Description

Technical Field

[0001] This utility model belongs to the field of automation instrumentation training, specifically an integrated transmitter parameter setting and valve positioner calibration training device. Background Technology

[0002] In the field of industrial automation, the ability to set and calibrate parameters for transmitters and valve positioners is a core skill for instrument engineers. Configuring transmitter parameters requires completing operations such as unit selection, zero-point calibration, range setting, damping time adjustment, and meter display settings, directly affecting the accuracy and stability of the measurement signal. Valve positioner calibration, on the other hand, requires precise execution of zero-range calibration and valve position response verification steps to ensure accurate matching between the valve actuator and the control signal.

[0003] However, the current industry suffers from significant shortcomings in technical training. Firstly, traditional training methods use separate equipment for transmitter calibration and valve positioner debugging. This fragmented training makes it difficult for trainees to grasp the complete control chain of the transmitter. Secondly, existing training equipment typically uses a fixed configuration of a single type of transmitter and valve positioner, unable to flexibly replace them with temperature, level transmitters, or angular stroke valve positioners. This fails to cover the diverse needs of different industries, resulting in a disconnect between training content and real-world industrial applications. Finally, modifying critical instrument parameters during operation is strictly prohibited in industrial settings, but purely theoretical training fails to allow trainees to perceive the consequences of misoperation. Even experienced instrument engineers, after prolonged periods away from practical operation, are prone to developing operational inertia and errors. The lack of a safe and reliable retraining platform for skill verification and correction further exacerbates the problem; traditional training devices lack inherent safety design, making it difficult to reproduce hidden fault scenarios caused by parameter cascading errors in a risk-free environment. Utility Model Content

[0004] The purpose of this invention is to address the problem that independent training devices for transmitters and valve positioners cannot simulate the coordinated operation of equipment in real industrial scenarios, resulting in blind spots in safe operation and making it difficult for trainees to master the composite skills of collaborative debugging of industrial automation devices. This invention provides an integrated training device for transmitter parameter setting and valve positioner calibration, breaking the traditional fragmented training model by integrating transmitter calibration and positioner debugging into a unified control loop. This helps improve trainees' ability to set transmitter parameters in actual work, ensuring the accuracy and stability of measurement results. It enables employees to quickly master the calibration steps, precautions, and solutions to common problems of valve positioners, ensuring precise valve operation.

[0005] The technical solution of this utility model is an integrated transmitter parameter setting and valve positioner calibration training device, which includes a handheld terminal, a transmitter, a signal conditioner for signal conversion, a valve positioner and a regulating valve connected in sequence.

[0006] The handheld terminal is connected to the transmitter via a data cable;

[0007] The input terminal of the signal conditioner is electrically connected to the transmitter via a data line;

[0008] The output of the signal conditioner is electrically connected to the valve positioner via a data line;

[0009] The valve positioner is bolted to the regulating valve.

[0010] Furthermore, the transmitter's output is electrically connected to the digital display's input via a data line; the digital display's output is electrically connected to the signal conditioner's input via a data line.

[0011] Furthermore, the output of the valve positioner is connected to the input of the safety barrier via a data cable, and the output of the safety barrier is connected to a multimeter via a data cable.

[0012] Furthermore, the valve positioner is connected to a computer via a modem.

[0013] Furthermore, the valve positioner is connected to a modem via a data cable, and the modem is connected to a computer port via a data cable.

[0014] Furthermore, the integrated transmitter parameter setting and valve positioner calibration training device also includes a power supply module, which includes a first circuit breaker, a second circuit breaker, and a power converter.

[0015] Furthermore, in the power module, the output terminal of the first circuit breaker is connected in parallel with the input terminal of the power converter and the power port of the digital display meter via a wire, the output terminal of the power converter is connected to the input terminal of the second circuit breaker via a wire, and the output terminal of the second circuit breaker is connected in parallel with the power port of the signal conditioner and the power port of the safety barrier via a wire.

[0016] The beneficial effects of this utility model are:

[0017] (1) This utility model realizes the integration of transmitter parameter setting and valve positioner calibration into a unified control loop, enabling students to fully master the composite skills of collaborative debugging of industrial automation devices, effectively solving the problem of difficulty in understanding the complete control link caused by traditional fragmented training, and greatly improving the students' overall cognitive level of industrial automation devices.

[0018] (2) This utility model adopts a combination of digital display and multimeter. Trainees can master the setting of transmitter and the adjustment of valve positioner in actual operation, and observe the changes in the fluctuation range of digital display and multimeter values ​​at the same time, so that trainees can accurately compare the deviation between target signal and actual action, and ensure measurement stability and valve control accuracy.

[0019] (3) This utility model provides a practical and safe training environment for trainees by using the first and second circuit breakers in the power module to achieve overload protection and the safety barrier to isolate the output signal of the valve positioner. In this environment, trainees can fully perform practical operations, review and consolidate theoretical knowledge, discover and correct possible operational errors, and simulate hidden fault scenarios such as parameter cascade errors. This effectively improves trainees' skills and awareness in safe operation, solves the problem that traditional training devices lack inherent safety design and cannot reproduce complex fault scenarios without risk, and makes up for the safety training blind spots caused by the prohibition of online debugging in industrial sites.

[0020] (4) This utility model meets diverse training needs and has high flexibility. The transmitter can be arbitrarily replaced with various types of transmitters such as temperature, pressure, and liquid level according to different training needs; the valve and positioner can also be replaced with different forms such as angular stroke and linear stroke. This enables the device to fully cover the differentiated needs of different industries, effectively avoids the drawbacks of existing training equipment with single configuration and inflexible adjustment, and makes the training content closely fit the complex and ever-changing actual situation of industrial sites.

[0046] The working principle of this integrated training system is as follows:

[0047] The trainee first uses the handheld terminal 6 to set the parameters of the transmitter 5. After the setting is completed, the transmitter 5 starts to collect physical quantity signals and converts them into 4-20mA analog signals, which are then output to the digital display 4. The digital display 4 converts the analog signals into switch signals according to the preset high or low limits and outputs them as switch signals. The switch signals are then input to the signal regulator 7. After receiving the switch signals, the signal regulator 7 converts them into standard 4mA or 20mA analog signals and inputs them to the valve positioner 9. The valve positioner 9 controls the control valve 12 to open or close according to the received signals. In addition, the trainee uses the computer 13 to output analog signals through the modem 10 to control the valve positioner 9 and then adjusts it to ensure that it can accurately control the action of the control valve 12.

[0048] After the regulating valve 12 performs its corresponding action, it transmits the mechanical displacement back to the valve positioner 9 through a feedback mechanism. The valve positioner 9 then converts this mechanical displacement into a standard 4-20mA DC signal and inputs it into the safety barrier 8. The safety barrier 8 serves as a signal isolation and safety protection mechanism, while the actual current value is displayed by the multimeter 11, allowing trainees to monitor the signal status in real time.

[0049] The entire process forms a complete closed-loop control device, allowing trainees to deeply understand the linkage between "sensing and execution" and master skills in various aspects such as transmitter parameter setting, valve positioner calibration, and device collaborative debugging.
