Today, I will introduce a national invention authorized patent-a smart gas meter with electronic temperature and pressure compensation. The patent was applied for by Shanghai Zhenlan Instrument Technology Co., Ltd., and the authorization was announced on February 8, 2017.
Content descriptionThe utility model belongs to the technical field of gas meters, and relates to the application of electronic temperature and pressure compensation and prepaid IC card to implement stepped gas prices in smart gas meters, specifically, a smart gas meter with electronic temperature and pressure compensation functions.
Background of the inventionWith the development of urban gas business and the improvement of people’s living standards and the rapid growth of gas residents, at the same time, with the rapid development of science and technology and the diversification of gas life, the difficulty in reading membrane gas meters in households and gas With the change of temperature and pressure, the difference between the same product and different quality and the realization of the national stepped gas price and gas management policy, ordinary IC card meters can no longer fully meet the needs of gas users, electronic temperature and pressure compensation function stepped billing IC card gas meters Start the new pace of gas life, make the metering standard, accurate, billing staged, and stepped.
Summary of the inventionThe purpose of the present invention is to provide a smart gas meter with electronic temperature and pressure compensation functions to solve the above-mentioned problems in the background art.
In order to achieve the above object, the present invention provides the following technical solution: a smart gas meter with electronic temperature and pressure compensation functions, characterized in that: the smart gas meter includes a protective casing, and a temperature and pressure sensor is provided in the protective casing The module, the metering movement, the motor valve is arranged above the metering movement, the metering movement, the motor valve, the temperature and pressure sensor module and the protective casing constitute the complete gas meter, and the complete gas meter is fixedly connected with a base, on the base Installed with an intelligent control module, a counter and a sealing ring, the counter is arranged above the intelligent control module, the intelligent control module is equipped with a liquid crystal display, the intelligent control module is connected to the lithium battery, and the upper surface of the protective casing is provided with an upper cover The upper cover is provided with a battery box and function buttons, an alkaline battery is installed in the battery box, the intelligent control module is connected with the alkaline battery installed in the battery box, and the upper cover and the base are sealed and matched by a sealing ring.
As a further solution of the present invention: the intelligent control module has a step-by-step billing function, and data transmission is performed through the contact 4442 logic encryption IC card and the gas meter intelligent control module. The temperature and pressure sensing module is an embedded temperature and pressure sensor, and the temperature and pressure sensor and the valve line are glue-sealed as a whole and then electrically connected with an external gas meter control module. The temperature and pressure sensing module has a circular thread. The smart gas meter also includes a gas meter control module, a temperature and pressure sensor module, a valve control module, a liquid crystal display module, a sampling module, a query module, an IC card reading and writing module, a real-time clock module, and dual power supplies of lithium batteries and alkaline batteries Management module, the gas meter control module is connected with the temperature and pressure sensor module, valve control module, liquid crystal display module, sampling module, query module, IC card reading and writing module, real-time clock module and dual power management of lithium battery and alkaline battery respectively Module connection, IC card reading and writing module and logic encryption IC card connection.
Compared with the prior art, the utility model has the following beneficial effects: the utility model has the function of compensating the volume of the gas used in the gas meter according to the temperature and pressure on the IC card smart gas meter terminal to the volume of the gas standard condition, and setting The function of standard gas price billing and settlement for standard gas consumption, and the function of stepped gas use, that is, the smart gas meter terminal can input the stepped gas price plan formulated by the government and charge according to the stepped price. The utility model converts the gas consumption of the user from the working gas volume to the standard gas volume, standardizes the measurement, and reduces the measurement error of the working condition caused by the different temperature and pressure. This utility model is fair, just and standard in measurement, and is a practical standardized metering stepped billing gas meter urgently needed in the gas market.
The utility model implements stepwise pricing in response to national policies and implementation of residential gas consumption. While it is convenient for users to recharge and purchase gas, the utility model can also use a recharge card to carry a gas price meter. When recharging the meter, the gas price and the amount of gas purchased are brought into Gas meter terminal, the gas meter saves the internal clock through the lithium battery, and the clock goes to the price adjustment date and time table to automatically adjust the price, realizing the terminal stepped billing settlement function; or the recharge card carrying the price adjustment information is inserted after the expiration date, the price adjustment will occur immediately, and the return will be frozen Write the monthly consumption before and after the start of the gas price for the gas charging system to calculate the compensation fee when the price adjustment is overdue, and realize the terminal tiered billing settlement function. The utility model can realize the step billing function in various ways such as monthly ladder and annual ladder, so that gas companies and users can realize the standardized metering step billing of residential gas, which is convenient to use, and is conducive to fair and reasonable gas use. Will have broad market application prospects.
