[0025] The present invention is further described in detail below in conjunction with the accompanying drawings: See also Figure 1 The present invention discloses a control system for remotely controlling the power on and off of a monitoring unit, characterized in that it comprises a power on and off controller connected between an auxiliary source and a power supply circuit of a monitoring unit; the power on and off controller is signal-connected to a centralized control unit, the centralized control unit is signal-connected to a monitoring unit; the centralized control unit is signal-connected to a remote operation and maintenance platform. The power on and off controller has a built-in relay or a solid-state relay, and is equipped with at least one communication interface for communicating with the centralized control unit. The communication interface is RS485, RS232, USB or Ethernet. The centralized control unit communicates with the operation and maintenance management platform through a network; the centralized control unit directly communicates with the power on and off controller and the monitoring unit through a communication line. The operation and maintenance management platform is provided with a monitoring unit power on and off function module, including power on and power off operation buttons, and a functional area for displaying the status of the monitoring unit. The centralized control unit is signal-connected to a remote operating system for manually issuing instructions for powering on or off the monitoring unit. A security verification module is provided on the communication path between the remote operation and maintenance platform and the centralized control unit, for performing identity authentication and authority verification on the control instructions issued by the remote operation and maintenance platform. The security verification module adopts a multi-factor authentication method, including user name, password, digital certificate and biometric identification, to improve the security of the system. The centralized control unit is equipped with redundant communication lines. When the network communication fails, it can automatically switch to the redundant communication line to ensure that the communication with the operation and maintenance management platform and the power-on and power-off controller and the monitoring unit is not interrupted. The remote operation and maintenance platform is equipped with a timed power-on and power-off module, allowing users to preset the power-on and power-off time to realize the automatic management of the monitoring unit.

[0026] The invention discloses a control system for remotely controlling the power on and off of a monitoring unit. The power on and off controller is connected between an auxiliary source and a power supply circuit of the monitoring unit, and is used to control the power supply state of the monitoring unit according to the received control command; the centralized control unit is connected to the power on and off controller through a communication line, receives the power on and off command from the operation and maintenance management platform, and forwards the command to the power on and off controller for execution, and receives the status feedback of the power on and off controller and the monitoring unit at the same time; the operation and maintenance management platform communicates with the centralized control unit through a network, provides a user interface to receive the power on and off operation command input by the user, and displays the operation state and the online / offline state of the monitoring unit. The scheme remotely sends the power on and off command through the operation and maintenance platform, which is forwarded and processed by the centralized control unit, and finally enables the monitoring unit to perform the power on and off operation. The remote control system can realize the functions of remote monitoring, fault diagnosis, power on and off control, and data collection of the equipment by integrating advanced communication technology and intelligent control algorithms. This method can not only significantly improve maintenance efficiency and reduce maintenance costs, but also enhance customer experience and satisfaction. In this way, we can realize remote restart recovery and self-checking of the equipment to ensure the normal and reliable operation of the system.

[0027] The working principle of the present invention is as follows: Connect the power on and off controller to the power supply circuit of the auxiliary source and the monitoring unit, so that the power supply of the monitoring unit is controlled by the controller; The power on and off controllers are connected to the centralized control unit with a communication line for communication; The centralized control unit communicates with the operation and maintenance management platform using the network; it communicates with the monitoring unit using a communication line; Add the "monitoring unit power on and off" parameter on the operation and maintenance platform. There are two buttons, power on and power off. After clicking the button, the centralized control receives the command and replies to the platform that it has received it. Then the centralized control sends the command to the power on and off controller. After receiving it, the power on and off controller replies that it has received it and disconnects the circuit to achieve the power off effect. After the operation is executed, a signal is returned and reported to the centralized control unit. After receiving it, the centralized control unit reports the execution result to the operation and maintenance platform. When the monitoring unit is powered off, the communication between the centralized control unit and the monitoring unit is disconnected. At this time, the centralized control unit reports to the platform that the monitoring unit is offline; when the monitoring unit is powered on, the communication between the centralized control unit and the monitoring unit is restored. At this time, the centralized control unit reports to the platform that the monitoring unit is online; When the monitoring unit device is abnormal or needs self-test, after-sales maintenance personnel can click the power-off button on the operation and maintenance platform and see that the monitoring unit is offline on the platform; then click the power-on button and see that the monitoring unit is online on the platform, which proves that the restart is complete; If the equipment system does not have an operation and maintenance platform or the operation and maintenance platform is offline, you can also remotely log in to the backend of the centralized control unit and issue power-on and power-off commands to the monitoring unit in the background to perform power-on and power-off operations.

[0028] First, a dedicated power-on and power-off controller is designed. The controller has built-in switching elements such as relays or solid-state relays, which can safely and quickly cut off or connect the power supply circuit of the monitoring unit. This controller must have the ability to seamlessly access the auxiliary source and the power supply circuit of the monitoring unit to ensure that the power status of the monitoring unit can be adjusted as needed under the action of the controller. At the same time, the controller is equipped with a communication interface (such as RS485, RS232 or Ethernet, etc.) to exchange data with the centralized control unit. As the hub of the system, the centralized control unit is responsible for receiving instructions from the operation and maintenance management platform and forwarding these instructions to the corresponding power-on and power-off controller. The centralized control unit must have dual communication capabilities. On the one hand, it maintains a network connection with the operation and maintenance management platform through wired or wireless means, and on the other hand, it establishes a direct communication link with the power-on and power-off controller and the monitoring unit through a communication line. This design ensures the timeliness and accuracy of instruction transmission. On the operation and maintenance management platform, a "monitoring unit power-on and power-off" function module is developed, including two operation buttons: power-on and power-off. Users can initiate power-on and power-off requests by clicking a button, and the platform immediately displays the operation status, including command sending, centralized control unit confirmation, and power-on and power-off controller execution feedback. In addition, the platform must also have the function of real-time monitoring of the online / offline status of the monitoring unit, as well as the function of querying historical operation records, so that operation and maintenance personnel can track and analyze them. In order to deal with abnormal situations or self-inspection requirements that may occur in the monitoring unit, the system allows after-sales maintenance personnel to remotely perform power-on and power-off operations through the operation and maintenance platform, and judge whether the restart is successful by observing the online / offline status changes of the monitoring unit. This mechanism greatly improves maintenance efficiency and equipment stability. Considering that the operation and maintenance platform may be temporarily unavailable due to a malfunction, the system also provides an alternative solution for performing power-on and power-off operations by remotely logging into the background of the centralized control unit. This design ensures effective power management of the monitoring unit even in the most unfavorable circumstances.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
