GPRS, SMS dual channel, vehicle locator, vehicle satellite positioning terminal

Based on the latest international industrial-grade chip architecture products, dual-core structure, powerful functions;
? GPRS, SMS dual channel, TCP and UDP dual mode work;
? Satellite reflected wave positioning, base station assisted positioning, strong anti-blocking ability, reducing blind spots;
? Product three-proof design, 4-fold power protection, 4-level "watchdog";
? Low power consumption, power saving mode <15mA, built-in large-capacity backup battery;
? The working power supply voltage is up to 60V, which is more suitable for vehicles with poor working conditions in China;
? SIM card tamper-proof alarm function;
? Exquisite structure, the size is reduced to 72x55x24mm. The installation is very simple, just connect the power supply and antenna;
? The terminal can be upgraded remotely and maintenance is simple.
? Signal detection and control (6 signal sensors, 8 vehicle state detection, intelligent and forced fuel and electricity control.)
      6 signal sensors: emergency button, ignition input, custom positive 1 input, low battery detection, mainframe power failure by backup battery, battery removal detection. 8 vehicle status detections: ignition, self-defined positive 1 input, fuel and electricity, guards, low battery detection, mainframe power failure by backup battery, battery removal detection, vehicle speeding. Intelligent and forced fuel-off control: implement controllable fuel circuit control on the vehicle according to the vehicle's ignition status and driving speed status.
? Vehicle alarm function (6 signal sensors, 8 vehicle state detection, intelligent and forced fuel and electricity control.)
      15 types of alarms: emergency alarm, guard alarm, battery removal alarm, low battery alarm, no entry and cross-border alarm, no cross-border alarm, road detection deviation alarm, road detection overspeed alarm, road detection passing time limit alarm, road The detection passes the time lower limit alarm, overspeed alarm, low speed alarm, fatigue driving alarm, satellite signal receiver failure alarm, and self-defined positive 1 input to trigger the alarm.
      3 kinds of alarm methods (related to communication protocol): management center SMS alarm, GPRS alarm, mobile phone self-service alarm.
? Vehicle monitoring function
  Vehicle automatic monitoring function, 108 area settings, electronic fence function, GPS mileage statistics, blind spot reporting function, trajectory storage function, base station auxiliary positioning function.
? Road detection function
  8 road detection data, road detection calculation, road detection deviation alarm, road detection speeding alarm, entry/exit report, passing time upper/lower limit alarm, and station related control. The terminal supports 8 different road information data detection functions at the same time, and the line attributes include: overspeed threshold, yaw road width, and entry and exit detection on related lines.
? Multi-center, multi-channel
     With dual IP connection, you can send information to 2 different management center IPs, SMS main and auxiliary dual monitoring center numbers (related to the communication protocol). GPRS/SMS (command, data) are parallel at the same time, and the terminal supports both TCP and UDP methods.
? remote control
  Rich command set, various functions can be turned on/off through commands, various parameters can be set in the air, the host program supports remote download, users can complete the program update without going to the scene when updating online, which improves efficiency and saves time .
? Protective function
 (1) Power saving mode: After the vehicle is turned off, the working current of the terminal power saving mode is reduced to 15mA@12V.
 (2) Battery over-discharge protection function: when the battery voltage is too low (10.5V), switch to backup power supply.
 (3) Overvoltage protection: If the limit voltage (60V) is exceeded, the external circuit protection terminal will be cut off immediately.
