The development of remote monitoring system for cultivation environment of Pleurotus eryngii

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 etc., this system is 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 eight Pleurotus greenhouse simultaneously, 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. 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. This study provides effective technical support for establishing the growth model of Pleurotus eryngii and forming the control strategy of saving energy, so as to improve the quality and yield of Pleurotus eryngii.
