Therefore, the server is started, which is very convenient, and does not need a manual operation power switch to realize, thereby improving work efficiency. [Embodiment] Referring to FIG. 1, the server restart circuit 100 of the present invention is applied to a server to automatically start the server after the server is powered on. The preferred embodiment of the server restart circuit 100 includes a timing. The device chip U, a voltage input terminal VCC, a diode D1, a transistor Q1, three resistors R1-R3, three capacitors C1-C3 and a boot signal output terminal PS_ON_L. The voltage input terminal VCC is connected to a power supply pin of the server, such as a 9V DC power supply pin (not shown), and the boot signal output terminal PS_ON_L is connected to the servo signal control pin (not shown) of the server. In the embodiment, when the power-on signal control pin of the server receives a low-level signal (such as when grounded), the server is started. This is a conventional technique and will not be specifically described. In the present embodiment, the timer wafer U is a counter wafer of the type NE555DR. The voltage input terminal VCC is connected to the anode of the diode D1. The cathode of the diode D1 is connected to the power supply pin VCC and the reset pin RESET of the timer chip U, and is also connected to the counter wafer U through the resistor R1. Trigger pin TRIG. The trigger chip TRIG of the counter chip U is transmitted through the capacitor C1.

The counter chip (4) is connected to the charge pin DISCH and the threshold pin THRES, and then grounded through the power_ and capacitor C3 in sequence. The turn-out pin 〇υτ of the counter chip U is connected to the base of the transistor Q1 through a resistor. The emitter of the transistor Q1 is grounded, and the collector of the transistor Q1 is connected to the boot signal output terminal PS_〇. N~L. Other Embodiments The transistor Q1 can also be used with other types of electronic switches, as long as the control end of the electronic switch (such as the base of the transistor Q1) is high, the first of the electronic switch The second end (such as the emitter and collector of the transistor Q1) can be turned on. [0009] In operation, if the power is turned off for some reason, the server is turned off, and when the external power source is powered again, the voltage input terminal VCC receives the voltage of 9V, which in turn triggers the timer chip to work 'and outputs a high level signal to the base of the transistor Q1 through the output pin out after a delay time S'. The transistor Q1 is turned on, so The power-on signal output terminal PS-0N-L is grounded. Since the power-on signal output terminal 8-0N-L is connected to the servo signal control pin of the server, it is convenient to start the server, and no manual is required. Work power switch Now, the working efficiency is improved. In the present embodiment, the resistance value of the resistor R2 is 180 ΚΩ, and the capacitance value of the capacitor C3 is 40 "F, and the delay time S can be calculated to be approximately equal to 2 seconds. The delay time S can be adjusted by changing the resistance value of the resistor R2 and the capacitance value of the capacitor C3.
