Description

Technical Field

[0001] The present invention relates to the technical field of dam monitoring station communication, and in particular to an integrated dam monitoring station communication system and method for dam deformation monitoring. Background Art

[0002] Dam shape monitoring for large hydropower projects is a critical engineering monitoring program designed to ensure the structural safety and performance of the dam. The goal is to promptly detect deformation, displacement, cracks, or other structural issues, allowing for appropriate maintenance and repair measures.

[0003] Dam monitoring stations are usually used to monitor the dam's structural deformation, stress, seepage, environment and other factors; when the monitoring data is abnormal, the monitoring station can issue an early warning in time, providing time for emergency measures to be taken to prevent the occurrence or expansion of accidents.

[0004] Dam monitoring stations are usually set up near the dam monitoring points. Multiple dam monitoring stations constitute the dam shape monitoring network. The dam monitoring stations need to transmit monitoring data to the computer in the control center in real time.

[0005] Under normal circumstances, communication at dam monitoring stations is generally achieved based on wired or wireless communication networks. However, when geological displacement occurs in the dam area, or even geological disasters such as earthquakes and landslides, it is difficult for the communication network to provide stable communication transmission.

[0006] Therefore, developing a communication network suitable for dam monitoring stations that can provide stable communication transmission in the event of geological disasters is a technical problem that needs to be solved urgently. Summary of the Invention

[0007] In order to solve the above-mentioned technical problem of stable communication of dam monitoring stations, the present invention provides an integrated dam monitoring station communication system and method for dam deformation monitoring. The following technical solutions are adopted:

[0008] An integrated dam monitoring station communication system for dam deformation monitoring includes a fiber optic cable communication unit, a wireless communication unit, an emergency communication unit, and a chip-based communication controller. The fiber optic cable communication unit includes multiple fiber optic converters and multiple fiber optic repeaters. The multiple fiber optic converters and multiple fiber optic repeaters are respectively installed at multiple dam monitoring stations. The data output end of the dam monitoring station is communicatively connected to the data input end of the fiber optic converter, and the data output end of the fiber optic converter is communicatively connected to the data input end of the fiber optic repeater. The multiple fiber optic repeaters are respectively communicatively connected to a control center server via fiber optic cables, and the multiple fiber optic repeaters are interconnected through a fiber optic cable self-organizing network communication.

[0009] The wireless communication unit realizes wireless networking based on multiple wireless bridge routers. The data input terminals of the multiple wireless bridge routers are respectively connected to the data output terminals of the dam monitoring station. The data output terminal of the wireless bridge router closest to the control center server is connected to the control center server via a communication cable.

[0010] The emergency communication unit includes multiple monitoring data black box components and at least one emergency communication aircraft. The monitoring data black box component is installed in an area within ten meters two meters away from the dam monitoring station. The data input end of the monitoring data black box component is directly connected to the data output end of the dam monitoring station through a communication cable. The monitoring data black box component is provided with an emergency radio frequency transmitter. When it is determined that a communication failure occurs, the emergency radio frequency transmitter starts to wirelessly broadcast the monitoring data stored in the monitoring data black box component to the upper space. The communication controller is connected to the control center server. When the communication controller determines that the control center server cannot communicate with one or more dam monitoring stations through the optical fiber cable communication unit or the wireless communication unit, it controls the emergency communication aircraft to fly to the area above the dam monitoring station where communication is impossible. The emergency communication aircraft and the emergency radio frequency transmitter wirelessly communicate and exchange monitoring data.

[0011] By adopting the above technical solution, reliable communication is achieved in three modes: normal communication mode, wireless communication mode and emergency communication mode. Under normal conditions, the optical fiber converter, multiple optical fiber repeaters, communication cables and other directly connected communication hardware are generally in normal conditions, which can stably and efficiently realize the normal communication between the monitoring data of the dam monitoring station and the control center server. However, when the local communication line fails or other communication hardware fails, the multiple wireless bridge routers of the wireless communication unit can realize wireless communication. The control center server can also distinguish whether the source of the monitoring data is wired or wireless. The location data of the dam monitoring station is fixed. When wireless communication fails, the staff should promptly repair it to restore the normal communication mode.

[0012] When extreme situations such as geological disasters occur in the dam area, such as earthquakes and landslides, it is very likely that both the normal communication mode and the wireless communication mode will be physically damaged and fail. At this time, the data monitored by the dam monitoring station is exactly the most critical. At this time, the emergency communication mode is adopted to control the emergency communication aircraft to fly above the dam monitoring station that cannot communicate. The monitoring data sent by the emergency RF transmitter of the monitoring data black box component can be wirelessly collected at close range, thereby avoiding the loss of the most important monitoring data of the dam monitoring station in extreme situations and ensuring the communication needs of the dam monitoring station in extreme situations.

[0013] Optionally, the monitoring data black box assembly includes a protective box, a black box support seat, a data storage black box, an emergency radio frequency transmitter, a chip-based emergency radio frequency controller and a hard communication cable. The protective box is installed on the ground in a flat area within ten meters two meters away from the dam monitoring station. The bottom of the black box support seat is installed on the bottom of the protective box. The bottom of the data storage black box is clamped on the top of the black box support seat. The emergency radio frequency transmitter is installed on the top of the data storage black box and is communicatively connected to the data output end of the data storage black box. The data storage black box and the emergency radio frequency controller are respectively communicatively connected to the data output port of the dam monitoring station through hard communication cables. The data storage black box stores the monitoring data of the dam monitoring station. The emergency radio frequency controller determines whether a communication failure occurs based on whether the dam monitoring station receives a transmission receipt. When it is determined that a communication failure occurs, the emergency radio frequency controller controls the emergency radio frequency transmitter to start wireless broadcasting of the monitoring data stored in the data storage black box to the upper space.

[0014] Optionally, the protective box is made of LCP plastic.

[0015] By adopting the above technical solution, the monitoring data black box assembly adopts two layers of protection. The protective box is made of LCP plastic. LCP plastic has good strength and will not isolate the wireless communication signal. It provides good outer protection and installation space for the data storage black box and will not affect the wireless signal of the emergency RF controller. The emergency RF transmitter is actually an RF transmitting antenna, which can wirelessly send the monitoring data stored in the data storage black box to the space above. The emergency RF controller is a data analysis chip that can collect data packets and sending receipts sent by the dam monitoring station. If the sending receipt is not received within the set time of sending the data, it can be determined that a communication failure has occurred.

[0016] Optionally, the monitoring data black box assembly also includes an automatic water injection device, which includes a gyroscope, a water injection control switch based on a single-chip microcomputer, a water tank 9 and a micro water injection pump. The water tank 9 is arranged on one side of the protective box, and the gyroscope is installed in the protective box to monitor the posture of the protective box. The water inlet and outlet of the micro water injection pump are respectively connected to the water outlet of the water tank 9 and the water inlet of the protective box through pipes. The water injection control switch is communicated with the gyroscope. When it is determined that the inclination angle of the protective box is greater than the set angle threshold, the water injection control switch controls the micro water injection pump to start injecting water into the protective box. The data storage black box is made of low-density material. When water is injected into the protective box, the data storage black box floats in the water, and the emergency radio frequency transmitter remains above the data storage black box.

[0017] By adopting the above technical solution, when extreme situations occur, the position of the protective box is likely to change significantly, or even flip over. At this time, the data storage black box is floated inside the protective box by controlling the action of the micro water injection pump to inject water into the protective box. Firstly, it plays a buffering role to prevent the data storage black box from suffering excessive physical collisions. Secondly, through the structural design of the center of gravity, the emergency radio frequency transmitter can be kept above the data storage black box, thereby ensuring that the emergency radio frequency transmitter can send data in an emergency.

[0018] Optionally, the emergency communication aircraft includes a drone and an emergency radio frequency receiver, the communication controller controls the flight movement of the drone, the emergency radio frequency receiver is mounted on the bottom of the drone, and the emergency radio frequency receiver is used to receive wireless data sent by the emergency radio frequency transmitter.

[0019] Optionally, the emergency communication aircraft further includes an emergency data storage device, which is communicatively connected to a data output terminal of the emergency radio frequency receiver.

[0020] By adopting the above technical solution, the drone can efficiently provide emergency communication support to a single dam monitoring station with a communication failure. It can also provide emergency communication support to multiple dam monitoring stations with communication failures through patrol inspections. The emergency RF receiver receives the monitoring data packets sent by the emergency RF transmitter and stores them in the emergency data storage device. When the drone lands, this part of the monitoring data can be copied by manual data collection and then imported into the control center server.

[0021] Optionally, the communication controller includes a memory, a data analysis chip and a flight control center. The memory is communicatively connected to the control center server to collect communication interaction data of the control center server. The data analysis chip analyzes the communication interaction data and analyzes the communication status between the control center server and multiple dam monitoring stations respectively. When it is determined that the control center server cannot communicate with one of the dam monitoring stations or multiple dam monitoring stations, the judgment result and the location data of the dam monitoring station that cannot communicate are interacted with the flight control center. The flight control center controls the UAV to fly to the area above the dam monitoring station that cannot communicate, and the emergency RF receiver and the emergency RF transmitter wirelessly communicate and interact with the monitoring data.

[0022] By adopting the above technical solution, the data analysis chip mainly determines whether there is a communication failure based on whether the control center server receives the monitoring data packet from the dam monitoring station at the set time. If a communication failure is determined to occur, the dam monitoring station number and the location data corresponding to the number are obtained. The flight control center then generates a control signal based on the location data to control the drone to fly to the area above the dam monitoring station where communication is impossible, thereby realizing automatic intervention in emergency communication.

[0023] The integrated dam monitoring station communication method for dam deformation monitoring adopts an integrated dam monitoring station communication system to realize the monitoring data communication between multiple dam monitoring stations and the control center server, including the following three communication modes:

[0024] In normal communication mode, the monitoring data of the dam monitoring station is sent to the control center server through the optical fiber converter and optical fiber repeater at set time intervals. The dam monitoring station determines whether there is a wired communication failure in the monitoring data based on whether the transmission receipt is received within the set receipt time after the transmission time;

[0025] Wireless communication mode: when the dam monitoring station determines that a wired communication failure has occurred, the dam monitoring station communicates wirelessly through the wireless communication unit, and realizes wireless interactive monitoring data with the control center server based on the wireless communication mode. If the dam monitoring station still does not receive a transmission receipt, it is determined that a communication failure has occurred;

[0026] In emergency communication mode, when a communication failure is detected, the emergency radio frequency transmitter starts to wirelessly broadcast the monitoring data stored in the monitoring data black box component to the space above. At the same time, when the communication controller determines that the control center server cannot communicate with one or more dam monitoring stations through the optical fiber cable communication unit or the wireless communication unit, it controls the emergency communication aircraft to fly to the area above the dam monitoring station where communication is impossible, and the emergency communication aircraft and the emergency radio frequency transmitter wirelessly communicate and exchange monitoring data.

[0027] In emergency communication mode, if the microcontroller of the water injection control switch determines that the tilt angle of the protective box is greater than the set angle threshold based on the data interacting with the gyroscope, the water injection control switch controls the micro water injection pump to start injecting water into the protective box.

[0028] In summary, the present invention includes at least one of the following beneficial technical effects:

[0029] The present invention can provide an integrated dam monitoring station communication system and method for dam deformation monitoring, which adopts three modes: normal communication mode, wireless communication mode and emergency communication mode to achieve reliable communication. Under normal conditions, the optical fiber converter, multiple optical fiber repeaters, communication cables and other hardware for direct communication are generally in normal conditions, which can stably and efficiently achieve normal communication between the monitoring data of the dam monitoring station and the control center server. However, if the local communication line fails or other communication hardware fails, the multiple wireless bridges of the wireless communication unit can achieve wireless communication.

[0030] When extreme situations such as geological disasters occur in the dam area, the emergency communication mode is adopted to control the emergency communication aircraft to fly above the dam monitoring station where communication is impossible. The monitoring data sent by the emergency RF transmitter of the monitoring data black box component can be collected wirelessly at close range, thereby avoiding the loss of the most important monitoring data of the dam monitoring station in extreme situations and ensuring the communication needs of the dam monitoring station in extreme situations.

DETAILED DESCRIPTION

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The embodiments of the present invention disclose an integrated dam monitoring station communication system and method for dam deformation monitoring.

[0037] Reference Figure 1 - Figure 3Embodiment 1: An integrated dam monitoring station communication system for dam deformation monitoring includes a fiber optic cable communication unit, a wireless communication unit, an emergency communication unit, and a chip-based communication controller. The fiber optic cable communication unit includes a plurality of fiber optic converters 11 and a plurality of fiber optic repeaters 12. The plurality of fiber optic converters 11 and the plurality of fiber optic repeaters 12 are respectively installed at a plurality of dam monitoring stations 100. The data output end of the dam monitoring station 100 is communicatively connected to the data input end of the fiber optic converter 11. The data output end of the fiber optic converter 11 is communicatively connected to the data input end of the fiber optic repeater 12. The plurality of fiber optic repeaters 12 are communicatively connected to a control center server 101 via fiber optic cables, and the plurality of fiber optic repeaters 12 are interconnected via a fiber optic cable self-organizing network.

[0038] The wireless communication unit realizes wireless networking based on multiple wireless bridge routers 21. The data input terminals of the multiple wireless bridge routers 21 are respectively connected to the data output terminals of the dam monitoring station 100. The data output terminal of the wireless bridge router 21 that is physically closest to the control center server 101 is connected to the control center server 101 via a communication cable.

[0039] The emergency communication unit includes multiple monitoring data black box components 31 and at least one emergency communication aircraft 32. The monitoring data black box component 31 is installed in an area within ten meters of two meters away from the dam monitoring station 100. The data input end of the monitoring data black box component 31 is directly connected to the data output end of the dam monitoring station 100 through a communication cable. The monitoring data black box component 31 is provided with an emergency radio frequency transmitter 314. When a communication failure is determined to occur, the emergency radio frequency transmitter 314 starts to wirelessly broadcast the monitoring data stored in the monitoring data black box component 31 to the upper space. The communication controller is communicatively connected to the control center server 101. When the communication controller determines that the control center server 101 cannot communicate with one or more dam monitoring stations 100 through the optical fiber cable communication unit or the wireless communication unit, it controls the emergency communication aircraft 32 to fly to the area above the dam monitoring station 100 where communication is impossible, and the emergency communication aircraft 32 wirelessly exchanges monitoring data with the emergency radio frequency transmitter 314.

[0040] Reliable communication is achieved by adopting three modes: normal communication mode, wireless communication mode and emergency communication mode. Under normal conditions, the optical fiber converter 11, multiple optical fiber repeaters 12, communication cables and other directly connected communication hardware are generally in normal conditions, which can stably and efficiently realize normal communication between the monitoring data of the dam monitoring station 100 and the control center server 101. However, when the local communication line fails or other communication hardware fails, the multiple wireless bridge routers 21 of the wireless communication unit can realize wireless communication. The control center server 101 can also distinguish whether the source of the monitoring data is wired or wireless. The location data of the dam monitoring station 100 is fixed. When wireless communication fails, the staff should promptly carry out maintenance to restore the normal communication mode.

[0041] When extreme situations such as geological disasters occur in the dam area, such as earthquakes, landslides, etc., it is very likely that both the normal communication mode and the wireless communication mode will be physically damaged and fail. At this time, the data monitored by the dam monitoring station 100 is exactly the most critical. At this time, the emergency communication mode is adopted to control the emergency communication aircraft 32 to fly above the dam monitoring station 100 that cannot communicate. The monitoring data sent by the emergency RF transmitter 314 of the monitoring data black box component 31 can be collected wirelessly at close range, thereby avoiding the loss of the most important monitoring data of the dam monitoring station 100 in extreme situations and ensuring the communication needs of the dam monitoring station 100 in extreme situations.

[0042] Example 2, the monitoring data black box assembly 31 includes a protective box 311, a black box supporting seat 312, a data storage black box 313, an emergency radio frequency transmitter 314, a chip-based emergency radio frequency controller 315 and a hard communication cable 316. The protective box 311 is installed under the ground in a flat area within ten meters of 100 meters away from the dam monitoring station. The bottom of the black box supporting seat 312 is installed at the bottom of the protective box 311. The bottom of the data storage black box 313 is clamped on the top of the black box supporting seat 312. The emergency radio frequency transmitter 314 is installed on the top of the data storage black box 313 and is connected to the emergency radio frequency transmitter 314. The data output end of the data storage black box 313 is communicatively connected. The data storage black box 313 and the emergency radio frequency controller 315 are communicatively connected to the data output port of the dam monitoring station 100 through a hard communication cable 316 respectively. The data storage black box 313 stores the monitoring data of the dam monitoring station 100. The emergency radio frequency controller 315 determines whether a communication failure occurs based on whether the dam monitoring station 100 receives a transmission receipt. When it is determined that a communication failure occurs, the emergency radio frequency controller 315 controls the emergency radio frequency transmitter 314 to start wirelessly broadcasting the monitoring data stored in the data storage black box 313 to the upper space.

[0043] In embodiment 3, the protective box 311 is made of LCP plastic.

[0044] The monitoring data black box assembly 31 adopts two layers of protection. The protective box 311 is made of LCP plastic. LCP plastic has good strength and will not isolate wireless communication signals. It provides good outer protection and installation space for the data storage black box 313 and will not affect the wireless signal of the emergency radio frequency controller 315. The emergency radio frequency transmitter 314 is actually a radio frequency transmitting antenna, which can wirelessly send the monitoring data stored in the data storage black box 313 to the upper space. The emergency radio frequency controller 315 is a data analysis chip that can collect data packets and sending receipts sent by the dam monitoring station 100. If the sending receipt is not received within the set time for sending data, it can be determined that a communication failure has occurred.

[0045] In embodiment 4, the monitoring data black box assembly 31 also includes an automatic water injection device, which includes a gyroscope, a water injection control switch based on a single-chip microcomputer, a water tank 319 and a micro water injection pump 317. The water tank 319 is arranged on one side of the protective box 311, and the gyroscope is installed in the protective box 311 for monitoring the posture of the protective box 311. The water inlet and outlet of the micro water injection pump 317 are connected to the water outlet of the water tank 319 and the water inlet of the protective box 311 through pipes respectively. The water injection control switch is communicated with the gyroscope. When it is determined that the inclination angle of the protective box 311 is greater than the set angle threshold, the water injection control switch controls the micro water injection pump 317 to start injecting water into the protective box 311. The data storage black box 313 is made of low-density material. When the protective box 311 is filled with water, the data storage black box 313 floats in the water, and the emergency radio frequency transmitter 314 remains above the data storage black box 313.

[0046] When an extreme situation occurs, it is very likely that the position of the protective box 311 will change significantly, or even flip over. At this time, the data storage black box 313 is floated inside the protective box 311 by controlling the micro water injection pump 317 to inject water into the protective box 311. Firstly, it plays a buffering role to prevent the data storage black box 313 from suffering excessive physical collisions. Secondly, through the structural design of the center of gravity, the emergency RF transmitter 314 can be kept above the data storage black box 313, thereby ensuring that the emergency RF transmitter 314 can send data in an emergency.

[0047] In Example 5, the emergency communication aircraft 32 includes a drone 321 and an emergency RF receiver 322. The communication controller controls the flight movement of the drone 321. The emergency RF receiver 322 is mounted on the bottom of the drone 321. The emergency RF receiver 322 is used to receive wireless data sent by the emergency RF transmitter 314.

[0048] In Example 6, the emergency communication aircraft 32 further includes an emergency data storage 323 , which is communicatively connected to a data output terminal of the emergency radio frequency receiver 322 .

[0049] The drone 321 can efficiently provide emergency communication support to a single dam monitoring station 100 with a communication failure, and can also provide emergency communication support to multiple dam monitoring stations 100 with communication failures by patrolling. The emergency RF receiver 322 receives the monitoring data packet sent by the emergency RF transmitter 314 and stores it in the emergency data storage 323. When the drone 321 lands, this part of the monitoring data can be copied by manually collecting data and then imported into the control center server 101.

[0050] In embodiment 7, the communication controller includes a memory 41, a data analysis chip 42 and a flight control center 43. The memory 41 is communicatively connected to the control center server 101 to collect communication interaction data of the control center server 101. The data analysis chip 42 analyzes the communication interaction data and analyzes the communication status between the control center server 101 and multiple dam monitoring stations 100 respectively. When it is determined that the control center server 101 cannot communicate with one of the dam monitoring stations 100 or multiple dam monitoring stations 100, the judgment result and the location data of the dam monitoring station 100 that cannot communicate are exchanged with the flight control center 43. The flight control center 43 controls the drone 321 to fly to the area above the dam monitoring station 100 that cannot communicate. The emergency radio frequency receiver 322 and the emergency radio frequency transmitter 314 wirelessly communicate and exchange monitoring data.

[0051] The data analysis chip 42 mainly determines whether a communication failure occurs based on whether the control center server 101 receives the monitoring data packet from the dam monitoring station 100 at a set time. If a communication failure is determined to occur, the number of the dam monitoring station 100 with the communication failure and the location data corresponding to the number are obtained. The flight control center 43 then generates a control signal based on the location data to control the drone 321 to fly to the area above the dam monitoring station 100 where communication is impossible, thereby realizing automatic intervention in emergency communication.

[0052] Example 8, an integrated dam monitoring station communication method for dam deformation monitoring, uses an integrated dam monitoring station communication system to implement monitoring data communication between multiple dam monitoring stations 100 and a control center server 101, including the following three communication modes:

[0053] In normal communication mode, the monitoring data of the dam monitoring station 100 is sent to the control center server 101 through the optical fiber converter 11 and the optical fiber repeater 12 at every set time interval. The dam monitoring station 100 determines whether there is a wired communication failure in the monitoring data based on whether a transmission receipt is received at a set receipt time after the transmission time;

[0054] Wireless communication mode: when the dam monitoring station 100 determines that a wired communication failure occurs, the dam monitoring station 100 performs wireless communication through the wireless communication unit, and realizes wireless interaction of monitoring data with the control center server 101 based on the wireless communication mode. If the dam monitoring station 100 still does not receive a transmission receipt, it is determined that a communication failure occurs;

[0055] In emergency communication mode, when a communication failure is detected, the emergency radio frequency transmitter 314 starts to wirelessly broadcast the monitoring data stored in the monitoring data black box component 31 to the upper space. At the same time, when the communication controller determines that the control center server 101 cannot communicate with one or more dam monitoring stations 100 through the optical fiber cable communication unit or the wireless communication unit, it controls the emergency communication aircraft 32 to fly to the area above the dam monitoring station 100 that cannot communicate, and the emergency communication aircraft 32 wirelessly communicates with the emergency radio frequency transmitter 314 to exchange monitoring data.

[0056] Example 9: In emergency communication mode, if the microcontroller of the water injection control switch determines that the tilt angle of the protective box 311 is greater than the set angle threshold based on the data interacting with the gyroscope, the water injection control switch controls the micro water injection pump 317 to start injecting water into the protective box 311.

[0057] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
