Problems solved by technology

This intelligent fence alarm system has the advantages of high alarm accuracy and strong video capture. However, the fence structure of the intelligent fence alarm system still adopts the traditional fence. The alarm signal will only be issued after being stepped on to a certain extent, and the mechanical structure of the entity is inconvenient to arrange and easy to damage

specific Embodiment 1

[0016] Such as figure 1 As shown, an infrared warning system for safe operation of the power grid to prevent mistaken entry into the electrified interval includes the infrared monitoring device 4 and the warning device. The flashing safety sign 2 is set, and the infrared monitoring device 4 and the warning device are connected with the controller 3 signals respectively. Search device.

[0017] The infrared monitoring device 4 is arranged at the boundary of the safe distance range outside the electrified isolated area.

[0018] The warning device includes an on-site sound and light alarm 5, a voice player 6 and a remote monitoring sound and light alarm.

[0019] The infrared monitoring device 4 is wirelessly connected with the controller 3 .

[0020] The controller 3 is an integrated control chip, and the control chip is connected with a wireless signal transceiver 7 .

[0021] The intelligent searchlight device includes a tracker 8 and a searchlight 9 at the top of the ala...

specific Embodiment 2

[0023] The difference from the first embodiment is that the controller 3 includes a control host, which is a networked five-proof microcomputer.

[0024] In the present invention, several groups of infrared beam emitters and infrared beam receivers are arranged at a certain safe distance outside the electrified isolation area, especially carefully arranged at the door of the electrified isolation area, to form an infrared monitoring light barrier or a light wall, and to prevent the charged The interval realizes strict online automatic monitoring. Once someone strays into the electrified interval, the on-site sound and light alarm device and the remote monitoring sound and light alarm device are activated at the same time, reminding the control room personnel and on-site operators that someone strays into the dangerous electrified interval for emergency treatment. The on-site acousto-optic warning device and the voice player warn that the person who enters by mistake must return...

Abstract

The invention discloses an infrared warning system capable of ensuring the safe operation of an electric grid and preventing an electrified chamber from being entered mistakenly. The infrared warning system capable of ensuring the safe operation of the electric grid and preventing the electrified chamber from being entered mistakenly comprises an infrared monitoring device and a warning device, wherein the warning device is arranged on a warning rod at a high position, flashing safety marks are arranged on the rod body of the warning rod, the infrared monitoring device and the warning device are respectively in signal connection with a controller, the infrared monitoring device comprises multiple sets of infrared beam transmitters and infrared beam receivers, and the warning device is connected with an intelligent searchlight device. An infrared monitoring light fence or light wall is formed by the infrared beam transmitters and the infrared beam receivers to achieve strict automatic on-line monitoring on the electrified chamber, the warning device can be started intelligently to prompt emergency handling, and personnel mistakenly entering the electrified chamber are warned to retreat to a safe range by the field audible and visual warning device and a voice player. According to the infrared warning system capable of ensuring the safe operation of the electric grid and preventing the electrified chamber from being entered mistakenly, the laser transmitting technology and the intelligent searchlight device are combined ingeniously, the wireless communication technology is combined, and the intellectuality and the accuracy of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of power system safety measures and devices, and in particular relates to an infrared alarm system used for the safe operation of a power grid to prevent mistaken entry into charged intervals. Background technique [0002] At present, in the power grid system, interval maintenance and overhaul of high-voltage substation equipment are inevitable. Once someone operates in violation of regulations and strays into the electrified interval, it will cause vicious and serious accidents such as personal injury and death. Sparse safety measures are taken to prevent the occurrence of accidental entry into the charged interval, to ensure the safe and stable operation of the power grid and electrical equipment and the personal safety of the staff. However, conventional warning lights are difficult to work in the process of use, and there are still great potential safety hazards. Cases of safety accidents and lessons...
