Abstract

The invention discloses a computer security system, comprising an AT89S52 single-chip microcomputer, a temperature sensor DS18B20, a key, indicator lights and a buzzer. When in use, the computer security system disclosed by the invention is installed in a mainframe box of a computer, wherein the key and the indicator light are arranged on a shell of a computer mainframe; temperature information in the mainframe is collected by the temperature sensor DS18B20; a temperature signal monitored by the temperature sensor DS18B20 is read by a P2.4 port of the AT89S52 single-chip microcomputer in real time, and the temperature signal is compared with set limit alarm temperature; when the temperature signal exceeds the alarm temperature, a signal is sent to the buzzer by a P2.3 port of the AT89S52 single-chip microcomputer to control the buzzer to perform alarm output, and meanwhile, a red indicator light is controlled to be turned on through a P2.1 port.

Description

technical field [0001] The invention belongs to the technical field of computer security, and in particular relates to a computer security system. Background technique [0002] In a large-scale industrial computer room, the cooling conditions and temperature conditions of the computer have a great influence on the working efficiency and service life of the computer; the temperature system of the common computer today only collects the temperature, and does not provide high temperature alarm protection. If the temperature of the computer is too high, without alarm protection, it will cause great damage to the computer components, and at the same time, it will also have a great impact on the normal operation of the computer, so it is urgent to have an over-temperature alarm protection suitable for computers. device to realize high temperature alarm protection for the computer. Contents of the invention [0003] The purpose of the present invention is to overcome the deficie...
