Serial port online simulation debugging system applied to controller and method thereof

Abstract

The invention provides a serial port online simulation debugging method applied to a controller, comprising: step 102 for recording the coordinate position of every network in a plurality of networks; step 104 for searching and comparing the coordinate position of every network in a plurality of networks to determine the displayed network; step 106 for determining parameters to be displayed for the simulation debugging in the displayed network; step 108 for notifying the parameters to the controller by a serial port simulation protocol. When an engineering vehicle general controller is treated by the serial port online simulation debugging, a computer PC captures a snapshot of all element data to be displayed between an initial network number and an end network number displayed on a current screen for one time snapshot within 0.5s by the window screen technology. Thus, the data amount sent by the serial port is reduced greatly. Simultaneously, the simulation display realizes the function of being synchronous with the operational result of the engineering vehicle general controller, solves the fuzzy simulation data problem during the online debugging and overcomes the inaccurate simulation data problem caused by the slow data transmission of the serial port.

Description

technical field [0001] The invention relates to a simulation debugging technology, and more particularly relates to a serial port online simulation debugging system and method for a controller. Background technique [0002] In the application field of engineering vehicle controllers, online debugging and simulation operations are usually performed. During the online debugging and simulation process, it is necessary to transmit the operating data of all networks of the ladder diagram through the serial port. If the program volume is large, the amount of data transmitted through the serial port is particularly large. The online debugging simulation is severely distorted, and the actual running data is slow to respond. Therefore, there is a demand for a novel serial port online emulation debugging system and method for a controller. Contents of the invention [0003] In order to solve at least one of the above-mentioned technical problems, the present invention provides a se...
