Remote data acquisition method

Abstract

The invention discloses a remote data acquisition method. The remote data acquisition method comprises the steps that: an application terminal sends an acquisition request to an application server; the application server sends the acquisition request to a safety acquisition server; the safety acquisition server sends an acquisition instruction to a safety acquisition terminal according to the acquisition request; the safety acquisition terminal acquires information on a to-be-acquired information carrier according to the requirement of the acquisition instruction; the safety acquisition terminal returns the acquired information to the safety acquisition server; the safety acquisition server sends the acquired information to the application server; and the application server sends a prompt of acquisition completion to the application terminal, wherein the application terminal is provided with an open operating system, and the safety acquisition terminal and the application terminal are not interconnected, and the safety acquisition server and the application terminal are not interconnected.

Description

technical field [0001] The invention relates to a remote data acquisition method, in particular to a safe remote data acquisition method based on an open operating system. Background technique [0002] Traditional remote data acquisition systems based on open operating systems, such as figure 1 As shown, it generally includes a data collection terminal 101 , an application terminal 102 and an application server (APP) 103 . For example, a computer installed with an open operating system is used as the application terminal 102, a card reader is used as the data acquisition terminal 101, the card reader is connected to the computer, and the computer is connected to the application server 103, wherein the card reader is used to read For example, smart card or magnetic stripe card information, and the computer can enter a user password to ensure that the collected information is transmitted to the application server 103. It should be noted here that, in this application, an "op...

Problems solved by technology

In this way, the development cost is huge

Moreover, if the driver installed by the user does not correspond to it, it cannot be used, which puts forward high requirements on the user's operation level, so that many users refuse to use it because of the complicated operation.

[0014] In addition, in the above-mentioned traditional remote data acquisition system based on an open operating system, many hardware interfaces of application terminals developed by different manufacturers are not uniform, especially when application terminals have different forms, such as vending machines, automatic teller machines, etc. , landline phone, tablet computer, PC or notebook computer, the hardware interface is very different

When the hardware interfaces of the application terminal and the data collection terminal are inconsistent or incompatible, the two cannot be connected, and data collection cannot be realized
