一种低压电力用户电能量采集终端

Low-voltage electricity user energy acquisition terminal

Abstract

本实用新型涉及一种低压电力用户电能量采集终端,满足电能量采集系统中采用载波通讯方式采集485接口电子表电能量数据;它公开了包括电源模块(1),载波模块(2),中央处理器模块(3),(RS485)接口模块(4)等几个部分。本实用新型可以将集中器经过载波通道传输的抄收指令转换后,经RS485接口下发给RS485接口电能表,并将电能表返回数据转发给集中器。该设备可以有效的降低集中抄表系统投入,并提高通讯可靠性、稳定性。
The utility model relates to a low-voltage electricity user energy acquisition terminal which achieves the aim of acquiring the electricity energy data of an electricity energy meter with a 485 interface in an electricity energy acquisition system by adopting a carrier communication mode; the low-voltage electricity user energy acquisition terminal comprises a power supply module (1), a carrier module (2), a central processor module (3), an (RS485) interface module (4) and other parts. In the utility model, a concentrator is converted by a copying command transmitted by a carrier channel and then transmitted to the electricity energy meter with the RS485 interface by the RS485 interface and the return data of the electricity energy meter is transferred to the concentrator. With the equipment, the investment on a concentrated meter reading system can be effectively reduced, and the communication reliability and stability are improved.
