Description

Technical Field

[0001] This utility model relates to the field of wireless remote control technology, and in particular to a remote control with encrypted communication transmission function. Background Technology

[0002] A remote control with encrypted communication transmission function is widely used in smart homes (ensuring the secure transmission of control commands for home devices), industrial automation (ensuring that remote device control data is not stolen), intelligent transportation (such as remote control of drones), and other fields. With the rapid development of Internet of Things technology and the popularization of smart homes and industrial control, remote controls, as the core tool for device control, face security risks such as data leakage and command tampering.

[0003] Traditional remote control communication methods are no longer sufficient to meet users' needs for data privacy and system security; at the same time, the requirements for remote control and multi-device compatibility are increasing in different scenarios. In previous technologies, when remote controls were used wirelessly, their signal transmission was easily intercepted, or different types of remote control signals could interfere with each other. Therefore, there is a need to develop a remote control with encrypted communication transmission capabilities. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a remote control with encrypted communication transmission function, which aims to improve the problems in the prior art where remote controls are mostly wireless, but the signal transmission of the remote control is easily intercepted, or different types of remote control signals may interfere with each other.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a remote control with encrypted communication transmission function, comprising a user input module, a main control MCU module, a feedback module, and an encryption module. The output terminal of the user input module is electrically connected to the input terminal of the main control MCU module. The main control MCU module is bidirectionally electrically connected to an interference detection module, a power management module, an environmental sensing module, a data storage module, and a multi-communication module. The output terminal of the main control module is electrically connected to the input terminal of the feedback module. The main control MCU module is bidirectionally electrically connected to the encryption module via a hardware security bus (HSM). The hardware security bus (HSM) includes differential signal pairs (impedance 100Ω±5%) and an electromagnetic shielding layer (thickness ≥2oz).

[0006] The above technical solution, which establishes bidirectional electrical connections between the main control MCU and each module, is essentially designed to enable bidirectional interaction between "control command issuance" and "status data feedback," upgrading the remote control from a "single command transmitter" to a "self-sensing and self-adjusting intelligent system." This design not only enhances functional flexibility (such as adaptive switching between multiple protocols) and security (such as real-time key interaction between the encryption module and the communication module), but also ensures the system's stability in complex environments through a "feedback closed loop," making it a core architectural feature of intelligent and networked remote controls.

[0007] As a further description of the above technical solution: The multi-communication module integrates a 4G / 5G communication unit, a Bluetooth communication unit, and an infrared communication unit.

[0008] The above technical solutions cover wide area networks (4G / 5G), short-range wireless (Bluetooth), and traditional infrared communication, adapting to diverse devices and scenarios.

[0009] As a further description of the above technical solution: The multiple communication modules are connected to external devices.

[0010] The above technical solution achieves end-to-end data security protection from "communication protocol → encryption processing → external device", ensuring that data transmitted by different communication units is processed by the encryption module.

[0011] As a further description of the above technical solution: The communication data between the multiple communication modules and external devices must be forwarded and encrypted by the main control MCU module.

[0012] The above technical solutions ensure that data transmission is not easily eavesdropped, tampered with, or forged. For example, when remotely controlling devices via 4G / 5G, commands are encrypted by an encryption module before being sent, and decrypted upon receipt by the external device, preventing hackers from intercepting control signals.

[0013] As a further description of the above technical solution: The feedback module includes a screen backlight driving circuit, and the output terminal of the main control MCU module is electrically connected to the control signal input terminal of the screen backlight driving circuit through a PWM signal line.

[0014] The above technical solution enables dynamic adjustment of screen backlight brightness, allowing users to adjust brightness according to usage needs (such as energy saving and visibility under strong light) or user settings, thereby improving the user's visual experience and reducing unnecessary power consumption.

[0015] As a further description of the above technical solution: The power management module is electrically connected to the multi-communication module and the feedback module.

[0016] The above technical solution can rationally allocate power, avoid shortening the remote control's battery life due to excessive power consumption of the module, and control the module to reduce power consumption when the battery is low (such as reducing backlight brightness and turning off unnecessary communication units), thereby extending the device's usage time and ensuring the operation of core functions.

[0017] As a further description of the above technical solution: The environmental sensing module includes a light sensor and a temperature sensor.

[0018] The above technical solution can collect real-time light intensity and temperature data in the environment, providing the remote control with rich environmental information. It can automatically adjust the screen backlight brightness according to the light intensity, optimize the user's visual experience and reduce energy consumption. Combined with temperature data, it can assist the power management module in adjusting the device's power consumption, avoiding performance degradation caused by high temperature or abnormalities caused by low temperature.

[0019] As a further description of the above technical solution: The light sensor is connected to the main control MCU module via an I²C bus, and the temperature sensor is connected to the main control MCU module via a single-bus communication.

[0020] The above technical solutions ensure efficient and stable transmission of environmental data to the main control MCU module, enabling the main control MCU module to quickly process the data and realize automated functions, such as automatically adjusting the screen backlight brightness according to the light intensity, or optimizing power management strategies based on temperature data.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the remote control, through the architecture design of "main control + encryption + multiple auxiliary modules", achieves multiple optimizations in functionality, adaptability and user experience on the basis of ensuring communication security. It is especially suitable for scenarios with high requirements for data security and environmental compatibility. Through hardware-level signal isolation and modular collaboration, a secure, low-power and highly reliable encrypted communication remote control architecture is realized.

[0022] 2. In this utility model, the environmental sensing module provides environmental data support for the remote control, enabling it to sense changes in the external environment and providing basic data for intelligent control. By integrating 4G / 5G, Bluetooth, and infrared, combined with the full-link protection of the encryption module, it achieves multi-scenario coverage of "long-distance wide-area communication + short-distance high-speed interaction + compatibility with traditional devices", while ensuring the security of data transmission in each scenario.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 This utility model provides an embodiment of a remote control with encrypted communication transmission function, including a user input module, a main control MCU module, a feedback module, and an encryption module. The output terminal of the user input module is electrically connected to the input terminal of the main control MCU module. The main control MCU module is bidirectionally electrically connected to an interference detection module, a power management module, an environmental sensing module, a data storage module, and a multi-communication module. The output terminal of the main control module is electrically connected to the input terminal of the feedback module. The main control MCU module is bidirectionally electrically connected to the encryption module through a hardware security bus (HSM). The hardware security bus (HSM) includes differential signal pairs (impedance 100Ω±5%) and an electromagnetic shielding layer (thickness ≥2oz). Specifically, the user input module transmits physical button / touch commands to the main control MCU module. The main control MCU module processes user input signals, coordinates the work of various modules, executes instruction logic and data operations, ensuring the orderly operation of all functional modules in the remote control, and realizing instruction parsing, processing, and distribution. The encryption module communicates with the main control MCU via the Hardware Security Bus (HSM) to encrypt / decrypt transmitted data. The feedback module provides feedback to the user through visualization, sound, or vibration, enhancing the user experience, such as button light indicators and sound effects. The power management module provides power to the necessary modules, and the main control MCU module can dynamically adjust the power supply strategy of each module by controlling the power management module. The data storage module stores encrypted configurations and operation logs. The main control module sends control commands such as "start detection" and "switch frequency band" to the interference detection module, actively triggering the interference detection task. The interference detection module can then... The system provides real-time detection data (such as interference intensity and frequency band occupancy) to the main control MCU module, providing decision-making basis for the main control (such as whether to switch communication protocols). The main control module can send control commands to the environmental sensing module to activate or put sensors into sleep mode as needed, reducing power consumption. The environmental sensing module can provide environmental data back to the main control module, providing a basis for control logic. The bidirectional connection between the data storage module and the main control MCU module allows the main control MCU to update or read stored data at any time. At the same time, the data storage module can also provide feedback on anomalies (such as storage errors) to the main control MCU module, ensuring data reliability. Through the bidirectional connection between the main control MCU module and multiple communication modules, the main control MCU can select the communication protocol according to needs (such as Bluetooth for short distances and Wi-Fi for long distances) and encrypt the transmitted data through the encryption module. At the same time, the communication modules provide real-time feedback on the link status, and the main control MCU module can switch protocols or retransmit data accordingly (such as automatically switching to the infrared channel when Bluetooth connection is lost), ensuring communication stability. Through the central coordination and hardware-level optimization of the main control MCU, breakthrough improvements in communication security, environmental adaptability, and energy efficiency have been achieved.

[0026] Reference Figure 1 The multi-communication module integrates a 4G / 5G communication unit, a Bluetooth communication unit, and an infrared communication unit; Specifically, it provides wide-area mobile network access through the 4G / 5G communication unit, supports remote control and data backhaul, supports short-range low-power device connection through the Bluetooth communication unit, and is suitable for reliable short-range communication with electromagnetic interference resistance through the infrared communication unit. By integrating multiple communication technologies, it supports different network standards and transmission protocols, improving the versatility and compatibility of the remote control.

[0027] Reference Figure 1 The multiple communication modules are connected to external devices; the communication data between the multiple communication modules and the external devices must be forwarded and encrypted by the main control MCU module. Specifically, the encryption module can monitor channel security in real time, achieving end-to-end hardware-level encryption, dynamic key management, and protocol attack interception. While ensuring seamless switching of multi-mode communication (4G / Bluetooth / infrared), it can reduce the risk of key leakage to zero. Through the dynamic switching of communication among the three communication modules in the encryption module, the remote control can have 5G remote control, Bluetooth smart interconnection, and infrared anti-interference capabilities.

[0028] Reference Figure 1 and Figure 2 The feedback module includes a screen backlight driving circuit, and the output of the main control MCU module is electrically connected to the control signal input of the screen backlight driving circuit through a PWM signal line; the power management module is electrically connected to the multi-communication module and the feedback module; the environmental sensing module includes a light sensor and a temperature sensor; the light sensor is connected to the main control MCU module through an I²C bus, and the temperature sensor is connected to the main control MCU module through a single bus. Specifically, the main control MCU module can control the screen backlight drive circuit through pulse width modulation (PWM) signals to adjust the screen backlight brightness. The power management module can uniformly manage the power supply of multiple communication modules and feedback modules and monitor their power usage status. The environmental sensing module collects light intensity and temperature data in the environment through light sensors and temperature sensors. By defining the data transmission method between the light sensors, temperature sensors and the main control MCU module, the I²C bus is suitable for low-speed communication between multiple devices, and the single bus simplifies the connection of temperature sensors.

[0029] Working Principle: First, the user input module receives operation commands via buttons and transmits them to the main control MCU module. Then, the main control MCU module monitors the communication environment in real time through a bidirectional interference detection module, dynamically adjusts anti-interference strategies, and interacts with the power management module to optimize power consumption. It also coordinates the dynamic channel switching of multiple communication modules (4G / 5G / Bluetooth / Infrared). The power management module allocates power to other modules as needed. Light and temperature data collected by the environmental sensing module (light sensor + temperature sensor) are processed by the MCU and drive the feedback module to implement PWM dimming. The main control MCU module works bidirectionally with the encryption module through the Hardware Security Bus (HSM) to ensure data transmission security. The processed secure data is parsed by the main control MCU and drives the feedback module to provide visual interaction to the user. At the same time, encrypted commands are transmitted to external devices through multiple communication modules (4G / 5G / Bluetooth), thus forming a complete closed-loop control from input to output, achieving an intelligent and secure device operation experience.
