摘要
在禽蛋孵化过程中的胚胎监控对家禽行业的发展具有非常重要的意义。该文设计了一套能获取孵化期活体禽蛋胚胎胎动信号的监测系统,提出一种半侵入法测量禽蛋胚胎胎动的新方法。先在禽蛋气室的顶部用针扎一个小洞,使活体胚胎的胎动信号经气室放大后传出来,然后带动贴在小孔上的铝箔运动,再通过位移传感器对其进行测量。本系统在不影响胚胎发育情况下,能对禽蛋胚胎进行识别,具有操作简单、可靠性高等特点,为进一步研发禽蛋发育过程的自动监控系统奠定了基础。
The monitoring of embryo in the period of egg＇s incubation is very important for the development of poultryindustries. A monitoring system was devised,which can extract the heartbeat signals of the chick embryos in the period of incubation. A novel semi-invasive method was developed to measure these signals. With this method,it is needed to make a small hole on the top of the egg＇s air chamber by a pin in order to amplify the heartbeat signals through the egg＇s air chamber. And then a piece of thin tinfoil is pasted on the small hole,and the transducer of displacement is employed to measure the vibration of thin tinfoil. So the embryo can be inspected whether alive or not by the signals. Taking advantages of high reliability and simple operation,the system can be used to identify the live bird embryos without affecting the development of embryos. This research can provide a foundation for further exploring the automatic monitoring of the process of embryonic development.
