Method for generating PIS log equivalent running chart by taking train as statistical unit

Abstract

The embodiment of the invention provides a PIS log equivalent running chart generation method taking a train as a statistical unit. The method comprises the following steps: extracting PIS log data from PIS equipment, and segmenting the PIS log data in a frame format; extracting train operation data in each frame of data after segmentation, and storing the train operation data in a first data chain table; analyzing the train operation data in the first data chain table, and storing the obtained arrival time and departure time of the train in a second data chain table; and generating a runningchart curve according to the second data chain table. In this manner, under the condition that a train is used as a research object; the state of each train in the platform train data is extracted toform a mode similar to a running chart to be displayed, so that the PIS log and the running chart have comparability, an operator can judge data packet loss or data errors between the ATS front-end processor and the PIS equipment conveniently, and meanwhile, the workload of the operator is reduced.

Description

technical field [0001] Embodiments of the present invention generally relate to the rail transit field, and more specifically, relate to a method for generating a PIS log-equivalent operation diagram with a train as a statistical unit. Background technique [0002] The interaction data between ATS front-end unit and PIS (passenger information system) equipment is recorded in log form, and the rationality and real-timeness of the data can be judged by analyzing the log. The ATS front-end machine will save the data it sends and receives locally, and the PIS device can also save the received and sent data. By calculating the time difference between the sending and receiving data at the ATS end, the reliability of the communication between devices can be evaluated. However, this method cannot detect the significance of the data sent by the ATS communication front-end processor. [0003] The data sent by the ATS front-end processor to the PIS equipment is based on the platform, ...

Problems solved by technology

If time is used as a variable and the platform is used as the analysis object, only the change of the status of the platform over time between the arrival and arrival of the station can be obtained. This analysis is relatively weak and can only be independently analyzed for PIS data. , can not be directly compared with the operation diagram, the train data in the operation data needs to be converted into the information about the arrival and arrival of the station, and in the real situation, the general operation diagram will not record the information about the arrival of the station
