There is no limit to creativity, and the instrument is invented. Today we introduce a national invention patent for authorization - a smart gas meter display terminal. The patent was filed by Anhui Volta Intelligent Technology Co., Ltd. and was authorized to be announced on April 5, 2017.
Description
The utility model relates to the technical field of gas meters, and more particularly to a smart gas meter display terminal.
Background of the invention
The current smart gas meters are equipped with display devices, which are mainly used to display information such as power consumption and payment. However, most of the gas meters currently used are powered by dry batteries, because the gas itself is dangerous, and once it leaks, it is easy to have a fire. Even the explosion. If the existing gas meter is directly connected to the household power source, the electric equipment is easy to generate heat, and there is a large safety risk.
However, with the development of intelligence, smart gas meters will integrate more and more functions. For example, the current display can display a variety of information, and the gas meter has functions such as voltage detection and anti-theft, and the load pressure of the power supply is increasing. Just relying on dry batteries for power supply, each function is difficult to work properly, and it is necessary to constantly replace the battery; but if it only relies on battery power, it has certain security risks, which limits the development of smart gas meters.
In addition, the current gas meter can only display the usage information, payment information, etc., and is often installed in some corners and boxes. Even if there is a payment reminder, the user pays little attention to it, and there are still cases of abating due to arrears. . Therefore, how to improve the delivery rate of information, so that users can pay attention to relevant information in a timely manner, becomes a problem that needs to be considered in the future development of smart gas meters.
For the above problems, the prior art is ubiquitous, for example, the Chinese patent number: ZL201420588512.X, the announcement date: February 25, 2015, the invention name is: wireless local area network intelligent gas meter, the patent discloses a wireless local area network intelligent The gas meter comprises a base watch, a bottom plate, a surface cover, a control circuit board, a counter , a card holder and a Wi-Fi module, wherein the base table has a built-in valve under the air inlet, and a surface cover is arranged on the front surface of the base meter The surface cover is provided with a control circuit board and a battery pole piece; the surface cover is further provided with a counter window, a liquid crystal display window and function buttons; the liquid crystal display window and the function button are mounted on the control circuit board; the control circuit board Wi-Fi modules, supercapacitors and card holders are also provided above; the control board is connected to the built-in valves, counters and DC power via wires. The solution is powered by a supercapacitor. It can be seen that the existing smart gas meter requires further module optimization.
Summary of the invention
The utility model aims to overcome the shortage of the power meter and the single function of the smart gas meter in the prior art, and provides a smart gas meter display terminal. The technical scheme of the utility model sets the gas meter body and the display part separately. The intelligent display terminal has an independent data processing system and a power supply module, which not only reduces the battery load, but also can conveniently view information such as cost and remaining power, and improves the delivery rate of information.

In order to achieve the above object, the technical solution provided by the utility model is: a smart gas meter display terminal of the utility model, comprising an intelligent display terminal and a gas meter body, wherein the gas meter body communicates with the management terminal through a GSM/GPRS communication module And transmitting the data to the intelligent display terminal;
The smart display terminal includes a central processing unit, and the central processing unit is connected with a wireless network receiver, a flash memory chip, a digital-to-analog converter, an audio encoder, a control panel and a display screen, and the central processing unit is controlled by the control panel for information processing. And displayed on the display screen; the smart display terminal is connected to the household power source through the protection circuit; the gas meter body is powered by the battery power source.
As a further improvement of the present invention, the smart display terminal is provided with a USB interface for reading external storage information. A network cable socket is disposed on the smart display terminal and the gas meter body, and the two are connected by a network cable. The display screen is a touch screen, and the display screen is connected to the central processing unit through a touch panel. A suspension hole or a mounting frame is connected to the smart display terminal housing. The gas meter body comprises a gas meter base table, and the output end of the gas meter base table is connected with a sampling module and a microprocessor in turn, and the microprocessor performs data transmission with the management terminal through the GSM/GPRS communication module. A control module is connected to the output of the microprocessor, and the control module is connected to the built-in valve. The microprocessor is a single chip microcomputer.
Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: a smart gas meter display terminal of the utility model, which sets the display module on the traditional smart gas meter and the gas meter body separately. The utility model constitutes an independent intelligent display terminal and a gas meter body, wherein the gas meter body can be powered by a battery, and the intelligent display terminal can directly use the household power source, thereby reducing the load of the battery in the gas meter body, thereby obtaining a longer use time. Moreover, the safety hazard existing in the use of the power source is eliminated; the smart gas meter display terminal of the utility model can be installed in a position that is easy to see in the kitchen, the living room, etc., so that the user can obtain relevant information better; The intelligent display terminal has an independent central processing unit, which can log in to the gas management system for payment, application for maintenance, etc., and also has functions of watching network video, playing music, etc., and has diversified features; a smart gas meter display of the utility model Terminal, the intelligent display terminal is provided with a USB interface, capable of
