The granary temperature and humidity detection system, it is used AT89C51 as the main control core, and used the RS232 bus communication to realize the granary temperature and humidity control. The host microcontroller is depended on the AT89C51 to drive, and to display temperature, humidity and brightness, at the same time through the keyboard to enter the master information. The attached master machine used STC12C2052AD as the control unit, the Digital Temperature and humidity data acquisition used sensor SHT11, in each of the master machine and attached machine use of serial communication. When the temperature and humidity exceed the set values, it will alarm.

In this paper, we mainly introduce the serial communication between PC and FPGA and adopt the design principles of DDS phase accumulator to achieve small error of baud rate generator and provide the reliable data transmission. On PC, we use the Labview software to design control interface, which is responsible for sending the control command. The experimental results indicate that the communication is feasible, high stability. This design is applied to the control unit of waveform generator based on FPGA by inputting relevant data on PC such as waveform selection, frequency control, range control and phase control to realize the function of waveform selection, amplitude modulation, phase modulation and frequency modulation.
