Deployment preparation: According to the shape of the alert area (such as rectangle, irregular polygon), four infrared devices are placed at the four corners or key nodes of the area. Adjust the balance leg of the mobile base through the remote control terminal to ensure the vertical stability of the infrared device; set the target height of the telescopic straight rod (such as 2 meters) and the emission angle of the infrared sensor (form cross coverage between adjacent devices), set the alarm volume and signal verification threshold, as shown in the figure. Figure 3 .
[0056] 2. Barrier start and state monitoring: Press the "start work" button of the remote control terminal, the telescopic straight rod of the four infrared devices automatically expands to the preset height, and the embedded infrared sensor starts synchronously. After clicking the "laser emission" button, the infrared signal is emitted, and the four infrared devices form a network or wall-shaped barrier through cross signal, and the control terminal displays "alert area has started" and the barrier integrity diagram, Figure 4 .
[0057] 3. Break-in monitoring and alarm response: When a person or object penetrates the infrared barrier, the infrared signal strength of the corresponding path drops sharply, and the signal analysis module determines the break-in state within 0.5 seconds, triggering the sound and light alarm component to work. The remote control terminal displays the break-in position in real time (such as "infrared device 2 and infrared device 3 middle layer signal interruption"), and records the break-in time and duration, as shown in the figure. Figure 5 .
[0058] 4. End and reset: After the work is finished, press the "stop emission" button, the infrared signal stops emitting, and the sound and light alarm is turned off. Click the "shrink reset" button, the telescopic straight rod automatically retracts to the initial length, and the four infrared devices return to the rectangular box state, the work is finished, as shown in the figure. Figure 6 .
[0059] Take the 110kV transformer electrical test operation alert area of a substation as an example to elaborate the implementation process of the application.
[0060] 1. In the deployment preparation stage, the technician places four groups of infrared devices around the transformer (in an equilateral quadrilateral distribution, with an adjacent device spacing of 8 meters) according to the transformer test safety distance (a circular area with a radius of 5 meters). Adjust the balance leg of the mobile base through the remote control terminal to adapt to the cement hardened ground of the substation site; the target height of the telescopic straight rod is 2.2 meters (higher than the average height of an adult), and the embedded infrared sensor is distributed in three layers (each layer is spaced 55cm apart), considering that there may be objects blocking the signal around, the corresponding level sensors of adjacent infrared devices are set to a 45° cross emission angle to avoid interference.
[0061] 2、Start the barrier system, press the remote control terminal "start work" button, four groups of infrared device telescopic straight rod through motor drive, in 40 seconds within the embedded infrared sensor synchronization to 2.2 meters high, after encoding calibration activation. Click "laser emission" button, synchronization coding module triggers infrared signal emission, each signal carries encrypted code, control terminal touch screen display red ring barrier schematic diagram (labeled "high voltage test area"), and real-time refresh signal strength.
[0062] 3、When the test personnel do not follow the procedures around, from the transformer through the warning area, the upper and middle two groups of cross infrared signal is continuously blocked, the signal strength is reduced, the real-time signal analysis module determines "continuous intrusion". Trigger the audible alarm component, issue high decibel intermittent beep and broadcast "high voltage test area intrusion, immediately evacuate!", The remote control terminal displays a yellow flashing alarm frame (labeled someone intrusion) synchronously, and sends alarm information to the test person in charge.
[0063] 4、After the test, the technician inputs the unlocking password (to prevent misoperation) on the remote control terminal and presses the "stop emission" button. The infrared signal is turned off and the alarm sound is terminated. Click the "shrink reset" button, the telescopic straight rod is retracted to the initial length (70 cm) within 30 seconds, and the four groups of infrared devices are automatically folded into a rectangular box (convenient for carrying in the substation equipment room).
[0064] In summary, the beneficial effects of the embodiments of the application are as follows: 1、Strong adaptability to high voltage scene: for the circular layout of the transformer test area and the strong electromagnetic environment, through the adjustable angle embedded sensor and encryption coding technology, the net-shaped barrier ensures that there is no signal blind area around the high voltage equipment, solving the problem that the traditional warning means is easily disturbed by electromagnetic interference in electrical test.
[0065] 2、Safe and efficient warning: the alarm information highlights the "high voltage danger" feature, combined with audible and visual alarm and mobile terminal push, the response speed is significantly improved compared with manual monitoring, which can issue a warning in an instant when personnel misenter, reducing the risk of electric shock.
[0066] 3、Excellent anti-interference and durability: the sensor adopts embedded design in explosion-proof shell, which reduces the false alarm rate in the dusty and strong electromagnetic environment of the substation; the motor telescoping and corrosion-resistant base design adapt to the complex outdoor conditions of the substation, prolonging the service life.
[0067] 4、High deployment flexibility: no need to rely on fixed support points, mobile base with balance feet can quickly adapt to complex terrain such as cement ground and cable trench edge, significantly improving the deployment efficiency compared with traditional physical isolation means such as pipeline and fence, and the position can be dynamically adjusted according to the test area.
[0068] 5. Full-coverage area protection: A mesh-like infrared barrier formed by the cross-emission of multiple infrared devices achieves three-dimensional "area protection" from the ground to a height of 2.2 meters. This provides a wider coverage area than the traditional "linear warning" of a single infrared ray and eliminates blind spots in monitoring.
[0069] According to the infrared early warning and alert zone system proposed in this application, the infrared transceiver unit of any infrared device sends a first infrared signal to at least one other infrared device and receives a second infrared signal sent by at least one other infrared device. A target alert zone is formed based on the transmission and reception areas of the first and second infrared signals. When the signal analysis device detects that the infrared signal intensity in any area of the target alert zone is less than a preset intensity, a first alarm signal is generated. The alarm device provides acoustic and / or optical alarm reminders based on the first alarm signal. This solves the problems of traditional infrared early warning and alert zone systems, such as poor flexibility, susceptibility to interference, and lack of real-time monitoring capability for the integrity of the alert zone, leading to high rates of missed and false alarms and difficulty in meeting the high-precision alert requirements in complex scenarios. The system offers comprehensive coverage, strong anti-interference capabilities, a concealed structure, and real-time monitoring of the alert zone status.
