On-line detection system and detection method for rail transit

Abstract

The invention discloses an online detection system for rail transit and a detection method of the online detection system. The online detection system comprises a plurality of equipment driving units, a protocol driving unit and a transmitting unit, wherein the equipment driving units are used for collecting source code data of external equipment; a communication channel is built between each equipment driving unit and a source code sharing cache unit; the protocol driving unit is used for controlling the equipment driving units to collect the source code data of the external equipment, and the source code data are sent and stored in the source code sharing cache unit in a packaging mode; the protocol driving unit is further used for sequentially detecting whether the source code data collected by all the equipment driving units change; the transmitting unit is used for transmitting the source code data having changing marks in the source code data of the source code sharing cache unit to an external system. The online detection system for the rail transit and the detection method of the online detection system reduce strong coupling among equipment driving, protocol driving, a data base and upper application, and bring convenience to maintenance and expansion of the equipment driving, the protocol driving, the data base and the upper application.

Description

technical field [0001] The invention relates to an on-line detection system and a detection method thereof, in particular to an on-line detection system and a detection method for rail transit. Background technique [0002] At present, in the rail transit industry, there are more and more means of detecting rail transit equipment. In the communication process of the general detection process, one channel corresponds to one communication protocol, and data is sent and received through the channel. For real-time data, a protocol processing thread is generally created to bind the protocol corresponding to the channel for processing, and the protocol and upper-layer applications are usually integrated together. For equipment status data that changes slowly, such as transformer oil chromatographic data, it is usually only recorded once a day, so it is usually stored in a database, so a database thread has to be added accordingly. As for the data of signal system, public works sy...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the defect that the protocol and the upper-layer application are too high integrated in the prior art rail transit detection, which leads to the defect that the upper-layer application is strongly coupled with the communication protocol, and to provide an online rail transit detection system and its detection method
