Description

Technical Field

[0001] This application belongs to the field of intelligent traffic light technology, specifically relating to an anti-interference digital-electrical simultaneous transmission and control unit. Background Technology

[0002] The widespread application of artificial intelligence in various industries has also had a significant impact on the general public. In the transportation sector, for example, intelligent traffic light systems use radar and AI cameras installed at intersections to monitor the number of vehicles, distances between vehicles, and vehicle speeds in real time. They also monitor the number of pedestrians and external weather conditions, dynamically adjusting traffic light signals to improve traffic flow at intersections, reduce the idle time of traffic lights, and ultimately improve the carrying capacity of roads.

[0003] In an intelligent traffic light system, monitoring information is fed back to the system based on the problem to be addressed, and the system then adjusts the traffic lights accordingly. Therefore, intelligent traffic light systems typically include a memory and a processor. The memory and processor collect and store necessary road condition information, and the processor dynamically adjusts the traffic light signals. These components are usually installed in a control box, equipped with a communication power supply and network ports for wiring connections.

[0004] In the existing technology, there is an intelligent traffic light control system that integrates the memory and processor in the same control box. To ensure the stable and normal operation of the control system, a voltage regulator is also set up. However, due to the limited volume of the control box, the installation layout of the voltage regulator is limited. Improper installation of the voltage regulator may cause interference to the processor and affect the processor's regulation. Utility Model Content

[0005] This application provides an anti-interference digital-to-electrical simultaneous transmission and control unit that solves the problem of voltage regulator interference to the processor and memory.

[0006] The technical solution adopted in this application is as follows:

[0007] An anti-interference digital-electric simultaneous transmission and control unit includes a control box, which has a housing and a cover that fits over the housing. The housing contains a memory, a processor, and a traffic light control program stored in the memory and capable of running on the processor. The cover contains a voltage regulator.

[0008] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission and control unit, the enclosure includes a first mounting part with a memory and a second mounting part with a processor, and the cover includes a third mounting part with a voltage regulator. The first mounting part and the third mounting part are axially offset.

[0009] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission controller, the enclosure further includes a clearance zone located away from the first mounting part, and when the cover is closed on the enclosure, the voltage regulator is located in the clearance zone.

[0010] In a preferred embodiment of an anti-interference digital-electrical simultaneous transmission and control unit, the first mounting part is located above the second mounting part, the third mounting part is located in the lower half of the cover, and the third mounting part is provided with a metal partition located above the voltage regulator.

[0011] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission controller, when the cover is closed, a clearance gap is formed between the metal partition and the memory.

[0012] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission controller, the voltage regulator is provided with a heat dissipation baffle on its exterior, and the bottom of the enclosure is provided with a through hole connecting to the clearance area. When the cover is closed on the enclosure, the heat dissipation baffle is located in the clearance area.

[0013] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission controller, the heat dissipation partition includes a number of heat dissipation holes.

[0014] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission controller, the voltage regulator includes a positioning plate connected to a cover. The cover has positioning holes, and the positioning plate is fixed to the positioning holes by fasteners.

[0015] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission controller, a shock-absorbing pad is provided between the positioning plate and the cover.

[0016] In a preferred implementation of an anti-interference digital-electrical simultaneous transmission and control unit, the voltage regulator is provided with a metal shielding chamber, the chamber is grounded, and the output cable of the voltage regulator is led out after being filtered by a feedthrough capacitor or a magnetic ring.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] (1) This application integrates the memory and processor within the same control box, facilitating assembly and maintenance by staff. The memory receives and stores acquired information, while the processor issues control commands based on the information stored in the memory, adjusting traffic lights according to road condition information. A voltage regulator is also installed in the control box to ensure stable power supply for the memory and processor. By placing the memory and processor within the box and the voltage regulator within the cover, integrating all three within the control box and fixing them within the box and cover, the voltage regulator and the memory / processor are separated into distinct areas. This avoids excessive concentration of the voltage regulator and the memory / processor, preventing electromagnetic interference from the voltage regulator. Furthermore, this separate area arrangement facilitates troubleshooting and reduces maintenance time.

[0019] (2) By dividing the mounting area into a first mounting section, a second mounting section, and a third mounting section, the assembly positions of the memory, processor, and voltage regulator are clearly partitioned. Furthermore, the first mounting section and the third mounting section are axially offset. It can be understood that the axial direction here refers to the connection between the casing and the cover when the cover is opened and unfolded. By installing the memory and the voltage regulator in this way, the distance between the voltage regulator and the memory is further increased. After the cover is closed, due to the axial offset between the two, the voltage regulator and the memory can still maintain a distance, which helps to avoid strong electrical interference from the voltage regulator to the memory.

[0020] (3) By setting up a clearance zone, the voltage regulator is installed in a designated area. When the cover is closed, the voltage regulator is located within the clearance zone. The placement of the voltage regulator in the control box is partitioned from other components, thus preventing collisions between the voltage regulator and the processor when the cover is closed, and ensuring partitioned assembly of the voltage regulator with the memory and processor. At the same time, the layered arrangement of the first, second, and third mounting parts makes reasonable use of the control box space to achieve vertical partitioning after the cover is closed, reducing noise coupling, achieving noise isolation, and facilitating layered routing of power lines, reducing crosstalk.

[0021] (4) By setting a metal partition in the third mounting part, when the cover is closed, since the first mounting part is located above and the third mounting part is located below, the metal partition separates the third mounting part from the first mounting part, and the clearance between the metal partition and the memory strengthens the safe distance between the memory and the voltage regulator, which helps to avoid electromagnetic interference from the voltage regulator to the memory.

[0022] (5) By setting heat dissipation baffles and heat dissipation holes, the shape of the heat dissipation holes is not limited. Since the voltage regulator is in the clearance area after the cover is closed, and preferably, there is a gap between the voltage regulator and the inner wall of the box, the heat is dissipated from the through hole below through the clearance area, optimizing heat dissipation and avoiding the high temperature of the voltage regulator from affecting the stability of the surrounding components.

[0023] (6) Fix the voltage regulator by setting fasteners and set shock-absorbing pads to prevent the voltage regulator vibration from being transmitted through the cover.

[0024] (7) When the voltage regulator is working, it generates high-frequency electromagnetic noise. Since it shares the same space with the processor and memory, it may affect sensitive circuits through near-field coupling or radiation interference. Setting up an independent metal shielding enclosure can effectively block the propagation path of electromagnetic waves and reduce the interference of the voltage regulator on digital circuits. At the same time, it can act as a Faraday cage to absorb and export high-frequency noise, reducing radiation. Attached Figure Description

In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0036] This application provides an interference-resistant digital-electrical simultaneous transmission and control unit, such as... Figures 1 to 3 As shown, the digital-electric simultaneous transmission control unit includes a control box 1. The control box 1 has a box body 100 and a cover 200 that covers the box body 100. The box body 100 has a memory 300, a processor 400 and a traffic light control program stored in the memory 300 and that can run on the processor 400. The cover 200 has a voltage regulator 500.

[0037] This application integrates the memory 300 and processor 400 within the same control box 1, facilitating assembly and maintenance by personnel. The memory 300 receives and stores acquired information, while the processor 400 issues control commands based on the information from the memory 300, adjusting traffic lights according to obtained road condition information. Simultaneously, a voltage regulator 500 is installed in the control box 1 to ensure stable power supply for the memory 300 and processor 400 for normal operation. The memory 300 and processor 400 are housed in the enclosure 100, and the voltage regulator 500 is housed in the cover 200. These three components are integrated into the control box 1 and distributed and fixed within the enclosure 100 and cover 200, achieving regionalized placement of the voltage regulator 500, memory 300, and processor 400. This avoids excessive concentration of the voltage regulator 500 with the memory 300 and processor 400, thus preventing electromagnetic interference from the voltage regulator 500.

[0038] In addition, setting up separate zones facilitates troubleshooting and reduces repair time.

[0039] In one embodiment, such as Figure 3 As shown, the housing 100 includes a first mounting part 101 with a memory 300 and a second mounting part 102 with a processor 400, and the cover 200 includes a third mounting part 201 with a voltage regulator 500. The first mounting part 101 and the third mounting part 201 are axially offset.

[0040] By dividing the mounting area into a first mounting section 101, a second mounting section 102, and a third mounting section 201, the assembly positions of the memory 300, processor 400, and voltage regulator 500 are clearly partitioned. Furthermore, the first mounting section 101 and the third mounting section 201 are axially offset. This axial offset refers to the axis between the housing 100 and the cover 200 when the cover 200 is opened and unfolded. This offset mounting of the memory 300 and voltage regulator 500 further increases the distance between them. Even after the cover 200 is closed, the axial offset ensures that the voltage regulator 500 and memory 300 remain spaced apart, which helps prevent strong electrical interference from the voltage regulator 500 to the memory 300.

[0041] Furthermore, the enclosure 100 also includes a clearance area 103 located away from the first mounting part 101, and when the cover 200 is closed on the enclosure 100, the voltage regulator 500 is located in the clearance area 103.

[0042] By setting up a clearance zone 103, the voltage regulator 500 is installed in a designated area. When the cover 200 is closed, the voltage regulator 500 is located within the clearance zone 103. This partitioning of the voltage regulator 500's position within the control box 1 from other components prevents collisions between the voltage regulator 500 and the processor 400 when the cover 200 is closed to the box 100, and ensures partitioned assembly of the voltage regulator 500 with the memory 300 and the processor 400. Simultaneously, the layered arrangement of the first mounting part 101, the second mounting part 102, and the third mounting part 201 rationally utilizes the space of the control box 1 to achieve vertical partitioning after the cover is closed, reducing noise coupling, achieving noise isolation, and facilitating layered power cable routing, thus reducing crosstalk.

[0043] In addition, such as Figure 1 As shown, when the processor 400 is installed, there is a certain distance between its outer wall and the opening end of the housing 100, that is, the thickness of the processor 400 is less than the thickness of the housing 100. When the lid is closed, this part can also form a partial clearance area 103. When the voltage regulator 500 extends into the housing 100, this part provides a certain clearance space for the voltage regulator 500.

[0044] In one embodiment, the first mounting part 101 is located above the second mounting part 102, and the third mounting part 201 is located in the lower half of the cover 200. The third mounting part 201 is provided with a metal partition 202 located above the voltage regulator 500.

[0045] Furthermore, when the cover 200 is closed, a clearance gap is formed between the metal partition 202 and the memory 300.

[0046] By providing a metal partition 202 in the third mounting part 201, when the cover 200 is closed, since the first mounting part 101 is located above and the third mounting part 201 is located below, the metal partition 202 separates the third mounting part 201 from the first mounting part 101. The clearance between the metal partition 202 and the memory 300 strengthens the safe distance between the memory 300 and the voltage regulator 500, which helps to avoid electromagnetic interference from the voltage regulator 500 to the memory 300.

[0047] Preferably, the voltage regulator 500 is provided with a heat dissipation baffle 203 on the outside, and the bottom of the housing 100 is provided with a through hole 104 that connects to the clearance area 103. When the cover 200 is closed on the housing 100, the heat dissipation baffle 203 is located in the clearance area 103.

[0048] Furthermore, the heat dissipation partition 203 includes a number of heat dissipation holes 204.

[0049] By setting the heat dissipation baffle 203 and the heat dissipation hole 204, the shape of the heat dissipation hole 204 is not limited. Since the voltage regulator 500 is in the clearance area 103 after the cover 200 is closed, and preferably, there is a gap between the voltage regulator 500 and the inner wall of the box 100, the heat is dissipated from the through hole 104 below through the clearance area 103, thereby optimizing heat dissipation and preventing the high temperature of the voltage regulator 500 from affecting the stability of the surrounding components.

[0050] It is understandable that the positions of the first mounting part 101, the second mounting part 102 and the third mounting part 201 are indicated by dashed lines in the figure. In actual assembly, in order to meet the installation of components of different specifications, it is not necessary to use baffles or other means to clearly isolate the mounting parts within the housing 100.

[0051] In one embodiment, such as Figure 1 As shown, the voltage regulator 500 includes a positioning plate 205 connected to the cover 200. The cover 200 has positioning holes, and the positioning plate 205 is fixed to the positioning holes by fasteners. A shock-absorbing pad is provided between the positioning plate 205 and the cover 200. The voltage regulator 500 is fixed by fasteners, and the shock-absorbing pad prevents vibration of the voltage regulator 500 from being transmitted through the cover 200.

[0052] Understandably, fasteners such as screws, which are commonly used in existing technologies, can be selected to secure the housing of the voltage regulator 500.

[0053] In one embodiment, the voltage regulator 500 is externally equipped with a metal shielding chamber, the chamber being grounded, and the output cable of the voltage regulator 500 is led out after being filtered by a feedthrough capacitor or a magnetic ring. This embodiment is not shown in the figure. In practical applications, the metal shielding chamber can be configured by those skilled in the art based on the installation position of the voltage regulator 500 in the control box 1.

[0054] The voltage regulator 500 generates high-frequency electromagnetic noise during operation. Sharing the same space with the processor 400 and memory 300, it may affect sensitive circuits through near-field coupling or radiated interference. Setting up an independent metal shielding enclosure can effectively block the propagation path of electromagnetic waves, reducing the interference of the voltage regulator 500 on digital circuits. Simultaneously, it can act as a Faraday cage, absorbing and dissipating high-frequency noise, thus reducing radiation.

[0055] It is understood that the housing 100 and cover of the control box 1 can be connected by hinges or other common housing 100 connection methods in the prior art.

[0056] Furthermore, if the shielding of control box 1 is inadequate, the electromagnetic noise of voltage regulator 500 may radiate to the outside, or external interference (such as radio or motor noise) may enter the box, affecting system stability. In one embodiment, the outer casing of control box 1 is made of conductive metal, such as aluminum alloy or galvanized steel plate. The metal casing can form a Faraday cage effect, confining interference within the box or blocking external noise.

[0057] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0058] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0059] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
