BVSV is applied in the hydraulic network of the heating and cooling system to realize holographic data collection and hydraulic control of the network; it solves the problem of systematization of data collection of the network system and synchronization of hydraulic balance control. All data can be displayed locally through mobile terminals or presented on cloud platforms through RS-485 and MODBUS-RTU transmission, which can provide hardware support for digital management and control of the network.
