Description
Technical field
The utility model relates to the gas metering technical field, specifically, relates to a kind of combustion gas pre-payment acquisition controller.
Background technology
At present, the gas meter, flow meter that good multi-user uses is all to adopt prepayment mode, need to use acquisition controller charging meter combustion gas integrated flux, but the gas flow that acquisition controller is originally measured is all the gas flow under operating mode, larger with the gas flow deviation under the mark condition, measure inaccurate, and memory space is little, can not satisfy the needs that record IC-card remaining sum, the historical use traffic of non-volatile recording combustion gas, integrated flux, outrange warning etc., also need paper using history of printing record, use inconvenience.
The utility model content
Technical problem to be solved in the utility model is: a kind of accurate measurement, combustion gas pre-payment acquisition controller that the storing history ability is strong are provided.
for solving the problems of the technologies described above, the technical solution of the utility model is: a kind of combustion gas pre-payment acquisition controller, comprise the temperature sampling change-over circuit, the force samples change-over circuit, traffic sampling change-over circuit and IC-card read/write circuit, described temperature sampling change-over circuit, described force samples change-over circuit, described traffic sampling change-over circuit and described IC-card read/write circuit are connected respectively to secondary single-chip microcomputer, described secondary single-chip microcomputer is connected to host scm, described host scm is connected with storer, described host scm also is connected with power circuit, liquid crystal display circuit, key circuit and RS485 telecommunication circuit.
Preferably, the quantity of described storer is two.
Preferably, described host scm also is connected with the GPRS/GSM telecommunication circuit.
After having adopted technique scheme, the beneficial effects of the utility model are:
Because this combustion gas pre-payment acquisition controller comprises temperature sampling change-over circuit, force samples change-over circuit, traffic sampling change-over circuit and IC-card read/write circuit, described temperature sampling change-over circuit, described force samples change-over circuit, described traffic sampling change-over circuit and described IC-card read/write circuit are connected respectively to secondary single-chip microcomputer, described secondary single-chip microcomputer is connected to host scm, described host scm is connected with storer, and described host scm also is connected with power circuit, liquid crystal display circuit, key circuit and RS485 telecommunication circuit.This combustion gas pre-payment acquisition controller in use, temperature, the pressure flow signal of combustion gas are sent to secondary single-chip microcomputer, pass through again the processing of secondary single-chip microcomputer, convert the operating mode flow to mark condition flow, eliminated the deviation of combustion gas operating mode flow with mark condition flow, made the gas flow signal of measurement more accurate.And calculate combustion gas accumulation use traffic, the IC-card information that records with the IC-card read/write circuit is relatively determined the situation that time that the user need to pay dues and user pay dues.And these information are delivered to host scm, then by host scm, it are delivered to storer and store.
Because the quantity of storer is two, increase memory capacity, can satisfy the needs that record IC-card remaining sum, the historical use traffic of non-volatile recording combustion gas, integrated flux, outrange warning etc., no longer needed paper using history of printing record, realized being easy to use without the paper memory storage.
Because described secondary single-chip microcomputer also is connected with the GPRS/GSM telecommunication circuit, make this combustion gas pre-payment acquisition controller have radio communication function.
