Description

The connecting device of car alarm and mobile phone

Affiliated technical field

The utility model relates to a kind of auto electronic anti-joyride device, and it can monitor situation in the car, relies on the cell phone network overlay area, transmits the car alarm of alarm message and the connecting device of mobile phone.

Background technology

Present known GSM (CDMA) car alarm is by mobile unit, public network equipment (communication partly), the control or connect the control center and form of receiving a crime report.It has solved control of automobile remote-control Car Burglar Alarm and the near problem of passback distance substantially, rely on cell phone network to transmit alarm message, there is not distance limit, in the GSM network's coverage area, all can and show vehicle state information by mobile phone control, it has many advantages and function, but can not get widespread use owing to cost is high.

Summary of the invention

In order to overcome existing GSM (CDMA) car alarm, problem that can not popularization and application, it is practical novel provide a kind of simple can popularization and application car alarm and connecting device of mobile phone.

The technical scheme that the utility model adopted has 2 kinds, and the 1st kind is: form ball bearing made using with two relays and two diodes between car alarm and mobile phone.Specifically as shown in Figure 1: first relay K 1 contact is normally closed, and often open second relay K 2 contact.Their contact series connection, series connected two ends are in parallel with redial key or the speed group key of mobile phone S, coil one end of relay K 1 is connected with power supply B, the other end by with two diode connected in parallel D1, D2 respectively with Car Burglar Alarm in the mouth of locking of U seven Darlington driving circuits be connected with the mouth of unblanking.Diode D1, D2 reversing sense voltage isolation are not disturbed the electric signal of locking and unblanking mutually.The coil of relay K 2, an end is connected with power supply B, and the other end is connected with the terminal of U seven Darlington driving circuits control alarm speaker in the Car Burglar Alarm.Under the situation that Car Burglar Alarm is set up defences,, put through alarm call when being subjected to triggering the button that the Car Burglar Alarm alarm speaker mouth output low level relay K 2 action closings of contact are connected mobile phone S.Set up defences on by remote controller or release when removing key, the lock end or the instantaneous low level of end output of unblanking of Car Burglar Alarm, relay K 1 action contact open, the alarm speaker control end of Car Burglar Alarm is exported instantaneous low level simultaneously, relay K 2 action contactings have been prevented by alarm speaker and have been sounded and the alert phone of misconnection circular.

The 2nd kind is: form ball bearing made using with two relays and two diodes equally between car alarm and mobile phone, specifically as shown in Figure 3 among the embodiment 2 first relay K 1 contact normally closed, its contact one end is connected with coil one end of second relay K 2, the contact other end is connected with U seven Darlington driving circuits control alarm speaker mouth on the Car Burglar Alarm mainboard, coil one end of relay K 2 is connected with normal open electricity B, coil one end of first relay K 1 passes through with two diode connected in parallel D1, the mouth of locking on D2 and the Car Burglar Alarm mainboard in the U seven Darlington driving circuits is connected with the mouth of unblanking, the other end of coil is connected with power supply, its contact of relay K 2 dial key with mobile phone S speed or the replay key in parallel.When by setting up defences during key on the remote controller, the mouth of locking of the central door lock control end of Car Burglar Alarm is by diode D1 output moment low level, and relay K 1 contact open has been controlled the coil of relay K 2, cause relay K 2 to be failure to actuate, accomplish when setting up defences, to disconnect mobile phone S.During releasing key on pressing remote controller, the mouth of unblanking of the central door lock control end of Car Burglar Alarm is by diode D2 output moment low level, relay K 1 contact open has been controlled the coil of relay K 2, cause relay K 2 to be failure to actuate, accomplish when removing key, to disconnect mobile phone S by remote controller, under the situation that Car Burglar Alarm is set up defences, Car Burglar Alarm alarm speaker mouth output low level when being subjected to triggering makes relay K 2 contacting mobile phone S.

The beneficial effects of the utility model are, automobile can popularization and application, only adopts two diodes and two relays, and is simple in structure.

The specific embodiment

In embodiment illustrated in fig. 21, the normally closed K1 of relay contact, often open K2 with relay contact, their series connection two ends, contact are in parallel with mobile phone S speed group key or redial key, the coil of relay K 1 is in parallel with capacitor C 1, one end of coil and normal open electricity B is connected the other end, is connected with the mouth of unblanking by the mouth of locking of the central controlled lock among the driving circuit U on diode D1, D2 and the Car Burglar Alarm mainboard.The coil of relay K 2 is in parallel with capacitor C 2, one end of coil is connected with normal open electricity B, control alarm speaker mouth is connected among the driving circuit U on the other end and the Car Burglar Alarm mainboard, when by setting up defences during key on the remote controller, the mouth of locking among the driving circuit U is by diode D1, output moment low level relay K1 contact open, and make capacitor C 1 obtain charging, middle control alarm speaker mouth among the while driving circuit U, output moment low level relay K2 contacting, and make capacitor C 2 obtain charging, after alarm speaker rings one, cond C1, C2 discharges and makes relay K 1, the contact of K2 kept for one logical one disconnected state a period of time, disconnected mobile phone S when accomplishing to set up defences.During releasing key on pressing remote controller, the mouth of unblanking among the driving circuit U is by diode D2 output moment low level relay K1 contact open, and make capacitor C 1 obtain charging, middle control alarm speaker mouth twice moment low level relay K2 contacting among the driving circuit U is twice simultaneously, and make capacitor C 2 obtain charging, after alarm speaker rings two, because cond C1, capacitor C 1 capacitance is greater than capacitor C 2 capacitances 1/2 among the C2, cond C1, C2 discharges and makes relay K 1 contact parting time be longer than 2 dwell times of relay K slightly, has accomplished to disconnect when releasing is antitheft mobile phone S.Under the situation that Car Burglar Alarm is set up defences, be subjected to triggering driving circuit U alarm speaker mouth output low level, make relay K 2 contacting mobile phones.

Be connected with coil one end that K2 often left by relay contact at its contact of normally closed K1,2 repeat circuit contacts embodiment illustrated in fig. 3 one end, control alarm speaker mouth is connected among the driving circuit U on the contact other end and the Car Burglar Alarm mainboard, coil one end of relay K 1 and normal open electricity B is connected, and the other end is connected with the mouth of unblanking by the mouth of locking among the driving circuit U on diode D1, D2 and the Car Burglar Alarm mainboard.Its contact of relay K 2 dial key with mobile phone S speed or the replay key in parallel, its coil one end is connected with the contact of relay K 1, the other end is connected with the electric B of normal open.When by setting up defences during key on the remote controller, the mouth of locking of the central door lock control end among the driving circuit U is by diode D1 output moment low level, and relay K 1 contact open has been controlled the coil of relay K 2, cause relay K 2 to be failure to actuate, accomplish when setting up defences, to disconnect mobile phone S.During releasing key on pressing remote controller, the mouth of unblanking of the central door lock control end among the driving circuit U is by diode D2 output moment low level, relay K 1 contact open, controlled the coil of relay K 2, cause relay K 2 to be failure to actuate, accomplish when removing key, to disconnect mobile phone S, under the situation that Car Burglar Alarm is set up defences by remote controller, driving circuit U alarm speaker output low level when being subjected to triggering makes relay K 2 contacting mobile phone S.
