智能配电箱还包括配套使用的手持仪，手持仪为智能手机移动终端，可扫描二维码 加密验证单元生成的二维码，实现手持仪与IoT自组网通信模块的自动组网。
智能锁含有电池和电机，在二维码加密验证单元验证后，可以控制智能锁的开关，从而打开或关闭机柜，保护机柜安全，可完全替代机械锁，这样工作人员就不用佩戴机 械钥匙了。智能锁选用金万码科技公司出产的WM-2000B-XBS型无源电子配电箱锁。
二维码加密验证单元选用深圳远景达(RAKINDA)LV4500嵌入式二维码模块，其自带 显示单元(屏幕)来显示生成的二维码，便于手持仪扫描。
二维码加密验证单元负责生成携带有开锁信息的二维码，通过手持仪(智能手机移 动终端)，扫描二维码后，通过IoT自组网通信模块连接，无需网络，经二维码加密验证单元验证，可以控制智能锁的开关，达到扫码自动开锁的作用。智能开锁单元自组网加 密开锁框架图如图5所示。
位置传感器选用深圳市旭达科技有限公司出产的ZLDS100激光位移传感器。位置传 感器采集配电箱中各个断路器开合状态，通过A/D转换器及IoT自组网通信模块，将信息传输至存储芯片，经手持仪扫描二维码，通过IoT自组网通信模块连接，可以获得存 储芯片中存储的断路器开合状态。
IoT自组网通信模块选用深圳立创商城SIM7070G芯讯通NB-IoT模组。其中，IoT自组网通信模块负责使用窄带物联网技术进行内部通信，由于智能配电箱是通过传输少量数据来实现内部通信的，因此可以通过采用更好的MCS(Modulation and Coding Scheme：调制与编码策略)来达到降低传输链路功耗的目的，通过传输功率Ptx来评价功耗，传 输功率Ptx的计算公式为:

根据研究仿真数据，用于评估设备能耗实验的功率参数中PTx＝792mW、PRx＝72mW、 PIdle＝22mW和PSleep＝18μW。设置电池容量为18000J(5Wh)，164dB损耗情况下运行， 同时忽略电池泄漏影响、温度影响和峰值电流情况。
不同eDRX模式下的电池运行时间如图3所示，PerfectXC为最佳运行模式，LowPowerXC为低功耗运行模式，Optilowcostclock为优化功耗模式，Unoptilowcost为 未优化功耗模式。不同eDRX模式下的电池寿命情况。可看出，低功耗模式更适合物联网。
不同数据传输量和网络覆盖场景优劣环境下对电池寿命损耗的影响如图4所示。从 图4中可得出，对于小数据长度，NB-IoT具有更大的电池寿命。通过实验仿真可见，所 研究超窄频通讯网络更利于在低功耗情况下智能配电箱内部网络传输。
NB-IoT在PSM和eDRX均部署的情况下，更有利于智能配电箱内部组网并长期、稳定传输数据。
实施例2：
