This work presents a system and method to improve transmission quality in smart meter networks that use Modbus-RTU. Energy management systems in industries, buildings and urban infrastructure use smart meters interconnected in a network. These systems can demand a great quantity of interconnected devices, which sets down increasing requirements to communication networks in terms of transmission quality and speed. At the plant level, Modbus-RTU is the de facto protocol for the interconnection of electric meters. However, since it was created more than 4 decades ago, this protocol imposes constraints to transmission speed, maximum number of interconnected devices and error detection mechanisms. This proposal is applicable to Modbus-RTU meter networks that need to increase data transmission speed to be integrated into smart metering systems but face problems due to the increase in transmission errors caused by noise and electromagnetic interference in the field bus. The effectiveness of the proposed method to increase the data rate while maintaining reliability is studied, and simulation and experimental results are presented.

错误检测和纠正以提高使用 Modbus-RTU 的智能计量系统的数据速率

这项工作提出了一种提高使用 Modbus-RTU 的智能电表网络传输质量的系统和方法。工业、建筑和城市基础设施中的能源管理系统使用在网络中互连的智能电表。这些系统可能需要大量的互连设备，这对通信网络在传输质量和速度方面提出了越来越高的要求。在工厂级别，Modbus-RTU 是电表互连的事实上的协议。然而，由于它是在 4 多年前创建的，因此该协议对传输速度、互连设备的最大数量和错误检测机制施加了限制。该提议适用于需要提高数据传输速度以集成到智能电表系统中但面临由于现场总线中的噪声和电磁干扰引起的传输错误增加的问题的Modbus-RTU电表网络。研究了所提出的方法在保持可靠性的同时提高数据速率的有效性，并给出了仿真和实验结果。
