What is the principle of the personnel fall monitoring alarm system?

At present, the market is provided for the elderly to use, there are a variety of technical principles of fall detection alarm, common technologies are millimeter wave radar technology, camera technology, infrared technology, acceleration principle, etc., the product types are: non-inductive fall detection alarm, fall alarm camera, infrared fall alarm, wearable fall alarm (fall alarm bracelet, watch, etc.), in addition to the rope, button and other types of active trigger alarm equipment.

Among them,Fall detection alarm with millimeter-wave radar technologyIt can well avoid several common problems of the elderly in the use of fall alarm equipment

1.Buttons and rope products cannot realize the active alarm of the equipment;

2.High false alarm rate of infrared, acceleration principle and other equipment;

3.Wearable devices are easy to be forgotten by the elderly to wear, forget to charge, sleep and bathe, unable to wear or unwilling to wear;

4.Cameras invade privacy;

The millimeter-wave radar technology "non-inductive fall detection alarm" provided by Dianke uses millimeter-wave technology, full privacy, and can be applied to complex application scenarios

1.The detection range is up to 20 square meters;

2.Full privacy, able to apply to complex application scenarios;

3.It can accurately detect various postures;

4.It can be mounted on both walls and ceilings;

5.There is an anti-false alarm mechanism;

6.There are vital signs detection and reminder functions;

The company has come fromSilicon Valley, USAand the top scientific and technological team of sensor technology and artificial intelligence technology in China. It has independent core technology and excellent industrialization capabilities.

currently on the marketFall monitoring devicesThere are all sorts, and there are common onesInfrared, camera, and millimeterwaves, infrared accuracy is slightly worse, and the camera violates privacyMillimeter WaveIt solves the problems of both, and has greatly improved accuracy and privacy protection, which is the direction of current technology.

Vayyar Care is one such millimeter-wave monitoring device, providedContactless fall monitoring, alarm, and health monitoringSolution, using non-contact millimeter wave fall detection technologyNo invasion of privacy, and no drawstring buttons。If a resident falls, it can immediatelyAutomatically detect falls, raise alarms, and call for help。It uses completely harmless radio waves, which are only one thousandth the strength of a cell phone signal.

Simply install it on the wall or ceiling of the room and you're ready to go24/7Uninterrupted monitoring, real-time fall automatic alarm and activity monitoring, and access to rich elderly activity data, which helps to comprehensively understand the health data of the elderly, so as to formulate personalized health care plans.

There is no need to wear any equipment.

Fully automatic monitoring, automatic alarm, no need to pull ropes, buttons.

Non-camera, no invasion of privacy.

Fall monitoring simulation scenario, automatic alarm.

Personnel fall monitoring and alarm system based on intelligent analysis, monitoring personnel falls in the monitoring area, when found that personnel fall in the fastest and best way to carry out early warning, truly achieve pre-warning, normal detection in the event, standardized management after the event, and free security operators from the complicated and boring "staring at the screen" task.

The core of fall monitoring is the accelerometer, which mainly analyzes the following four aspects:

Changes in the inclination of the human body relative to the ground (from upright to approximate level in a short period of time) The angular velocity of the human body relative to the ground is abnormally high.

Abnormal peak of human gravitational acceleration (front peak + rear trough, fall impact) After the occurrence of the above abnormal events, after a fall is detected after a long period of stillness (coma or inability to move after a fall), follow-up alarm actions are carried out according to the characteristics of the equipment, such as vibration, sound and light, text message or dial**.

Therefore, the research and development of products specially designed for the elderly--- wisdom of the elderly body fall early warning and detection system, does not affect the normal life of the elderly, accurately distinguish the fall event from the daily life event, and in the event of a fall, timely send warning information to the children and call the police to contact the rescue, which plays an important role in improving the quality of life of the elderly and ensuring the stable development of our society.
