Millimeter wave radar sensor Price radar fall prevention device precision monitoring safety

I. Introduction

With the intensification of the aging population, the problem of elderly fall has been paid more and more attention by the society. Falling can not only cause physical damage, but also bring great psychological pressure to the elderly. Therefore, how to effectively monitor and prevent the elderly fall has become an urgent problem to be solved. Millimeter wave radar sensor, as a new sensing technology, has the characteristics of non-contact, high precision and high reliability, and is widely used in fall prevention devices. In this paper, the working principle, technical characteristics and application of millimeter wave radar sensor in fall prevention device are introduced in detail, and its market situation is analyzed to provide reference for relevant personnel.

Second, the technical analysis of millimeter wave radar sensor

Millimeter wave radar sensor is a sensor that uses millimeter wave to detect the target. Millimeter waves refer to electromagnetic waves with frequencies between 30GHz and 300GHz, with higher frequencies and shorter wavelengths. Millimeter wave radar sensor can obtain the distance, speed, Angle and other information of the target by transmitting millimeter wave and receiving the signal reflected back by the target. Compared with traditional infrared and ultrasonic sensors, millimeter wave radar sensor has the advantages of strong penetration, strong anti-interference ability and high precision. At the same time, the millimeter wave radar sensor also has the characteristics of all-weather and all-day, and can work stably in various environments.

Specifically, the working principle of millimeter-wave radar sensors can be divided into the following steps: First, the sensor transmits millimeter-wave signals; Second, the signal is reflected back to the target and received by the sensor; Then, the sensor calculates the distance, speed, Angle and other information of the target by analyzing the received signal; The information is transmitted to the host computer or microprocessor for processing.

Third, the application of millimeter wave radar sensor in the fall prevention device

Anti-fall device is used to monitor the elderly fall and timely alarm device. Due to the decline of the physical function of the elderly, it is easy to fall accidents, so the anti-fall device is of great significance in the daily life of the elderly. Millimeter wave radar sensors are widely used in fall prevention devices because of their non-contact and high precision. It can determine whether a fall occurs by monitoring the elderly's action trajectory and posture, and send an alarm signal in time.

Specifically, the application of millimeter wave radar sensors in fall prevention devices can be divided into the following steps: First, the sensor monitors the movement trajectory and posture of the elderly by transmitting millimeter wave signals; Secondly, through the analysis of the received signal, judge whether the fall accident occurs; Then, if there is a fall accident, the sensor will send an alarm signal in time; Finally, the alarm signal will be sent to the medical staff or relatives through wireless transmission, so that the rescue can be carried out in time.

Fourth, the price of millimeter wave radar sensor market analysis

With the aging of population and people's pursuit of healthy life, millimeter wave radar sensor is more and more widely used in fall prevention devices. At present, a variety of brands of millimeter wave radar sensors have appeared on the market, and the price varies depending on the brand, performance and other factors. In the future, with the continuous progress of technology and the continuous growth of market demand, the performance of millimeter wave radar sensors will be further improved, and the price will gradually decrease. At the same time, with the rapid development of smart home, smart medical and other fields, the application scenarios of millimeter wave radar sensors will also continue to expand.

Specifically, the factors that affect the price of millimeter wave radar sensors mainly have the following aspects: First, the performance parameters of the sensor are important factors that affect the price. The higher the performance parameters, the higher the price. Secondly, the brand and origin of the sensor will also affect the price. The prices of well-known brands and imported products are usually higher than those of ordinary brands and domestic products. Finally, market demand and supply will also have an impact on prices. If demand is greater than supply, prices may rise. Otherwise, it will decline.

Five, how to choose the right millimeter wave radar sensor

Choosing the right millimeter wave radar sensor requires consideration of several factors, including performance, price, brand, and service. First of all, sensors with appropriate performance parameters need to be selected according to actual needs. For example, the target size, distance, speed, etc. that need to be monitored need to be selected according to actual needs. Secondly, the price of the sensor and the balance of the budget need to be considered. Although high-performance sensors are more expensive, costs can be reduced by choosing the right product. In addition, brand and service are also important considerations. Well-known brands usually have better quality assurance and after-sales service, which can reduce maintenance costs and use risks in the later period. It is recommended to consider multiple factors and choose the MMwave radar sensor that best suits your needs.

Vi. Conclusion

This paper introduces the working principle, technical characteristics, application and market situation of millimeter wave radar sensor in fall prevention device. Through the analysis, it can be seen that the millimeter wave radar sensor has the characteristics of non-contact, high precision and high reliability, and is widely used in fall prevention devices. With the continuous progress of technology and the continuous growth of market demand, the performance of millimeter wave radar sensors will be further improved, and the price will be gradually reduced. At the same time, with the rapid development of smart home, smart medical and other fields, the application scenarios of millimeter wave radar sensors will also continue to expand. Therefore, choosing the appropriate millimeter wave radar sensor is of great significance to improve the quality of life of the elderly.
