Development Of A Monitoring System For Power Cable Temperature Based On Zigbee Technology

Electric power is the foundation of the national economy and the pillar, is to maintain thenormal operation of industrial and economic steady and sustained development of thefundamental guarantee of electric power system, safety and stability to the relationshipbetween bearing; With the development of urban construction, power cable to the safe andreliable power supply for urban beautification and advantages have been applied more andmore, so the power system for the safety of the cable line power supply and power supplyreliability requirements of more and more strict, traditional regular blackouts in the practice ofpreventive test already cannot satisfy the requirement of high power grid reliability.The surface temperature of the power cable reflects the operation of cable. Whether aload operation or cable running environment change or cable line itself insulation fault, cancause cable surface temperature changes, so monitoring cable surface temperature can in timefound that cable abnormalities, take timely measures, can avoid accidents; In view of this, thedevelopment of a power cable to temperature monitoring system has a very importantsignificance and meaning.This paper through to the wireless sensor network research, based on the development ofhigh voltage power cables Zigbee local temperature measurement system, technology of shortZigbee wireless sensor networks with high efficiency, low complexity, communication, lowpower consumption, low rate, low cost, safety higher many advantages. Accord with cablejoint more. Need more monitoring node, short transmission delay and very low powerconsumption requirements: on the other hand, the cable temperature monitoring need the datatransmission bandwidths demand less, not high. Based on the wireless sensor networktechnology ZigBee can form a flexible monitoring node cluster. Comply with the temperatureof the cable on-line monitoring system requirements.Paper wireless sensor networks, GPRS two kinds of wireless transmission technology toeffectively integrate together to achieve a power cable temperature monitoring and earlywarning; system uses ZigBee module and sensor module terminal nodes, the temperatureparameters of the monitor cable to real-time acquisition andtransmitted to the coordinator node, these data from the coordinator node through the wireless base stations and the Internetthrough GPRS module to transfer data to the monitoring center for data storage and statisticalanalysis. Using TI’s ZigBee wireless sensor networks to solve the program T2530temperaturesensor D18B20, to form a star network structure, GPRS data transmission using a SIM300module; paper gives the hardware and software design and implementation of wireless sensornetwork nodes for temperature monitoring of power cables. System has real-time curvepreservation, local and remote transmission of the remote temperature alarm and data.Paper the final test results to prove it to meet the basic cable temperature measurementsystem requirements, the monitoring system sensor data acquisition system is stable, flexiblenetwork nodes, while addressing the traditional limitations of on-site monitoring system basedon wired to the power cable the temperature monitoring provides an effective means ofmonitoring.
