Description

Technical Field

[0001] The present invention relates to an intelligent control box, and in particular to an anti-interference device for lane intelligent node equipment. Background Art

[0003] In order to solve this problem, the current solutions are: Automatic calibration: Perform automatic calibration regularly to correct drift caused by environmental factors. Use reference signals or standard sources to calibrate the system.

[0004] Temperature compensation involves designing temperature compensation algorithms to adjust the measured signal in real time based on temperature changes. Temperature monitoring can be implemented in hardware or software to account for temperature effects in signal processing.

[0005] Error detection and correction, by introducing redundant sensors or using digital signal processing technology to detect abnormal signals, implement real-time error correction, and improve the robustness of the system.

[0006] Isolation and shielding: Reasonably isolate and shield the signal processing circuit to reduce electromagnetic interference.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, an anti-interference device for lane intelligent node equipment includes: A bottom plate 1 with a frame groove 11 on the top; The first side panels 2 are inserted into the opposite ends of the frame groove 11; The second side panels 3 are inserted into the opposite ends of the frame groove 11; The top plate 4 is plugged into the side ends of the first side plate 2 and the second side plate 3 assembled on the bottom plate 1; The first side plate 2 is provided with a plug-in slot 21 for plugging into the end of the second side plate 3; The second side plate 3 is provided with a guide groove 32 connected to the boring grooves 31 formed at opposite ends; A connecting groove 22 is formed at one end of the first side plate 2 to connect the boring grooves 31 on the two second side plates 3 located on the same horizontal plane; A glue guide groove 41 is formed on the top of the top plate 4 and is in communication with the guide groove 32 and is located at the same level as one of the boring grooves 31 .

[0028] Specifically, the first side plate 2, the second side plate 3, the bottom plate 1 and the top plate 4 in the embodiment include glass fiber wool and copper plates arranged on both sides of the glass fiber wool, and the copper plates located on the outside of the anti-interference device are coated with a conductive material.

[0029] Furthermore, the mixed glue in the embodiment is a liquid conductive foam material.

[0030] In the above technology, the mixed glue is poured through the glue guide groove 41, and the entering mixed glue will flow along the guide groove 32 of the first second side panel 3 and enter the boring groove 31 after being filled, so that the mixed glue in the boring groove 31 contacts the inner wall of the plug-in groove 21. As the pouring continues, when the mixed glue fills the boring groove 31 of the first second side panel 3, the mixed glue passes through the connecting groove 22 of the first side panel 2 and enters the boring groove 31 of the second second side panel 3. Then, as the mixed glue continues to be poured, it overflows to the guide groove 32 of the second second side panel 3, thereby forming a complete glue pouring series, so that the joints between the filled first side panel 2, the second side panel 3, the bottom panel 1 and the top panel 4 are combined, and the gap glue pouring method is adopted, which can greatly reduce the outside world.

[0031] As an embodiment further provided by the present invention, arc-shaped parts 411 are symmetrically arranged on the inner wall of the glue guide groove 41, and a clamping channel is formed between the two arc-shaped parts 411. The clamping channel is divided into an elliptical channel 412, a conical channel 413 and a conical channel 414 according to its shape. The conical channel 414 has a narrow mouth and a wide mouth, and the narrow mouth is connected to the conical channel 413.

[0032] Specifically, during the injection process, the mixed rubber is poured through the rubber guide groove 41, first flowing into the elliptical flow channel 412. The mixed rubber then passes through the conical channel 413, where its flow rate is accelerated. Next, the mixed rubber enters the tapered channel 414. Due to the tension, the diffusion surface of the mixed rubber increases, thereby accelerating the injection of the mixed rubber, effectively preventing the formation of bubbles during the injection process, and ensuring smooth injection.

[0033] As another embodiment of the present invention, a partition plate 5 is fixedly mounted within the bore 31, dividing the bore 31 into a flow chamber and a fusion chamber. The flow chamber communicates with the wide opening of the tapered channel 414. The partition plate 5 is provided with a plurality of equally spaced diversion holes 51, with each row of two diversion holes 51. It should be noted that the diversion holes 51 are arc-shaped.

[0034] Specifically, the boring groove 31 in the embodiment is divided by the partition 5 to form a liquid flow cavity and a fusion cavity, and the space of the fusion cavity is half of the liquid flow cavity. When the mixed glue flows along the guide groove 32 and enters the boring groove 31 after being filled, it will enter the liquid flow cavity and then begin to fill the liquid flow cavity. During this process, the mixed glue will enter the fusion cavity through the guide waist hole 51. Due to the arc structure of the guide waist hole 51, the mixed glue will enter the fusion cavity in a vortex form after entering the fusion cavity. The mixed glue entering the fusion cavity cannot fill the entire fusion cavity, but it can fill the liquid flow cavity. The purpose is to form two insulating material layers: one is the multi-faceted structure of the mixed glue after solidification in the fusion cavity, and the other is the mixed glue after solidification that is completely filled into the liquid cavity.

[0035] The mixed glue entering the fusion cavity will come into contact with the inserting groove 21 of the first side panel 2, so that the second side panel 3 and the first side panel 2 are bonded together.

[0036] As another embodiment further provided by the present invention, a centrally arranged guide rod 6 is provided in the liquid flow cavity. The cross section of the guide rod 6 is a V-shaped structure, and the end of the V-shaped structure faces the glue guide groove 41.

[0037] Specifically, in the embodiment, when the mixed rubber is poured into the rubber guide groove 41, the mixed rubber flows along the guide groove 32 of the first second side plate 3 and enters the boring groove 31 after being filled. When entering the boring groove 31, the mixed rubber accumulated on the guide rod 6 will form a liquid head due to the guidance of the guide rod 6, and then begin to flow down under its own weight. During the downward flow, the connection between the liquid head and the rest of the mixed rubber becomes slender, thereby forming a drainage effect, and the rest of the mixed rubber is carried along by the liquid head during the downward flow.

[0038] As another embodiment further provided by the present invention, a boring hole 23 is provided on the first side plate 2 and is arranged opposite to the connecting groove 22. The boring hole 23 is used to connect the guide grooves 32 on the two second side plates 3. There are two groups of boring holes 23, which correspond to the two connecting grooves 22 respectively, so that the connecting grooves 22, boring holes 23 and two boring grooves 31 located on the same horizontal plane form a series circuit; Furthermore, a flow blocker 24 is provided on the boring hole 23 and is distributed close to the glue guiding groove 41 , so that the mixed glue injected into the glue guiding groove 41 enters the liquid flow cavity of a coaxial guiding groove 32 .

[0039] Specifically, in the embodiment, a flow blocking member 24 is provided on the boring hole 23 and is distributed close to the glue guide groove 41. Figure 5As can be seen, when the mixed glue is poured into the glue guide groove 41, the mixed glue is squeezed into the glue guide groove 41 due to the extrusion force, and then blocked by the flow blocking member 24. It then only enters the flow guide groove 32. After the flow guide groove 32 is filled, it enters the boring groove 31 on the second side plate 3 on the horizontal plane where the glue guide groove 41 is located. Therefore, when the mixed glue enters the liquid flow cavity, the air squeezed out by the pouring of the mixed glue will pass through the boring hole 23 and mix with the mixed glue poured from the glue guide groove 41. Therefore, the solidified mixed glue in the liquid flow cavity also has a porous structure and an irregular shape.

[0040] As another embodiment further provided by the present invention, a plurality of equally spaced guide members 7 are provided on the inner walls on opposite sides of the liquid flow chamber. The guide members 7 are divided into an outer arc structure 71 and an inner arc structure 72 according to the structure. The outer arc tops of the two inner arc structures 72 are arranged close to the guide rod 6.

[0041] Specifically, in the embodiment, the guide member 7 in the boring groove 31 of the first second side panel 3 and the guide member 7 in the boring groove 31 of the second second side panel 3 on the horizontal plane of the glue guide groove 41 face opposite directions. Because the mixed glue is poured through the glue guide groove 41, the entering mixed glue will flow along the guide groove 32 of the first second side panel 3 and enter the boring groove 31 after being filled. At this time, the mixed glue moves downward. When the mixed glue fills the boring groove 31 of the first second side panel 3, it will pass through the connecting groove 22 of the first side panel 2 and enter the boring groove 31 of the second second side panel 3. When the mixed glue is filled, it will overflow into the guide groove 32 of the second second side panel 3 as the mixed glue continues to be poured.

[0042] The guide member 7 in the embodiment is used to guide the mixed glue downward quickly under the guidance of the guide rod 6, and then the liquid head will accumulate in the space between the two outer arc structures 71, and with the squeezing force provided by the subsequent mixed glue, the liquid head will enter the inner arc structure 72, and the liquid head will enter the inner arc structure 72. Figure 4 As shown, the space between the two inner arc structures 72 is fan-shaped, so after entering, it will adhere to the inner arc structure 72 under the tension of the hydraulic pressure and then expand into a fan shape, thereby forming a certain pulling force on the mixed glue in the space between the two outer arc structures 71, thereby accelerating the mixed glue to fill the space between the inner arc structures 72.

[0043] The guide waist hole 51 in the embodiment is located in the space between the two outer arc structures 71, so the liquid head will accumulate in the space between the two outer arc structures 71. As the subsequent mixed glue enters, the mixed glue will enter the fusion cavity through the guide waist hole 51.

[0044] As another embodiment further provided by the present invention, the guide member 7 is divided into a first guide member and a second guide member according to the connection mode. The number of the first guide member is one and it is fixedly installed at the end of the liquid flow chamber. A guide wire 73 is provided on the inner arc surface of the outer arc structure 71 of the second guide member close to the inner arc structure 72; Ends of the guide wires 73 on the two second guide members of the same stage are close to each other and extend to between the outer side surfaces of the inner arc structures 72 of the two second guide members / two first guide members of the upper stage.

[0045] Specifically, in the embodiment, only the outer arc structure 71 on the second guide member is provided with a guide wire 73, and then the guide wire 73 will extend into the fan-shaped space between the two inner arc structures 72. The liquid head will accumulate in the space between the two outer arc structures 71, and with the extrusion pressure provided by the subsequent mixed glue, the liquid head will be subjected to the tension of the hydraulic pressure after entering the inner arc structure 72, and will adhere to the inner arc structure 72 and then expand into a fan shape, thereby forming a certain pulling force on the mixed glue in the space between the two outer arc structures 71, thereby accelerating the mixed glue to fill the space between the inner arc structures 72, and during the filling process, it will be drained downward by the guide wire 73, combined with Figure 4 It can be seen that the two guide wires 73 are conical, that is, when the mixed glue is pulled along the guide wire 73, it will be pulled into a fan shape again due to tension, thereby accelerating the flow of the mixed glue and speeding up the liquid head of the second guide member of the next level to accumulate in the space between the two outer arc structures 71.

[0046] As another embodiment further provided by the present invention, wedge-shaped guide blocks 8 are fixedly provided on the inner walls of the opposite sides of the liquid flow chamber, and the second guide member is slidably provided on the wedge-shaped guide blocks 8.

[0047] Furthermore, a tension spring 9 is fixedly provided on the inner wall of the liquid flow chamber, one end of which is connected to the second guide member and keeps the second guide member at a high position of the wedge-shaped guide block 8, so that the distance between the two second guide members of the same level is minimized and they are distributed close to the two second guide members / two first guide members of the upper level.

[0048] Specifically, in this embodiment, as the mixed adhesive flows along the guide wire 73, it is pulled into a fan-shaped shape again due to tension, thereby accelerating the flow of the mixed adhesive and increasing the speed at which the liquid head of the next-level second guide member accumulates in the space between the two outer arc-shaped structures 71. As the accumulation of mixed adhesive increases in the space between the two outer arc-shaped structures 71, the weight of the entire second guide member increases, causing it to move downward under its own weight, causing the tension spring 9 to deform. During this downward movement, a water film is formed due to the tension. This water film formation causes the liquid to flow rapidly, creating a suction-like effect, thereby drawing the mixed adhesive in the previous-level guide member 7 downward, thereby accelerating the flow rate.

[0049] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
