Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figure 1 and Figure 2 As shown, the intelligent warehousing and logistics teaching sandbox system provided by the present invention includes: an operation and maintenance deployment platform 1, an intelligent hardware application deployment platform 2, a mobile robot 3, an environmental monitoring station 4, and a classification and storage device 5. The intelligent hardware application deployment platform 2 is connected to the operation and maintenance deployment platform 1, the mobile robot 3, the environmental monitoring station 4, and the classification and storage device 5, respectively.

[0043] (1) The operation and maintenance deployment platform 1 is used to receive operation instructions input by the user based on the current teaching task and transmit them to the smart hardware application deployment platform 2. The operation and maintenance deployment platform 1 is also used to display the operation instructions input by the user.

[0044] In this invention, the operation and maintenance deployment platform 1 is an interface written in Python, used to meet teaching requirements, and overlaid on the smart hardware application deployment platform 2. The smart hardware application deployment platform 2 is indirectly controlled by operating the operation and maintenance deployment platform 1. By configuring IP addresses, protocols, and port numbers, the operation and maintenance deployment platform 1 can detect devices searched by the smart hardware application deployment platform 2, sensor values ​​received by the smart hardware application deployment platform 2, and the current operating status of the devices detected by the smart hardware application deployment platform 2, displaying these information on the operation and maintenance deployment platform 1. Alternatively, corresponding linkage rules set in the smart hardware application deployment platform 2 can be executed by inputting the serial number in the operation and maintenance deployment platform 1.

[0045] (2) The intelligent hardware application deployment platform 2 controls the operation status of the mobile robot 3, the environmental detection station 4 and the classification storage device 5 based on the operation instructions.

[0046] The intelligent hardware application deployment platform 2 is also used to search for and add target devices, and, based on the target devices selected by the user, to individually control each target device or view the current operating status of each target device on the device control interface. The target devices include a mobile robot 3, an environmental monitoring station 4, and a classification and storage device 5.

[0047] The intelligent hardware application deployment platform 2 runs in a mini host to control the operation status of the mobile robot 3, the environmental monitoring station 4, and the classification storage device 5, and to display the parameter values ​​and current operation status of each device.

[0048] The smart hardware application deployment platform 2 is responsible for connecting all devices. Each device sends its status to the smart hardware application deployment platform 2 via wireless communication. Each device has its own ID. By searching for the device ID on the smart hardware application deployment platform 2, the presence of the device ID indicates successful communication. After all communication is successfully established, the devices are added to the smart hardware application deployment platform 2. The added devices are then displayed in the device list. Users can click on the corresponding device to enter the device control interface, control the individual device, or view its status. They can also add linkage rules through linkage management to set trigger conditions for each device for joint control. Furthermore, the instructions written on the smart hardware application deployment platform 2 can be adjusted through the operation and maintenance deployment platform 1.

[0049] (3) The environmental monitoring station 4 is used to store items and monitor environmental data, transmitting the environmental data to the smart hardware application deployment platform 2. The environmental monitoring station 4 is also used to display environmental data.

[0053] The second embedded main control board 402 is connected to the second STC51 microcontroller 401 and the environmental detection sensor, respectively. The second STC51 microcontroller 401 is also connected to the intelligent hardware application deployment platform 2 through the second wireless communication module 403 to receive the operation commands.

[0054] Specifically, the pins of the second STC51 microcontroller 401 are transferred to the second embedded main control board 402, and the data collected by each sensor is transmitted to the second STC51 microcontroller 401 through the second embedded main control board 402.

[0055] Based on the operation instructions, the second embedded main control board 402 controls the environmental detection sensor to detect environmental data, and transmits the environmental data detected by the environmental detection sensor to the intelligent hardware application deployment platform 2 through the second STC51 microcontroller 401 and the second wireless communication module 403.

[0056] In addition, the smart hardware application deployment platform 2 is also used to control the mobile robot 3 or the environmental monitoring station 4 to perform corresponding actions based on environmental data.

[0057] Furthermore, the environmental monitoring station 4 also includes a matrix keyboard and an LCD screen 414. The matrix keyboard is a 4×5 matrix keyboard 413. The LCD screen 414 is connected to the second STC51 microcontroller 401 and is used to display the environmental data. The matrix keyboard is connected to the LCD screen 414 and is used to switch the display pages on the LCD screen 414. The button functions of the matrix keyboard can be customized.

[0058] Furthermore, the environmental monitoring station 4 also includes a warning light. The warning light is a three-color warning light 415. The second embedded main control board 402 is also connected to the warning light, and the second embedded main control board 402 is also used to control the warning light to flash as an alarm when the environmental data exceeds the limit value.

[0059] In addition, the environmental monitoring station 4 also includes a camera 417.

[0060] (4) The mobile robot 3 is used to complete the actions required for the current teaching task under the control of the intelligent hardware application deployment platform 2.

[0061] The actions required for the current teaching task include: self-check, moving to the position of the environmental detection station 4, scanning the items on the environmental detection station 4, picking up the corresponding items from the environmental detection station 4, and placing the picked-up items into the classification storage device 5.

[0062] Specifically, such as Figure 5 and Figure 6 As shown, the mobile robot 3 includes: a first STC51 microcontroller 301, a first embedded main control board 302, a first wireless communication module 303, a Mecanum wheel 304, a magnetic navigation sensor 305, a robotic arm 306, a flexible gripper 307, a gyroscope calibration sensor 308, and a digital scanning module 309.

[0063] The first embedded main control board 302 is connected to the first STC51 microcontroller 301, the Mecanum wheel 304, the magnetic navigation sensor 305, the robotic arm 306, the flexible gripper 307, the gyroscope calibration sensor 308, and the digital scanning module 309. The first STC51 microcontroller 301 is also connected to the intelligent hardware application deployment platform 2 via the first wireless communication module 303 to receive the operation commands. Specifically, pins of the first STC51 microcontroller 301 are transferred to the first embedded main control board 302 to control the operation of other components.

[0064] Among them, the Mecanum wheel 304 is used to control the mobile robot 3 to move to the designated position, the magnetic navigation sensor 305 is used to read the position of the magnetic strip, so that the mobile robot 3 can move along the designated route, the gyroscope calibration sensor 308 is used for the robotic arm 306 to calibrate and return to its position, and the digital scanning module 309 is used to scan the item serial number after the robotic arm 306 reaches the designated position.

[0065] Based on the operation instructions, the first embedded main control board 302 controls the Mecanum wheel 304 and the magnetic navigation sensor 305 to drive the mobile robot 3 to move, controls the robotic arm 306 and the flexible gripper 307 to pick up or drop items, controls the digital scanning module 309 to scan the serial number of the items, and controls the gyroscope calibration sensor 308 to perform self-test.

[0066] In this embodiment, the robotic arm 306 includes a large arm 311 and a small arm 310. When the robotic arm 306 needs to perform a self-test, the first STC51 microcontroller 301 reads the state of the gyroscope calibration sensor 308 by connecting to the first embedded main control board 302, and then controls the large arm 311, small arm 310 and base of the robotic arm 306 to perform a self-test.

[0067] When the flexible gripper 307 needs to grip or drop items, the first STC51 microcontroller 301 is connected to the first embedded main control board 302 to control the opening and closing of the flexible gripper 307.

[0068] When the mobile robot 3 needs to move, the first STC51 microcontroller 301 connects to the first embedded main control board 302 to read the data read by the magnetic navigation sensor 305, and then controls the motor driving the Mecanum wheel 304 to rotate.

[0069] When the digital scanning module 309 needs to scan an item, the first STC51 microcontroller 301 sends instructions to the digital scanning module 309 through the first embedded main control board 302 and receives the data returned by the digital scanning module 309.

[0070] After receiving the operation instructions sent by the intelligent hardware application deployment platform 2, the mobile robot 3 moves to the corresponding shelf 416. After arriving at the shelf 416, it controls the robotic arm 306 to rotate to the corresponding position. Then, it controls the digital scanning module 309 to identify the item. If it is the required item, it controls the flexible gripper 307 to pick up the item. Finally, the mobile robot 3 puts the picked-up item into the classification storage device 5.

[0071] (5) The classification storage device 5 is used to weigh, vacuum and pack the items dropped by the mobile robot 3 under the control of the smart hardware application deployment platform 2.

[0072] Specifically, such as Figure 7 As shown, the classification storage device 5 includes: a third STC51 microcontroller 501, a third embedded main control board 502, a third wireless communication module 503, a housing, a bucket lid 504, a sensing component, a fan 505, and a packaging device 506; the bucket lid 504 is disposed on the housing. The bucket lid 504 is a suspended bucket lid.

[0073] In this embodiment, the bucket lid 504 includes a large lid and a small lid. First, the small lid is opened, and the mobile robot 3 puts the gripped item into the inside of the outer shell. Then, the small lid is closed to perform weighing, ventilation, and packaging operations. Finally, the large lid is opened to take out the packaged item.

[0074] The sensing components include a weighing sensor 507, an infrared sensor 508, an infrared photocell sensor 509, a combustible gas sensor 510, a temperature sensor 511, and a touch sensor 512.

[0075] The weighing sensor 507 is used to weigh the items dropped by the mobile robot 3 to prevent overloading. The infrared sensor 508 is used to detect whether there are items in the surrounding environment; if an item is swept nearby, the lid 504 is opened. The infrared photocell sensor 509 is used to detect whether any items are dropped into the interior of the outer casing. The touch sensor 512 is used to open and close the small lid. The combustible gas sensor 510 is used to detect whether there are combustible gases in the surrounding environment to prevent safety hazards caused by nearby combustible gases. The temperature sensor 511 is used to detect the temperature of the sorting and storage device 5 during operation.

[0076] The third embedded main control board 502 is connected to the third STC51 microcontroller 501, the sensing components, the bucket lid 504, the fan 505, and the packaging device 506. The third STC51 microcontroller 501 is also connected to the intelligent hardware application deployment platform 2 through the third wireless communication module 503 to receive the operation commands.

[0077] The pins of the third STC51 microcontroller 501 are transferred to the third embedded main control board 502, thereby controlling the classification storage device 5 to perform operations such as opening and closing the large and small covers and packing and ventilation. The data collected by each sensor is transmitted to the third STC51 microcontroller 501 through the third embedded main control board 502.

[0078] The third embedded main control board 502 controls the bucket lid 504 to open or close based on the operation command, so that the mobile robot 3 puts the items into the interior of the shell, controls the sensing component to weigh the items put in by the mobile robot 3, controls the fan 505 to ventilate the items put in by the mobile robot 3, and controls the packaging device 506 to package the items put in by the mobile robot 3.

[0079] Furthermore, the sorting and storage device 5 also includes a support plate, a biodegradable waste container, and a power module. The power module is a 12V / 10A charger.

[0080] Furthermore, the environmental monitoring station 4, the mobile robot 3, and the classification and storage device 5 are also used to send their current operating status to the intelligent hardware application deployment platform 2. The intelligent hardware application deployment platform 2 is also used to display the current operating status of the environmental monitoring station 4, the mobile robot 3, and the classification and storage device 5.

[0081] The first wireless communication module 303, the second wireless communication module 403 and the third wireless communication module 503 mentioned above are all 433 modules.

[0082] In this invention, the mobile robot 3, the environmental monitoring station 4, and the sorting and storage device 5 are placed on the same plane. During operation, the mobile robot 3 moves forward from the starting point and first determines whether there is the item required by the operation command on the first shelf 416. If there is, the mobile robot 3 is controlled to pick up the corresponding item and then goes to the sorting and storage device 5 to put the item in. If not, it continues to move forward. When it reaches the back of the environmental monitoring station 4, the digital scanning module 309 detects whether there is the required item on the back of the environmental monitoring station 4. If there is, the mobile robot 3 is controlled to pick up the corresponding item and then goes to the sorting and storage device 5 to put the item in. After putting the item in, the mobile robot 3 returns to the starting point.

[0083] To better understand the technical solution of this invention, the workflow of the intelligent warehousing and logistics teaching sandbox system is described below.

[0084] Step 1: Power on the mobile robot 3, environmental monitoring station 4, and classification storage device 5. Open the smart hardware application deployment platform 2. In the smart hardware application deployment platform 2, configure the same channel number and baud rate as the mobile robot 3, environmental monitoring station 4, and classification storage device 5. Search for each device through 433 wireless communication and add the searched devices to the smart hardware application deployment platform 2.

[0085] Step 2: After establishing a connection via 433, the mobile robot 3, the environmental monitoring station 4, and the classification storage device 5 send their status to the intelligent hardware application deployment platform 2. After receiving the information, the intelligent hardware application deployment platform 2 analyzes the ID number to determine who sent the data and feeds back the information of the received data to the corresponding device.

[0086] Step 3: After searching for and adding devices, the Smart Hardware Application Deployment Platform 2 displays the added devices in the corresponding device management interface, along with relevant information for each device (channel number, ID number, baud rate, protocol type, etc.). This information confirms that all devices have been added to the Smart Hardware Application Deployment Platform 2. Once all devices are added, clicking on the device list in the Smart Hardware Application Deployment Platform 2 will allow you to view the added devices. Clicking on the desired device will take you to the control interface for that individual device, where you can turn actions on / off and view the device's status.

[0087] When operating the mobile robot 3, you can click on it in the device list to enter its control interface. When an action is clicked, the smart hardware application deployment platform 2 sends a data frame via 433 wireless communication. This frame includes a header, trailer, data length, action sequence number, the robot's own ID, and the mobile robot 3's ID. Upon receiving a signal, the mobile robot 3 parses it: first, it analyzes the ID to determine who sent the data. If it identifies the smart hardware application deployment platform 2, it continues parsing, analyzing the ID to determine if the data was sent to itself. If so, it continues further, analyzing the sequence number of the sent action to execute the corresponding action. After successfully receiving the signal, it sends a frame of received signal data to the smart hardware application deployment platform 2. After completing the action, it sends a completion message to the platform.

[0088] When operating the environmental monitoring station 4, you can click on it in the device list to enter its control interface. The control interface of the environmental monitoring station 4 includes multiple switch operations, display of sensor-collected values, and the ability to set upper and lower limits for the sensors. After clicking or setting a limit, the intelligent hardware application deployment platform 2 sends an operation command to the environmental monitoring station 4. Upon receiving the command, the second STC51 microcontroller 401 sends instructions to the corresponding sensors to obtain their currently collected values. After receiving the values ​​returned by the sensors, the second STC51 microcontroller 401 sends the values ​​to the LCD screen 414 for display. Simultaneously, the environmental monitoring station 4 also sends a data frame back to the intelligent hardware application deployment platform 2, sending the data collected by each sensor and its own status. The intelligent hardware application deployment platform 2 updates its control interface upon receiving the returned data.

[0089] When operating the categorized storage device 5, you can click on it in the device list to enter its control interface. When you click a button on the control interface, the smart hardware application deployment platform 2 sends a signal to the categorized storage device 5 via 433 wireless communication. After receiving the signal, the categorized storage device 5 analyzes it to determine if it was sent by the smart hardware application deployment platform 2. If so, it sends a message back to the smart hardware application deployment platform 2 to indicate that it has received the information and sends the information required by the smart hardware application deployment platform 2. After receiving the information, the smart hardware application deployment platform 2 also sends a message back to the categorized storage device 5 to indicate that the reception was successful.

[0090] When operating the maintenance and deployment platform 1, you need to configure your host's IP address and communication method with the smart hardware application deployment platform 2 in the maintenance and deployment platform 1. Within the maintenance and deployment platform 1, you can also search for and control devices. For example, clicking "Search Devices" will only find devices that have already been searched and added on the smart hardware application deployment platform 2. When controlling a single device, you are actually operating the smart hardware application deployment platform 2 through network communication. When clicking "Execute Linkage," you can select the execution sequence number, which must have been pre-programmed in the smart hardware application deployment platform 2. The maintenance and deployment platform 1 simultaneously displays the status of each device and the sensor values. When you change a sensor value in the maintenance and deployment platform 1, it is actually the maintenance and deployment platform 1 controlling the smart hardware application deployment platform 2 to change the sensor value.

[0091] The teaching method of this invention aims to cultivate a rigorous programming mindset in students through state machine programming, thereby training their programming skills.
