3) judge inspection shaft environmental information and well lid state, if normally then data are stored on the server at data base management system (DBMS) place; If undesiredly then change next step over to;
4) judged whether that alert event occurs, if do not have alert event to occur then this event is recorded preservation; If have alert event to occur then change next step over to;
5) judge whether type of alarm is the well lid abnormal start-up, if not abnormal start-up, this event is recorded preservation and notifies the related personnel to keep in repair; If be abnormal start-up then send alerting signal, the Long-distance Control manhole lid device, the relevant responsible person of notice also stores alert event and process information on the server at data base management system (DBMS) place into, for the history report inquiry, print.
