Embodiment 1

[0017] A smart home gas meter reading system based on a 3G network, the gas meter reading system can realize the meter reading work of gas meters in a residential area or even multiple residential areas. The gas meter reading system includes a gas meter, MSP430F149 microprocessor, Si4432 module, concentrator and central processing unit. The gas meters are installed in the homes of residents in the community, and each household has a gas meter. Each gas meter is equipped with a MSP430F149 microprocessor and Si4432 module. Each Si4432 module can be equipped with a concentrator, or multiple Si4432 modules can be equipped with a concentrator. Multiple concentrators correspond to one CPU.

[0018] The gas meter includes a casing, in which a counter, an inductor, and a sensor identification circuit are arranged. The casing is connected with an air inlet pipe and an air outlet pipe. The air inlet pipe, the gas meter, and the air outlet pipe form a gas supply passage. There is also...

Embodiment 2

[0024] On the basis of Embodiment 1, the inductor is a magnetic block, and the magnetic block is installed on the wheel surface of the head wheel of the character wheel group, and the sensor identification circuit is a switch circuit composed of a reed switch; Whenever the head wheel of the word wheel group rotates one circle, the magnetic block and the reed tube are close to each other once, and the reed tube is acted by the magnetic block to close the switch circuit once, and the volume of the gas is measured by counting and data conversion; In particular, in other embodiments, the sensor and the sensor identifying circuit may also be a metering signal sampling circuit based on infrared sensing technology or laser sensing technology.

Embodiment 3

[0026]On the basis of Embodiment 1 or Embodiment 2, a transmission gear assembly is also provided on the counter frame, and the transmission gear assembly and the dial gear are respectively arranged at the front end and the rear end of the counter frame, and the transmission gear assembly and the dial gear Fixed by shaft connection. The transmission gear assembly drives the dial gear to rotate, and then the dial gear shifts the head wheel of the word wheel group to rotate for one week, then the first driven wheel of the driven wheel group turns over two teeth, and the driven wheel drives the character gear meshed with it. Another character wheel in the wheel set rotates a number, so that multi-stage cooperation realizes counting.

Abstract

The invention discloses an intelligent household gas meter reading system based on the 3G network, and belongs to gas meter reading systems in the technical field of intelligent homes. By means of the intelligent household gas meter reading system based on the 3G network, higher reliability and real-time performance are achieved, and the problem that the installation stability of magnetic steel in a counter of an existing gas meter is poorer can be solved. According to the technical scheme, the intelligent household gas meter reading system based on the 3G network comprises a gas meter, an MSP430F149 microprocessor, a Si4432 module, a concentrator and a central processing unit; an inductor identification circuit in the gas meter is electrically connected with the MSP430F149 microprocessor which is electrically connected with the Si4432 module, the Si4432 module is connected with the concentrator through a wireless network, and the concentrator is connected with the central processing unit through the 3G network. The intelligent household gas meter reading system based on the 3G network is suitable for the intelligent homes.

Description

technical field [0001] The invention belongs to the technical field of smart home, and relates to a gas meter reading system for smart home, in particular to a gas meter reading system for smart home based on a 3G network. Background technique [0002] With the development of modern technology, new requirements have been put forward for the meter reading method of gas meters in smart homes, that is, gas meters and gas meter reading methods are required to have higher reliability, real-time performance and data quality in smart homes. For the convenience of handling, it is necessary to fundamentally solve the troubles caused by the existing household meter reading and charging to users and meter reading personnel, and improve the meter reading efficiency of gas meters. In addition, most of the existing meter reading systems have problems such as short data transmission distance, poor penetrating ability, and high communication bit error rate of the meter reading system. In ad...
