example 1

[0070] Please refer to Figure 4a , which is a schematic structural diagram of one of the implementation manners of the voltage and current acquisition device according to the embodiment of the present invention. Such as Figure 4a as shown,

[0071] The voltage and current acquisition device 33-1 (indicated by reference numeral "33-1" here is an implementation of the voltage and current acquisition device 33) includes a first input terminal 33-10, a first output terminal 33-11 , the first resistor R1, the second input terminal 33-12, the second output terminal 33-13, the second resistor R2, the first analog-to-digital converter 33-14, the second analog-to-digital converter 33-15, the third analog A digital converter 33-16, a fourth analog-to-digital converter 33-17 and a voltage and current processor 33-18;

[0072] A first resistor R1 is connected between the first input terminal 33-10 and the first output terminal 33-11 (that is, both the first input terminal 33-10 and t...

example 2

[0083] Please refer to Figure 4b , which is a schematic structural diagram of the second implementation manner of the voltage and current acquisition device according to the embodiment of the present invention. In this example, the voltage and current acquisition device includes:

[0084] a first input terminal, a first output terminal, a first resistor, a second input terminal, a second output terminal, a second resistor, an analog-to-digital converter, and a voltage-current processor;

[0085]A first resistor is connected between the first input end and the first output end, both the first input end and the first output end are connected to the analog-to-digital converter, and the second input end is connected to the second output end. Two resistors, the second input terminal and the second output terminal are both connected to an analog-to-digital converter, and the analog-to-digital converter is connected to a voltage and current processor;

[0086] Wherein, the analog-...

example 3

[0090] Please refer to Figure 4c , which is a schematic structural diagram of the third implementation manner of the voltage and current acquisition device according to the embodiment of the present invention. The difference between this example and Example 2 is that the voltage and current acquisition device also includes a first differential comparison circuit and a second differential comparison circuit;

[0091] The first output terminal is connected to the analog-to-digital converter through the first differential comparison circuit;

[0092] The second output end is connected to the analog-to-digital converter through the second difference comparison circuit.

[0093] Thus, the analog-to-digital converter can collect the voltage of the first input terminal and the first output terminal at the same time, and the voltage of the second input terminal and the second output terminal at the same time, thereby improving the reliability of the voltage collected by the analog-t...

Abstract

The invention provides a mobile phone charging detecting system and a mobile phone charging detecting method. The mobile phone charging detecting system comprises a mobile phone, a charger, a battery, a voltage and current collecting device and a display device, wherein the charger is connected with the mobile phone; the mobile phone is connected with the battery through the voltage and current collecting device; the voltage and current collecting device is connected with the display device; the voltage and current collecting device acquires the value of real-time voltage flowing to the battery from the mobile phone and the value of the corresponding current; and the display device displays the value of the real-time voltage flowing to the battery from the mobile phone and the value of the corresponding current. Because the voltage and current collecting device acquires the real-time value of the voltage flowing to the battery from the mobile phone and the value of the corresponding current, and the display device displays the value of the real-time voltage flowing to the battery from the mobile phone and the value of the corresponding current, a large quantity of pairs of voltage values and current values can be acquired, a mobile phone charging process can be obtained in detail, and the reliability on mobile phone charging detection is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a mobile phone charging detection system and method. Background technique [0002] Usually, after the design of the mobile phone is completed, multiple functions and performance tests need to be performed on it. Among them, one test is the test of mobile phone charging performance. Through this test, it is mainly to understand whether the voltage and current change characteristics of the battery meet the design expectations during the charging process of the mobile phone.
