The voltage of 1 is high level, and the general-purpose input/output pin GP101 outputs a shutdown voltage of 〇V to the voltage input point P2 according to the high level signal, thereby turning off the bipolar official Q3. When the user releases the convex hull button 21, as described above, the transistor Q2 is turned off, and the gate G and the source S of the MOS transistor Q4 are disconnected due to no voltage difference, and the voltage input terminal VIN of the central processing unit 6〇 is The power-on voltage of the +5V is not received and the control electronics 1 is turned off. When the user presses the convex hull button 21 again and again, as described above, the general-purpose input/output pin GPIOO of the central processing unit 60 detects that the voltage of the voltage detection point P1 is once again high level, general-purpose input/output. The pin GPI01 outputs a 3.3V starting voltage to the voltage input point p2 according to the same level nickname, thereby causing the electronic device 100 to enter the power-on state. [0019] The charging delay circuit 40 includes a capacitor C2 100100148 Form No. A0101 The negative pole of the capacitor C2 is grounded. Page 9 / Total 20 pages 1002000244-0 201230512 The positive pole is connected to the collector c of the triode via a resistor {? BaR9, 11 () is connected to the negative electrode. The connection node between the positive electrode of the red 2 and the power is constituted by a voltage detecting point p3, which is the voltage output terminal of the charging delay circuit 40. [0021] The restart control circuit 50 includes a fifth element Q5. In the present embodiment, the fifth switch element is repaired with a _3 tube. The voltage G of the gate G of the tube and the charge delay circuit 4〇 The connection source is grounded, the drain D is connected to a power supply terminal vcc through a pull-up resistor R11, and the connection node between the drain 1) and the resistor R11 constitutes a voltage output point p4, and the voltage output point P4 and The reset pin RESET of the central processing unit 60 is connected and grounded through the capacitor C3 or the Zener diode D1. When the reset pin rESEt is low level, the central processing unit 60 controls the electronic device 100 to restart the system. The charging delay circuit 4 The specific working process of the restart control circuit 50 is as follows: when the user presses the convex hull button 21, as described above, the transistor Q1 is turned on, and the capacitor C2 is connected to the standby power supply terminal VEXT through the resistor R9 and the turned-on transistor Q1. And charging, when the user presses the convex sag button 2 达到 for a preset time, after the voltage of the voltage detecting point P3 reaches a preset value, the MOS transistor Q5 is turned on, and the voltage output point p4 is connected through the turned-on MOS tube. To the ground At a low level, at this time, the re-set pin RESET of the central processing unit 60 is connected to the voltage output point P4 to obtain a low-level signal. The central processing unit 60 controls the electronic device 1 to restart the system. When the user releases After the convex hull button 21, the identification pin id is disconnected from the ground pin GND. Therefore, the transistor Q1 is turned off, and the capacitor C2 of the charging delay circuit 40 is discharged through the resistors R9 and R10, so that the voltage of the voltage detecting point P3 is lowered, resulting in a decrease in voltage of the voltage detecting point P3.
