The thin air and low oxygen partial pressure in the western high-altitude areas of China can cause certain discomfort to people moving in the high-altitude areas, and even acute hypoxia diseases such as cerebral edema and the like occur in severe people. In recent years, with the increase of tourism, life and working crowds in the plateau, the demand of the market on the high altitude/oxygen supercharging equipment is increasing day by day.
However, the medical oxygen chamber is common on the plateau at present, only plays a role of emergency treatment, the number of people is limited, and the problem of plateau reaction of a large number of people cannot be well solved.
Aiming at the defects of the existing market, the company designs a supercharging life cabin group which is equivalent to a group building formed by connecting a plurality of single cabins. The control of the pressure environment in the cabin group is difficult because the control is directed at the environment with low external pressure; except for a pure pressure control system, the floor drain, the closestool and the door for entering and exiting all affect the pressure of the environment in the cabin.
As the life cabin designed by the company is a brand-new product, the all-weather 24-hour pressurization service is provided in a cabin group mode, and the physical discomfort caused by the travel in plateau areas and the altitude reaction of office staff is prevented or solved. Because the interior of the life cabin is a relatively closed space and continuously operates for 24 hours, corresponding safety guarantee is particularly important when an emergency occurs. The life cabin emergency escape control system is used as life cabin emergency safety guarantee, relevant safety operation is timely carried out at the emergency moment, and personnel in the cabin are guided to evacuate from the life cabin from a safety exit.

Detailed Description
The invention will be further described with reference to the accompanying drawings, to which the scope of the invention is not limited.
As shown in figures 1-3, the life cabin emergency escape control system is characterized in that a plurality of single cabins of the life cabin are connected to form the emergency escape control system, transition cabins used for entering and exiting are further arranged on the life cabin, a detector is arranged in each single cabin of the life cabin, a main control CPU and a main control auxiliary CPU are electrically connected with the detectors of the life cabin, and the main control CPU and the main control auxiliary CPU are further electrically connected with an alarm, a life cabin door switch, a transition cabin door switch, an emergency door switch and a ventilation pipeline control valve of the life cabin. Namely, the life cabin is subjected to emergency escape control through the main control main CPU and the main control auxiliary CPU.
In this scheme, total accuse main CPU, total vice CPU of controlling all are connected with the detector electricity in life cabin, and total vice CPU of controlling is connected with total main CPU electricity. When the master control auxiliary CPU receives a normal signal of the master control main CPU, the master control auxiliary CPU does not work, and the master control main CPU realizes the control of the detector; when the master control auxiliary CPU receives a fault signal of the master control main CPU, the master control auxiliary CPU is started to realize the control of the detector. The main control main CPU is prevented from being damaged and cannot control escape in time.
In the scheme, four states are obtained through the detection of the master control main CPU and the master control auxiliary CPU: dangerous state, warning state, safe state, comfortable state.
Different states, with different corresponding logic: when a dangerous state is triggered, the transition cabin door is closed to forbid personnel from entering, the life cabin door is opened to completely communicate each single cabin, the emergency door switch is opened to facilitate escape of people, and meanwhile, sound and light are used for alarming; when a warning state is triggered, the air inflow of the ventilation pipeline of the life cabin is increased, and meanwhile, the sound prompt gives an alarm; when the safety state is triggered, only the light alarms; in a comfortable state, no prompt is given.
In the scheme, the detector comprises an oxygen concentration detector, a carbon dioxide concentration detector and an air pressure detector; besides the detection and judgment of the numerical values of the three, the logic judgment is also carried out for the loss condition. And when judging, multiple logic judgments are carried out, so that the judgment error is avoided.
Specifically, the method comprises the following steps: triggering a dangerous state when the oxygen concentration is lower than a dangerous value or the carbon dioxide concentration is higher than a dangerous value;
when the oxygen concentration is lower than the alarm value or the carbon dioxide concentration is higher than the alarm value, triggering a warning state; when the oxygen concentration is normal and the carbon dioxide concentration is lost, a warning state is also triggered; when the oxygen concentration is lost and the carbon dioxide concentration is normal, a warning state is also triggered;
when the oxygen concentration and the carbon dioxide concentration are normal, the air pressure is low or lost, and a safety state is triggered.
In this embodiment, when the emergency door switch is triggered, the fan of the life cabin pipeline is turned off and pressure relief is performed; after pressure relief is completed, the opening and closing door of the transition cabin is also opened, so that rescue workers can conveniently enter rescue in time, and the rescue workers cannot feel uncomfortable due to the completion of the pressure relief.
In this embodiment, an evacuation button is also provided in the life bay, which when pressed directly triggers a hazardous condition.
In the embodiment, a smoke and temperature detector is further arranged in the life cabin, and when the smoke and temperature detector is higher than a set value, a fire alarm signal is triggered, and the signal directly triggers a dangerous state.
The scheme is different from the escape of a common building, and not only simple alarm is required, but also the door is simply opened, so that the internal and external pressure relief work is mainly completed; when escaping, the escape capsule escapes from the cabin through the transition cabin and the emergency escape door; this scheme is because inside pressure release, when the people escaped so, can adapt to external low pressure environment, ensures life safety nature.
The above examples are merely representative of preferred embodiments, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
