Brief description of the drawings
Fig. 1 is electrical schematic diagram of the present utility model;
Wherein: 1 is alarming horm, 2 is alarm control circuit, and 3 is firing circuit control relay, and 4 is reed switch, and 51 ~ 54 is door lamp switch, and 6 is boot light switch, and 7 is strong magnets; A is high-tension coil, and R is adjustable resistance, and C is electric capacity, and T is aerotron, and J is alarm control relay.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of alarms and security systems for automobiles, comprises vehicle-mounted 12V power supply, warning and network type electron system; Vehicle-mounted 12V power supply is used to warning and network type electron system that power supply is provided; warning for sending warning in the time that arrangements for automotive doors or boot are opened; network type electron system, for controlling connection and the shutoff of ignition lock and power supply, effectively protects automobile normally to start.
Described warning comprises the alarm control circuit 2 and the trigger switch that are connected in series between vehicle-mounted 12V power supply and automobile shell ground, and trigger switch comprises the door lamp switch 51 ~ 54 and the boot light switch 6 that are arranged in parallel.Described warning also comprises the alarming horm 1 being connected in series between vehicle-mounted 12V power supply and automobile shell ground, and described alarming horm is by alarm control circuit control action.
Described alarm control circuit 2 comprises adjustable resistance R, capacitor C, aerotron T and alarm control relay J, described adjustable resistance is connected with capacitances in series, the base stage of aerotron is connected on the wire between adjustable resistance and electric capacity, the collecting electrode of aerotron connects vehicle-mounted 12V power supply, and the emitter of aerotron connects the ungrounded end of trigger switch; The coil of described alarm control relay is connected in series between transistor collector and vehicle-mounted 12V power supply, and the open contact of alarm control relay is connected in series between vehicle-mounted 12V power supply and alarming horm.
Described network type electron system comprises and is connected in series firing circuit control relay 3 and reed switch 4 between vehicle-mounted 12V power supply and automobile shell ground, and described reed switch is controlled conducting and shutoff by strong magnets 7; The open contact of described firing circuit control relay is connected in series between vehicle-mounted 12V power supply and high-tension coil.
Level sensor (braking liquid, the refrigerant fluid etc.) principle of the yellow switch of tongue and automobile is identical, and tongue disconnects at ordinary times, in the time being subject to magnetic attraction, connects.The installation site of reed switch, more hidden better, because being is subject to attraction, can be installed on completely in instrument desk or other backplates (reed switch volume is very little), outside be can't see at all, only has car owner oneself to know.After getting on the bus, only magnet need be placed on to the position at reed switch place, under magnet suction, reed switch is connected, thereby switching on the ignition circuit just can normally start automobile; Once magnet is taken away, reed switch disconnects, and firing circuit is cut off, car just can't be beaten naturally, and car owner gets off and takes away magnet (magnet can be adsorbed on above key, or takes away, or be adsorbed on the automobile ornaments such as perfume bottle, more hidden more naturally better, independently determined by car owner completely).In the utility model, the position of reed switch only has car owner to know, has therefore effectively ensured the start-up safety energy of automobile.
In the utility model, between vehicle-mounted 12V power supply and the open contact of alarm control relay, be also connected in series with the normally closed contact of firing circuit control relay, for making warning close warning in the time normally starting.
As shown in Figure 1, its principle of work is as described below for electrical schematic diagram of the present utility model:
Before car owner gets off, the strong magnets matching with reed switch is taken away, confirmed that four car doors of automobile and boot are closed after intact to leave (can ring if any the alarming horm not shutting) always, vehicle enters anti-theft state.
If someone opens car door or boot now, door lamp switch or boot light switch 6 are connected, connect vehicle-mounted 12V power supply (delay time can be controlled by the numerical value ratio of adjusting electric capacity and adjustable resistance) through alarm control circuit time delay, the alarm control actuating of relay, the open contact closure of alarm control relay, connects alarming horm circuit; Meanwhile because the strong magnets on reed switch 4 sides is removed, reed switch disconnects, and firing circuit control relay coil is not worked, the normally closed contact closure of firing circuit control relay, electric current is given to alarming horm by contact, so alarming horm starts to report to the police.If now start car, because firing circuit control relay coil is not worked, open contact cannot be connected, and firing circuit is cut off, therefore can not car.
If nobody triggers the utility model, car owner gets on the bus and opens car door or open boot and also can connect alarming horm circuit, alarm control circuit can not connected alarming horm relay in delay time, as long as strong magnets is positioned over to reed switch side in delay time, make firing circuit control relay coil obtain electric starting working, the open contact closure of firing circuit control relay coil, normally closed contact is opened, alarming horm will disconnect with vehicle-mounted 12V power supply, cannot pipe, can not cause flase alarm.
For have drive recorder automobile, the lead-in wire of alarming horm can also be connected with drive recorder, can take burglar and steal process, to restrained by law in trigger alarm.Certainly,, the lead-in wire of alarming horm can also connect radio transmitting apparatus, sends alerting signal by radio transmitting apparatus to car owner's mobile phone, reminds car owner to process in time.
