The basic data of most preferred embodiment is:
Zero table number: 8 hexadecimal digits are water supply administrative authority unique passwords for this user's appointment;
Zero purchases the water yield: the water yield when at every turn purchasing water for the user, 4 10 system integers, 0～9999 cubic metre of scope;
Zero purchases the waterside number: 2 position effective digitals, and scope 0～99 time is finished automatically by management computer, and sign is used
Water is purchased in which time of family;
Zero warning lower bound (cubic meter): 2 position effective digitals, 0～99 cubic metre of scope is appointed by water supply department
Meaning is set;
Zero purchases water yield database at every turn: the storage user purchases the water yield at every turn, is to the maximum 99 times.This group data are for using
The water archives material at family;
The control of zero multilist: this controller can be hung 1～3 water meter simultaneously, and a solenoid valve is the master control valve.
When the forward purchasing water yield is zero, close the master control valve, and owe the water record, deduct when purchasing water once more.Operation instruction and principle of work:
The installation of zero water meter and initialization: water meter is installed by the technician of water supply administrative authority appointment.Install
Finish, use the initialization IC-card that microcomputer in the water meter and storer are carried out initialization, make it become sky
Table uses ready for the user is correct;
Zero user purchases water: the user according to self water consumption and economic strength to the administrative authority's forward purchasing water yield that supplies water.
In " IC-card water supply management system ", set up files on each of customers when purchasing water for the first time, determine relevant ginseng
Number is sold to user's IC-card;
Zero plug-in card water: the user holds IC-card, inserts in the table, enters the Card Reader operation.Water meter reads in the card automatically
Data, password check at first, conforming to as password then enters following steps, otherwise ignores.Its
Inferior, according to purchasing the waterside number, the water data of database is purchased in inquiry, and it is effective to purchase water, and then drive valve and send water,
And showing that successively this purchases the water yield and surplus water, every parameter shows 5 seconds, otherwise will not accept.So
The back is removed in the IC-card automatically and is purchased the water yield.Surplus water be last time surplus and this purchase water yield sum.Make
May cause cutting off the water supply with inserting illegal card in the process, should during showing, withdraw from IC-card, At All Other Times
Move back card, possible interference program operation.
Zero preserves files on each of customers: when Card Reader finishes, enter writing operation automatically, with historical number in user's water meter
According to all writing in the subscriber card.Before the user purchased water once more, water supply administrative authority examined, and builds
Upright files on each of customers.Can realize scientific management, carry out macro adjustments and controls, and prevent illegal for water
The behavior of data in the user's modification subscriber card;
Zero reports to the police: when user's surplus water was lower than the warning lower bound, barrier gate was cut off the water supply, and recovered automatically after 10 minutes
Supply water, and continue dynamically to show surplus water, remind the user to prepare to purchase water, after the forward purchasing water yield is zero
Then continue to show and owe the water yield, owing the water yield is increment;
Zero shows: water meter each minute, show this forward purchasing water yield, water consumption and surplus water successively,
Each parameter showed for 5 seconds, closed demonstration after demonstration finishes;
Zero work indication: when normal water, relay indicating light can be regularly bright dark, and instruction program is working properly.
Zero automatically resets: running into strong interference, when microcomputer lock machine and program flew to escape, system can be at one minute
In automatically reset, recover normally operation.
The utility model is no time-consuming in controller, and display shows " 0000 ", closes and cuts off the water supply, and when inserting effective IC-card (password is correct, and the forward purchasing water yield is arranged), controller reads in data in the card automatically, drives valve and send water.Per minute shows this forward purchasing water yield successively, water consumption and surplus water, and every parameter shows 5 seconds.When user's water, sensor is sent the flow pulse signal, pulse of every premium on currency, LED simultaneously
1Once glittering.This pulse signal is from single chip microcomputer IC
1P
3, P
4The mouth input, this mouth is defined as the counter works mode, and after a series of calculation process of microcomputer, storage also shows relevant data.When surplus water reaches the warning limit, closed valve 1 minute, continue to show surplus water later on, remind the user to purchase water as early as possible.The forward purchasing water yield is zero, closes valve and cuts off the water supply.If any two above water meters, this device only turn-offs one the road and supplies water, and all the other is used water as owe water yield record, has later on time-consumingly to deduct automatically.
