Design of train air-conditioning control system
Abstract With the development of society, people's living standard has been greatly improved and the requirements on the transportation comfort is becoming higher and higher。All of this promote the application of train air conditioning technology in the railway transport system。The control of train air conditioning system has became an important research direction。The main research contents of this paper are:The composition, internal structure, working principle of the train air conditioning system and how can we combine the train set air conditioning system with PLC and frequency converter。
The system is designed to collect and detect the humidity and temperature in the train。In the air conditioning system, the speed of the train air conditioning motor can be changed by adopting the technology of frequency conversion。It also can adjust the temperature, so that we can make sure that the system is in the best running state achieve the aim of saving energy。In the train air conditioning control system,converter and PLC make the train air conditioning operating system become simple, functional and reliable 。
There are 16 figures, 4 tables and 28 references in this paper。
Key words: air-conditioning system PLC control system frequency conversion technology
