Control system and method realizing multiple-input-multiple-output function

Abstract

The invention relates to the field of input and output control and especially relates to a control system and method realizing a multiple-input-multiple-output function. The control system is provided with a plurality of input ends, a plurality of output ends and a plurality of parallel programmable time delay modules. The control method is characterized in that a triggering signal and an output end are preset for each programmable time delay module, the plurality of input ends are enabled to be connected with each programmable time delay module and be corresponding to one or one output end. According to the invention, the output logic of an embedded system can be changed at any time, the input signals and the output ends are not in a fixed link relation any longer, the flexibility of the output modes is enhanced, and the design purpose of multiple-input-multiple-output crossed outputting is achieved; in addition, when a user faces different output driving requirements, the change of software codes is not needed, and the output logic can be changed at any time by only changing triggering signals and output end preset to the programmable time delay modules, so that field programmable logic control can be rapidly realized.

Description

technical field [0001] The invention relates to the field of input and output control, in particular to a control system and method for realizing multiple inputs and multiple outputs. Background technique [0002] The embedded software of the existing control system usually adopts three ways to process the output: [0003] Method 1: as figure 1 As shown in the flow chart of the single-input single-output control method, the input of the signal directly triggers the output, that is, "one-to-one output". [0004] Method two: as figure 2 As shown in the flow chart of the multi-input single-output control method, the input signal triggers the set output according to the programmed output index, that is, "many-to-one output" (multiple event states can be programmed to be the same trigger output). [0005] Method three: as image 3 As shown in the flow chart of the single-input multiple-output control method, the output accepts the set input signal and triggers the output acc...

Problems solved by technology

[0008] Method 2: Through programming, multiple input signals can be used to trigger the output of the same output terminal; the requirements for certain functions can be realized through programming without changing the software code, but the same input signal cannot be used to trigger multiple outputs

[0009] Method 3: The same input signal can be used to trigger multiple outputs through programming; the requirements for certain functions can be realized through programming without changing the software code, but it is impossible to achieve multiple input signals triggering the same output
