AI Technical Summary

Technical Problem

The current technology does not have an appropriate testing frequency for RAM modules, which cannot effectively guarantee the normal status of the air conditioner RAM modules after they are sold, thus posing a safety hazard.

Method used

The RAM module is divided into a buffer area, a general area, and a stack area. Based on the microcontroller's operating speed and the program runtime threshold, it is further subdivided into multiple sub-areas. These are then detected sequentially during the program's execution intervals, generating abnormal alarm information and stopping the detection.

Benefits of technology

It enables segmented, time-division, and cyclical continuous detection of RAM modules, increasing the detection frequency, ensuring device safety, and without increasing additional device hardware circuitry and configuration costs.

Abstract

The application belongs to the technical field of household appliance control, and particularly relates to a RAM module detection method based on a single-chip microcomputer, equipment and a storage medium. The method comprises the following steps: obtaining a detection running duration according to the running rate of the single-chip microcomputer and a program running duration threshold; dividing the buffer area, the general area and the stack area into a plurality of buffer sub-areas, a plurality of general sub-areas and a plurality of stack sub-areas respectively according to the detection running duration; detecting each sub-area in each area in turn, and generating and playing alarm information and stopping the detection when an abnormal result is detected. The method of the application utilizes the equipment program running gap, does not additionally increase the power-on running duration of the equipment, realizes the segmented, time-sharing and cyclic uninterrupted detection of the RAM, the detection process accompanies the entire life cycle of the equipment, is more reliable, does not increase the additional equipment hardware circuit, and thus does not increase the equipment configuration cost.
