Description

Technical Field

[0001] The present invention relates to the technical field of pressure transmitters, and in particular to a normal-temperature aging detection method and system for pressure transmitters. Background Art

[0002] Pressure transmitter is a key equipment widely used in the field of industrial automation. Its main function is to convert physical pressure parameters such as gas and liquid into pneumatic signals or electric signals for remote control and monitoring. Therefore, in order to ensure the measurement sensitivity of the pressure transmitter, it is necessary to carry out room temperature aging test on the pressure transmitter before it leaves the factory to identify defective pressure transmitters and ensure the product quality of the pressure transmitter before it leaves the factory. In the prior art, it is usually focused on simulating the rapidly changing pressure signal received by the pressure transmitter during operation, and evaluating the aging degree of the pressure transmitter under working conditions by analyzing the accuracy and sensitivity of the pressure signal converted into an electrical signal. It is ignored that the measurement sensitivity and accuracy of the pressure transmitter are not only affected by the signal conversion process, but also by various factors such as the pressure transmitter equipment itself and its working environment.

[0003] For example, a Chinese patent with publication number CN117664441A discloses a method and system for detecting aging of a pressure transmitter, including obtaining current data of a circuit where the pressure transmitter to be detected is located, obtaining temperature data of the pressure transmitter to be detected, and obtaining humidity data of the environment in which the pressure transmitter to be detected is located; after normalizing the current data, temperature data, and humidity data, the data are sent to a trained GNA neural network model to obtain the aging result of the pressure transmitter.

[0004] For example, a Chinese patent with the authorization announcement number CN215832900U discloses an intelligent pressure transmitter, which relates to the technical field of pressure transmitters, specifically an intelligent pressure transmitter, including a pressure transmitter, wherein a transfer column is provided at the bottom of the pressure transmitter, and a connecting joint is provided on the external fixed sleeve of the pressure transmitter. The intelligent pressure transmitter, through the coordinated use of a threaded tube and an internal conductive sheet, and a display tray and an external conductive sheet, enables the intelligent pressure transmitter to set mutually matching poles on the outside of the external conductive sheet and the internal conductive sheet. When the external conductive sheet and the poles outside the external conductive sheet contact each other, the display screen outside the display tray can display the pressure and other values ​​detected inside the pressure transmitter, thereby avoiding the connection between the display tray and the pressure transmitter through complicated lines, effectively solving the problem of line aging, and facilitating the maintenance work of the staff.

[0005] The above patents all have the problem raised by this background technology: they ignore that the measurement sensitivity and accuracy of the pressure transmitter are not only affected by the signal conversion process, but also by multiple factors such as the pressure transmitter device itself and its working environment; to solve these problems, the present invention proposes a room temperature aging detection method and system for pressure transmitters. Summary of the invention
