At present, intellectual water meter is divided into IC-card water meter, IC Card Water-Instrument, remote transmitting water meter by function, and the electronic module of embedding only possesses simple function.The water meter of difference in functionality assembles different electronic modules, even the water meter of same function, due to base table valve, the difference of battery specifications, the difference of clearing form, also needs to mate different electronic modules.From designing, producing and selling, manage maintenance, various electronic module all needs strict differentiation, has both been unfavorable for mass, standardized production operation, has been unfavorable for again product up-gradation and maintenance.And existing electronic module not yet realizes ladder clearing at table end.

Utility model content

The utility model, in order to solve the problems of the technologies described above, provide a kind of intellectual water meter electronic module, can be assembled in different base tables, have ladder billing function and multiple-working mode.

The utility model is achieved through the following technical solutions:

A kind of intellectual water meter electronic module, comprise PIC16LF1947 microprocessor, PIC16LF1947 microprocessor is submitted interconnection and is connected to Valve controlling and detection module, IC-card interface module and M-Bus communication module, PIC16LF1947 microprocessor is also connected with power management module, metering module, low voltage detecting module, power down pass valve module, LCD display module harmony/light alarm module.

Described metering module, for gathering the flow pulse of water meter.

Described power management module is the adaptive power circuit being suitable for 3.6V ~ 6V voltage range.

Described IC-card interface module comprises self-adaptation IC-card and adaptive RF card.

Compared with prior art, the utility model has following useful technique effect:

The intellectual water meter NEW ADAPTIVE electronic module that the utility model provides, as water metering and office terminal, owing to being designed with Valve controlling and detection module, can be assembled in different base tables, drives the valve of different size, can adapt to plurality of specifications powered battery; Carry out reading and writing data by employing self-adaptation IC-card, radio-frequency card, accurately, pre-payment transaction is convenient in clearing; And in the hibernation mode, IC-card/radio-frequency card puts in place and automatically wakes up, and the communication information is waken up automatically.Meanwhile, by arranging M_BUS communication interface, can remote transmission data message, and wiring is freely, real-time Transmission metering and status information; Therefore, this electronic module having ladder billing function by arranging microprocessor, automatically can complete the calculating of the water rate of stepped water pricing, stores simultaneously and freezes to use water number certificate.The mode of operation of this module both can the amount of being set to control pattern, also can be set to expense control pattern, can according to user's needs, free switch operating state.

Accompanying drawing explanation

Fig. 1 is that the utility model connects schematic block diagram;

Fig. 2 is adaptive power circuit structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

See Fig. 1, a kind of intellectual water meter electronic module, comprise PIC16LF1947 microprocessor, PIC16LF1947 microprocessor is submitted and is connected for the control of water meter valve of multiple different bore and the Valve controlling of detection and detection module, IC-card interface module and M-Bus communication module, PIC16LF1947 microprocessor is also connected with power management module, valve module is closed in sound/light alarm module, low voltage detecting module, power down, LCD display module and the metering module for the flow pulse that gathers water meter.Wherein, described power management module is the adaptive power circuit of the multiple power supply mode in applicable 3.6V ~ 6V voltage range, and as shown in Figure 2, wherein, power supply mode is alkaline battery or lithium battery.

In addition, described IC-card interface module can be 4442 IC-cards or Mifare one radio-frequency card.
