The application scope of all-round positioning terminal products basically covers all fields and industry application requirements in the current market application; (four band GSM / GPRS communication module, universal in the world) (85090018001900 frequency band)

The product not only inherits all the functions of the previous terminal products, but also makes more optimization and improvement on the basis of the previous products, so that its performance in quality stability and power consumption has been improved;

The integrated module is used in the all-round positioning terminal, which can realize the functions of calling, SMS, GPRS, etc. in one module, it has high integration and high reliability. TCP / IP protocol stack is complete, and wireless network communication is faster and more reliable. The 450 MAH high temperature polymer lithium battery was used, and the standby time of the device using battery power was more than 6 hours, and the charging speed was faster;

The ad analog data acquisition has been corrected by temperature drift, and the analog signal measurement is more accurate; the antenna is well matched and can be located in 20 seconds; the GPS fault automatic power-off reset function is added to solve the GPS / non positioning fault caused by the aging of the long-term live working circuit of the GPS bucket module;

The internal buffer is increased to 2048 points, and the GPRS disconnection compensation point is more complete; with 485 bus, the camera can be connected for image acquisition at the same time, the LED screen is connected to realize advertising, and the oil quantity sensor is connected to realize the oil quantity monitoring.
