Problems solved by technology

One of the main problems existing in the existing five-proof system is: the five-proof socket has a large structure size, takes up a lot of space on the screen, and is easy to be bypassed by short-circuiting the terminal and loses the function of preventing false locking. It is safe and reliable. Low sex

Abstract

The invention relates to an electronic key jack-type five-prevention socket which comprises a single-chip microcomputer, a voltage-stabilized power module and a jack-type socket body. The number of poles of the jack-type socket body is at least four, and the four poles are connected to a serial communication port of the single-chip microcomputer, power output of the voltage-stabilized power module and a measuring pin and a grounding pin of the single-chip microcomputer respectively. The socket can be used in cooperation with a plug-type Bluetooth serial port electronic key, five preventions are controlled and a relay is allowed to be switched on in the mode that the electronic key and the socket conduct serial port communication, a device number containing specific serial port message is sent to the socket through smartphone five-prevention APP software, and therefore the function of preventing misoperation is achieved.

Description

technical field [0001] The invention relates to a locking device for preventing misoperation of electrical equipment, in particular to an electronic key jack type five-proof socket. Background technique [0002] In the switching operation or maintenance operation of the substation operation mode, it is often necessary to continuously operate multiple primary devices such as switches and knife switches. In order to prevent misoperation, the substations are equipped with a five-proof system. The operation and maintenance personnel first perform simulated operations on the simulation disk or the five-proof computer according to the operation ticket, and the simulation disk or the five-proof computer will download the primary device number to the five-proof system in the order of operation. Anti-key, the operation and maintenance personnel then hold the five-proof key and insert it into the five-proof socket on the operation screen of the primary equipment on site. At this time...
