Special GNSS receiver for high-speed railway monitoring

Abstract

The invention relates to the technical field of GNSS receivers, in particular to a special GNSS receiver for high-speed railway monitoring. The receiver comprises a GNSS circuit board and a communication module; the GNSS circuit board comprises an ARM processor and a GNSS board card; the GNSS board card is used for performing accurate positioning; the communication module and the GNSS board card are both connected with the ARM processor; the ARM processor receives and processes instructions and data transmitted by the communication module; and the communication module comprises an LAN module,a 3G module, a 4G module, a WIFI module and a Beidou short message module. Multiple network modes are automatically combined, and an optimal route is selected according to a network environment duringtransmission, so that data transmission is more efficient, securer and faster, and the reliability, stability and security of the data transmission are ensured.

Description

technical field [0001] The invention relates to the technical field of GNSS receivers, in particular to a special GNSS receiver for high-speed rail monitoring. Background technique [0002] Satellite navigation and positioning technology has been widely used in the world, and the material basis of the wide application is the satellite navigation receiver. Currently, GNSS receivers are the most widely used, and single-frequency C / A code civil navigation receivers are the most widely used. In addition to this kind of receiver that is generally suitable for civilian use, there are also dual-frequency receivers and GPS / GLONASS dual-system compatible machines. According to the report of "GPSWORLD" magazine, there are now more than a thousand GNSS receiver manufacturers in the world, and a total of tens of thousands of models of receivers have entered the commercial market. There are various types of GNSS receivers, including C / A code and P code, single frequency and dual freque...

AI Technical Summary

Problems solved by technology

At the same time, new problems also follow. Affected by the singleness and instability of the network connection mode of most GNSS receivers at present, once a failure occurs during the operation of the high-speed rail, the network of the GNSS receiver also fails. GNSS receivers will not be able to monitor and warn high-speed rail in time, which may cause major accidents and losses

[0003] Although there are all kinds of receivers on the market, the communication mode is relatively single, which is greatly affected by the environment and operators. At the same time, the cost is high and the stability is poor. It cannot meet the standard for safety monitoring such as high-speed rail.
