Embodiment Construction

[0013] A wireless intelligent fully-sealed five-proof electric lock, comprising a lock body, the lock body is provided with a single-chip microcomputer, a receiving and sending module, an RFID encoding sheet and a magnetic latching relay, and a battery for powering the single-chip microcomputer and the receiving and sending module, and the receiving and sending module is connected to the single-chip computer, The output end of the single chip microcomputer is connected with the coil of the magnetic latching relay, and the normally open contacts of the magnetic latching relay are connected in series in the opening and closing circuit of the electric operation equipment.

[0014] In the above-mentioned wireless intelligent fully sealed five-proof electric lock, a vibration sensor is also arranged in the lock body, and the vibration sensor is connected to the start signal input end of the single-chip microcomputer.

[0015] During specific implementation, the model of the single-c...

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...
