Data acquisition method and mobile terminal

Abstract

The invention discloses a data acquisition method and a mobile terminal. The data acquisition method comprises the following steps: the mobile terminal receives first trigger information used for indicating the start of recording, distributes a data storage buffer zone with preset dimension and records the current start time; the mobile terminal receives the data information of an intelligent card, which is sent by external equipment through an audio interface and acquired by the external equipment, and stores the data information of the intelligent card in the data storage buffer zone; the mobile terminal receives second trigger information used for indicating the termination of the recording and records the current termination time; and the mobile terminal acquires the corresponding data information from the data storage buffer zone according to the termination time and the start time and processes the data information. The mobile terminal comprises a first processing module, a second processing module, a third processing module and a fourth processing module which are used for realizing all the steps respectively. According to the invention, the termination time recorded by the mobile terminal can be regulated correspondingly according to the load progress of the external equipment, thereby ensuring the integrity and the accuracy of data received by the mobile terminal and improving the processing efficiency of the mobile terminal to the data.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a data acquisition method and a mobile terminal. Background technique [0002] With the development of data communication technology, the implementation methods of human-computer interaction and data interaction methods are constantly updated and developed, and there are various types of application scenarios. At present, it is possible to connect the card swiping device with the audio interface of the mobile terminal, transmit the data information of the smart card user obtained by the card swiping device to the mobile terminal through the audio interface, and use the mobile terminal to connect to the wireless communication network for data communication with the remote device . Correspondingly, when the mobile terminal receives the data information sent to it by the card swiping device, it needs to pre-set a data storage buffer inside it to ensure normal data transmission. ...

AI Technical Summary

Problems solved by technology

When the buffer is set too small, for example, it is set to 4 seconds, and the time spent by the user’s card swiping operation exceeds the time limit of the buffer, the mobile terminal will miss information when receiving data, resulting in incomplete received data; when the buffer The area setting is too large, for example, it is set to 30 seconds, and the user swipes the card very quickly, and the time taken is much shorter than the time limit of the buffer, and the buffer cannot end the recording of data in advance, and must run to the set buffer After the user completes the card swiping operation, he still needs to wait for the mobile terminal to complete the remaining time limited by the buffer zone before performing subsequent operations. In addition, when performing data processing, the mobile terminal needs to process the data in the entire buffer zone. Analysis, and because some unnecessary invalid data is stored in it, it will reduce the efficiency of mobile terminal data processing

To sum up, in the prior art, the mobile terminal uses the preset buffer to receive data, which has the problems of low data reception accuracy and low data processing efficiency.
