Description

Technical Field

[0001] The present invention relates to the technical field of control systems, and particularly to a control system for a portable pressure chamber. Background Art

[0002] Due to its advantages of small volume, light weight and convenient transportation, portable pressure chambers play an increasingly important role in the treatment of diving diseases such as decompression sickness and pulmonary barotrauma. During use, in order to ensure the treatment effect and safety, operators need to constantly monitor the status of the people inside the chamber and at the same time understand information such as the pressure, temperature, humidity, etc. inside the chamber, so as to adjust the status inside the chamber according to the preset plan.

[0003] However, the control devices of traditional portable pressure chambers have problems such as scattered control modules, complex operations, and incomplete display of the internal environment information of the chamber, which restrict their use efficiency and treatment effect.

[0004] In addition, currently, the display of pressure, temperature and humidity of portable pressure chambers is usually set on the chamber body of the pressure chamber, and relevant information cannot be displayed on the display screen of the control system. Therefore, during use, operators need to move to a designated position to view relevant information, which is very inconvenient. And because portable pressure chambers are often small in size, restricted by soft materials, there are often blind spots in their observation windows, and it is difficult for operators to comprehensively master the situation inside the chamber, which is likely to cause potential safety hazards. Summary of the Invention

[0005] In view of the problems and deficiencies existing in the prior art, the present invention provides a novel control system for a portable pressure chamber.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] The present invention provides a control system for a portable pressure chamber, which is characterized in that it includes a control box placed outside the chamber and a connection box placed inside the chamber. An industrial control touch screen, an industrial control all-in-one computer, an oxygen supplementation component, a gas source pressurization component, a decompression component, an in-chamber gas detection component for detecting the oxygen and carbon dioxide concentrations in the chamber, a first absorption control component, a mask gas detection component for detecting the oxygen and carbon dioxide concentrations in the breathing mask, a second absorption control component, and a power supply component for supplying power to the control box are installed in the control box. Both ends of the oxygen supplementation component are respectively connected to an oxygen cylinder and the chamber body through pipes. Both ends of the gas source pressurization component are respectively connected to a gas cylinder and the chamber body through pipes. The decompression component and the in-chamber gas detection component are connected to the chamber body through pipes. The mask gas detection component is connected to the breathing mask inside the chamber through a pipe;

[0008] A temperature and humidity sensor, a pressure sensor and a router are installed in the connection box. The temperature and humidity sensor and the pressure sensor are connected to the inside of the cabin. A box-side wire threading assembly and a cabin-side wire threading assembly are fixed on the connection box. The communication wire of the router passes through the cabin-side wire threading assembly and is connected to the camera inside the cabin. The communication wires of the temperature and humidity sensor, the pressure sensor and the router pass through the box-side wire threading assembly and are connected to the industrial control computer. The power supply wires of the temperature and humidity sensor, the pressure sensor and the router pass through the box-side wire threading assembly and are electrically connected to the power supply assembly. The power supply wire of the camera passes through the cabin-side wire threading assembly and the box-side wire threading assembly in sequence and is electrically connected to the power supply assembly;

[0009] The industrial control computer is used to judge whether the oxygen concentration in the breathing mask is lower than the second set oxygen concentration value. If so, it controls the oxygen supply device for the mask to start oxygen supplementation. When the concentration reaches the second set oxygen concentration value, it controls the oxygen supply device for the mask to pause. It judges whether the carbon dioxide concentration in the breathing mask is higher than the second set carbon dioxide concentration value. If so, it controls the second absorption control component to conduct, and the fan in the carbon dioxide absorption device corresponding to the breathing mask starts to absorb carbon dioxide. When the concentration is lower than the second set carbon dioxide concentration value, it controls the second absorption control component to disconnect.

[0010] The positive and progressive effects of the present invention are as follows:

[0011] The present invention monitors the oxygen concentration, carbon dioxide concentration, cabin pressure, temperature and humidity of the portable pressure cabin in real time through the control system, and realizes the precise adjustment of pressurization, decompression and oxygen supply in the cabin through the industrial control computer. When the user operates, various parameters are centrally monitored and controlled through the control box, greatly improving the use efficiency and treatment effect.

[0012] In addition, the connection box designed in the present invention serves as an external extension device and a transfer connection main body of the control box, protecting internal components such as the router in the connection box from the influence of the pressure in the portable pressure cabin. The temperature and humidity sensor and the pressure sensor are integrated in the connection box, which can collect the pressure, temperature and humidity information in the cabin in real time. Through the connection between the connection box and the camera in the cabin, the image information in the cabin can be obtained in real time, and the collected relevant data information is transmitted to the industrial control computer, and the relevant data and pictures are synchronously displayed on the display screen through the control of the industrial control computer. The design of the connection box simplifies the operation process of the portable pressure cabin, protects the components while enhancing the centralized control function of the control box, and improves the working efficiency and safety of the portable pressure cabin.
