Method and system for awakening power line communication network by employing expanded ISP (Inter-System Protocol) signal

Abstract

The invention discloses a method for awakening a power line communication network by employing an expanded ISP (Inter-System Protocol) signal. The method comprises the steps as follows: current network equipment in the power line communication network detects whether the expanded ISP signal is received under a standby mode; if the expanded ISP signal is detected within a certain period of time, the current network equipment transfers the expanded ISP signal to a lower-level network equipment in the power line communication network to awaken the lower-level network equipment, and the current network equipment joins in the network to achieve awakening of the current network equipment. Correspondingly, the invention also discloses a system for awakening the power line communication network by employing the expanded ISP signal. According to the invention, the expanded ISP signal is used as an awakening signal of the power line network; the expanded ISP signal is simple in structure, and easy to detect, and supports simultaneous transmission to a certain extent, so that the power consumption under the standby mode can be reduced; the network can be rapidly awakened, and the awakening efficiency of the overall network is improved.

Description

technical field [0001] The invention relates to the field of power communication, in particular to a method and system for waking up a power line communication network by using an extended ISP signal. Background technique [0002] The power line communication network consists of figure 1 as shown, figure 1 It is a schematic diagram of the power line communication network system. The power line communication network includes two parts: the power line meter reading network and the power line home area network (or home area network). The power line meter reading network includes ACC (Access, power line communication module) local end, ACC relay and ACC A terminal, a power line home area network includes a HAN (Home Area Network, home area network) gateway and a HAN terminal. The amount of communication data in the power line meter reading network application is limited. Generally, the data amount of meter reading is less than 1KB, and the communication method is basically in ...
