Description

Method and system for remotely accessing built-in page of terminal equipment
Technical Field
The present disclosure relates to the field of communication control technologies, and in particular, to a method and a system for remotely accessing a built-in page of a terminal device.
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 devices of the internet of things such as a serial server, a PLCNET cloud gateway, an RTU (Remote Terminal Unit), a DTU (Data Transfer Unit) and the like, most of the Terminal devices can be integrated with a built-in page, and the existence of the built-in page greatly facilitates parameter configuration of the Terminal devices by users. However, currently, the built-in pages of these terminal devices can only be accessed in the lan, i.e. the IP of the configuration device (e.g. computer, etc.) of the user and the IP of the terminal device must be in the same network segment. Since the default IP of the terminal device when leaving the factory is not necessarily in the same network segment as the IP of the user, the client cannot directly access the built-in page of the terminal device to perform parameter configuration, and thus it is very inconvenient for the client to configure the terminal device. In addition, the local area network has a distance limitation, and if the user is far away from the terminal device or the use environment of the terminal device is severe, it is very inconvenient to configure the parameters of the terminal device in this case.
Two methods are currently used to solve the problem of cross-network segment configuration: the first method is that a configuration instruction is broadcasted in a UDP (user datagram protocol) broadcasting mode, and the configuration of equipment in a local area network is completed after the equipment receives the broadcast instruction, and the method is realized by adopting the above patent application of a state information cross-network section transmission method (publication number CN107682165A) and a cross-network section equipment searching and communication method (publication number CN107888711A) in the power automation system. The second is that IP configuration instructions are broadcasted through UDP, different network segment equipment IPs in the same local area network are modified into the same network segment, and then the equipment is configured through TCP or HTTP, the patent applications of a fast search connection method (publication number CN104796484A) and a network IP address automatic allocation method (publication number CN106506720A) based on a display screen control system both adopt the configuration method, but the method has the defects that the IP of a target equipment needs to be temporarily modified, and the normal network function of the target equipment is influenced in the configuration process.
