【摘要】：針對傳統(tǒng)樓宇末級配電設備群的手控、用電損耗和無預見性等弊端,設計了一種基于無線傳感器網(wǎng)絡的樓宇末級配電設備群的控制器,該控制器主要由微處理器部分、無線射頻模塊和電源模塊等部分組成.使用NRF905芯片設計的無線射頻集成模塊每隔2s向無線傳感器節(jié)點詢問,檢測到有信號反饋后進入實時控制的工作狀態(tài).使用MSP430F149芯片作為微處理器,和無線射頻模塊共同實現(xiàn)對各個末級配電設備信號的接收、傳送和處理,再通過串口和上位機相連.在實際測試中,盡管有電磁干擾和障礙物等外部因素的影響以及所選芯片的限制,控制器對半徑20m范圍內各個房間用電量數(shù)據(jù)的統(tǒng)計誤差在1%~2%之間.該控制器在無線傳感器自組網(wǎng)構建的樓宇末級配電設備群控制系統(tǒng)中提高了數(shù)據(jù)傳輸效率,實現(xiàn)了數(shù)據(jù)共享,使末級配電設備的遠程監(jiān)控及預測分析具有可行性,且節(jié)能環(huán)保.
[Abstract]:Aiming at the disadvantages of manual control, power loss and unpredictability of the last stage distribution equipment group in traditional buildings, a controller of the last stage distribution equipment group based on wireless sensor network is designed. The controller is mainly composed of microprocessor. Radio-frequency module and power module and other components. The radio frequency integrated module designed with NRF905 chip asks the wireless sensor node every 2s, detects the signal feedback and enters the real-time control state. The MSP430F149 chip is used as a microprocessor, and the radio frequency module is used to realize the receiving, transmitting and processing of the signals of each terminal distribution equipment, and then connected with the host computer through the serial port. In the actual test, despite the influence of external factors such as electromagnetic interference and obstacles, and the limitation of the selected chip, the statistical error of the controller for the data of power consumption of each room within a radius of 20 m is between 1% and 2%. The controller improves the efficiency of data transmission, realizes the data sharing, makes the remote monitoring and prediction analysis of the last stage distribution equipment feasible, and saves energy and environmental protection in the building terminal distribution equipment control system constructed by wireless sensor ad hoc network.
