Abstract

A device and process which will monitor the computer's shell and electric source, and it relates to the expansion of SMBus and the use of SMBus slug. The device can be set in the electric source unit and / or on the expansion board. Then it will use the monitor circuit to measure the voltage, the temperature and the speed of rotation of the fan in the shell and the device in the power. After that, it will input the temperature value as feedback signal into SMBus slug. The slug will output the calculated value and after the value is enlarged, it can control the speed of rotation to become a closed loop. The SMBus, the PCI Express board, The PCI board and the PCI-X board are linked to the SMBus interface on the king plank. The positive effect is that intelligent shell and power can be made up to make the computer have no noise to save energy. Besides, through the communication of SMBus and the host computer, the application program can monitor the running state in real time, so it does good to administrating the computer's system device.

Description

technical field

[0001] The invention relates to computer system management bus (SMBus) expansion and the application of components thereof, including a device and a program for monitoring a computer case and a power supply by using a system management bus chip to form a circuit. Background technique

[0002] Computer case and power supply Computer case is an important accessory of the computer. The common forms are ATX and BTX, while the computer server case is larger, and all of them are equipped with motherboard, CPU, memory, display card, hard disk, optical drive and other equipment, or extended SCSI , I / O acquisition board, etc. Due to the high heat generation of the computer, the chassis is usually ventilated and cooled by a fan. One of the devices in the chassis is the computer power supply, which inputs 220V / 110V AC power supply, and outputs energy to the computer after rectification and filtering, PWM control, voltage stabilization and protection circuits, etc. Ther...
