Description

Electricity-saving type family expenses Radio Frequency ID combination padlock

The utility model technical field

The utility model relates to electricity-saving type family expenses Radio Frequency ID combination padlock.

The utility model technical background

Lock body is of a great variety, at present, people are extensive use of the radio frequency combination padlock, in the prior art, ID number (electronics) lock based on the RFID technology appears on the market, but in domestic. applications, can utilize the Radio Frequency ID combination padlock of dry cell power supply still not have Application and Development, its main cause be RFID to read the decoding circuit power consumption big, be not suitable for the dry cell power supply place.Simultaneously, existing combination padlock, it is read yard module and is in "on" position for a long time, thereby energy consumption is bigger, and it is unreasonable to read the set-up mode of yard coil, and in addition, the safety of prior art and reliability are still waiting to improve.

The technical solutions of the utility model general introduction

The purpose of this utility model provides a kind of electricity-saving type family expenses Radio Frequency ID combination padlock.

The purpose of this utility model is achieved in that

The utility model comprises lock body, electric-magnetic lock mechanism and mechanical return mechanism, one reads a yard coil is arranged at the tapered end front end, one RFID chip is embedded in the standard machinery key, one key inserts sense switch and is placed on the tapered end outer ring, in lock body, be provided with and read decoding circuit, supervisory circuit and supplying cell, the pickup arm that described key inserts sense switch stretches in the key of lock gall, it is described that to read yard coil coaxial with tapered end, described key inserts sense switch and reads yard coil two lead-out wires respectively, is connected on monitoring module and the RFID base station module.

The utility model monitoring module is powered to the RFID base station module by the PWR pin, one of two lead-out wire that key inserts sense switch insert monitoring module, another root ground connection, read ANT1 pin that inserts the RFID base station module of two lead-out wires of yard coil, another root inserts the ANT2 pin of RFID base station module, the DATA of RFID base station module and monitoring module, CTRL pin correspondence is joined.

Because the utility model has adopted technique scheme, the power consumption problem of Radio Frequency ID digital code electronic lock under the idle condition will be solved, read the placement of yard coil a yard process power consumption is read in reduction, thereby constitute a kind of electricity-saving type scheme, can reach the following power consumption below 10 microamperes of holding state.Cooperate electric-magnetic lock mechanism and the corresponding mechanism resetting-mechanism technology applied for a patent in addition, can improve the safety and the reliability of Radio Frequency ID combination padlock greatly, the utility model allows to use two-sided key.

When unblanking, after the ID digital key inserts the key hole, connect key earlier and insert sense switch, send and detect the key cipher control signal, the lock inner microcomputer is connected the power supply that ID reads yard module after receiving this signal, and by reading the digital code information in yard coil collection ID digital key, sends this digital code information to the lock inner microcomputer and differentiate, send " unblanking " instruction after being judged as legal unblanking, need only shaped as key bit and correctly can unblank this moment; Send " locking " instruction after (not detecting the situation of encrypted message or information errors) if unblank through being judged as illegally, by electric-magnetic lock mechanism that door lock master dead bolt is stuck, even shaped as key bit correctly also can't be unblanked.After the ID digital key was extracted from the key hole, the power supply that radio frequency I D reads yard module is outage thereupon also, and after this circuit enters holding state in the lock, and the complete machine power consumption is below 10 microamperes, thereby reached the purpose that reduces power consumption, became a kind of radio frequency combination padlock of electricity-saving type.

This electricity-saving type Radio Frequency ID number (electronics) lock is suitable for dry cell power supply, thereby can be widely used in the family expenses occasion of low power consumption requirement.

Fig. 2 is the utility model circuit structure schematic diagram.

The utility model embodiment

Below in conjunction with Fig. 1～Fig. 2 and embodiment in detail the utility model is described in detail.

Shown in Fig. 1～2:

The utility model comprises lock body, electric-magnetic lock mechanism and mechanical return mechanism, one reads the front end that yard coil 1 is arranged at tapered end, one RFID chip 2 is embedded in the standard machinery key 3, one key inserts sense switch 4 and is placed on the tapered end outer ring, in lock body, be provided with and read decoding circuit, supervisory circuit and supplying cell, described key inserts sense switch pickup arm 5 and stretches in the key of lock gall 6, it is described that to read yard coil 1 coaxial with tapered end, described key inserts sense switch 4 and reads yard coil 1 two lead-out wires respectively, is connected on monitoring module 7 and the RFID base station module.The utility model monitoring module is powered to the RFID base station module by the PWR pin, one of two lead-out wire that key inserts sense switch 4 insert monitoring module, another root ground connection, read ANT1 pin that inserts the RFID base station module of two lead-out wires of yard coil, another root inserts the ANT2 pin of RFID base station module, the DATA of RFID base station module and monitoring module, CTRL pin correspondence is joined.

When key does not insert, have only supervisory circuit work, read decoding circuit and do not work.When unblanking or lock, because need key to realize the operation of unblanking or locking, so settle a key to insert sense switch in tapered end, this switch is as a sensor of supervisory circuit, and monitoring circuit detects the action of this switch.When key inserts keyhole, to touch key and insert sense switch, supervisory circuit is then connected the power supply of reading decoding circuit, reads sign indicating number and open and close latching operation.

The RFID chip is embedded in the plastics handle of standard machinery key, and key is not there being metallic shield, so that electromagnetic wave penetrates.The pickup arm of switch reaches in the key of lock gall, guarantees when key does not insert, and key inserts sense switch and is in off-state; When key inserted, key inserted sense switch and is in on-state, and does not influence the rotation of lock gall.It is coaxial with tapered end to read yard coil block, is provided with a nonmetal cover cap and plays fixing, protection and decorative effect outside tapered end.

Electric principle of the present utility model is: under the state that key does not insert; key inserts sense switch and disconnects; monitoring module is in stopped status, and the RFID base station module is in complete off-position, can control to shutdown electric current below 10 microamperes to entire circuit like this.When key inserted, key inserted sense switch (with ground) and connects, and wakes monitoring module up, monitoring module is powered to the RFID base station module by the PWR pin, treat the RFID base station module power on stable after, send out control command by CTRL to the RFID base station module, and read the ID sign indicating number of key from DATA.Read sign indicating number correct after, if key is not extracted, the RFID base station module is controlled to standby mode, to reduce power consumption, after key is extracted, then close the power supply of RFID base station module.

The electric-magnetic lock mechanism of lock body and corresponding mechanical return mechanism apply for a patent in addition, and this manual is no longer introduced, and can consult relevant manual.
