Description
Technical field
The utility model relates to kitchen guarding's technical field of electric appliances, particularly a kind of bath mat.
Background technology
Usually, user can cause falling because bathroom floor is wet and slippery when bathing, thus causes adverse consequences.
In correlation technique, judge whether user is in the state of falling by the pressure sensor be arranged in bath mat, such as, obtain the signal of the pressure sensor of multiple passage simultaneously, by carrying out FFT (FastFourierTransformation, Fast Fourier Transform (FFT)) to obtain pressure signal high frequency components to the pressure signal obtained, and judge whether user is in the state of falling according to the intensity of high fdrequency component, but there is certain defect in the method.
First, because the pressure signal obtained is analog quantity, usually containing high-frequency noise in pressure signal, therefore, in order to obtain high fdrequency component comparatively accurately, need the comparatively complicated pressure signal of design to become to send, hardware circuit and the software algorithm such as filtering conditioning and analog-to-digital conversion.
Second, when the high fdrequency component adopting FFT to obtain in pressure signal, in order to obtain good result of calculation, FFT has certain requirement to the sample frequency of pressure signal and sample length, and FFT itself also has certain amount of calculation, especially when signalling channel number is many, therefore, the processing speed of the method to main control chip has higher requirement, otherwise may cause calculate inaccurate or there is larger time delay.
3rd, usually judge whether user is in the state of falling according to the intensity of high fdrequency component, and stronger high fdrequency component generally only appears at the moment that user falls, therefore, cannot judge according to pressure signal again after user falls, thus add the reject rate that user falls.In addition, not every action of falling all can produce stronger high fdrequency component, but not action of falling can produce stronger high fdrequency component equally, such as, the movement of user's biped, and software algorithm cannot distinguish the source of high fdrequency component, therefore, the reject rate that user falls is too increased.
4th, because the setting of the frequency to high fdrequency component has subjective judgement, because this reducing the universality of the method.

The bath mat proposed according to the utility model embodiment is described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the bath mat according to the utility model embodiment, and Fig. 2 is the circuit diagram of the bath mat according to an embodiment of the present utility model.As shown in Figure 1 and Figure 2, this bath mat comprises body 10, multiple button and main control unit 20.
Wherein, multiple button is arranged on body 10 with a matrix type, and main control unit 20 is by scanning the state of multiple button to judge whether user is in the state of falling.
According to an embodiment of the present utility model, the corresponding switch of each button, each switch is connected with main control unit 20, wherein, whether main control unit 20 is triggered by detecting each switch the state scanning multiple button, and when the number of the switch be triggered is greater than predetermined number, main control unit 20 judges that user is in the state of falling.
Wherein, predetermined number can be demarcated according to actual conditions.
According to an embodiment of the present utility model, as shown in Figure 2, the line of matrix comprises N number of switch, and matrix column line comprises M switch, and wherein, M and N is the integer being greater than 1.
According to an embodiment of the present utility model, as shown in Figure 2, main control unit 20 comprises N number of scanning port and M detection port, wherein, in matrix, often one end of row switch is corresponding connected with M detection port after connecting together, in matrix, often the other end of row switch is corresponding with N number of scanning port after connecting together is connected, and in matrix, often one end of row switch is also connected to default power supply VCC respectively by resistance after connecting together.
Particularly, to fall the detection of state to simplify user, improving accuracy and the reliability of detection simultaneously, in embodiment of the present utility model, utilize the principle of matrix keyboard to fall the detection of state to realize user.
As shown in Figure 1, each circle represents a button, and the corresponding switch of each button, when user's biped stands on bath mat, the switch be under pressure is in on-state, and the switch be not under pressure is in off-state.Because the area that contacts to earth of the biped of people has certain limit, therefore, the switch number connected while correspondence also has certain limit, when the switch number connected is greater than predetermined number simultaneously, judgement user is in the state of falling by main control unit 20, otherwise user is in the state of not falling.
Specifically, as shown in Figure 2, N number of scanning port circulation output low level of main control unit 20 is to scan each switch, simultaneously, main control unit 20 detects the state of M detection port in real time, when the state of detection port is low level, represents that this switch is in on-state; When the state of detection port is high level, represent that this switch is in off-state.After main control unit 20 completes all key scans, main control unit 20 will count the number of the switch being in on-state, if the number being in the switch of on-state of statistics is greater than predetermined number, then main control unit 20 judges that user is in the state of falling; If the number being in the switch of on-state of statistics is less than or equal to predetermined number, then main control unit 20 judges that user is in the state of not falling.
As can be seen from Figure 2, the utility model adopts the principle of matrix keyboard to realize user and to fall the detection of state, with adopt pressure sensor to user fall state detection compared with, without the need to pressure signal transmission circuit and analog to digital conversion circuit, namely only need digital signal detection port can obtain the state of multiple button, make design more simple and reliable.
According to an embodiment of the present utility model, main control unit 20 also carries out radio communication with the controller (not specifically illustrating in figure) in water heater, main control unit 20 judge user send when being in and falling state control signal to controller with control water heater close.

According to a concrete example of the present utility model, as shown in Figure 3, the course of work of main control unit 20 comprises the following steps:
S101, power on beginning.
S102, obtains the number being in the switch of on-state.
S103, judges whether the number being in the switch of on-state is greater than predetermined number.If so, step S104 is performed; If not, step S105 is performed.
S104, user is in the state of falling.
S105, user falls, and returns step S102.
S106, closes water heater and sends alarm.
As can be seen from above-mentioned steps, the software algorithm of main control unit 20 is also fairly simple, and this software algorithm does not rely on the instantaneous variation of pressure signal when user falls, and has higher reliability and accuracy.
According to bath mat of the present utility model, multiple button is arranged on body with a matrix type, main control unit is by scanning the state of multiple button to judge whether user is in the state of falling, thus realize user and to fall the accurate judgement of state, and simplicity of design is reliable, cost compare is low, and versatility is stronger.
