Abstract
The invention relates to a dissolved oxygen control device. The device comprises a host computer, a blower controller, a valve distribution controller and a TCP/IP communication network. The upper computer and a blower are connected in a TCP/IP mode and are used for displaying the operating state of the blower controller and transmitting control parameters of the blower controller to lower levels. The blower controller is used for controlling the overall air supply of the blower. The host computer and the valve distribution controller are connected in a TCP/IP mode and are used for displaying operating parameters of the valve distribution controller and transmitting the control parameters of the valve distribution controller to lower levels. The valve distribution controller is used for real-time adjustment of the valve opening degree. The invention also relates to a dissolved oxygen control system. Through cooperation of the host computer, the blower controller and the valve distribution controller, low power consumption and high precision dissolved oxygen control can be realized under the condition of multi-channel simultaneous aeration and the whole control system has a stable output control effect.
