most of the existing slope deformation observation systems are realized by means of GNSS technology, but peripheral monitoring or protective equipment such as a flood gate is not combined for assisting observation, so that the following two problems are caused:
on one hand, if the GNSS technology is used for controlling the on-site protective equipment, the 'trust' of the protective equipment to the system can be reduced when misjudgment occurs, and the reduction of the 'trust' only affects the service life of the protective equipment (especially for some large-scale electric equipment, the service life and the resource consumption are very large when the protective equipment is started once) and cannot be controlled by the system due to the reduction of the 'trust';
on the other hand, if peripheral monitoring equipment is adopted for feedback, the feedback working process is complicated, and the generation time of the final action is influenced.

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, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The damage caused by the deformation of the slope is very dangerous, and if the deformation prediction is not carried out on the slope in some special areas, the condition of the slope is difficult to know, although some devices are used for protection, such as: the flood barrier gate can only be closed in advance to play a protection role;
most of the existing slope deformation observation systems are realized by means of GNSS technology, but peripheral monitoring or protection equipment such as a flood gate is not combined for assisting observation.
To this end, the present invention provides an alarm monitoring system for predicting slope deformation through GNSS observation perception, as shown in fig. 1, which includes a control platform 100, a GNSS observation module 200, and peripheral devices 500, where the peripheral devices 500 include a total station, a flood barrier, a TDR, an osmometer, etc. (a peripheral protection device or a peripheral monitoring device), and wherein: the output end of the control platform 100 is connected to the GNSS observation module 200, and is configured to output observation instruction information thereto; the output end of the control platform 100 is further connected to a peripheral device 500, and the peripheral device 500 receives the warning instruction information output by the control platform 100 and performs a preparation action triggered by the warning instruction information, for example: powering of the device (but not starting the device), or monitoring of the device (in preparation for starting the device);
the warning monitoring system further comprises a slope deformation prediction platform 300 and an early warning monitoring platform 400, wherein: the slope deformation prediction platform 300 and the early warning monitoring platform 400 are both connected with the output end of the GNSS observation module 200, the slope deformation prediction platform 300 is used for receiving observation perception information output by the GNSS observation module 200 at one time, predicting a deformation value of a deformed slope according to the observation perception information output at one time, and controlling the platform 100 to output warning instruction information when the slope deformation value exceeds a safety threshold;
meanwhile, the GNSS observation module 200 performs secondary output of observation sensing information to the early warning monitoring platform 400, and the early warning monitoring platform 400 monitors the deformed slope by means of the observation sensing information output secondarily, so as to skip the control platform 100 after the warning instruction information is confirmed, and enable the peripheral device 500 in preparation to perform an early warning action.
It should be noted that, the GNSS observation module 200 performs static observation in the observation sensing information output at one time in a double-base-point manner; the GNSS observation module 200 performs dynamic observation using a multi-base point method on the observation sensing information that is secondarily output.
When in work:
firstly, the control platform 100 controls the GNSS observation module 200 to perform observation, because the observation at this time is not targeted, only the slope deformation condition of the whole area is observed, the observation under the normal state is all static observation by adopting a double-base-point mode, and the adjustment result of observation data directly uses WGS84 coordinates, the normalization under the BJ54 ellipsoid is abandoned, so as to avoid the system error (for example, the system error caused by coordinate conversion, resolving rotation parameters and scale factors) caused by result bringing, the WGS84 geodetic coordinates of the double base points after unconstrained adjustment are regarded as fixed coordinates under the WGS84 ellipsoid reference, so that the double base points are always used as observation coordinates in the observation process, thereby ensuring the consistency of the whole observation result (namely observation sensing information output once), because the observation range under the normal state is larger, if more work loads are more, the double-base-point mode is adopted, preferably the second and fourth equally divided points among the five points taking the base points are used as the observation coordinates, and the situation of the slope sensing information output once is not considered, and the situation of a certain specific area is not considered, so that the alarm can be equal divided, the consistency of the slope observation result can be ensured, and the safety deformation value can be set as a prediction threshold value can be conveniently set under the platform 100, and the safety deformation prediction value can be conveniently output under the slope deformation condition of the slope deformation of the platform;
in addition, static observation is embodied by a base point of a fixed position;
then, the peripheral device 500 receives the warning instruction information and performs a preparation action triggered by the warning instruction information, once the preparation action is performed, the peripheral protective device has the capability of rapidly performing an early warning action, and the peripheral monitoring device starts to work to prepare for a subsequent early warning action;
when the slope deformation value exceeds the safety threshold, the control platform 100 outputs the warning instruction information, and the GNSS observation module 200 performs secondary output of observation sensing information to the warning monitoring platform 400 (the secondary output also includes the deformed slope predicted by the slope deformation prediction platform 300), and the warning monitoring platform 400 monitors the deformed slope by means of the observation sensing information output secondarily, that is, the deformed slope is determined by observation in a normal state, at this time, the monitoring area range is reduced, but the monitoring capability needs to be improved, so that dynamic observation needs to be performed in a multi-base-point manner in the observation sensing information output secondarily, the monitoring area range is reduced by a plurality of base points, dynamic observation can be performed among the plurality of base points, and data such as weather, humidity, temperature and the like in the area range are introduced, so that no specific standard exists, the obtained monitoring result is more representative, and the warning instruction information is confirmed by the result, so that once the warning instruction information is verified, the control platform 100 is skipped to enable the peripheral device 500 in preparation to perform the warning action.
In fig. 2, the control platform 100 includes a prediction receiving unit 110, an observation output unit 120, and a device output unit 130, the observation output unit 120 outputs observation instruction information to the GNSS observation module 200, and receives a deformation value predicted by the slope deformation prediction platform 300 according to observation perception information output once through the prediction receiving unit 110, and the device output unit 130 outputs warning instruction information to the peripheral device 500 when the deformation value exceeds a safety threshold.
In the present embodiment, the observation output unit 120 outputs the observation instruction information to the GNSS observation module 200 in a real-time output manner, which has an advantage of predicting the deformation value in time.
In yet another embodiment, the observation output unit 120 outputs the observation instruction information to the GNSS observation module 200 in an intermittent output manner, that is, in this embodiment, an intermittent time needs to be set according to the actual situation, and then the GNSS observation module 200 observes at each node (initial node or final node) of the intermittent time, so that not only is the observation continuity ensured, but also a buffering time is provided for prediction, the workload of the GNSS observation module 200 is reduced, and an intermittent loop is formed by cooperating with the prediction receiving unit 110.
Furthermore, after the warning instruction information is output, the next output of the observation output unit 120 is performed after the last secondary output is formed, that is: the slope deformation prediction platform 300 predicts the observation perception information output for the first time to obtain a deformation value, and the deformation value exceeds a safety threshold, at this time, the GNSS observation module 200 performs secondary output of the observation perception information to the early warning monitoring platform 400 in combination with an area (namely, a deformation slope) predicted by the slope deformation prediction platform 300, at this time, each time of output has corresponding secondary output, so that in the embodiment, the next time of output can be performed only after the secondary output corresponding to the current time of output is completed, and the secondary output cannot be blocked or output is omitted.
In addition, after the warning instruction information is output, the peripheral device 500 remains connected to the device output unit 130, so as to output the deformation value subsequently received by the prediction receiving unit 110 to the peripheral device 500 through the device output unit 130, which enables the peripheral device 500 to generate continuous data information (generated according to the deformation value), and then the generated data information is fed back to the slope deformation prediction platform 300 to form a primary feedback, and the slope deformation prediction platform 300 incorporates the primary feedback data information when predicting the deformation value of the deformation slope, so that the most direct data of the deformation slope field can be obtained by using the peripheral monitoring device preparation stage on the basis of the observation of the GNSS observation module 200, so as to assist the slope deformation prediction platform 300 to perform prediction, thereby improving the representativeness and accuracy of the prediction.
In addition, the peripheral device 500 also monitors the generated monitoring information according to the early warning monitoring platform 400, and feeds the monitoring information back to the early warning monitoring platform 400 to form secondary feedback, and similarly, the most direct data of the deformed slope field is obtained through the preparation stage of the peripheral monitoring device, so that the monitoring accuracy of the early warning monitoring platform 400 is improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
