Embodiment

[0017] The intelligent safety fence that is used for high pressure test of the present embodiment is as figure 1 As shown, it consists of four columns 1; each column 1 is provided with two ultrasonic sensors 2 facing the outside of the fence, the included angle is about 90 degrees, and the emission angle of each ultrasonic sensor 2 is 120 degrees. Fence with full coverage for a week. Each column 1 is also provided with an infrared beam sensor 3; the transmitting end and the receiving end of the infrared beam sensor 3 are respectively located on two adjacent columns 1, and are aligned with each other to form a loop; the receiving end of the infrared beam sensor 3 The end is connected with a wireless signal transmitting circuit, and is connected with the switch 4 of the high-voltage test equipment 5 in the fence through the wireless signal; the output interface of the receiving end of the ultrasonic sensor 2 is connected with an alarm.

[0018] The ultrasonic sensor 2 includes ...

Abstract

The invention relates to an intelligent safety rail arranged at the periphery of a high-voltage test device, and belongs to the technical field of safety protection. The rail is composed of a plurality of stand columns, the stand columns are provided with infrared bijection sensors and ultrasonic wave sensors towards the outer side of the rail, the transmitting ends and the receiving ends of the infrared bijection sensors are located on two adjacent stand columns respectively and are aligned to form loops, the receiving ends are connected with a wireless signal transmitting circuit and connected with a switch of the high-voltage test device in the rail through wireless signals, and output ports at the receiving ends of the ultrasonic wave sensors are connected with an alarm apparatus. By means of the intelligent safety rail used in a high-voltage test, when a worker gets close to a high-voltage test area, an alarming signal can be given out; when the worker breaks through an infrared bijection light path, a low-voltage power source is rapidly cut off through the switch, power supply to the device in the high-voltage test area is stopped, it is guaranteed that the device in the high-voltage test area is changed from the electrification state to the non-electrification state, and electric shock hazards are accordingly eliminated.

Description

technical field [0001] The invention relates to an intelligent safety fence arranged around a high-voltage test device, which belongs to the technical field of safety protection. Background technique [0002] At present, hard (soft) fences with warning signs are usually used as basic safety protection measures in high-voltage tests, and full-time guardians are set up to remind testers to operate correctly and warn irrelevant personnel not to enter the high-voltage test area. However, in the case of the guardian's inattention or weak guardianship, it is still easy for irrelevant personnel to stray into the high-voltage test area and accidentally touch the live high-voltage equipment, resulting in electric shock and casualties. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a device that will issue a warning when a person approaches a certain range of the high-voltage test area; when the person ignores the warning...
