I. Product Overview road transport vehicles GPS vehicle terminal, in line with vehicle traveling data recorder GB GB / T GBT19056-2003, and the Ministry of Transport JT / T 794-2011 "road transport vehicle satellite positioning system vehicle terminal technical requirements", JT / T808-2011 "road transport vehicle satellite positioning system vehicle terminal communication protocol and data format" standard. Vehicle operating parameters can be real-time recording, display and query. Vehicles and traffic management can provide real raw data to provide further protection for the security. Through a wireless data communication interface (GSM, GPRS, CDMA) and GPS interface, with the monitoring center system for data and mobile location positioning can meet various needs of users. This product can effectively record the driver's speeding and fatigue driving and other illegal driving behavior, thereby driving on company personnel to effectively monitor the quality of work, reduce accidents and improve vehicle operation level. So the use of this product and ancillary systems platform to improve the company's overall management level and efficiency, reduce operating costs, improve economic efficiency and competitiveness of enterprises; objective and comprehensive record of the vehicle when the accident occurred various states and drivers operational behavior for traffic analysis provides scientific basis to protect the legitimate interests of the parties accident, convenient traffic police enforcement and government regulators.
