Description

Technical Field

[0001] The present invention relates to the field of smart homes, and in particular to a smart toilet seat detection method, a controller, a smart toilet, a computer-readable storage medium and a computer program product. Background Art

[0002] Smart toilets have basic functions such as warm air drying, buttocks cleaning, seat heating, wall moistening, and automatic flushing. In order to successfully enable the above functions of the smart toilet, the system needs to know whether there is a user sitting on the toilet seat. At present, most smart toilets on the market detect seat-taking by installing a capacitive sensing module on the left side of the toilet seat, and determine whether there is a user sitting by the voltage change of the capacitive sensing module. However, due to the small contact point of the capacitive sensing module, the reliability of this seat-taking detection method is low. For example, when the user is left-handed and lifts his left foot when cleaning his buttocks with a tissue, the capacitive sensing module will not detect the presence of the user, which will cause the system to misjudge that there is no user sitting; in addition, if the user's legs become numb after sitting for a long time and move their legs, the capacitive sensing module will repeatedly output low level / high level, and the system will repeatedly switch the seat / leave state, causing the basic functions of the smart toilet to fail to start or repeatedly trigger certain functions.

[0006] In one of the embodiments, when the current state of the smart toilet is the seated state, if the capacitive sensor continuously outputs a second preset level for a second preset time period, and the detection result of the microwave ranging module is that there is no moving object within a preset distance, the state of the smart toilet is switched to the unseated state.

[0007] In one of the embodiments, the smart toilet seat occupancy detection method also includes, when the current state of the smart toilet is the seated state, if the capacitive sensor continuously outputs the second preset level for a second preset time period, and the detection result of the microwave ranging module is that there is a moving object within a preset distance, then further determining whether the capacitive sensor continuously outputs the second preset level for a third preset time period, and if so, switching the state of the smart toilet to the unseated state.

[0024] like Figure 1 and Figure 2 As shown, one embodiment of the present invention provides a smart toilet seat detection method, the smart toilet seat detection method comprising: Acquiring the level of the capacitive sensor output; Obtaining a detection result of the microwave ranging module; When the current state of the smart toilet is the seat-off state, if the level output by the capacitive sensor is the first preset level, and the detection result of the microwave ranging module is that there is a moving object within the preset distance, the state of the smart toilet is switched to the seat-on state, and the smart toilet is controlled to perform a seat-on function, the seat-on function at least includes adjusting the seat ring temperature, the seat-off state refers to a state where no user is sitting on the seat ring, and the seat-on state refers to a state where a user is sitting on the seat ring; When the current state of the smart toilet is the seated state, if the level output by the capacitive sensor is a second preset level, and the detection result of the microwave ranging module is that there is no moving object within the preset distance, the state of the smart toilet is switched to the unseated state, and the smart toilet is controlled to perform an unseated function, and the unseated function at least includes flushing; The first preset level indicates that the capacitive sensor detects that an object falls on the seat ring, and the second preset level indicates that the capacitive sensor does not detect that an object falls on the seat ring.

[0025] In the current technology, since the contact point of the capacitive sensor is very small, the reliability of this seat detection method is low. Specific problems include: in the special environment of the bathroom, water droplets are easy to appear on the seat ring, and since water is also a conductor, when water droplets appear on the top surface of the seat ring corresponding to the installation position of the capacitor module, the capacitive sensor will detect that an object has fallen on the seat ring, causing the toilet to enter the seat state incorrectly. In the scheme of this embodiment, a capacitive sensor and a microwave ranging module are used for double detection to determine whether a user has sat on the toilet seat ring. When the level output by the capacitive sensor is the first preset level, that is, the capacitive sensor detects that an object has fallen on the seat ring, it will not immediately make the state of the smart toilet seat the seat state. It is also necessary to satisfy the microwave ranging module to detect a moving object within a preset distance before the state of the smart toilet seat is the seat state. The essence of the microwave module is to detect moving objects. For stationary objects such as water droplets, it will not affect its recognition accuracy. Therefore, this embodiment improves the accuracy of seat recognition. Another specific problem is that if the user's legs become numb after sitting for a long time and he moves his legs, the capacitive sensing module will repeatedly output the first preset level / the second preset level, and the system will repeatedly switch the sitting / leaving state, resulting in repeated triggering of the sitting and leaving functions. In the present embodiment, when the level output by the capacitive sensor is a high level, that is, when the capacitive sensor cannot detect that there is an object sitting on the seat ring, it is also necessary to satisfy the condition that the microwave detection module cannot detect any moving object within a preset distance before the smart toilet enters the leaving state. Since the user does not leave the smart toilet a certain distance when moving his legs, the microwave detection module will still detect the user at this time. Therefore, the smart toilet will not repeatedly switch between the sitting and leaving states, thereby not causing the repeated triggering of the sitting and leaving functions.

[0026] It should be noted that, in factory settings, the state of the smart toilet is initialized to an unseated state.

[0027] It should be noted that the present embodiment uses a microwave ranging module and a capacitive sensor for dual detection. The inventor has made in-depth considerations and the summary is as follows: If an infrared sensor is used in combination with a capacitive sensor for detection, although the infrared sensor can also detect whether there is a human body / object within a preset distance, considering the appearance of the toilet, the infrared sensor is generally installed inside the toilet. At this time, it is necessary to drill a hole in the ceramic body of the toilet to project the infrared light. This not only affects the overall appearance of the toilet, but also has high drilling costs, is difficult to install, and easily causes moisture to enter the toilet.

[0028] If the sensing area of ​​the capacitive sensor is increased, the sensing area needs to be increased to half the seat circle to deal with the situation that when the user is left-handed and lifts his left foot to clean his buttocks with a tissue, the capacitive sensing module cannot detect the user's presence, or the legs become numb after sitting for a long time and move the legs, resulting in repeated switching of sitting and leaving the seat. The essence of the capacitive module is to detect conductors, but the heating wire inside the seat ring for heating the seat ring is a conductor. If the sensing area of ​​the capacitive sensor is made to reach half the seat ring, there will be a certain degree of interference between the two. The heating wire affects the detection of the capacitive sensor, and the capacitive sensor is easy to affect the heating of the heating wire. In addition, this solution cannot solve the problem of misjudgment of sitting due to water droplets on the surface of the seat ring. If the microwave ranging module is used to directly replace the capacitive sensor, there are moving parts inside the smart toilet and in the environment where the smart toilet is used, such as the deodorizing fan, drying fan and other moving parts inside the smart toilet, and the bathroom where the toilet is used, such as the bathroom heater, heater and other electrical appliances, which will cause the microwave module to be inaccurate and lead to misjudgment. Therefore, it is not suitable to use the microwave ranging module to directly replace the capacitive sensor.

[0029] In this embodiment, a microwave ranging module is used to assist the capacitive sensor for detection. The microwave ranging module can be installed inside the toilet without opening a hole, and the microwave ranging module can be used to achieve other functions, including detecting the user approaching and automatically flipping the lid.

[0030] In some embodiments, when the current state of the smart toilet is the off-seat state, if the capacitive sensor continuously outputs a first preset level for a first preset time period, and the detection result of the microwave ranging module is that there is a moving object within a preset distance, the state of the smart toilet is switched to the seated state.

[0031] In some embodiments, when the current state of the smart toilet is the seated state, if the capacitive sensor continuously outputs a second preset level for a second preset time period, and the detection result of the microwave ranging module is that there is no moving object within a preset distance, the state of the smart toilet is switched to the unseated state.

[0032] In some embodiments, the smart toilet seat occupancy detection method also includes, when the current state of the smart toilet is the seated state, if the capacitive sensor continuously outputs the second preset level for a second preset time period, and the detection result of the microwave ranging module is that there is a moving object within a preset distance, then further determining whether the capacitive sensor continuously outputs the second preset level for a third preset time period, and if so, switching the state of the smart toilet to the unseated state.

[0033] Since there are moving parts inside the smart toilet and in the environment in which the smart toilet is used, such as the deodorizing fan, drying fan and other moving parts inside the smart toilet, and there are electrical appliances such as bathroom heaters and heaters in the place of use, the above reasons may cause the microwave module to always detect the presence of a human body within a preset distance, so that even if the capacitive sensor cannot detect that an object has fallen on the seat, there is actually no human body sitting on the seat, and the smart toilet cannot enter the accurate state, that is, the off-seat state. Therefore, timeout judgment protection is introduced in this embodiment. When the capacitive sensor cannot detect that an object has fallen on the seat for a period of time, even if the microwave ranging module always outputs shorter distance information, that is, always outputs the result of detecting a user within the preset distance, it will be forced to be judged as the off-seat state, making the entire system more reliable.

[0034] In some embodiments, the preset distance is 1 cm-40 cm.

[0035] In some embodiments, the third preset time length is 90s, the second preset time length is 2000ms, and the first preset time length is 500ms.
