Description

Technical Field

[0001] The utility model relates to an integrated automatic detection and early warning device for collapse geological disasters, and belongs to the technical field of measurement sensors. Background Art

[0002] A measuring sensor is a device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules. A geological collapse monitoring device is an important tool for real-time monitoring and prevention of geological collapse disasters.

[0003] Existing automatic detection and early warning systems for landslides and geological disasters still present several challenges. Typical geological disaster monitoring sites are located outdoors, without access to utility power. Furthermore, power outages are common, preventing real-time responses or data transmission to the platform during a landslide. Furthermore, electronic equipment requires protective enclosures, poles must be fixed to the ground with concrete, and the inclinometer requires a protective casing. These factors significantly increase the difficulty of equipment installation and operation. Typical monitoring systems collect data at a high rate, such as multiple data points per second. This large amount of data is transmitted to the monitoring platform, and the data often remains largely unchanged over short periods of time, resulting in significant resource waste. Furthermore, the core sensor of the monitoring station is the inclinometer. To ensure stable operation, the monitoring station requires additional equipment, including solar panels, batteries, a solar power controller, steel poles, protective boxes, and casings. Furthermore, installation requires deep excavation and concrete anchoring. These costs can far exceed the purchase price of the inclinometer itself. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated automatic detection and early warning device for landslide geological disasters. This device features a simple structure and is easy to use. The integrated inclinometer and accelerometer is a high-precision monitoring device that integrates data acquisition, wireless communication, power supply, and self-protection functions. Combining the functions of an inclinometer and an accelerometer, it can measure an object's tilt angle, acceleration, and magnetic field orientation in real time, providing powerful support for a variety of application scenarios and addressing the issues raised in the aforementioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An integrated automatic detection and early warning device for collapse geological disasters includes a device fixing shell, a device protective shell is installed on the top of the device fixing shell, a main frame bracket is fixedly connected to the top of the device protective shell, a device body is installed inside the device protective shell, and an acrylic cover is provided on the top of the device protective shell.

[0007] Furthermore, the device protective housing is mounted on the top of the device fixed housing by means of collision screws, and the host bracket is symmetrically distributed on the top of the device protective housing. The vibration wake-up monitoring technology is based on a vibration sensor that can sense tiny vibrations or acceleration changes and convert them into electrical signals. When the device is in sleep or low-power state, the vibration sensor will continue to monitor the surrounding environment. Once a preset vibration pattern is detected or the set threshold is exceeded, the sensor will immediately trigger the circuit to wake up the device or perform a preset task. Vibration wake-up monitoring technology usually adopts a low-power design to ensure that the device is in sleep mode most of the time to save energy. The device is only woken up when a vibration is detected, thereby extending the service life of the device.

[0008] Furthermore, the device body is mounted inside the protective housing via a mainframe bracket, with the acrylic cover positioned directly above it. Its internal high-precision inclinometer measures the acceleration and rotation rate of an object in the X, Y, and Z axes, and, combined with a spatial resolution algorithm, accurately calculates the object's posture and tilt angle in three dimensions. This allows for a more comprehensive understanding of the position and posture changes of monitoring points. Changes in posture are often a precursor to changes in the position of monitoring points, thus possessing significant theoretical and practical value.

[0009] Furthermore, screws are installed inside the acrylic cover so that the acrylic cover can be installed on the top of the equipment protective shell. It has a built-in dual-mode positioning module, which uses the Beidou satellite navigation system for real-time and precise positioning, is compatible with GPS, and has Beidou + GPS dual-system positioning capabilities. Meter-level positioning ensures accurate positioning.

[0010] The beneficial effects of the utility model are:

[0011] (1) The present invention provides an equipment body, which is integrated into one unit, thereby eliminating auxiliary equipment such as foundation, steel poles, and equipment boxes. This reduces the difficulty of equipment installation and greatly reduces procurement and installation costs, thereby improving the efficiency of capital use. By installing the equipment body inside the equipment protective shell, and then stably installing it inside the equipment protective shell through an acrylic cover, all equipment is integrated together through the equipment protective shell, making equipment protection simpler. It only requires purchasing materials with high hardness and ensuring waterproof and dustproof properties to provide equal protection for all equipment, circuits, etc., and is suitable for long-term use in the wild.

[0012] (2) The present invention adopts a low-power design concept by setting up a device body. The MCU enters a sleep state at a fixed time and shuts down surrounding electronic components at the same time. In view of the characteristics of long-term field monitoring, after the MCU wakes up at a fixed time, it first performs a data sorting after data collection is completed to determine the amount of data change. For small changes or no changes, the number of uploads to the monitoring platform is reduced, reducing the amount of data, not only greatly reducing energy consumption but also improving data utilization efficiency. The monitor has a built-in vibration sensor, which immediately wakes up the MCU to collect and analyze data and transmit it to the platform. When the number of vibrations reaches a certain value, such as more than 5 vibrations in 1 minute, it is considered that there may be human damage, and an alarm message is sent to the platform. The inspection personnel will conduct on-site inspections of the equipment status and deal with any problems in a timely manner. In the event of theft, the device can be tracked based on real-time positioning information. Unlike general device integration, the integrated remote sensing micro-power consumption surface tilt monitor proposed by the present invention has only one MCU, which comprehensively manages sensor data collection, storage, and data transmission; comprehensively manages power supply management and energy replenishment; enters a sleep state at a fixed time, and wakes up by itself or externally (when a large vibration or angle change occurs). In traditional monitoring stations, different functional devices have separate MCUs, each performing its own function, resulting in low overall efficiency. For example, the tilt sensor has its own MCU, the data acquisition and transmission equipment has its own MCU, and the solar power controller has its own MCU. It is extremely difficult to coordinate these MCUs to achieve low power consumption, which not only increases economic costs but also reduces operational efficiency.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0022] An integrated automatic detection and early warning device for collapse geological disasters includes a device fixed shell 1, a device protective shell 2 is installed on the top of the device fixed shell 1, a main frame bracket 3 is fixedly connected to the top of the device protective shell 2, a device body 4 is installed inside the device protective shell 2, and an acrylic cover 5 is provided on the top of the device protective shell 2.

[0023] Specifically, such as Figure 1 As shown, the device protective shell 2 is installed on the top of the device fixed shell 1 through collision screws, the host bracket 3 is symmetrically distributed on the top of the device protective shell 2, the device body 4 is installed inside the device protective shell 2 through the host bracket 3, and the acrylic cover 5 is located directly above the device body 4. Screws are installed inside the acrylic cover 5 to install the acrylic cover 5 on the top of the device protective shell 2.

[0024] Specifically, wake-on-vibration monitoring technology is based on a motion sensor that detects minute vibrations or acceleration changes and converts them into electrical signals. When the device is in sleep or low-power mode, the sensor continuously monitors its surroundings. Upon detecting a preset vibration pattern or exceeding a set threshold, the sensor immediately triggers circuitry to wake the device or execute a pre-set task. Wake-on-vibration monitoring technology typically employs a low-power design, ensuring the device remains in sleep mode most of the time to conserve energy. It wakes the device only when vibration is detected, extending its lifespan. Its internal high-precision inclinometer measures the acceleration and rotation rate of an object in the X, Y, and Z axes. Combined with spatial resolution algorithms, it accurately calculates the object's posture and tilt angle in three dimensions. This allows for a more comprehensive understanding of the location and posture changes of monitoring points. Attitude changes are often a precursor to changes in the monitoring point's position, which holds significant theoretical and practical value. The built-in dual-mode positioning module utilizes the Beidou satellite navigation system for real-time, precise positioning, compatible with GPS, and capable of dual-system positioning with Beidou and GPS, ensuring meter-level positioning accuracy.

[0025] In this embodiment, a sleep mechanism is used to reduce energy consumption while improving data utilization efficiency. Since geological disaster displacement monitoring is long-term, the trend of geological collapse changes slowly, or in other words, the displacement change amount is basically unchanged on a specific day, so the data acquisition frequency does not need to be very high. Within a day, the MCU is basically in a sleep state, and the surrounding circuits are basically in a power-off state when the MCU is in sleep mode, saving a lot of electricity. Within a day, the MCU automatically wakes up several times at regular intervals to collect data such as angles, azimuths, and positioning positions, and compares and analyzes data changes. When the data does not change, the data is transmitted to the remote platform once or several times a day. Only when the monitored data changes significantly, the frequency of uploading data is automatically increased, and a warning signal of 0 or 1 is issued. The power supply system is highly integrated. Since the sleep mechanism is enabled, integrated power supply becomes possible. The integrated inclinometer proposed in the present invention mainly uses multiple groups of lithium batteries to form a storage battery, and a maximum battery pack of 36000mA can be configured as needed. In order to meet the requirements of large data transfer and long-term use, an external solar panel is integrated. Through the solar charge and discharge control circuit integrated in the circuit board, the monitor can be replenished with power during daily use, so that the monitor can be used indefinitely in theory. The integrated bracket is easy to install.

[0026] The integrated inclinometer accelerometer proposed in the present invention is an integral device in appearance, with a device fixing shell 1 provided at the bottom, which can be conveniently fixed and installed at the monitoring point. The device can work normally as soon as it is powered on, and no other auxiliary infrastructure work is required, which greatly reduces the installation difficulty and installation cost.

[0027] The built-in vibration and positioning module provides certain anti-theft, anti-vandalism, and location tracking capabilities. The vibration sensor collects vibration frequency and count. When vibration occurs, it not only wakes up the MCU but also activates the positioning module when the vibration count reaches a certain threshold, sending an alarm signal to the platform. This reminds inspection personnel to promptly check the device status and track the device based on the positioning information.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
