Description

Technical Field

[0001] This invention belongs to the field of museum display case technology, specifically relating to a method and system for autonomous movement and display control of intelligent digital display cases for cultural relics and museums. Background Technology

[0002] As core equipment for the protection and display of cultural relics, the functionality, practicality, and operational safety of display cases directly affect the effectiveness of cultural relic protection and the flexibility of exhibitions. With the diversification of museum exhibition formats, the demand for adjusting display case locations and displaying in multiple scenarios is becoming increasingly frequent. The technical limitations of traditional cultural relic display cases are gradually becoming apparent, making it difficult to meet the requirements of efficient operation and refined protection in the modern cultural relic industry.

[0003] In existing technologies, moving display cases mostly relies on manual handling or simple mechanical assistance. This not only requires multiple people to work together, which is time-consuming, labor-intensive, and costly, but also easily leads to collisions between personnel and damage to the display cases due to improper handling during the process, and may even indirectly affect the safety of the cultural relics inside. To avoid damage to cultural relics during the movement, in most cases, the cultural relics must first be removed from the display case, professionally packaged, and transported to a temporary storage environment before being placed back into the adjusted display case. During this process, changes in environmental temperature and humidity, vibration, and other factors can easily cause irreversible damage such as brittleness of paper cultural relics, cracking of wooden artifacts, and fading of textiles, making the transportation of cultural relics extremely risky.

[0004] In response, this application proposes a method and system for autonomous movement and display control based on a cultural relics intelligent digital display cabinet, in order to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a method and system for autonomous movement and display control based on a cultural relics intelligent digital display cabinet, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The autonomous movement and display control method based on the intelligent digital display cabinet for cultural relics includes:

[0008] S1. Open the professional software interface through the host computer and enter the password, or connect the tablet to the wireless WIFI and enter the tablet's dedicated software interface and enter the password. Send a control command containing the IP of the cabinet to be moved and the target backup IP location. The intelligent digital cabinet control device receives and parses the command and generates initial control data.

[0009] S2. The drive control device receives initial control data, collects path data through the lidar autonomous navigation system and obstacle data through the ultrasonic sensor, and the intelligent digital cabinet control device plans the movement path and generates drive signals based on the data.

[0010] S3. Power the bottom drive unit through the backup power supply. The bottom drive unit receives the drive signal and the servo motor drives the two servo motor drive wheels. The differential speed principle is used in conjunction with the auxiliary universal wheels to realize the movement of the display case. When the ultrasonic sensor detects an obstacle, it stops immediately and the initial movement state is obtained.

[0011] S4. When the display case moves to the target backup IP location, the QR code camera reads the target location QR code, and the intelligent digital cabinet control device adjusts the servo motor speed according to the QR code information, calibrates the display case position, completes precise positioning, and obtains the movement positioning result.

[0012] Preferably, in step S1, before the host computer sends the control command, it needs to input the station corresponding to the cabinet to be moved through the IP address selection button, and click the IP address confirmation button again. Only after the intelligent digital cabinet control device confirms that the target backup IP address is empty will it parse the subsequent movement command.

[0013] Preferably, in step S1, the tablet operating terminal adjusts the movement speed of the bottom driving device by setting the movement speed, and sends directional commands by using the up, down, left, and right arrow keys. The directional commands are then parsed into driving signals for the corresponding directions.

[0014] Preferably, in step S2, the intelligent digital cabinet control device and the drive control device communicate via the IP addresses of the master PLC and the slave PLC. The master PLC sends out the drive signal after path planning, and the slave PLC receives and controls the bottom drive device to operate.

[0015] Preferably, in step S3, after the ultrasonic sensor detects an obstacle and stops, and the personnel retreat to a safe position, a start command needs to be sent again through the host computer or tablet operating terminal; if the lidar autonomous navigation system detects an obstacle for more than a set time, it will automatically plan a detour path and continue moving.

[0016] Preferably, in step S4, the calibration accuracy of precise positioning is judged by the position deviation value of the QR code read by the QR code camera. When the deviation value is less than a preset threshold, the servo motor stops driving, and the positioning is determined to be complete.

[0017] Preferably, in step S3, when the servo motor of the bottom drive device drives the wheels to rotate at the same speed, the display case moves straight; when they rotate at different speeds, they turn in conjunction with the auxiliary casters, and the turning angle is controlled by the speed difference of the servo motor.

[0018] Preferably, in step S1, the cabinet to be moved needs to be moved to a temporary backup IP location first. After the intelligent digital cabinet control device confirms that the temporary location is not occupied, it executes the instruction to move to the target backup IP location.

[0019] Another aspect of the present invention is to provide an autonomous movement and display control system based on a cultural heritage intelligent digital display cabinet, comprising:

[0020] Intelligent digital display cabinet system, host computer, tablet operating terminal, bottom drive device, drive control device, intelligent digital cabinet control device, wireless monitoring terminal group and base station;

[0021] The intelligent digital cabinet control device has a built-in PLC programmable control system, which is used to communicate with the host computer, tablet operation terminal, drive control device, wireless monitoring terminal group and base station, receive and parse control commands and environmental data, and output regulation and alarm signals; the wireless monitoring terminal group includes wireless carbon dioxide monitoring terminal, wireless formaldehyde monitoring terminal and wireless volatile organic compound monitoring terminal.

[0022] The wireless carbon dioxide monitoring terminal has a measurement range of 0–2000 ppm and an accuracy of 60 ppm ± 2%.

[0023] The wireless formaldehyde monitoring terminal has a measurement range of 0–10 ppm and a measurement accuracy of 0.02 ppm ± 4%.

[0024] The wireless volatile organic compound monitoring terminal has a measurement range of 0-20 ppm (isobutylene), a resolution of 0.01 ppm, and an accuracy of 0.1 ppm ± 8% of the indicated value. All three types of terminals adopt a safety design guided by cultural relic safety and have dual power supply capabilities of battery and wired power.

[0025] The base station uses the National Radio Regulatory Commission's application-free frequency band and has the capabilities of self-organizing network, periodic heartbeat packets, recording and reporting routing information, link quality detection and data verification. The wireless network gateway is connected to the host computer remotely, with a transmission power ≤22dBm and a communication distance greater than 200 meters for line-of-sight transmission.

[0026] The bottom of the intelligent digital display cabinet system is connected to the bottom drive device, and it has a built-in constant temperature and humidity machine, cooling fan and intermediate relay, which, together with the wireless monitoring terminal group, realizes environmental monitoring and control.

[0027] Preferably, the professional software interface configured on the host computer corresponds to the environmental monitoring software system, which has the functions of setting monitoring points and parameters, professional data analysis, list or graphical display, real-time alarm, and historical data query.

[0028] The environmental monitoring software system can be deployed in a domestically developed information technology environment and provides an interface to connect to the Zhejiang University Cloud Data Center. Before the system goes online, it must undergo penetration testing by a third-party organization and provide a test report. The vulnerability repair rate is 100%.

[0029] Preferably, the drive control device is equipped with a lidar autonomous navigation system, an ultrasonic sensor, and a QR code camera, and is connected to an intelligent digital cabinet control device to receive instructions and collect navigation and positioning data;

[0030] The bottom drive device is equipped with a servo motor, servo motor drive wheels, auxiliary casters and a backup power supply. It is powered by the backup power supply and drives the servo motor drive wheels through the servo motor, and moves the display case in conjunction with the auxiliary casters.

[0031] The tablet operating terminal is equipped with a dedicated tablet software operating interface, movement speed setting, and directional keys, which are used to send movement control commands via wireless WIFI after entering a password.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] (1) This invention supports two modes: remote control via a host computer and local control via a tablet operating terminal. There is no need for manual handling of the display cases. One person can complete the position adjustment of one or more display cases, which greatly saves labor and time costs. The display cases are autonomously navigated by a laser radar autonomous navigation system, obstacle detection by ultrasonic sensors, and precise positioning by a QR code camera. During the movement, they can automatically avoid obstacles, stop, or detour, avoiding the problems of personnel bumping into each other and damage to the display cases caused by traditional manual handling.

[0034] (2) In this invention, exhibits do not need to be removed during movement, reducing irreversible damage caused by environmental changes or operational errors during the transfer and storage of cultural relics. At the same time, the backup power supply ensures stable power supply during the movement process, further reducing the safety risks of cultural relics. Management personnel can remotely adjust the color temperature of the lights, control the opening and closing of cabinet doors and the start and stop of the constant temperature and humidity machine through the host computer or tablet terminal, without having to touch 220V high voltage electricity, completely avoiding the risk of electric shock, and making the operation process safer. Data such as temperature, humidity, and concentration of toxic and harmful gases are synchronized to the host computer and OLED transparent screen in real time, eliminating the need for on-site copying and recording, reducing the on-site workload of management personnel, and improving work efficiency.

[0045] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] Please see Figures 1 to 9 As shown, the autonomous movement and display control method based on the intelligent digital display cabinet for cultural relics includes the following steps:

[0048] Step 1: System Initialization and Communication Establishment

[0049] After the system starts, the PLC programmable control system 50 of the intelligent digital cabinet control device 8 is automatically initialized, and the backup power supply enters standby mode. If a 220V mains power is connected, the mains power will give priority to powering each electrical component, and the backup power supply will be charged through the power monitoring and control system. After charging is completed, the charging circuit will be automatically cut off.

[0050] Remote control mode preparation: After the host computer 1 starts up, it opens the professional software interface 2. The operator enters the password 18 to complete the identity verification. The host computer 1 establishes an IP communication connection with the main station PLC of the intelligent digital cabinet control device 8. The system automatically scans and displays the IP addresses 21 of all intelligent digital display cabinets in the venue and the corresponding system 5, and marks the available spare IP positions 20.

[0051] Tablet control mode preparation: The tablet operation terminal 3 connects to the same network as the PLC programmable control system 50 via wireless WIFI. The operator enters the tablet-specific software operation interface 4, enters the password 24 to complete the verification, and the tablet operation terminal 3 establishes communication with the slave PLC of the drive control device 7. At this time, the movement speed setting 25, the up arrow key 27, the down arrow key 29, the left arrow key 28, and the right arrow key 26 are in an operable state.

[0052] Step 2, Mobile Control Process (Remote Control Mode):

[0053] Command issuance: On the professional software interface 2, the operator selects the IP address 21 corresponding to the intelligent digital display cabinet to be moved and system 5 through the IP address selection button 22. After confirming that the target spare IP position 20 is free, the operator clicks the IP address confirmation button 23 again. The host computer 1 sends a control command containing the moving target address to the main station PLC.

[0054] Path planning: The master PLC forwards the instructions to the corresponding intelligent digital display cabinet and the slave PLC of system 5. The slave PLC drives the control device 7 to start the lidar autonomous navigation system 30 to collect spatial path data of the venue. At the same time, the ultrasonic sensor 31 collects surrounding obstacle data in real time. The two types of data are transmitted synchronously to the PLC programmable control system 50 for fusion processing to plan a collision-free movement path.

[0055] Autonomous movement: The PLC programmable control system 50 sends a drive signal to the bottom drive device 6. The backup power supply provides power to the servo motor 32. The servo motor 32 drives the two servo motor drive wheels 34 to run along the planned path. When the two servo motor drive wheels 34 are at the same speed, the intelligent digital display cabinet and system 5 move straight. When the speeds are different, the auxiliary universal wheels 40 are used to turn.

[0056] Obstacle handling: During the movement, if the ultrasonic sensor 31 detects an obstacle, person or animal, the PLC programmable control system 50 immediately sends a stop signal, the servo motor 32 is powered off, and the intelligent digital display cabinet and system 5 stop moving; if the person retreats to a safe position, the operator can send a restart command through the host computer 1; if the lidar autonomous navigation system 30 monitors obstacles for more than the set time, the PLC automatically replans the detour path and drives the display cabinet to continue moving.

[0057] Precise positioning: When the intelligent digital display cabinet and system 5 move to the vicinity of the target backup IP position 20, the QR code camera 33 starts and reads the QR code of the target position, and feeds back the position deviation data to the PLC programmable control system 50. The system adjusts the speed of the servo motor 32 to calibrate the position of the display cabinet until the deviation value is less than the preset threshold. The servo motor 32 then stops running, completing the precise positioning.

[0058] Step 3, Mobile Control Flow (Tablet Control Mode):

[0059] Parameter setting and command sending: The operator adjusts the movement speed through the movement speed setting 25 on the tablet-specific software operation interface 4, and then sends forward, backward, left and right movement commands through the up arrow key 27, down arrow key 29, left arrow key 28 and right arrow key 26. The commands are transmitted in real time to the slave PLC of the drive control device 7 via the wireless network.

[0060] Drive execution: After receiving the instruction from the slave PLC, it outputs the corresponding drive signal to the bottom drive device 6. The servo motor 32 drives the servo motor drive wheel 34 to rotate according to the instruction. The auxiliary caster wheel 40 cooperates to adjust the movement direction, realizing the manual control movement of the intelligent digital display cabinet and system 5.

[0061] Safety linkage: During the movement, the ultrasonic sensor 31 continuously monitors the surrounding environment. Once an obstacle is detected, the slave PLC immediately cuts off the drive signal of the servo motor 32, and the display case stops moving. After the obstacle is removed, the operator triggers the corresponding direction key again, and the display case resumes movement. The lidar autonomous navigation system 30 synchronously assists in correcting the movement trajectory to avoid deviation.

[0062] Step 4: Precise Environmental Control Process

[0063] Data Acquisition: The temperature and humidity sensor of the intelligent digital cabinet control device 8 collects the temperature and humidity data inside the intelligent digital display cabinet and system 5 in real time through the RS485 Modbus RTU communication protocol. The data is synchronously transmitted to the PLC programmable control system 50 and displayed in real time on the OLED capacitive touch screen.

[0064] Control execution: The PLC programmable control system 50 compares the real-time temperature and humidity data with the preset threshold. If the threshold is exceeded, a start command is sent to the constant temperature and humidity machine, and the constant temperature and humidity machine starts to work, adjusting the temperature and humidity inside the display case. When the temperature and humidity return to the preset range, the PLC programmable control system 50 sends a stop command, and the constant temperature and humidity machine stops.

[0065] Abnormal alarm: If the constant temperature and humidity machine malfunctions (such as failing to reach the set temperature and humidity), the PLC programmable control system 50 will trigger an alarm signal, display the alarm information through the dedicated software interface, and simultaneously send feedback to the host computer 1 to remind the management personnel to handle the situation.

[0066] Heat dissipation control: Temperature and humidity sensor 52 synchronously collects temperature and humidity data of the electrical control box of intelligent digital cabinet control device 8. When the data reaches the set value, PLC programmable control system 50 outputs a signal to activate intermediate relay 43 and start cooling fan 42 to dissipate heat. When the data is lower than the set value, intermediate relay 43 disconnects and cooling fan 42 stops working.

[0067] Step 5, Safety Monitoring Process:

[0068] Toxic and harmful gas monitoring: Toxic and harmful gas sensors collect real-time data on the concentration of gases such as formaldehyde and sulfur dioxide inside the intelligent digital display cabinet and system 5. The data is transmitted to the PLC programmable control system 50 via RS485 Modbus RTU communication protocol. The data is simultaneously displayed on the professional software of the host computer 1 and the OLED capacitive touch screen. When the concentration reaches the alarm set value, the system triggers an audible and visual alarm and displays the alarm content on the toxic and harmful gas monitoring page, reminding the management personnel to take protective measures before opening the cabinet door.

[0069] Security warning: Vibration sensors monitor the external vibration signals of the intelligent digital display cabinet and system 5 in real time. If the vibration signal frequency exceeds the preset safety range due to external impact, earthquake, etc., the PLC programmable control system 50 converts the low-frequency signal into a switch output, the intermediate relay is turned on, and the buzzer starts a combined sound and light alarm. If a single display cabinet alarms, the host computer 1 immediately locks the location of the alarmed display cabinet. If two or more display cabinets alarm at the same time, the system triggers all intelligent display cabinets on site to alarm synchronously, prompting visitors to evacuate.

[0070] Step Six: Digital Interaction Process

[0071] Interface startup: After the intelligent digital display cabinet and system 5 are powered on, the intelligent digital cabinet's OLED transparent screen initializes. On-site management personnel enter the login password to access the user control interface, and visitors can directly operate the system through the OLED transparent screen.

[0072] Equipment control: Administrators can adjust the color temperature of the bullseye lamps through the manual input box for light color temperature on the user control interface or through the light adjustment slider controller. They can control the cabinet door opening and closing in automatic mode via the door open or close button, or manually operate the cabinet door via the manual jog mode. They can control the start and stop of the constant temperature and humidity machine via the switch button. All operations do not require contact with high voltage electricity, reducing safety risks.

[0073] Interactive exhibits: Visitors can touch the buttons on the OLED transparent screen of the smart digital cabinet to activate the rotation and tumbling effects of the 3D models of the exhibits, or play historical introductions of the exhibits; at the same time, they can directly touch the 3D models to rotate, zoom in and out, and achieve a 360° all-round viewing experience, enhancing the interactive experience.

[0074] Step 7, Data Management Process:

[0075] Data storage: The PLC programmable control system 50 automatically stores monitoring data such as temperature and humidity, concentration of toxic and harmful gases, as well as equipment operating status, alarm records, and other information. The stored data supports historical traceability.

[0076] Data viewing and export: Managers can access the historical data screen for temperature, humidity and toxic and harmful gases through the professional software on the host computer 1 to view the monitoring data. They can also export the data to mobile devices by using the historical data browsing button, or view the data change curve through the historical data curve screen to intuitively understand the internal environment of the display case and the operation of the equipment.

[0077] As can be seen from the above, the present invention supports two modes: remote control by the host computer 1 and local control by the tablet operating terminal 3. There is no need for manual handling of the display cases. One person can complete the position adjustment of one or more display cases, which greatly saves labor and time costs.

[0078] The display case uses a LiDAR autonomous navigation system 30 for autonomous navigation, an ultrasonic sensor 31 for obstacle detection, and a QR code camera 33 for precise positioning. During movement, it can automatically avoid obstacles, stop, or detour, thus avoiding the problems of people bumping into each other and damage to the display case caused by traditional manual movement.

[0079] The exhibits do not need to be removed during relocation, reducing irreversible damage caused by environmental changes or operational errors during the transfer and storage of cultural relics. At the same time, the backup power supply ensures stable power supply during the relocation process, further reducing the safety risks to cultural relics.

[0080] Managers can remotely adjust the color temperature of the lights, control the opening and closing of the cabinet doors, and start and stop the constant temperature and humidity machine via the host computer 1 or the tablet terminal 3, without having to touch 220V high voltage electricity, completely avoiding the risk of electric shock and making the operation process safer.

[0081] Data such as temperature, humidity, and concentration of toxic and harmful gases are synchronized in real time to the host computer 1 and the OLED transparent screen, eliminating the need for on-site copying and recording, reducing the workload of management personnel on-site, and improving work efficiency.

[0082] The system supports remote program upgrades and multi-device communication. Its 30,000-hour trouble-free operation design reduces maintenance frequency. The RS485 serial port is compatible with 32 data acquisition devices, leaving ample room for future technology iterations.

[0083] The temperature and humidity sensor provides real-time data feedback via RS485 Modbus RTU protocol. The PLC programmable control system 50 automatically triggers the constant temperature and humidity machine to ensure that the temperature and humidity inside the display case remain stable within the preset range, thus avoiding damage to cultural relics caused by excessive temperature and humidity fluctuations in traditional display cases.

[0084] The electrical control box's heat dissipation is controlled by temperature and humidity sensors that link the cooling fan to start and stop intelligently, preventing the heat generated by the equipment from affecting the internal microenvironment of the display case and ensuring that high-level cultural relics meet the stringent requirements of the storage environment.

[0085] Toxic and harmful gas sensors monitor the concentration of formaldehyde, sulfur dioxide, and other substances in real time. When the concentration exceeds the standard, an alarm is triggered and protective measures are provided to prevent cultural relics from being corroded by pollutants and to protect the health of management personnel.

[0086] Vibration sensors monitor abnormal vibrations such as external impacts and earthquakes in real time, triggering a combined audible and visual alarm. A single alarm can accurately locate the target display case, while multiple alarms can evacuate personnel on site, effectively preventing the risk of theft or damage to cultural relics.

[0087] During the movement of the display case, ultrasonic sensors 31 monitor obstacles in real time and stop immediately upon encountering people, animals, or objects, ensuring the personal safety of visitors and staff in the venue and improving the safety of venue operations.

[0088] Example 2:

[0089] Based on the autonomous movement and display control system of the Wenbo Intelligent Digital Display Cabinet, including:

[0090] The intelligent digital display cabinet system includes: 5. Upper computer; 1. Tablet operating terminal; 3. Bottom drive device; 6. Drive control device; 7. Intelligent digital cabinet control device; 8. Wireless monitoring terminal group and base station.

[0091] The intelligent digital cabinet control device 8 has a built-in PLC programmable control system 50, which is used to communicate with the host computer 1, the tablet operation terminal 3, the drive control device 7, the wireless monitoring terminal group and the base station, to receive and parse control commands and environmental data, and to output regulation and alarm signals; the wireless monitoring terminal group includes a wireless carbon dioxide monitoring terminal, a wireless formaldehyde monitoring terminal and a wireless volatile organic compound monitoring terminal.

[0092] The wireless carbon dioxide monitoring terminal has a measurement range of 0–2000 ppm and an accuracy of 60 ppm ± 2%.

[0093] The wireless formaldehyde monitoring terminal has a measurement range of 0–10 ppm and a measurement accuracy of 0.02 ppm ± 4%.

[0094] The wireless volatile organic compound monitoring terminal has a measurement range of 0-20 ppm (isobutylene), a resolution of 0.01 ppm, and an accuracy of 0.1 ppm ± 8% of the indicated value. All three types of terminals adopt a safety design guided by cultural relic safety and have dual power supply capabilities of battery and wired power.

[0095] The base station uses the National Radio Regulatory Commission's application-free frequency band and has the capabilities of self-organizing network, periodic heartbeat packets, recording and reporting routing information, link quality detection and data verification. The wireless network gateway is connected to the host computer 1 remotely, with a transmission power ≤22dBm and a communication distance greater than 200 meters for line-of-sight transmission.

[0096] The bottom of the intelligent digital display cabinet system 5 is connected to the bottom drive device 6, and it has a built-in constant temperature and humidity machine, cooling fan and intermediate relay, which, together with the wireless monitoring terminal group, realizes environmental monitoring and control.

[0097] Specifically, the professional software interface 2 configured on the host computer 1 corresponds to the environmental monitoring software system, which has the functions of setting monitoring points and parameters, professional data analysis, list or graphical display, real-time alarm, and historical data query.

[0098] The environmental monitoring software system can be deployed in a domestically developed information technology environment and provides an interface to connect to the Zhejiang University Cloud Data Center. Before the system goes online, it must undergo penetration testing by a third-party organization and provide a test report. The vulnerability repair rate is 100%.

[0099] Specifically, the drive control device 7 is equipped with a lidar autonomous navigation system 30, an ultrasonic sensor 31, and a QR code camera 33, and is connected to the intelligent digital cabinet control device 8 to receive instructions and collect navigation and positioning data.

[0100] The bottom drive device 6 is equipped with a servo motor 32, a servo motor drive wheel 34, an auxiliary universal wheel 40 and a backup power supply. It is powered by the backup power supply and drives the servo motor drive wheel 34 through the servo motor 32, and moves the display case in conjunction with the auxiliary universal wheel 40.

[0101] The tablet operating terminal 3 is equipped with a tablet-specific software operating interface 4, a movement speed setting 25, and directional keys, which are used to send movement control commands via wireless WIFI after entering a password.

[0102] The system's hardware deployment follows the principle of "one or more types of devices are configured every 4 meters for each independent cabinet, flat cabinet, and through cabinet." Wireless carbon dioxide monitoring terminals, wireless formaldehyde monitoring terminals, and wireless volatile organic compound monitoring terminals are installed within the intelligent digital display cabinet system 5. This ensures that the terminals are connected to the PLC programmable control system 50 of the intelligent digital cabinet control device 8 via the RS485 communication protocol. Base stations are strategically deployed within the venue to ensure remote connection between the base stations and the host computer 1, covering all display cabinet areas with a communication distance exceeding 200 meters for line-of-sight transmission. The base station transmission power is adjusted to ≤22dBm, and the frequency band is exempt from application by the National Radio Regulatory Commission.

[0103] Software Deployment: Deploy the environmental monitoring software system in a domestically developed environment and complete the interface connection with the Zhejiang Museum Cloud Data Center to ensure smooth data synchronization; before the system goes live, entrust a third-party organization to conduct penetration testing, complete 100% repair of the vulnerabilities found in the test and obtain a test report; install a professional software interface on the host computer 1, and connect the tablet terminal 3 to the venue's wireless WIFI and install a dedicated software interface 4.

[0104] System debugging: Start the PLC programmable control system 50 of the intelligent digital cabinet control device 8, and complete the communication debugging with the host computer 1, tablet operation terminal 3, drive control device 7, wireless monitoring terminal group and base station; set environmental monitoring parameter thresholds such as formaldehyde concentration alarm value of 0.08mg / m³, test data acquisition, analysis and display functions, and ensure that the list or graphical display is normal; simulate data exceeding the standard scenario to verify the effectiveness of the real-time alarm function; test the historical data query and download function to ensure data storage integrity.

[0105] Autonomous movement test: Enter the password through the professional software interface 2 of the host computer 1, select the IP address 21 of the display case to be moved and the target backup IP location 20, and issue a movement command after confirming that the target location is empty; the lidar autonomous navigation system 30 collects path data, the ultrasonic sensor 31 monitors obstacles, the PLC programmable control system 50 plans the path and drives the bottom drive device 6 to realize the movement of the display case; after the display case moves to the vicinity of the target location, the QR code camera 33 reads the QR code to calibrate the position, and stops when the deviation value is less than the preset threshold, thus completing the accurate positioning; during this period, simulated obstacle obstruction is used to test the display case's stopping and detour functions.

[0106] Daily operation: When the system is running normally, the wireless monitoring terminal group continuously collects environmental data, which is transmitted to the intelligent digital cabinet control device 8 via the base station and then synchronized to the environmental monitoring software system of the host computer 1. Managers can remotely view real-time data and historical curves, receive alarm information, and remotely control cabinet door opening and closing, lighting adjustment, and start and stop of the constant temperature and humidity machine through the host computer 1 or tablet operation terminal 3. Historical data is exported through the environmental monitoring software system regularly to conduct analysis and optimization of the cultural relic storage environment.

[0107] Display case movement and environmental monitoring using flat panel control mode:

[0108] The tablet operating terminal 3 connects to the venue's wireless WIFI, enters the tablet's dedicated software operating interface 4 and enters the password. The movement speed of the display case is adjusted by setting the movement speed 25. Movement commands are sent by using the up arrow key 27, down arrow key 29, left arrow key 28, and right arrow key 26. The commands are transmitted to the slave PLC of the drive control device 7 via the wireless network. The slave PLC drives the servo motor 32 of the bottom drive device 6 to rotate, and the auxiliary universal wheels 40 are used to realize the movement of the display case.

[0109] During the movement, the ultrasonic sensor 31 continuously monitors the surrounding environment. When an obstacle is detected, the drive signal of the servo motor 32 is immediately cut off, and the display case stops moving. After the obstacle is removed, the movement can be resumed by pressing the directional key again, and the lidar autonomous navigation system 30 assists in correcting the movement trajectory.

[0110] Meanwhile, the wireless monitoring terminal group collects data such as carbon dioxide, formaldehyde, and volatile organic compounds in real time, and transmits them to the intelligent digital cabinet control device 8 via the base station. The PLC programmable control system 50 synchronizes the data to the dedicated software interface 4 of the tablet operation terminal 3. Managers can view the data in real time. If the data exceeds the standard, the tablet operation terminal 3 will trigger an alarm prompt simultaneously, which will facilitate timely on-site handling.

[0111] As can be seen from the above, the wireless monitoring terminal group has met the accuracy standards, dual power supply guarantees, and stable base station transmission. It can accurately collect data on the storage environment of cultural relics, and, together with the environmental monitoring software system, realize digital display, intelligent analysis, real-time alarm and historical data traceability, meeting the stringent requirements of the cultural heritage industry for environmental monitoring. The software system is compatible with the domestic IT environment, connects to the Zhejiang Provincial Museum Cloud Data Center, and has passed penetration testing, demonstrating outstanding compatibility and security.

[0112] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
