Description

Technical Field

[0001] The utility model relates to the technical field of communication, and particularly relates to an intelligent data acquisition gateway. Background Art

[0002] The intelligent data acquisition gateway is an important part of the Internet of Things system, mainly responsible for connecting various Internet of Things devices, sensors and cloud servers to realize data acquisition, transmission and processing. As a transfer station for the Internet of Things data stream, the intelligent data acquisition gateway can integrate and forward data from different devices to the cloud platform, providing basic support for subsequent data analysis and applications.

[0003] The existing intelligent data acquisition gateway dissipates heat through heat sinks evenly distributed on the outer shell. Different receiving modules inside the gateway often have different data processing intensities. Therefore, the heat generation of different modules inside the gateway is not consistent, and the gateway is difficult to adjust the heat dissipation intensity according to the heat dissipation of the modules, resulting in local overheating inside the gateway, which easily accelerates the aging speed of components and affects the data acquisition efficiency. For this reason, we propose an intelligent data acquisition gateway that can adjust the heat dissipation intensity of modules. Summary of the Utility Model

[0027] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a data acquisition intelligent gateway, including a protective case 1, a central processor 7, a board surface temperature sensor 8 and a mobile fixed-point heat dissipation component. The signal input end of the central processor 7 is connected with a timer and a storage unit.

[0028] The connection port group 4 is plugged with a data acquisition component 18. The data acquisition component 18 includes an air temperature sensor, an air humidity sensor or a PM2.5 sensor. The data acquisition component 18 sends the collected analog signal to the central processor 7, and performs analog-to-digital conversion and filtering amplification on the analog signal through a signal analysis processor 9; both sides of the bottom of the protective case 1 are formed with symmetric inclined surfaces 101. The height of the inclined surface 101 is not less than one-half of the height of the protective case 1. The outer contour of the cross-section of the protective case 1 is in a "V" shape. By setting the protective case 1 with a cross-sectional outer contour in a "V" shape, the heat dissipation area and air flow circulation space of the bottom surface of the protective case 1 can be increased compared with a flat bottom surface.

[0029] The board surface temperature sensor 8 includes a plurality of sensors respectively connected to the signal analysis processor 9 one-to-one. The signal analysis processor 9 includes an analog-to-digital converter, a signal amplifier and a filter circuit.

[0030] The mobile fixed-point heat dissipation component includes a servo motor 10 fixed in the middle of the bottom of the protective case 1. The output end of the servo motor 10 is threadedly connected with a moving platform 12 through a lead screw 11. At least two blowers 15 are connected to both sides of the moving platform 12 through the output ends of steering motors 14. The steering motors 14 include a first motor and a second motor. The two blowers 15 are respectively a first blower and a second blower. The bottom of the first blower is connected to the output end of the first motor, and the bottom of the second blower is connected to the output end of the second motor. A limiting groove 13 is opened at the bottom of the protective case 1, and the limiting groove 13 is movably tangent and clamped with the bottom of the moving platform 12. The output end of the steering motor 14 adjusts the air outlet position of the blower 15. By setting the first blower and the second blower, the first blower and the second blower can blow air at the same or different air outlet angles simultaneously, which is beneficial to increasing the heat dissipation amount in the gateway. Start the servo motor 10, and the output end of the servo motor 10 linearly moves the moving platform 12 through the lead screw 11 in cooperation with the limiting groove 13 to adjust the position of the blower 15.

[0031] Preferably, as Figure 2 shown, a plurality of heat dissipation fins 3 are welded to the bottom of the inclined surface 101. The plurality of heat dissipation fins 3 are linearly arranged at equal intervals. The bottom surface of the heat dissipation fins 3 is coplanar with the bottom surface of the protective case 1. Support rods 102 are respectively fixed at both ends of the bottom of the protective case 1.

[0032] Preferably, as Figure 3 shown, a mesh panel 5 that is co-centered with the connection ports is penetrated and connected to the side side wall of the accommodation groove 2. The mesh panel 5 is an annular wire mesh surface with through holes. The diameter of the through holes does not exceed 3 mm. The mesh panel 5 is beneficial to the heat dissipation of the connection ports. By setting the annular wire mesh surface that is co-centered with the connection ports, the heat dissipation intensity in all directions of the connection ports can be evenly distributed.

[0033] Preferably, as Figure 1 shown, a first dust-proof plate 16 is movably clamped at the top of the accommodation groove 2, and a second dust-proof plate 17 is welded to one side of the accommodation groove 2. Semi-circular depressions 171 with the same center are respectively opened at one ends of the first dust-proof plate 16 and the second dust-proof plate 17. The semi-circular depressions 171 can hold up the connecting wires of the data acquisition component 18.

[0034] Preferably, as Figure 1 shown, equally spaced reinforcing ribs 19 are fixed at the top of the protective case 1, and a dust-proof net 20 is welded between adjacent reinforcing ribs 19. The reinforcing ribs 19 are used to tension the dust-proof net 20.

[0035] Preferably, as Figure 1 shown, the reinforcing ribs 19 are rigid arc plates, and the dust-proof net 20 is an arc-shaped mesh surface with the same curvature as the reinforcing ribs 19, which can expand the contact area with air compared with a flat mesh surface and increase the air intake amount in the protective case 1.

[0036] Working principle: When in use, the sensors included in the data acquisition component 18 are adaptively connected to the connection port, and the wiring of the data acquisition component 18 is adapted to penetrate through the semi-circular recess 171 at the top of the second dust-proof plate 17. The first dust-proof plate 16 is moved to be clamped with the wiring of the data acquisition component 18, so that the connection end of the data acquisition component 18 can be protected from dust by the first dust-proof plate 16 and the second dust-proof plate 17. Different sensors included in the data acquisition component 18 generate different amounts of heat during the signal acquisition process. This heat is detected by the board surface temperature sensor 8 at the corresponding connection port. The board surface temperature sensor 8 sends the detection result to the central processor 7 for temperature sorting. The central processor 7 sends a start signal to the servo motor 10, and the timer calculates the start duration of the servo motor 10, so that the servo motor 10 drives the moving table 12 to move to the position directly opposite the connection port with the highest temperature through the lead screw 11. The steering motor 14 adjusts the air outlet position of the blower 15 at the corresponding position of its output end, and the blower 15 is started. The blower 15 blows air to cool the connection port with the most heat generation, and the hot air flow can be discharged through the through holes on the mesh panel 5 or the dust-proof net 20.
