Description

Technical Field

[0001] The present invention belongs to the field of scenic spot viewing devices, and in particular relates to a historical urban area landscape audio-visual perception device and method. Background Art

[0002] A historical city area refers to an existing city area that retains the distribution pattern and streetscape features of a specific historical period. When tourists visit a historical city area, the most important viewing experience is to observe the streetscape features and urban planning characteristics within the city area. Although tourists can observe the streetscape in detail when walking through the streets and alleys, they cannot get a holistic impression of the historical city area. In order to provide tourists with a panoramic viewing experience, some scenic spots will set up telescopes or telescopes combined with AR functions at high altitudes.

[0003] Traditional telescopic viewing devices are all pole-type, that is, the pole used to support the telescope or AR telescope is set at a fixed point and has a fixed structure. The adjustment methods of this type of telescopic viewing device only include angle rotation and height adjustment within a limited range. In actual use, the user is required to adjust his or her posture to adapt to the device. Tourists can only use the device at a fixed point. Moreover, since the device is directly set outdoors, overheated or overcooled outdoor conditions will lead to a decrease in tourists' desire to use the viewing device and a shortened usage time. The above-mentioned problems of low freedom of use and great influence of outdoor conditions lead to a low frequency of use of the existing pole-type telescopic viewing devices, and tourists have a shallow experience with them. In view of the above problems, the present invention proposes a historical city landscape audio-visual perception device and method. Summary of the invention

DETAILED DESCRIPTION

[0032] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1

[0034] like Figure 1-8 As shown, the audio-visual perception device for the landscape of the historical urban area of ​​this embodiment includes an AR telescope 8 for overlooking the historical urban area and performing reality enhancement on the landscape of the urban area, and also includes a suspension mechanism, an exhaust mechanism, and an airflow temperature regulating mechanism. The suspension mechanism is used to control the fixed-point lifting and lowering of the AR telescope 8 and to maintain an elastic connection with the AR telescope 8 during the viewing process. The exhaust mechanism cooperates with the airflow temperature regulating mechanism to output a temperature-appropriate airflow covering the human body trunk during the viewing process;

[0035] The exhaust mechanism includes an exhaust curtain 21 for conveying a temperature-appropriate airflow from the back to the user's torso and a winding rack 20 for reeling and unwinding the exhaust curtain 21. One end of the exhaust curtain 21 is connected to the air duct 22 and the other end is fixed to the winding rack 20. The air inlet of the air duct 22 is connected to the airflow temperature regulating mechanism. The air duct 22 is provided with straps 23 for the user to wear on the limbs. The straps 23 are any one of adjustable tightening straps including elastic straps, adhesive straps and magnetic straps.

[0036] The device also includes a power supply system consisting of a battery 28 and a solar panel 4 , and a control system consisting of a control host 30 and a temperature meter 29 .

[0037] When not in use, the AR telescope 8 is always hung at the highest point, the AR telescope 8 is far away from the ground and the top is shielded, which is conducive to reducing the probability of the AR telescope 8 being attacked by rain or snow or hit by foreign objects, and provides effective protection for the AR telescope 8;

[0038] During use, on the one hand, since the suspension mechanism only maintains an elastic connection with the AR telescope 8 during the viewing process, the user can move the head freely and even walk freely within a certain range outside the device, which greatly improves the user's freedom to switch viewing angles during the viewing process. On the other hand, the temperature-appropriate airflow output from the exhaust curtain 21 will rush toward the human body and then disperse, thereby utilizing the temperature-appropriate airflow to cool or warm up tourists, thereby reducing the negative impact of the outdoor environment on the use of the device and improving the user experience of the device.

[0039] Preferably, the suspension mechanism includes a suspension frame for carrying the AR telescope 8, a connection 6 for connecting the AR telescope 8, a detachable suspension rope 5, and a winding mechanism 7 corresponding to the connection 6 and the suspension rope 5, wherein the connection 6 includes a spring rope connected to the AR telescope 8;

[0040] When tourists need to view the scenery, the spring rope on the connection 6 is stretched adaptively with the user's activities. Through the cooperation of the suspension rope 5 and the connection 6 including the spring rope, the AR telescope 8 can be raised and lowered at a fixed point, and the tourists' viewing freedom requirements can be met.

[0041] Preferably, the suspension frame includes a plurality of mounting frames 9 and airbags 10 interspersed therewith, and a vibration sensor 11 is provided on the inner side of the mounting frame 9. The use of the airbag 10 can take into account both the wearing stability and comfort of the AR telescope 8. The vibration sensors 11 at different positions can vibrate at the right time to give the user a direction prompt, which is conducive to improving the convenience and safety of use.

[0042] Preferably, the exhaust mechanism further includes a rotatable mounting sleeve 19, the winding racks 20 include four and correspond one to one with the exhaust curtains 21, the four winding racks 20 are distributed in a rectangular array outside the mounting sleeve 19, the exhaust curtain 21 is an elastic accordion curtain, and a plurality of longitudinal exhaust ports distributed in a linear array are provided on the exhaust curtain 21;

[0043] After the four straps 23 are fixed to the corresponding limbs, the four exhaust curtains 21 are all in a state where one end is fixed to the limbs of the tourist and the other end is fixed to the corresponding winding frame 20. Therefore, after the four exhaust curtains 21 are unrolled and unfolded, they can be combined into a cloak-like structure behind the tourist, thereby achieving the effect of guiding the temperature-appropriate airflow to cover the human body trunk in a large range.

[0044] The accordion curtain itself has the property of being retractable. An elastic metal wire is embedded in the accordion curtain. A number of longitudinal exhaust vents distributed in a linear array are opened on the exhaust curtain 21. When tourists are viewing the scenery freely, the elastic metal wire can be elastically deformed with the movements of the tourists, and the coverage area of ​​the temperature-appropriate airflow can move with the tourists. When the tourists return to the initial position, the elastic metal wire can automatically restore to the initial state, and the exhaust curtain 21 will be pulled back to the initial state, so that it is convenient to roll up after use.

[0045] Preferably, the airflow temperature regulating mechanism comprises a water storage tank 1 embedded in the ground, a bellows 2 is provided on the water storage tank 1, and a mounting sleeve 19 is sleeved on the outer side of the bellows 2, an inner sleeve 13 is provided in the bellows 2, the inner side of the inner sleeve 13 is a hot air cavity and a heating pipe 14 is provided in the hot air cavity, the outer side of the inner sleeve 13 is a cold air cavity and a water-absorbing cotton 15 is provided in the cold air cavity, a plurality of water guide pipes 16 for guiding water from the water storage tank 1 to moisten the water-absorbing cotton 15 are embedded in the water-absorbing cotton 15, a partition net 12 for supporting the heating pipe 14 and the water-absorbing cotton 15 is also provided in the bellows 2, the airflow temperature regulating mechanism also comprises an air inlet fan 18, and the air inlet fan 18 is connected to two air inlet pipes 17 for respectively supplying air to the hot air cavity and the cold air cavity, and the air guide pipe 22 is connected to the cavity outside the partition net 12;

[0046] When the air flow passes through the absorbent cotton 15, the temperature will drop due to the increase in humidity, thereby cooling the air. The air intake fan 18 can be controlled to be connected with the air intake pipe 17 corresponding to the cold air chamber to output the cold air flow. Conversely, the air intake fan 18 can be connected with the air intake pipe 17 corresponding to the hot air chamber to output the hot air flow.

[0047] Preferably, a bracket 3 is provided on the bellows 2, a winding mechanism 7 is provided on the bracket 3, the bracket 3 is a hollow structure and a rainwater collecting mechanism is provided on the bracket 3, the rainwater collecting mechanism comprises a water receiving box 24, the water receiving box 24 is arranged obliquely, the upper end of the water receiving box 24 is an overflow port, a filter screen 25 is provided at the overflow port and the overflow port is connected to the bracket 3, the lower part of the bracket 3 is connected to a water inlet pipe 27 for introducing rainwater into the water storage tank 1, a flap 26 is provided at the lower end of the water receiving box 24, and the flap 26 is rotatably connected to the water receiving box 24 through a torsion spring;

[0048] When rainwater gathers in the water receiving box 24, the water level gradually rises. On the one hand, the overflowing rainwater can enter the bracket 3 through the water inlet pipe 27, and then enter the water storage tank 1 through the water inlet pipe 27. On the other hand, the impurities blocked by the filter 25 in the water receiving box 24 will automatically accumulate toward the flip cover 26. When too much impurities accumulate, the flip cover 26 rotates under the action of pressure, and the impurities are flushed out of the water receiving box 24 by the water flow. The flip cover 26 rotates to the initial position under the action of the torsion spring and continues to store water, thereby achieving a long-term and effective rainwater self-filtration and collection effect.

[0049] The method of viewing the historical city area using the above-mentioned audio-visual perception device is as follows:

[0050] S1. Arrange audio-visual perception devices at the overlooking points of the historical city;

[0051] S2, the tourist stands on the water tank 1, operates the control host 30 to turn on the device, after the device is turned on, the winding mechanism 7 starts to release the wire to make the AR telescope 8 descend, and the height of the descent is 1.3-1.6m from the ground, which is convenient for people of different heights to use;

[0052] S3. The tourist first fixes the four straps 23 on the corresponding limbs, then removes the hanging rope 5, and then puts on and turns on the AR telescope 8 to start viewing. After the AR telescope 8 is turned on, the exhaust mechanism and the airflow temperature control mechanism are turned on synchronously. On the one hand, the winding frame 20 rotates inversely, and the exhaust curtain 21 is gradually unwound and unfolded. On the other hand, the air intake fan 18 injects air into the airflow temperature control mechanism. After passing through the airflow temperature control mechanism, the air is converted into temperature-appropriate air and output. Then, the temperature-appropriate air passes through the air guide 22 into the exhaust curtain 21, and finally passes through the exhaust port on the exhaust curtain 21 for output. The output temperature-appropriate airflow can cover the human body to alleviate the negative impact of the outdoor temperature on the tourist's viewing experience.

[0053] S4, during the viewing process, the tourist wears the AR telescope 8 to look down at the historical city landscape around the device for exploratory viewing. The movable range can be limited by the size design of the spring rope and the exhaust curtain 21. One end of the exhaust curtain 21 moves with the tourist, and the exhaust curtain 21 is elastically deformed with the movement of the free end. The coverage area of ​​the temperature-appropriate airflow output by the exhaust curtain 21 changes with the movement of the tourist, and the temperature-appropriate airflow is continuously delivered to the tourist's torso;

[0054] S5. After the sightseeing is completed, the tourist returns to the initial sightseeing point, removes the AR telescope 8 and installs the suspension rope 5 back to the original position, then closes the AR telescope 8 and removes the strap 23. Then the airflow temperature control mechanism is closed, the winding mechanism 7 and the exhaust mechanism are opened synchronously, the winding mechanism 7 is wound up to raise the AR telescope 8 to the initial position, and the winding frame 20 is rotated to roll up the exhaust curtain 21.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
