Problems solved by technology

[0004] One is to send operation and maintenance personnel to the site, connect the emergency broadcasting equipment to the operation and maintenance computer through a serial port or a network cable, and then let the developers in the office log in to the operation and maintenance computer through remote desktop software (such as Sunflower) to troubleshoot. Although there is no need to care about the network failure of the emergency broadcasting equipment, it takes considerable energy and time to send operation and maintenance personnel on business trips
[0005] The second is to allow the emergency broadcasting device to remotely transmit some printouts (equipment operation logs) to the background server through the network for custom interaction, but which printouts and interactive behaviors can be executed need to be written in advance into the software of the emergency broadcasting device, flexibility Poor, especially difficult for OS-level interactions

Embodiment 1

[0048] Embodiment 1 provides a method for remote maintenance of emergency broadcasting equipment based on SSH, including the following steps:

[0049] Step S10, installing lightweight SSH software on the emergency broadcasting device;

[0050] Step S20, the emergency broadcasting device establishes a heartbeat connection with the public network server;

[0051] Step S30, generate a pair of public key and private key through SSH software, and send the public key to the public network server;

[0052]Step S40, based on the maintenance request sent by the maintenance computer, the public network server authenticates the corresponding emergency broadcasting device through the public key;

[0053] Step S50, the public network server establishes an SSH reverse tunnel with the emergency broadcasting equipment;

[0054] Step S60, the maintenance computer remotely maintains the emergency broadcasting equipment through the SSH reverse tunnel.

[0055] The present invention is based o...

Embodiment 2

[0076] Embodiment 2 provides a remote maintenance device for emergency broadcasting equipment based on SSH, including a memory, a processor, and a computer program stored on the memory and operable on the processor. When the processor executes the computer program, it can implement the method in Embodiment 1. Either implementation.

[0077] Since the electronic device introduced in this embodiment is the device used to implement the method in Embodiment 1 of this application, based on the method described in Embodiment 1 of this application, those skilled in the art can understand the electronic device of this embodiment. Specific implementation methods and various variations thereof, so how the electronic device implements the method in the embodiment of the present application will not be described in detail here. As long as a person skilled in the art implements the equipment used by the method in the embodiment of the present application, it all belongs to the protection s...

Embodiment 4

[0079] Embodiment 4 provides an SSH-based remote maintenance medium for emergency broadcast equipment, on which a computer program is stored. When the computer program is executed by a processor, any implementation manner in Embodiment 1 can be implemented.

[0080] In summary, the advantages of the present invention are:

[0081] 1. By installing the dbclient program and the dropbear program on the emergency broadcast equipment running the Linux operating system, an SSH reverse tunnel can be established between the public network server and the emergency broadcast equipment, so that the maintenance computer can communicate with the designated port of the public network server through the SSH protocol After the login request is sent, the login request can be transparently transmitted to the emergency broadcast device by the SSH reverse tunnel. After the login is successful, the emergency broadcast device can be remotely maintained by using the linux command. During the maintena...

Abstract

The invention provides an SSH-based emergency broadcast equipment remote maintenance method, equipment and a medium in the technical field of emergency broadcast. The method comprises the following steps: step S10, installing SSH software on emergency broadcast equipment; step S20, the emergency broadcast equipment establishes heartbeat connection with the public network server; step S30, generating a pair of public key and private key through SSH software, and sending the public key to a public network server; step S40, the public network server performs identity verification on the corresponding emergency broadcast equipment through the public key based on a maintenance request sent by the maintenance computer; step S50, the public network server and the emergency broadcast equipment establish an SSH reverse tunnel; and step S60, the maintenance computer performs remote maintenance on the emergency broadcast equipment through the SSH reverse tunnel. The method has the advantage that the convenience and flexibility of maintenance of the emergency broadcast equipment are greatly improved.

Description

technical field [0001] The invention relates to the technical field of emergency broadcasting, in particular to an SSH-based remote maintenance method, device and medium for emergency broadcasting equipment. Background technique [0002] Emergency broadcasting equipment has the characteristics of being widely distributed. It is usually located in various villages in a certain area. It basically uses the Linux system to maintain communication with the broadcasting platform with the help of wireless networks or network cables, and broadcast tasks at any time. As an emergency broadcasting device operating on an outdoor site, it is always inevitable that various unpredictable failures will occur, and it needs to be maintained (debugged). [0003] For the maintenance of emergency broadcasting equipment, there are traditionally the following two methods: [0004] One is to send operation and maintenance personnel to the site, connect the emergency broadcasting equipment to the op...
