Description
Technical field
This utility model relates to a kind of intelligence AMI electric energy meter, is primarily adapted for use in electric-power metering industry.
Background technology
Most ammeters on domestic and international market are all the tops that LCD MODULE is placed on ammeter at present, and therefore GPRS module can be only placed at the middle part of ammeter, and the antenna part of GPRS module is near binding post, or is placed in end cap.This situation can produce problems with:
1, the electromagnetic wave that the alternating source of ammeter produces produces interference to GPRS antenna；
2, GPRS antenna receives and sends the electromagnetic wave computation chip part generation interference to ammeter of signal generation；
3, PCB and metal part have shielding action to GPRS antenna signal, reduce signal intensity.
Summary of the invention
The technical problems to be solved in the utility model is: the problem for above-mentioned existence provides a kind of intelligence AMI electric energy meter, to improve the stability of GPRS antenna signal intensity and metering, reduces the annoyance level to GPRS antenna.
This utility model be the technical scheme is that a kind of intelligence AMI electric energy meter, it includes the housing assembled by base and table cover, it is respectively arranged with PCBA board in this housing, lower PCBA board and GPRS module, it is electrically connected with computation chip and LCD MODULE in described upper PCBA board, it is electrically connected with Switching Power Supply in lower PCBA board, described GPRS module electrically connects with upper PCBA board, in described table cover, position corresponding to LCD MODULE is provided with LCD screen, described GPRS module is positioned at the top of electric energy meter, and its upright projection on base and upper PCBA board, the upright projection dislocation on base of the lower PCBA board；Described LCD screen uses in-mould injection processes in the middle part of electric energy meter.
Described GPRS module built-in aerial, and it is reserved with external antenna interface.
In described table cover, it is hinged with down turnover cover corresponding to the position of LCD screen.
In described table cover, it is hinged with upturning lid corresponding to the position of GPRS module.
The beneficial effects of the utility model are:
1, GPRS module is placed in the top of electric energy meter, and than prior art, its aerial radiation face increases 1/4, and signal intensity improves more than 25%.
2, GPRS module is placed in the top of electric energy meter, than prior art, adds the distance of GPRS antenna and ammeter Switching Power Supply so that it is be disturbed impact and reduce by more than 95%, it is ensured that module communication performance.
3, GPRS module is placed in the top of electric energy meter, makes GPRS antenna away from computation chip part, improve the stability more than 95% of ammeter metering.
4, LCD screen in-mould injection can ensure that sealing property, it is to avoid the fraction defective that ultrasonic bonding brings.
5, the name plate information in down turnover cover can protect table cover and photoelectric communication.

Detailed description of the invention
As shown in Figure 1-Figure 3, the present embodiment one intelligence AMI electric energy meter, it includes the housing assembled by base 1 and table cover 2, is respectively arranged with PCBA board 3, lower PCBA board 4 and GPRS module 5(built-in aerial, and is reserved with external antenna interface in this housing)；It is electrically connected with computation chip and LCD MODULE in described upper PCBA board 3, it is electrically connected with Switching Power Supply in lower PCBA board 4, described GPRS module 5 electrically connects with upper PCBA board 3, in described table cover 2, it is provided with LCD screen corresponding to the position of LCD MODULE, described GPRS module 5 is positioned at the top of electric energy meter, and its upright projection on base 1 misplaces with upper PCBA board 3, lower PCBA board 4 upright projection on base 1, i.e. without PCBA board below GPRS module 5, increase the distance between PCBA board and antenna, reduce the PCBA board interference to antenna；Described LCD screen uses in-mould injection processes in the middle part of electric energy meter.This structure of the present embodiment, add the distance between antenna and Switching Power Supply, computation chip, because square being inversely proportional to of Electromagnetic Interference rate and distance, so Electromagnetic Interference relatively prior art increases, reduce the Switching Power Supply interference to antenna, and antenna sends when receiving signal the interference to computation chip.
In described table cover 2, it is hinged with down turnover cover 6 corresponding to the position of LCD screen, in described table cover 2, is hinged with upturning lid 7 corresponding to the position of GPRS module 5, be used for isolating electric energy meter and the external world, and be designed to lead-sealable actuation and prevent from arbitrarily opening electric energy meter.
