摘要
文章针对电网企业IT资产管理定位难、追踪难、维护难、管理效率低的问题,首先深入分析WiFi、LoRa、蓝牙、UWB、ZigBee、RFID和U位的定位原理;然后通过在实际应用场景的测试,从组网方式、传输距离、定位精度、单网接入节点容量、标签电池续航能力、标签成本、工作频段、适合应用场景多个角度比较分析7种物联网定位技术的优、缺点;最后从电网企业的应用需求出发,推荐了一种技术组合,实现IT资产的定位与动态跟踪、资产全生命周期的数字化、智能化管理。
In a power grid enterprise, IT asset management has some difficult in positioning, tracking, maintenance, and low efficiency of management. Firstly, positioning principles of WiFi, LoRa, Bluetooth, UWB, ZigBee, RFID and U-bit are analyzed in-depth. Secondly,after evaluating their performance by experiments in production scenario, advantages and disadvantages of seven types of IoT positioning technology are discussed from various perspectives including association mode, transmission distance, accuracy, bandwidth, power consumption, cost, broadband, working scenarios. Finally, based on the application requirements of power grid enterprises, a technology combination is recommended to realize the positioning and dynamic tracking of IT assets, digitalization and intelligent management of the whole life cycle of assets.
