Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention are within the scope of the present invention.
The collapse refers to sudden and sharp falling movement of rock mass and soil mass on a steep hill under the action of gravity. Most of the time, the method is carried out on a slope of more than 60-70 degrees. The collapsed material is called a collapsed body. The separation interface between the collapsed body and the sloping body is called a collapsed surface, and the collapsed surface is often an interface with a large inclination angle. When the collapse occurs, the inclination angle of the collapse surface tends to change greatly. Accordingly, monitoring of a geological collapse surface generally refers to monitoring the inclination of the geological collapse surface.
In order to improve the safety of monitoring a geological collapse surface, the embodiment of the invention provides collapse mesh monitoring equipment, a method and a system. First, an exemplary description is given of a mesh collapse monitoring system provided in an embodiment of the present invention:
in the embodiment of the present invention, the system may include: the monitoring system comprises a plurality of sensors and a collapsed mesh monitoring terminal; the sensors are in communication connection with the collapsed mesh monitoring terminal; the plurality of sensors covers the collapse surface.
As shown in fig. 1, the collapsed mesh monitoring terminal may include: a control module 110, a historical data storage module 120 and a communication transmission module 130; the control module 110 may include: an acquisition control unit 111 and a data processing unit 112;
the acquisition control unit 111 is configured to send a data acquisition command to a plurality of sensors arranged on a geological collapse surface according to a preset data acquisition frequency; acquiring each original inclination angle data acquired by each sensor;
the data processing unit 112 is configured to calculate, for each sensor, an accumulated change amount of the tilt angle data, an incremental change amount of the tilt angle data, and a change rate of the tilt angle data in a preset time period at a position where the sensor is located based on the original tilt angle data and historical tilt angle data, which is stored in the historical data storage module 120 and acquired by the sensor, in the preset time period;
the communication transmission module 130 is configured to upload the original tilt angle data, the cumulative variation of the tilt angle data, the incremental variation of the tilt angle data, and the change rate of the tilt angle data to a software platform.
According to the mesh collapse monitoring system provided by the embodiment of the invention, a data acquisition command is sent to a plurality of sensors arranged on a collapse surface according to a preset data acquisition frequency; acquiring each original inclination angle data acquired by each sensor; for each sensor, calculating the accumulated variation of the inclination data, the incremental variation of the inclination data and the variation rate of the inclination data within a preset time period of the position of the sensor based on the original inclination data and the stored historical inclination data within the preset time period acquired by the sensor; and uploading the original inclination angle data, the accumulated variation of the inclination angle data, the incremental variation of the inclination angle data and the variation rate of the inclination angle data to a software platform. By applying the embodiment of the invention, the sensors are controlled to collect the original inclination data according to the preset data collection frequency, the basic operation is carried out on the original inclination data, and the original inclination data and the operation result are uploaded to the software platform, so that the automatic collection and report of the inclination data of the geological collapse surface are realized, relevant personnel can monitor the inclination data of all parts of the geological collapse surface through the software platform, manual field measurement is not needed, and the efficiency and the working safety of monitoring the relevant parameters of the geological collapse surface are improved. Meanwhile, original inclination angle data are collected through a plurality of sensors arranged on the collapse surface, and the plurality of sensors cover the collapse surface, so that the integrity of the geological collapse surface is monitored.
In the embodiment of the present invention, the acquisition control unit may send a data acquisition command to each sensor according to a preset data acquisition frequency. For example, data acquisition commands may be sent to each sensor every 1 hour, 24 hours, 72 hours, etc. to acquire raw inclination data acquired by a plurality of sensors disposed on a geological collapse surface.
The sensor arranged on the geological collapse surface is used for measuring an inclination angle and can acquire the inclination angle data of the position. The sensor may be a tilt sensor, such as a dual-axis tilt sensor, or a three-axis tilt sensor. The sensor may be a two-axis acceleration sensor, a three-axis acceleration sensor, or the like. The coordinate axes of the dual-axis inclination angle (acceleration) sensor include two mutually perpendicular directions, the coordinate axes of the three-axis inclination angle (acceleration) sensor include three coordinate axes x, y and z, two of the three coordinate axes are mutually perpendicular, the specific directions can be preset according to actual needs, and the invention is not particularly limited to this. In the embodiment of the invention, the type of the sensor can be selected according to actual measurement requirements. In an embodiment of the invention, a triaxial acceleration sensor can be selected to measure the inclination angle of each position of the geological collapse surface.
The tilt angle may generally refer to an angle formed by a straight line or plane and a horizontal line or plane, or an angle formed by a straight line and its projection on a plane, or the like. In an embodiment of the present invention, the raw tilt data may include different data according to different types of sensors. Taking the three-axis acceleration sensor as an example, the raw tilt angle data collected by the sensor may include: the angle between the x, y, z axes of the sensor and the horizontal (denoted x, y, z), the angle between the plane formed by the xy axes of the sensor and the horizontal, and the angle Az1 between the projection of the x axis of the sensor on the horizontal and the magnetic north (the direction in which the magnetic needle points to the north pole of earth magnetism).
In the embodiment of the invention, the sensors can be installed according to a mesh structure according to the requirement of on-site geological monitoring. As a specific implementation mode, a plurality of sensors can be uniformly arranged on the geological collapse surface according to the length and the width of the geological collapse surface. The installation position of the sensor can be determined according to the geology of the geological collapse surface. For example, sensors may be densely installed in a geologically unstable hazardous area and sparsely installed in a geologically stable, relatively safe area. Of course, the sensors can be installed according to the length and width of the geological collapse surface and the geology, for example, the sensors can be densely installed in a dangerous area with unstable geology, and the sensors can be uniformly installed in the rest areas.
The sensors CAN be connected through a CAN bus to form a mesh structure, namely, each sensor is connected with each sensor adjacent to the sensor through the CAN bus. As shown in fig. 2 a. In fig. 2a, the thicker nodes represent sensors, and the connection lines between the nodes are CAN buses.
The CAN bus is a serial communication protocol according to ISO (International Organization for Standardization) International Standardization. A communication network capable of effective distributed control or real-time control adopts a lossless structure bit-by-bit arbitration direction to compete for issuing data to a bus, which abolishes station-to-station coding and instead codes communication data, so that different contacts can receive the same data at the same time. The CAN bus data communication has outstanding reliability, real-time performance and flexibility, and ensures the data transmission safety of each sensor on the geological collapse surface.
In the embodiment of the invention, the collapse mesh-shaped monitoring terminal is arranged near a geological collapse surface. After receiving the data acquisition instruction, the sensors CAN acquire the inclination angle data of the positions where the sensors are located, and the acquired original inclination angle data CAN be transmitted to the preset main sensor through the CAN bus. The main sensor can be preset according to actual needs. For example, a sensor closest to the above-described collapsed mesh monitoring terminal may be set as the main sensor. The main sensor may be connected to the collapsing mesh monitoring terminal through a CAN bus, and upload the original tilt data acquired by each sensor to the acquisition control unit 111 of the collapsing mesh monitoring terminal. The raw tilt data uploaded to the acquisition control unit 111 by each sensor includes the identifier of each sensor. The sensor identifier may be a sensor number, or may be a position coordinate where the sensor is located.
In one embodiment of the present invention, each sensor may be connected to each sensor adjacent to the sensor to form a mesh structure. Of course, each sensor may not be connected to all adjacent sensors, as long as each sensor can transmit the collected data to the preset main sensor along the mesh structure.
In the embodiment of the present invention, as shown in fig. 2b, fig. 2b is a schematic structural diagram of a monitoring system for monitoring a collapse network according to the embodiment of the present invention. The sensors are in communication connection with the collapsed mesh monitoring terminal; the sensors are connected by a CAN bus to form a sensor array to cover the collapse surface.
After receiving the raw tilt data uploaded by each sensor, the acquisition control unit 111 may send each raw tilt data to the data processing unit 112 for further processing.
The data processing unit 112 may calculate, for each sensor, an accumulated change amount of the tilt angle data, an incremental change amount of the tilt angle data, and a change rate of the tilt angle data in a preset time period at a position of the sensor based on the original tilt angle data and historical tilt angle data in the preset time period, which is stored in the historical data storage module and acquired by the sensor.
As described above, the raw tilt data may include a variety of tilt data. The historical data storage module can correspondingly store the original inclination angle data acquired in a preset time period and the sensor identification. The preset time period can be preset according to actual needs, such as the last month, the last half month, and the like.
The accumulated variation of the inclination angle data may be a difference between the original inclination angle data collected by the sensor at this time and the first historical inclination angle data collected by the sensor and stored in the historical data storage module. The inclination angle data increment variation is a difference value between the original inclination angle data acquired by the sensor at this time and the previous historical inclination angle data acquired by the sensor and stored in the historical data storage module. The change rate of the inclination data may be obtained using the above-described accumulated change amount of the inclination data/a preset time period.
The communication transmission module 130 may upload the original tilt angle data, the accumulated variation of the tilt angle data, the incremental variation of the tilt angle data, and the change rate of the tilt angle data to the software platform according to a preset data reporting frequency. Each data uploaded to the software platform by the communication transmission module comprises a sensor identifier corresponding to the data. The data reporting frequency can be set in advance according to actual monitoring requirements, and can be the same as or different from the data acquisition frequency. For example, the acquisition and reporting may be performed once in 24 hours, once in 1 hour, or once in 12 hours, once in 24 hours, and the like, which is not specifically limited in the present invention.
In the embodiment of the invention, the original inclination angle data collected by each sensor can be stored in the historical data storage module after being received every time, so that the data is ensured not to be lost. If the data is collected but cannot be reported to the software platform temporarily, the collection control unit 111 may control each sensor to collect the original tilt angle data according to the preset data collection frequency all the time, and store each collected original tilt angle data and the sensor identifier in the historical data storage module correspondingly. When the collapsed mesh monitoring terminal can report data to the software platform, the historical data storage module can report each stored data through the communication transmission module.
In the embodiment of the present invention, the communication transmission module may upload the data to the software platform through a third party network, or may upload the data to the software platform through a wireless ad hoc network. The wireless ad hoc network is a portable communication mode, can quickly establish a set of decentralized network environment in the environment without any network, and does not depend on conventional infrastructures such as a machine room network and the like. Under the condition of visual or non-visual range, the ad hoc network system can simply carry out networking and transmit the voice, video and data of the front end.
As a specific implementation manner, the communication transmission module may include a wireless communication transmission sub-module and an ad hoc network communication transmission sub-module. The wireless communication transmission sub-module can report the data to the software platform through a third-party network in a 4G/5G, NB-lot (Narrow Band Internet of Things, narrowband cellular Internet of Things), Beidou short messages and other modes. The ad hoc network communication transmission sub-module may broadcast each data through LORA (Long Range Radio) without network signals.
Of course, the above-mentioned collapse mesh monitoring terminal may further include a communication interface, such as an RS232 interface, an RS485 interface, and the like. The communication transmission module can report the data to the software platform in a wired mode through the communication interface.
When a geological collapse surface deforms, five parameters of x, y, z, angle and Az1 are collected, the five parameters are simultaneously gathered to the collapse mesh monitoring terminal, the collapse mesh monitoring terminal transmits data to the software platform through 4G/5G, LORA, NB-lot and Beidou short messages, or transmits the data to the software platform through an RS485 interface and an RS232 interface through wires, relevant personnel do not need to measure on site, the working strength is reduced, and meanwhile, danger is avoided. Meanwhile, the plurality of sensors are installed on the geological collapse surface according to the mesh structure, and the sensors are communicated through the CAN bus to cover the geological collapse surface, so that the integral monitoring of the geological collapse surface CAN be realized.
In addition, the data are all calculated locally and then result data are uploaded to a software platform, and the calculation and analysis of the data are carried out locally, so that the increase of communication cost in data return is reduced.
In an embodiment of the present invention, the data processing unit 112 is further configured to establish a collapse surface inclination data change model based on the original inclination data acquired by each sensor;
the communication transmission module 130 is further configured to upload the collapse surface inclination angle data change model to the software platform.
In the embodiment of the present invention, during the process of installing the sensors and the collapsed mesh monitoring terminal, the position information, the coordinate displacement and the elevation data of the sensors may be configured to the collapsed mesh monitoring terminal. The position information of the sensor may be longitude and latitude information of a position where the sensor is located. The coordinate displacement of each sensor may refer to a coordinate displacement of a position of the sensor relative to a position of the collapsed mesh monitoring terminal.
After the monitoring network is installed, the collapsed mesh monitoring terminal can control each sensor to collect original inclination angle data in real time, and the original inclination angle data collected by each sensor is initialized to zero by combining position information, coordinate displacement and elevation data of each sensor, so that the original inclination angle data collected initially are represented on the same plane, and a monitoring network is formed. The monitoring network can display the raw inclination angle data collected by the sensors in a point mode.
After the collapse mesh-shaped monitoring terminal acquires the original inclination angle data acquired by each sensor each time, a collapse surface inclination angle data change model can be generated based on the monitoring network. The change condition of the original inclination angle data acquired by each sensor relative to the initial monitoring net can be displayed in the model. For each sensor, if the original inclination angle data of the position of a certain sensor is deformed, in the collapse surface inclination angle data change model, the point corresponding to the sensor is raised or recessed compared with the initial monitoring network.
