Description
Technical field
The utility model is related to originally drainage facility field, more particularly to a kind of valve control water meter intelligent concentrator.
Background technology
Under the existing national conditions of China, the problem of there is meter reading hardly possible, difficult charge in part region, " first paying dues, water is used afterwards "
Pattern also has sizable use ratio, and conventional " pre-payment " product is mainly with IC-card（Radio frequency and contact）Intellectual water meter
Based on, IC-card intellectual water meter solves the problem of meter reading and charge, realizes that owner oneself actively arrives and sells water spot recharging and paying, simultaneously
Manual metering is saved, it is time saving and energy saving, but IC-card intellectual water meter is all remote from table body structure, production procedure or manufacturing cost
Far above common valve control water meter, and IC-card intellectual water meter has certain limitation to use environment, and traditional IC-card intellectual water meter is needed
Install indoors, and the open environment in space, it is easy to check data of water meter, brush/plug-in card operation and replacing battery etc..
The content of the invention
The utility model in order to make up the defect of prior art there is provided one kind be applicable various environment, without civil power, need not
The valve control water meter intelligent concentrator of networking.
The utility model is achieved by the following technical solution：
A kind of valve control water meter intelligent concentrator, it is characterized in that：Including master chip, the input of the master chip is connected respectively
Radio-frequency module, power supply, R232 Data entries interface and MBUS gathered data buses, the output end of the master chip are connected respectively
R232 data outlets interface, MBUS host datas output bus, liquid crystal display and LED light.
The master chip uses MSP430FR series monolithics.
The master chip uses FR6972, FR69721 or FR5739 single-chip microcomputer.
The power supply is the sub- battery of lithium.
The beneficial effects of the utility model are：
The utility model rich interface, possesses RFID technique, with MBUS longitudinal directions and RS232 serial interfaces, realizes data
Importing and export, it is and flexible for installation, conveniently, do not limited when being installed on table tool by installation site.It compensate for existing
The deficiency of pre-payment water meter, while reducing cost, is easy to review historical data.
Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is attachment structure schematic diagram of the present utility model.
In figure, 1 master chip, 2 power supplys, 3 radio-frequency modules, 4 R232 Data entries interfaces, 5R232 data outlet interfaces, 6
MBUS gathered data buses, 7 MBUS host data output bus, 8 liquid crystal displays, 9 LED lights, 10 host computer PCs, 11
Subordinate's water meter.
Embodiment
Accompanying drawing is specific embodiment of the utility model.As shown in figure 1, this kind of valve control water meter intelligent concentrator, including master
Chip 1, the input of master chip 1 connects radio-frequency module 3, power supply 2, the and of R232 Data entries interface 4 respectively, master chip 1 it is defeated
Go out end connection R232 data outlets interface 5, MBUS host datas output bus 7, liquid crystal display 8 and LED light 9 respectively；
Master chip 1 can use MSP430FR series monolithics, such as FR6972, FR69721 or FR5739 single-chip microcomputer.Power supply 2 can
To be the sub- battery of civil power or lithium；
It can be connected more than 100 between MBUS gathered datas bus 6 and MBUS host datas output bus 7 when used
Subordinate's water meter 11, realizes and carries out prepaid balance to the water meter in bus, master chip 1 records the instant number of each subordinate's water meter 11
According to and historical data, and be stored in the nonvolatile memory of master chip 1, it is right according to the data status of each subordinate's water meter 11
Water meter carries out the corresponding valve etc. that opens or closes and operated；
Host computer PC 10 is connected by the data outlet interfaces of R 232, can import data in host computer PC 10, pass through spy
Fixed key and agreement complete data interaction, the download of such as archives, the setting of parameter and the backup of data, are easy to manager to manage
Reason；
MBUS gathered datas bus 6 and the design of MBUS host datas output bus 7 follow standard CJ-T_188 agreements, including
Software data message format, transmission rate and type, the grade and voltage modulation index of transmission level；
All data storages are in master chip 1MCU, and the flash in MCU is divided into program code area and data storage area,
Refurbishing procedure code area when program updates upgrading, region of data storage does not change, and region of data storage was remembered comprising the history of 12 months
Record and instant data.
Charging mode：Three stepped water pricings, two ladder amounts, clearing Zhou Weiyi months, according to related water can at most be carried out
Table data remaining sum is performed and whether supplied water（Controlled valve）, this equipment is provided with balance reminding function, when remaining sum is less than setting value
Close valve to remind, user can swipe the card to remove and remind, and be continuing with remaining sum, until balance depletion, valve is closed, stop water supply.
Data encryption：Using two kinds of cipher modes, first, completed using 5577 card cryptographic blocks of itself to card data
Password is unique between encryption measures, and user, be effectively ensured it is technical crack, second, IC-card directly leads to present device
Interrogate message to transmit for ciphertext, further ensure the security of data, ciphertext cryptographic protocol is that this equipment is exclusive, key group leader,
Cipher mode is rigorous；
User can realize the supplementing with money of IC-card by radio-frequency module 3 using IC-card, check remaining sum etc., and IC-card is that 125KHZ is low
Frequency passive RFID, card uses model ATA55TT, internal common 363bit design space, and has more modulation mould
Formula configure, the application set IC-card configure content be：Transmission rate RF/32, coded system is Manchester codes, and maximum is read
Number is 6, using key WriteMode.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
