[0053] Also included is a control method, the control method comprising the following steps:

[0054] S01. When a guest steps on the welcome mat body 1, the gravity sensor 4 is subjected to pressure and the pressure is transmitted to the controller 2 in the form of an electrical signal. In this embodiment, multiple gravity sensors 4 are distributed in different positions. The gravity sensor 4 at the position where the guest steps on is subjected to pressure and sends an electrical signal to the controller 2, while the gravity sensor 4 that is not stepped on does not send a signal, thereby determining the guest's location.

[0055] S02. The controller 2 receives the signal from the gravity sensor 4 and processes it to determine whether the guest is heading "in" or "out". In the present embodiment, the controller 2 obtains the position of the gravity sensor 4 according to the number corresponding to the gravity sensor 4 that transmits the signal, and obtains the analysis result of whether the guest is walking in "in" or walking out "out" by matching the time sequence of the signals transmitted by multiple gravity sensors 4.

[0056] S03, the controller 2 controls the multiple light groups 5 to light up in sequence according to the guest's direction based on the judgment result, and the audio player 3 plays the corresponding audio; in this embodiment, the controller 2 issues a control instruction based on the judgment result, and controls the multiple light groups 5 to light up in sequence. Wherever the guest walks, the light group 5 at that position will be powered on and light up, and the audio player 3 plays the welcoming audio or the seeing-off audio.

[0057] S04, controller 2 sends a signal to the indoor speaker to control the indoor speaker to play audio according to the judgment result. If the result is "entry", controller 2 does not send a signal to the indoor speaker. In this embodiment, the volume of the audio player 3 is lower than the volume of the indoor speaker. First, the volume of the audio player 3 is too high to scare the guests. Second, the volume of the indoor speaker is higher so that the staff can hear it more easily and rush to provide services in time.

[0058] When a guest steps on the welcome mat, the gravity sensor 4 is subjected to pressure and transmits an electrical signal to the controller 2. After receiving the signal and analyzing and processing it, the controller 2 controls the light group 5 to light up as the guest walks, and the audio player 3 plays the corresponding audio. If the guest walks in from outside, the controller 2 also sends a signal to the indoor speaker to control the indoor speaker to play the audio, thereby reminding the store staff to respond in time to provide services for the guest. The multifunctional welcome mat senses the arrival of the guest by setting the gravity sensor 4, and controls the light group 5 to light up and the audio player 3 to play the audio through the controller 2. The light can improve the aesthetics of the welcome mat, and the audio can provide emotional value for the guest, making the guest feel warm and valued. In addition, the controller 2 can control the indoor speaker to play the audio, thereby reminding the staff to provide services for the guest in time, thereby improving the guest's consumption experience and the service quality of the merchant.

[0059] See also Figure 1 As shown, the welcome mat body 1 further includes an antibacterial layer 16, which is disposed between the waterproof layer 13 and the flame retardant layer 12. In this embodiment, the top surface of the antibacterial layer 16 is adhered to the bottom surface of the waterproof layer 13, and the bottom surface of the antibacterial layer 16 is adhered to the top surface of the flame retardant layer 12. Activated carbon is disposed inside the antibacterial layer 16, and the activated carbon can absorb gases such as formaldehyde in the air, which is environmentally friendly and healthy.

[0060] See also Figure 1 As shown, the welcome mat body 1 further includes a PVC board layer 17, which is disposed between the flame retardant layer 12 and the bottom plate 11. In this embodiment, the PVC board layer 17 is adhered to the bottom surface of the flame retardant layer 12 and covers the bottom plate 11.

[0061] See also Figure 4As shown, the controller 2 includes a signal receiving module 21, a processing module 22, a control module 23 and a signal transmission module 24. A plurality of gravity sensors 4 are respectively connected to the signal receiving module 21. The signal receiving module 21 is used to receive the electrical signal transmitted by the gravity sensor 4 and transmit it to the processing module 22. The signal receiving module 21 is connected to the processing module 22. The processing module 22 is used to match the signal sequence of the gravity sensor 4 with the light group 5 and analyze the direction of the guest. The processing module 22 is connected to the control module 23 and transmits the analysis result to the control module 23. The control module 23 is respectively connected to a plurality of light groups 5, the audio player 3 and the signal transmission module 24.

[0064] S102 : The signal receiving module 21 transmits the signal to the processing module 22 .

[0065] In this embodiment, the multiple gravity sensors 4 are subjected to pressure at different times as the guest walks, and thus the time at which the electrical signals are emitted is also different, resulting in a different time sequence for the signal receiving module 21 to receive the electrical signals and transmit them to the processing module 22, thereby determining the guest's walking direction.

[0066] See also Figures 5 and 6 As shown, step S02 of the control method includes the following steps:

[0067] S201, the processing module 22 compares and matches the positions of the gravity sensors 4 according to the sequence of the signals transmitted by the signal receiving module 21, thereby determining whether the guest is "entering" or "leaving";

[0068] S202, if the order in which the signal receiving module 21 receives signals corresponds to the position of the plurality of gravity sensors 4 being from far away from the door to near the door, that is, the first received electrical signal is sent by the gravity sensor 4 located far away from the door, then the judgment result is that the guest "enters the door";

[0069] S203, if the order in which the signal receiving module 21 receives signals corresponds to the position of the plurality of gravity sensors 4 being from close to the door to far away from the door, that is, the first received electrical signal is sent by the gravity sensor 4 located close to the door, then the judgment result is that the guest has "gone out";

[0070] S204 , the processing module 22 transmits the determination result to the control module 23 , and the control module 23 generates a control instruction and transmits it to the light group 5 , the audio player 3 and the signal transmission module 24 .

[0071] See also Figures 5 and 6 As shown, step S03 of the control method includes the following steps:

[0072] S301. When the judgment result is "enter the door", the control module 23 controls the multiple light groups 5 to be powered on and illuminated in sequence from far away from the door to close to the door, and controls the audio player 3 to play the welcoming words and related music; in this embodiment, the welcoming words corresponding to the guest "entering the door" are "Hello, welcome + business name", and the related music is selected in the style of light and cheerful songs.

[0073] S302, when the judgment result is "going out", the control module 23 controls the plurality of light groups 5 to be powered on and illuminated in sequence from the direction close to the door to the direction far from the door, and controls the audio player 3 to play the farewell speech and related music. In this embodiment, the farewell speech corresponding to the guest "going out" is "Have a nice day, welcome to visit next time + the name of the business", and the related music is light and cheerful music.

[0074] See also Figures 5 and 6 As shown, step S04 of the control method includes the following steps:

[0075] S401, when the judgment result is "entry", the control module 23 controls the signal transmission module 24 to transmit a signal to the indoor speaker;

[0076] S402. The indoor speaker receives the signal and plays a welcoming audio to remind the staff to arrive in time to provide relevant services to the guests; the welcoming audio of the speaker is consistent with the welcoming audio of the audio player 3, but the volume is set higher to remind the staff.

[0077] S403: When the judgment result is "going out", the information transmission module does not transmit signals to the indoor speakers.

[0078] See also Figure 2 As shown, the welcome mat body 1 is also provided with a power cord 18, which is electrically connected to an external power source and the controller 2, respectively, to power the gravity sensor 4, the controller 2, the audio player 3 and the light group 5.

[0079] Embodiment 2.

[0080] Specifically, multiple gravity sensors 4 are respectively connected to multiple light groups 5. When a certain gravity sensor 4 is subjected to pressure, the corresponding light group 5 is powered on and emits light. In this embodiment, multiple light groups 5 are not controlled by the controller 2, but are directly controlled by multiple gravity sensors 4. The connection principle can refer to the gravity lamp. When the guest steps on the welcome mat, the gravity sensor 4 under the foot position is subjected to pressure, triggering the movement of the heavy object to close the switch of the corresponding light group 5, and the light group 5 is powered on and emits light, so that the light will light up wherever the guest walks.

[0081] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0082] In summary, the present invention senses the arrival of guests by setting a gravity sensor 4, and controls the light group 5 to emit light and the audio player 3 to play audio through the controller 2. The light can improve the aesthetics of the welcome mat, and the audio can provide emotional value for the guests, making them feel warm and valued.
