Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

The paper supply device with the toilet seat occupation state automatic detection function provided by the embodiment of the invention is mainly applied to public sanitary places, and can automatically identify whether each toilet seat is occupied or not, so that the paper supply device can be used for toilet seat occupation state indication and plays a role in guiding users.

Fig. 1 is a schematic structural diagram of a paper feeding device with a toilet seat occupancy state automatic detection function according to an embodiment of the present invention, as shown in fig. 1, the paper feeding device includes: the device comprises a device shell 1, a paper feeding mechanism 2 arranged in the device shell 1, an ultrasonic sensor 3, a first pyroelectric sensor 4 and a signal transmission module (not shown in the figure);

specifically, the ultrasonic sensor 3 is horizontally disposed at a lower portion in the apparatus case 1, and an ultrasonic screen is provided on the apparatus case 1 in the ultrasonic wave emitting direction of the ultrasonic sensor 3.

The first pyroelectric sensor 4 is also horizontally disposed in the lower part of the device case, and a pyroelectric screen is provided on the device case 1 in front of the first pyroelectric sensor 4.

In the structure shown in fig. 1 in this example, the ultrasonic screen and the pyroelectric screen are combined into one screen 5, which covers both the ultrasonic sensor 3 and the first pyroelectric sensor 4.

The pyroelectric sensor is a sensor sensitive to temperature, when a human body enters a detection area, the human body is different from the ambient temperature, and the pyroelectric sensor monitors the corresponding output signal of the change of the temperature. The ultrasonic sensor converts an ultrasonic signal into other energy signals (usually, electric signals), and when the ultrasonic sensor touches impurities or interfaces, the ultrasonic sensor generates significant reflection to form a reflection echo, so that the displacement of an object is detected.

This application is used for the monitoring that the lavatory position occupied with pyroelectric sensor and ultrasonic sensor.

Specifically, the first pyroelectric sensor 4 is used for detecting the change of the ambient temperature around the paper supply device in the toilet, and when the temperature change exceeds a temperature change threshold value, the first pyroelectric sensor 4 outputs a first electric signal and sends the first electric signal to the ultrasonic sensor 3; wherein the temperature change threshold value can be set according to an empirical value.

The ultrasonic sensor 3 starts real-time monitoring of the obstacle according to the first electric signal, when the obstacle is monitored in the first distance range, the ultrasonic sensor 3 outputs a first state detection signal, and sends the first state detection signal and the device ID of the paper supply device to an external signal processing terminal through a signal transmission module. In which the device ID of the paper feeding device is recorded in advance in the signal transmission module, the first distance range is correlated with the accuracy of the ultrasonic sensor 3.

After the ultrasonic sensor 3 outputs a first state detection signal, when the ultrasonic sensor 3 does not monitor an obstacle within a first distance range within a first time period and the temperature change detected by the first pyroelectric sensor 4 does not exceed a temperature change threshold value, after the first time period, the ultrasonic sensor 3 outputs a second state detection signal and the first pyroelectric sensor 4 outputs a vacant state detection signal; the signal output module transmits the second state detection signal, the empty state detection signal, and the device ID of the paper feeding device to an external signal processing terminal.

Preferably, the paper supply device further includes a second pyroelectric sensor 6, the second pyroelectric sensor 6 is vertically disposed downward in the lower portion of the device case 1, and the bottom of the device case 1 further has a pyroelectric screen 7 disposed below the second pyroelectric sensor 6.

The function of second pyroelectric sensor 6 is the same with first pyroelectric sensor 4, increases the pyroelectric sensor of a vertical downward direction, is for increasing the sensitivity, especially to the shorter children of height, and the first pyroelectric sensor 4 that the level set up probably can not be sensitive senses, and the increase of second pyroelectric sensor 6 for the sensitivity of equipment increases.

The ultrasonic sensor 3, the first pyroelectric sensor 4 and the signal transmission module are connected through signal lines respectively; the second pyroelectric sensor 6, the ultrasonic sensor 3 and the signal transmission module are also connected through signal lines respectively.

The paper feeding device of the present invention further includes a power module (not shown in the figure) connected to the ultrasonic sensor 3, the first pyroelectric sensor 4, the second pyroelectric sensor 6 and the signal transmission module, respectively.

The paper supply device with the toilet seat occupation state automatic detection function can be used in the toilet seat occupation state detection system shown in figure 2.

In the detection system shown in fig. 2, a plurality of paper feeding devices 10, signal processing terminals 20, and display devices 30 are included; each paper feeding device 10 is installed in one toilet room; each of the sheet feeding devices 10 is constructed as shown in fig. 1 above. The signal transmission interaction between the paper feeding device 10 and the signal processing terminal 20 is preferably a wireless signal transmission method, and the signal interaction between the signal processing terminal 20 and the display device 30 can be realized by a wired or wireless signal transmission method.

With reference to fig. 1 and 2, the working process of the toilet seat occupancy state detection system can be as follows.

Each paper supply device 10 is installed in a toilet, the first pyroelectric sensor 4 and the second pyroelectric sensor 6 of each paper supply device 10 detect the change of the ambient temperature around the paper supply device 10 in the toilet, when a user walks into the toilet, the first pyroelectric sensor 4 and/or the second pyroelectric sensor 6 detect that the temperature change exceeds a temperature change threshold value, and the temperature change is sent to the ultrasonic sensor 3 by outputting a first electric signal;

the ultrasonic sensor 3 starts real-time monitoring of the obstacle according to the first electric signal, when the obstacle, i.e., the user, is monitored within the first distance range, the ultrasonic sensor 3 outputs a first state detection signal, and transmits the first state detection signal and the device ID of the paper feeding device 10 to the signal processing terminal 20 through the signal transmission module;

the signal processing terminal 20 determines the state of the toilet seat where the paper feeding device 10 is located as an occupied state according to the received device ID of the paper feeding device 10 and the first state detection signal, and outputs an occupied state signal to the display device 30 accordingly; the occupancy status signal comprises a first status indication parameter and a toilet ID;

the display device 30 analyzes the occupancy status signal, and outputs a status indication signal indicating the toilet seat where the paper feeding device 10 is located as a first status signal according to the toilet seat where the paper feeding device 10 is located and the toilet seat ID. In this example, the first status signal indicates an occupancy status, which may be indicated by a colored indicator light, or text, or other specific symbol. For example, in fig. 2, the 4 th toilet indicates that the toilet is in an occupied state through an indicator lamp.

After the ultrasonic sensor 3 outputs the first state detection signal, the ultrasonic sensor 3 and the first and second pyroelectric sensors 4 and 6 can also continuously monitor the signal change in the toilet. If a user walks out of a toilet, the situation that the ultrasonic sensor cannot continuously monitor the obstacle within the first distance range and the temperature change detected by the pyroelectric sensor does not exceed the temperature change threshold value can occur within the first time period. The first time period may be set according to an empirical value, for example, 5 seconds. The setting time cannot be too short to avoid false alarm caused by instant detection, and the setting time cannot be too long to avoid unnecessary toilet empty. When the above situation occurs, after the first duration, the ultrasonic sensor 3 outputs a second state detection signal, and the first pyroelectric sensor 4 and the second pyroelectric sensor 6 respectively output an empty state detection signal; the signal output module transmits the second state detection signal, the empty state detection signal, and the device ID of the paper feed device 10 to the signal processing terminal 20;

the signal processing terminal 20 determines the state of the toilet seat where the paper feeding device 1010 is located as the idle state based on the received device ID of the paper feeding device 10, the second state detection signal and the idle state detection signal, and outputs an idle state signal to the display device 30 accordingly; the vacant status signal comprises a second status indication parameter and a toilet ID;

the display device 30 analyzes the occupancy status signal, and outputs a status indication signal indicating the toilet seat where the paper feeding device 10 is located as a second status signal based on the toilet seat where the paper feeding device 10 is located and the toilet seat ID.

The display device 30 can be preferably arranged at an obvious position in a public washroom, and the signal output device for indicating the toilet position state on the display device 30 can be arranged and displayed according to the actual distribution condition of the toilet positions in the public washroom, so that a better prompt effect is generated for a user.

According to the paper supply device and the detection system with the toilet seat occupancy state automatic detection function, provided by the embodiment of the invention, whether a user is in the toilet seat or not is automatically identified through the pyroelectric sensor and the ultrasonic sensor in the paper supply device, so that the accurate real-time toilet seat occupancy state can be obtained, and the user waiting for using the toilet seat can accurately know the toilet seat state through the reasonably arranged display output device, so that the effects of effectively dredging the user and reducing the waiting time of the user are achieved.
