Description

Technical Field

[0001] The present invention relates to the field of navigation safety technology, and in particular to a safety monitoring system and method based on a pressure water level gauge. Background Art

[0002] The deformation observation of navigation structures is an important part of dam safety monitoring. It mainly monitors the horizontal displacement of the ship lock wall through the tensioning line instrument and the vertical coordinate instrument, monitors the vertical displacement of the ship lock wall through the static level, regularly monitors the horizontal displacement of the ship lock wall through the measuring robot, and monitors the horizontal displacement of the ship lift through the vertical coordinate instrument. At the same time, the monitoring data of these instruments change with the changes in water level data. The deformation observation of navigation structures requires observing the deformation of navigation structures under different water level conditions.

[0003] To this end, a technical solution has been proposed to install an ultrasonic water level meter at the mouth of the water level measuring pipe of the ship lock to obtain water level data. However, in actual application, as time goes by, spider webs appear at the mouth of the water level measuring pipe of the ship lock, and floating objects and impurities appear on the water surface of the ship lock; these factors cause the ultrasonic wave to hit impurities such as spider webs or floating objects, resulting in deviations between the acquired water level data and the actual water level data, which affects the subsequent monitoring and judgment of the entire system. At the same time, the water level data obtained by the ultrasonic water level meter needs to be obtained through amplification, filtering, analog-to-digital conversion and DSP processing. During the amplification and filtering process, factors such as temperature, air humidity, air pressure, airflow, and different gas media will affect the speed of sound wave propagation, thereby reducing the measurement accuracy.

[0004] In addition, atmospheric temperature and air pressure also have a certain impact on the monitoring accuracy of tension line instruments, plumb line coordinate instruments, static levels, and measuring robot monitoring equipment. Therefore, meteorological corrections need to be made to the monitoring equipment before monitoring.

[0005] In this regard, existing technical means mainly use meteorological monitoring sensors to obtain temperature and air pressure parameters, perform meteorological correction and differential calculation. However, meteorological correction parameters need to be obtained through meteorological monitoring sensors, which increases monitoring costs and equipment maintenance time. Summary of the invention

[0012] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0013] Please refer to Figures 1 to 3 , a safety monitoring system based on a pressure water level gauge, comprising a monitoring main controller 1, a ship lock deformation monitoring device and a water level monitoring component; The water level monitoring assembly includes a pressure water level gauge 2 and a ship lock water level measuring pipe 3; The monitoring main controller 1 is respectively connected to the ship lock deformation monitoring device and the pressure water level gauge 2 for communication, the ship lock deformation monitoring device is used to be arranged on the target ship lock chamber 4, and the ship lock water level measuring tube 3 is used to be arranged in the target ship lock chamber 4; The pressure water level gauge 2 is arranged at the bottom of the ship lock water level measuring pipe 3, and an air guide pipe is arranged on the pressure water level gauge 2, one end of the air guide pipe is connected with the sensor inner cavity of the pressure water level gauge 2, and the other end of the air guide pipe is used to connect with the atmosphere above the water surface, and the pressure water level gauge 2 is used to send atmospheric temperature data, atmospheric pressure data and first water level elevation data to the monitoring main controller 1; The monitoring main controller 1 is used to perform meteorological correction on the first deformation monitoring data and the first water level elevation data of the ship lock deformation monitoring device according to the atmospheric temperature data and the atmospheric pressure data to obtain second deformation monitoring data and second water level elevation data, and analyze the deformation condition of the target ship lock chamber 4 under different water level conditions according to the second deformation monitoring data and the second water level elevation data. From the above description, it can be seen that the beneficial effects of the present invention are: a water level monitoring component mainly based on a pressure water level gauge 2 is adopted, an air duct is set and combined with the air pressure and temperature measurement functions of the pressure water level gauge 2, so as to measure atmospheric temperature data, atmospheric pressure data and first water level elevation data, reduce equipment cost and equipment maintenance time, and eliminate the influence of floating objects and impurities on the water surface of the lock on water level measurement, and use atmospheric temperature data and atmospheric pressure data to simultaneously correct water level elevation data and deformation monitoring data, provide a more stable and accurate water level monitoring function, accurately observe the deformation status of navigation buildings, and ensure navigation safety.

[0014] Furthermore, the pressure water level gauge 2 includes a protective housing, a controller, a pressure sensor and a transmission cable; The controller and the pressure sensor are both located in the protective housing, a water-permeable component corresponding to the pressure sensor is provided on the protective housing, and the controller is connected to the pressure sensor; The controller is communicatively connected with the monitoring main controller 1 via the transmission cable.

[0015] From the above description, it can be seen that the pressure water level gauge 2 is composed of a protective shell, a controller and a pressure sensor, and uses the induced water pressure to monitor the water level changes in real time and reports the data using a transmission cable.

[0016] Furthermore, the ship lock deformation monitoring device comprises a plumb line assembly 5 and a tension line assembly 6; The plumb line assembly 5 and the tension line assembly 6 are used to be arranged on the target ship lock chamber 4 .

[0017] From the above description, it can be seen that the ship lock deformation monitoring device includes a plumb line assembly 5 and a tension line assembly 6. The plumb line assembly 5 and the tension line assembly 6 are used to assist instruments such as a tension line meter and a plumb line coordinate meter in measuring work to improve monitoring accuracy.

[0018] Furthermore, the ship lock deformation monitoring device also includes a total station 7, a circular prism group 8, a measuring point measuring pier 9 and a measuring station measuring pier 10; The circular prism groups 8 are arranged one by one on the measuring point measuring piers 9, and all the measuring point measuring piers 9 are used to be distributed and arranged on the target ship lock chamber 4, and the total station 7 is arranged on the measuring station measuring piers 10; The main controller is connected to the total station 7 and the circular prism group 8 for communication respectively.

[0019] From the above description, it can be known that a measurement method in which a total station 7 and a plurality of circular prism groups 8 cooperate with each other can also be adopted to achieve multi-angle and all-round measurement.

[0020] Furthermore, there are more than two water level monitoring components and they correspond one-to-one to the target ship lock chambers 4 .

[0021] From the above description, it can be seen that, especially for the application scenario of the three-level ship lock at the water mouth, centralized supervision of multiple levels of ship locks can be achieved to comprehensively and efficiently ensure navigation safety.

[0022] Please refer to Figure 4 A safety monitoring method based on a pressure water level gauge is applied to the above-mentioned safety monitoring system based on a pressure water level gauge, comprising the following steps: S1, obtaining atmospheric temperature data, atmospheric pressure data and first water level data sent by the pressure water level gauge 2 of the target ship lock chamber 4, performing meteorological correction on the first water level data according to the atmospheric temperature data and the atmospheric pressure data, and obtaining second water level data; S2, obtaining first deformation monitoring data sent by the ship lock deformation monitoring device, and performing meteorological correction on the first deformation monitoring data according to the atmospheric temperature data and the atmospheric pressure data to obtain second deformation monitoring data; S3. Analyze the deformation status of the target ship lock chamber 4 under different water level conditions according to the second deformation monitoring data and the second water level elevation data.

[0023] From the above description, it can be seen that the beneficial effects of the present invention are: a water level monitoring component mainly based on a pressure water level gauge 2 is adopted, an air duct is set and combined with the air pressure and temperature measurement functions of the pressure water level gauge 2, so as to measure atmospheric temperature data, atmospheric pressure data and first water level elevation data, reduce equipment cost and equipment maintenance time, and eliminate the influence of floating objects and impurities on the water surface of the lock on water level measurement, and use atmospheric temperature data and atmospheric pressure data to simultaneously correct water level elevation data and deformation monitoring data, provide a more stable and accurate water level monitoring function, accurately observe the deformation status of navigation buildings, and ensure navigation safety.

[0024] Furthermore, the step S1 further includes: Determine whether the second water level elevation data is greater than the installation elevation of the pressure water level gauge 2. If so, correct the atmospheric temperature data and the atmospheric pressure data according to the second water level elevation data and the installation elevation, and use the corrected atmospheric temperature data and the atmospheric pressure data to execute step S2; otherwise, directly execute step S2.

[0025] From the above description, it can be seen that when using atmospheric temperature data and atmospheric pressure data to correct deformation monitoring data, the errors between the atmospheric temperature and pressure measured underwater and the actual atmospheric temperature and pressure are fully considered, and the atmospheric temperature data and atmospheric pressure data are corrected to ensure the accuracy of subsequent monitoring and analysis.

[0026] Furthermore, before step S1, the following steps are also included: S0. Setting the measurement priority of each target ship lock chamber 4, and executing step S1 for each target ship lock chamber 4 according to the measurement priority.

[0027] It can be seen from the above description that when facing multiple target lock chambers 4, a priority processing method is adopted to monitor each target lock chamber 4 in order to improve the convenience of operation and maintenance management.

[0028] Furthermore, the step S1 further includes: Determine whether the second water level elevation data is greater than or equal to a preset water level threshold corresponding to the target ship lock chamber 4, if so, execute step S2, otherwise re-execute step S1.

[0029] From the above description, it can be seen that a preset water level threshold is set to decide whether to perform a deformation monitoring system, so as to meet the monitoring needs of deformation under different water level conditions, while reducing some unnecessary monitoring workload of the device and alleviating data processing pressure.

[0030] Furthermore, the step S3 is specifically as follows: A deformation statistics table and a process line diagram of the target ship lock chamber 4 under different water level conditions are generated according to the second deformation monitoring data and the second water level elevation data.

[0031] From the above description, it can be seen that when analyzing, a deformation statistics table and a process line diagram are used in combination to facilitate a more intuitive and clear understanding of the deformation condition of the ship lock.
