Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of Vehicular satellite locating terminal, it is characterized in that: comprise vehicle power, switching input module, central processing unit, GPRS module, GPS module, GPRS antenna, imaging device, output driver module and storer;
Vehicle power is connected with switching input module, central processing unit, GPRS module, GPS module, GPRS antenna and output driver module respectively; The input end of switching input module is connected with vehicle, and output terminal is connected with the input end of central processing unit; Storer is connected with central processing unit; The output terminal of central processing unit is connected with GPRS module is two-way; The output terminal of described GPRS module is connected with GPRS antenna with GPS module; Described output driver module is connected with GPRS module is two-way.
Vehicle power provides 24V power supply, and its output terminal can provide multichannel output through reduction voltage circuit and overvoltage crowbar, can be central processing unit 3.3V voltage is provided, and can be switching input module 5V voltage is provided.When the output end voltage of vehicle power is too high, will automatically cut off the output of output terminal, GPS terminal enters self-shield state, in order to avoid its each module damage being connected with central processing unit output; When the voltage of power supply recovers normal value, GPS terminal restarts work.Whether switching input module has the power supply signal processing of encoding to switch for vehicle machine signal, vehicle-locking signal and outside, then by central processing unit to the processing of decoding of this coding.
Its input end of analog input module is connected with the various sensor signal lines of vehicle, and through analog conversion circuit, converting the simulating signal collecting to digital signal that Central Asia processor can be identified, central processing unit is processed on request to the digital signal after changing.Central processing unit is the single-chip microcomputer of one 32, and its input results according to switching input module and analog input module is decoded, and controls its GPRS module and realizes wireless transmission; When GPRS module is received the order from background service system or Surveillance center, central processing unit responds to vehicle according to order simultaneously, and response results is uploaded to background service system or Surveillance center.GPRS module major function is the wireless receiving and dispatching passage of data, and the instruction sending according to its central processing unit sends information, the teledata receiving is sent to central processing unit simultaneously.
Storer is for storing dependent instruction, operational mode, controlled condition and Rule of judgment that every day, whether controlled condition was carried out.In addition, storer also can be used for the storage of data, is convenient to external device inquiry service data.The image that imaging device can extraction system photographs during operation, and can store the image in storer, also can be by image by being wirelessly transmitted to tele-control system.
Especially, in GPS terminal, be provided with threshold voltage circuit, GPS also carries can rechargeable battery, when external voltage during higher than a certain particular value of threshold voltage power supply to use outside Vehicular accumulator cell voltage be whole GPS terminal power supply, return terminal simultaneously and charge from charged pool; When external voltage during lower than this threshold voltage voltage module to switch to terminal be whole GPS terminal power supply from charged pool.When the supply voltage of power module during lower than a certain particular value of threshold voltage the output circuit of power module be cut off, GPS terminal enters the state of quitting work; When Power supply voltage during higher than this threshold value GPS terminal just can enter duty.Central processing unit inside is provided with watchdog module, and watchdog module is connected with the transceiver module of central processing unit inside, auto restore facility in the time of can preventing from guaranteeing the situations such as the race of processor generating program flies, deadlock.Transceiver module has reception and sends informational function.
