摘要： 针对传统建筑能耗监测系统存在采集单元功耗高和布线复杂的问题，设计了一种低功耗的无线监测系统。所设计的监测系统包括采集单元、集中器、监测中心和通信网络四部分。其中：采集单元主要由计量电路和BLE（Bluetooth low energy，低功耗蓝牙）通信电路组成，其通过计量电路采集用电设备的能耗数据，并通过BLE通信电路将处理好的能耗数据发送至集中器；集中器主要由BLE通信电路和Wi-Fi通信电路组成，其通过BLE通信电路接收采集单元计量的能耗数据并进行整合、处理，然后通过Wi-Fi通信电路将能耗数据转发至监测中心；监测中心采用B/S（browser/server，浏览器/服务器）架构进行设计，其通过监测界面显示能耗数据并将数据保存在数据库中。所设计的监测系统通过采用BLE和Wi-Fi的通信方式降低了采集单元的运行功耗和布线复杂度，并延长了通信距离；基于B/S架构设计的监测中心可实现跨平台运行，提高了系统的灵活性。测试结果表明，所设计的监测系统的计量偏差率低于5%，通信成功率高于98%，且能够及时监测用电设备的耗能状况，具有较高的实用价值。
Abstract: Aiming at the problems of high power consumption of the acquisition unit and the complex wiring in the traditional building energy consumption monitoring system, a low-power wireless monitoring system was designed. The designed monitoring system included acquisition unit, concentrator, monitoring center and communication network. The acquisition unit was mainly composed of the metering circuit and the BLE (Bluetooth low energy) communication circuit, which collected the energy consumption data of electrical equipment through the metering circuit, and sent the processed energy consumption data to the concentrator through the BLE communication circuit. The concentrator was mainly composed of BLE communication circuit and Wi-Fi communication circuit, which received the energy consumption data measured by the acquisition unit through the BLE communication circuit and integrated and processed it, and then forwarded the energy consumption data to the monitoring certer through the Wi-Fi communication circuit. The monitoring center was designed by B/S (browser/server) architecture, which displayed the energy consumption data through the monitoring interface and saved the data in the database. By using the BLE and Wi-Fi communication mode, the designed monitoring system reduced the operation power consumption of the acquisition unit and the wiring complexity, and prolonged the communication distance; the monitoring center designed based on the B/S architecture could realize cross-platform operation and improved the flexibility of the system. The test results show that the measurement deviation rate of the designed monitoring system is lower than 5%, the communication success rate is higher than 98%, and it can monitor the energy consumption of electric equipment in time, which has high practical value.
