Temperature control system based on peripheral component interconnection (PCI) protocol

Abstract

The invention discloses a temperature control system based on a peripheral component interconnection (PCI) protocol. The temperature control system based on the PCI protocol comprises a PCI bridge module, a photoelectric coupling module, a temperature detection module and a resistance heating module, wherein one end of the PCI bridge module is directly connected with a personal computer (PC) through the PCI protocol, and the other end of the PCI bridge module is connected with the photoelectric coupling module through a signal line; the temperature detection module is connected with the photoelectric coupling module through a signal line; and the resistance heating module is controlled by the photoelectric coupling module. According to the temperature control system based on the PCI protocol, the PC can be directly used for collecting the temperature of a heating device, the heat quantity of a resistance wire can be controlled directly by the PC, meanwhile, isolation between strong current and weak current is realized, and the PC is protected.
