Description
Technical field
The present invention relates to a kind of communal bathroom UNICOM's formula excrement groove intelligent water-saving control system and control method thereof, be used for UNICOM's formula excrement groove bath.
Background technology
The traditional Water flushing for cistern mode of communal bathroom UNICOM formula excrement groove is that water tap is transferred to certain size to the water tank water filling, and water tank water is the back auto-flushing completely, and the stool in the excrement groove is rushed in sewer.The problem of this mode is that the waste of water is very big, no matter whether the people is arranged, always it is in continuous bath, around the clock, unless you are the water tap pass.And another kind of bath mode is exactly by human inductor, as long as you enter the washroom, inductor injects a certain amount of water with regard to control electromagnetic valve to water tank, to certain person-time arrived after, water tank is just filled auto-flushing.Though this method has been saved a little water than regularly washing by water, its problem is:
1, can not distinguish the people who enters the washroom and whether need bath;
2, someone greatly after an action of the bowels for a long time the no one enter the washroom, or the people who enters the washroom is seldom, to such an extent as to long-time water tank can not be filled bath, causes stinking to high heaven, and influences air quality, aggravating working environment and public space.
Summary of the invention
Technical problem to be solved by this invention is a shortcoming big at tradition bath mode water supply volume, that can not in time wash by water, has utilized the Based Intelligent Control advantage of single chip microcomputer, and impacts flush is carried out control.
The present invention adopts concrete technical scheme as follows for solving the problems of the technologies described above:
A kind of communal bathroom intelligent water-saving control system comprises the full auto-flushing water tank of water, is used to control the electromagnetic valve of water tank water intake, also comprises water level sensor, door switch inductor, foot switch inductor, single-chip microcomputer; Wherein, level sensor is connected with single-chip microcomputer respectively with electromagnetic valve, is connected with single-chip microcomputer after door switch inductor and the parallel connection of foot switch inductor; Wherein:
Described water level sensor is positioned at water tank, is used to respond to cistern water level;
Described door switch inductor position is in each door lock place, position of squatting, and is used for the switch of induction door;
Described foot switch inductor is positioned at each position stance of squatting, and is used in the induction crouching position whether the people being arranged;
Described single-chip microcomputer is used to receive above-mentioned each inductor signal and control electromagnetic valve work.
Further, in the aforementioned communal bathroom intelligent water-saving control system, single-chip microcomputer is 8051 serial 89S52 single-chip microcomputers.
A kind of control method of communal bathroom intelligent water-saving control system comprises the steps:
Steps A is set the routine value of water volume in water tank, the minimum threshold of clock processing module, the max-thresholds of clock processing module respectively in single-chip microcomputer;
Step B, open the water filling in water tank of electromagnetic valve tap, when the water injection rate that detects water tank when water level sensor reached the conventional value of the water yield of setting of single-chip microcomputer, level sensor sent to single-chip microcomputer with detected water level signal, Single-chip Controlling is closed the electromagnetic valve tap, stops to the water tank water filling;
Step C senses signal when arbitrary crouching position door switch or foot switch inductor, and the clock processing module of single-chip microcomputer picks up counting:
C1, during the minimum threshold of setting less than single-chip microcomputer when the duration, single-chip microcomputer does not send command signal;
C2, when the duration surpasses minimum threshold that single-chip microcomputer sets and all and squats position door switch and the equal no signal of foot switch inductor, single-chip microcomputer sends command signal to electromagnetic valve, and the electromagnetic valve tap is opened to the water tank water filling, and water tank is opened automatically and washed by water when water is full;
C3, when the duration surpasses max-thresholds that single-chip microcomputer sets and arbitrary group and squats position door switch and foot switch inductor when still having signal, single-chip microcomputer sends command signal to electromagnetic valve, and the electromagnetic valve tap is opened to the water tank water filling, and water tank is opened automatically and washed by water when water is full;
Step D, whether repeating step B, C continue cycle detection and will wash by water.
Further, in the control method of aforementioned communal bathroom intelligent water-saving control system, the routine value of water volume in water tank is 95% of a water tank full water amount.
Further, in the control method of aforementioned communal bathroom intelligent water-saving control system, the minimum threshold that the clock processing module is set is 1 minute, and max-thresholds is 15 minutes.
The present invention adopts above technical scheme to have following technique effect: the present invention passes through Based Intelligent Control, realized as long as the people of stool has left squat over a pit to relieve oneself just bath and stool to squat over a pit to relieve oneself and have the people to continue more than 15 minutes just two kinds of bath standards of bath, thereby realized water conservation mode more and the more excellent control of air quality.
Description of drawings
Fig. 1 is a system hardware circuit logic diagram of the present invention.
Fig. 2 is a system of the present invention control flow chart.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described in further detail:
As shown in Figure 1, the inductor be made up of one or more groups door switch and foot switch of communal bathroom intelligent water-saving control system, single-chip microcomputer, electromagnetic valve, level sensor, the full auto-flushing water tank of water are formed.Each position of squatting is equipped with one group of inductor.When the people went to toilet stool, inductor was just given single-chip microcomputer signal, and single-chip microcomputer judges whether and will wash by water according to plug-in.
As shown in Figure 2, have the people to enter latrine pit if arbitrary crouching position door switch and foot switch are sensed signal instruction simultaneously, single-chip microcomputer picks up counting, and the minimum threshold of establishing the setting of clock processing module is 1 minute, and max-thresholds is 15 minutes, then:
If the duration, system thought that this is not a stool, but other things are arranged, and does not wash by water less than 1 minute;
If when surpassing after 1 minute the equal no signal of all squat position door switch and foot switchs, system thinks that stool finishes, and wash by water;
If arbitrary crouching position door switch and foot switch still have signal after 15 minutes, system sends instruction, wash by water.
As washing by water, single-chip microcomputer just sends instruction, opens the electromagnetic valve tap to the water tank water filling, and the water yield is about 5% of water tank total capacity, when when the full-water level with regard to auto-flushing.After water tank water had been put, water tank cut out automatically, and the electromagnetic valve tap continues to the water tank water filling, again rise to 95% place of water tank full-water level up to cistern water level, level sensor with detected have the water signal to give single-chip microcomputer after, single-chip microcomputer is just ordered, close electromagnetic valve, stop to the water tank water filling.As not bath, whether whether it just continues cycle detection has the people, will wash by water.
The used single-chip microcomputer of system is preferably 8051 serial 89S52 single-chip microcomputers.
Native system is by Based Intelligent Control, realized as long as the people of stool has left just squat over a pit to relieve oneself bath in time and stool to squat over a pit to relieve oneself and have the people to continue more than 15 minutes just two kinds of bath standards of bath, thereby realized water conservation mode more and to the more excellent control of air quality.
