Title Design of remote online monitoring system of water Chiller
Abstract
Since the reform and opening up, China's social development level and people's living standards greatly improved. Hvac systems are becoming more and more important in people's production and living.While the chiller is the key of the hvac equipment.When chiller failures, equipment performance decrease, energy consumption increase, meantime it reduces the level of user’s comfort. Today,in the pursuit of quality of life and energy savings , it is necessary for real-time monitoring of chillers,It can prevent the occurrence of the fault in time, and make it back to normal with the fastest speed after a fault .Remote testing system based on GPRS can easily realizes the monitoring of the state signal of water chiller.First of all, according to the current development level of monitoring, the overall design scheme is given in this paper,Secondly it analyzes the architecture of the chiller and the characteristics of acquisition parameters,Then it introduces the signal acquisition module ADAM4117,ADAM4015 and F2114 GPRS IP MODEM and the upper configuration software ForceControlV7.0.Finally,studies the specific implementation process of GPRS-based remote online monitoring of chillers.
