Double Technology Co., Ltd. of vehicle management scheduling system using global satellite positioning system (GPS) to locate the vehicle monitoring Beidou installation company, SMS channel and the voice channel to transmit location via GSM digital mobile telephone network (GSM) tracking information and conduct bilateral communication, the company's exploration vehicle can be regulated. The data acquisition, data communications, business processing functions to divide, the system is divided into the following three parts: Part 1 car terminal: Includes GPS receiver and corresponding antenna, GPRS / CDMA module, control unit, handle, display, alarm buttons. Responsible for receiving and return GPS positioning information, help and so on. 2. Wireless communications link: responsible for data transfer between the control center and the vehicle terminal, including the transmission of information VPS / automatic information and control center control directives. This part of GPRS / CDMA, local Beidou long GPRS / CDMA can cover, the system can be stable operation. 3. Monitoring Centre: Monitoring Center is the nerve center of the whole system, focus on achieving the vehicle tracking. ) Refrigerated vehicle GPS Which is better? At present, corporate customers for cold chain logistics company's expectations higher and higher truck examined Beidou, corresponding industry regulatory standards are more and more the process of globalization continues to accelerate, leading to cold chain logistics industry operating more and more complex. Cold chain freight network has rapidly expanded into a large-scale, highly specialized equipment, involving industry-wide, a large number of employees in the industry. China at this stage is also a lack of effective cold chain logistics management, the existing monitoring technology lag is the biggest bottleneck. The main crux of our techniques used are: manual measurement and paper records; no unified data system support; real-time, poor supervision disjointed; difficult to obtain evidence, can not determine liability; unable to warning, the loss rate is high and so on. Double electronic technology companies use GPS in developed based on years of successful experience in GPS vehicle scheduling logistics management information system, based on the actual cold chain logistics enterprise business process requirements Beidou company management, full integration of GPS industry level scheduling monitoring technology, design a set of cold-chain logistics for freight management and integration services business information system solutions. Double GPS positioning refrigerated vehicle GPS monitoring system specific functions: 1, overtime parking warning: stop the vehicle exceeds a predetermined alarm time, and generate reports; haul prevent damage caused by a timeout. 2. Illegal box alarm: If the vehicle is not transported at defined locations open cargo box that is the police. 3, Box temperature real-time monitoring, over hot spots and low point alarms. 4, cold storage, customers point settings: Customers can customize the labels on the map the location of the cold storage or customer locations. 5, group management: All vehicles may be grouped construction site management, yaw-alarm settings, alarm settings, etc. segment limit. 6, the number of flights out of the designated area of ??statistics and time statistics. Beidou Beidou company _ love _ Double Double electronics provided by the Zhengzhou Electronic Technology Co., Zhengzhou Double Electronic Technology Co. (www.zzgprs.com) strong, credible, in Zhengzhou of GPS systems and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Double electronic and you hand into the brilliant, for a better future!
