Design of Wireless Temperature Measurement System for Chicken Hatch Field Based on LabVIEW

Abstract

Aiming at the influence of temperature on the rate of chicken’s hatchability in hatch field, this paper uses a flexible wireless VISA communication technology based on LabVIEW to measure and control the temperature in process of chicken hatching. The hardware part was composed of microcontroller C8051F530, digital temperature sensor DS18B20, wireless data transmission module nRF and display module HB240128 for real-time acquisition and processing of temperature data. The software part was written by graphical programming software LabVIEW, and used it to design system interface for functions of real-time processing of temperature data, waveform display, threshold alarm etc. The system can be implemented by hardware circuit itself and computer system interface for the temperature control, which enhanced flexibility of the system and was conducive to troubleshoot interference problems. The test results show that the temperature measurement system was characterized by simple operation, easy maintenance, steady performance and high accuracy.
