Description

Technical Field

[0001] The present invention relates to the field of monitoring technology, and in particular to an Internet of Things intelligent stone monitoring system. Background Art

[0002] Deformation geological phenomena usually pose serious hazards, such as changing river courses, forming barrier lakes, and endangering human life and property safety.

[0003] In order to reduce the hazards caused by deformation geological phenomena, river embankment projects, roads, bridges, mountains, and buildings are usually monitored so that early warning of deformation geological phenomena can be given, thereby reducing the hazards by taking appropriate measures as soon as possible.

[0004] At present, there are three main ways to monitor and warn of deformation geological phenomena:

[0005] Method 1: Pressure monitoring and warning technology; that is, a pressure sensor is set below the location where deformation is likely to occur, and the pressure signal collected by the pressure sensor is judged (such as whether the pressure exceeds a threshold, etc.) to determine whether a deformation geological phenomenon has occurred, thereby realizing an alarm for deformation geological phenomena.

[0006] Method 2: Monitoring and warning technology based on video images; that is, using video equipment to shoot locations prone to deformation, and determining whether deformation geological phenomena have occurred by analyzing and identifying the images captured by the video equipment, thereby realizing an alarm for deformation geological phenomena.

[0007] Method three: monitoring and warning technology based on contact displacement measurement; that is, a displacement sensor is set at a location where deformation geological phenomena are prone to occur, and a baffle is set at the moving end where deformation may occur. The displacement sensor and the baffle are in contact with each other. The displacement sensor can measure the displacement of the moving end (such as the collapsed body) according to the deformation of the elastic element inside the baffle. By judging the displacement, it is determined whether a mountain deformation geological phenomenon has occurred, thereby realizing an alarm for deformation geological phenomena.

[0008] However, it was found during the implementation of the present invention that:

[0009] While the first method described above can monitor deformational geological phenomena at a low cost, since pressure sensors typically only measure vertical pressure changes, they often miss detections in situations such as displacement. Furthermore, since the pressure sensor must be located below the monitoring location, field installation often presents significant challenges, especially when the pressure sensor is suspended high above a location prone to collapse.

[0010] In the second method described above, the video equipment typically consumes a lot of power, making it difficult to power it for extended periods in the field. Furthermore, because moving objects in real-world environments can interfere with image analysis, this method often misidentifies moving non-collapsed objects as collapsing objects, or vice versa, compromising the accuracy of the alarm. Furthermore, while this method can provide alarms for deformational geological phenomena, it lacks the ability to provide early warning of mountain deformational geological phenomena.

[0011] In the third method mentioned above, when installing the displacement sensor and the baffle, it is necessary to constantly adjust the contact force between the displacement sensor and the baffle, which makes the installation difficult. In addition, this method has a high implementation cost due to its high requirements on the material of the components. For example, the elastic coefficient of the elastic element inside the displacement sensor should remain unchanged for a long time under pressure. For example, the baffle should not be deformed due to insufficient rigidity, nor should it be easily broken due to excessive rigidity. In addition, since the outdoor environment is more likely to cause the displacement sensor (such as the internal elastic element) and the contact baffle to age and corrode, this method often has the problem of insufficient displacement measurement accuracy, which in turn has a negative impact on the accuracy of the warning of deformation geological phenomena. Summary of the Invention

[0012] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide an Internet of Things intelligent stone monitoring system.

[0013] The present invention is achieved through the following technical solutions:

[0014] An Internet of Things (IoT) smart stone monitoring system, comprising a smart stone and an IoT gateway. The smart stone comprises a housing, a battery, a transmitter chip, and a triaxial acceleration sensor. The housing is in the shape of a stone and is made of rubber. The battery, transmitter chip, and triaxial acceleration sensor are encapsulated in the housing using a glue potting process.

[0015] The Internet of Things gateway is used to receive the wireless signal transmitted by the smart stone.

[0016] In order to further realize the present invention, the following technical solutions may be preferably used:

[0017] Preferably, the monitoring system also includes a data center, which is used for data analysis, data storage, data aggregation, threshold setting, rule engine and visual display of wireless signals received by the material gateway.

[0018] Preferably, the monitoring system further comprises a platform early warning component, and the platform early warning component is used for sending message notifications, SMS notifications, email notifications and device linkage to the data center data.

[0019] Preferably, there are multiple smart stones in the monitoring system, and the multiple smart stones are divided into several groups. Each group of smart stones is arranged in a U-shaped series through hinged fasteners, and the smart stones at both ends of each group are connected to the Internet of Things gateway by signal.

[0020] Through the above technical solution, the beneficial effects of the present invention are:

[0021] The core working mechanism of the smart stone of the present invention relies on a set of high-precision gyroscopes and accelerometer arrays. These sensors can fully capture the deformation situation by accurately calculating the inclination of each section relative to the direction of gravity.

[0022] In practical applications, whether facing vertically, horizontally, or anywhere in between, it accurately aligns with the intended displacement direction, ensuring measurement effectiveness. The intelligent stone array continuously reports the posture data of each node to the data center (on a configurable interval, in seconds). The data center deploys a hazard warning system software service. The system calculates the displacement direction, angle, and amount based on the changes in multiple sets of posture data.

[0023] The monitoring system of the present invention can freely configure the tilt and displacement warning thresholds. When the posture change value calculated by the system reaches the set threshold, the system triggers the event mechanism. The event can be set as a message notification, email notification, or other hardware device protocol communication form to perform forecast warning and scene linkage.

[0029] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Example 1:

[0032] An Internet of Things (IoT) smart stone monitoring system, comprising a smart stone and an IoT gateway. The smart stone comprises a housing, a battery, a transmitter chip, and a triaxial acceleration sensor. The housing is in the shape of a stone and is made of rubber. The battery, transmitter chip, and triaxial acceleration sensor are encapsulated in the housing using a glue potting process.

[0033] The Internet of Things gateway is used to receive the wireless signal transmitted by the smart stone.

[0034] Smart stones come in two types: internal and external sensors. The internal sensor integrates a triaxial accelerometer on the transmitter PCB. The external sensor has four-core wires extending from the PCB to the probe board, which also integrates a triaxial accelerometer.

[0035] The IoT gateway integrates an ESP8266 MCU chip, an ASK315Mhz signal receiving module, a W5100s Ethernet chip, and a 12V power adapter circuit.

[0036] The monitoring system also includes a data center, which is used for data analysis, data storage, data aggregation, threshold setting, rule engine and visualization display of wireless signals received by the material gateway.

[0037] The monitoring system further comprises a platform early warning component, which is used for sending message notifications, SMS notifications, email notifications and device linkage notifications to the data center data.

[0038] There are multiple smart stones in the monitoring system, and the multiple smart stones are divided into several groups. Each group of smart stones is arranged in a U-shaped series through hinged fasteners, and the signals of the smart stones at both ends of each group are connected to the Internet of Things gateway.

[0039] The array-type intelligent stones are linked end to end and arranged in a U-shaped series form, which can be expanded to surface monitoring. The U-shaped two-way communication function allows the number to be expanded at will, and when any node fails, the monitoring data can still be transmitted normally.

[0040] Array sensors are arranged in a U-shaped array, and multi-sensor collaborative monitoring can improve monitoring accuracy and help to detect potential structural problems in a timely manner.

[0041] By deploying multiple sensing units at different locations, array sensors can achieve comprehensive monitoring of a large area.

[0042] Even if some sensing units fail, other units can continue to work, providing redundant data and improving system reliability.

[0043] Combined with data processing algorithms, array sensors can realize automated monitoring and intelligent analysis; collaborative analysis of multi-sensor data enables it to cover the deformation analysis and monitoring range of points, lines, and surfaces.

[0044] The smart stone and the main control board use 315Mhz wireless signal data transmission. To prevent signal interference from causing data confusion, the signal binary code uses check bits to ensure correct data.

[0045] Verification method: The smart stone sends 7 bytes of data each time. Figure 4 As shown, it includes ID x, y, x-tilt angle and status code.

[0046] Due to the limitation of 8-bit binary, in order to express 360°, the following bytes are split into 10 bits to represent a value.

[0047] The last bit of each byte is used as a check bit (the ID is not included in the check). If the number of 1s in the byte is odd, the last bit is 1; if the number of 1s is odd, the last bit is 0. The check bit is not used in numerical calculations and is only used for verification.

[0048] The following is the real data:

[0049] BYEET0 BYEET1 BYEET2 BYEET3 BYEET4 BYEET5 BYEET6 00100111 00000010 00100001 10101100 01100011 00001010 00111111

[0050] The first and second bits are the unique ID of the transmitter board. The ID is composed of the second binary bit as the high bit and the first bit as the low bit. ID = 00000010 00100111 is parsed as 551 in decimal.

[0051] Xy inclination angle: The first 6 digits of BYTE2 + the first 2 digits of BYTE3 are 0010000110, minus the check digit 001000010. The decimal result is 66.

[0052] YZ inclination angle: The decimal result of digits 2 to 5 of BYTE3 plus the first 4 digits of BYTE4 (1011000110) minus the check digit is 358.

[0053] XZ inclination angle: The decimal result of the last 4 digits of BYTE4 + the first 6 digits of BYTE5 (0011000010) minus the check digit (001000010) is 66.

[0054] Status: The last 2 digits of BYTE5 + the first 7 digits of BYTE6 are 100011111, minus the check digit: 10011111. Each digit of the status represents a different parameter:

[0055] state 1 0 0 normal Power shortage 1 Inclination angle greater than 45° 2 Inclination angle greater than 90° 3 There is continuous vibration exceeding 10° 4 There is continuous vibration exceeding 30° 5 Not used yet 6 underwater sensors Water sensor 7 Disconnection

[0056] The main control board is responsible for receiving data and parsing and verifying it. It is bound to the transmitter board's unique ID to prevent signal transmission confusion.

[0057] The main control board program process is as follows Figure 5 shown.

[0058] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
