Description

Method and system for remotely accessing built-in page of terminal equipment
Technical Field
The disclosure relates to the technical field of communication control, in particular to a method and a system for remotely accessing a built-in page of terminal equipment.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
In order to facilitate parameter configuration of terminal equipment of the internet of things such as a serial port server, PLCNET cloud gateways, RTU (Remote Terminal Unit, remote measurement and control terminal), DTU (DATA TRANSFER unit, data transmission terminal) and the like, most of the terminal equipment can integrate built-in pages, and the user can conveniently configure the parameters of the terminal equipment due to the built-in pages. But these terminal equipment built-in pages can only be accessed in the local area network at present, i.e. the IP of the user's configuration equipment (such as a computer, etc.) and the IP of the terminal equipment must be in the same network segment. Because the default IP of the terminal device when leaving the factory is not necessarily in the same network segment with the IP of the user, the client cannot directly access the built-in page of the terminal device to perform parameter configuration, so that the client is very inconvenient to configure the terminal device. In addition, the local area network has a distance limitation, and if the distance between the user and the terminal equipment is long or the use environment of the terminal equipment is bad, the configuration of the parameters of the terminal equipment is very inconvenient.
There are two methods that are currently more commonly used to solve the problem of cross-segment configuration: the first method is realized by broadcasting configuration instructions in a UDP broadcast mode, the configuration is completed after equipment in a local area network receives the broadcast instructions, a state information cross-network section transmission method (publication number CN 107682165A) and a cross-network section equipment searching and communication method (publication number CN 107888711A) patent application in an electric power automation system are both realized by adopting the method, and the method has the defects that broadcast storm is caused under the condition that the configuration instructions are relatively large, the network environment is influenced, the dependence on configuration software is not flexible enough, and the UDP is easy to lose packets to cause high configuration failure rate. Secondly, IP configuration instructions are broadcast through UDP, different network segment equipment IPs in the same local area network are modified into the same network segment, then equipment is configured through TCP or HTTP, and the configuration method is adopted by a quick search connection method (publication number CN 104796484A) and a network IP address automatic allocation method (publication number CN 106506720A) based on a display screen control system, but the method has the defect that the target equipment IP needs to be temporarily changed, and the normal network function of the target equipment can be influenced in the configuration process.
