It can be understood that the mat sensing illumination device disclosed in the present embodiment can be placed on the floor beside the user's bed or the floor in front of the door, as in the case of a conventional mat. Meanwhile, most users are more used to use weak light sources with light intensity such as desk lamps when needing to get out of bed temporarily at night, and the indoor lamps are not directly turned on, so that the rest of other people is prevented from being influenced, and eyes of people are prevented from being stimulated.

When a user needs to get out of the bed for temporary activities or enter a room at night, the user can directly get out of the bed or step into the room, and then step on the device, meanwhile, the area of the first induction area of the device can be far larger than that of the second induction area, that is, it is easier for the user to directly step on the mat 1 in the first sensing area, and the first soot sheet under the mat 1 slides slightly downward under the pressure (the second soot sheet remains unchanged), the first pressure sensor group 42 then detects the pedaled pressure, and transmits the acquired value to the controller 43, the controller 43 can obtain whether the current stepping is normal stepping according to the obtained pressure value (it can be determined according to a threshold, when the pressure value is smaller than the threshold, no reaction is made), and if the current stepping is normal stepping, the controller 43 can control the LED lamp 41 to start to illuminate. At this moment, the user can look over the position of second induction zone on step pad 1 with the help of the light of LED lamp 41 to whether the decision continues the illumination of control room lamp, still only need with the help of the light of LED lamp 41 can, need not to illuminate the room lamp.

Example 2

The difference between this embodiment and embodiment 1 is that, in this embodiment, the supporting board 2 and the receiving board 3 are replaced by adhesive layers, that is, the mat 1 is directly adhered to the sensing mat 4 through the adhesive layers.

The pasting layer can be made of the same material as the pasting material on the ash-pasting stepping pad on the market, namely, the dust can be pasted on the pasting layer, and the stepping pad 1 and the induction pad 4 can be pasted on the pasting layer. Similarly, the adhesive layer can be quickly separated from the pedal pad 1 and the induction pad 4, so that the adhesive layer can be conveniently replaced after dust is accumulated for a period of time.

Further, in this embodiment, a voice playing device is further installed inside the sensing pad 4, the voice playing device is electrically connected to the controller 43 and the power supply 45, and a protective shell is also installed above the voice playing device to prevent the sensing pad from being damaged by being stepped on; the controller 43 is further configured to determine a movement direction of the user on the intelligent mat according to data detected by the first pressure sensor group 42 and/or the second pressure sensor group 46 (that is, the user can determine the movement direction regardless of whether the user steps on the first sensing area, the second sensing area, or both the first sensing area and the second sensing area of the device), and control the voice playing device to play a designated prompt voice according to the movement direction.

Specifically, the controller 43 may store position coordinates or position relationships of the planar pressure sensors included in the first pressure sensor group 42 and/or the second pressure sensor group 46 in advance.

When the user steps on the device, the controller 43 records the position where the first pressure sensor group 42 and/or the second pressure sensor group 46 first detects the pressure as the initial position, i.e., the position coordinates of one or more planar pressure sensors that first detect the pressure;

then, the controller 43 records the position where the pressure is detected by the first pressure sensor group 42 and/or the second pressure sensor group 46 when the pressure disappears at the initial position as a target position, i.e. one or more new position coordinates;

at this time, the initial position points to the target position, i.e. the moving direction of the user on the intelligent mat.

It will be appreciated that a person's foot will typically land with the heel first and then the toe first when walking to the ground, and will lift the heel first and then the toe when lifting. That is, when the user steps on the device, the heel usually falls on the device first, and the toe leaves the device last, that is, at this moment, the falling position of the heel pointing to the falling position of the toe is the movement direction of the user.

It can also be understood that, when the initial position and the target position both include only one position coordinate, the moving direction is the position coordinate included by the initial position pointing to the target position; when the initial position and/or the target position include a plurality of position coordinates, the position coordinates at the farthest distance from each other may be taken as the representative coordinates of the initial position and the target position, and the representative coordinates selected by the initial position point to the representative coordinates selected by the target position, that is, the representative movement direction.

Further, when the controller 43 determines that the movement direction is the direction in which the user leaves the room, the controller 43 may control the voice playing device to play, please note the prompt words such as carrying personal belongings, and when the controller 43 determines that the movement direction is the direction in which the user enters the room, the controller 43 may control the voice playing device to play the prompt words such as welcoming home.

Further, the controller 43 can also compare the obtained movement direction with the vertical direction, when the included angle between the movement direction and the vertical direction is smaller than 30 degrees, the controller 43 can control the voice playing device to play the designated audio, and when the included angle between the movement direction and the vertical direction is larger than or equal to 30 degrees, the voice playing device does not work at this moment.

Similarly, the controller 43 can also control the working state of the voice playing device according to the data transmitted by the photosensitive sensor 44, so as to prevent sound pollution at night.

Furthermore, in this embodiment, the intelligent mat further comprises a power generation device, the power generation device is installed below the sensing mat, and the power generation device is electrically connected to the power supply.

The power generation device can be an existing power generation module installed under a power generation floor, namely when the device is stepped on, the power generation device generates current by cutting a magnetic induction line and charges the power supply 45.
