Card welding matter.But the instrumenter also there are fraction can not also carry out another side after the inserting device wave soldering of one side
Wave-soldering, can only use artificial manual welding, not only increased man-hour length but also increased processing cost, welding relatively low there are production efficiency
The problems such as second-rate.
In order to solve the problems, such as that existing electric energy meter circuit plate is of high cost, so selection drops this from PCB circuit board aspect, therefore row
Industry is designed progressively from multilayer PCB circuit board to single board design, and the scheme taken in the prior art is：Using mainboard, power panel
With three modules of liquid crystal board, three pieces of pcb boards are respectively prepared, carrying out assembling by power panel, mainboard and liquid crystal board completes electric energy meter
Communication and display, needed in assembling winding displacement or row pin connection, Assembling Production efficiency is low, of high cost.Therefore according to existing
Technology, three pieces of pcb boards are made by electric energy meter, are communicated by assembling, workshop, which often produces one piece of plank, needs winding displacement or row
Pin connects, low production efficiency, and major loop can influence the work of RS485 circuits, it is therefore desirable to a kind of compact-sized, cost of exploitation
The low and high electric energy meter circuit plate of production efficiency.
Utility model content

Table production efficiency, reduces the board structure of circuit of the electric energy meter of printing pcb board cost.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of board structure of circuit of electric energy meter,
Including microprocessor, and power module, memory, LED display unit, clock unit, the channel radio being connected with microprocessor
Believe unit, infrared interface, Ethernet, USB interface, further include the RS485 interface circuits with microprocessor signals electrical isolation, its
It is characterized in that：The circuit board of the electric energy meter includes mainboard and platelet, the microprocessor, memory, clock unit, channel radio
Letter unit, infrared interface, Ethernet and USB interface are installed concentratedly in mainboard, and RS485 interface circuits are installed on independent
On platelet, and it will be hung over outside platelet on mainboard, power module is installed on mainboard.
As an improvement, the LED display unit is installed on mainboard, and is guided on electric energy meter shell and shown by light-guiding pillar
Show.
As an improvement, the platelet for being provided with RS485 interface circuits is welded on mainboard by stamp hole mode.
Further, the space length being provided between the platelet and mainboard of RS485 interface circuits is at least 6.5mm.
Specifically, the microprocessor is high-performance CM3 microprocessors.
Specifically, the wireless communication unit includes GPRS or cdma wireless communication network.
Specifically, backup power supply and single phase alternating current power supply are further included in the structure, by backup power supply and single-phase alternating current
Source is connected with power module respectively, is microprocessor power supply by power module.
Specifically, the infrared interface other end is connected with palm PC and IR remote controller, the microprocessor output
End is communicated by infrared interface with handheld device.
Compared with prior art, the utility model has the advantage of：The RS485 circuits for needing to isolate are concentrated on into platelet
On, and be fixed on by way of hanging plate on mainboard, the purpose of isolation is played by space length, while platelet passes through stamp hole
