Specific embodiment
A kind of wireless intelligent water meter of counterflow-preventing detection, uses main control chip STM8L052R8 microcontroller, essentic-water-meter
Part, wireless module control motor and copper ball valve, measure sampling module, and LCD is shown, power management, battery detecting, counterflow-preventing
Detection device；The main control chip STM8L052R8 controller respectively with base table part, control motor and copper ball valve, metering mould
Block, wireless module, power management, motor driving, battery detection, anti-reverse flow detection device etc. are connected.
In addition, anti-reverse flow detection device is three identical tongue tube A, B, C of placement, these three tongue tubes inside water meter
It is able to detect, prevents backflow phenomena in water meter, and being capable of accurate counting.When receiving the signal of rotating forward, single-chip microcontroller is connect
The pulse signal sequence being subject to is to be known that the case where being main story in this way from A → B → C.In the event of from C → B → A arteries and veins
When rushing signal sequence, we can be concluded that backflow phenomena occurs in water meter.When water meter is run, counted by the principle of tongue tube
, a certain amount of water is often flowed through, as soon as tongue tube closure is primary to generate an electric pulse, single-chip microcontroller counting is primary；According to dry spring
The principle and pulse sequence of pipe, we can accurate detection to water meter whether there is backflow phenomena, and according to the letter detected
Breath, we prevent the backflow phenomena in water meter by closing valve without counting or remotely, reduce unnecessary economy to user
Loss.
Water meter measurement module is tongue tube mode, i.e., often passes by for calculating consumed water in metering water meter
0.1m3 counts an electric pulse, in addition, can also prevent the shake in water meter using the pulse of two tongue tubes, accurately counts
Amount.
A kind of wireless intelligent water meter of counterflow-preventing detection shown in FIG. 1, including main control chip STM8L052R8 microcontroller,
Essentic-water-meter part, wireless module, controls motor and copper ball valve, metering module, LCD are shown, power management, and battery detecting is prevented
Adverse current detection device；The main control chip STM8L052R8 controller respectively with base table part, control motor and copper ball valve, metering
Sampling module, wireless module, power management, motor driving, battery detection, anti-reverse flow detection device etc. are connected.
Three tongue tubes are successively set as A, B, C along water (flow) direction by three tongue tubes of device in anti-reverse flow detection device,
When receiving the signal of rotating forward, the pulse signal sequence that single-chip microcontroller receives is to be known that it is main story in this way from A → B → C
Situation.When in the event of from C → B → A pulse signal sequence, we can be concluded that backflow phenomena occurs in water meter, at this time
It can be set in SCM program without counting or directly pass valve makes water meter without counting, to prevent backflow phenomena bring
It influences.
As shown in the figure, LCD display module can be with water surplus in display water-meter, total water consumption, remaining battery power,
Fault message etc., facilitates user query.
Wherein, wireless module can wirelessly upload the information in water meter, can be in master system
The information in user's water meter clearly is obtained, can be very good to manage.
The counterflow-preventing detection intelligent wireless watermeter function description of the utility model, water meter are transmitted using radio as data
Medium has following functions:
1. sampling function of measuring automatically: controller for water meter can automatic collection mechanical water meter metrical information, can be set every
0.1 ton or metering per ton it is primary (reserved base table tonnage sampling application).
2. warning function: when surplus water is with to preset alarm water, controller for water meter turn off watermeter controlling valves into
Row alarm, alarm water are not less than 0, and controller for water meter opens watermeter controlling valves recovery and uses water after purchase water again.Surplus water
It is not related to disconnected watermeter controlling valves for 0, is directly entered overdraw state.If alarm water is set as 0, watermeter controlling valves are turned off,
The slotting key 10S pressure for pinning protective shell of user can open watermeter controlling valves and enter overdraw state.
3. closing valve water cut-off function: water meter must have overdraw function, and after surplus water is finished, water meter does not close water meter control
Valve processed is automatically into overdraw state, and after surplus water is recorded equal to the limit of overdrawn account, controller for water meter will be again switched off water
Table control valve, at this moment only payment purchase water could open watermeter controlling valves to user again.
4. meter-reading function: concentrator set time centralized automatic meter-reading is primary, can copy the water usage data in controller for water meter
It returns, is used for analysis.
5. bug list replaces function: when water meter breaks down, the side of radio meter register can be utilized according to corresponding table number
Data in bug list are copied back and are transferred in new water meter by formula, and the surplus water in bug list after transfer is clear
Zero.
6. valve exception function of measuring: valve breaks down and cannot turn off, and controller will accumulate overdraw water, again
When recharging and paying, controller can reduce the zero passage water of overdraw automatically.
7. unique table number function: each water meter has unique table number controller, and the controller just forms one therewith after opening an account
One corresponding relationship has uniqueness, only just can control the water meter by this table number；The controller will not re-recognize other controls
System.
8. antimagnetic interference function: when with strong magnetic perturbation unrest water meter normal sample, controller energy valve-closing is cut off the water supply, controller inspection
After measuring magnetic disturbance disappearance, valve recovery water can be automatically opened.
9. valve function is closed in battery undervoltage detection: when cell voltage is lower than 1.8V, single-chip microcontroller can issue after detecting to system
System " under-voltage " information, subsequently completes valve-closing.
10. counterflow-preventing detects: in flow detection device anti-reverse in water meter, electric pulse that three tongue tubes A, B, C are received
When signal not instead of A → B → C sequence, C → B → A, so that it may be determined to be backflow phenomena, water meter can without counting or
Valve-closing prevents backflow phenomena.
The process for using of the utility model counterflow-preventing detection intelligent wireless watermeter:
1. controller for water meter, first has to controller for water meter be detected with self-test card in process of production, test water meter
The watermeter controlling valves of controller control whether normally, and whether detect battery voltage detection point correct.
2. after detection, alarm water being arranged to controller for water meter with host computer, supplements lower limit with money, the limit of overdrawn account, preset
Whether water, accumulative water consumption, meter constant, current Almanac, present clock, test pulse of then leaking water metering are correct.
3. can also repeatedly use upper computer software system as needed in production test procedure and be modified.
4. the data in controller for water meter are all emptied initialization, water meter with upper computer software after water meter produces
In factory state.
5. water meter is installed at the scene, encryption key and partition number, this encryption key and subregion are set with master system
Number to sell water management master system corresponding with backstage.In this way guarantee each sell water management system being capable of independent operating.For user
It opens an account and carries out purchase water, user number information is needed to be transmitted in controller for water meter when first time purchasing water.Purchase water water later
Table controller should compare whether user number is identical, and only the identical ability in the user number and controller for water meter in purchase water card is complete
At purchase water.
