Research On Wireless Transmission Technology Of Current Transformer For Energy Efficiency Management

With the rapid development of China's economy,the power consumption demand of all walks of life is more and more.The phenomenon of power shortage is becoming more and more prominent.Energy saving has become the focus of the whole society.The operators in order to actively respond to the call of energy-saving policies,the need for site energy consumption in node detection,to ensure the smooth development of energy-saving work.As the base station energy management work there are many nodes,wiring complicated,part of the aging line,not all of the broken-line power monitoring,the need for a convenient installation,low-cost energy monitoring device.In order to adapt to a special installation environment,current transformer and voltage transformer to be off-site acquisition of current and voltage,and through synchronization,transmission and calculation to achieve real-time monitoring of electricity purposes.Therefore,this topic presents a wireless synchronous power monitoring system.Through the comparison and analysis of the two key technologies in the wireless synchronous system,we choose the local network synchronization method and the Zigbee wireless transmission technology to design the whole wireless synchronization system.The whole wireless synchronization system is designed on the hardware,and the function and the realization of the system are analyzed.The main wireless module and the terminal wireless module are designed with LPC2214 as the core processor.Then,the circuit design of each part of the module,the function of the circuit and the selection of the devi ce are introduced in detail,and completed the entire wireless synchronization system software design,to achieve its various parts of the function and were tested.The feasibility of the system is verified by the comparison between the test results and th e data.
