Description

Technical Field

[0001] This invention relates to the field of industrial measurement technology, specifically to an industrial displacement sensor and measurement system for multi-point synchronous measurement. Background Technology

[0002] In modern industrial production, such as coke oven incineration, material storage and management are crucial. To ensure production continuity and efficiency, accurate monitoring of the material state within containers is paramount. Traditional material measurement methods rely primarily on single-point measurements or manual inspection, which are not only inefficient but also fail to provide comprehensive, real-time data support. With the development of automation and sensor technologies, multi-point synchronous measurement systems are gradually becoming an industry trend. These systems, by distributing multiple sensors along the inner wall of the container, can simultaneously monitor multiple parameters of the material, such as height, density, and internal structure, thus providing the plant with more accurate and reliable material information. The advantages of multi-point synchronous measurement systems are particularly evident for large storage tanks or containers with complex shapes.

[0003] Although existing multi-point measurement systems have improved the accuracy and efficiency of material management to some extent, they still have some limitations. The sensors in existing systems usually work independently and lack an effective coordination mechanism, which increases the difficulty of data integration and affects the accuracy of the final analysis results. In addition, many systems cannot perform non-contact operation when performing density and internal structure detection, and are easily affected by environmental factors, which reduces the stability and reliability of long-term operation.

[0032] This application provides an industrial displacement sensor and measurement system for multi-point synchronous measurement. This system, by introducing a main control system and a detection system, solves the problems of independent sensor operation and lack of effective coordination mechanisms in existing technologies. The main control system is responsible for the overall management and scheduling of multiple sensor components distributed on the inner wall of the container, ensuring their synchronous collaboration and reducing the difficulty of data integration. This collaborative working mode not only improves the consistency and accuracy of data collection but also makes the final analysis results more reliable. Using various non-contact detection components, it can complete the detection of height, density, and internal structure without direct contact with the material, avoiding wear and errors caused by physical contact. Continuous calibration provides long-term stable monitoring while achieving high-precision detection results. The following provides a detailed description of this industrial displacement sensor and measurement system for multi-point synchronous measurement. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0033] This application will now be described in detail with reference to the accompanying drawings and specific embodiments. Please refer to... Figure 1-6 This embodiment provides an industrial displacement sensor for multi-point synchronous measurement, comprising: a composite sensor 1, wherein multiple composite sensors 1 are used in conjunction with each other; a vibration sensing component, disposed between two composite sensors 1, for detecting the material between the two composite sensors 1 and determining the material stacking height; a density component, disposed between two composite sensors 1, for detecting the density of the stacked material to ensure the stacking density; a laser detection component, disposed on one side of the bottom of the composite sensor 1, for detecting the top edge of the material; a sonar detection component, disposed on one side of the composite sensor 1, for detecting the cavity inside the material stack; and a mounting component, disposed on the back of the composite sensor 1, for fixing the composite sensor 1 for easy installation on the inner surface of the container.

[0034] Furthermore, the vibration sensing component includes: a detection wire 3 disposed between two composite sensors 1; an oscillation groove 301 formed at the top of the composite sensor 1, a sensing groove 303 formed at the bottom of the composite sensor 1, the top of the detection wire 3 disposed inside the sensing groove 303, and the bottom of the detection wire 3 connected to the inside of the oscillation groove 301; an oscillation motor 302 disposed inside the oscillation groove 301, one side of the oscillation motor 302 contacting the detection wires 3; and multiple contact sensors 304 disposed on the inner wall of the sensing groove 303, which contact the detection wires 3 with the contact sensors 304 on both sides when the detection wires 3 oscillate.

[0035] During use, when the material comes into contact with the detection wire 3, the vibration generated by the oscillating motor 302 is transmitted to the contact sensor 304 in the sensing groove 303. The material height is determined based on the change in contact frequency or intensity, and the material height is detected by mechanical vibration.

[0036] Furthermore, the compaction component includes: a pressure tube 2 disposed between the two composite sensors 1, with multiple telescopic sleeves 201 on the surface of the pressure tube 2, the multiple telescopic sleeves 201 communicating with the interior of the pressure tube 2; pressure cavities 202 disposed at the top and bottom of the composite sensors 1, with a pressure plate 203 slidably connected inside the pressure cavities 202; and an electric push rod 204 disposed inside the pressure cavities 202, the end of the electric push rod 204 being connected to the pressure plate 203, and a pressure sensor 205 disposed on one side of the pressure plate 203;

[0037] During use, the electric push rod 204 can push the pressure plate 203 to move. The moving pressure plate 203 can pressurize the air inside the pressure tube 2. When the air pressure increases, the pressure will push out the multiple telescopic sleeves 201 on both sides and squeeze the material on both sides through the telescopic sleeves 201. During this process, the material will also put pressure on the telescopic sleeves 201. When the telescopic sleeves 201 are pushed out, the pressure plate 203 can move. At this time, it means that the pressure applied by the electric push rod 204 to the pressure plate 203 is greater than the pressure put on the telescopic sleeves 201 by the material on both sides. At this time, the pressure sensor 205 can record the critical pressure before the pressure plate 203 moves and send it to the sensing module S211 in the main control system S1 for sensing and judgment, thereby recording the internal density.

[0038] Furthermore, the laser sensing component includes: multiple laser detectors 5 disposed on one side of the composite sensor 1. The multiple laser detectors 5 are distributed in two groups, one group is arranged in a horizontal structure and the other group is arranged in a downward inclined structure. During use, the multiple laser detectors 5 can irradiate the top surface of the material with laser and detect the return angle to determine the top height of the material. This method is used to detect the top height of the material.

[0039] Furthermore, the sonar detection assembly includes: a sonar detection platform 4 disposed on one side of the composite sensor 1, with multiple sonar transmitters 401 disposed on one side of the sonar detection platform 4; and multiple sonar receivers 402 disposed on one side of the sonar detection platform 4, with the multiple sonar receivers 402 located below the sonar transmitters 401. During use, the multiple sonar transmitters 401 emit sonar and the multiple sonar receivers 402 receive the sonar data, thereby roughly detecting the height and surface height distribution of the surface to be detected by sonar, which facilitates the judgment of the stacking status of the material.

[0040] Furthermore, the mounting assembly includes: a mounting plate 101 located on one side of the composite sensor 1, with a fixing platform 102 fitted onto one side of the mounting plate 101 for connection with the inner wall of the device to be tested, and a threaded bolt 103 connecting the fixing platform 102 and the mounting plate 101 via a threaded rotatable connection; an adsorption chamber 104 located on one side of the composite sensor 1, with an adsorption plate 106 inside the adsorption chamber 104, and an adsorption motor 105 mounted on the inner wall of the adsorption chamber 104. A threaded rod is connected to one side of the adsorption motor 105 via a drive shaft, and the threaded rod is threadedly engaged with the adsorption plate 106. During use, the location where the composite sensor 1 needs to be installed is first determined. The fixing platform 102 is nailed to the predetermined position and connected to the mounting plate 101 by threaded rotation. The threaded bolt 103 is rotated with a tool to make the fixing platform 102 and the mounting plate 101 tightly connected, while ensuring that the two are firmly attached to the inner wall of the container. After the power is turned on, the adsorption motor 105 starts to work, driving the internal threaded rod to rotate. As the threaded rod rotates, the adsorption plate 106 moves closer to the inner wall of the container along the direction of thread engagement until it makes full contact and generates sufficient adsorption force to ensure that the composite sensor 1 is stably installed. The assembly adopts a combination of mechanical fixing and magnetic adsorption, which increases the stability of the installation with double protection, and also facilitates disassembly and maintenance.

[0041] A multi-point synchronous measurement system includes: a main control system S1, which includes at least a main control terminal S101 and an analysis module S102, used to control and coordinate multiple sensors in the system as a whole, and to model and analyze the overall material quantity in the container based on the results obtained from the multiple sensors; multiple sensors, which are distributed on the inner wall of the container and are equidistantly arranged around the inner surface of the container; a detection system S2, which cooperates with the control of the main control system S1 to detect the material in the volume cavity to determine the quantity of material contained and to establish a containment model; and an inspection system S3, which inspects and judges the material quantity obtained by the detection system S2 and the main control system S1.

[0042] During use, the main control system S1 integrates control and analysis functions, which can efficiently manage and coordinate multiple sensors to ensure the consistency and accuracy of data collection. At the same time, multiple sensors are equidistantly distributed around the inner wall of the container, realizing all-round, blind-angle monitoring of the material status, improving the reliability of the system and the integrity of the data. Finally, through the analysis module S102, a material model can be automatically built based on the sensor data to assist managers in making decisions and improve work efficiency.

[0043] Furthermore, the detection system S2 is internally divided into a primary detection subsystem S210 and a secondary detection subsystem S220. The primary detection subsystem S210 uses a sensing module S211 for sensing, wherein the sensing module S211 includes at least a vibration sensing component for detecting the material filling height or filling depth. The secondary detection subsystem S220 includes a density detection module S221 and a laser detection module S222, wherein the density detection module S221 includes at least a density component for detecting the overall density, and the laser detection module S222 includes at least a laser detection component for detecting the distance between the material edge and the sensor to determine the precise stacking height of the material.

[0044] During operation, the design of the primary detection subsystem S210 and the secondary detection subsystem S220 divides the detection process into two stages: preliminary sensing followed by detailed detection. This improves detection efficiency and reduces unnecessary resource consumption. Furthermore, the density detection module S221 and the laser detection module S222 provide more detailed material characteristic information, which helps to generate a more accurate material model.

[0045] Furthermore, the inspection system S3 includes a sonar verification module S301, which includes at least a sonar detection component for detecting cavities. The sonar verification module S301 can detect cavities inside the material, ensuring the uniformity and quality of material filling and avoiding potential safety hazards. By comparing with a detailed overall model, the sonar verification module can correct any possible errors and improve the accuracy of the final model.

[0046] Furthermore, the following operational steps are included between the main control system S1 and the detection system S2:

[0047] Step S1: The main control system S1 starts and triggers the sensor through the main control terminal S101. The sensor detects the feeding depth of the material and the sensing module S211 makes a preliminary sensing judgment.

[0048] Step S2: After the depth is initially sensed by the sensing module S211, the compactness detection module S221 is activated to push and detect the material to determine the compactness of the material and obtain the actual compactness ρ.

[0049] Step S3: Further, the laser detection module S222 performs laser detection on the material from the top of the material pile to determine the material feed rate and precise height. The heights recorded by the probes of the multiple laser detection modules S222 are recorded as h1 to h2. n ;

[0050] Step S4: Using the analysis module S102, determine and model the heights detected by multiple probes. Generate a curved surface using the heights of multiple points to create a model that adapts to the shape of the material surface. Record h for each height. n Simultaneously, the density of each laser point is determined, and the area S around each laser point with a diameter of 0.1mm to 2mm is calculated according to the formula. Get h n The volume of the cylindrical structure at the base point, and the volume V at multiple points. h Perform integrated calculations and finally obtain V 总 This gives us the total volume, which is then used to calculate the total volume V. 总 The total mass M is obtained by multiplying the mass M by the density ρ, and the overall model is then displayed by the operator through the main control system S1.

[0051] Step S5: Use the sonar verification module S301 in the inspection system S3 to perform sonar verification on the entire interior and top of the material to obtain a coarse sonar model. Compare and correct the coarse sonar model with the detailed overall model obtained in step S4 to verify the accuracy of the model.

[0052] Through the above process, the S101 main control unit can automatically activate various sensors, simplifying the operation process and reducing the need for manual intervention. The step-by-step approach, from initial sensing to density detection and then to laser detection, ensures that the most accurate data is obtained at each step, providing a solid foundation for subsequent modeling. At the same time, by using multi-point height to generate curved surfaces and combining density to calculate the total volume and total mass, an accurate material model is formed, improving the depth and breadth of data analysis. Finally, workers can intuitively view the status and model of the material through the main control system, facilitating real-time monitoring and management.

10. The measurement system for multi-point synchronous measurement according to claim 9, characterized in that, The main control system (S1) and the detection system (S2) include the following working steps: Step S1: The main control system (S1) triggers the sensor through the main control terminal (S101), detects the feeding depth of the material through the sensor, and makes a preliminary sensing judgment through the sensing module (S211). Step S2: After the depth is initially sensed by the sensing module (S211), the compactness detection module (S221) is activated to push and detect the material to determine the compactness of the material and obtain the actual compactness ρ. Step S3: Further, the material is detected from the top of the material pile using a laser detection module (S222) to determine the material feed rate and precise height. The heights recorded by the probes of the multiple laser detection modules (S222) are respectively recorded as h. (1) h (2) h (3) ...h (n) , where h (n) For any recorded elevation point; Step S4: Using the analysis module (S102), determine and model the heights detected by multiple probes, generate a curved surface using the heights of multiple points, and thus create a model that adapts to the shape of the material surface. Record h for each height. (n) Simultaneously, the density of each laser point is determined, and the area S around each laser point with a diameter of 0.1mm to 2mm is calculated, according to the formula V = S·h. n Get h (n) The volume of the cylindrical structure at the base point, and the volume V at multiple points. h Perform integrated calculations and finally obtain V. 总 This gives us the total volume, which is then used to calculate the total volume V. 总 The total mass M is obtained by multiplying the mass M by the density ρ, and the overall model is then displayed by the operator through the main control system (S1). Step S5: Use the sonar verification module (S301) in the inspection system (S3) to perform sonar verification on the entire interior and top of the material to obtain a coarse sonar model. Compare and correct the coarse sonar model with the detailed overall model obtained in step S4 to verify the accuracy of the model.
