Abstract

The invention discloses a cab signal remote real-time monitoring system in the field of monitoring systems. The system comprises a user terminal, a cab signal supervising center and a vehicle-mounted system, wherein the user terminal comprises a railway management system connected to the Internet; the cab signal supervising center comprises a central server which is connected with a local database, and a signal output terminal of the central server is connected with a signal input terminal of a dynamic domain name server which is also connected with the China mobile GPRS network; the China mobile GPRS network is also connected to the central server; and the vehicle-mounted system comprises a plurality of GPRS data transmission cases connected to the China mobile GPRS network, and the GPRS data transmission cases are connected to a cab signal main engine. The system disclosed by the invention has the advantages of simple structure, low cost and higher real time performance, and can be used for railroad cab signal systems.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a remote real-time monitoring system. Background technique [0002] GPRS (General Packet Radio Service) is a new bearer service developed on the existing GSM system, and its purpose is to provide GSM users with packet-based data services. 6PRS adopts the same wireless modulation standard and frequency band as GSM, the same burst structure, frequency hopping rules and TDMA frame structure. This new packet data channel is very similar to the current circuit-switched voice service channel. Therefore, the existing base station sub The system (BSS) provides comprehensive GPRS coverage from the outset. GPRS allows users to send and receive data in the end-to-end packet transfer mode without using network resources in circuit switching mode, thus providing an efficient and low-cost wireless packet data service. It is especially suitable for intermittent, sudden, frequent and a small amount of da...
