The following is a detailed description of the industrial displacement sensor and the measuring system for multi-point synchronous measurement. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0033] The present application is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Furthermore, the density component includes: a pressurized tube 2 disposed between two composite sensors 1, a plurality of telescopic sleeves 201 are disposed on the surface of the pressurized tube 2, and the plurality of telescopic sleeves 201 are in conduction with the inside of the pressurized tube 2; a pressurized chamber 202 disposed at the top and bottom of the composite sensor 1, a pressurized plate 203 is slidably connected inside the pressurized chamber 202; an electric push rod 204 is disposed inside the pressurized chamber 202, a terminal end of the electric push rod 204 is connected to the pressurized plate 203, and a pressure sensor 205 is disposed on one side of the pressurized plate 203;

[0037] During use, the electric push rod 204 can push the pressure plate 203 to move, and 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 materials on both sides through the telescopic sleeves 201. In this process, the materials will also give pressure to 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 on the pressure plate 203 is greater than the pressure given to the telescopic sleeves 201 by the materials on both sides. At this time, the critical pressure before the pressure plate 203 moves can be recorded by the pressure sensor 205 and sent to the sensing module S211 in the main control system S1 for sensing and judgment, so as to record the internal density.

During use, first determine the position where the composite sensor 1 needs to be installed, The fixing platform 102 is nailed to a predetermined position and connected to the mounting plate 101 by threaded rotation. The threaded bolt 103 is rotated with a tool to tightly connect the fixing platform 102 and the mounting plate 101. At the same time, it is ensured that both are firmly attached to the inner wall of the container. After the power is turned on, the adsorption motor 105 starts to work and drives the internal threaded rod to rotate.

The double guarantee increases the stability of the installation and is also convenient for disassembly and maintenance.

[0041] A measurement system for multi-point synchronous measurement, comprising: a main control system S1, the main control system S1 at least comprising a main control terminal S101 and an analysis module S102, for controlling and deploying multiple sensors in the system as a whole, and at the same time building models based on the results obtained by the multiple sensors to analyze the overall material quantity in a container; multiple sensors, the multiple sensors are distributed on the inner wall of the container, and the multiple sensors are equidistantly distributed around the inner surface of the container; a detection system S2, the detection system S2 is used to cooperate with the control of the main control system S1 to detect the material in the volume cavity to determine the quantity of the contained material, and establish a containment model; an inspection system S3, the inspection system S3 is used to inspect and determine 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 evenly distributed around the inner wall of the container, realizing all-round and no-dead-angle monitoring of the material status, improving the reliability of the system and the integrity of the data. Finally, through the analysis module S102, the material model can be automatically established according to 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.

[0044] During the working process, the design of the primary detection subsystem S210 and the secondary detection subsystem S220 divides the detection process into two stages, first performing preliminary sensing and then performing detailed detection, which improves the detection efficiency and reduces unnecessary resource consumption. The density detection module S221 and the laser detection module S222 provide more detailed material property information, which helps to generate a more accurate material model.

[0045] Furthermore, the inspection system S3 includes a sonar verification module S301, wherein the sonar verification module S301 includes at least a sonar detection component for detecting cavities.

[0046] Furthermore, the main control system S1 and the detection system S2 include the following working steps:

[0047] Step S1, the main control system S1 starts and triggers the sensor through the main control terminal S101, detects the feeding depth of the material through the sensor, and performs preliminary sensing judgment through the sensing module S211;

[0048] Step S2, after the depth is initially sensed by the sensing module S211, the density detection module S221 is started to perform a push detection on the material to determine the filling density of the material and obtain the actual density ρ;

[0049] Step S3: Further laser detection of the material from the upper part of the material pile is performed by the laser detection module S222 to determine the amount of material fed and the precise height. The heights recorded by the probes of the multiple laser detection modules S222 are recorded as h 1 ~h n ;

[0050] Step S4: Use the analysis module S102 to judge and model the heights detected by multiple probes, generate a surface using the heights of multiple points, and thus generate a model that adapts to the surface shape of the material, and record h for each height. n At the same time, the density of each laser point is judged, so that the area around the laser point is calculated as S with a diameter of 0.1mm to 2mm. According to the formula Get h n is the volume of the cylindrical structure at the basic point, and the volume V of multiple points h Perform integration calculation and finally get V 总 , and the total volume is obtained by the total volume V 总 Multiplying it with the density ρ gives the total mass M and the overall model, which the worker can view through the main control system S1;

[0051] Step S5, use the sonar calibration module S301 in the inspection system S3 to perform sonar calibration on the inside and the top of the material as a whole to obtain a rough sonar model, and compare and calibrate the rough sonar model with the detailed overall model obtained in step S4 to verify the accuracy of the model.

[0052] Through the above process, the main control end S101 can automatically start each sensor, simplifying the operation process and reducing the need for manual intervention. The step-by-step approach from initial sensing to density detection to laser detection ensures that the most accurate data can be obtained at each step, providing a solid foundation for subsequent modeling. At the same time, multi-point heights are used to generate surfaces, and the total volume and total mass are calculated in combination with density to form an accurate material model, which improves the depth and breadth of data analysis. Finally, workers can intuitively view the status and model of the material through the main control system, which is convenient for real-time monitoring and management.
