Embodiment Construction

[0029] The invention includes a power supply unit, a GPRS monitoring unit, an RS485 monitoring unit, an ESAM monitoring unit and a carrier monitoring unit. The GPRS monitoring unit is connected to the GPRS interface of the electric energy meter collection terminal through the signal input interface, which is used to intercept and collect GPRS communication data, and is also connected to the communication interface of the monitoring master station through the signal output interface, which is used to transmit the GPRS communication monitoring data to the monitoring Master station; the RS485 monitoring unit is connected to the RS485 interface of the electric energy meter to be monitored through the signal input interface, and is used to intercept and collect the RS485 communication data of the electric energy meter. At the same time, the unit is also connected to the communication interface of the monitoring master station through the signal output interface for The RS485 communi...

Abstract

The invention discloses a multipath centralized monitoring meter which comprises a power supply unit, a GPRS (General Packet Radio Service) monitoring unit, an RS485 monitoring unit, an ESAM (Embedded Secure Access Module) monitoring unit and a carrier monitoring unit. Concentrated design for a circuit of a multipath collecting unit is adopted by the multipath centralized monitoring meter; input and output interfaces are unified; the switching and coordination of the concentrator in a power grid system and the signals, such as a TTL signal, a RS232 signal, a RS485 signal and the like of the meter, are realized; and the transmission for different signals is realized. A general chip in the market is taken as the chip of the multipath centralized monitoring meter and a male mould is taken as an outer shell, so that the cost is low; the concentration degree is high, so that a user is convenient to wire and mount; all interfaces are subjected to isolating treatment, so that the tested equipment is effectively protected and the use is safe; and the system is stable, the function is strong and the application scope is wide. The invention effectively solves the problems that different monitors are configured for different signals, the wire is complex, the potential safety hazards are more, and the like. An important firm basis is established for realizing a 'full-collecting, full-covering and full-fee-control' intelligent electric usage information collecting system for a power grid.

Description

technical field [0001] The invention relates to a smart grid device, in particular to a multi-channel centralized monitor. Background technique [0002] At present, the existing scheme adopts the discrete acquisition method, through mutually independent hardware, and uses the RS485 to RS232 adapter to realize the data communication monitoring of the smart meter 485; uses the GPRS module to realize the data communication monitoring of the master station of the concentrator; due to the ESAM module Due to the particularity of the encryption data (a large amount of encrypted data, and the acquisition circuit needs to be isolated), there is no equipment on the market that can realize the acquisition of the ESAM module, which makes it impossible to realize the centralized monitoring of the ESAN module. Now use the centralized monitoring software to manage and analyze the data collected by each part of the discrete equipment as a whole to achieve the purpose of centralized monitori...
