摘要: 煤矿电气设备可通过集成低功耗蓝牙模块，实现低功耗蓝牙通信功能，但在集成设计过程中，需要根据低功耗蓝牙模块的能耗特征设计电源保护电路、计算电池容量。针对该问题，在不同供电电压和射频功率下，采用高端电流监测芯片ZXCT1010对低功耗蓝牙模块在复位、初始化、广播、连接等不同工作状态下的能耗特征进行了分析。结果表明：低功耗蓝牙模块在射频收发时的能耗较大，且射频收发持续时间短，在射频静态时的能耗小，且射频静态持续时间长；低功耗蓝牙模块能耗受射频功率变化影响小，但受供电电压变化影响较大，供电电压越高，低功耗蓝牙模块各运行状态下的工作电流越大、能耗越大。因此，低功耗蓝牙模块集成应用时，应提供合适的供电电压，但无需限制射频功率。Abstract: Coal mine electrical equipments can realize bluetooth communication function of low power consumption by integrating bluetooth low energy module(BLE). However, in the process of integrated design, power protection circuit and battery capacity should be designed according to energy consumption characteristics of BLE module. For the problem, under different power supply voltage and radio frequency power, high-side current monitoring chip ZXCT1010 was adopted to analyze energy consumption characteristics of BLE module under different working states such as reset, initialization, broadcasting and connection. The results indicate that energy consumption of BLE module in radio frequency(RF) transceiving is high, and RF transceiving duration is short, while energy consumption of BLE module in RF static state is low, and RF static state duration is long. Energy consumption of BLE module is less affected by change of RF power, but is greatly affected by change of power supply voltage. The higher the power supply voltage is, the higher the working current and energy consumption of BLE module in each running state will be. Therefore, suitable power supply voltage should be provided and RF power should not be limited in integration application of BLE module.
