(2) background technology
At present in the existing intellectual remote transmitting water meter, the overwhelming majority adopts is that tongue tube or Hall element are as data sampling sensor.Its ultimate principle is the corresponding place of pointer that tongue tube is installed in the base table counter.On pointer, be embedded with magnetic material.The moving circle of this pointer revolution, tongue tube switching once, Single Chip Microcomputer (SCM) system is come the flow of metering water meter by the switching that detects tongue tube.The defective of this mode maximum is that the single-chip microcomputer acquired signal can produce misoperation (because of tongue tube frequent switching under water hammering is rotated inharmonious with pointer) when water hammer appears in water system.Influence measuring accuracy.Simultaneously as circuit partly waterproof go wrong, then when water or water vapour enter circuit partly after, can cause the partial short-circuit of circuit part, then its consequence is to cause the teletransmission part with complete failure.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can guarantee the partly passive direct-reading remote transmitting water meter of reliability service of circuit component failure that the partly reliable effectively unlikely appearance of waterproof of water meter measurement accuracy and circuit causes because of waterproof and teletransmission circuit.
The purpose of this utility model is achieved in that a kind of passive direct-reading remote transmitting water meter, comprise the character wheel box, character wheel, power wheel, circuit partly, sign board, water gage glass, trim ring and teletransmission lead, it is characterized in that: be provided with a step interlayer in the middle of the described character wheel box, this step interlayer is divided into an airtight cavity with character wheel box lower part, described character wheel and power wheel are installed in this airtight cavity, filling liquid in this airtight cavity, described circuit partly includes single-chip microcomputer, constitute Single Chip Microcomputer (SCM) system, described circuit partly is arranged in the small diameter bore of the character wheel box above the described step interlayer, separate fully with the liquid in the described airtight cavity, described water gage glass and sign board are arranged in the large diameter hole of the character wheel box above the described step interlayer, water gage glass places the sign board top, trim ring is pressed on character wheel box top and water gage glass apical margin, slit between described circuit part and the character wheel box, in the slit between slit between character wheel box and the sign board and character wheel box and the water gage glass marine glue is set, teletransmission partly links to each other with circuit with lead one end, the other end is by drawing in the described slit outside the described trim ring, set the O RunddichtringO between described sign board outer rim and the character wheel box inwall, described character wheel midfeather is equipped with many group photoelectric tubes, corresponding to described photoelectric tube, a plurality of ring-like windows have been opened in the corresponding position on the character wheel, constitute sampling section with photoelectric tube.
Its principle mainly contains two aspects:
The one, liquid, character wheel and power wheel are by the character wheel box and cover 8 and be sealed in the cavity of a sealing, guaranteed that photoelectric sensor is luminous and remained unchanged by the medium between light-path, guaranteed the consistance of infrared light transmission and the accuracy that single-chip microcomputer is differentiated the character wheel position.
The 2nd, circuit partly is sealed in the cavity of a sealing by character wheel box, sign board, O RunddichtringO, water gage glass, trim ring and marine glue, has guaranteed circuit effective waterproof and teletransmission circuit reliability service partly partly.
First characteristics of the present utility model are by being installed in three groups or four groups of photoelectric tubes in the middle of the character wheel, cooperating the windowing on the character wheel, differentiate the character wheel position with singlechip technology, thereby have reached the purpose of metering.Realize the correct metering of water meter.
Second characteristic of the present utility model are that partly electronic component and circuit separate itself and outside air, fluid-tight with liquid, tap water fully partly by designs such as marine glue and liquid fluid-tights in sampling.Reached the partly optimum efficiency of waterproof of circuit.Guarantee the operate as normal and the correct metering of remote transmitting water meter.
To sum up, the utility model has following advantage:
1, photoelectric sensor is luminous and remained unchanged by the medium between light-path, has guaranteed the accuracy that consistance that infrared light transmits and single-chip microcomputer are differentiated the character wheel position.
2, structure optimization, waterproof effect are very desirable.
