摘要 养猪业是我国养殖业的支柱产业，而产房是猪场最关键的一个环节，哺乳仔猪成活率是反应养殖场生产水平的一个重要指标。管理不当导致仔猪被压、咬、踩是造成仔猪死亡的重要原因。现有产房监控系统多侧重于仔猪健康状况监测，对上述问题的解决方法依赖于猪舍硬件结构设计。为此，本文提出一种基于无线传感器网络（WSN）的种猪产房监控系统。
系统采用OV7670摄像模组、驻极体话筒、UTC-4432射频模块以及MSP430系列单片机构建传感器节点，实现对仔猪活动的实时监测。论文从工作原理、关键技术、硬件选型以及软件流程等方面对系统进行详细描述。着重介绍了两个关键技术：一是图像编码压缩。由于图像数据量大和通信带宽的限制，在图像传输前需对其编码压缩。论文对所选用的JPEG标准编解码过程进行详细阐述。二是低功耗实现。由于传感器节点能量有限，因此降低系统功耗十分关键。论文从硬件选型和软件控制两方面入手，来降低系统功耗。
该系统通过采集声音和图像信息对仔猪异常情况进行判定，实现对初生仔猪的实时监控，弥补了人工管理的缺陷。同时对传感器节点低功耗问题做出详细解释，延长系统寿命。基本达到设计要求。

Monitoring System of the Sow Delivery Room Based On WSN
Abstract The pig industry is a pillar industry of China aquaculture, and the delivery room is the key to the farm, piglet survival rate is one of the most important index of the production level of a farm. The inappropriate management that lead to the pressure,and bite on the piglets make a huge contribution to the death. The most current delivery room monitoring systems are focused on monitoring the health condition of piglets, and methods to solve the problem depends on the design of the hardware structure of pigsty. Therefore, this paper presents a pig delivery room system monitoring which based on the wireless sensor network (WSN).
To achieve real-time monitoring of the piglets’ activities,the sensor nodes of the system consist of OV7670 camera module, an electret microphone, UTC-4432 RF module and MSP430 MCU. This paper describes the working principle, key technology, hardware selection and software process of the system in detail. This paper focuses on two key techniques: one is the image compression coding. Because of the large amount of image data and the limitations of the communication bandwidth, the image must be compressed before transmission. And this paper describes JPEG standard in detail. Another is low power consumption. As the energy of the sensor node is limited, it is important to reduce the power consumption of the system. To solve this problem, it should take two aspects including the hardware and software to reduce the power consumption of the system.
The system realizes the real-time monitoring of newborn piglets by means of collecting the sound and image information, and make up for the shortcomings of manual management. At the same time, it makes a detailed explanation of the sensor nodes about the low power consumption, extends the service life of the system. And the basic design requirements has met.
