资料介绍

在节点现有功能基础上进行外围电路功能扩展是传感器网络应用开发中的常见问题之一。本文以JN5139系列节点为基础,用测量范围较大的高温采集电路,替换了原有的常温传感器;配备了蓄电池电压检测电路,使得监测中心能及时了解节点能量供应情况;通过纽扣电池为节点时钟芯片提供电源,保证节点时钟计时准确性;采用GPRS开关控制电路,降低了汇聚节点能量损耗;设计的看门狗控制电路,提高了节点工作的可靠性和稳定性。

Extending the function of the peripheral circuit based on the existing features of wireless sensor network nodes is one of the frequently asked questions in the development of sensor network applications. In this paper which is based on JN5139 series nodes, we replace the original temperature sensor by a wider range of high-temperature data acquisition circuit. A battery voltage detection circuit is equipped in order to make the monitoring center keep the abreast of the node energy supply. Button battery is used to provide power for clock chip of node to ensure the timing accuracy of the node clock. We use GPRS switching control circuit to reduce the energy loss of coordinator. The design of watchdog control circuit improves the reliability ...
