The operation stability of the traditional building electrical automation system is poor. Therefore, the integrated control network analysis of the intelligent building electrical automation system is proposed. The distributed topology structure composed of the communication layer, the core control layer and the user interface layer is designed. The virtual interface and the USB interface are used to realize the data transmission of the control network. The entire control network adopts the SSDF-S5DA model integrated control chip to send integrated control instructions to the system, so that the system can integrate control. The experimental results show that the designed control network is less than the traditional control network, which is more suitable for the integrated control of the electrical automation system of intelligent buildings.
