Description

Technical Field

[0001] The present invention relates to the technical field of safety valve calibration, and specifically to a safety valve calibration label and calibration system based on contact calibration technology. Background Art

[0002] Currently, the calibration of safety valves mainly adopts the method of removing them for inspection. After calibration, metal labels or paper certificates are installed, but there are the following problems:

[0003] 1. Unable to verify remotely: Traditional labels need to be viewed closely at a height, making it difficult to verify whether the calibration information matches the physical object.

[0004] 2. Prone to forgery or tampering: Metal labels can be detached and replaced, posing a risk of forgery.

[0005] 3. Unable to update dynamically: If the state of the safety valve changes (such as rusting, clogging) after calibration, the label cannot reflect the real situation.

[0006] 4. Limitations of the existing technology: Some solutions use QR codes or NFC tags, but still need to be read in close proximity and cannot monitor the state of the safety valve in real time. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the above technical defects.

[0008] To solve the above problems, the technical solution of the present invention is: A safety valve calibration label based on contact calibration technology, including an anti-tampering electronic label, a contact pressure detection module, and a data communication module;

[0009] The anti-tampering electronic label uses one of RFID, NFC, and QR code to store the unique code and calibration data of the safety valve. The contact pressure detection module is located on one side above the anti-tampering electronic label and is connected to the anti-tampering electronic label. It can collect the inlet pressure of the safety valve by one of magnetic attraction and plugging methods. The data communication module uses one of Bluetooth, Wi-Fi, and NB-IoT for remote data synchronization, and the data communication module is connected to the anti-tampering electronic label.

[0010] Further, the RFID, NFC, and QR code are non-contact, batch-readable, and environment-resistant.

[0011] A calibration system for a safety valve calibration label based on contact calibration technology, the calibration system includes the following operating steps:

[0012] Step 1: Label installation: After calibration, fix the electronic label on the safety valve body and the nearby pipeline to ensure anti-disassembly and high temperature resistance;

[0013] Step 2: Data entry: The verification agency writes verification data through special equipment and synchronizes it to the supervision system;

[0014] Step 3: On-site inspection: The supervision personnel use a handheld device to touch the label, automatically read the information and compare the pressure data to quickly judge the status of the safety valve.

[0015] Furthermore, both the special equipment and the handheld device adopt existing readers and handheld instruments.

[0016] Furthermore, a high-temperature adhesive layer is provided on the rear side of the anti-tampering electronic label.

[0017] The advantages of the present invention compared with the existing technology are as follows:

[0018] The present invention is provided with an anti-tampering electronic label that adopts RFID, NFC or two-dimensional code technology, stores the unique code of the safety valve, verification data (including setting pressure, verification date, next verification time, etc.), and has an encrypted storage function to prevent data from being tampered with. The contact verification module integrates a micro pressure sensor, which can detect the inlet pressure of the safety valve regularly or in real time and compare it with the verification threshold stored in the label to judge whether the safety valve is in a normal state. The wireless communication module (optional) supports Bluetooth, Wi-Fi or NB-IoT communication technology and is used to remotely upload verification data to the supervision platform. The anti-disassembly structure is fixed by a high-temperature adhesive or a mechanical locking method and automatically fails after being damaged to ensure that the label cannot be disassembled.

[0023] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0024] To make the content of the present invention easier to be clearly understood, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] As Figures 1 to 2 shown, a safety valve calibration label based on contact verification technology includes an anti-tampering electronic label 1, a contact pressure detection module 2 and a data communication module 3;

[0026] The anti-tampering electronic label 1 adopts one of RFID, NFC and two-dimensional code, and is used to store the unique code and calibration data of the safety valve. The contact pressure detection module 2 is located on one side above the anti-tampering electronic label 1, and is connected to the anti-tampering electronic label 1. It can collect the inlet pressure of the safety valve by one of magnetic attraction and plug-in methods. The data communication module 3 adopts one of Bluetooth, Wi-Fi and NB-IoT for remote data synchronization. The data communication module 3 is connected to the anti-tampering electronic label 1. The RFID, NFC and two-dimensional code are non-contact, batch-readable and environment-resistant.

[0027] A calibration system for a safety valve calibration label based on contact verification technology, the calibration system includes the following operation steps:

[0028] Step 1: Label installation: After calibration, fix the electronic label on the safety valve body and the nearby pipeline to ensure anti-disassembly and high temperature resistance;

[0029] Step 2: Data entry: The calibration agency writes the calibration data through a dedicated device and synchronizes it to the supervision system;

[0030] Step 3: On-site inspection: The inspector uses a handheld device to contact the label, automatically reads the information and compares the pressure data to quickly judge the status of the safety valve.

[0031] The dedicated device and the handheld device both adopt existing readers and handheld instruments. A high-temperature adhesive layer 4 is provided on the rear side of the anti-tampering electronic label 1.

[0032] In specific use, first, calibration data writing: After the calibration agency completes the calibration of the safety valve, write the calibration data into the electronic label and synchronize it to the supervision platform. Secondly, contact verification: Contact the label through a handheld device (such as a dedicated detector or a smart phone) to read the calibration information. At the same time, the device collects the current pressure of the safety valve through a contact sensor (such as a magnetic attraction pressure probe) and compares it with the set pressure stored in the label to judge whether it is abnormal. Finally, dynamic update: If a pressure abnormality (such as blockage or leakage) is detected, the label can record the abnormal event and upload an alarm.

[0033] The above describes the present invention and its embodiments. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
