On-line permanent gas filling monitoring method and system

Abstract

The invention relates to an on-line permanent gas filling monitoring method which is characterized in that an industrial control host is provided and is connected with an industrial data acquisition and communication server; the industrial data acquisition and communication server is networked with a plurality of infrared temperature monitors and a plurality of pressure sensors; the infrared temperature monitors are respectively arranged on the middle part of a gas tank, and the pressure sensors are respectively arranged on a gas filling pipeline, so that the pressure and the temperature of the gas tank can be acquired, and a filling process of the gas tank can be managed and controlled. According to the on-line permanent gas filling monitoring method, infrared detection on temperatures is adopted, so that a user does not need to touch a detected object, and the on-line permanent gas filling monitoring method is suitable for measuring and monitoring of gas industry; an existing target is inducted in real time through a diffuse reflection photoelectric switch, so that a function of counting filled gas bottles is realized, and the temperature of the target can be automatically monitored; furthermore, the industrial data acquisition and communication server is used for sending acquired temperature information and pressure information to the industrial control host, so that concentrative management is facilitated.

Description

technical field [0001] The invention relates to the field of gas tank filling detection, in particular to a permanent gas filling online monitoring method and system. Background technique [0002] During the filling process of the existing gas tank, the temperature in the gas tank cannot be detected in real time, or there are problems such as troublesome measurement methods and complicated measurement devices. If the temperature inside the gas tank cannot be detected in real time, there will be no way to fill a sufficient amount of gas within a safe range. There will be "half bottles" and even "empty bottles" that are not filled, and explosions may occur due to overfilling. [0003] There are three important issues in the permanent gas filling process: one is the filling safety problem, how to find the problem in time when the combustible gas and the combustion-supporting gas are mixed; the other is the filling quality problem, the customer bought our product, we It is nece...

Problems solved by technology

[0002] During the filling process of the existing gas tank, it is impossible to detect the temperature inside the gas tank in real time, or there are problems such as troublesome measurement methods and complicated measurement devices

If the temperature inside the gas tank cannot be detected in real time, there is no way to fill a sufficient amount of gas within a safe range. There will be "half bottles" and even "empty bottles" that have been leaked, and explosions may occur due to overfilling

[0003] There are three important issues in the permanent gas filling process: one is the filling safety problem, how to find the problem in time when the combustible gas and the combustion-supporting gas are mixed; the other is the filling quality problem, the customer bought our product, we It is necessary to be responsible for the product. Sometimes some customers hand in "empty bottles" and get "half bottles" that are underfilled, or even "empty bottles" that are missing. The third is the problem of filling pieces. How many gas cylinders are filled by employees in a month, and how many gas cylinders are filled in each shift, these data are simple but cumbersome, but these are very important for future enterprise management
