Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.

As shown in Figure 1, the utility model comprises a voice single-chip microcomputer mainboard 1, LED light 2, a slot type optoelectronic switch 3 and a Hall flow sensor 4.Single-chip microcomputer mainboard 1 is sealed in the can 5, and LED light 2 is arranged on the can 5, and connects single-chip microcomputer mainboard 1 through lead.Can 5 is placed in by the original prefabricated card-inserting device of boiled water room.Slot type optoelectronic switch 3 is installed in original campus card 6 Insert Card Heres, makes plug-in card or when pulling out card, slot type optoelectronic switch 3 can produce corresponding induced signal, and induced signal passes to single-chip microcomputer mainboard 1 through signal transmssion line.Hall flow sensor 4 is connected on 7 water outlets place of boiled water room water swivel, and induced signal also passes to single-chip microcomputer mainboard 1 through signal transmssion line.

Consider that the utility model is applied to the water swivel position; Therefore the small-sized single-chip microcomputer mainboard of suitable employing, owing to need audible alarm, the SPCE061A single-chip microcomputer mainboard that has therefore adopted Ling Yang company to produce is simplified plate in addition; It is integrated microphone, and the I/O interface of 16 customized justice is provided.As shown in Figure 2, as signal output, port IOB0～IOB15 is set to the high level output with metadata cache with the IOB of SPCE061A single-chip microcomputer mainboard; IOA is used as the signal input, and port IOA0～IOA15 is set to drop-down low level input; Wherein loudspeaker output 8 adopts mainboard from ported; The 15th port of IOB is connected LED light 2 with the VCC port; The IOA0 of IOA is connected slot type optoelectronic switch 3 with VCC; The IOA8 of IOA is connected Hall flow sensor 4 with VCC.Because the optoelectronic switch 3 of the utility model preferably has the sensitivity adjusting function; And because the WV of single-chip microcomputer mainboard 1 restriction; The output voltage of optoelectronic switch 3 preferably can be in 5V, so the ITR9608-F slot type optoelectronic switch of selling on the optoelectronic switch 3 employing markets of the utility model (being not limited thereto) with photodiode.When having foreign matter to block light path in the groove, slot type optoelectronic switch 3 can produce corresponding induced signal, and passes to single-chip microcomputer mainboard 1, thereby whether detecting has inserted campus card.As shown in Figure 3, Hall flow sensor 4 can adopt the YF-21 Hall flow sensor of selling on the market, and this sensor is applied on the pot-type boiler mostly, in this having or not in order to the detecting current.The pulse signal of Hall flow sensor 3 output high-low level forms, the umber of pulse of 1 pair of this signal of single-chip microcomputer mainboard is counted, if umber of pulse is less than the value of setting (such as 5, but being not limited thereto) in count cycle, then thinking does not have current to pass through; Otherwise thinking has current to pass through.

The principle of work of the utility model is: when inserting card in the original card-inserted device of campus boiled water room; When connecting original water flowing solenoid valve; Slot type optoelectronic switch 3 is sensed the insertion of card; The output high level signal is sent to the corresponding port of single-chip microcomputer mainboard 1, and single-chip microcomputer mainboard 1 puts 1 with relevant variable card, and it is long bright that output order makes LED light 2 simultaneously.Behind the tap of fetching boiling water; Hall flow sensor 4 is sensed the generation of current, and output pulse signal is sent to the corresponding port of single-chip microcomputer mainboard 1, and single-chip microcomputer mainboard 1 converts this pulse signal into high level; Water puts 1 with relevant variable, and output order makes LED light 2 flickers simultaneously; When having beaten water, having closed water swivel and when not pulling out card; Hall flow sensor 4 is sensed the disappearance of current, and output constant level is sent to the corresponding port of single-chip microcomputer mainboard 1, and single-chip microcomputer mainboard 1 is a low level with this constant level conversion; Water puts 0 with relevant variable; It is long bright that output order makes LED light 2 simultaneously, and produce voice signal, and playing back music is reported to the police in the loudspeaker that carries; After taking out card, the water flowing closed electromagnetic valve, slot type optoelectronic switch 3 is sensed the disappearance of card; The output low level signal is sent to the corresponding port of single-chip microcomputer mainboard 1; Single-chip microcomputer mainboard 1 puts 0 with relevant variable card, and output order goes out LED light 2, and music alarm stops simultaneously.

As shown in Figure 4, when the utility model uses, may further comprise the steps:

1) inserts campus card;

2) detect plug-in card:

If behind the plug-in card, original water flowing solenoid valve access failure, the LED lamp does not work, and then pulls out card, returns step 1);

If solenoid valve is connected, the LED lamp is long bright, gets into step 3);

Whether 3) detect water swivel opens:

If water swivel is opened, whether the flicker of LED lamp detects water swivel again and opens;

If water swivel is closed, get into step 4);

4) detect whether pulled out card:

If pulled out card, closed electromagnetic valve, the LED lamp is closed, and music alarm stops when music alarm, gets into step 6);

If do not pull out card, solenoid valve is still connected, and then through after the circulation time-delay, gets into step 5);

Whether 5) detect water swivel opens:

If water swivel is opened, step 3) is returned in the flicker of LED lamp;

If water swivel is closed, the LED lamp is long bright, and card is pulled out in music alarm prompting simultaneously, returns step 4);

6) finish.

Above-mentioned steps 4) in; For avoiding before the release of normal switch water swivel; The single-chip microcomputer mainboard just detects having or not of current and produces miscue; The single-chip microcomputer mainboard can be provided with circulation time-delay control module, and execution is delayed in the operation that gets into step 5), and this circulation time-delay control module can be used a chronotron or utilize programmed statements to realize.

Above-mentioned each embodiment only is used to explain the utility model; Wherein the structure of each parts and connected mode etc. all can change to some extent; Every equivalents of on the basis of the utility model technical scheme, carrying out and improvement all should not got rid of outside the protection domain of the utility model.
