Embodiment Construction

[0017] Fig. 3 discloses a satellite positioning monitoring system 10, which is used for safety warning of cars driving in a long tunnel, and the system includes: a GPS satellite receiving module 11 for receiving GPS satellite signals.

[0018] A database 16 has a number of safety warning data built in it; the data in the database 16 includes vehicle identification codes, air quality safety indicators, standard comparison values ​​of signal interruption time, tunnel coordinates, etc.

[0019] A time distance detection unit 13, used to detect the interruption time of the GPS satellite signal received by the information processing unit 19, and transmit it to the information processing unit 19 for comparison to confirm whether it has not been received for too long and exceeds the preset time , to check whether the time to enter the tunnel is too long.

[0020] An information processing unit 19 is connected with the database 16 and the time distance detection unit 13 respectively, ...

Abstract

The present invention provides a GPS secondary planet monitoring system and method thereof which is used in safety caution when the automobile is traveling in long tunnel, comprising of: a GPS secondary planet receiving module, a data base, a time-distance detecting unit to sense intermitting time in output signal and a information process unit to receive information date of output signal and signal intermitting time, and obtaining one of safety caution data by data base to compare information data of signal intermitting time to safety caution data, and producing a caution inform when the intermitting time of output signal exceeds the presupposition conditions of safety caution data. Also comprising of caution device to output a caution signal after receiving caution inform of information process unit.

Description

【Technical field】 [0001] The invention relates to a satellite positioning monitoring system, which is applied to the safety warning of automobiles driving in long tunnels, in particular to a good satellite positioning monitoring system applied to safety warnings of automobiles driving in long tunnels. 【Background technique】 [0002] Due to the rapid increase of vehicles in many areas of the world, traffic congestion has become a major problem, and traffic congestion can also cause air pollution problems. Especially for urban areas with a small area and a large number of people, the peak hours of commuting traffic in the surrounding areas of the city, and because leisure activities in the countryside have become an indispensable part of people's daily life today, the problem of traffic congestion is even more serious. When working in a tunnel, it is easy to cause poor air quality in the tunnel, especially in traffic jams. If people are exposed to vehicle exhaust for a long ti...
