Epson Infinity Sensing Smart Switch

Smart switches lead the smart home to take root in the land of the Divine Land. Over the past three years, they have gradually recognized the market. But it can be popularized in the market, and it is widely used in smart switches. Public entrances, corridors, toilets, parking lots, warehouses, and ordinary homes in the entrance, kitchen, living room, etc., are no longer dependent on mechanical switching of air-conditioning, lighting and other loads, but automatically determine whether someone needs a smart switch. The infrared human body sensor switch not only provides the intelligent convenience of people to light and avoids the trouble of finding switches in the dark, especially in unfamiliar public places, which provides a safe and comfortable protection; at the same time, it also meets the concept of energy saving, environmental protection and green intelligence. , Long lights, invalid air conditioning will no longer appear.

However, the design principle of the infrared human body sensor switch is very limited by the infrared pyroelectric sensor's sensing range because the infrared pyroelectric sensor senses the movement of the human body to control the switching action of the load. The sensing distances marked by various sensor switches on the market are uneven, ranging from 1.5 meters to 12 meters. There are rarely more than 5 meters in actual measurement, and distances of more than 5 meters are ideal for laboratory data. This requires a large range of intelligent sensor switch linkage functions for large spaces such as museums, exhibition halls, warehouses, and parking lots, which cannot be met, especially for large disinfection rooms, dangerous goods warehouses, and hazardous chemical sites in canteens, hospitals, and schools. Requires anyone to come from any direction, and immediately shut down all the disinfection lights and other harmful equipment. This distance is far from meeting the requirements.

With the commissioning of a large number of exhibition halls, hospitals and canteens in China, Epson Smart Switch has developed a human body sensing linkage switch system with no limit distance through RF technology. It has been successfully installed and used in many customers' specific locations, and has fully realized the customer. The expected goal has achieved very good results. It has once again innovated in the field of smart homes and has become the leader of new technologies in the industry.

Here we share the actual case with you:

First, large UV disinfection rooms in hospitals and canteens:

1. Project Source: UV disinfection lamps are currently one of the most common disinfection methods in hospitals, canteens, kindergartens, etc., but they also cause significant damage to the human body. Skin damage can cause damage to the skin, and weight can cause blindness. Therefore, all units are When using in a large range and in large doses, it is particularly prudent and often needs special caretaker to prevent accidental accidents caused by accidental entry.

2. Requirements: The client asks to install a circle of human body sensor switch outside the ultraviolet light disinfection zone of about 300 square meters, and turn off all the ultraviolet light disinfection lamps immediately no matter who they are in any direction. All UV lamps continue to work.

3. Solution: Due to the large size of the customer's disinfection area, it is not suitable to use a wall-type sensor switch. Therefore, April first selects its unique patented product, the ultra-thin oval-shaped ceiling sensor switch, according to its sensing distance, in terms of safety. A reasonable number of sensor switches are arranged outside the area, one of which is the master switch, which controls all the switches of the ultraviolet ray sterilizing lamp. The other switches communicate with each other through the RF signal. As soon as any one of the switches senses someone, the master switch is immediately notified to turn off all loads. Until the master switch detects that all sensor switches are unoccupied, it will delay the opening of all the disinfection lamps to ensure safe and reliable use.

Second, large exhibition hall:

1. Requirements: The hall is nearly a thousand square meters. There are 8 doors, 4 of which are connected to other small exhibition halls. It requires someone to enter from any door, and all the lights in the hall are automatically opened. When the visitors are close to each small exhibition hall, the corresponding small All lights in the exhibition hall are automatically opened. When no one is in the hall, all the lights in the hall are automatically closed. When no one is in the small exhibition hall, the lights in the corresponding small exhibition halls are automatically delayed and closed respectively. The delay time is set according to the area of ​​the exhibition hall. .

2. Solution: Adopt multiple human body sensor switches. Each sensor switch transmits signals through RF communication technology. According to the different positions, each sensor switch can communicate with one or more switches at different positions to achieve customer satisfaction. . In view of the long-distance transmission characteristics of the wireless transmission technology, not only the number of sensor switches required in the entire exhibition hall is drastically reduced, but also the control can be performed through the wall. Elegantly arranged on the top of the exhibition hall, the oval-shaped ceiling switch is not a beautiful landscape. The following picture shows a large-scale exhibition hall in Jiangsu.

For different areas of the exhibition hall and the needs of customers, Ai Purui gives two solutions. First, a master control switch is used. When people come to the hall, all the lights are on, and all lights are automatically extinguished. Second, multiple master switches are used respectively. Communicate with several sub-sensor switches to create a stage lighting effect. Where people go, only the nearby lights are on. After people leave, the next range of lights will turn on automatically, and the first set of lights will be automatically delayed and turned off. Stronger ability.
