the following modules of the invention are described in detail, but the implementation is not exclusive:

1, an image acquisition module:

in the image acquisition module designed by the invention, the core element is a sensor capable of realizing the optical information acquisition function. Commonly used image sensing devices include CMOS devices and CCD devices. In addition, the image acquisition module also comprises a light supplement module and a window module, the light supplement module is composed of a controllable light source element, the window module is composed of a light transmitting sheet and the like, and the specific content of the light supplement module is described in main application materials.

Taking a typical CMOS type digital image sensor as an example, the functional blocks thereof generally include: control registers, communication and control signals and clocks, photosensitive matrices, data output signals, etc.

The control register controls interface data through a transmission bus and sets the functions of the elements;

in the communication, control signals and clock module, the pixel synchronization clock, row/column synchronization signal, frame synchronization signal, sensor clock signal, external clock signal, etc. and timing related information are controlled by the module.

In the photosensitive matrix, the optical signals are converted into electrical signals here, which are stored as digital images represented by pixel points, after various processes.

In the data output signal module, the photosensitive element usually performs some basic image processing operations according to the configuration of the control register. The part also comprises an image format conversion unit and a compression unit, and the converted data is finally output through a data transmission pin.

The working mode of the image acquisition module is as follows:

the central control and processing module in the device provided by the invention can realize the configuration parameters of the registers of the image acquisition element through bus transmission, common bus modes comprise SCCB, I2C and the like, the principle of the SCCB bus is very similar to that of the I2C, and the difference on the configuration mode is not large. The SCCB bus is used as an example to describe the general bus configuration in the device provided by the present invention.

The bus configuration process in the device of the present invention mainly focuses on 3 states: start signal state, stop signal state, and data validity. When SCL (or SIO _ C) is high, SDA (or SIO _ D) has a falling edge, and SCCB begins transmitting (start signal state). When SCL is high, a rising edge occurs in SDA, and SCCB stops transmitting (signal stop state), as shown in fig. 7.

In the data transmission process, when the SCL is at a high level, it is necessary to ensure that the data on the SDA is stable, that is, the level transition on the SDA can only occur when the SCL is at a low level, and the signal of the SDA is collected when the SCL is at a high level, so that the validity of the bus transmission data can be confirmed in the above situation.

It should be noted that different types of bus communication modes may have certain differences in operation details, but the basic principle is consistent, different bus modes need to be configured according to actual hardware conditions and requirements of specific devices, and are implemented by default bus configuration or analog bus configuration, and selection of an appropriate bus mode may make communication of each element in a device system more efficient.

According to the foregoing, the data acquisition process of the image acquisition module in the apparatus of the present invention is substantially as follows:

(1) writing initialization configuration into a register of the image sensor by using a bus clock line and a bus data line pin through a bus protocol;

(2) after initialization is completed, the image sensor outputs image data by using a time sequence of a specific image format;

(3) as the image sensor continues to output image data in a timing sequence of a specific image format, the image sensor transfers the image data to the data storage area through its clock signal line and data signal line;

(4) when the image sensor finishes outputting one frame of data, the sensor can generate an identification signal which indicates that one frame of image is completely output

(5) After the central controller detects the signal, it can know that the image data of one frame is stored in the storage area, and at the moment, it can output the corresponding control signal to prevent the formed image data from being covered by new data or wasting storage space.

(6) The central controller reads out the whole frame of image data of the storage area. During this time, the image sensor continues to output the image data it has acquired, but since a complete image of a frame has been acquired, the data does not need to be stored in the storage area.

(7) After the central controller reads the image data of the whole frame, the writing authority of the image sensor to the data storage area can be restored, and the process can be repeated according to the operation requirement.

2. The central control and processing module:

in the equipment provided by the invention, the central processing and control module is a control and processing center of the equipment and is responsible for activating key functions of each module component, calling data, executing a program algorithm, calculating a number signature result and the like. The equipment provided by the invention is embedded equipment, and a core chip applied by a central processing and control module of the equipment can be composed of chips such as a single chip Microcomputer (MCU) or a Digital Signal Processor (DSP) chip or a Central Processing Unit (CPU) chip similar to the MCU chip in principle. Theoretically, the bit structure of the core processor can be 8 bits, 16 bits, 32 bits, 64 bits, and a higher processing bit number generally means higher processing performance and potential for memory performance. The dominant frequency of the core processor may be different from KHZ level to GHZ level, and a higher dominant frequency means a higher operation control speed. In view of the field of use of the invention, main processor frequencies above 100MHZ and processing bits above 32 bits are suitable.

Taking a 32-bit MCU processor as an example, when a central control and processing module applied by the device provided by the invention adopts a 32-bit MCU processor chip, the basic interface structure layout of the module is as follows: a power supply interface, a crystal oscillator interface, a program downloading interface, a BOOT interface, a reset interface and a GPIO (General-purpose input/output) interface. The central control and processing module can be divided into a kernel part and a kernel peripheral part, the kernel part mainly refers to the MCU processor, the kernel peripheral part can be provided with an external crystal vibration source, an external power supply, a voltage stabilizing circuit, a downloading circuit and the like according to specific conditions, and the kernel part and the kernel peripheral part jointly form the central control and processing module main body. When the selected main processor is other digit or main frequency, the layout principle of the central control and processing module is basically unchanged.

In the work flow, the central control and processing module is used as a main control module of the whole equipment, and the functions of control and processing are realized according to the scheduled work according to the established program. After the power supply is started, the central control and processing module activates all related modules according to the process, controls image acquisition, controls data transmission and storage, processes acquired data, calculates the number of the tags and displays the number in the display module.

3. Operating the memory module:

the equipment system provided by the invention needs enough running memory space to dynamically process data such as variables formed in the running process of the program in working. In an embedded device, a Static Random Access Memory (SRAM) is a component that is commonly used to store data generated when a program is run, such as a dynamic variable. Generally, the SRAM in the cpu/controller chip is called "RAM", and if one SRAM is externally provided, the operation memory of the device may be increased. The SRAM has the characteristics of quick access and direct address selection, but power-fail data is lost, so the SRAM is suitable for being used as a dynamic variable memory for program operation and is not suitable for storing data needing to be stored.

The device provided by the invention needs to process the image data in real time during operation, so the requirement of operating the memory is higher than that of a common embedded device.

If a central processing/controller element with higher performance and higher cost is used, because the chip can be internally and automatically integrated with enough on-chip SRAM space, the dynamic variable storage task in the working process of the equipment can be completed by the on-chip SRAM without additionally operating a memory module. Therefore, if the performance of the central processing unit is enough to maintain the self-running of the program, the running memory module does not need to be added.

If the performance of the used central processing unit/controller is weak and the built-in on-chip SRAM of the central processing unit/controller cannot be sufficient for operating the memory, the operating memory module provided by the invention needs to be applied. The operation memory module can be composed of SRAM, SDRAM and other memory elements with operation memory characteristics, and addressing and data transmission between elements are carried out through proper communication protocols. The structures and interface forms of the memory elements and communication modes of different peripheral operation may be different, but the basic working principles are communicated.

In the schematic diagram shown in fig. 8, VCC is an operating power supply, GND is a ground terminal, D1-Dn are data IO terminals, the specific values are different in different memory devices, the number of data IO terminals is greater than or equal to 1, and n is used herein for the generality of the present invention. C1-Cn are control interfaces through which the central controller can configure the functions of the connected elements. The number of control interfaces, here denoted by n, varies for different types of components. A1-An are address decoding interfaces, through which the fast addressing of the central controller is realized. The number of address decoding interfaces differs for different types of elements, here denoted by n.

The program storage module provided by the invention is expanded on the basic structure of the peripheral storage element, and a filter circuit, a pull-up resistor and the like are added, so that the element works more stably. For external observation, a typical IO interface form of the program storage module according to the present invention is shown in fig. 1.

4. A program storage module:

in the device system provided by the invention, enough storage space which is not lost when power is off is needed to store the algorithm program in the working process, and in the embedded device system, the commonly used storage modules for storing the program content comprise an on-chip flash, an off-chip flash, an EEPROM, an SD card and the like.

In the equipment system provided by the invention, the used central controller can select various processors, and the operating performance and the storage performance of the processors of different manufacturers and different models are different. If a central processing/controller element with higher performance and higher cost is used, because the chip can be internally and automatically integrated with enough on-chip data storage space, the data storage task in the working process of the equipment can be completed by the on-chip storage unit without additionally arranging a program storage module. Therefore, if the performance of the central processing unit is enough to maintain the self-running of the program, the program storage module does not need to be added.

If the performance of the used central processing unit/controller is weak and the on-chip memory unit of the central processing unit/controller is not enough for program storage and operation, the program storage module provided by the invention needs to be applied. The program storage module of the invention can be composed of peripheral data storage elements such as flash memories, EEPROMs, SD cards and the like which are not lost when power is off, and data transmission among the elements is carried out through a proper bus mode or a communication protocol. The structures and interface forms of different peripheral memory elements and communication modes may be different, but the basic working principles are communicated. As shown in fig. 9.

The program storage module provided by the invention is expanded on the basic structure of the peripheral storage element, and a filter circuit, a pull-up resistor and the like are added, so that the element works more stably. For external observation, the typical IO interface form of the program storage module according to the present invention is shown in fig. 1:

VCC is a working power supply, GND is a ground terminal, D1-Dn are data IO terminals, specific values are different in different memory devices, the number of the data IO terminals is greater than or equal to 1, and the number is represented by n for the universality without limiting the invention. C1-Cn are control interfaces through which the central controller can configure the functions of the connected elements. The number of control interfaces, here denoted by n, varies for different types of components.

5. An interaction module:

the counting starting button and the parameter adjusting button are collectively called as an interactive module, and the interactive module has the main function of transmitting manual instructions of an operator to the central control and processing module so as to further control the running state of the equipment. Through the interaction module, an operator can achieve the purposes of starting a program, debugging working parameters, closing the program, changing a display mode and the like. The physical form of the interaction module can be a solid key layout, or a touch screen interaction layout or a pulley and knob layout, and the like, and the different layouts have certain differences in expression forms, but the basic principles are communicated. The basic principle is to operate the interaction module, realize the mapping from the physical space to the interface space, and further to the program flow. Different physical space touch controls are realized, different interface level states are realized, and then the central control and processing module is activated to execute different operations.

In the use of the device provided by the invention, an operator can realize the related functions of the device by operating the interaction module. As shown in fig. 10.

6. A display module:

the display module has the main function of displaying the working state and the number result of the equipment to an operator through a display screen. The display module can be composed of various typical display screen elements, including various LED, LCD, nixie tube and other devices capable of displaying information. The display module is connected with the central control and processing module, and the main interfaces are a data IO interface, a control interface, a power supply interface and a ground wire interface.

When the device provided by the invention works, if the working state and the tag counting result need to be displayed, the central control and processing module configures the display module through the connected port and transmits related data, as shown in fig. 11.

7. A power supply module:

the main function of the power supply module is to provide power supply for the equipment. Under normal conditions, in order to keep the device stable and operating for a long time, the external voltage of the device may be 5 vdc, or may be 9 vdc, or may be 12 vdc, or other voltages. In different specific component models and specific working environments, the total external power supply voltage of the applicable equipment may be different, the rated voltage directly connected to the central control and processing module through the power supply module may also be different (usually 3V-5V, or higher), the specific application condition may be configured according to each component data manual, the basic principle of the work is consistent under different voltage conditions, and there is no obvious difference in hardware layout.

The hardware layout structure of the power module mainly comprises an external power supply and a voltage stabilizing and reducing circuit, and a typical layout structure is shown in fig. 12; fig. 12 illustrates a 5V power supply, and the source power supply forms a stable 3.3V power supply through a voltage stabilizing and reducing circuit, and is directly connected to the central control and processing module, so as to provide a working power supply for the whole device.

In summary, the practical effects of the invention are as follows:

in the design of the equipment for counting the tags, the first reflection of most people starts from the mechanical principle, and the tags are counted by combining an active or passive transmission structure with a certain photoelectric or mechanical technology sensing and counting device. However, in practical practice, it is not easy to find that such a design not only occupies a large space, but also has obvious defects in the aspects of counting speed, accuracy, power consumption, safety, comfort and the like, and it can only be said that such a design only theoretically replaces a part of manual work of an operator, but is not suitable in practical application. For decades, the work of counting sticks has not been well automated substitute products, but the weighing mode is only a 'method without way'. The device provided by the invention develops a new way, bypasses the trap of a counting structure with mechanical transmission, adopts the principle of optical image scanning and is embodied in the form of the device, finds out the unique optical characteristics of the label class objects, and well solves the problem of difficulty in counting labels by means of design and research.

The invention provides a whole set of comprehensive solution based on equipment for the log-signature method, and the existing solution in the market does not have good products which can comprehensively solve the contradictions of efficiency, accuracy, volume, safety, power consumption, reliability, threshold and the like. In general, an invention can only focus on resolving one or a few of the composite conflicts, but not all. The device provided by the invention solves most of contradictions existing in the technical field of digital signatures at one stroke, and has the advantages of high recognition speed, accurate result, flexibility, small size, safety, electricity saving, cleanness, quietness, reliability, durability, rapid application, strong adaptability and low cost.

In the aspect of efficiency, the maximum pain point of a multi-label market, under the ideal condition, the equipment number-label rate of the invention can reach hundreds of times of the manual number-label rate, batch counting can be completed within 1 second, the specific rate is determined by the main frequency of a processor in a host module, if a high-grade processing chip is matched, the counting rate can reach thousands of times of the manual speed, and the revolutionary advantage of the multi-label efficiency is achieved. In other attributes, the recognition accuracy rate is more than 99% in combination with the optimization algorithm used by the invention under an ideal condition; the power consumption of ma milliampere level is lower than that of the mobile phone; the noise is low, and is quieter than manual operation; the electric shock risk is low, and the working voltage is lower than 9V; no decoration cost is caused, and any environment layout is not required to be changed; the threshold is zero, and the user can start the device without any special training; the novel table is small in occupied area and small in size, can replace a common traditional cartridge on a table and can also be placed in a bar counter or a hand, and therefore, any table top space does not need to be additionally occupied; no pollution, convenient cleaning and no dirt.
