Problems solved by technology

However, when the user quickly presses the button, the time it takes to press the button each time can reach less than 200ms, so that sometimes when the barcode collector is decoding, the user has released the button, and the decoding is terminated, resulting in decoding failure and reduced scanning efficiency. And it is easy to cause the barcode to be missed during continuous scanning

Embodiment Construction

[0027] In order to facilitate a better understanding of the purpose, structure, features, and effects of the present invention, the present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, an example of the data terminal 100 of the present invention is a handheld terminal (PDA). The structure, function and usage of the data terminal 100 will be described in detail below by taking the handheld terminal as an example.

[0029] Such as figure 1 , figure 2 with image 3 As shown, the data terminal 100 includes a protective casing 1 and a data collector 5 , a processor 8 and a memory 9 accommodated in the casing 1 .

[0030] The shell 1 is provided with a plurality of keys 2, at least one of which forms a trigger. A display screen 3 is provided on the front of the housing 1 , and a window 4 is provided on the front face, so that the data collector 5 can collect data through the w...

Abstract

The invention provides a data terminal and a data acquisition method, and the data terminal is characterized in that the data terminal comprises a trigger which is used for triggering to generate a triggering signal and generating a triggering end signal when the triggering is finished; the data collector is used for collecting data; the memory is used for providing a storage space; the processoris used for sequentially storing the trigger signal and the trigger ending signal into a signal queue in real time, calling the signal in the signal queue, and triggering decoding of the data acquiredby the data acquirer when the signal is the trigger signal; when the signal is a trigger ending signal, decoding is ended; wherein the processor preferentially judges the decoding process before calling a signal in a signal queue or judging whether the signal is a trigger ending signal each time, so that the processor continues to call the signal in the signal queue when judging that the signal is not decoded; when decoding is carried out, whether the decoding time reaches a preset threshold value is judged firstly, and then the signals in the signal queue are called continuously.

Description

technical field [0001] The invention relates to a data terminal and a data collection method thereof. Background technique: [0002] When the existing barcode collector scans the barcode, the user presses the button to trigger the scanning, and the main control unit starts decoding at the same time; when the user releases the button, the scanning ends, and the main control unit ends the decoding at the same time. Since the decoding time of the barcode collector is usually about 150ms, for some difficult-to-decode barcodes, the decoding time even needs 200ms. However, when the user quickly presses the button, the time it takes to press the button each time can reach less than 200ms, so that sometimes when the barcode collector is decoding, the user has released the button, and the decoding is terminated, resulting in decoding failure and reduced scanning efficiency. And it is easy to cause the barcode to be missed during continuous scanning. [0003] Aiming at the above pro...
