[0039] To more clearly illustrate the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0041] Figure 2 This is a circuit diagram of an automated upgrade control circuit provided in an embodiment of this application. Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] The core of this utility model is to provide an automated upgrade control circuit and fixture.

[0044] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Figure 1 A structural diagram of an automated upgrade control circuit provided in an embodiment of this application is shown below. Figure 1 As shown, the automated upgrade control circuit includes: timer circuit 1, pull-up resistor R, and switching circuit 2. In addition, Figure 1 It also includes: Motherboard 3.

[0046] The connection relationship of its automated upgrade control circuit is as follows: the power supply terminal VCC and the reset terminal RESET of timer circuit 1 are connected to the output terminal of motherboard 3; the input terminal TRIG of timer circuit 1 is connected to the output terminal of motherboard 3 through the pull-up resistor R; the output terminal OUT of timer circuit 1 is connected to the input terminal of motherboard 3 through the switch circuit 2.

[0047] In a specific embodiment, when the timer circuit 1 in the automated upgrade control circuit is connected to the output terminal of the motherboard 3 via the power supply terminal VCC, the reset terminal RESET, and the input terminal TRIG, the automated upgrade control circuit is in a powered-on state. The output voltage of the motherboard 3 supplies power to the timer circuit 1 through the power supply terminal and the reset terminal; at the same time, the output voltage of the motherboard 3, through the resistance value of the pull-up resistor R, causes the input terminal of the timer circuit 1 to reach a preset voltage. When the input terminal TRIG of the timer circuit 1 reaches the preset voltage, the output terminal OUT of the timer circuit 1 outputs a high-level signal, thereby driving the switch circuit 2 to conduct; since the switch circuit 2 is connected to the output terminal OUT of the motherboard 3, when the switch circuit 2 is conducted, it will pull down the output voltage of the motherboard 3.

[0048] It should be noted that the specific value of the preset voltage is related to the input voltage and the resistance value of the pull-up resistor R, and can be set by the user according to their needs.

[0049] This utility model provides an automated upgrade control circuit, comprising: a timer circuit, a pull-up resistor, and a switching circuit. The power supply and reset terminals of the timer circuit are connected to the output terminals of the motherboard. The input terminal of the timer circuit is connected to the output terminal of the motherboard via the pull-up resistor. The output terminal of the timer circuit is connected to the input terminal of the motherboard via the switching circuit. When the input terminal of the timer circuit reaches a preset voltage, the switching circuit is activated, pulling down the output voltage of the motherboard. Therefore, the automated upgrade control circuit provided in this application, when connected to the motherboard, pulls down the output voltage of the motherboard, achieving the effect of manually pressing and holding the power button. It is simple to operate, quick to use, and suitable for large-scale production scenarios, reducing labor and time costs.

[0050] Based on the above embodiments, as a preferred embodiment, such as... Figure 2 As shown, its automated upgrade control circuit also includes a first capacitor C1. The connection is as follows: the first terminal of the first capacitor C1 is connected to the ground terminal GND of the timer circuit 1 and grounded; the second terminal of the first capacitor C1 is connected to the input terminal TRIG of the timer circuit 1 and the first terminal of the pull-up resistor R. When the automated upgrade control circuit is powered on, the first capacitor C1 can be powered on.

[0051] like Figure 2 As shown, the switching circuit in its automated upgrade control circuit is a MOSFET Q, and the MOSFET Q is also connected to the second capacitor C2 and the diode D. The specific connection relationship is as follows: the anode of the diode D is connected to the output terminal OUT of the timer circuit 1; the cathode of the diode D is connected to the gate of the MOSFET Q; the first terminal of the second capacitor C2 is connected to the drain of the MOSFET Q and the input terminal of the main board 3; the second terminal of the second capacitor C2 is connected to the source of the MOSFET Q and grounded.

[0052] like Figure 2 As shown, its automated upgrade control circuit also includes a charging circuit consisting of a first resistor R1 and a third capacitor C3. The specific connection is as follows: the first end of the first resistor R1 serves as the first end of the charging circuit, connected to the power supply terminal VCC of the timer circuit 1 and the output terminal of the main board 3; the second end of the first resistor R1 is connected to the first end of the third capacitor C3, and together they serve as the second end of the charging circuit, connected to the discharge terminal DISCH and the threshold terminal THRES of the timer circuit 1; the second end of the third capacitor C3 is grounded.

[0053] In addition, to ensure the normal operation of timer circuit 1, it also includes: a fourth capacitor C4; the first end of the fourth capacitor C4 is connected to the access terminal CONT of timer circuit 1; the second end of the fourth capacitor C4 is connected to the second end of the third capacitor C3 and grounded.

[0054] Furthermore, in order to display the current status of the circuit and the motherboard, it can be determined by the color change of signal indicator devices (such as indicator lights).

[0055] In a specific embodiment, in monostable mode, timer circuit 1 is activated by a trigger signal. Specifically, when the voltage at the input terminal TRIG of timer circuit 1 is lower than 1 / 3 of the input voltage (which can be understood as when the input terminal TRIG of timer circuit 1 reaches a preset voltage), the output terminal OUT of timer circuit 1 outputs a high level, driving MOSFET Q to turn on, thereby pulling down the output voltage of motherboard 3. At this time, the signal indicator flashes to indicate that an upgrade is in progress. Simultaneously, the third capacitor C3 begins charging. When the charging voltage of the third capacitor C3 is higher than 2 / 3 of the input voltage, the output terminal OUT of timer circuit 1 outputs a low level, MOSFET Q turns off, and the second capacitor C2 discharges through the discharge terminal DISCH. The upgrade is complete when the signal indicator turns constantly lit.

[0056] The timing of its monostable mode is mainly determined by the first resistor R1 and the third capacitor C3 in the charging circuit. For example, if the resistance of the first resistor R1 is 470KΩ and the capacitance of the third capacitor C3 is 66uF, then the timing time T = 1.1 * resistance * capacitance ≈ 35 seconds, which meets the time required for most motherboard upgrades.

[0057] In other words, this application uses the NE555P chip to design an automated upgrade control circuit or fixture to replace the manual operation of pressing and holding the power button. This automated upgrade control circuit or fixture integrates various motherboard upgrade solutions, eliminating the need to find a button board compatible with the motherboard. When the motherboard is plugged into a USB drive containing the upgrade files and powered on, the automated upgrade control circuit or fixture will automatically trigger the motherboard to enter the upgrade process. Once the upgrade completion conditions are met, the indicator light will start flashing. After 35 seconds, the NE555P chip will stop outputting signals (functionally equivalent to releasing the power button). Wait for the upgrade completion indicator light to remain on.

[0058] It should be noted that the embodiments provided in this application are only one method, and users can set them themselves according to their needs.

[0059] As can be seen, the automated upgrade control circuit provided in this application has a simple, integrated, and low-cost structure, which effectively solves the problems of complex and time-consuming motherboard upgrade processes, significantly improves upgrade speed, and reduces labor costs.

[0060] On the other hand, this application also provides a fixture that includes the aforementioned automated upgrade control circuit and has the same beneficial effects.

[0061] Since the embodiments corresponding to the fixtures are the same as those of the automated upgrade control circuits described above, they will not be described in detail here.
