Fall-down alarm equipment and method

Abstract

The application discloses fall-down alarm equipment and method, and relates to the technical field of the radar detection. The fall-down alarm equipment comprises an equipment controller, and a horizontal rotating motor is arranged on the equipment controller, a vertical rotating motor is fixedly arranged at a rotating end of the horizontal rotating motor, a laser sensor is arranged on the rotating end of the vertical rotating motor, and the laser sensor is electrically connected with the equipment controller; alarm equipment is further arranged on the equipment controller; and the alarm equipment is electrically connected with the equipment controller. The horizontal rotating motor, the vertical rotating motor and the laser sensor form a three-dimensional laser radar, thereby realizing the collection of three-dimensional point cloud data, and then the dynamic data point of the corresponding personnel is determined through the equipment controller; and a personnel state is judged according to the point variation quantity of the dynamic data point. if judging that the personnel falls down, the alarm equipment is controlled to give an alarm and notify other people that the personnelfalls down; and meanwhile, the boundedness that the alarm can be given only when the traditional wearable equipment or sensor is carried on the body and the phenomenon that video type alarm is easilyinvolved to the privacy are solved.

Description

technical field [0001] The present application relates to the technical field of radar detection, in particular to a fall alarm device and method. Background technique [0002] Cardiovascular and cerebrovascular diseases often suffered by the elderly, such as hypertension, coronary heart disease, cerebral arteriosclerosis, vertebrobasilar artery insufficiency, cardiac rhythm disorder, etc., can lead to transient cerebral insufficiency, resulting in cerebral ischemia and hypoxia, which makes the patient suddenly Brain dysfunction occurs, loss of consciousness occurs and faints. How to know in time that the elderly fell is particularly important, so that the elderly can be treated in time. [0003] At present, there are two main types of fall alarm devices for the elderly on the market. One is wearable (patents: CN105726034B, CN103854440A, CN105469546B). The elderly can judge the fall by wearing a bracelet or the corresponding fall alarm sensor. Class judgment relies on the ...

Problems solved by technology

[0004] However, for wearable alarm devices, it is necessary to carry the equipment at all times. For home use, especially for the elderly, it is often the case that they forget to bring it or charge it.

The other is based on video analysis. This method has the disadvantage of low recognition rate. At the same time, because it involves the privacy of personal life, many people are unwilling to install it, and many places are not suitable for installation.
