Description

Background Art

[0002] In the related art, when the in-vehicle positioning terminal upgrades the embedded software version, common methods include importing the new version of the software through serial communication, sending hexadecimal upgrade instructions to the terminal through 8900 transparent transmission of the 808 protocol, and sending a short message upgrade instruction to the SIM card in the terminal device to complete the upgrade of the embedded software version, etc. Among these methods, serial communication requires the computer and the terminal device to be connected by a data cable. The latter two methods require the terminal management platform to support the protocol or the SIM card of the device to support the short message function, and both require the management platform or the mobile phone short message to actively send the upgrade instruction to the device, and also require a server storing the new version of the upgrade program. All three upgrade methods need to meet certain preconditions, and when the number of devices is relatively large, it will cause an increase in workload, possible omissions, and does not meet the requirements of automatic upgrade.

[0003] Therefore, it is necessary to improve one or more problems existing in the above-mentioned related technical solutions.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0020] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0021] In this example embodiment, an automatic remote upgrade method for an in-vehicle positioning terminal based on the http protocol is first provided. This method can be applied to a terminal device, such as a mobile terminal like a mobile phone, personal digital assistant, laptop computer, tablet computer, smart watch, etc.

Flexibly adjust according to specific circumstances, such as if the terminal device is a server, etc.

[0022] Through the above vehicle-mounted positioning terminal automatic remote upgrade method based on the HTTP protocol, on the one hand, the terminal device actively notifies the server of its version number at regular intervals, allowing the server to decide and inform whether it needs to be upgraded. If an upgrade is required, a download request is sent to the server, and the server replies with the software content of the new version to the device. After the device receives it and verifies it without error, it converts the format and replaces the original program. On the other hand, this method realizes automatic device upgrade, reduces the required software and hardware facilities, enables the server to master the access and upgrade situations of numerous devices, and will not cause omissions during the upgrade process.

[0023] Next, reference will be made to Figure 1 to describe each step of the above method in the present exemplary embodiment in more detail.

[0024] In step S101, a new version program file applicable to different device models is selected, and the dedicated upgrade port is listened to.

[0025] Specifically, several new version embedded program files applicable to different device models and their applicable device models are selected as the device models to be upgraded this time and the program versions they need to be upgraded to. The service is started, and the server begins to listen to the port.

[0026] In step S102, a comparison request is received, and the device number, embedded program version number, and device type in the comparison request are extracted.

[0027] Specifically, when the server receives a comparison request (request type POST) sent by a certain device, it obtains its device model, device number, and current version number. It checks whether the device model is included in the selected device models. If not, it means that this device does not need to be upgraded this time, and this comparison request is not replied; if so, it proceeds to step S103.

[0028] In step S103, it is determined whether it belongs to an upgrade model according to the device type; if so, the device number is recorded, it is determined whether the terminal needs to be upgraded, and a corresponding comparison request reply is generated and sent.

[0029] Specifically, the server compares the current version number with the upgrade version number applicable to the current device type. If the versions are the same, this device does not need to be upgraded; if the versions are different, this device needs to be upgraded. The server retrieves and finds that this device is accessing the server for the first time, records the device number of this device and whether it needs to be upgraded. The server returns the device number, upgrade version number, and whether it needs to be upgraded as a reply to the terminal device.

[0030] In step S104, a download request is received and responded to. After verifying the device number, the content of the corresponding new version program file is read, a download request reply is generated and returned.

[0031] Specifically, when the server receives a download request, it first verifies the device number. If the device has been recorded and needs to be upgraded, the server starts to read the new version program file applicable to the device and returns it as a download request reply to the terminal device.

[0032] In step S105, receive the new comparison request sent after the upgrade is completed, and record the upgrade success or failure status according to the version comparison result.

[0033] Specifically, after the server receives the comparison request, it verifies the device model and device number, and finds that it is a second access. It compares the device program versions. If they are the same, the server records that the device upgrade is successful. If they are different, the server records that the device upgrade fails and starts over from step S102.

[0034] It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that these steps must be executed in that specific order, or that all the steps shown must be executed to achieve the desired result. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be decomposed into multiple steps for execution, etc. Also, it is easily understood that these steps may be executed synchronously or asynchronously, for example, in multiple modules / processes / threads.

[0035] Furthermore, in the present exemplary embodiment, an automatic remote upgrade method for an in-vehicle positioning terminal based on the http protocol is also provided. Referring to Figure 2 shown in, this method may include the following steps: Step S201: Send a comparison request at regular intervals; Step S202: Receive the comparison request reply, and determine whether an upgrade is needed according to the comparison request reply; if an upgrade is needed, generate and send a download request including the device number; Step S203: Receive the returned download request reply and verify the download request reply; Step S204: If the verification fails, terminate the upgrade and continue to send the comparison request at regular intervals; Step S205: If the verification is successful, convert the content of the new version program file in the download request reply into the program file format and replace the original program file to complete the upgrade, and immediately send a new comparison request to feedback the upgrade status.

[0036] In step S201, send a comparison request at regular intervals.

[0037] Specifically, the terminal device sends a comparison request to the server at regular intervals. If the device model selected by the server does not include the access device model, the server does not reply. Otherwise, proceed to the next step.

[0038] In step S202, receive the comparison request reply, and determine whether an upgrade is required based on the comparison request reply; if an upgrade is required, generate and send a download request including the device number.

[0039] Specifically, after the terminal device receives the comparison request reply from the server, it first verifies the device number, and then checks whether an upgrade is required. If no upgrade is required, it keeps sending comparison requests to the server at regular intervals; if an upgrade is required, it immediately sends a download request (request type GET) to the server and attaches the device number.

[0040] In steps S203 to S105, receive the returned download request reply, and verify the download request reply; if the verification fails, terminate the upgrade and keep sending comparison requests at regular intervals; if the verification is successful, convert the content of the new version program file in the download request reply into the program file format and replace the original program file to complete the upgrade, and immediately send a new comparison request to feedback the upgrade status.

[0041] Specifically, after the terminal device receives the reply content of the download request, it performs content verification to check its integrity and correctness. If the verification fails, it deletes the content and then keeps sending comparison requests to the server at regular intervals; if the verification is successful, it converts the content into a program file in the correct format, replaces the original program file, the upgrade is successful, and then it immediately sends a new comparison request to the server.

[0042] In a specific embodiment, the comparison request is a POST request sent by the device to the server, and the request parameters are the device number, the embedded program version number, and the device type. After receiving the comparison request, the server will decide whether to record the device number and whether to reply based on the comparison of the device type. If a reply is required, it will decide whether the device needs to be upgraded based on the comparison of the embedded program version number. The fields included in the comparison request reply are the device number, the new version program version number, and whether an upgrade is required. The device sends comparison requests at regular intervals and decides whether to reply and whether to upgrade based on the results, which can ensure reducing the occupancy of the server bandwidth when the device realizes automatic upgrade.

[0043] In a specific embodiment, the download request is a GET request sent by the device to the server, and the attached parameter is the device number. The device will send a download request only when the server notifies the device that an upgrade is required through the comparison request reply. After receiving the download request and verifying the device number, the server reads the content of the new version program and uses it as the download request reply to return to the terminal device.

[0044] In a specific embodiment, content verification is an operation in which a device verifies the verification codes in program files. The program files are all binary files, and a unique verification code is added to the beginning and end of each version of the program file to distinguish it from other versions. When the device receives a download request response, it will verify the verification codes at the beginning and end to check their integrity and correctness. Only when the content verification is passed will the content be converted into the target file format and replace the original program file to complete the upgrade.

[0045] In a specific embodiment, as Figure 3 shown, when the embedded software of a terminal device needs to be remotely and automatically upgraded, the communication process between the terminal and the server in Figure 3 is as follows: "The terminal sends a comparison request" -> "The server replies to the comparison request" -> "The terminal sends a download request" -> "The server replies to the download request". As Figure 4 and Figure 5 shown, in the overall process steps, the main steps include the following: Select several new versions of embedded program files applicable to different device models and their applicable device models as the device models to be upgraded this time and the program versions to which they need to be upgraded, start the service, and the server starts listening on the port.

[0046] The terminal device periodically sends a comparison request to the server. If the device model selected by the server does not include the access device model, the server will not reply, otherwise it will proceed to the next step; When the server receives a comparison request (request type POST) sent by a device, it obtains its device model, device number, and current version number. Checks whether its device model is included in the selected device models. If not, it means that this device does not need to be upgraded this time and does not reply to this comparison request; if so, it proceeds to the next step.

[0047] The server compares the current version number with the upgrade version number applicable to the current device type. If the versions are the same, this device does not need to be upgraded; if the versions are different, this device needs to be upgraded. The server retrieves and finds that this device is accessing the server for the first time, records the device number of this device and whether it needs to be upgraded. The server returns the device number, upgrade version number, and whether it needs to be upgraded as a reply to the terminal device.

[0048] After the terminal device receives the comparison request reply from the server, it first verifies the device number, and then checks whether it needs to be upgraded. If it does not need to be upgraded, it keeps periodically sending comparison requests to the server; if it needs to be upgraded, it immediately sends a download request (request type GET) to the server and attaches the device number, and proceeds to the next step; Upon receiving a download request, the server first verifies the device number. If the device has been recorded and needs to be upgraded, the server starts to read the new version program file applicable to the device and returns it as a reply to the download request to the terminal device. After receiving the reply content of the download request, the terminal device performs content verification to check its integrity and correctness. If the verification fails, the content is deleted, and then the terminal device keeps sending comparison requests to the server at regular intervals. If the verification is successful, the content is converted into a program file in the correct format to replace the original program file, and the upgrade is successful. Then, the terminal device immediately sends a comparison request to the server again.

[0049] After receiving the comparison request, the server verifies the device model and device number, and finds that it is a secondary access. It compares the device program versions. If they are the same, the server records that the device upgrade is successful. If they are different, the server records that the device upgrade fails and sends a comparison request to the server again.

[0050] Through the above-mentioned method for automatic remote upgrade of in-vehicle positioning terminals based on the http protocol, on the one hand, the terminal device actively and regularly informs the server of its version number, enabling the server to decide and inform whether it needs to be upgraded. If an upgrade is required, the terminal device sends a download request to the server, and the server replies with the software content of the new version to the device. After receiving it and verifying it without errors, the device converts the format and replaces the original program. On the other hand, this method realizes automatic device upgrade, reduces the required software and hardware facilities, enables the server to master the access and upgrade situations of numerous devices, and there will be no omissions during the upgrade process.
