Abstract

The invention relates to an automatic control system and an automatic control method of a multimedia device. The automatic control method comprises the steps of first electrifying a coded lock, and inputting a user name of a school teacher; verifying whether the inputted user name exists or not, and transmitting a dynamic password to a handheld device which is bond with the user name after the inputted user name conforms to the user name of the teacher real in class; inputting the dynamic password in an input password area, opening the coded lock of the multimedia device after a processor verifies that the dynamic password is correct, and starting the multimedia device to work. By respectively comparing the user name information and the dynamic password information with the stored information, the multimedia device can only be opened after the user name information and the dynamic password information pass the verification, so that the safety of the multimedia device is guaranteed by adopting the way of automatically opening the coded lock, the work load of the key management personnel can be alleviated, the waste of time for the teacher to travel between a classroom and an office room can be avoided, and the real-time class information of the teacher can be accurately controlled.

Description

technical field [0001] The invention relates to an automatic control system and method for multimedia equipment. Background technique [0002] Locks are ubiquitous tools used to prevent theft in daily life. They can be seen in logistics transportation, warehousing, cash transport vehicles and other transportation fields, as well as in all aspects of life such as car locks, electric car locks, and storage cabinets in supermarkets. Wide application of electronic combination locks. At present, multimedia equipment is commonly used in colleges and universities. However, every teacher has to go to the duty room to get the key of the multimedia equipment and sign in before class.
