Description

Technical Field

[0001] The present invention relates to a physiological multi-parameter monitoring device suitable for plateau tunnel environment, in particular to a monitoring device suitable for plateau tunnel construction environment and capable of simultaneously monitoring environmental parameters and human physiological characteristics; and belongs to the technical field of environmental monitoring and biomedical engineering. Background Art

[0002] The construction environment of plateau tunnels is harsh, and factors such as low oxygen, high cold, and humidity pose a serious threat to the personal safety and health of construction workers. Traditional environmental monitoring equipment can usually only monitor a single environmental parameter, such as temperature, humidity, or oxygen concentration, and cannot fully reflect the complex environmental conditions in plateau tunnel construction. At the same time, traditional medical equipment is usually used to monitor the physiological status of construction workers, which is not only inconvenient to wear, but also unable to monitor and warn in real time.

[0003] The development of a monitoring device that can simultaneously monitor the plateau tunnel environment and human physiological characteristics is of great significance for ensuring construction safety and improving work efficiency.

[0004] In recent years, with the rapid development of sensor technology and information processing technology, multi-parameter environmental monitoring technology and biomedical engineering technology have gradually been applied to the field of plateau tunnel construction. These technologies can monitor the environmental parameters and human physiological status in the tunnel in real time and accurately, providing decision-making basis for managers.

[0005] At present, there are some devices for environmental and physiological characteristics monitoring on the market, but they have certain limitations in terms of applicability, accuracy and real-time performance. Specifically, the existing technologies have the following defects: 1. Limited applicability: Some traditional environmental monitoring equipment usually only monitors a single environmental parameter, such as temperature, humidity or oxygen concentration or human physiological characteristics. In the plateau tunnel construction environment, these devices are often unable to fully reflect the environmental conditions due to the particularity of geographical and climatic conditions, resulting in inaccurate monitoring results; 2. Insufficient accuracy: Affected by the plateau environment, some monitoring equipment is easily disturbed due to technical limitations or limitations of the materials used, and its accuracy is difficult to guarantee. For example, some physiological characteristic sensors are affected by factors such as electromagnetic interference and motion artifacts, which may cause distortion of measurement results; 3. Poor real-time performance: Affected by the high altitude, low air density, low atmospheric pressure and increased air viscosity coefficient of the plateau environment, the equipment may not work properly.

[0006] In summary, the existing monitoring equipment still has some problems, such as low equipment integration, incomplete monitoring indicators, unstable data transmission, etc.; it is impossible to simultaneously and accurately monitor the plateau tunnel environment and human physiological characteristics, resulting in the inability to provide timely warnings and take countermeasures.

[0007] Therefore, providing a physiological multi-parameter monitoring device suitable for plateau tunnel environment to solve the above problems, with equipment integration, comprehensive monitoring indicators, stable data transmission, intelligent processing, visual interface, good applicability, energy saving and environmental protection, has become a technical problem that needs to be urgently solved in this technical field.

[0035] The gateway in the physiological multi-parameter monitoring device suitable for plateau tunnel environment of the present invention adopts the WEB configuration industrial gateway of Beijing Hexinyunda Technology Co., Ltd.; the display screen adopts the display screen with model DC12480EW068 of Guangzhou Dacai Optoelectronics Technology Co., Ltd.; the positioning sensor adopts the ZL-GPS-012 sensor of Chongqing Zhanlian Technology Co., Ltd.; the temperature sensor, humidity sensor, air pressure sensor, positioning sensor, oxygen concentration sensor, and carbon dioxide concentration sensor adopt the products of Jinan Keyu Electronic Information Technology Co., Ltd.;

[0036] The health monitoring module (health monitor) in the physiological multi-parameter monitoring equipment suitable for plateau tunnel environment of the present invention adopts Yongkang 8000c to perform bedside non-invasive monitoring of patients' electrocardiogram, heart rate, body temperature, respiration, non-invasive blood pressure, blood oxygen, pulse rate, and respiratory vital sign parameters; performance requirements: heart rate: measurement range: adult: 15bpm~300bpm; error should be ±1% or ±1bpm, whichever is greater; blood pressure: measurement range: 0~300mmHg; measurement accuracy: ±3mmHg, static pressure measurement range;

[0037] Type of application: Systolic blood pressure, Diastolic blood pressure, Mean blood pressure

[0043] b) The detection range for children is 0BrPM~150BrPM;

[0044] c) The detection range for newborns is 0BrPM~150BrPM;

[0045] The operation of the health monitor in the physiological multi-parameter monitoring device suitable for plateau tunnel environment in Example 1 of the present invention is as follows: select the corresponding health monitor accessories according to the needs of the user, and ensure that the connection between the accessories and the health monitor host is successful, connect the required accessories, correctly place the blood oxygen probe, monitor the blood oxygen saturation and pulse rate, and set the alarm according to the detection value of the user; correctly place the cuff, perform non-invasive blood pressure monitoring, and set the alarm parameters according to the detection value of the user; correctly connect the electrocardiogram lead wire, perform heart rate monitoring, and set the alarm parameters according to the detection value of the user; correctly place the temperature probe, perform temperature monitoring, and set the alarm parameters according to the detection value of the user; observe and record each parameter.

[0046] The environment in which the physiological multi-parameter monitoring device suitable for plateau tunnel environment of embodiment 1 of the present invention is used is a plateau tunnel construction environment, which has the characteristics of high altitude, low air density, low atmospheric pressure, increased air viscosity coefficient, reduced number of air molecules, reduced heat transfer, large dust, and many harmful gases. The equipment has the following characteristics: 1. It should have increased heat dissipation capacity. Due to the increase in air viscosity coefficient in the plateau environment, the number of molecules in the local area is reduced, so that the temperature of the heating element is not easy to dissipate, resulting in excessive local temperature rise of the equipment. If the heat dissipation is not timely, some devices will burn out; 2. The spacing between electronic devices should be increased accordingly in the circuit board design. The higher the sea wave, the thinner the air, the lower the strength of the insulating medium, and insulation breakdown will occur, and the equipment will not be able to continue to work normally; 3. Under the premise of ensuring the normal operation of the equipment, dust prevention treatment should be increased as much as possible;

[0047] By setting an intake fan on the top of the chassis, the cold air from the outside enters the chassis and then sinks to mix with the hot air in the box to achieve the purpose of cooling. At the same time, a good dust-proof effect is achieved with the help of the dust cover and electrostatic filter. The test uses dust of different particle sizes and conducts a simulation test for twenty minutes. After opening the chassis, it was found that there was no obvious dust entering the inside of multiple chassis, the equipment temperature was normal, and only a large amount of dust was deposited outside the dust cover, which makes the overall equipment better for use in the plateau tunnel construction environment.
