After the lawn mower robot enters the lawn in the working area, the user uses the control terminal to transmit remote control instructions to the automatic lawn mower; at the same time, the lawn mower robot needs to reply to the control terminal, including replying to the command, uploading the machine status or information.

[0025] In order to achieve remote control, the terminal device can establish a data transmission link with the lawn mower through the communication module. The lawn mower supports multiple types of communication modules, and when the terminal device establishes a connection with it, it usually gives priority to completing the initial link establishment through the default transmission interface.

This method effectively improves task execution efficiency, optimizes resource utilization, adapts to multi-task requirements, and simplifies user operations through distributed gateway deployment, which is suitable for multi-task, multi-scenario device communication requirements. That is, different data channels can be used to transmit data through a set of equipment, and the overall IOT (Internet of Things) data transmission and reception work can be completed through one interface. To facilitate understanding of the data transmission method provided in the embodiment of the present application, the following will be explained in conjunction with its different implementation processes.

[0027] In some embodiments, a flowchart of a data transmission method is as follows: Figure 1 As shown, the following steps are included:

[0028] Step 101: Receive a first data packet sent by a control terminal based on a data interface of a data gateway.

[0029] Step 102: According to the first data packet and a preset rule, a target communication module matching the first data packet is searched among a plurality of communication modules.

[0030] Step 103: Send the first data packet to the device end through the target communication module.

[0031] In this way, by adding a data gateway to the remote device or device end, the data packets sent by each terminal are sent and received through the data gateway; wherein, the identification information in the data packet indicates the task type, and the communication module is dynamically matched in combination with the preset rules, and the design of a multi-module shared data interface is used to realize the intelligent selection of the data transmission path. This method effectively improves the efficiency of task execution, optimizes resource utilization, adapts to multi-task requirements, and simplifies user operations through distributed gateway deployment, which is suitable for multi-task and multi-scenario device communication requirements. Through a set of equipment, different data channels can be used to transmit data, and the overall IOT (Internet of Things) data transmission and reception work can be completed through one interface.

[0032] To facilitate better understanding of those skilled in the art Figure 1 The method shown in the figure will be further described below.

[0033] In step 101, the data gateway receives a first data packet sent by the control end based on the data interface; wherein the first data packet includes at least target data and identification information of the target data, and the identification information is at least used to indicate the task to be performed by the device end, and the tasks include at least: mapping tasks, mowing tasks, driving tasks, charging tasks, equipment maintenance tasks and / or equipment configuration tasks.

[0034] Further, in step 101, the target data may include map data, log data, device status data, device sensor data, device task data, device historical work data, and device firmware or new upgrade firmware. The identification information may include information for identifying the target data, such as: data volume identification (such as data link, number of data records, and data sampling rate, etc.), data type identification (such as data format, data type, and data dimension, etc.), and data source identification (such as device ID, data collection time, etc.), data reliability identification (such as data integrity, data validity, and data trustworthiness, etc.), and related security identification (such as encryption status and permission identification, etc.). The identification information may also include information used to prompt or specify the transmission method of the target data, such as: communication channel identification (such as channel type, channel number, channel bandwidth, etc.), port identification (such as TCP / UDP port number, port range, port protocol, etc.), communication protocol identification (such as transmission protocol and encryption protocol, etc.), etc.; the identification information may also include information used to indicate the data receiving device, such as: device identification (such as device ID, device name), device type identification (such as device category, device model and device function identification, etc.), device address identification (such as network address, geographic location and area number), communication target identification (such as communication channel, port, gateway or path information, etc.); the identification information may also include information used to indicate data broadcast or multicast, such as device group identification (such as device group ID, scene group and area group, etc.), collaboration identification (such as master-slave device and queue number, etc.); the identification information may also include information indicating network performance status, such as: data transmission method (such as traffic priority and data rate, etc.), network optimization (such as device load status and diversion strategy), etc.

[0035] In step 102, the data gateway obtains the data packet from the control end, and searches for a target communication module matching the first data packet in a plurality of communication modules according to the data packet and a preset rule, wherein the preset rule is used to indicate the mapping relationship between the identification information of the data and the communication module, and the plurality of communication modules share the same data interface.

[0036] In this way, by combining target data analysis and dynamic matching of identification information, we can achieve the high efficiency of designated priority while taking into account the flexibility in unspecified scenarios, making the communication module selection more intelligent and accurate.

[0037] Further, in some embodiments, the communication module in step 102 may include: a first communication module and a second communication module, and the transmission efficiency of the second communication module is lower than that of the first communication module. Specifically, the first communication module should be an efficient transmission module for high-bandwidth, low-latency data transmission, wherein the first communication module applied to long-distance wireless communication may be a communication module of Wi-Fi (wireless local area network), 5G network or millimeter wave, etc., and the first communication module applied to short-distance wireless communication may be a communication module of UWB (Ultra-Wide Band) or WiGig (Wireless Gigabit), etc.; the second communication module has low transmission efficiency and has the characteristics of lower power consumption, wherein the second communication module applied to short-distance wireless communication may be a communication module of LoRa (Long Range Radio, long-distance low-power network), NB-IoT (Narrow Band Internet of Things), 2G / 3G network, Sigfox (Low Power Wide Area Network), Classic Bluetooth (Bluetooth Classic), RFID (Radio Frequency Identification), ZigBee or infrared communication, etc.

[0038] This application provides a feasible embodiment, taking the first communication module as a Wi-Fi module and the second communication module as a Bluetooth module as an example. Of course, the above is only an example, and the relevant settings may be different according to different application scenarios, different requirements, different hardware capabilities, etc., and will not be repeated here.

[0039] In some embodiments, for step 102, the preset rule may be a business dictionary. Some examples of business dictionaries are given here, as shown in Table 1.

[0040] Table 1 Business dictionary (part)

[0041]

[0042] In some embodiments, for step 102, finding a target communication module that matches the first data packet among several communication modules can be achieved in the following manner: parsing the first data packet to obtain identification information; if the target communication module has been specified in the identification information, the specified communication module is used as the determined target communication module; if the target communication module is not specified in the identification information, the corresponding target communication module is determined based on the identification information and preset rules.

[0043] The identification information may include information for prompting or specifying the transmission mode of the target data, such as: communication channel identification (such as channel type, channel number, channel bandwidth, etc.), port identification (such as TCP / UDP port number, port range, port protocol, etc.), communication protocol identification (such as transmission protocol and encryption protocol, etc.), etc. The data gateway may determine the communication module according to the identification information, and further search for the target communication module from several communication modules.

[0044] Furthermore, in step 102, finding the target communication module that matches the first data packet among several communication modules can also be achieved in the following manner: identifying the task type indicated by the identification information of the first data packet, and determining the corresponding target communication module from several communication modules according to the task type: wherein, if the task type belongs to the first task, the communication module is determined to be the second communication module; if the task type belongs to the second task, the communication module is determined to be the first communication module; the data volume of the first task is smaller than that of the second task, or / and the number of interactive end devices of the first task is smaller than that of the second task.

[0045] Further, in some embodiments, the first task includes at least: an equipment configuration task; the second task includes at least: a mapping task, a mowing task, an equipment maintenance task, or a driving task;

[0046] Among them, the mapping task at least includes configuring the map; the equipment maintenance task at least includes obtaining equipment logs, historical records and firmware updates; the equipment configuration task at least includes configuring equipment working parameters and task plans; the mowing task at least includes configuring the equipment mowing action, area and path; the driving task at least includes configuring the equipment form path and area.

[0047] Furthermore, in some embodiments, the process of the data transmission method can also be as follows: Figure 2 As shown, after step 102, in some embodiments, the following steps may also be included:

[0048] Step 104: Acquire the networking status of the control terminal and the device terminal.

[0049] In step 104, when the data gateway is deployed on a remote device, the network status of the control end and the device end is obtained; if either the control end or the device end is disconnected from the network, the first data packet and / or the second data packet is uploaded to the cloud server and a prompt is given. The remote device may be a cloud device (such as a cloud server or an edge computing node), a network relay device (such as a router, an access point, or a charging station for a device), or other device ends that constitute a device group.

[0050] In this way, through network status detection and cloud transit technology, the reliability and flexibility of the system are significantly enhanced, solving the problems of data loss and task interruption caused by network disconnection, and optimizing the user experience. It is suitable for application scenarios with complex or unstable network environment.

[0051] Another embodiment of the present invention provides a data transmission method, which is applied to a control terminal. Figure 3 shown.

[0052] Step 201: Generate a first data packet, and send the first data packet to a data gateway.

[0053] Step 202: Receive a second data packet sent by the data gateway.

[0054] To facilitate better understanding of those skilled in the art Figure 3 The method shown in the figure will be explained in the following steps.

[0055] In step 201, the control end generates a first data packet, which is used to instruct the device end to perform a map modeling task, a device maintenance task and / or a device configuration task; the first data packet is sent to the data gateway, so that the data gateway parses the first data packet to obtain parsed data, and sends the parsed data to the device end based on the target communication module.

[0056] In this way, the task instruction (first data packet) is generated by the control end, parsed by the data gateway, and forwarded to the device end using the target communication module to ensure efficient transmission and accurate execution of the instruction. This design realizes the hierarchical management of tasks and the decoupling of data processing, improves the flexibility of data transmission and the accuracy of task execution, and is suitable for remote control of various task types (such as map modeling, equipment maintenance, etc.) in complex systems. At the same time, the control end is only responsible for receiving and sending data, and simplifies user operations through distributed gateway deployment, which is suitable for multi-task and multi-scenario device communication needs.

[0057] Another embodiment of the present invention provides a data transmission method, which is applied to a device. The specific process is as follows: Figure 4 shown.

[0058] Step 301: Receive a parsed first data packet sent by a data gateway.

[0059] Step 302: Execute corresponding tasks according to the identification information to generate data to be uploaded.

[0060] Step 303: Send the data to be uploaded to the data gateway.

[0061] To facilitate better understanding of those skilled in the art Figure 4 The method shown in the figure will be explained in the following steps.

[0062] In step 301, the first data packet includes at least target data and identification information of the target data, and the identification information is at least used to indicate the task to be performed on the device side, and the task includes at least: map modeling task, mowing task, driving task, charging task, equipment maintenance task and / or equipment configuration task.

[0063] In step 302, the device executes the corresponding task and generates data according to the executed task, wherein the data may be a map, a log, a device status, a historical work record of the device, etc.

[0064] In step 303, the device sends the data to be uploaded to the data gateway, so that the data gateway packages the uploaded data to obtain a second data packet, and sends the second data packet to the control end based on the target communication module.

[0065] In this way, through the above method, the device side does not need to worry about the packaging and unpacking of data, nor does it need to worry about the selection of data channels. Any data channel shares a set of structured data, and the overall IOT data transmission and reception work can be completed through the interface.

[0066] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.
