Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by the person skilled in the art based on the present invention are included in the scope of protection of the present invention.
Collapse refers to sudden and rapid falling movement of rock mass and soil mass on a steep hillside under the action of gravity. Most occur on slopes greater than 60 deg. to 70 deg.. The collapsed material is called a collapsed body. The separation interface of the collapsed body and the slope body is called as a collapsed surface, and the collapsed surface is often the interface with a large inclination angle. When collapse occurs, the inclination angle of the collapsed surface tends to vary greatly. Thus, monitoring of a geologic collapsed surface generally refers to monitoring the dip angle of the geologic collapsed surface.
In order to improve the safety of monitoring a geological collapse surface, the embodiment of the invention provides collapse net-shaped monitoring equipment, method and system. The following first illustrates a collapsed mesh monitoring system provided by an embodiment of the present invention:
in an embodiment of the present invention, the system may include: a plurality of sensors and a collapsed mesh monitoring terminal; the plurality of sensors are in communication connection with the collapsed mesh monitoring terminal; the plurality of sensors covers the collapsed face.
As shown in fig. 1, the collapsed mesh monitoring terminal may include: a control module 110, a history 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 data acquisition commands to a plurality of sensors disposed on the 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 of the sensors, an accumulated change amount of tilt angle data, an incremental change amount of tilt angle data, and a change rate of tilt angle data in a preset time period of a position of the sensor, based on the raw tilt angle data and the historical tilt angle data in the preset time period acquired by the sensor and stored in the historical data storage module 120;
The communication transmission module 130 is configured to upload each of the raw tilt data, each of the cumulative change of tilt data, the incremental change of tilt data, and the change rate of tilt data to a software platform.
According to the collapse net-shaped monitoring system provided by the embodiment of the invention, data acquisition commands are sent to a plurality of sensors arranged on a collapse surface according to preset data acquisition frequency; acquiring each original inclination angle data acquired by each sensor; for each sensor, calculating the cumulative change amount of the inclination angle data, the incremental change amount of the inclination angle data and the change rate of the inclination angle data in the preset time period of the position of the sensor based on the original inclination angle data and the stored historical inclination angle data in the preset time period acquired by the sensor; uploading the original tilt angle data, the cumulative change amount of the tilt angle data, the incremental change amount of the tilt angle data and the change rate of the tilt angle data to a software platform. By adopting the embodiment of the invention, the sensors are controlled to acquire the original inclination angle data according to the preset data acquisition frequency, the original inclination angle data is subjected to basic operation, and the original inclination angle data and the operation result are uploaded to the software platform, so that the automatic acquisition and reporting of the inclination angle data of the geological collapse surface are realized, related personnel can monitor the inclination angle data of each place 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 related parameters of the geological collapse surface are improved. Meanwhile, raw dip angle data are acquired through a plurality of sensors arranged on the collapsed surface, and the collapsed surface is covered by the plurality of sensors, so that the integrity of the geological collapsed surface is monitored.
In the embodiment of the invention, the acquisition control unit can send the data acquisition command to each sensor according to the preset data acquisition frequency. For example, data acquisition commands may be sent to each sensor at 1 hour, 24 hours, 72 hours, etc. intervals to acquire raw dip data acquired by a plurality of sensors disposed on a geologic collapse surface.
The sensor arranged on the geological collapse surface is a sensor for measuring the dip angle, and dip angle data of the position can be collected. The sensor may be an inclination sensor, for example, a biaxial inclination sensor, a triaxial inclination sensor, or the like. The sensor may be a biaxial acceleration sensor, a triaxial acceleration sensor, or the like. The coordinate axes of the biaxial inclination angle (acceleration) sensor comprise two mutually perpendicular directions, the coordinate axes of the triaxial inclination angle (acceleration) sensor comprise three coordinate axes x, y and z, 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 the directions. In the embodiment of the invention, the type of the sensor can be selected according to actual measurement requirements. In one embodiment of the invention, three-axis acceleration sensors may be selected to measure the dip angle at each location of the geologic collapse.
The inclination angle may generally refer to an angle formed by a straight line or a plane and a horizontal line or a horizontal plane, or an angle formed by a straight line and a projection of the straight line on the plane, etc. In the embodiment of the present invention, the raw tilt angle data may include different data according to different sensor types. Taking the triaxial acceleration sensor as an example, the raw tilt angle data collected by the sensor may include: the angles between the x, y and z axes of the sensor and the horizontal plane (expressed as x, y and z), the angle between the plane formed by the xy axis of the sensor and the horizontal plane, and the angle Az1 between the projection of the x axis of the sensor on the horizontal plane and the magnetic north (the direction of the magnetic needle pointing to the geomagnetic north).
In the embodiment of the invention, the plurality of sensors can be installed according to a network structure according to the requirement of on-site geological monitoring. As a specific embodiment, a plurality of sensors may be uniformly mounted on the geological collapse surface according to the length and width of the geological collapse surface. The mounting location of the sensor may also be determined in accordance with the geology of the geologic collapse surface. For example, sensors may be densely installed in geologically unstable hazardous areas and sparsely installed in geologically stable relatively safe areas. Of course, the sensors may be installed according to the length and width of the geological collapse surface and geology, for example, the sensors may be densely installed in a dangerous area where geology is unstable, and the sensors may be uniformly installed in the remaining area.
The sensors CAN be connected through a CAN bus to form a net structure, namely, each sensor is connected with each adjacent sensor through the CAN bus. As shown in fig. 2 a. In fig. 2a, the thicker nodes represent the sensor, and the connection lines between the nodes are CAN buses.
The CAN bus is a serial communication protocol internationally standardized according to ISO (International Organization for Standardization ). The communication network can be effectively controlled in a distributed mode or in real time, the data is distributed to the bus in a competition mode in a bit-by-bit arbitration direction of a lossless structure, the station-to-bit encoding is omitted, the communication data is encoded instead, and different joints can receive the same data at the same time. The CAN bus data communication has outstanding reliability, instantaneity and flexibility, and ensures the data transmission safety of each sensor on the geological collapse surface.
In the embodiment of the invention, the collapse net-shaped monitoring terminal is arranged near a geological collapse surface. After each sensor receives the data acquisition instruction, the inclination angle data of the position of each sensor CAN be acquired, and the acquired original inclination angle data CAN be transmitted to a preset main sensor through the CAN bus. The main sensor can be preset according to actual needs. For example, the 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 collapsed mesh monitoring terminal through a CAN bus, and upload raw tilt angle data collected by each sensor to the collection control unit 111 of the collapsed mesh monitoring terminal. The raw tilt data uploaded to the acquisition control unit 111 by each sensor includes the identification of each sensor. The sensor identifier may be a sensor number, or a position coordinate where the sensor is located, etc.
In one embodiment of the present invention, each sensor may be connected to each sensor adjacent thereto to form a mesh structure. Of course, each sensor may not be connected to all the adjacent sensors, so long as each sensor can transmit the acquired data to the preset main sensor along the network structure.
In the embodiment of the present invention, as shown in fig. 2b, fig. 2b is a schematic structural diagram of a collapsed mesh monitoring system according to the embodiment of the present invention. The plurality of sensors are in communication connection with the collapsed mesh monitoring terminal; the sensors are connected by a CAN bus to form a sensor array, and the sensor array covers the collapsed surface.
After the acquisition control unit 111 receives the raw tilt data uploaded by each sensor, each raw tilt data may be sent to the data processing unit 112 for further processing.
The data processing unit 112 may calculate, for each of the sensors, a cumulative 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 of the sensor location, based on the raw tilt angle data and the historical tilt angle data in the preset time period acquired by the sensor and stored in the historical data storage module.
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 may be preset according to actual needs, for example, in the last month, in the last half month, and so on.
The cumulative change of the inclination angle data can be the difference value between the original inclination angle data acquired by the sensor and the first historical inclination angle data acquired by the sensor and stored in the historical data storage module. The incremental change of the inclination angle data is the difference value between the original inclination angle data acquired by the sensor at the time and the last historical inclination angle data acquired by the sensor and stored in the historical data storage module. The inclination data change rate can be obtained using the above-described inclination data cumulative change amount/preset period of time.
The communication transmission module 130 may upload each original tilt angle data, each cumulative change amount of the tilt angle data, each incremental change amount of the tilt angle data, and each change rate of the tilt angle data to the software platform according to a preset data reporting frequency. And the communication transmission module uploads each data to the software platform, wherein each data 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 the data acquisition frequency or different from the data acquisition frequency. For example, 24-hour collection and reporting may be set once, 1-hour collection and reporting may be set once, 12-hour collection may be set once, 24-hour reporting may be set once, etc., which is not particularly limited in the present invention.
In the embodiment of the invention, the original inclination angle data acquired by each sensor can be stored in the historical data storage module after being received each time, so that the data is ensured not to be lost. If the data is collected but cannot be reported to the software platform, the collection control unit 111 can control each sensor to collect the original inclination angle data all the time according to the preset data collection frequency, and store each collected original inclination angle data and the sensor identification in the history data storage module correspondingly. When the collapse mesh monitoring terminal can report data to the software platform, the historical data storage module can report all stored data through the communication transmission module.
In the embodiment of the invention, the communication transmission module can upload the data to the software platform through a third party network, and can upload the data to the software platform through a wireless ad hoc network. The wireless ad hoc network is a portable communication mode, and can quickly construct a set of non-centralized network environment without any network environment, and the wireless ad hoc network does not depend on conventional infrastructure such as a conventional machine room network. The ad hoc network system can simply carry out networking under the condition of visual or non-visual distance, and transmits voice, video and data at 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 submodule can report the data to the software platform through a third party network in a mode of 4G/5G, NB-lot (Narrow Band Internet of Things, narrowband cellular Internet of things), beidou short messages and the like.

In the embodiment of the invention, if the threshold judgment module judges that abnormal data currently occurs, the MEMS wake-up module can be started. The MEMS wake-up module can be pre-configured with data acquisition frequency and data reporting frequency in an alarm state, wherein the data acquisition frequency in the alarm state is higher than the preset data acquisition frequency, for example, continuous acquisition can be realized, for example, the acquisition is performed every 1 s.
