Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following embodiments and accompanying drawings.
The express cabinet terminal system platform of the embodiment includes a Windows system, an Ubuntu system and an Android system. To implement business functions across platforms, the remote desktop protocol uses the RFB protocol (VNC remote control facility software). The protocol can be applied to all window applications, for example: x11, Windows, and MAC. The terminal system uses a 4G network, and all express cabinet terminal telecommunication cards are set to be connected with a directional network in order to improve the network security of the system. I.e. the terminal may only have access to a certain IP address, and therefore the VNC client cannot directly access the VNC service of the terminal. In the embodiment, a port data forwarding mode is adopted, the network access security is increased by dynamically generating the access port, and the limitation of directional network data transmission is solved.
