Abstract
The utility model discloses an intelligent water meter which comprises a data acquisition circuit, a microprocessor, a peripheral circuit, a control drive circuit, a power supply circuit and an RS 485 communication circuit, wherein, the data acquisition circuit converts a mechanical signal into an electrical signal; the power supply circuit supplies electric energy to the data acquisition circuit, the microprocessor, the peripheral circuit and the control drive circuit; and the RS 485 communication circuit is connected with the microprocessor and the power supply circuit. The RS 232 communication port can be directly connected with a computer so as to conduct charging operation or be used for conducting data acquisition.
Description
Technical field
The utility model relates to a kind of water metering device that is widely used in student dormitory, office building etc., specifically is a kind of intellectual water meter.
Background technology
At present, the intellectual water meter of prior art does not have communication interface, can not directly carry out the operation of supplementing with money of intelligent electric meter by computing machine, and need be built-in with the card read/write circuit, can read charging information by this card read/write circuit, but, the data in the card carry out single job by computing machine, the card read-write equipment that is connected with computing machine because being staff, the user inserts card that the secondary operation of intellectual water meter reading of data finishes, therefore twice operation is more loaded down with trivial details, and data are easy to generate the mistake of conversion in the reading and writing process.In addition, the intellectual water meter of prior art does not have communication interface, and administrative center can't carry out a complete metering, statistics, analysis to water consumption by computing machine to user's water supply/cut off the water and control.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, can directly supplement with money by computing machine and the intellectual water meter of image data again but provide a kind of.
The technical solution of the utility model is, a kind of intellectual water meter is provided, comprise data acquisition circuit, microprocessor and the peripheral circuit, the control Driver Circuit that mechanical signal are converted to electric signal that connect successively, the power circuit of electric energy is provided for described data acquisition circuit, microprocessor and peripheral circuit, control Driver Circuit, it also comprises the RS485 telecommunication circuit, and described RS485 telecommunication circuit is connected with microprocessor, power circuit.
After adopting above structure, the utility model compared with prior art, the utility model intellectual water meter can directly be connected with computing machine by the RS485 communication interface, can directly load value data be write the utility model intellectual water meter by computing machine, therefore avoided user's secondary operation, simple, the data-switching mistake of having avoided card read-write in twice operation of whole process.In addition, administrative center can carry out a complete statistics, analysis to user's water consumption by computing machine and being connected of intellectual water meter.
As improvement, the utility model also comprises a standby power supply circuit, can use standby power supply to close water supply valve when power circuit causes the intelligent electric meter outage because of extraneous factor, thereby has avoided water supply company can't measure the economic loss that causes because of outage.
