Description

Technical Field

[0001] This utility model belongs to the field of electrical engineering, and in particular relates to an Internet of Things (IoT) lighting control system and device. Background Technology

[0002] Traditional street light control has evolved through five generations, from manual switch operation, microcomputer time controllers, and geodetic light controllers to remote centralized control. Early centralized systems based on loop control (such as unified switching via distribution boxes) struggled to achieve refined management, and fault diagnosis relied on manual inspections, resulting in low response efficiency. With the development of IoT technology, single-lamp control systems gradually became widespread after 2010. By installing intelligent modules on each street light, "point-to-point" monitoring was achieved, significantly improving fault location accuracy and maintenance efficiency.

[0003] However, existing single-lamp control systems use a control center to send commands (such as switching, dimming, and timer control commands) to streetlights via wired / wireless means. The data that streetlights can transmit is too limited, only transmitting a portion of the input information and unable to transmit environmental parameters such as light intensity, temperature, and humidity in real time. As a result, existing technologies can only transmit limited data, which cannot meet the needs of comprehensive monitoring and refined management of the streetlight operating environment.

[0057] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art:

[0058] This invention can receive signals from an external system platform via a communication unit and control the opening, closing, and dimming of the light source module via a control module. It can also detect circuit information via a metering module and transmit it to the system platform via the communication unit, thereby enabling the detection, display, and application of data such as circuit voltage, current, internal resistance, and light source module brightness.

[0059] This invention features a wiring cavity on the side of the power supply cavity with built-in wiring terminals, which eliminates the need for the power supply input and output lines to be directly fixed to the power board inside the power supply cavity. The input and output lines can be disassembled and replaced as needed, supporting replacement of any line length and the use of cables with different safety standards from different countries.

[0060] The top of the wiring cavity has an opening for inserting terminals and plugging / unplugging wires. A detachable top cover is installed at this opening, which fits tightly against the inner wall of the wiring cavity, making installation very convenient. The top cover also has a caulking hole, allowing for the application of sealant to achieve a waterproof seal after the top cover is fixed, preventing issues such as incomplete sealant application.

[0061] There are multiple terminals, and the power input and output lines are connected to different terminals to avoid electromagnetic compatibility issues. Adjacent terminals are separated by partitions with notches to facilitate glue application.

[0062] The terminal block has a protrusion on its outer side and a corresponding slot inside the wiring cavity. The protrusion can be inserted into the slot for an interference fit to achieve a fixed position. By fixing the terminal block inside the wiring cavity, the terminal block is less likely to wobble when inserting or removing wires, making insertion and removal more convenient and less likely to affect the structure of the terminal block itself.

[0063] This invention detachably mounts the communication unit to the side wall or top surface of the housing, and electrically connects it to the internal circuitry via connecting wires or terminals. By placing the communication unit outside the housing, it effectively isolates it from the high-temperature environment and potential electromagnetic radiation sources generated during the operation of the internal circuitry, thus significantly reducing the temperature impact and electromagnetic interference on the communication unit. This design ensures the stability and reliability of the communication unit, reduces communication failures caused by environmental factors, and improves communication quality and operational efficiency.

[0064] The communication unit is fixed to the side wall of the IoT driver via a hook-and-loop structure, eliminating the need for other external fixing or positioning components and facilitating its assembly and disassembly. In addition to the hook-and-loop structure, the communication unit also features through-holes for screw insertion for secure mounting. The communication unit can be mounted on the IoT driver or directly fixed inside the electrical cavity by screwing it into the through-holes, depending on the requirements of different electrical cavities.

[0065] Furthermore, since the communication module is external to the outer casing and can be detached, users can choose to add or remove the communication module according to their needs.

[0066] This utility model is equipped with an auxiliary source metering module and an auxiliary source output module, which can be compatible with other external devices to obtain more comprehensive environmental information and provide corresponding information for the overall control of the external system platform.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0092] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0093] The present invention provides a detailed description of an Internet of Things (IoT) lighting control system and device, in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims.

[0094] Example

[0095] See Figure 1 and Figure 21 This embodiment provides an Internet of Things (IoT) lighting control system, which mainly includes: a power supply module, a light source module (LED light source), a control module (MCU), a communication unit, and a metering module.

[0096] Specifically, such as Figure 1As shown, the power supply module includes an AC / DC unit, a first DC / DC unit, and a second DC / DC unit. The AC / DC unit is connected to the mains power supply and converts the received mains power into a DC bus voltage. The first DC / DC unit and the second DC / DC unit are connected in parallel to the bus extending from the AC / DC unit. The first DC / DC unit is also electrically connected to the light source module to supply power, and the second DC / DC unit is also electrically connected to the control module to supply power.

[0097] Furthermore, the control module is connected to both the communication unit and the metering module via signals. The communication unit and the control module work together to connect to an external system platform, receiving and transmitting signals. The metering module acquires the circuit's detection information and uploads it to the external system platform via the control module and the communication unit.

[0098] To obtain circuit detection information, in this embodiment, the metering module includes an input metering module and an output metering module. The input metering module is electrically connected to the input terminal of the AC / DC unit and is used to detect the voltage and current information flowing through it, i.e., to detect whether the mains power is abnormal. When the AC / DC unit shuts off the mains power supply, the input metering module can detect whether the AC power consumption is close to 0, thus determining whether there is a risk of leakage. The output metering module is electrically connected to both the first DC / DC unit and the light source module, and is used to detect the voltage and current information flowing through it, further determining whether the light source module is working properly. Specifically, the control module detects whether any abnormality has occurred in this embodiment based on the voltage and current information from the input and output metering modules.

[0099] Preferably, this embodiment also includes a temperature detection module (NTC) electrically connected to the control module, used to detect the temperature in this example and upload the temperature detection signal to the control module.

[0100] In addition, a surge protection unit (SPD) to limit voltage and an anti-electromagnetic interference (EMI) unit are provided between the input metering module and the AC / DC unit. An output protection unit to protect the light source module is provided between the output metering module and the light source module. A communication protection unit to protect the communication signal is provided between the control module and the communication unit.

[0101] Preferably, this embodiment can also be connected to an auxiliary source, such as a camera, temperature sensor, light sensor, or other sensors for detecting environmental information. The environmental information captured by the auxiliary source can also be transmitted to an external cloud platform through the communication unit. In this embodiment, an auxiliary source metering module and an auxiliary source output module are provided. The auxiliary source metering module is electrically connected to the second DC / DC module and is used to detect the current and voltage information of the auxiliary source output module. The auxiliary source output module is electrically connected to the auxiliary source metering module and is used as an auxiliary power supply.

[0102] Furthermore, the aforementioned power supply module, control module, metering module, and temperature detection module are all integrated onto the circuit board and housed within the same housing 1. By merging multiple modules and housing them within the same housing 1, the efficiency of mains power supply is improved, the onboard PCB traces are shorter, the internal resistance is lower, and the loss is smaller. The housing 1 can be effectively grounded and shielded from signals such as static electricity.

[0103] For a better option, see Figure 2 This embodiment also provides an Internet of Things lighting control device, including the housing 1 described above and a communication unit 2 integrated with a communication unit.

[0104] The housing 1 contains a power supply cavity 11 and a wiring cavity 12, which are adjacent to each other and separated by a first partition 13. The first partition 13 has a wire-through hole 14, allowing the power supply cavity 11 and the wiring cavity 12 to communicate with each other. A power board 111 is housed within the power supply cavity 11, integrating a power supply module, a control module, a metering module, and a temperature detection module. A terminal block 121 is located within the wiring cavity 12. The connecting wires of the power board 111 are detachably connected to the terminal block 121 via the wire-through hole 14. The terminal block 121 can also be detachably connected to input lines 15 and output lines 16 for connecting other external components. These input lines 15 and output lines 16 can be power supply input lines and output lines, or they can be waterproof lines for connecting communication units.

[0105] Communication unit 2 is connected to the outside of housing 1 and is detachably connected to housing 1. Communication unit 2 is electrically connected to terminal 121 via corresponding input line 15.

[0106] See Figure 2 and Figure 3 Specifically, the wiring cavity 12 is located beside the power supply cavity 11 and contains a wiring terminal 121, so that the input line 15 and the output line 16 do not need to be directly fixed to the power board 111 inside the power supply cavity 11. Previously, because the output line 16 and the input line 15 were fixed to the power board 111, there were hundreds of types of control devices to meet different wire material and length requirements, making inventory and management very difficult. In this embodiment, by adding the wiring cavity 12 and the wiring terminal 121, the input line 15 and the output line 16 can be disassembled and replaced as needed, supporting the replacement of wires of any length and specification. Therefore, only the same embodiment needs to be used, and the corresponding wires need to be replaced for compatibility.

[0107] Further, see Figure 2 and Figure 4In this embodiment, the top of the wiring cavity 12 has an opening for inserting the terminal block 121 and plugging / unplugging the wire. A removable top cover 17 is provided at the opening, and the top cover 17 is interference-fitted with the inner wall of the wiring cavity 12. Specifically, several slots 123 are provided on the inner wall of the wiring cavity 12, and several downward protrusions 171 are provided on the periphery of the top cover 17. When the top cover 17 is installed, the protrusions 171 are inserted into the corresponding slots 123 and are interference-fitted with the slot walls, making installation very convenient. In addition, to facilitate the insertion of the protrusions 171, a groove is provided at the bottom of the protrusions 171 to facilitate deformation. Preferably, the top cover 17 also has a through-hole for applying glue 172. When the top cover 17 is installed in the opening, glue is injected into the wiring cavity 12 through the glue hole 172 to achieve waterproof sealing. This prevents the problem of incomplete glue application when applying glue before covering the top cover 17. By applying adhesive, the IoT lighting control device of this embodiment can achieve a waterproof sealing rating of IP68.

[0108] See Figure 2 and Figure 5 To avoid electromagnetic compatibility issues, this embodiment uses multiple terminals 121, with the input line 15 and output line 16 connected to different terminals 121. Furthermore, a second partition 124 is provided within the wiring cavity 12, dividing the interior of the cavity 12 into a first cavity and a second cavity, thus isolating adjacent terminals 121. For ease of potting, a notch 125 is provided in the second partition 124, allowing communication between the first and second cavities.

[0109] Further, see Figure 5 The terminal block 121 is detachably connected to the wiring cavity 12. A protrusion 126 is provided on the outer side of the terminal block 121, and a corresponding slot 127 is provided inside the wiring cavity 12. The protrusion 126 is inserted into the corresponding slot 127 to achieve an interference fit and fixation. By fixing the terminal block 121 inside the wiring cavity 12, the terminal block 121 is less prone to shaking when inserting or removing wires, making insertion and removal more convenient. Furthermore, by providing a protrusion on the outer side of the terminal block 121 to engage with the slot 127 for fixation, the structure of the terminal block 121 is less likely to be affected during insertion and removal. It is easy to understand that the terminal block 121 is made of plastic, and an interference fit could easily cause cracks, affecting its performance. Similarly, to facilitate smooth insertion of the protrusion 126 into the slot 127, a groove is provided at the bottom of the protrusion 126.

[0110] More preferably, see Figures 15 to 20This embodiment provides another implementation method, specifically: its overall structure remains unchanged, the power supply cavity 11 and the wiring cavity 12 are isolated by a first partition 13, and the first partition 13 is provided with a partition through hole 141 near the bottom surface of the outer shell 1, so that the power supply cavity 11 and the wiring cavity 12 are connected in space.

[0111] For a better option, see Figure 15 A power board 111 is placed inside the power supply cavity 11. A wiring portion 129 protrudes from one side of the power board 111. The wiring portion 129 passes through a partition through-hole 141 and is placed inside the wiring cavity 12. Several terminals 121 are installed on the wiring portion 129. The terminals 121 are detachably connected to input lines 15 and output lines 16 for connecting other external components. These input lines 15 and output lines 16 can be power supply input lines 15 and output lines 16, or they can be waterproof lines for connecting a communication module.

[0112] Because the power supply cavity 11 has a wiring cavity 12 on its side and a built-in terminal block 121, the power input line 15 and output line 16 do not need to be directly fixed to the power board 111 inside the power supply cavity 11. The input line 15 and output line 16 can be disassembled and replaced as needed, supporting replacement of any line length and supporting replacement of cables with different safety standards from different countries. Compared with placing the terminal block 121 inside the wiring cavity 12 and connecting it to the power board 111 through the partition through hole 141, this structure eliminates the internal wiring operation, making installation very convenient, time-saving and labor-saving.

[0113] Further, see Figure 16 and Figure 17 To facilitate the passage of the wiring portion 129 and the wiring terminal 121 on the power board 111 through the partition through hole 141, the height of the partition through hole 141 is greater than the thickness of the power board 111 plus the height of the wiring terminal 121, based on the inner bottom surface of the outer casing 1. Furthermore, to achieve a seal in the power cavity 11, glue is applied inside the power cavity 11. However, due to the presence of the partition through hole 141, the glue may overflow the wiring terminal 121, preventing the subsequent insertion of the input line 15 and the output line 16. Therefore, this embodiment also includes a baffle 128, located inside the wiring cavity 12 and close to the partition through hole 141, so that the baffle 128 can block the partition through hole 141. To facilitate the fixing of the baffle 128, this embodiment provides corresponding fixing grooves 1210 on both sides of the wiring cavity 12. Specifically, the two sides of the baffle 128 are aligned with the fixing grooves 1210 and inserted until the bottom of the baffle 128 abuts against the plate surface of the wiring part 129.

[0114] For a better option, see Figure 17In this embodiment, since the number of terminals 121 is at least two, the baffle 128 is also provided with at least one second partition 124. The number of second partitions 124 is related to the number of terminals 121 (the number of second partitions = the number of terminals - 1). When the baffle 128 is installed in the fixing groove 1210, the second partition 124 divides the interior of the wiring cavity 12 into multiple cavities, so that adjacent terminals 121 are separated in sequence, and the terminals 121 in different cavities are connected to different input lines 15 and output lines 16 respectively, thereby improving the safety of the implementation.

[0115] For a better option, see Figure 17 and Figure 18 In this embodiment, the top of the wiring cavity 12 has an opening for inserting the terminal block 121 and plugging / unplugging the wire. A removable top cover 17 is provided at the opening, and the top cover 17 is interference-fitted with the inner wall of the wiring cavity 12 to protect the terminal block 121 inside the wiring cavity 12. Specifically, a plurality of slots 123 are provided on the inner wall of the wiring cavity 12, and a plurality of downward protrusions 171 are provided on the periphery of the top cover 17. The protrusions 171 can be inserted into the corresponding slots 123 and are interference-fitted with the slot walls of the slots 123. To facilitate the insertion of the protrusions 171, a groove is provided at the bottom of the protrusions 171 to facilitate deformation. Preferably, the top cover 17 has a through-hole for applying adhesive 172. When the top cover 17 is installed in the opening, adhesive is injected into the wiring cavity 12 through the adhesive hole 172 to achieve a waterproof seal. Due to the design of the glue injection hole 172, this embodiment allows for waterproof sealing by injecting glue into the upper cover 17 after it is fixed. If glue is applied before the upper cover 17 is placed on top, the glue may not be fully injected. To avoid affecting the glue injection, the top edge of the second partition 124 away from the baffle 128 is chamfered. Glue injection enables this embodiment to achieve an IP68 waterproof sealing rating.

[0116] For a better option, see Figure 19 and Figure 20To achieve a seal in the wiring cavity 12, a removable protective cover 183 can be provided at the opening. The protective cover 183 is press-fitted with the inner wall of the wiring cavity 12 to protect the wiring terminals 121 inside the wiring cavity 12. Similar to the top cover 17, the protective cover 183 also has several downward protrusions 171 on its periphery. The protrusions 171 can be inserted into corresponding slots 123 and are press-fitted with the slot walls of the slots 123. To facilitate the insertion of the protrusions 171, a groove is provided at the bottom of the protrusions 171 to facilitate deformation. The difference is that the top cover 17 requires potting to achieve a waterproof seal, while the protective cover 183 achieves a waterproof seal by providing a shielding member 181 at its bottom. When the protective cover 183 is placed at the opening, the shielding member 181 fills and seals the wiring cavity 12, thereby achieving a waterproof seal. In addition, in order to ensure the normal connection of the terminal block 121, a through groove is provided in the shield 181 that runs through the entire protective cover 183, so that when the protective cover 183 is placed at the opening, the terminal block 121 is exactly located in the through groove.

[0117] Compared to existing drivers on the market, which are determined at the factory whether or not to be potted and cannot be changed, this embodiment allows users to choose whether to add a top cover and pot it with glue, or to add only a protective cover without potting, based on their needs. This choice makes a difference between adding a top cover and a protective cover, but does not change the structure of other products, resulting in a more cost-effective solution.

[0118] For a better option, see Figure 18 In this embodiment, the bottom of the top cover 17 is also provided with at least one blocking groove 173. When the top cover 17 is installed in the opening, the second partition 124 is inserted into the corresponding blocking groove 173. The two side plates of the second partition 124 cooperate with the two side walls of the blocking groove 173 to form a wave-shaped maze structure. The maze structure separates the wiring terminal 121 and the wires on the terminal, thereby improving the safety of the implementation.

[0119] For a better option, see Figure 20 In this embodiment, the bottom of the protective cover 183 is also provided with at least one blocking groove 173, and the two side walls of the blocking groove 173 are the outer side surfaces of the adjacent shielding member 181. When the protective cover 183 is installed in the opening, the second partition is inserted into the corresponding blocking groove 173. The two side plates of the second partition, together with the two side walls of the blocking groove 173, form a wave-shaped maze structure. The maze structure separates the wiring terminal 121 and the wires on the terminal, thereby improving the safety of the implementation.

[0120] Next, communication unit 2 will be described: see Figure 6In one specific connection method, the communication unit 2 in this embodiment is hooked onto the side wall of the outer casing 1. Specifically, a sliding groove 18 extending along the height direction is provided on the side wall of the outer casing 1. The sliding groove 18 is L-shaped, and a corresponding slider 21 is provided on the side where the communication unit 2 connects to the outer casing 1. In addition, a snap-fit ​​hole 19 is also provided on the same side wall of the outer casing 1 where the sliding groove 18 is provided, and a corresponding first snap-fit ​​22 is provided on the side where the communication unit 2 connects to the outer casing 1. By inserting the slider 21 of the driver into the sliding groove 18 and sliding it until the first snap-fit ​​22 is engaged in the snap-fit ​​hole 19, the communication unit 2 and the outer casing 1 can be fixed.

[0121] More preferably, see Figure 7 and Figure 8 In this embodiment, a recess 23 is provided on the top or bottom surface of the communication unit 2, and a first buckle 22 is provided in the recess 23, with one end of the first buckle 22 extending to the top notch 125 of the recess, so as to facilitate the user to press and disassemble.

[0122] According to the above embodiments, it was found that the communication unit 2 is external to the housing 1, effectively isolating it from the high-temperature environment and potential electromagnetic radiation sources generated during the operation of the internal circuitry of the housing 1, thereby significantly reducing the temperature impact and electromagnetic interference on the communication unit 2. This design ensures the stability and reliability of the communication unit 2, reduces communication failures caused by environmental factors, and improves communication quality and operating efficiency. Furthermore, the communication unit 2 is fixed to the side wall of the housing 1 via a hook structure, eliminating the need for other external fixing or positioning components, facilitating the assembly and disassembly of the communication unit 2. Additionally, the electrical connection between the communication unit 2 and the housing 1 via a connecting wire provides superior waterproofing.

[0123] More preferably, see Figure 8 In this embodiment, the communication unit 2 is also provided with multiple through holes 24. The communication unit 2 can be installed on the outer casing 11 as needed, or directly fixed to the electrical cavity of the lamp by inserting screws into the through holes 24, to meet the needs of different electrical cavities. Furthermore, the through holes 24 in this embodiment are strip-shaped holes, accommodating more screw posts within the electrical cavities.

[0124] Preferably, in this embodiment, a wiring port 122 may be provided on the outer casing 1 or the communication unit 2, and corresponding wiring terminals 121 may be provided on the communication unit 2 or the outer casing 1 connected thereto. The outer casing 1 and the communication unit 2 are connected through the wiring port 122 and the wiring terminals 121. Furthermore, a limiting member 25 is provided on the outer casing 1 or the communication unit 2 to further secure the connected outer casing 1 and communication unit 2. Figure 13 For example, the wiring port 122 is located on the top surface of the housing 1, and the bottom surface of the communication unit 2 is provided with a corresponding wiring terminal 121.

[0125] See Figure 9 and Figure 10 In one specific implementation, limiting members 25 are respectively disposed on both sides of the communication unit 2, and a second buckle 251 is provided on the end of the limiting member 25 that is not connected to the communication unit 2. The outer shell 1 is provided with a corresponding second opening. After the wiring port 122 is inserted and fixed to the wiring terminal 121, the second buckle 251 is inserted into the outer shell 1 through the corresponding second opening and locked. In this embodiment, the limiting member 25 is integrally formed with the outer shell of the communication unit 2, but the limiting member 25 can also be independent of the communication unit 2 and installed on the communication unit 2 by means of adhesive bonding or other fixing methods.

[0126] See Figure 11 and Figure 12 In another specific implementation, the limiting member 25 is disposed on the outer shell 1 and faces upward. The end of the limiting member 25 that is not connected to the outer shell 1 is bent to form a first engaging part 252. A third buckle 253 is provided on the first engaging part 252. Correspondingly, a corresponding buckle groove 254 is provided on the communication unit 2. When the wiring port 122 is inserted and fixed to the wiring terminal 121, the first engaging part 252 is inserted into the buckle groove 254, so that the third buckle 253 is engaged with the buckle groove 254, thereby keeping the communication unit 2 and the outer shell 1 fixed.

[0127] like Figure 13 As shown, in one feasible embodiment, the limiting member 25 is fixedly connected to the outer shell 1 with screws.

[0128] like Figure 11 and Figure 12 As shown, in another feasible embodiment, the end of the limiting member 25 connected to the outer shell 1 extends downward and bends to form a second engaging portion 255. A fourth buckle 256 is provided on the second engaging portion 255. Similarly, a corresponding opening 257 is provided on the outer shell 1. The second engaging portion 255 is inserted into the opening 257, so that the fourth buckle 256 is engaged with the opening 257 to achieve fixation. This structure does not require screws or other parts; it only requires pressing to engage, making installation convenient. At the same time, to facilitate the insertion of the second engaging portion 255, a transition section 258 is provided between the second engaging portion 255 and the adjacent first engaging portion. The limiting member 25 is inclined downward from the second engaging portion 255 toward the first engaging portion 252 in the transition section 258. After installation and connection, the bottom of the two second engaging portions 255 of the limiting member 25 still leaves a gap with the outer shell 1, which facilitates the deformation of the second engaging portion 255 to complete the engaging action.

[0129] More preferably, in order to ensure a secure fastening, a leveling structure 26 is provided between the outer shell 1 and the communication unit 2, which is used to adjust the position of the communication unit 2 and the outer shell 1 so that the front and rear ends of the communication unit 2 can be at the same height after installation.

[0130] by Figure 13 For example, as a feasible embodiment, a wiring port 122 is provided on the top surface of the outer casing 1, and the wiring port 122 protrudes from the top surface of the outer casing 1. At this time, a first leveling structure 26 is adopted, which is a support member 261. The support member 261 is provided on both sides of the bottom of the communication unit 2, and can be integrally formed with the outer casing of the communication unit 2, and is away from the wiring terminal 121 on the communication unit 2. When the wiring port 122 is inserted and fixed with the wiring terminal 121, the support member 261 abuts against the outer casing 1, so that after the communication unit 2 is fixed, the front and rear ends are at the same height.

[0131] More preferably, with Figure 14 For example, as another feasible embodiment, a wiring port 122 is provided on the top surface of the outer casing 1, and the wiring port 122 does not protrude from the top surface of the outer casing 1. In this case, a second leveling structure 26 is adopted, which is a relief groove 262. The relief groove 262 is provided at the bottom of the communication unit 2. After the wiring port 122 is inserted and fixed with the wiring terminal 121, the limiting member 25 is located in the relief groove 262, thereby realizing that the front and rear ends of the communication unit 2 are at the same height.
