Description

Technical Field

[0001] The present invention relates to the technical field of building automatic control, and in particular to a distributed building automatic control method and automatic control system. Background Art

[0002] Building automation refers to the intelligent control and management of air conditioning, ventilation, lighting, elevators, energy, etc. in buildings through automation technology; building automation systems usually use advanced and stable sensors and control systems to monitor environmental parameters in real time, and make intelligent adjustments according to preset programs or algorithms to achieve energy-saving, comfortable and safe building environment; building automation systems are an important part of smart buildings and smart cities, which can improve building operation efficiency and management level and achieve sustainable development of buildings.

[0003] Existing methods for building automation are usually used to analyze multiple building areas in a building, divide the building areas and collect data based on the correlation between every two building areas, so that different building areas can be controlled based on the characteristics of different building areas during the building automation process, thereby improving the reliability of control. Although this method can perform targeted control based on the characteristics of the building area when performing building control, when the fluctuations in the use of the building subsystem by multiple users in the same building area are large, and the fluctuations caused by the overall subsystem of the building area are small, the above method alone cannot accurately and sensitively adjust the user's equipment resource investment in a timely manner based on the fluctuations in the use of the user's subsystem in the building area, resulting in an impact on the user's equipment use in the building. For example, in the Chinese patent with publication number CN116319904A, a distributed method and system for building automatic control is disclosed. The scheme is to establish an automatic control system between buildings, and receive control instructions sent by the cloud platform through their respective communication nodes, and test the facilities in the building by means of feedback information. When the feedback information times out, it is judged that the training has failed, and the location of the training failure is marked by positioning; other improvements in building automatic control are usually methods for resource collaborative utilization. This method still cannot make timely adjustments to the user's equipment resource investment based on the usage fluctuations of the user's subsystem in the building area, resulting in an impact on the user's use of equipment in the building. In view of this, it is necessary to improve the existing building automatic control method. Summary of the invention

By proposing a distributed building automatic control method and an automatic control system, it is used to solve the problem that in the existing building automatic control method, when the fluctuation in the use of a building subsystem by multiple users in the same building area is large and the fluctuation in the overall subsystem of the building area caused is small, it is impossible to accurately and sensitively adjust the user's equipment resource investment in a timely manner based on the fluctuation in the use of the user's subsystem in the building area, resulting in affecting the user's use of equipment in the building.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example 1, first aspect, please refer to Figure 1 As shown, the present application provides a distributed building automatic control system, including a user preference analysis module, an interval demarcation module and a user system control module;

In actual analysis, subsequent analysis can be performed according to the composition of the subsystems in the actual building automation system; in the specific implementation process, the electricity consumption cycle can be set according to the electricity settlement cycle in the building. In this embodiment, the electricity consumption cycle is set to 30 days, that is, k=30;

[0049] The usage parameter SC is analyzed using the preference cycle acquisition method, and the user's activity cycle is obtained based on the analysis result; the preference cycle acquisition method includes: recording the difference between the usage time of the air conditioning system in the usage parameter SC1 and the usage time of the air conditioning system in the usage parameter SC2 as the air conditioning buffer time; recording the difference between the power consumption of the power system in the usage parameter SC1 and the power consumption of the power system in the usage parameter SC2 as the power consumption buffer amount; recording the difference between the lighting time of the lighting system in the usage parameter SC1 and the lighting time of the lighting system in the usage parameter SC2 as the lighting buffer time; setting the cycle value, and initially setting the value of the cycle value to z; in the specific implementation process, for example, in an analysis, the usage time of the air conditioning system in the usage parameter SC1 is 12h, and the usage time of the air conditioning system in the usage parameter SC2 is 8h, then the air conditioning buffer time can be calculated to be 4h; by obtaining the air conditioning buffer time, the power consumption buffer amount and the lighting buffer time, it is helpful to use them as the judgment criteria for the activity cycle when obtaining the user's activity cycle in the subsequent acquisition, so that the obtained user scatter plot and user preference pie chart are more in line with the user's actual living habits;
