A life signal synchronous measurement system and measurement method for biological radar detection

Abstract

The invention discloses a life signal synchronous measurement system and a measurement method for biological radar detection, belonging to the technical field of biological radar and life signal measurement. It includes multiple touch sensor groups and control display terminals; each touch sensor group includes a piezoelectric respiration sensor and a photosensitive pulse sensor; the control display terminal includes a computer and a Bluetooth router, and the touch sensor group communicates with the Computer communication: The computer communicates with the biological radar system to monitor the working status of the biological radar system. Use the Hook technology in the Windows message mechanism to establish a third-party software monitor, that is, use the hook to capture the event message of the start / stop measurement of the biological radar system software, and immediately trigger the start of the synchronous measurement system when monitoring the event of the biological radar start / stop saving data / Stop saving data to realize the time synchronization of the data collected by the two.

Description

technical field [0001] The invention belongs to the technical field of biological radar and life signal measurement, and relates to a life signal synchronous measurement system and measurement method for biological radar detection. Background technique [0002] Bio-radar is a new type of radar technology that uses living organisms (human body or animals) as the detection object. It uses electromagnetic waves emitted by special radars as the detection medium, which can penetrate non-metallic barriers such as clothing, bushes, walls, ruins, etc., and obtain non-contact data. Human target information has broad application prospects in military, public security, biomedicine and other fields. [0003] As a new type of non-contact life detection technology, the experimental research on bio-radar technology often needs to evaluate the reliability and accuracy of the detection results. Domestic and foreign literature shows that the evaluation of biological radar experiment results ...

Problems solved by technology

[0004] At this stage, the synchronous measurement system used for bio-radar detection uses human respiration, electrocardiogram, pulse and other signals detected by contact methods as references, and compared with commercialized human physiological information measuring instruments such as multi-conductor physiological recorders, The system developed using small contact sensors such as ECG electrodes and photoelectric sensors not only has advantages in cost, volume, and weight, but is also more suitable for biological radar detection experiments in various scenarios, such as simulated ruins in the field and multi-human target detection etc., but when used simultaneously with a bioradar system, there is the question of how the signals measured by the two are synchronized in time - that is, how to manipulate the software of both systems at the same time so that they start / stop measurements at the same time
