The Guangdong Province key project "Dongben Integration" invested and constructed by Dongfeng Honda Automotive Parts Co., Ltd. will be completed in the Daya Bay Area of Huizhou. The total investment of this project is 4.5 billion yuan, with a construction area of 420000 square meters for 1.5 to 2 million complete vehicle supporting parts products. Dongben proposed to achieve an annual increase of 10% in sales revenue, taxes, and employee salaries during the 13th Five Year Plan period; By 2020, the business goal is expected to exceed 4 billion yuan, with taxes and fees reaching 400 million yuan, actively fulfilling the company's social responsibility. Collaborating with companies like Dongfeng Honda, which have a strong sense of social responsibility, is in line with the corporate culture of Sfere.
Jiangsu Sifel Electric Co., Ltd. adheres to the core values of helping customers create value, sharing value with employees, and contributing value to society. Together with Dongfeng Honda, we are helping intelligent chemical plants accelerate transformation and upgrading.
SF Electric relies on a modern management system, advanced process equipment, and efficient information management systems to provide customers with the most valuable cooperation platform through excellent research and development, high-quality products, and comprehensive services.
At present, the third phase of Dongfeng Honda Company has been launched, with the goal of completing the overall relocation by September 2019. At that time, Dongfeng Honda will fully build a modern green project that integrates "casting, forging, and machining", with a production capacity of 2 million vehicles per year. Sfere Electric has tailored a stable, reliable, and technologically advanced power monitoring system for Dongfeng Honda, and has integrated intelligent instruments, electrical fire monitoring, and intelligent control devices in the intelligent factory to ensure the smooth operation of the project.
In the new factory of "Dongben Integration", the intelligent power monitoring system and electrical fire monitoring system of SF Electric are used.
The intelligent power monitoring system and electrical fire monitoring system are relatively independent systems with their own independent hardware and operating software. They can also upload data to the higher-level management platform through network connection, achieving data sharing.
The products that Speer helped with
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.
design basis
Project Configuration
Install multifunctional power instrument PD194Z-9HY and comprehensive protector on the circuit of the distribution cabinets in each distribution room where power monitoring instruments need to be installed on the drawings, monitor the current and voltage of individual circuits in real time, and then connect them to the communication management machine in each distribution room.
After the completion of the system, the communication management machines in each distribution room are pulled to the main control room of the main building through optical converters, and all monitoring data is transmitted to the background 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.
The overall network acquisition structure of this system is based on the fiber optic TP/IP network communication between each distribution room and 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 photoelectric conversion between optical fibers and various management devices.
The underlying network consists of RS485 communication cables between instruments, protection equipment, etc., which are laid using dedicated twisted pair cables. As the communication management machine is configured in their respective sub stations, RS485 transmission distance is all 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 functions
It can automatically collect and intelligently manage the electrical energy information of various metering points in the high-voltage and low-voltage distribution rooms of the entire plant, ensuring that the distribution network operates in a safe, reliable, high-quality, and efficient optimal state; Realize 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, alarm and monitoring of the protected electrical circuit can be achieved, and it can be uploaded 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, indicating the alarm location. At the same time, the on-site detector emits an audible and visual alarm and control signal to remind users to investigate or replace hidden circuits, reducing the risk of fire caused by electrical reasons.
Sfere Electric focuses on comprehensive electrical applications and aims to become a top expert in electrical application solutions. Our vision is to better serve China's intelligent factories and fulfill our corporate social responsibility.
