[0002] An industrial electronic sensor data processing device is a hardware device that integrates signal conditioning, data conversion, and anti-interference processing functions. Its core function is to receive the raw physical signals collected by industrial sensors, process the signals through mechanical structure and circuit design, and output stable, accurate digital or standard analog signals that meet the requirements of industrial control systems. It is the core intermediate hub between industrial sensors and upper control systems such as PLCs, DCSs, and industrial control computers, and is widely used in highly interference-prone industrial scenarios such as intelligent manufacturing, petrochemicals, metallurgy, and power.

[0003] In practical applications, existing technologies typically involve fixing sensors in specific locations to perform data processing. However, the continuous vibrations generated by mechanical operation and equipment start-up and shutdown can cause loose circuit board solder joints and poor sensor contact over time, indirectly leading to data distortion. To address this, the present invention provides an interference-resistant industrial electronic sensor data processing device. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Specific implementation examples are given below.

[0019] Please see Figure 1-5This invention provides an anti-interference industrial electronic sensor data processing device, including a circuit board 1. All electrical appliances used in this invention are commercially available, and their specific structures and working principles are well-known prior art and will not be described further here. The anti-interference industrial electronic sensor data processing device includes a circuit board 1. A fixing screw 2 is provided on the inner wall of the circuit board 1. A bracket 3 is provided on the lower surface of the circuit board 1, and the bracket 3 is connected to the fixing screw 2. A base 4 is slidably connected to the inner wall of the bracket 3. A spring 5 is provided on the upper surface of the base 4. A bracket 6 is provided on the upper surface of the spring 5, and the bracket 6 is connected to the base 4. A nut 7 is threadedly connected to the outer wall of the base 4, and the nut 7 is connected to the bracket 3. A connecting rod 8 is rotatably connected to the outer wall of the bracket 6. A sliding block 9 is rotatably connected to the inner wall of the connecting rod 8, and the outer wall of the sliding block 9 is slidably connected to... A limiting frame 10 is connected to a base plate 11 fixedly connected to its lower surface. A spring rod 28 is provided on the inner wall of the limiting frame 10, and the spring rod 28 is connected to the sliding block 9. When the whole is subjected to vibration, the vibration can be transmitted from the base 4 to the spring 5 through the base plate 11, thereby buffering the impact force for the first time. After the base 4 transmits the vibration to the bracket 6, the movement of the bracket 6 can drive the connecting rod 8 so that the sliding block 9 can slide in the limiting frame 10. The spring rod 28 provided in the limiting frame 10 can limit the movement trajectory of the sliding block 9, and at the same time, the spring on the spring rod 28 can limit the movement of the sliding blocks 9 on both sides, achieving a secondary buffering effect. Through the above structure, the impact force on the circuit board 1 fixed to the bracket 3 by the fixing screw 2 can be reduced, solving the problem of vibration causing loose circuit board solder joints and poor sensor contact, which indirectly leads to data distortion.

[0020] like Figure 1 and Figure 5 As shown, a sealing strip 12 is slidably connected to the upper surface of the base plate 11, and a shielding cover 13 is provided on the upper surface of the sealing strip 12. An insert block 14 is fixedly connected to the outer wall of the shielding cover 13, and a fixing shell 15 is slidably connected to the outer wall of the insert block 14. The fixing shell 15 is connected to the base plate 11. The insert block 14 on the shielding cover 13 is aligned with the fixing shell 15 and inserted, thereby achieving the effect of fixing the shielding cover 13. The sealing strip 12 can prevent external moisture from entering the shielding cover 13 and causing damage to the circuit board 1.

[0021] like Figure 1 and Figure 3As shown, a fixing frame 16 is fixedly connected to the outer wall of the shielding cover 13. A locking block 17 is slidably connected to the inner wall of the fixing frame 16. A connecting shaft 18 is slidably connected to the inner wall of the locking block 17. A second spring 19 is fixedly connected to the outer wall of the connecting shaft 18. The second spring 19 is connected to the locking block 17. A baffle 20 is fixedly connected to the outer wall of the connecting shaft 18. The baffle 20 is connected to the shielding cover 13. Pressing the fixing frame 16 causes it to slide on the outer wall of the connecting shaft 18, while the second spring 19 undergoes elastic deformation, aligning the locking block 17 with the fixing frame 16. Releasing the locking block 17 allows the second spring 19 to return to its original shape and allows the locking block 17 to be inserted into the fixing frame 16, thereby achieving the effect of quickly installing the baffle 20.

[0022] like Figure 1 and Figure 4 As shown, a bottom shell 21 is provided on the lower surface of the base plate 11, and a fan 22 is fixedly connected to the inner wall of the bottom shell 21. Heat dissipation fins 23 are fixedly connected to the lower surface of the base plate 11. The heat dissipation fins 23 on the lower surface of the base plate 11 can conduct the heat in the shield 13 to the heat dissipation fins 23, thereby reducing the heat accumulation and reducing the lifespan of the circuit board 1. The fan 22 fixed on the bottom shell 21 can dissipate the heat on the heat dissipation fins 23.

[0023] like Figure 1 and Figure 4 As shown, a limiting strip 24 is fixedly connected to the inner wall of the bottom shell 21. A brush block 25 is slidably connected to the inner wall of the limiting strip 24. A threaded rod 26 is threadedly connected to the outer wall of the brush block 25. The threaded rod 26 is connected to the bottom shell 21. A limiting rod 27 is slidably connected to the inner wall of the brush block 25. The limiting rod 27 is connected to the bottom shell 21. Rotating the threaded rod 26 allows the brush block 25 to be driven to slide in the limiting strip 24. The limiting rod 27 restricts the movement trajectory of the brush block 25. The brush block 25 can clean the dust accumulated on the heat dissipation fins 23, thereby preventing the accumulation of dust on the heat dissipation fins 23 from causing a decrease in heat dissipation efficiency.

[0024] like Figure 1 and Figure 3 As shown, the inner wall of the shield 13 is fixedly connected to an interface. The width of the interface is the same as that of the baffle 20. By setting the length of the interface to be the same as that of the baffle 20, it is ensured that the baffle 20 can completely cover the entire interface.

[0025] like Figure 1 and Figure 5 As shown, the shielding cover 13 is a double-layer design. The shielding cover 13 is set as a double-layer structure with an air gap reserved between the two layers, forming a double-layer blocking structure of shielding-air-shielding, thereby improving the anti-interference capability.

[0026] When the device is put into operation, after it is put into operation on site, when the vibration generated by the operation of the surrounding equipment is transmitted to the device body, the technicians can observe that: the base plate 11 can transmit the vibration from the base 4 to the spring 5, thereby buffering the impact force for the first time. After the base 4 transmits the vibration to the bracket 6, the movement of the bracket 6 can drive the connecting rod 8 so that the sliding block 9 can slide in the limiting frame 10. The spring rod 28 set in the limiting frame 10 can limit the movement trajectory of the sliding block 9, and at the same time, it can also limit the movement of the sliding blocks 9 on both sides through the spring on the spring rod 28, achieving a secondary buffering effect. Through the above structure, the impact force on the circuit board 1 fixed to the bracket 3 by the fixing screw 2 can be reduced, solving the problem of vibration causing the circuit board solder joints to loosen, the sensor to have poor contact, and indirectly causing data distortion. During the assembly phase, operators manually insert the insert block 14 on the shielding cover 13 into the fixing shell 15 to secure the shielding cover 13. Technicians check the sealing strip 12 pre-installed on the base plate 11 to ensure it fits tightly against the bottom of the shielding cover 13, effectively preventing external moisture from entering the shielding cover 13 and damaging the circuit board 1. When installing the baffle 20, the operator simply presses the fixing bracket 16 to slide it against the outer wall of the connecting shaft 18, causing the spring 19 to deform elastically. Aligning the locking block 17 with the fixing bracket 16 and releasing the locking block 17 allows the spring 19 to return to its original shape and insert the locking block 17 into the fixing bracket 16, thus achieving quick installation of the baffle 20. During assembly, technicians install heat dissipation fins 23 on the lower surface of the base plate 11, allowing heat from the shielding cover 13 to be conducted to the heat dissipation fins 23, thereby reducing heat buildup and minimizing the lifespan of the circuit board 1. The assembler then installs heat dissipation fins 23 on the base shell 21. The fixed fan 22 can dissipate the heat on the heat sink 23. During daily operation and maintenance, the staff only needs to rotate the threaded rod 26 to drive the brush block 25 to slide in the limit bar 24. The limit bar 27 can restrict the movement trajectory of the brush block 25. The brush block 25 can clean the dust accumulated on the heat sink 23, thereby preventing the heat dissipation efficiency from decreasing due to the accumulation of dust on the heat sink 23. The shielding cover 13 is set as a double-layer structure with an air gap reserved between the two layers, forming a double-layer blocking structure of shielding-air-shielding, thereby improving the anti-interference capability.
