[0029] Example 1

[0030] like Figures 1 to 3As shown, a gate opening monitoring device described in an embodiment of the utility model includes a gate frame 101, a gate plate 102 is movably arranged in the gate frame 101, a first pulley 103 and a second pulley 104 are arranged on both sides of the gate plate 102, the gate plate 102 is slidably connected to the gate frame 101 through the first pulley 103 and the second pulley 104, the first pulley 103 is located at the bottom end of the gate plate 102, the second pulley 104 is located in the middle section of the gate plate 102, the first pulley 103 slides in the vertical direction, and the second pulley 104 slides in the horizontal direction or the vertical direction; at least one laser monitor 2 is arranged on the gate frame 101, the laser monitor 2 is used to monitor the position of the gate plate 102, the laser monitor 2 is connected to the server 3 for communication, and the server 3 is used to collect data of the laser monitor 2 to calculate the opening of the gate 1.

[0031] In this embodiment, when the gate 1 is opened, the gate plate 102 slides upward first, at which time the first pulley 103 and the second pulley 104 both slide upward, and the opening of the gate 1 gradually increases. Then the gate plate 102 begins to flip, the first pulley 103 continues to slide upward, the second pulley 104 slides horizontally, and the opening of the gate 1 continues to increase. Until the gate plate 102 is horizontal, the gate 1 reaches the maximum opening. The laser monitor 2 regularly measures the position of the gate 1 and sends the measurement data to the server 3 via a wired network or a wireless network. The server 3 calculates the opening of the gate 1 based on the measurement data. If the laser monitor 2 measures the flip angle of the gate 1, the opening value can be calculated by trigonometric conversion. The mechanism that drives the gate plate 102 to move can be a winch, a hydraulic cylinder, a screw hoist, etc.

[0032] The measurement method adopts a group of measurements every 5 seconds, collects a large amount of data and then processes the data according to the installation characteristics of the site, and finally obtains the distance value that best meets the actual situation. By presetting the situation information of the gate 1 on the server 3, the server 3 and the laser monitor 2 interact to perform measurement and judgment to solve the problem of differences on the site. The data collected on site mainly include: the position of gate 1, at which time of the day there will be strong sunlight when gate 1 is opened and closed, at which position on the measurement path there will be interference from the winch steel cable, etc. After uploading these data to the server 3, the server 3 will control the laser monitor 2 according to these on-site data. In the process of measurement, the laser monitor 2 will perform repeated measurements at the corresponding time point or the corresponding position, and judge the real data according to the continuity of the value, and judge whether different data in multiple measurements are interference data or real data. For example, at a location with steel cable interference, after multiple measurements, it is found that there are other values ​​besides the steel cable position value. The real value is judged according to the continuity of the value. It is very likely that these few other values ​​are the real position of gate 1.

[0033] When gate 1 is opened or closed to a certain position, laser monitor 2 will detect that the position of gate 1 has changed from the previous position. The position change at this time may also be caused by some interference factors. The measurement value of laser monitor 2 has changed, and it is unclear whether the actual position has changed. At this time, it will trigger a query to remote server 3 whether to perform detailed measurement again. Server 3 will preset information based on the characteristics of each gate 1 and reply to laser monitor 2 whether to measure. If necessary, detailed measurement will be carried out, and data processing will be carried out after the measurement is completed, and finally the current position information of gate 1 will be returned.

[0034] The laser monitor 2 is a ruby ​​laser, a neodymium glass laser, a carbon dioxide laser or a gallium arsenide laser. In this embodiment, the options for the laser monitor 2 include ruby ​​lasers, neodymium glass lasers, carbon dioxide lasers or gallium arsenide lasers. These lasers have different characteristics and working principles and can be selected according to specific needs. Ruby lasers have higher power and stability, and are suitable for long-distance measurements and more complex environments. Neodymium glass lasers have higher pulse energy and shorter pulse width, and are suitable for high-speed measurements and weakly reflective targets. Carbon dioxide lasers have higher power and longer wavelengths, and are suitable for large-range measurements and non-metallic materials. Gallium arsenide lasers have smaller size and higher frequency stability, and are suitable for high-precision measurements.

[0035] In actual application, the number of laser monitors 2 can be set according to demand, and at least one is set. If multiple are set, multiple measurement values ​​can be obtained and the data can be calibrated.

[0036] like Figures 1 to 3 As shown, in a preferred embodiment, when the laser monitor 2 is provided with one, the laser monitor 2 is provided on the top plate of the gate frame 101, the laser monitor 2 is located above the gate plate 102 in a vertical state, and the light emission direction of the laser monitor 2 is coplanar with the axis movement direction of the two first pulleys 103. In this embodiment, when the laser monitor 2 monitors the position of the gate plate 102, the monitoring position will change with the movement of the gate plate 102. When the gate 1 is opened from a closed state, the gate 1 first rises vertically. During the vertical rising stage, the laser monitor 2 monitors the top of the gate 1. When the height rises to the point where the second pulley 104 starts to move horizontally, that is, the gate 1 starts to flip, the monitoring position of the laser monitor 2 gradually shifts from the top of the gate 1 to the water retaining surface of the gate 1. As the gate 1 continues to open, the position monitored by the laser monitor 2 moves from the top of the water retaining surface of the gate 1 to the bottom until the gate 1 is fully opened, at which time the gate 1 is in a horizontal state. In the whole process, the laser monitor 2 can monitor the position of the gate plate 102, and the measured value changes dynamically with the movement of the gate plate 102, thereby ensuring the continuity and accuracy of the monitoring.

[0037] Example 2

[0038] like Figure 4 and Figure 5 As shown, the difference from Example 1 is that the laser monitor 2 is rotatably set on the gate frame 101, and the height of the laser monitor 2 is not lower than the height of the gate plate 102 in the horizontal state. In this embodiment, the laser monitor 2 is driven to rotate by a driving device such as a motor. The rotating laser monitor 2 can measure the positions of multiple points of the gate plate 102. Combined with the rotation angle of the laser monitor 2, and when the monitoring positions are on the same plane, the various monitoring points are collinear. Based on this, the server 3 can calculate the rising height of the gate plate 102, that is, the opening of the gate 1 can be calculated. In addition, the rotating laser monitor 2 can measure the positions of multiple points of the gate plate 102 at the same position. The data of each point can be combined to more accurately calculate the position of the gate plate 102. Combined with the position data preset in the server 3, the opening of the gate 1 can be accurately determined. The height of the laser monitor 2 is not lower than the height of the gate plate 102 in a horizontal state, so that when the gate plate 102 is fully opened, the laser monitor 2 generally will not be immersed in the water flow, which can protect the laser monitor 2 and ensure the service life of the laser monitor 2. On the other hand, light will be refracted in water, and impurities in the water will reflect light, which will affect the measurement accuracy of the laser monitor 2. In this embodiment, the laser monitor 2 generally will not be immersed in the water flow, ensuring the accuracy of the measurement.

[0039] In practical applications, such as Figure 4 As shown, the laser monitor 2 can be rotatably arranged on the top plate of the gate frame 101. Preferably, the laser monitor 2 is located above the gate plate 102 in a vertical state. Figure 5 As shown, the laser monitor 2 is rotatably disposed on the side plate of the gate frame 101 . Preferably, the laser monitor 2 is located at one end of the horizontal gate plate 102 , and the height of the laser monitor 2 is not lower than the height of the horizontal gate plate 102 .

[0040] Example 3

[0041] like Figure 6 As shown, the difference from Example 1 is that two laser monitors 2 are provided, one of which is provided on the top plate of the gate frame 101, and the laser monitor 2 is located above the gate plate 102 in a vertical state, and the other laser monitor 2 is provided on the side plate of the gate frame 101, and the laser monitor 2 is located at one end of the gate plate 102 in a horizontal state.

[0042] In this embodiment, more data points can be obtained by setting laser monitors 2 on the top plate and side plates of the gate frame 101. Compared with a single fixed laser monitor 2, two sensors can simultaneously measure points at different positions of the gate plate 102, thereby providing more data for calculating the opening of the gate 1, which can reduce data errors and improve accuracy. The setting of multiple laser monitors 2 can correct possible interference with each other. For example, the steel cable may affect the measurement of the laser monitor 2. By comparing the data of the laser monitors 2 at different positions, abnormal values ​​can be detected and eliminated, thereby improving accuracy. When one laser monitor 2 fails or interferes, another laser monitor 2 can provide backup data. This redundant design can enhance the fault tolerance of the system and ensure that accurate measurement results can be provided even if some sensors fail.

[0043] In actual application, the two laser monitors 2 can be fixedly installed on the gate frame 101 or rotatably installed on the gate frame 101. The specific installation method is installed according to the use requirements.

[0044] Example 4

[0045] like Figure 7 As shown, the difference from Example 3 is that the laser monitor 2 can be set on the side plate of the gate frame 101, at least one laser monitor 2 is rotatably connected to the side plate, the two laser monitors 2 are in the same horizontal position, the two laser monitors 2 are respectively located at the two ends of the horizontal gate plate 102, and the height of the two laser monitors 2 is not lower than the height of the horizontal gate plate 102. Similar to the above embodiment, the two horizontally arranged laser monitors 2 can also reduce data errors and improve accuracy. Different from the above embodiment, at least one laser monitor 2 is rotatably connected to the side plate, and the rotatably arranged laser monitor 2 can monitor the rising height of the gate plate 102 during the vertical rise of the gate plate 102.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
