[0029] like Figure 1-6 As shown, a high slope displacement safety detection device provided by the present invention comprises: a detector 1 installed outside the edge of the high slope, locators 2 installed at different positions on the high slope, and a display terminal, wherein the number of the locators 2 is at least three, and the plurality of the locators 2 form a geometric polygon;

[0030] The locator 2 includes a frequency generator 2-2, and the frequencies of the electromagnetic waves emitted by the frequency generator 2-2 on each locator 2 are different;

[0031] The detector 1 includes a frequency detector 1-6 and a first processor 1-3; the frequency detector 1-6 is used to receive the electromagnetic waves emitted by the frequency generator 2-2 and determine the position and frequency of the electromagnetic waves emitted; the first processor 1-3 is used to determine the position of each locator 2 according to the position and frequency of the frequency generator 2-2 determined by the frequency detector 1-6, obtain the geometric polygon formed by each locator 2, and determine whether the displacement of the high slope is safe based on the gap between the geometric polygons at adjacent moments, and send the safety of the displacement of the high slope to the display terminal through wireless communication technology.

[0032] During construction, workers place the present invention according to the terrain. As long as the detector 1 can receive the electromagnetic wave signal of the locator 2, there are no excessive restrictions on the location. At the same time, the power consumption of the frequency generator 2-2 is low, so there is no need to overly consider its power supply needs. At the same time, the invention does not have excessive requirements for the locations of the detector 1 and the locator 2, which increases the convenience of construction and placement, and does not have high requirements for the terrain.

[0033] In the present invention, the detector 1 is used as the main working component. Different locators are determined according to the frequency of electromagnetic waves, and the orientation and distance of the locator 2 from the detector 1 are determined according to the signal strength of the electromagnetic waves received at different frequencies, so as to further determine the position of the locator 2, and then a polygon with each locator 2 as the vertex is constructed at the same time. By comparing the difference between the two polygons before and after, the deformation degree of the polygon is obtained, and whether the displacement of the high slope is safe is determined according to the deformation degree of the polygon, and the result is sent to the display terminal for construction personnel to watch in real time on the display terminal. The display terminal can always remind the construction personnel by means of an alarm based on the result, and the construction personnel observe whether maintenance is needed according to the on-site conditions.

[0034] In the present invention, the wireless communication technology may be GPRS technology, or other communication technologies may be used, and the display terminal may be an APP installed on a mobile phone, or a real operating platform located in a central control room.

[0035] For the specific product structure at the construction site, in order to facilitate installation and improve construction efficiency, the present invention provides the specific structure of the detector 1 and the specific structure of the positioner 2 respectively.

[0036] In the present invention, the detector 1 also includes a first support rod 1-1 for being inserted on the outside of the edge of the high slope, the first support rod 1-1 is provided with the first processor 1-3, the first support rod 1-1 is also provided with a first power supply 1-2, the top of the first support rod 1-1 is provided with a universal guide head 1-5, the universal guide head 1-5 is slidably connected with the frequency detector 1-6, the frequency detector 1-6 slides universally on the universal guide head 1-5, and the first power supply 1-2 supplies power to the first processor 1-3 and the frequency detector 1-6.

[0037] The first support rod 1-1 can fix the detector on the outside of the high slope edge. Since the outside of the high slope edge is generally soil, it is generally fixed by insertion. The universal guide head 1-5 provides a platform for the frequency detector 1-6 to adjust the detection direction. The frequency detector 1-6 is used to receive electromagnetic wave signals and determine the frequency and intensity of the electromagnetic wave. The frequency of the electromagnetic wave is used to distinguish different locators 2, and the intensity of the electromagnetic wave is used to determine the position of the locator, that is, the direction and distance of the locator 2 relative to the detector 1.

[0038] In order to further accurately represent polygons and provide accuracy in judging the degree of deformation of polygons, a position sensor 1-4 is introduced in the present invention to determine the three-dimensional position coordinates of the detector 1, wherein a position sensor 1-4 is also provided on the first support rod 1-1, and the position sensor 1-4 is used to obtain the current position of the detector 1, and the first processor 1-3 is also used to determine the position coordinates of the geometric polygons at adjacent moments according to the position obtained by the position sensor 1-4, thereby reducing the difference between the geometric polygons at adjacent moments.

[0039] Since the position sensor 1-4 obtains the three-dimensional coordinates of the position of the detector 1, that is, the three-dimensional coordinates of the position of the universal guide head 1-5 on the detector 1, combined with the direction and distance of the locator 2 obtained above, the three-dimensional coordinates of the locator 2 can be determined in combination with the coordinates of the detector 1, and then the three-dimensional coordinates of each locator 2 can be obtained, and then the coordinates of each vertex of the polygon can be determined. In the subsequent deformation degree detection, the deformation degree of the polygon can be determined by the displacement of the three-dimensional coordinates, and the difference between the geometric polygons at adjacent moments can be determined.

[0040] Regarding the structure of the frequency detector 1-6, the present invention proposes an implementation method, wherein the frequency detector 1-6 includes a body 1-61, a universal driving wheel 1-63 and a magnet 1-62 are arranged at the bottom of the body 1-61, the magnet 1-62 is evenly arranged around the circumference of the bottom of the body 1-61, a frequency detection head 1-66 is arranged at the top of the body 1-61, and a second processor 1-67 and a battery 1-65 are also arranged on the body 1-61;

[0041] The second processor 1-67 is used to control the universal drive wheel 1-63 to move arbitrarily on the universal guide head 1-5, and at the same time receive the frequency and intensity of the electromagnetic waves detected by the frequency detection head 1-66 in real time, determine the frequency and direction of the electromagnetic waves of each frequency according to the frequency and intensity of the electromagnetic waves detected by the frequency detection head 1-66, and transmit the frequency, direction and intensity of the electromagnetic waves of each frequency to the first processor 1-3, and the battery 1-65 is used to power the second processor 1-67, the frequency detection head 1-66 and the universal drive wheel 1-63.

[0042] When working, the second processor 1-67 determines the frequency, direction and intensity of the electromagnetic wave according to the frequency and intensity detected by the frequency detection head 1-66, and the first processor 1-3 determines the position of the locator 2. When determining the direction of the electromagnetic wave, the frequency detector 1-6 of the present invention determines the point with the strongest intensity of the electromagnetic wave of the current frequency by changing its position, and then determines the direction of the ray of the ball center of the universal guide head 1-5 passing through this point as the direction of the electromagnetic wave, intercepts the intensity of the electromagnetic wave in the rigid direction, and obtains the intensity of the electromagnetic wave, and then obtains the direction and intensity of the electromagnetic wave of each frequency.

[0043] At the same time, in the present invention, the magnet can make the frequency detector 1-6 stick to the universal guide head 1-5 and move on the surface of the universal guide head 1-5.

[0044] In order to more conveniently power the frequency detector 1-6, the present invention introduces the electric energy of the first power supply 1-2 to provide electric energy for the frequency detector 1-6. The material of the universal rail guide head 1-5 is iron, and the first power supply 1-2 provides electric energy for the surface of the universal rail guide head 1-5.

[0045] The frequency detector 1-6 also includes an electric connecting rod 1-64, one end of which is connected to the charging end of the battery 1-65, and the other end of the electric connecting rod 1-64 is always in contact with the surface of the universal guide head 1-5.

[0046] The connecting rod 1-64 plays the role of transmitting electric energy, and conducts the electric energy on the surface of the universal guide head 1-5 into the battery 1-65 of the frequency detector 1-6, thereby providing electric energy for the frequency detector 1-6.

[0047] In the present invention, the movement of the frequency detector 1-6 provides another implementation mode, and the surface of the universal rail guide head 1-5 is provided with a spiral track for limiting the displacement track of the frequency detector 1-6. The spiral track can effectively limit the position of the frequency detector 1-6, and can also ensure that the frequency detector 1-6 can also stay at any position of the universal rail guide head 1-5.

[0048] In the present invention, triangles are used as polygons for edge calculation, and therefore, the number of the locators 2 is three.

[0049] The present invention relates to the structure of the locator 2, wherein the locator 2 also includes a second support rod 2-1 for being inserted on the high slope and a second power supply 2-3 for supplying power to the frequency generator 2-2, wherein the frequency generator 2-2 is arranged on the top of the second support rod 2-1, and the second power supply 2-3 is arranged on the second support rod 2-1.

[0050] In order to facilitate disassembly, installation and replacement during construction, the frequency generator 2-2 is detachably connected to the second support rod 2-1.

[0051] In the present invention, both the first power source 1-2 and the second power source 2-3 are solar cells, which can adaptively power themselves in high slope areas without the need for additional wiring at the construction site, thus facilitating construction and subsequent maintenance.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
