摘要
针对目前养鸡场存在的鸡舍内环境复杂,监测参数众多,实时监测性差和控制设备自动化程度低等实际问题,设计了一种基于可编程逻辑控制器的多参数监测控制系统,对规模化养鸡场环境实时监控。传感器将采集到的信息经过RS485总线传输到PLC,经处理后传送至上位机,上位机对PLC传送来的数据与设定值进行比较,将相应的控制指令发送到PLC,控制通风系统等相关控制设备的启动和停止。实验结果表明,该系统运行稳定,响应迅速,能很好的实现对温度、湿度和氨气浓度的检测并且通关相关设备将这些参数控制在合适的范围内,能够保障肉鸡的健康成长,具有一定的市场应用推广价值。
In view of the current problems in the scale of chicken farms, such as the complex environment, the large number of monitoring parameters, the poor real-time monitoring capability and the low degree of automation of control equipment, A multi-parameter monitoring and control system based on programmable logic controller （PLC） was designed to monitor the environment of the scale chicken farms in real time. The sensor transmitted the collected information to the PLC via the RS485 bus, After treatment and sent to the host computer, The host computer carried on the analysis, the processing, the storage to the data which transmitted, and carried on the comparison with the hypothesis value, The corresponding control instruction was sent to the PLC, Control the ventilation system and other related control equipment start and stop. Experimental results show that, The system operates stably, Rapid response, The temperature, humidity and ammonia concentration can be well detected and the related equipment can control these parameters in the appropriate range, To ensure the healthy growth of broilers, with a certain value of market promotion.
