Description

Multifunctional alarm with various probes mounted

A kind of multifunction alarm device of configurable variety classes probe relates to a kind of warning device of electronic technology.

Multifunction alarm device of the prior art, generally all has a fixing sniffer, fixing probe for example, because this fixing sniffer is difficult to expand, change on structure type, therefore can only realize the multi-functional warning of subrange, and can't realize omnibearing multi-functional warning, this has just limited the alarm range of alarm.

The purpose of this utility model is to develop a kind of multi-functional warning that can dispose the polytype probe, by the requirement of selecting conducting to trigger, select different types of probe, select different sources of sound, select different control modes, be implemented in the multifunction alarm device in the different environment.

Technical solution of the present utility model is: the multifunction alarm device of configurable variety classes probe is made of power circuit, conducting trigger circuit, sounding circuit, power amplifier, control circuit, probe.

Below in conjunction with description of drawings the utility model content.

Fig. 1 electric theory diagram of the present utility model

Fig. 2, Fig. 3, Fig. 4 the utility model circuit diagram

The structure principle chart of Fig. 5 several probes of the present utility model

With reference to Fig. 1, the utility model comprises following several part: power supply (1), conducting circuits for triggering (2), sounding circuit (3), power amplifier (4), control circuit (5), probe (6).

Power supply (1) is supplied with whole internal circuit power supply, adopt external power source and the direct-connected method of internal cell power supply, but both external power source work, but also internal electric source powered operation, also powered operation simultaneously, 4.5-12VDC in the supply voltage permissible value scope.

With reference to Fig. 2, conducting circuits for triggering (2) are by triode BG1, BG2, BG3, single face controllable silicon diode BT1, BT2, and resistance R 1, R2, capacitor C 1, C2, jack XS1, toggle switch K1 forms. Wherein jack XS1 directly links to each other with probe (6), when the equivalent resistance of probe (6) changes to a certain value, Conducting circuits for triggering (2) turn on and off the electric current of sounding circuit (3), power amplifier (4), control circuit (5), wherein, four kinds of conducting triggering modes by toggle switch K1 control conducting circuits for triggering (2), can adapt to the control requirement under all kinds probe and the various condition, explain detailedly below:

Mode 1, when vigorous moving K switch 1 pushes at 1, be the break trigger mode, when this device is ready, equivalent resistance is raised to certain value in a flash by low resistance or for above freezing if pop one's head in this moment, triode BG1 conducting, and controllable silicon diode BT1 is triggered, conducting trigger circuit this moment (2) are in on-state, and output current is to sounding circuit (3), power amplifier (4) and control circuit (5).

Mode 2 when toggle switch K1 pushes at 2, is direct conduction mode, and the two-stage short circuit if pop one's head in this moment is just the electric current of the probe of then flowing through directly outputs to sounding circuit (3), power amplifier (4) and control circuit (5).

Mode 3, when toggle switch K1 pushes at 3, be direct triggering mode, after this device is ready, equivalent resistance becomes low resistance state in a flash by high-impedance state if pop one's head in this moment, controllable silicon diode BT2 is triggered, and transmits electric current to sounding circuit (3), power amplifier (4) and control circuit (5).

Mode 4, when toggle switch K1 pushes at 4, then conducting trigger circuit (2) are for disconnecting conduction mode, after this device is ready, when equivalent resistance became high-impedance state by low resistance state if pop one's head in this moment, the base current of BG2 was by the negative pole of R2 to power supply, because the complex pipe enlargement factor that BG2 and BG3 form is very big, therefore BG3 saturation conduction immediately, output current is to sounding circuit (2), power amplifier (4) and control circuit (5).

Sounding circuit (3) is by toggle switch K2, music integrated block IC 1(KD-9561), IC2(KD-5601, KD-56010, KD-9300 series, KD-154B, KD-253 or KD-9013), capacitor C 3, C5, resistance R 3, R4, R5, R6, R7, discharge diode D2, stabilivolt W1 forms, its function is after receiving the electric current of conducting trigger circuit (2) output, sounding circuit (3) startup work, and output source of sound current signal is to power amplifier (4), the wherein selection of toggle switch K2 control source of sound, when toggle switch K2 1 the time, if have electric current to import then IC2 is triggered, K2 dials 2,3,4 o'clock, IC1 is triggered, and selects different interior storage sources of sound.

Sounding circuit (3) also has a kind of design proposal as shown in Figure 3, take four music-integrating blocks, select source of sound by K2 control, wherein IC4, IC5, IC6, IC7(KD-560, KD5601, KD56010, KD-9300 series, KD-154B, KD-253 or KD-9013) be fixed on the integrated package socket, can select different music-integrating blocks easily like this, thereby realize the multi-sourceization of source of sound.

Power amplifier (4) is by operational amplifier IC3(power amplifier 386), capacitor C 4, C6, C7, C8, resistance R 8, loudspeaker form, its principle of work be the source of sound current signal of sounding circuit (3) output through the IC3 power amplification after, be transported to loudspeaker.

Control circuit (5) is made of relay KR, K switch 3, and when K3 was closed, control circuit was in running order, and crossing often opening of KR can external certain electrical equipment or be connected a plurality of alarms with normally closed contact, realizes that cascade reports to the police.

Control circuit (5) also has a secondary design proposal as shown in Figure 4, and wherein K3 is the fourth gear toggle switch, and one grade is the entire circuit outage, and second gear is sounding circuit (3) and power amplifier (4) energising, and third gear is the whole circuit energising, and fourth gear is for only enabling control circuit.

Probe (6) adopts plug in construction directly to link to each other with conducting trigger circuit (2), and it is by the wiring sensitive element, and sensitive element encapsulating housing and circuit board are formed or an above-mentioned part is formed.Actual probe (6) can be regarded a resistive element as, its resistance changes with the variation of external condition, thereby whether control conducting trigger circuit (2) are connected by conducting trigger circuit noted earlier (2), there are four kinds to connect triggering mode, can adapt to various types of probes, therefore the type selecting of this device probe is very extensive, roughly be divided into following three major types: the mechanical type probe, the sensitive element probe, coupling probe, example as shown in Figure 5, wherein a is the wiring probe, b, c is the switch probe, they belong to the mechanical type probe, d, e, f is light-operated probe, g, h is wet sense probe, and they belong to sensitive element probe, i, j, k is voltage or current probe, one-tenth coupling probe capable of being combined, Fig. 5 example is this sub-fraction of installing applicable probe, and other kinds type probe all can be complementary with this device, so this device has a tractor serves several purposes flexibly.

This device is easy to use flexibly, the different choice of three K switch 1, K2, K3, be not subjected to the restriction of sequencing, the various combination of probe, K switch 1, K2, K3, can adapt to warning and control requirement under the multiple condition, as can be used as wire break alarm, electricity-limiter, live wire detector, electronic door bell, car alarm, spill back driving warning safety, urine-wet alarm device etc., can be widely used in fields such as finance, military affairs, confidential, warehouse, family, be that a kind of function is many, modern design is taken precautions against comprehensive new product.
