R & D Of Remote Monitoring Platform For Pleurotus Cultivation Environment Factors

In recent years, the northern region of China has become an important base for the production of edible fungus due to the low temperature of natural conditions and abundant labor force in the rural areas and the cultivation of raw materials with cheap hyphae. The rare edible fungus Pleurotus eryngii attracting a large number of growers with its rich nutritional value. On the current development trend, factory and the anniversary of the cultivated Pleurotus eryngii will also be the inevitable trend of industrial development. Complex biological characteristics determined the Pleurotus eryngii is particularly sensitive to its cultivation environment. In particular, environmental factors such as temperature, humidity, carbon dioxide concentration and light intensity both have regulation function on its growth and development, morphogenesis, gene expression and metabolism, etc. However, the current regulatory technology of environment for the cultivation is not yet mature; this is one of the important factors restricting the Pleurotus eryngii factory cultivation.Aiming at the defects of the existing technology for Pleurotus eryngii cultivation environment monitoring system in Ningxia Pengyang County. Such as:transmission of the data is not stable, small monitoring range and the sensors cannot move conveniently. Only the environmental data in a fixed position within each mushroom shed can be collected. Need to lay a lot of cables between the collector and the sensors, wiring difficulty, high cost and so on. This system is based on single-chip, the integrated application of multi sensor fusion technology, Bluetooth wireless transmission technology, GPRS wireless remote transmission technology, combined with the wireless RF module NRF905 set up a tree network structure, the PC monitor centre was developed based on the software LabVIEW. Designed a low-cost remote monitoring of digital information platform to automatically, accurately, and remote wirelessly monitor the environmental temperature, humidity, light intensity and carbon dioxide concentration in ten Pleurotus greenhouse simultaneously. And the environmental control equipment heater, refrigerator, fan and shower facilities in each Pleurotus shed can be manually and automatically controlled remotely. The real-time environmental data can also be stored and managed as EXCEL files. Currently, the system has been carried out to promote small-scale applications in comprehensive science and technology demonstration base of edibble fungus in Pengyang County, Ningxia.
