Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
The first embodiment is as follows:
referring to fig. 1, a first embodiment of the present invention provides a circuit for improving infrared identification sensitivity, where the circuit includes an infrared receiving module whose positive electrode is directly or indirectly connected to a power supply voltage input end, a negative electrode of the infrared receiving module is respectively directly or indirectly connected to an input end of a processor and one end of a resistor R1, and another end of the resistor R1 is directly or indirectly grounded;
the voltage of the input end of the power supply voltage and the voltage born by the input end of the processor are improved, the voltage of the input end of the processor is equal to or less than a preset threshold value with the maximum voltage born by the input end of the power supply voltage, and the preset threshold value is 2-6V.
In the first embodiment of the present invention, the infrared receiving module is an infrared receiving tube D1.
The working principle of the circuit is as follows:
the voltage of the power supply voltage input end and the voltage which can be born by the input end of the processor are improved; when the bearable voltage value of the input end of the processor is increased to a value close to the power supply voltage, even if the resistance is increased due to the fact that the optical signal received by the infrared receiving module is weak, the voltage required for identifying the optical signal is increased, because the infrared receiving tube is directly connected with the processor, the voltage on the circuit where the infrared receiving module is located is not provided with a voltage dividing resistor, the voltage on the circuit where the infrared receiving module is located can be completely used for supplying power for the infrared receiving module to identify the infrared optical signal, therefore, the voltage of the infrared receiving module is enough to identify the weak infrared optical signal, and the identified optical signal result is sent to the processor connected with the infrared receiving module.
For example: when the voltage threshold is 5.6V, the voltage of the input end of the power supply voltage is increased to 5.2V, so that the debugging range of high-level voltage is enlarged, and the voltage value on the infrared receiving module is increased. Therefore, even if the infrared receiving module receives a weak optical signal to cause the resistance to increase and the voltage required for identifying the optical signal to increase, the voltage on the circuit on which the infrared receiving module is arranged can be completely used for supplying power to the infrared receiving module to identify the infrared optical signal because the infrared receiving tube is directly connected with the processor and the voltage on the circuit on which the infrared receiving module is arranged does not have a voltage dividing resistance, so that the voltage on the infrared receiving module is enough to identify the weak infrared optical signal, and the identified optical signal result is sent to the processor connected with the infrared receiving module.
Or when the voltage threshold is 3V, the voltage of the input end of the power supply voltage is increased to 2.5V, so that the debugging range of the high-level voltage is enlarged, and the voltage value on the infrared receiving module is increased. Therefore, even if the infrared receiving module receives a weak optical signal to cause the resistance to increase and the voltage required for identifying the optical signal to increase, the voltage on the circuit on which the infrared receiving module is arranged can be completely used for supplying power to the infrared receiving module to identify the infrared optical signal because the infrared receiving tube is directly connected with the processor and the voltage on the circuit on which the infrared receiving module is arranged does not have a voltage dividing resistance, so that the voltage on the infrared receiving module is enough to identify the weak infrared optical signal, and the identified optical signal result is sent to the processor connected with the infrared receiving module.
Example two:
referring to fig. 2, a second embodiment of the present invention provides another circuit for improving infrared identification sensitivity, where the circuit includes a resistor R1 having one end directly or indirectly connected to a power supply voltage input end, the other end of the resistor R1 is respectively directly or indirectly connected to an anode of an infrared receiving module and an input end of a processor, and a cathode of the infrared receiving module is directly or indirectly grounded;
the voltage of the input end of the power supply voltage and the voltage born by the input end of the processor are improved, the voltage of the input end of the processor is equal to or less than a preset threshold value with the maximum voltage born by the input end of the power supply voltage, and the preset threshold value is 2-6V.
In the second embodiment of the present invention, the infrared receiving module is an infrared receiving tube D1.
Example three:
the third embodiment of the invention provides a mobile power supply which comprises the circuit for improving the infrared identification sensitivity.
Example four:
the fourth embodiment of the invention provides the mobile power supply leasing equipment which comprises the circuit for improving the infrared identification sensitivity.
Example five:
referring to fig. 3, a fifth embodiment of the present invention provides a method for improving infrared recognition sensitivity, including:
s1, an infrared receiving module of the circuit for improving the infrared identification sensitivity receives an optical signal transmitted by an infrared transmitting module;
s2, calculating a difference value of a low-level wavelength period and a high-level wavelength period of the optical signal by the processor;
and S3, judging whether the difference value is smaller than a preset threshold value by the processor, and if so, increasing the error range of the low-level wavelength period or the high-level wavelength period.
In the fifth embodiment of the present invention, the preset threshold is equal to a minimum difference between a low level wavelength period and a high level wavelength period of the identifiable optical signal.
For example: when the high-level wavelength period is 0.5ms and the low-level wavelength period is 0.62ms, the difference between the high-level wavelength period and the low-level wavelength period is only 0.12ms, and the identification difficulty is high. The low-level wavelength variation period can be lengthened to an acceptable error range of 0.62 +/-0.1 ms, the difficulty in identifying the low-level wavelength period is reduced, as long as the period is detected to be a value between 0.52 ms and 0.72ms, the low-level wavelength period is detected, and the high-level wavelength period is detected. In the same way, the acceptable error range of the high-level wavelength period can be lengthened by the same method, so that the effect of improving the identifiability of the high-level period and the low-level period is achieved.
Example six:
a sixth embodiment of the present invention provides a computer-readable storage medium, where a computer program is stored, and when the computer program is executed by a processor, the steps of the method for improving the infrared recognition sensitivity are implemented.
Example seven:
referring to fig. 4, a mobile power supply 100 according to a seventh embodiment of the present invention includes: one or more processors 101, a memory 102, and one or more computer programs, the processors 101 and the memory 102 being connected by a bus, wherein the one or more computer programs are stored in the memory 102 and configured to be executed by the one or more processors 101, the steps of the method of improving infrared recognition sensitivity being implemented when the computer programs are executed by the processors 101.
Example eight:
referring to fig. 5, an eighth embodiment of the present invention provides a portable power source rental apparatus 200, including: one or more processors 201, a memory 202, and one or more computer programs, the processor 201 and the memory 202 being connected by a bus, wherein the one or more computer programs are stored in the memory 202 and configured to be executed by the one or more processors 201, the processor 201 implementing the steps of the method of improving infrared recognition sensitivity when executing the computer programs.
