Integerated satellite postioning vehicle carried termianl

Abstract

The present invention relates to integrated satellite positioning vehicle carried terminal. The satellite positioning device has its antenna RF connected via signal sending serial port and signal receiving serial port of GPS module to the interface circuit, and CPU serial port to the interface circuit, so that the received positioning and state information transmitted to the CPU. The antenna RF is connected via signal sending serial port and signal receiving serial port of GPS module to RS232 interface circuit, and the P3.2 port of the CPU serial port is connected to corresponding ports of RS232 interface circuit, so as to exchange information with the movable short message center and complete the real-time monitoring of the controlled vehicle. The data port of the CPU is connected via latch to PROM and RAM to store program and data. The received satellite positioning data and vehicle state information is data converted into protocol format and fed back via GSM network to the center as short message.

Description

Technical field: [0001] The invention provides an integrated satellite positioning vehicle-mounted terminal, relates to a system for real-time monitoring of vehicle running conditions, and belongs to the technical field of vehicle monitoring devices. Background technique: [0002] It has become an existing technology to use satellite positioning system to monitor the driving state of the vehicle and carry out scientific management, but the existing terminal products are relatively large in size, which brings certain difficulties to the installation. Both the GPS module and the GSM module have their own circuit boards, which are connected to the main board by wires. The interface circuits of different accessories are different, and they are not universal. Therefore, the performance of the equipment is unstable. Invention content: [0003] The invention provides an integrated satellite positioning vehicle terminal, which reduces the volume of the terminal by selecting more m...
