Description

Technical Field

[0001] The present invention relates to the technical field of control systems, and in particular to a building automatic control system based on a digital platform. Background Art

[0002] In today's digital age, building automation systems have become one of the core technologies in the field of building management. Building automation systems are based on advanced information technology and integrate the management and control of different subsystems to achieve comprehensive monitoring and intelligent control of buildings. They can not only achieve efficient use of building energy, but also improve building safety and comfort, creating a better office experience for tenants and employees. With the continuous acceleration of urbanization and people's pursuit of high-quality life, smart buildings will be more and more widely used. As a core component of smart buildings, building automation systems will have a wider application prospect.

[0003] Chinese Patent Publication No.: CN116774635A, discloses a building automatic control system based on a digital platform, including a data acquisition module and a data analysis module. The data acquisition module is used to collect fire information on each floor in the building, and the fire information includes at least smoke concentration and floor temperature. The data analysis module is used to analyze the fire information and select the escape method of the trapped personnel according to the fire information, and generate corresponding escape instructions according to different escape methods. The escape instructions include escape instructions and avoidance instructions. It can be seen that the building automatic control system based on the digital platform of the above scheme realizes that when a fire occurs, by obtaining the smoke concentration and floor temperature of the current floor, the best preferred escape route is provided for the personnel on each floor. However, the above scheme cannot identify and count the personnel to clarify the elevator operation scheduling to complete the elevator preparation in advance, and thus cannot guarantee the efficiency of personnel transportation during peak hours. Summary of the invention

The building automation system based on the digital platform according to claim 4 is characterized in that: The analysis unit is further used to send a main elevator single-row mode notification based on the load floor position when it is determined that the operation of the main elevator does not meet the transportation demand due to the existence of a load floor, and determine the scheduling demand of the secondary elevator based on the total number of people waiting for the secondary elevator; wherein the load floor is the floor with the largest number of waiting people, and the total number of people waiting for the secondary elevator is the total number of people at each exit of the secondary elevator in the same transportation interval as the main elevator.

6. The building automation system based on a digital platform according to claim 4 is characterized in that: The analysis unit is also used to send a statistical cycle duration notification when it is necessary to re-determine the reason why the operation of the main elevator does not meet the transportation demand, and to re-determine the reason why the operation of the main elevator does not meet the transportation demand based on the statistical total duration of a single cycle transportation of the main elevator, and to send corresponding notifications to the control unit based on the determined reasons, including: a secondary elevator scheduling demand notification and a main elevator single-row mode notification.

7. The building automation system based on a digital platform according to claim 4 is characterized in that: The analysis unit is also used to send a secondary elevator scheduling demand notification when the main elevator does not meet the transportation demand due to insufficient load of the main elevator, and increase the scheduling ratio based on the total number difference, and the increase in the scheduling ratio is proportional to the total number difference; wherein the total number difference is the difference between the total number of waiting people and the preset total number of people, and the mobilization ratio is the ratio of the number of one-way running secondary elevators in the same transportation range as the main elevator to the total number of secondary elevators.

8. The building automation system based on a digital platform according to claim 7 is characterized in that: The analysis unit is also used to determine whether the scheduling meets the transportation demand based on the difference in scheduling personnel on the load floor after the scheduling demand is completed, and to determine the additional scheduling ratio of elevators in different transportation intervals based on the personnel difference when it is determined that the scheduling does not meet the transportation demand, or to re-determine whether the scheduling meets the transportation demand based on the difference in scheduling personnel on other floors; wherein the difference in scheduling personnel is the difference between the total number of waiting personnel on the load floor and the total number of waiting personnel on the load floor after scheduling.

9. The building automation system based on a digital platform according to claim 8, characterized in that: The analysis unit is also used to re-determine whether the scheduling meets the transportation demand based on the additional scheduling personnel difference, and to determine the additional scheduling ratio of elevators in different transportation intervals based on the personnel difference according to the judgment result; wherein the additional scheduling personnel difference is the difference between the total number of waiting personnel on the other floors and the total number of waiting personnel on the other floors after scheduling.

10. The building automation system based on a digital platform according to claim 9, characterized in that: The analysis unit is also used to increase the amplitude of the additional dispatching ratio of elevators in different transport intervals based on the total personnel difference, and the increase amplitude of the additional dispatching ratio is inversely proportional to the total personnel difference, and to send a rejection notice when it is determined that the total personnel difference is greater than a preset total personnel difference; wherein the total personnel difference is the sum of the dispatching personnel difference and the additional dispatching personnel difference.
