[0004] However, existing technologies have low control efficiency for network-connected devices inside vehicles and require high power consumption, which affects the vehicle's driving range and reduces the user's driving experience. Summary of the Invention
[0005] Therefore, the purpose of this invention is to provide a method, system, computer, and readable storage medium for managing vehicle network access devices, in order to solve the problems of low control efficiency and high power consumption of existing technologies for network access devices inside vehicles.
[0006] The first aspect of this invention provides a method for managing vehicle network access devices, the method comprising:
[0007] When a network access application is received from a device, it is determined whether the device meets the network access conditions according to a preset protocol.
[0008] If it is determined that the network access device meets the network access conditions, a virtual register table corresponding to the network access device is established, and the characteristic data of the network access device is obtained. The characteristic data includes the sleep cycle, data upload cycle, and maximum allowed data delay time.
[0009] Based on the sleep cycle, the data upload cycle, and the maximum allowable data delay time, a data routing path corresponding to the network access device is planned so that the network access device uploads the collected data according to the data routing path.
[0010] The beneficial effects of this invention are as follows: When a network access application is received from a network access device, it determines whether the current network access device meets the network access conditions according to a preset protocol. If so, a virtual register table corresponding to the current network access device is established, and the characteristic data of the current network access device is simultaneously acquired.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0043] Existing technologies have low control efficiency for network-connected devices inside vehicles and require high power consumption, which affects the vehicle's driving range and reduces the user's driving experience.
[0044] Please see Figure 1 The image shows a vehicle network access device management method provided in the first embodiment of the present invention. The vehicle network access device management method provided in this embodiment can create the data routing path corresponding to the current network access device in real time during the network access process, thereby enabling targeted reception of data collected by each network access device. It has strong centralized control capabilities and can effectively utilize the data collected by each network access device. At the same time, it has low power consumption and is suitable for widespread promotion and use.
[0045] Specifically, the vehicle network access device management method provided in this embodiment includes the following steps:
[0046] Step S10: When a network access application is received from a network access device, determine whether the network access device meets the network access conditions according to a preset protocol;
[0047] Specifically, in this step, it should first be noted that the vehicle network access device management method provided in this embodiment is implemented based on a central controller and a Wi-Fi-based mesh network framework, wherein the central controller is preferably a PLC. Furthermore, the network access devices provided in this embodiment include in-vehicle wireless network modules, OBD (On-Board Diagnostics) modules, and in-vehicle communication modules, among other network access devices.
[0048] Furthermore, such as Figure 2The diagram shows the network framework of the aforementioned Wi-Fi-based mesh network. The central controller is located at the center of the Wi-Fi-based mesh network and can be connected to the cloud. Accordingly, the user's application can remotely access any device in the Wi-Fi-based mesh network through the cloud, or directly access any device in the Wi-Fi-based mesh network through the central controller.
[0049] Therefore, in this step, it should be noted that when the central controller receives a new network access application from a new network access device, that is, when it receives a new low-power device's network access application, the central controller will immediately determine whether the new network access device meets the network access conditions required in the current network access protocol based on the network access protocol it has pre-stored internally. Preferably, in this embodiment, the network access device sends an application data frame to the central controller in the form of a broadcast.
[0050] Step S20: If it is determined that the network access device meets the network access conditions, a virtual register table corresponding to the network access device is established, and the characteristic data of the network access device is obtained. The characteristic data includes the sleep cycle, data upload cycle, and maximum allowed data delay time.
[0051] Furthermore, in this step, it should be noted that if the central controller determines that the new network access device meets the network access conditions, the central controller will establish a virtual register table corresponding to the current network access device and obtain the characteristic data of the network access device. Specifically, the characteristic data includes the sleep cycle, data upload cycle, and maximum allowed data delay time.
[0052] In this embodiment, it should be noted that the aforementioned network access device is equipped with a register table, and the step of establishing a virtual register table corresponding to the network access device includes:
[0053] When the network access device joins the network, it obtains the device parameters in the register table and maps the device parameters to the virtual register table. The device parameters include the device type and the data acquisition type.
[0054] It should be noted that the aforementioned virtual register table refers to a virtual register table maintained internally by the current central controller. This virtual register table maps the register tables corresponding to all devices in the entire network to the current virtual register table. Specifically, during the network access process of a new device, the current central controller simultaneously obtains the contents of the register table inside the new device, maps the obtained contents to its internally maintained virtual register table, and then distributes the virtual register table mapping relationship to the nodes.
[0055] Additionally, please see Figure 2 It should be noted that the register table stored inside each network access device describes the characteristics of the current network access device itself, including module type, measurement range, accuracy, unit and control parameters, etc., and each parameter has a specific position in the register table.
[0056] In addition, it should be noted in this embodiment that any two low-power devices that have joined the above-mentioned Wi-Fi-based mesh network can communicate via the central controller. That is, any two low-power devices can communicate at the logic layer, and the communication data between them is transmitted through the central controller.
[0057] Step S30: Based on the sleep cycle, the data upload cycle, and the maximum allowable data delay time, a data routing path corresponding to the network access device is planned so that the network access device uploads the collected data according to the data routing path.
[0058] Finally, it should be noted in this step that when the central controller obtains the sleep cycle, data upload cycle, and maximum allowable data delay time of the currently connected device through the above steps, the central controller will plan the data routing path corresponding to the currently connected device based on the sleep cycle, data upload cycle, maximum allowable data delay time, and preset algorithm, so that the currently connected device can upload the collected data in real time according to the planned data routing path.
[0059] In this embodiment, it should be noted that the steps of planning the data routing path corresponding to the network access device based on the sleep cycle, the data upload cycle, and the maximum allowable data delay time include:
[0060] In the current network, identify target devices already connected to the network that have the same sleep cycle as the target devices already connected to the network, including one or more target devices already connected to the network; sequentially establish wireless communication connections between the target devices already connected to the network and the network-connected devices, and set the wireless communication lines between the target devices already connected to the network and the network-connected devices as the optimal data routing path.
[0061] Specifically, in this step, the obtained sleep cycle can be used to accurately classify the currently connected devices, thereby finding the target connected devices with the same sleep cycle in the current network, and establishing wireless communication connections between the target connected devices and the aforementioned connected devices in sequence, so as to set the wireless communication line between the target connected devices and the aforementioned connected devices as the optimal data routing path for the aforementioned connected devices.
[0062] Furthermore, in this step, since the real-time requirements for data acquisition and control logic of agricultural equipment and facilities are relatively low, time comparisons are all performed in units of 10 seconds.
[0063] When the path period of a device adjacent to the currently connected device is inconsistent with the sleep period of the currently connected device, its least common multiple time T≤NodeTd: the least common multiple time is used as the data upload period, and the data is uploaded through the selected path.
[0064] If the least common multiple of the path periods of all adjacent devices and the node's sleep period is T > NodeTd, this usually occurs when the node's NodeTd is close to NodeTs, or TRn ≥ NodeTd.
[0065] Specifically, based on NodeTd, the path with the minimum TR is selected, and the TR time of the path is modified to NodeTd (to speed up the upload cycle of the path).
[0066] Additionally, it should be noted in this step that the routing allocation for new network-joining devices refers to the process after a new network-joining device joins the network and is installed at a location. The new network-joining device can then initiate a route allocation request. This request wakes up all communicable devices near the new network-joining device and selects the device with the shortest path to the central controller as the parent node. The selected parent node reports the path information of the new network-joining device to the central controller, which updates the network routing table and reports the acceptable wake-up period range and register table for the new network-joining device. The central controller then reallocates the path according to the wake-up period range and issues a device wake-up period setting.
[0067] In addition, in this embodiment, the aforementioned feature data also includes a wake-up cycle, and the method further includes:
[0068] When the network access device is in the wake-up period and needs to update data, it updates the acquisition parameters in the register table and uploads the updated incremental data step by step along the data routing path to update the virtual register table.
[0069] It should be noted that every device in the current network has an acceptable wake-up (data reporting and download) cycle range. A standard wake-up cycle is set when the central controller allocates routing paths for devices. If a device is in its standard wake-up cycle and a node on its routing path fails, causing a path interruption, the device will automatically go into sleep mode and wake up in the next cycle. If the next wake-up cycle exceeds the device's acceptable range, the node will wake up surrounding nodes, execute a new node routing allocation process, and update the node routing table.
[0070] In addition, in this embodiment, when the network access device is in a wake-up cycle and needs to update data, it first updates the acquisition parameters in its internal register table, and then uploads the updated incremental data step by step along its set data routing path to update the virtual register table in the central controller.
[0071] This embodiment also provides a virtual register synchronization technology, which includes centralized management and maintenance of the virtual register table and distributed deployment. Centralized management means that the addition, deletion, and modification of the register table of all devices in the virtual table are centrally managed by the central controller; distributed deployment means that after a change operation of the virtual register table, the central controller distributes the virtual table to the deployed devices during the wake-up cycle of each device node, that is, each device retains the latest maintained version of the register area of all devices in the network.
[0072] In addition, in this embodiment, the method further includes:
[0073] If the network-connected device is not woken up within a preset time, it is determined that the device is currently in an offline state, and the device is deleted from the current network, and the virtual register table is updated. Alternatively, in this embodiment, the user can operate a network-connected device to initiate an offline request to the central controller. Upon receiving the offline request, the central controller wakes up all related devices on the data routing path of the currently connected device, reallocates the routing paths of each connected device, and then deletes the requesting device.
[0074] In use, upon receiving a network access application from a device, the system determines whether the device meets the network access requirements according to a preset protocol. If so, a virtual register table corresponding to the device is established, and the device's characteristic data is simultaneously acquired. Furthermore, based on the acquired sleep cycle, data upload cycle, and maximum allowable data latency of the device, a data routing path is planned, enabling the device to upload its collected data according to the created routing path. This method allows for the real-time creation of a data routing path for each device during the network access process, enabling targeted reception of data collected by each device. It provides strong centralized control capabilities, effectively utilizes the data collected by each device, and features low power consumption, making it suitable for widespread adoption and use.
[0075] It should be noted that the above implementation process is only to illustrate the feasibility of this application, but it does not mean that the vehicle network access equipment management method of this application has only the above-mentioned unique implementation process. On the contrary, as long as the vehicle network access equipment management method of this application can be implemented, it can be included in the feasible implementation scheme of this application.
