AI Technical Summary

Technical Problem

The heterogeneous communication protocols of modules in industrial and commercial energy storage cabinets and large storage container systems lead to tangled and chaotic wiring harnesses. Traditional wiring methods require independent laying of communication cables, resulting in a large number of cables and long wiring time.

Method used

It adopts PLC communication, using the power line as the communication medium. The communication channel is established with the coupling transformer through the PLC master node module and slave node module. It supports the IEEE1901.1 PLC standard and OFDM orthogonal multi-carrier technology to realize dynamic adaptive multi-node MESH networking. Each module communicates through hardware protocols such as UART, CAN, and GPIO.

Benefits of technology

This reduces the number of communication cables in the system, shortens wiring time, and improves communication stability and flexibility.

Abstract

The utility model discloses an industrial and commercial storage system based on a PLC communication mode, comprising a power supply module which is connected with at least one PLC master node module and a plurality of PLC slave node modules. The PLC main node module is connected with an EMS system through a UART and a GPIO, and the GPIO serves as an emergency response port. The plurality of PLC slave node modules are respectively and correspondingly connected with a plurality of functional modules; a coupling transformer is installed between the PLC master node module and the plurality of PLC slave node modules and the power line, and is used for establishing a communication channel with the power line. Existing power cables are used as communication media, the mode of one module and one wiring of a traditional energy storage system is thoroughly changed, the number of communication cables in industrial and commercial storage equipment is suddenly reduced, and the wiring time is greatly shortened.
