Description

Technical Field

[0001] This invention relates to the technical field of communication devices, and more particularly to a low-latency, anti-interference wireless communication device for the Internet of Things. Background Technology

[0002] With the large-scale deployment of scenarios such as industrial IoT, smart homes, and vehicle IoT, wireless communication terminals face two core rigid requirements: first, millisecond-level ultra-low latency transmission to meet the requirements of scenarios such as real-time control, synchronous data acquisition, and concurrent linkage of multiple devices; second, stable anti-interference capability in complex electromagnetic environments to avoid communication disconnection, latency spikes, and data packet loss caused by multi-device co-frequency interference, industrial electromagnetic radiation, and spatial signal attenuation.

[0003] In existing anti-interference wireless communication devices, most technical solutions employ openable and closable mechanical adjustment mechanisms to achieve physical anti-interference. However, these solutions have many inherent technical limitations, making them completely unsuitable for low-latency IoT scenarios, and their anti-interference effect is limited. Specific shortcomings are as follows: 1. The mechanism design is completely disconnected from low-latency communication: The existing opening and closing mechanism is only a pure mechanical adjustment structure. The adjustment logic takes the maximum signal strength as the only goal and has no low-latency priority constraint. The adjustment action is slow and the stroke is long. During the adjustment process, the signal synchronization will be interrupted directly, causing a sharp increase in communication latency. In some cases, in order to resist interference, the latency will exceed the standard and the equipment will go out of control. It cannot meet the core requirements of zero interruption, fast response and no packet loss of the Internet of Things. 2. Lack of anti-interference prediction mechanism and passive and delayed adjustment: Existing opening and closing mechanisms are all delayed responses of interference occurrence - signal deterioration - trigger adjustment. The adjustment has a significant delay and cannot predict interference in advance or adjust the antenna attitude in advance. In IoT scenarios with rapid interference changes and multiple devices communicating concurrently, the adjustment speed cannot keep up with the speed of interference changes. The anti-interference effect is continuously delayed and cannot stably guarantee low-latency transmission. 3. Unreasonable transmission and drive structure: Some solutions use multiple independent drive components, which are complex and not synchronized, which can easily lead to signal synchronization deviation and time delay superposition. At the same time, the drive components have slow response speed and low action accuracy. The antenna opening and closing action is completely out of sync with the air interface transmission and data frame transmission of the communication module. The delay of mechanical action will be directly superimposed on the total communication delay, and there is a significant time delay bottleneck at the hardware level. 4. Limited antenna reception range and insufficient anti-interference capability: The existing solution can only achieve opening and closing adjustment in one direction. The antenna reception angle is fixed and the coverage is narrow. It can only capture signals in one direction. When interference comes from other directions, it is impossible to avoid interference by adjusting the antenna attitude. It can only passively endure signal attenuation. The comprehensiveness and flexibility of anti-interference are extremely poor. 5. Lack of hardware and software co-design, resulting in poor protection and adaptability: Existing devices do not deeply integrate the opening and closing mechanism with the low-latency communication module, and lack clock co-source phase-locked loop design, resulting in signal standing wave loss and synchronization deviation, which further increases transmission latency. At the same time, some devices lack industrial-grade protection design, cannot adapt to the wide temperature range, dustproof and waterproof requirements of complex industrial environments, and lack targeted heat dissipation structure, resulting in insufficient long-term operational stability.

[0004] Existing technologies cannot simultaneously achieve low-latency transmission and adaptive anti-interference, making it difficult to meet the comprehensive requirements of the Industrial Internet of Things (IIoT) for stability, high speed, and anti-interference. Therefore, there is an urgent need for an IoT low-latency anti-interference wireless communication device with a reasonable structure, precise adjustment, controllable latency, and reliable protection. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, embodiments of the present invention provide a low-latency, anti-interference wireless communication device for the Internet of Things, which can solve the problems of existing communication devices such as slow adjustment, uncontrollable latency, incomplete antenna coverage, complex driving, hardware and software asynchrony, and poor environmental adaptability.

[0006] According to an embodiment of the present invention, a low-latency, interference-resistant wireless communication device for the Internet of Things includes: The main body of the box is equipped with a dedicated low-latency communication module for the Internet of Things, a synchronization control unit, and a front-end interference prediction unit on its inner walls. Adaptive opening and closing anti-interference mechanism: includes independent opening and closing antenna units respectively arranged on the four sides and top of the main body of the box, totaling five sides, and a single unified drive assembly fixedly connected to the inner wall of the main body of the box. Each independent opening and closing antenna unit includes an antenna opening and closing seat threadedly connected to the corresponding side of the main body of the box and a low-latency high-synchronization receiving antenna uniformly hinged and fixed to the end of the antenna opening and closing seat. The independent opening and closing antenna units on the five sides are all connected to the single unified drive assembly for transmission. The single unified drive assembly synchronously or independently drives the opening and closing movement of each independent opening and closing antenna unit. The low-latency high-synchronization receiving antennas in the independent opening and closing antenna units on the five sides can be merged and converged, protruding from the surface of the main body of the box and forming a column shape. After being separated, they can be spread outward to form an umbrella shape. The pre-interference prediction unit and the single unified drive component are both electrically connected to the synchronization control unit, which is electrically connected to the IoT low-latency dedicated communication module.

[0007] According to an embodiment of the present invention, the low-latency anti-interference wireless communication device for the Internet of Things includes an antenna opening and closing seat comprising a threaded guide seat, the threaded guide seat being threadedly connected to the inner wall of a threaded hole on the surface of the main body of the housing, the end of the threaded guide seat being uniformly provided with an installation groove, the bottom of the low-latency high-synchronization receiving antenna being hinged and fixedly fixed to the inner wall of the installation groove, and a reset torsion spring being fixedly connected between the antenna and the inner wall of the installation groove, a drive shaft being vertically slidably connected to the inner wall of the threaded guide seat, and a limit guide groove and a limit ball rod being respectively provided on the surface of the drive shaft and at positions corresponding to the surface of the low-latency high-synchronization receiving antenna, one end of the limit ball rod being located in the limit guide groove and slidably connected to the inner wall of the limit guide groove; The depth of the limiting guide groove gradually decreases from one end to the other. One end of the drive shaft penetrates into the interior of the box body and is connected to a single unified drive component.

[0008] According to an embodiment of the present invention, the Internet of Things low-latency anti-interference wireless communication device includes a single unified driving component that is connected to five independently opening and closing antenna units via a precision transmission mechanism. The precision transmission mechanism includes a central drive gear, branch drive gears, a micro electromagnetic clutch module, and threaded screws. The central drive gear is rotatably connected to the inner wall of the main body of the box and is connected to the output end of a single unified drive component. The branch drive gears are rotatably connected to the inner top wall and inner side wall of the main body of the box. One set of branch drive gears rotatably connected to the inner top wall of the main body of the box is fixedly connected to the central shaft of the central drive gear. The other four sets of branch drive gears rotatably connected to the inner side wall of the main body of the box are meshed with the central drive gear. There are five sets of threaded screws. The five sets of threaded screws are rotatably connected to the inner top wall and inner side wall of the main body of the box and are connected to the branch drive gears through the micro electromagnetic clutch module. One end of each of the five sets of threaded screws is provided with a key. The key is slidably connected in the keyway of the micro electromagnetic clutch module and is keyed. The end of the drive shaft that penetrates into the interior of the main body of the box is threaded to the outer surface of the threaded screw. The precision transmission mechanism has two driving modes: one-key synchronous opening and closing and independent control of single-face opening and closing, which can be flexibly switched by the synchronous control unit according to the interference situation and low latency requirements. During synchronous opening and closing, the synchronous control unit controls all micro electromagnetic clutch modules to be turned on simultaneously, and the power of the central drive gear is synchronously transmitted to the five antenna opening and closing seats through five branch transmission gears, so that the low-delay high-synchronization receiving antennas on the five antenna opening and closing seats separate and unfold outward to form an umbrella shape. When opening and closing independently, the synchronization control unit only connects the miniature electromagnetic clutch module on the corresponding surface. The power of the central drive gear is only transmitted to the branch transmission gear and the antenna opening and closing seat on that surface, so that the low-delay high-synchronization receiving antenna on the antenna opening and closing seat on the corresponding surface separates and unfolds outward to form an umbrella shape, while the low-delay high-synchronization receiving antenna on the antenna opening and closing seat on the other surfaces remains in a columnar folded state. The single unified drive component is a miniature high-speed closed-loop stepper motor with a response time of ≤10ms. Its output shaft is coaxially fixed to the central drive gear, and the four sets of branch drive gears are evenly arranged in a cross-symmetric manner around the central drive gear, with the included angle between two adjacent branch drive gears being 90°.

[0009] According to the IoT low-latency anti-interference wireless communication device provided in the embodiment of the present invention, the adjustment stroke and action speed of the five low-latency high-synchronization receiving antennas are all constrained by the phase-locked loop of the synchronization control unit. The adjustment action is strictly aligned with the air interface frame interval and data transmission gap of the IoT low-latency dedicated communication module. All opening and closing adjustment actions are completed within the communication window period. The pre-interference prediction unit is bidirectionally electrically connected to the IoT low-latency dedicated communication module and the synchronization control unit. It can scan the noise floor changes, co-channel interference trends, adjacent channel interference intensity and interference source direction of the current communication channel in real time. Before the interference amplitude reaches the communication threshold, the signal has not deteriorated, and the latency has not soared, it outputs a prediction adjustment command to the synchronization control unit in advance to control the single unified driving component to drive the independent opening and closing antenna unit in the corresponding direction to adjust its attitude.

[0010] According to the IoT low-latency anti-interference wireless communication device provided in the embodiment of the present invention, the synchronization control unit has a built-in low-latency priority opening and closing control algorithm. The algorithm takes communication latency, data packet loss rate and signal synchronization stability as the first priority constraint conditions and signal strength as the second optimization condition. During the adjustment process, the maximum adjustment stroke and minimum adjustment step size of each independent opening and closing antenna unit are strictly limited, and large-scale full-stroke adjustment that would cause signal synchronization interruption or excessive time delay is prohibited.

[0011] According to the embodiments of the present invention, the IoT low-latency anti-interference wireless communication device adopts the IoT dedicated low-latency wireless protocol, and the communication air interface latency is ≤50ms. The synchronization clock of the IoT dedicated low-latency communication module is phase-locked with the synchronization control unit and the clock of the single unified drive component.

[0012] According to the embodiments of the present invention, the low-latency anti-interference wireless communication device for the Internet of Things has five antenna opening and closing bases made of low-loss non-metallic dielectric material, and the low-latency high-synchronization receiving antenna adopts an equal-length synchronous feeder. The opening and closing action maintains antenna impedance matching and signal synchronization deviation ≤5ns throughout the entire process.

[0013] According to the embodiment of the present invention, the Internet of Things low-latency anti-interference wireless communication device has a synchronization control unit based on a low-latency priority opening and closing control algorithm. It sets a graded adjustment mode according to the interference intensity and direction, combined with the structural characteristics of the five-sided antenna, including a weak interference micro-adjustment mode, a medium-strong interference graded step adjustment mode, and an extreme interference collaborative adjustment mode.

[0014] According to the IoT low-latency anti-interference wireless communication device provided in the embodiments of the present invention, in weak interference scenarios, the synchronization control unit controls the antenna in the direction of interference to make micro-adjustments with very small steps; in medium-strong interference scenarios, the synchronization control unit controls the antenna in the corresponding direction to perform graded step adjustments during the communication gap period; in extreme interference scenarios, the synchronization control unit first locks the communication synchronization link, and then controls the single unified driving component to drive the antennas of multiple surfaces to adjust in a coordinated manner.

[0015] According to the embodiments of the present invention, the IoT low-latency anti-interference wireless communication device adopts an industrial-grade protection design for its housing body, which has an IP65 protection rating and is suitable for a wide temperature operating environment of -40℃ to +85℃. The main body of the box has a built-in fan heat dissipation component, and the IoT low-latency dedicated communication module, synchronization control unit, front-end interference prediction unit and single unified drive component are all fixedly connected to the top of the support shell of the fan heat dissipation component. The fan cooling assembly has a built-in sensor sensing component, which includes a temperature sensor, a humidity sensor, a pressure sensor, and a flow rate sensor. The cooling fan and sensor sensing component in the fan heat dissipation assembly are connected to the synchronous control unit via wires to realize sensor data transmission and receive control commands for the cooling fan.

[0016] The low-latency, anti-interference wireless communication device for the Internet of Things provided by the embodiments of the present invention has at least the following beneficial effects: 1. Completely resolve the core contradiction between low latency and anti-interference: Through the pre-interference prediction mechanism, interference is avoided in advance to prevent latency spikes caused by delayed adjustment. The clock homogeneous phase-locked loop design and window adjustment logic of the synchronous control unit ensure that antenna adjustment does not interrupt communication or add latency. Combined with the low latency priority algorithm, the adjustment action is strictly constrained to achieve anti-interference without sacrificing latency and low latency without reducing stability. 2. Significantly enhanced all-round anti-interference capability: The innovative design of five independently opening and closing antennas in the box form an umbrella-shaped structure when unfolded, covering the entire space reception angle. It can accurately avoid interference from different directions. The five antennas work together to achieve multi-directional signal superposition, reduce signal attenuation, and the comprehensiveness and flexibility of anti-interference far exceed the existing single-direction opening and closing scheme. 3. More rational transmission and drive structure: The single unified drive component, combined with the precision transmission mechanism, simplifies the overall structure, reduces the size and cost of the equipment, and avoids the synchronization deviation caused by multiple asynchronous drives. The micro high-speed closed-loop stepper motor meshes with high-precision gears, combined with electromagnetic clutch dual-mode control, which improves the adjustment accuracy and response speed, and realizes the antenna synchronous or independent flexible adjustment. 4. Deep hardware and software collaboration significantly improves transmission stability: The dedicated low-latency communication module for IoT is clocked in the same phase-locked loop as the synchronization control unit and drive components. The antenna uses low-loss materials and equal-length synchronous feed lines. The opening and closing action maintains impedance matching and synchronization deviation ≤5ns throughout the process, with no additional synchronization loss and standing wave interference, further ensuring low-latency transmission. 5. Comprehensive upgrade in scene adaptability: Industrial-grade IP65 protection, wide temperature design from -40℃ to +85℃, combined with fan heat dissipation components and multi-sensor monitoring, can adapt to complex IoT scenarios such as industrial control, vehicle linkage, and field monitoring. The graded adjustment mode adapts to different interference intensities, flexibly responding to the needs of scenarios such as dynamic interference and multiple devices in parallel, and its applicable scope far exceeds that of existing general-purpose devices. 6. Compact structure and stable and reliable operation: The five antennas are combined to form a columnar structure, which is compact. All electrical modules are built into the box to avoid external electromagnetic interference. At the same time, the fan heat dissipation component ensures stable operation of the equipment in real time and reduces failures caused by overheating and environmental factors. Its long-term operational stability is far superior to existing technologies. 7. Precise adjustment and flexible operation: Through the cooperation of the limit guide groove and the limit ball rod, combined with the feedback control of the closed-loop stepper servo, the antenna adjustment accuracy is improved. The synchronous / independent dual adjustment mode can be flexibly switched according to the interference situation, which not only meets the requirements of all-round anti-interference, but also avoids unnecessary adjustment actions, further reducing time delay and energy consumption. 8. The present invention has a simple overall structure, clear control logic, and stable and reliable operation, and can be widely applied to various low-latency and high-reliability communication scenarios such as industrial control, smart home, vehicle IoT, and field monitoring.

[0024] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of these terms in this invention in conjunction with the specific content of the technical solution.

[0025] refer to Figures 1 to 10 This invention provides a low-latency, anti-interference wireless communication device for the Internet of Things, comprising: Box body 1: Its inner wall is respectively provided with IoT low latency dedicated communication module 12, synchronization control unit 13 and front interference prediction unit 14; The adaptive opening and closing anti-interference mechanism 2 includes five independent opening and closing antenna units 21 respectively set on the four sides and the top of the main body 1, and a single unified drive assembly 22 fixedly connected to the inner wall of the main body 1. Each independent opening and closing antenna unit 21 includes an antenna opening and closing seat 211 threadedly connected to the corresponding side of the main body 1 and a low-delay high-synchronization receiving antenna 212 uniformly hinged and fixed to the end of the antenna opening and closing seat 211. The five independent opening and closing antenna units 21 are all connected to the single unified drive assembly 22 for transmission. The single unified drive assembly 22 drives the opening and closing movement of each independent opening and closing antenna unit 21 synchronously or independently. The low-delay high-synchronization receiving antennas 212 in the five independent opening and closing antenna units 21 converge and protrude from the surface of the main body 1 to form a column shape after merging, and unfold outward to form an umbrella shape after separating. The pre-interference prediction unit 14 and the single unified drive component 22 are both electrically connected to the synchronization control unit 13, and the synchronization control unit 13 is electrically connected to the IoT low-latency dedicated communication module 12.

[0026] It should be noted that the bottom and surface of the box body 1 described in this embodiment are respectively provided with a negative pressure suction seat 100 and a dustproof heat dissipation grille 200.

[0027] It should be understood that this device prioritizes low latency, anticipates future events, coordinates synchronously, and provides omnidirectional interference resistance. All components are housed within the main body 1, and low-latency transmission and omnidirectional interference resistance are achieved through the coordinated operation of these structures. Its specific working principle is as follows: 1. Overall architecture coordination: The main body 1 of the box serves as the core load-bearing component. Its inner wall integrates a dedicated low-latency communication module 12 for the Internet of Things, a synchronization control unit 13, and a front-end interference prediction unit 14, and has a built-in fan heat dissipation component 11. An adaptive opening and closing anti-interference mechanism 2 is set externally, which includes an independent opening and closing antenna unit 21. All components are connected by lines to form a complete closed loop of perception-control-execution-feedback.

[0028] 2. Interference prediction and control: The pre-interference prediction unit 14 is bidirectionally electrically connected to the synchronization control unit 13 and the IoT low-latency dedicated communication module 12. It scans the noise floor changes, co-channel interference, adjacent channel interference and interference source direction of the current communication channel in real time. Before the interference amplitude reaches the communication threshold, the signal deteriorates and the latency spikes, it outputs the prediction and adjustment command to the synchronization control unit 13 in advance to achieve interference avoidance in advance and avoid the increase in latency caused by lagging adjustment.

[0029] It should be noted that the interference threshold described in this embodiment is a conventional communication threshold in the art, which is preset by the system at the factory or adaptively set by the user according to the actual application scenario. It is a conventional technical means in the art and can be implemented by those skilled in the art without creative effort.

[0030] 3. Synchronization Control and Timing Constraints: The synchronization control unit 13 has a built-in low-latency priority opening and closing control algorithm, which prioritizes communication latency, data packet loss rate, and signal synchronization stability, and uses signal strength as the second optimization condition. At the same time, it achieves clock co-location phase-locking with the IoT low-latency dedicated communication module 12 and the single unified drive component 22, ensuring that all adjustment actions are strictly aligned with the air interface frame interval and data transmission gap of the communication module. All antenna adjustment actions are completed within the communication window period without interrupting signal transmission or adding extra latency.

[0031] 4. Precision Transmission and Attitude Adjustment: A single unified drive component 22 (a miniature high-speed closed-loop stepper servo with a response time ≤10ms) drives the central drive gear 231 to rotate. The central drive gear 231 meshes with five sets of branch transmission gears 232 (corresponding to the five antenna faces). Power switching is achieved through a miniature electromagnetic clutch module 233. Power is transmitted to the drive shaft 2114 via a threaded screw 234. When the threaded screw 234 rotates, it drives the drive shaft 2114 to move linearly along the axial direction through the threaded engagement. The displacement of the drive shaft 2114 corresponds one-to-one with the rotation angle of the threaded screw 234. The adjustment precision is controllable, with no idle stroke and no slippage, ensuring that the antenna opening and closing angle is highly consistent with the drive command height. The drive shaft 2114 is connected to the low-latency high-synchronization receiving antenna 212 through a limiting guide groove 2115, driving the low-latency high-synchronization receiving antenna 212 to open and close—it converges into a column shape when closed and unfolds into an umbrella shape when unfolded, realizing full-space signal reception.

[0032] 5. Hierarchical Adjustment and Closed-Loop Feedback: Based on the interference intensity identified by the pre-interference prediction unit 14, the synchronization control unit 13 adopts a hierarchical adjustment mode: for weak interference, it controls the corresponding antenna to make fine adjustments; for medium to strong interference, it performs step adjustments during the communication window; for extreme interference, it prioritizes locking the communication synchronization link and then drives the multi-antenna to adjust in a coordinated manner; after adjustment, the optimized signal is fed back to the IoT low-latency dedicated communication module 12, forming a complete closed loop of signal transmission-interference prediction-adjustment optimization-signal stabilization. All three hierarchical adjustment modes are executed during the communication window, without occupying data transmission time or disrupting frame structure synchronization, ensuring that communication is not interrupted, latency does not spike, and packet loss does not increase during the adjustment process.

[0033] 6. Auxiliary support: The fan heat dissipation component 11 is equipped with temperature and humidity sensors, which collect environmental data in real time and transmit it to the synchronous control unit 13. The heat dissipation intensity is automatically adjusted according to the data to ensure that each module operates stably in a wide temperature range of -40℃ to +85℃. The main body of the box 1 adopts an IP65 protection rating and is equipped with a dustproof heat dissipation grille 200 to further improve the environmental adaptability of the device and avoid external interference from affecting the operation of internal components.

[0034] According to the embodiments of the present invention, the low-latency anti-interference wireless communication device for the Internet of Things includes an antenna opening and closing base 211 comprising a threaded guide 2111, which is threadedly connected to the inner wall of the threaded hole 10 on the surface of the main body 1 of the housing. The threaded guide 2111 has a uniformly provided mounting groove 2112 at its end. The bottom of the low-latency high-synchronization receiving antenna 212 is hinged and fixed to the inner wall of the mounting groove 2112, and a reset torsion spring 2113 is fixedly connected between the antenna and the inner wall of the mounting groove 2112. A drive shaft 2114 is vertically slidably connected to the inner wall of the threaded guide 2111. A limiting guide groove 2115 and a limiting ball rod 2116 are respectively provided at positions corresponding to the surface of the low-latency high-synchronization receiving antenna 212 on the surface of the drive shaft 2114. One end of the limiting ball rod 2116 is located in the limiting guide groove 2115 and is slidably connected to the inner wall of the limiting guide groove 2115. The depth of the limiting guide groove 2115 gradually decreases from one end to the other. One end of the drive shaft 2114 extends into the interior of the main body 1 of the box and is connected to the single unified drive component 22.

[0035] It should be understood that the antenna opening and closing seat 211 is securely connected to the threaded hole 10 of the main body 1 of the housing through the threaded guide seat 2111. The mounting groove 2112 hinges the low-latency high-synchronization receiving antenna 212 and provides the rebound force by the reset torsion spring 2113. The drive shaft 2114 moves up and down under the drive of a single unified drive component 22. The depth of the limiting guide groove 2115 gradually pushes the limiting ball rod 2116. When the drive shaft 2114 moves upward, the depth of the limiting guide groove 2115 gradually pushes the limiting ball rod 2116 to open outward, so that the low-latency high-synchronization receiving antenna 212 overcomes the torque of the reset torsion spring 2113 and unfolds outward. When the drive shaft 2114 moves downward, the reset torsion spring 2113 drives the antenna to automatically retract and reset. The opening and closing action is smooth, without jamming or impact, and converts linear motion into the opening and closing action of the antenna, realizing stable, smooth and precise attitude adjustment, ensuring reliable antenna retraction and unfolding, and improving anti-interference and signal reception effects.

[0036] According to the embodiment of the present invention, the Internet of Things low latency anti-interference wireless communication device has a single unified driving component 22 connected to five independently opening and closing antenna units 21 via a precision transmission mechanism 23. The precision transmission mechanism 23 includes a central drive gear 231, branch transmission gears 232, a miniature electromagnetic clutch module 233, and a lead screw 234. The central drive gear 231 is rotatably connected to the inner wall of the main body 1 and is connected to the output end of the single unified drive component 22. The branch transmission gears 232 are rotatably connected to the inner top wall and inner side wall of the main body 1, respectively. One group of branch transmission gears 232 rotatably connected to the inner top wall of the main body 1 is fixedly connected to the central shaft of the central drive gear 231. The remaining four groups of branch transmission gears 232 rotatably connected to the inner side wall of the main body 1 are fixedly connected to the central shaft of the central drive gear 231. All gears 232 are meshed with the central drive gear 231. Five sets of threaded screws 234 are provided. The five sets of threaded screws 234 are rotatably connected to the inner top wall and inner side wall of the main body 1 of the box, and are connected to the branch transmission gear 232 through the micro electromagnetic clutch module 233. One end surface of each of the five sets of threaded screws 234 is provided with a slotted key 235. The slotted key 235 is slidably connected in the keyway of the micro electromagnetic clutch module 233 and keyed. One end of the drive shaft 2114 that penetrates into the interior of the main body 1 is threaded to the outer surface of the threaded screw 234. The precision transmission mechanism 23 has two driving modes: one-button synchronous opening and closing and independent control of single-face opening and closing. The synchronous control unit 13 can flexibly switch between them according to the interference situation and low latency requirements. During synchronous opening and closing, the synchronous control unit 13 controls all micro electromagnetic clutch modules 233 to be turned on simultaneously, and the power of the central drive gear 231 is transmitted synchronously to the five antenna opening and closing seats 211 through the five branch transmission gears 232, so that the low-delay high-synchronization receiving antennas 212 on the five antenna opening and closing seats 211 separate and unfold outward to form an umbrella shape. When opening and closing independently, the synchronous control unit 13 only connects the miniature electromagnetic clutch module 233 on the corresponding surface. The power of the central drive gear 231 is only transmitted to the branch transmission gear 232 and the antenna opening and closing seat 211 on that surface, so that the low-delay high-synchronization receiving antenna 212 on the antenna opening and closing seat 211 on the corresponding surface opens outward to form an umbrella shape, while the low-delay high-synchronization receiving antenna 212 on the antenna opening and closing seat 211 on the other surfaces remains in a columnar folded state. The single unified drive component 22 is a miniature high-speed closed-loop stepper servo with a response time of ≤10ms. Its output shaft is coaxially fixed with the central drive gear 231, and four branch transmission gears 232 are evenly arranged in a cross-symmetric manner around the central drive gear 231. The included angle between two adjacent branch transmission gears 232 is 90°.

[0037] It should be noted that the miniature electromagnetic clutch module 233 described in this embodiment engages to transmit power when energized and disengages to interrupt power when de-energized, thereby achieving independent / synchronous drive switching of a single antenna or all antennas, which is a conventional clutch control method in the field.

[0038] It should be understood that the single unified drive component 22 provides power to the five independently opening and closing antenna units 21 through the precision transmission mechanism 23. The central active gear 231 drives the cross-shaped symmetrically arranged branch transmission gears 232 to rotate, which in turn drives the threaded screw 234 to rotate through the micro electromagnetic clutch module 233 and the key section 235, thereby driving the drive shaft 2114 to move linearly. The synchronous control unit 13 controls the on and off of the micro electromagnetic clutch module 233 to realize the synchronous deployment of the five antennas or the independent adjustment of one antenna. The structure is simple and the response is fast. It can realize umbrella-shaped omnidirectional reception and targeted anti-interference. It is stable and reliable throughout the process and has lower latency.

[0039] According to the embodiment of the present invention, the adjustment stroke and action speed of the five low-latency high-synchronization receiving antennas 212 are all constrained by the phase-locked loop of the synchronization control unit 13. The adjustment action is strictly aligned with the air interface frame interval and data transmission gap of the IoT low-latency dedicated communication module 12. All opening and closing adjustment actions are completed within the communication window period. The pre-interference prediction unit 14 is bidirectionally electrically connected to the IoT low-latency dedicated communication module 12 and the synchronization control unit 13. It can scan the noise floor changes, co-channel interference trends, adjacent channel interference intensity and interference source direction of the current communication channel in real time. Before the interference amplitude reaches the communication threshold, the signal has not deteriorated, and the latency has not soared, it outputs the prediction adjustment command to the synchronization control unit 13 in advance to control the single unified drive component 22 to drive the independent opening and closing antenna unit 21 in the corresponding direction to adjust its attitude.

[0040] It should be understood that the adjustment range and speed of the five low-latency high-synchronization receiving antennas 212 are constrained by the phase-locked loop control unit 13. The operation strictly matches the air interface frame interval and data transmission gap of the IoT low-latency dedicated communication module 12. All adjustments are completed within the communication window period without interrupting transmission or increasing latency. The pre-interference prediction unit 14 monitors channel interference in real time and outputs adjustment commands in advance, enabling the device to complete attitude adjustment before the signal deteriorates, thus achieving pre-interference anti-interference and stable communication with low latency and no interruption.

[0041] According to the embodiment of the present invention, the Internet of Things low latency anti-interference wireless communication device has a built-in low latency priority opening and closing control algorithm in the synchronization control unit 13. The algorithm takes communication latency, data packet loss rate and signal synchronization stability as the first priority constraint conditions and signal strength as the second optimization condition. During the adjustment process, the maximum adjustment stroke and minimum adjustment step size of each independently opening and closing antenna element 21 are strictly limited, and large-scale full-stroke adjustment that would cause signal synchronization interruption and excessive time delay is prohibited.

[0042] It should be understood that the synchronization control unit 13 has a built-in low-latency priority opening and closing control algorithm, which prioritizes communication latency, packet loss rate and signal synchronization, and uses signal strength as the second optimization condition. During adjustment, the stroke and step size of the independent opening and closing antenna unit 21 are strictly limited to avoid large movements that could cause synchronization interruption and latency exceeding the standard, thus ensuring stable and low latency throughout the communication process.

[0043] The specific implementation logic of the low-latency priority opening and closing control algorithm is as follows: First, the latency data, packet loss rate, and signal synchronization status of the IoT low-latency dedicated communication module 12 are acquired in real time. These parameters are used as core constraints to ensure that communication is not interrupted and latency does not exceed the standard. Then, based on the interference intensity and direction input by the pre-interference prediction unit 14, the required adjustment angle and adjustment step size of the antenna are calculated. The adjustment range is strictly limited to not exceeding the safety threshold. All adjustment commands are issued and executed within the communication window period to ensure that the adjustment process does not affect normal communication. Finally, the optimal anti-interference effect is achieved under the premise of meeting the low-latency constraint.

[0044] According to the embodiments of the present invention, the IoT low-latency anti-interference wireless communication device adopts the IoT dedicated low-latency wireless protocol in the IoT dedicated low-latency communication module 12, with a communication air interface latency of ≤50ms. The synchronization clock of the IoT low-latency dedicated communication module 12 is phase-locked with the clock of the synchronization control unit 13 and the single unified drive component 22.

[0045] It should be noted that the clock-source phase-locked loop described in this embodiment uses a unified clock source to provide a reference signal, so that the communication module, control unit and drive components maintain the same timing reference. This is a conventional synchronization method in the field of Internet of Things communication, and can be implemented by those skilled in the art.

[0046] It should be understood that the IoT low-latency dedicated communication module 12 adopts a dedicated low-latency wireless protocol with an air interface latency of ≤50ms. It also maintains clock synchronization with the synchronization control unit 13 and the single unified drive component 22, ensuring a high degree of consistency in the timing of communication, control, and drive, thereby further improving system synchronization and transmission stability.

[0047] According to the embodiments of the present invention, the low-latency anti-interference wireless communication device for the Internet of Things has five antenna opening and closing bases 211 made of low-loss non-metallic dielectric material, and the low-latency high-synchronization receiving antenna 212 adopts an equal-length synchronous feeder. The opening and closing action maintains antenna impedance matching and signal synchronization deviation ≤5ns throughout the entire process.

[0048] It should be understood that the five-sided antenna opening and closing base 211 uses a low-loss non-metallic dielectric material, and the low-latency high-synchronization receiving antenna 212 uses an equal-length synchronous feeder to maintain antenna impedance matching throughout the opening and closing process. The signal synchronization deviation is ≤5ns, which effectively reduces signal loss and ensures stable communication and ultra-low latency transmission.

[0049] According to the embodiments of the present invention, the Internet of Things low-latency anti-interference wireless communication device has a synchronization control unit 13 based on a low-latency priority opening and closing control algorithm. It sets a graded adjustment mode according to the interference intensity and direction, combined with the structural characteristics of the five-sided antenna, including a weak interference micro-adjustment mode, a medium-strong interference graded step adjustment mode, and an extreme interference collaborative adjustment mode.

[0050] It should be noted that the classification of weak, medium-strong, and extreme interference levels described in this embodiment adopts the common signal strength and interference level judgment standard in the field. The system can automatically identify and classify them without the need for additional creative algorithms.

[0051] It should be understood that the synchronization control unit 13 is based on a low-latency priority opening and closing control algorithm. According to the interference intensity and direction, it adopts a graded adjustment based on the five-sided antenna structure. It is divided into three modes: weak interference micro-adjustment, medium-strong interference graded step adjustment, and extreme interference coordinated adjustment, to adapt to different interference scenarios and achieve precise and efficient anti-interference while ensuring low latency.

[0052] According to the IoT low-latency anti-interference wireless communication device provided in the embodiment of the present invention, in the weak interference scenario, the synchronization control unit 13 controls the antenna in the interference direction to make a micro-adjustment with a very small step size. In the medium-strong interference scenario, the synchronization control unit 13 controls the antenna in the corresponding direction to perform hierarchical step adjustment during the communication window period. In the extreme interference scenario, the synchronization control unit 13 first locks the communication synchronization link, and then controls the single unified driving component 22 to drive the antennas of multiple surfaces to adjust in a coordinated manner.

[0053] It should be understood that, under weak interference, the synchronization control unit 13 controls the antenna in the corresponding direction to make small adjustments; under medium to strong interference, the target antenna is adjusted in stages during the communication gap; under extreme interference, the communication synchronization link is locked first, and then the multi-antenna is coordinated and adjusted through a single unified drive component 22, taking into account both low latency and anti-interference stability throughout the process.

[0054] According to the embodiments of the present invention, the IoT low-latency anti-interference wireless communication device has an industrial-grade protective design for the main body 1, which has an IP65 protection rating and is suitable for a wide temperature working environment of -40℃ to +85℃. The main body 1 of the box has a built-in fan heat dissipation component 11. The IoT low latency dedicated communication module 12, the synchronization control unit 13, the front interference prediction unit 14 and the single unified drive component 22 are all fixedly connected to the top of the supporting shell of the fan heat dissipation component 11. The fan cooling assembly 11 has a built-in sensor sensing component, which includes a temperature sensor, a humidity sensor, a pressure sensor, and a flow rate sensor. The cooling fan and sensor sensing component in the fan heat dissipation assembly 11 are connected to the synchronous control unit 13 via wires to realize sensor data transmission and receive control commands for the cooling fan.

[0055] It should be understood that the main body 1 of the box adopts an industrial-grade IP65 protection design, which can work stably in a wide temperature range of -40℃ to +85℃. It has a built-in fan heat dissipation component 11, and the core electronic control module is installed on its supporting shell. The fan heat dissipation component 11 integrates multiple environmental sensors and is connected to the synchronous control unit 13, which can monitor environmental data in real time and automatically adjust heat dissipation to ensure long-term reliable operation of the device.
