The relation between the question

"only one appliance is turned on to off and beside no other appliance is turned on"

and the code is not clear:

%% ******************************************************************************************************
% º¯ÊýÃû³Æ£ºEventLog
% º¯Êý¹¦ÄÜ£º±£´æÊ¶±ðÊÂ¼þ»òÒì³£µ½txtÎÄ±¾EventLog.txtÖÐ
% ÊäÈë²ÎÊý£º sVersion - °æ±¾ÐÅÏ¢
%           sCurrentTime - µ±Ç°²âÊÔÊ±¼ä
%           sTime - ²âÊÔ¼ÇÂ¼ÄÚ±£´æµÄÊ±¼ä
%           sEvent - ·¢ÉúµÄÊÂ¼þ
% Êä³ö²ÎÊý£ºÎÞ
%% ******************************************************************************************************
function [ ] = EventLog(sFielsName, sVersion, sCurrentTime, sTime, sEvent)
fid = fopen(sFielsName,'a+');
fprintf(fid,'| %s |\t ',sVersion); 
fprintf(fid,'| %s |\t ',sCurrentTime); 
fprintf(fid,'| %s |\t ',sTime); 
fprintf(fid,'| %s \r\n', sEvent);  % »»ÐÐ
fclose(fid);

I do not think, that the term "appliance" help to understand, which problem you have.

By the way, you can simplify the code to:

...
fprintf(fid,'| %s |\t ',sVersion, sCurrentTime, sTime); 
fprintf(fid,'| %s \r\n', sEvent);  % »»ÐÐ
...

The question is ;

The algorithm recognizes the opening of a single appliance and counts the number of data from opening to closing of a single appliance

Is to see how many lines the data reads when only one appliance is turned on to off and no other appliance is turned on ..
