【摘要】：发展无线传感器网络技术已经成为国家的战略目标,相关新兴产业被国家重点扶持。433MHz作为国内常用的无线数据采集网络工作频段,被广泛应用在抄表行业中。但无线传感器网络固有的能耗较大,网络设计复杂,受周遭环境影响较大等缺陷,限制了其应用范围。本文设计的无线数据采集系统是基于TI公司CC1110射频芯片以及TI公司的SimpliciTI协议,本文首先完成无线传感器网络节点中节点的硬件原理图设计和PCB电路板制作,此硬件包括电源管理,JTAG接口电路,射频等模块,采用核心板和底板相分离的PCB设计方式。本文通过对上述电路进行详细的分析后,借助SmartRF studio软件测试通信质量,如在不同功率下的传输数据的有效距离,在同一功率下的数据丢包率,正确率等参数,测试表明,电路具有良好的射频参数,同时也对CC1110芯片各种模式下的电能消耗做了实际的测试,证明满足低功耗的需求。再次,本文借鉴了 SimpliciTI协议的网络特点和拓扑结构,提出了一种基于SimpliciTI协议的串状网络结构。在该结构中通过对不同的节点分别下载不同的程序,分别实现终端节点信息采集和发送,路由节点数据转发,以及数据中心接受数据的功能。根据系统低功耗的需求,终端节点采用休眠-唤醒的传感器网路低功耗工作模式。本文将该系统应用在冬季小区住户室温采集中,依据应用环境的特殊性,设计合适的节点放置和路由规划,通过测温模块定时采集温度信息,发送到始终处于工作状态的路由节点或者数据中心,在上位机上显示和存储。此外上位机还具有住户信息查询,住户历史温度数据查询等功能。本文的系统提供了终端采集,路由规划,数据中心监测,类数据库服务等一体的解决方案。
[Abstract]:The development of wireless sensor network technology has become the country's strategic objectives, related to emerging industries is the national key support.433MHz as the commonly used wireless data acquisition network band, is widely used in industry. But the natural reading of the wireless sensor network energy consumption, network design complexity, greatly influenced by the surroundings and other defects, limiting its application the range of wireless data acquisition system. This paper is the design of TI CC1110 RF chip and TI, based on SimpliciTI protocol, this paper completes the node node in a wireless sensor network hardware principle diagram design and PCB circuit board production, the hardware includes power management, JTAG interface circuit, RF module, the design of the PCB core board and the bottom of phase separation. In this paper, through the detailed analysis of the circuit, with the help of SmartRF Studio software testing communication quality The effective distance, such as under different power data transmission, data packet loss rate under the same power, the correct rate parameters of test show that the circuit has good RF parameters, but also on the mode of CC1110 chip under the power consumption of the actual test, that meet the demand of low power dissipation. Again, this paper draws on the characteristics of network topology and SimpliciTI protocol, proposes a cluster network structure based on SimpliciTI protocol. In this structure by downloading different programs on different nodes, respectively, to achieve information acquisition and transmission terminal node, routing node data forwarding, and data center according to receive data. Low power requirement of the system, the terminal node by sleep wake up the sensor network low power mode. The system can be used in the winter residential tenants room temperature collection, according to the application Special environment, design the appropriate node placement and routing planning, collecting temperature information through the temperature measurement module timing, sent to work all the time the routing node or the data center, displayed on the host computer and storage. In addition the PC has household information, household history temperature data query. This system provides the acquisition terminal, route planning, data center monitoring solution database services development.
