Wherein:

[0020] The time setting module 11 is provided with a timer 111 and a data storage unit 112, the timer 111 adopts an SVI crystal oscillator as a clock source, and the timer 111 and the data storage unit 112 are electrically connected with the central control module 10 through data transmission lines; the voltage regulation component 12 includes a plurality of voltage regulation modules 121, each voltage regulation module 121 is electrically connected with the corresponding plug-in disc 16 through an independent voltage output line; the voltage detection unit 13 is provided with a plurality of voltage sensors 131 for detecting 5.0V voltage, each voltage sensor 131 is electrically connected with the corresponding plug-in disc 16 through a wire; the wireless communication module 14 is electrically connected with the central control module 10 through a data transmission line, so that the central control module 10 interacts with the display and control terminal 15 through the wireless communication module 14; the display and control terminal 15 has an APP display interface, and the display and control terminal 15 is provided with a display driving line and a touch sensing line connected to the APP display interface, and the display and control terminal 15 is also provided with a data processing and transmission line to interact with the wireless communication module 14.

[0021] In actual operation, first, the hardware connection work of the equipment is carried out, and it is ensured that the SSD is connected firmly and correctly. After completing the hardware connection, the user operates through the APP display interface of the display and control terminal 15, and the user can easily input the required voltage pull-off time and other test parameters on the interface. These parameters are quickly and accurately transmitted to the wireless communication module 14 through the data processing and transmission line of the display and control terminal 15, and the wireless communication module 14 adopts a Wi-Fi communication protocol or a Bluetooth communication protocol, etc., to transmit the data to the central control module 10 in a wireless manner;

[0022] After the central control module 10 receives the test parameters, the control chip with the model number STM32H7 is matched with a voltage stabilizing circuit, which has overvoltage protection, undervoltage protection and ripple suppression functions, so as to ensure that the working voltage of the control chip is stable within a specific voltage range and the control chip operates stably and efficiently; the central control module 10 issues an instruction to the time setting module 11 through a data transmission line with the time setting module 11 according to the received time parameters; the timer 111 in the time setting module 11 uses an SVI crystal oscillator as a clock source. The SVI crystal oscillator is an environmentally friendly crystal oscillator and belongs to a voltage-controlled crystal oscillator. It has the characteristics of high-precision and ultra-small surface mount technology. Its frequency range is 1.000MHz~80.000MHz, the frequency stability can reach ±20ppm, ±25ppm, ±30ppm, ±50ppm, ±100ppm, etc., the power supply voltage supports +2.5V, +3.3V, +5.0V, the working temperature range is -20℃~+70℃ or -40℃~+85℃, and the aging rate is ±3ppm / year maximum. It can meet the requirements of the timer 111 for different frequencies and accuracies and is suitable for various test equipment. At the same time, the data storage unit 112 of the time setting module 11 is used to store the time parameters set by the user and the test records generated subsequently and other information, so as to facilitate subsequent query and analysis.

[0023] In terms of voltage regulation, the central control module 10 issues an instruction to the voltage regulation assembly 12 according to the preset test procedure. Each voltage regulation module 121 of the voltage regulation assembly 12 includes a voltage conversion chip, a power amplifier and a filter circuit connected in sequence. The voltage conversion chip uses LM2596. When it is necessary to adjust the voltage, the voltage conversion chip first converts the input voltage to an appropriate level, the power amplifier can amplify the voltage, and the filter circuit can ensure the stability of the output voltage. Each voltage regulation module 121 is electrically connected to the corresponding plug-in board 16 through an independent voltage output line. This design allows independent and accurate regulation of the voltage of each plug-in board 16, meeting the diversified demand for voltage in different test scenarios.

[0024] During the entire test process, the voltage detection unit 13 is equipped with multiple voltage sensors 131 for detecting 5.0V voltage. The voltage detection unit 13 feeds back the real-time monitored plug-in board 16 voltage data to the central control module 10 through a data transmission line, the central control module 10 records these data in real time, and transmits the data to the display and control terminal 15 through the wireless communication module 14. The voltage change is displayed in the form of a real-time curve on the APP display interface, which is convenient for the user to monitor at any time.

[0025] When the voltage detection unit 13 detects that the voltage of the plug-in board 16 reaches 5.0V, the central control module 10 operates according to the preset test procedure.

[0026] Specifically, the voltage pull-off test procedure includes the following procedure:

[0027] Voltage pull-off test procedure one:

[0028] The central control module 10 sends instructions to the voltage regulation component 12 to stabilize the voltage at 5.0V BIT state, while the time setting module 11 starts timing, and this state lasts for 5 minutes. During these 5 minutes, the voltage detection unit 13 continuously monitors the voltage, and the central control module 10 compares the monitoring data with the target voltage 5.0V in real time. If the deviation exceeds the preset value, an alarm mechanism is triggered immediately, and the display and control terminal 15 sends alarm information to the display and control terminal 15 through the wireless communication module 14, and the display and control terminal 15 reminds the operator in the form of a pop-up window and sound to handle it in time. At the same time, the system automatically records this abnormal situation, including the abnormal time, actual voltage value, deviation, etc.

[0029] After 5 minutes, the central control module 10 sends instructions to the voltage regulation component 12 to adjust the voltage to 4.75V BIT, and the time setting module 11 re-timing, and maintains this state for 5 minutes. Similarly, voltage monitoring and abnormal comparison and processing are continuously carried out during this period.

[0030] Then, according to the above procedure, the voltage is adjusted to 5.25V BIT and maintained for 5 minutes, and the same monitoring and processing operation is carried out.

[0031] Finally, the voltage is restored to 5.0V BIT, and continues until the user sets the time or the number of laps in the APP. During the whole process, the switching of each voltage state and the recording of the duration are stored in detail in the data storage unit 112 of the time setting module 11, and the corresponding voltage data is also recorded completely for subsequent analysis.

[0032] Voltage pull-off test procedure two:

[0033] When it is detected that the voltage of the plug-in disc 16 reaches 5.0V, the central control module 10 instructs the voltage regulation component 12 to set the voltage to 3.3V BIT, and the time setting module 11 timing, and maintains for 5 minutes. During this period, the voltage is strictly monitored, and once the actual voltage deviates from 3.3V by more than the preset value, the alarm and abnormal recording program is started immediately.

[0034] After 5 minutes, the voltage is adjusted to 3.135V BIT and maintained for 5 minutes, and the same strict voltage monitoring and abnormal processing is carried out.

[0035] Subsequently, the voltage is adjusted to 3.465V BIT and maintained for 5 minutes, and the monitoring and abnormal processing procedure is repeated.

[0036] Finally, the voltage is restored to 3.3VBIT until a set time or number of turns is reached. The data recording and storage in the entire process is consistent with the process.

[0037] Through the above series of detailed and rigorous operation processes, the one-stop BITS / H2 aging voltage bias test system can efficiently and accurately complete the aging voltage bias test work of a large number of SSD devices, and fully demonstrates its significant advantages and practical value in the field of electronic device testing.
