Research Of Soy Sauce Koji-making Intelligent Monitoring System Based On Internet Of Things

Koji-making that is a key directly affects the quality and yield of soy sauce. With the development of modern science and technology, soy sauce Koji has gradually from traditional manual Starter to automation, mechanization. Due to the mechanical upgrade costs too high, the thick layer ventilation system, which is low cost, extensive management, regulatory lag, will be still mainly used in our country. It carefully analyses the thick layer ventilation system in this paper, and designs a kind of soy sauce Koji-making intelligent monitoring system based on IOT, which can implements real-time monitoring to the various influence factors and accurate controlling to temperature of raw material in the process. This paper main work is as follows:(1)Detailed analysis Koji-making of soy saucy and thick layer ventilation system. Study on the best monitoring and control method of parameters in Koji-making process. Discuss the overall design scheme of the system.(2)According to the hardware design, founded the monitoring network system which based on WSN, describe the network topology and its software realization processes, select appropriate sensors, complete hardware system design of sensor nodes.(3)According to the hardware design, founded the controlling network system which based on WSN, describe the network topology and its software realization processes, discuss the control object and its control method, perform hardware system design of sensor nodes.(3)Design the gateway of system and describe its functions and tasks, Perform the gateway hardware circuit design and software implementation of PID control algorithm.The test results show that the performance of sensors and control network at the bottom of system is reliable, and it can guarantee flow and stability for the wireless data link. The low power sensor nodes after a charge can work persistently at several Koji-making cycles. Modulating the power of ventilators, PID can accurately control the temperature of the Koji-making materials. Overall, the function of the system reaches the expected design effect, and it has a certain practical and promotional value.
