Description

Technical Field

[0001] The present invention relates to the technical field of building automation, and specifically to a distributed-based building automation method and an automation system. Background Art

[0002] Building automation refers to the intelligent control and management of air conditioners, ventilation, lighting, elevators, energy, etc. in a building through automation technology; a building automation system usually adopts advanced and stable sensors and control systems to monitor environmental parameters in real time and perform intelligent adjustment according to preset programs or algorithms to achieve an energy-saving, comfortable, and safe building environment; a building automation system is an important part of a smart building and a smart city, which can improve the building operation efficiency and management level and realize the sustainable development of the building.

[0003] Existing methods for building automation are usually used to analyze multiple building areas in a building, divide and collect data for the building areas based on the correlation between every two building areas, so that different building areas can be controlled according to 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 during building control, when the fluctuations of multiple users in the same building area using the building subsystem are large and the fluctuations of the overall subsystem of the building area are small, only through the above method, it is impossible to accurately and sensitively adjust the user's equipment resource input in a timely manner based on the usage fluctuations of the user's subsystem in the building area, resulting in an impact on the user's equipment usage in the building. For example, in the Chinese patent with the publication number CN116319904A, a building automation distributed method and system are disclosed. This solution is to establish an automation system between buildings, receive control instructions sent by the cloud platform through respective communication nodes, test the facilities in the building by means of feedback information, and when the feedback information times out, it is determined that the training fails, and through positioning, the position where the training fails is marked; other improvements for building automation are usually methods in terms of resource collaborative utilization. This method still cannot adjust the user's equipment resource input in a timely manner based on the usage fluctuations of the user's subsystem in the building area, resulting in an impact on the user's equipment usage in the building. In view of this, it is necessary to improve the existing building automation methods. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

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

[0047] The user preference analysis module draws a user scatter plot and establishes a user preference pie chart based on the operating parameters of the subsystems in the building automation system used by the users in the building; the user preference analysis module includes a preference period acquisition unit, a scatter plot drawing unit, and a pie chart drawing unit; the preference period acquisition unit is configured with a preference period acquisition strategy, and the preference period acquisition strategy includes:

[0048] For any user in the building, record the number of days in an electricity consumption cycle of the user in the building as k, obtain the operation parameters of the subsystems in the building automation system used by the user in the most recent k days, and record the operation parameters of each day as usage parameter SC1 to usage parameter SC k , where the subsystems of the building automation system include the air conditioning system, the power system, and the lighting system; in the specific implementation process, in this embodiment, the subsystems of the building automation system analyzed only include the air conditioning system, the power system, and the lighting system. In actual analysis, subsequent analysis can be carried out 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] Analyze the usage parameter SC using the preference cycle acquisition method, and obtain the activity cycle of the user based on the analysis results; the preference cycle acquisition method includes: record the difference between the usage duration of the air conditioning system in usage parameter SC1 and the usage duration of the air conditioning system in usage parameter SC2 as the air conditioning buffer duration; record the difference between the electricity consumption of the power system in usage parameter SC1 and the electricity consumption of the power system in usage parameter SC2 as the electricity consumption buffer amount; record the difference between the lighting duration of the lighting system in usage parameter SC1 and the lighting duration of the lighting system in usage parameter SC2 as the lighting buffer duration; set the cycle value, and initially set the value of the cycle value as z; in the specific implementation process, for example, in one analysis, the usage duration of the air conditioning system in usage parameter SC1 is 12h, and the usage duration of the air conditioning system in usage parameter SC2 is 8h. Then, by calculation, the air conditioning buffer duration can be obtained as 4h; by obtaining the air conditioning buffer duration, the electricity consumption buffer amount, and the lighting buffer duration, it is helpful to use them as the judgment criteria for the activity cycle when obtaining the activity cycle of the user subsequently, so that the obtained user scatter plot and user preference pie chart are more in line with the actual living habits of the user;

[0050] Analyze using the cycle analysis sub-method. The cycle analysis sub-method includes: record the value obtained by dividing k by z and rounding down as J, and record the value of J multiplied by z as k1, where k1 is a positive integer less than or equal to k and greater than 1; record the usage parameter SC1 to usage parameter SC k in the above as the first cycle, record the usage parameter SC z to usage parameter SC z+1 as the second cycle, and so on, to obtain the third cycle to the Jth cycle, where the Jth cycle is the usage parameter SC z+z to usage parameter SC (J-1)×z+1 ; for any J1th cycle among the second cycle to the Jth cycle, for any usage parameter SC J×z in the J1th cycle, (J1-1)×z+z1, obtain the usage parameter SC in the first cycle z1 The usage duration of the air-conditioning system, the power consumption of the power system, and the lighting duration of the lighting system are respectively different from those of the air-conditioning system, the power consumption of the power system, and the lighting duration of the lighting system corresponding to the usage parameter SC (J1-1)×z+z1 , and are respectively denoted as the air-conditioning analysis duration, the power consumption analysis amount, and the lighting analysis duration; when the air-conditioning analysis duration is greater than the air-conditioning buffer duration, the power consumption analysis amount is greater than the power consumption buffer amount, or the lighting analysis duration is greater than the lighting buffer duration, record z as an ineligible value; when the air-conditioning analysis duration is less than or equal to the air-conditioning buffer duration, the power consumption analysis amount is less than or equal to the power consumption buffer amount, and the lighting analysis duration is less than or equal to the lighting buffer duration, record the usage parameter SC (J1-1)×z+z1 as a cycleable parameter, where z1 is a positive integer less than or equal to z and greater than or equal to 1, and J1 is a positive integer less than or equal to J and greater than or equal to 3; when all usage parameters SC in the J1-th cycle are recorded as cycleable parameters, record the J1-th cycle as a repeated cycle; when the third cycle to the J-th cycle are all recorded as repeated cycles, record the cycle value as the user's activity cycle; in the specific implementation process, in this embodiment, set the initial value of z to 2, that is, the minimum value of the cycle value is 2, then in the analysis process of the cycle analysis sub-method, k is 30 and z is 2, and through calculation, J is 15, so the first cycle is from usage parameter SC1 to usage parameter SC2, the second cycle is from usage parameter SC3 to usage parameter SC4, and so on, the 15th cycle is from usage parameter SC 29 to usage parameter SC 30 ; when z is recorded as an ineligible value, it means that when z is used as the user's life cycle, there will be a large difference in the usage of one of the subsystems in a certain cycle compared with the first cycle, so z cannot be used as the user's life cycle;

[0051] When the cycle analysis sub-method records z as an ineligible value, stop the subsequent analysis of the cycle analysis sub-method, add 1 to both the cycle value and z, and then use the cycle analysis sub-method for analysis again; when J is 1 for the first time in the analysis process of the cycle analysis sub-method and the cycle value has not been recorded as the user's activity cycle at this time, stop the subsequent analysis of the cycle analysis sub-method, and set the user's activity cycle to g, where g is a positive integer less than k and greater than 1; in the specific implementation process, in this embodiment, based on the cycle of normal working days and rest days, set g to 7, and the value of g can be replaced in actual analysis to fit the user's actual life cycle.

Among them, t1 is a positive integer less than or equal to t and greater than or equal to 1; in the specific implementation process, for example, in an analysis process, the calculated total equilibrium value is 3500, and JH t1 is 300, then it can be calculated that the degree of the sector corresponding to the pie region BQ t1 is 30.8°. By obtaining the degrees of the sectors corresponding to each pie region BQ based on the equilibrium value, the proportion of each pie region BQ in the pie chart can fit the user's activity cycle, which helps subsequent analysis.
