Figure 2 As shown, the system includes a programming device 21 and a programmable universal transceiver platform 22, and the programming device 21 and the programmable universal transceiver platform 22 are communicatively connected.

[0042] The programming device 21 is used to send the configuration parameters and / or the programming file to the programmable universal transceiver platform 22; The programmable universal transceiver platform 22 is used to configure the communication unit based on the received configuration parameters, and to perform firmware upgrades based on the received programming files.

[0045] The programming method provided by the embodiment of the present invention may include a parameter programming method and a firmware programming upgrade method, and the programming method is executed on the basis of the above-mentioned programmable universal transceiver platform system. Figure 3 One of the flow charts of the parameter programmable method provided by the embodiment of the present invention is as follows: Figure 3 As shown, the parameter programmable methods include: Step 301: the programmable universal transceiver platform receives a first data frame including the configuration parameters sent by the programming device, and after verifying that the first data frame is legal, parses and obtains the configuration parameters; Step 302: The programmable universal transceiver platform executes parameter configuration of the communication unit based on the configuration parameters.

[0046] Optionally, executing parameter configuration of the communication unit includes executing parameter configuration for the first communication unit and / or the second communication unit.

[0047] Optionally, performing the parameter configuration for the first communication unit includes setting parameters for the Sub-1G communication unit; Executing the parameter configuration for the second communication unit includes at least one of the following: Setting of management parameters of the external sensor within the controller unit; Configuration of wired / communication protocols; Configuration of wireless communication protocols.

[0048] Figure 4The second flow chart of the parameter programming method provided by the embodiment of the present invention. The embodiment of the present invention provides multiple interface modes (RS232, RS485, CAN, CANFD, BLE, WIFI) for programming and configuring the programmable universal transceiver platform. The programming and configuration process of each interface mode is similar, such as Figure 4 As shown, the programming and setting methods of the programmable universal transceiver platform are explained by taking the BLE communication method as an example.

[0049] Specifically, it includes: 1. Operate the smart device to configure parameters and send them.

[0050] Initiate connection and connection request: The user initiates the connection by operating the dedicated App installed on the programming device (smartphone / tablet / computer) to send a connection request to the transceiver of the programmable universal transceiver platform to establish a data connection with the receiver.

[0051] Connection response and connection success: The transceiver returns a connection response, and the APP notifies the user that the connection is successful.

[0052] Initiate parameter configuration request: Users configure parameters according to user needs by operating the UI interface provided by the dedicated App.

[0053] When the user clicks the send button, the App will package the set parameters according to the protocol format specified by the communication protocol, and then send the packaged data frame through the BLE communication module.

[0054] 2. The programmable universal transceiver platform receives and processes the data.

[0055] Parameter configuration and storage: When the BLE interface of the programmable universal transceiver platform receives a data frame that complies with the protocol, it will notify the controller to receive the data.

[0056] The controller will parse the received data according to the protocol specifications. First, it will verify whether the checksum of the data frame is legal. If it is legal, it will further process the data content. If it is illegal, it will discard the data frame and respond with an error prompt to the programming device through the BLE interface.

[0057] For legal data frames, the controller will parse the data frame settings according to the protocol, first obtain the type of parameter configuration command, obtain the parameter configuration content according to the parameter configuration type, and refresh the configuration information of the parameter at runtime (that is, refresh the parameter item data stored in RAM), and finally save the configuration content to the memory (that is, refresh the parameter item data stored in ROM / Flash).

[0058] 3. The programmable universal transceiver platform responds to the data processing results.

[0059] Configuration response and configuration result prompt: After the parameter configuration is completed, the programmable universal transceiver platform sends a setting operation result response message to the programming device. Specifically, after the controller unit in the receiver saves the received setting data, it will send a setting operation result response message to the App installed on the programming device. After receiving the response result, the App will display the operation result to the operating user through the UI.

[0060] Figure 5 One of the flowcharts of firmware programming upgrade provided by an embodiment of the present invention is as follows: Figure 5 As shown, the firmware programming upgrade method includes: Step 501: the programmable universal transceiver platform receives a second data frame including the programming file sent by the programming device, and after verifying that the second data frame is legal, parses and obtains the programming file; Specifically, the programmable universal transceiver platform receives an upgrade setting command sent by the programming device, wherein the upgrade setting command includes the file size and version information of the programming file; After the programmable universal transceiver platform parses and obtains the file size and version information of the programming file, it sends a response message to the programming device; The programmable universal transceiver platform receives the upgrade start command sent by the programming device and sets the upgrade state to the upgrade loading state; The programmable universal transceiver platform sequentially receives a plurality of data blocks sent by the programming device, and after receiving a data block sending completion message, verifies the received programming file based on the file size and version information of the programming file included in the upgrade setting command, and sends a success response to the programming device after the verification is passed; The programmable universal transceiver platform receives the firmware verification command sent by the programming device, checks and confirms that the firmware has been received completely, and then returns a response message indicating that the firmware verification is successful.

[0061] Step 502: The programmable universal transceiver platform jumps from the application program to the boot loader to perform a firmware upgrade operation based on the programming file.

[0062] Specifically, the programmable universal transceiver platform sequentially receives the firmware upgrade execution command sent by the programming device, and jumps from the application program to the boot loader; After the firmware upgrade is completed, the device restarts and sends the version information of the programming file to the programming device.

[0063] Optionally, after the firmware upgrade of the programmable universal transceiver platform is completed, the programming file is stored in the memory. Figure 6 The second flowchart of the firmware programming upgrade provided by the embodiment of the present invention is as follows. Figure 6 As shown, similarly, the BLE communication method is taken as an example to explain the programming and setting method of the programmable universal transceiver platform.

[0064] 1. Use your smart device to select the firmware to be upgraded and send it.

[0065] Initiate connection, connection request, connection response and successful connection: The user establishes a data connection with the receiver by operating the dedicated App installed on the programming device (smartphone / tablet / computer).

[0066] The user clicks the firmware selection button on the App UI interface and selects the firmware file to be upgraded.

[0067] The app obtains the file size and version information of the firmware to be upgraded.

[0068] Initiate upgrade and upgrade configuration: When the user clicks the upgrade button, the App starts the upgrade process. First, the upgrade configuration command is sent through the BLE interface of the programming device. The command contains the firmware version information and the firmware length, that is, the file size.

[0069] Parameter configuration and saving and upgrade configuration response: When the BLE interface of the transceiver platform receives the command, it obtains the current firmware version information to be upgraded and returns the response information to the App through the BLE interface.

[0070] Start the upgrade, prepare for the upgrade, and start the upgrade response: When the App receives the response message, it will continue to send the upgrade start command through the BLE interface. After the BLE interface of the transceiver platform receives the upgrade start command, it checks whether the upgrade status of the current internal upgrade management information is idle. If not, the upgrade management information content is cleared and an error response is returned to the App through the BLE interface. If it is, the upgrade status is set to the upgrade loading status, the accepted file data length is set to 0, and the current upgrade management information content is returned to the App through the BLE interface, prompting that the next step can be performed.

[0071] 2. The programmable universal transceiver platform receives and processes the firmware data.

[0072] Firmware transfer and attachment transfer completion request: When the App receives the successful response message of the upgrade start, it starts to start the firmware block file transfer. After the transceiver platform receives the firmware data block, it writes the data block into the storage area designated for the firmware upgrade in the memory and waits for the next data block to be written.

[0073] The App repeatedly sends data blocks until the data block sending is completed. At this time, the App will send a "data block sending completion message" to the transceiver platform through the BLE interface.

[0074] Check whether the upgrade status is correct and the firmware transfer completion request response: After receiving the message, the sending and receiving platform will verify whether the current upgrade status is the upgrade loading status. If not, the upgrade management information content will be cleared, the upgrade process will be exited, and an error response will be returned to the App through the BLE interface. If yes, the firmware length and version information will be verified. If not, the upgrade management information content will be cleared, the upgrade process will be exited, and an error response will be returned to the App through the BLE interface. If yes, a successful response message of "returning the data block sending end message" will be sent to the App through the BLE interface.

[0075] 3. The programmable universal transceiver platform verifies the received firmware file.

[0076] Firmware integrity check request, firmware integrity check and firmware integrity check response: When the App receives a successful response to the "data block sending end command", it sends a "firmware check command" to the transceiver platform through the BLE interface.

[0077] When the transceiver platform receives the "firmware verification command" through the BLE interface, it performs an overall verification of the firmware to check whether the firmware reception is complete (that is, whether the file content is complete). If the check result indicates that the firmware verification is incomplete, the upgrade management information content is cleared, the upgrade process is exited, and an error response is returned to the App through the BLE interface. If the firmware verification is successful, a response message of successful firmware verification is returned to the App through the BLE interface.

[0078] 4. The programmable universal transceiver platform refreshes the new firmware to the application running space.

[0079] Firmware upgrade execution request and firmware upgrade: When the App receives the response message of "firmware verification successful", it sends the "firmware upgrade execution command" to the transceiver platform through the BLE interface.

[0080] When the transceiver platform receives the firmware upgrade execution command, it will jump from the application program to the Bootloader program to execute the firmware update operation. When the firmware upgrade is completed, it will automatically switch to the application program.

[0081] The firmware upgrade is successfully broadcasted with version information and prompts for successful firmware upgrade: The transceiver platform will restart after the firmware upgrade is completed, and send the current version information through BLE broadcast. When the App receives the BLE broadcast message, it verifies whether the current version of the receiver is consistent with the version to be upgraded. If not, the upgrade fails and prompts the user. If yes, the upgrade is successful and prompts the user. (Another way is: after the App establishes a connection with the transceiver platform, it sends a version query command to check whether the transceiver platform firmware has been successfully upgraded. If the queried version is consistent with the version to be upgraded, it means that the upgrade is successful, and the UI interface prompts the user that the current upgrade process has been successfully executed. If the versions are inconsistent, it means that the upgrade failed, and the UI interface prompts the user that the upgrade process failed).

[0082] The following provides specific examples for description.

[0113] The programmable universal transceiver platform, system and programming method provided by each embodiment of the present invention have the following technical effects compared with the prior art: 1. Improved compatibility: Pain points of existing technology: The current transceivers on the market have poor compatibility and can only support one type of sensor. If you need to be compatible with other sensors, you need to update the firmware, so that the originally supported sensors will no longer be able to be used. In addition, constantly updating the firmware for sensor compatibility will make software version management very complicated.

[0114] The programmable universal transceiver platform provided by the embodiment of the present invention supports a multi-channel programmable configuration function. The transceiver platform supports multiple RF channels (including 2.4G, 5G, and Sub-1G). Each RF channel can be individually set as an independent function without the need for firmware upgrades. In addition, it can continue to support newly launched sensors and continue to maintain compatibility with existing sensors.

[0115] 2. Improved convenience: Pain points of existing technology: Currently, the commercial vehicle transceiver systems on the market are all set up in a wired manner, generally connected to the computer through the CAN bus, and then the receiver is programmed and set up by operating the application installed on the computer. This method requires certain professional skills of the operator, and the operation environment is relatively cumbersome to set up, and the whole process is time-consuming and laborious.

[0116] The programmable universal commercial vehicle transceiver platform provided in the embodiment of the present invention is set up by a smart terminal (mobile phone, tablet or computer). The entire process uses a standard BLE or WIFI communication module for communication, eliminating the tedious operation process of wiring. The dedicated App can be installed on the user's mobile phone without the need for professional computer equipment, and the App is simple to operate and does not require high professional skills, so the entire system is simple and easy to use.

[0117] 3. Improved adaptability: Pain points of existing technology: Currently, commercial trailer transceiver systems on the market all use a single interface. Connecting to different platforms often requires redeveloping a set of software and hardware to adapt to the target system. This results in the same series of products not having a unified hardware platform, which is not convenient for manufacturers' production management and project development, and also increases the cost of use for users.

[0118] The programmable universal commercial vehicle transceiver platform provided in the embodiment of the present invention adopts a multi-interface programmable design scheme. The system includes wireless communication modules (BLE and WIFI) and wired communication modules (RS232, RS485 and CAN bus interfaces). The adapted interface type can be selected through programming settings without changing the firmware program. The system has high adaptability, and the software and hardware can be managed in a unified manner, which reduces the cost of use for users.

[0119] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.

[0120] Through the description of the above implementation methods, those skilled in the art can clearly understand that each implementation method can be implemented by means of software plus a necessary general hardware platform, and of course, can also be implemented by hardware. Based on this understanding, the above technical solution is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each embodiment or some parts of the embodiments.
