Abstract
The utility model discloses an agricultural machinery and implement anti-theft alarm circuit, which comprises a power supply, a control switch, a mercury switch, a PWM controller, a relay, a dynamically closed contact of the relay, a music chip and a loudspeaker which are sequentially connected, wherein the power supply is connected with the PWM controller and the relay through the control switch, the music chip and the loudspeaker are connected with one end of the dynamically closed contact of the relay, and the other end of the dynamically closed contact of the relay is connected with a relay coil. The agricultural machinery and implement anti-theft circuit overcomes defects that anti-theft devices of agricultural machinery and implements in the prior art are various in types, and the cost is high. The agricultural machinery and implement anti-theft alarm circuit provided by the utility model is convenient to use, reliable and low in cost.
Description
Technical field
The utility model relates to a kind of anti-theft warning circuit, especially a kind of agricultural machinery and implement anti-theft warning circuit.
Background technology
In recent years, many peasant's familys had all been purchased hand tractor and various agricultural machinery and implement, and evening, great majority were parked in the garden, and the stolen phenomenon of agricultural machinery and implement and accessory happens occasionally.At this kind phenomenon, need to install burglar alarm; Existing burglar alarm kind is a lot, and the mechanical electronic type that also has is arranged.Burglar alarm for electronic type mainly contains microwave and infrared warning device, wherein microwave alarm is subject to electromagnetic interference (EMI), cause wrong report easily, and its function singleness of existing infrared warning device, result of use is bad and cost is higher, for the economic capability in rural area additionally this expense bear.
The utility model content
Technical problem to be solved in the utility model is many at agricultural machinery and implement alarm kind in the prior art, the cost height causes peasant household to be reluctant to install alarm, makes the defective of antitheft difficulty of farm implements, a kind of agricultural machinery and implement anti-theft warning circuit is provided, easy to use, reliable and cost is lower.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of agricultural machinery and implement anti-theft warning circuit, comprise the power supply, gauge tap, mercury cut-off, PWM controller, relay, relay moving together contact, Music Clip, the loudspeaker that connect successively, described power supply links to each other with PWM controller, relay respectively by gauge tap, described Music Clip, loudspeaker link to each other with relay moving together contact one end respectively, and the other end of relay moving together contact links to each other with described relay coil.
The course of work of the technical solution of the utility model: alarm circuit stood alert after gauge tap was closed.When the people stole car, handlebar lifted, and mercury cut-off is closure state, and the PWM controller gets electric work, stopped newspaper after mercury cut-off opened circuit back one minute, or turn-offed gauge tap and stop newspaper; Behind PWM controller output pulse width modulation level, relay adhesive, its moving together contact closure, the high pitch loudspeaker that Music Clip got electric work and outputed signal to this moment, loudspeaker sends strong public security alarm sound equipment immediately, reminds master alarm, frightens the thief simultaneously away; When circuit was installed, the gauge tap ratio was placed on concealed location.
Adopt the utility model that following technique effect is arranged: 1, simple in structure, the cost of chip is lower, can satisfy the antitheft requirement of the various farm implements machines in rural area; 2, the gauge tap of the setting in the circuit can because of mercury cut-off be touched unintentionally cause circuit wrong report after, cut off circuit timely, alarm stops newspaper.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of agricultural machinery and implement anti-theft warning circuit, comprise the power supply, gauge tap SA, mercury cut-off SY, PWM controller, relay K 1, the moving together contact K1-1 of relay K 1, Music Clip, the loudspeaker B that connect successively, described power supply links to each other with PWM controller, relay K 1 respectively by gauge tap SA, described Music Clip, loudspeaker B link to each other with moving together contact K1-1 one end of relay K 1 respectively, and the other end of the moving together contact K1-1 of relay K 1 links to each other with the coil of described relay K 1.
PWM controller in the utility model adopts the single-chip microcomputer of 89C51 model, and Music Clip adopts music integrated block IC, and model is CW93561; Mercury cut-off is selected unidirectional capable type, highly sensitive for use.
Above-described only is preferred implementation of the present utility model, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement.These also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
