[0003] As a low-cost and low-power solution for 4G LTE communication technology, the CAT.1 module provides stable and efficient data transmission capabilities for embedded devices. Through the CAT.1 module, it can help achieve remote monitoring, real-time data sharing, and rapid response between embedded devices, greatly improving flexibility and efficiency.

[0068] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0069] The embodiments of the present application provide a data interaction method for multiple embedded devices based on a CAT.1 module. The execution subject of the data interaction method for multiple embedded devices based on the CAT.1 module includes, but is not limited to, at least one of electronic devices such as a server, a terminal, etc. that can be configured to execute the method provided by the embodiments of the present application. In other words, the data interaction method for multiple embedded devices based on the CAT.1 module can be executed by software or hardware installed on a terminal device or a server device. The server includes, but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc.

[0070] Embodiment 1:

[0071] Refer to Figure 1 As shown, it is a schematic flowchart of a data interaction method for multiple embedded devices based on a CAT.1 module provided by an embodiment of the present invention. In this embodiment, the data interaction method for multiple embedded devices based on the CAT.1 module includes:

[0072] S1. Receive a data interaction instruction initiated by an instruction initiating device, and send the data exchange instruction to the CAT.1 module, where the device type of the instruction initiating device is embedded.

[0073] It should be noted that the device type of the instruction initiating device in the embodiments of the present invention is embedded. Exemplarily, Xiao Zhang is an engineer in an automotive parts manufacturing enterprise. There are multiple production lines in this automotive parts manufacturing enterprise. Each production line can independently produce automotive parts, and each production line includes a programmable logic controller (PLC) and a microcontroller (MCU) for controlling the production links of the production line. The network environment where the production line is located includes routers, switches, monitoring devices, etc. Then, the programmable logic controller (PLC), the microcontroller (MCU), routers, switches, monitoring devices, etc. can all be referred to as embedded devices.

[0074] Exemplarily, if Xiao Zhang wants to adjust the device parameters of a certain production link in the production line, he plans to rewrite the logic code through the PLC. Therefore, he first uses the PLC to initiate a data interaction instruction to notify all other embedded devices that have a relevant relationship with the purpose of rewriting the logic code.

[0075] In addition, the CAT.1 module (Category 1 module) is a communication module implemented based on LTE (Long-Term Evolution) technology. The CAT.1 module supports some basic functions in the LTE network, and has a low data transmission rate and low cost. It is generally applied in less complex data interaction environments, especially in the data interaction between the embedded devices described in the embodiments of the present invention. Further, sending the data exchange instruction to the CAT.1 module includes:

[0076] Starting the CAT.1 module, where the CAT.1 module includes a wireless transmission unit, a modem, a radio frequency front end, and a controller;

[0077] Identifying the wireless network where the instruction initiating device is located to obtain the available wireless network and the IP address of the instruction initiating device;

[0078] Sending the data exchange instruction to the CAT.1 module using the available wireless network. At the same time, when the CAT.1 module receives the data exchange instruction, generating a data test instruction using the wireless transmission unit;

[0079] Sending the data test instruction to the IP address of the instruction initiating device using the available wireless network and waiting for the test response instruction returned by the instruction initiating device;

[0080] If the CAT.1 module successfully receives the test response instruction, receiving the data exchange instruction using the wireless transmission unit.

[0081] Exemplarily, Xiao Zhang plans to modify the logic code through the PLC. Therefore, the PLC is used to initiate a data interaction instruction first. In this case, the PLC is the instruction-initiating device. Therefore, before executing the PLC to modify the logic code, the CAT.1 module needs to be started. The role of the CAT.1 module is to assist the PLC in distributing the task of modifying the logic code to other embedded devices that have a relevant relationship with the modified logic code. To ensure the security of the entire process, in the embodiment of the present invention, it is necessary to first confirm the feasibility of the data interaction between the CAT.1 module and the PLC. Therefore, the wireless transmission unit of the CAT.1 module is used to generate a data test instruction, and the data test instruction is used to test whether the PLC can return a test response instruction.

[0082] S2. Determine the type of the data exchange instruction in the CAT.1 module to obtain the instruction type, and determine one or more instruction-receiving devices that have the possibility of data interaction with the instruction-initiating device according to the instruction type.

[0083] It should be explained that different types of data interaction instructions may involve different embedded devices. Therefore, determining the type of the data interaction instruction can achieve a more refined screening of the instruction-receiving devices.

[0084] Specifically, determining the type of the data exchange instruction in the CAT.1 module to obtain the instruction type includes:

[0085] Analyze the data exchange instruction in the wireless transmission unit to obtain the data interaction purpose;

[0086] Based on the data interaction purpose, confirm the instruction type. Among them, the instruction type includes arithmetic calculation instructions, data transmission instructions, logical calculation instructions, data encryption instructions, and code modification instructions.

[0087] Exemplarily, if Xiao Zhang plans to modify the logic code through the PLC, the corresponding data interaction instruction belongs to the code modification type. Arithmetic calculation instructions include addition (ADD), subtraction (SUB), multiplication (MUL), division (DIV), etc. Logical calculation instructions include performing operations such as AND, OR, NOT, XOR, etc., or performing unconditional jumps (JUMP), conditional jumps, and loop controls.

[0088] It should be noted that different embedded devices correspond to different instruction types. For example, if a PLC is used as an instruction-initiating device to plan to modify logic code, then the embedded device that needs to execute the code must be related to the code modification instruction type, such as the PLCs on other production lines. Through the instruction type, the instruction-receiving devices that may have data interaction with the instruction-initiating device can be initially identified. For example, if Xiao Zhang wants to obtain the production status of automotive parts on the production line through a microcontroller (MCU), then a data transmission instruction needs to be executed to obtain the production monitoring diagram of the production line, and the devices related to the data transmission instruction type may include monitoring devices, etc.

[0089] S3. Obtain the data interaction records between the instruction-initiating device and each instruction-receiving device in the historical time period, and construct a data interaction network centered on the instruction-initiating device based on the data interaction records in the historical time period.

[0090] Specifically, the obtaining of the data interaction records between the instruction-initiating device and each instruction-receiving device in the historical time period includes:

[0091] Receive the historical time period set by the operator of the instruction-initiating device, where the historical time period consists of a start time point and an end time point;

[0092] Directly send the test response instruction returned by the instruction-initiating device to the database that supports the operation of the CAT.1 module;

[0093] Directly forward the test response instruction in the database to the wireless transmission unit in the CAT.1 module for verification. If the verification is passed, when the database responds to the test response instruction, establish a connection channel between the instruction-initiating device and the database, and use the connection channel to send the historical time period composed of the start time point and the end time point to the database;

[0094] Search for the data interaction records between the instruction-initiating device and other instruction-receiving devices in the database with the start time point and the end time point as search conditions.

[0095] It should be noted that when the CAT.1 module runs, a large amount of module operation data, network traffic data, device interaction data, etc. will be generated. The database that supports the operation of the CAT.1 module is used to store such data. Since there is a direct correlation between data interaction between the database and the CAT.1 module, in order to maximize the simplification of the process, in the embodiment of the present invention, the test response instruction returned by the instruction initiating device is directly sent to the database. If the database receives the test response instruction, it will forward the test response instruction to the CAT.1 module for execution and confirmation. If the CAT.1 module confirms that the test response instruction has been received by the infinite transmission unit before (i.e., the above verification process), the database will respond to the test response instruction.

[0096] Further, the structure of the data interaction record is:

[0097] ;

[0098] Among them, represents the data interaction record between the j-th instruction initiating device and other instruction receiving devices, represents the number of data interactions between the j-th instruction initiating device and the i-th instruction receiving device, and m represents the number of instruction receiving devices.

[0099] Exemplarily, if Xiao Zhang plans to modify the logic code through the PLC, and there are 5 production lines where Xiao Zhang is located, and there are 3 PLCs on each production line, then in the embodiment of the present invention, it is necessary to obtain the data interaction records between the PLC and the other 14 PLCs, that is, The value of is 14.

[0100] Specifically, constructing a data interaction network centered on the instruction initiating device according to the data interaction records in the historical time period includes:

[0101] Determine the data flow directionality of the instruction initiating device when performing data interaction with other instruction receiving devices according to the data interaction instructions initiated by the instruction initiating device, where the data flow directionality is divided into unidirectionality and bidirectionality;

[0102] Optimize the data interaction record according to the data flow directionality to obtain a flow interaction record, where the structure of the flow interaction record is:

[0103] ;

[0104] Among them, represents the flow interaction record between the j-th instruction initiating device and other instruction receiving devices, represents the number of data interactions between the j-th instruction initiating device and the 1st instruction receiving device, and the data flow directionality of the data interaction is bidirectional, represents the number of data interactions between the j-th instruction initiating device and the second instruction receiving device, and the data flow direction of the data interaction is unidirectional, that is, the j-th instruction initiating device flows data to the second instruction receiving device. represents the number of data interactions between the j-th instruction initiating device and the m-th instruction receiving device, and the data flow direction of the data interaction is unidirectional, that is, the m-th instruction receiving device flows data to the j-th instruction initiating device;

[0105] According to the flow interaction record, a data interaction network centered on the instruction initiating device is constructed.

[0106] Exemplarily, there are 5 production lines in total, and each production line has 3 PLCs. Then, in the embodiment of the present invention, it is necessary to obtain the data interaction records of the PLC with the other 14 PLCs, that is, the value of m is 14. If it is found through the data interaction records in the historical time period that the data interaction between the PLC used by Xiao Zhang and the other 14 PLCs is unidirectional and bidirectional, then it is necessary to sort out the specific data flow directions from the PLC used by Xiao Zhang to the other 14 PLCs, so as to construct the above-mentioned flow interaction record.

[0107] Further, the constructing a data interaction network centered on the instruction initiating device according to the flow interaction record includes:

[0108] Taking the instruction initiating device as the center point, and calculating the radius value according to the number of instruction receiving devices in the flow interaction record;

[0109] Distributing the instruction receiving devices evenly around the instruction initiating device, and the distance between each instruction receiving device and the instruction initiating device is the radius value;

[0110] Constructing a weighted connection line including direction according to the flow interaction record;

[0111] Connecting the instruction initiating device and each instruction receiving device with the weighted connection line to obtain the data interaction network, wherein the connection direction of the weighted connection line is the same as the data flow direction recorded in the flow interaction record.

[0112] Specifically, the calculating the radius value according to the number of instruction receiving devices in the flow interaction record includes:

[0113] Calculating the radius value according to the following formula:

[0114] ;

[0115] wherein, represents the radius value with the j-th instruction initiating device as the center point, and m represents the number of instruction receiving devices. It represents a pre-set maximum radius value, and the maximum radius value needs to be less than or equal to the number of instruction receiving devices.

[0116] Exemplarily, after taking the PLC used by the above-mentioned Xiaozhang as the origin point, the PLC used by Xiaozhang is the instruction initiating device. Assuming that there are 30 instruction receiving devices for the PLC used by Xiaozhang, then according to the above formula, the radius value of the PLC used by Xiaozhang can be calculated. It can be understood that the larger the number of instruction receiving devices, the larger the corresponding radius value.

[0117] Furthermore, the weighted connection line described in the embodiment of the present invention includes two important parameters. The first is the direction, and the second is the weight. The direction mainly depends on the upward arrow symbol in the above-mentioned flow interaction record. For example, If it represents that the data flow direction of data interaction is bidirectional, then both ends of the weighted connection line between the j-th instruction initiating device and the first instruction receiving device have arrows, indicating bidirectionality. For example, If it represents that the j-th instruction initiating device flows data to the second instruction receiving device, then for the weighted connection line between the j-th instruction initiating device and the second instruction receiving device, only the port of the second instruction receiving device has an arrow, which means that the j-th instruction initiating device flows data to the second instruction receiving device.

[0118] In addition, the second important parameter of the weighted connection line is the weight, and the size of the weight is positively correlated with the number of data interactions. That is, the larger the number of data interactions, the larger the weight of the weighted connection line. Then, in the performance of the data interaction network, the weighted connection line is thicker. On the contrary, the smaller the number of data interactions, the thinner the weighted connection line. Specifically, the calculation formula for the weight of the weighted connection line is:

[0119] ;

[0120] Wherein, represents the weight of the weighted connection line between the j-th instruction initiating device and the i-th instruction receiving device. represents the number of data interactions between the j-th instruction initiating device and the i-th instruction receiving device, k represents a pre-set slope value, and b represents a pre-set offset value.

[0121] According to the above description, each instruction receiving device and the instruction initiating device have a corresponding weighted connection line. And because the weighted connection line has distinctions in direction and thickness, by connecting the instruction initiating device and each instruction receiving device with different weighted connection lines, a data interaction network can be obtained with the instruction initiating device as the center and the instruction receiving devices dispersed around the instruction initiating device.

[0122] S4. Confirm the optimal data interaction flow direction according to the data interaction network.

[0123] It should be noted that since the communication ability of the CAT.1 module is relatively weak, if it responds to the requirements of a large number of instruction initiating devices in a short period of time, the CAT.1 module needs to bear a greater communication burden. Therefore, confirming the optimal data interaction flow direction of each instruction initiating device can reduce the communication burden of the CAT.1 module. Specifically, the step of confirming the optimal data interaction flow direction according to the data interaction network includes:

[0124] Calculate the weight judgment value according to the following formula:

[0125] ;

[0126] where represents the weight judgment value of the j-th instruction initiating device, and m is the number of instruction receiving devices;

[0127] Judge the magnitude relationship between the weight of each weight connection line in the data interaction network and the weight judgment value;

[0128] Identify the instruction receiving devices corresponding to the weights less than or equal to the weight judgment value as low-priority devices, and identify the instruction receiving devices corresponding to the weights greater than the weight judgment value as high-priority devices, respectively obtaining a low-priority device set and a high-priority device set. Among them, the CAT.1 module preferentially serves the high-priority device set;

[0129] According to the principle that the CAT.1 module serves bidirectionality first and then unidirectionality, sort each instruction receiving device in the low-priority device set and the high-priority device set respectively to obtain the optimal data interaction flow direction.

[0130] Exemplarily, if the value calculated through the above weight judgment value is 0.5, it means that it is necessary to further judge the magnitude relationship between 0.5 and , that is, sequentially judge the magnitude relationship between 0.5 and the weight of each weight connection line, so as to identify the corresponding instruction receiving device as a low-priority device or a high-priority device.

[0131] Exemplarily, assume that there are 10 low-priority devices in the low-priority device set and 5 high-priority devices in the high-priority device set. Then, among the 10 low-priority devices and 5 high-priority devices, serve each instruction receiving device in turn according to the principle of serving bidirectionality first and then unidirectionality, so as to obtain the optimal data interaction flow direction.

[0132] S5. Based on the optimal data interaction flow direction, use the CAT.1 module to implement data interaction between the instruction initiating device and other instruction receiving devices, so as to achieve the purpose of data interaction among multiple embedded devices.

[0133] It should be explained that the CAT.1 module includes a wireless transmission unit, a modem, a radio frequency front end, and a controller. Among them, the wireless transmission unit is responsible for testing the connectivity of the instruction initiating device, and at the same time is responsible for converting the signal between the instruction initiating device and the instruction receiving device into a wireless signal for transmission. The modem is responsible for modulating and demodulating the wireless signal. The radio frequency front end is responsible for amplifying and filtering the wireless signal. The controller is responsible for executing data interaction between the instruction initiating device and other instruction receiving devices according to the optimal data interaction flow direction. In other words, in the embodiment of the present invention, the optimal data interaction flow direction is transmitted to the controller, and the controller controls the wireless transmission unit, the modem, and the radio frequency front end based on the optimal data interaction flow direction to implement data interaction between the instruction initiating device and other instruction receiving devices, so as to achieve the purpose of data interaction.

[0134] Compared with the problems described in the background technology, the present invention first receives a data interaction instruction initiated by an instruction initiating device and sends the data exchange instruction to the CAT.1 module. Among them, the device type of the instruction initiating device is embedded. Receiving an interaction request from the instruction initiating device indicates the need and starting point of data interaction. Then, determine the type of the data exchange instruction in the CAT.1 module to obtain the instruction type, and determine other embedded devices that may have data interaction with the instruction initiating device according to the instruction type to obtain one or more instruction receiving devices. It can be seen that according to the instruction type, the CAT.1 module can identify other embedded devices that may need to participate in data interaction, which helps to narrow the interaction range and only communicate with relevant devices, improving communication efficiency. Further, obtain the data interaction records between the instruction initiating device and each instruction receiving device in the historical time period, and construct a data interaction network centered on the instruction initiating device according to the data interaction records in the historical time period. Confirm the optimal data interaction flow direction according to the data interaction network, and construct a data interaction network diagram centered on the instruction initiating device using historical data. This network diagram can reveal the connection strength and data flow direction between devices, so as to help the CAT.1 module determine which instruction receiving devices need to be served preferentially, that is, based on the optimal data interaction flow direction, use the CAT.1 module to implement data interaction between the instruction initiating device and other instruction receiving devices, so as to achieve the purpose of data interaction among multiple embedded devices. Therefore, the main purpose of the data interaction method and system for multiple embedded devices based on the CAT.1 module proposed by the present invention is to construct the optimal data interaction flow direction between embedded devices, help the CAT.1 module confirm the service priority of embedded devices, so as to avoid the problem that the CAT.1 module cannot respond in time due to the need to provide data interaction for a large number of embedded devices.
