In addition, considering that if the TIAS performs parameter reading of the corresponding train in advance, it may be determined whether the train parameter needs to be adjusted, if it is determined that adjustment is not needed, unnecessary parameter adjustment may be avoided, and if it is determined that adjustment is needed, a specific parameter that needs to be modified by the train may be found, so in the embodiment of the present invention, a preset adjustment frame structure configured to generate a parameter adjustment frame may include a command identification bit, where the command identification bit may indicate a command type of the corresponding parameter adjustment frame, and the command type herein may be, for example, parameter adjustment, parameter non-adjustment, parameter reading, and the like.

In order to solve the problem, the embodiment of the invention sets the target VOBC to return an adjustment feedback frame to the TIAS, where the adjustment feedback frame includes an adjustment execution state for the adjustment information of the target parameter, where the adjustment execution state includes that the adjustment is successful, that the adjustment is unsuccessful, and that the adjustment is in progress.

The new parameter adjustment frame may be generated by directly inputting new target parameter adjustment information, generating a new parameter adjustment frame based on the new target parameter adjustment information, or by checking the target parameter adjustment information, determining an abnormal parameter therein, modifying the parameter to obtain new target parameter adjustment information, and generating a new parameter adjustment frame based on the new target parameter adjustment information.

Based on any one of the above embodiments, the embodiment of the present invention provides a method for adjusting train parameters, and fig. 2 is a second schematic flow chart of the method for adjusting train parameters provided by the present invention, as shown in fig. 2, the method is applied to a vehicle-mounted control system VOBC, and the method includes:

Step 210, receiving a parameter adjustment frame broadcasted by a vehicle integrated automation system TIAS, wherein the parameter adjustment frame is generated by the TIAS based on target parameter adjustment information input by a user, and the target parameter adjustment information comprises a target train identifier, a target parameter identifier and a target parameter value;

Step 220, if the target train identifier is the train identifier of the train to which the VOBC at the home terminal belongs, performing parameter adjustment based on the parameter adjustment frame.

And the TIAS broadcasts a parameter adjustment frame to the VOBC of each train, and after any VOBC receives the parameter adjustment frame, if the target train identification corresponding to the parameter adjustment frame is exactly the train identification of the train to which the local end VOBC belongs, the TIAS can adjust the train parameters according to the parameter adjustment frame, otherwise, no operation is needed. After the train identification correspondence is determined, the VOBC at the home end may directly adjust the train parameters according to the parameter adjustment frame, or may first check the parameter adjustment frame, and then adjust the train parameters after the check is passed.

The TIAS receives target parameter adjustment information input by a user, and generates a parameter adjustment frame according to the target parameter adjustment information. The target parameter adjustment information may include a target train identification, a target parameter identification, and a target parameter value, which may be input by a user through an intelligent terminal.

According to the method provided by the embodiment of the invention, the TIAS broadcasts the parameter adjustment frame to the VOBC of the vehicle-mounted control system, and the local VOBC carries out parameter adjustment based on the parameter adjustment frame, so that the remote modification of the parameters of the VOBC vehicle-mounted equipment on the train is realized, the aim of greatly reducing the investment of manpower and time cost is further fulfilled, the efficiency of modifying the parameters of the train is greatly improved, the batch adjustment of the parameters of the vehicle-mounted equipment of a plurality of trains can be realized, and the problem that only the parameters of the vehicle-mounted equipment of a single train can be modified by a single person in the prior art is solved.

On the basis, when the target train identifier corresponding to the parameter adjustment frame broadcasted by the tia s is exactly the train identifier of the train to which the local VOBC belongs, the local VOBC may first determine whether parameter adjustment based on the parameter adjustment frame is required according to the command valid bit and/or the command identifier bit, for example, when the command valid bit indicates that the parameter adjustment frame is invalid, or when the command type indicated by the command identifier bit is not adjusted, the local VOBC may not need to perform parameter adjustment operation.

Based on any of the above embodiments, step 220 further comprises:

and sending an adjustment feedback frame to the TIAS, wherein the adjustment feedback frame comprises an adjustment execution state aiming at the target parameter adjustment information, and the adjustment execution state comprises successful adjustment, unsuccessful adjustment and adjustment.

In order to solve the problem, the embodiment of the invention sets the local terminal VOBC to return an adjustment feedback frame to the TIAS, wherein the adjustment feedback frame includes an adjustment execution state aiming at the target parameter adjustment information, the adjustment execution state includes that the adjustment is successful, the adjustment is unsuccessful and the adjustment is in progress, on the basis, after the TIAS receives the adjustment feedback frame, corresponding processing can be performed in time according to the adjustment feedback frame, for example, when the adjustment execution state is that the adjustment is unsuccessful, a new parameter adjustment frame can be regenerated and sent to the local terminal VOBC, so that the accuracy of parameter adjustment is ensured.

The new parameter adjustment frame may be generated by directly inputting new target parameter adjustment information, generating a new parameter adjustment frame based on the new target parameter adjustment information, or by first checking the target parameter adjustment information, determining an abnormal parameter therein, then modifying the parameter to obtain new target parameter adjustment information, and generating a new parameter adjustment frame based on the new target parameter adjustment information.

According to the method provided by the embodiment of the invention, the state feedback is carried out through the local VOBC so as to enable the TIAS to automatically adjust the target parameter adjustment information, manual operation is not needed in the whole process, the input of manpower is greatly reduced, the accuracy of the parameter adjustment frame issued by the TIAS system is ensured, and meanwhile, the problem of operation errors caused by manual parameter adjustment is avoided.
