The mark of each parts is following in the accompanying drawing: 1, Storage water tank, 2, metallic object, 3, plastic body, 4, caulking groove, 5, water proof wire, 6, single chip machine controlling circuit, 7, acoustical generator, 8, alarm lamp.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Fig. 1 is an embodiment of the invention rainwater warning device structural representation; This rainwater warning device comprises Storage water tank 1, single chip machine controlling circuit 6, acoustical generator 7 and alarm lamp 8; Described Storage water tank 1 is made up of metallic object 2 and plastic body 3; Described single chip machine controlling circuit 6 is made up of AT89S51 single-chip microcomputer, resistance, electric capacity and crystal oscillator; Described acoustical generator 7 adopts hummer, and described alarm lamp 8 adopts red light-emitting diode, and described Storage water tank 1 couples together through water proof wire 5 with described single chip machine controlling circuit 6.
Fig. 2 is an embodiment of the invention rainwater warning device circuit theory diagrams; This rainwater warning device has adopted the AT89S51 single-chip microcomputer as kernel control module, and the P1.0 pin of this single-chip microcomputer is connected with the negative electrode of light emitting diode L1, and the P3.0 pin is connected with an end of Storage water tank K switch, and the P0.0 pin is connected with the base stage of triode Q1.The power supply VCC that selects for use is+the 5V rechargeable battery that it is convenient and swift to supply power, and is beneficial to the rainwater warning device and moves use.Power supply VCC respectively with the anode of light emitting diode L1, the emitter of triode Q1, the P3.0 pin of single-chip microcomputer, VCC pin, EA pin connect.Under the power supply of power supply VCC, the anode of light emitting diode L1 is a high level, and the emission of triode Q1 is high level very.If make light emitting diode L1 send ruddiness, then the negative electrode of light emitting diode L1 is necessary for low level, and promptly the P1.0 pin of single-chip microcomputer is a low level; If make triode Q1 conducting and drive the hummer sounding, then the base stage of triode Q1 is necessary for low level, and promptly the P0.0 pin of single-chip microcomputer is a low level; If making the P3.0 of single-chip microcomputer is high level state, then in the Storage water tank rainwater can not be arranged, be off-state; If making the P3.0 of single-chip microcomputer is low level state, then in the Storage water tank rainwater to be arranged, be on-state.According to above-mentioned control requirement, can design SCM program and be loaded in the singlechip chip.As long as power supply power supply, single-chip microcomputer just can drive alarm lamp 8 luminous and acoustical generator 7 sounding according to the rainwater situation in the Storage water tank.That is to say that when falling into rainwater in the Storage water tank it is low level and then to P0.0 and P1.0 output low level that single-chip microcomputer detects P3.0, thus drive alarm lamp 8 luminous with acoustical generator 7 sounding; When not falling into rainwater in the Storage water tank, it is high level and then to P0.0 and P1.0 output high level that single-chip microcomputer detects P3.0, thus cut off alarm lamp luminous with the acoustical generator sounding.
The present invention has disclosed a kind of rainwater warning device, and this rainwater warning device is simple in structure, removable arrangement; Adopt the intelligent control of 51 chip microcontroller of Low-voltage Low-power, simplified circuit structure, environmental suitability is strong, and reliability is high; The Storage water tank design is unique, can in time clear up rainwater, possesses the switching function that detects rainwater; Adopt rechargeable battery poweredly, it is convenient and swift to supply power.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
