FFU touch screen control oled module

1) the central control unit, PLC controller. To achieve the following control functions:
◆ intelligent control module with field bus system using RS485 connection method, the collected field data analysis, processing; achieve on-site equipment control functions. In order to achieve all of the on-site centralized monitoring and control of FFU. 16x2 oled display
◆ communicate with the alarm control unit.
◆ with the man-machine interface unit to communicate.
2) human-machine interface unit, using the touch screen to achieve remote monitoring and adjustment for FFU. To achieve the following control functions:
◆ be able to facilitate the realization of FFU single, multiple, and zone control. That is, an arbitrary number of units can simultaneously control the FFU.
◆ FFU can achieve any number of units start and stop and speed control function, speed control function enables digital, that is, directly enter the desired velocity value (example: 0.25,0.31, etc.) in order to achieve the purpose of speed.
◆ Renyiyitai FFU capable of monitoring wind speed values.
◆ When a fault alarm FFU, can display real-time fault FFU.
3) alarm control unit, using sound and light alarm devices, through communication with the central processing unit, when any one or more FFU fails, the control unit real audible alarm, and with the man-machine interface unit with quickly determine the fault FFU, monitoring personnel to ensure timely processing failure. 5.7 TFT display module
