[0002] PLC (Programmable Logic Controller) is an electronic system that operates digital computing operations and is designed for use in industrial environments. It collects data from equipment (such as sensor readings, equipment status, etc.) and transmits this data to external systems through communication interfaces. At the same time, it controls external equipment (such as start, stop, speed regulation, etc.) based on internally stored programs.

[0003] At present, the main PLC equipment manufacturers on the market include Siemens and Schneider of Germany, Omron and Mitsubishi of Japan, etc. They generally use 16-32 bit processors, and the signal input and output are realized by the IO port to collect various sensor signals. The communication management interface with the monitoring system mostly adopts the modbus protocol. However, there are more and more sensors integrated in various modern on-site equipment, and many intelligent devices no longer provide IO port access, but use various communication interfaces such as 485, RJ45, CAN, etc. to realize data collection and equipment control.

[0020] Embodiment of equipment automatic control system based on edge computing gateway The present embodiment provides a device automatic control system based on an edge computing gateway. The system uses a configuration interface to display preset data input and output terminal identifiers, different primitive templates corresponding to control instructions, and configuration parameters of the primitive templates corresponding to each logic instruction in the control instruction, so that the user can configure the input and output data of the automatic control logic of the device connected to the gateway according to the identifier; and enables the user to select the corresponding primitive template and set the value of the configuration parameter of the logic instruction in combination with the configured input and output data to configure the automatic control logic process of the gateway; the system then uses a configuration generation module to read the corresponding primitive template and the value of its configuration parameter selected through the configuration interface, obtain the corresponding control instruction, and generate a configuration document corresponding to the automatic control logic process. The device automatic control system based on the edge computing gateway solves the problem that the existing PLC devices that complete signal acquisition and device control by their own devices are difficult to implement sampling and control of the current intelligent devices that do not provide IO port access, so that the edge computing gateway including the device automatic control system can meet the communication with devices of various types of communication interfaces, and performs data sampling and control on the devices that establish communication connections through the configuration file generated by the control module in the device automatic control system parsing the configuration file generated by the configuration generation module.

[0021] The device automatic control system based on the edge computing gateway specifically includes: a configuration interface, a configuration generation module, a communication management module and a control module in the edge computing gateway; the configuration interface is used to display at least one of the preset data input terminals of the device switch quantity and analog quantity input signals and their identifiers and at least one of the data output terminals of the device switch quantity and analog quantity output signals and their identifiers, so that the user can select the corresponding identifier to configure the input and output data of the automatic control logic of the device connected to the gateway; it is also used to display different primitive templates corresponding to preset different management instructions and logic instructions and the configuration parameters of the primitive templates corresponding to each logic instruction, so that the user can select the corresponding primitive template and set the value of the configuration parameter of the logic instruction in combination with the input and output data of the automatic control logic of the device of the configured gateway to configure the automatic control logic process of the device of the gateway; The configuration generation module is used to read the corresponding primitive template and the value of its configuration parameters selected through the configuration interface, obtain the corresponding control instructions, and generate the configuration file corresponding to the automatic control logic process of the device of the gateway; the communication management module is used to collect the input data of the automatic control logic; the control module is used to parse the configuration file, run the control instructions of the configuration file according to the input data of the automatic control logic, and send the operation instructions generated when the control instructions of the configuration file are run to the corresponding device through the communication management module according to the output data of the automatic control logic; Logical instructions include: conditional instructions for conditional judgment and processing using input data and connecting arrow instructions for indicating the order of instruction execution; management instructions are used to control the execution status of tasks containing logical instructions.
