Programmable control module based on SCM

Abstract

This is a kind of programmable control module based on the singlechip. It comprises a printed circuit board, shell body, and the leading feet. There weld and equip the singlechip, the restoration circuit, the data storage circuit, the A/D circuit, the D/A circuit, the coupling input isolation driving circuit, the coupling output isolation driving circuit, the second serial communication circuit. The printed circuit board is sealed in the shell body. Several metal leading feet of the leading feet are welded in the printed circuit board and extended out of the shell body. The module software are programmed in the trapeziform figure wise, so that the user just need to weld the programmable module on his/her designed printed circuit board. There assembled simple electronic organ around the periphery to complete the hardware design. The module adopts the trapeziform figure software programming. It's very convenient to be exploit for users. Besides it has a lower cost, a small volume and is agile to use.

Description

technical field [0001] The invention relates to a programmable control device, in particular to a programmable control module based on a single-chip microcomputer. Background technique [0002] Nowadays, industrial control generally has two modes: single-chip control and programmable logic controller (PLC). Using the language circuit of the single-chip microcomputer, such as assembly language, C language, etc. to program, the advantage of this is low cost and high flexibility, but the disadvantage is that the workload is large and the development cycle is long. Now there are some programmable controllers (also known as PLCs) on the market. Called PLC), its characteristic is that the hardware has been completely done by the manufacturer, and the designer only needs to connect the PLC with peripheral contactors and other electrical components. Its software is generally completed in the form of ladder diagrams. The assembly language of this microcontroller, The C language is s...
