Abstract: This paper focuses on the questions of air-handling-unit like half-baked monitors, low-degree automa-
tion. data-share difficulty, low-rate insulation of fault and so on. The system based on B/S model is set up by appl
ing technologies of virtual instrument, multi-threading and network-communication. Its network frame is built, and
relative software and hardware are developed completely. Clients can use WEB to browse the run states of the com-
binational air-handling-unit's instruments, demand history information, and know about the fault information, and
make a decision by this system. For the moment, this system is running safely and stably all the way on locale. Its
excellences include high human-machine alternation, convenient update and so on. This system has applied worth
and realistic meaning to carrying out a network to monitor air-handling-unit
Key words: air-handling-unit, network; state monitor systerru
