This paper introduces the global Internet of things (IoT) market in recent three years, analyzes the development direction and core obstacles of the IoT, expounds the latest relevant scientific research, compares the key technologies of low-cost IoT, and finally takes the digital management needs of electrical equipment in the headquarters building of Shenghui Holding Co., Ltd. as an example to create a model for energy conservation and emission reduction of manufacturing enterprises enabled by IoT technology.

Based on the IOT technology, the oil separator room monitoring system has been designed and implemented. In the sensing layer, the sensor with ZigBee wireless transmission function is in-charge of the collecting of the parameters around the oil separator. The serial device serves trans-coding and transmit the running data of the separators. Video surveillance system is designed and installed in the separator room in order to to achieve remote visualization management. In the network layer, ZigBee Ethernet gateway receive the information from the sensor, and send it to network switch. On the application layer, the comprehensive operation platform software of oil separator room was designed to summary, process and present the monitoring information, and to realize the man-machine visualization interface of the monitoring system of oil separator room. The system is installed on the ship, and has achieved better results. It has laid a certain practical foundation for the design of the ship engine room of the Internet of things.
