The system successfully enters the main page. The main page displays the building picture of the building, the basic information of the building, the electricity pie chart of the building in the month and the consumption of various energy sources. According to the selected building, the building picture is loaded, you can choose time to check the building energy consumption, select the building or time to automatically refresh, the default is the day.
The system can query the energy usage according to the branch name of the classified energy consumption, and display the energy peak of the current day and the current month (the maximum demand value of the electric energy), the energy used for the day, the energy used in the current month, the energy used in the current year, and the energy used in the same period of the previous year. Comparing the energy consumption during the same period of the month and the energy consumption in the same period of the previous year; displaying the energy consumption of the past 48 hours, 31 days, 12 months, and 3 years in a histogram; showing the load energy trend of 15 minutes in a graph (electric meter display) The power curve, the flow meter shows the flow rate curve) and shows the current value, the maximum and minimum values within 15 minutes.
The system can count the usage of each branch in a certain period of time, day by day, week by month, month by month, quarter by season and year by year. Select the branch that needs to be queried, click ‘Load Data’ to view the trend of energy usage of each branch. You can query according to the existing date or custom time, and you can display the total output of the tributary by chart.
The Acrel-5000 energy management system can perform energy consumption statistics and display according to sub-items. Among them, the daily sub-item can display the daily and yesterday energy consumption histograms of different sub-items (blue bars indicate today, green bars indicate yesterday); use energy pie chart to show the energy consumption of each sub-item in the past 31 days The stacked chart shows the energy consumption trend of each item in the past 31 days; the itemized energy ranking chart shows the top 10 branches of the selected item corresponding to the energy consumption value.
The system can count the usage of each sub-item day by day, week by week, month by month, quarter by season and year by year. Select the branch that needs to be queried, and ‘Load Data’ to view the trend of energy usage of each branch in the sub-item, which can be queried according to the existing date or custom time. The branches here are all based on the configuration of the classification items in the basic data. The default query is the energy consumption of the current month.
The system can perform energy consumption statistics and display according to the sub-items. Among them, the day-on-year analysis chart shows the bar chart of the comparison of the energy consumption values of the departments on the same day and yesterday (the blue bar indicates today, the green bar indicates yesterday); the pie chart shows the energy consumption ratio of each department in the past 31 days; The energy consumption trend of each department in the past 31 days; the department performance appraisal comparison chart shows the actual energy consumption and energy use target value. When the actual energy value is greater than the target value, the actual value is marked as red.
