Fully digital oxygen generator monitoring and control system

Abstract

The invention provides a monitoring and controlling system of a full-digital oxygenerator. The monitoring and controlling system comprises a pressure detection device, a temperature detection device, a controller, a photocoupling isolating device, a display device and a power supply device. The pressure detection device is connected with the oxygenerator and used for detecting system pressure signals of the oxygenerator. A probe of the temperature detection device stretches into the oxygenerator, and the temperature detection device is used for detecting internal operating temperature signals of the oxygenerator. The controller is connected with the pressure detection device and the temperature detection device and used for setting a time interrupt source and an AD interrupt source. The photocoupling isolating device is connected with the controller and used for carrying out photocoupling isolation on the controller and an external circuit. The display device is connected with the controller and used for displaying pressure data, temperature data and time data after data algorithm processing. Digital control is adopted in the system, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oxygen generator equipment, in particular to an all-digital oxygen generator monitoring and control system. Background technique [0002] The medical molecular sieve oxygen generator uses zeolite molecular sieve as the adsorbent, uses pressure swing adsorption (Pressure SwingAdsorption, PSA) to use air as the raw material at room temperature and low pressure, and directly separates the oxygen in the air (about 21%) by physical methods. , so as to produce high-purity medical oxygen with a concentration of 90% to 96%, which is characterized by fast oxygen production, safety, economy, convenience, and easy replacement of bottled oxygen and chemical oxygen production in the past, and has been widely used. While ensuring the safe and effective operation of the oxygen generator, the rapid oxygen output and the basic functions of medical standards, each oxygen generator manufacturer also continuously updates its...

Problems solved by technology

[0007] 4) Depending on the hardware to adjust the operating parameters of the oxygen generator, due to the drift of the resistance value with the temperature, it will inevitably affect the continuous high-concentration oxygen production capacity of the oxygen generator

[0008] To sum up, some of the functions included in these oxygen concentrators cannot meet the needs of the current market and the maintenance and protection of oxygen concentrators and users, so that users do not have a comprehensive understanding of oxygen concentrators. There is no effective and clear guarantee for safety and user safety. At the same time, there is no clear guidance for maintenance personnel to judge faults, which makes the maintenance and repair time of oxygen generators longer.

Moreover, the functions contained in the existing molecular sieve oxygen generators are not comprehensive enough, and the alarm function only stays at the level of sound and light alarms, and cannot digitally and intuitively display the relevant alarm information and digital adjustment parameters inside the oxygen generator to the user.
