摘　　要：为提高农业育种效率,提出了一种新型农业育种高精度恒温恒湿系统设计方案。基于ARM微处理器LPC2124和嵌入式软件开发技术设计了系统软硬件,采用新型温湿度传感器SHT11实现了育种箱内环境温度和湿度的监测,采用双向可控硅及固体继电器实现了加热和超声雾化加湿电路的工作控制。测试结果表明,系统的测控精度高、功耗低,显著提高了育种效率,具有较高的实用价值和应用推广价值。In order to improve the efficiency of agricultural breeding, a novel constant temperature and humidity system with high precision was designed. The hardware and software subsystems were designed based on ARM microprocessor LPC2124 and embedded software development technology. Monitoring of environmental temperature and humidity inside the breeding box was realized by new temperature and humidity sensor SHTll; and controlling of heating and ultrasonic atomization and hu- midification circuits was realized by bi-directional controllable silicon and solid electric relay. Test results showed that the system was with high measurement precision and low power consumption, which significantly improved the breeding efficien- cy, thus had high practical value and popularization value.
