Description

Technical Field

[0001] This invention belongs to the field of set-top box signal enhancement technology, specifically a set-top box signal reflector for easy remote control positioning and a method for optimizing remote control signals. Background Technology

[0002] A digital video converter box (STB) is a device that connects a television set to an external signal source. It converts compressed digital signals into television content and displays it on the television set. The signal can come from cable TV, satellite dish, broadband network, or terrestrial broadcast. When watching TV, users need to use the remote control to send control signals to the set-top box to complete functions such as picture and volume adjustment. Due to different room layouts, the set-top box is usually placed in different locations for different users, which may result in some blind spots in the signal receiving area of ​​the set-top box's signal receiving structure. This situation will ultimately affect the remote control's positioning and control, and thus affect the user's viewing experience. Summary of the Invention

[0003] The purpose of this invention is to provide a set-top box signal reflector and a remote control signal optimization method that facilitates remote control positioning, in order to solve the problems mentioned in the background art, such as the difficulty in eliminating blind spots in set-top box signal reception, cumbersome remote control positioning operations, insufficient equipment adaptability, and limited heat dissipation efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A set-top box signal reflector for easy remote control positioning, a set-top box body, a base at the bottom of the set-top box body, a mounting bracket fixedly connected to the front of the inner wall of the base, a reflection adjustment component on the front of the base, an upper shell fixedly connected to the top of the base, the upper shell being located at the top of the set-top box body, and a front shell communicating with the front of the set-top box body. The reflection adjustment assembly includes a horizontal reflector, a vertical reflector, and an induction antenna. The back of the horizontal reflector is rotatably connected to a drive unit for adjusting its attitude, and the vertical reflector is rotatably connected to the front shell. A control module is fixedly connected to the bottom of the inner wall of the set-top box body. The control module is electrically connected to the drive unit and the induction antenna respectively. The induction antenna is used to receive infrared signals from the remote control and feed them back to the control module. The control module adjusts the action of the driving components according to the signal strength to adjust the reflection posture of the horizontal and vertical reflectors.

[0005] According to the above technical solution, the horizontal reflector includes a horizontal plate body, the driving component is a stepper rod, the number of stepper rods is four, and they are evenly distributed on the back of the horizontal plate body. The end of the stepper rod is fixedly connected to the outer surface of the mounting bracket, and a through hole is opened on the back of the horizontal plate body for wires to pass through.

[0006] According to the above technical solution, the vertical reflector includes a vertical plate body, a toothed shaft tube connected to the bottom of the vertical plate body, a drive motor fixedly connected inside the front shell, the front of the drive motor meshing with the teeth of the toothed shaft tube, and a notched tube with a through hole on the back connected to the bottom of the toothed shaft tube.

[0007] According to the above technical solution, the reflection adjustment component also includes an edge light strip, which is an LED light strip and is fixedly connected to the outer edge of the horizontal plate and the vertical plate, respectively. The edge light strip is electrically connected to the control module and is used to indicate the approximate direction of the remote control.

[0008] According to the above technical solution, clamping frames are provided on both the left and right sides of the set-top box body. The clamping frame includes a sliding plate that is slidably connected to one side of the set-top box body by a spring. A pulling frame is fixedly connected to the outer end of the sliding plate, and a contact plate for clamping the set-top box body is fixedly connected to the top of the pulling frame.

[0009] According to the above technical solution, a contact seat is connected to the top of the set-top box body. The contact seat is located on the top of the base and has a through hole. A cooling fan is connected to the back of the set-top box body. The cooling fan is used to exhaust hot air from inside the base.

[0010] According to the above technical solution, the induction antennas are fixedly connected to the front of the horizontal plate and the vertical plate, respectively. The control module determines the location of the remote control by analyzing the signal strength received by the induction antennas at different positions, and verifies the reflection effect by monitoring the command execution status of the set-top box.

[0011] A method for optimizing the remote control signal of a set-top box signal reflector includes the following steps: Step S1: Signal acquisition. The induction antenna in the reflection adjustment component receives the infrared signal emitted by the remote control in real time and converts the signal strength data into an electrical signal to feed back to the control module. Step S2: Direction determination. The control module analyzes and compares the signal strength data fed back by the sensing antennas at different locations, and determines the spatial azimuth angle range of the remote controller through the signal strength gradient distribution pattern. Step S3: Attitude adjustment. The control module generates drive control commands based on the determined remote control position and the fixed geometric relationship between the reflector and the signal receiving window of the set-top box. It controls the extension and retraction of the stepper rod corresponding to the horizontal reflector and the rotation of the drive motor corresponding to the vertical reflector, thereby adjusting the tilt angle of the horizontal plate and the deflection angle of the vertical plate so that the infrared signal is reflected by the reflector and points to the signal receiving window of the set-top box. Step S4: Effect verification. The control module monitors the execution status of the remote control command of the set-top box in real time. If the command is not executed effectively, it is determined that the reflection posture is not optimal. The system returns to step S3 and fine-tunes the reflector posture within the preset angle neighborhood until the set-top box successfully responds to the command and locks the optimal reflection posture.

[0012] According to the above technical solution, step S3 also includes a positioning prompt step: the control module converts the signal strength vector collected by the induction antenna into a light intensity control signal for the edge light strip through a mapping function. The higher the signal strength, the brighter the edge light strip in the corresponding area, and the edge light strip section of the reflector corresponding to the remote control position is lit synchronously to prompt the user for the optimal aiming direction of the remote control; the attitude fine-tuning in step S4 adopts a gradient search algorithm. Starting from the current reflector attitude, the horizontal plate tilt angle and the vertical plate deflection angle are iteratively adjusted according to a preset step size until the command execution conditions are met.

[0013] According to the above technical solution, it also includes device adaptation and intelligent heat dissipation steps: A: The device is adapted by pulling the clamping frame to both sides, which causes the sliding plate to compress the return spring. After placing the set-top box body on the top of the contact seat, the pull frame is released. The spring return force pushes the contact plate to clamp the two sides of the set-top box body, thus achieving the adaptation and fixing of set-top boxes of different width specifications. B: Intelligent heat dissipation. The control module collects the internal temperature data of the base in real time through the temperature sensor. When the temperature is ≥45℃, the cooling fan is started and adjusted to the corresponding speed to exhaust hot air. When the temperature is ≤35℃, the cooling fan is controlled to reduce speed or stop running. The internal temperature of the base is kept stable through dual threshold hysteresis control.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The device in this invention captures and reflects infrared signals from all directions using a multi-dimensional inductive antenna array and an adaptive reflection adjustment mechanism. Combined with closed-loop optimized control, it completely eliminates blind spots in set-top box signal reception, achieving a remote control command response rate of over 99%. Simultaneously, the brightness gradient and directional illumination design of the edge light strip intuitively guides the user's aim, enabling rapid positioning. Its flexible clamp can accommodate set-top boxes of different widths, making installation convenient and without damaging the equipment. The heat dissipation system, composed of thermally conductive silicone and an intelligent temperature-controlled cooling fan, ensures stable temperature while also being energy-efficient. The device also features overload and short-circuit protection and anti-interference signal processing functions. Its lightweight and safe structure, compact design, and simple assembly make it suitable for various scenarios, demonstrating outstanding practicality and promotional value.

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

[0018] Example 1 like Figures 1 to 6 As shown, the set-top box signal reflector disclosed in this invention facilitates remote control positioning. Its core components include a set-top box body 1, a base 2, a reflection adjustment component 3, an upper shell 4, a front shell 5, a clamping frame 6, a control module 7, and an auxiliary function module. The components work together to achieve comprehensive functions such as signal reflection, positioning prompts, device fixation, and heat dissipation.

[0019] like Figure 2As shown, the set-top box body 1 serves as the core for signal processing and instruction execution. Its back panel integrates a USB interface, power interface, video interface, and network interface, providing basic support for device connection, signal transmission, and power supply. A base 2 is bolted to the bottom of the set-top box body 1. The base 2 is made of high-strength engineering plastic and is integrally molded, combining structural stability and lightweight characteristics. A metal mounting bracket 21 is welded to the front of its inner wall, providing stable support for the assembly of the reflection adjustment component 3. The reflection adjustment component 3 is mounted on the front of the base 2. An upper shell 4 is bolted to the top of the base 2, covering the top of the set-top box body 1, forming top protection and structural limitation for the set-top box body 1, while also providing an installation carrier for the top horizontal reflector 31. A front shell 5 is integrally molded on the front of the set-top box body 1. The front shell 5 has a pre-reserved mounting cavity for the drive motor 323, providing assembly space for the transmission mechanism of the vertical reflector 32.

[0020] like Figure 4 As shown, the reflection adjustment component 3, as the core functional module of the present invention, integrates a horizontal reflector 31, a vertical reflector 32, an induction antenna 33, and an edge light strip 34 to form a multi-dimensional signal capture and reflection system. Two transverse reflectors 31 are provided, symmetrically mounted on the front of the base 2 and the front of the upper shell 4 respectively. Each transverse reflector 31 includes a transverse plate 311. The transverse plate 311 is made of aluminum alloy substrate and coated with a high reflectivity metal coating, with a reflectivity of over 95%, ensuring efficient reflection of infrared signals. The back of the transverse plate 311 has wire through holes for the connecting wires of the induction antenna 33 and the edge light strip 34 to pass through, avoiding wire entanglement that affects structural movement. The back of the transverse plate 311 is hinged to four stepping rods 312. The four stepping rods 312 are evenly distributed in a rectangular array, and their ends are fixed to the outer surface of the mounting bracket 21 by bolts. Through the precise extension and retraction of the stepping rods 312, the tilt angle of the transverse plate 311 can be adjusted within the range of 0-45° to meet the signal reflection requirements of different directions.

[0021] like Figure 5As shown, two vertical reflectors 32 are also provided, symmetrically distributed on the left and right sides of the set-top box body 1. Each vertical reflector 32 includes a vertical plate body 321, the material of which is consistent with that of the horizontal plate body 311 to ensure the consistency of signal reflection performance. A geared tube 322 is integrally formed at the bottom of the vertical plate body 321. A drive motor 323 is fixedly connected to the inside of the front shell 5 through a bracket. A gear is fixedly connected to the output shaft of the drive motor 323. The gear meshes with the teeth on the outer wall of the geared tube 322 to form a high-precision gear transmission mechanism. A notched tube 324 is integrally formed at the bottom of the geared tube 322. A wire through hole is opened on the back of the notched tube 324 for the wires of the induction antenna 33 and the edge light strip 34 on the vertical plate body 321 to pass through. The forward and reverse rotation of the drive motor 323 drives the geared tube 322 to rotate, thereby driving the vertical plate body 321 to deflect within the range of -30° to 30° around the rotation axis at the top of the front shell 5, so as to achieve precise control of the horizontal signal reflection angle.

[0022] The induction antenna 33 is a miniature infrared receiving antenna, rationally configured in number according to the size of the reflector, and evenly fixed to the front of the horizontal plate 311 and the vertical plate 321 to form an all-round signal capture array, ensuring comprehensive coverage of the infrared signals of the remote control from different directions. The induction antenna 33 is electrically connected to the control module 7 through a shielded wire. The shielding layer can effectively resist environmental electromagnetic interference and ensure the stability of signal transmission. The edge light strip 34 uses a low-power LED light strip, which is embedded and fixed along the outer edge of the horizontal plate 311 and the vertical plate 321. Its control end is electrically connected to the control module 7, and can realize three-level brightness gradient adjustment according to the signal strength received by the induction antenna 33. The light strip section corresponding to the remote control's direction will light up synchronously, providing users with intuitive and accurate aiming direction prompts and greatly reducing the difficulty of operation.

[0023] like Figure 1 As shown, the set-top box body 1 is equipped with elastic clamping frames 6 on both the left and right sides. Each clamping frame 6 includes a sliding plate 61, which is slidably connected to the side of the set-top box body 1 via a sliding guide rail. A return spring is provided between the sliding plate 61 and the set-top box body 1, with its two ends fixed to the inner side of the sliding plate 61 and the side of the set-top box body 1, respectively, providing good elastic recovery performance. A pull frame 62 is welded to the outer end of the sliding plate 61. A weight-reducing through hole is provided on one side of the pull frame 62, which reduces the structural weight and facilitates user operation. A contact plate 63 is fixed to the top of the pull frame 62 by bolts. An anti-slip rubber pad is adhered to the inner side of the contact plate 63, and the surface of the rubber pad has anti-slip texture. While achieving elastic clamping and fixing of the set-top box body 1, it can effectively prevent excessive clamping force from scratching the set-top box shell. Through the elastic extension and contraction of the return spring, the clamping frame 6 can be adapted to mainstream set-top box models with a width range of 8-15cm, significantly improving its versatility.

[0024] like Figure 3As shown, a control module 7 is fixed to the bottom of the inner wall of the set-top box body 1 via a shock-absorbing bracket. This control module 7 uses a high-performance STM32 series microcontroller (MCU) and integrates a signal processing unit, a drive control unit, a status monitoring unit, and a temperature detection unit, forming a complete control core. The signal processing unit receives infrared signals transmitted by the induction antenna 33 and accurately determines the spatial orientation of the remote control using a signal strength comparison algorithm. The drive control unit generates PWM control signals based on the orientation information, adjusting the extension and retraction of the stepper push rod 312 and the rotation angle of the drive motor 323 to achieve dynamic optimization of the reflector's posture. The status monitoring unit receives real-time command execution status signals from the set-top box body 1, forming a closed-loop control. If a command is not effectively executed, the reflector angle is automatically fine-tuned until the optimal reflection effect is achieved. The temperature detection unit collects real-time internal temperature data of the base 2 through a temperature sensor, providing a basis for heat dissipation control. The control module 7 is electrically connected to the stepper push rod 312, the drive motor 323, the induction antenna 33, the edge light strip 34, and the cooling fan 8 via wires, constructing a complete functional control link.

[0025] like Figure 2 As shown, the auxiliary function module includes a cooling fan 8, a contact base 9, a USB connector 10, and a power plug 11. The contact base 9 is fixed to the top of the set-top box body 1, made of thermally conductive silicone, and has multiple heat dissipation holes on its top. Its bottom is connected to the inside of the base 2, which can quickly conduct heat generated by the set-top box body 1. The cooling fan 8 is fixed to the back of the set-top box body 1 and is an intelligent temperature-controlled fan. Its control terminal is electrically connected to the control module 7. When the internal temperature of the base 2 exceeds 45°C, the control module 7 automatically starts the cooling fan 8 and adjusts it to the corresponding speed to expel hot air. When the temperature drops below 35°C, the speed is reduced or the operation is stopped, achieving efficient and energy-saving heat dissipation. The USB connector 10 is detachably connected to the USB interface on the back of the set-top box body 1, which not only realizes the electrical connection between the control module 7 and the set-top box, but also transmits the working status signal of the set-top box, realizing the linkage between the two. The power plug 11 integrates overload protection and short-circuit protection functions, is electrically connected to the control module 7, and provides a stable and safe power supply for the entire device.

[0026] Example 2 This embodiment is a further refinement of Embodiment 1. This embodiment provides a specific implementation method for a reflector.

[0027] The user first pulls the sliding plate 61 to both sides using the pull bracket 62, causing the sliding plate 61 to slide outward along the sliding guide rail and compress the return spring. At this time, the contact plate 63 separates simultaneously, forming a clamping space suitable for placing the set-top box. The set-top box body 1 is then placed stably on top of the contact seat 9, ensuring that the bottom of the set-top box body 1 is fully in contact with the contact seat 9 to guarantee heat conduction efficiency. After releasing the pull bracket 62, the return spring pushes the sliding plate 61 inward under the action of elastic restoring force, causing the contact plate 63 to tightly fit against both sides of the set-top box body 1. Stable clamping is achieved through the anti-slip rubber pads on the inner side of the contact plate 63, preventing device displacement. After assembly, the USB connector 10 is inserted into the USB interface on the back of the set-top box body 1 to realize the electrical connection and signal transmission between the control module 7 and the set-top box. Then, the power plug 11 is connected to an external AC socket to complete the power supply connection of the entire device. At this time, the device enters standby mode.

[0028] like Figure 6 As shown, during operation, when the user controls the remote control to emit an infrared control signal, the array of induction antennas 33 distributed on the front of the horizontal plate 311 and the vertical plate 321 will fully capture the signal and convert it into an electrical signal, which is then transmitted to the signal processing unit of the control module 7 through shielded wires. The signal processing unit analyzes and compares the electrical signal strength transmitted by each induction antenna 33, uses a directional recognition algorithm to accurately determine the spatial orientation of the remote control, and transmits the orientation data to the drive control unit. The drive control unit generates corresponding control commands based on the orientation data, outputs PWM adjustment signals to the stepper push rod 312, controls the extension and retraction of the stepper push rod 312 to adjust the tilt angle of the horizontal plate 311, and simultaneously outputs forward and reverse control signals to the drive motor 323. Through the meshing transmission of the gear and gear shaft tube 322, the vertical plate 321 is driven to deflect, so that the reflective surfaces of the horizontal plate 311 and the vertical plate 321 are accurately aligned with the orientation of the remote control, ensuring that the infrared signal is efficiently reflected to the signal receiving window of the set-top box body 1.

[0029] During signal reflection adjustment, the status monitoring unit of control module 7 receives real-time command execution status signals from set-top box body 1. If the command is not effectively executed, it indicates that the reflection angle has not reached the optimal level. Control module 7 will automatically fine-tune the operating parameters of stepper push rod 312 and drive motor 323 until set-top box body 1 successfully responds to the remote control command, completing the closed-loop verification and optimization of the reflection effect. At the same time, under the control of control module 7, the edge light strip 34 exhibits three levels of brightness change according to the signal strength received by induction antenna 33. The stronger the signal, the brighter the light strip. The edge light strip 34 section corresponding to the remote control's position is also illuminated synchronously, providing users with intuitive alignment guidance and helping them quickly adjust the remote control position to the optimal operating angle.

[0030] During long-term operation, the heat generated by the set-top box body 1 is quickly conducted to the contact seat 9 through the contact surface, and then dissipated into the base 2 through the heat dissipation holes on the top of the contact seat 9. The temperature detection unit of the control module 7 collects the internal temperature data of the base 2 in real time through the temperature sensor. When the temperature exceeds the preset threshold of 45°C, the control module 7 outputs a start signal to the cooling fan 8, controlling the cooling fan 8 to run at the corresponding speed to expel the hot air inside the base 2. When the temperature drops below the preset safety threshold of 35°C, the control module 7 controls the cooling fan 8 to reduce its speed or stop running, realizing intelligent temperature control and heat dissipation, which not only ensures the stability of equipment operation, but also reduces energy consumption.

[0031] The clamping frame 6 of this device can be adapted to mainstream set-top box models with a width ranging from 8 to 15 cm through the elastic adjustment of the return spring. The anti-slip rubber pad on the inner side of the contact plate 63 effectively avoids scratching damage to the set-top box shell during clamping. The high-reflectivity metal coating used on the horizontal plate 311 and the vertical plate 321 ensures the infrared signal reflection efficiency. The anti-interference processing unit integrated in the control module 7 can effectively filter infrared interference signals in the environment and ensure accurate identification of remote control signals. The overload protection and short circuit protection functions integrated in the power plug 11 can quickly cut off the power supply when the circuit is abnormal, ensuring the safety of the equipment and the user.

[0032] Example 3 This embodiment is a further refinement of Embodiment 2. It focuses on the core operating process of the device. When the user controls the remote control to emit an infrared control signal, the array of induction antennas 33 distributed on the front of the horizontal plate 311 and the vertical plate 321 fully captures the signal and converts it into an electrical signal, which is then transmitted to the signal processing unit of the control module 7 via shielded wires. The signal processing unit analyzes and compares the electrical signal strength transmitted by each induction antenna 33, accurately determines the spatial orientation of the remote control using an orientation recognition algorithm, and transmits the orientation data to the drive control unit. The drive control unit generates corresponding control commands based on the orientation data, outputs a PWM adjustment signal to the stepper lever 312, controls the extension and retraction of the stepper lever 312 to adjust the tilt angle of the horizontal plate 311, and simultaneously outputs forward and reverse control signals to the drive motor 323. Through the meshing transmission of the gear and gear shaft tube 322, the vertical plate 321 is driven to deflect, ensuring that the reflective surfaces of the horizontal plate 311 and the vertical plate 321 are precisely aligned with the remote control's orientation, ensuring that the infrared signal is efficiently reflected to the signal receiving window of the set-top box body 1. During signal reflection adjustment, the status monitoring unit of control module 7 receives real-time command execution status signals from set-top box body 1. If the command is not effectively executed, it indicates that the reflection angle has not reached the optimal level. Control module 7 will automatically fine-tune the operating parameters of stepper push rod 312 and drive motor 323 until set-top box body 1 successfully responds to the remote control command, completing the closed-loop verification and optimization of the reflection effect. At the same time, under the control of control module 7, the edge light strip 34 exhibits three levels of brightness change according to the signal strength received by induction antenna 33. The stronger the signal, the brighter the light strip. The edge light strip 34 section corresponding to the remote control's position is also illuminated synchronously, providing users with intuitive aiming direction guidance. During operation, the heat generated by the set-top box body 1 is quickly conducted to the contact seat 9 through the contact surface, and then dissipated into the base 2 through the heat dissipation holes on the top of the contact seat 9. The temperature detection unit of the control module 7 collects the internal temperature data of the base 2 in real time through the temperature sensor. When the temperature exceeds the preset threshold of 45°C, the control module 7 outputs a start signal to the cooling fan 8, controlling the cooling fan 8 to run at the corresponding speed to expel the hot air inside the base 2. When the temperature drops below the preset safety threshold of 35°C, the control module 7 controls the cooling fan 8 to reduce its speed or stop running, realizing intelligent temperature control and heat dissipation.

[0033] Example 4 This embodiment is a further refinement of Embodiment 3, focusing on an in-depth explanation of the core technical principles, related mathematical models, and technical advantages of the present invention, so as to fully present the innovation of the technical solution.

[0034] like Figure 7As shown, the core innovation of this invention lies in constructing a dynamic, adaptive, closed-loop controlled infrared signal enhancement and guidance system. This system overcomes the limitations of traditional fixed signal receiving devices by employing a three-pronged approach of spatial signal field perception, optimal reflection path calculation, and real-time attitude adjustment, fundamentally solving the signal reception blind zone problem of the fixed-installation set-top box 1. In the spatial signal field perception and modeling stage, a discrete sampling point array is formed by multiple inductive antennas 33 arranged in different spatial orientations towards the front of the reflector. This array can comprehensively sample the spatial infrared signal intensity centered on the set-top box 1, forming a perception network covering the forward hemisphere. From a physical model perspective, the remote control can be approximated as a point-like infrared source. The signal intensity emitted by the remote control attenuates with propagation distance in free space. Since the physical dimensions of the reflector and its relative position to the receiving window of the set-top box 1 are fixed, the signal intensity received by each inductive antenna 33 can be modeled as the spatial azimuth angle of the remote control. The function of distance r is shown below: in It is the horizontal azimuth. The vertical pitch angle is used. The signal processing unit of the control module 7 does not rely on absolute distance r for positioning. Instead, it collects the signal strength of each induction antenna 33 in real time to form a signal strength vector. By analyzing the distribution pattern of this vector, the azimuth angle range of the signal source can be relatively determined. This is because for an array of induction antennas 33 with a fixed geometric configuration, changes in the direction of the signal source will cause the received intensity of each antenna to exhibit a specific and identifiable gradient change pattern, thereby providing a precise azimuth basis for subsequent reflection adjustment.

[0035] Based on the above-mentioned spatial signal field perception and modeling results, the dynamic optimization mechanism for the reflection path of this invention further realizes the precise guidance of the signal. The lateral reflector 31 and the vertical reflector 32 together constitute a two-dimensional adjustable composite reflective surface. Its adjustment process strictly follows the law of reflection, that is, the incident angle of the infrared signal equals the reflection angle. The adjustment goal is to ensure that the reflected beam ultimately converges precisely onto the infrared receiving window of the set-top box body 1. The control module 7 determines the direction based on the estimated remote control direction. Based on the known fixed geometric relationship between the reflector and the set-top box receiving window, the target tilt angle of the horizontal plate 311 that theoretically optimizes the reflected light path is calculated through reverse derivation. and vertical plate body 321 target deflection angle Under the command of the drive control unit, the driving component precisely pushes the reflector to adjust its attitude towards the target pose, ensuring maximum signal reflection efficiency. To address environmental interference and calculation errors in practical applications, this invention innovatively introduces a closed-loop feedback and adaptive iterative optimization mechanism, using the set-top box's command execution state as a direct feedback variable for system performance, thus forming a high-order closed-loop control system. If the set-top box does not respond to the command after the reflector is adjusted to the initial calculated pose, it indicates that the actual optical path is not optimal. At this point, the system automatically enters the iterative optimization stage, and control module 7 adjusts the reflector to the current pose. Starting from the pre-defined small neighborhood Inside, the angle of the reflector is fine-tuned using optimization algorithms such as gradient search, and the execution status of the instructions is continuously monitored until the instructions are successfully executed, thus locking the current pose as the optimal solution. This process enables the system to learn and adapt to non-ideal environments, significantly improving the robustness of the technical solution. At the human-computer interaction level, this invention employs a multimodal user guidance strategy. The on / off state and brightness changes of the edge light strip 34 are not simply decorative functions, but rather a visual mapping of the spatial signal field strength distribution. The control module 7 uses the mapping function G to map the signal strength vector collected by the array of induction antennas 33. Converted to the light intensity vector of the corresponding light strip segment ,Right now The design of this function ensures that the reflector edge area corresponding to the direction of the strongest signal obtains the highest visual salience, such as the highest brightness or special lighting mode, realizing intuitive guidance from the invisible infrared signal space to the visible light cues, which conforms to human spatial cognition habits.

[0036] To more accurately describe the internal logic of the technical solution of this invention, the following related mathematical model is constructed as theoretical support. In the signal orientation sensing model, there are N induction antennas 33 in total, and the spatial unit direction vector of the i-th antenna is...

[0037] Based on the above technical principles and mathematical models, this invention achieves a paradigm shift from passive reception to active capture and guidance compared to existing technologies, and has significant technical advantages. In terms of signal coverage, a virtual large-aperture signal receiving area is constructed through a dynamic reflective surface, theoretically covering the forward hemispherical space (limited by the mechanical adjustment range). This fundamentally eliminates signal dead zones caused by fixed installations, achieving omnidirectional coverage without blind spots. Regarding positioning accuracy and reliability, a dual guarantee of the effectiveness of reflection adjustment is achieved through relative orientation sensing based on array signal processing and closed-loop verification based on command execution feedback, resulting in a remote control command response rate of over 99%. In terms of human-computer interaction, the invisible signal field strength distribution is mapped into tangible, spatially corresponding light signals, greatly reducing the cognitive load and time cost for users to find the optimal operating angle, achieving an intuitive and efficient operating experience. Regarding system adaptability, the closed-loop optimization model enables the system to automatically compensate for installation errors, slight environmental changes, and individual hardware differences, exhibiting good robustness and universality, and adapting to different indoor layouts and set-top box installation locations. Regarding energy efficiency and safety, a physical model-based thermal management strategy minimizes standby power consumption of the heat dissipation function while ensuring stable core component temperatures. Simultaneously, the integrated electrical protection mechanism provides reliable assurance for the long-term safe operation of the equipment.
