A Transformation of Old Diesel Generator Set Based on Internet of Things

Diesel generator sets are commonly used in all aspects of production and life. However, there are a lot of old-fashioned diesel generator sets that cannot be controlled remotely, which can’t meet the growing unmanned and intelligent demand. This paper introduces a solution of renovation based on the Internet of Things (IoT). A control box including a generator control module (produced by SmartGen company, located in Zhengzhou, China), a PLC (design by Mitsubishi company) and a speed control unit is designed to monitor and control the status of the generator set. The Modbus protocol was used for transmitting measurement data and commands and a user interface was developed in the Kingview configuration software. Field trials were conducted at two sites over 40 kilometers apart and the results met the design objective.
