Data verification, namely, for data acquired by a sensor, the system needs to perform preliminary verification, such as detecting the integrity and accuracy of the data, and removing noise data or unreasonable data points according to a certain rule, for example, when the sudden increase of the energy consumption of a certain device is detected but the state of the device is not changed, the system can judge that the false alarm of the sensor is possible.
1.5 Storage and processing preparation of data
The local storage is that all the collected real-time data are locally stored on the edge computing equipment, so that the data loss caused by the network problem is avoided;

Carbon emissions generated by gas consumption are converted by heat value such as "gas usage amount×gas heat value×carbon emission factor=carbon emission amount";
The carbon emission factors of different equipment and energy types can be preset and flexibly adjusted based on the actual energy structure in the building.

If the energy consumption of the device is found to be mismatched (i.e., energy inefficient operation) with its intended output, the system will record this. For example, air conditioning may increase energy consumption due to insufficient maintenance, but the cooling effect is not improved accordingly.
And the fault early warning is that the edge equipment can also identify possible fault conditions of the equipment by analyzing the historical operation data of the equipment. For example, the system may detect a sudden increase in energy consumption of a device while its output performance decreases, thereby inferring that the device may need to be serviced or replaced.

Meanwhile, the building management system can adjust the running state of the equipment according to the advice. For example, certain high energy consuming devices may be turned off remotely or the temperature and illumination in the area may be dynamically adjusted.
Dynamic feedback and continuous optimization, namely, the system continuously tracks the implementation effect of feedback and adjusts the operation strategy of the equipment in real time. For example, if the system suggests optimizing the air conditioning temperature in a region and carbon emissions drop after execution, the system will record this information and use it as a basis for future decisions.
Wherein:
The energy efficiency analysis standard is refined, namely different devices have different energy efficiency standards, and the edge computing device can formulate individualized energy efficiency standards for different devices according to different device types and different running environments, so that the accuracy of analysis results is ensured.

5.4 Future carbon emission prediction
And the time period prediction is that the cloud end can predict the carbon emission of a certain time period in the future based on the historical carbon emission data of the building. For example, by analyzing the data from the previous years, in combination with real-time energy consumption, weather and building usage, the cloud can predict the carbon emissions for the next week or month and provide optimization advice to the manager.
Decision support and intelligent optimization, the cloud can give decision support according to the prediction result, and the cloud can recommend to adjust the running time or power of some equipment to reduce carbon emission. For example, the system may recommend reducing the operation of certain high energy consuming devices prior to the predicted peak carbon emission period, thereby controlling the carbon emissions in advance.
In order to avoid the influence of data uploading delay on system decision, an asynchronous communication mode can be adopted between the cloud end and the edge equipment, when a network has a problem, the edge equipment automatically caches data, and the data is uploaded in batches after the network is recovered.
