Abstract
The present invention relates to an instantaneous collection and transmission system of passive remote data for a non-electric quantity meter and a transmission method, which comprises the non-electric quantity meter, a data collector, a relay case and a data display box. A meter pointer is changed into a reflective pointer. The transmission method comprises the steps that the reflective pointer is reflected to an infrared receiving tube by the method that an infrared luminous tube acts on the reflective pointer; the receiving tube receives data of each scale of the reflective pointer; the scale data is converted into signal data and transmitted to the data display box; photoelectric information is converted into digital information by a logical judgement line in a box body; the information is transmitted on a computer or a monitoring system in the mode of a bus through a standard communication interface by a modem.
Description
Technical field
The present invention relates to a kind of new data acquisition, transmission and monitor mode of non-electric meters, especially a kind of remote passive data for non-electric meters instantaneous transmission mode.
Background technology
Because the work of checking meter of present most of non-electric meters is still the mode that adopts manual metering, particularly water meter, gas meter etc. have the instrument of a large amount of use colony, they really do not accomplish to read the ammeter directly as yet, make most of resident quite feel inconvenience, make Running-water Company and Gas Company feel that also workload is huge.And other non-electric meters that under environment harsh conditions such as security requirements such as oil field, chemical industry, oil refining, coal gas, chemical fertilizer, rock gas are high and poisonous, harmful, inflammable, explosive, use, the inconvenience of work and dangerous owing to check meter has increased work difficulty to the remote monitoring of total system for the departments concerned and enterprise.
In order to solve this difficult problem, the electronic type non-electric meters distance transmission system that has occurred all kinds of special purposes in the market, as electronic type remote transmission water meter centralized meter-reading system, electronic type remote transmission gas meter centralized meter-reading system etc., and bring into use in some areas.This class remote centralized meter-reading system does not enter the user door, less than scene, instrument position, can realize the remote transmission and the monitoring of instrumented data, has solved a difficult problem set forth above substantially.But existing all kinds of centralized meter-reading system, when providing convenience to everybody, all there is a very big hidden danger, Here it is they in the course of the work, must use power supply to carry out uninterrupted power supply, in case the outage phenomenon takes place, and system will not count or with stored loss of data, this just has influence on the normal work requirements and the interests of Running-water Company, Gas Company and all kinds of non-electric meters applying units.Present most of centralized meter-reading system has adopted battery as the accessory power supply of its system when cutting off the power supply, though manufacturer illustrates again and again, battery can be kept the serviceable life in 7～8 years, but who can't say also when battery can not have, in case battery can't be powered, then centralized meter-reading system will can not get instrumented data, originally store to such an extent that data also will be lost, this normal operation to system has caused very big inconvenience, has also influenced the interests of each side.
Existing all kinds of centralized meter-reading system is owing to need uninterrupted power supply, and the maintenance cost of system is very high, and the operation life and the tenure of use of system are restricted; And uninterrupted power supply is the circuit kit system, the problem of reliability aspect such as exist electric leakage, short circuit, open circuit, and the use of battery can not fundamentally address this problem.
Summary of the invention
The objective of the invention is at above-mentioned weak point, provide that a kind of reliability height, maintenance cost are low, long service life, need not brand-new the non-electric meters remote data instantaneous acquiring and transmission system and the transmission method thereof of powering at ordinary times, the present invention does not influence the normal function of measuring of non-electric meters in the past, can not only realize the remote meter-reading function of general centralized meter-reading system, and it need not the power supply power supply in routine duties.
Mentality of designing of the present invention is: the consideration of coming of metering instrument and sub data transmission.Because meter characteristic is the function that various instrument all have, and data are made a copy for and transmit and be only the most important thing that relevant department and enterprise are concerned about, and making a copy of of meter reading data is regularly to carry out substantially, only needed once in every month as water meter, gas meter, the non-electric meters that enterprise uses is also just monitored when needed, the operating position of instrument itself is not the emphasis that relevant department is concerned about, relevant department is concerned about is the instant data that can read instrument when needing, can the user of instrument and instrumentation be managed normally like this.Therefore, starting point of the present invention is: need not to provide uninterrupted power source to keep the normal operation of system, the line of total system and equipment are in no current, idle stationary state at ordinary times, that is to say: system is the process data of stores meter operation not; Only in the needs reading of data, monitor in, system just by the external power source connector (≤6V) or telephone wire or computer network line carry out instant reverse power supply, at this moment in the line of system and the equipment electric current arranged, enter duty, carry out reading of data, so that carry out the monitoring of system, that is to say: what system read is the point data in a certain moment in the instrument operational process, and the storage of data can realize by computer or supervisory system.
Instantaneous acquiring and transmission system of remote passive data for non-electric meters and transmission method thereof are to adopt following scheme to realize:
Instantaneous acquiring and transmission system of remote passive data for non-electric meters comprises non-electric meters, data acquisition unit, relaying box, data presentation case.
Data acquisition unit comprises wiring board retainer plate, printed-wiring board (PWB) and wiring board cover, and infraluminescence pipe, infrared receiving tube, connection plug are arranged on the printed-wiring board (PWB).Pointer on the non-electric meters is set at reflective pointer, at the non-electric meters upper unit wiring board retainer plate is arranged, device has printed-wiring board (PWB) on the wiring board retainer plate, and wiring board top is provided with the wiring board cover.Be provided with infraluminescence pipe, the infrared receiving tube of data acquisition unit at reflective pointer top correspondence position.
The relaying box has relaying box wiring board, on the relaying box wiring board there is device: leading-in socket, output socket, wiring board are provided with relaying box logic, and logic is made of electronic component and realizes.Link to each other by transmission line between data acquisition unit and the relaying box.
The data presentation case has the data presentation box body, device has LCD panel, address button, supply socket, leading-in socket, communication interface on the casing, device has modulator-demodular unit, data box printed-wiring board (PWB) in the casing, printed-wiring board (PWB) is provided with the logic determines circuit, and the logic determines circuit is made of electronic component and realizes.Link to each other by transmission line between relaying box and the data presentation case.
