Abstract
The utility model relates to an anti-theft alarm of an accumulator. A loudspeaker of the anti-theft alarm of an accumulator is directly connected with a power amplifying integrated circuit; a voice integrated circuit is connected with the power amplifying integrated circuit; a loop of the anti-theft alarm of an accumulator is connected with a direct current power supply in series, and simultaneous, the loop of the anti-theft alarm of an accumulator is connected with an accumulator, a relay which is connected with a testing push-button switch in series and a linked switch, wherein, the relay and the testing push-button switch are respectively in a normally opened state and a normally closed state under the normal state of the accumulator. When the anti-theft alarm of an accumulator of the utility model is adopted, the utility model has the advantages of simple structure, convenient use, convenient installation, sensitive response, little error rate and wide ranges of application; the utility model is quite an ideal anti-theft alarm of an accumulator.
Description
The utility model relates to a kind of electronic anti-theft alarm material, mainly is meant a kind of accumulator burglar alarm that utilizes audio alert.
Present various burglar alarm assortment class is a lot, but the burglar alarm that is exclusively used in the accumulator on motor vehicle or other plant equipment is then for blank, and along with the continuous development of China's industry especially auto industry, the application of accumulator is also more and more, because the volume of accumulator own is little, in light weight, applied widely in addition, therefore accumulator often more easily becomes stolen object, but owing to still do not have at present a kind ofly can prevent the device that accumulator is stolen effectively, make the stolen phenomenon of accumulator on motor vehicle or other plant equipment happen occasionally, bring many inconvenience to users.
The purpose of this utility model just is to provide a kind of novel accumulator burglar alarm, to be cut off (accumulator is stolen) warning structure by its unique phonetic warning system and sensitive accumulator electric-quantity wretched insufficiency or accumulator loop, not only overcome the deficiencies in the prior art effectively, and have simple in structure, easy to install and use, be quick on the draw, advantage that error rate is little and applied widely.
The purpose of this utility model realizes in the following manner: a kind of accumulator burglar alarm, mainly be by shell, circuit board, loudspeaker, speech IC, relay and interlock circuit are formed, it is characterized in that its loudspeaker directly links to each other with power amplification circuit, speech IC links to each other with power amplification circuit, on its loop, be in series with direct supply, relay and linked switch, above-mentioned relay and linked switch are connected with accumulator and test peace rotary switch simultaneously, and its repeat circuit and test peace rotary switch are in normal off and normally off respectively under the normal state of accumulator.
Adopt accumulator burglar alarm of the present utility model, owing to adopted unique phonetic warning system and sensitive accumulator electric-quantity wretched insufficiency or accumulator loop to be cut off (accumulator is stolen) warning structure, the deficiencies in the prior art have not only been overcome effectively, and have simple in structure, easy to install and use, be quick on the draw, advantage that error rate is little and applied widely, be a kind of very desirable accumulator burglar alarm.
Description of drawings:
Fig. 1 is a kind of example structure synoptic diagram of the present utility model;
Fig. 2 is a wiring diagram of the present utility model.
Wherein: 1-housing, 2-wiring board, 3-loudspeaker, 4-power amplification circuit, 5-speech IC, 5-linked switch, 7-relay, 8-accumulator, 9-direct supply, 10-test peace rotary switch.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in drawings, accumulator burglar alarm of the present utility model, mainly be by shell (1), circuit board (2), loudspeaker (3), speech IC (5), relay (7) and interlock circuit are formed, it is characterized in that above-mentioned loudspeaker (3) directly links to each other with power amplification circuit (4), speech IC (5) links to each other with power amplification circuit (4), on its loop, be in series with direct supply (9), relay (7) and linked switch (6), above-mentioned relay (7) and linked switch (6) are connected with accumulator (8) and test peace rotary switch (10) simultaneously, and its repeat circuit and test peace rotary switch are in normal off and normally off respectively under the normal state of accumulator.
In an embodiment, speech IC (5) adopts KD-9561 (or KD-9561B) and TWH8751 respectively, the common four pin normally closed relays that relay then adopts automobile to use with power amplification circuit (4).During work, after connecting accumulator, connect linked switch, this moment, relay was in the normal off position under the electric energy effect of accumulator, warning circuit is not worked, and when accumulator electric-quantity wretched insufficiency or accumulator loop were cut off (accumulator is stolen), relay was with the warning circuit closure, make warning circuit work, loudspeaker sends chimes of doom.The existence of test peace rotary switch can determine easily whether whole accumulator burglar alarm installs and whether normally work.
Claims (2)
1, a kind of accumulator burglar alarm, it mainly is made up of shell (1), circuit board (2), loudspeaker (3), speech IC (5), relay (7) and interlock circuit, it is characterized in that above-mentioned loudspeaker (3) directly links to each other with power amplification circuit (4), speech IC (5) links to each other with power amplification circuit (4), be in series with direct supply (9), relay (7) and linked switch (6) on its loop, this relay (7) and linked switch (6) are connected with accumulator (8) and test peace rotary switch (10) simultaneously.
2, accumulator burglar alarm according to claim 1 is characterized in that its repeat circuit (7) and test peace rotary switch (10) are in normal off and normally off respectively under accumulator (8) normal condition.
