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
The present invention relates to the five anti-electrolock tools in transformer station and power plant, be specially the hermetically sealed five anti-electrolocks of a kind of intelligent wireless.
Background technology
Shutting device to prevent mistakes in microcomputer generally uses for many years in transformer station, power plant, primarily of anti-error main frame or imitation screen, computer key and supporting five anti-lock compositions, wherein five anti-lockly mainly contains mechanical coding lock and electrolock two kinds.A pair electric contact is had in electrolock, generally be serially connected in the divide-shut brake loop of electric operating equipment and (be generally connected with circuit breaker and isolating switch), as electric blocking contact, only have this contact just can carry out the breaking-closing operating of equipment, computer key there is the electrode column exposed for a pair, electrode column can directly be inserted in electrolock two electrode holes, after computer key identification RFID code-locked is correct, the relay adhesive of computer key inside, connect two exposed electrode posts, make two electric contacts in electrolock connect divide-shut brake loop, realize correct unlocking operation.Because two electric contacts of electrolock are directly exposed in electrode hole, easily by artificial directly short circuit, electrolock is caused to perform practically no function.
Summary of the invention
The present invention, in order to solve the problem that in transformer station and power plant, existing electrolock can be unblanked by artificial short circuit, provides the hermetically sealed five anti-electrolocks of a kind of intelligent wireless.
The present invention adopts following technical scheme to realize: the hermetically sealed five anti-electrolocks of a kind of intelligent wireless, comprise lock body, be provided with single-chip microcomputer in lock body, receive sending module, RFID coded slice and magnetic latching relay and for single-chip microcomputer, receive the battery that sending module and RFID coded slice power, receive sending module to be connected with single-chip microcomputer, the output of single-chip microcomputer is connected with the coil of magnetic latching relay, and the normally opened contact of magnetic latching relay is serially connected in the divide-shut brake loop of electric operating equipment.
With computer key close to electrolock, after the RFID coded slice of computer key identification electrolock, computer key sends unlocking signal (comprising unlock command and retention time in unlocking signal), after receiving sending module reception unlocking signal, single-chip microcomputer adds positive polarity electricity to the coil of magnetic latching relay, the normally opened contact of magnetic latching relay closes, Single-chip Controlling receives sending module and sends unlocking signal, the current state of computer key record electrolock, after the coil losing electricity of magnetic latching relay, the contact of magnetic latching relay also can be kept closed, when arriving the retention time of magnetic latching relay, single-chip microcomputer adds reversed polarity electricity to the coil of magnetic latching relay, the normally opened contact of magnetic latching relay disconnects, Single-chip Controlling receives sending module and sends block signal, the state that computer key record electrolock is current, this electrolock can not direct short circuit, has stopped the phenomenon of artificially arbitrarily unblanking.
The hermetically sealed five anti-electrolocks of above-mentioned a kind of intelligent wireless, also vibrating sensor is provided with in lock body, vibrating sensor is connected with the enabling signal input of single-chip microcomputer, electrolock is when friction shape body, single-chip microcomputer in lock body and reception sending module are in resting state, greatly can reduce the electrical source consumption of electrolock, when unblanking, only need vibrate lock body, single-chip microcomputer can be waken up and receive sending module.
The invention provides the hermetically sealed five anti-electrolocks of a kind of intelligent wireless, this electrolock tool has the following advantages:
1) electrolock is hermetically sealed without lockhole, can not direct short circuit from outside, has stopped the phenomenon of random unblock;
2) employ magnetic latching relay in electrolock, the coil of magnetic latching relay can continue hold mode after dead electricity again, reduces the consumption of power supply in electrolock;
3) electrolock can keep the time of setting according to order or be in long time solution lock status;
4) normal circuit is in low power consumpting state, and battery can continuous operation 5-7.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The hermetically sealed five anti-electrolocks of a kind of intelligent wireless, comprise lock body, be provided with single-chip microcomputer in lock body, receive sending module, RFID coded slice and magnetic latching relay and for single-chip microcomputer with receive the sending module battery of powering, receive sending module to be connected with single-chip microcomputer, the output of single-chip microcomputer is connected with the coil of magnetic latching relay, and the normally opened contact of magnetic latching relay is serially connected in the divide-shut brake loop of electric operating equipment.
The hermetically sealed five anti-electrolocks of above-mentioned a kind of intelligent wireless, be also provided with vibrating sensor in lock body, vibrating sensor is connected with the enabling signal input of single-chip microcomputer.
