[0030] Reference Figure 1 , a Modbus to LoRaWAN communication method, system, terminal and storage medium of the present invention provide a Modbus to LoRaWAN communication method, such as Figure 1 As shown, the Modbus to LoRaWAN communication method includes: S1. Obtain real-time data information of the electronic device corresponding to the modbus device; S2. Constructing a device collection description table according to the real-time data information; S3, the transit gateway constructs a virtual device mapping table according to the device collection description table; S4, generating summary data information according to the virtual device mapping table; S5. Send the summary data information to a remote server using LoRaWAN technology.

[0031] In this embodiment, the technical solution first obtains the real-time data information of the electronic device corresponding to the modbus device, which is conducive to improving the efficiency of remote monitoring and management; then, a device collection description table is constructed according to the real-time data information, and the transit gateway constructs a virtual device mapping table according to the device collection description table, so as to achieve rapid data collection and be applicable to more types of Modbus devices; then, summary data information is generated according to the virtual device mapping table, and finally, the summary data information is sent to the remote server in the form of LoRaWAN technology, so as to be applicable to more types of Modbus devices and their different parameter collections, and realize the Modbus to LoRaWAN communication mode, thereby simplifying the construction process, and improving the integration and flexibility of the system; and can improve the efficiency of remote monitoring and management.

[0032] Specifically, in some implementations, in S1, the step of obtaining real-time data information of the electronic device corresponding to the modbus device includes the following: Divide the area according to the types and environments corresponding to all the modbus devices to form at least two supervision areas; The modbus device is used to obtain real-time data information of the electronic equipment in the supervision area; wherein the real-time data information includes device address, register address, etc.

[0033] That is to say, since Modbus devices are deployed in a dispersed manner and at long distances, it is necessary to divide all Modbus devices into regions according to their types and environments. Then, the Modbus devices are used to obtain real-time data information of electronic equipment in the regulatory area, thereby achieving regional management, improving the rationality and efficiency of supervision, and effectively solving the problem of difficult and high cost of scene wiring. Among them, regional division is carried out according to the environment: the distance difference between the Modbus device and the corresponding transit gateway is used to divide the far and near areas. The Modbus devices in the closer areas (divided according to actual needs) implement a single-level transit gateway (i.e., one transit gateway); the Modbus devices in the farther areas (divided according to actual needs) implement a multi-level transit gateway (at least two transit gateways perform LoRaWAN communication to shorten the single transmission distance; or each transit gateway at the multiple levels can also be directly connected to the remote server for communication, and a single transmission is also performed between the two transit gateways).

[0034] Specifically, in some implementations, in S2, the step of constructing a device collection description table according to the real-time data information includes the following: The modbus device performs classification and analysis according to the real-time data information to form corresponding real-time description items; Transmitting the real-time description item to the transit gateway via LoRaWAN technology or RS485 interface technology; When the sum of the number of real-time description items and past description items reaches the first preset total number, a new device collection description table is rebuilt. The first preset total number is 100. Figure 4 As shown, the transit gateway controls the modbus device to collect and summarize the device address, register address, number of variables and data type of the corresponding electronic device according to the actual needs of the on-site equipment and in accordance with the rules to form the corresponding real-time description items; the real-time description items are transmitted to the transit gateway through LoRaWAN technology or RS485 interface technology to complete the configuration work. And when the sum of the number of real-time description items and past description items reaches 100 description items, the modbus device needs to construct a new device collection description table for more than 100 real-time description items and past description items, thereby improving the integration and flexibility of the system, reducing excessive communication burden; and can improve the efficiency of remote monitoring and management. For detailed content of the device collection description table and description items, see Figure 4 and Schedule 1.

[0035] Table 1 Specifically, in some embodiments, Figure 2 and 3As shown, the transit gateway includes an MCU component 1, an RS485 interface 2, a LoRaWAN interface 3, a power supply component 4 and a USB interface 5; one end of the RS485 interface 2 is electrically connected to the MCU component 1; the other end of the RS485 interface 2 is electrically connected to the Modbus device; the LoRaWAN interface 3 is electrically connected to the MCU component 1; the LoRaWAN interface 3 is used for communication connection with the remote server; one end of the USB interface 5 is electrically connected to the MCU component 1; the other end of the USB interface 5 is used for communication connection with the remote server or for electrical connection with the power supply component 4 (having a USB interface 5, such as a TYPE-C interface; can be used for power supply or communication configuration). The USB interface 5 is a TYPE-C interface. The power supply component 4 uses a power supply or a battery for on-site power supply; and the voltage used by the power supply or battery is a 5-24V power supply system. That is to say, the RS485 interface can be used to communicate with the modbus device to collect the data of the modbus device, and the wireless LoRaWAN interface can be used to send the collected data to the remote server. Therefore, due to its wireless characteristics, the communication distance can be as long as several kilometers or even more than ten kilometers, eliminating the problem of wiring. In turn, it can simplify the construction process, improve the integration and flexibility of the system, and improve the efficiency of remote monitoring and management.

[0036] Among them, the Microcontroller Unit (MCU), also known as a single-chip microcomputer or a single-chip microcomputer, appropriately reduces the frequency and specifications of the central processing unit (CPU), and integrates peripheral interfaces such as memory, timer, USB, A / D conversion, UART, PLC, DMA, and even LCD drive circuits on a single chip to form a chip-level computer, which can perform different combination controls for different application scenarios.

[0037] Specifically, in some implementations, in S3, the step of the transit gateway constructing a virtual device mapping table according to the device collection description table includes the following: The transit gateway reads and parses the data corresponding to the device collection description table; The transit gateway makes a mirror copy of the data corresponding to the device acquisition description table to form the virtual device mapping table. In other words, in order to ensure the authenticity and accuracy of the data and to provide a unified and standardized data structure to the outside, a mirror copy is required to form the virtual device mapping table. That is, this application document collects electronic devices through the modbus device and transmits them to the outside through the wireless LoRaWAN interface to realize an efficient communication method from Modbus to LoRaWAN, thereby maintaining the technical advantages of LoRaWAN while improving communication efficiency and data processing capabilities.

[0038] The step of forming the virtual device mapping table includes the following: When the sum of the number of real-time mapping items and previous mapping items in the virtual device mapping table reaches the second preset total number, a new virtual device mapping table is rebuilt. The second preset total number is 100. Figure 5 As shown, the transit gateway records the device address, register address, number of variables and data type of the corresponding electronic device, collects and summarizes them according to the actual needs of the on-site equipment and the rules to form the corresponding real-time mapping items; the detailed virtual device mapping table and the content of the real-time mapping items or the previous mapping items can be seen in Figure 5 And Table 1.

[0039] Among them, in some implementations, the step of the transit gateway reading and parsing the data corresponding to the device collection description table includes the following: The transit gateway generates a verification instruction to the original modbus device to perform a verification operation; The original modbus device retransmits the real-time description item corresponding to the device acquisition description table to the transit gateway to form a preliminary verification result; The original modbus device re-collects the same type of data of the electronic device corresponding to the original modbus device to generate re-data; Comparing the re-data with the real-time description item corresponding to the device acquisition description table to form a re-verification result; Compare the secondary data with the real-time description items corresponding to the device acquisition description table to form a third verification result; When the preliminary verification result, the second verification result and the third verification result are all consistent, the mirror copy step can be performed. In other words, in order to avoid errors and the like during the transmission process, multiple verification operations need to be performed to improve monitoring management efficiency.

[0040] Wherein, in some embodiments, the transit gateway generates a verification instruction to the original modbus device to perform the verification operation, including the following steps: Determine the actual number of times and actual duration that the transit gateway receives the data corresponding to the device collection description table; When the actual number of times reaches the preset number of times (which can be 200 times, 300 times, 350 times, etc.), and the actual duration reaches the preset duration (which can be 1h, 2h, 10h, etc.), a verification instruction is generated to the original modbus device to perform the verification operation; When the actual number of times is less than the preset number of times (which can be 200 times, 300 times, 350 times, etc.), and the actual duration is less than the preset duration (which can be 1h, 2h, 10h, etc.), the transit gateway will perform a mirror copy of the data corresponding to the device collection description table. This method implements a sampling verification method to ensure the accuracy of the data and the speed and efficiency of communication.

[0041] Specifically, in some implementations, in S4, the step of generating summary data information according to the virtual device mapping table includes the following: Constructing a reporting trigger rule table according to the virtual device mapping table; wherein each mapping item in the virtual device mapping table is mirrored to form each corresponding rule item in the reporting trigger rule table; When the sum of the number of rule items in the reporting trigger rule table reaches a third preset number (for example, 100, 200, etc.), it is considered that the trigger condition is met; At the same time, all rule items in the reporting trigger rule table generate summary data information. In other words, in order to overcome the technical problems of low communication rate of LoRaWAN wireless technology and slow response of traditional polling method, it is necessary to build a reporting trigger rule table formed by a certain number of rule items; this table needs to be generated by users according to the actual needs of the site and in accordance with the rules; and then complete the configuration work through LoRaWAN wireless or USB interface.

[0042] Among them, there can be up to 100 rule items in the reporting trigger rule table, and one rule item will include the device address, register address, judgment condition and two variable parameter items. Here, one rule item can make a real-time judgment on whether the data in a mapping item in the virtual device mapping table meets the trigger condition. For example, in a rule item, the device address is 1, the register address is 0x1000, the judgment condition is "report when greater than a certain value", parameter 1 is 35, and parameter 2 is 60. It means that for a device with a modbus device address of 1, if the data value at its register 0x1000 is greater than 35, data reporting will be triggered, and the shortest reporting cycle is 60s. Therefore, there can be up to 100 rule items in the reporting trigger rule table, and one rule item will include the device address, register address, judgment condition and two variable parameter items. Here, one rule item can make a real-time judgment on whether the data in a mapping item in the virtual device mapping table meets the trigger condition. For example, in a rule item, the device address is 1, the register address is 0x1000, the judgment condition is "report when greater than a certain value", parameter 1 is 35, and parameter 2 is 60. It means that for a device with a modbus device address of 1, if the data value at register 0x1000 is greater than 35, data reporting will be triggered, and the shortest reporting cycle is 60s. With these rules, key data can be monitored and once exceeded, reporting will be triggered to achieve timely response instead of mindless periodic reporting that occupies wireless resources in vain. For detailed reporting trigger rule table and rule item contents, see Figure 6 and 7 shown.

[0043] The invention also discloses a Modbus to LoRaWAN communication system.

[0045] In addition, an embodiment of the present invention further provides a computer-readable storage medium, on which a Modbus-to-LoRaWAN communication program is stored. When the Modbus-to-LoRaWAN communication program is executed by a processor, the following operations are implemented: Get the real-time data information of the electronic device corresponding to the modbus device; Constructing a device collection description table according to the real-time data information; The transit gateway constructs a virtual device mapping table according to the device collection description table; Generate summary data information according to the virtual device mapping table; The aggregated data information is sent to a remote server via LoRaWAN technology.
