[0002] At present, many provinces in China are undergoing tax control transformation. Among them, in the tax control transformation and upgrading of large-scale commercial retail enterprises, direct use of tax control cash registers requires enterprises to replace a large number of original POS machines, and even the entire POS system needs to be changed. This is for Retrofits add significant cost and expense

Embodiment Construction
[0020] Before describing the present invention in detail, some terms appearing hereinafter in this text are explained first.
[0021] (1) Metadata: the data that needs to be extracted for analysis, such as amount, time, etc.
[0022] (2) Matching character: the smallest element to match. Can appear in any state as long as the state requires it.
[0023] (3) State: An independent unit of the parsing process, being able to reach a state means that the current data exactly matches the matching character set in that state. The acquisition of key information is to take the state as the unit, and complete the information acquisition while satisfying the state.
[0024] (4) Status character sequence: It is composed of matching characters, and the matching is performed according to their sequence. Only when this sequence is completely matched, the state jump is realized and this state is entered, that is, the state matching is successful.
[0025] (5) State sequence: state matchin...

The invention discloses a bill analysis device and a tax control system. The bill analysis device comprises a data control module, a template configuration module and a metadata analysis module, wherein the data control module is used for receiving original data and storing the received original data in an annular cache storage mode; the template configuration module is used for loading a pre-configured template configuration file and converting the template configuration file into an internal memory template data structure type; and the metadata analysis module is used for conducting data processing on the original data to extract metadata according to the template configuration file loaded by the template configuration module. The bill analysis device and the tax control system have the advantages of being high in identification speed, accuracy and adaptability.
Description
technical field [0001] The invention relates to a bill analysis device and a tax control system. Background technique [0002] At present, many provinces in China are undergoing tax control transformation. Among them, in the tax control transformation and upgrading of large-scale commercial retail enterprises, direct use of tax control cash registers requires enterprises to replace a large number of original POS machines, and even the entire POS system needs to be changed. This is for Retrofitting adds enormous cost and expense. The network tax controller is a tax control device installed between the POS machine and the receipt printer. It does not need to change any POS system. It only needs to print the data through the network tax control device to achieve the purpose of tax control. The network tax controller obtains The tax control metadata in the bill generates a tax control code. This solution is very suitable for the transformation and upgrading of tax control base...
