Wireless intelligent omni-sealed five-prevention electric lock

Abstract

The invention relates to a five-prevention electric lockset of a transformer substation or a power plant, particularly to a wireless intelligent omni-sealed five-prevention electric lock comprising a lock body. A single-chip microcomputer, a receiving-transmitting module, an RFID encoding plate, a magnetic latching relay, and a battery for powering the single-chip microcomputer and the receiving-transmitting module are arranged in the lock body. The receiving-transmitting module and the single-chip microcomputer are connected; the output terminal of the single-chip microcomputer is connected with a coil of the magnetic latching relay; and a normally-open contact of the magnetic latching relay is connected in series to an opening-closing loop of an electric operation device. A vibrating sensor is arranged in the lock body and is connected with a starting signal input terminal of the single-chip microcomputer. The electric lock uses the RFID encoding plate as a locking code and after a computer key identifies the lock code, an unlocking command is emitted. The electric lock enables two electric contacts to be connected; and because the two electric contacts of the electric lock are not exposed at the panel, the human direct short circuit phenomenon can be prevented. Therefore, a problem that the original electric lock performs practically no function can be solved.

Description

technical field [0001] The invention relates to a five-proof electric lock for substations and power plants, in particular to a wireless intelligent fully sealed five-proof electric lock. Background technique [0002] The microcomputer anti-misoperation locking device has been widely used in substations and power plants for many years. It is mainly composed of an anti-mistake host computer or an analog screen, a computer key and matching five-proof locks. The five-proof locks mainly include mechanical coded locks and electric locks. There is a pair of electrical contacts in the electric lock, which are generally connected in series in the opening and closing circuit of the electric operation equipment (usually connected with a circuit breaker and an isolating switch), as an electrical locking contact, and only when this contact is connected can the opening and closing operation of the equipment be performed , There is an exposed electrode column on the computer key, which ca...
