Referring to fig. 6, the present embodiment discloses a control method of a remote restart system of a server, where the method of the present embodiment is applied to a main control module, and the present embodiment includes steps S601 to S604:
s601, receiving a restarting instruction of the client.
In the foregoing embodiment, the client is a WEB application, and is carried by the WEB server, and after the client sends a restart instruction, the main control module receives the restart instruction, where the restart instruction includes an address of the target server restart device stored in a database of the WEB server. The receiving mode may be through the internet.
S602, analyzing the restarting instruction to determine the address of the restarting device of the target server.
In this step, the main control module analyzes the received restart instruction to obtain the operation instruction itself and the address of the target server restart device. The analysis comprises links such as protocol decoding and error correction.
S603, establishing connection with the target server restarting device according to the address of the target server restarting device.
Specifically, this step discovers the target server restart device by scanning the address broadcast by the server restart device, and then sends a connection request to establish a connection with the target server restart device.
S604, a control signal is sent to control the target server restarting device to execute restarting operation.
After connection with the target server restarting device is established, namely after communication is established, the main control module sends a control signal to the target server restarting device according to the restarting instruction, wherein the control signal can be an encrypted signal, and the encrypted signal can only be decrypted by the target server restarting device, so that the server restarting device is ensured not to be controlled by other equipment. And the target server restarting device executes restarting operation according to the control signal, namely presses a restarting button of the target server, so that the target server performs restarting.
As a preferred embodiment, the establishing a connection with the target server restarting device according to the address of the target server restarting device specifically includes:
and scanning the Bluetooth slave, judging whether the Bluetooth slave which is the same as the address of the target server restarting device is scanned within a first set time, if so, establishing connection with the Bluetooth slave which is the same as the address of the target server restarting device, and if not, not executing the restarting instruction.
In this embodiment, the target server restarting device may fail for various reasons, and at this time, if the master control module is scanning the failed target server restarting device all the time, other restarting instructions may not be executed, thereby causing the entire remote restarting system to fail. Thus, in order to solve this problem, the present embodiment sets the scan time of the target server restart apparatus, and once the target server restart apparatus is not scanned beyond this time, gives up the task, then executes other restart instructions, or returns to wait for receiving other restart instructions.
Referring to fig. 7, the present embodiment discloses a control method of a remote restart system of a server, which is used for a server restart device, and the present embodiment includes steps S701 to S705:

S703, receiving a connection request sent by the main control module during broadcasting the address of the restarting device of the server.
In this step, if the address broadcasted by the server restarting device is found by the main control module, and the main control module needs the server restarting device to perform the restarting operation, the main control module will send a connection request, and after receiving the connection request, the server restarting device will answer, thereby establishing the communication connection.
S704, after connection is established with the main control module according to the connection request, a control signal sent by the main control module is received.
In this step, the main control module sends a control signal to make the server restart device execute a restart operation after establishing a connection. Here, the control signal may be lost, cannot be received correctly, or is cancelled from being sent, so, in order to avoid the server restarting device waiting indefinitely, power consumption may be set for the server restarting device to set a waiting time, and once the waiting time is overtime and the control signal sent by the main control module is not received correctly, the waiting is abandoned, and the period of alternate dormancy is re-entered.
S705, according to the received control signal, performing a restart operation.
Specifically, referring to fig. 2 and 5, after the control circuit 2 receives the control signal, the motor 1 is started, the motor 1 drives the link assembly to approach the direction of the restart key 17 of the server, and the actuator 3 presses the restart key 17, at this time, the motor 1 is suspended for 4s to complete the shutdown operation of the server. Then, the motor 1 is restarted to move the actuator 3 on the link assembly in a direction away from the restart key 17, and when the actuator 3 is moved to the farthest position from the restart key 17, the motor 1 is suspended for 30s as an interval time of restarting. Finally, the motor 1 is started again, the actuator 3 moves towards the direction of the restarting button 17, the restarting button 17 is pressed again, the button time is 1s, then the motor 1 drives the actuator 3 to stop at the farthest end from the restarting button 17, and the restarting of the server is completed.
As a preferred embodiment, the method further comprises the steps of:
and in a second set time after connection is established with the main control module according to the connection request, the control signal is not received, the server restarting device enters into dormancy, and the dormancy and the broadcasting of the address of the server restarting device are alternately carried out according to a set period.
In this embodiment, a waiting time is set for the server restarting device to receive the control signal. The main purpose is to avoid that the server restarting means is waiting all the time, thus consuming power.
With reference to fig. 8 and 9, the overall control method of the server remote restart system is described in this embodiment. Specifically, the embodiment explains the control flow of the client and the main control module and the control flow of the server restarting device.
