[0039] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the present invention rather than all the structures are shown in the accompanying drawings.

[0040] Figure 1 It is a schematic structural diagram of a toilet provided by an embodiment of the present invention.

[0041] As Figure 1 shown, the toilet includes:

[0042] A base 110, a cover plate 120, at least one sensor 130, a wireless communication module 140, a control module 150, and an ink display screen 160.

[0043] Among them, the sensor 130 is used to collect data and send the sensor acquisition data obtained by the collection to the control module; the wireless communication module 140 is used to receive the control instruction sent by the terminal device, parse the control instruction to obtain function setting data, and send the function setting data to the control module; the control module 150 is used to receive the sensor acquisition data sent by the sensor and the function setting data sent by the wireless communication module, and control the ink display screen to display information according to the sensor acquisition data and the function setting data; the ink display screen is connected to the control module through a serial peripheral interface and is used to display information under the control of the control module.

[0044] The control module 150 can read the sensor acquisition data in the register of the sensor 130 through a bus protocol, such as temperature, humidity, etc., and perform data processing on the sensor acquisition data, such as parsing it into a readable value, converting the readable value into an actual physical quantity, and performing calibration to eliminate errors, etc. After converting the function setting data and the sensor acquisition data after data processing into display data in a format recognizable by the ink display screen (such as ASCII code, bitmap data), the display data is organized into frame data according to the screen display area (such as coordinates, pixel points), and a control instruction is formed according to the frame data and sent to the ink display screen, and the ink display screen displays information through the control instruction.

[0045] Both the function setting data and the sensor acquisition data belong to the status data of the toilet. In the working operation mode, a local refresh send instruction specifies the coordinate range of the refresh area. For example, the start and end addresses of the X / Y coordinates of the RAM are set through registers, and only the changed pixel data is written to the specified local area. The changed pixel data can be the difference data items that are different when compared with the status data of the previous moment adjacent to the first moment in the status data of the first moment. The local display area of the difference data items in the ink display screen is used as the specified refresh area. After sending the local refresh instruction, the screen directly updates the display information in the specified refresh area to the display information corresponding to the difference data items.

[0046] In the standby operation mode, according to the preset full-screen refresh cycle, the driving circuit of the ink display screen is turned on, and a full-screen refresh instruction is sent to the ink display screen. After the ink display screen performs the afterimage elimination and flicker at the preset number of times and preset frequency according to the full-screen refresh instruction, the status data and the preset background data in the full-screen refresh instruction are displayed. The status data for full-screen refresh can include all data items.

[0047] The control module 150 can be an MCU controller, and the wireless communication module 140 can adopt a Bluetooth / wifi module to communicate with the control module 150 through a serial port. Users can connect to the Bluetooth / wifi of the smart toilet through a terminal device and send control instructions to achieve remote control of the toilet, such as setting the seat temperature, turning on the flushing function, etc. The wireless communication module 140 analyzes the control instructions, obtains the function setting data and sends it to the control module 150. At the same time, the status data of the smart toilet can also be sent to the mobile phone APP through the Bluetooth / wifi module for display.

[0048] At least one sensor 130 can include an ambient temperature NTC (Negative Temperature Coefficient) sensor, a seat temperature NTC sensor, etc. For example, the ambient temperature NTC sensor monitors the ambient temperature around the toilet in real time and transmits the temperature data to the MCU controller. The MCU controller controls the seat heating function according to the preset temperature range. The seat temperature NTC sensor monitors the seat temperature in real time to ensure that the seat temperature remains within the comfortable range set by the user.

[0049] In the technical solution of this embodiment, a sensor is used to collect data and send the collected sensor data to a control module; a wireless communication module is used to receive a control instruction sent by a terminal device, parse the control instruction to obtain function setting data, and send the function setting data to the control module; the control module is used to receive the sensor data collected by the sensor and the function setting data sent by the wireless communication module, and control an ink display screen to display information according to the sensor data and the function setting data; the ink display screen is connected to the control module through a serial peripheral interface and is used to display information under the control of the control module. The technical solution of the embodiment of the present invention solves the problems of high display power consumption and eye damage of the current toilet display screen. The sensor and function setting information of the toilet can be displayed through the ink display screen, and the ink screen has good visibility in strong light, improving the display effect.

[0050] In an alternative embodiment, the support material of the ink display screen is a flexible substrate, and / or the thickness of the flexible substrate is between 0.3 mm and 0.5 mm.

[0051] The flexible substrate is, for example, polyimide, polyester, polyethylene naphthalate, and ultra-thin glass.

[0052] In an alternative embodiment, the ink display screen is mounted on the cover plate.

[0053] For example, on the inner or outer side of the cover plate. The ink display screen can also be mounted at other positions of the toilet.

[0054] In an alternative embodiment, the ink display screen is mounted on a groove of the cover plate, and / or a waterproof rubber strip is wrapped around the edge of the ink display screen.

[0055] The ink display screen is mounted on a groove of the cover plate, and the surface of the ink display screen is flush with the surface of the cover plate, so as to avoid damage to the ink display screen during the opening and closing of the cover plate. The edge of the ink display screen is waterproofed with a waterproof flexible sealant strip, such as silicone, to meet the IP67 waterproof standard and prevent water stains from seeping in.

[0056] Such as Figure 2 As shown, optionally, a groove is reserved on the surface of the cover plate 120 of the toilet, and the ink display screen 160 is embedded therein to ensure that the screen surface is flush with the cover plate. The ink display screen uses an ultra-thin flexible substrate as the support material, with a thickness of only 0.3 - 0.5 mm and an extremely light overall weight, which can be 50 - 100 g, and will not increase the burden on the toilet cover plate. And it has excellent flexibility, can adapt to the curved surface design of the toilet cover plate, and the bending radius of the flexible substrate can reach 10 mm to ensure that the screen is not damaged during the opening and closing of the cover plate.

[0057] In an alternative embodiment, the toilet further includes:

[0058] A detection module for detecting object activities within a preset area and sending the detection results to a control module, where the preset area is associated with the position of the toilet.

[0059] Correspondingly, the control module 150 is further configured to determine the working mode of the toilet according to the detection results, where the working mode includes a working operation mode and a standby operation mode.

[0060] Object activities can include the approach and departure of a human body. For example, Figure 8 As shown, the infrared sensor of the detection module is used to detect object activities. When a human body is detected approaching, it sends a signal to the MCU controller. The MCU controller determines the working mode as the working operation mode and controls the toilet lid to open automatically. When a human body is detected leaving, it determines the working mode of the toilet as the standby operation mode and controls the toilet lid to close automatically. When the toilet switches from the working operation mode to the standby operation mode, the control module 150 is further configured to turn off the driving circuit of the ink display screen.

[0061] It is also possible to detect information such as the motion posture of the human body through the radar sensor of the detection module, determine data for functions such as sedentary reminder, and send the data to the MCU controller. The MCU controller determines the display data according to the data for functions such as sedentary reminder.

[0062] In an alternative embodiment, the toilet further includes:

[0063] A flow rate acquisition module for acquiring water flow rate information and sending the water flow rate information to the control module 150.

[0064] Correspondingly, the control module 150 is further configured to determine the water flow temperature output by the water temperature control module according to the water flow rate information.

[0065] For example, Figure 3 As shown, the flow rate acquisition module uses an electromagnetic flowmeter to acquire water flow rate information through the principle of electromagnetic induction. The acquired analog signal is converted into a digital signal by a high-precision AD sampling chip and then transmitted to the MCU controller for acquiring the water flow rate information of the toilet, thereby controlling the magnitude of the water temperature output by the water temperature control module.

[0066] In an alternative embodiment, the toilet further includes:

[0067] A first power module for supplying power to the control module 150, the ink display screen wireless communication module, and at least one sensor through external electrical energy.

[0068] The first power module uses an AC-DC power conversion circuit to convert the commercial power into the DC voltages required by the system, such as 5V, 3.3V, 2.5V, etc., to supply power to various modules such as the MCU controller, the electronic ink screen display module, and various sensors.

[0069] In an alternative embodiment, the toilet further includes:

[0070] A second power module for powering the flushing module of the toilet through a backup battery in the event of a power outage of the first power module.

[0071] The second power module can be a power outage flushing module, including a backup battery and a control circuit. When a power outage of the mains is detected, the control circuit automatically switches to the backup battery power supply to provide power to the flushing motor of the toilet, realizing the flushing function during a power outage.

[0072] In an alternative embodiment, the control module 150 is further configured to perform data analysis on the function setting data sent by the wireless communication module to obtain setting preference data, and store the setting preference data in the storage module. The setting preference data is the setting data with the highest frequency in the function setting data; in the case where the toilet is in the working operation mode, obtain the setting preference data in the storage module, and adjust the function settings of the toilet according to the setting preference data.

[0073] As Figure 3 shown, the storage module adopts EEPROM (Electrically Erasable Programmable Read-Only Memory), and is connected to the MCU controller through the SPI interface. The control module 150, i.e., the MCU controller, stores the user's setting data with the highest frequency as the setting preference data, such as the setting preference of the seat ring temperature, the flushing mode preference, etc., and the historical monitoring data, such as the daily usage time, the weight change data, etc., into the EEPROM. When the user uses the intelligent toilet again, the MCU controller can read the user's setting preference data from the storage module and automatically adjust the function settings of the toilet to provide a personalized usage experience.

[0074] The edge of the ink display screen in this embodiment is wrapped with a sealing strip, and the material is thin and light, and the sealing effect is better. Compared with liquid crystal displays, etc., it is more suitable for humid environments. The ink display screen has the characteristics of low energy consumption and clear display in strong light, and it is not dazzling to look at the display screen when turning on the light at night, protecting eyesight.

[0075] Figure 4 FIG. is a flowchart of a method for controlling the display of an ink display screen provided by an embodiment of the present invention. This embodiment is applicable to the scenario of controlling the display of device information based on an ink display screen. This method can be executed by an ink display screen display control device, and this device can be implemented in a software and / or hardware manner and integrated into a computer device with application development functions.

[0076] As Figure 4 shown, the method for controlling the display of the ink display screen in this embodiment includes the following steps:

[0077] S410. When the device is in the working operation mode, collect the first state data of the device.

[0078] The device can be a home intelligent device, such as a smart toilet, a smart refrigerator, a smart air conditioner, a smart washing machine, etc. The working mode of the device can include a working operation mode and a standby operation mode. For example, when the smart refrigerator has not been opened for a long time, it will enter the standby operation mode. For the smart toilet, when the user does not use it, it will enter the standby operation mode, and when the user uses it, it will enter the working operation mode.

[0079] Smart home devices are usually equipped with a display screen, and the display screen needs to display the state data of the device. In this embodiment, in order to reduce the energy consumption of the home intelligent device, when the device is in the working operation mode, obtain the first state data of the device at the first moment, and perform display control according to the first state data to reduce the energy consumption in the standby operation state.

[0080] The first state data can be the sensor collection data and function setting data of the device at the first moment. The sensor collection data can be the data collected by the sensors installed on the device, including but not limited to temperature, humidity, etc.

[0081] The first state data can also be the time data associated with the first moment, such as the part represented by "X" in the display information "X year X month X day X week", or the prompt information generated by the device, such as the sedentary reminder information generated by the toilet, such as the part represented by "X" in the display information "Sedentary reminder: has been used for X minutes X hours X seconds".

[0082] S420. Determine the difference data items between the first state data and the second state data collected at the previous adjacent moment.

[0083] Among them, the second state data is the state data obtained at the previous moment adjacent to the first moment when the first state data is collected. The second state data at the previous moment adjacent to the first moment can be obtained at a preset storage location. Both the first state data and the second state data include the data content of at least one data item. For example, the number of minutes in the sedentary reminder, or the temperature value collected by the temperature sensor, etc. In this embodiment, not all the values of the first state data are refreshed and displayed, but the data items of the first state data that have changed compared with the data of the previous moment, that is, the difference data items, are determined, and display control is performed according to the difference data items.

[0084] S430. Based on the mapping relationship between the preset data items and the display area, determine the local display area of the difference data items in the ink display screen associated with the device.

[0085] The ink display screen is an electronic ink screen (E-Ink display). The differential data items may include one or more data items. Determining the local display area corresponding to the differential data items in the ink display screen associated with the device may be determined according to a preset mapping relationship between the data items and the display areas, that is, the mapping relationship between the attribute names of the preset data items and the display areas. The preset mapping relationship between the data items and the display areas may be determined by the preset display layout of the ink display screen. It can be understood that since the ink display screen contains multiple data items, the display area of the differential data items is a local display area in the ink display screen, and the shape may be rectangular.

[0086] S440. Convert the differential data items into display data in a first data format, and send the display data to the ink display screen, so that the ink display screen updates and displays the display data in the local display area.

[0087] The data items include the attributes and attribute values of the data. Converting the differential data items into display data in a first data format specifically means converting the data attribute values of the differential data items into display data in a first data format. The first data format is a numerical value in a recognizable format, and the first data format includes a bitmap data format and an ASCII code format. For example, convert data such as text and graphics into a bitmap format (such as each byte controlling 8 pixel points), and extract the font pattern data of the characters through a font library. When locally refreshing the numerical values of the differential data items, only the bitmap data in the changed area, that is, the local display area corresponding to the differential data items, is updated.

[0088] The ink display screen can erase the original image, activate the electrophoretic particles, and write a new image. It can adopt the mode of generating a picture font library. First, generate pictures of the sizes of the numbers 0-9, and then output the arrays of 0-9 through a picture conversion tool without including the C language functions of the header file. The picture conversion tool can visually adjust the data scanning method, grayscale (number of colors), image data arrangement method, brightness, contrast, etc. of the input image to obtain the bitmap or ASCII code of the numerical value. The bitmap or ASCII code of the local display area corresponding to the numerical value, as well as the coordinate information or pixel information of the local display area, can be sent to the ink display screen through the SPI interface to control the ink display screen to superimpose and display the updated numerical value, that is, the display data, on the basis of the original display screen.

[0089] In this embodiment, by locally refreshing the changed data, the power consumption of the ink display screen can be reduced, the number of full refreshes can be reduced, and the service life of the ink display screen can be improved. The efficient display of multiple device status information has strong scalability and is applicable to various smart home devices.

[0090] In the technical solution of this embodiment, when the device is in the working operation mode, the first state data of the device is collected; the difference data items between the first state data and the second state data collected at the previous adjacent moment are determined; based on the preset mapping relationship between the data items and the display areas, the local display areas of the difference data items in the ink display screen associated with the device are determined; the difference data items are converted into display data in the first data format, and the display data is sent to the ink display screen so that the ink display screen updates and displays the display data in the local display areas; wherein, the first data format includes the bitmap data format and the ASCII code format. The technical solution of the embodiment of the present invention solves the problems of high power consumption and eye damage of current device displays using displays such as LEDs. The state information of the device can be displayed through the ink display screen, with low local refresh power consumption in the working operation mode, good visibility under strong light, and improved display effect.

[0091] Figure 5 FIG. is a flowchart of a method for controlling an ink display screen provided by an embodiment of the present invention. This embodiment and the method for controlling an ink display screen in the above embodiment belong to the same inventive concept, and further describes the process of full-screen refresh in the standby mode. This method can be executed by an ink display screen control device, and this device can be implemented in a software and / or hardware manner and integrated in a computer device with application development functions.

[0092] As Figure 5 shown, the method for controlling an ink display screen in this embodiment includes the following steps:

[0093] S310. When the device is in the working operation mode, collect the first state data of the device;

[0094] S320. Determine the difference data items between the first state data and the second state data collected at the previous adjacent moment.

[0095] S330. Based on the preset mapping relationship between the data items and the display areas, determine the local display areas of the difference data items in the ink display screen associated with the device.

[0096] S340. Convert the difference data items into display data in the first data format, and send the display data to the ink display screen so that the ink display screen updates and displays the display data in the local display areas.

[0097] Wherein, the first data format includes the bitmap data format and the ASCII code format.

[0098] S350. When the device is in the standby operation mode, determine the full-screen refresh moment according to the preset full-screen refresh period.

[0099] The preset full-screen refresh period can be 24 hours, 12 hours, etc., and can be specifically set according to actual needs. When the device is in the standby operation mode and the user is not using it, there is no need to update the status data in real time. It is only necessary to perform a full-screen refresh according to the preset full-screen refresh period to eliminate the afterimage of the static display on the ink display screen.

[0100] S360. Determine the circuit startup time at a preset time interval adjacent to the full-screen refresh time before the full-screen refresh time, and turn on the driving circuit of the ink display screen at the circuit startup time.

[0101] In the standby operation mode, the driving circuit of the ink display screen is turned off. Therefore, it is necessary to turn on the driving circuit of the ink display screen at the circuit startup time at a preset time interval adjacent to the full-screen refresh time before the full-screen refresh time to prepare for the subsequent full-screen refresh. The preset time interval can be set according to actual needs.

[0102] S370. Collect the third status data of the device and determine the composite display data of the third status data and the preset background data.

[0103] The data items of the third status data can be the same as those of the first status data. The preset background data includes the background data under the current theme style and the fixed display content. The fixed display content is, for example, the part excluding "X" in the display information "Sedentary reminder: Have used X minutes X hours X seconds".

[0104] After determining the third status data, the third status data can be superimposed on the preset background data to obtain the composite display data of the third status data and the preset background data.

[0105] S380. Determine the full-screen refresh instruction according to the composite display data and the afterimage elimination and flicker parameters.

[0106] The afterimage elimination and flicker parameters can include the frequency and number of times of flicker for eliminating the afterimage. Determine the full-screen refresh instruction including the composite display data and the afterimage elimination and flicker parameters. The data format of the composite display data is the first data format recognizable by the ink display screen.

[0107] S390. Send the full-screen refresh instruction to the ink display screen so that the ink display screen performs afterimage elimination and flicker according to the afterimage elimination and flicker parameters, and updates and displays the composite display data to the full-screen display area of the ink display screen after the afterimage elimination and flicker.

[0108] The ink display screen performs afterimage elimination and flicker according to the afterimage elimination and flicker parameters in the full-screen refresh instruction, and updates and displays the composite display data in the full-screen refresh instruction to the full-screen display area of the ink display screen after the afterimage elimination and flicker.

[0109] In an alternative embodiment, when the device switches from the working operation mode to the standby operation mode, the driving circuit of the ink display screen is turned off.

[0110] When the device switches from the working operation mode to the standby operation mode, the driving circuit of the ink display screen is turned off to keep the ink display screen in static display. The electronic ink screen technology adopted in this embodiment has bistable characteristics, and the static display has zero power consumption, further reducing the energy consumption of the ink screen.

[0111] In an alternative embodiment, the device includes a toilet.

[0112] When the device is a toilet, the display function area of the ink display screen of the toilet may include a health parameter area, a basic parameter area, and a function adjustment area.

[0113] According to the function adjustment area and the operation inputs of the user-set parameters (such as water temperature, seat temperature, etc.) in the basic parameter area, such as terminal remote and key operation inputs, the function setting data is determined, and the display data of the function adjustment area and the basic parameter area is determined according to the function setting data.

[0114] According to the data collected by the sensor, the display data of the display area for displaying the sensor parameters in the basic parameter area is determined. The ink display screen of this embodiment has advantages such as high contrast, such as a contrast ratio of >1500:1, and a backlight-free design, and is particularly suitable for the bathroom scenario.

[0115] As Figure 6 shown, the display data of the ink display screen of the toilet includes ambient temperature, humidity, brightness adjustment status, weight monitoring data, sedentary reminder information, and time and date, etc. Figure 6 The boxed area is the partial display area for displaying the values of the display difference data items in the first state data.

[0116] As Figure 7 shown, in a specific information display example, the ink display screen is applied to the toilet. In the working operation mode, the IO control port and the SPI window of the ink display screen are initialized. The data collected by the sensor is processed, and it is determined that a refresh is required. The refresh data is displayed in the partial display area of the ink display screen.
