[0001] The present invention relates to the technical field of aerial work platforms, and in particular to a remote upgrading method, system and readable storage medium. Background Art

[0002] The electronic control system of the self-propelled scissor lift (hereinafter referred to as the lift) on the market currently contains sub-devices such as the platform controller (PCU), chassis controller (ECU), motor driver, and voice alarm. Among them, the platform controller and the chassis controller communicate with one CAN bus, and the other devices communicate with the chassis controller with another CAN bus.

[0003] With the intelligentization and networking of automobiles, Over-the-Air Technology (OTA) technology is becoming more and more mature, and vehicles equipped with OTA functions have gradually become a trend. This function can push new functions to users in a timely and efficient manner to improve user experience. The promotion of OTA technology and the use of TBOX that supports communication networks to upgrade electronic equipment on aerial work vehicles have become a major trend. Since the chassis controller and motor driver on the aerial work vehicle can be directly connected to TBOX, they can be directly upgraded remotely, but the platform controller cannot be directly connected to TBOX. Therefore, how to achieve remote upgrades of the platform controller is a problem that aerial work vehicles currently need to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a remote upgrade method, system and readable storage medium to solve the problem of remote upgrade of the aerial work vehicle platform controller.

[0006] receiving the software version of the platform controller through the chassis controller, and forwarding the software version information to the platform server through the TBOX;

[0007] Detecting whether the software version is the latest version by the platform server;

[0008] If not, the platform server forwards the upgrade data to the chassis controller via the TBOX, and then forwards it to the platform controller via the chassis controller. The platform controller automatically upgrades after receiving the upgrade data.

[0009] Optionally, when the platform server detects that the software version is not the latest version, the remote upgrade method further includes:

[0010] The platform server sends an upgrade instruction to the chassis controller through the TBOX;

[0012] After receiving the upgrade permission instruction, the platform server forwards the upgrade data to the chassis controller through the TBOX.

[0013] Optionally, if the user does not confirm whether to upgrade within a preset time, the chassis controller sends a cancel upgrade instruction to the platform server through the TBOX, and the platform server no longer prompts for the current version upgrade.

[0014] Optionally, if the chassis controller confirms not to upgrade, the chassis controller sends a cancel upgrade instruction to the platform server through the TBOX, and the platform server no longer prompts for upgrading the current version.

[0015] Optionally, the platform controller is communicatively connected to the chassis controller via a first CAN bus, the chassis controller is communicatively connected to the TBOX via a second CAN bus, and the TBOX is communicatively connected to the platform server via a communication network.

[0020] The platform controller is used for automatically upgrading after receiving the upgrading data.

[0021] Optionally, when the platform server detects that the software version is not the latest version, the platform server is further used to send an upgrade instruction to the chassis controller through the TBOX, and to forward the upgrade data to the chassis controller through the TBOX after receiving an upgrade permission instruction fed back from the chassis controller.

[0022] Optionally, the platform controller is communicatively connected to the chassis controller via a first CAN bus, the chassis controller is communicatively connected to the TBOX via a second CAN bus, and the TBOX is communicatively connected to the platform server via a communication network.

[0033] Please refer to Figure 1-Figure 2 This embodiment provides a remote upgrade method for remotely upgrading a platform controller 101 of an aerial work vehicle 100. The aerial work vehicle 100 further includes a chassis controller 102 and a TBOX 103. The platform controller 101 is connected in communication with the chassis controller 102. The chassis controller 102 is connected in communication with the platform server 200 through the TBOX 103. The remote upgrade method includes the following steps:

[0034] S1, receiving the software version of the platform controller 101 through the chassis controller 102, and forwarding the software version information to the platform server 200 through the TBOX103;

[0035] S2, detecting whether the software version is the latest version through the platform server 200;

[0036] S3. If not, the platform server 200 forwards the upgrade data to the chassis controller 102 via the TBOX 103, and then forwards it to the platform controller 101 via the chassis controller 102. The platform controller 101 automatically upgrades after receiving the upgrade data.

[0037] The present invention forwards the upgrade data to the platform controller 101 which cannot directly perform OTA through the chassis controller 102, thereby realizing the remote upgrade of the platform controller 101, breaking the current situation that the platform controller 101 of the aerial work vehicle 100 cannot support OTA, and expanding the application scope of the OTA function of the aerial work vehicle 100.

[0038] In this embodiment, the platform controller 101 is fixed on the operating platform of the aerial work vehicle 100, and is connected to the chassis controller 102 via a first CAN bus. The platform controller 101 can be operated by the user, and the user's control information is sent to the chassis controller 102 via the first CAN bus. The chassis controller 102 is located on the chassis and is connected to the TBOX103 via a second CAN bus. The chassis controller 102 receives data transmitted by the platform controller 101 via the first CAN bus to determine whether the user's control information meets the execution conditions, and sends the relevant execution information to the motor driver. At the same time, the current vehicle working status is sent to TBOX103 via the second CAN bus. TBOX103 is connected to the platform server 200 via a communication network for transmitting the vehicle working status information to the platform server 200.

[0039] Preferably, the communication network includes but is not limited to a 4G communication network or a 5G communication network.

[0040] First, step S1 is executed to receive the software version of the platform controller 101 through the chassis controller 102, and forward the software version information to the platform server 200 through the TBOX103. Every time the vehicle is started, the chassis controller 102 automatically receives the software version of the platform controller 101, and sends the software version information to the TBOX103, which then forwards it to the platform server 200.

[0041] Then, S2 is executed to detect whether the software version is the latest version through the platform server 200, and the platform server 200 compares the software version to determine whether it is the latest program version.

[0042] Finally, S3 is executed. If not, the platform server 200 forwards the upgrade data to the chassis controller 102 via TBOX103, and then forwards it to the platform controller 101 via the chassis controller 102. The platform controller 101 automatically upgrades after receiving the upgrade data.

[0043] Preferably, when the platform server 200 detects that the software version is not the latest version, the remote upgrade method further includes:

[0044] The platform server 200 sends an upgrade instruction to the chassis controller 102 via TBOX103;

[0045] The user confirms whether to upgrade through the chassis controller 102. If the upgrade is confirmed, the user sends an upgrade permission instruction to the platform server 200 through the TBOX 103;

[0046] After receiving the upgrade permission instruction, the platform server 200 forwards the upgrade data to the chassis controller 102 through the TBOX 103 .

[0047] For example, when the platform server 200 detects that the software version is not the latest version, it sends the "PCU upgrade request" instruction to TBOX103. After receiving the "PCU upgrade request" instruction, TBOX103 forwards it to the chassis controller 102. After receiving the "PCU upgrade request" instruction, the chassis controller 102 displays "PCU program has been updated, do you want to upgrade?" and other similar words on the screen. After the user sees the words, press the "Confirm" or "Return" button to inform the ECU whether it agrees to upgrade. If the upgrade is confirmed, the platform server 200 is sent an upgrade permission instruction through TBOX103. After receiving the upgrade permission instruction, the platform server 200 sends the upgrade data to TBOX103 through the communication network. TBOX103 then forwards the upgrade data to the chassis controller 102 through the second CAN bus. Finally, the chassis controller 102 forwards the upgrade data to the platform controller 101 through the first CAN bus. The platform controller 101 automatically upgrades after receiving the upgrade data.

[0048] Preferably, if the user does not confirm whether to upgrade within the preset time, the chassis controller 102 sends a cancel upgrade instruction to the platform server 200 through TBOX103, and the platform server 200 no longer prompts the current version to upgrade. The preset time can be set by yourself, and the present invention is not limited to this. Of course, in addition to no longer prompting the current version to upgrade, the platform server 200 can also send an upgrade instruction to the chassis controller 102 through TBOX103 again after a period of time to remind the user to upgrade.

[0049] In this embodiment, if the chassis controller 102 confirms that no upgrade is required, the chassis controller 102 sends a cancel upgrade instruction to the platform server 200 through the TBOX 103, and the platform server 200 no longer prompts for the current version upgrade.

[0050] Based on the same invention concept, please refer to Figure 2 The embodiment of the present invention further provides a remote upgrade system, including a platform controller 101, a chassis controller 102, a TBOX 103 and a platform server 200, wherein the platform controller 101 is connected to the chassis controller 102 in communication, and the chassis controller 102 is connected to the platform server 200 in communication via the TBOX 103; wherein,

[0051] The chassis controller 102 is used to receive the software version of the platform controller 101 and forward the software version information to the platform server 200 via the TBOX 103;

[0052] The platform server 200 is used to detect whether the software version is the latest version. If not, the platform server 200 is also used to forward the upgrade data to the chassis controller 102 through the TBOX 103, and the chassis controller 102 is also used to forward the upgrade data to the platform controller 101;

[0053] The platform controller 101 is used for automatically upgrading after receiving the upgrading data.

[0054] Preferably, when the platform server 200 detects that the software version is not the latest version, the platform server 200 is also used to send an upgrade instruction to the chassis controller 102 through TBOX103, and to forward the upgrade data to the chassis controller 102 through TBOX103 after receiving the upgrade permission instruction fed back by the chassis controller 102.

[0055] Preferably, the platform controller 101 is communicatively connected to the chassis controller 102 via a first CAN bus, the chassis controller 102 is communicatively connected to the TBOX 103 via a second CAN bus, and the TBOX 103 is communicatively connected to the platform server 200 via a communication network.

[0056] Based on the same inventive concept, an embodiment of the present invention further provides a readable storage medium on which a computer program is stored. When the computer program is executed, the above remote upgrade method can be implemented.

[0057] The readable storage medium can be a tangible device that can keep and store the instructions used by the instruction execution device, such as but not limited to an electrical storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device or any suitable combination thereof.

The computer program can be executed completely on the user's computer, partially on the user's computer, as an independent software package, partially on the user's computer and partially on the remote computer, or completely on the remote computer or server. In the case of a remote computer, the remote computer can be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or can be connected to an external computer (for example, using an Internet service provider to connect through the Internet).
