Once a fire occurs, the camera can accurately track, but the accurate coordinates of the ignition point are affected by various factors (magnetic deflection angle difference and magnetic field interference of each field), the accurate coordinates are not accurate all the time, and the more the distance is, the larger the deviation of the accurate position of the ignition point is likely to be, so that the ignition is caused. Resulting in insufficiently accurate monitoring of e.g. the location of the ignition point.

And further, the high-efficiency and accurate preset scene monitoring is realized, and powerful support is provided for timely finding and processing abnormal conditions.

Specifically, referring to fig. 1, the monitoring system 10 based on the beidou-R pan-tilt 11 provided by the present utility model is mainly used for monitoring the situation of a preset scene (forest). The monitoring system 10 is deployed at different monitoring points (such as on a forest tower) of a preset scene through a plurality of Beidou-R cloud platforms 11, so as to acquire accurate positioning information of each Beidou-R cloud platform 11, and the accurate positioning information is respectively pointed to the reference cloud platform through a first antenna 12 and a second antenna 13. And the first resolving unit 14 and the second resolving unit 15 respectively resolve the azimuth angles of the two antennas pointing to the reference holder (the resolving can be performed by a processor built in the resolving unit or by a control unit, and the determining can be performed by the actual condition of the device, and any existing resolving method can be adopted). The control unit 16 is in communication connection with each component of the system and is responsible for generating the holder coordinates of the reference holder to construct the holder coordinates into RTK reference stations as are common in the existing RTK positioning, the accurate holder coordinates of the reference holder are obtained through the first antenna 12 and the second antenna 13, and one reference station is arranged in the provided system, so that the existing reference correction method can be rapidly applied to the provided system to complete rapid positioning of a plurality of Beidou-R holders 11, and a large amount of time is required to be consumed for positioning the Beidou-R holders 11 one by one.

Furthermore, the control unit 16 can calculate the base cradle head coordinates given the distance and the respective azimuth and coordinates of the first antenna 12 and the second antenna 13, in combination with the usual triangulation technique. The provided monitoring system 10 can more accurately determine the position of the reference cradle head through two antennas and corresponding resolving units, and the monitoring precision is improved. Meanwhile, the control unit 16 can also receive monitoring information sent by the Beidou-R cradle head 11 in real time, and ensure quick response to abnormal conditions. The arrangement of multiple Beidou-R holders 11 allows the monitoring system 10 to cover a wide monitoring area, adapting to scenes of different sizes and complexities. The monitoring system 10 reduces human intervention and improves monitoring efficiency by automatic calculation and coordinate generation.

And the monitoring system 10 can be applied to various scenes needing accurate monitoring, such as urban management, environment monitoring, safety protection and other fields. And the architecture of the monitoring system 10 allows for future additions of more holders or optimization algorithms to enhance monitoring capabilities as needed.

In summary, the provided monitoring system 10 realizes efficient and accurate preset scene monitoring by combining the Beidou-R technology and accurate antenna positioning, and provides powerful support for timely finding and processing abnormal conditions.

Meanwhile, it should be noted that, in the present utility model, the control unit 16 generates the pan-tilt coordinates of the beidou-R pan-tilt 11 to be positioned, and also receives the monitoring information of the preset scene sent by the beidou-R pan-tilt 11. The utility model aims to design a monitoring system 10 based on a Beidou-R cradle head 11 by combining a conventional Beidou positioning method (or GNSS positioning method) and a ranging method, for example, acquiring azimuth angles corresponding to a first antenna 12 and a second antenna 13 and distances between the first antenna 12 and the second antenna 13 by combining a mature triangular positioning technology, and further acquiring coordinates of the first antenna 12 and the second antenna 13 by combining Beidou positioning so as to determine the coordinates of the Beidou-R cradle head 11 by combining the triangular positioning technology. The present utility model therefore aims to improve the accurate positioning of the Beidou-R head 11 by the design of the first antenna 12 and the second antenna 13. Meanwhile, when the Beidou-R cradle head 11 monitors fire (such as acquiring corresponding temperature through a thermal imaging method), the distance between the Beidou-R cradle head 11 and the fire point is also a very common technology in the field, the utility model aims to enable more excellent anomaly monitoring algorithms to be integrated in the Beidou-R cradle head through the accurate positioning of the Beidou-R cradle head by the provided system, so that the structure provided by the utility model can be matched with the existing method to realize the accurate positioning of the Beidou-R cradle head.

Meanwhile, by setting a reference cradle head in the plurality of Beidou-R cradle heads 11, the control unit 16 acquires satellite broadcast signals transmitted by Beidou satellites received by each Beidou-R cradle head 11, and generates resolving coordinates corresponding to each Beidou-R cradle head according to the satellite broadcast signals, which can be realized through a very mature RTK resolving algorithm. And generating correction information, namely correcting satellite positioning results by combining the resolving coordinates of the reference holder and the holder coordinates, wherein the generation of the correction information also belongs to a common method in RTK positioning. The control unit 16 can further complete the calculation coordinate correction of each beidou-R pan-tilt 11 except the reference pan-tilt according to the correction information, such as a common RTK correction method, and accurately determine the position corresponding to each beidou-R pan-tilt 11. The method provides guarantee for the accuracy of abnormality monitoring by subsequently applying the Beidou-R cradle head 11.

It should be noted that, the correction of positioning the rest stations by setting the base station belongs to a common technology in the field of Beidou/GNSS positioning, for example, the correction of satellite positioning of the rest sub-stations by combining with the RTK positioning calculation and the RTK base station technology through the base station set at a fixed position can further improve the positioning accuracy. However, in a forest or other areas with poor environmental conditions, there is no method for ensuring that each area has a base station, and the present application aims to combine the existing RTK calculation technology and base station technology to determine a reference pan-tilt in a plurality of beidou-R pan-tilt 11, and after the system for positioning multiple antennas provided by the present application is combined with the present application to quickly complete the accurate positioning of a reference pan-tilt, the present base station correction method can be combined, and the coordinates of the base station after the satellite broadcast signals received by the base station are calculated by the coordinates of the base station, so as to confirm the deviation of positioning the satellite broadcast signals, where the related methods are all very common techniques in the field. The application aims to complete the positioning of a plurality of Beidou-R cloud platforms 11 by combining the provided first antenna 12, second antenna 13, first resolving unit 14 and second resolving unit 15 with the existing positioning technology, and then rapidly combining the existing base station correction method after the accurate positioning of a single reference cloud platform is completed. The application can greatly improve the efficiency of positioning a plurality of Beidou-R cloud platforms 11 in the system by structurally improving the application and combining the existing method. The structure of the application can provide great convenience.

In some embodiments, the Beidou-R head 11 located at the geometric center of the plurality of Beidou-R heads 11 serves as a reference head. And the reference cradle head is closest to the rest cradle heads, so that the accuracy of the result of coordinate correction is improved. Meanwhile, if the provided system range is too large, the system can be divided into a plurality of subsystems, and each subsystem comprises a reference cradle head.

In some embodiments, the first resolving unit 14 comprises: the first sub-antenna 141, the first sub-antenna 141 is set up between first aerial 12 and reference cradle head, the azimuth angle that first sub-antenna 141 corresponds to first aerial 12 is the first azimuth angle; the second resolving unit 15 includes: the second sub-antenna 151, the second sub-antenna 151 is disposed between the second antenna 13 and the reference pan/tilt, and the azimuth angles corresponding to the second sub-antenna 151 and the second antenna 13 are the second azimuth angles.

As shown in fig. 2, the first sub-antenna 141 is installed between the first antenna 12 and the reference cradle head to be positioned. By pointing the reference head together with the optical axes of the first sub-antenna 141 and the first antenna 12, for example, the purpose is to measure the azimuth angle corresponding to the first antenna 12, i.e. to coincide with the first azimuth angle of the reference head to which the first antenna 12 is pointed. And is also installed between the second antenna 13 and the Beidou-R holder 11 to be positioned through the second sub-antenna 151, and points to the reference holder through, for example, the optical axes of the second sub-antenna 151 and the second antenna 13 together. The function of this is to measure the azimuth angle corresponding to the second antenna 13, i.e. in correspondence with the second azimuth angle of the reference pan-tilt to which the second antenna 13 is directed. The sub-antennas (first sub-antenna 141 and second sub-antenna 151) are then placed between the corresponding antennas (first antenna 12 or second antenna 13) and the reference pan/tilt, meaning that the sub-antennas are part of the antenna system for accurate resolution of azimuth angles. Each sub-antenna is associated with its corresponding antenna and calculates the exact azimuth of the antenna pointing to the reference pan-tilt to achieve accurate positioning. By introducing the sub-antenna and the positioning resolving function thereof, the azimuth determining precision of the monitoring system 10 based on the Beidou-R cradle head 11 is further enhanced, and the overall stability and reliability of the system are improved.

In addition, the first antenna 12 and the first sub-antenna 141 can be configured into a dual antenna, and the method for resolving the azimuth by one measurement position of the dual antenna belongs to a common technology in the art, and the present utility model aims to combine the structural arrangement of the first sub-antenna 141 and the second sub-antenna 151 on the basis of the first antenna 12 and the second antenna 13, so as to achieve accurate acquisition of the coordinates of the beidou-R cradle head by combining the existing azimuth resolving method.

The fourth antenna 152 is disposed on the second antenna 13 and is used for measuring a second azimuth angle corresponding to the second antenna 13. The accuracy and efficiency of the system are optimized by measuring the orientation of the antenna directly in combination with the Beidou positioning technique.

In addition, before the third antenna 142, the first antenna 12 and the beidou-R cradle head are physically arranged, so that the optical axes of the third antenna 142, the first antenna 12 and the beidou-R cradle head face a direction, the direction of the third antenna 142 relative to the first antenna 12 is obtained, which belongs to a general technology in the art, and the present embodiment aims to provide a method for setting the third antenna 142 and the fourth antenna 152 relative to the first antenna 12 and the second antenna 13, so as to accurately obtain the first azimuth angle and the second azimuth angle by combining the existing methods.

Therefore, both the above embodiments provide 2 system settings for acquiring the first azimuth angle and the second azimuth angle in combination with the structural design, so that the system provided by the embodiment of the application can quickly acquire the corresponding azimuth angle under any environment.

It should be noted that, the first antenna 12, the third antenna 142, the second antenna 13, and the fourth antenna 152 respectively form two groups of two antenna modules, such as the existing dual antenna module, in which one antenna measurement position and one antenna measurement azimuth are very mature technologies in the Beidou/GNSS positioning, and the present application aims to provide two structures corresponding to the two systems, which can quickly obtain the corresponding first azimuth angle and the second azimuth angle under specific environments. In some embodiments, the system further comprises: the early warning module 17, the early warning module 17 and the control unit 16 are in communication connection, the control unit 16 also receives monitoring information sent by any Beidou-R cradle head 11, and the control unit 16 controls the early warning module 17 to send out an alarm when the monitoring information is determined to be abnormal.
