[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be described in detail below with reference to the drawings and specific embodiments.

[0024] In the specific embodiments, each specific technical feature in each embodiment can be combined in various ways without contradiction, for example, different specific technical features can form different embodiments through combination, in order to avoid unnecessary repetition, various possible combinations of each specific technical feature in the present application will not be described again.

[0025] Here, it also needs to be explained that, in order to avoid the present application being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0026] In addition, it needs to be explained that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. In the following description, the term "first\second\..." only distinguishes different objects, and does not mean that the objects have the same or relationship. It should be understood that the orientation described by the orientation terms "above", "below", "inside", "outside" and the like is the orientation in the normal use state.

[0027] In the following specific embodiments, the displacement monitoring system based on the Beidou sensing device is applied to the tension net, the intrusion behavior in the area surrounded by the tension net is monitored by monitoring the displacement of the tension net, and the alarm signal is triggered when the displacement of the tension net at any position exceeds the displacement threshold, so as to realize the monitoring of the intrusion. The structure and function of the displacement monitoring system based on the Beidou sensing device are exemplarily illustrated in combination with each embodiment.

[0028] In some embodiments, as Figure 1As shown, the displacement monitoring system based on the Beidou sensing device comprises a first monitoring device 10, a reference station 20, a monitoring component 30 and a satellite device 40. The first monitoring device 10 has a plurality of first monitoring devices 10 arranged at intervals along the extension direction of the tension net, and each first monitoring device 10 is fixedly connected with the tension net. When the tension net deforms at the position where the first monitoring device 10 is arranged, the tension net drives the first monitoring device 10 to move, so that the position of the first monitoring device 10 changes. The reference station 20 is used to obtain the position information of each first monitoring device 10. The position information of each first monitoring device 10 obtained can determine whether the tension net deforms, so as to determine whether there is an intrusion behavior to the tension net through the deformation state. Moreover, a plurality of reference stations 20 are arranged at intervals along the extension direction of the tension net, so that a plurality of first monitoring devices are located between adjacent reference stations 20. It can be understood that a plurality of adjacent first monitoring devices 10 form a first monitoring group, and each first monitoring device 10 forms a plurality of first detection groups. Each first detection group is used to monitor the deformation of the tension net in different ranges. A plurality of reference stations 20 are respectively used to receive the position information of each first detection group, so as to monitor the intrusion behavior of the tension net in different ranges by each reference station 20 and each first detection group. It should be noted that the reference station 20 determines the position of the first monitoring device 10 by detecting the distance between the first monitoring device 10 and the reference station 20. If the first monitoring device 10 is arranged far away from the reference station 20, not only will it cause difficulty in signal transmission between the first monitoring device 10 and the reference station 20, but also the absolute distance between the first monitoring device 10 and the reference station 20 will be large. When the first monitoring device 10 has a small range displacement, the displacement is very small relative to the absolute distance, so that the small range displacement is difficult to be detected, that is, the sensitivity to the intrusion behavior of the tension net is reduced. By grouping the first monitoring devices 10 and monitoring the displacement of each first monitoring device 10 in each first monitoring group by the reference station 20, the distance between each first monitoring device 10 and the reference station 20 can be kept within a small range, so that the displacement monitoring system has high sensitivity to the intrusion behavior of each region of the tension net.

[0029] Meanwhile, a plurality of monitoring components 30 are arranged at intervals along the extension direction of the tension net, and the satellite device 40 is used to obtain the position information of each monitoring component. It can be understood that the monitoring component 30 can also obtain the displacement of the tension net, but the monitoring component 30 obtains the absolute position information in the earth coordinate system, that is, the latitude and longitude information at the position of the tension net where the monitoring component 30 is arranged. The satellite device 40 can obtain the latitude and longitude information of each monitoring component 30 to calculate the deformation of the tension net, so as to determine the intrusion behavior to each region of the tension net.

[0030] It should be noted that the first monitoring device 10 is used to determine the intrusion behavior to the tension net through the relative position relationship with the reference station 20, the monitoring assembly 30 is used to determine the intrusion behavior to the tension net through the absolute position information in the earth coordinate system, that is, through the combination of the relative position information of the first monitoring device 10 and the absolute position information of the tension net, the intrusion behavior to the tension net can be determined more sensitively to detect the intrusion behavior to the tension net.

[0031] The utility model embodiment provides a kind of displacement monitoring system based on big dipper sensing device, the displacement monitoring system based on big dipper sensing device includes first monitoring device and reference station, multiple first monitoring devices are spaced apart along the extension direction of tension net, and it is fixedly connected with tension net, and the displacement of tension net can be determined by the relative position relationship of first monitoring device and reference station;While displacement monitoring system based on big dipper sensing device also includes monitoring assembly and satellite device, monitoring assembly is spaced apart along the extension direction of tension net, for obtaining the absolute position information of tension net, satellite device is used to obtain each absolute position information and obtains the deformation of tension net, by the relative displacement information of first monitoring device and reference station and the deformation of tension net that the absolute position information of tension net is calculated, the displacement of tension net can be determined with higher accuracy, so as to make the sensitivity of intrusion monitoring of tension net higher.

[0032] In some embodiments, as shown in Figure 1 Tension net includes multiple protection areas and each protection area is sequentially connected, each protection area includes multiple first monitoring devices 10 and a reference station 20, the reference station 20 is used to provide the reference of position information for the protection area, each first monitoring device 10 determines the displacement condition of tension net by monitoring the relative position relationship with reference station 20, reference station 20 is located in the middle of protection area, so that the spacing of each first monitoring device 10 and reference station 20 is within distance threshold, so that each first monitoring device 10 has higher sensitivity to the deformation of tension net.

[0033] In some embodiments, as shown in Figure 2 Monitoring assembly 30 includes monitoring antenna 31, monitoring antenna 31, monitoring antenna 31 is used to send position signal to satellite device 40, each monitoring antenna 31 is spaced apart along the extension direction of tension net, and is fixedly connected with tension net, it can be understood that monitoring antenna 31 is directly fixed to tension net, monitoring antenna 31 can directly obtain the absolute position data of tension net and directly emit absolute position data to satellite device 40.

[0034] Optionally, as shown in Figure 2As shown, the monitoring antenna 31 is fixed to each of the first monitoring devices 10. That is, the monitoring antenna 31 is fixed to the tension network through the first monitoring device 10. Based on the existing first monitoring device 10 and reference station 20 in the tension network, the existing tension network displacement monitoring system can be modified by fixing the detection antenna 31 to each of the first monitoring devices 10 without removing the first monitoring device 10. This makes it easier to modify and upgrade the existing tension network displacement monitoring system.

[0035] Optional, such as Figure 3 As shown, the monitoring antenna 31 is fixed to the first monitoring device 10 closest to the edge of the protected area among all the first monitoring devices 10. It can be understood that the monitoring antenna 31 is fixedly connected to the tension net through the first monitoring device 10. Moreover, the monitoring antenna 31 is only connected to the first monitoring device 10 closest to the edge of the protected area. That is, the monitoring antenna 31 is only fixed to the first monitoring device 10 farthest from the base station 20. It can be understood that the distance between the first monitoring device 10 located at the edge of the protected area and the base station 20 is the largest. The sensitivity to deformation detection of the tension net is the lowest at this location. By fixing the monitoring antenna 31 to the first monitoring device 10 at this location, the position information obtained by the monitoring antenna 31 is the absolute position information in the Earth coordinate system. Its sensitivity is independent of the setting position of the base station 20. By using this absolute position information as a supplement to the relative position information, it is possible to detect intrusion behavior at the edge of the tension net with higher sensitivity.

[0036] In some embodiments, such as Figure 4As shown, the monitoring assembly 30 comprises a second monitoring device 32 and a satellite receiver 33, a plurality of second monitoring devices 32 are arranged at intervals along the extension direction of the tension net and are fixedly connected with the tension net, and the satellite receiver 33 is used for being connected with each second monitoring device 32 and is used for sending position information to the satellite device 40. It can be understood that the second monitoring device 32 is only used for obtaining absolute position information of the tension net, and the absolute position information does not need to be sent to the satellite device 40 by the second monitoring device 32, but the satellite receiver 33 sends the absolute position information to the satellite device 40 after obtaining the absolute position information from each second monitoring device 32. By making the second monitoring device 32 not need to undertake the long-distance data transmission function, the structure of the second monitoring device 32 can be simplified, so as to reduce the weight of the second monitoring device 32. It needs to be explained that since the second monitoring device 32 is directly fixed to the tension net, the greater the self-weight of the second monitoring device 32, the more difficult the deformation of other positions of the tension net causes the position change of the second monitoring device 32, that is, the greater the self-weight of the second monitoring device 32, the less sensitive the monitoring of the intrusion behavior of the tension net is. By reducing the weight of the second monitoring device 32, the sensitivity of the intrusion monitoring of the tension net can be further improved. Moreover, the second monitoring device 32 is directly fixed to the tension net instead of being fixed to the tension net through the first monitoring device 10, so that the setting position of the second monitoring device 32 is more flexible.

[0037] Optionally, as shown in Figure 4 The tension net comprises a plurality of protection areas and each protection area is sequentially connected, a plurality of second monitoring devices 32 and one satellite receiver 33 are arranged in each protection area, and each second monitoring device 32 sends the absolute position information of the tension net to the satellite receiver 33 after obtaining the absolute position information, so that the satellite receiver 33 sends the absolute position information to the satellite device 40.

[0038] Optionally, as shown in Figure 5As shown, the second monitoring device 32 is located at the edge of each protection area, and it can be understood that, in a protection area, the first monitoring device 10 closest to the edge of the protection area is farthest from the reference station 20 located at the center of the protection area, thereby making the sensitivity of the first monitoring device 10 to the displacement detection of the edge of the protection area lowest, and by arranging the second monitoring device 32 at the edge of each protection area, the absolute position information of the edge of each protection area can be directly obtained, and the deformation of the edge of the protection area can be more accurately obtained through the absolute position information, thereby further improving the sensitivity of the intrusion monitoring of the edge position of the protection area. Moreover, by directly fixing the second monitoring device 32 to the tension net instead of fixing the second monitoring device 32 through the first monitoring device 10, the second monitoring device 32 can be directly arranged at the edge of the protection area instead of being located close to the protection area, so that the second monitoring device 32 can directly obtain the absolute position information of the edge position of the protection area, thereby further improving the sensitivity of the intrusion monitoring of the edge position of the protection area.

[0039] Optionally, as shown in Figure 5 As shown, the satellite receiver 33 is located at the edge of the protection area, and the satellite receiver 33 is connected with two second monitoring devices 32 located at the edge of the protection area, and it can be understood that the satellite receiver 33 is located at the connection position of two adjacent protection areas, two second monitoring devices 32 are arranged on both sides of the connection position, and the two second monitoring devices 32 are respectively used to obtain the absolute positions of the edges of the two adjacent protection areas. The satellite receiver 33 is connected with the two second monitoring devices 32 to transmit the absolute position information of the edges of the two protection areas to the satellite device 40, that is, the two second monitoring devices 32 located at the connection position of the adjacent two protection areas share one satellite receiver 33, thereby reducing the number of satellite receivers 33 and reducing the manufacturing cost of the Beidou-based displacement monitoring system.

[0040] In some embodiments, as shown in Figure 6 As shown, the Beidou-based displacement monitoring system further comprises a micro antenna 50, and the micro antenna 50 is fixed to each first monitoring device 10 and the reference station 20, and each first monitoring device 10 and the reference station 20 can transmit signals in a straight line through the micro antenna 50, wherein the first monitoring device 10 with a distance less than a distance threshold from the reference station 20 transmits position information to the reference station 20 through the micro antenna 50, and the first monitoring device 10 with a distance greater than the distance threshold from the reference station 20 is connected with the reference station 20 through an optical fiber, and it can be understood that the first monitoring device 10 close to the reference station 20 communicates wirelessly through the micro antenna 50, thereby reducing the number of wires required by the Beidou-based displacement monitoring system, and at the same time, the first monitoring device 10 far from the reference station 20 communicates through the optical fiber, thereby making the signal transmission more reliable when transmitting signals at a long distance.

[0041] In some embodiments, as shown in Figure 6 The tension net comprises a plurality of tension wires, the plurality of tension wires are arranged at intervals along the longitudinal direction, the first monitoring device 10 extends along the longitudinal direction and is fixedly connected with each tension wire, that is, the displacement information of each tension wire can be acquired through the first monitoring device 10, and the deformation of any tension wire will change the position information of the first monitoring device 10, so that the sensitivity of the tension net intrusion monitoring is further improved.

[0042] The above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
