Embodiment

[0071] Such as image 3 , the test object is a kind of lifting mechanical equipment in the process of preparation, assuming that ABC is the base of the equipment, AG is the mechanical arm of the equipment, CD is the hydraulic cylinder support arm of the equipment, and a heavy object is hung at point G through a wire rope.

[0072] The purpose of control is that the AG mechanical arm moves up and down around point A through the expansion and contraction of the CD hydraulic cylinder support arm, and at the same time lifts and transports heavy objects up and down.

[0073] In order to meet the stability and reliability of heavy objects in the process of up and down transportation, the following control requirements are required for the lifting equipment: the movement speed of the AG mechanical arm is proportional to the input of the operating handle; smooth acceleration and deceleration; deceleration before reaching the highest point and the lowest point, Stop the movement after ...

Abstract

The invention discloses a method for an auxiliary test of a PLC control program by employing an equipment virtual prototype. The method includes steps: step 1, programming is performed, the programming relates to four programs, wherein an equipment virtual prototype program, an OPC client program, and a PLC control program are required to be programmed, an OPC server program employs the OPC server program provided by a manufacturer of a PLC controller, and only corresponding communication data configuration is needed; step 2, hardware, a PLC control system, a PC, and a communication network are established, and the PLC control system and the PC are connected to the Internet via a communication card; step 3, program installation and communication configuration are realized; and step 4, the program is tested, and then modified and optimized according to the test result. According to the method, the cost and time for individually making a three-dimensional model are reduced, and the security of the test of the PLC control program can be improved.

Description

technical field [0001] The invention belongs to the technical field of program testing, and relates to a method for assisting testing of PLC control programs by using a virtual prototype of equipment. Background technique [0002] At present, CAE / CAD / CAM programming platforms such as UG and SolidWorks are used to assist the design and manufacture of mechanical equipment. The control systems equipped mostly use PLC as the controller, and the correctness and rationality of the PLC control program are directly related to the safety of the product. and aging. At present, for the control function test and verification of the program, it is still generally used to test the control function directly on the actual product. However, when the product is in the testing stage of mechanical, electrical, and hydraulic joint debugging, there may be errors in logic control and motion control algorithms in the written PLC control program, resulting in misoperation of the equipment, so there...
