    【 Introduction 】


    Smart home has become an important part of modern life, it not only enhances the comfort of living, but also brings convenience and security to our lives. In smart homes, the fall alarm radar module is widely used in residential areas for the elderly, medical institutions and living places for people with special needs. The module has the characteristics of high sensitivity, no dead Angle monitoring, remote alarm, etc., which can respond to fall events in time, reduce the risk of injury, and protect people's life safety. However, how to judge the fall alarm radar module is good or bad for users is very important. Therefore, in the form of video analysis, this article will show you how to accurately measure the performance of the fall alarm radar module radar module.

    First, the working principle of the fall alarm radar module radar module

    The fall warning radar module uses radar technology to detect fall events by monitoring and identifying human bodies in the living area. Its working principle is to use the weak electromagnetic wave emitted by the radar transmitter, receive the reflected electromagnetic wave through the receiver, and analyze the intensity, frequency and phase of the electromagnetic wave and other parameters to determine whether a fall event has occurred. By comparing with the pre-set threshold, when the situation is detected to exceed the set threshold, the fall alarm radar module will immediately trigger the alarm system to notify the relevant personnel in time.


    Second, the measurement of the fall alarm radar module radar module is good or bad


    Measuring the quality of the fall alarm radar module needs to consider the following aspects:


    Detection sensitivity: The fall alarm radar module must have high sensitivity to accurately detect the fall event. Therefore, the real fall situation should be simulated in the measurement, and the sensitivity of the module should be assessed by the alarm response time and accuracy rate.


    No-dead spot monitoring: A good fall warning radar module should be able to achieve no-dead spot monitoring, that is, fall events can be detected anywhere in the living area. During measurement, the monitoring coverage of the module can be evaluated by simulating falls in different scenarios and angles.


    Alarm system accuracy: The alarm system of the fall alarm radar module needs to have high accuracy and be able to distinguish between fall events and other ordinary activities. In the measurement, common activity situations in daily life can be simulated and their accuracy can be assessed by the alarm response of the module.


    Third, evaluate the performance of the fall alarm radar module radar module through video analysis


    In order to more intuitively evaluate the performance of the fall alarm radar module, we can record live video for analysis. The specific steps are as follows:


    Prepare video recording equipment: Use a high-definition camera or mobile phone to record video on site to ensure clarity and stability.


    Set different test scenarios: According to the actual needs and the design requirements of the fall alarm radar module, set different test scenarios, including different space sizes and angles.


    Simulate falls: Ask the tester to simulate falls, simulate falls in each test scenario, and ensure that the simulation process is consistent with the real situation.


    Video analysis and recording: According to the recorded video, whether the alarm response of the module is accurate by playback, and whether it can realize the requirements of no-dead Angle monitoring and high sensitivity.


    Through the above steps, we can evaluate the performance of the fall alarm radar module radar module and determine whether it meets our needs.


    【 Conclusion 】


    As an important safety device in smart home, the fall alarm radar module can effectively prevent the occurrence of fall events. In order to ensure its good working condition, we need to accurately measure the quality of the module. By understanding the working principle of the fall alarm radar module, selecting the measurement method reasonably, and using the video analysis to evaluate the performance, the performance of the fall alarm radar module can be judged more accurately. I hope this article has provided you with some useful references when choosing a fall alarm radar module.
