AVL GPS GPRS слежения за автотранспортными средствами системы

GPS & GPRS Tracking system Main Functions 1. Real-time Positioning and Tracking Vehicle GPS terminal is available for submitting information including position according to preset time interval, designated oclock or distance interval. 2. Over Speed Alarm Over speed alarm data is submitted automatically when the vehicle drives in a speed exceeding the set limit. 3. Track Reappearance The driving data and position information of a vehicle for a period of time may be saved in the server of the data center for query and reappearance. Characteristics of automobile GPS terminal (advantages): l Small size: Difficult to find and easy to install,l Low power consumption: Nearly have no infection to the vehicle battery.l High integrity: Adopt ARM chip with superior processing, highly integrate with automobile recording instrument, use 128×64 LCD display screen of automobile recording instrument to display short message or GPS information.l Strong extendibility: Multi-reserved interface, selectable communication handle, display and camera.l Excellent Stability: Industrial grade of chip, professional anti-interference process, multilevel battery protection and reliable equipment operation Characteristics of monitoring center: l Excellent interface and convenient operation, l Efficient dispatching system and support of more online vehicle, l Two version of software(C/S and B/S version), especially B/S version of software is very convenient for customer to examine vehicle and check historical track. l Software interface of monitoring and control centre can be customized according to customers requirement and habit of usage.
