Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-altitude life support transport and control, in particular to a high-altitude transport life support guarantee cabin and a guarantee control method. BACKGROUND

[0002] China is the country with the largest high-altitude area in the world. The high-altitude area is characterized by thin air, high-cold hypoxia, and harsh climate. The special geographical environment brings special challenges to high-altitude emergency disaster rescue.

[0003] The injury and treatment under high-altitude environment are characterized by complex injury, limited treatment environment, difficult search and rescue of the wounded, many factors affecting transport, and limited treatment resources. The combined lethal effect is greatly increased due to the superposition of trauma and high-altitude cold hypoxia factors, and the time-to-treatment and continuity are more important.

[0004] Currently, related equipment and materials such as pressurized oxygen cabins are designed only to alleviate high-altitude reactions and have no life support guarantee and continuous monitoring capability, which cannot meet the treatment and transport needs of trauma combined with high-altitude reaction wounded. The existing pressurized oxygen cabin is made of flexible material, has limited pressure increase, and lacks a suitable interface for a transport vehicle, so it cannot be quickly loaded into a general-purpose vehicle. At the same time, the transport vehicle has a self-adaptive adjustment capability to environmental factors during transportation, which affects the safety and reliability during transportation, including low pressure adjustment accuracy, poor adaptability of the fixing device, and extensive micro-environment control. For example, the wounded fixing belt is manually adjusted and cannot be adjusted in real time according to the vibration and displacement during transport, which may easily cause the wounded to shift if the belt is too loose or may affect blood circulation or cause local tissue damage if the belt is too tight. Temperature adjustment relies on traditional heating / cooling mode and lacks fine heat output control based on temperature difference, which may easily cause the temperature in the cabin to rise or drop suddenly, affecting the comfort and stability of the wounded. SUMMARY

[0005] In view of the above problems, the purpose of the present application is to provide a high-altitude transport life support guarantee cabin and a guarantee control method to solve the problems of the existing equipment that cannot be adapted to various transport platforms and the weak life support capability for severe wounded with superimposed high-altitude reactions.

[0011] The buckle seat is fixed at a position corresponding to the belt fixing position on the upper edge of the lower cabin body;

[0012] The cabin pressure adjusting module is arranged in the lower cabin body, and is used to adjust the pressure of the cabin.

[0013] The cabin pressure adjusting module comprises a central control unit, a booster fan, a booster pipeline, a pressure reduction pipeline and an air pressure sensor;

[0014] The air pressure sensor is arranged in the cabin and is used to measure the air pressure information in the cabin and send the air pressure information to the central control unit;

[0015] The booster fan is fixed to the lower cabin body, and the air outlet of the booster fan is connected with the booster pipeline; the booster fan is used to control the air pressure of the output airflow of the air outlet according to the received control signal;

[0016] The first end of the pressure reduction pipeline is connected with the central control unit, and the second end of the pressure reduction pipeline is connected with the outside of the cabin through a pipeline to realize exhaust pressure reduction;

[0017] The booster pipeline and the pressure reduction pipeline are both provided with a control valve, the control valve is used to control the opening and closing degree of the air path of the pipeline according to the received control signal; the control valve is controlled by the control signal sent by the central control unit;

[0018] The central control unit is used to generate a control signal set according to the air pressure information; the air pressure sensor and the booster fan are connected with the central control unit.

[0019] The central control unit is used to generate a control signal set according to the air pressure information, comprising:

[0020] A historical control signal set is obtained; the historical control signal set comprises a control historical signal and air pressure historical information; the control historical signal comprises fan control signal values at a plurality of historical time points; the air pressure historical information comprises air pressure information measured at a plurality of historical time points; the air pressure information is an air pressure value sequence;

[0022] solve the control optimization model to obtain a solved control optimization model;

[0023] use the solved control optimization model to solve the air pressure information to obtain a fan control signal value at the current time;

[0024] generate a valve control value based on the fan control signal value at the current time and the air pressure information;

[0025] use the valve control value and the fan control signal value to construct a control signal set; the control signal set includes two types of control signals: valve control values and fan control signal values.

[0026] The control optimization model is constructed based on the historical control signal set, including:

[0027] subtract the air pressure historical information from the standard air pressure value to obtain a difference sequence set; each difference sequence in the difference sequence set is obtained by subtracting the standard air pressure value from each air pressure value sequence of the air pressure historical information;

[0032] min F |A1-b|,

[0033] l·l T = 1,

[0034] where F |A1-b| represents the Frobenius norm, and l is the optimization vector to be solved.

[0035] By constructing an optimization model containing historical control signals and air pressure information, the "self-learning" ability of air pressure regulation is realized. Compared with traditional open-loop control, this model can optimize the current control strategy according to the historical regulation law, reduce air pressure fluctuations (such as minimizing the Frobenius norm to reduce the overall deviation of the actual air pressure from the standard value), and make the cabin air pressure quickly and stably in the target range (such as simulated plain air pressure or specific treatment air pressure), reducing the stimulation of low air pressure on the respiratory and circulatory systems of the wounded.

[0104] minF|Al-b|,

[0105] l·l T =1,

[0106] wherein F|Al-b| represents the Frobenius norm, and l is an optimization vector to be solved.

[0107] The control optimization model is solved by solving the optimization vector to be solved in the control optimization model, and a numerical solution method or a genetic algorithm can be used.

[0115] The electric tensioner is used to collect the sequence of instantaneous displacement values and the vibration information, generate a tension value according to the sequence of instantaneous displacement values and the vibration information, and apply a tension force directed to the clamping seat to the belt to adjust the winding length of the belt according to the tension value.
