Description

technical field [0001] The invention relates to a power consumption information collection module based on HPLC power line carrier communication technology, which belongs to the field of power consumption information collection. Background technique [0002] At present, most of the existing domestic power user meter reading systems use 485 wiring, narrow-band low-frequency power line carrier or wireless communication methods for the local communication from the meter or collection terminal to the meter reading concentrator. These meter reading systems or It is because the amount of construction is too large and it is inconvenient to implement on a large scale (such as 485 wiring); or it is greatly affected by the load characteristics of the power line, which causes the communication channel to be unstable and unreliable (such as narrow-band low-frequency power line carrier). Their common weaknesses are all It is because the bandwidth is too narrow, the rate is too low, the r...

[0002] At present, most of the existing domestic power user meter reading systems use 485 wiring, narrow-band low-frequency power line carrier or wireless communication methods for the local communication from the meter or collection terminal to the meter reading concentrator. These meter reading systems or It is because the amount of construction is too large and it is inconvenient to implement on a large scale (such as 485 wiring); or it is greatly affected by the load characteristics of the power line, which causes the communication channel to be unstable and unreliable (such as narrow-band low-frequency power line carrier). Their common weaknesses are all It is because the bandwidth is too narrow, the rate is too low, the real-time performance is poor, and two-way fast communication cannot be realized. Therefore, the practicality of the existing system is low, and it cannot meet the needs of the power supply company to build an integrated collection platform for electricity consumption information, let alone meet the requirements of electricity prepayment. Higher-level management requirements such as bills, power interruption and restoration, and power theft prevention
