Intelligent Terminal

the taxi intelligent terminal management system using the latest GPS and Beidou Positioning Technology and network technology, embedded programming technology, Windows CE terminal operating system, cloud computing technology, the original taxi valuation multiple system, GPS positioning system, the taxi service evaluation system, intelligent light system, monitoring system and one card system. Integration, design a set of complete city taxi intelligent terminal management system, to achieve a high level of management. Double backup location system using GPS positioning and Chinese Beidou Positioning, positioning accuracy, reliable, real-time operational data store upload taxi and reliable data, which can realize safe driving record, automobile security alarm, accident alarm and anti-theft alarm and tracking and control, in the taxi can achieve "flat-share carpool", can realize the time-sharing, people, time, metering and billing and other functions, and improves the bearing rate of the vehicle, more energy saving and environmental protection. The system has broad application prospects and the market space. The system will realize some technical indicators: receive 10 channels, the positioning accuracy of <5 meters, the cold start time <30 seconds, hot start time <3 seconds, GPS relocation time <30 seconds.

Measured Distance

Geophysical measurement relies on the positioning accuracy of GPS (global positioning system). Usually the positioning accuracy is area dependent. This paper uses a commercially available GPS receiver to verify its positioning accuracy with practical measurement in a small area. With a measurement setup in an open ground, the results show that even for the fixed point, the GPS measured positioning error of about 0.234 meter could be observed for a period of time. Of 12 GPS measured distance errors, only one is about 5.7 meters, all others are within the range of 3-5 meters of GPS receiver specification.
