Description

Smart bed based on IoT

The present invention relates to a smart bed, and more particularly, to a smart bed capable of detecting a user's location on a mattress based on IoT and providing a sleeping environment optimized for the user's sleep.

It is essential for humans to get a certain amount of sleep every day. Therefore, the bed performs an important function of relieving people's fatigue and providing the most comfortable place.

The conventional bed was developed with a focus on providing a comfortable place to lie down by installing a mattress on the top of the pedestal, but recently it has been used to provide the most comfortable space for watching TV or reading, as well as for rest or recovery from fatigue. Consumer demand is also growing.

In order to meet these consumer needs, recently, an electric bed with a folding backrest is being developed so that it is possible to comfortably sit on the bed, read a book or watch TV. Bed types are also being developed.

In the smart bed according to this embodiment, a plurality of pressure sensors 370 may be further disposed on the mattress 200 . The pressure sensor 370 is disposed on the top form 240 of the base form 210 , the side form 220 , the middle form 230 , and the top form 240 .

In addition, the pressure sensor 370 is disposed in the 1-1 zone 261, the 1-2 zone 262, the 2-1 zone 271, and the 2-2 zone 272, for each zone A plurality is placed.

The pressure sensor disposed in the 1-1 region 261 is referred to as a first pressure sensor 371 , the pressure sensor disposed in the 1-2 region 262 is referred to as a second pressure sensor 372 , and the second pressure sensor 372 is referred to as a second pressure sensor 372 . The pressure sensor disposed in the −1 zone 271 is called a third pressure sensor 373 , and the pressure sensor disposed in the 2-2 zone 272 is called a fourth pressure sensor 374 .

In order to more precisely detect the user's position through the minimum pressure sensor, the first pressure sensor 371 and the second pressure sensor 372 are arranged in a line parallel to the first center line C1, and the third pressure The sensor 373 and the fourth pressure sensor 374 are arranged in a line parallel to the first center line C1.

A plurality of the first pressure sensor 371, the second pressure sensor 372, the third pressure sensor 373, and the fourth pressure sensor 374 are respectively disposed and are spaced apart from each other in parallel with the second center line C2. placed in a row

Since the user does not often lie down parallel to the first center line C1, the control unit of the smart bed allows the user to use the 1-1 section 261, the 1-2 section 262, and the 2-1 section. The ventilation module 300 may be operated by determining which zone is located in the zone 271 or the 2-2 zone 272 .

The controller may be a processor that performs at least one operation indicated by at least one instruction stored in a memory. That is, the operation of the control unit is also interpreted as an operation performed by the processor.

For example, both the plurality of first pressure sensors 371 disposed in the 1-1 zone 261 and the plurality of second pressure sensors 372 disposed in the 1-2 zone 262 receive pressure When it is sensed, the user determines that it is disposed in the first zone 260 and adjusts the direction of the valve 335 to provide air only to the first zone 260 .

When pressure is sensed by both the plurality of third pressure sensors 373 disposed in the 2-1 region 271 and the plurality of fourth pressure sensors 374 disposed in the 2-2 region 272, When the user determines that it is disposed in the second region 270 , air may be provided only to the second region 270 by adjusting the direction of the valve 335 .

On the contrary, all of the plurality of first pressure sensors 371 disposed in the 1-1 zone 261 sense pressure, and at least any one of the 1-2 zone 262 and the 2-2 zone 262 . When a single pressure is sensed in one, it may be determined that the person is lying obliquely. In this case, air is provided only to the first region 260 where the user's head is located.

When a single number of pressures are sensed, it may be determined that the person is lying obliquely. In this case, air is provided only to the second region 270 where the user's head is located.

Through such control, it is possible to reduce the load on the ventilation module 300 by supplying air to only one of the first zone 260 and the second zone 270 and reduce power consumption.

It is possible to detect the temperature of the mattress 200 through the first temperature sensor 381 and the second temperature sensor 382 , and control the operation of the ventilation module 300 through the sensed temperature value.

For example, when the temperature value sensed by at least one of the first temperature sensor 381 and the second temperature sensor 382 exceeds 35 degrees Celsius, the ventilation module 300 is operated regardless of whether the user detects it or not. It can be operated to ventilate the air inside the mattress 200 .

In addition, it is possible to more precisely detect the user's position on the mattress 200 through the temperature value detected by the first temperature sensor 381 or the second temperature sensor 382 .

Specifically, the position of the user may be more precisely determined through the pressure value detected by the pressure sensor 370 and the temperature value detected by the temperature sensor 380 .

At least one of the first pressure sensor 371 , the second pressure sensor 372 , the third pressure sensor 373 , and the fourth pressure sensor 374 detects a pressure value exceeding the reference value, and the first temperature sensor When a temperature change exceeding the reference value occurs in at least one of 381 and the second temperature sensor 382, the user's location may be determined.

When the user lies on the mattress, the pressure value may be primarily sensed by the pressure sensor 370, and when a predetermined time elapses, the temperature of the mattress 200 may be locally increased due to the user's body temperature.

For example, when the first pressure sensor 371 detects a pressure value and the first temperature sensor 381 detects a temperature change, it may be determined that the user is located in the first zone 260 .

Contrary to this, when the first pressure sensor 371 detects a pressure value and the temperature change value of the first temperature sensor 381 is less than the reference value, it may be determined that the user is not located. In this case, it may be determined that a heavy object is placed on the mattress 200 .

In addition, when a pressure value is sensed by the first pressure sensor 371 and the second pressure sensor 372 , and a temperature change is detected only by the first temperature sensor 381 , the user is located in the first area 260 . It can be determined that, and only the first air channel 340 provides air.
