1.项目概述 Project Overview

本项目位于上海浦东，建设本套系统是为了对油漆车间用电、工业用水、冷水、热水、天然气、压缩空气等用能实时在线监测，并对车间上述用能情况按照产线、工艺流程、生产班组、用途进行精细化计量和分析，实现车间的用能分类、分项统计分析，实现车间产线用能考核、工艺段用能考核、班组用能考核，从而实现车间精细化管理。

This project is located in Pudong, Shanghai. The purpose of this system is to monitor the energy consumption of the paint workshop in real time, such as electricity, industrial water, cold water, hot water, natural gas, compressed air, etc., and to measure and analyze the energy consumption of the workshop according to the production line, process flow, production team and purpose, so as to realize the classification and sub item statistical analysis of the energy consumption of the workshop and realize the production of the workshop Line energy use assessment, process section energy use assessment, team energy use assessment, so as to realize the refine management of workshop.

4.解决方案 Solution

本项目我司提供了Acrel-5000能耗管理系统。整个系统采用环网式结构，同时从采集层、传输层、管理层全部实现双机热冗余设计，在实现车间内部展示的同时实现数据上传给厂区能源管理大平台。

系统主要实现的监控功能：

综合能耗展示：反映车间当年用能各分类能耗和折算为标准煤的综合能耗，

能耗比较：反映某分类能耗当日及昨日同期、当月及上月同期、当年及上年同期的用能及对比，增长百分比及增加值；

展示方式：统计支路用能的日、月、周、季、年用能，统计数据可通过柱状图、点线图、堆积图、饼图等多种图表展示；

In this project, our company provides Acrel-5000 energy consumption management system. The whole system adopts ring network structure, and realizes dual machine thermal redundancy design from the acquisition layer, transmission layer and management layer. It can realize the internal display of the workshop and upload the data to the plant energy management platform.

The main monitoring functions of the system are as follows:

Comprehensive energy consumption display: it reflects the comprehensive energy consumption of each category of energy consumption of the workshop in the current year and converted into standard coal,

Energy consumption comparison: reflect the energy consumption and comparison, growth percentage and added value of a certain category of energy consumption on the same day and the same period of yesterday, the same period of current month and last month, the same period of current year and last year;

Display mode: the daily, monthly, weekly, quarterly and annual energy consumption of branch road can be counted, and the statistical data can be displayed by bar chart, point line chart, accumulation chart, pie chart and other charts;
