摘要
为了实现4台风机的远程、智能、高可靠性控制,同时需要满足调试方便、每台风机能够正转、反转的功能。提出了一种采用本地控制系统与远程终端指令控制相结合的控制方法,设计了一台本地控制系统。本地控制系统有3种工作模式,分别为手动控制模式、自动控制模式、遥控控制模式,可以通过模式开关进行工作模式切换,同时也能够根据预设的控制逻辑进行自动控制模式与遥控控制模式之间的自动转换。手动控制模式下可以根据面板的风机控制开关控制每台风机的正转、反转及停止;自动控制模式可以根据环境温度自动控制每台风机的正转及停止;遥控控制模式下可以根据远程终端的命令控制每台风机的正转、反转及停止。本地控制系统开机后还能够按照50 ms的周期进行采集环境温度及风机的运行状态等信息,并把这些信息外发给远程终端。远程终端选用带有网口的通用计算机或智能终端即可,采用该方法研制了一套样机,该样机已无故障运行17个月,3种工作模式都能正常工作。
In order to realize the remote,intelligent and high reliability control of the four fans,it is necessary to meet the functions of convenient debugging and forward rotation and reverse rotation of each fan.A control method combining local control system with remote terminal command control was presented,and a local control system was designed.The local control system has three working modes,namely manual control mode,automatic control mode and remote control mode.The mode can be switched by mode switch,and the automatic conversion between automatic control mode and remote control mode can also be carried out according to the preset control logic.In manual control mode,forward rotation,reverse rotation and stop of each fan can be controlled according to the fan control switch on the panel.Automatic control mode can automatically control the forward rotation and stop of each fan according to the ambient temperature.In remote control mode,the forward,reverse and stop of each fan can be controlled according to the command of the remote terminal.After the local control system is started,it can collect the ambient temperature and fan running status every 50ms and send the information to the remote terminal.The remote terminal can be a general computer or an intelligent terminal with a network port.A prototype was developed by using the method.The prototype has been running without failure for 17 months,and all three working modes can work normally.
