Abstract: Embodiments of the present disclosure disclose an authorization method and an apparatus applied to an electronic lock. The method performed at a server hosting an instant messaging application includes: receiving an authorization request sent by a first instant messaging client at a first terminal, and the authorization request being used for requesting to grant use permission on the electronic lock to a second account; querying for, according to the authorization request, key information bound to the second account; and sending the key information to the electronic lock, the electronic lock being configured to add the key information into a trusted key information store. Moreover, the instant messaging application at the server can also be involved to further enhancing the authenticity of a person who tries to unlock the electronic lock based on the location of a terminal used by the person for accessing the instant messaging application.

Abstract: A dual-sensor signal collecting circuit comprises circuit (11), a second sensor signal collecting circuits, an AD sampling circuit, an AND gate determination circuit and a collected signal averaging circuit. Output ends of the sensor signal collecting circuits are connected to respective input ends of the AND gate determination circuit, respective input ends of the collected signal averaging circuit and a first AD sampling port of the AD sampling circuit; an output end of the AND gate determination circuit is connected to a power supply end of the collected signal averaging circuit; an output end of the collected signal averaging circuit is connected to the first AD sampling port of the AD sampling circuit. When the sensors operate normally, the collected signal averaging circuit outputs an average sampling value to the first AD sampling port, when one is damaged, a sampling value of the one operating normally is output to the first AD sampling port.
