Abstract

The invention relates to the field of radio frequency identification, and in particular relates to an attendance machine powered by the Ethernet. The attendance machine powered by the Ethernet mainly comprises peripheral equipment, a main control singlechip and a radio frequency identification base station, wherein the peripheral equipment is connected with an input end of the main control singlechip, and an output end of the main control singlechip is connected with the radio frequency identification base station, therefore, the attendance machine can be powered by virtue of Ethernet connection and does not need to use an AC (alternating current) power socket on a wall, so that wiring is greatly simplified, and the construction cost of network infrastructures is reduced; and moreover, by virtue of power supply with a UPS (uninterruptible power supply) backed-up local area network, network equipment can be prevented from influence caused by power failure of a power grid and can still run normally during power failure as a telephone system, and a power receiving module is additionally arranged in the attendance machine to receive a power supply on an Ethernet signal line and convert the power supply to have a voltage required by the attendance machine.

Description

technical field [0001] The invention relates to the field of radio frequency identification, in particular to an attendance machine powered by Ethernet. Background technique [0002] Existing attendance machines with Ethernet functions have used a separate power input port to input power. The time attendance machine is equipped with a power adapter when it leaves the factory, and an AC socket needs to be installed near the installation location during installation. time does not work properly. Contents of the invention [0003] The purpose of the present invention is to provide a power-over-Ethernet time attendance machine, aiming at solving the problems that the time attendance machine cannot continue to try out when the power is cut off. [0004] The present invention is achieved in this way, a power-over-Ethernet attendance machine, the power-over-Ethernet attendance machine is mainly composed of external equipment, a main control single-chip microcomputer, and a radio...
