Disclosed in the embodiment of the present application in technical solution, when the data arrived are Full Vehicle Dynamics operation data, obtain To the Full Vehicle Dynamics parameter in may include the railway freight train transverse acceleration and vertical acceleration, pass through The variation of the transverse acceleration and vertical acceleration may determine that train whether misoperation.
When needing to obtain the vehicle kinetic parameter of railway freight train, can require according to GB/T5599-1985 described (on the inside of sleeper beam, away from bogie pivot center 1000mm or so), installation has wireless transmission function on the car body central sill of railway freight train Vibrating sensor, the vibrating sensor may include vertical and lateral accelerometer, by described vertical and laterally accelerate The vibration performance parameter of train being calculated is spent, when detecting that the transverse acceleration is greater than the first preset value or longitudinal adds It is to show that the railway freight train driving is abnormal that speed, which is greater than the second preset value, the technical side disclosed in the embodiment of the present application In case, first preset value is a preset value no more than 0.5g, and second preset value is no more than one of 0.7g Preset value.
Step S103: the operation data in the railway freight train appearance abnormal period is extracted;
When detecting train operation misoperation, the operation number by getting monitoring the abnormal moment later is acquired According to using these parameters as the failure operation data of train.
Step S104: the operation data in the abnormal period is sent to ground data central server;
In the present solution, ground data central server is used to work as inspection to railway freight train offer technical support When measuring train and misoperation occur, the failure operation data of train are sent to the ground data central server, by institute Ground data central server is stated to determine the fault type of train and provide solution.
In the present solution, the ground data central server can determine the failure of train by way of data comparison Type, specifically, being prestored at train when operation data is Full Vehicle Dynamics parameter in the ground data central server The typical unusual waveforms of how corresponding integral power parameter when various failure operations, the integral power parameter are obtaining To train failure operation data when, corresponding with abnormal data integral power Parameters variation curve graph is generated, by institute It states integral power Parameters variation curve graph to compare with the typical unusual waveforms prestored, finds and join with the integral power The highest typical unusual waveforms of number change curve similarity, obtain the corresponding fault type of typical case's unusual waveforms, by the event Hinder current failure type of the type as train, then by transferring the solution for the fault type in database, will transfer To solution fed back as default solution.
The ground data central server is when providing feedback data to train end, when detecting that train is in station, By local area network in standing to train end feedback data, when train, which is located at, stands outer, by public network to train feedback data, certainly, Disclosed in the embodiment of the present application in technical solution, directly the ground data central server can also be arranged in class vehicle On, it can directly be communicated at this time by WIFI or public network with the ground data central server;
In this step, understand the history data of train, in order to facilitate ground data central server so as to column The operation conditions of vehicle is analyzed,, can be with when detecting that train enters the station disclosed in the embodiment of the present application in technical solution All data parameters of collected train in vehicle hour section are sent into the ground number by local area network in standing According to central server.
Step S105: the default solution that the ground data central server is sent is obtained;
Step S106: the default solution is sent to the control platform of the railway freight train.
It gets when ground data central server analyzes the solution for abnormal data, sends it to column When the control platform of the control platform of vehicle, the train obtains feedback data, train is controlled according to feedback data, thus Solve operation troubles.
By technical solution disclosed in the above embodiments of the present application as it can be seen that acquiring in real time and detecting railway freight train operation Abnormal data is sent to ground number when determining vehicle abnormality operation according to the operating parameter by operating parameter in the process According to central server, and the solution of the ground data central server feedback is obtained, solution is sent to train Control platform, to ensure that the safe operation of train.
5T system is a kind of advanced train monitoring system with many years, is successfully provided for the safety of railway freight Powerful support, but ground is arranged in the 5T system, and is to be monitored by the way of interrupted to locomotive, if machine Vehicle goes wrong between two monitoring points, this system is just monitored less than therefore, to improve monitoring accuracy, reducing operation Risk sets up continuous monitor system with regard to very necessary in the possible situation of condition.
Therefore, disclosed in the embodiment of the present application in technical solution, the above method can be applied to train end, and train end can Data interaction is carried out with ground data central server in a manner of using public network communication or wireless Network Communication, is disclosed in the application Technical solution in, can according to the position of the train select and the ground data central server between data transmit Mode, specifically, referring to fig. 2, in above scheme, the integral power parameter is sent to ground data central server, It can specifically include:
Step S201: judging whether the railway freight train enters the station, if so, executing step S202, otherwise executes step Rapid S203;
Step S202: the railway freight train is occurred to the operation in the period of exception by local area network in standing Parameter is sent to ground data central server;
Step S203: the operating parameter railway freight train occur by public network in the period of exception is sent out Give ground data central server.
In the present solution, when train is in that station is outer, train occurs abnormal, by wireless public network with it is genuinely convinced in ground data Business device, when train, which is in interior, train of standing, exception occurs, by standing between interior local area network and the ground data central server Data interaction is carried out, the real time monitoring to train operating conditions is realized, ensure that the safe operation of the railway freight train.
During train operation, the factor for causing train to break down may be by a variety of, in addition to the factor of train itself It will lead to except train fault operation, extraneous factor is also possible to that train fault is caused to run, therefore, in order to facilitate operation maintenance personnel The basic reason that investigation causes train fault to run, in above scheme, it is also necessary to which record is when monitoring that misoperation occurs in train When train locating for geographical location, collected geographical location is also sent to the ground data central server.
Certainly the geographical location information that train can also be acquired in real time in this programme, establish the geographical location information with There is railway freight train different when detecting train misoperation in mapping relations between the integral power parameter The operating parameter and corresponding geographical location information in the normal period are sent to the ground data central server, That is, after determining that being operating abnormally occurs in the railway freight train, can also include: in the above method
It obtains and the corresponding railway freight train of the operating parameter in abnormal time section occurs with railway freight train Coordinate data;
The coordinate data is bound and synchronous with the operating parameter;
The coordinate data is sent to the ground data central server.
