稻田自动化鸭舍声训系统设计与试验研究

为使稻田自动化鸭舍在无人值守的情况下于日落之前自动唤鸭回舍,降低人工消耗,设计了稻田自动化鸭舍的声训系统。该系统可产生并自动播放不同类型、声压级及频率的纯音信号。以1月龄鸭子为研究对象,以声音的声压级和频率为试验因素,以鸭子回舍时间为试验指标,对声训系统进行了试验研究。结果表明:鸭子回舍时间与声音参数存在线性回归关系;当声压级为85d B、声音频率为18 577Hz时,鸭子回舍时间最快可达到19.52s,满足稻鸭共作生产的要求。研究结果为稻鸭共作技术条件下的自动化鸭舍设计提供了依据。

Design of Voice Training System for Automatic Duck Shed in Paddy Field

A vocal duck training and gathering system automatic duck shed in paddy field was designed to summon ducks back the shed before sunset without manual intervene to reduced labor consumption .The system can generate and broad-cast kinds of pure tone which sound pressure level and frequency can be modified .Experimental study on the vocal duck training and gathering system was carried out to ducks of one month age , with sound pressure level and frequency as ex-perimental factors , and the time of ducks returning shed as experimental index .The results showed that the time of duck returning shed was in linear regression relationship with sound parameters .The time of ducks returning shed was 19 .52 s at sound pressure level of 85dB and frequency of 18 577Hz.It indicates that the system can meet the requirements of rice-duck eco-farming .The research results may provide references for the design of automatic duck shed .
