Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental monitoring equipment technology, specifically to a LORA safety monitoring device based on remote wake-up. Background Technology
[0002] In high-risk working environments such as tunnels and coal mines, real-time monitoring of environmental parameters such as gas concentration, temperature, humidity, smoke, and harmful particles is often required to ensure operational safety. However, these areas are generally characterized by difficulties in long-term personnel presence, unstable power supply, and complex communication environments, thus placing high demands on the reliability, low power consumption, and remote communication capabilities of monitoring devices. Existing environmental monitoring devices generally rely on manual button activation, requiring personnel to be on-site and physically operate the equipment to activate it. This method is inefficient in daily management and cannot be activated promptly in emergency situations, posing significant safety hazards. To improve automation, some systems have introduced automatic triggering mechanisms based on geological disaster early warning signals, enabling automatic data collection and transmission when anomalies are detected. However, this approach is somewhat passive; the system remains idle when no obvious signs appear, failing to proactively acquire on-site information and hindering pre-disaster assessment and hazard identification. Utility Model Content
[0003] The purpose of this utility model is to provide a LORA safety monitoring device based on remote wake-up that is particularly suitable for high-risk, unattended areas such as tunnels and coal mines. While ensuring timely data acquisition and reliable communication, it significantly reduces the overall power consumption of the equipment and improves the practicality and deployment flexibility of the system, thereby solving at least one of the technical problems existing in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model provides a LoRa security monitoring device based on remote wake-up, comprising:
[0006] A main control module; a sensor group module connected to the main control module; a LoRa communication module connected to the main control module, the LoRa communication module being connected to a monitoring terminal; a power supply module connected to the main control module, the LoRa communication module, and the sensor group module; and a remote control receiver module connected to the power supply module and the remote control.
[0007] Furthermore, the power module includes a power control unit and a power supply unit; the power supply unit is connected to the main control module, the sensor group module and the LORA communication module; the remote control receiving module is connected to the power control unit.
[0008] Furthermore, the sensor module includes at least one sensor connected to the power supply unit.
[0009] Terminology Explanation: In high-risk, unattended areas such as tunnels and coal mines, this paper proposes a LORA (Long Range Radio) safety monitoring device based on remote wake-up, addressing the problems of existing environmental monitoring equipment, such as limited start-up methods, excessive power consumption, and unstable communication. LORA is a low-power long-range wireless communication technology characterized by high receiving sensitivity. The main advantages of LORA technology are low power consumption, long-distance transmission, and strong anti-interference capabilities. Under the same power consumption conditions, the transmission distance of LORA modules far exceeds that of traditional Wi-Fi and Bluetooth technologies, making it widely applicable in the Internet of Things (IoT) field.
[0010] The beneficial effects of this invention are as follows: Remote control of the monitoring device eliminates the need for close-range manual operation, improving safety and flexibility. The remote control receiver module operates continuously with extremely low power consumption, while other modules are powered only when needed, significantly reducing energy consumption and making it suitable for long-term battery-powered applications. LoRa communication offers long-range, low-power, and high-reliability characteristics, suitable for data transmission needs in complex terrains and shielded environments. Simultaneously, the phased power supply strategy further refines energy management, extends the system's operating cycle, and reduces maintenance frequency and costs. The overall system structure is simple, with clear control logic, making it easy to deploy and expand, suitable for intelligent monitoring tasks in various high-risk, enclosed, and weak signal environments. This device solves key problems of existing environmental monitoring devices in high-risk locations, such as high power consumption, weak communication, and inconvenient control, and has significant practical application value.

[0026] Those skilled in the art should understand that the accompanying drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily essential for implementing this utility model.
[0027] The core innovation of this invention lies in the collaborative design of remote control commands and low-power control logic, as well as the implementation mechanism of a phased power supply strategy. The device mainly comprises the following components: a remote control receiving module (ultra-low power consumption, continuously maintaining standby mode, capable of continuously receiving external signals to ensure stable and smooth operation); a power control module (capable of accurately transporting the power required by each module with extremely low power transmission delay, ensuring smooth operation of the entire device and enabling it to effectively adapt to various complex and dangerous scenarios); and a main control processing module (containing preset programs, capable of effectively collecting signals from various sensors, processing and filtering the collected signals, and saving them in a standard structured information frame format, which is beneficial to the normal operation of the entire device. After data transmission is complete, the entire device except the remote control receiving module can be powered off, which helps extend the lifespan of the device). The entire device has a long service life, enabling it to adapt to various complex environments. It includes multiple environmental sensor modules (capable of receiving various signals from the environment, such as temperature, humidity, CO / CH4 gas concentration, smoke, tilt angle, etc., and accurately transmitting them to the main control processing module, ensuring the sensitivity and accuracy of the device, and greatly improving the safety and reliability of the device) and a LoRa wireless communication module (ensuring the stability of the data transmission process, while also ensuring the speed of data transmission, the accuracy of the transmission location, and the responsiveness of each device, and basically eliminating interference from environmental factors in the tunnel mining area). The modules cooperate with each other through control logic and power management strategies to achieve the functional flow of remote wake-up, staged power supply, data acquisition, and remote communication.
[0028] The safety monitoring device based on remote control and LoRa includes the following steps:
[0029] S1. System Standby Monitoring Phase. After deployment, the device defaults to ultra-low power standby mode, where the remote control receiver module remains continuously powered on, employing an ultra-low power design to monitor control signals from the external remote control in real time. Other modules (including the main control MCU, sensors, communication modules, etc.) are powered off and do not generate additional energy consumption.
[0030] S2, Remote Control Wake-up Phase. When a monitoring personnel sends an activation signal using a remote control from a distance, the remote control receiver module recognizes the valid signal and inputs the wake-up command to the power control module. The power control module supplies power to each internal functional unit sequentially according to the set logic, first waking up the main control processing unit, and then controlling the activation of the corresponding sensor modules and LoRa communication modules. The entire wake-up and power supply process is precisely controlled with extremely low latency, meeting the needs of rapid on-site response.
[0031] S3. Data Acquisition and Processing Stage. After power-on, the main control module automatically loads the preset program to acquire data from various connected sensors (such as temperature and humidity, CO / CH4 gas concentration, smoke, tilt angle, etc.) and performs preliminary data cleaning and formatting. The processed data is encapsulated into standard structured information frames, ready for uploading.
[0032] S4. Wireless Communication Transmission Stage. The main control module controls the LoRa wireless communication module to transmit the collected data wirelessly over long distances to the data acquisition terminal or central control platform located in a safe area. The LoRa communication module is based on spread spectrum modulation and features low power consumption, high anti-interference, and long-distance transmission capabilities, making it suitable for environments such as tunnels and mines where traditional communication methods are difficult to cover.
[0033] S5. Module Shutdown and Return to Standby Phase. After data transmission is complete, the main control module sequentially powers off the sensors and communication modules, and the device returns to standby listening mode, with only the remote control receiver module continuing to operate. This strategy significantly reduces the overall power consumption of the system and achieves on-demand energy allocation.
[0034] Specifically, such as Figures 1 to 3 As shown in this embodiment, the remote safety monitoring device based on a remote control and low-power collaborative mechanism is suitable for remote environmental monitoring in enclosed or poorly signaled environments such as mines and tunnels. Its key innovation lies in the collaborative design of remote control trigger commands and low-power power supply control logic. Through a phased power supply strategy, it significantly reduces system energy consumption and improves the deployment flexibility and battery life of the monitoring device.
[0035] like Figure 1 As shown, the overall structure of this monitoring device mainly consists of a remote control receiver module, a power control module, a main control processing unit, a sensor module group, a LoRa communication module, and a power supply module. The remote control receiver module is constantly operational, receiving trigger signals from an external remote control. The power control module controls the power supply to each functional unit of the system according to the input commands from the remote control receiver module, supporting phased power-on and modular power-off operations. The main control processing unit (MCU) is responsible for control logic execution, data acquisition scheduling, and communication scheduling. The sensor module group includes multiple functional sensors, such as temperature and humidity, carbon monoxide / methane concentration, smoke, and tilt angle sensors. The LoRa communication module transmits the collected monitoring data to the remote receiving terminal via long-distance wireless communication. The power supply module consists of a battery and a power management IC, ensuring a stable power supply to the system.
[0036] The working process of this utility model is combined with Figure 2 The power supply control process, specifically the implementation steps are as follows:
[0037] S1: System standby monitoring phase. After deployment, the device defaults to an ultra-low power standby state, with only the remote control receiver module continuously powered. This module employs a low-power hardware design to maintain real-time monitoring under extremely low power conditions, while all other modules are powered off to extend the overall standby time.
[0038] S2: Remote Control Wake-up Phase. When the external remote control sends a wake-up signal, the remote control receiver module receives the command and outputs a trigger signal to the power control module. After responding to the command, the power control module sequentially powers on the main control MCU module, power management unit, and each sensor module according to the set power-on sequence, and then powers on the LoRa communication module in subsequent stages. The entire power supply process strictly controls the power-on duration and module startup sequence to ensure a fast and stable system response.
[0039] S3: Data Acquisition and Processing Stage. After the main control MCU module starts, it executes the built-in program to acquire real-time monitoring data from the sensor modules sequentially according to the acquisition plan. The data includes, but is not limited to, gas concentration, ambient temperature, humidity, smoke concentration, angle, and attitude. After preliminary processing (such as noise reduction, filtering, and data frame encapsulation), the acquired data is buffered and ready for transmission.
[0040] S4: Wireless Communication Transmission Phase. After the data acquisition is complete, the main control module activates the LoRa communication module. This module, based on spread spectrum communication technology, features long-distance transmission and high anti-interference performance, wirelessly transmitting formatted data to the external monitoring terminal. This communication method is particularly suitable for areas with weak GPRS / 4G signals, such as mines and tunnels.
[0041] S5: Module Power-Off and Standby Phase. After successful data transmission, the main control module sequentially powers off each functional module, leaving only the remote control receiver module in a listening power supply state. The system then returns to the standby listening phase. By implementing a short-time power supply strategy for different modules (MCU powered for approximately 50ms, sensor modules for 2-5 seconds, and LoRa modules for 3-8 seconds), overall power consumption is significantly reduced, improving the device's battery life and security.
[0042] The device structure of this utility model is as follows: Figure 4 As shown, the specific structure is as follows:
[0043] The device adopts a modular design, integrating multiple functional modules to achieve multi-parameter monitoring and remote communication control. The external casing is constructed from a metal alloy and high-strength engineering plastic composite material, boasting IP68 protection, effectively preventing dust and water damage, and possessing corrosion resistance and explosion-proof capabilities, adapting to long-term deployment requirements in complex underground environments with high coal dust and methane concentrations. A transparent window on the casing externally displays status indicator light information, facilitating quick identification of the device's status by on-site personnel. The internal structure employs a multi-layered, isolated layout, with the main control unit located centrally for unified scheduling and signal relay. To avoid electromagnetic interference affecting signal transmission and control, independent shielding compartments are installed between the power module, communication module, and electromagnetic interference sources, enhancing system stability and anti-interference capabilities. The remote control receiver module is located on the top or side of the casing to expand the signal reception coverage angle; the LoRa communication antenna uses a ceramic helical antenna or an external soft antenna structure, led out through a reserved interface in the casing, effectively improving communication distance and reliability. In terms of functional expansion, the device reserves interfaces for multiple sensor modules, supporting the monitoring of various environmental parameters such as gas, temperature, humidity, smoke, and tilt angle. All sensors adopt a standardized plug-in connection method, facilitating rapid on-site replacement, module maintenance, and functional expansion. The battery and power management circuit are encapsulated in an independent shielded compartment, effectively isolating power interference, while supporting phased power supply and deep sleep mode to meet low-power operation requirements. The device is compatible with various on-site environmental conditions, providing two standard installation structures: clamp-on and wall-mounted. Wall-mounted installation is suitable for underground walls, tunnel sidewalls, or steel structure flat areas. Standard screw holes are provided on the back of the device, allowing direct fixation to the wall or other flat structures using expansion bolts or self-tapping screws. Considering vibration interference in coal mines, rubber damping pads are added between the device and the mounting surface to effectively isolate the impact of high-frequency vibrations on the circuit structure. This installation method is suitable for long-term fixed deployment, offering high structural stability. After installation, the device fits tightly against the wall, facilitating wiring and daily inspection. Clamp-on installation is mainly suitable for cylindrical support structures, such as metal columns in tunnels or pipe supports in coal mines. The device features a pre-designed arc-shaped fixing groove on its back, which fits snugly against the surface of the cylindrical tube to form a stable support interface. A stainless steel or high-strength nylon clamp securely fastens the device to the target structure. During installation, the clamp passes through fixing holes on both sides of the device, wraps around the target column, and is tightened with screws. To prevent slippage in the vibrating downhole environment, rubber or silicone anti-slip pads are installed at the contact points between the clamp and the column, increasing friction and protecting the structural surface from scratches. This method allows for fixation without damaging infrastructure, making it particularly suitable for scenarios requiring frequent disassembly, relocation, or high deployment flexibility.
[0044] In summary, this invention employs a collaborative design of remote control commands and low-power control logic, along with a phased power supply strategy. By remotely controlling the monitoring device's switch, and utilizing the long-range, low-power, and high-reliability characteristics of LoRa communication, the device is suitable for intelligent monitoring tasks in various high-risk, enclosed, and weak signal environments. This avoids close-range manual operation, improving safety and flexibility. It enables remote control in complex and dangerous areas, preventing potential personnel injuries and ensuring stable data acquisition.
[0045] This invention fully utilizes LoRa communication technology, reducing the problems of high energy consumption and unstable communication in existing security devices, and greatly improving the usability and flexible deployment of the system.
[0046] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that, based on the technical solutions disclosed in the present utility model, all modifications or variations that can be made by those skilled in the art without creative effort should be included within the scope of protection of the present utility model.
