Abstract

A security lock based on a 51 single chip microcomputer dialing and alarming system comprises a lock head and a lock body connected with the lock head, wherein the lock head comprises a single chip microcomputer (1) internally provided with a GSM module, a USB interface (2) and a meshing gear (3); the USB interface (2) is connected with the single chip microcomputer (1) through RS232; the axis of a gearing shaft of the meshing gear (3) is arranged as a hexagonal prism lockhole (4), another gearing shaft is connected with a lock cover (6), and the lock cover is positioned above a lock cylinder (5). The security lock has the following advantages: a gear connected with the lock cover is meshed with the gear of a groove of the hexagonal prism, and the lock cover is driven to move mechanically through turn-knob of the groove part to reveal a lock hole, the lock cover is lower than a plane of the lock body, and can only horizontally rotate on the plane of the lock cover, so that the problem of prying opening by external force is solved, the difficulty of opening the security lock by an abnormal means is increased, the chance of stealing is lowered, a needed force of opening the security lock is improved by a lock cover design, and the damage by the means of a master key commonly used by a theft is weakened.

Description

Based on the safety lock of 51 single-chip microcomputer dialing alarm systems

Technical field

The present invention relates to technical field of living goods, specifically a kind of safety lock based on 51 single-chip microcomputer dialing alarm systems.

Background technology

Now, bicycle, battery truck, motorcycle be a kind of extensively the trip mode that adopts by masses.But while bringing convenience to everybody trip, the loss problem of vehicle also brings very large puzzlement to car owner.In a lot of situation, car owner does not know when the car of oneself is lost, and therefore just cannot go the loss preventing car yet.We have researched and developed the safety lock based on 51 single-chip microcomputer dialing alarm systems under this background just, by the warning function of safety lock, make car owner can Timeliness coverage, thus stop vehicle stolen.

Summary of the invention

The object of the invention is to be to research and develop a kind of can available protecting bicycle, battery truck, motorcycle a kind of safety lock based on 51 single-chip microcomputer dialing alarm systems.

A kind of safety lock based on 51 single-chip microcomputer dialing alarm systems of the present invention, comprising: tapered end, and the lock body be connected with tapered end.

Described tapered end, comprising: the single-chip microcomputer of built-in gsm module, USB interface, USB interface is connected by RS232 with single-chip microcomputer, meshing gear, and a gearing shaft axle center of meshing gear is set to six prism lockholes, another gearing shaft connects locking closure, and locking closure is above lock core.

Described lock body, comprising: U-tube, and is wrapped in the charged wire in U-tube.

Described single-chip microcomputer adopts 51 single-chip microcomputers as Central Control Module, and the built-in gsm module of single-chip microcomputer adopts TC35i general on market.

Described locking closure is embedded rotatable metal sheets locking closure, and it is six prism groove keyholes that locking closure covers part.

A kind of safety lock based on 51 single-chip microcomputer dialing alarm systems of the present invention, advantage is: the gears meshing of the gear that shown locking closure connects and shown six prism grooves, is driven the mechanical movement of locking closure, expose lockhole by the turn-knob of groove.Wherein locking closure is lower than lock body plane, can only rotate, solve the problem that external force is pried open in its planar horizontal.And shape, the mechanical property of six special prism office moulding dual lock equipment claim, improve improper means unlocking difficulty, reduce theft probability, improve the requirement of the size of the required power of locking closure design dual lock, weaken the master key means harm power that burglar commonly uses.

Detailed description of the invention

As shown in Figure 2, a kind of safety lock based on 51 single-chip microcomputer dialing alarm systems, comprising: tapered end, and the lock body be connected with tapered end.

Described tapered end, comprising: the single-chip microcomputer 1 of built-in gsm module, USB interface 2, USB interface 2 is connected by RS232 with single-chip microcomputer 1, meshing gear 3, and a gearing shaft axle center of meshing gear 3 is set to six prism lockholes 4, another gearing shaft connects locking closure 6, and locking closure 6 is above lock core 5

Described lock body, comprise: U-tube, and the charged wire 7 be wrapped in U-tube, lock body winding around to be powered maintenance stabling current by internal electric source, electricity condition can be maintained by nominal conditions, now single-chip microcomputer can detect high level, when locking the pressure electric wire experiencing certain and will being cut short destruction, thus circuit is disconnected, what detect is low level, when single-chip microcomputer receives the change of this signal, just to the instruction of TC35i Sending dialled number, vehicle risk information can be provided with this to car owner.

Described single-chip microcomputer 1 adopts 51 single-chip microcomputers as Central Control Module, it mainly contains two functions, one is the voltage detecting lock body institute connecting circuit, once voltage has high-voltage variable to be low-voltage, namely lock is in by scissor state, at this moment second function on locked, namely sends instruction to gsm module, it is dialled;

The built-in gsm module of single-chip microcomputer 1 adopts TC35i general on market, and Main Function dials to user mobile phone under the control of single-chip microcomputer, reminds host vehicle in the hole, thus avoids vehicle stolen.

Described locking closure is embedded rotatable metal sheets locking closure, it is six prism groove keyholes that locking closure covers part, the gears meshing that the gear that locking closure connects is connected with six prism grooves, lock core is made up of common cross lock core, can only rotate in its planar horizontal direction, need by matched key six prism to control locked-cover-switch.

Described USB interface can charge for the lithium battery of safety lock inside, can also be carried out the setting of number in addition, thus make user can carry out setting and the amendment of phone number by USB.

As shown in Figure 1, the workflow of this telephone-type alarm security lock is as follows: after lock body is under pressure the wire disconnection causing locking and lock winding with it, single-chip microcomputer can be touched, thus single-chip microcomputer can to the TC35i Sending dialled number order of gsm module, at this moment gsm module just can carry out dial-up operation, if dial-up success, namely car owner connects phone, single-chip microcomputer just can send and hang up instruction, otherwise will proceed dialing, thus reaches the object of safe early warning.

As shown in Figure 3, the circuit connection diagram of the gsm module of safety lock inside, wherein TC35i is linked together with single-chip microcomputer and sim card slot respectively by expansion slot.18,19 interfaces of TC35i are connected respectively at 11,10 interfaces of single-chip microcomputer in circuit, thus realize serial ports and pass through, and can realize the control of single-chip microcomputer to gsm module.

As shown in Figure 4, the P1^1 interface warning circuit of single-chip microcomputer connects, and P1^1 is input as high level under normal circumstances, and after lock helix circuit is with it cut off, P1^1 is input as low level, and this is that single-chip microcomputer is to gsm module Sending dialled number control command.Simultaneously single-chip microcomputer to be connected the setting and amendment that realize number with wire for PC by USB by RS232.
