The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Liquid crystal touch screen concentrator, as shown in figure 1, including liquid crystal touch screen 1, ARM development boards 2, data memory module 3,
Clock module 4 and Modem interface circuits 5, liquid crystal touch screen 1 connect ARM development boards 2 by winding displacement, and ARM development boards 2 are distinguished
Connect data memory module 3, clock module 4, Modem interface circuits 5 and power carrier transmission circuit 6, Modem interface circuits
5 connect host computer 7, the connection low-tension network 8 of power carrier transmission circuit 6 by public telephone network.
Liquid crystal touch screen concentrator, as shown in Fig. 2 power carrier transmission circuit 6 includes carrier wave coupler 9, carrier wave coupling
Device 9 can receive the carrier signal of low-tension network 8, and signal is simultaneously passed sequentially through bandpass filter 10, preceding pole and put by carrier wave coupler 9
Big device 11, modem chip 12, buffer 13, wave filter 14 and power amplifier 15 are finally passed back to carrier wave coupler 9,
Modem chip 12 is that SSCP300 low-voltage power lines spread carrier network controller.
The utility model when in use data collection, processing and transmission be all under the control of ARM development boards 2 carry out
's.Data memory module 3 be mainly used in store parameter, variable, the parameter of concentrator itself, responsible ammeter parameter and electricity
Table electricity etc.；Clock module 4 provides time standard for concentrator timing meter reading；Data feedback channel is between concentrator and host computer
Communication line, using public phone network as communication media, will set concentrator to connect when host computer is communicated with concentrator
The telephone number that line is connected；Down going channel is the communication of concentrator and power carrier transmission circuit 6, use using SSC P300 as
The power carrier mode of core carries out meter reading communication, and above-mentioned parameter, variable can be shown by display screen.Lcd touch
Shield 1 display information and interactive environment is provided, above-mentioned unit is connected by winding displacement, winding displacement is used to transmit data.
Power line carrier transmitting-receiving circuit 6 is responsible for the communication with carrier power meter, and multiple power can be received simultaneously and carries communication, often
Power carrier has independent receive-transmit system all the way.Carrier circuit is the core of whole system, and the technical program uses SSC
P300 is used as power line carrier dedicated modulation demodulation chip.Need to coordinate power amplifier 15 and receive loop and could work, carry
It is closely related that the distance of wave communication and periphery circuit design are good and bad, power is small etc..From SSCP300 export signal amplitude it is small, drive
