Description

Technical Field

[0001] The present invention relates to the technical field of valve opening detection, and specifically to a non-contact valve opening detection device based on a gyroscope. Background Art

[0002] Valve opening detection refers to the process of measuring and monitoring the opening degree of a valve. In many industrial fields such as chemical engineering, petroleum, and natural gas, the flow control of fluids is crucial. Valves are key devices for controlling fluid flow. By accurately detecting the valve opening, the fluid flow can be precisely adjusted. In chemical production, accurate control of the raw material flow directly affects the quality of the product and the safety of the production process. If the valve opening detection is inaccurate, it may lead to too much or too little raw material input, thus affecting the progress of chemical reactions and even potentially causing safety accidents.

[0003] A Chinese invention patent with the publication number CN115875507B discloses an opening detection device for a valve and a pipeline transportation control device, which relates to the field of valve equipment. The valve has a valve body, a screw rod, and a handwheel. The screw rod can perform a spiral movement on the valve body to adjust the opening degree of the valve. The handwheel is fixedly connected to the screw rod. The opening detection device includes a movable member, and a combination of a first magnet and a first magnetic sensor or a combination of a second magnet and a second magnetic sensor. The movable member is movably connected to the handwheel along the axial direction of the screw rod. The movable member is movably connected to the valve body, and the moving direction of the movable member relative to the valve body is along the circumferential direction of the screw rod. This device can realize the opening detection of the valve.

[0004] In addition, since the sensor signals collected on-site often contain various noises and cannot be directly used to analyze the valve state. It is necessary to extract characteristic signals from the original signals, which usually requires signal amplification and filtering, but the amplified noises also need to be filtered out. This process may be complex and require high technical requirements. In many scenarios, the signals collected by the sensor are stored in the chip and need to be read manually, which greatly consumes human resources and time. In addition, when an abnormal situation is detected, such as the valve being stuck or leaking, if a warning cannot be issued in time, it will affect the transportation efficiency of the oil pipeline and also lead to safety risks due to valve failures. Therefore, the opening detection device for a valve and the pipeline transportation control device disclosed in Chinese invention patent CN115875507B cannot accurately detect the valve state in real time, nor can it timely discover problems and give early warnings.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment:

[0032] Referring to the attached Figures 1 to 6 As shown, a non-contact valve opening detection device based on a gyroscope includes a circuit board 1 and a zero-adjusting button 2. The zero-adjusting button 2 is fixedly installed on the outer wall of the circuit board 1. The zero-adjusting button 2 is used to achieve the function of zero-adjusting the number of turns. A power supply button 3 is fixedly installed on the outer wall of the circuit board 1. The power supply button 3 is used to control the on-off of the circuit board 1 and the battery.

[0033] Furthermore, a drive housing 4 is fixedly connected to the outer wall of the circuit board 1. Grooves 5 are symmetrically formed inside the drive housing 4. A feedback rod 6 is fixedly connected inside the drive housing 4. One end of the drive housing 4 away from the circuit board 1 is fixedly connected to a connecting member 7. The size of the connecting member 7 is adapted to the inner cavity size of the drive housing 4. A screw rod 8 is fixedly connected inside the connecting member 7.

[0034] Furthermore, a single-chip microcomputer is installed inside the circuit board 1. An accelerometer, a gyroscope, a sensor, and a Zigbee chip are installed inside the circuit board 1. The accelerometer and the gyroscope are used to calculate the original angle data.

[0035] Furthermore, the gyroscope is matched with a mass block and a support beam, and is used to detect the change of the differential capacitance value. A capacitor is formed between the mass block and the support beam. When the sensor does not experience acceleration, the mass block remains at the central position, and at this time the capacitance value is stable; when the sensor experiences acceleration, the mass block will move due to inertia, and the capacitance value will change accordingly.

[0036] It should be noted that: the mass block will generate relative movement under the action of acceleration. The sensor is set as a vibration sensor to detect the working state of the valve.

[0037] Furthermore, the accelerometer is regarded as two capacitor plates for capacitance detection and acceleration calculation.

[0038] Furthermore, the gyroscope is used for calculating the angle and the number of turns. The Zigbee chip is used for forwarding the number-of-turns data inside the single-chip microcomputer. The Zigbee module is installed inside the Zigbee chip. By real-time monitoring the number of turns of the valve rotation, the valve state can be accurately detected, problems can be found in time and early warnings can be given, thereby improving the accuracy and efficiency of valve maintenance.

[0039] The working process and principle of the above embodiments are as follows:

[0040] The working steps are as follows:

[0041] First, the operator connects the valve through the screw rod 8, then connects the circuit board 1 to an external battery, and presses the power supply button 3 to make the battery supply power to the circuit board 1. When the instrument starts to rotate, the gyroscope starts to work. When there is no acceleration, the mass block remains at the central position, and at this time, the capacitance value is stable. When the sensor experiences acceleration, the mass block will move due to inertia, causing relative movement of the mass block, resulting in a change in the differential capacitance during the displacement of the mass block. Then, the accelerometer detects the differential content and calculates the acceleration. Subsequently, an attitude resolver is integrated inside the module, and the attitude resolver cooperates with the dynamic Kalman filtering algorithm to accurately output the current attitude of the module in a dynamic environment. Then, the single-chip microcomputer reads the output angle data of the gyroscope to calculate the number of rotation circles of the subsequent valve.

[0042] The single-chip microcomputer judges the angle value to determine whether it is the first rotation. If it is the first rotation, the angle is recorded as a positive number. Thereafter, the data of the gyroscope is obtained in real time for judgment. When the angle value crosses 0 degrees (i.e., the sign of the angle changes), the number of rotation circles is adjusted and recorded. When the angle value changes from positive to negative or from negative to positive and the angle value exceeds the threshold, it is recorded as half a circle. According to the difference between the original angle sign, the real-time angle, and a specific angle (90 degrees or -90 degrees), it is judged whether the number of rotation circles needs to be increased or decreased. Then, the single-chip microcomputer records the number of rotation circles and transmits the calculated number of rotation circle data of the single-chip microcomputer to the inside of the Zigbee chip in real time.

[0043] After the Zigbee module is powered on and starts to work, the Zigbee module uploads data to the terminal module every two seconds. When a certain number of rotations is reached or the rotation stops, the gyroscope will enter the low-power state, and the Zigbee chip will cut off the power supply to it to ensure the battery life. Once it receives rotation or jitter, the gyroscope will continue to enter the working state for angle calculation. The number of rotations calculated in real time is transmitted to the inside of the Zigbee chip through the single-chip microcomputer. When the valve stops rotating or reaches a certain number of rotations, then the sensor detects through the valve and automatically controls the gyroscope circuit to close, enabling the gyroscope to enter the intelligent low-power mode, significantly reducing the energy consumption. This design not only reduces energy consumption but also extends the battery life, reduces the maintenance cost and frequency. Finally, the number of rotations is reset through the zero-adjustment button 2. Through real-time monitoring and early warning, it helps to reduce unexpected shutdowns caused by valve failures, thereby improving the productivity and product quality of the factory. Through data transmission using Zigbee technology, this device can upload data in real time, improving the timeliness and response speed of monitoring. Zigbee technology supports self-organizing networks and multi-level network expansion, enhancing the stability and coverage of the network.
