Description
Technical field
The present invention relates to a kind of on-line detecting system and detection method thereof, particularly relate to a kind of on-line detecting system for track traffic and detection method thereof.
Background technology
In the track traffic industry, the means that detect track traffic equipment are more and more at present, are the corresponding communication protocol of a passage in the communication process of general testing process, and transmit and receive data by described passage.For the real-time data, generally all be to create a stipulations processing threads the corresponding stipulations of passage are bound processing, stipulations and upper layer application integrate usually.For slower device status data of variation such as picture transformer oil chromatographic data, only record once every day usually, thus adopt the database mode storage usually, so have to correspondingly increase a database thread process.For the be engaged in data of system and dc load etc. of signal system, worker, owing to all be the data that transmit in real time, so need a plurality of stipulations to be integrated in the upper layer application equally.Too high like this coupling causes the autgmentability of upper layer application poor, can not reach the effect of the concurrent response of data, so cause existing in the communication process of testing process 2 deficiencies: the one, increase new stipulations or revise when having stipulations now, whole upper layer application need recompilate or arrange; The 2nd, when the obstructed institute of network communication causes stopping up, real-time data also usually need to wait for and change after data dispose slowly, just have an opportunity to line up and arrive and correspondingly handle, but this moment, real time data became invalid historical data, so cause the no longer effective property of real time data.
Summary of the invention
The technical problem to be solved in the present invention be for the track traffic that overcomes prior art detect in stipulations and upper layer application integrated level too high, the defective of communication protocol that caused the upper layer application close coupling provides a kind of on-line detecting system and detection method thereof of track traffic.
The present invention solves above-mentioned technical problem by following technical proposals:
The invention provides a kind of on-line detecting system for track traffic, wherein said on-line detecting system comprises: a plurality of device drives unit, the source code data that are used for gathering external equipment; Wherein mapping relations are all set up with a source code shared buffer memory unit in each device drives unit, and a communication port is set up respectively and between the described source code shared buffer memory unit in each device drives unit;
