The invention discloses a
human body location detecting device within a
small range. The device comprises a power supply module and is characterized by also comprising an
infrared positioner, an MCU processor and a location information display module. The power supply module powers up the
infrared positioner and the MCU processor. The
infrared positioner is composed of an infrared emitting
diode. The location information display module is composed of a
nixie tube. According to the technical scheme of the invention, the
human body location detecting device is provided with the infrared emitting
diode, thus being simple and easy to operate, free from the influence of the external condition, high in precision and low in cost. Since the location information is shown in the form of high and low levels, a 51-series single-
chip microcomputer is adopted by the MCU processor. In this way, the MCU processor is compatible with multiple platforms. The detection scope of the device can be expanded and contracted. Since the scope
verification of an infrared emitting
diode fixed board unit is conducted based on requirements, the infrared emitting diode fixed board unit can be manufactured to be large or small. The infrared emitting diode-based positioner is used for positioning a
human body within a small area range, so that the device is dismountable, flexible and convenient. The device can be applied in multiple places.
