Description

Car Burglar Alarm able to programme

Technical field

The utility model relates to a kind of Car Burglar Alarm, can be by the Car Burglar Alarm able to programme of incoming signal programming in particular for motor bike, automobile, battery-driven car etc.

Background technology

Traditional lockset that is used for motor bike, automobile etc. is easy to be destroyed by the offender; in case it is destroyed; just do not have the effect of protection vehicle; and electronic safety lock is stronger to the dependence of electricity; in case with supply disconnecton; anti-theft feature just can disappear, and the remote controller of the electronic anti-theft device that has can use mutually, and the offender just has an opportunity to take advantage of.

The utility model content

The utility model technical issues that need to address provide a kind of Car Burglar Alarm, and this Car Burglar Alarm energy delinquency prevention molecule sledge lock, trimming start vehicle, even Car Burglar Alarm is destroyed, can not start vehicle, reach thief-proof purpose.

For achieving the above object, technical solution adopted in the utility model is:

A kind of Car Burglar Alarm able to programme, comprise the programming signal input circuit, the signal conditioning output circuit, the input end of the output termination signal conditioning output circuit of programming signal input circuit, by gear, turn to, light, brake, the programming signal that one or several signal of switch such as loudspeaker or position signal is formed connects the input end of the programming signal input circuit of Car Burglar Alarm, the mouth of signal conditioning output circuit is that the mouth of Car Burglar Alarm is a group or several groups of normally-open normally-close points of relay, with flameout switch, electronics oil pump and ignition wire serial connection, and connect or go here and there and connect and be combined into line output programming.

Above-mentioned signal conditioning output circuit is made up of spurious signal relay latching circuit and correct signal relay control output circuit, the spurious signal relay latching circuit of signal conditioning output circuit is by the normally closed contact KA23 of relay K A2, after contacting successively, relay K A1 coil and relay K A1 open contact KA11 be connected between the power positive cathode, the mistake incoming signal is connected on the node of relay K A1 coil and open contact KA11, correct signal relay control output circuit by relay K A2 open contact KA21 with after relay K A3 open contact KA31 is in parallel with the coil of relay K A2, after connecting successively, the normally closed contact KA13 of relay K A1 is connected between the power positive cathode, the each point of another group normally-open normally-close point KA20 of relay K A2 connects output line, the coil one termination power negative pole of relay K A3, the correct signal of another termination input.

Adopt the beneficial effect that technique scheme produced to be: because the utility model is used motor bike, gear on the bodies such as automobile, turn to, the switch of brake etc. or position signal are as the incoming signal of Car Burglar Alarm, the car owner can simply make up (programming) with the needs and the custom of these signals bases oneself, have only when importing correct signal (configuring), vehicle could start, otherwise, the Car Burglar Alarm self-locking, vehicle can not start, if Car Burglar Alarm is destroyed, then start-up system is destroyed thereupon, be difficult at short notice start-up system is recovered, anti-theft and anti-robbing is effective, and the utility model is made simple, with low cost, crack very difficult, anti-theft and anti-robbing misfortune effect is obvious, even Car Burglar Alarm is destroyed, also can play antitheft effect.

Fig. 3 is the utility model schematic circuit diagram.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As shown in Figure 1, the utility model comprises programming signal input circuit, signal conditioning output circuit, the input end of the output termination signal conditioning output circuit of programming signal input circuit, the signal conditioning output circuit is made up of the spurious signal relay latching circuit and the correct signal relay control output circuit of interlocking.

As shown in Figure 2, the spurious signal relay latching circuit of signal conditioning output circuit is by the normally closed contact KA23 of relay K A2, after contacting successively, relay K A1 coil and relay K A1 open contact KA11 be connected between the power positive cathode, the mistake incoming signal is connected on the node of relay K A1 coil and open contact KA11 by diode D, correct signal relay control output circuit by relay K A2 open contact KA21 with after relay K A3 open contact KA31 is in parallel with the coil of relay K A2, after connecting successively, the normally closed contact KA13 of relay K A1 is connected between the power positive cathode, the each point of another group normally-open normally-close point KA20 of relay K A2 connects output line, the coil one termination power negative pole of relay K A3, the correct signal of another termination input.

As shown in Figure 3, wrong incoming signal IN1 to IN9 able to programme is respectively on the node of the coil by being connected to relay K A1 behind the diode D1-D9 and open contact KA11, relay K A2 normally closed contact KA23, relay K A1 coil, after connecting successively, relay K A1 open contact KA11 is connected between the power positive cathode, relay K A2, KA3, an end is by relay K A1 normally closed contact KA13 power connection positive pole behind the coils from parallel connection of coils of KA4, the open contact KA51 of the other end and relay K A5 with join with a end after the open contact KA21 of relay K A2 is in parallel again after the open contact KA61 of relay K A6 connects, the open contact KA51 of relay K A5 with after the open contact KA61 of relay K A6 connects again with other end power connection negative pole after the open contact KA21 of relay K A2 is in parallel, relay K A5, the coil one termination power negative pole of KA6, another termination correct signal able to programme, relay K A3, the normally-open normally-close point KA30 of KA4, the each point of KA40 meets output point OUT1-OUT6 able to programme respectively.

Principle of work: when starting locomotive, the user is with gear, brake etc. places the tram of having programmed, correct signal input end incoming signal, relay K A5, the KA6 adhesive, its open contact KA51, the KA61 closure, relay K A2, KA3, the KA4 adhesive is by the open contact KA21 self-locking of relay K A2, relay K A3, the normally-open normally-close point action of KA4, make the output line of finishing journey be communicated with start-up circuit, can start vehicle, if the user has given spurious signal when operating, then relay K A1 adhesive, and self-locking, relay K A1 normally closed contact disconnects, and causes KA3, KA4 can not adhesive, the user can not start vehicle, have only cancelling self-locking after the power supply disconnection, have only by correct programming mode and guarantee not have to start vehicle under the situation of wrong incoming signal.
