Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 2, the utility model power load management system, the first network serial server 2 that comprise the office terminal 1 that is installed in the building, is positioned at the office terminal outlet side and first power line carrier modem 3, be installed in the antenna 4 of building outside, by feeder line 5 and antenna 4 mutually near radio station 6, second power line carrier modem 7 that is positioned at radio station 6 input sides and the second network serial server 8 of setting.Be connected by the power line 9 in the existing building between first power line carrier modem 3 and second power line carrier modem 7.
In the present embodiment, the first network serial server 2 is connected with office terminal 1 by the RS-232 Serial Port Line, forms signal modulation local area network (LAN) based on ICP/IP protocol between first power line carrier modem 3 and the first network serial server 2.Equally, the second network serial server 8 is connected with radio station 6 by the RS-232 Serial Port Line, forms signal demodulation local area network (LAN) based on ICP/IP protocol between second power line carrier modem 7 and the second network serial server 8.Be connected by the power line 9 in the existing structure between the first power line carrier modulator 3 and the second power line carrier modulator.This power line is fixed voltage transferring electric power line, i.e. no any transformer between it, thus guarantee data-signal smooth transmission thereon.The radio station for from existing load management terminal, removing, radio station 6, in the present embodiment, frequency of radio station is 230MHz, it arranges near antenna 4, like this, its with antenna 4 between only need short feeder line just can realize constructing to be connected.
Be illustrated above-mentioned the utility model Radio-Controlled Load Device is formed, and will analyze its principle and the course of work below:
We know, in the prior art, the radio station is mounted in load management terminal inside, and terminal is got in touch with by RS-232 serial ports and radio station, and the radio station externally transmits by feeder line again.In the present embodiment, the radio station that originally was installed in the office terminal is shifted out and is installed near near the antenna, be equivalent to like this RS-232 serial ports between office terminal and the radio station is extended to antenna side, needs are changed in so corresponding signal transmission.Present embodiment is based on the TCP/IP local area network technology and carries out signal conversion transmission, set up signal modulation local area network (LAN) by the first network serial server 2 and first power line carrier modem 3 are set at the office terminal outlet side, its signal that is used for the office terminal is sent is modulated to the power line carrier signal and is loaded into power line 9; By second power line carrier modem 7 being set and the second network serial server 8 is set up signal demodulation local area network (LAN) at the radio station input side, it is used for being demodulated into the radio station from the power line carrier signal that power line 9 receives and receives signal.Concrete, when office terminal 1 needs to send data, data send to first power line modem 3 by the first network serial server 2, after 3 modulation of first power line modem, be loaded on the power line 9, power line 9 is under the prerequisite that guarantees normal transmission of electricity, data-signal after the modulation is inputed to second power line modem 7, second power line modem 7 carries out data corresponding demodulation and inputs to the second network serial server 8, the second network serial server 8 will receive data and reduce, thereby be sent to radio station 6 by corresponding serial ports, realize that terminal sends to the data of main website thereby radio station 6 sends to antenna 4 by feeder line 5 with data.Equally, when main website sent data to terminal, the processing of its data was corresponding substantially with said process, does not repeat them here.
