Through ranking and report results, combined with reward and punishment strategies, KPI indicators, the results of energy consumption rewards and punishments are given. Realize that every employee cares about energy consumption and use performance salary to motivate employees to save energy and reduce consumption.

At the beginning of each heating season, the online energy consumption plan is formulated and decomposed according to the management mode of the enterprise. Reduce workload and improve work efficiency and accuracy.

Classified according to different types of sites, determine energy consumption assessment indicators for each site.

3.2.1 Implement indicators to people

The planned assessment indicators are broken down to each specific station and implemented to specific individuals, as assessment targets for monitoring and guiding heating adjustment. Associate the person in charge of each site with the appraisal plan and assign it to an accurate person in charge.

The corresponding person in charge can log in to the system to see the assessment plan made. Before the beginning of each heating season, the assessment indicators can be confirmed, making management more convenient and avoiding manual errors.

3.3 Real-time tracking

3.3.1 Weather forecast and analysis

Meteorological data is the basic basis for heating dispatch. The system introduces meteorological information to command dispatch and as the basic basis for measuring heat consumption. In the meteorological data management, three functional modules are provided: meteorological status, meteorological forecast and meteorological data statistical analysis.

3.3.2 Statistical analysis of energy consumption

The energy consumption of all heat exchange stations is queried according to the granularity of day, week, month, and heating season. The unit consumption ranks TOP10 before and after. The planned heat consumption is compared with the actual heat consumption, and the savings and costs are inquired. Combine queries from different dimensions in time and space.

3.3.3 Real-time energy consumption TOP10 ranking

The heat, water, and electricity energy consumption of the same type of heat exchange stations will be ranked in the top 5 and bottom 5 of the day.

The manager knows the sites with high and low energy consumption at any time, understands the overall operation status, and provides a basis for decision-making.

3.3.4 Early warning of excessive heat consumption

The planning index of each site is broken down to every hour as the theoretical planning value. Convert the accumulated heat collected in real time into the same unit as the planned index for comparison. If it exceeds the limit, prompt it. The administrators corresponding to the sites are aware of the sites whose energy consumption exceeds the standard in time, and respond in time to achieve real-time energy saving.

3.3.5 Scheduling adjustment suggestions

Realize the linkage between dispatch and energy consumption system, energy consumption guide dispatch adjustment, and achieve real-time energy saving.

For sites with excessive heat consumption, the system analyzes the reasons for the exceeding, and based on the analyzed reasons, gives scheduling adjustment suggestions and pushes them to the corresponding administrator. The person in charge of each station makes adjustments and responses based on the suggested suggestions and the actual situation, supervises the implementation of the plan, and implements energy saving and consumption reduction.

3.3.6 Analysis of water loss in heat exchange station

Perform data analysis on the data collected by the water replenishment meter in a heat exchange station to determine the water loss of the station in a certain period of time. Judge whether the water replenishment volume exceeds the standard and whether the water loss of the station is within the allowable range, and it can be displayed through the water replenishment curve at the same time. For the person in charge of the site to analyze the leakage and water stealing of the pipe network. Anticipate leakage failures in advance.

Site energy consumption trend analysis helps administrators analyze a single site and locate problems. You can query the trend of outdoor temperature change, heat consumption, water consumption, power consumption, water consumption, electricity consumption, and heat consumption within a time period.

Based on this function, the person in charge of the site can verify the pros and cons of previous adjustments, and combined with weather forecasts, can provide a basis for future adjustments.

3.4.5 Section Super Analysis

According to historical energy consumption data, form daily, monthly, and heating season reports. It not only reflects the savings in water, electricity, and heat, but also reflects the cost value of the savings.

As the basis for energy consumption assessment, find the corresponding administrator and implement the assessment policy.

3.5 Performance appraisal

3.5.1 Monthly assessment

According to the water, electricity, and heat consumption of each station, the excess cost, the excess cost and the energy saving cost will be settled every month, and reward and punishment measures will be implemented to the specific responsible person.

Fines according to the cost exceeding the standard; reward the specific person in charge according to the energy saving cost

The appraisal system guides all employees of the company to care about energy conservation and truly take measures for energy conservation.

3.5.2 Assessment of heating season

At the end of each heating season, count the accumulated value of all stations in the entire heating season, deduct the previous monthly rewards or penalties, and conduct energy consumption assessments throughout the year based on the principle of more refunds and less compensation. It is also energy-saving rewards and penalties for exceeding standards.

3.6 Heat source energy consumption analysis

Combined with historical outdoor temperature, the heat supply and unit consumption of all heat sources are compared and analyzed. Compare according to week, month and year.

According to the daily measured parameters, the air consumption, water consumption, electricity consumption and heat consumption of each heat source and the whole network are counted, and various costs are calculated, and the daily whole network energy consumption statistics report is generated to provide basis and reference for the production department to do heat source scheduling.
