Abstract

The invention is applicable to the field of mobile power supply rental, and provides a circuit and method for improving infrared recognition sensitivity, a mobile power supply and mobile power supply rental equipment. The negative electrode of the processor is directly or indirectly connected to the input terminal of the processor and one end of a resistor, and the other end of the resistor is directly or indirectly grounded; the voltage of the input terminal of the power supply voltage and the voltage that the input terminal of the processor can withstand are increased, and the processor The voltage at the input terminal of the power supply voltage input terminal is equal to or less than a preset threshold value, and the preset threshold value is between 2-6V. The invention improves the recognition sensitivity of the infrared receiver to the infrared light signal.

Description

technical field [0001] The invention belongs to the field of mobile power supply rental, and in particular relates to a circuit and method for improving infrared recognition sensitivity, a mobile power supply and mobile power supply rental equipment. Background technique [0002] The module and mobile power of the mobile power rental equipment that have added infrared communication function to identify information such as mobile power identity, when the power of the mobile power is low and the infrared light signal sent by the infrared transmitter is weak, the receiver that receives the light signal The infrared receiver may not be able to recognize the weak light signal, which will cause the communication between the module and the power bank to fail. In addition, in the production process, the relative positions of the infrared emitter and the infrared receiver cannot be accurately one-to-one, which will also weaken the intensity of the optical signal received by the infra...
