An industrial intelligent control computer based on big data

Abstract

This invention provides an industrial intelligent control computer based on big data. The swing assembly includes a dust collection box, a baffle, a first fan blade, a second fan blade, a shaft arm, and a hinge. The dust collection box is installed inside the motherboard, and the baffle extends through the interior of the dust collection box. Both the first and second fan blades swing outside the output shaft, and the shaft arm swings to the sides of the first and second fan blades. The hinge is hinged to the joint of the shaft arm. The angle between the shaft arm on the side of the second fan blade and the shaft arm on the side of the first fan blade is reduced. Due to the high rotation speed of the output shaft, the side of the second fan blade quickly expands to one end of the first fan blade. The vibration generated by the collision between the second and first fan blades helps the dust on the upper part of the second and first fan blades fall downwards. The dust falls downwards into the interior of the dust collection box, and the baffle inside the dust collection box prevents the dust from splashing upwards again to the outside of the first and second fan blades.

Description

Technical Field

[0001] This invention relates to the field of industrial control technology, and in particular to an industrial intelligent control computer based on big data. Background Technology

[0002] Industrial intelligent control computers are mainly used for industrial control and testing. A typical application of an industrial computer is to obtain external data through a standard serial port, perform calculations through the computer's internal microprocessor, and finally output the data through a display screen or serial port. Industrial intelligent control computers are usually cooled by cooling fans or heat sinks. This article provides technical insights into intelligent control computers.

[0003] Research on intelligent control computers has revealed the following problems:

[0004] Because industrial intelligent control computers have multiple electronic components installed inside, cooling fans are needed to assist in cooling these components. However, cooling fans are usually installed inside the industrial intelligent control computer. After prolonged use, the fan blades accumulate a lot of dust. This dust easily splashes upwards onto the surface of the electronic components inside the industrial intelligent control computer during the operation of the cooling fan, thus preventing the cooling fan from cleaning the dust on the fan blade surface when it starts up.

[0005] Currently, the existing technology CN201911065816.1 discloses an industrial control computer. This invention provides an anti-loosening read magnetic device at the disk of the industrial control computer. It can use the slight wind force generated when the disk shakes to adjust the angle of the pressing handle. Through its cooperation with the inclined block on the read magnetic frame, it corresponds to the pressing force of the read magnetic frame, ensuring effective contact between the read magnetic needle and the disk. This prevents the disk's read and write capabilities from decreasing, the head from being positioned slowly, or even the disk from being damaged, thus effectively protecting the information storage system of the industrial control computer.

[0006] This invention primarily addresses the problem of excessive dust accumulation on the blades of intelligent computer cooling fans after prolonged use. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides an industrial intelligent control computer based on big data, thereby resolving the issues described in the background section.

[0008] The purpose and effectiveness of this invention, an industrial intelligent control computer based on big data, are achieved by the following specific technical means: an industrial intelligent control computer based on big data includes a frame, a mounting base at the lower end of the frame, and a control component at the upper end of the mounting base. The control component includes a motherboard, a microprocessor, and a circuit board. The microprocessor is located at the upper end of the motherboard, while the motherboard and circuit board are both located inside the frame. A cooling fan rotates at the upper end of the motherboard, and an output shaft rotates at the upper end of the cooling fan. Heat dissipation meshes are provided on both sides of the frame.

[0009] Furthermore, the frame is fixed in place by the internal through bolts of the mounting base.

[0010] Furthermore, the motherboard is a computer motherboard, the microprocessor is connected to the circuit board, the circuit board is a control circuit board, and the frame has a socket near the motherboard. The socket contains a movable fiber optic cable, and the microprocessor and the circuit board are connected to the external control terminal through the fiber optic cable.

[0011] Furthermore, the cooling fan is equipped with a motor inside, which is connected to the circuit board. The motor drives the output shaft to rotate 360°. The cooling fan is equipped with an oscillating component inside and at the top.

[0012] Furthermore, the swing assembly includes a dust collection box, a baffle, a first fan blade, a second fan blade, a shaft arm, and a hinge. The dust collection box is installed inside the motherboard, the baffle passes through the inside of the dust collection box, the first fan blade and the second fan blade swing outside the output shaft, the shaft arm swings on the side of the first fan blade and the second fan blade, and the hinge is hinged to the joint of the shaft arm.

[0013] Furthermore, the dust collection box is located at the lower end of the cooling fan, and the dust collection box is concave. The dust collection box is perpendicularly aligned with the first and second fan blades. The baffles are arranged in an inverted "L" shape, and multiple baffles are arranged inside the dust collection box, with a spacing of 0.5-0.7cm between the baffles.

[0014] Furthermore, a track is provided on the outer side of the output shaft, and the first and second fan blades are arranged in a group and slide inside the track. There are 2-3 groups of the first and second fan blades, and the track is matched accordingly. The first and second fan blades are both arranged in an isosceles trapezoidal shape when viewed from the side.

[0015] Furthermore, the shaft arm is located between the first and second fan blades, with each pair of shaft arms arranged in a group. Each group of shaft arms is arranged in a "V" shape when viewed from above, and the shaft arms are connected to each other by hinges.

[0016] Furthermore, the hinge is configured in three segments, with the shaft arm swinging at an angle through two of the hinge segments respectively.

[0017] Furthermore, the swing assembly also includes a rotary bearing, a lower collar, a connecting rod, a cleaning layer, a convex strip, an upper collar, a lower swing arm, a rotating ball, and an upper swing arm. The rotary bearing rotates at the upper end of the output shaft. The lower collar and the upper collar are rotatably fitted onto the upper end of the rotary bearing. The connecting rod is distributed on both sides of the lower collar. The convex strip slides inside the connecting rod. The cleaning layer is slidably nested at the upper end of the connecting rod. The upper swing arm is located on both sides of the lower end of the upper collar. The rotating ball is hinged to the lower end of the upper swing arm. The lower swing arm swings at the end of the rotating ball away from the upper swing arm.

[0018] Furthermore, the upper end of the rotary bearing extends to the bottom of the circuit board, and a groove is provided at the upper end of the rotary bearing. The groove is arranged in a circular shape, and the upper and lower collars are rotatably fitted on the outside of the groove.

[0019] Furthermore, the lower end of the lower swing arm is located on both sides of the upper end of the lower collar. Both the lower collar and the upper collar are circular. When the rotary bearing rotates 360°, the lower collar rotates upward on the outside of the rotary bearing.

[0020] Furthermore, the protrusions are distributed at the four corners of the cleaning layer, the connecting rods are concave and arranged laterally, the cleaning layer is spaced 1-2cm from the bottom of the circuit board, and the cleaning layer is made of sponge material.

[0021] Furthermore, the lower swing arm is 3-5cm shorter than the upper swing arm, the rotating sphere is the connecting part of the lower swing arm and the upper swing arm, and both the lower swing arm and the upper swing arm are set at an inclination of 5-25°.

[0022] Beneficial effects:

[0023] 1. The microprocessor is connected to the external control terminal via fiber optic cable. The external control terminal transmits data to the microprocessor, which processes the data. The processed data is then transmitted to the circuit board. Since the circuit board is a control circuit board, it transmits signal commands to the external control terminal, enabling this type of computer to perform intelligent control based on big data processing.

[0024] 2. The internal motor of the cooling fan drives the output shaft to rotate. Since there is a track on the outside of the output shaft, the first and second fan blades slide synchronously inside the track. At this time, the first and second fan blades swing in the same direction. Since the length of the track on the outside of the output shaft is limited, when the first fan blade swings to one end of the track on the outside of the output shaft, the side wall of the first fan blade is pressed against the inside of the track and stops. The first fan blade cannot continue to swing on the outside of the output shaft.

[0025] 3. The second fan blade continuously oscillates inside the output shaft track. As the second fan blade slides rapidly, the distance between the second and first fan blades decreases. The shaft arm on the side of the second fan blade swings at an angle through the hinge, thus reducing the angle between the shaft arm on the side of the second fan blade and the shaft arm on the side of the first fan blade. Due to the high rotation speed of the output shaft, the side of the second fan blade rapidly expands to one end of the first fan blade. The vibration generated by the collision between the second and first fan blades helps the dust on the upper part of the second and first fan blades fall downwards. The dust falls downwards into the dust collection box. The baffle inside the dust collection box prevents the dust from splashing upwards again to the outside of the first and second fan blades. This allows the cooling fan to prevent dust from accumulating on the upper part of the first and second fan blades for a long time after startup by using the collision between the first and second fan blades. At the same time, the overall operation of the cooling fan is not affected during dust removal.

[0026] 4. When the output shaft is stationary, the upper and lower collars slide downwards due to their own weight. The upper swing arm supports the lower end of the upper collar, while the lower collar is located at the lower end of the outer groove of the upper end of the rotary bearing. When the output shaft rotates at high speed, the output shaft drives the rotary bearing to rotate synchronously, and the upper and lower collars at the upper end of the rotary bearing rotate and move synchronously. After the upper collar rotates and moves upward briefly, the upper end of the upper collar engages with the inner wall of the outer groove of the rotary bearing.

[0027] 5. The lower collar drives the connecting rod to rotate and move synchronously. When the connecting rod rotates 360° below the circuit board through the lower collar, the output shaft rotates at high speed. Therefore, the connecting rod rotates at high speed above the rotary bearing through the lower collar. The high-speed rotation of the connecting rod generates an upward centrifugal force. The cleaning layer slides upward inside the connecting rod using the upward centrifugal force. At this time, the upper end of the cleaning layer rubs against the electronic components at the lower end of the circuit board for cleaning. When the lower collar moves upward, the lower swing arm tilts upward through the rotating ball. By using the fact that the length of the lower swing arm is 3-5cm shorter than that of the upper swing arm, the upward swing angle of the lower swing arm can be limited, avoiding the lower collar sliding too far upward. The rotation of the output shaft can clean the electronic components at the lower end of the circuit board, preventing dust from adhering to the electronic components at the lower end of the circuit board and affecting the overall use of the circuit board.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Example:

[0040] As attached Figure 1 To be continued Figure 8 As shown:

[0041] Example 1: An industrial intelligent control computer based on big data includes a frame 1. The lower end of the frame 1 is provided with a mounting base 101, and the upper end of the mounting base 101 is provided with a control component. The control component includes a motherboard 102, a microprocessor 103, and a circuit board 107. The microprocessor 103 is located on the upper end of the motherboard 102, and the motherboard 102 and the circuit board 107 are both located inside the frame 1. A cooling fan 104 rotates on the upper end of the motherboard 102, and an output shaft 105 rotates on the upper end of the cooling fan 104. Heat dissipation mesh 106 is provided on both sides of the frame 1.

[0042] Among them: mounting base 101 and frame 1, the mounting base 101 has through bolts inside, and the frame 1 is installed and fixed through the mounting base 101;

[0043] The motherboard 102 is a computer motherboard, and the microprocessor 103 is connected to the circuit board 107 in a loop. The circuit board 107 is a control circuit board. The frame 1 has a socket at one end near the motherboard 102. The socket has a movable nested optical fiber cable. The microprocessor 103 and the circuit board 107 are connected to the external control terminal in a loop through the optical fiber cable.

[0044] The external control terminal is a wireless controller, which can be installed on the surface of industrial equipment.

[0045] Cooling fan 104 has a motor inside, which is connected to circuit board 107. The motor drives output shaft 105 to rotate 360°. The cooling fan 104 has an oscillating component inside and at the top.

[0046] The microprocessor 103 is connected to the external control terminal via a fiber optic cable. The external control terminal transmits data to the microprocessor 103, which processes the data. The processed data is then transmitted to the circuit board 107. Since the circuit board 107 is a control circuit board, it transmits signal commands to the external control terminal, enabling the computer to perform intelligent control based on big data processing through the circuit board 107.

[0047] Example 2: Refer to the attached instruction manual Figure 1-5 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the swing assembly includes a dust collection box 2, a baffle 201, a first fan blade 3, a second fan blade 301, a shaft arm 302, and a hinge 303. The dust collection box 2 is installed inside the main board 102, the baffle 201 passes through the inside of the dust collection box 2, the first fan blade 3 and the second fan blade 301 swing on the outside of the output shaft 105, the shaft arm 302 swings on the side of the first fan blade 3 and the second fan blade 301, and the hinge 303 is hinged to the joint of the shaft arm 302.

[0048] Among them: dust collection box 2 and baffle 201. The dust collection box 2 is located at the lower end of the cooling fan 104. The dust collection box 2 is concave and is perpendicularly corresponding to the first fan blade 3 and the second fan blade 301. The baffle 201 is inverted "L" shape and multiple baffles 201 are arranged inside the dust collection box 2. The baffles 201 are spaced 0.5-0.7cm apart.

[0049] The first fan blade 3 and the second fan blade 301 are provided with a track on the outside of the output shaft 105. The first fan blade 3 and the second fan blade 301 are arranged in a group and slide inside the track. There are 2-3 groups of the first fan blade 3 and the second fan blade 301, and the track is matched with them. The first fan blade 3 and the second fan blade 301 are both arranged in an isosceles trapezoidal shape when viewed from the side.

[0050] The first blade 3 and the second blade 301 are both arranged in an isosceles trapezoidal shape when viewed from the side, which prevents dust from accumulating at the upper part of the first blade 3 and the second blade 301. The isosceles trapezoidal shape can help the dust slide down into the dust collection box 2.

[0051] Shaft arm 302 is located between the first fan blade 3 and the second fan blade 301. Shaft arms 302 are arranged in pairs. Each pair of shaft arms 302 is arranged in a "V" shape when viewed from above. The shaft arms 302 are connected to each other by hinges 303.

[0052] The hinge 303 is configured in three segments, and the shaft arm 302 swings at an angle through two of the segments of the hinge 303.

[0053] The shaft arm 302 swings at an angle through two sections of the hinge 303, which facilitates the shaft arm 302 on the side of the first fan blade 3 and the second fan blade 301 to swing in opposite directions through the hinge 303.

[0054] Wherein: The internal motor of the cooling fan 104 drives the output shaft 105 to rotate. Since the outer side of the output shaft 105 is provided with a track, the first fan blade 3 and the second fan blade 301 slide synchronously inside the track. At this time, the first fan blade 3 and the second fan blade 301 swing in the same direction. Since the length of the track outside the output shaft 105 is limited, when the first fan blade 3 swings to one end of the track outside the output shaft 105, the side wall of the first fan blade 3 is pressed and stationary with the inside of the track, and the first fan blade 3 cannot continue to swing outside the output shaft 105.

[0055] The second blade 301 continuously oscillates inside the track of the output shaft 105. As the second blade 301 slides rapidly, the distance between the second blade 301 and the first blade 3 decreases. The shaft arm 302 on the side of the second blade 301 oscillates at an angle through the hinge 303, thus reducing the angle between the shaft arm 302 on the side of the second blade 301 and the shaft arm 302 on the side of the first blade 3. Due to the high rotational speed of the output shaft 105, the side of the second blade 301 rapidly expands to one end of the first blade 3, utilizing the interaction between the second blade 301 and the first blade 3. The vibration generated by the collision between the fan blades 3 can help the dust on the upper part of the second fan blade 301 and the first fan blade 3 fall downwards. The dust falls downwards into the dust collection box 2. The baffle 201 inside the dust collection box 2 can prevent the dust from splashing upwards again to the outside of the first fan blade 3 and the second fan blade 301. This allows the cooling fan 104 to prevent dust from accumulating on the upper part of the first fan blade 3 and the second fan blade 301 for a long time after starting, by using the collision between the first fan blade 3 and the second fan blade 301. At the same time, the overall operation of the cooling fan 104 is not affected during dust removal.

[0056] Example 3: Refer to the attached instruction manual Figure 6-8 It can be seen that the difference between Embodiment 3 and Embodiments 1 and 2 is that the swing assembly further includes a rotary bearing 4, a lower collar 401, a connecting rod 402, a cleaning layer 403, a protrusion 404, an upper collar 5, a lower swing arm 501, a rotating ball 502, and an upper swing arm 503. The rotary bearing 4 rotates at the upper end of the output shaft 105. The lower collar 401 and the upper collar 5 are rotatably fitted onto the upper end of the rotary bearing 4. The connecting rod 402 is distributed on both sides of the lower collar 401. The protrusion 404 slides inside the connecting rod 402. The cleaning layer 403 slides and is nested at the upper end of the connecting rod 402. The upper swing arm 503 is located on both sides of the lower end of the upper collar 5. The rotating ball 502 is hinged to the lower end of the upper swing arm 503. The lower swing arm 501 swings at the end of the rotating ball 502 away from the upper swing arm 503.

[0057] Among them: the rotary bearing 4, the upper end of the rotary bearing 4 extends to the lower part of the circuit board 107, the upper end of the rotary bearing 4 is provided with a groove, the groove is arranged in a circular shape, and the upper collar 5 and the lower collar 401 are rotatably fitted on the outside of the groove.

[0058] The lower collar 401 and the upper collar 5, the lower end of the lower swing arm 501 are located on both sides of the upper end of the lower collar 401. The lower collar 401 and the upper collar 5 are both arranged in a circular shape. When the rotary bearing 4 rotates 360°, the lower collar 401 moves upward in a rotating manner on the outside of the rotary bearing 4.

[0059] The connecting rod 402 and the cleaning layer 403 are provided. The protrusions 404 are distributed at the four corners of the cleaning layer 403. The connecting rod 402 is concave and arranged horizontally. The cleaning layer 403 is spaced 1-2cm from the lower end of the circuit board 107. The cleaning layer 403 is made of sponge material.

[0060] When the connecting rod 402 rotates 360° below the circuit board 107 via the lower collar 401, the output shaft 105 rotates at high speed, so the connecting rod 402 rotates at high speed above the rotary bearing 4 via the lower collar 401. The high-speed rotation of the connecting rod 402 generates an upward centrifugal force, and the cleaning layer 403 slides upward inside the connecting rod 402 using the upward centrifugal force. At this time, the upper end of the cleaning layer 403 is perpendicular to the electronic components at the lower end of the circuit board 107 for friction cleaning.

[0061] The lower swing arm 501 and the upper swing arm 503 are connected by a lower swing arm 501 and an upper swing arm 503. The lower swing arm 501 is 3-5cm shorter than the upper swing arm 503. The rotating ball 502 is a connecting part of the lower swing arm 501 and the upper swing arm 503. Both the lower swing arm 501 and the upper swing arm 503 are set at an inclination of 5-25°.

[0062] When the lower collar 401 rotates upward, the lower swing arm 501 and the upper swing arm 503 are both set at an angle of 5-25°, and the lower swing arm 501 and the upper swing arm 503 can swing vertically at an angle through the rotating ball 502.

[0063] When the lower swing arm 501 tilts upward through the rotating ball 502, the length of the lower swing arm 501 is 3-5cm shorter than the length of the upper swing arm 503, which can limit the upward swing angle of the lower swing arm 501 and prevent the lower collar 401 from sliding too far upward.

[0064] When the output shaft 105 is stationary, the upper collar 5 and lower collar 401 slide downwards due to their own gravity. The upper swing arm 503 supports the lower end of the upper collar 5, while the lower collar 401 is located at the lower end of the outer groove on the upper end of the rotary bearing 4. When the output shaft 105 rotates at high speed, it drives the rotary bearing 4 to rotate synchronously. The upper collar 5 and lower collar 401 on the upper end of the rotary bearing 4 rotate and move synchronously. After a brief upward rotation, the upper end of the upper collar 5 engages with the inner wall of the outer groove on the rotary bearing 4. (Refer to the attached instruction manual.) Figure 7 As shown;

[0065] The lower collar 401 drives the connecting rod 402 to rotate synchronously. When the connecting rod 402 rotates 360° below the circuit board 107 via the lower collar 401, the output shaft 105 rotates at high speed. Therefore, the connecting rod 402 rotates at high speed above the rotary bearing 4 via the lower collar 401. The high-speed rotation of the connecting rod 402 generates an upward centrifugal force. The cleaning layer 403 uses the upward centrifugal force to slide upward inside the connecting rod 402. At this time, the upper end of the cleaning layer 403 rubs perpendicularly against the electronic components at the lower end of the circuit board 107. During cleaning, when the lower collar 401 moves upward, the lower swing arm 501 tilts and swings upward via the rotating ball 502. Since the length of the lower swing arm 501 is 3-5cm shorter than the length of the upper swing arm 503, the upward swing angle of the lower swing arm 501 can be limited, preventing the lower collar 401 from sliding too far upward. The rotation of the output shaft 105 can clean the electronic components at the lower end of the circuit board 107, preventing dust from adhering to the electronic components at the lower end of the circuit board 107 and affecting the overall use of the circuit board 107.
