The information accurately obtains the health status of the human body. The above-mentioned various detection modules are divided into three categories and introduced respectively:
[0050] 1. ECG detection module, blood pressure detection module, heart rate detection module
[0051] Because the state of exertion of various parts of the body will be different from usual when a person is going to the toilet, the heart state, blood pressure and heart rate of the person will be different from the usual situation when going to the toilet. Therefore, the electrocardiogram detection The module, the blood pressure detection module and the heart rate detection module can detect various physiological parameters of the human body during the process of going to the toilet. Specifically, the installation positions of the electrocardiogram detection module, blood pressure detection module and heart rate detection module on the toilet will directly affect their detection accuracy.

Through the above two installation methods, it can accurately detect the heart state, blood pressure and heart rate of a person when going to the toilet.
[0052] 2. Sensor
[0053] In the smart toilet provided by the present invention, the following types of sensors can also be installed: optical sensors and/or AC/DC impedance sensors and/or turbidity sensors. Wherein, the optical sensor includes: one or more of an optical reflection sensor, an optical scattering sensor and an optical transmission sensor. The installation position of the optical sensor also affects its detection accuracy. In the present invention, the image acquisition sensor in the optical sensor, such as a camera, can be installed on the inner wall of the toilet base, and is located above the water surface of the buffer water inside the toilet, and the lens of the camera can be aligned with the center of the buffer water inside the toilet . And other optical sensors in the present invention, for example: optical transmission sensor, comprise: sending end and receiving end, and its working principle is: the light that sending end sends out, the transmission light that obtains after being transmitted by human excrement is received by receiving end, receives The end judges the particle size, density and other information of human excrement by analyzing the light intensity and direction of the transmitted light. Therefore, for a sensor with this working principle, the sensor needs to be installed on the inner wall of the toilet base, and located below the water surface of the buffer water inside the toilet, and the direction of the light emitted by the sensor can be aligned with the center of the buffer water inside the toilet .
[0054] 3. Urine sugar detection module
[0055] The urine sugar detection module includes two types: (1) urine sugar test paper method: specifically includes: urine sugar test paper and a rotating device supporting the urine sugar test paper. (2) Method for detecting urine sugar with AC/DC impedance sensor.
[0056] The human excrement sensing module provided by the present invention can sense human excrement in two ways: (1) Infrared sensor: the infrared sensor is installed on the upper part of the inner wall of the toilet base. (2) Pressure sensor: The pressure sensor is installed at the intersection between the toilet base and the toilet seat.
[0057] Using the above-mentioned device, the present invention provides a method for detecting human health status, comprising the following steps:
[0058] S1, when the human excrement sensing module senses that there will be and/or existing excrement inside the smart toilet, send a start signal to the single-chip microcomputer;
[0059] Specifically, the pressure sensor installed between the toilet seat and the toilet seat judges whether the sensed pressure signal is within a preset range, and if the judgment result is yes, there will be a excrement. For example: the preset pressure signal range can be the pressure signal range from the weight of a child to the weight of an adult. Through this method, it can be judged that the person has sat on the smart toilet. Therefore, it can be speculated that the smart toilet will There is excrement.
[0060] The human excrement sensing module senses that the existing excrement inside the smart toilet is specifically:
[0061] The infrared sensor installed on the upper part of the inner wall of the toilet base detects the internal space of the intelligent toilet, and when foreign matter is detected in the internal space of the intelligent toilet, there is excrement inside the intelligent toilet.
[0062] S2. When the single-chip microcomputer receives the start signal, the single-chip microcomputer sends an opening signal to the switch of the human physiological parameter detection module according to a preset delay time, and then starts the human physiological parameter detection module;
[0063] S3, the human body physiological parameter detection module collects the physiological parameters of the human body;
[0064] Specifically include: the optical sensor collects images of human excrement and/or the optical reflection information of human excrement; and/or the electrocardiogram detection module collects the electrocardiogram information when the human body goes to the toilet; and/or the blood pressure detection module collects the blood pressure when the human body goes to the toilet information; and/or the heart rate detection module collects the heart rate information when the human body goes to the toilet; and/or the urine sugar detection module collects the urine sugar information when the human body goes to the toilet.
[0065] The urine sugar detection module collects the urine sugar information when the human body goes to the toilet, specifically:
[0066] When the rotating device supporting the dry urine sugar test paper receives the start signal from the single-chip microcomputer, the timer built in the single-chip microcomputer is triggered to start counting, and at the same time, the rotating device rotates at a preset angle to drive the dried urine sugar The test paper enters the buffer water located inside the smart toilet, and at this time, the dry urine sugar test paper is wetted by the buffer water to obtain a wet urine sugar test paper;
[0067] The wet urine sugar test paper is in contact with the urine, and when the timing of the timer reaches the preset time, the optical sensor is triggered to collect the image of the wet urine sugar test paper in contact with the urine, and the The image information is sent to the single chip microcomputer. That is to say, the urine sugar test paper is wrapped around the rotating device in a non-use state and is in a dry state; only when the urine sugar test paper needs to be used, a certain length of urine sugar test paper is put into the buffer water.
[0068] In addition, in the present invention, in order to improve the detection accuracy, the turbidity sensor can pre-judge the turbidity of human excrement, only when the turbidity is low, the optical sensor is activated to collect the image of the wet urine sugar test paper or the AC/DC impedance sensor Collect urine sugar information of human excretion, because urine sugar detection is more sensitive and reliable only when the turbidity is low, preferably when there is only liquid excretion and no solid excretion. Specifically, it includes: the turbidity sensor detects the turbidity information of human excrement, and sends the detected turbidity information to the single-chip microcomputer; only when the single-chip microcomputer confirms that the turbidity information is lower than the preset turbidity information , to send an activation signal to the optical sensor and/or the AC/DC impedance sensor.
