It is protruded into excreta aqueous solution (1) to the end of inner tube (9) lower end out, then the second microcontroller (31) sends out trigger signal
To occult blood detection module (2)；
Step 3: occult blood detection module (2) receives the trigger signal sent from the second microcontroller (31)；
Step 4: trigger signal elder generation activating light source (21), light source (21) launch the light beam of specific wavelength again, and light beam injects horse again
In excreta aqueous solution (1) in bucket (5) and backlight is generated, then backlight injects optical sensor (22), optical sensing
Device (22) receives backlight and the backlight received is transmitted to the first microcontroller (23)；
Step 5: the first microcontroller (23) first carries out signal to the optical signal of backlight and is converted into electric signal, then by electric signal
It is converted into digital signal, then data processing is carried out to digital signal, then whether judge in excreta containing latent according to data processing
Blood signal simultaneously obtains testing result, then will test result and is sent to intelligent water toilet pan (3)；
Step 6: the second microcontroller (31), which receives testing result signal and will test consequential signal, passes through display interface (34)
It is sent to display device, display device will test to be come out as the result is shown, to terminate to detect.
