Linkage control system and method applied to intelligent building

The invention relates to a linkage control system and method applied to a smart building, in particular to a heterogeneous subsystem of a smart building management platform, so that the devices can be controlled and operated effectively.

Since the introduction of the concept of smart building, system integration has always been an extremely important issue. In the system integration project, automation is one of the indicators of building intelligence, and linkage control is an important function of automation. At present, the device linkage control on the market is mostly limited to the devices controlled under the same system. If the devices between the independent and heterogeneous systems are difficult to be linked due to their high complexity. There are many factors to be considered in the inter-system device linkage. For example, the card reader of the access control system and the camera of the image monitoring system need to be associated with each other. Linkage control also needs to avoid action conflicts and can not operate effectively. For example, situation 1: The linkage of a safety automation is set as follows: 1. A door of a restricted area is swiped in, and the camera immediately turns to the A door and records. 2. The B door of a restricted area is swiped in, and the camera immediately turns to the B door and records. However, when the doors of A and B are swiped at the same time, conflicts will arise. Scenario 2: There is a temperature sensor, air conditioner and power window in a conference room. When the temperature of the conference room exceeds 28 degrees, the temperature sensor is connected to the air conditioner to lower the temperature, and the temperature sensor is also connected to the power window. As a result, the gas of the air conditioner is leaked to the outside and wastes. In the case of the conventional single system linkage control technology, if the above situation 1 and the situation 2 are allowed to be solved through the setting, but the multiple systems cannot be satisfied, the device linkage between the systems can be effectively operated without conflict.

On the other hand, the linkage setting is the association setting between devices. If the device data is inconsistent or the linked data is inconsistent, the linkage failure will be invalid, or even the wrong linkage. Therefore, in system integration, synchronization mechanisms are often used to enhance data consistency. And correctness. However, conventional techniques are often used in a fixed manner. For example, during a certain period of time, synchronization is required regardless of the need for synchronization. If this method is synchronized during the linkage, it will cause a linkage error and be in multiple systems. Integration also consumes bandwidth and system performance.

It can be seen that the above-mentioned conventional methods still have poor system availability, which is not a convenient and widely applicable design and needs to be improved.

The main object of the present invention is to provide a linkage control system and method for intelligent building, which utilizes a smart building management platform to manage heterogeneous subsystems, so that subsystems managed by the intelligent building management platform can cross each other across systems.

A linkage control system and method for intelligent building that achieves the above object is developed by a smart building management platform, including a device list synchronization mechanism, a smart linkage data setting mechanism, and a linked data synchronization mechanism, and the like. The inventory synchronization mechanism refers to whether a device between the intelligent building management platform and the subsystem needs to be synchronized with reference to a certain weight to avoid synchronization at a time when synchronization is not suitable and to ensure data consistency, and the weight will be based on the database. The data status, device list synchronization time, device importance, device transaction rate and other factors are dynamically adjusted.

The intelligent linkage data setting mechanism refers to entity association analysis and assigns priority value and mutual exclusion relationship when setting subsystem device linkage data. In the case of entity association, the system equipment of the above situation 1 and situation 2 can be analyzed as many-to-one. And one-to-many relationship, the former mainly uses the priority value of the linked data to avoid linkage conflicts, and the latter mainly uses the mutual exclusion relationship to make the devices that conflict with each other in operation It works.

The subsystem operates independently and manages the complex array device and is set by linkage. The subsystem device is divided into a linkage source device and a linkage device, wherein the linkage source device is a trigger device of the linkage start, and the linkage device is a device triggered by the startup device.

A linkage control method applied to a smart building is to use a synchronous weight method to determine the timing of data synchronization, and to analyze the linked data by entity association, and assign a priority value and a mutually exclusive relationship, which mainly include: a, device list synchronization mechanism, Using the weight judgment method to determine the synchronization timing of the equipment data, so that the intelligent building management platform and the subsystem synchronization operation does not affect the linkage operation; b, the intelligent linkage data setting mechanism is to set the subsystem equipment linkage In the case of data, the linked data is judged to be linked by the entity; c. The linkage data synchronization mechanism determines the synchronization timing of the linked data by the weighting method, so that the intelligent building management platform and the subsystem are synchronized. Does not affect the linked work.

The step of the device list synchronization mechanism comprises: Step 1: The smart building management platform checks the status of the device list stored in the database, and adjusts the device synchronization weight according to the check result; Step 2: If the smart building The management platform needs to be synchronized with the subsystem immediately, which requires the instruction to increase the device synchronization weight.

Please refer to FIG. 1 , which is a structural diagram of a linkage control system and method applied to a smart building according to the present invention. The main components thereof include a smart building management platform 1 , a common integration platform for heterogeneous subsystems of the management system, and a smart building management platform. 1 includes a web server 11, an application server 12, and a database server 13. The web server 11 mainly provides a website service, wherein the linkage setting module 111 provides a user linkage setting service, and the device maintenance module 112 provides a user. The service of the subsystem device is mainly used for data processing and subsystem interfacing, and includes a device management module 121, a device synchronization module 122, a linkage execution module 123, a linkage synchronization module 124, and data. The library management module 125, the device management module 121 processes the instructions of the device maintenance module 112, transmits the device transaction data to the subsystem group 2, and receives the device data transmitted by the subsystem group 2, when the subsystem group 2 When the device changes, the transaction data can be immediately transmitted to the module, and the device synchronization module 122 mainly processes the smart building. The building management platform 1 and the subsystem group 2 device work synchronously, and the device management module 121 handles the immediate data transaction, although the smart building management platform 1 and the subsystem group 2 data are consistent, but the time may be long A certain factor causes the data to be inconsistent with each other. The device synchronization module 122 mainly strengthens the maintenance of the device data, solves the problem of inconsistent data, and the linkage execution module 123 processes the command of the linkage setting module 111, and analyzes the linkage setting data, and sets the linkage. The data will be immediately transmitted to the subsystem group 2, and the linked synchronization module 124 mainly processes the linked data synchronization operation between the smart building management platform 1 and the subsystem group 2. The linked execution module 123 can reach the intelligent building management platform 1 and the child.

After setting, the linkage source device and the linkage destination device are separated, and the linkage source device 211 can be linked with the linkage device 212 of the system or the linkage device 222 of the subsystem B22. Similarly, the linkage source device 221 can be linked to the linkage device 222 of the same system. Or the device 212 of the linkage of the subsystem A21.

Please refer to FIG. 2 , which is a flowchart of a device list synchronization mechanism applied to a linkage control system and method of a smart building according to the present invention. As can be seen from the figure, the device synchronization weight value is the most important part of the synchronization mechanism, and the calculation formula is: The relevant parameters of Ws=Wt×(Du+De+Ts1) are as follows: Ws: device synchronization weight value; Wt: time weight, the time for each subsystem to synchronize is not necessarily the same, the closer to the appropriate synchronization time, the higher the value, if If the linked operation is in progress, the value will be immediately lowered, and resumed after the end of the linked operation; Du: device usage rate, the more frequently the device is used, the higher the value; De: device transaction rate, the more frequent the device changes, the higher the value; Ts1: device synchronization interval value, between 0 and 1, from the last device synchronization The farther the time, the higher the value.

The calculation basis of the device synchronization weight value Ws is mainly when the device usage rate is high, the device transaction rate is high, or the device synchronization interval is too long, and the synchronization operation is performed at the synchronization time, and the intelligent building management platform and one of the subsystems are used. The equipment list synchronization mechanism steps are as follows: Step 1: The smart building management platform checks the equipment list status 301 stored in the database, and the status data includes: group data such as device transaction record and device usage frequency; step 2: check through the device list status After 301, according to the result, the parameters of the device usage rate Du and the device transaction rate De are adjusted to adjust the device synchronization weight value. Step 3: If the intelligent building management platform needs to be synchronized with the subsystem immediately, the smart building management platform takes the initiative to the child. The system sends a synchronization request 302, which requires the instruction to modify the time weight Wt and the device synchronization interval value Ts1 to increase the device synchronization weight; step 4, if the subsystem wants to synchronize with the smart building management platform 303, the subsystem can transmit relevant parameters to Smart building management platform, whose parameters include synchronization time, synchronization type, Group information available information. After receiving the relevant parameters, the intelligent building management platform modifies the time weight Wt and the device synchronization interval value Ts1, and increases the device synchronization weight 304. Step 5: The intelligent building management platform periodically checks whether the device synchronization weight is greater than the target value 305, and the target The default value of the value is the average of the device synchronization weight value Ws multiplied by 2 in the past period of time, but can also be adjusted up and down according to the demand. If the device synchronization weight is not large For the target value, record the check time and modify the parameter of the device synchronization interval value Ts1; Step 6. If the device synchronization weight is greater than the target value, it starts the device synchronization job 307. If the synchronization fails 308, the failure record will be Modify the device synchronization interval value Ts1 to determine whether synchronization needs to be performed again. If the synchronization is successful, the parameters are modified to return to the preset value, and the synchronization job 309 is ended.

Please refer to FIG. 3 , which is an intelligent association analysis diagram of the intelligent linkage data setting mechanism applied to the linkage control system and method of the smart building according to the present invention. It can be seen from the figure that after the linkage of the intelligent building management platform, the subsystem equipment room is Can be divided into many-to-one, one-to-many and one-to-one relationship, equipment A 401, equipment B 402 and equipment C 403 for many-to-one relationship, a total of 2 groups of linkage settings data, equipment 404, equipment 405 and equipment 406 is a one-to-many relationship, a total of two sets of linkage settings data, device Geng 407 and device Xin 408 are one-to-one relationship, a total of 1 group linkage setting data, each group of linkage setting data mainly includes: linkage source device, linkage purpose device, The linkage state, the priority value, and the mutual exclusion relationship are the linked trigger devices. For example, device A 401, device B 402, and device 404, and the connected device is the device triggered by the initiating device, for example: Device C 403, device 405 and device 406, the linked status indicates whether the linked operation is completed, the priority value is the priority order of the linkage, and the mutual exclusion relationship is that the actions conflict with each other. For example, when the air-conditioning and the opening of the window are operated at the same time, the conflict will be caused, that is, the mutual exclusion relationship. If the linkage source device has multiple devices and there is only one device connected to the target device, it is a many-to-one relationship. The linked source devices are mutually exclusive, and the order of priority is determined by the priority value. For example, the linkage purpose of the linkage source device A 401 and the device B 402 is the device C 403. If the device A 401 is linked to the device C 403 priority The value is higher than the priority value of the device B 403, and when the device A 401 and the device B 402 are simultaneously triggered or triggered, the device A 401 can interrupt device B 402 and perform the linked operation preferentially. If the priority values of the linkage settings are the same, it is completed in the order of trigger time. When the setting is linked, if there is only one source device and there are multiple devices connected to the target device, For a one-to-many relationship, the destination device determines the order of the triggers based on the priority value. The mutual exclusion relationship determines which linked devices cannot operate at the same time. The linked devices are not all mutually exclusive. For example, the device 404 is linked. The device 405 and the device 406 are in a mutually exclusive relationship, and the device 405 and the device 406 are in a mutually exclusive relationship, and the priority value of the device 405 is higher than the device 406, so the device 404 triggers the device 405 and the device 406, and the device 405 After the device 406 is triggered, since the device 405 and the device have mutually exclusive relationship, after the linkage operation of the device 405 is completed, the device 406 starts to operate, and if the device 405 and the device 406 are not mutually exclusive The relationship between the two devices can be operated at the same time, the device gh 407 linkage device Xin 408 its situation is relatively simple, when the device gh 407 linkage device Xin 408, the device Xin 408 will start to operate.

Please refer to FIG. 4 , which is a diagram of a linkage control system and method applied to a smart building according to the present invention. It can be seen from the figure that the linkage synchronization weight is the most important part of this synchronization mechanism, and its calculation formula is Wg=Wt×(De+Fg+Gf+Ts2). The relevant parameters are as follows: Wg: linkage synchronization weight value; Wt: Time weight, the time for each subsystem to synchronize is not necessarily the same, the closer to the appropriate synchronization time, the higher the value, if the linkage operation is in progress, the value will be immediately lowered, and then resumed after the end of the linked operation; De: device turnover rate The more frequent the device is, the higher the value is; Fg: the triggering frequency, the more frequent the triggering, the higher the value; Gf: the failure rate of linkage, the more the number of failures, the higher the value; Ts2: the synchronization interval value, between Between 0 and 1, the farther from the last synchronization time, the higher the value.

The calculation basis of the linkage synchronization weight value Wg is mainly when the device transaction rate When the high, interlocking trigger rate is high, the linkage failure rate is high, or the synchronization synchronization interval is too long, the synchronization operation is performed at the synchronization time. Taking the subsystems of the intelligent building management platform and the subsystems of the connected source equipment and the equipment of the linked purpose equipment, the steps of synchronizing the linked data are: Step 1: The intelligent building management platform checks the linked data 501 stored in the database, and the linked data includes: Group data such as device change record, linked trigger frequency, linkage failure rate, and linkage status; Step 2: After checking 501 through linked data, adjust the device transaction rate De, the linkage trigger frequency Fg, and the linkage failure rate Gf according to the result, to modify Synchronization weight 505; Step 3: If the intelligent building management platform needs to be synchronized with the subsystem immediately, the intelligent building management platform actively sends a synchronization request 502 to the subsystem of the linked source device and the subsystem of the linked destination device, and the request instruction will be modified. The time weight Wt and the linkage synchronization interval value Ts2 make the linkage synchronization weight increase; Step 4: If the subsystem of the linkage source device wants to synchronize with the intelligent building management platform 503, the subsystem can transmit relevant parameters to the intelligent building management platform, and its parameters Including synchronization time, synchronization type, linkage purpose The subsystem group data. After receiving the relevant parameters, the intelligent building management platform modifies the time weight Wt and the linkage synchronization interval value Ts2 to increase the linkage synchronization weight 505; Step 5: If the subsystem of the connected device wants to synchronize with the intelligent building management platform 504, the child The system can transmit relevant parameters to the intelligent building management platform, and its parameters include group data such as synchronization time, synchronization type, and subsystem of the linkage source device. After the smart building management platform receives the relevant parameters, it will modify the time right. The weight Wt and the linkage synchronization interval value Ts2 are used to increase the linkage synchronization weight 505; Step 6: The intelligent building management platform periodically determines whether the linkage synchronization weight is greater than the target value 506, and the preset value of the target value is the linkage synchronization in the past period of time. The average value of the weight value Wg is multiplied by 2, but it can also be adjusted up and down according to the demand. If the linkage synchronization weight is not greater than the target value, the judgment time is recorded to modify the linkage synchronization interval value Ts2; step 7. If the linkage synchronization weight is greater than the target value, it starts to synchronize the synchronization operation 508, and if the synchronization fails 509, This failure record will modify the linked synchronization interval value Ts2 to determine if synchronization is required again. If the synchronization is successful, the parameters are modified to be restored to the preset value, and the synchronization job 510 is ended.

The detailed description of the present invention is intended to be illustrative of a preferred embodiment of the invention, and is not intended to limit the scope of the invention. The patent scope of this case.

To sum up, this case is not only innovative in terms of technical thinking, but also has many of the above-mentioned functions that are not in the traditional methods of the past.
