Description

POS terminal debugging system and method of remote VPN Technical Field The invention relates to the technical field of POS terminal debugging, in particular to a POS terminal debugging system and method of a remote VPN. Background In recent years, with the positive advancement of international strategic layout, the foreign business of the POS machine is steadily expanded. With the deep advancement of the service, the customers in part of the countries find that based on the local service operation requirement, the SIM card carrying the VPN is selected to realize the communication connection between the POS terminal and the platform. The VPN network connection mode can effectively ensure the safety and privacy of terminal transaction data in the transmission process, can adapt to a part of complex network architecture of the country, ensures that a POS terminal can be stably connected to a dedicated service platform of a client, and realizes core functions such as transaction information uploading, terminal state monitoring, service parameter updating and the like. However, an efficient connection with foreign customer VPN platforms cannot be established over conventional network links in the country. Before the POS terminal is formally put into use, the POS terminal must complete the work of key links such as communication adaptation debugging, function compatibility test, transaction flow verification and the like of the customer VPN platform so as to ensure that the terminal equipment can meet the actual service requirements of local customers and ensure the successful development of subsequent transaction services. In view of the fact that the domestic network cannot solve the problem of communication with the customer VPN platform, in order to guarantee the service delivery quality and progress, professional technicians must be arranged to go to foreign customer sites, and omnibearing debugging work is carried out under the environment of local accessible VPN networks until the POS terminal can stably and safely realize data interaction with the customer platform. Disclosure of Invention The invention aims to solve the technical problem of providing a POS terminal debugging system and method for a remote VPN, which realize the development and debugging of the POS terminal for the VPN by realizing a forwarding terminal, a server program and a client program. In a first aspect, the present invention provides a POS terminal debugging system of a remote VPN network, including: The forwarding terminal comprises at least one communication port and is used for forwarding data received by the communication port to the platform through a network connection platform of the VPN SIM card, and receiving data returned by the platform and forwarding the data through the communication port; The client is connected with the forwarding terminal through a communication port, and establishes remote connection with the server, and is used for forwarding the data acquired by the communication port to the server and transmitting the data acquired by the remote connection to the forwarding terminal; the server is connected with the payment terminal to be debugged through the local port, is connected with the client through the remote port, and is used for monitoring the data of the local port and forwarding the data to the client, monitoring the data of the remote port and forwarding the data to the payment terminal.
