According to the above module structure, various embodiments of the method of the present invention are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the present invention, where the method for changing the vehicle communication protocol includes:
step S100, when the software of the vehicle is upgraded successfully, acquiring parameter information of the vehicle, wherein the parameter information comprises a vehicle identification code and a current software version number corresponding to the software;
the method for changing the vehicle communication protocol is applied to a remote monitoring platform, the remote monitoring platform is mainly used for collecting and monitoring the working condition data of the vehicle in real time, when the vehicle breaks down or encounters dangerous conditions, the vehicle early warning information is timely and effectively sent to a background and a management user through real-time working condition detection, the potential safety hazard of vehicle operation is effectively eliminated, and meanwhile, data support can be provided for follow-up fault maintenance and optimization of the vehicle.
In one embodiment, when the vehicle-mounted terminal software of the vehicle is successfully upgraded by the remote upgrade platform, the vehicle uploads the vehicle identification code and the current software version number corresponding to the software to the remote upgrade platform, and then the remote upgrade platform pushes the vehicle identification code and the current software version number corresponding to the software to the remote monitoring platform, so that the remote monitoring platform obtains the parameter information of the vehicle, wherein the remote upgrade platform is a supplier-facing technical platform and is mainly used for upgrading and updating the vehicle-mounted terminal software of the vehicle.
The vehicle Identification code, abbreviated as vin (vehicle Identification number), is unique Identification information of the vehicle. The software version number is a software version number of the vehicle-mounted terminal, and a person skilled in the art can know that when software of the vehicle-mounted terminal is successfully upgraded through the remote upgrade platform, the current software version number of the vehicle-mounted terminal is also updated accordingly.
Step S200, determining a communication protocol corresponding to the current software version number in a preset upgrading information database;
the upgrade information database is a mapping relationship between each software version number and each corresponding communication protocol, which is pre-stored by a person skilled in the art. When new software needs to be updated in the remote upgrade platform, a person skilled in the art needs to add the software version number of the online software and a corresponding communication protocol in the upgrade information database in advance.
It can be understood that when the remote monitoring platform monitors that the collected data item of the vehicle-mounted terminal is changed, for example, the maximum discharge voltage of the power battery is increased, or the maximum charging current of the power battery is modified from 1A to 2A, or the detection of the rotating speed of the driving motor of the vehicle is cancelled, and the like, the software version of the vehicle-mounted terminal needs to be upgraded through the remote upgrading platform. After the software version is upgraded successfully, the communication protocol message signal collected by the CAN bus of the whole vehicle is changed. When the communication protocol of the CAN bus of the vehicle for collecting messages changes, the communication protocol of the remote monitoring platform interacting with the vehicle may be updated accordingly. After the vehicle-mounted terminal software of the vehicle is successfully upgraded, the communication protocol is determined to be the communication protocol for the interaction between the remote monitoring platform and the vehicle through the step S200.
It should be noted that, further, step S200 includes, before:
in one embodiment:
acquiring a communication protocol which is determined by a developer according to a first communication matrix and corresponds to the software version number, wherein the first communication matrix is determined by the developer according to the direction of a collected data item of a vehicle, which needs to be changed;
and adding the corresponding relation between the current software version number and the communication protocol into the upgrading information database so as to update the upgrading information database.
The method comprises the steps of obtaining a communication protocol which is determined by a developer according to a first communication matrix and corresponds to a software version number, presetting a corresponding relation between the software version number and the communication protocol on a remote monitoring platform, and further realizing that the communication protocol corresponding to the software version number can be automatically matched in an upgrade information database of the remote monitoring platform when vehicle-mounted terminal software of a vehicle is upgraded successfully in the follow-up process, so that the vehicle and the remote monitoring platform can be automatically updated in an interactive communication protocol.
In another embodiment:
acquiring a collected data item required to be changed by a vehicle, and determining a communication protocol corresponding to a software version number according to the changed collected data item;
in this embodiment, the remote monitoring platform may automatically generate a communication matrix corresponding to the changed acquired data item by obtaining the acquired data item that needs to be changed and input by the developer, and then determine the communication protocol and the current software version number according to the communication matrix.
And adding the corresponding relation between the current software version number and the communication protocol into the upgrading information database so as to update the upgrading information database.
It CAN be understood that, in practical application, a communication protocol for communicating a vehicle with a remote monitoring platform often changes due to changes of vehicle collected data items, the changes of the vehicle collected data items CAN cause increase and decrease of a whole vehicle collected message or modification of some message signals, and the communication protocol for collecting the message by a whole vehicle CAN bus is manufactured according to a communication matrix. The communication matrix is a CAN communication matrix (CAN communication matrix), and each node in the vehicle network CAN complete information interaction and sharing only by following the communication matrix.
And updating the upgrade information database in real time by adding the corresponding relation between the current software version number and the communication protocol into the upgrade information database.
After the step S200, executing the step S300, updating the original communication protocol of the vehicle corresponding to the vehicle identification code in the preset communication information database to the communication protocol corresponding to the current software version number, and interacting with the vehicle by using the new communication protocol.
For ease of understanding, an embodiment is presented to aid understanding: and after the vehicle-mounted terminal software version of the vehicle is successfully upgraded by the remote upgrading platform, the vehicle uploads the current software version number and the vehicle identification code of the vehicle-mounted terminal to the remote upgrading platform. And the remote upgrading platform receives the current software version number and the vehicle identification code and pushes the current software version number and the vehicle identification code to the remote data monitoring platform through the interface. The remote data monitoring platform is configured with a communication protocol corresponding to the current software version number in advance in the upgrading information database, and when the remote data monitoring platform receives the current software version number pushed by the remote monitoring door platform, the communication protocol corresponding to the current software version number is determined in the upgrading information database, so that the communication protocol for interaction between the vehicle corresponding to the vehicle identification code and the remote data monitoring platform is automatically updated. In another embodiment, after the vehicle-mounted terminal software version of the vehicle is successfully upgraded for the remote upgrade platform, the vehicle directly uploads the current software version number of the vehicle-mounted terminal and the vehicle identification code to the remote monitoring platform, the remote data monitoring platform has configured a communication protocol corresponding to the current software version number in the upgrade information database in advance, and when the remote data monitoring platform receives the current software version number pushed by the remote monitoring door platform, the communication protocol corresponding to the current software version number is determined in the upgrade information database, so that the communication protocol for interaction between the vehicle corresponding to the vehicle identification code and the remote data monitoring platform is automatically updated.
In the embodiment, the vehicle identification code of the vehicle and the software version number of the vehicle-mounted terminal after the software upgrading is successful are obtained through the step of obtaining the parameter information of the vehicle when the software upgrading of the vehicle is successful. And matching a communication protocol for communicating with the vehicle corresponding to the vehicle identification code by determining the communication protocol corresponding to the current software version number in an upgrade information database, updating the original communication protocol of the vehicle corresponding to the vehicle identification code in a preset communication information database to be the communication protocol corresponding to the current software version number, and finishing automatic change of the vehicle communication protocol by adopting the step of interaction between the new communication protocol and the vehicle. According to the embodiment, the vehicle parameters are acquired to judge whether the current vehicle needs to change the communication protocol between the remote monitoring platform and the vehicle, so that the communication protocol for interaction between the vehicle and the remote monitoring platform is further automatically updated, the communication protocol associated with the vehicle-mounted terminal does not need to be manually changed, normal data communication between the vehicle and the remote monitoring platform is guaranteed, and convenience and accuracy for changing the communication protocol are improved.
Further, referring to fig. 3, fig. 3 is a partial schematic flow chart of a second embodiment of the present invention, and based on the first embodiment, the step S200 includes:
step S400, checking whether the parameter information is correct;
and checking whether the parameter information is correct or not through a preset mode, wherein the preset mode can be set by a person skilled in the art according to the actual condition so as to better check whether the parameter information meets the requirements or not. For example, the current software version number is checked for the presence in the upgrade information database and/or the vehicle identification code is checked for the presence in the communication information database. The communication information database is a database in the remote monitoring platform, and the database has a mapping relation between each vehicle identification code mapping corresponding communication protocol and each corresponding software version number. It is to be understood that the upgrade information database and the communication information database are different databases.
Further, the step S400 includes: checking whether the vehicle identification code exists in the communication information database;
if the vehicle identification code exists in the communication information database, checking whether the current software version number exists in the upgrading information database;
and if the current software version number exists in the upgrading information database, determining that the parameter information is verified correctly.
As described above, the communication information database has a mapping relationship between each vehicle identification code mapping corresponding communication protocol and each corresponding software version number, and the upgrade information database and the communication information database are different databases.
It can be understood that, the checking process of checking whether the vehicle identification code exists in the communication information database and the checking process of checking whether the current software version number exists in the upgrade information database are performed at the same time, and the sequence of the two checking processes is not limited, preferably.
Further, the parameter information further includes a current ICCID identification code (integrated circuit card identification code), and the step of determining that the parameter information is correctly verified if the current software version number exists in the upgrade information database further includes:
if the current software version number exists in the upgrading information database, checking whether the current ICCID identification code consists of characters with preset digits;
wherein, the preset digit is preset by the technical personnel in the field, and it can be known that the ICCID identification code generally consists of 20-bit characters, and the technical personnel in the field can preset the preset digit to 20 bits, at this moment: checking whether the current ICCID identification code is composed of 20-digit characters.
If the current ICCID identification code consists of characters with preset digits, checking whether the ICCID identification code corresponding to the vehicle identification code in the upgrade information database is the current ICCID identification code;
the vehicle identification code is a unique vehicle identification code, and the vehicle identification code is a unique vehicle identification code. When the fact that the preset ICCID corresponding to the vehicle identification code in the upgrading information database is not the ICCID is detected, the fact that the acquired parameter information of the vehicle is wrong can be determined, and at the moment, the remote monitoring platform or the interactive equipment interacting with the remote monitoring platform reports the error so as to wait for an engineer to confirm and take further solution measures.
And if the ICCID corresponding to the vehicle identification code in the upgrade information database is the current ICCID, the parameter information is verified correctly.
And if the vehicle identification code does not exist in the communication information database, or the current software version number does not exist in the upgrading information database, or the ICCID identification code does not consist of characters with preset digits, or the preset ICCID identification code corresponding to the vehicle identification code in the upgrading information database is not the current ICCID identification code, the parameter information is checked to be wrong.
Similarly, the vehicle identification code is checked whether to exist in a communication information database, the current software version number is checked whether to exist in an upgrading information database, the ICCID identification code is checked whether to consist of characters with preset digits, and the preset ICCID identification code corresponding to the vehicle identification code in the upgrading information database is checked whether to be the current ICCID identification code. It is understood that, preferably, the verification process of verifying whether the ICCID identification code is composed of characters of a preset number of digits precedes the verification process of verifying whether the preset ICCID identification code corresponding to the vehicle identification code in the upgrade information database is the current ICCID identification code, the checking process of checking whether the ICCID identification code consists of characters with preset digits is set before the checking process of checking whether the preset ICCID identification code corresponding to the vehicle identification code in the upgrade information database is the current ICCID identification code, therefore, when the ICCID identification code is not composed of characters with preset digits, the parameter information is determined to be wrong, and the process of checking whether the preset ICCID identification code corresponding to the vehicle identification code in the upgrade information database is the current ICCID identification code is not needed, so that the operation load of a remote monitoring platform is reduced.
Further, when the parameter information is verified correctly, feeding back information passing verification; and when the parameter information is checked incorrectly, feeding back information of failed checking.
In an embodiment, when the parameter information is correctly verified, the information that the verification is passed is fed back to the remote upgrading platform, and when the parameter information is incorrectly verified, the information that the verification is failed is fed back to the remote upgrading platform, so that an engineer can judge whether the communication protocol for interaction between the vehicle and the remote monitoring platform is successfully updated or not after the vehicle-mounted terminal software of the vehicle is successfully upgraded according to the information received by the remote upgrading platform. Of course, it can be understood that when the parameter information is verified correctly or the parameter information is verified incorrectly, the information that is verified to pass or the information that is verified to fail can be fed back through the remote monitoring platform itself.
It is understood that the information that the verification fails should further include a location where the parameter information is wrong, for example, the location includes that the current software version number does not exist in the upgrade information database, or a preset ICCID identification code corresponding to the vehicle identification code in the upgrade information database is not wrong location information of the ICCID identification code, so that an engineer can locate the wrong location of the parameter information according to the information that the verification fails and adopt a solution corresponding to the wrong location of the parameter information.
If the parameter information is verified correctly, the step S200 is executed: and determining a communication protocol corresponding to the current software version number in an upgrade information database.
Further, the step S200 is followed by:
and updating the original software version number of the vehicle corresponding to the vehicle identification code in the communication information database to be the current software version number.
The step of updating the original software version number of the vehicle corresponding to the vehicle identification code in the communication information database to the current software version number is used for realizing the real-time updating of the communication information database, so that the current latest software version number bound by the vehicle-mounted terminal of each vehicle can be inquired more intuitively and conveniently.
In this embodiment, the validity and the accuracy of the uploaded parameter information are ensured by checking whether the parameter information is correct, and if the parameter information is correct, determining a communication protocol corresponding to the current software version number in an upgrade information database, so as to further improve the convenience and the accuracy of changing the communication protocol for interacting between the remote monitoring platform and the vehicle.
The invention also proposes a readable storage medium on which the computer program is stored. The readable storage medium may be the Memory 02 in the terminal of fig. 1, or may be at least one of a ROM (Read-Only Memory)/RAM (Random Access Memory), a magnetic disk, and an optical disk, and the computer-readable storage medium includes several pieces of information for enabling the terminal to perform the method according to the embodiments of the present invention.
