Description
Technical field
The utility model relates to a kind of car alarm, specifically a kind of on-vehicle safety protection alarm.
Background technology
Along with the development of science and technology, the living standard of people improves constantly, automobile has progressed into a lot of family, but meanwhile, because the robbery case that automobile causes also increases gradually, especially the taxi of work at night, be easy to be kidnapped, in this case, the every act and every move of driver is all under the supervision of criminal, therefore very difficult mobile phone is reported to the police, property and the life security of driver can not get effective guarantee, or get into an accident at remote sites, driver cannot action on a large scale, therefore rescue time has seriously been delayed, car alarm is in the market arranged for burglar mostly, do not have initiatively to trigger and help driver to carry out the device of reporting to the police.
Utility model content
The purpose of this utility model is the on-vehicle safety protection alarm providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of on-vehicle safety protection alarm, comprises electrode slice A, resistance R2, electric capacity C3, chip IC 2 and relay J, the base stage of described electrode slice A connecting triode V1, the contact J-1 of the collector connection relay J of triode V1, power supply VCC, the pin 1 of chip IC 1, the pin 4 of chip IC 2 and the pin 8 of chip IC 2, the emitter contact resistance R2 of triode V1 and the negative electrode of diode D4, the anode of diode D4 connects electric capacity C3, switch S, relay J, the anode of diode D2, transmitting set W, minisize pick-up head P, the pin 4 of chip IC 1 and the pin 1 of chip IC 2, the other end of resistance R2 connects the other end of electric capacity C3 and the pin 3 of chip IC 1, the pin 2 contact resistance R3 of chip IC 1, the other end contact resistance R5 of resistance R3 and the other end of switch S, the other end of resistance R5 connects the pin 6 of chip IC 2, the pin 3 of chip IC 2 connects the anode of diode D3, the other end of the contact J-1 of relay J connects the other end of transmitting set W and the other end of minisize pick-up head P, the signal of described chip IC 1 is TWH8778, and the model of chip IC 2 is NE555.
As preferred version of the present utility model: described relay J is normally opened contact relay.
Compared with prior art, the beneficial effects of the utility model are: the utility model on-vehicle safety protection alarm circuit structure is simple, components and parts are few, there is touch mode alarm function, when running into emergency case or be held as a hostage, driver only need touch hidden electrode slice with hand will trigger alarm circuit, open camera record in-vehicle information by Control, and be sent to the mobile phone of public security organ and relatives by transmitting set, there is the advantage that good concealment, diverse in function, security protection are effective.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of on-vehicle safety protection alarm.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of on-vehicle safety protection alarm, comprises electrode slice A, resistance R2, electric capacity C3, chip IC 2 and relay J, the base stage of described electrode slice A connecting triode V1, the contact J-1 of the collector connection relay J of triode V1, power supply VCC, the pin 1 of chip IC 1, the pin 4 of chip IC 2 and the pin 8 of chip IC 2, the emitter contact resistance R2 of triode V1 and the negative electrode of diode D4, the anode of diode D4 connects electric capacity C3, switch S, relay J, the anode of diode D2, transmitting set W, minisize pick-up head P, the pin 4 of chip IC 1 and the pin 1 of chip IC 2, the other end of resistance R2 connects the other end of electric capacity C3 and the pin 3 of chip IC 1, the pin 2 contact resistance R3 of chip IC 1, the other end contact resistance R5 of resistance R3 and the other end of switch S, the other end of resistance R5 connects the pin 6 of chip IC 2, the pin 3 of chip IC 2 connects the anode of diode D3, the other end of the contact J-1 of relay J connects the other end of transmitting set W and the other end of minisize pick-up head P, the signal of described chip IC 1 is TWH8778, and the model of chip IC 2 is NE555.
Relay J is normally opened contact relay.
Principle of work of the present utility model is: electrode slice A is arranged on place that is hidden in car and that not easily touch at ordinary times, when running into emergency case or be held as a hostage, driver only need touch hidden electrode slice with hand, electrode slice A senses human-induced signal and converts electric signal to and exports, be equivalent to provide a signal to triode V1 base stage, after Current amplifier, deliver to TWH8778 high-power driving switch integrated circuit, 6 pin of NE555 are made to be low level, thus make its 3 pin be high level, relay J conducting, its normally opened contact J-1 adhesive, the work all switched on of transmitting set and minisize pick-up head, if Touching electrode lost efficacy when using, Closing Switch S can also be passed through, 6 pin of chip IC 2 are forced to drag down, and then make its 3 pin defeated place high level, same meeting trigger relay, reach the object of open wireless transmitter and minisize pick-up head.Circuit structure is simple, components and parts are few, there is touch mode alarm function, when running into emergency case or be held as a hostage, driver only need touch hidden electrode slice with hand will trigger alarm circuit, camera record in-vehicle information is opened by Control, and the mobile phone of public security organ and relatives is sent to by transmitting set, there is the advantage that good concealment, diverse in function, security protection are effective.
