Detailed Description

The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

It should be noted that: in the present examples, "first", "second", etc. are used for distinguishing similar objects and are not necessarily used for describing a particular order or sequence.

The technical means described in the embodiments of the present application may be arbitrarily combined without conflict.

Fig. 1 is a schematic view of an internet of things system provided in an embodiment of the present application, and as shown in fig. 1, the internet of things system includes

resource devices

11, 12, 13, 14, and 15, and a server 16. Wherein:

the

resource devices

11, 12, 13, 14 and 15 may be sensor nodes in the internet of things. The sensor node comprises a sensor and a communication module, wherein the sensor is used for sensing data, and the communication module is used for communication of the resource device. When the system is implemented, the resource devices can be an intelligent sound box, an air conditioner, an electric lamp, a kettle, a television, a mobile phone, a computer, an intelligent watch, an augmented reality device or a virtual reality device and the like.

The server16 may be an internet of things connection management platform, an internet of things application server or gateway, and the like.

In the implementation process, the resource devices 11 to 15 may all be connected to the server16, the server16 may perform information interaction with the resource devices 11 to 15, for example, the server16 may manage the resource devices 11 to 15, such as at least one of resource device software and hardware upgrade, resource device function control, resource subscription, and resource query. It should be understood that in other embodiments, the resource device14 or 15 may be directly connected to the server 16.

The resource devices may also be connected to each other, for example, the resource device11 may be connected to the

resource devices

14 and 15, respectively, messages or data between the server16 and the resource device14 are forwarded via the resource device11, and the resource device11 may also perform certain processing on the forwarded messages or data, such as data preprocessing/filtering, communication protocol or message format conversion, and the like.

The resource devices or the resource devices and the server are in communication connection through the communication module.

It should be noted that, in the embodiments of the present application, a connection manner or a communication protocol between resource devices, or between a server and a resource device is not limited. For example, the server16 and the resource devices 11/12/13, or the

resource devices

11 and 14/15 may use a wired connection and use a restricted Application Protocol (CoAP) for data or Message transmission, or the server16 and the resource devices 11/12/13, or the

resource devices

11 and 14/15 may use a cellular narrowband Internet of Things (NB-IoT) wireless connection technology and use a Message Queuing Telemetry Transport (MQTT) Protocol for data or Message transmission.

It should be noted that, in the internet of things technology, a server manages resource devices in a resource form, where "resource" is an abstract concept, and may refer to a physical resource device, a model, a software/hardware version, or a manufacturer of the resource device, or a dynamic attribute such as an operation that can be executed by the resource device, a reported event, a parameter, or a readable state parameter. Each Resource has a unique Identifier, which may be a name, a Uniform Resource Identifier (URI), a Uniform Resource Locator (URL), or any other type or format that can distinguish and identify the Resource. In this application, URI is taken as an example to identify a resource, for example, URI of server16 is "/server16", URI of resource devices 11 to 15 are "/server16/device11", "/server16/device12", "/server16/device13", "/server16/device11/device14", "/server16/device11/device15", respectively.

Fig. 2 is a schematic diagram of an information processing process of a server in the internet of things according to an embodiment of the present application, and as shown in fig. 2, the server has a rule resource (oil.r.rule), where the rule resource is an aggregate resource, and the aggregate resource includes a rule input resource (oil.r.rule) 21, a rule expression resource (oil.r.rule expression) 22, and a rule behavior resource (oil.r.rule action) 23.

The Rule Input resource 21 and the Rule behavior resource 23 are both a Collection resource, and may include a Rule Input Collection (Rule Input Collection) and a Rule behavior Collection (Rule Actions Collection), respectively. For a rule, the rule inputs of the rule are stored in the rule input resource 21, and the expression of each rule input is as follows:

{ "anchor" - "mytemperature" -// alias of rule input, used in ruleexpress;

"href"/mylocalteparaturesensor "// relative URI of hardware for rule input

"rel" [ "ruleinput" ],// meaning is a regular input

"rt" [ "oic. R. Temperature" ],// resource type

If [ "oic. If. S" ]// interface }

The regular expression resource 22 includes regular expressions and rule results, for example, a regular expression may be: temperature > = "25", when the rule result is changed from false to true, that is, the rule input is changed from not satisfying the rule expression to satisfying the rule expression, the rule action is executed, and the execution of the rule action generally modifies the attribute of a certain resource or a series of resources.

Continuing with fig. 2, when the Rule input resource 21 of the server receives a resource (e.g., mytemperature), which may be a resource on the server or a resource of a resource device outside the server, the server may link to the Rule input (e.g., a value of mytemperature) according to the received resource, that is, the server obtains the Rule input according to the resource, the Rule input may be understood as a value of the resource, the server may transmit the Rule input to the Rule expression, if the Rule Enable (Rule Enable) is true, the server determines whether the Rule input satisfies the Rule expression, if so, outputs a Rule result, if the Rule result is true and the behavior Enable (Action Enable) is true, links scene information in the scene set according to the Rule result, and assigns the scene information linked to the scene set to the scene information in the Rule behavior resource 23. The rule input is an input element of the rule determination condition, the rule expression is an expression formed from the respective rule inputs, and the rule behavior is executed if the rule expression is determined to be true.

The rule enable is used for enabling the server not to judge the rule expression, for example, the server may control to disable/enable a resource for a period of time, so that the rule enable corresponding to the resource is false/true. The behavior enable is used to determine whether to execute the behavior action when the rule result is true, and the true or false of the rule enable and the behavior enable can be determined based on the operation of the user or the configuration determination.

Introducing an internet of things scene, wherein the rule in the server is that the air conditioner is turned on when the indoor temperature reaches 30 ℃, the temperature is input as a rule, the temperature is greater than or equal to 30 and is a rule expression, when the temperature changes, a rule engine of the server judges whether the temperature is greater than or equal to 30, and if the judgment result is true, the rule behavior of turning on the air conditioner is executed.

In the current technical architecture of the internet of things, a server running a rule needs to subscribe to a resource pointed to or linked (link) by a rule input (ruleInput) resource, which may be referred to as a target input resource, for example, a temperature sensor of a resource device. When the attribute information of the target input resource changes, the resource equipment sends a notification message to the server running the rule, and after receiving the notification message, the server substitutes the attribute value of the attribute information of the target input resource into the rule expression for calculation. However, each time the notification message of the target input resource causes the server to perform the calculation of the regular expression, the resource of the server is greatly wasted.

Based on at least the existing problems, fig. 3 is a schematic view of an implementation flow of a transmission method for messages in the internet of things according to an embodiment of the present application, as shown in fig. 3, the method is applied to a server, and the method includes:

s301, the server sends a first request to the first device, wherein the first request indicates that the first device sends a notification message to the server under the condition that the attribute information of the first resource meets the trigger condition, and the notification message includes or indicates the attribute information of the first resource.

The first device may be any of the resource devices listed above.

The first device in the embodiment of the present application may be understood as an input resource device (inputDevice), and the server in the embodiment of the present application may be understood as a rule resource device (ruleDevice).

There is a resource referenced by the rule input (ruleInput) on the inputDevice, that is, a certain resource of the inputDevice is used as an input resource for the rule.

A ruleDevice is a resource device that stores a ruleInput resource, a rule expression ruleExpression resource, and a rule behavior ruleAction resource, and runs the entire rule on the ruleDevice.

The first resource may be a resource in the first device, e.g., a sensor in the first device; alternatively, the first resource may be a resource outside the first device, for example, a camera in the first device captures an image of a certain target/object, and the first resource is a resource in the target/object.

The attribute information of the first resource may be obtained by: the first device senses attribute information of the first resource, or one device outside the first device senses the attribute information of the first resource and sends the attribute information of the first resource to the first device.

In one embodiment, the trigger condition of the notification message may be included in the first request, so that the first device may obtain the trigger condition by parsing the first request.

In another embodiment, the first request may not include the trigger condition of the notification message, but may include at least one of an identifier, an address, an index, or a link of the trigger condition, so that the first device may acquire the trigger condition based on the at least one of the identifier, the address, the index, or the link of the trigger condition.

In this embodiment, the trigger condition is determined by the server, at least one resource may be located on one resource device, and different resources on one resource device may correspond to different trigger conditions, for example, one resource device may correspond to a trigger condition of a temperature resource and a trigger condition of a brightness resource.

In one embodiment, the notification message indicates attribute information of a first resource of the first device. For example, the notification message includes a resource identifier (e.g., a URI or a resource name) of the first resource, so that the server can obtain the attribute information of the first resource through the resource identifier of the first resource.

In another embodiment, the notification message may include attribute information of the first resource, so that the server may parse the notification message to obtain the attribute information of the first resource.

The attribute information of the first resource may include an attribute value of the first resource. In one embodiment, the attribute information of the first resource may further include at least one of status information, data category, location information, and parameter information of the first device. In an implementation, the property value of the first resource may be a value measured by a sensor, for example, a sensing value of a sensor. It should be appreciated that in one possible implementation, the first device may also include a second resource, a third resource, etc., each of which may have its own attribute information.

To the extent that the resource of the first device is a sensor (e.g., a sensor) in the first device, the first device can be, for example, a monitoring resource device for monitoring the opening or closing of a door of a room, and the first resource can be a sensor in the monitoring resource device. In one implementation scenario, when the room door is opened, the sensing value of the sensor is 1, and the attribute value of the first resource is 1, where 1 indicates that the room door is opened; when the room door is closed, the sensing value of the sensor is 0, and the attribute value of the first resource is 0, where 0 indicates that the room door is closed.

S303, the server receives the notification message sent by the first device.

It should be understood that, when the notification message includes the resource identifier of the first resource of the first device, the server obtains the resource identifier of the first resource by parsing the notification message, and obtains the attribute information of the first resource corresponding to the resource identifier.

When the notification message includes the attribute information of the first resource of the first device, the server obtains the attribute information of the first resource of the first device by analyzing the notification message.

In the embodiment of the application, the server sends the first request to the first device, so that the server can receive the notification message sent by the first device only when the attribute information of the first resource meets the trigger condition, instead of receiving the notification message sent by the first device as long as the attribute information of the first resource changes, the number of the notification messages received by the server is reduced, and the computing resources of the server are reduced.

Fig. 4 is a schematic view of an implementation flow of another method for transmitting a message in the internet of things according to the embodiment of the present application, and as shown in fig. 4, the method includes:

s401, a server sends a first request to a first device, wherein the first request indicates that the first device sends a notification message to the server under the condition that attribute information of a first resource meets a trigger condition, and the notification message comprises or indicates the attribute information of the first resource; the first device receives a first request sent by a server.

When the first request includes the trigger condition, the first device may obtain the trigger condition by parsing the first request. When the first request indicates the trigger condition, the first device may obtain an identifier, an address, an index, or a link of the trigger condition by parsing the first request, and obtain the trigger condition from a server or other devices based on the identifier, the address, the index, or the link of the trigger condition.

S403, the first device monitors the attribute information of the first resource, and determines that the attribute information of the first resource meets the trigger condition.

The first device may monitor the attribute information of the first resource continuously or periodically or aperiodically, determine whether the attribute information of the first resource satisfies a trigger condition each time the attribute information of the first resource is monitored, send a notification message to the server if the first device determines that the attribute information of the first resource satisfies the trigger condition, not send the notification message to the server if the first device determines that the attribute information of the first resource does not satisfy the trigger condition, and the first device continues to monitor the attribute information of the first resource.

S405, the first equipment sends a notification message to a server; the server receives the notification message sent by the first device.

In the embodiment of the application, when the first device interacts with the server, because the first device can acquire the trigger condition through the first request sent by the server, the first device sends the notification message to the server only when monitoring that the attribute information of the first resource meets the trigger condition, and further the number of the notification messages received by the server is small, and the calculation resources of the server are low.

Fig. 5 is a schematic view of an implementation flow of another method for transmitting a message in the internet of things according to the embodiment of the present application, and as shown in fig. 5, the method includes:

s501, the server creates rule resources.

The rule resources may include constraints (the constraints in the embodiment of the present application may be both understood as first constraints), N input resources corresponding to the constraints, and M behavior resources corresponding to the constraints; n is a positive integer greater than or equal to 1; m is a positive integer greater than or equal to 1. Wherein the N input resources include a first resource. Constraints can be understood as regular expressions.

In one case, any one of the N input resources is different from any one of the M behavior resources. In another case, a portion of the N input resources are the same as a portion of the M behavior resources.

In one embodiment, the rule resources created by the server may include at least two constraints, input resources corresponding to the at least two constraints, and behavior resources corresponding to the at least two constraints. Wherein the at least two constraints may include a first constraint.

For example, the rule resources created by the server may include a first constraint and a second constraint, and N input resources corresponding to the first constraint, M behavior resources corresponding to the first constraint, P input resources corresponding to the second constraint, and Q behavior resources corresponding to the second constraint. Wherein P or Q is a positive integer greater than or equal to 1. Wherein, any input resource in the N input resources is different from any input resource in the P input resources, or part of the N input resources is the same as part of the P input resources. Any behavior resource in the M behavior resources is different from any behavior resource in the Q behavior resources, or a part of behavior resources in the M behavior resources is the same as a part of behavior resources in the Q behavior resources.

Referring to fig. 2, the rule resources include a rule input resource, a rule expression resource, and a rule behavior resource. Wherein the at least two constraints may be included in the regular expression resources, the input resources corresponding to the at least two constraints may be included in the regular input resources, and the behavior resources corresponding to the at least two constraints may be included in the regular behavior resources.

It should be noted that, in the embodiment of the present application, the rule resource includes the first constraint condition as an example, and a transmission manner of the message is described, and it should be understood by those skilled in the art that, when the rule resource includes at least two constraint conditions, the transmission manner of the message is similar to that when the rule resource includes the first constraint condition.

The number of N in the embodiment of the present application may be the same as the number of resources in the constraint condition. For example, when the constraint is "(resource a > 17) and ((resource B = false) or (resource C < 16))", there are three resources A, B and C in the constraint, and the resources corresponding to the constraint are resources A, B and C.

In the embodiment of the present application, a certain input resource of the N input resources and a certain behavior resource of the M behavior resources may be resources on the same device, or may be resources on different devices.

In one embodiment, the server may determine the constraints based on user input. For example, the server may receive user input "(resource a > 17) and ((resource B = false) or (resource C < 16))", resulting in a constraint "(resource a > 17) and ((resource B = false) or (resource C < 16))".

In another embodiment, the server may modify the constraints based on the user's manipulation of the constraints. For example, the server may receive an operation that the user modifies "resource C <16" to "resource C < 25", thereby modifying the constraint condition to "(resource a > 17) and ((resource B = false) or (resource C < 25))".

In yet another embodiment, the determination and modification of the constraints may be by configuration. For example, the server may receive configuration information sent by one resource device, and the configuration information may include or indicate a constraint condition, or include or indicate modification information for the constraint condition, so that the server may obtain the constraint condition based on the configuration information, or may modify the constraint condition based on the configuration information.

S503, the server sends a request for subscribing the first resource to the first device; the first device receives a request sent by a server to subscribe to a first resource.

In the scenario of the internet of things, after obtaining the created rule resource, the server needs to register a resource in the rule resource, and generally, the server may send a resource subscription request to one or at least two devices corresponding to the resource in the rule resource, where the resource subscription request may include or indicate a resource identifier to be subscribed.

For example, the server may send the identifier or name of the first resource to the first device, so that the first device may subscribe to the first resource based on the received identifier or name of the first resource. That is, the identity or name of the first resource may be included in the request to subscribe to the first resource.

It can be understood that the server may subscribe to not only the first resource of the first device, but also to other resources in the first device, such as the second resource, the third resource, etc. in the first device, or may subscribe to resources in other resource devices in the internet of things.

The first device may store the identifier or name of the first resource in a subscription resource of the first device, and after the storage is completed, the first device completes the subscription of the first resource.

S505, the first device sends a first message to the server, wherein the first message includes or indicates that the first resource subscription is successful.

After the first device becomes a subscription for the resource, the first device may send a first message to the server. The first message can also be understood as a resource subscription success message; the server receives a first message sent by the first device.

After the server receives the first message sent by the first device, the server determines that the first resource subscription is completed.

In implementation, the server may determine the trigger condition based on the constraint condition.

In one embodiment, if N is equal to 1, that is, only one rule input resource is in the rule resources created by the server, the server may determine the trigger condition based on an expression corresponding to the one rule input resource (first resource) included in the constraint condition. For example, the server may determine the constraint as a trigger. As another example, the server may modify parameters in the constraints to obtain the trigger conditions.

In another embodiment, if N is greater than 1, that is, under the condition that the rule resource created by the server includes at least two rule input resources, the server may decompose the constraint condition, so that the trigger condition may be obtained based on the expressions respectively corresponding to the at least two decomposed rule input resources, where the implementation process of determining the trigger condition based on the constraint condition by the server may refer to S507 to S509.

S507, the server decomposes the constraint condition into N sub-conditions; the N sub-conditions correspond to the N input resources one by one; and determining the sub-condition corresponding to the first resource from the N sub-conditions.

One of the sub-conditions corresponds to one resource, that is, when the constraint condition is decomposed into N sub-conditions, one sub-condition corresponds to only one resource. For example, when the constraint is "(resource a > 17) and ((resource B = false) or (resource C < 16))", the server can resolve the constraint into three sub-conditions, "resource a >17" corresponding to resource a, "resource B = false" corresponding to resource B, and "resource C < 25" corresponding to resource C, because the constraint has three resources, respectively, resource a, resource B, and resource C.

Since the N sub-conditions include the sub-condition corresponding to the first resource, the server may determine the sub-condition corresponding to the first resource from the N sub-conditions.

S509, the server determines a trigger condition based on the sub-condition corresponding to the first resource.

Wherein the trigger condition may include one of: the attribute information of the first resource is greater than a first threshold; in a first time period, the attribute information of the first resource is larger than a first threshold value; the attribute information of the first resource is smaller than a second threshold; within a second duration, the attribute information of the first resource is smaller than a second threshold; the attribute information of the first resource changes within the third duration, and the changed value is greater than the first value.

The first duration, the second duration, and the third duration may be durations determined by the first device itself, or the first duration, the second duration, and the third duration may be durations configured by the server or other devices. The first duration, the second duration, or the third duration may be an operation duration of a certain timer before timeout.

In one embodiment, the server may determine a sub-condition corresponding to the first resource as the trigger condition. For example, the sub-condition corresponding to the first resource is "resource a >17", and the determination trigger condition is also "resource a >17".

In another embodiment, the server may modify the determined sub-condition corresponding to the first resource, and determine the modified sub-condition corresponding to the first resource as the trigger condition. That is, the threshold or the value corresponding to the sub-condition corresponding to the first resource may be greater than or less than the threshold or the value corresponding to the trigger condition. In an embodiment, the server may determine a threshold or a value corresponding to a sub-condition corresponding to the first resource, and add or subtract a certain value to or from the threshold or the value corresponding to the sub-condition to obtain the threshold or the value corresponding to the trigger condition. For example, when the sub-condition corresponding to the first resource is "resource a >17", the trigger condition may be "resource a >18", or the trigger condition may be "resource a >15".

It should be noted that, in the embodiment of the present application, the steps S503 to S505 and the step server determine the trigger condition based on the constraint condition, and the execution sequence of the steps is not limited, for example, the steps S503 to S505 may be executed first, and then the step server determines the trigger condition based on the constraint condition, or the step server determines the trigger condition based on the constraint condition first, and then the steps S503 to S505 are executed, or the steps S503 to S505 and the step server determine the trigger condition based on the constraint condition, and may be executed synchronously.

S511, the server sends a first request to the first device, wherein the first request indicates that the first device sends a notification message to the server under the condition that the attribute information of the first resource meets the trigger condition, and the notification message comprises or indicates the attribute information of the first resource; the first device receives a first request sent by a server.

The attribute information of the first resource satisfies the trigger condition, and may include one of:

the attribute information of the first resource is greater than a first threshold;

in a first time period, the attribute information of the first resource is larger than a first threshold value;

the attribute information of the first resource is smaller than a second threshold;

within a second time length, the attribute information of the first resource is smaller than a second threshold value;

the attribute information of the first resource is changed in the third duration, and the changed value is larger than the first value.

S513, the first equipment sends a second message to the server, wherein the second message comprises or indicates that the first equipment completes the setting of the trigger condition; and the server receives a second message sent by the first equipment.

After the first device receives the first request, the trigger condition of the notification message may be obtained based on the first request, and the trigger condition may be set, for example, one implementation of setting the trigger condition may be to store the trigger condition in the first device or in a subscription resource of the first device. After the first device completes setting the trigger condition, a second message may be sent to the server.

S515, the first device monitors the attribute information of the first resource and determines that the attribute information of the first resource meets the trigger condition.

Wherein the notification message comprises or indicates attribute information of the first resource.

It is to be noted that, in the embodiment of the present application, the attribute information of the first resource satisfies the trigger condition, and it can be understood that the attribute value of the first resource satisfies the trigger condition.

S517, the first device sends a notification message to the server; the server receives the notification message sent by the first device.

The first device may send a notification message to the server if it is determined that the attribute information to the first resource satisfies the trigger condition. In one embodiment, the first device may determine that: and if the attribute information of the first resource is larger than the first threshold value, sending a notification message to the server. For example, the triggering condition is that the attribute information is greater than 25, the first device determines that the attribute information to the first resource is 26, and sends a notification message to the server.

In another embodiment, the first device may determine that: and if the attribute information is larger than the first threshold value in the first time period, sending a notification message to the server.

In an implementation, the first device may start and operate a first timer when it is determined that the attribute information of the first resource is greater than a first threshold, where the first timer is configured to run for a first time period and then time out, and during the operation of the first timer, the first device may continuously monitor whether the attribute information of the first resource is still greater than the first threshold, if so, the first device sends a notification message to the server, and if not, the first device does not send the notification message to the server and continues to monitor the attribute information of the first resource.

In yet another embodiment, the first device may determine that: the attribute information of the first resource is less than the second threshold, and a notification message is sent to the server, or the first device may determine that: within the second duration, the attribute information of the first resource is less than a second threshold.

In yet another embodiment, the first device may determine that: and the attribute information of the first resource is changed in the third time length, and the changed value is greater than the first value, and a notification message is sent to the server.

In implementation, the first device may determine, every third duration, the attribute information of the first resource before and after the third duration, and send a notification message to the server if it is determined that a change value of the attribute information of the first resource is greater than the first value. For example, the first device may control a second timer to periodically restart, the second timer is configured to run for a third duration and then time out, and restart the second timer when the second timer times out, and the first device may obtain: and obtaining the change value of the attribute information of the first resource in the first duration by the attribute information of the first resource corresponding to the second timer at the restarting moment and the attribute information of the first resource corresponding to the second timer at the overtime moment.

And S519, the server executes the rule behaviors.

In an embodiment, since the first device has already determined that the attribute information of the first resource satisfies the trigger condition, the server does not need to determine whether the attribute information of the first resource further satisfies the sub-condition corresponding to the first resource, but directly defaults that the attribute information of the first resource already satisfies the sub-condition corresponding to the first resource.

In another embodiment, after obtaining the notification message, the server may obtain the attribute information of the first resource through the notification message, and determine whether the attribute information of the first resource meets the sub-condition corresponding to the first resource.

And if the N is equal to 1, namely only the sub-condition corresponding to the first resource exists in the constraint condition, and the server executes the rule action under the condition that the attribute information of the first resource is determined to meet the constraint condition.

If N is larger than 1, namely at least a sub-condition is included in the constraint condition, and the server determines that the attribute information of the first resource meets the sub-condition corresponding to the first resource, the server acquires the attribute information of N-1 resources except the first resource in the N input resources, and executes the rule behavior when determining that the attribute information of each resource in the N-1 resources meets the sub-condition corresponding to each resource.

In an implementation manner, the server can obtain the attribute information of the N-1 resources through the identifiers of the N-1 resources, and further judge whether the attribute information of each resource in the attribute information of the N-1 resources meets the sub-condition corresponding to each resource.

In another embodiment, the server may determine whether the notification message sent by the device corresponding to the N-1 resources is received, and if so, determine that the attribute information of each resource in the attribute information of the N-1 resources satisfies the sub-condition corresponding to each resource.

It can be understood that, when the constraint condition includes N sub-conditions, if the server determines that any input resource of the N input resources does not satisfy the sub-condition corresponding to the resource, the server does not execute the rule behavior.

The server execution rule behavior may be implemented by: and modifying the attribute information of the M behavior resources.

For example, if the server creates a rule that is: if the door is opened, the light is turned on. Then, a sensor of the monitoring device for detecting the opening and closing of the door, in a case where it is monitored that the door is turned from closed to open, the monitoring device sends an indication of the door to the server, the server determines that the door is turned from closed to open based on the indication of the door, and the server performs a regular action, for example, the attribute information of the resource for turning on or off the lamp may be modified from 0 to 1, where 0 indicates that the state of the lamp is off, and 1 indicates that the state of the lamp is on.

After the server modifies the attribute information of the M behavior resources, the server may send an indication message to a series of resource devices corresponding to the M behavior resources, where the indication message includes or indicates the attribute information of the behavior resources, so that the series of devices can convert the behavior resources to corresponding states based on the attribute information of the behavior resources after obtaining the attribute information of the behavior resources. The series of resource devices includes at least one resource device, which may or may not include the first device.

Referring to fig. 2, when the rule result in the rule expression resource is true, the server may link to the scene information corresponding to the rule result or the rule expression in the scene set based on the rule result, and assign the linked scene information to the scene information of the rule behavior. The scenario information of the rule behavior may be attribute information of a behavior resource in the embodiment of the present application.

In the embodiment of the application, the pressure for judging the sub-condition corresponding to the first resource by the server is sunk and decomposed to each resource device in the manner that the triggering condition is set by the first device, so that the judging times of the server can be effectively reduced, the working pressure of the server is reduced, the resource of the server is saved, and the regular behavior is executed after the server receives the notification message, so that the linkage of the resource devices in the internet of things can be realized.

In another embodiment, after the cloud platform sends the first request to the first device, the first device may default to setting the trigger condition, so that the second message may be sent to the server. The cloud platform can also send a second message to the server after sending the first request and after a certain time interval.

S705, the first device monitors the attribute information of the first resource and determines that the attribute information of the first resource meets the triggering condition.

In another implementation, after the cloud platform receives the third message, the cloud platform may parse the third message to directly obtain the N input resources and the constraint condition.

S811, the cloud platform determines a trigger condition based on the sub-condition corresponding to the first resource.

When the subsets are divided, the subsets may be divided according to resources such that each subset represents only one resource. When ruleDevice decomposes rulExpression, it can decompose according to the number of inputResources. For example, the number of InputResources is N, and the ruleDevice is decomposed into N subsets, where N is a positive integer greater than or equal to 1.

The subsets may be divided according to logical operators such that only one relationship operator may be included in each subset, and the relationship operators may include (">", "> =", "=", "<" = ", and" | = ", etc.). In this way, the attribute value of the subscribed resource meets the relational expression corresponding to the resource after being changed, and then the subscription notification message is sent.

The content of the request for subscribing to the notification condition may be as follows:

to is the address of the resource To which A belongs

CN:{

Oic.r.value.conditional(

Valuecondition：“>17”；)

}

Wherein, the value in the valueCondition is the attribute value of the resource. In addition, each resource binds an oil.r.value.conditional resource that is used to limit the conditions under which the target resource sends the subscription notification message.

The condition of subscribing to the notification message or the subscription notification condition may be a trigger condition in this embodiment of the application.

S851, the inputDevice may send a message that the setting of the notification condition is completed to the ruleDevice after the notification condition is set.

S853, when the subscribed resource information changes, the inputDevice first determines the content of the oic.r.value.conditional resource; if the condition set in the oil.r.value.condition (i.e., the condition of value condition) is satisfied after the value of the subscription resource is changed, S855 is performed, and if the condition set in the oil.r.value.condition is not satisfied after the value of the subscription resource is changed, the subscription notification message is not transmitted. Here, the resource information may be attribute information of the first resource in the embodiment of the present application.

S867, the rule device sends the newly created rule' S rule input resource and rule expression resource to the Cloud platform Cloud, and the rule input resource and the rule expression resource are used for requesting the Cloud platform to send the notification message sending condition of the subscription resource according to the information.

In the implementation process, the server may first perform the step of subscribing the inputDevice, and then perform the step of sending the ruleInput resource and the rulexexpression resource; or, the server may execute the ruleInput resource and the rulexexpression resource first, and then execute the step of subscribing the inputDevice; alternatively, the steps of the server subscribing to the inputDevice and sending the ruleInput resource and the rulexexpression resource may be performed synchronously.

S869, decomposing the rulExpression by the cloud platform; the ruleExpression is decomposed into different subsets (or expressions) according to the resources specified in ruleInput. The cloud platform can set subscription notification conditions of corresponding resources to different inputdevices respectively according to the decomposed expressions.

When subsets are divided, they may be divided according to resources such that each subset represents only one resource. When the subsets are divided, the subsets can be divided according to logical operators, so that each subset only contains one relational operator.

And S871, the cloud platform sends a request of subscribing notification conditions of the subscribed resources to each corresponding inputDevice according to each decomposed subset. The requested content may be the same as the content sent by the ruleDevice to the inputDevice in the above embodiment.

S875, the cloud platform may send a message that the setting notification condition is completed to the ruleDevice. The subscription notification condition of the resource may be a trigger condition in this embodiment of the application.

And after all the request messages are completed and the response messages are received, the cloud platform informs the ruleDevice that the task of setting the informing condition of the subscription resource is completed.

S877, when the attribute information of the subscribed first resource changes, the inputDevice firstly judges the content of the oic.r.value.conditional resource; if the condition set in the oil.r.value.condition (i.e., the condition of value condition) is satisfied after the value of the subscription resource is changed, S879 is performed. The subscription notification message is not transmitted if the condition set in the oil.r.value.condition is not satisfied after the value of the subscription resource is changed.
