Description
Technical field:
The utility model relates to a kind of sensor, and particularly the radio frequency induction lock control sensor of using with a kind of electronic seal is relevant, and it is used for the locked of noncontact radio frequency induction identification of state of oil truck valve under the adverse circumstances and valve off status.
Background technology:
In the existing all types of sensor, major part can't be applicable in the valve management and control of oil truck, and the sensor applicatory of small part can only adopt the mode of induction to monitor, the mode that can't further adopt lock control is carried out enforceable monitoring to the switch of valve, and the most employing of this sensor is the mode of magnetic signal induction, easy crack substitutes, and is badly in need of a kind of noncontact inductive mode unique coding, that be difficult for cracking that possesses.In addition, because the valve place work under bad environment of oil truck, and belong to the explosive gas atmosphere of high-risk, require sensor to have explosion-proof performance, so also do not have a sensor that goes for the oil truck valve and the oil truck valve is implemented unique coding induction and enforcement lock control on the market present.
Summary of the invention:
At the problems referred to above, the utility model provides a kind of radio frequency induction lock control sensor, go for the oil truck valve and the oil truck valve is implemented unique coding induction and enforcement lock control, be applicable to the explosive gas atmosphere of oil truck valve, has anti-greasy dirt corrosion simultaneously, performances such as anti-car body vibrations.
For reaching above-mentioned purpose, the technical solution of the utility model is:
Electronic seal comprises mechanical driving part and electronic circuit control part with radio frequency induction lock control sensor, and described mechanical driving part comprises lock shaft, and lock shaft is provided with magnet steel and radio-frequency card, is provided with detent in a side of lock shaft; One driven by motor, one lock pin inserts or to break away from the detent control lock shaft lock of lock shaft dead and open.
Described electronic circuit control partly comprises: single-chip microcomputer: received signal and send instruction; Serial bus module: connect single-chip microcomputer, carry out the transmitting-receiving transmission of data; The radio frequency induction module: connect single-chip microcomputer, single-chip microcomputer reads the signal of radio frequency induction module; Magnetic group induction module: connect single-chip microcomputer, cooperate the radio frequency induction module, single-chip microcomputer reads the signal of magnetic group induction module; Motor control module: connect single-chip microcomputer, control motor-driven and motor range identification; Intrinsically safe circuit: it cooperates its safe operation under the explosive gas atmosphere of high-risk of guarantee with above-mentioned each module.
Adopt technique scheme, what the utility model adopted is that machinery and electronics cooperatively interact to realize that noncontact induction identification and valve shut locked mode, the order data that single-chip microcomputer is received according to serial bus module removes to discern the signal and the magnetic induction signal of radio frequency induction module, by after the computing motor control module being sent instruction, it is used for the locked of non-contact magnetic inductive identification of oil truck valve state under the adverse circumstances and valve off status.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model embodiment mechanical driving part structural representation;
Fig. 2 is the utility model embodiment electronic circuit control part-structure schematic diagram.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described in detail:
As shown in Figure 1 and Figure 2, electronic seal comprises mechanical driving part 1 and electronic circuit control part 2 with radio frequency induction lock control sensor, and described mechanical driving part 1 comprises lock shaft 11, lock shaft is provided with magnet steel 12 and radio-frequency card 13, is provided with detent 14 in a side of lock shaft 11; One motor 15 drives that a lock pin 16 inserts or to break away from the detent 14 control lock shafts 11 of lock shaft locked and open.
Described electronic circuit control part 2 comprises: single-chip microcomputer 21: be responsible for program implementation and operation of data and transmitting-receiving; Serial bus module 22: connect single-chip microcomputer, adopt the serial bus protocol of autonomous Design, the transmitting-receiving of carrying out data transmits; Radio frequency induction module 23: connect single-chip microcomputer, adopt ISO/IEC 14443 A agreements, have the function of unique number and password encryption; Single-chip microcomputer reads the signal of radio frequency induction module; Magnetic group induction module 24: connect single-chip microcomputer, as the aid identification signal of radio frequency induction module, make the signal identifying further rigorous, single-chip microcomputer reads the signal of magnetic group induction module; Motor control module 25: connect single-chip microcomputer, comprise the identification of motor-driven and motor range; Intrinsically safe circuit 26: it cooperates with above-mentioned each module, mainly is safety protection circuit, is used to ensure that sensor can safe operation under the explosive gas atmosphere of high-risk.
The concrete course of work is as follows:
Carry out when shutting action, to shift lock shaft 11 onto position forward earlier, make radio-frequency card 13 and magnet steel 12 arrive position accurately, there is supporting radio-frequency module to read the information of radio-frequency card and the signal that puts in place that hall device is discerned magnet steel in this position, receive by serial bus module 22 then and shut order, single-chip microcomputer 21 reads the signal that puts in place of radio frequency induction module 23 and magnetic group induction module 24, whether differentiate valve shuts, if shut, single-chip microcomputer sends instructions for 21 times to motor control module 25, motor 15 action counterclockwise is inserted in the detent 14 lock pin 16, this time, lock pin 16 just in time blocked lock shaft 11, and lock shaft 11 just in time blocks valve forward when pushing away, thereby realizes locking to valve, reaches the purpose of lock control.If valve does not shut, single-chip microcomputer 21 can remind the operator that the lock shaft of valve is shifted onto the position by sending out information on the serial bus module 22 after by the identification of radio frequency induction module 23 and magnetic group induction module 24 signals.
When carrying out unlocking action, issue unlock command by serial bus module 22 and give single-chip microcomputer 21, single-chip microcomputer issues unlock instruction by motor control module 25, motor 15 action clockwise makes lock pin rotate disengaging detent 16, this time, lock shaft 11 just can not blocked by lock pin 16, the operator just can draw back lock shaft, thereby removes the locking state to valve.
What the utility model adopted is that machinery and electronics cooperatively interact to realize that noncontact induction identification and valve shut locked mode, the order data that single-chip microcomputer is received according to serial bus module removes to discern the signal and the magnetic induction signal of radio frequency induction module, by after the computing motor control module being sent instruction, the drive motors action; Go for the oil truck valve and the oil truck valve is implemented unique coding induction and enforcement lock control, safer, reliable.
