3. Basic environmental control based on human body: control and regulation of temperature/humidity/freshness.

4, sleep quality detection.

5. Whole house master control identification (lighting, security, etc.).

2. Application occasions

It is also suitable for nursing homes, intensive care units, etc.

3. Technical core

The invention provides a living body presence sensor, which includes a microwave generator and a microwave receiver. A mixed frequency detector and a signal processor, wherein the microwave generator can transmit in the detection space, and the microwave receiver can receive the corresponding microwave echoes, which are connected to the microwave generator and the microwave receiver, are set to mixed frequency detection signals, and output corresponding The signal processor is connected to the mixed frequency detector, and is set to select and amplify the primary detection wave signal output by the mixed frequency detector, output the secondary detection wave signal of a specific fluctuation frequency range, and the human body detector amplifies Action response signals within a specific frequency range to determine the presence of a human body (activity).

After more than ten years of research, human body sensing and heartbeat sensing technologies have reached the peak of the industry. Among them, the international patent of low-impedance antenna has solved the problems of poor environmental adaptability and easy interference of traditional microwave sensors. , security monitoring and other intelligent fields.

The living body presence sensor is the first to connect to PLC-IOT

Huawei released a whole-house smart ALLINONE solution, which can realize the interconnection of multi-module smart devices, which caused an uproar in the industry. During this period, it was the first to introduce a PLC IoT-compliant living presence sensor, a powerful addition to the smart home industry.

In the smart home and smart building industry, the lack of interconnection between devices and systems has long been criticized, greatly limiting the growth and development of the industry. The whole-house intelligent solution of living body presence sensor is based on PLC Internet of Things and home UWB backbone network, which enables the interconnection of lighting system, security system, air system, water system, music system, perception system and other intelligent devices in the whole house.

Based on microwave respiration detection technology, the living body presence sensor solves the problem that traditional sensors cannot detect static human bodies. Whether it is activities, meetings, reading, writing, rest or meditation, they can be detected by microwave sensors based on respiration detection. Presence sensing; integrated into different scenarios such as smart home, smart building, smart pension, security monitoring, etc., it can realize all manually triggered electronic devices such as lighting, curtains, security monitoring, energy management, heating, ventilation, air conditioning, etc. Truly safe, smart and energy efficient.

1. Detect living bodies to help home intelligence

After years of research and development and polishing, the living presence sensor product has been actively integrated into the smart home ecosystem since its release, and has joined hands with members of the Smart Home Alliance to jointly promote the application of microwave human body sensors in whole-house smart homes to achieve true presence sensing. Solve the pain points of the industry where the lights are out. In terms of communication protocol docking of intelligent building systems, it can not only connect traditional wired systems such as KNX, RS485, CAN, but also perfectly match with mainstream smart home protocols WiFi and Zigbee. It can be widely used in family residence, commercial office and other occasions.

2. Compared with traditional presence detection, living presence detection is really different

The living body presence sensor adopts the living body presence detection technology with independent intellectual property rights, combined with the low impedance antenna and the exclusive human body presence detection algorithm, and realizes the human body presence detection by detecting the expansion of the chest and abdomen when the human body is breathing. At the same time, through algorithms and microwave detection, airflow interference such as air conditioning and exhaust can be effectively avoided, and the existence of human respiration can be accurately identified.

The self-developed global patented low-impedance antenna technology can effectively filter the interference of external radio signals, creating an era in which microwave products pass the industry RED certification test in batches. In practical applications, there is no need to worry about 2.4G Bluetooth, 5.8G Wi-Fi.5G communication, RF and other wireless electromagnetic signals interfering with the normal operation of microwave induction.

3. Detect living bodies, true intelligence

The finished product detection technology of breathing and heartbeat radar sensor solves the problem that traditional sensors cannot detect the static human body. Whether it is activity, meeting, reading, writing, rest or static meditation, it can be detected by finished breathing and heartbeat radar sensor based on breathing detection. True presence detection. The microwave live sensor is perfectly integrated into different scenarios such as smart home, smart building, smart elderly care, security monitoring, etc., and can realize automatic control of home/building lighting. All manually triggered electronic devices such as curtains, security monitoring, energy management, heating, ventilation, air conditioning, etc., to achieve real safety, intelligence and energy saving.

Continuous innovation and more focus have always been our pursuit. In the follow-up breathing and heartbeat radar sensor products, we will continue to innovate, and cooperate with industry ecological partners to create more high-quality products and contribute to the smart home industry.
