Book management system for library

Abstract

The invention discloses a book management system for a library, which comprises a monitoring device arranged on a bookshelf in the library, electronic tags attached to each book on the bookshelf and alibrary server, wherein the monitoring device is internally provided with a microprocessor, a radio frequency signal receiving circuit, an A / D conversion circuit, a wireless transmission module, a touch screen and a power supply circuit, the radio frequency signal receiving circuit receives radio frequency signals sent by each electronic tag and transmits the radio frequency signals to the A / D conversion circuit which converts the radio frequency signals into digital signals, and the A / D conversion circuit transmits the digital signals to the microprocessor; the power supply circuit comprisesa DC power supply, a voltage input end, a voltage output end, a first triode, a second triode, a third triode, a fourth triode, a first resistor, a second resistor, a first voltage stabilizing diode,a second voltage stabilizing diode, a third diode and a first capacitor. The book management system is simple in circuit structure, low in cost and high in circuit safety and reliability.

Description

technical field [0001] The invention relates to the field of book management, in particular to a book management system of a library. Background technique [0002] The library management system is a system composed of people, computers, etc. that can collect, transmit, process, save, maintain and use management information. Use information to control the behavior of enterprises; to help enterprises achieve their planning goals, a system that is widely used in modern large and medium-sized enterprises. The library's book management system comprehensively uses the knowledge of management science, system science, operations research, statistics and computer science. The cost of the existing book management system is relatively high, the structure of the circuit part involved in the book management system is relatively complicated, and the hardware cost is relatively high. Moreover, the circuit part of the existing library management system lacks a corresponding circuit protec...
