Description

Technical Field

[0001] This utility model belongs to the field of fast charging technology, and in particular relates to a portable device for detecting deception and monitoring fast charging protocols. Background Technology

[0002] With the continuous development of fast charging technology, the variety of fast charging power adapters on the market is also increasing. People urgently need a small and portable instrument to test which fast charging protocols a current fast charging power adapter supports, and to monitor which fast charging protocol a power adapter uses when charging mobile devices. At the same time, in the field of electronic technology, people also need a portable instrument with various USB input and output measurement interfaces to easily connect to the product under test to check for abnormal voltage and current, and to monitor whether the voltage and current data are abnormal. If an incompatible fast charging power adapter is used, not only will the fast charging effect not be achieved, but it may also damage the battery of electronic devices and shorten the battery life.

[0003] Currently, similar products on the market support too few decoy detection fast charging protocols. For example, they only support PD or QC decoy detection and do not support Huawei SCP or Xiaomi proprietary protocol decoy detection. They can either only perform fast charging protocol detection or only perform simple voltage and current monitoring. They cannot simultaneously meet the needs of current detection, decoy detection, and monitoring of fast charging protocols. At the same time, traditional detection equipment has a large accuracy error in monitoring voltage and current, which affects debugging work in the field of electronic technology. In addition, these devices are generally bulky and inconvenient to carry, and cannot be well adapted to the fast-paced life and diverse work scenarios of modern times.

[0004] To address these issues, we provide a portable device for detecting deception and monitoring fast charging protocols. Utility Model Content

[0005] The purpose of this invention is to provide a portable device for detecting deception and monitoring fast charging protocols, which solves the problem that existing detection devices support too few deception detection fast charging protocols, have large errors in the accuracy of monitoring voltage and current, and affect debugging work in the field of electronic technology.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a portable device for detecting deception and monitoring fast charging protocols, comprising a microcontroller module, a fast charging power adapter, and a power-consuming device. The input terminal of the microcontroller module is unidirectionally electrically connected to a power supply module. The input terminal of the power supply module is unidirectionally electrically connected to a USB input measurement interface. The output terminal of the USB input measurement interface is unidirectionally electrically connected to a protocol monitoring module. The output terminal of the protocol monitoring module is bidirectionally electrically connected to the input terminal of the microcontroller module. The output of the B input measurement interface is unidirectionally electrically connected to a protocol detection decoy module. The output of the protocol detection decoy module is bidirectionally electrically connected to the input of the microcontroller module. The output of the microcontroller is bidirectionally electrically connected to a voltage and current detection module. The output of the voltage and current detection module is unidirectionally electrically connected to a USB output measurement interface. The output of the microcontroller module is bidirectionally electrically connected to an HID computer data interface module. The microcontroller module, power supply module, fast charging protocol detection decoy module, fast charging protocol monitoring module, current and voltage detection module, USB input measurement interface, and USB output measurement interface are all mounted on a built-in circuit control board. This convenient device is controlled by a microcontroller and works in conjunction with the built-in circuit control board... The charging protocol detection and decoy circuit can detect and decoy various fast charging protocols supported by the fast charging power adapter. It can also monitor which fast charging protocol is used between the fast charging power adapter and mobile devices. At the same time, it can monitor data such as voltage, current, and power. It also supports detecting whether the CC line has Emarker core information, displaying voltage and current waveforms, and supporting functions such as detecting the approximate capacity of the mobile phone battery. It supports online detection and decoy of multiple fast charging protocols such as QC / PD / UFSC / SCP / FCP / AFC, and can also monitor the fast charging protocol used by the fast charging power adapter when charging the mobile phone. It supports online statistics of the power bank's battery capacity information and reading the Emarker core information of the CC line.

[0008] The fast charging protocol monitoring module uses a network of four 300K resistors to divide the voltage, and then uses the PC5 / PC4 pins of the microcontroller as ADC pins to collect the voltage of the D+ / D- pins of the USB input interface under different fast charging protocols. PA0 / PB5 / PB4 are used as GPIO pins to capture the pulse count of the D+ / D- / ID pins of the USB input interface under different fast charging protocols. The two are combined to analyze which fast charging protocol is being used (such as Qualcomm's QC, Huawei's SCP, etc.). If it is the PD fast charging protocol, the dedicated PD chip FUSB302 monitors the CC1 pin of the USB input interface. Then, the microcontroller interacts with the FUSB302 through the PB10 / PB11 I2C pins to obtain the monitoring results of the PD fast charging protocol.

[0009] The fast charging protocol detection decoy module uses two sets of 10K / 3K resistors to output different 0 and 1 high and low levels (e.g., 0.0V / 0.7V / 3.3V) to the D+ / D- pins of the USB input interface via PA9 / PB5 and PA0 / PA10 of the microcontroller. This simulates different voltages (e.g., 0.0V / 0.7V / 3.3V) to detect and decoy the Qualcomm QC fast charging protocol. It also uses PA9 and PA10 as GPIO pins to simulate a standardized sequence of signals to the D+ / D- pins of the USB input interface, thus enabling Huawei's SCP fast charging protocol detection. Finally, it converts PA9 and PA10 into UART pins, allowing serial data to be sent to the D+ / D- pins of the USB input interface. The + / D- pins are used to trick and detect VIVO's VFCP fast charging protocol; the microcontroller's PA9, PA10, and PB4 are used as GPIO pins to simulate the standard sequence and send it to the D+ / D- pins of the USB input interface to realize OPPO's VOOC fast charging protocol detection; if it is the PD fast charging protocol, a dedicated PD chip FUSB302 is connected to the CC1 pin of the USB input interface, and then the microcontroller exchanges data with FUSB302 through the two I2C pins PB10 / PB11 to trick and detect the PD fast charging protocol. All the protocols obtained from the trick detection are finally detected by the TPA626 dedicated 16-bit ADC chip to check whether the tricked voltage and current reach the trick value.

[0010] The present invention is further configured such that the input terminal of the microcontroller module is unidirectionally connected to a button module, and the number of button modules is three. The output terminal of the button module is unidirectionally electrically connected to the input terminal of the microcontroller module. The button module is mainly composed of three resistors, which are then connected to the PA4 pin of the microcontroller through KEY_ADC. This microcontroller pin acts as an ADC to collect the voltage when different buttons are pressed, thereby determining which button is pressed and realizing human-computer interaction.

The high-definition IPS display screen is model LH096T-IG01. The high-definition IPS screen displays fast charging protocol information and various related information such as voltage and current for detection, deception, and monitoring. The screen display is delicate, rich, and has a good effect.

[0012] The present invention is further configured such that the USB input measurement interface and the USB output measurement interface are both connected to the built-in circuit control board by soldering, the power adapter is connected to the USBA input measurement interface, the fast charging power adapter is usually a fast charging head from various mobile phone manufacturers, which supports fast charging protocols such as PD / QC / UFCS, and the mobile phone and data cable are also mobile phones and data cables produced by common mobile phone manufacturers on the market.

[0013] The present invention is further configured such that the voltage and current detection module adopts a 16-bit dedicated ADC chip of TPA626, and interacts with the microcontroller through the I2C pin. The voltage and current detection module collects the voltage and current data signals of each USB input and output measurement interface, and then displays them on the high-definition IPS screen to give users an intuitive display of the voltage and current of the fast charging power adapter and the mobile phone and other electrical devices at that time.

[0014] The present invention is further configured such that the power supply module is composed of an MD833A power chip, a filter capacitor and a diode. The power supply module mainly uses the MD833A dedicated power chip, supplemented by some filter capacitors and diodes, to improve the stability of the power supply module.
