There exist issues of fast environmental degradation, poor intelligence, and low management efficiency with the expansion of breeding deer scale. This paper presents the intelligent monitoring and controlling system for deer based on internet of things (IOT). This system includes multiple wireless sensor network nodes, ZigBee routing nodes, ZigBee Ethernet gateway, server, client and video monitoring devices. Wireless sensor network nodes connects ZigBee Ethernet gateway via ZigBee routing nodes. ZigBee Ethernet gateway access client server to transmit data. Video monitoring device includes video cameras, exchangers, hard disk video recorders and display device. The cameras send the environment information to hard disk video recorder via the exchangers, and the environment parameters can be shown in the screen. Wireless sensor network includes electronic rings, RF read-write monitoring nodes, water and eating monitoring nodes, spray monitoring and controlling nodes, and sunlight monitoring nodes. This system can meet the needs of the deer growth environment, save resources and labor, reduce disease incidence, improve the quality of deer antler and rate of survival, which has important guiding significance to large scale production of deer in the future. Introduction In recent years, the deer production has been paid widely attention. In China, there exist about 600 thousand deer ranking first in the world. Sika deer is the main pharmaceutical economic animals and deer antler have special curative effect, which have been approved by international organizations and experts. As the hometown of Chinese sika deer, Jilin province has the obvious advantages in breeding deer. At present, the deer farms still adopt the traditional breeding method. Unstable product quality, low yield, poor efficiency, severe resource depletion problems exist for a long time due to human factors. A mature system with automatic monitoring and controlling deer breeding environment does not appear. Although the RFID technology based on IOT has been used in the automatic monitoring of pig and cow breeding, the life habit of the deer is different, and deer farms need to simulate the wild environment. So the intelligent monitoring and controlling of deer breeding need to be designed individually. There are rare literatures in China. In 2015 Wu Juxin in Jilin agricultural university wrote a master thesis paper about deer product quality monitoring system based on IOT, which realizes automatic control system in the deer growth environment and precise feeding, and a digital information integrated service management platform was designed [1]. In 2016 Lin Yun uses ZigBee technology to build the sheep farm intelligent sunlight system, and this system can improve the sheep farm environment [2]. In 2015 ZHANG Yan uses IOT technology to build a safety tracebility platform for the whole industry chain of Laiwu pig, in which all data of the whole industry chain including Laiwu pig breeding, cultivation, slaughter, processing, logistics and sales are collected using IOT sensor nodes [3]. In 2013 BAI Hongwu constructs boar management platform based on IOT technology, in which an integrated solution for automatical management, epidemic prevention and food safety of farms is proposed [4]. Zhang Xiaoping studies the intelligent cowshed management system consisting of upper management platform software, transmission equipment, terminal controller and execute components, forming an efficient management mode, which is easy to use and can be 7th International Conference on Mechatronics, Control and Materials (ICMCM 2016) Copyright © 2016, the Authors.
