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 inventor of the application discovers that in the traditional technology, an air speed sensor can be arranged on a key air channel of a train, and whether a fault occurs in an air supply system is determined according to the comparison between the result detected by the air speed sensor and a standard value. However, since the air supply system is complex and the air volume varies greatly with the different routes, a certain fixed standard value cannot be applied to all routes. In addition, the installation of the wind speed sensor also requires a certain cost, and the wind speed sensor itself may be out of order. Therefore, it is impossible to accurately determine whether or not the air supply system of the train running on each intersection is faulty by using this method.
In order to solve the above problem, an embodiment of the present application provides a fault determination method, and in particular, considering that whether a fault exists in an air supply system of a vehicle can be reflected by the number of times of wind blowing of an air compressor during a running process of the vehicle, because the wind volume of each wind blowing of the air compressor is substantially the same, the number of times of wind blowing of the air compressor can infer the total wind volume used by the vehicle for executing the vehicle, and the wind volume of a vehicle of the same model for normally executing the vehicle does not greatly float, so the number of times of wind blowing of the air compressor can be used as a basis for determining whether the fault exists in the air supply system, and in the embodiment of the present application, when determining whether the fault exists in the air supply system of the target vehicle, the number of times of wind blowing of the air compressor of the. In addition, considering that the number of times of wind blowing of the air compressor of the vehicle is related to the traffic route traveled by the vehicle and the model of the vehicle, in the embodiment of the present application, the threshold value of the number of times of wind blowing corresponding to the target vehicle may be determined based on the traffic route traveled by the target vehicle and the model of the target vehicle. And determining whether the air supply system of the target vehicle has a fault or not by comparing the wind-blowing frequency threshold value with the wind-blowing frequency of the air compressor of the target vehicle. Specifically, the number information, the model information, and the wind pressure information of the target vehicle may be acquired. The vehicle information may represent the road crossing traveled by the target vehicle. Then, determining the number of times of wind blowing of an air compressor of the target vehicle according to the wind pressure information of the target vehicle; determining a corresponding wind-up frequency threshold according to the train number information and the model information of the target vehicle; and if the wind blowing times of the air compressor of the target vehicle are larger than the wind blowing time threshold value, determining that the wind supply system of the target vehicle is in fault. Since the aforementioned threshold value of the number of times of wind is determined based on the number information and the model information of the target vehicle, that is, matched with the traffic traveled by the target vehicle and the information of the target vehicle itself. Therefore, by the scheme provided by the embodiment of the application, whether the air supply system of the target vehicle has a fault or not can be accurately determined.
Moreover, compared with the scheme that the wind speed sensor is installed on the key air duct, the fault determining scheme provided by the embodiment of the application can reduce the cost investment for determining whether the wind supply system has faults or not. For a vehicle, the cost investment for determining whether the air supply system has a fault can be saved by ten thousand yuan to dozens of ten thousand yuan each year by adopting the scheme provided by the embodiment of the application.
Various non-limiting embodiments of the present application are described in detail below with reference to the accompanying drawings.
Exemplary method
Referring to fig. 1, the figure is a schematic flow chart of a fault determination method provided in an embodiment of the present application.
The fault determination method provided in the embodiment of the present application may be executed by a server or a terminal device, and the embodiment of the present application is not particularly limited.
The embodiment of the present application is not particularly limited to the server, and the server may be a dedicated server specially used for determining whether the air supply system of the vehicle is faulty, and of course, the server may also be a server further having other data processing functions, and of course, the embodiment of the present application is not particularly limited.
The terminal device is not particularly limited in the embodiments of the present application, and the terminal device may be, for example, a vehicle-mounted terminal on a vehicle, for example, in the case of a train of multiple units, the terminal device may be a terminal device in a train control room.
The fault determination method provided in the embodiment of the present application can be implemented, for example, by the following steps S101 to S104.
S101: and acquiring the train number information, the model information and the wind pressure information of the target vehicle.
It should be noted that the target vehicle may be a high-speed train of multiple units.
It should be noted that, in the embodiment of the present application, the train number information of the target vehicle includes a train number of the target vehicle, for example, the train number of the target vehicle may be G, and for example, the train number of the target vehicle may be D, which is not illustrated in this application.
In the embodiment of the present application, the model information of the target vehicle is information describing a model of the target vehicle. The model of the target vehicle is not specifically limited in the embodiments of the present application, and the model of the target vehicle may be, for example, a "harmony number", or the model of the target vehicle may be, for example, a "renaissance number", and the like, which are not necessarily illustrated here.
In an embodiment of the present application, the wind pressure information of the target vehicle includes information describing a wind pressure of an air compressor of the target vehicle.
In the embodiment of the application, the train number information and the model information input by a user through a man-machine interaction interface can be acquired. For example, a user inputs train number information and model information of a target vehicle on a train information input interface displayed by a terminal device, and the terminal device obtains the train number information of the target vehicle and the train number information of the target vehicle by acquiring the content input by the user.
In the embodiment of the present application, the wind pressure information of the target vehicle may be acquired by using a corresponding wind pressure detection device, for example, the wind pressure information of the target vehicle may be acquired by using a sensor that detects wind pressure.
It should be noted that, in practical applications, when the target vehicle is in a driving process, corresponding wind pressure may change, and the change of the wind pressure may reflect whether the air supply system of the target vehicle fails to a certain extent. Therefore, in the embodiment of the application, when the wind pressure information of the target vehicle is obtained, the wind pressure information of the target vehicle can be obtained according to the preset time interval.
S102: and determining the number of times of wind blowing of an air compressor of the target vehicle according to the wind pressure information of the target vehicle.
It should be noted that, in practical applications, when the wind pressure of the vehicle is greater than or equal to a certain threshold value and the wind pressure is in an ascending trend, it indicates that the air compressor has a wind blowing phenomenon. In the embodiment of the application, when the wind pressure of the target vehicle is greater than or equal to the preset wind pressure threshold value and the wind pressure of the target vehicle is in an ascending trend, it is determined that the air compressor of the target vehicle blows once. For example, the preset wind pressure threshold value is 700kpa (english: kpa), and if the wind pressure of the target vehicle rises from 700kpa to 750kpa from time t1 to time t2, it is determined that the air compressor of the target vehicle divides once, where time t1 and time t2 may be two adjacent wind pressure information sampling points.
S103: and determining a corresponding threshold value of the number of times of wind according to the train number information and the model information of the target vehicle.
Considering that the number of times of wind blowing of the air compressor of the vehicle is related to the traffic route traveled by the vehicle and the model of the vehicle, in the embodiment of the present application, the threshold value of the number of times of wind blowing corresponding to the target vehicle may be determined based on the traffic route traveled by the target vehicle and the model of the target vehicle.
The embodiment of the present application does not specifically limit the specific implementation manner of S103, and as an example, a mapping relationship between the train number information, the model number information, and the threshold value of the number of times of wind blowing may be established in advance. Specifically, the wind number threshold is used to indicate a wind number upper limit corresponding to the vehicle number information and the model information when the vehicle travels.
In the embodiment of the application, the mapping relationship can be established by obtaining a large number of data samples, wherein one group of data samples is the corresponding wind blowing times when a vehicle of a certain model runs on a cross road corresponding to a certain train number and a wind supply system does not have a fault. In the embodiment of the present application, the data samples may be obtained from a big data platform storing wind pressure information corresponding to vehicles on each intersection.
For ease of understanding, the mapping relationship is described below in conjunction with table 1.
It should be noted that table 1 is shown only for convenience of understanding, and does not limit the embodiments of the present application.
TABLE 1
| Train number letterInformation processing device | Model information | Threshold value of wind blowing times |
| G101 | Harmonious horn | 10 |
| D101 | Fuxing number | 12 |
| G102 | Harmonious horn | 11 |
After the mapping relationship is established, the mapping relationship may be utilized to determine that the number information is equal to the number information of the target vehicle, and the model information is equal to the wind-blowing frequency threshold corresponding to the model information of the target vehicle, as the wind-blowing frequency threshold corresponding to the target vehicle.
Of course, S103 may also be implemented in other manners, for example, a specific wind-up number determination algorithm may be adopted to calculate the wind-up number corresponding to the target vehicle, which is not described herein again.
It should be noted that the execution order of S102 and S103 is not specifically limited in the embodiment of the present application, and S102 may be executed after S103 or S102 may be executed simultaneously with S103, in addition to S102 may be executed before S103.
S104: and if the wind blowing times of the air compressor of the target vehicle are larger than the wind blowing time threshold value, determining that the wind supply system of the target vehicle is in fault.
In the embodiment of the present application, it is considered that in practical applications, if the air supply system of the vehicle does not malfunction, the number of times of wind blowing is generally not too large. In other words, the greater the number of wind blows, the greater the likelihood of failure of the wind supply system of the target vehicle. As described above, the threshold value of the number of times of wind is used to indicate the upper limit of the number of times of wind when the vehicle corresponding to the number of times of vehicle information and the model information travels. In other words, the threshold value of the number of times of wind blowing corresponding to the target vehicle represents an upper limit of the number of times of wind blowing corresponding to the target vehicle when the target vehicle travels on the traffic road corresponding to the vehicle number information of the target vehicle. And if the number of times of wind blowing corresponding to the target vehicle exceeds the threshold value of the number of times of wind blowing corresponding to the target vehicle, indicating that the wind supply system of the target vehicle has a fault. Correspondingly, if the number of times of wind blowing corresponding to the target vehicle does not exceed the threshold value of the number of times of wind blowing corresponding to the target vehicle, it is indicated that the wind supply system of the target vehicle is not in fault.
In an implementation manner of the embodiment of the application, when it is determined that the air supply system of the target vehicle has a fault, the terminal device may further display fault prompt information to prompt a maintenance worker to timely overhaul the air supply system of the target vehicle.
As can be seen from the above description, in the embodiment of the present application, in consideration that the number of times of wind blowing of the air compressor during the running of the vehicle may indicate whether the air supply system of the vehicle has a fault, in the embodiment of the present application, when determining whether the air supply system of the target vehicle has a fault, the number of times of wind blowing of the air compressor of the target vehicle may be determined. In addition, considering that the number of times of wind blowing of the air compressor of the vehicle is related to the traffic route traveled by the vehicle and the model of the vehicle, in the embodiment of the present application, the threshold value of the number of times of wind blowing corresponding to the target vehicle may be determined based on the traffic route traveled by the target vehicle and the model of the target vehicle. And determining whether the air supply system of the target vehicle has a fault or not by comparing the wind-blowing frequency threshold value with the wind-blowing frequency of the air compressor of the target vehicle. Specifically, the number information, the model information, and the wind pressure information of the target vehicle may be acquired. The vehicle information may represent the road crossing traveled by the target vehicle. Then, determining the number of times of wind blowing of an air compressor of the target vehicle according to the wind pressure information of the target vehicle; determining a corresponding wind-up frequency threshold according to the train number information and the model information of the target vehicle; and if the wind blowing times of the air compressor of the target vehicle are larger than the wind blowing time threshold value, determining that the wind supply system of the target vehicle is in fault. Since the aforementioned threshold value of the number of times of wind is determined based on the number information and the model information of the target vehicle, that is, matched with the traffic traveled by the target vehicle and the information of the target vehicle itself. Therefore, by the scheme provided by the embodiment of the application, whether the air supply system of the target vehicle has a fault or not can be accurately determined.
In one implementation of the embodiment of the present application, it is considered that in practical applications, a corresponding instrument may be used to determine whether an air compressor of a vehicle has failed. In the embodiment of the present application, if the air compressor of the target vehicle fails, the foregoing steps S101 to S104 may not be executed any more, because it can be determined that the air supply system of the target vehicle fails by the failure of the air compressor. The aforementioned S101-S104 are performed to determine whether the air supply system of the target vehicle has failed only when it is otherwise determined that the air compressor of the target vehicle has not failed. Specifically, in the embodiment of the present application, fault information of an air compressor of the target vehicle may be acquired, where the fault information of the air compressor of the target vehicle is used to indicate whether the air compressor of the target vehicle is faulty or not. If the failure information indicates that the air compressor of the target vehicle is not failed, the foregoing step S101 and subsequent steps are executed.
The embodiment of the present application does not specifically limit a specific implementation manner of obtaining the fault information of the air compressor of the target vehicle, and as an example, the fault information of the air compressor of the target vehicle may be obtained by reading a fault code of the air compressor.
It will be appreciated that in practice the behaviour of the vehicle during travel is different from the behaviour of the vehicle when it is stationary. As described above, the embodiments of the present application provide a solution for determining whether a failure occurs in a wind supply system during a vehicle traveling. In view of this, in the embodiment of the present application, the speed of the target vehicle may also be acquired, and whether the vehicle is in the process of traveling is determined according to the speed of the target vehicle. The foregoing steps S101 to S104 are only performed when it is determined that the vehicle is in the process of traveling, otherwise, the foregoing steps S101 to S104 may not be performed. Specifically, when the speed of the target vehicle is greater than zero, it may be determined that the vehicle is in the process of traveling, and the foregoing step S101 and subsequent steps are performed accordingly.
The embodiment of the present application does not specifically limit an implementation manner of obtaining the speed of the vehicle, and it can be understood that a speed measuring device is provided on a general vehicle.
It is understood that, in practical applications, if the vehicle is abnormally driven, the usage situation of the vehicle during driving is different from the usage situation when the vehicle is normally driven. For example, when the vehicle is late, the passenger in the vehicle uses the toilet, which requires wind, differently from when the passenger is driving right, and thus, the vehicle is driven late and right. The difference in wind usage due to the abnormal running of the vehicle does not indicate that the air supply system of the vehicle is in failure.
In view of this, in the embodiment of the present application, the result of whether or not an abnormality occurs in the air supply system of the target vehicle, which is obtained by executing the foregoing S101 to S104, is accurate. The aforementioned S101-S104 may be executed only when it is determined that the target vehicle has no travel abnormality, and the aforementioned S101-S104 may not be executed any more when it is determined that the target vehicle has a travel abnormality.
Specifically, in the embodiment of the present application, the position information of the target vehicle may be acquired; determining a driving route of the target vehicle according to the number of the target vehicle; determining whether the target vehicle has abnormal running or not according to the position information of the target vehicle and the running route of the target vehicle; if the target vehicle has no abnormal driving, the aforementioned step S101 and the following steps are executed. If the target vehicle has abnormal running, the step S101 and the subsequent steps are not executed.
Note that the target vehicle travel abnormality mentioned here may be, for example, occurrence of late of the target vehicle.
In the embodiment of the present application, the position information of the target vehicle may be determined by using a Positioning device such as a Global Positioning System (GPS).
It can be understood that, in practical applications, the number of vehicles and the driving route are in one-to-one correspondence, and therefore, according to the information of the number of vehicles of the target vehicle, the driving route corresponding to the target vehicle can be determined. The driving route comprises a station where the vehicle passes in the driving process and a corresponding moment when the vehicle passes the station.
In the embodiment of the application, whether the position of the target vehicle is consistent with the target position or not can be determined by combining the position information of the target vehicle and the driving route. And the target position is the position of the target vehicle indicated by the driving route. And if the position of the target vehicle is not consistent with the target position, the target vehicle is indicated to be abnormal in running. For example, it is determined that the target vehicle passes through the station 1, the station 2 and the station 3 during the driving process according to the train number information of the target vehicle, and the position information of the target vehicle indicates that the target vehicle is located at the station 2, but it is determined that the target vehicle should be located at the station 3 based on the driving route, and it may be determined that the target vehicle is late, that is, the target vehicle has a driving abnormality. For this case, the aforementioned S101 and subsequent steps may not be executed any more.
