Wireless measurement and control system for grain condition based on multiple networks

Abstract

The invention discloses a wireless measurement and control system for a grain condition based on multiple networks. The system comprises wireless sensor nodes, a detecting and controlling sub-machine, a coordinator, a monitoring PC machine, a printer, a monitoring mobile phone and a remote PC machine, wherein the detecting and controlling sub-machine comprises a CC2530 core board, a WCDMA network module (MC8781) and a power supply; and each wireless sensor node comprises a CC2530 core board, two temperature cable groups, a temperature and humidity sensor (SHT15) and a power supply. Acquired grain condition data is transmitted to the detecting and controlling sub-machine on the outer wall of a granary via a ZigBee network by the wireless sensor nodes in the granary; the detecting and controlling sub-machine reports the data to a WCDMA network base station via the WCDMA network module (MC8781); the WCDMA network base station directly communicates with the monitoring mobile phone or reports the data to the remote control PC machine via the Internet; simultaneously, the detecting and controlling sub-machine transmits the grain condition data to the coordinator via the ZigBee network; and the coordinator transmits the data to the monitoring host via RS232 serial ports. The wireless measurement and control system provided by the invention has the characteristics of multi-network communication, reasonable nodes distribution, low system power consumption, low cost and fast data transmission rate.
