Description

A kind of current testing circuit of ecological room

Technical field

The utility model relates to circuit field, particularly a kind of current testing circuit of ecological room.

Background technology

Ecological room design of Controller theory is that imitation meets human body more a good life, rest environment arise at the historic moment technology-imitation natural ecological environments such as application message electronics, the effect that can play beauty treatment, skin care, takes care of health.Be integrated into a control system with these more existing practical techniques and realize that total system is divided three modules: air-conditioning control module, central controll block, human-computer interaction module, realize mutually by communication modes between three control modules between the information transmission.

But the current testing circuit that always lacks so far, a kind of not only simple but also effective ecological room.

Summary of the invention

The utility model provides a kind of current testing circuit of ecological room of simple and effective ecological room in order to overcome the deficiency of above technology.

The utility model is realized by following measure:

A kind of current testing circuit of ecological room is formed by connecting by 1,7 water level test electrodes of a chip IC (d1-d7), 14 resistance (R1-R14), 6 light emitting diodes (LED 1-LED6), 2 diodes (C1, C2), 2 power supplys (E1, E2), a hummer BUZ:

7 water level test electrodes (d1-d7) link to each other with 1～No. 7 pin of main control chip IC input end by resistance R 1～R7 respectively, and No. 8 pin of main control chip IC are earth terminal; No. 9 pin of the output terminal of main control chip IC1 directly link to each other with the feeder ear of 9V, 10～No. 15 pin of the output terminal of main control chip IC link to each other with the feeder ear of described 9V with the series circuit of LED 1～LED6 and resistance R 9～R14 series connection back respectively, link to each other with the feeder ear of described 9V after No. 16 pin of main control chip IC and hummer BUZ and resistance R 8 series connections;

There is a public electrode to link to each other with the feeder ear of described 9V, be parallel with the series circuit of capacitor C 1 and power supply E1 between No. 9 pin of the output terminal of public electrode and main control chip IC1, the positive pole of power supply E1 links to each other with No. 9 ports, minus earth, be parallel with the series circuit of capacitor C 2 and power supply E2 between No. 9 pin of the output terminal of main control chip IC1 and the feeder ear of above-mentioned 9V, the positive pole of power supply E1 links to each other minus earth with the feeder ear of 9V.

The beneficial effects of the utility model are: realize detection to water level by this circuit, as prompting, improved the intelligent degree in ecological room with the sound of hummer.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below preferred embodiment of the present utility model and conjunction with figs. describes in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Fig. 1 is the driving circuit schematic diagram of current testing circuit of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is made specific description.

The driving circuit schematic diagram of the current testing circuit of present embodiment is as shown in drawings:

A kind of current testing circuit of ecological room is formed by connecting by 1,14 resistance of a chip IC (R1-R14), 6 light emitting diodes (LED 1-LED6), 2 diodes (C1, C2), 2 power supplys (E1, E2), a hummer BUZ:

7 water level test electrodes link to each other with 1～No. 7 pin of main control chip IC input end by resistance R 1～R7 respectively, and No. 8 pin of main control chip IC are earth terminal; No. 9 pin of the output terminal of main control chip IC1 directly link to each other with the feeder ear of 9V, 10～No. 15 pin of the output terminal of main control chip IC link to each other with the feeder ear of described 9V with the series circuit of LED 1～LED6 and resistance R 9～R14 series connection back respectively, link to each other with the feeder ear of described 9V after No. 16 pin of main control chip IC and hummer BUZ and resistance R 8 series connections;

The concrete mode of operation of current testing circuit of the present utility model is as follows:

7 electrodes (d1-d7) are surveyed the waterline of 7 degree of depth respectively, and electrode d7 records top waterline for overflowing waterline.

LED 1～LED6 is as the usefulness of output terminal duty demonstration.

When water level rises, when its electrode catheter contacts with water successively, then 7～of the input end of main control chip IC No. 1 pin become high level successively, then 10～No. 16 pin of output terminal of main control chip IC1 also become low level successively, LED 1～LED6 lights in succession as a result, in case when overflowing water level and contacting with water (peak level), the external hummer BUZ of No. 16 pin of main control chip IC sends sound, the prompting water level has arrived set point.

The foregoing description just is to allow the one of ordinary skilled in the art can understand content of the present utility model and enforcement according to this for technical conceive of the present utility model and characteristics being described, its objective is, can not limit protection domain of the present utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the present utility model.
