Abstract
The embodiment of the invention discloses a programmable control system and method and relates to the technical field of programmable control. The invention aims to solve the deficiencies of a complicated manufacturing process, few output points and a large occupied area of a programmable logic controller in the prior art. The programmable control system comprises a plurality of light emitting units, an optical signal control unit used for generating illumination control signals of the light emitting units according to a control logic of a controlled unit, a photosensitive unit used for acquiring optical signals outputted by the light emitting units and converting the optical signals into corresponding electrical signals, and a control signal output unit which is used for generating a control signal of the controlled unit according to the electrical signal. The programmable control system of the invention has the advantages of reasonable structure, multiple output points of the controlsignal and high overall integration.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of programmable control, and in particular to a programmable control system and method. Background technique [0002] Programmable logic controller is a digital operation electronic system specially designed for application in industrial environment. It uses a programmable memory to store instructions for performing logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production through digital or analog input and output. process. [0003] Existing programmable controllers generally obtain one control signal through multi-level gate circuits. When the controlled terminal has multiple control points, and the control signal of each control point is changeable and complex, then the programmable control The operation program of the gate circuit of the device and the circuit structure of the gate circuit ...
