[0025] It also includes a drying component, which includes two L-shaped plates 15 fixedly connected to the upper end of the base plate 1. Electric heating plates are installed on the inner tops of the two L-shaped plates 15. The two electric heating plates can provide sufficient heat to quickly dry the water-absorbing roller 19, ensuring that the water-absorbing roller 19 recovers its water absorption performance in a short time, so as to continuously and effectively wipe the moisture on the base plate 1.

[0026] Among them, it also includes an environmental monitoring module. The environmental monitoring module includes an environmental sensor 11 installed at the upper end of the top plate 3. A display module and an operation module are provided on the display screen 28. The display module is used to display environmental information on the display screen 28 according to the signals of the environmental sensor 11. Tourists can use the operation module to query scenic area information and scenic spot routes.

The sound collection module has high sensitivity and anti-interference ability and can accurately receive tourists' voice commands, clearly identifying them even in a noisy environment. Combined with natural language processing technology, it provides accurate and detailed intelligent question answering services for tourists, enhancing the interactivity and practicality of the device.

[0027] The functional principle of the present invention can be elaborated through the following operation method: In the normal state, the first motor 4 rotates clockwise, so that the disc 40 drives the second infrared distance sensor 41 and the display screen 28 to rotate. When a tourist stands on the bottom plate 1 and the second infrared distance sensor 41 rotates to the top of the tourist's head, it will automatically detect the tourist's height and transmit it to the control unit inside the display screen 28. Then the control unit will control the operation of the height adjustment component and control the first motor 4 to stop running. At this time, the pneumatic rod 39 will stretch accordingly, driving the display screen 28 to descend and adjusting the display screen 28 to a height position suitable for the tourist's height. When the tourist is relatively short, at this time the display screen 28 cannot descend to be level with the tourist's line of sight. At the same time, the first infrared distance sensor 27 will sense the position of the lifting block 30 and generate an electrical signal to transmit to the control unit. The control unit combines the tourist's height detected by the second infrared distance sensor 41 and will control the electromagnet 34 to be energized (the current passing through the electromagnet 34 will be adjusted according to the tourist's height. The shorter the tourist's height, the greater the current passing through the electromagnet 34. At this time, the rotation angle of the display screen 28 will be larger). After the electromagnet 34 is energized, it will attract the iron block 36, and then the iron block 36 will drive the rack 37 to move to the right, so that the display screen 28 rotates downward, enabling tourists with relatively short heights to also have a better angle to view the scenic area information on the display screen 28.

[0028] During the rotation of the first motor 4, the rotation of the rotating rod 5 drives the thin rod to rotate through the first transmission assembly 12, and then drives the fan 10 to rotate. External air enters the filter box 7 through the air inlet of the filter box 7. Inside the filter box 7, impurities such as dust in the air are filtered, and the purified air is transported to the annular hollow plate 21 through the connecting pipe 8. Multiple air outlets below the annular hollow plate 21 discharge the purified air, forming an air barrier around components such as the display screen 28, preventing external dust from approaching components such as the display screen 28, thus effectively filtering the dust in the air, reducing the pollution of components such as the display screen 28 by dust, and ensuring that the display screen 28 always maintains a high clarity.

[0029] On a rainy day, when there is accumulated water on the bottom plate 1, the wiping assembly starts to work. At this time, the environmental sensor 11 will transmit the corresponding signal to the control unit, and the control unit controls the first motor 4 to rotate in the reverse direction, driving the bidirectional threaded rod 20 to rotate through the transmission structure. Since the moving blocks 18 are threadedly connected to the bidirectional threaded rod 20, the two moving blocks 18 will continuously move relative to or away from each other as the bidirectional threaded rod 20 rotates. The movement of the moving blocks 18 drives the rotating shafts 24 rotatably connected thereto and the water absorption rollers 19 fixed on the rotating shafts 24 to move synchronously. The water absorption rollers 19 come into contact with the bottom plate 1 during the movement, absorbing the water on the bottom plate 1, thus preventing the water on the bottom plate 1 from causing the soles of tourists to slip and ensuring the safety of tourists when using the device.

[0030] On a rainy day, after the first motor 4 runs for a period of time (completes one water absorption operation cycle) each time, the first motor 4 will run in the reverse direction. At the same time, the control circuit of the device will make the two electric heating plates and the second motor 16 in the energized state. The second motor 16 starts. Since the two water absorption rollers 19 are in the initial position and the two first gears 17 are in the meshed state at this time, the operation of the second motor 16 will drive the two rotating shafts 24 to rotate, and then make the two water absorption rollers 19 rotate. During the rotation of the water absorption rollers 19, the heat emitted by the two electric heating plates dries the water absorption rollers 19, removing the water absorbed by the water absorption rollers 19, so that the water absorption rollers 19 can maintain good water absorption performance and can repeat the water absorption work for a long time.

[0031] The environmental sensor 11 in the environmental monitoring module continuously and real-time monitors the environmental conditions in the scenic area, such as environmental parameters like air quality, temperature, humidity, etc. The data monitored in real time will be transmitted to the display module of the display screen 28, and the display module will display the environmental information on the display screen 28 in an intuitive manner, enabling tourists to timely understand the environmental conditions in the scenic area. When tourists need to query scenic area information or scenic spot routes, they can send requests to the device by means of voice commands. The sound collection module (integrated within the display screen 28) receives the voice commands of tourists and converts them into electrical signals for transmission to the processing unit inside the display screen 28. The processing unit analyzes and understands the voice commands based on natural language processing technology, and then retrieves corresponding scenic area information, scenic spot route data, etc. from the database. This data is on the one hand displayed to tourists through the display screen 28, and on the other hand transmitted to the speaker 29 through the sound amplification module (connected to the speaker 29), and the speaker 29 plays the query content in the form of voice, realizing the functions of voice interaction and intelligent question and answer, and meeting the diverse and personalized service needs of tourists.
