Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

The embodiment of the application provides a data control method based on a PLC device, and the data control method based on the PLC device can be applied to terminal equipment. The terminal equipment can be equipment such as a computer.

In order to solve the above technical problem, an embodiment of the present application provides a data control method based on a PLC device. By utilizing the data control method based on the PLC equipment provided by the embodiment of the application, the minimum work task closed-loop program is divided into the execution program of the minimum closed-loop action and is kept in a minimum logic block together with the control parameters, a monitoring logic code allowing a real-time variable is added between the program logic blocks between the minimum closed-loop actions for detecting whether the execution of the prior logic block meets the preset trigger condition or not, and the subsequent logic block is triggered to start executing when the preset trigger condition is met, when a certain logic block does not meet the preset trigger condition, the current logic block can control the PLC equipment to pause based on the own safety control strategy, the method is different from the physical brake of an emergency stop button, and the impact of physical safety damage to the PLC equipment is avoided.

Referring to fig. 1, fig. 1 is a schematic flowchart of a data control method based on a PLC device according to an embodiment of the present disclosure. The data control method based on the PLC equipment is applied to terminal equipment. The method may comprise the steps of:

step 101, loading a preset control program, wherein the control program comprises a plurality of logic units which are associated together according to an execution sequence, and inserting a monitoring logic code between two adjacent logic units, and the monitoring logic code is used for detecting whether a preset trigger condition is met or not when the execution of a previous logic unit is finished, and triggering the subsequent logic unit to start executing when the preset trigger condition is met.

In this embodiment, the plurality of logic units may be configured to activate a PLC device, such as a robot arm, to control the robot arm to lift an item from a to a height X, turn clockwise to a position B by an angle Y, and return the robot arm to position a. Wherein each process of the robot arm is controlled by a logic unit. According to the scheme, the control program in the original closed-loop state is disassembled into the execution program of the minimum closed-loop action and is kept in the minimum logic unit together with the control parameters, and the monitoring logic code is inserted between the two adjacent logic units, so that whether the execution of the prior logic unit meets the preset triggering condition when the action is finished can be detected in real time, and the subsequent logic unit is triggered to start executing when the preset triggering condition is met. Once a certain logic unit does not meet the preset triggering condition, the current logic block controls the PLC equipment to pause working based on the safety control strategy of the logic block, the control program is based on an integral closed-loop program, the control program is different from the control program adopted in the prior art, once the program starts to be executed, the complete closed-loop logic is required to be completely executed to be ended, and once the triggering condition is met, the mechanical arm executes control instructions such as clamping, lifting and turning without interruption. In the execution process, when the emergency stop and safety protection active stop control instruction is executed, the execution of a safety interruption program cannot be guaranteed, and generally, physical measures are directly adopted to stop mechanical movement, so that physical impact on equipment can be caused, and the safety of the equipment can be damaged. That is, the prior art lacks a monitoring link for a control node, and cannot perform a self-checking operation once after a process is executed, so that the safety is not high.

And 102, sequentially executing the plurality of logic units according to the execution sequence, and controlling the PLC equipment to suspend working when a certain logic unit does not meet the preset trigger condition.

In this embodiment, a plurality of logic units are sequentially executed according to an execution sequence, execution results of the logic units are monitored simultaneously, and when a certain logic unit does not meet the preset trigger condition, the PLC device is controlled to suspend based on a safety control strategy corresponding to the preset trigger condition.

In some embodiments, the method further comprises:

analyzing the parameter modification request to obtain a control parameter;

and modifying the preset trigger condition according to the control parameter.

In this embodiment, the control parameter in the preset trigger condition is a variable (set to be boolean and default) that can be defined by an external system (i.e., a digital twin system) in real time, and participates in controlling whether to continue with the next minimum action program when the minimum action program logic is executed. The control parameter satisfies the judgment only when necessary conditions are satisfied outside the minimum operation program, and the judgment of the input of the abnormal signal as the protection program is not allowed. The digital twin body carries out the covering treatment under the same control parameter sent out at different time without carrying out the time sequence accumulation control.

The digital twin system carries out real-time parameter change (yes/no) on the control parameters through a system interface (OPC UA, http and other modes), only the latest trigger condition judgment after the parameter change is effected, and the control instruction participates as a necessary incomplete condition for PLC program execution.

In some embodiments, the method further comprises:

In the embodiment, the triggering execution of the subsequent logic unit is controlled after the interval of the preset time length, so that the logic unit has time delay performance, the execution of the equipment after the inertia release is allowed, and the physical safety damage of the equipment is greatly reduced.
