Description

Technical Field

[0001] This invention relates to the field of physiological monitoring and cold protection technology, specifically to a physiological monitoring and control system applied to extreme cold protection equipment. Background Technology

[0002] During high-altitude climbing, polar scientific expeditions, and other operations in extremely cold environments, the human body is susceptible to threats such as frostbite, hypothermia, and lack of oxygen in the environment, requiring high reliability in cold protection, warmth preservation, and physiological state monitoring.

[0003] Current protective methods in extremely cold environments mainly rely on traditional thermal clothing combined with simple heating devices, which can only achieve basic insulation and have a low level of intelligence. These devices usually cannot effectively monitor the temperature of key parts of the body, nor can they adaptively adjust insulation strategies based on monitoring results, resulting in insufficient safety and flexibility in use.

[0004] Furthermore, traditional cold-weather heating equipment has a relatively simple structure and limited functional integration, making it difficult to effectively combine monitoring information with control actions, thus failing to form an integrated safety protection system for extremely cold environments. Therefore, there is a strong practical application need to develop a protection system that can simultaneously achieve temperature monitoring, zoned insulation control, and environmental parameter monitoring. Summary of the Invention

[0005] To overcome the above-mentioned shortcomings in the prior art, the present invention provides a physiological monitoring and control system for extreme cold protection equipment with multi-parameter feedback adjustment and improved safety.

[0006] The technical solution of this invention is as follows: A physiological monitoring and control system for extreme cold protection equipment includes a control unit, a temperature detection unit, an oxygen concentration detection unit, a multi-channel heating unit, and a wireless transmission unit. The temperature detection unit, the oxygen concentration detection unit, the heating unit, and the wireless transmission unit are all electrically connected to the control unit; The heating units are arranged in sections within the human body's warmth-keeping area; The control unit adjusts each heating unit according to the collected signals, and performs oxygen supply regulation according to abnormal oxygen concentration.

[0007] Preferably, the temperature detection unit includes multiple distributed temperature sensors, and each temperature sensor is configured corresponding to the heating unit.

[0016] The physiological monitoring and control system of the present invention, applied to extreme cold protection equipment, transmits the collected temperature and oxygen concentration signals to the control unit through a temperature detection unit and an oxygen concentration detection unit. The control unit controls the multi-channel heating units arranged in zones in real time according to the collected parameter signals, and simultaneously controls the oxygen supply when the oxygen concentration is abnormal, so as to realize closed-loop feedback control of parameters, thereby ensuring the safety of personnel under extreme cold conditions.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

These terms are used solely for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Example 1: The extreme cold condition physiological monitoring and insulation system provided in this embodiment is mainly suitable for extreme environments such as high-altitude snow mountain climbing, polar scientific research, and field operations in extremely cold regions. It can accurately keep the body warm in key areas under extreme conditions and simultaneously monitor physiological state and environmental gas parameters in real time, ensuring the safety and health of personnel working in extreme environments.

[0021] like Figure 1 As shown, the extreme cold condition physiological monitoring and insulation system in this embodiment includes a control unit, a temperature detection unit, an oxygen concentration detection unit, a multi-channel heating unit, a wireless transmission unit, and a power management unit. All functional units are electrically connected through integrated wiring terminals. The overall structure is compact and highly integrated, and can be embedded in cold-weather clothing or stored in a portable shell to meet the needs of portable use in the field.

[0022] In this embodiment, the multi-channel heating units are arranged in zones according to the core warmth requirements of the human body, specifically distributed in key muscle groups and frostbite-prone areas such as the hands, feet, abdomen, back, waist, and thighs. This allows for targeted heating of areas where heat loss is rapid and cold resistance is weak, avoiding the energy waste and uneven local temperature problems caused by traditional monolithic heating. Complementing the heating units, the temperature detection unit employs a multi-channel distributed temperature sensor structure, with each temperature sensor corresponding to a specific heating area. This enables independent and accurate acquisition of the surface temperature of each heated area, providing a reliable data foundation for subsequent zoned closed-loop control.

[0023] In this embodiment, the temperature detection unit is also equipped with a multi-channel analog switch circuit. This circuit uses multiple analog switches to perform time-division multiplexing of temperature sensor signals, ensuring acquisition accuracy while reducing the resource consumption of the control unit's hardware interface and improving the system's operational stability in extremely cold and complex environments. The temperature acquisition loop includes a complete voltage divider sampling and signal conditioning structure, and related auxiliary circuits provide support for the system's reliable operation in low-temperature environments.

[0024] In this embodiment, the control unit, as the core of the system, is equipped with multiple independent PWM output ports. Continuous and adjustable control of the heating power of each heating unit is achieved by adjusting the duty cycle of the PWM signal. Employing PWM pulse width modulation for power regulation avoids the impact and damage to the low-temperature power supply battery caused by continuous high-current operation of the heating circuit, extending the battery's range and lifespan in extremely cold environments. Furthermore, it allows for closed-loop control by combining real-time temperature data, maintaining each heating area within a suitable temperature range, preventing localized overheating or underheating, and improving insulation performance and operational safety.

[0025] In this embodiment, each heating unit is equipped with a corresponding drive amplifier circuit. The weak control signal output by the control unit is amplified by the drive amplifier circuit before driving the heating load. This ensures that the control signal does not fail due to attenuation during low-temperature, long-distance transmission, and guarantees that the heating unit responds sensitively and operates reliably in extreme environments. This drive amplifier structure compensates for the weak load-carrying capacity of low-voltage control signals and is an important guarantee for the system to stably achieve zoned heating under extremely cold conditions.

[0026] In this embodiment, integrated terminal blocks are used to centrally connect the various functional modules and the control unit. The terminal block structure has a high degree of integration and a small interface size, which is suitable for the compact layout requirements of wearable devices. At the same time, the integrated terminal blocks are provided with multiple sets of interconnected common grounding pins to form a unified grounding terminal for the entire system. This effectively reduces the impact of electromagnetic interference and ground potential fluctuations on analog acquisition signals in extremely cold environments, and further improves the acquisition accuracy of weak signals such as temperature and gas concentration.

[0027] In this embodiment, the power management unit adopts a multi-stage voltage regulation architecture, sequentially implementing 12V to 8V, 12V to 5V, and 5V to 3.3V voltage conversions to provide suitable power supply voltages for the heating load, analog acquisition circuit, control unit, and wireless communication module, meeting the operating voltage requirements of different modules. The power management unit also features voltage monitoring, current acquisition, and reverse connection protection functions, enabling real-time monitoring of battery status and system power consumption. It is compatible with dedicated low-temperature batteries, ensuring normal system startup and continuous power supply in low-temperature environments.

[0028] In this embodiment, the wireless transmission unit adopts a dual-module structure combining short-range and long-range communication, forming a dual-link redundant data transmission mechanism. Short-range communication meets the real-time viewing needs of on-site mobile terminals, while long-range communication enables remote monitoring and data recording of remote devices. Even in extremely cold environments with high altitudes and severe obstruction, stable transmission of monitoring data and equipment status information is guaranteed. The wireless transmission unit can synchronously upload parameters such as temperature data, oxygen concentration information, heating unit operating status, and battery power to an external display unit, achieving comprehensive visualization of the system's operating status.

[0029] In this embodiment, the oxygen concentration detection unit is used to monitor the ambient oxygen content and exhaled gas parameters. When an abnormally low oxygen concentration is detected, the control unit can output an alarm signal in a timely manner and execute the corresponding oxygen supply regulation strategy to remind personnel to evacuate the dangerous area or start the backup oxygen supply equipment. This combines temperature preservation with respiratory safety to form a multi-dimensional extreme environment safety protection mechanism.

[0030] This embodiment organically integrates functions such as zoned precise heating, distributed physiological temperature monitoring, oxygen concentration safety early warning, dual-link wireless transmission, and low-temperature adaptable power management. It constructs an integrated physiological monitoring and thermal control system for special application scenarios with constraints of extreme cold, low oxygen, and high energy consumption. The overall solution has obvious practicality and pertinence in terms of functional combination, scenario adaptation, and control logic, and can effectively solve the problems of low intelligence, high energy consumption, and poor environmental adaptability of traditional cold protection equipment.

[0031] The above-described embodiments are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
