Embodiment 1

[0027] A smart home anti-theft 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 6, 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 provided with a MSP430F149 microprocessor and Si4432 module 6 . Each Si4432 module 6 can be provided with a concentrator correspondingly, and multiple Si4432 modules 6 can also be provided with a concentrator correspondingly. Multiple concentrators correspond to one CPU.

[0028] The gas meter includes a housing 1, and the housing 1 is provided with a counter 4, an inductor 51 and an inductor identification circuit 52. The housing 1 is connected with an inlet pipe 2 and an outlet pipe 3. The inlet pipe 2,...

Embodiment 2

[0037] On the basis of the first embodiment, the counter 4 includes a counter frame 41, a character wheel set 42, and a driven wheel set 43 meshing with the character wheel set 42. The counter frame 41 is also provided with a dial tooth 44, so The flower shifting tooth 44 is engaged with the head wheel 45 of the character wheel group, and the driven wheel group 43 and the character wheel group 42 are all installed on the counter frame 41 by the counter 4 shafts. A blind hole 46 is also provided in the axial direction of the head wheel 45 of the character wheel group, and at least one elastic clip is provided at any position on the wall of the blind hole 46 . The blind hole 46 should be arranged on the other side where the axial direction of the character wheel set head wheel 45 meshes with the radial direction of the dial tooth 44 . The axial blind hole 46 of the character wheel group head wheel 45 is circular, and its inside is used for installing magnetic steel. After the f...

Embodiment 3

[0039] On the basis of Embodiment 1 or Embodiment 2, the inductor 51 is a magnetic block, and the magnetic block is installed on the wheel surface of the head wheel 45 of the character wheel group, and the sensor identification circuit 52 is composed of The switch circuit composed of the reed switch; whenever the head wheel 45 of the word wheel group rotates one circle, the magnetic block and the reed switch are close together once, and the reed switch is acted by the magnetic block to close the switch circuit once, and it is completed by counting and data conversion Measure the volume of the gas; it should be noted that in other embodiments, the sensor 51 and the sensor identification circuit 52 may also be metering signal sampling circuits based on infrared sensing technology or laser sensing technology.

Abstract

The invention discloses a 3G network based smart home gas stealing preventing gas meter reading system, belonging to gas meter reading systems in the technical field of smart homes and aiming to provide a 3G network based smart home gas stealing preventing gas meter reading system with higher reliability and real-time property. The problem that the installation stability of magnetic steel in counters of existing gas meters is poorer can be solved. The system comprises gas meters, MSP430F149 microprocessors, Si4432 modules, concentrators and a CPU (central processing unit), wherein an inductor identification circuit in each gas meter is electrically connected with each MSP430F149 microprocessor; each MSP430F149 microprocessor is electrically connected with each Si4432 module; each Si4432 module is connected with each concentrator by a wireless network; each concentrator is connected with the CPU by a 3G network. The gas meter reading system is suitable to use in smart 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...
