Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0039] The present invention proposes a design method for a data acquisition device. Figure 1 is a flow chart of a method 100 for designing a data acquisition device according to an embodiment of the present invention. Figure 1 As shown, the design method 100 includes:

[0040] Step 110, initializing a data acquisition device, in which a runtime environment of a first programming language is burned.

[0041] The data acquisition device can be a collection gateway or an edge device. The collection gateway and edge device are deployed at the factory site to collect data. After the collected data is processed and analyzed, the factory site can be used for status monitoring and predictive maintenance, thereby realizing the digitization of the factory. Initialize the data acquisition device, that is, perform initial configuration on the data acquisition device. The data acquisition device is burned with a runtime environment of the first program language, and the function files developed by the first program language can be directly run in the runtime environment in an interpreted execution manner without compilation. In some embodiments, the first program language can be Python or Java Script. Accordingly, the runtime environment can be a Python runtime environment and a Node.js runtime environment.

[0042] In some embodiments, initializing the data acquisition device includes: loading a basic service program on the data acquisition device, configuring connection parameters, and establishing a connection between the data acquisition device and the file server according to the connection parameters. Specifically, the basic service program may include programs corresponding to basic functions of the gateway, such as a gateway configuration module, a network connection jump, local data buffering, data processing, data upload services, and file management services. By loading the basic service program, the data acquisition device has basic functions such as a network connection jump, local data buffering, and data processing; establishing a connection between the data acquisition device and the file server, so that the data acquisition and the file server can communicate according to the set protocol. To this end, by initializing the data acquisition device, the data acquisition device is equipped with basic functions and connection capabilities.

[0043] Figure 2 is a schematic diagram of a data acquisition system 20 according to an embodiment of the present invention. Figure 2 As shown, the data acquisition system 20 includes a plurality of data acquisition devices 21 and a file server 22 connected to the plurality of data acquisition devices 21. It is understandable that the data acquisition system 20 may include more data acquisition devices 21. The data acquisition device 21 includes a basic function module 211 and a file management module 212. The basic function module 211 endows the data acquisition device 21 with basic functions such as network hopping, local data buffering, and data processing. The file management module 212 may receive files from the file server 22 through a connection established with the file server 22. The basic service program may include a basic function module 211 and a transceiver 214.

[0044] Step 120, the data acquisition device obtains a configuration file and a function file from a file server, where the function file is developed using a first programming language.

[0045] The configuration file can be generated by a configuration tool, and the configuration file is used to configure the connection parameters and communication parameters required by the data acquisition device. The function file is developed in the first program language, and the function file can realize corresponding functions after running, such as data acquisition protocol, data upload protocol, data processing function, etc. The function file developed in the first program language can be directly run in the runtime environment in an interpreted execution mode without compilation.

[0046] In some embodiments, the data acquisition device obtains configuration files and function files from a file server, including: determining an acquisition cycle, and the data acquisition device obtains the configuration files and function files from the file server according to the acquisition cycle. The file suffix of the configuration file may be .cfg, and the suffix of the function file may be .py. The configuration files and function files may be identified by identifying the suffixes, thereby periodically obtaining the configuration files and function files. To this end, by obtaining the configuration files and function files from the file server according to the acquisition cycle at the data acquisition device, the file acquisition process is simplified.

[0047] In some embodiments, the data acquisition device obtains configuration files and function files from a file server, including: monitoring the file server, and when a new function file is detected in the file server, obtaining the new function file from the file server. For example, when a new file with a suffix of .cfg or .py is detected in the file server, it is determined that there is a new function file in the file server, and the new function file is obtained from the file server. To this end, by monitoring the file server, and when a new function file is detected in the file server, the new function file is obtained from the file server, the efficiency of file acquisition is improved and system resources are saved.

[0048] Step 130, reading configuration information from the configuration file, and loading the function file in the runtime environment according to the configuration information, so that the data acquisition device executes the function corresponding to the function file.

[0049] Configuration information may include points, device IP ports, etc. After obtaining the configuration file and function file, stop the original function in the data acquisition device, load the function file in the runtime environment according to the configuration information in the configuration file, and after loading, the data acquisition device can have the function corresponding to the function file. By deploying the runtime environment in the data acquisition device, the operation of the function file does not need to rely on the underlying hardware, that is, the isolation of the function file and the underlying hardware is achieved. For the data acquisition device, you only need to obtain the newly developed function file and load it in the runtime environment to enable the data acquisition device to achieve functional expansion, which improves the flexibility of the data acquisition device function expansion.

[0050] refer to Figure 2 Taking the first programming language as Python as an example, the file management module 212 obtains the configuration file .cfg and the function file .py from the file server 22, loads the Python function file .py in the Python runtime environment 213, and collects data for the device according to the configuration file .cfg, so that the data collection device 21 has the function corresponding to the Python function file. After the data collection device 21 processes the data using the extended function, it uploads the data to the cloud 23 through the transceiver 214.

[0051] In some embodiments, configuration information is read from a configuration file, and a function file is loaded in a runtime environment according to the configuration information, so that the data acquisition device executes the function corresponding to the function file, including: the data acquisition device adds a data acquisition protocol, a data upload protocol, or a data processing function after executing the function file. Exemplarily, the data acquisition protocol can be Modbus, S7 protocol, etc., the data upload protocol can be MQTT protocol, and the data processing function can be data cleaning, data screening, and data aggregation, etc. To this end, the expansion of the data acquisition protocol, data upload protocol, and data processing function of the data acquisition device is realized.

[0052] The embodiment of the present invention provides a design method for a data acquisition device, which deploys a runtime environment in the data acquisition device so that the operation of the function file does not need to rely on the underlying hardware and operating system, that is, the isolation of the function file from the underlying hardware or operating system is achieved. For the data acquisition device, it only needs to obtain the newly developed function file and load it in the runtime environment to enable the data acquisition device to achieve functional expansion, thereby improving the flexibility of the data acquisition device's functional expansion.
