Technical field

The utility model relates to sensor detecting field, is specially a kind of based on STC90C52AD monolithic processor controlled public lavatory automatic cleaning apparatus.

Background technology

Nowadays, dirty, random, the smelly problem of public lavatory is the thing that people complain always, similarly be colleges and universities, center, city, railway station and mall etc., lavatory in high like this crowd massing district, there will be ground unavoidably dirty and messy or give out unpleasant peculiar smell, although there is cleaner's timing to clear up, also only within one day, sweep two to three times.Because the flow of the people of public lavatory is large, also just cause the public lavatory most of the time to be all in the dirty and messy state in ground, and peculiar smell is heavier, allows the people gone to toilet feel extremely uncomfortable, also bring very large impact to civilized city.In order to solve dirty, random, the smelly situation in this public lavatory, also in order to people can have a comfortable lavatory environment, this practical invention devise a kind of safer, reliably, easily based on the public lavatory automatic cleaning apparatus that monolithic controls.

Utility model content

The utility model object is to provide a kind of STC90C52AD monolithic processor controlled public lavatory automatic cleaning apparatus, has solved the difficult problem in prior art reliability and security.

In order to achieve the above object, technical solution adopted in the utility model is: based on STC90C52AD monolithic processor controlled public lavatory automatic cleaning apparatus, it is characterized in that comprising: pyroelectric infrared sensor, normally closed electromagnetic water valve, single-chip microcomputer, A/D converter, ULN2003, solid-state relay, bellows and warning circuit, wherein warning circuit is sound circuit.Pyroelectric infrared sensor is connected with single-chip microcomputer by A/D converter, and single-chip microcomputer controls normally closed electromagnetic water valve and bellows action through driver ULN2003, and warning circuit is directly connected with single-chip microcomputer.Then can triggering voice circuit when control signal enters, alarming sound loudspeaker being sent pre-set, and also warning lamp also can become red by green.

Described based on STC90C52AD monolithic processor controlled public lavatory automatic cleaning apparatus, it is characterized in that: the human body infrared signal detected is converted to electric signal and is sent to A/D converter by described pyroelectric infrared sensor.

Described based on STC90C52AD monolithic processor controlled public lavatory automatic cleaning apparatus, it is characterized in that: described A/D converter converts the simulating signal collected to digital signal and is sent in single-chip microcomputer.

Described solid-state relay is two identical solid-state relays, respectively with being connected of normally closed electromagnetic water valve and bellows.

The core of described circuit of warning is lSD4003-04MP speech chip and warning lamp, and for controlling recording and playback, user typing can meet the warning sound oneself required, while alarming sound sound equipment rises, warning lamp also can become red.

Normally closed electromagnetic water valve and bellows are execution parts, and when the condition handled by single-chip microcomputer meets, then normally closed electromagnetic water valve is opened, and automatically closes when being timed to, and then bellows blow.

The beneficial effects of the utility model comprise:

1. pyroelectric infrared sensor can will detect and the infrared radiation received is transformed into faint voltage signal, backward outer output is amplified through the field effect transistor be contained in probe, and to human body radiation, there is unique identity, greatly enhance system sensitivity and accuracy, the effective guarantee safety of toileting persons.

2. solid-state relay is the contactless electronic beam switch with isolation features, the isolation of control end and load end is achieved with isolating device, power input is little, highly sensitive, control power is little, and Electro Magnetic Compatibility is good, and noise is low and frequency of operation is high, control system and main circuit are kept apart, improves the stability of system.

Accompanying drawing explanation

Fig. 1,2 is the utility model mechanical schematic diagram.

Wherein, 1 pyroelectric infrared sensor, 2 normally closed electromagnetic water valves, 3 bellows, 4,5 screen packs, 6 windows, 7 urinals, 8 closet stalls, 9 warning lamps, 10 alarming devices.

Fig. 3 is the utility model functional-block diagram.

Wherein, 1 pyroelectric infrared sensor, 2 single-chip microcomputers, 3ULN2003,4 solid-state relays, 5 normally closed electromagnetic water valves, 6 bellows, 7 warning circuits, 8 treatment circuits, 9 A/D converters.

Embodiment

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with Fig. 3, setting forth the utility model further.

Embodiment is as follows:

As shown in Figure 3, at official hour point, pyroelectric infrared sensor 1 will detect in lavatory that whether having the simulating signal of people to send into treatment circuit 8 processes, and the simulating signal after process is transformed into digital signal through A/D converter 9, then sends single-chip microcomputer 2 to and judge.If detecting has people to exist, single-chip microcomputer 2 does not perform any action, after time delay, then carries out detection judgement; If detect unmanned, single-chip microcomputer 2 is given an order, warning circuit 7 action, and voice start to report " cleaning, No Admittance ", and warning lamp 9 also starts to show blinking red lamp, thus has ensured the safety of toileting persons; Simultaneously single-chip microcomputer 2 controls normally closed electromagnetic water valve 5 and opens, start water horning ground, after a period of time, electromagnetic water valve 5 is closed, last single-chip microcomputer 2 control ULN20033 ' drives solid-state relay 4 ' action, bellows 6 start to blow out high wind, air-dry ground, and timing arrives, close bellows 6 and alarming device 7, people can enter lavatory.

The above, be case study on implementation of the present utility model, all should be encompassed in the utility model.
