Example one
Fig. 1A is a distributed scanning system according to an embodiment of the present invention, including: a background processing device 100 and a plurality of image capturing apparatuses 200; the image capturing device 200 includes a control module 201, a camera 202, and a wireless communication module 203.
The identification code is arranged on the outer side of the product and is positioned at the fixed position of each product and used for representing the attribute and the state information of the current product; for example, the name of the current product and the production node where the current product is located; in the embodiment of the invention, the identification code comprises a Quick Response (QR) two-dimensional code and/or a Data Matrix two-dimensional code; each image acquisition device 200 of the distributed scanning system is distributed at each production node of the industrial production line and is installed at a fixed position in the corresponding production node, so that when products are transmitted through the rail, each image acquisition device 200 can sequentially acquire an identification code image of each product transmitted in the rail.
The control module 201 is connected to the camera 202 and the wireless communication module 203, and is configured to send the identification code image captured by the camera 202 to the background processing device 100 through the wireless communication module 203, so that the background processing device 100 executes a decoding operation of the identification code based on the identification code image, and sends the identification code image to the field debugging device through the wireless communication module 203, so that the field debugging device executes a calibration operation based on the identification code image. The field debugging device (for example, a mobile terminal device) is configured to display an identification code image captured by the camera 202 in the image capturing apparatus 200 in real time, and an operator observes the real-time identification code image in the field debugging device to determine whether the current image capturing apparatus 200 needs to adjust a capturing pose or a focal length, and when it is determined that the adjustment is needed, the operator manually adjusts the image capturing apparatus 200 to ensure that the camera 202 captures a clear and complete identification code image.
The wireless communication module 203 may include at least one of a WIFI (wireless network) communication unit, a bluetooth communication unit, an infrared communication unit, a cellular communication unit, a zigbee communication unit, and an Internet of Things (IoT) communication unit; taking a WIFI communication unit as an example, corresponding WIFI communication parameters are pre-configured in the WIFI communication unit, and after the control module 201 acquires a calibration instruction sent by the field debugging device through the WIFI communication unit, the identification code image acquired by the camera 202 is sent to the field debugging device through the WIFI communication unit; and the field debugging equipment displays the identification code image in real time through a browser webpage or client software.
The background processing device 100 is configured to perform a decoding operation of the identification code based on the identification code image sent by the image capturing apparatus 200, and feed back a decoding result to the image capturing apparatus 200. After acquiring the image sent by the image acquisition device 200, the background processing device 100 first determines whether the image includes an identification code, and if it is determined that the image does not include the identification code, does not perform any decoding operation, and does not feed back any decoding result to the image acquisition device 200; if the image is confirmed to contain the identification code, identifying the identification code, and comparing the identification result with the pre-stored production information to determine whether the current product conforms to the pre-stored production information; if the result is yes, the decoding is fed back to the image acquisition apparatus 200 to pass, and if the result is not yes, the decoding is fed back to the image acquisition apparatus 200 to fail.
The background processing device 100 includes a background terminal device or a background server, and compared with the industrial scanning device located at the front end, the terminal device and the server are not limited by volume, power and chip size, so the background processing device 100 has the characteristics of high decoding efficiency and high decoding accuracy, and one background processing device 100 can complete the identification code decoding operation of the identification code images acquired by the plurality of image acquisition devices 200 and display the decoding result, compared with the case where the decoding device is arranged in each industrial scanning device at the front end, the hardware cost of the distributed scanning system is greatly reduced; meanwhile, the updating and updating of the decoding program and the addition of the identification code type are only executed in the background processing equipment 100, so that the updating convenience of the decoding program is greatly improved.
Particularly, after the field debugging device completes the calibration operation on the image acquisition device 200, the field debugging device may disconnect the communication connection with the image acquisition device 200, so that the image acquisition device 200 only maintains the communication connection with the background processing device 100 when actually operating, thereby avoiding occupying the communication resources of the image acquisition device 200 and improving the communication efficiency between the image acquisition device 200 and the background processing device 100; the communication connection with the image capturing device 200 may also be continuously maintained, so that an operator continuously observes the identification code image obtained by the image capturing device 200, that is, at this time, when the image capturing device 200 actually runs, the communication connection with the field debugging device and the background processing device 100 may be simultaneously maintained, and then the obtained identification code image is simultaneously sent to the field debugging device and the background processing device 100.
Optionally, in the embodiment of the present invention, the image capturing apparatus 200 further includes a posture adjusting component 204 and/or a focal length adjusting component 205; the control module 201 is connected to the attitude adjusting component 204 and/or the focal length adjusting component 205, and is further configured to adjust a shooting attitude of the camera 202 through the attitude adjusting component 204 and/or adjust a focal length of the camera 202 through the focal length adjusting component 205 in response to acquiring a calibration instruction sent by the field debugging device. The attitude adjusting component 204 is arranged at the bottom of the shell of the image acquisition device 200 and is fixedly connected with the shell, and when a calibration instruction sent by field debugging equipment is acquired, the control module 201 acquires attitude adjusting parameters through analysis, and automatically adjusts the shooting attitude of the camera 202 by controlling the rising, falling or inclination angle of the attitude adjusting component 204; the focal length adjusting assembly 205 is arranged inside the housing and connected to the focal length adjusting knob of the camera 202, and when the control module 201 acquires a calibration instruction sent by the field debugging device, the control module acquires a focal length adjusting parameter through analysis, and drives the focal length adjusting knob to rotate through the focal length adjusting assembly 205, so that the automatic adjustment of the focal length of the camera 202 is realized.
Optionally, in this embodiment of the present invention, the wireless communication module 203 includes a first communication unit and a second communication unit; the first communication unit and the second communication unit have different communication modes; the control module 201 is specifically configured to send the identification code image captured by the camera 202 to the background processing device 100 through the first communication unit, so that the background processing device 100 executes a decoding operation of the identification code based on the identification code image, and send the identification code image to the field debugging device through the second communication unit, so that the field debugging device executes a calibration operation based on the identification code image. The communication between the field debugging equipment and the image acquisition device 200 has short communication distance and low real-time requirement, and even if communication delay exists within a certain time, the calibration operation of the identification code image is still not influenced; the communication between the background processing device 100 and the image capturing apparatus 200 is relatively long in communication distance and relatively high in real-time requirement, and the decoding operation of the identification code image needs to be completed in a relatively short time, so that the production efficiency of the product is ensured, and therefore, the communication between the image capturing apparatus 200 and the field debugging device, and the communication between the image capturing apparatus 200 and the background processing device 100 can be respectively realized in different communication modes according to the communication requirements.
Meanwhile, due to the establishment of the different communication modes, when the image acquisition device 200 establishes communication connection with the field debugging device and the background processing device 100 at the same time, the contention for the same communication resource is avoided, and the two communication connections are ensured to have enough communication resources respectively; for example, the image capturing device 200 may selectively use an ESP32 wireless integrated chip, which not only has the characteristics of low power consumption, low price and strong stability, but also has a 2.4GHz WIFI communication function and a bluetooth communication function, so that the WIFI communication unit is set as a first communication unit, and the bluetooth communication unit is set as a second communication unit, thereby further reducing the hardware design difficulty of the image capturing device 200 while establishing communication connections with the field debugging device and the background processing device 100 in different communication modes.
Optionally, in the embodiment of the present invention, the image capturing apparatus 200 further includes a serial port module 206 and a storage module 207; the serial port module 206 is connected to the control module 201, and configured to acquire configuration parameters sent by the background processing device 100 or the field debugging device; the storage module 207 is connected to the control module 201 and configured to store the configuration parameters. The image acquisition device 200 establishes RS232 serial port communication or RS485 serial port communication with the background processing device 100 or the field debugging device through the serial port module 206 to receive configuration parameters; the configuration parameters include communication parameters required when the wireless communication module 203 establishes communication connection with the background processing device 100 and the field debugging device; the storage module 207 is used for storing the configuration parameters; thereby realizing the configuration, updating and storage of the communication parameters required by the image acquisition device 200; meanwhile, when the corresponding production node operates normally, the image acquisition device 200 may be connected to a power supply through the serial module 206, so as to supply power to the image acquisition device 200.
Optionally, in the embodiment of the present invention, the image capturing apparatus 200 further includes an image processing module 208; the image processing module 208 is connected to the control module 201, and is configured to perform graying processing and data compression processing on the identification code image. Graying, namely converting the acquired identification code image into a black-and-white image so as to avoid stripe distortion and reduce the data volume of the image; and in the data compression processing, the data volume of the image is further reduced by encoding the image data, so that the communication resources occupied by the identification code image during transmission are reduced, and the transmission efficiency of the identification code image is improved.
Optionally, in the embodiment of the present invention, the image capturing apparatus 200 further includes a general input/output interface 209, where the general input/output interface 209 is connected to the transmission track management apparatus and the production alarm apparatus respectively; the control module 201 is connected to the general input/output interface 209, and is further configured to send a decoding passing identifier to the transmission track management device in response to obtaining a decoding result fed back by the background processing device 100, so that the transmission track management device drives the current product to move through the transmission track, or send a decoding failing identifier to the production alarm device, so as to send an alarm prompt through the production alarm device.
Specifically, when the image acquisition device 200 acquires the decoding result fed back by the background processing device 100, if the decoding result is that the decoding is passed, it indicates that the current product meets the production requirement of the current production node, a decoding pass identifier is sent to the transmission track management device through a General-purpose input/output (GPIO) interface 209, and the transmission track management module drives the current product to move through the transmission track based on the identifier based on the decoding pass identifier, so that the identifier of the next product appears in the shot picture of the camera 202 of the current image acquisition device 200; if the decoding result is decoding failure, the current product is not in line with the production requirement of the current production node, and a decoding failure identifier is sent to the production alarm device through the universal input/output interface 209, so that the production alarm device sends an alarm prompt to prompt an operator that an unqualified product exists, and the missing detection phenomenon of the unqualified product is avoided.
Optionally, in the embodiment of the present invention, the image capturing apparatus 200 further includes a voltage detecting module 210 and a switching power supply 211; the voltage detection module 210 is connected to the control module 201 and the power supply, and is configured to provide a power detection voltage to the control module 201; the switching power supply 211 is connected to the control module 201 and the power supply, and is configured to supply power to the control module 201; the control module 201 is further configured to send a power-off signal to the background processing device 100 through the wireless communication module 203 when the power detection voltage cannot be obtained. The voltage detection module 210 may specifically include a voltage reduction resistor, a pull-up resistor, a rectification unit, a current limiting resistor, an optical unit, and other components, one end of which is connected to a power supply, for example, a 220V or 380V power supply, and the other end of which is connected to the control module 201; the voltage detection module 210 converts the power supply voltage into a power supply detection voltage suitable for the image capturing apparatus 200, for example, a voltage of 3.3V, and provides the power supply detection voltage to the control module 201; the power detection voltage is used for determining whether the power supply is powered off, and when the power supply is powered off, the voltage detection module 210 cannot provide the power detection voltage to the control module 201; when the power supply is not powered off, the voltage detection module 210 continuously provides the power detection voltage to the control module 201.
The input of the Switch Mode Power Supply (SMPS) 211 is the Power Supply, and the output is a dc Power Supply, for example, a 12V dc Power Supply, which is used to Supply Power to the control module 201 and each function module connected to the control module 201; when the power supply is powered off, the switching power supply 211 is not immediately in a non-power state, and needs to continuously discharge for a period of time, usually 2 seconds to 5 seconds, and during the continuous discharge period, the power supply can continue to supply power to the control module 201 and other functional modules through the power released by the switching power supply 211; during the continuous discharge period of the switching power supply 211, the control module 201 cannot acquire the power detection voltage sent by the voltage detection module 210, and then sends a power-off signal to the background processing device 100 through the wireless communication module 203, so as to implement power-off monitoring and reporting of the image acquisition device 200.
