Description
Technical field
The utility model relates to the wireless transmitting system technical field, is specifically related to the Wireless water meter reading system based on Zigbee and GPRS.
Background technology
At present, whole world water resource constantly reduces, and the even external a lot of cities of China all face the situation that seriously lacks drinkable water, and city tap-water is supplied with effective management and seemed very important.China is carrying out reconstruction of the old city town recent years energetically in addition, builds intellectual communityintellectualized village to promote comfort level per capita, and these have all proposed challenge to existing conventional water meter and manual metering mode.For a long time, what China town dweller generally used is the cheap mechanical water meter of stable performance, yet along with society constantly develops, the continuous increase of modernization skyscraper and intelligent residential district, the shortcoming of some other meter reading methods that Traditional Man meter reading method and existing market exist comes out gradually.
One, traditional manual metering mode: the meter reading personnel registers one's residence and reads user's water data, then adds up charging, then charges in user family.There are a lot of drawbacks in this method:
1. checking meter, labor intensity is large, efficient is low;
2. leak to copy and copy unavoidably by mistake;
3. the cycle of charging from checking meter to is long;
4. managerial cost are high;
5. easily pretended to be by the offender, have potential safety hazard.
But China's most area is still take the Traditional Man meter reading method as main.
Two, IC-card formula prepayment mode: the meter reading personnel need not user place, and the user provides consumption by the bank transfer expense or to water resource management department purchase magnetic card, IC-card etc. by the purchase volume, completes fee collection.It has the water of limiting the quantity of, the water conveniently function of paying, and do not need again to lay spool, easy to install.But external a lot of developed country does not advocate this way of paying, and reason is that they not think and allow the resident because unpaid water rate and lose the right of basic water resource of use for the moment.
Three, teletransmission meter reading method: it is to utilize concentrator that the data that intellectual water meter collects are preserved, processed, and is connected with computing machine by network-bus, can as requested and carry out message exchange between computing machine.Mainly include line and wireless two kinds of transmission modes, this meter reading method is convenient and reliable, and wherein wired input cost of checking meter is large, needs to lay a large amount of communication lines and builds large-scale data center and carry out data maintenance.Support the water meter of this meter reading method mainly to comprise GPRS radio meter register, power line carrier water meter and shooting direct reading remote watermeters etc.
(1) GPRS radio meter register: water meter has data metering and processing capacity, and data realize receiving and sending by wireless mode (GPRS/CDMA).This type of water meter need not laying-out, safeguards with easy for installation, and great majority use the amateurish wireless frequency of international standard and homemade private communication protocol.But because single table installs wireless transmitter additional, the corresponding raising of cost, and often need to change battery, more because take the wireless frequency of charge, also need pay certain rent and overhead cost; There is in addition the safety problem of data communication, so use seldom on domestic meter market at present.
(2) power line carrier water meter: abroad under the impact of power line carrier water meter widespread use, China also constantly low pressure carrier wave technical strive obtaining further develop, a lot of mechanisms put forth effort to work out and utilize low-voltage power line as the intelligent telemetering water meter of communications carrier.But crucial power line carrier special chip is mostly produced by external company, adds that the interference ratio of China's electrical network is larger, so can this water meter reliably use also still discussing, make this remote transmitting water meter widespread use also need further research.
(3) shooting direct reading remote watermeters: pinhole cameras is installed on intellectual water meter, takes in real time the image of water meter Water usage, because the electric current of water meter is very little, so wiring is convenient, the time that use is long.Can the picture of water data be transferred to the pulpit in a distant place by hand-held set or wired mode.But the cost of this shooting direct reading remote watermeters is larger, restricted by development condition.
In sum, all there is following problem in above-mentioned several water meter scheme:
(1) use cost is higher
The GPRS/CDMA data transmission needs to pay, and for family's water meter reading, the operating cost of system is very high;
(2) network is limited from managerial ability
Adopt wireless data transmission module, increase with nodes except the data polling time and linear increase, the wireless network of setting up very limited from management function increases or reduces node, all needs manually to go to revise corresponding database configuration; Node breaks down, and also usually needs manually to go diagnosis etc.;
(3) powerup issue of meter reading terminal is difficult to solve well, because meter reading terminal is difficult to accomplish extremely low power dissipation, so powerup issue is a bottleneck all the time.
Summary of the invention
The technical problems to be solved in the utility model is to provide the Wireless water meter reading system based on Zigbee and GPRS, the utility model efficiently solves the meter reading method of at present existing water meter, there is the problem that use cost is high, network management capabilities is poor and power consumption is high, the utility model is simple in structure, reasonable in design, is convenient to Industry Promotion and uses.
The utility model is achieved through the following technical solutions:
Wireless water meter reading system based on Zigbee and GPRS, comprise intellectual water meter, it is characterized in that: described system comprises data acquisition end, data set middle-end and data end for process, Wireless Data Transmission between data acquisition end, data set middle-end, data end for process; Described data acquisition end comprises a plurality of data acquisition nodes, described data acquisition node integrated monolithic machine, wireless transport module, data-interface A and working power, and intellectual water meter is connected with single-chip microcomputer by data-interface; Described data set middle-end integrated monolithic machine, wireless transport module, GPRS chip and working power; Described data end for process comprises host computer and host computer data acquisition node, host computer data acquisition node integrated monolithic machine, GPRS chip, data-interface B and working power, and the host computer data acquisition node is connected with host computer by data-interface B.
