Automatic test system and method for industrial production process control logic

Abstract

The invention discloses an automatic test system and method for industrial production process control logic, and belongs to the technical field of industrial control. The system is composed of a test basis information setting module, an input signal generation module, a data collection module and a comparison and determination module. Test data generated by a numerical value signal input module are used as the input of the tested control logic. The method comprises the steps that signals from [0,0,0...0] to [1,1,1...1] and signals from [1,1,1...1] to [0,0,0...0] are sequentially input for the tested control logic automatically, whether the tested control logic is correct or not is automatically judged according to output signals which are sequentially and correspondingly generated, the signals input every time, the corresponding output signal and the test conclusion are recorded, the ergodicity of the control logic test can be achieved, control logic errors can be automatically recognized, and the automatic test system and method have the advantages of being high in credibility, repeatable, traceable and high in efficiency and accuracy.

Description

technical field [0001] The invention belongs to the technical field of industrial control, and in particular relates to an automatic test system and method for control logic of an industrial production process. Background technique [0002] The automatic control system of industrial production process usually has a complex structure and contains a large number of control logics. These control logics perform key functions such as equipment protection, production process interlocking, safety protection of personnel and the environment, fault handling and emergency shutdown, and their organic linkage constitutes a complete industrial automatic control system. [0003] For all control systems, the design and testing of control logic are key links, which are related to the safe operation of the entire production process. At present, most industrial automatic control systems use digital devices, namely Programmable Logic Controller (PLC) or Distributed Control System (Distributed...

Problems solved by technology

Due to the wide variety of input conditions and complex logical relationships, manual testing not only requires a lot of work and takes a long time, but also has the problem of whether it is possible to traverse all control logic, resulting in potential false detection and missed detection risks, and may be damaged due to control logic errors Equipment, in severe cases, will endanger the environment and life safety, and bring huge technical risks and hidden safety hazards to the operation of the system
