[0047] Embodiment 1

[0048] In view of the gradual popularization of new energy vehicles, the scheduled charging function has become an important function of new energy electric vehicles. When the scheduled charging event of the car adopts multiplexing technology, the current bench simulation of the real car single-channel CAN communication is not enough to meet the test requirements, and can only transmit information on a certain channel. Complex multiplexing communication can only be tested on the real car. Real car resources are limited, and it is difficult for real cars to meet unconventional tests such as failure and destructiveness. Therefore, it is urgent to develop a test method for scheduled charging events using multiplexing technology. This test method embodiment provides a test method for scheduled charging events of on-board multimedia. The test method realizes that the scheduled charging information is sent to the on-board multimedia in an orderly and periodic manner through programming, and inserts information data as required when adding events, replaces information data in a targeted manner when editing events, and logically reorganizes data when deleting events. It only needs to enter the new, edited, and deleted information on the panel and perform the corresponding operations, which covers the test requirements more comprehensively, simplifies the test environment to a greater extent, and completes related tests more quickly.

[0049] For details, please refer to the following Figure 1-2 ,in, Figure 1 The structural flow chart of the vehicle multimedia scheduled charging event test method in this embodiment is shown; Figure 2 The structural block diagram of the testing method of this embodiment is shown.

[0050] In this embodiment, the vehicle multimedia scheduled charging event test method is specifically applied to the vehicle multimedia scheduled charging event test system, which is used to test the scheduled charging function of new energy electric vehicles. Specifically, the system includes a host computer and a vehicle multimedia, and a processor is provided in the host computer. The processor is equipped with a labview processing program. After adding, editing or deleting the scheduled charging event through the labview processing program, the test method integrates multiple signals into a single message and then sends it to the vehicle multimedia. Specifically, the vehicle multimedia scheduled charging event test method of this embodiment includes:

[0051] 101. Establish a charging event information database.

[0052] 102. When a charging event processing action is monitored, it is determined in sequence whether an adding, editing or deleting charging event occurs.

[0053] 103. If yes, insert, replace or delete the corresponding data bit of the charging event information library according to the index of adding, editing or deleting the charging event.

[0054] 104. After calculating and reorganizing the charging event information database, a single-channel message signal is obtained by processing and calculating, and sent to the vehicle-mounted multimedia.

[0055] The test method in this embodiment is mainly used to simplify the manual assignment of multiplexed messages one by one, which can more accurately ensure that each channel of data is orderly and sent in accordance with the demand cycle, and is more in line with the actual vehicle environment. Among them, this test method establishes a charging event information library, and then updates the information library according to the event change action, and finally assigns the updated information library to a single-channel message and sends it.

[0056] As described in step 103, the charging event information library inserts, replaces or deletes the corresponding data bits of the charging event information library according to the index of adding, editing or deleting the charging event. The specific operation method is as follows:

[0057] In the judgment domain, first determine whether the current action is to add a charging event. If the current action is to add a charging event, obtain the analysis data of the charging event information library, and perform programming calculations on the data. According to the calculation results, index the insertion interface of the newly added charging event, and then insert the information of the newly added charging event into the charging event information library through the interface. At the same time, calculate the sending counter and update the sending counter. Then, calculate and reorganize the data inserted into the charging event information library. The reorganized information library replaces the charging event information library before the data is inserted.

[0058] If the current event is not an increase in charging, the next step is to determine whether there is an edited charging event. If so, the analysis data of the charging event information library is obtained, and the data is programmed and calculated. According to the calculation results, all data bits of the charging event information that need to be edited are indexed, and the new information replaces the old information of the original data bit according to the data bit. At the same time, the sending counter is calculated and updated, and then the information library of the replaced data is replaced with the charging event information library before the edited data.

[0059] If the current charging event is not editable, the next step is to determine whether there is a charging event to be deleted. If so, the analysis data of the charging event information library is obtained, and the data is programmed and calculated. According to the calculation result, all data bits of the charging event information that need to be deleted are indexed, and the information that needs to be deleted is deleted according to the data bit. At the same time, the sending counter is calculated and updated. Then, the information library after the information is deleted is calculated and reorganized according to the rules. The reorganized information library replaces the charging event information library before the data is deleted.

[0060] Of course, there are also situations where when the charging event processing action is monitored, it is judged that no charging event has been added, edited or deleted. In this case, if no charging event has been added, edited or deleted, the judgment domain is jumped out, and the capacity of the current charging event information library is calculated to obtain the capacity value. Composite calculations are performed based on the capacity value and the data sending counter to obtain the index of each charging event. According to the timer set by the program, the single charging event information data is extracted periodically and orderly, and then the signal bit field of each message corresponding to each part of the information data is assigned to each signal of each message, and finally the data is sent to the vehicle multimedia according to the required multiplexed message sending rules. The dotted box part in the flow chart is periodic operation, and the other parts are event operation.

[0061] Specifically, the determination fields in the above content are used to determine in sequence whether there is a process of adding, editing or deleting a charging event.

[0064] When monitoring the charging event processing action, determine whether it is the first time to run the program;

[0065] If yes, initialize the charging event data, initialize the data sending counter, and then enter the judgment domain;

[0066] If not, directly enter the judgment domain; in the judgment domain, the processor determines in sequence whether there is an add, edit or delete charging event.

[0067] The specific steps are: when running the program, determine whether it is the first time to run, if it is the first time to run, initialize the data of the charging information library and the data transmission counter, and enter the judgment domain of the program after the initialization is completed. If it is not the first time to run, directly enter the judgment domain of the program.

[0068] The step of the processor determining in sequence whether an add, edit or delete charging event occurs specifically includes:

[0069] In the determination domain, determine whether the current action is to add a charging event, and if so, perform an operation to add a charging event;

[0070] If the current action is not to add a charging event, determine whether the current action is to edit a charging event. If so, perform an operation to add a charging event.

[0071] If the current action is not to edit the charging event, determine whether the current action is to delete the charging event.

[0072] In some embodiments, the step of inserting, replacing or deleting the corresponding data bit of the charging event information library according to adding, editing or deleting the index of the charging event specifically includes:

[0073] If the current action is to add a charging event, obtain the analysis data of the charging event information library, and insert the newly added charging event information into the charging event information library through the interface according to the index;

[0074] If the current action is to edit the charging event, obtain the analysis data of the charging event information library, and replace the charging event information library before editing the data with the new information according to the data bit based on the index;

[0075] If the current action is to delete the charging event, the analysis data of the charging event information library is obtained, and the information to be deleted is deleted according to the index and the data bit, and the charging event information library before the deletion of the data is replaced.

[0076] In some embodiments, after calculating and reorganizing the charging event information base, the step of processing and calculating to obtain a single-channel message signal and sending it to the vehicle-mounted multimedia specifically includes:

[0077] Extract the updated charging information base according to the index and the timer, aggregate it into a single charging event information data, and perform compound calculation on the updated charging information base through the data sending timer;

[0078] The final value is assigned to obtain a single-channel message signal;

[0079] Send a single-channel message signal to the vehicle multimedia.

[0080] In some embodiments, the step of inserting, replacing or deleting the corresponding data bit of the charging event information library according to adding, editing or deleting the index of the charging event specifically includes:

[0081] After adding, editing or deleting a charging event, obtain the analysis data of the charging event information library and perform programmatic calculations on the data;

[0082] Insert, replace or delete the corresponding data bit of the charging event information library according to the index of adding, editing or deleting the charging event;

[0083] Calculate and update the sending counter, and reorganize the inserted, replaced or deleted data information;

[0084] Charging event information library before replacing data.

[0085] The advantage of this embodiment is that this test method realizes the orderly and periodic sending of the scheduled charging information to the on-board multimedia through programming, inserts information data as required when adding events, replaces information data in a targeted manner when editing events, and logically reorganizes data when deleting events, and then enables the sending of the modified information library.
