Technical Field

The invention relates to the technical field of internet data management, in particular to a method for realizing distributed storage of acquisition workstations in an internet scene without public network IP addresses.

Background

The law enforcement recorder management system is a system for uniformly managing videos of the law enforcement recorder and can realize the functions of searching, backing up, counting, playing the videos and the like. With the popularization of law enforcement recorders, the installation requirements of workstations are increased, but many law enforcement agencies do not have a private network and use the internet for office work. In this scenario, to view a video in the law enforcement recorder management system, as shown in fig. 1, each device needs to apply for a public network fixed IP address and coordinate a unit network administrator to perform port mapping on a firewall, and then an internet client can access the video stored in a workstation.

However, the existing public network fixed IP address resources are in short supply, the application process is complicated, the cost is high, heavy network cost is caused to users, and the users need to apply to operators in advance before installation, so that the waiting time is long.

Disclosure of Invention

1. Technical problem to be solved

The invention aims to solve the problems that in the prior art, the fixed IP address resources of a public network are in short supply, the application process is complicated, the cost is high, heavy network cost is caused to a user, and the user needs to apply for an operator in advance before installation.

2. Technical scheme

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a need not public network IP address and realizes gathering workstation distributed storage system under internet scene, includes gathering workstation, server and customer end, the output of gathering workstation and the input both way junction of server, it prevents hot wall to be equipped with between gathering workstation and the server, the output of server and the both way junction of customer end input.

Preferably, the collection workstation is a local area network IP.

Preferably, the firewall is a non-public fixed IP.

Preferably, the server is a public fixed IP.

Preferably, the client is a local area network IP.

The invention also provides a method for realizing the distributed storage of the acquisition workstations in the internet scene without public network IP addresses, which comprises the following steps:

step 1: a workstation in the local area network is provided with an intranet penetration software client, a server is provided with an intranet penetration software server, and a data connection port is opened;

step 2: the workstation is actively connected with the data connection port of the server and requests the server to open the data port B;

and step 3: the server replies that the workstation successfully opens the port and monitors a data port B;

and 4, step 4: the workstation and the server establish a virtual connection between the workstation and the server through the process of the step 1-3;

and 5: the law enforcement recorder management system changes the stored video address into a server IP and a port B;

step 6: the Internet client logs in a law enforcement recorder management system, opens a video playing page and sends a video playing request to a server port B;

and 7: the server end of the intranet transmission software of the server monitors that a port B has a request, and forwards the request to a WEB service port A of a workstation through the virtual connection established before;

and 8: the workstation intranet penetration software client forwards video data sent by the WEB service to a server port B through virtual connection;

and step 9: the server port B forwards the data to the client to finish data transmission, and the client can normally check the video.

Preferably, the workstation maps the own WEB service port a to any unrepeated port B of the server in step 2.

Preferably, in step 4, the request is initiated actively in the lan, so that the firewall can be penetrated.

3. Advantageous effects

Compared with the prior art, the invention has the advantages that:

(1) in the invention, an intranet penetration software client is installed on a law enforcement data acquisition workstation (hereinafter referred to as a workstation), an intranet penetration software server is installed on a server, the workstation is actively connected with the server in a local area network, a self WEB service port is mapped to a designated port on the server, and the internet client can access videos stored by the workstation by accessing the port of the server, thereby realizing the effect of intranet penetration.

(2) In the invention, the workstation establishes a virtual connection with the server in advance through intranet penetration software, the virtual connection plays a role similar to a public network IP receiving client request, when a client plays, the client sends the request to the server instead of a firewall at the workstation side, and the server forwards the request and sends video data to the client.
