Description
One, technical field:
The utility model relates to a kind of instrument, particularly discloses a kind of water meter, gas meter, flow meter, the wireless signalling generator of ammeter automatic data logging, belongs to the electronic instrument class.
Two, background technology:
Enter the late nineteen eighties in last century, people bring into use keyboard-type write by hand machine, but owing to machine, table do not have interface, all disadvantages of manual metering still exist.In order to solve the problem of difficult charge, various IC-card formula tables have been produced.Now with regard to IC-card formula water meter, mainly there is following problem: one,, can't calculate of that month water yield loss because IC-card belongs to the forward purchasing water yield.For computed losses, still need manual metering.Two, table meter running status can't be known, the inspection regularly of also need sending someone, and also artificial inspection also can't be concluded table meter quality.It should be noted that especially: card water meter, the cassette gas meter owing to adopt powered battery, when battery electric quantity is sufficient, can also drive valve event.But when battery electric quantity is low, because the effect of hydraulic pressure, air pressure does not just again drive valve; Secondly, because quality problem, the long-time running incrustation scale adheres to, and the power that drives valve just must strengthen, and Here it is moves ineffective reason place card water meter day long afterwards.In a word, it exists the client easily to steal water, and water undertaking's investment increases and can not increase efficiency by downsizing payrolls, and promptly can not change original relations of production and liberate the productive forces.Therefore, nation-building portion clearly indication in notice: because the poor availability of homemade IC-card formula table should not be selected for use in urban and rural residents' " Every household has an ammeter " improvement project.After entering the nineties, centralized automatic meter-reading adopts the cable data transmission substantially.If come Data transmission with wired, technology is simple, ripe, is easy to realize; Construction installation work amount is big, and netting twine is subject to artificial destruction, and after circuit damaged, the trouble spot is easy-to-search not.Wireless kilowatt meter reading-out system also began should use gradually in kilowatt meter reading-out system in recent years, through operation in a few years, the problem that present wireless kilowatt meter reading-out system mainly exists has following some problem: one, wireless communication hardware adopts mimic channel, change with ambient temperature and humidity, frequency shift (FS) is serious, and communication reliability is bad; Two, traffic rate is low, and efficient is low; Three, communication distance is nearer, and the kilowatt meter reading-out system circumstance complication is difficult to use; Four, the whole immature wireless communication technology that causes of wireless communication technology is slower in the whole popularization of the industry of checking meter; Five, system power dissipation is bigger, and service time is short; Six, the whole cost of radio meter register is higher, is difficult to batch machining, is difficult to promote.
In a word, the drawback with upper type is: one, fettered the liberation of yield-power greatly; Two, work quality is poor; Three, cycle of checking meter is long; Four, service quality is low; Five, table meter running status can't be monitored; Six, the loss statistical fluctuations is big; Seven, day, month, annual consumption is not statistical uncertainty really; Eight, the phenomenon that disturbs residents is serious; Nine, operating cost height.Electric weight, the water yield, tolerance loss seriously certainly will cause the water, electricity, gas rise in price, form vicious cycle, excite the imbalance between supply and demand of society.
Three, summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of wireless communication hardware to adopt digital circuit, little with the skew of ambient temperature and humidity change frequency, communication reliability is good, the traffic rate height, the efficient height, communication distance is far away, and system power dissipation is little, and service time is long, satisfy country's intelligence table and use the requirement in＞6 years, disclose low a kind of water meter, gas meter, flow meter, the wireless signalling generator of ammeter automatic data logging of the whole cost of a kind of radio meter register.
The utility model is achieved in that a kind of water meter, gas meter, flow meter, the wireless signalling generator of ammeter automatic data logging, it is characterized in that: it is interconnected to a system by single-chip microcomputer, wireless telecommunications chip, wireless communication signals processing, power supply, single-chip microcomputer is used for the pulse signal of directly gathering water meter, gas meter, flow meter remote installed meter tool is counted automatically, single-chip microcomputer passes through the interrupt mode pulse signal of monitoring form tool constantly simultaneously, prevent taking out stitches, preventing trimming, and the remote installed meter tool is subjected to the signal of rogue attacks; Whether the single-chip microcomputer also electric weight of time monitoring power supply can keep system works, if electric quantity of power supply is lower than the minimum amount of power of default, single-chip microcomputer will produce warning and by wireless telecommunications chip and wireless communication signals treatment circuit alerting signal be launched; Wireless telecommunications chip and wireless communication signals treatment circuit are mainly used in the various data of system are carried out wireless transmission.Described water meter, gas meter, flow meter, the wireless signalling generator of ammeter automatic data logging are connected with concentrator, write by hand device, administrative center in the wireless long-distance meter-reading system.The application of wireless long-distance meter-reading system separate case, this case is not described in detail.Wireless signalling generator is transmitted into the distance of concentrator greater than 600 meters.Power supply in the system adopts lithium battery work, and system's average power is used 3.6V, 3.6A/h disposable lithium cell less than 20 μ A, and the working time was greater than 8 years.
The utility model helps to reduce system power dissipation, improves emissive power, strengthens communication distance.
The utility model mainly has following beneficial effect:
1, the utility model adopts advanced wireless communication technology, under same power consumption and emissive power, can strengthen communication distance, improves the reliability of system communication.
2, cost is low, is convenient to install, and is convenient to safeguard that the work of checking meter is simple, has reduced labour intensity, has improved production efficiency.
3, system power dissipation is low, adopts disposable lithium cell power supply fully, system's continous-stable work for up to 6～8 years, substantially exceed the requirement of country to intelligence table tool mission life.
4, the metering, malfunction monitoring, warning, power management, radio communication of table tool be in one, thereby reduced the whole cost of system, is easy to promote.
5, owing to adopt the wireless communication interface design, need not line, be easy to realize the senior sealing of whole signalling generator, for dustproof, it is fairly good that moistureproof design can be done, particularly can long-term work in the kitchen, the place of toilet, industrial environment, the inclement conditions such as other environment that duck in drink.
6, eliminate the error that manual operation causes, improve the intelligent degree of total system, reduce the waste of resource, help strengthening modern management.
