Abstract

The invention discloses an access control equipment of access control system, the access control equipment includes: a first detecting unit, used for detecting whether the voltage of a main power supply is below a predetermined voltage value, if yes, the first detecting unit sending a preparation instruction to a power switching unit, otherwise sending a recovery instruction to the power switching unit; a second detecting unit, used for sending a switching instruction if the duration reaches predetermined time in the condition that the voltage of the main power supply is below the predetermined voltage value; the power switching unit, used to disconnect a power supply path between the main power supply and a standby power supply based on the preparation instruction, disconnect a power supply path between the main power supply and an access control host and switch on a power supply path between the standby power supply and the access control host according to the switching instruction, and switch on the power supply path between the main power supply and the access control host and switch on the power supply path between the main power supply and the standby power supply and disconnect the power supply path between the standby power supply and the access control host according to the recovery instruction. The disclosure can provide uninterrupted power supply for the access control equipment.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an access control device of an access control system. Background technique [0002] The access control system is an important part of the community's intelligent system, and it is playing an increasingly widespread role in the field of community security. Since the access control system is usually powered by the mains, there is a situation where the power failure fails. The access control system will control the unlocking of the unit door. If the power failure fails, the unit door will not be able to open normally. [0003] In order to solve this problem, prior art has provided backup power supply for access control system. However, the backup power supply is usually put into use after a power outage in the community, and it is impossible to achieve seamless switching of the backup power supply and uninterrupted power supply for the access control system.
