[0056] Example 1

[0057] In modern logistics and transportation, cold storage containers 1 are widely used in the transportation of temperature-controlled goods such as fresh food and medicine. The traditional management method of cold storage containers 1 relies on manual operation, which has problems such as low efficiency, high error rate, and untimely emergency response. Therefore, an automated management and control system is urgently needed to improve management efficiency and ensure the safe and stable operation of cold storage containers 1.

[0058] Based on this, this embodiment provides an automated management and control system for a refrigerated container storage area, which is used to achieve efficient, safe and intelligent management of the refrigerated container 1. Figure 1 , 2 , the control system includes:

[0059] The platform master control system monitors the status of the cold storage box 1, dispatches the robot to perform operations, analyzes data and performs comprehensive management;

[0060] Robot 2 performs specific physical operations, including movement, visual recognition, robot arm operation, temperature and smoke detection, and specifically includes a visual system, a robot arm, a cable clamp, a cable transmission mechanism, a temperature detection system, and a smoke detection system;

[0061] The robot carrying and moving platform includes a horizontal operating mechanism and a vertical operating mechanism, which are used to control the horizontal and vertical movement of the robot;

[0062] The power system manages and monitors the power access to ensure that the refrigerator 1 obtains a stable power supply, which specifically includes a power monitoring module for managing and monitoring the power access to the refrigerator 1;

[0063] Alarm and emergency response systems that detect abnormal conditions, sound alarms, and perform emergency operations;

[0064] The data communication network provides a data transmission channel, ensures real-time data exchange and instruction delivery between systems, and stores historical data.

[0065] System working method: After the system is started, the platform master control system performs self-checking to ensure the normal operation of each module, and the robot system 2 performs self-checking and positioning. After the platform master control system receives a new task request (including the placement and transportation of the refrigerated box 1), the instruction scheduling module generates an operation instruction and sends it to the robot system 2. After receiving the instruction, the robot system 2 is positioned to the specified position through the horizontal operation mechanism 3, and uses the mechanical arm and cable clamp 5 to perform operations such as plugging in and unplugging. The platform master control system monitors the status information (such as temperature, power status, etc.) of the refrigerated box 1 in real time through the monitoring module. The monitoring information and operation results are transmitted in real time through the data communication network, and the data storage module records the relevant information. When it is detected that the information display of the refrigerated box 1 is abnormal, the alarm system issues an alarm, and the emergency processing module performs emergency operations or notifies manual processing according to the preset strategy. Through the collaborative work of the above subsystems and their functional modules, the automated management and control system provided in this embodiment realizes the all-round automated management of the refrigerated box 1, reduces manual operations, improves management efficiency, ensures the safety of the goods in the refrigerated box 1, and ensures the efficient and safe management of the container refrigerated box operation area 1 yard and the ship refrigerated box 1 storage area.

When the robot receives the system operation instruction, the robot can stop at the standard operation position quickly and accurately through the horizontal and vertical movement of the robot carrying platform; Step 3: The robot observes the cables on one side of the cold storage box through the vision system; Step 4: The robot controls the mechanical arm and the cable clamp at the end of the mechanical arm to grab the cable from the cable storage frame in the cold storage box according to the set steps, and transports the cable in the set direction through the cable transmission mechanism. It stops after touching the plug at the end and clamps the plug; Step 5: The robot rotates the mechanical arm to make the plug consistent with the position of the refrigerator-specific socket, and the mechanical arm moves forward to insert the cable plug into the socket corresponding to the platform of the refrigerator-specific socket; Step 6: The refrigerator is connected to the power system through cables, and the refrigerator starts the self-test procedure; Step 7: After the robot waits for the cold box to start, it reads the internal parameter information of the cold box displayed on the cold box display; Step 8: The robot's visual system collects parameter information on the display screen and transmits it to the backend platform master control system for analysis; Step 9: If the parameter is abnormal, the corresponding number will be alarmed; Step 10: The platform master control system analyzes the abnormal parameters and decides whether to remotely control the robot to unplug the plug or dispatch staff to perform on-site maintenance.

8. The method for automatic management and control of a refrigerated container storage area according to claim 7, characterized in that: The temperature detection system and smoke detection system on the robot are used to detect the abnormal increase of the surface temperature of the refrigerator to a dangerous value and the occurrence of dangerous signals such as smoke, triggering the robot to control the mechanical arm to immediately perform the cable pulling operation to prevent dangerous incidents.

9. The method for automatic management and control of a refrigerated container storage area according to claim 7, characterized in that: The following steps are also included: Step 11: When the refrigerated box needs to be transferred, the platform master control system sends the coordinates of the refrigerated box to the robot; Step 12: After receiving the coordinate information, the robot can quickly and accurately stop at the standard operating position through the horizontal and vertical movements of the robot's carrying platform; Step 13: The robot observes the plug corresponding to the platform of the refrigerator dedicated socket through the visual system; Step 14: The robot controls the mechanical arm and the cable clamp at the end of the mechanical arm to unplug the plug and put it into the cold box cable storage frame to recycle the plug cable.
