Description
Technical Field
The application relates to the technical field of train network control, in particular to a method and a device for controlling a train main transformer to work.
Background
At present, a main transformer on a train is cooled through oil circulation, if the oil temperature of the main transformer is too high, all parts in the main transformer are accelerated to age, and the service life of the main transformer is shortened. Therefore, the train network control system monitors the oil temperature of the train main transformer in real time, and when the oil temperature of the train main transformer is too high, the work of the train main transformer needs to be controlled in time so as to protect the train main transformer.
The method can be understood that the effectiveness of monitoring the oil temperature of the train main transformer is guaranteed, and the key of guaranteeing effective protection of the train main transformer is achieved. Therefore, the train network control system monitors whether the oil temperature monitoring sensor of the main transformer of the train has fault phenomena of open circuit, short circuit, communication interruption and the like, so that the faults can be eliminated in time, and the effectiveness of monitoring is ensured. However, there is also a case that if the sensor or the acquisition card responsible for monitoring the oil temperature of the main transformer recognizes that the oil temperature is too high by mistake, the train network control system will automatically reduce the power of the traction converter or disconnect the power supply of the traction converter to protect the main transformer, but this will inevitably reduce the train operation speed and affect the operation order.
However, the network control system of the current train does not judge and identify the effectiveness of the monitored oil temperature data of the main transformer of the train, but directly uses the collected oil temperature data for controlling the work of the main transformer of the train. The control process can cause improper interference on train running and influence the train operation order.

By adopting the technical scheme of the embodiment of the application, the accuracy of the oil temperature data of the main transformer of the train can be accurately identified, and the work of the main transformer of the train is reasonably controlled on the basis.
Fig. 1 shows an application scenario diagram for controlling the operation of a train main transformer, to which the technical solution of the embodiment of the present application is applied. The oil temperature sensors are respectively arranged at the oil inlet 1, the oil inlet 2, the oil outlet 1 and the oil outlet 2 of the main transformer, and the oil temperature sensors collect oil temperature data of the oil inlet of the main transformer and send the collected oil temperature data to the train network control system TCMS. The train network control system uses the received oil temperature data for oil temperature calculation, and executes main transformer protection processing when the main transformer oil temperature is too high.
Fig. 1 illustrates a specific implementation manner of acquiring oil temperature of a train main transformer by taking a main transformer structure with two oil inlets and two oil outlets as an example, and when the technical scheme of the embodiment of the present application is implemented specifically, oil temperature sensors may be respectively arranged for each oil inlet and oil outlet of the train main transformer according to actual conditions to acquire oil temperature data of the oil inlets and send the data to a train network control system TCMS.
An exemplary implementation manner of acquiring and uploading oil temperature data is that oil temperature data of an oil inlet 1 and oil temperature data of an oil outlet 1 are transmitted to a PT100 acquisition circuit board of a high-voltage control unit of a TCMS (train network control system) through a circuit, and are defined as G1 board cards; the oil temperature data of the oil inlet 2 and the oil temperature data of the oil outlet 2 are transmitted to a PT100 acquisition circuit board of another high-voltage control unit of a TCMS (train network control system) through a circuit, and are defined as G2 board cards. The two independent and non-influencing high-pressure control units transmit oil temperature data of the oil inlet 1, oil temperature data of the oil outlet 1, oil temperature data of the oil inlet 2 and oil temperature data of the oil outlet 2 to the TCMS through the existing communication technology.
The method for controlling the operation of the train main transformer provided in the embodiment of the present application is applied to the train network control system shown in fig. 1, and specifically, the method controls the operation of the main transformer, for example, controls the operating power of the main transformer by using the received oil temperature data of each oil port of the train main transformer.
It should be noted that, in the technical solution of the embodiment of the present application, the software program may exist in the train network control system, and when the software program runs, the control of the operation of the train main transformer is implemented. Or, the technical scheme of the embodiment of the application can also exist in a train network control system in a hardware device form, and when the device starts to work, the oil temperature data of each oil port of the main transformer is received, and the work of the train main transformer is controlled according to the oil temperature data. When the technical scheme of the embodiment of the application is used as a hardware device in a train network control system to realize the function of controlling the work of the train main transformer, the hardware device can be specifically a processor, a single chip microcomputer and the like.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application discloses a method for controlling the operation of a main transformer of a train, which is shown in fig. 2 and comprises the following steps:
s201, acquiring main transformer oil temperature data;
specifically, the main transformer oil temperature data refers to oil temperature data of each oil port of the main transformer, for example, oil temperature data of each oil inlet of the main transformer, oil temperature data of each oil outlet, and the like. The oil temperature data is acquired by oil temperature sensors arranged at each oil inlet and each oil outlet of the main transformer.
It should be noted that, the oil temperature sensors disposed at each oil port of the train main transformer periodically collect the oil temperature of each oil port of the train main transformer in a set data collection period, and after one collection period is finished, simultaneously send the collected oil temperature data to the train network control system.
It can be understood that the train network control system also periodically receives the oil temperature data of each oil port of the main transformer, and in a data receiving period, the train network control system can simultaneously receive the oil temperature data of each oil port of the train main transformer, and the train network control system can record and store the main transformer oil temperature data received in each period.
S202, judging whether the main transformer oil temperature data is credible data or not according to the historical oil temperature data of the main transformer;
specifically, the oil temperature sensors of the oil ports of the train main transformer periodically collect oil temperature data of the oil ports and upload the oil temperature data to the train network control system, and the train network control system uses the periodically received oil temperature data of the main transformer to control the work of the train main transformer.
In view of the requirement on the timeliness of train control, the smaller the period of receiving the oil temperature data of the train main transformer by the train network control system is, the better the period is, and it can be understood that in one oil temperature data acquisition period, the oil temperature change of the train main transformer cannot be large due to the small period. That is, in two adjacent oil temperature data acquisition cycles, the oil temperature variation of the train main transformer should be within a set variation range, and if the oil temperature variation exceeds the set variation range, the acquired oil temperature data can be considered to be inaccurate, and the inaccurate oil temperature data cannot be theoretically used for the work control of the train main transformer.
It can be understood that by comparing the train main transformer oil temperature data acquired in the current period with the train main transformer oil temperature data acquired in the historical period, whether the train main transformer oil temperature data acquired in the current period is valid data or not can be judged, namely whether the train main transformer oil temperature data is credible data or not.
And if the main transformer oil temperature data acquired in the current period is determined to be not credible data through judgment, the train network control system does not control the work of the train main transformer, and outputs alarm information to prompt workers to overhaul the oil temperature sensors of the oil ports of the train main transformer.
And if the main transformer oil temperature data is credible data, executing step S203, and controlling the main transformer according to the main transformer oil temperature data.
Specifically, after the main transformer oil temperature data acquired in each period is judged whether to be credible or not, the working of the train main transformer is controlled and processed only according to the credible oil temperature data. The control processing comprises reducing the power of the traction converter, stopping the starting of the main transformer and the like.
Through the introduction, the technical scheme of the embodiment of the application is combined with the historical oil temperature data of the train main transformer, the reliability of the currently acquired main transformer oil temperature data is judged, whether the acquired main transformer oil temperature data is reliable or not is identified, and if the acquired main transformer oil temperature data is reliable, the reliability is used for controlling the work of the train main transformer. The reliability and effectiveness of the basis for controlling the operation of the train main transformer are ensured by the processing process, so that the improper intervention of the operation of the train main transformer caused by inaccurate acquired oil temperature data of the train main transformer can be avoided.
Optionally, in another embodiment of the present application, a specific processing procedure for determining whether the main transformer oil temperature data is credible data according to the historical oil temperature data of the main transformer is disclosed.
Referring to fig. 3, the determining whether the main transformer oil temperature data is credible data according to the historical oil temperature data of the main transformer includes:
s302, judging whether a difference value between the main transformer oil temperature data and the oil temperature data of the last oil temperature monitoring period of the main transformer is larger than a preset first difference value, and S303, judging whether the value of the main transformer oil temperature data is larger than a preset oil temperature value;
and if the difference value between the main transformer oil temperature data and the oil temperature data in the last oil temperature monitoring period of the main transformer is not greater than a preset first difference value, and/or the value of the main transformer oil temperature data is not greater than a preset oil temperature value, executing step S304, and determining that the main transformer oil temperature data is credible data.
Specifically, the first difference is empirically set, and the train main transformer is configured to obtain a maximum value of the difference between the oil temperature data in two adjacent oil temperature acquisition cycles.
The preset oil temperature value refers to the maximum value of the oil temperature of the main transformer of the train.
The first difference and the preset oil temperature value may be empirically set values.
The method comprises the steps of calculating the difference value between oil temperature data detected in the current train main transformer oil temperature monitoring period and oil temperature data detected in the previous oil temperature monitoring period, comparing the difference value with a preset first difference value, and judging whether the difference value is larger than the preset first difference value or not;
meanwhile, whether the value of the detected oil temperature data in the current train main transformer oil temperature monitoring period is larger than a preset oil temperature value or not is judged, namely whether the value of the detected oil temperature data in the current train main transformer oil temperature monitoring period is larger than the maximum value of the train main transformer oil temperature or not is judged.
If the difference value between the detected oil temperature data in the current train main transformer oil temperature monitoring period and the detected oil temperature data in the previous train main transformer oil temperature monitoring period is larger than a preset first difference value, and the value of the detected oil temperature data in the current train main transformer oil temperature monitoring period is larger than a preset oil temperature value, the detected oil temperature data in the current train main transformer oil temperature monitoring period can be determined to be unreliable data, namely data with serious errors.
On the contrary, if the difference between the oil temperature data detected in the current train main transformer oil temperature monitoring period and the oil temperature data detected in the previous train main transformer oil temperature monitoring period is not greater than the preset first difference, and/or the value of the oil temperature data detected in the current train main transformer oil temperature monitoring period is not greater than the preset oil temperature value, the oil temperature data detected in the current train main transformer oil temperature monitoring period can be determined to be credible data, and the credible data can be used as a basis for controlling the operation of the train main transformer.
For example, if the first difference is 15 degrees and the preset oil temperature value is 105 degrees, the embodiment of the present application determines whether the difference between the value of the oil temperature data acquired this time and the value of the oil temperature data acquired in the previous period is greater than 15 degrees and whether the value of the oil temperature data acquired this time is greater than 105 degrees after the oil temperature data of the train main transformer is acquired.
If the difference value between the value of the oil temperature data acquired this time and the value of the oil temperature data acquired in the previous period is greater than 15 degrees, and the value of the oil temperature data acquired this time is greater than 105 degrees, it can be determined that the oil temperature data acquired this time is not credible;
on the contrary, if the difference between the value of the oil temperature data acquired this time and the value of the oil temperature data acquired in the previous cycle is not greater than 15 degrees, and/or the value of the oil temperature data acquired this time is not greater than 105 degrees, it may be determined that the oil temperature data acquired this time is the authentic data.
It should be noted that, when the method for judging whether the oil temperature data is the trusted data is specifically implemented, the method can be implemented by a general programmable logic language.
Steps S301 and S305 in this embodiment correspond to steps S201 and S203 in the method embodiment shown in fig. 2, respectively, and for details, please refer to the contents of the method embodiment shown in fig. 2, which is not described herein again.
Further, referring to fig. 1, since the oil port of the train main transformer is divided into an oil inlet and an oil outlet, and the number of the oil inlet and the oil outlet is not unique, the above main transformer oil temperature data specifically includes oil temperature data of each oil inlet and each oil outlet of the main transformer.
Therefore, in the above-mentioned determining whether the oil temperature data of the main transformer is the reliable data, in the actual implementation, it may be determined whether the oil temperature data of each oil port of the main transformer is the reliable data. As can be seen from fig. 1, the main transformer oil temperature is collected and divided into four paths, namely, the main transformer inlet 1 oil temperature, the inlet 2 oil temperature, the outlet 1 oil temperature, and the outlet 2 oil temperature. If the oil temperature data acquired by a certain path (such as an entrance 1) is not credible, the oil temperature data of the path is recorded as a three-level fault code which is stored in a train network control system, so that when maintenance personnel download the fault data, the fault is found, investigated and analyzed, and the path sensor or the corresponding acquisition board card is replaced, but the three-level fault code is not prompted to a driver, and the normal driving operation of the driver is not interfered. And then, judging whether the oil temperatures of other three paths are credible again, and finally screening out the maximum value of credible oil temperature data by the same judging method, so that the basis for controlling the work of the main transformer of the train can be carried out.
On this basis, referring to fig. 4, the determining, according to the historical oil temperature data of the main transformer, whether the oil temperature data of the main transformer is credible data specifically includes:
s402, judging whether the oil temperature data of the oil inlet with the highest oil temperature of the main transformer is credible data or not according to the historical oil temperature data of the oil inlets and the oil outlets of the main transformer.
Specifically, based on the above, the train main transformer oil temperature data specifically includes oil temperature data of each oil inlet and oil outlet of the train main transformer, historical oil temperature data of the train main transformer, and historical oil temperature data of each oil inlet and oil outlet of the train main transformer.
Since the train network control system generally controls the operation of the train main transformer based on the highest oil temperature of the train main transformer, when the operation of the train main transformer is controlled based on the oil temperature data of each oil inlet and oil outlet of the train main transformer, the operation of the train main transformer also needs to be controlled based on the oil temperature data of the oil inlet or oil outlet with the highest temperature.
Generally, the temperature of an oil inlet of a main transformer of a train is higher than that of an oil outlet, so that after the oil temperature data of each oil inlet and each oil outlet of the main transformer of the train are obtained, the oil temperature data of the oil inlet with the highest temperature is identified, and then whether the oil temperature data of the oil inlet is credible data is judged according to the historical oil temperature data of the corresponding oil inlet of the main transformer, and the specific judgment process can refer to the judgment method in the method embodiment shown in fig. 3.
If the oil temperature data of the oil inlet with the highest oil temperature of the main transformer of the train is determined to be credible data through judgment, executing the step S403, and controlling and processing the work of the main transformer according to the oil temperature data of the oil inlet with the highest oil temperature of the main transformer;
and if the oil temperature data of the oil inlet with the highest oil temperature of the train main transformer is determined to be the unreliable data through judgment, executing the step S404, and selecting the reliable oil temperature data from the oil temperature data of other oil inlets and oil outlets of the train main transformer to control the work of the main transformer.
Specifically, when the oil temperature data of the oil inlet with the highest oil temperature of the train main transformer is judged and confirmed to be the unreliable data, the reliable oil temperature data is selected from the oil temperature data of other oil inlets and oil outlets of the train main transformer to be used for controlling and processing the work of the train main transformer.
Further, since the oil temperature of the oil inlet of the main transformer of the train is higher than the oil temperature of the oil outlet, in the embodiment of the present application, when credible oil temperature data is selected from the oil temperature data of other oil inlets and oil outlets of the main transformer to be used for controlling and processing the operation of the main transformer, it is preferentially determined whether the oil temperature data of each of the other oil inlets of the main transformer is credible data according to the historical oil temperature data of each of the oil inlets and the oil outlets of the main transformer, and the specific determination method can refer to the determination method shown in fig. 3.
And if the oil temperature data of other oil inlets of the main transformer of the train contains credible data, selecting the credible oil temperature data of the oil inlet with the highest oil temperature from the credible oil temperature data of other oil inlets of the main transformer for controlling the work of the main transformer.
If the oil temperature data of other oil inlets of the main transformer of the train does not have the credible data, further judging whether the credible data exists in the oil temperature data of each oil outlet of the main transformer;
if the credible data exist, selecting the credible data with the highest oil temperature in the oil temperature data of the oil outlet of the main transformer for controlling and processing the work of the main transformer;
if the credible data does not exist, alarm information is output, and workers can carry out manual processing.
For example, if it is determined that the oil temperature data of the oil inlet 1 with the highest oil temperature of the main transformer shown in fig. 1 is unreliable data, in this embodiment of the present application, it is continuously determined whether the oil temperature data of the oil inlet 2 of the main transformer is reliable data, and if the oil temperature data is reliable data, the operation of the main transformer is controlled according to the oil temperature data of the oil inlet 2; if the data is not credible data, further judging whether the oil temperature data of the oil outlet 1 and the oil outlet 2 of the main transformer are credible data, and if both the data are credible data, selecting the oil temperature data with the highest oil temperature as the oil temperature data for controlling the transformer to work; if only the oil temperature data of one oil outlet is credible data, the work of the main transformer is controlled and processed according to the credible oil temperature data of the oil outlet; if the credible data does not exist, alarm information is output to prompt workers to carry out manual processing.
Steps S401 and S403 in this embodiment correspond to steps S201 and S203 in the method embodiment shown in fig. 2, respectively, and for details, please refer to the contents of the method embodiment shown in fig. 2, which is not described herein again.

and a control processing unit 120, configured to, when the main transformer oil temperature data is trusted data, perform control processing on the operation of the main transformer according to the main transformer oil temperature data.
Optionally, in another embodiment of the present application, referring to fig. 6, the data determining unit 110 includes:
