As shown in fig. 2, a building gateway is connected to field controllers of subsystems in a local area network in a designated area, such as a campus or a building, where one field controller can control a plurality of corresponding terminals.

With the increasing scale of buildings, the types of field subsystems are increasing, including sub-service systems such as security management, video monitoring, elevator control management, fire control management, energy management, lighting management and the like, how to realize linkage and cooperation among the subsystems is an important basis for the improvement of the automation and intelligence level of the comprehensive management of the buildings. The following describes a part of the architecture of the integrated building management system of fig. 2.

The application platform layer is generally deployed in a public cloud or a user enterprise network, provides a platform center for background data storage, monitoring, management and integration for each user site imported by the system, and can provide full-system, multi-site and combinable management and service for various users through a unified interface.

Each local business subsystem of the building can be generally widely deployed in a building site according to the category and the requirement of user building business management, and can comprise a security management subsystem, a video monitoring subsystem, a ladder control management subsystem, a fire control management subsystem, an energy management subsystem, an illumination management subsystem and the like; each type of service subsystem is composed of a plurality of field controllers which are deployed in corresponding position areas according to the field coverage area range.

The building gateway is generally deployed in a large-scale building area, has diversified protocol interfaces and flexible automatic discovery, verification and access functions of subsystem equipment for local regional field management and data access gateway equipment, and can establish a data interface mapping relation of each subsystem equipment; the object data synchronous management table can be automatically established by analyzing the business linkage rule; furthermore, the object data synchronization management table can be based on the object data synchronization management table, and the object data synchronization mode among the subsystems related to each linkage service is dynamically managed by combining the characteristics of the subsystem equipment data interface, the real-time requirement and the gateway resource load rate, so that the data interaction and linkage management level of large-scale building multi-service/multi-subsystem is promoted, and the deep fusion of service logic among various building subsystems is promoted.

The embodiment of the application provides a data processing method based on an intelligent building system, a building gateway can automatically complete dynamic construction of data interaction and synchronization mechanisms among subsystems in the building gateway according to the user import requirement, the method can adapt to various docking modes such as gateway centralized or field controller distributed hybrid linkage management deployment and data object active/passive acquisition, and particularly can adaptively adjust a data synchronization mode through self resource load perception, and convenient deployment and high real-time guarantee are provided for multi-service subsystem linkage in a large-scale application scene.

The first embodiment is described in detail below with reference to fig. 1.

As shown in fig. 1, the present embodiment may include the following steps:

step 110, matching object information of the current target device object in a pre-constructed synchronization management table to obtain a matching data record of the current target device object in the synchronization management table, wherein the synchronization management table is generated according to a pre-configured linkage rule configuration table, and the matching data record includes: matching conditions, output equipment objects, operation information corresponding to the output equipment objects and object monitoring types.

In this step, referring to the terminal layer in fig. 2, the field terminal devices/facilities are widely distributed at each site location of the building park, including various terminal devices/implementations, meters, and third party subsystems of the building that perform, switch, control, detection, alarm, sensing, etc. tasks on site.

In the pre-configured linkage rule configuration table, the contents of the linkage rule configuration table of all the equipment objects can be compiled by a user and finally uploaded to the building gateway, and partial contents of the linkage rule configuration table can be sent to the corresponding field controller through the building gateway. The synchronous management table records matching data records of a plurality of equipment objects, and the gateway manages all the equipment objects in a unified way, so that the gateway can obtain different equipment object data in real time or at regular time in the operation process, a target equipment object can be any terminal managed by the gateway or any field controller, and the field controller can carry out data interaction on the state information of the field controller and the gateway, and can also control the terminal to serve as an intermediary of the state information of the terminal, so that the state information of the terminal and the gateway can carry out data interaction.

The following explains the contents that can be recorded in the linkage rule configuration table by an example. The code number definition of each device object can refer to the full-system associated object definition table in fig. 3, and the attribution corresponding to the device object can be directly determined from the code number of the object, and the attribution corresponding to the device object comprises the system and the controller where the device object is located. Fig. 3 may be automatically generated by the gateway through the information of the linkage rule configuration table.

Meanwhile, as the types of the building subsystems are various, the service control functions and the data interaction interface characteristics of different subsystem devices can have great difference, and if the field controller of the brand subsystem has no fire-fighting linkage function, fire-fighting linkage needs to be newly added in the building gateway, and the field controller of the brand subsystem has consumption linkage, so that the building gateway does not need the fire-fighting linkage function; in addition, the inter-access characteristics of each subsystem data interface are also greatly different, and if data are actively uploaded, data are passively read, so that the adaptability of the traditional gateway in the aspects of linkage function deployment and data docking is insufficient. Fig. 3 may also indicate the number of internal communication interfaces, and the interface determination may be performed according to the interface number shown in fig. 3 when data interaction is performed.

Illustratively, when a business manager defines a linkage rule as: when the outdoor environment temperature of the building site a is lower than the target temperature T1 (for example, 27 ℃), or the total energy consumption of the building area B exceeds the warning value Emax (for example, 500000kwh), the air-conditioning operation mode of the building site a is automatically switched to ventilation (that is, no cooling is performed) (that is, the state is switched from the cooling state C to the ventilation state F). Setting the environment temperature code of the building site A as S1N1P1, and representing a site A sensing acquisition value P1 of a site controller S1N1 to which an environment management subsystem S1 belongs; the total energy consumption code of the building area B is set to be S2N3P6, and the total energy consumption code of the area B of the site controller S2N3 to which the energy management system S2 belongs is represented as P6; the building site air-conditioning operation mode A is represented by S3N5P5, and represents the site air-conditioning operation mode P5 of the site controller S3N5 to which S3 belongs. Then, in the linkage rule, the input object factors include S1N1P1, S2N3P6, and the linkage trigger condition may be expressed as: (S1N1P1< T1) | (S2N3P6> Emax), the output object is S3N5P 5: F.

the matching data record is according to the content of the linkage rule, and can match the linkage rule of the target equipment object in the linkage rule configuration table by determining the object information of one of the equipment objects, such as the code number, and the like, and finally determine the matching condition, the output equipment object, the operation information corresponding to the output equipment object, the object monitoring type and the like in the linkage rule in which each object code is located.

Step 120, obtaining the state information of the target device object.

In the step, the building gateway can firstly realize the unified management of each subsystem, complete the data interaction and synchronization between the gateway and each subsystem, and serve as the basis for the linkage of each subsystem.

The following steps are the process steps that each subsystem is accessed into the building gateway to realize the interaction with the building gateway:

(1) after each subsystem device is started, adding the same default multicast protocol;

(2) the gateway sends a new device adding query frame to the multicast according to a fixed period, the query frame carries unicast reply interface parameters (such as protocol type, port number and the like), after each subsystem device receives the query frame, whether the subsystem device is added into the building gateway or not is checked, the subsystem device which is not added into the building gateway returns a query response frame containing the interface parameters of a self transmission layer to a gateway unicast interface, and the device which is successfully added does not reply;

(3) the querying for the transport layer interface parameter carried in the response frame in step (2) may include: subsystem and device numbers, transport layer protocols and access validation parameters, such as transport protocol class (TCP, transmission control protocol, or UDP, user datagram protocol) and port number, encryption/authentication (e.g. AES, advanced encryption standard) and key, check mode (e.g. CRC, cyclic redundancy check), etc.;

(4) the gateway verifies and connects the transmission layer link access according to the parameter content of the transmission layer interface parameter of the corresponding subsystem equipment carried by the received query response frame, and if the verification is successful, the new transmission layer interface is used for sending an adding confirmation frame carrying the multicast address of the corresponding subsystem to the equipment to be added;

(5) after the joining-intending device receives the joining-in confirmation frame, the joining-intending device sends a confirmation success response frame carrying the object resolution protocol parameter to the gateway;

(6) after receiving the response frame of successful confirmation replied by the device, the gateway defines the configuration of the content resolution protocol corresponding to the device according to the response frame of successful confirmation, and establishes the device data interface mapping relation table of fig. 4, wherein the device data interface mapping relation table comprises: the internal communication interface code is a code naming rule containing three-level affiliation, such as C _ S1N1, the internal communication interface code represents a data interface of node equipment N1 in the subsystem S1, the docking equipment code represents a corresponding site controller code, the transport layer interface parameter includes a transport layer protocol (such as TCP/UDP), a transport protocol parameter (such as a port number of 5000, check ═ CRC), an encryption/authentication parameter (such as AES, or MD5, fifth version of a message digest algorithm), and the content resolution protocol parameter includes an object extraction resolution protocol (such as JSON/XML, etc.) and an object resolution protocol parameter.

Through the process, the building gateway establishes contact with each subsystem, and establishes the equipment data interface mapping relation table of fig. 4 for subsequent data acquisition and data push.

In addition, the field controller is an access device of field terminals of various service subsystems of the building, generally has abundant field buses and input/output interfaces, and can finish data acquisition, storage and uploading and local control of various terminals; generally, the interaction modes of the data interfaces of the field controllers of different brand manufacturers may be different, and are represented as follows: data synchronization from the field controller to the gateway, wherein some supports are actively inquired from the gateway to the field controller, and some supports are actively uploaded from the field controller to the gateway; data synchronization from the gateway to the field controller, active pushing from the gateway to the field controller and active query from the field controller to the gateway are supported.

In one embodiment, the target device object includes a target controller, and step 120 includes:

and receiving the state information uploaded by the target controller.

In this step, the gateway passively receives the state information uploaded by the target controller, where the state information may be actively uploaded to the gateway by the target controller after obtaining the state information of the terminal controlled by the target controller, that is, the state information of the terminal is received by the gateway at this time. In addition, the state information can also be the state information of the target controller actively uploading the state information to the gateway.

In one embodiment, matching the data records further comprises: timing the read cycle, step 120 includes: and if the state information uploaded by the target controller is not received in the timing reading period, requesting the state information from the target controller.

In this step, the gateway may check each device object in the data synchronization management table, classify the device object according to the device number field and the "timing reading period" value in the code number of the device object, and if the "timing reading period" value is a fixed value (e.g., a preset minimum value or a preset maximum value of the reading period), perform timing reading on the device object according to the time interval defined by the "timing reading period" of the device object, and use the data interface corresponding to the device in the device data interface mapping relationship table to perform timing reading on the device to which the corresponding subsystem belongs.

Before the time of the timed reading period is up, if a data object actively uploaded by the subsystem device is received, the gateway cancels the active reading operation of the data object in the current period.

The gateway can also request the state information from the target controller to actively read when the state information uploaded by the target controller is not received in the timing reading period.

Step 130, if the object monitoring type is the gateway type, judging whether the target equipment object meets the matching condition according to the state information; and if so, generating a control instruction according to the operation information, and sending the control instruction to the output equipment object.

In this step, the object monitoring type may be determined according to the management deployment point location of this linkage, and the management deployment point location may be set by the user as required in the linkage rule configuration table. The management deployment site may be a gateway, and thus the object monitoring type may be a gateway type. The gateway can inquire the matching condition of the synchronous management table, judge whether the read state information is consistent with the matching condition, if the read state information is consistent with the matching condition, generate a control instruction according to the operation information corresponding to the output terminal in the synchronous management table, and send the control instruction to the output equipment object so that the output equipment object can complete the corresponding operation, thereby realizing linkage.

In one embodiment, the output device object includes an output controller, and matching the data records further includes: a push cycle;

before sending the status information to the output device object in step 130, the method further comprises the following steps:

and acquiring real-time grades of the target equipment object in the linkage rule configuration table according to the object information of the target equipment object, wherein the real-time grades comprise a high grade, a medium grade and a low grade.

In the step, the pre-configured linkage rule table contains real-time grade information of the linkage rule corresponding to each target equipment object, the real-time grades comprise a high grade, a medium grade and a low grade, and a user can set different real-time grades for linkage rules with different requirements when the real-time grades are configured.

For the transmission of the status information to the output device object in step 130, the method includes the following steps:

if the real-time level is high, the state information is sent to an output controller in real time;

if the real-time grade is a medium grade or a low grade and a request of an output controller is received in a push period, sending the state information to the output controller according to the request;

and if the real-time level is the middle level or the low level and the request of the output controller is not received in the push period, sending the state information to the output controller according to the push period.

In the process, because the linkage rules in different services have different importance scores, when a user carries out a linkage rule configuration table, the importance of different rules can be defined according to requirements, the rule with high importance degree is defined as the real-time grade of the rule with high importance degree as the high grade, and when the real-time grade is the high grade, the real-time requirement is ensured by correspondingly adapting a mode that the data interaction speed is high in data processing.

If the real-time level is high, the state information is sent to the output controller in real time, and the time required between interactions can be greatly shortened by directly forwarding the state information.

If the real-time level is a medium level or a low level, the importance degree is low, and even if a certain time difference exists in information interaction, the information interaction cannot generate large influence. When the real-time level is a medium level or a low level, the field controller can request the gateway for information according to a specified period. If the gateway receives the request of the output controller in the pushing period, the state information is sent to the output controller according to the request; if the gateway does not receive the request of the output controller in the push period, the gateway can send the state information to the output controller when the push period arrives.

In a specific implementation, the output device object may be determined according to the operation information in the synchronization management table, and when the operation information indicates that the terminal is responding to the operation at the time, the state information is sent to the site controller controlling the terminal to control the terminal to perform the responding operation by the site controller, and the output controller is used for controlling the terminal at the time. When the operation information indicates that the response operation is the field controller, the output controller at the moment is used for controlling the field controller to complete the response operation.

In one embodiment, matching the data records further comprises: the pushing type corresponds to a pushing period, and the pushing period comprises a fixed period and a synchronous period;

aiming at the steps, the method for sending the state information to the output equipment object when the push cycle arrives comprises the following steps:

if the pushing period is a fixed period and the state information is judged to be changed from the state information acquired last time, the state information is sent to the output controller when the fixed period is reached;

and if the pushing period is a synchronous period, sending the state information to the output controller when the synchronous period is reached.

In this process, the fixed period may be a preset push period maximum value (corresponding to Tgtf2[ max ] of fig. 6), a preset push period minimum value (corresponding to Tgtf2[ min ] of fig. 6), or a specified period value between the maximum value and the minimum value range (corresponding to Tgtf2[ min: max ] of fig. 6), and in a specific implementation, since the real-time level is a middle level or a low level, the fixed period may be generally set as the preset push period maximum value in order to reduce resource burden and the like. When the push period is a fixed period, in order to further improve the efficiency of the gateway, in a case of a low level, it may be simultaneously satisfied that when the received state information changes from the state information obtained last time and the fixed period arrives, the state information is sent to the output controller.

When the push cycle type is a synchronous cycle, the gateway forms a synchronous cycle time regulating value according to the self resource load condition and the time range defined by the synchronous cycle, namely between the preset push cycle minimum value and the preset push cycle maximum value range, and when the time of the synchronous cycle is reached, the state information is sent to the output controller.

Step 140, if the object monitoring type is a non-gateway type, the state information is sent to the output device object device, so that the output device object executes the operation corresponding to the operation information when judging that the state information satisfies the matching condition. .

In the step, the non-gateway type can be a field controller type, the field controller can support the mode of sending a linkage rule configuration table to the field controller by the gateway to realize linkage function import and change, can monitor the trigger conditions of each linkage rule in the linkage rule configuration table in real time, and executes corresponding linkage output control operation when the conditions are matched.

If the object monitoring type is the field controller type, the gateway sends the read state information to the output controller, the output controller judges whether the matching condition is met or not according to the state information, and when the matching condition is met, a control instruction can be generated to control a corresponding terminal under the control instruction to execute the operation corresponding to the operation information or control the terminal to execute the operation corresponding to the operation information.

Illustratively, referring to the linkage rule with the linkage rule number of 3 in the linkage rule configuration table of fig. 5, when one of the linkage rules in the linkage rule configuration table is defined as: when the entrance guard exit button P7 of the building point B has an action, the corresponding elevator C of the building area automatically drives by taking the floor where the entrance guard of the point B is located as a target floor, and when the entrance guard of the point B is located in a waiting hall, the beautiful light lamp is turned on. When the entrance guard exit button state code of the building site B is S4N7P7, the entrance guard exit button state value P1 of the site controller S4N7 to which the entrance guard management subsystem S4 belongs is represented; the set value code of a destination floor Fn (such as a floor 8) corresponding to the running of the elevator C in the building area to which the point B belongs is S5N8P6, and the current elevator running destination floor number P6 of the site controller S5N8 to which the elevator control management system S5 belongs is represented; the switch state code of the beautiful light lamp of the floor waiting hall to which the building site location B belongs is S6N5P5, and the beautiful light lamp state P5 of the floor waiting hall to which the site controller S6N5 to which the lighting management subsystem S6 belongs is shown. The object factor S4N7P7 is input, and the linkage trigger condition can be expressed as: (S4N7P7 ═ true), the output object is S5N8P 6: fn, S6N5P 5: and (4) ON.

Further, when the user determines that the real-time level of the rule is a high level and the object monitoring type is a non-gateway type, the gateway receives the state information of the door access exit button P7, and then sends the state information to the corresponding field controller, the controller performs matching judgment on the state information of the P7 and matching conditions of the linkage rule configuration table, and when the door access exit button P7 is monitored to act, the field controller outputs an output object S5N8P 6: fn, S6N5P 5: and ON, generating a control command, controlling the elevator to move to the appointed floor and controlling the beauty lamp to be turned ON.

In one embodiment, the synchronization management table is constructed as follows:

receiving a linkage rule configuration table sent by an application platform layer, wherein the linkage rule configuration table comprises a plurality of linkage rule data records;

and constructing a synchronous management table based on the linkage rule configuration table.

In the process of establishing the synchronous management table, after the user writes the linkage rule configuration table, the linkage rule configuration table can be sent to the gateway through the application platform layer, and after the linkage rule configuration table is received by the gateway, the synchronous management table is established according to the linkage rule content corresponding to each terminal in the table.

In one embodiment, the synchronization management table includes the following fields: the method comprises the following steps of object identification, a real-time associated equipment set, an active push equipment set and an object monitoring type; the object monitoring type comprises a gateway type and a non-gateway type; the linkage rule configuration table records a plurality of linkage rule records, and each linkage rule record comprises: inputting a set of objects, a real-time level of a current rule, and a set of output objects; the real-time level comprises a high level, a middle level and a low level;

aiming at the linkage rule configuration table based synchronization management table in the steps, the method comprises the following steps:

sequentially filling input objects of each input object set in the linkage rule configuration table into object identification fields of the synchronous management table;

reading a real-time grade from the linkage rule record of each input object, and taking an output object set recorded in the linkage rule record where the input object is located as a real-time associated equipment set of the current input object if the real-time grade is high and the corresponding object monitoring type is a non-gateway type;

and if the real-time level is a medium level or a low level, or the real-time level is a high level and the corresponding object monitoring type is a gateway type, taking the output object set recorded in the linkage rule record where the input object is located as an active push equipment set of the current input object.

In the process, the input objects of each input object set in the linkage rule configuration table are sequentially filled in the object identification fields of the synchronous management table, so that the gateway can clearly position each terminal and the corresponding matching data record when inquiring the synchronous management table. For example, referring to the linkage rule number 1 in the linkage rule configuration table of fig. 5, the input objects in the input object set are S1N1P1 and S2N3P6, and corresponding to the first and second pieces in the synchronization management table of fig. 6, the data object numbers are S1N1P1 and S2N3P6, respectively, and these two data object numbers are the input objects in the input object set and are sequentially filled in the object identification field of the synchronization management table, so that the linkage rule that both terminals are used as input objects can be inquired for both S1N1P1 and S2N3P 6.

For each input object in the process, reading the real-time grade from the linkage rule record of the input object, if the real-time grade is high grade and the corresponding object monitoring type is a non-gateway type, the output object set recorded in the linkage rule record where the input object is located is used as the real-time associated equipment set of the current input object, in the step, each linkage rule is preset to be a corresponding real-time grade, when the linkage rule is set to be a high grade in a linkage rule configuration table, a deployment point position is set to be a field controller, that is, the object monitoring type in the corresponding synchronization management table is a non-gateway type, at this time, in the synchronization management table, for the corresponding matching data record under the input object, the real-time association device set is composed of output objects in the output object set recorded in the linkage rule record where the input object is located.

In the step, if the real-time level is the middle level or the low level, or the real-time level is the high level and the corresponding object monitoring type is the gateway type, an output object set recorded in the linkage rule record where the input object is located is used as an active push device set of the current input object.

In one embodiment, the synchronization management table further includes the following fields: an active reading period, an active push type and an active push period;

aiming at the linkage rule configuration table based synchronization management table in the above steps, the method also comprises the following steps:

determining an active reading period and an active pushing type of each input object according to the real-time grade recorded by each input object in the linkage rule record of the input object;

and determining a corresponding active push period according to the active push type.

In the process, the real-time grade recorded by each input object in the linkage rule record determines the active reading period and the active pushing type of the input object. In a specific implementation, in order to ensure the real-time requirement and also ensure the information data interaction efficiency of the gateway and reduce the load of the gateway, when the real-time level is a high level, the active reading period may be set to a preset reading period minimum value (corresponding to Tgrf1[ min ] in fig. 6), when the real-time level is a medium level, the active reading period may be set to a range value between the preset reading period minimum value and a preset reading period maximum value (corresponding to Tgrf1[ min: max ] in fig. 6), and when the real-time level is a low level, the active reading period may be set to a preset reading period maximum value (corresponding to Tgrf1[ max ] in fig. 6).

When the recorded real-time level is a high level, the real-time push can be realized without processing the field of the active push type, and conditions such as period and the like do not need to be set. And when the data belongs to the middle level, adding a 'synchronization period' under the field of the active push type, and if the data belongs to the low-level real-time performance, adding a 'fixed period' under the field of the active push type.

Determining a corresponding active push period according to the active push type, when the field of the active push type is empty, performing real-time push by using a data interface corresponding to each device in a device data interface mapping relation table, when the field of the active push type is a synchronization period, setting the active push period to be a range value between a preset push period minimum value and a preset push period maximum value, and when the field of the active push type is a fixed period, setting the active push period to be the preset push period maximum value.

In one embodiment, the synchronization management table further includes the following fields: object combination matching conditions and a notification device set; the linkage rule record further includes: a linkage trigger condition;

and if the real-time level of the current input object is a medium level or a low level, inputting the linkage trigger condition recorded by the current input object in the linkage rule configuration table to the object combination matching condition field of the synchronous management table, and taking the output object set recorded in the linkage rule record of the input object as the notification equipment set of the current input object.

In this step, when the level is low or medium, the corresponding linkage rule configuration table inputs the linkage trigger condition to the object combination matching condition field of the synchronous management table, the corresponding output object set is used as the notification device set of the current input object, after the gateway acquires the state information, the gateway can judge whether the condition that the linkage device needs to respond is met according to the object combination matching condition in the synchronous management table, and when the information state of the input object meets the corresponding object combination matching condition, the gateway generates the control instruction according to the output object recorded in the notification device set and the operation that the output object should respond.

When the real-time level is a high level, the gateway can directly send the state information to the controller corresponding to the output object in the set according to the real-time associated equipment set after acquiring the state information, and the controller judges the matching condition according to the linkage rule configuration table. Therefore, when the real-time level is a high level, in the synchronization management table, the object combination matching condition field and the notification device set may be empty sets, and when facing the empty sets of the two parts in the synchronization management table, it may indicate that the gateway does not need to determine the matching condition, and only needs to complete data forwarding.

In this embodiment, the building gateway may automatically generate the "full system associated object definition table" and the "synchronous management table" according to the service layer linkage rule, thereby implementing dynamic construction or adjustment of a bottom layer synchronous mode mechanism for data interaction of each subsystem adapted to the building gateway according to the service layer linkage requirement, and greatly improving the universality and expandability of multi-service linkage management deployment in a large-scale building integrated management application scenario.

In addition, through a mixed linkage management deployment mode of gateway centralized type or field controller distributed type, data objects belonging to each subsystem can be docked in any form such as active/passive acquisition, and the flexibility and adaptability of the system linkage deployment and docking mode are ensured particularly under the conditions that the types of the current building subsystems are various, and the service control functions and data interface modes of different subsystems are different.

In one embodiment, the method further comprises the following steps:

when the linkage rule configuration table is detected to be updated, acquiring the updated content;

and updating the synchronous management table according to the updated content.

In the process, the gateway can judge whether the linkage rule configuration table needs to be detected or not by checking whether a newly uploaded linkage rule configuration table exists or whether a user modifies the original linkage rule configuration table or not, if the detection result shows that the existing linkage rule configuration table is not completely consistent with the linkage rule configuration table in the last detection, the gateway can rebuild the synchronous management table according to the content of the existing linkage rule configuration table, can also screen out inconsistent contents in the two linkage rule configuration tables, and correspondingly updates the content of the synchronous management table according to the inconsistent contents.

In addition, when the field controller belongs to the first access gateway or the connection state with the gateway changes or the linkage trigger condition changes, the gateway sends the latest linkage trigger condition to the corresponding field controller.

In one embodiment, the method further comprises the following steps:

acquiring the resource load rate of the gateway;

adjusting the synchronization period by adopting the resource load rate, wherein the adjustment comprises the following steps: when the resource load rate does not exceed the preset minimum value, setting the synchronization period as the preset pushing period minimum value; when the resource load rate is in an ascending state compared with the previously acquired resource load rate, the synchronization period is increased by a specified increase amplitude; and when the resource load rate exceeds the preset maximum value, adjusting the synchronization period to the preset pushing period maximum value.

In the process, the gateway can dynamically adjust the synchronization period within a range from a preset pushing period minimum value to a preset pushing period maximum value defined by the active pushing period according to the current resource load condition, and when the resource load rate does not exceed the preset minimum value, the synchronization period can be set as the preset pushing period minimum value. When the resource load rate is increasing but does not reach the upper limit, the allowance of the current resource of the gateway is still larger, and the setting time of the synchronization period can be gradually reduced. In specific implementation, when the resource load rate reaches 80%, the synchronization period may be adjusted to a preset maximum value of the push period, so as to relieve the load pressure of the gateway.

In a specific implementation, referring to a data synchronization mode adaptive adjustment scheduling diagram based on gateway resource load sensing in fig. 7, when a push type is a fixed period, the fixed period is set to a preset push period maximum value, and when read state information changes with content of the previous time, a control instruction is sent to a corresponding controller through steps of determining an output device object, querying a corresponding interface relationship, and the like; when the resource load rate does not exceed the preset minimum value, setting the synchronization period as the preset pushing period minimum value; when the resource load rate does not reach a preset upper limit value, reducing according to a certain calculation mode, if a preset pushing period minimum value n is a reduction amplitude, n is a preset numerical value, exemplary n can be 0.2, subtracting the reduced numerical value from a current synchronization period value to obtain a difference value as a latest synchronization period, comparing the latest synchronization period with the preset pushing period minimum value, if the value is greater than or equal to the preset pushing period minimum value at the moment, setting the synchronization period as the latest synchronization period value, and if the value is less than the preset pushing period minimum value, setting the synchronization period as the preset pushing period minimum value; and when the resource load rate reaches a preset upper limit value, setting the synchronization period as a preset pushing period maximum value.

In this embodiment, the gateway can adaptively adjust the data synchronization mode through the gateway's own resource load sensing according to different real-time level requirements in the service layer linkage rules, thereby ensuring the linkage service real-time.

In specific implementation, referring to the schematic diagram of the early warning process of the gateway resource load rate and the system scale matching in fig. 8, the gateway may continuously detect the resource load rate of the gateway, determine that the scale of the subsystem or the number of controller nodes to which the gateway is connected exceeds the upper limit when both the active reading period and the synchronization period reach the maximum value and the gateway resource load rate still exceeds the preset maximum value, and immediately send out an alarm message, at this time, a system administrator should generally adjust or optimize the number of the subsystem devices to ensure the real-time performance of the linkage application.
