The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
A kind of medicinal intelligent sewage disposer of the utility model mainly comprises sewage disposer and lid, wherein establishes motor 9 and control circuit (see figure 1) thereof in the sewage disposer, and lid can be opened and be fastened on the sewage disposer under the driving of motor 9.Motor 9 is DC machine, is provided with one on it and can drives the gear that lid rotates.For guarantee that human body does not contact with lid with sewage disposer when losing rubbish, control circuit adopts the mode of infrared induction that motor 9 is controlled.Just drive motor 9 is opened lid when control circuit is sensed the human body approach sewage disposer.For this reason, sewage disposer is provided with the induction window of transparent or opening near the position of dog-house, and the infrared inductor of control circuit is pressed close to induction and passed setting.
Among the embodiment as shown in Figure 1, the control circuit of motor 9 comprises infra-ray sensing detector, the first amplifying circuit, negative circuit, governor circuit, the second amplifying circuit, photoelectric isolating circuit and motorized motions circuit.
Wherein, the infrared signal that the infra-ray sensing detector sends for detection of human body when it has detected human body approach, when for example having human body to occur, is exported induced signal in induction window 15 to 30 cm range.In the present embodiment, the infra-ray sensing detector has adopted infrared thermal release electric process chip BISS0001, it is that a transducing signal with superior performance is processed integrated circuit, and it is equipped with the pyroelectric infrared switch of pyroelectric infrared sensor and a small amount of outward element formation passive type.It can open the devices such as all kinds of filament lamp, fluorescent lamp, buzzer phone, automatically-controlled door, electric fan, dryer and automatic hand washer automatically fast, be specially adapted to the sensitizing ranges such as passageway, corridor of enterprise, hotel, market, storehouse and family, or be used for automatic light, illumination and the warning of safety zone.When people's hand or object proximity dog-house (should feel window) approximately during 15cm-30cm, the infra-ray sensing detector will produce a high level signal (for example 3V), nobody near the time, the output low level signal.
As depicted in figs. 1 and 2, what the first amplifying circuit adopted is a NPN triode 1, is used for the induced signal of infrared detection device is amplified.The base stage of aerotron 1 links to each other with terminal CON1, and terminal CON1 links to each other with the mouth of infra-ray sensing detector.The collecting electrode of aerotron 1 and feed circuit mouth VCC(5V) link to each other, its emitter links to each other with negative circuit.
What negative circuit adopted is a signal negate chip 2, is used for the induced signal that amplifies is carried out negate, realizes the conversion of high-low level.
What governor circuit mainly adopted is micro controller system 3, and model can be STC89C52, is used for according to anti-phase induced signal output pwm signal.Especially, in the present embodiment, when governor circuit after the schedule time that induced signal disappears, for example again export the PWM reverse signal 3 seconds, thereby guarantee after rubbish enters sewage disposer, just to cover lid.The mouth of negative circuit links to each other with the interrupting input mouth INT0 of micro controller system 3.Micro controller system 3 is by its mouth P00 and two pwm control signals of P01 output.
What the second amplifying circuit mainly adopted is that two PNP triodes 4,5 pairs of these pwm signals amplify processing.Aerotron 4,5 base stage link to each other with P01 with the mouth P00 of micro controller system 3 respectively, and its emitter meets feed circuit mouth VCC, and its collecting electrode connects respectively two input ends of photoelectric isolating circuit.
Photoelectric isolating circuit has adopted photoelectric isolated chip 6,7, and model can be EL817, is used for the pwm signal after amplifying is carried out the photoelectricity isolation and is transferred to the motorized motions circuit.Photoelectric isolated chip 6,7 input end link to each other the input end of output termination motorized motions circuit with aerotron 4 with 5 collecting electrode respectively.
The motorized motions circuit has adopted chip L9110, is used for according to the pwm signal of receiving motor being driven.In the present embodiment, the motorized motions circuit is the special-purpose integrated device device of two passage push-pull type power gains of control and drive motor design, and discrete circuitry is integrated among the monolithic IC, makes the peripheral components cost, the whole aircraft reliability raising.This chip has the input of the compatible level of two TTL/CMOS, has good anti-interference resistance; Forward and reverse motion of two mouth energy direct-driving motors, it has larger current driving ability, and every passage capable of being is by the persistent current of 750-800mA, and the peak current ability can reach 1.5-2.0A; It has lower output saturation pressure drop simultaneously; Built-in clamping diode can discharge the reverse impact electric current of inductive load, makes it safe and reliable in the use that drives relay, DC machine, stepping motor or switching power tube.Chip L9110 is widely used on the circuit such as toy car motor-driven, stepping motor driving and switching power tube.
The principle of work of control circuit is: when people's hand or object proximity dog-house (induction window) approximately during 15cm-30cm, the infra-ray sensing detector can detect and produce a high level signal (3V high level) automatically, carry out signal by first amplifying circuit and amplify (5V high level), again signal is passed to negative circuit and carry out negate, then the conversion of realization high-low level is sent to governor circuit external interrupt IO mouth P3^2; When nobody is close, infra-ray sensing detector output low level, negative circuit output high level, governor circuit can not respond.Response was interrupted after governor circuit was received signal (low level), produce PWM forward rotation signal, aerotron by the second amplifying circuit carries out the signal amplification, then pass through photoelectric isolating circuit, finally pass the signal to the motorized motions circuit of DC motor, the work of driving DC motor is opened automatically by the gear driven lid that connects dustbin cover and electrical motor.Drop into complete rear (delaying time approximately 3 seconds) in rubbish, governor circuit can produce again the PWM reverse signal and drive DC motor work, with cover closing.So just can realize the Based Intelligent Control of sewage disposer.
Above-described embodiment only is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other are any not to deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
