What needs to be understood here is: the electrocardiogram is the bioelectric change process of the heart in each exercise cycle. It is a manifestation of the reciprocating activity of the heart, and it is the process of excitement from the pace point-atrium-ventricle. The electrocardiogram examination is of great significance to the diagnosis of cardiovascular diseases: it has important diagnostic value for arrhythmia and conduction disorders; it is of great help in the diagnosis of myocarditis, coronary artery insufficiency and pericarditis. The electrocardiogram examination will be used to check various diseases such as arrhythmia, ventricular atrial hypertrophy, myocardial infarction, arrhythmia, myocardial ischemia, etc. It can reflect the degree and development process of myocardial damage and the functional structure of the atria and ventricles. In addition, through the ECG examination, it can be found that Brugada syndrome, long QT and short QT syndrome cannot be found by other examinations. For example, the heart rate is calculated based on the ECG signal: the number of times the atrium beats per minute is called the atrial rate, and the number of beats per minute of the ventricle is called the ventricular rate. The heart rate calculated by the electrocardiogram actually refers to the number of times the heart is electrically excited per minute. Under normal circumstances, each QRS wave on the ECG represents a heartbeat. Converting the number of heartbeats within a certain period of time to the number of heartbeats per minute is the heart rate; therefore, modern medical technology can be used to obtain the physical sign data of many people through the use of electrocardiogram signals.

The above can calculate the PBF body fat rate and PBW body water rate of the measurer based on gender, height, and weight, combined with the BMI index to determine the degree of obesity, and the possible risk of chronic diseases; combined with the heart function, respiratory function and fatigue level, determine the work status of the tester , Provide reminder information based on the health assessment model and the risk of chronic diseases.

When the user is on the toilet seat body 1, the PPG module 23 installed on the upper end surface of the toilet seat body 1 will automatically collect the pulse wave signal of the user, and amplify and filter the pulse wave signal to the processor 224. The processor 224 performs signal processing on the pulse wave signal (including extracting the characteristic signal, processing by de-interference, analysis, synthesis, transformation, and calculation to obtain the required characteristic signal), and then passes the above-mentioned characteristic signal through the main controller 3.

As shown in the figure..., regarding the principle of the PPG module 23: the principle that the photoelectric sensing element absorbs the light energy during the heart rate detection, records the signal detected by the change of the blood flow in the blood vessel by the light. The blood flow rate changes with the beating of the heart. The photoelectric sensing element will change with the contraction and expansion of the blood vessel to cause the sensor to produce a change in brightness or light reflection. At present, there are two types of sensing in the industry. The detectors can be used to present, one is a photoelectric secondary body sensor, and the other is a complementary metal oxide semiconductor sensor, both of which can be used to measure blood changes in the subcutaneous tissue; this embodiment uses a photoelectric secondary body sensor.

Further, the processor 224 and the main controller 3 communicate with each other through a universal asynchronous transmitter-receiver 5. The Universal Asynchronous Receiver Transmitter 5 is usually called UART, and the use of the Universal Asynchronous Receiver Transmitter 5 can make the communication speed higher and the transmission security higher.

In addition, the processor 224 is also connected to a wireless communication module 6, and the processor 224 is connected to the mobile terminal 7 through the wireless communication module 6. The wireless communication module 6 is connected with the mobile terminal 7 to send the physical sign data to the mobile terminal 7 for viewing and recording by the user and the user's family.
