Description

[0002] According to the power safety work regulations, power plants need to install plastic fences and hang safety warning fences before conducting electrical test operations to prevent operators from accidentally entering the live interval. At present, electrical test fences mostly use belts or fences. Belts or fences are prone to collapse during the test, which may cause outsiders to accidentally enter the test area.

When outsiders mistakenly enter the test area, the power cannot be intelligently cut off, which seriously affects personal safety. Therefore, it is urgent to propose a new fence alarm device for power plants. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example

[0032] like Figures 1 to 3 As shown, the present application provides a power plant fence alarm device, including: a fence alarm detection unit 1, a fence alarm communication unit 2, a fence alarm power supply control unit 3 and an audible and visual alarm unit 4.

[0033] The fence alarm detection unit 1 includes: an infrared microwave detection subunit 9 and an infrared grating detection subunit 10. The infrared microwave detection subunit 9 and the infrared grating detection subunit 10 are arranged around the target test area of ​​the power plant, and can be arranged specifically according to the obstacle conditions and shapes of the target test area.

[0034] An infrared microwave detection subunit 9 is composed of an umbrella-type fixing bracket 5, a microwave detector 6 and a power supply communication control module 8. Figure 2 As shown, the microwave detector 6 can be arranged at the top of the umbrella-type fixed bracket 5, and the power communication control module 8 is arranged at the lower end of the umbrella-type fixed bracket 5. The microwave detector 6 is connected to the power communication control module 8, which provides power to the microwave detector 6 and converts the microwave signal detected by the microwave detector 6 into an electrical signal for subsequent transmission. The maximum detection distance of the microwave detector 6 can be 12m, and the detection angle can be 120° horizontally. The power communication control module 8 is used to provide power to the infrared microwave detection subunit 9 and send detection information. The number of the infrared microwave detection subunit 9 is at least one.

[0035] An infrared grating detection subunit 10 is composed of an umbrella-type fixing bracket 5, a grating detector 7 and a power communication control module 8. The grating detector 7 is connected to the power communication control module 8, which provides power to the grating detector 7 and converts the infrared light signal detected by the grating detector 7 into an electrical signal for subsequent transmission. It can be understood that at least two infrared grating detection subunits 10 are required to have the detection function. Figure 3 As shown, the grating detector 7 is installed at the upper end of the umbrella-type fixed bracket 5, and the power communication control module 8 is arranged at the lower end of the umbrella-type fixed bracket 5. The grating detector 7 performs detection based on the detection principle of infrared counter-radiation, and the power communication control module 8 is used to provide power to the infrared microwave detection subunit 9 and send detection information. The number of the infrared grating detection subunits 10 is at least two.

[0036] The fence alarm communication unit 2 is connected to the fence alarm detection unit 1. The fence alarm communication unit 2 uses the STM32F407ZGT6 chip as the main control chip, and uses the serial port to connect and communicate with the fence alarm detection unit 1 to receive the detection information sent by the fence alarm detection unit 1.

[0037] The fence alarm communication unit 2 is connected to the sound and light alarm unit 4. After receiving the detection information sent by the fence alarm detection unit 1, the fence alarm communication unit 2 sends an alarm signal to the sound and light alarm unit 4, and the sound and light alarm unit 4 sends out a sound and light alarm.

[0038] The fence alarm communication unit 2 can also be connected to a target client, which can be a mobile phone, a computer or a smart wearable device, which can be determined according to actual conditions.

[0039] The fence alarm power supply control unit 3 is connected to the fence alarm communication unit 2 , the fence alarm power supply control unit 3 is connected to the electrical test equipment in the target test area, and the fence alarm power supply control unit 3 is connected to the sound and light alarm unit 4 .

[0040] The fence alarm power supply control unit 3 is connected to the fence alarm communication unit 2 , and the fence alarm communication unit 2 forwards the detection information received from the fence alarm detection unit 1 to the fence alarm power supply control unit 3 .

[0041] The fence alarm power supply control unit 3 is connected to the electrical test equipment in the target test area. Specifically, the fence alarm power supply control unit 3 is connected between the mains power supply and the electrical test equipment. The fence alarm power supply control unit 3 is used to turn off the power supply of the electrical test equipment.

[0042] Furthermore, when the target test area is rectangular, the infrared grating detection subunit 10 is arranged at each vertex of the target test area. Figure 4 , the area shape of the target test area M is a rectangle, and the infrared grating detection subunits 10 are respectively arranged at the vertices A, B, C and D of the target test area (only one infrared grating detection subunit 10 is shown in the figure). The infrared microwave detection subunit 9 is arranged between the lines connecting the two infrared grating detection subunits 10. Preferably, the infrared microwave detection subunit 9 can be arranged in the middle of the lines connecting the two infrared grating detection subunits 10. It can be understood that arranging the infrared microwave detection subunit 9 in the middle of the lines connecting the two infrared grating detection subunits 10 can balance the utilization rate and detection area of ​​the area. When the area shape of the target test area is a rectangle and there is no wall 11 around it, the number of infrared microwave detection subunits 9 can be 4.

[0043] like Figure 5 As shown (the up, down, left, and right in the following description are all for Figure 5 For example, when there is a wall 11 on the upper and lower sides (or left and right sides) of the target test area M, the number of infrared microwave detection subunits 9 can be 2, and the number of infrared grating detection subunits 10 can be 4.

[0044] The complete workflow is described below:

[0045] by Figure 4For example, the target test area is in the shape of a rectangle M, the number of infrared microwave detection subunits 9 is 4, the number of infrared grating detection subunits 10 is 4, and the infrared grating detection subunits 10 are arranged at the vertices A, B, C and D of the target test area. Figure 4 Only one infrared microwave detection subunit 9 is shown in the figure, which is arranged in the middle of the line connecting the two infrared grating detection subunits 10.

[0046] The detection area formed by the infrared microwave detection subunits 9 is area F, and there are four areas F. Four detection lines G, H, I and J are formed by four infrared grating detection subunits 10 .

[0047] When an outsider enters any area F, the fence alarm detection unit 1 sends detection information to the fence alarm communication unit 2, and the fence alarm communication unit 2 receives the detection information and sends the detection information to the fence alarm power control unit 3, the sound and light alarm unit 4 and the target client. The sound and light alarm unit 4 sends out a sound and light alarm signal.

[0048] When an outsider enters any area F and touches any of the detection lines G, H, I or J, the fence alarm detection unit 1 sends detection information to the fence alarm communication unit 2, the fence alarm communication unit 2 receives the detection information and sends the detection information to the fence alarm power control unit 3, the sound and light alarm unit 4 and the target client, the sound and light alarm unit 4 sends out a sound and light alarm signal, and the fence alarm power control unit 3 turns off the power of the electrical test equipment.
