Abstract
The invention relates to the technical field of water meter, specifically relates to a water meter valve detection circuit, comprising: an in-position switch detection circuit for detecting the opening state of a water meter valve and transmitting the detection signal to a microcontroller, and a microcontroller for receiving the detection signal of the in-position switch detection circuit and controlling opening of the water meter valve. The circuit is simple in the structure and combines the in-position detection, time detection and current detection together by means of an OR relationship. Once reaching one of the above conditions while use, there will be a fault alarm, and thus the preciseness is greatly improved. Furthermore, the deficiency of alarming is effectively improved, the expenses of cost are effectively optimized, as a result, the replacement rate of batteries is greatly reduced, and cost is further reduced. The circuit can discover problems of a valve in time so as to reduce the loss of a user to be the least. Additionally, in the later period, the alarming information can be synchronously reflected to the software in an upper computer by medium, which is beneficial to the collection and editing for a manager so as to plan the coping strategies in the later period.
Description
Technical field
The present invention relates to the water meter technical field, relate in particular to a kind of water meter valve testing circuit.
Background technique
Since reform and opening-up, China's urban population sharply increases.Along with the rapid expansion of Construction Scale of Residential Building, the installation quantity of water meter also increases considerably.The using scope of IC card water meter is also along with expansion.Along with the expansion of IC card water meter using scope, also show gradually some problem places, the valve of IC card water meter reliably switch puts in place very crucially, and this has determined the normal use condition of IC card water meter.The IC card water meter of domestic a lot of manufacturers can't detect valve switch and whether put in place, and the product of indivedual producers adopts is the mechanical type detection technique that puts in place.If adopt the machinery detection mode that puts in place, when valve forwards to, the collision machine contact, thus realize shutting down.If because the valve rust extremely causes the battery over-discharge can, thereby make brownout, valve can not run well again.So, the follow-up expenses such as maintenance valve, replacing battery all can increase thereupon, have caused waste to a certain degree at cost.Obviously, this mode complex structure, poor reliability can not waterproof, antirust, easily misoperation.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, and a kind of water meter valve testing circuit is provided, can accurately judge failsafe valve, improve the reliability of water meter integral body.
The present invention for achieving the above object, by the following technical solutions: a kind of water meter valve testing circuit is characterized in that: comprising:
The location switch testing circuit for detection of the opening state of water meter valve, and is transferred to microcontroller with testing signal;
Microcontroller is used for receiving the testing signal of described location switch testing circuit, and controls the unlatching of water meter valve.
Described location switch testing circuit is comprised of current-limiting resistance, divider resistance, optocoupler, and valve is connected with the input end of optocoupler with the current-limiting resistance series connection is rear, and the output terminal of optocoupler is connected with microcontroller.
Described divider resistance is three, and is connected in parallel.
Also comprise time detection circuit, for detection of the shut-in time of valve, and the time value that gathers is transferred to microcontroller.
Also comprise current detection circuit, the current value during for detection of valve closing, and the current value that gathers is transferred to microcontroller.
The invention has the beneficial effects as follows: the present invention is simple in structure, with the detection that puts in place, time detecting and current detecting by or relation combine.As long as in use reach a kind of malfunction alarm that just has in the above-mentioned condition, preciseness improves greatly.Effectively improved the disappearance on reporting to the police, effectively optimized the expenditure on the cost, reduced meaningless power consumption loss, made the battery altering rate greatly reduce Cost reduction.Can find in time that problems with valves keeps in repair, drop to user's loss minimum.Later stage can be reflected to warning message on the upper computer software synchronously by medium, is conducive to the manager and gathers editor, has planned the later stage countermeasure.
Description of drawings
Fig. 1 is principle of the invention block diagram;
Fig. 2 is the schematic diagram of location switch testing circuit among the present invention.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of water meter valve testing circuit comprises: the location switch testing circuit for detection of the opening state of water meter valve, and is transferred to microcontroller with testing signal; Microcontroller is used for receiving the testing signal of described location switch testing circuit, and controls the unlatching of water meter valve.Described location switch testing circuit is comprised of current-limiting resistance R1, divider resistance R2, R3, R4, optocoupler T1, and valve is connected with the input end of optocoupler with the current-limiting resistance series connection is rear, and the output terminal of optocoupler is connected with microcontroller.Described divider resistance is three, and is connected in parallel.When valve rotate in place; the driving current of valve increases suddenly; so that the light emitting diode conducting of optocoupler inside, make it to send the light of certain wavelength, received by photodetector and produce photoelectric current; microcontroller detect optocoupler because of the conducting of valve stall after; namely can send the instruction of shutdown, by electronic switch cutting-off valve control power supply, valve current sinking this moment is zero; putting in place of valve detects the unnecessary waste of energy that has reduced battery, the working life of having improved battery.
Also comprise time detection circuit, for detection of the shut-in time of valve, and the time value that gathers is transferred to microcontroller.If during greater than 15 seconds, then carrying out failsafe valve when stopping valve event, closing valve time reports to the police.
Also comprise current detection circuit, the current value during for detection of valve closing, and the current value that gathers is transferred to microcontroller.Electric current when closing the valve closing that valve detects then carries out failsafe valve and reports to the police during greater than 450mA when stopping valve event.
The present invention is simple in structure, with the detection that puts in place, time detecting and current detecting by or relation combine.As long as in use reach a kind of malfunction alarm that just has in the above-mentioned condition, preciseness improves greatly.Effectively improved the disappearance on reporting to the police, effectively optimized the expenditure on the cost, reduced meaningless power consumption loss, made the battery altering rate greatly reduce Cost reduction.Can find in time that problems with valves keeps in repair, drop to user's loss minimum.Later stage can be reflected to warning message on the upper computer software synchronously by medium, is conducive to the manager and gathers editor, has planned the later stage countermeasure.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
