Description
Technical Field
The invention mainly relates to the technical field of RFID (radio frequency identification devices), in particular to a novel non-inductive bar code radio frequency card data acquisition system and a method thereof.
Background
Radio Frequency Identification (RFID) is a non-contact automatic identification technology, and its basic principle is to utilize the transmission characteristics of Radio Frequency signal and spatial coupling (inductive or electromagnetic coupling) or radar reflection to realize automatic identification of an identified object. The RFID system at least comprises two parts, namely an electronic tag and a reader. The RFID reader (handheld reader) is in wireless communication with the RFID electronic tag through the antenna, and can read or write the tag identification code and the memory data. A typical reader contains a high frequency module (transmitter and receiver), a control unit, and a reader antenna. The RFID reading and writing is roughly divided into a low-frequency reader, a high-frequency reader, an ultrahigh-frequency reader, a double-frequency reader and a 433MHz active reader. The working principle of the RFID is as follows: in the radio frequency identification system, the electronic tag is also called as a radio frequency tag, a transponder and a data carrier; the reader is also called a reading device, a scanner, a communicator, a reader-writer (depending on whether the electronic tag can wirelessly rewrite data). The electronic tag and the reader realize space (non-contact) coupling of radio frequency signals through the coupling element, and realize energy transfer and data exchange in the coupling channel according to the time sequence relation.
There are two types of coupling of radio frequency signals that occur between a reader and an electronic tag:
(1) and (4) inductive coupling. The transformer model realizes coupling through a space high-frequency alternating magnetic field according to an electromagnetic induction law;
(2) electromagnetic backscatter coupling: the radar principle model reflects the emitted electromagnetic waves after the electromagnetic waves touch a target and carries back target information, and the space propagation rule of the electromagnetic waves is based on. The inductive coupling approach is generally suitable for near-field rfid systems operating at medium and low frequencies.
Along with the development of the mobile internet of things, the collection of intelligent data replaces manual recording, and the requirement of people on more convenient and rapid data collection is also obviously improved. However, most of the radio frequency card readers in the market independently and simply utilize a bar code gun and a code reader to acquire one-dimensional code two-dimensional codes and radio frequency card data, and the acquisition needs to use matched software to record the data and is not expensive, so that the problems of complex devices, high cost, poor man-machine interaction, poor user experience and the like exist.
Therefore, the urgent need is that the multi-data acquisition system has stronger functions, is more convenient and faster, better meets the requirements of users, has better man-machine interaction, and directly checks data by using mobile terminals such as a mobile phone or a tablet and the like of a user without a display, thereby being more in line with the development of the technology.

Unless otherwise apparent from the context, or otherwise indicated, like reference numbers in the figures refer to the same structure or operation.
As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.
The relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., are generally based on the orientation or positional relationship shown in the drawings, and are used for convenience of description and simplicity of description only, and in the case of not making a reverse description, these directional terms do not indicate and imply that the device or element being referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the scope of the present application; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of protection of the present application is not to be construed as being limited.

Further, it is required that the present application is understood not only by the actual terms used but also by the meaning of each term lying within.
It will be understood that when an element is referred to as being "on," "connected to," "coupled to" or "contacting" another element, it can be directly on, connected or coupled to, or contacting the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly on," "directly connected to," "directly coupled to" or "directly contacting" another element, there are no intervening elements present. Similarly, when a first component is said to be "in electrical contact with" or "electrically coupled to" a second component, there is an electrical path between the first component and the second component that allows current to flow. The electrical path may include capacitors, coupled inductors, and/or other components that allow current to flow even without direct contact between the conductive components.
Flow charts are used herein to illustrate operations performed by systems according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, various steps may be processed in reverse order or simultaneously. Meanwhile, other operations are added to or removed from these processes.

The raspberry pi system 13 can be connected with a router through wireless WIFI, and a data acquisition program is embedded in a development board of the raspberry pi system 13 and is used for simultaneously acquiring data acquired by the bar code 12 and the card reader 11. The operating system 13 also automatically identifies whether the collected data meets the requirements of the user, and then uploads the data to the server 14, and the user checks data information through the tablet or the mobile phone terminal 15.
And a Raspbian system is installed and operated on the raspberry pi main control module 13. And the module 13 has 4 USB ports, and can support a plurality of USB code readers (one is taken as an example in this case). The raspberry pi serial port is only one, and only one RFID serial port card reader can be supported. The raspberry pi module 13 sends data to the server 14 through wifi connected to a local area network, and the mobile phone or the tablet terminal 15 obtains the data on the server 14 through an installed APK program.
When sending data, the raspberry pi module 13 may choose to send and read only a specific barcode, and the header uses one byte 00 to represent barcode data, and 01 to represent radio frequency card data, so as to distinguish.
When sending data, if the bar code is read from the USB code reader 12, adopting timely reporting to read one reported bar code; if the data is the radio frequency card data read from the RFID card reader 11, the raspberry dispatching system is adopted to actively send an instruction to read, the time can be selected to read once every 500 milliseconds, if the same data is read twice continuously, the same radio frequency card is considered, and the subsequent reading of the same radio frequency card data is not reported. And (3) continuing to report the data of the radio frequency card when the radio frequency card is released (the read data is 0 when the radio frequency card is released), wherein the data of the radio frequency card is read at the last time, and the data of the card is different at two times).
In addition, the invention also makes a network disconnection detection and reconnection mechanism in the aspect of network, when sending data, firstly judges whether the network is connected, if so, sends the data. Under the condition that the network is not communicated, the file is only stored in the local file, and the file is convenient to check. And new threads are created in the program to be continuously connected with the server until the server is connected, and the new data cannot be uploaded to the server.
In a preferred embodiment, the raspberry pi master control module 13 is selected as a 3 rd generation B + model, the barcode reader 12 is a honeywell USB barcode reader, and the RFID card reader 11 is a reader/writer of a common standard that can recognize a tag of a high-frequency 14443A protocol.

first, a folder is created where the program source code can be compiled using GCC. And after generating a corresponding executable program, configuring the address and the port file of the server according to the related instruction document, and configuring the program to start a starting background terminal. And the locally stored data file can be reconstructed in accordance with the file selectable timing tasks. The problem of poor readability caused by too large data of the local data file is avoided.
Secondly, a server program is operated on the server, and the server is ensured to be always in an operating state.
Thirdly, installing the written APK program on the mobile phone or the tablet terminal 15;
fourthly, restarting the raspberry dispatching operating system, and under the condition that the network is smooth, scanning a bar code or a two-dimensional code or a radio frequency card, simultaneously opening a mobile phone or a tablet terminal to run an application program, and checking read data information.
