Abstract

The design is electronical and communication system design of library and laboratory building of Guazhou weak electric engineering is formed by automatic fire alarm system, cable TV system, on the house phone line system, cable radio sound system, high building electronic contact system, security and the monitoring and control system etc.

This design melon state second book building belongs to level 2 protection object, the main content of the design is automatic fire alarm system, cable TV system, telephone system, network system design. Based on the present standards, for automatic fire alarm system, according to each floor different architectural features of the room and use according to the choice of fire detectors requirements needed to determine the type of fire detectors, according to the division of regional detection for the number of detector of calculated, according to standard reasonably determine the detector and manual alarm button, fire control radio, fire hydrant decorate position; To communication systems, according to the rules, the major TV, phone and Internet socket selection and installation method of design. This design uses electrical and AUTOCAD software when it is to draw the fire plane and system graph, weak electric plane and system graph, etc.

The overall design accords with the relevant technical regulation requirements. Equipments selection is reasonable so as to better meet the applicable functions and be able to better guide the construction.
