Design of Safety Network and Power Distribution of Underground Shops of Suqian Powerlong City Plaza

摘要

This paper focuses on two main aspects including building safety and energy saving of power distribution system. First of all, BACnet protocol based network characteristics of safety system of underground shops of the Suqian powerlong City Plaza is introduced. And then the fieldbus control network which centers around world well-known PLC such as AB ControlLogix, Siemens S7-300 and Siemens S7-400 is mainly adopted in the design of fire linkage system. ControNet network connects to PROFIBUS network by PD-100S protocol convertor which can convert one protocol to another between DeviceNet and PROFIBUS-DP network. In the design of power supply network, power loss calculation of dry-type transformer is considered firstly, and then empirical design mistaken cognition of power supply network is analyzed and solution for improvement is presented.
