The data acquisition system or gateway is responsible for reading data from the MODBUS device. Therefore, it is necessary to configure the data acquisition channel and point according to the point table information provided by the manufacturer; S2. Create product, device and object models for the target MODBUS device on the IoT platform based on the point table information of the target MODBUS device, and bind them to the mapping relationship with the point information of the target MODBUS device for data collection; Among them, creating product, device and object models for the target MODBUS device, as well as binding mapping relationships, and establishing associations are carried out in the background management system of the IoT platform or a special configuration tool. The IoT platform needs to understand the characteristics and data format of the MODBUS device in order to correctly display and control these devices on the platform. Therefore, it is necessary to build corresponding product, device and object model information on the IoT platform based on the MODBUS point table information; and by binding the product, device and object model information on the IoT platform with the data collection points, it can be ensured that the data read from the MODBUS device can be correctly mapped to the device model on the IoT platform; S3. Read data from the target MODBUS device according to the bound mapping relationship, and then store it according to the pre-set storage strategy; Among them, the storage of data involves the data storage component of the IoT platform or an external database system. The IoT platform needs to store the data read and converted from the target MODBUS device for subsequent analysis, processing and display. The database system for storing data can be the IoT platform itself or externally integrated. S4. Convert the read target MODBUS device data into standard data recognizable by the IoT platform; Among them, data conversion is carried out in the data acquisition system, data gateway or data processing component of the Internet of Things platform. The purpose of data conversion is to convert the MODBUS data format into a standard data format that can be recognized by the Internet of Things platform. The converted data can be directly reported to the Internet of Things platform for subsequent use.

[0025] In this embodiment, the device data is collected by the MODBUS protocol and the data in the MODBUS can be converted into a standard data format of the Internet of Things platform, so that the data in the standard format is reported to the cloud platform.

[0026] Further, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process in this embodiment, another method for collecting MODBUS device data based on the Internet of Things platform is provided, such as Figure 2 As shown, the method comprises the following steps: The specific steps of step S1 are as follows: S11 obtains the point table information of the target MODBUS device from the manufacturer, the point table information includes the register address, data type and scaling factor of the target MODBUS device; For example, take a temperature and humidity sensor using the MODBUS protocol as an example, and its data needs to be connected to an IoT platform. The MODBUS point table information of the sensor is as follows: Temperature (register address: 40001, data type: 16-bit integer, scaling factor: 0.1); Humidity (register address: 40002, data type: 16-bit integer, scaling factor: 0.1); S12. Customize the channel name for the target MODBUS device according to the point table information of the target MODBUS device, select the MODBUS protocol, and configure the IP address and port corresponding to the MODBUS host to complete the MODBUS channel information configuration for data collection; Exemplarily, the following steps are used to configure the MODBUS channel information for the temperature and humidity sensor using the MODBUS protocol: Custom channel name: temperature and humidity sensor channel; Select MODBUS protocol; Configure the MODBUS host IP address: 192.168.1.100, port: 502; S13. Use the collector to configure the target MODBUS device for data collection based on the point table information of the target MODBUS device; The specific steps of step S2 are as follows: S21. Create a product name for the target MODBUS device, import object model attributes according to the point table information of the target MODBUS device, and then set the storage strategy according to the storage requirements; For example, create a product name for a temperature and humidity sensor using the MODBUS protocol: Create product name: Temperature and humidity sensor product; Import object model attributes: temperature (data type float), humidity (data type float); Set storage strategy: store at time intervals, with an interval of 1 minute; S22.

Establish a binding mapping relationship between the physical model of the target MODBUS device and the point information of the target MODBUS device for data collection; For example, create an object model for a temperature and humidity sensor using the MODBUS protocol and bind the mapping relationship: Combined with the point table information of the target MODBUS device, enrich the object model information: temperature (float), humidity (float); Binding mapping relationship: Temperature (physical model attribute) -> Temperature (collector point); Humidity (object model attribute) -> Humidity (collector point); The specific steps of step S3 are as follows: S31 query the storage strategy of the product attributes of the target MODBUS device; S32. According to the mapping relationship between the target MODBUS device's point information and the product, device, and object model binding, and using the configured MODBUS channel information to read data from the target MODBUS device; S33. The data of the target MODBUS device read is saved according to the storage strategy; Exemplarily, save the target MODBUS device data to internal storage: Query the storage scheme configured: store at time intervals, with an interval of 1 minute; Store device data according to the storage plan: store temperature and humidity data every 1 minute; The specific steps of step S4 are as follows: S41. Create a JSON object for the target MODBUS device and set the device properties with field values ​​empty for the target MODBUS device in the JSON object; For example, construct an empty JSON object for a temperature and humidity sensor using the MODBUS protocol: json { "temperature": null, "humidity": null }; S42. Obtain the stored data according to the mapping relationship between the target MODBUS device's point information and the product, device, and object model binding, fill it into the device properties of the JSON object, and complete the MODBUS device data collection; According to the binding mapping relationship, fill the corresponding data into the JSON object position: Assuming that the original temperature value read from the MODBUS device is 2500 (16-bit integer) and the original humidity value is 5000 (16-bit integer), the converted data is: json { "temperature": 250.0, / / 2500 * 0.1 = 250.0 "humidity": 500.0 / / 5000 * 0.1 = 500.0 }.

[0027] Through the implementation of the above steps, the temperature and humidity sensor data using the MODBUS protocol is converted into the standard book required by the Internet of Things platform, and the data reporting and storage are realized.

[0028] In an embodiment of the present invention, based on S13, a possible embodiment will be given below to illustrate its specific implementation scheme in a non-limiting manner.

[0029] The specific steps of step S13 are as follows: S131. Select the MODBUS channel for the target MODBUS device, customize the collector name, select the fault handling method, set the device data timeout, and set the MODBUS slave address; S132. According to the point table information of the target MODBUS device, create a point name, select a function code, enter the point address, set the scaling factor, set the access type, and set the acquisition frequency; For example, configure the point information for the temperature and humidity sensor using the MODBUS protocol: Select the channel information: temperature and humidity sensor channel; Custom collector name: temperature and humidity collector; Select the fault handling method: Retry; Set device data timeout: 10 seconds; Set slave address: 1; Create point information: Temperature: function code 03, register address 40001, scaling factor 0.1, access type read, acquisition frequency 10 seconds; Humidity: Function code 03, register address 40002, scaling factor 0.1, access type read, acquisition frequency 10 seconds.

[0030] In an embodiment of the present invention, based on step S42, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0031] The specific steps of step S42 are as follows: S421. Obtain the saved data of the target MODBUS device and verify whether it is within a reasonable range after scaling according to the corresponding scaling factor; If yes, go to step S422; If not, record an error log; S422. Fill the target device scaled data into the field value of the corresponding device attribute of the JSON object; For example, a temperature and humidity sensor with a switch provides the following data points: Temperature (register address: 40001, data type: int16, scaling factor: 0.1) Humidity (register address: 40002, data type: uint8, no scaling required) Device status (register address: 40003, data type: bit, indicating on / off); Create a physical model with the following properties on the IoT platform: temperature (temperature, data type: float) humidity (data type: int) status (status, data type: boolean) The specific data reading process is as follows: Read the value of register 40001 from the MODBUS device. Assume that the original value read is 1234 (int16). Read the value of register 40002 from the MODBUS device, assuming the original value read is 50 (uint8); Read the value of register 40003 from the MODBUS device, assuming that the original value read is 1 (bit, 1 means on); The data parsing and verification process is as follows: Parse and validate the temperature value: Multiply 1234 (int16) by the scaling factor 0.1 to get 123.4. Verify that the value is within a reasonable range (for example, between -50 and 150). Parse and verify the humidity value: Use 50 (uint8) directly and verify that the value is within a reasonable range (for example, between 0 and 100); Parse and verify the status value: parse 1 (bit) as true (indicates on); Data formatting: json { "temperature": 123.4, / / Multiply 1234 (int16) by 0.1 to get 123.4 and fill it into the temperature field "humidity": 50, / / Use 50 (uint8) directly and fill it into the humidity field "status": true / / Parse 1 (bit) as true and fill it into the status field } Data reporting: Report the formatted JSON object to the IoT platform.
