功率调节方法、装置以及人体安检设备
Abstract:
本发明涉及一种功率调节方法、装置以及人体安检设备，其方法应用于具有毫米波收发装置的人体安检设备或者检测设备，在所述毫米波收发装置的毫米波信号发射链路中设置有可调功率衰减器，所述方法包括：获取预设的湿度传感器对所述毫米波收发装置所处环境湿度进行检测得到的当前湿度值；根据所述当前湿度值确定所述可调功率衰减器的目标功率衰减值，其中，所述目标功率衰减值与由所述环境湿度对毫米波信号引起的功率衰减值的和值为恒定值；控制所述可调功率衰减器将所述可调功率衰减器的功率衰减值调节到与所述目标功率衰减值一致。采用本发明方案，可以在保证成像图像的清晰度的同时使得辐射危害较小。
Abstract(English):

A power adjustment method and apparatus, and a human body security check device. The method is applied in a human body security check device or an inspection device provided with a millimeter wave transceiver (302). An adjustable power attenuator (3013) is provided in a millimeter wave signal transmitting link of the millimeter wave transceiver (302). The method comprises: obtaining a current humidity value by detecting the ambient humidity around the millimeter wave transceiver (302) using a preset humidity sensor (3011); determining a target power attenuation value of the adjustable power attenuator (3013) according to the current humidity value, the sum of the target power attenuation value and a power attenuation value caused to a millimeter wave signal by the ambient humidity being a constant value; and controlling the adjustable power attenuator (3013) to adjust its power attenuation value to be consistent with the target power attenuation value. The solution can reduce radiation hazard while ensuring the definition of an imaged image.
