AI Technical Summary

Technical Problem

Traditional monitoring devices struggle to adapt to the thermal expansion and contraction of limbs in low-temperature environments, leading to poor sensor-skin contact and affecting data accuracy. High-frequency vibrations cause relative motion between the sensor and skin, resulting in data distortion and making reliable monitoring impossible in extreme environments.

Method used

It adopts an adaptive constant pressure bonding mechanism and an inertial trigger joint locking mechanism, and uses a bidirectional shape memory actuator and MEMS accelerometer to achieve constant pressure bonding of the strap at low temperatures and rigid connection during high-intensity operations, thereby enhancing the stable contact between the sensor and the skin.

Benefits of technology

Ensuring uniform contact between the sensor and the skin in low-temperature environments suppresses relative motion caused by high-frequency vibrations, improving the accuracy and continuity of data, and providing reliable health monitoring.

Abstract

The invention provides a wearable occupational health data monitoring device for power grid operating personnel. Comprising a self-adaptive constant-pressure fitting mechanism which is used for driving the watchband to expand in a low-temperature environment, so that a sensor module on the back of the watch is in constant-pressure contact with the wrist of a wearer; and the inertia triggering type joint locking mechanism is used for converting the flexible joint between the flexible watch head and the watchband into rigid connection when the impact is detected. The invention provides a self-adaptive intelligent monitoring device for plateau low-temperature, strong-magnetic-field and high-impact working environments. A two-way shape memory actuator and a temperature control valve are utilized, so that the watchband is automatically expanded at low temperature, a wearing gap is eliminated, and accurate and continuous physiological signal monitoring is guaranteed; the MEMS accelerometer and the magnetorheological fluid joint are quickly locked, so that vibration is inhibited, and the monitoring stability is improved; and an antimagnetic structure is constructed by adopting permalloy and a coating, so that the interference of a power-frequency strong magnetic field is resisted. The device obviously improves the adaptability, the reliability and the wearing comfort under extreme working conditions.
