To facilitate understanding of the filter screen monitoring method provided in the present application, a traction converter system to which the filter screen monitoring method is applied is described below, please refer to fig. 1, where fig. 1 is a schematic structural diagram of the traction converter system provided in the present application, the traction converter system includes a heat sink 01, a function module 02, a control device 03, a network device 04, a plurality of temperature sensors, and the like, and the plurality of temperature sensors include a temperature sensor 05 disposed at a water inlet of the heat sink, a temperature sensor 06 disposed at a water outlet of the heat sink, and a temperature sensor 07 disposed outdoors. Wherein, functional module 02 during operation produces the heat, through coolant liquid with heat transfer to radiator 01 in, radiator 01 utilizes the cooling air with the heat in the air that looses, for guaranteeing radiator 01 unblock, sets up the filter screen at radiator 01's front end and filters, and the coolant liquid after the cooling circulates to functional module 02 again, continues to take away the heat that functional module 02 produced, circulates in proper order.

The filter screen monitoring method can be realized by the control device of the vehicle, and the filter screen monitoring method provided by the application is explained in detail below.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a method for monitoring a filter screen according to the present disclosure, the method comprising:
s101: acquiring outdoor temperature data and temperature data of a target radiator, wherein the target radiator comprises a vehicle radiator and other vehicle radiators;
it can be understood that the temperature data of the water inlet/outlet of the radiator can reflect the heat dissipation capacity of the radiator, the heat dissipation capacity of the radiator is influenced by the state of a filter screen at the front end of the radiator, when the filter screen is blocked, the radiator cannot dissipate heat normally, and each device in the traction converter system has abnormal temperature. Therefore, the temperature data of the water inlet/outlet of the radiator of the vehicle can be used as one basis for judging the state of the filter screen, wherein the state can be blocked or normal.
Specifically, when the filter screen states of the traction converter systems of the respective trains are normal in the same train, the temperature data of the radiators of the respective trains should have a small difference, and therefore, the temperature data of the radiators obtained in this step includes the temperature data of the radiator of the respective train and the temperature data of the radiators of the other trains, so that the temperature data of the radiator of the respective train and the temperature data of the radiators of the other trains are compared in the following step, and the filter screen state of the radiator of the respective train is determined. Specifically, for avoiding the problem that the filter screens of the radiators of multiple vehicles are blocked simultaneously, and therefore the judgment error is caused, outdoor temperature data are obtained in the step, auxiliary judgment is carried out, and therefore the accuracy and the reliability of filter screen state judgment are improved.
Specifically, outdoor temperature data can be acquired through a temperature sensor arranged outdoors, the control device of the vehicle can acquire the outdoor temperature data through a network device, the temperature of a water inlet of the radiator can be acquired through a temperature sensor arranged at a water inlet of a target radiator, the temperature of a water outlet of the radiator can be acquired through a temperature sensor arranged at a water outlet of the target radiator, and meanwhile, the control device of the vehicle can acquire the temperature of the water inlet and the temperature of the water outlet of the radiator of another vehicle through the network device. In this step, the outdoor temperature data and the temperature data of the target radiator may be acquired according to a preset acquisition cycle, or the outdoor temperature data and the temperature data of the target radiator may be acquired after receiving the acquisition instruction.
Of course, in order to improve the accuracy and reliability of data acquisition, the temperature data may be acquired multiple times within a preset time period, and the currently acquired outdoor temperature data and the temperature data of the target radiator may be calculated by taking an average value.
S102: judging whether the filter screen of the radiator meets the blockage early warning condition or not according to the outdoor temperature data and/or the temperature data of the target radiator, if so, executing S103;
s103: and executing early warning operation.
Specifically, in this embodiment, whether the filter screen of the radiator meets the blockage warning condition is determined according to the outdoor temperature data, the water inlet temperature of the radiator, the water outlet temperature of the radiator, the water inlet temperature of the radiator of another vehicle, and the water outlet temperature of the radiator of another vehicle, where the blockage warning condition may correspond to that the filter screen is likely to be blocked, and the filter screen state determination in the present application does not require a preset detection period, so as to achieve the purpose of overhaul in advance or overhaul extension.
As a preferred embodiment, the blockage warning condition may be: the absolute value of the temperature of a water inlet of the vehicle radiator exceeds a first preset threshold value; and/or the absolute value of the temperature of the water outlet of the vehicle radiator exceeds a second preset threshold value.
Specifically, when the traction converter normally operates and the filter screen is in a non-blocking normal state, the temperature of the water inlet and the temperature of the water outlet of the radiator of the vehicle are both in respective corresponding preset ranges, if the absolute value of the temperature of the water inlet of the radiator of the vehicle exceeds a first preset threshold value, the absolute value of the temperature of the water outlet of the radiator of the vehicle exceeds a second preset threshold value, and any one of the conditions or all the conditions is met, it can be judged that the filter screen of the radiator of the vehicle meets the blocking early warning condition. In order to improve the accuracy and reliability of the determination, the blockage warning condition may specifically be that the duration that the absolute value of the temperature of the water inlet of the vehicle radiator exceeds the first preset threshold exceeds a first preset time, and/or the duration that the absolute value of the temperature of the water outlet of the vehicle radiator exceeds the second preset threshold exceeds a second preset time. For example, assuming that the absolute value of the temperature of the water inlet of the vehicle radiator exceeds 65 ℃ and lasts for 1min, and/or the absolute value of the temperature of the water outlet of the vehicle radiator exceeds 60 ℃ and lasts for 1min, it is determined that the filter screen of the vehicle radiator meets the blockage early warning condition.
Of course, the first preset threshold, the second preset threshold, the first preset time and the second preset time may be set according to actual engineering requirements, and the application is not specifically limited herein.
As a preferred embodiment, the blockage warning condition may be that a difference between a temperature of a water inlet of the vehicle radiator and a temperature of a water outlet of the vehicle radiator is smaller than a third preset threshold.
Specifically, when the converter works normally and the radiator radiates heat normally, the temperature of the water outlet of the radiator should be lower than the temperature of the water inlet of the radiator, the difference value between the temperature of the water inlet and the temperature of the water outlet should be within a preset range, if the difference value is not within the preset range, the radiator does not radiate heat normally, and the blockage of the filter screen is a main reason of the radiator which does not radiate heat normally. In order to improve the accuracy and reliability of the determination, the blockage warning condition may be that the duration of time during which the difference between the temperature of the water inlet of the vehicle radiator and the temperature of the water outlet of the vehicle radiator is less than a third preset threshold exceeds a third preset time. For example, when the difference between the temperature of the water inlet and the temperature of the water outlet of the radiator is less than 3 ℃ and lasts for 1min, the filter screen of the radiator meets the blockage early warning condition.
Of course, the third preset threshold and the third preset time may be set according to actual engineering requirements, and this embodiment is not specifically limited herein.
As a preferred embodiment, the blockage warning condition may be: the difference value between the water inlet temperature of the vehicle radiator and the outdoor temperature data is larger than a fourth preset threshold value; and/or the difference value between the water outlet temperature of the vehicle radiator and the outdoor temperature data is larger than a fifth preset threshold value.
Specifically, in order to avoid the situation that the filter screens of multiple cars are blocked at the same time, the temperature of the water inlet/outlet of the radiator is compared with the outdoor temperature, and it can be understood that when the converter operates normally and stably, the radiator operates normally, the temperature rise of the radiator is within a fixed range, and if the temperature rise is higher than the fixed range, the abnormal situation of the equipment is caused, the radiator does not radiate heat normally, and the filter screen blocking is a main reason for the abnormal radiation of the radiator. Based on the method, when the difference value between the water inlet temperature of the vehicle radiator and the outdoor temperature data is larger than a fourth preset threshold value, and/or the difference value between the water outlet temperature of the vehicle radiator and the outdoor temperature data is larger than a fifth preset threshold value, the fact that the vehicle radiator filter screen meets the blockage early warning condition can be judged. In order to improve the accuracy and reliability of the judgment, the blockage early warning condition may specifically be that the duration of the difference between the temperature of the water inlet of the radiator of the vehicle and the outdoor temperature data is greater than a fourth preset threshold is greater than a fourth preset time; and/or the duration of the difference value between the water outlet temperature of the vehicle radiator and the outdoor temperature data, which is greater than a fifth preset threshold value, is greater than a fifth preset time. For example, when the difference between the temperature of the water inlet of the vehicle radiator and the outdoor temperature exceeds 20 ℃ and lasts for 1min, and/or the difference between the temperature of the water outlet of the vehicle radiator and the outdoor temperature exceeds 15 ℃ and lasts for 1min, it is indicated that the filter screen of the vehicle radiator meets the blockage early warning condition.
Of course, the fourth preset threshold, the fifth preset threshold, the fourth preset time and the fifth preset time may be set according to actual engineering requirements, and this embodiment is not specifically limited herein.
As a preferred embodiment, the blockage warning condition may be that a difference between the temperature of the water inlet of the radiator of the vehicle and the temperature of the water inlet of the radiator of the other vehicle is greater than a sixth preset threshold; and/or the difference value between the temperature of the water outlet of the vehicle radiator and the temperature of the water outlet of the other vehicle radiators is larger than a seventh preset threshold value.
Specifically, when the traction converter system of each train of the same train and each train normally works, the difference value of the temperatures of the water inlet/outlet of the radiator of each train is not large, and the temperature is within a preset range. In this embodiment, the temperature of the water inlet of the radiator of the vehicle is compared with the temperatures of the water inlets of the radiators of other vehicles, if the difference value is greater than the sixth preset value, it is indicated that the filter screen of the radiator of one vehicle meets the blockage early warning condition, generally, the filter screen of the radiator with the higher temperature of the water inlet is the filter screen meeting the blockage early warning condition, and the temperature of the water outlet is determined in the same manner. In order to improve the accuracy and reliability of the judgment, the blockage early warning condition may specifically be that the duration of the difference between the temperature of the water inlet of the radiator of the vehicle and the temperature of the water inlet of the radiator of the other vehicle being greater than a sixth preset threshold is greater than a sixth preset time; and/or the duration time that the difference value between the temperature of the water outlet of the vehicle radiator and the temperature of the water outlet of the other vehicle radiators is greater than a seventh preset threshold value is greater than seventh preset time. For example, when the difference between the temperature of the water inlet of the radiator of the vehicle and the temperature of the water inlet of any one of the radiators of the other vehicles exceeds 5 ℃ and lasts for 1min, and/or the difference between the temperature of the water outlet of the radiator of the vehicle and the temperature of the water outlet of any one of the radiators of the other vehicles exceeds 5 ℃ and lasts for 1min, and the temperature of the water inlet or the temperature of the water outlet of the radiator of the vehicle is higher, it is indicated that the filter screen of the radiator of the vehicle meets the blockage.
Of course, the sixth preset threshold, the seventh preset threshold, the sixth preset time and the seventh preset time may be set according to actual engineering requirements, and this embodiment is not specifically limited herein.
It can be understood that, when the blockage pre-warning condition described in any one or any several of the above embodiments is met, the pre-warning operation is executed to remind an operator of paying attention, and the filter screens meeting the blockage pre-warning condition are replaced, cleaned, and the like in time. As a preferred embodiment, the performing of the early warning operation includes: the method comprises the steps of generating early warning signals, and transmitting the early warning signals to a prompting device arranged in a cab of the rail transit vehicle through a network device so as to prompt information corresponding to the early warning signals through the prompting device. The prompting device may be a display, an indicator light, a buzzer, etc., and the generation manner of the warning device and the warning signal is not specifically limited in this application.
It can be seen that, in this embodiment, it is considered that temperature data of a radiator is affected when a filter screen of the radiator is blocked, so that outdoor temperature data, temperature data of a radiator of a vehicle and temperature data of radiators of other vehicles are obtained first, and since the temperature data of the radiators of the other vehicles in the same train are not greatly different when the radiators of the vehicles normally operate, the temperature data of the radiators of the other vehicles can be used as a basis for judging whether the filter screen of the radiator of the vehicle is blocked, so as to avoid the situation that the filter screens of the radiator of the vehicle and the radiators of the other vehicles are blocked at the same time, the outdoor temperature data can be also obtained as another basis for judging whether the filter screen of the radiator of the vehicle is blocked, and the filter screen of the radiator of the vehicle is judged by integrating the outdoor temperature data and the temperature data of the radiators of.
