Principle of work of the present utility model is as follows: if owner wants to understand vehicle condition, with mobile phone or any phone, put through this wireless mobile monitoring and monitor the mobile portable phone circuit of annunciator, mobile phone circuit in the vehicle produces ringdown at this moment, ringdown interface L1, L2 insert the two ends of cell phone incoming call ringing loudspeaker in the circuit, and ringdown is through full-bridge rectifier (VD ₁) rectification, the output dc control signal is through resistance (R ₁) control transistor (VT ₁) conducting.Each ringing signal, transistor (VT ₁) conducting once.Schmidt trigger (IC1-1A) upset once makes by resistance (R ₆), electric capacity (C ₂) 4 seconds high potentials of time delay circuit time-delay of constituting, make smith trigger (ICA-2B, ICA3C) upset, output high level, diode (VD ₂) end, the multi-vibrator work of forming by Schmidt trigger (ICA-4D, ICA-5E) and peripheral component 4 seconds, and produce the oscillator signal of 1Hz/S, drive relay (K ₁) adhesive, discharge 4 times, as relay (K ₁) when moving, its contact (K _1-1) trigger the mobile phone circuit receiver-lifting key, mobile phone is connected automatically, wait for the reception of control command.

If a situation arises for vehicle, when the people touched your vehicle or enter the monitoring place, warning sensor (SB) closure made one-way SCR (VS) conducting, and power supply is through one-way SCR (VS), relay (K ₂) normally closed contact (K _2-2) to the multi-resonant oscillating circuit power supply of forming by time base circuit (ICG), make circuit working, its 3rd pin output 100S high level, the low level impulse singla of 40S, and circulation.During high level output, through electric capacity (C ₂₅), resistance (R ₃₀) make transistor (VT ₁) saturation conduction, ON time is about 1-2 second, makes relay (K ₁) adhesive, discharge 4 times, realize dialing automatically.Report to the police because this is a dangerous situation, thus must notify owner, just in case owner do not receive, then this annunciator can be after 2 minutes repetition of alarms once more, receive up to owner, and press " 0 " pressure stop signal, make relay (K ₂) normally closed contact (K _2-2) disconnect, cut off the power supply of multi-resonant oscillating circuit, stop to send signal.

If desired vehicle is controlled, only need press mobile phone " 0 " key continuously more than 6 times, just can hear transmit in the receiver that vehicle sends finish Tip Sound " the ticking---" sound of closing vehicle, control is described effectively, you observe conditions at the vehicle that should arrive in the very nick of time.After removing warning, you can reenter monitor state by control vehicle, and recover start, as long as press mobile phone " 1 " key more continuously more than 6 times, just can hear and transmit Tip Sound " the ticking---" sound of finishing the recovery vehicle that vehicle sends in the receiver, illustrate that control effectively.

The concrete working process of instruction control is as follows:

Shutdown control: in " hands-free " socket in the audio signal input end access vehicle mobile phone circuit, and insert the microphone circuit.When sending instruction, owner comes, double frequency multitone audio decoder (ICF) the 9th pin input control sound signal, through decoding, if " 0 " instruction, explanation is the requirement shut-off circuit, double frequency multitone audio decoder (ICF) the 12nd pin output high level, Schmidt trigger (ICB-1A) output low level.When the button end first time, double frequency multitone audio decoder (ICF) the 12nd pin output high-low level, Schmidt trigger (ICB-1A) output high level, high level control counter (ICD) counting of this positive rise once, the 6th button up to owner finishes the output pin (Q of counting machine (ICD) ₅) the output high level.

Output pin (Q when counting machine (ICD) ₅) when exporting high level, one road signal is by electric capacity (C ₉), jumper terminal (J _1-1), the 1st, 2 bipod closures of control figure switch circuit (ICG-1A), high level control counter (ICE) the 15th pin preset end (RST) that the 2nd pin produces resets, and makes the natural return-to-zero of counting machine (ICE), waits for the arrival of dependent instruction.

Output pin (the Q of counting machine (ICD) ₅) another road of high level control Schmidt trigger (ICA-6F) upset, output low level makes transistor (VT ₃) conducting, relay (K ₂) adhesive, its contact (K _2-1) closure, close the ignition system or the relevant warning of control of vehicle and force to report to the police.

Simultaneously, the output pin (Q of counting machine (ICD) ₅) high level by electric capacity (C ₁₀), resistance (R ₁₄) charge, make Schmidt trigger (ICB-3C, ICB-4D) upset, output high level, diode (VD ₆) end, the audio frequency oscillator work of being made up of Schmidt trigger (ICB-5E, ICB-6F) 2 seconds is through electric capacity (C ₁₂) make buzzer call, and send into " the microphone input " mouthful of mobile phone circuit by the VP contact, send the sound signal of control command success to owner.

Start control: when owner sends the instruction of " 1 " starting-up signal, double frequency multitone audio decoder (ICF) the 11st pin output high level, Schmidt trigger (ICB-2B) output low level.When the button end first time, double frequency multitone audio decoder (ICF) the 11st pin output high-low level, Schmidt trigger (ICB-2B) output high level, high level control counter (ICE) counting of this positive rise once, the 6th button up to owner finishes the 1st pin (Q of counting machine (ICE) ₅) the output high level, its controllable function is as follows:

The 1st pin (Q of counting machine (ICE) ₅) the output high level, through electric capacity (C ₁₄) control figure switch circuit (ICG-4D) the 8th, 9 bipod closures, high level control counter (ICD) the 15th pin preset end RST that the 9th pin produces resets, make the natural return-to-zero of counting machine (ICD), remove the shutdown control of last time, and wait for the arrival of the shutdown command of next time.Simultaneously, the 1st pin (Q of counting machine (ICE) ₅) output high level, through electric capacity (C ₁₅), resistance (R ₂₃) charge, make the audio frequency oscillator work 2 seconds that Schmidt trigger (ICC-5E, ICC-6F) forms, through electric capacity (C ₂₀) and by buzzer phone (VP) contact send into mobile phone circuit " microphone input " mouth, to the sound signal that owner sends the control command success, finish control.

It is transmission medium owing to having adopted the mobile phone control signal that wireless mobile monitoring provided by the utility model is monitored annunciator, it is far and near that it can be regardless of distance, your vehicle was monitored in 24 hours round-the-clockly, when dangerous situation occurring, can report to the police from predefined master cellular phone of trend or phone number dial, owner can monitor annunciator to wireless mobile monitoring at any time and send out control command, understands the security situation of vehicle or makes it force to stop.Control very reliable.
