After starting coding lock system, the demonstration maintenance menu whether the microprocessor system proceeds to be provided with by display display alarm staff; Described microprocessor system controls described keyboard and is in selection and whether proceeds to be provided with function;
Selecting by described keyboard is when proceeding to be provided with, and the microprocessor system shows the password setting menu that encrypted message is set by display; Described microprocessor system controls described keyboard and is in the password setting function;
After password setting was finished, coding lock system locked, and controlled described anti-combined floodgate module and enter anti-"on" position, and closing operation is blocked; The microprocessor system shows the release menu by display simultaneously, described microprocessor system controls described keyboard and is in unlocking function, finishes release after the password of the above-mentioned setting of input, password inefficacy simultaneously, described anti-combined floodgate module withdraws from anti-"on" position, allows to carry out closing operation.
Password in the above-mentioned design is set up on their own by maintainer or other staff, and password ceases to be in force automatically after each release.Effectively avoid the problem that other staff carry out release in the maintenance, further ensured maintainer's safety.The utility model operating procedure is simple, can effectively save time for the staff.
Store a high grade cryptosystem that sets in advance in the described microprocessor system, under the coding lock system locking state, after importing described high grade cryptosystem by described keyboard, finish release, the password of staff's setting simultaneously lost efficacy, described anti-combined floodgate module withdraws from anti-"on" position, allows to carry out closing operation.
Forget the staff under the situation of set password, perhaps forget release, and during for the release in time of work reason, the related personnel can carry out release by high grade cryptosystem the staff.In order to avoid influence operate as normal.
