Abstract

The utility model relates to a multi-trigger monitoring device, which comprises a switch circuit, a trigger circuit and a wireless alarm module circuit. Output signals of the trigger circuit are transmitted to the trigger circuit, and output signals of the trigger circuit are transmitted to the wireless alarm module circuit. When the switch circuit of the multi-trigger monitoring device is triggered to be connected, the wireless module emits alarm information to a reception module to trigger wireless emission alarm via one key; and the multi-trigger monitoring device can be widely used for anti-theft monitoring for objects such as motorcycles and household electrical appliances.

Description

A kind of many flip-over types supervising device

Technical field

The utility model relates to a kind of supervising device, particularly be a kind of many flip-over types supervising device.

Background technology

The stolen of article such as automobile, motorcycle, household electrical appliance happen occasionally, and mainly are based on onsite alarming, and are if the next door does not have personnel to guard, just stolen easily.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of many flip-over types supervising device is provided.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of many flip-over types supervising device, comprise on-off circuit, trigger circuit and radio alarming modular circuit, the output signal of described on-off circuit is transferred to trigger circuit, and the output signal of described trigger circuit is sent to the radio alarming modular circuit.

Described on-off circuit is contained in the steel ball G of monitoring on the thing as switch by being parallel to ground, the B end of this steel ball G is connected to the base stage of transistor VT1 through resistance R 4, the other end A end of steel ball G is connected to the collector of transistor VT1, and the emitter of described transistor VT1 and base stage are connected with direct earth capacitance C1.

Described radio alarming modular circuit adopts FDD-5 transmitter module IC2.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: when on-off circuit of the present utility model is triggered conducting, send warning message by wireless module to receiver module, realize that a key triggers the wireless transmit warning function, is widely used in the anti-thefting monitoring of article such as motorcycle, household electrical appliance.

Description of drawings

Fig. 1 is frame assumption diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a kind of many flip-over types supervising device of the present utility model, comprise on-off circuit 1, trigger circuit 2 and radio alarming modular circuit 3, the output signal of described on-off circuit 1 is transferred to trigger circuit 2, and the output signal of described trigger circuit 2 is sent to radio alarming modular circuit 3.

Described on-off circuit 1 is contained in steel ball G on the monitoring thing as switch by being parallel to ground, the B end of this steel ball G is connected to the base stage of transistor VT1 through resistance R 4, the other end A end of steel ball G is connected to the collector of transistor VT1, the emitter of described transistor VT1 and base stage are connected with direct earth capacitance C1, behind the power connection, electric current charges to foot to capacitor C 1 through resistance R 3 is very fast, and trigger module IC1 is in cleared condition.Touch when being monitored object as the people, be parallel to ground and be contained in steel ball G on the car body just to rolling on one side, A, B are connected in short-term, when A, B connect in short-term, make transistor VT1 that conducting in short-term also takes place.Electric charge on the capacitor C 2 discharges through resistance R 2, transistor VT1 by diode VD1.High level cancellation on the R end of trigger module IC1 begins counting.Capacitor C 2 begins charging again simultaneously, reaches logic high, trigger module IC1 zero clearing through 4s (this time is adjustable) R end approximately.

Because stealer meeting mobile object, steel ball G is rolled, soon will make A, 3 times (being that trigger module IC1 is triggered 3 times) connected at the B two ends, at this moment the Q9 of trigger module IC1 end is exported high level, through resistance R 6 current limlitings, make triode VT2 conducting, be input to the 2nd pin of FDD-5 transmitter module IC2, and deliver to the 3rd pin of FDD-5 transmitter module IC2, be modulation signal input end CP, the high-frequency signal of emission modulated that the antenna TX that FDD-5 transmitter module IC2 output terminal connects namely externally launches modulated frequency electromagnetic waves, send warning message to the wireless receiving alarm module, be widely used in motorcycle, article such as household electrical appliance carry out anti-thefting monitoring.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
