Research And Design Of Nuclear Power Equipment Status Wireless Low-power Monitoring Device

The face of the growing energy crisis in today’s society, nuclear energy as anefficient energy some of the world’s energy consuming countries use, the world hashundreds of nuclear power plants. However, nuclear tremendous energy to the world,along with the potential hazards. Some well-known nuclear accidents such as Chernobyl,Fukushima nuclear power plant accident are painful lessons: nuclear power plant safetyis the top priority in the development and utilization of nuclear energy; nuclear powerplant in the event of a major accident, will be on the surrounding environment a longtime can not be recovered due to trauma. In order to ensure the safe and stable operationof the nuclear power equipment, it is very necessary to monitor its status. Mainly usedin the nuclear power plant is wired monitoring, the higher the cost, the small scope ofmonitoring; comparison with the wired monitoring, wireless monitoring has theadvantages of low cost, small size, and a wide range of monitoring, wireless monitoringalso have to face the problem of energy consumption. Demand for wireless monitoringwireless sensor network (WSN) technology used in the nuclear power plant statusmonitoring complement wired detected, reduce monitoring costs. The same time, energyissues for wireless monitoring node low-power design and design confession module toextend battery life.WSN technology in military, industrial, agriculture and other fields more widely,but in this sensitive area applications of the nuclear power plant is still in theexploratory stage, nuclear power equipment condition monitoring study, the maincontents include:(1) To discuss energy issues faced by the wireless sensor network applications:Applications poor environment, difficult to achieve large-scale change the battery.(2) The case of nuclear power plant were analyzed, identified by the rotatingmachinery within the nuclear power plant as a detection object, the monitoringparameter is the vibration data, coupled with the temperature data as a supplement.(3) To study the energy consumption of the wireless sensor network analysis andexplore the specific energy-saving methods and key technologies based on energy consumption distribution.(4) According to the basic method of low-power wireless sensor networks, basedon the MC13224chip design network node cluster member nodes, the cluster headnodes, sink nodes to achieve a low-power operating mode of the cluster head and clustermembers: sleep and wake-up time synchronization. Based on the ADXL345three-axisaccelerometer designed low-power vibration sensing module drive DS18B20low-power temperature sensor module, and two sensing module-based software.(5) Several environmental energy harvesting technology, according to this articlethe actual application, specifically discussed the vibration power generation technology,design LTC3588-1vibration energy harvesting module.(6) Designed experimental aspects of the total power consumption of the wirelesssensor network node is equipped with a vibration module and temperature sensingmodule test, contrast before and after the early low-power energy consumption andcompared with other types of WSN node energy consumption, while the type ofcommunication environment under the communication ability of the test, hydropowergenerators device status data to monitor, test In addition to the power generationcapacity of the vibration generating modules.
