Abstract
The utility model discloses a method and structure of a water closet for distinguishing urea and shit automatically by a pyroelectricity technology. The utility model comprises a pyroelectricity induced transmitting and receiving device and an eight-bit single chip computer. The utility model is characterized in that the I/O input end of the single chip computer is connected with the output end of the pyroelectricity induced transmitting and receiving device; the single chip computer can automatically recognize urea and shit according to the inducting time of the pyroelectricity of the human body, the critical time of the urea and the shit can be distinguished through programs and zone bits of the single chip computer, and meanwhile, different disinfecting time of a negative ion generator can be definitized according to the recognization of the urea and the shit. The utility model overcomes the defects that as a single gear type water closet can not automatically recognize the urea and the shit, the water resource can be wasted, and the disinfecting time of the negative iron can not be distinguished, the utility model provides the method and the structure to realize that the water closet can automatically recognize the urea and the shit through the pyroelectricity inducted technology, and the utility model can be used for a two-gear type water saving water closet and the water closet with a negative iron disinfecting function.
Description
Technical field the invention belongs to the application of singlechip technology in the sanitary equipment automation field.
Before background technology the invention applying date, known water closet relies on two buttons of size to distinguish excrements and supplies water, making troubles to the user also can't be according to changing the excrements crash time with the lavatory custom, the automatic disinfecting time of the adjusting when water closet of band chlorination equipment can not be distinguished excrements.
The purpose of summary of the invention the invention is exactly the defective that will overcome prior art, provides a kind of pyroelectric sensing technology to realize the automatic separating shit and urine structure of water closet.By definite crash time of distinguishing excrements of the identification of flag bit, when flag bit 00, be equivalent to and do not establish flag bit.Single-chip microcomputer is distinguished excrements by 6 liters of stool baths-3 liters of automatic water-supplies of urine bath according to the adjustable excrements crash time.Determine the disinfecting time of anion simultaneously according to the adjustable crash time.
The invention solves the technical scheme that its technical problem adopts: comprise pyroelectric sensing transmitting and receiving device, 8-bit microcontroller, the single-chip processor i/o input is connected with the output of pyroelectric sensing transmitting and receiving device, single-chip microcomputer is discerned excrements automatically according to the length of human body pyroelectricity sensitive time, by the crash time of SCM program and flag bit distinguished excrements, determine the different disinfecting time of negative ion generator simultaneously by the identification of excrements.The separation of determining excrements is a time constant, determines that by the ground connection of two bit flag positions and unsettled 4 kinds of combinations 00,01,10,11 separation of stool urine is 1 minute, 1.5 minutes, 2 minutes, 3 minutes; When flag bit is 00, is equivalent to and does not establish flag bit.Pyroelectricity pyroelectric sensing device is made up of probe, Fresnel lens, operational amplifier, voltage comparator, and its output is connected with one-chip machine port I/O (1), and the interval length of its secondary sensitive time is as the foundation of distinguishing excrements.Single chip machine controlling circuit can be provided with separately, also can with the one-chip machine common in the water closet control circuit, realize resource-sharing.
The beneficial effect of the invention is: the invention has overcome single grade of formula water closet waste water resource and the undistinguishable defective of anion disinfecting time that can not discern excrements automatically, provide a kind of and realize that by the pyroelectric sensing technology water closet discerns the method and structure of excrements automatically, be widely used in two grades of formula saving toilets and have the water closet of anion sterilizing function.
