Description

Technical Field

[0001] This invention belongs to the field of BeiDou terminal technology, specifically relating to a BeiDou monitoring terminal and monitoring method. Background Technology

[0002] In 2009, the nation began construction of the BeiDou-3 system. The BeiDou-3 global satellite navigation system consists of 24 orbital satellites, 3 geostationary orbit satellites, and 3 inclined geosynchronous orbit satellites, totaling 30 satellites. In July 2020, the BeiDou-3 global satellite navigation system was officially launched, marking a new era of global service for BeiDou. In recent years, bridges have frequently tilted and collapsed due to vehicle overloading or inadequate management and maintenance. Moreover, not only bridges, but various structures may shift due to structural changes after prolonged use. Once displacement occurs, it can easily lead to major accidents. Therefore, BeiDou monitoring terminals are used to reduce the real-time monitoring of bridges, slopes, and some support structures, and can assess the status of monitored structures in real time, preventing danger from approaching. The Beidou monitoring terminal can issue early warnings, which can greatly reduce the probability of disasters. During detection, the Beidou monitoring terminal can perform high-precision monitoring of displacement. Currently, the monitoring targets are mainly medium and large bridges, high slopes, or structures with a strong need for surface displacement monitoring. When using the Beidou monitoring terminal, it only needs to be installed on the building and then connected to the orbital satellite. When the building is displaced, the orbital satellite will monitor the displacement status in real time. The existing Beidou monitoring terminal has poor heat dissipation performance. When working in a high-temperature environment, due to the high ambient temperature and the heat generated by the Beidou monitoring terminal itself, the Beidou monitoring terminal can easily generate a high temperature. Long-term operation at high temperatures can easily cause the internal components of the Beidou monitoring terminal to overheat and affect its service life. Therefore, it needs to be improved. Summary of the Invention

[0003] The purpose of this invention is to provide a BeiDou monitoring terminal and monitoring method that can effectively dissipate heat from the monitoring terminal body, thus avoiding the problem of shortened service life caused by the monitoring terminal body working in a high-temperature environment.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

The front and rear ends of the enclosed box have locking grooves matching the positions of the sliders.

[0009] The mounting box has two rotating rods symmetrically mounted on its bottom side. Each of the two rotating rods has a disc fixedly mounted on its upper end. Each of the two discs has several first meshing teeth arranged around its upper end. Arc-shaped plates are fixedly mounted on both sides of the rotating shaft. Several second meshing teeth are fixedly mounted on the arc surfaces of the two arc-shaped plates. The second meshing teeth on the left and right sides respectively mesh with several first meshing teeth on the left and right sides. Each of the two enclosed boxes has a moving groove matching the position of the rotating rod at one end close to each other. Each of the two enclosed boxes has a connecting groove at both its front and rear ends. A fixing plate is fixedly mounted inside each of the four connecting grooves. Each of the four fixing plates has a connection port matching the interior of the enclosed box. Four dustproof filter plates are fixedly mounted inside the four connection ports. A cleaning component is fixedly mounted inside each of the four connecting grooves.

[0010] The cleaning assembly includes two fixed blocks, which are fixedly installed on the side of the fixed plate away from the center of the enclosed box. The dust filter plate is located between the two fixed blocks. A cleaning block is slidably assembled inside the connecting groove. The cleaning block is located between the two fixed blocks. A cleaning brush is fixedly installed on one end of the cleaning block near the dust filter plate. One end of the cleaning brush abuts against the dust filter plate. A connecting rope is fixedly installed on the upper end of the cleaning block. The other end of the connecting rope extends into the mounting box and is fixedly connected to one side of the rotating rod.

[0012] Both rotating rods have a winding wheel fixedly installed on one side of their circumference, and one end of each of the two connecting ropes on the left and right sides is fixedly connected to the two winding wheels respectively.

[0013] Two protective boxes, matching the refrigeration compressor and the motor, are respectively installed on the mounting box.

[0014] The cleaning and sealing mechanism includes a mounting frame, which is installed on the upper part of the mounting box and matches the position of the dustproof plate. A matching block is slidably assembled inside the mounting frame. A cleaning cotton matching the dustproof plate is installed at the lower end of the matching block. A pull rope is installed at one end of the matching block, and the other end of the pull rope extends into the mounting box and is fixedly connected to one side of the mounting platform. A sealing cover is provided at the upper end of the mounting frame. A connecting spring is provided on one side of the matching block, and the other end of the connecting spring is fixedly connected to the mounting frame.

[0015] A monitoring method using a BeiDou monitoring terminal includes the following steps:

[0016] Step 1: First, install the installation box at the designated monitoring location. Electrically connect the controller to the external control terminal. After installation, activate the temperature sensor through the controller to monitor the internal temperature of the installation box in real time.

[0017] Step 2: Open the closed door and start the monitoring terminal. After the monitoring terminal is started, connect the external line to the monitoring terminal through the opening.

[0018] Step 3: After the monitoring terminal body is started and connected to the external line, the GNSS module inside the monitoring terminal body receives satellite signals from Beidou, GPS and GLONASS. After the monitoring terminal body is initialized, it will monitor the location in real time and transmit the location signal to the external control terminal in real time through the signal output module inside the monitoring terminal body. In this way, when the location of the monitored location is displaced, the displacement signal can be transmitted to the external control terminal in a timely manner.

[0019] Step 4: The staff pulls the two ropes by hand, and the two enclosed boxes pop out of the installation box in part. In this way, the four dust filter plates set on the left and right sides can ensure normal ventilation inside the installation box and prevent external dust from entering the installation box and adhering to the monitoring terminal body.

[0020] Step 5: When the temperature sensor detects that the internal temperature of the installation box is too high, it will send a signal to the controller through the signal output terminal. The controller will automatically control the motor, the refrigeration compressor and the two fans to start. After the two fans start, the air is directly cooled through the condenser pipe and then applied to the detection terminal body to achieve cooling. The motor output shaft drives the rotating shaft to rotate back and forth to increase the air blowing area of ​​the fan and increase the cooling effect, effectively preventing the detection terminal body from working in a high-temperature environment and affecting its service life.

[0021] When the monitoring terminal is not in use, the installation box can activate waterproof, protective, and dustproof functions. This prevents damage to the monitoring terminal from impacts or the accumulation of external water and dust, which could affect its use. Furthermore, when the internal temperature of the installation box rises, the controller can automatically activate two fans, a refrigeration compressor, and a motor to cool the monitoring terminal. The reciprocating fans have a wider airflow range, preventing localized poor heat dissipation and increasing the cooling effect. After the temperature drops, the two fans, the refrigeration compressor, and the motor can be automatically shut off to conserve cooling resources. This operating method effectively increases the service life of the monitoring terminal. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figures 1-8 As shown, the present invention includes a monitoring terminal body 1, a mounting box 11, and a controller 111. The monitoring terminal body 1 is equipped with a GNSS module. A shock-absorbing pad 12 is fixedly installed on the bottom side of the mounting box 11. A mounting plate 13 is installed on the upper end of the shock-absorbing pad 12. The monitoring terminal body 1 is fixedly installed on the front end of the mounting plate 13. The front end of the mounting box 11 has an opening that matches the interface end of the monitoring terminal body 1. The front end of the mounting box 13 has a dustproof and waterproof component that matches the position of the opening. Sliding openings are opened at both the left and right ends of the mounting box 11. A closed box 14 is slidably assembled inside each of the two sliding openings. Circular grooves that communicate with the interior of the closed box 14 are opened at both the front and rear ends of the two closed boxes 14. Dustproof filter plates 15 are fixedly installed inside each of the four circular grooves. An air inlet is installed at the upper end of the mounting box 11. A dustproof plate is installed inside the air inlet. A cleaning and sealing mechanism that matches the dustproof plate is installed at the upper end of the mounting box 11.

[0035] The mounting box 11 is equipped with a locking mechanism that matches the two enclosed boxes 14. The controller 111 is installed on the inner rear wall of the mounting box 13. The battery 16 and temperature sensor 17 are fixedly installed on the inner rear wall of the mounting box 13. A rotating shaft 18 is rotatably mounted on the upper side inside the mounting box 11. A motor 19 is fixedly installed on the left end of the mounting box 11. The output shaft of the motor 19 is fixedly connected to the rotating shaft 18. A connecting platform 20 is fixedly installed on one side of the circumference of the rotating shaft 18. A mounting platform 21 is installed at the lower end of the connecting platform 20. Two evenly spaced openings are provided at the lower end of the mounting platform 21. Two through slots 22, each with a fan 23 fixedly installed inside. A condenser pipe 24 matching the position of the two fans 23 is fixedly installed in the center of the mounting box 11. A refrigeration compressor 25 is installed at the rear end of the mounting box 11. The output end of the refrigeration compressor 25 is connected to the condenser pipe 24 through a hose. A sealing ring 261 matching the closed box 14 is fixedly installed inside each of the two sliding ports. The refrigeration compressor 25, the two fans 23, the motor 19, the battery 16 and the temperature sensor 17 are all electrically connected to the controller 111.

[0036] In its original state, the locking mechanism is locked, and the waterproof and dustproof components close the opening. The two sealed boxes 14 are completely inside the mounting box 11, and the two sealing rings 261 fill the gap between the two sealed boxes 14 and the two sliding ports, greatly increasing the sealing performance of the two mounting boxes 11 for the two sliding interfaces. In this state, the mounting box 11 is completely sealed, which can achieve the effect of waterproofing and dustproofing. When the monitoring terminal body 1 is not in use, the mounting box 11 can provide protection for the monitoring terminal body 1, preventing collisions, external water sources or external dust from entering the monitoring terminal body 1 and affecting the use of the monitoring terminal body 1.

[0037] When the monitoring terminal body 1 is needed, the installation box 1 should be fixedly installed at the installation location to be monitored. After installation, the staff opens the waterproof and dustproof components and connects the monitoring terminal body 1 to the monitoring terminal body 1 using the required external connection cable. The staff can also start the temperature sensor 17 through the controller 111 to monitor the temperature inside the installation box 11 in real time. The upper limit of the temperature detection of the temperature sensor 17 can be set through the control module of the controller 111. When the temperature sensor 17 detects that the temperature inside the installation box 11 is too high, it will automatically transmit the temperature signal to the controller 111 to achieve the purpose of timely cooling. After the installation box 11 is installed, the staff contacts the locking mechanism to lock the two closed boxes 14, so that each of the two closed boxes 14 extends out of the installation box 11, and the four circular slots are located outside the installation box 11. In this way, the four circular slots can allow natural ventilation and heat dissipation inside the installation box 11 during use. The dust filter plate 15 can prevent external dust from entering the installation box 11.

[0038] When the internal temperature of the installation box 11 is too high, the temperature sensor 17 will transmit the temperature signal to the controller 111 after detecting the high temperature. The controller 111 will then control the two fans 23, the refrigeration compressor 25 and the motor 19 to start. After the motor 19 starts, it will drive the shaft 18 to rotate back and forth. The shaft 18 will drive the two fans 23 to rotate back and forth. After the refrigeration compressor 25 starts, it will cause the condenser 24 to start cooling. The air from the fan 23 will be cooled by the condenser 24 and then act on the monitoring terminal body 1 to cool the monitoring terminal body 1 and prevent the internal parts from being damaged due to continuous operation in a high temperature environment. When the temperature drops, the temperature sensor 17 will transmit the temperature signal to the controller 111. After the temperature drops to the normal temperature, the controller 111 will control the two fans 23, the refrigeration compressor 25 and the motor 19 to shut down to save energy.

[0039] When the monitoring terminal body 1 is not in use, the installation box 11 can activate waterproof, protective, and dustproof functions. This prevents damage to the monitoring terminal body 1 from impacts or external water and dust from adhering to it, thus affecting its use. Furthermore, when the internal temperature of the installation box 11 rises, the controller 111 can automatically activate two fans 23, a refrigeration compressor 25, and a motor 19 to cool the monitoring terminal body 1. The reciprocating fans 23 have a wider airflow range, preventing localized poor heat dissipation and increasing the heat dissipation effect. After the temperature drops, the two fans 23, the refrigeration compressor 25, and the motor 19 can be automatically shut off to save on cooling resources. This operation mode can effectively increase the service life of the monitoring terminal body 1.

[0040] The dustproof and waterproof component includes a dustproof frame 26, which is fixedly installed on the inner front wall of the mounting box 11 and matches the opening. The rear end of the dustproof frame 26 abuts against the monitoring terminal body 1. The front end of the mounting box 11 is hinged with a sealing door 27 that matches the opening. A locking device is provided between the sealing door 27 and the mounting box 11. A sealing gasket matching the opening is provided on one side of the circumference of the sealing door 27. When the sealing door 27 is closed, the sealing door 27, together with the sealing gasket, can seal the opening and prevent external dust from entering the interior of the mounting box 11. When the sealing door 27 is opened, the monitoring terminal body 1 can be connected to the external connection cable, and the dustproof cover 26 can seal the interface area of ​​the monitoring terminal body 1 to prevent dust from entering the interior of the mounting box 11, thus achieving a good dustproof effect.

[0041] The locking mechanism includes two locking components, which are respectively installed on the left and right sides inside the mounting box 11. Each locking component includes two fixing platforms 28, which are respectively fixedly installed on the front and rear sides inside the mounting box 11. The front and rear ends of the enclosed box 14 are provided with storage slots 29 that match the positions of the fixing platforms 28. Each of the two fixing platforms 28 has a sliding groove 30 at one end close to each other. Sliding blocks 31 are slidably fitted inside each of the two sliding grooves 30. Each of the two sliding blocks 31 has a slope 32 at the end away from the monitoring terminal body 1. Several first springs 33 are fixedly installed at the ends of the two fixing platforms 28 away from the monitoring terminal body 1. Several first springs 33 on the front and rear sides are fixedly connected at their other ends to the inner walls of the two storage slots 29 respectively. Two second springs 34 are fixedly installed at their respective ends, and the other ends of the two second springs 34 are fixedly connected to the inner walls of the two sliding grooves 30 respectively. Pull ropes 322 are fixedly installed at their respective ends, and the ends of the two pull ropes 322 extend out of the mounting box 11 and are fixedly connected to each other. Locking grooves 321 matching the positions of the sliders 31 are provided at both the front and rear ends of the enclosed box 14. Thus, in use, when both enclosed boxes 14 are initially located inside the mounting box 11, several first springs 33... All springs 33 are in the contracted state, while the four second springs 34 are in the naturally extended state. This pushes part of the four sliders 31 out of the grooves 30. In use, the non-sloping surfaces of the two sliders 31 on the left and right sides abut against the inner wall of the locking grooves 321, thus locking the two enclosed boxes 14. When unlocking is required, the operator pulls the two pull ropes 312 upwards simultaneously. The two pull ropes 322 will simultaneously pull the four sliders 31 through their other ends, causing the four sliders 31 to retract into the four grooves 30. This will cause the first springs 33 to re-extend, pushing the two enclosed boxes 14 out of the mounting box 11 at the same time. This allows both enclosed boxes 14 to extend simultaneously, making the operation simple and convenient. When it is necessary to close the two enclosed boxes 14, both enclosed boxes 14 are pushed inwards at the same time. The two enclosed boxes 14 will simultaneously contract several first springs 33 and gradually come into contact with the inclined surfaces 32 opened by the two sliders 31. Then, the inclined surfaces 32 will generate a squeezing force on the sliders 31, causing the sliders 13 to enter the slide groove 30. Finally, when the enclosed box 14 reaches the designated position, the four second springs 34 will re-extend, pushing the sliders 31 into the locking groove 321 to complete the locking. Locking is simple and convenient, which can effectively increase the work efficiency of the staff.

[0042] The mounting box 11 has two rotating rods 331 symmetrically mounted on the bottom side. Each of the two rotating rods 331 has a disc 341 fixedly mounted on its upper end. Each of the two discs 341 has several first meshing teeth 35 arranged around its upper end. The rotating shaft 18 has arc plates 36 fixedly mounted on its left and right sides. Each of the arc surfaces of the two arc plates 36 has several second meshing teeth 361 fixedly mounted on its arc surface. The several second meshing teeth 361 on the left and right sides respectively mesh with the several first meshing teeth 35 on the left and right sides. Each of the two enclosed boxes 14 has a moving groove that matches the position of the rotating rods 331 at one end close to each other. Each of the two enclosed boxes 14 has a connecting groove 37 at both the front and rear ends. Each of the four connecting grooves 37 has a fixed plate 38 fixedly mounted inside. Each of the four fixed plates 38 has a connection port that matches the inside of the enclosed box 14. Each of the four dust filter plates 15 is fixedly mounted inside the four connection ports. Each of the four connecting grooves 37 has a cleaning component fixedly mounted inside.

[0043] The cleaning assembly includes two fixed blocks 39, which are fixedly installed on the side of the fixed plate 38 away from the center of the enclosed box 14. A dust filter plate 15 is located between the two fixed blocks 39. A cleaning block 40 is slidably fitted inside the connecting groove 37, located between the two fixed blocks 39. A cleaning brush 41 is fixedly installed on one end of the cleaning block 40 near the dust filter plate 15, with one end of the cleaning brush 41 abutting against the dust filter plate 15. A connecting rope 411 is fixedly installed on the upper end of the cleaning block 40, with the other end of the connecting rope 411 extending into the mounting box 11 and fixedly connected to one side of the circumference of the rotating rod 331. When both enclosed boxes 14 are inside the mounting box 1, the four connecting ropes 411 are not taut. When both enclosed boxes 14 are outside the mounting box 11, the four connecting ropes 411 are taut. In this state, the rotating shaft 18 moves with the motor. The output shaft of 19 reciprocates, and the two arc-shaped plates 36 also reciprocate with the reciprocating swing of the rotating shaft 18. In use, this drives several first meshing teeth 35 and several second meshing teeth 361 to mesh, causing the two rotating rods 331 to swing back and forth. This continuously causes the four connecting ropes 411 to be wound and unwound. When wound, the four connecting ropes 411 drive the four cleaning blocks 40 to move upward, which can scrape the surface of the dust filter plate 15 and compress the two third springs 401. As the four connecting ropes 411 are unwound, the two third springs 401 re-stretch and drive the cleaning brush 41 downward to clean the dust filter plate 15. This continuous cleaning of the four dust filter plates 16 can effectively prevent the filter holes of the dust filter plates 16 from becoming clogged due to long-term use, which would affect the ventilation and heat dissipation inside the installation box 11.

[0044] Two lead-line platforms 42 are fixedly installed on the upper part of each of the two enclosed boxes 14. Each of the four lead-line platforms 42 has a lead-line groove that matches the four connecting ropes 41. One end of each of the four connecting ropes 41 passes through the four lead-line grooves and is fixedly connected to one side of the circumference of the two rotating rods 33. In this way, the two lead-line platforms 42 can guide the wires and prevent the four connecting ropes 41 from being misaligned or knotted.

[0045] Two rotating rods 331 are fixedly equipped with winding wheels 43 on one side of their circumference, and one end of each of the two connecting ropes 41 on the left and right sides is fixedly connected to the two winding wheels 43 respectively; this facilitates the winding of the four connecting ropes 41.

[0046] Two protective boxes 44, matching the refrigeration compressor 25 and the motor 19, are respectively installed on the mounting box 11; this provides protection for the refrigeration compressor 25 and the motor 19.

[0047] The cleaning and sealing mechanism includes a mounting frame 45, which is installed on the upper part of the mounting box 11 and matches the position of the dustproof plate. A matching block 46 is slidably mounted inside the mounting frame 45. A cleaning cotton 47 matching the dustproof plate is installed at the lower end of the matching block 46. A pull rope 48 is installed at one end of the matching block 46, and the other end of the pull rope 48 extends into the mounting box 11 and is fixedly connected to one side of the mounting platform 21. A sealing cover 49 is provided on the upper part of the mounting frame 45. A connecting spring 50 is provided on one side of the matching block 46, and the other end of the connecting spring 50 is fixedly connected to the mounting frame 45. In use, as the mounting platform 21 swings back and forth, it can drive the connecting matching block 46 to move back and forth continuously, which in turn drives the cleaning cotton 47 to clean the dustproof plate. The connecting spring 50 will also continuously generate push and pull force to ensure that the matching block 46 can move back and forth normally.

[0048] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.

9. A monitoring method using a BeiDou monitoring terminal according to any one of claims 1-8, characterized in that: Includes the following steps: Step 1: First, install the installation box at the designated monitoring location. Electrically connect the controller to the external control terminal. After installation, activate the temperature sensor through the controller to monitor the internal temperature of the installation box in real time. Step 2: Open the closed door and start the monitoring terminal. After the monitoring terminal is started, connect the external line to the monitoring terminal through the opening. Step 3: After the monitoring terminal body is started and connected to the external line, the GNSS module inside the monitoring terminal body receives satellite signals from Beidou, GPS and GLONASS. After the monitoring terminal body is initialized, it will monitor the location in real time and transmit the location signal to the external control terminal in real time through the signal output module inside the monitoring terminal body. In this way, when the location of the monitored location is displaced, the displacement signal can be transmitted to the external control terminal in a timely manner. Step 4: The staff pulls the two ropes by hand, and the two enclosed boxes pop out of the installation box in part. In this way, the four dust filter plates set on the left and right sides can ensure normal ventilation inside the installation box and prevent external dust from entering the installation box and adhering to the monitoring terminal body. Step 5: When the temperature sensor detects that the internal temperature of the installation box is too high, it will send a signal to the controller through the signal output terminal. The controller will automatically control the motor, the refrigeration compressor and the two fans to start. After the two fans start, the air is directly cooled through the condenser pipe and then applied to the detection terminal body to achieve cooling. The motor output shaft drives the rotating shaft to rotate back and forth to increase the air blowing area of ​​the fan and increase the cooling effect, effectively preventing the detection terminal body from working in a high-temperature environment and affecting its service life.
