Problems solved by technology

[0004] Current problems: due to the different electrical characteristics of each track circuit, station maintenance personnel need to set different alarm ranges for the limit values ​​of each track circuit, and each station has many track circuits, and as time goes by The electrical characteristics of the track circuit will also change, so it takes a lot of work for the station personnel to set the limit
In addition, limited by the professional ability of maintenance personnel, some limit values ​​are set unreasonably. If the range setting is too small, more electrical characteristic over-limit alarms will be generated, and the prompt function of the alarm will be lost.
If the range is set too large, it is equivalent to no limit value is set, and the circuit actually fails, and the station personnel do not know it, which has a great potential safety hazard

Embodiment 1

[0025] as attached figure 1 As shown, a track circuit alarm limit adjustment method based on big data, setting acquisition module, storage module and analysis module;

[0026] The track circuit alarm limit adjustment method includes the following steps:

[0027] Step 1, the acquisition module collects the electrical characteristic parameters of each track circuit in each station in real time, and stores them in the storage module in order of the magnitude of the electrical characteristic parameters;

[0028] Step 2, the analysis module traverses the electrical characteristic parameters from the current moment to the preset time in the storage module, and obtains the fluctuation range of the electrical characteristic parameters; the step 2 specifically includes the following steps:

[0029] Step 2.1, using several multiples of the minimum fluctuation unit of the electrical characteristic parameters of the track circuit as reference values, dividing the electrical characteristi...

Embodiment 2

[0040] This embodiment provides a method for adjusting the alarm limit of the track circuit whose electrical characteristic parameter is the ZPW2000 power output voltage; the acquisition module, the storage module and the analysis module are set in the station computer monitoring system. The storage module stores the value per second of each track circuit tested in the monitoring system, and the data volume of the ZPW2000 power output voltage value of each device per day is 24*3600 data.

[0041] The analysis module traverses all the stored ZPW2000 power output voltage values ​​of each device in the storage module within the last 90 days. Since the track circuit is sensitive to the ambient temperature, the test found that the preset time period is set to 90 days It is suitable as a storage base, and the total ZPW2000 power output voltage value data volume that each device needs to traverse is 90*24*3600 data.

[0042] Taking 10 times the minimum fluctuation unit of each track ...

Embodiment 3

[0045] The difference between this embodiment and Embodiment 2 is that the electrical characteristic parameter is the ZPW2000 power output current, and the ZPW2000 power output current value fluctuates around 110mA, and the minimum fluctuation unit is 0.1mA. Then, taking 1mA as a reference value, the The total data volume of the ZPW2000 power output current value is divided into several sub-intervals; the number of points in the combined new basic interval reaches 90%-98% of the total data volume. In the actual environment, it can be 90%, 92%, 95% or 98% is the fluctuation interval of the ZPW2000 power output current value of this track circuit; the station microcomputer monitoring system dynamically adjusts the alarm upper limit and alarm lower limit of the ZPW2000 power output current value in real time according to the fluctuation range of the ZPW2000 power output current value.

Abstract

The invention provides a big data based alarm limit value adjusting method of track circuits. A collection module, a storage module and an analysis module are arranged. The method comprises the following steps that 1) the collection module collects electrical characteristic parameters of all the track circuits in all stations in real time, and stores the electrical characteristic parameters according to the sequence of magnetide; 2) the analysis module traverses the electrical characteristic parameters from present time to preset time in the storage module, and obtains a fluctuation interval of the electrical characteristic parameters; and 3) the analysis module adjusts an alarm limit value of the parameter according to the fluctuation interval. The method has the advantages of scientificdesign, high practicality and reliability and saving time and labor.

Description

technical field [0001] The invention relates to the technical field of track circuit alarms, in particular to a method for adjusting track circuit alarm limit values ​​based on big data. Background technique [0002] The track circuit plays a role in ensuring the safety of driving and shunting operations in the railway, and the track circuit alarm is an important alarm that railway maintenance personnel need to deal with. [0003] The track circuit electrical characteristic overrun alarm is a common alarm in the track circuit. The principle of the alarm is: suppose the voltage value of a certain track under normal conditions is 200mv to 250mv, if the voltage value tested by the microcomputer monitoring system exceeds this range, the system will generate an electrical characteristic overrun alarm to remind maintenance personnel to deal with the problem in time to eliminate potential safety hazards. [0004] Current problems: due to the different electrical characteristics of...
