The biology fermentation process with controlled multi--variable and non--linearity is a strong--coupling complex control system. Regarding to the analysis of the biology fermentation process, the communication network of the data gathering based on the blue --tooth wireless communication technology is built in this paper. The hardware circuit of the system based on blue--tooth module realizes the wireless communication between the equipments, and designs a monitoring interface for the upper machine by C＋＋. The presented system effectively overcomes the shortcoming of the complex connection of cable conductor in the biology fermentation process, and establishes a set of feasible multi--computer communication solution for acquisiting and controlling data in industrial locale. The experiments show that system is stable and reliable, the parameters meet requirements of the fermentation process to achieve the real--time monitoring.
