Embodiment 1

[0027] A 3G network-based smart home smart meter wireless meter reading system, the smart meter 2 meter reading system can realize the meter reading work of the smart meter 2 in a residential area or even multiple residential areas.

[0028] The smart meter 2 meter reading system includes a meter box, smart meter 2, MSP430F149 microprocessor, Si4432 module 6, concentrator and central processing unit. The meter box is installed in the households of the community, and each meter box is equipped with a smart meter, a MSP430F149 microprocessor and a Si4432 module. A smart meter corresponds to a MSP430F149 microprocessor, and a MSP430F149 microprocessor corresponds to a 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.

[0029] The electric meter box is fixedly installed on the wall body 6 through a bracket. The bracket includes a bracket body, the b...

Embodiment 2

[0036] On the basis of the first embodiment, the height adjustment mechanism includes an adjustment bolt 53 installed on the support part 5 and an adjustment nut 54 matched with the adjustment bolt 53 .

[0037] When in use, the meter box is first installed on the wall 6 through the installation part 4, and the bottom of the meter box is placed on the support part 5, so that the bottom of the meter box is matched with the top of the adjusting bolt. After adopting the above installation method, the meter box is improved. The stability of the installation is high; the height position of the meter box is adjusted by turning the adjusting bolt 53 . By setting the above structure, it not only ensures the stability of the installation of the meter box, but also makes the installation of the meter box safe and reliable. Measurement accuracy.

Embodiment 3

[0039] On the basis of Embodiment 1 or Embodiment 2, the support part 5 includes a vertical plate 51 and a horizontal plate 52, the vertical plate 51 is connected with the installation part 4 as an integral structure, and the end of the horizontal plate 52 and the end of the vertical plate 51 The part is integrally formed, and the vertical plate 51 and the horizontal plate 52 form a "T" shape structure. The number of height adjustment mechanisms is set to three, one of which is installed on the vertical plate 51, and the other two height adjustment mechanisms are installed symmetrically. It is arranged at both ends of the horizontal plate 52 , and three height adjustment mechanisms cooperate on the supporting part 5 to form an isosceles triangle structure. With the above structure, the horizontal plate 52 and the vertical plate 51 cooperate to form a "T" shape, which makes the supporting effect of the support part 5 better and ensures the stability of the meter box.
