| Summary: | 碩士 === 國立中興大學 === 生物產業機電工程學系所 === 99 === This study attempts to develop an online system for measuring the weight of live chickens and analyzing the image of combs in order to improve the management of breeding chickens. The system includes a major machine that adopts a belt transport mechanism as the guidance device, uses a belt scale consisting of belts and load cells to measure the weight of a chicken, and does not need the traditional preprocess of folding chicken wings in the measuring procedure. The LabView is used to integrate all kinds of instruments. RFID is first employed to read the serial number of a chicken wing, and then the weight data within the measuring range defined by a photoelectric switch are recorded. In a later stage of the system, a CMOS video camera is used to capture the images of chickens, and the stored images could be captured in an appropriate size to meet subsequent requirements. It is unnecessary for the recorded data to be transcribed manually, as the system features an automated output and is able to be linked to the information management system at a parent-stock native chicken farm. There is an error range of ±5% between the weight measured by this system and that measured manually. The whole process only needs a worker to run to accomplish the weight measurement work, and it takes approximately 25 seconds at a time to complete the operational process of weight measurement and image capture. After including the time spent grabbing a chicken and reading the wing number, approximately 90 chickens can be processed per hour. When the image processed by the system is converted into the area of the comb, the figure is 10%-50% less than the area measured manually.
