The invention provides a circuit and a method for improving infrared identification sensitivity, a mobile power supply and mobile power supply leasing equipment. The circuit comprises an infrared receiving module, the anode of the infrared receiving module is directly or indirectly connected with a power voltage input end, the cathode of the infrared receiving module is directly or indirectly connected with the input end of a processor and one end of a resistor, and the other end of the resistor is directly or indirectly grounded; the voltage of the power supply voltage input end and the voltage capable of being borne by the input end of the processor are increased, the voltage of the input end of the processor is equal to or smaller than the maximum voltage capable of being borne by the power supply voltage input end, and the preset threshold value ranges from 2 V to 6 V. According to the invention, the identification sensitivity of an infrared receiver to an infrared light signal is improved.

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...
