DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides Figure 1-Figure 7 The urban area ecological environment monitoring system shown can not only be used to monitor the ecological environment of the urban area, but also to timely regulate the ecological environment according to the monitored ecological environment data to maintain a good ecological environment in the urban area.

[0033] The urban area ecological environment monitoring system includes a data acquisition module, a control module, a database and an alarm. Among them, the data acquisition module is used to collect various data values ​​in the urban area ecological environment, and the database is used to store various data values ​​in some common urban area ecological environment. When the data values ​​collected by the acquisition module have a certain degree of deviation from the data values ​​in the database, the alarm will sound an alarm, indicating that the ecological environment needs to be regulated. At this time, the ecological environment is timely regulated through the control module.

[0034] During specific use, the output end of the data acquisition module is connected to the input end of the controller, the controller is bidirectionally connected to the database, the output end of the controller is connected to the input end of the alarm, and the output end of the controller is connected to the input end of the control module. The controller is used to control and coordinate the cooperation between the modules.

[0035] In actual use, the data acquisition module includes but is not limited to low-definition monitors, infrared sensors, air pressure sensors, light brightness sensors, humidity sensors and temperature sensors. The data acquisition module can be mounted on a mobile mechanism, such as a car, a drone, a ship, etc. The mobile mechanism controls the inspection route through the existing control program, and then carries the data acquisition module to conduct inspection and collection on this route, thereby achieving the purpose of automatic data collection.

[0036] Among them, low-definition monitors can be used to monitor abnormal situations in the ecological environment of urban areas, such as: damage to the ecological environment, fire, etc.; infrared sensors can be used to monitor people or objects with body temperature in the ecological environment of urban areas, and then use low-definition monitors to warn or deal with people or objects. For example, when someone tramples on the lawn, the infrared sensor detects that the person is approaching the lawn area, and the low-definition monitor also detects that the person is approaching the lawn area, so that the alarm sounds and warns people not to trample on the lawn through the speaker in the alarm.

[0037] The air pressure sensor can be used to monitor the pressure of the atmospheric environment in the ecological environment of urban areas. It is usually used in the ecological environment of urban indoor areas. If the atmospheric pressure in the ecological environment of urban indoor areas is not suitable, it is easy to adjust it in time through the control module.

[0038] Light illumination sensors are also commonly used to monitor the light intensity in the ecological environment of urban indoor areas. If the light intensity is insufficient, it is convenient to adjust the indoor light intensity in time through the control module.

[0039] Humidity sensors and temperature sensors can be used both indoors and outdoors. Humidity sensors are used to monitor the air humidity in the ecological environment, and temperature sensors are used to monitor the temperature in the ecological environment. If the humidity or temperature is not suitable, it can be adjusted in time through the control module.

[0040] It should be noted that when the mechanism for adjusting temperature or humidity in the control module is applied outdoors, there is only a difference in effect, but it can still produce a certain effect in a certain area and achieve the purpose of regulating the ecological environment of the urban area.

[0041] The urban area ecological environment monitoring system of the present invention is particularly suitable for monitoring parks, roadside landscapes, lakes, etc. in cities.

[0042] The control module includes a high-definition monitor, an automatic fire extinguisher, an air conditioner, a voltage regulating component, a humidifier and a lighting component; the high-definition monitor is a high-definition camera arranged in the ecological environment of the urban area, such as: high-definition cameras arranged in various positions of the park, with high definition and clear monitoring images, but due to the high cost of such high-definition cameras, the present invention can reduce the number of high-definition cameras arranged after combining with the low-definition monitor in the urban area ecological environment monitoring system; the specific principle is: after the low-definition monitor (low-definition camera) monitors the existence of abnormal conditions in the ecological environment of the urban area, the high-definition camera at the corresponding position can be controlled by the controller to rotate toward this area, so as to obtain a clearer picture, thereby reducing the cost while improving the monitoring range and monitoring clarity.

[0043] Automatic fire extinguishers are existing automatic fire extinguishing devices such as robot fire extinguishers. If the urban area ecological environment monitoring system detects a fire, the automatic fire extinguisher can be controlled by the controller to move to this area to extinguish the fire, thereby achieving the purpose of automatic fire extinguishing and avoiding the phenomenon of greater losses caused by personnel failing to arrive in time.

[0044] Air conditioners, voltage regulating components and lighting components are equipment installed in the ecological environment of urban indoor areas. When the temperature in the ecological environment of urban indoor areas is abnormal, it is adjusted through air conditioners. When the atmospheric pressure in the ecological environment of urban indoor areas is abnormal, it is adjusted through voltage regulating components. When the light intensity in the ecological environment of urban indoor areas is low, it is adjusted through lighting components.

[0045] It should be noted that the pressure regulating component can use components such as pressure fans, the lighting component can use components such as LED lights, and the urban area ecological environment monitoring system is powered by a power module. These are all common existing technologies and will not be elaborated here.

[0046] The low-definition monitor of the present invention comprises an outer shell 1, which has a semi-elliptical shell structure. An inner shell 17 is movably arranged inside the outer shell 1, and the inner shell 17 has a hemispherical shell structure. A bottom spherical shell 21 is integrally arranged at the inner circle of the inner shell 17, and a camera 2 is arranged in the bottom spherical shell 21.

[0047] In order to enable the low-definition monitor to be better used in conjunction with the high-definition monitor in the present invention, a lens 8 and an LED fill light 9 are arranged on the front side of the camera 2. Two LED fill lights 9 are arranged, and the two LED fill lights 9 are symmetrical about the lens 8. When working, the camera 2 uses the lens 8 to shoot and monitor, and the LED fill light 9 is used to fill light for the scene shot by the lens 8 when it is started.

[0048] Side ears 7 are fixedly welded at both ends of the lower surface of the inner shell 17, and a rotating shaft 10 is fixedly set at both ends of the camera 2. The rotating shaft 10 is rotatably set on the inner wall of the side ear 7. A first motor slot 20 is set inside one of the side ears 7, and a first motor 19 for driving the rotating shaft 10 to rotate is fixedly installed in the first motor slot 20. When the first motor 19 is started, it can drive the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, it drives the camera 2 to rotate around the rotating shaft 10 as the axis, thereby realizing the adjustment of the shooting angle of the camera 2.

[0049] An air cavity 16 is formed between the inner ring of the outer shell 1 and the outer ring of the inner shell 17, and a second motor 32 is fixedly installed on the inner wall above the air cavity 16. A second motor shaft 35 is provided at the lower end of the second motor 32. A connecting sleeve 41 is fixedly welded to the middle part of the upper surface of the inner shell 17, and the second motor shaft 35 is fixedly installed on the connecting sleeve 41 by screws. When the second motor 32 is started, the inner shell 17 can be driven to rotate by the second motor shaft 35. When the inner shell 17 rotates, the camera 2 rotates synchronously, thereby achieving the purpose of adjusting the horizontal rotation angle of the camera 2.

[0050] A threaded hole 29 is provided in the middle of the upper end of the outer shell 1, and a fixing column 6 is connected to the threaded hole 29 by threaded cooperation. The fixing column 6 has a cylindrical structure, and a bracket 3 is fixedly provided on one side of the outer circle of the fixing column 6. The bracket 3 has an arc-shaped plate-like structure, and a fixing plate 4 is fixedly provided on the end of the bracket 3 away from the fixing column 6. When the outer shell 1 and the camera 2 in the present invention are used, the camera 2 is first installed on the outer shell 1, and then the fixing column 6 is rotated and connected to the threaded hole 29 at the upper end of the outer shell 1, and the fixing plate 4 at the end of the bracket 3 is fixed in a suitable position by screws for use.

[0051] In order to solve the problem that it is difficult to clean the camera surface when dust adheres to it, and the dust in the gaps around the lens and the gaps around the fill light of the existing fill light camera is even more difficult to clean, a bracket box 11 is fixedly arranged on the bottom spherical shell 21, and three bracket boxes 11 are arranged. A groove is arranged on one side of the three bracket boxes 11 close to the outer circle of the camera 2, and a wiping cotton layer 39 that is movably fitted to the outer circle of the camera 2 is arranged in the groove. An elastic rod 38 is fixedly welded on the inner wall of the bracket box 11, and a plurality of elastic rods 38 are arranged. The plurality of elastic rods 38 are equidistantly distributed, and the end of the elastic rod 38 is fixed to the side of the wiping cotton layer 39 away from the outer circle of the camera 2. The three wiping cotton layers 39 are respectively connected to the lens 8 and the two LED fill lights. Corresponding to the LED fill light 9, when the first motor 19 is started, during the process of adjusting the shooting angle of the camera 2, the camera 2 passes through the wiping cotton layer 39, and the wiping cotton layer 39 at the corresponding position can wipe the dust on the surface of the lens 8 or the LED fill light 9, thereby achieving the purpose of automatic dust cleaning when adjusting the shooting angle, and the dust prevention effect is good; and because an elastic rod 38 is arranged inside the bracket box 11, the elastic rod 38 has a certain elasticity, and a plurality of elastic rods 38 are arranged, when the wiping cotton layer 39 passes through the surface of the lens 8 or the LED fill light 9, the wiping cotton layer 39 will be pushed to be pressed against the surface of the lens 8 or the LED fill light 9, and a plurality of elastic rods 38 resist the wiping cotton layer 39 to better clean the dust in the gap between the lens 8 and the LED fill light 9, and the cleaning effect is good.

[0052] In order to facilitate the arrangement of other parts, the three bracket boxes 11 are distributed at equal distances, and the height of the middle bracket box 11 is higher than the bracket boxes 11 on both sides thereof. The bracket boxes 11 can also be used to install other parts at the same time, and are highly practical. A control component 13 is fixedly installed on the upper surface of the middle bracket box 11, and fans 12 are installed on the upper surfaces of the bracket boxes 11 on both sides. The fans 12 face the bottom of the control component 13, and the fans 12 can dissipate heat for the control component 13 when started, and the fans 12 transmit wind power to the bottom of the control component 13, thereby increasing the heat dissipation effect of the control component 13, and replacing the phenomenon in the prior art that the heat of the direct blowing heat dissipation is easily accumulated at the bottom of the control component 13.

[0053] It should be noted that the control component 13 includes a control mainboard, a converter, and the like.

[0054] An air inlet 37 is formed at the lower end of the air cavity 16, and an air inlet hole 36 communicating between the inner shell 17 and the air cavity 16 is provided at a position near the fan 12 on the inner shell 17, and the air inlet hole 36 is located above the filter cotton ring 14, and a plurality of air inlet holes 36 are provided along the outer ring of the inner shell 17, and a second exhaust air duct 34 communicating between the inner shell 17 and the air cavity 16 is provided at the upper end of the inner shell 17, and a heat dissipation slot 5 is provided at the upper end of the outer shell 1, and the heat dissipation slot 5 is provided with two, and the two heat dissipation slots 5 are about the fixing column 6 Symmetrically, a first exhaust air duct 30 is arranged on the inner wall of the side of the heat dissipation slot 5, and the lower end of the first exhaust air duct 30 is connected to the inside of the ventilation cavity 16. When the fan 12 is started, suction is generated and the external wind is sucked into the bottom of the control component 13 for heat dissipation. The external wind passes through the air inlet 37, the air cavity 16, and the air inlet hole 36 in sequence, and is then sucked into the bottom of the control component 13 by the fan 12. After the control component 13 is cooled, the wind passes through the second exhaust air duct 34, the air cavity 16, the first exhaust air duct 30 and the heat dissipation slot in sequence. 5 is discharged. In the present invention, the air inlet 37 is an air inlet, and the air inlet 37 is an annular structure. When air enters the air inlet 37, a flowing airflow is formed around the camera 2, so that dust and impurities are not easily attached to the surface of the camera 2, and the dustproof performance is good. The first exhaust air duct 30 is an air outlet, but the first exhaust air duct 30 is only symmetrically provided with two. Therefore, the wind force of the wind out of the first exhaust air duct 30 is greater than the wind force of the wind entering the air inlet 37. When a lighter foreign object such as a balloon blocks the vicinity of the lens 8 of the camera 2, the balloon will The balloon will continue to rise because the outer ring of the outer shell 1 and the camera 2 are both smooth curved surfaces. After that, lighter foreign objects such as balloons will be blown away by the wind discharged from the first exhaust duct 30 and away from the camera 2, thus avoiding the phenomenon that lighter foreign objects such as balloons block the camera 2. The present invention solves the problem of lighter foreign objects such as balloons blocking the camera 2 and preventing the camera 2 from being used normally based on the reasonable setting of the air inlet and outlet.

[0055] The lower end of the wind cavity 16 is provided with a filter cotton ring 14 blocking the top of the air inlet 37. The filter cotton ring 14 has an annular structure. The outer ring of the filter cotton ring 14 is fixedly bonded to the inner ring of the outer shell 1, and the inner ring of the filter cotton ring 14 is movably fitted to the outer ring of the inner shell 17. The setting of the filter cotton ring 14 avoids the phenomenon of dust and other impurities entering the wind cavity 16, and has a filtering effect on the wind entering the wind cavity 16.

[0056] In order to make the wind better pass through the air inlet 37, the air cavity 16, the air inlet hole 36 in sequence, and then be sucked into the bottom of the control component 13 by the fan 12, and then be discharged through the second exhaust duct 34, the air cavity 16, the first exhaust duct 30 and the heat sink 5 in sequence. Elastic baffles 31 are provided at the opening of the first exhaust duct 30 connected to the heat sink 5, the end of the second exhaust duct 34 connected to the ventilation cavity 16, and the end of the air inlet hole 36 connected to the inside of the inner shell 17, so that the wind passing through the air inlet hole 36, the second exhaust duct 34 and the first exhaust duct 30 can only flow in one direction and cannot flow back, thus avoiding the phenomenon of water, wind, dust and the like entering the first exhaust duct 30. The outer circle of the elastic baffle 31 is fixedly bonded to the corresponding wall structure, and a magnetic baffle 31 is also fixedly provided on the elastic baffle 31. Block 33, the magnetic block 33 and the corresponding wall structure are attracted to each other, and the elastic baffle 31 itself has a certain elasticity. When the elastic baffle 31 is pushed by wind force, the elastic baffle 31 opens, thereby opening the corresponding air inlet hole 36, the second exhaust air duct 34 and the first exhaust air duct 30. When the elastic baffle 31 loses the push of wind force, the elastic baffle 31 will use the suction force of the magnetic block 33 to be adsorbed on the corresponding wall structure, thereby achieving the purpose of sealing the corresponding air inlet hole 36, the second exhaust air duct 34 and the first exhaust air duct 30.

[0057] In order to further increase the heat dissipation of the camera 2, a first storage chamber 15 is provided in the wall structure layer of the outer shell 1. The first storage chamber 15 stores a cooling liquid. The cooling liquid is wrapped around the outer shell 1, so that the heat on the camera 2 can be better dissipated, and the heat of the outer shell 1 and the camera 2 as a whole is kept uniform, thereby avoiding overheating of some parts inside the outer shell 1 and the camera 2.

[0058] A hollow cavity 27 is provided inside the fixing column 6, and a circular hole 28 is provided at the outer circle of the lower end of the hollow cavity 27. There are multiple circular holes 28, and the multiple circular holes 28 are distributed at equal angles along the fixing column 6. A heat dissipation channel 40 is provided on the inner wall of the threaded hole 29, and one end of the heat dissipation channel 40 is connected to the circular hole 28, and the other end of the heat dissipation channel 40 is connected to the inside of the first storage chamber 15. A rainwater inlet hole 24 is provided on the upper end surface of the fixing column 6, and the rainwater inlet hole 24 is connected to the inside and outside of the hollow cavity 27; When it rains, rainwater can enter the hollow cavity 27 through the rainwater inlet hole 24. The rainwater inside the hollow cavity 27 then flows into the first storage chamber 15 through the circular hole 28 and the heat dissipation channel 40 in turn for storage, replenishing the cooling liquid in the first storage chamber 15. The cooling liquid in the first storage chamber 15 is rainwater. A filter cotton pad 25 is fixedly arranged in the rainwater inlet hole 24. The filter cotton pad 25 serves the purpose of filtering rainwater to prevent impurities in the rainwater from entering the first storage chamber 15.

[0059] The heat dissipation principle of the outer shell 1 and the camera 2 by rainwater is as follows: the heat inside the outer shell 1 or the heat on the camera 2 is transferred to the rainwater through the inner wall of the outer shell 1, and the rainwater is heated in the first storage chamber 15 and then evaporates rapidly. During the volatilization, the water vapor is discharged in sequence through the heat dissipation channel 40, the circular hole 28, the hollow cavity 27 and the rainwater inlet hole 24. When the rainwater evaporates, it takes away the heat, thereby achieving the purpose of rapid heat dissipation.

[0060] Considering that the wall structure layer of the outer shell 1 will not be too thick, the first storage chamber 15 arranged in the wall structure layer of the outer shell 1 is relatively small in volume. Considering that the bracket 3 is usually made of a hollow stainless steel shell, in order to make full use of the bracket 3 and solve the problem of the small amount of rainwater stored in the first storage chamber 15, a second storage chamber 18 is arranged inside the bracket 3. The upper end of the second storage chamber 18 is connected to the hollow cavity 27 through a connecting port 22. The connecting port 22 is opened on the outer wall structure of the fixed column 6. When the rainwater in the first storage chamber 15 is too full, it will flow into the second storage chamber 18 along the heat dissipation channel 40, the circular hole 28, the hollow cavity 27, and the connecting port 22 in sequence for storage, thereby increasing the amount of stored rainwater.

[0061] In order to prevent rainwater entering from the rainwater inlet hole 24 from flowing directly to the side into the second storage chamber 18, a shielding plate 23 is provided at the upper end of the hollow cavity 27. The shielding plate 23 is arranged obliquely. One end of the shielding plate 23 is fixedly welded to an inner wall of the hollow cavity 27 near the connecting port 22. The other end of the shielding plate 23 is inclined downward, and a through gap 26 is formed between the other end of the shielding plate 23 and the inner wall of the hollow cavity 27. The shielding plate 23 has a certain guiding effect on the rainwater entering from the rainwater inlet hole 24, so that the rainwater flows from the through gap 26. 26 is discharged into the bottom of the hollow cavity 27, and the opening of the gap 26 is small, so that the amount of rainwater volatilization becomes smaller, so that the rainwater in the first storage chamber 15 and the second storage chamber 18 can be continuously used for the heat dissipation of the outer shell 1 and the camera 2; when the rainwater in the second storage chamber 18 evaporates, it can also be blocked by the baffle plate 23 and condensed to form water droplets and drip on the bottom of the hollow cavity 27, thereby achieving the purpose of transferring the rainwater in the second storage chamber 18 to the first storage chamber 15, so that the rainwater in the first storage chamber 15 can be automatically replenished.

[0062] An expansion joint is arranged in the middle of the fixing plate 4. The expansion joint is a rectangular groove structure arranged on the side of the fixing plate 4 away from the bracket 3. When the fixing plate 4 is fixed to the wall or other structure by screws, it has a certain degree of retractability, so that the fixing plate 4 can better fit the surface of the wall or other structure, thereby increasing the stability of the fixing plate 4 during installation.
