A kind of intelligent sealing tape lockTechnical field
The present invention relates to intelligent lock field, specifically a kind of intelligent sealing tape lock.
Background technology
Need to ensure cargo security during long-distance cargo transport, to prevent goods is stolen or is exchanged just to must be prevented from transportingDuring compartment or other rigid packages（Such as container, container car, oil truck, car of declaring dutiable goods, cash box）It is unauthorizedOpen, use the form of sealing tape lock in existing method mostly.
The form of sealing tape lock has many kinds at present, and common mainly has bullet envelope, steel wire plastic packaging, iron sheet seal, plastic seal, preventsSteal lead sealing, common envelope etc., but no matter which kind of sealing tape lock form, be all mechanical one-time lock, function is single, it is impossible to examinesThe conveying arrangement for transporting casing is surveyed, particularly when casing is opened without permission or lockset itself damages, also can notDetection in time simultaneously issues broadcast to manager.
The content of the invention
For solve the problems, such as during existing sealing tape lock use function it is single, can not automatic sensing lockset state, the present inventionThere is provided it is a kind of can be with the intelligent sealing tape lock of automatic detection lock pin state.
The present invention concrete scheme be：A kind of intelligent sealing tape lock, there is separate and matching used lock tube and lock pin,The lock tube has the sheath body that upper end is opening, the jump ring for clamping lock pin is provided with sheath body, returning apparatus is useful in sheath bodyThe sensing device of envelope state is applied in automatic detection lock pin；The lock pin has base, and decorative pearl on top of an official cap formula lock pillar is provided with base, sensingDevice acts under the triggering of decorative pearl on top of an official cap formula lock pillar, and sends lock pin to far-end receiver and apply envelope status information.
Sensing device of the present invention has the main control chip installed in lock tube sheath body intracavity bottom, for sending master controlThe communication module and be the main control chip and the power supply of communication module power supply that chip is broadcasted, have feeling of stress on main control chipModule is answered, reed is connected with pressure sensitive module, the action message of reed by pressure sensitive module collection and passes through master controlAfter chip processing, communication module is sent to, and sent to long-range receiving terminal by communication module.
Pressure sensitive module of the present invention comprises at least pressure sensor, optoelectronic switch and magnetic switch.
Sensing device of the present invention also includes being used for the locating module for detecting strip of paper used for sealing lock position, and the locating module willThe positional information of collection is sent to communication module and long-range receiving terminal.
Communication module of the present invention is at least in a manner of bluetooth or WiFi or NB-IoT or LoRa or GPRS and long-rangeReceiving terminal is communicated.
Decorative pearl on top of an official cap formula lock pillar of the present invention is provided with central through hole, and the bottom end opening of central through hole is encapsulated on base, onThe edge of end opening inwardly collapses, and the diameter of upper end open is less than the diameter of central through hole, sliding in the central through hole of lock pillarThe dynamic decorative pearl on top of an official cap for being set with diameter and being more than upper end open, central through hole is interior to be also equipped with thimble, the top between the decorative pearl on top of an official cap and basePearl is clamped at the upper end open of central through hole under the thrusting action of thimble.
Central through hole is provided with lock pillar of the present invention, the bottom end opening of central through hole is encapsulated on base, and upper end is openedThe edge of mouth inwardly collapses, and the diameter of upper end open is less than the diameter of central through hole, is slided in the central through hole of lock pillar tightIt is more than the decorative pearl on top of an official cap of upper end open equipped with diameter, gas, gas is filled with the interior vestibule between the decorative pearl on top of an official cap and base of central through holeBody caused pushing tow pressure in central through hole vestibule is not less than the gravity of the decorative pearl on top of an official cap.
Connect band is provided between the bottom of lock tube and lock pin of the present invention, in order to which lock tube and the supporting of lock pin makeWith.
The present invention operation principle be：
1st, the connect band between lock tube and lock pin is cut, is made in lock pillar insertion lock tube by the base of lock pin upward；
2nd, during insertion, lock pillar Extruding spring plate type power switchs, and the power supply in lock tube is powered, and now activates master control corePiece, communication module and locating module；
3rd, lock pillar continues into, until the decorative pearl on top of an official cap of lock pillar front end is touched and pushes down on reed, reed triggering pressure sensitive module,Now, the pin level rise being connected on main control chip with pressure sensitive module, main control chip are inquired on the voltage of the pinRise and sent by communication module to long-range receiving terminal and broadcasted, while locating module is sent out also by communication module to long-range receiving terminalSend positional information；
4th, when cargo movements arrive at or open privately without permission, the base of lock pin is cut：
1. use thimble structure inside lock pillar, thimble loses the support of base, and the decorative pearl on top of an official cap disappears to the pushing force of reed, reedDeformation recovers, and the decorative pearl on top of an official cap is upspring, and pressure sensitive module can not sense that reed changes, and pressure sensitive module draws on main control chipPin level reduces, and communication module and locating module no longer send to long-range receiving terminal and broadcasted；
2. use inflatable structure inside lock pillar, after base is cut, gas is discharged in lock pillar central through hole, and the decorative pearl on top of an official cap is to reedPushing force is disappeared, and reed deformation recovers, and the decorative pearl on top of an official cap is upspring, and pressure sensitive module can not sense that reed changes, on main control chipThe pin level of pressure sensitive module reduces, and communication module and locating module no longer send to long-range receiving terminal and broadcasted.
The advantage that the present invention possesses is：
1st, installed additional in traditional sealing tape lock and perceive the automatic detection device that lock tube applies envelope state with lock tube, and by lock tube with lockingSet envelope state of applying be delivered to remote control center, realize administrative staff sealing tape lock is applied envelope state all the period of time it is seamlessSupervision, solves the problems, such as not knowing whether casing is illegally opened in transportation, while also apply sealing tape lock envelope stateIt is made that and gives warning in advance；
2nd, install locating module additional in lock tube, realize the real-time positioning to strip of paper used for sealing lock position in transportation, realize pairThe real-time tracing of cargo movement track, it is easy to user in Terminal Server Client to the defeated state of goods and looking into real time for geographical positionAsk；
3rd, sealing tape lock is applied into envelope state and positional information in a manner of broadcast singal to be transmitted to long-range receiving terminal, for long-range visitorFamily end is further deeply handled strip of paper used for sealing lock information（Such as internet+and big data platform）Lay a good foundation；
4th, the structure design of intelligent sealing tape lock is simple in the present invention, and mass production processing and manufacturing cost is low, possesses fabulous market and pushes awayWide prospect；
5th, intelligent sealing tape lock after the cutting of lock pin base, can carry out recycling to the sensing device in lock tube in the present invention,Reduce manufacturing cost.
