Problems solved by technology

In practical applications, the concentrator is often installed in the basement in the current power consumption information collection system. There is no GPRS signal here, and there are problems of difficult wiring and unsatisfactory results when using a long antenna. How to use PLC technology to send out the Ethernet port Data coupling to the PLC line and transmission to the master station via GPRS has become a research topic to solve the dilemma

Embodiment Construction

[0014] In order to facilitate the understanding of the present invention, the present invention will be described in detail below in conjunction with the preferred embodiments of the present invention given in the accompanying drawings.

[0015] Such as figure 1 The shown GPRS composite relay device of the present invention oriented to intelligent electricity service includes a near-end device, a relay device and a remote device. The near-end device is connected to the terminal device of the measurement and control terminal or the collection terminal through Ethernet and is used to couple the Ethernet data to the PLC line. The relay device is located between the near-end device and the remote device and has a relay function. It is used to transmit the data on the PLC line to the power distribution or metering master station through GPRS. In the connection mode of carrier transmission, the PLC carrier signal of the near-end device is single-phase or three-phase carrier transmi...

Abstract

The invention discloses a smart power consumption service oriented GPRS composite relay device, comprising a near end device, a relay device and a far end device. The near end device is connected with a terminal device of a measurement and control terminal or a centralized reading terminal through the Ethernet and is used for coupling Ethernet data on a PLC line. The relay device is located between the near end device and the far end device and has a relay function. The far end device is used for transmitting the data on the PLC line to a power distribution or metering master station through GPRS. According to the GPRS composite relay device, the data produced by the Ethernet port of the terminal device is transmitted to a place with a stable GPRS signal through the power line, and the master station is connected in a GPRS mode, so a stable communication function is realized.

Description

technical field [0001] The invention relates to the technical field of power line communication, in particular to a GPRS composite relay device oriented to intelligent power consumption services. Background technique [0002] Power line communication technology, referred to as PLC technology, is a special communication method that uses power lines as an information transmission medium for voice or data transmission. PLC technology can load the high frequency carrying information on the current, and then transmit it with wires, and the adapter that receives the information separates the high frequency from the current and transmits it to a computer or telephone to realize information transmission. In practical applications, the concentrator is often installed in the basement in the current power consumption information collection system. There is no GPRS signal here, and there are problems of difficult wiring and unsatisfactory results when using a long antenna. How to use PL...
