Industrial counter with power-off protection and counting method

Abstract

The invention involves a kind of power protection industry counter and the counting methods, including microcontroller, counting signal acquisition and conditioning circuit, power protection circuits, timing clock, and relay driver output circuit, LCD modules and restart and reset circuit; the relay driver output circuit is used for driving relay; the timing clock is used for power off interruption and saving the interruption data; the counting signal acquisition and conditioning circuit is used to the trigger of external interrupt of chip; the interrupt signal through the non-door, resistance R1, triode and external interrupt of chip, the output voltage pulse from the sensor through signal conditioning circuit to implement the jump of high and low level voltage of external interrupt INT0; external interrupt mode is set to falling edge triggering, when the external interrupt is triggered, enter the interrupt service procedures and process count. The beneficial effect of this invention is: a relay output function, easy and convenient operation, safe and reliable, low cost, and a wide application range.

Description

Technical field [0001] The invention relates to the field of counters, mainly an industrial counter with power-off protection and a counting method. Background technique [0002] The counter is one of the commonly used control devices in industrial production and scientific experiments. It is widely used to count the number of various parts and components, the count of repetitive experiments, and the statistics of the number of changes in various signals, etc., where pulses are counted. It can be applied, such as counting steel strips in rolling mills, counting printed publications in printing plants, and various industrial production fields that require repeated counting. Counters play an important role in improving productivity, saving labor and production costs. [0003] At present, most of the counters on the market use single-row digital tubes as display devices. The display digits are 4 or 6 digits. Many of them cannot display the pre-designed value and the real-time count ...

AI Technical Summary

Problems solved by technology

This counter also has some problems to be further solved, the stability and reliability need to be further improved, the size and appearance of the product are not small enough and beautiful, and there are still deficiencies in the convenience and flexibility of the user's use.

Industrial production sites will inevitably encounter sudden power failures. When the system unexpectedly loses power, important data will be lost and cannot be recovered.
