CHEN Lin-feng1, SHEN Ming-Xia1, LU Ming-zhou1, et al. Design of wireless sensor networks node for group housed sows drinking behavior monitoring[J]. 2013, 32(1): 118-120+124.
A wireless sensor networks(WSNs) node composed of STM32 microcontroller
CC1101 radio frequency modules and RFID reader/writer module is developed for individual drinking behavior monitoring in group housed sows.Using RFID technology to identify the drinking-water sow
Recording the cow’s water intake real time with flow meter
Establishing a star network with wireless radio frequency module
and simplifying time synchronization problem of the network
Sow individual information is collected and sent to remote monitoring center via network
Achieving automatic monitoring of sow individual drinking behavior.The result shows that the recognition accuracy of drinking sow individual is 100%
node can accurately record amount of drinking water in real time.
