At present, the third phase of Dongfeng Honda Company has been launchedThe goal is to complete the overall relocation by September 2019. At that time, Dongben will comprehensively build a modern green project that integrates "casting, forging, and machining", with a production capacity of 2 million complete vehicles per year. Sifei Electric has tailored a stable, reliable, and technologically advanced power monitoring system for Dongfeng Honda, and integrated intelligent instruments, electrical fire monitoring, and intelligent control devices into the intelligent factory to ensure the smooth operation of the project.

inIn the new factory of "Dongben Integration", Sifei Electric's intelligent power monitoring system and electrical fire monitoring system are used.

The intelligent power monitoring system and electrical fire monitoring system are relatively independent systems with their own hardware and operating software, and can also upload data to the higher-level management platform through network connection to achieve data sharing.

The software and hardware equipment included in the intelligent power monitoring system; The software and hardware equipment included in the power monitoring system; The electrical fire monitoring system includes software and hardware equipment, and has completed the connection, installation, and debugging of the monitoring equipment.

Project Configuration

Design multifunctional power meters on the circuits of the distribution cabinets in each distribution room that require the installation of power monitoring instruments on the drawingsPD194Z-9HY and integrated protector monitor the current and voltage of a single circuit in real time, and then connect them to the communication management machines in their respective distribution rooms.

After the system is completed, the communication management machines in each distribution room are pulled to the main control room of the main building through optical fibers via photoelectric converters, and all monitoring data is transmitted to the backend of the power monitoring system.

Other devices with digital communication interfaces, such as transformer temperature control equipment, DC equipment, analog screens, etc., require data to be uploaded to the backend computer for remote monitoring or control.

Network topology diagram

The overall network acquisition structure of this system is based on the use of optical fibers in each distribution roomTP/IP network communicates with the main control room of the main building to complete centralized data collection and processing.The network is divided into upper layer network and lower layer network.The upper layer network refers to the Ethernet (or fiber optic Ethernet) from each substation to the control center. Industrial grade fiber optic transceivers are used for optoelectronic conversion between optical fibers and various management devices.

The underlying network is the communication between instruments, protection devices, and other equipmentRS485 communication cables are laid using dedicated twisted pair cables. As the communication management machines are configured in their respective sub stations, the RS485 transmission distance is within the sub stations, and there will be no long-distance signal interference or attenuation issues. The on-site equipment layer of the network mainly includes measuring instruments, protective devices, etc., which are installed locally in the corresponding switchgear, have local operation functions, and are not affected by remote computer start stop.This system is divided into three layers from bottom to top: device terminal layer, network communication layer, and system management layer.

implement functionality

Automated collection and intelligent management of energy information for various metering points in the high-voltage distribution room and low-voltage distribution room of the entire factoryTo ensure the optimal operation of the distribution network in a safe, reliable, high-quality, and efficient stateRealize remote measurement, control, and management of the distribution network,To meet the needs of electricity safety, energy management, and energy conservation and consumption reduction.

By monitoring parameters such as residual current and load current in the circuit,Realize alarm and monitoring of protected electrical circuits, and upload them to the fire monitoring system for centralized control and management.When the relevant parameters in the circuit are abnormal, the monitoring equipment emits an audible and visual alarm to indicate the alarm location. At the same time, the on-site detector emits an audible and visual alarm and control signal to remind the user to investigate or replace the hidden danger line,Reduce the risk of fire caused by electrical reasons.

Sifei ElectricTaking comprehensive electrical applications as the development center and building Sifei Electric into a top expert in electrical application solutions as the corporate vision, we aim to better serve China's smart factories and fulfill our corporate social responsibility.
