With the development of agricultural modernization,the edible fungi industry has gradually changed from artificial cultivation to factory production,which has improved the quality of mushroom production,cost and cultivation efficiency.At present,the development of industrial production of edible fungi is focused on bagging,packaging and other links.For the lack of thorough and comprehensive research on the environmental regulation techniques,there are problems such as inaccurate daily monitoring and low level of system control,this has become one of the important factors that restrict the further industrialization and automation of edible fungi production.Therefore,in view of the imperfect and immature environmental monitoring technology in the cultivation stage of edible fungi,relying on the production base of Pleurotus Eryngii in the minning science and technology demonstration park of Ningxia Pengyang County,based on the analysis of the growth characteristics of PLEUROTUS ERYNGII in the growing stage,a monitoring system based on Internet of things was designed.In view of the problem of large quantity,wide distribution and difficult data collection in the mushroom greenhouse,and considering the present situation of hard wiring in the cultivation base,a sensor network of the system based on Zigbee wireless transmission technology is proposed,it solves the problems of high wiring cost and difficult maintenance in the later period of the traditional wired monitoring system.In order to solve the problem that the environment of mushroom greenhouse can not be monitored remotely,the cloud platform technology is introduced into the monitoring of edible fungi production.In order to solve the problem of complex interaction of environmental factors and the difficulty of effective control by traditional control methods,the mathematical model of mushroom-producing greenhouse was established,and the control method based on PID control and mould and control was proposed,the simulation results of traditional PID controller and the mold and the theory of fused-mold and the mold and the PID controller in Matlab environment show that the mold and the mold and the PID controller can adjust the environment of mushroom-producing greenhouse more quickly.Finally,based on the single-room model of mushroom-producing greenhouse equipped with spray and ventilation equipment,the system monitoring function experiment was carried out in the laboratory environment to verify the accuracy of the monitoring data of the system.At the same time,the environmental regulation experiment of single-room model of mushroom-producing greenhouse is completed,which proves that the mold and PID controller has better regulation performance,anti-interference ability and response time than PID controller.The test of the system wireless transmission ability is completed,and the communication ability of the system is verified to meet the transmission requirement.The field experiment in Pleurotus Eryngii planting base shows that the system can run stably all the time,and can provide a stable environment for mushroom production.
