Rotary cabinet automatic control switch circuit

Abstract

The present invention belongs to the field of the switch circuit. An automatic control switch circuit of a rotary cabinet comprises a switch circuit, a low-voltage circuit board, a monitoring circuit and a control circuit, wherein the switch circuit, the low-voltage circuit board, the monitoring circuit and the control circuit are electrically connected in turn. The switch circuit includes a programmable time switch and an alternating current contactor, and a high voltage-to-normal voltage power supply in parallel connection with the programmable time switch and the alternating current contactor, wherein the programmable time switch is in series connection with the alternating current contactor; the monitoring circuit includes an operation platform with a touch screen, a circuit board and a computer electrically connected in sequence; and the control circuit includes an RFID reader and an RFID antenna electrically connected in sequence. According to the automatic control switch circuit for the rotary cabinet, the trouble that electrical appliances need to be opened and closed one by one can be solved, hidden dangers caused when an electrical appliance is forgotten to be closed can be avoided, preparation and ending work are carried out automatically, manpower is liberated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of switch circuits, in particular to an automatic control switch circuit for a rotary cabinet Background technique [0002] The rotary cabinet is a new generation of automatic file storage equipment. It consists of two parts: hardware (cabinet, PLC / single-chip microcomputer, embedded system, electric motor, serial port, shielded wire, etc.) and software (computer networking file management system). [0003] The file administrator only needs to enter the name, number or actual information of the person to be searched for and then confirm, and the required files will be automatically transferred to the operation exit for access. The file cabinet has the functions of intelligent access, digital query, inventory report and permission setting. It is widely used in various file management such as cadre personnel, financial integration, etc. It is convenient and quick to access files, make full use of the space in the des...
