In an embodiment, the collecting component performs overrun detection on the temperature data to obtain an overrun detection result, which specifically includes:
first, a current dynamic temperature threshold and a temperature change rate are determined.
In one specific implementation, determining the current dynamic temperature threshold value specifically includes:
the first step, obtaining effective working time period and environment information of the cable head of the railway contact network.
In practical application, the effective working period of the cable head of the railway overhead contact system can be determined according to the basic period of the operation of the railway overhead contact system and the working period recorded by the working ticket of the overhead contact system.
The environmental information can be determined according to weather forecast of the area where the railway contact net is located, and the environmental information specifically comprises information such as environmental temperature, environmental humidity, wire icing state and the like.
And secondly, determining a first temperature threshold corresponding to the effective working period through a preset period-temperature threshold comparison table.
In this embodiment, the time period-temperature threshold value comparison table records temperature threshold values corresponding to different working time periods of the railway catenary, specifically, the corresponding temperature threshold values can be set according to line load conditions of different time periods in a day, when the load is large, the temperature threshold values can be properly increased, and when the load is small, the temperature threshold values can be properly reduced. The specific temperature threshold value can be reasonably set according to actual requirements.
And thirdly, determining a second temperature threshold corresponding to the environmental information through a preset environment-temperature threshold comparison table.
In this embodiment, the environmental-temperature threshold value comparison table records corresponding temperature threshold values under different environmental states, and takes an environmental temperature as an example, when the environmental temperature is high, the temperature threshold value can be properly increased, and when the environmental temperature is low, the temperature threshold value can be properly reduced. The specific temperature threshold value can be reasonably set according to actual requirements.
And step four, carrying out average value calculation on the first temperature threshold value and the second temperature threshold value to obtain the current dynamic temperature threshold value.
It can be appreciated that, in this embodiment, the two temperature thresholds obtained above may be integrated by means of the averaging operation, so that the temperature thresholds may be dynamically set according to the effective operating period and the environmental information.
In this embodiment, the temperature change rate may be a mean value of the temperature change in the current period consistent with the dynamic temperature threshold, that is, the temperature change rate may represent a temperature data fluctuation condition of the cable head in the current period.
In one aspect, whether the temperature data is below a dynamic temperature threshold is determined, and a first determination result is obtained.
On the other hand, whether the temperature change rate is within the set change rate interval is judged, and a second judgment result is obtained.
Finally, an overrun detection result is obtained according to the first judgment result and the second judgment result.
In a specific implementation, obtaining an overrun detection result according to the first determination result and the second determination result specifically includes:
If the first judging result and the second judging result are both yes, the overrun detecting result is abnormal overrun data.
If at least one of the first judging result and the second judging result is negative, the overrun detecting result is abnormal overrun data.
In this embodiment, by combining the overrun condition of the temperature data and the overrun condition of the temperature change rate, the overrun detection result with a more reference value can be obtained, so that an effective data basis is provided for subsequent data reporting and abnormal alarm.
In one embodiment, the acquisition component may also be configured to:
firstly, dividing temperature data into data cache queues with different priorities according to positions of corresponding key monitoring points.
In this embodiment, the temperature data may be divided into data cache queues with different priorities according to the positions of the key monitoring points. In practical application, when the position of the key monitoring point is a high-load section, the priority of the temperature data is highest, and can be set to be first-level and should be cached preferentially, when the position of the key monitoring point is a hub station, the priority of the temperature data is higher, and can be set to be second-level, and when the position of the key monitoring point is a curve, the priority of the temperature data can be generally set to be third-level.
And then, according to the data caching conditions corresponding to different priorities, carrying out hierarchical caching on the temperature data in each data caching queue.
In the process of hierarchical caching, different data caching periods can be set according to different priorities, for example, temperature data with a first level of priority can be cached for a longer time, for example, 10 days, temperature data with a second level of priority can be cached for a shorter time, for example, 5 days, and temperature data with a third level of priority can be cached for a shorter time, for example, 2 days or 1 day. Therefore, the data caching pressure can be reduced through the hierarchical setting of the caching period, so that the data caching process is more targeted.
