Abstract
The utility model provides an on-off controller capable of identifying identity, which comprises a radio frequency identification label and a reader. The on-off controller is characterized in that a signal output interface of the reader is connected with a signal input end of a microprocessor, and a signal output end of the microprocessor is connected with an input end of a relay module; and the relay module is connected into an anti-explosion on-off control circuit in series. The on-off controller can employ equipment operating personnel with certificates, thereby completely eradicating the operation without certificates; electromechanical equipment can not be operated until the condition is accorded, so that the security is improved; the controller is directly connected into the anti-explosion on-off control circuit, and can not change the structure, the function and the operation custom of the original anti-explosion on-off switch. The on-off controller has a memory function, can memorize related records of personal operation within a certain time slot, and can output data by the infrared or the other modes for managers to query.
Description
Technical field
The utility model belongs to the control assembly of explosion-proof switch under a kind of coal mine, particularly a kind of controller of radio-frequency (RF) identification operator's identity.
Background technology
Coal mining technology, recovery method are constantly progressive at present, and the down-hole electromechanical equipment is more and more, and the mining machinery level is greatly improved.But the generality along with equipment is used also exposes a problem, and the phenomenon of not operation personnel operation often takes place, and has very large potential safety hazard, and the personal injury that causes thus happens occasionally.Utilize the RFID REID, obtain operating personnel's information, the identification identity really stops not have the card operation, phenomenon such as operation is avoided the generation of personal injury privately.
The utility model content
The purpose of this utility model provides a kind of on-off controller of discerning identity, realization has only qualified personnel (individual or colony) through ability opening device after the identification to operator's identification, operates, improve fail safe, avoid the generation of personal injury.
The purpose of this utility model is achieved in that and comprises RFID tag, reader, it is characterized in that: the signal output interface of reader connects the signal input part of microprocessor, the signal input part of microprocessor connects the relay module input, and relay module is concatenated in the explosion-proof switch control circuit.RFID tag is carried out exchanges data by radio wave and reader, and the energy of work is to be provided by the radio-frequency pulse that reader sends.Reader offers microprocessor with the information that reads, and little processing is handled the information that reads, and after the processing result is issued relay module.Equipment operator (individual or colony) utilizes RFID tag (employee operates card) after scanning on the reader, whether microprocessor judges satisfies condition, when satisfying condition, relay module makes the control circuit contact be in closure state, and equipment is start-stop normally; When not satisfying condition, the control loop contact is in off-state, and equipment can not be opened.
The utility model has the advantages that:
1, realizes that the equipment operator takes appointment with certificate, stop not have card operation phenomenon.The personnel that only have respective identity (qualification) when eligible, can operate electromechanical equipment through identification, improve fail safe.
2, by colony's identification, stop to operate privately phenomenon.Have many people interlock, when certain equipment needs several people simultaneously during on the scene can the startup, after only meeting everyone that impose a condition and discerning identity, equipment could start.
3, this controller directly inserts the explosion-proof switch control circuit, does not change original explosion-proof switch structure, function and operating habit.
4, have memory function, can store the relative recording of certain hour section personnel operation, utilize infrared or other modes realize data output, for administrative staff's inquiry.
5, utilize this device to combine, realize switch (equipment) location with assigned personnel's navigation system.
Description of drawings
Fig. 1 can discern identity on-off controller circuit structure diagram.
Embodiment
See Fig. 1, the utility model is provided with RFID tag (employee operates card) 1, reader 2, the signal output interface of reader 2 connects the signal input part of microprocessor 3, the signal output part of microprocessor 3 connects the input of relay module 4, and relay module 4 is concatenated in the explosion-proof switch control circuit.Each several part element described in the utility model is prior art.
Operation principle of the present utility model:
On original explosion-proof switch control loop, get contact KM2, this controller is concatenated on the explosion-proof switch control loop by contact KM2.Before the operation isolating switch QS is pulled make position, the explosion-proof switch control loop is in running order.Operating personnel (individual or colony) hold RFID tag 1 (employee operates card) near reader 2, RFID tag 1 is carried out exchanges data by radio wave and reader 2, the energy of RFID tag 1 work is to be provided by the radio-frequency pulse that reader 2 sends, reader 2 is transferred to microprocessor 3 with the identity information that reads, and microprocessor 3 judges according to imposing a condition whether the identity information that reads meets.When qualified personnel or colony utilize RFID tag (employee operates card) 1 after scanning on the reader 2, the personnel identity information that reads is judged according to imposing a condition by microprocessor 3, and relay module 4 is sent command adapted thereto.When satisfying condition, relay module 4 makes switch control circuit contact KM2 be in closure state, and operating personnel press switch activated button SB, the control loop closure, and explosion-proof switch vacuum contactor KM1 adhesive, equipment normally starts running; Press stop button SBS when stopping, control loop disconnects, the vacuum contactor KM1 release of cut off the power supply, and the circuit disconnection, equipment shuts down.When identity information does not meet when imposing a condition, relay K M2 is failure to actuate, and switch control circuit contact KM2 is in off-state, operating personnel are during by switch activated button SB, because of control loop is in off-state, explosion-proof switch vacuum contactor KM1 can not adhesive, and equipment can not start.
Claims (1)
1. can discern the identity on-off controller for one kind, comprise RFID tag, reader, it is characterized in that: the signal output interface of reader connects the signal input part of microprocessor, and the signal output part of microprocessor connects the input of relay module.
