摘要
Abstract
The traditional central air conditioning system transfers data by RS485 and causes some problems such as increase of interference,bad adaptive control and short communication distance,a new type of central air conditioning control system is designed,the system’s new thermostat transmits data via Modbus/TCP. Modbus/TCP gateway is designed by this way, the old temperature controller based on RS485 bus characteristics and Modbus/RTU transmission will be able to connected to the new conrtol system. Besides, the new thermostat and Modbus/TCP gateway is based on μC/OS-Ⅲand LwIP . This system makes full use of the existing temperature control device and bus resources,and it solves the limit of the number of devices,system response delay,short communication distance and low speed problem. After a long time test,new thermostat and Modbus/TCP gateway servers meet in communica-tions,the working state of the gateway is stable and reliable.关键词
