fig. 2 is a flowchart of a gateway control method applied to a gateway according to an embodiment of the present invention.
Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
As shown in fig. 1, the architecture of the gateway control method according to an embodiment of the present invention includes a terminal 10, a server 20 and a gateway 30, and it should be understood that the type of the terminal 10 is not limited herein, and may be a computer, a mobile phone, etc. Specifically, it may be that the terminal 10 accepts a user operation of a user, the terminal 10 generates a corresponding operation instruction and transmits the operation instruction to the server 20 to generate policy configuration information at the server 20, the server 20 transmits the policy configuration information to the gateway 30, and then the gateway 30 is capable of implementing a gateway control operation based on the received policy configuration information. Therefore, the intelligent gateway has more flexible functions, can implement rich gateway control strategies according to the strategy configuration information set in different scenes, and supports the gateway to meet the personalized user requirements.
As shown in fig. 2, a flowchart of a gateway control method applied to a gateway according to an embodiment of the present invention includes:
s21, obtaining strategy configuration information, wherein the strategy configuration information comprises strategy decision, strategy condition and strategy action information.
The policy configuration information may be obtained by, for example, directly interacting with a user or interacting with a terminal. Specifically, it may be a user interface through a specific application (e.g. APP) of the user operation terminal, so as to generate an operation instruction at the user terminal, and send the operation instruction to the server to be identified so as to generate corresponding policy configuration information.
And S22, acquiring the equipment information of the equipment linked with the gateway.
As an example, the gateway may be connected to a plurality of networked devices that may upload device information to the gateway in coordinated communication with the gateway.
And S23, judging whether the equipment information meets the strategy condition.
And S24, when the equipment information meets the strategy condition, judging whether the linked equipment needs to be triggered to execute the action indicated by the strategy action information or not based on the strategy decision.
In this embodiment, when the policy application is triggered without the policy condition, the policy application program is in a dormant state and does not occupy any bandwidth of the bus; and the equipment data is directly processed in the gateway, and is not reported to the server for further processing, so that the excellent function of the intelligent gateway of marginal calculation is realized.
Because the policy configuration information includes the policy decision, the policy condition and the policy action information, the gateway can determine the policy condition according to the device information and control and execute the action indicated by the policy action information according to the policy decision, such as enabling or disabling the device. Additionally, the policy action information may be a value indicating an action attribute for the linked device, wherein the action attribute value may be one or more of the following: action type, action delay, equipment port number and action strength value; therefore, the device corresponding to the device port number can be selected to execute the action of the action type corresponding to the action strength value, execute under the delay condition, and the like.
In some application scenarios, the user may wish to invoke the gateway to perform a corresponding operation even if the device information satisfies the policy condition, and may be implemented by a corresponding setting in the policy configuration information. As an example, a policy header may be included in the policy configuration information, the policy header including a policy identification and a policy state, and the action controlled by the gateway may be to include: judging whether the strategy state indicates a strategy activation state or a strategy deactivation state; and when the policy state indicates a policy inactive state, determining that the linked device does not need to be triggered to execute an action based on the policy decision, at which time the policy decision does not trigger execution of a corresponding gateway action even if the policy condition is satisfied.
More preferably, a threshold number of triggers may also be set in the policy header to control the number of times the gateway is triggered. Specifically, the triggering determination of the gateway action may be performed by counting the number of times that the linked device has been triggered, determining whether the counted number of times exceeds a triggering number threshold, and determining that the linked device does not need to be triggered to execute the action based on a policy decision when the counted number of times exceeds the triggering number threshold.
In some automated control processes of the gateway, in order to implement the periodic determination, a periodic policy period for instructing to perform determination for the device information may be set in the policy condition.
Since the device to which the gateway is connected may be plural, in order to achieve the association of control between the plural devices, plural pieces of policy configuration information may be set at the gateway, and the plural pieces of policy configuration information may be associated with each other. Specifically, the method may further include: judging whether the policy configuration information has the policy action information in the first policy configuration information matched with the policy condition in the second policy configuration information; and if so, judging whether the linked equipment needs to be triggered to execute the action indicated by the strategy action information in the first strategy configuration information and the second strategy configuration information or not based on the strategy decision. Thereby, a combination of the first policy configuration information and the second policy configuration information may be mobilized.
1 Structure of policy configuration information
Policy configuration information may be divided into four parts: policy header, policy decision logic, policy trigger conditions and policy enforcement actions:
1.1 policy header
The policy header mainly contains some policy main information.
1.2 policy decisions
The strategy decision is the core part of strategy control and mainly undertakes arithmetic operation and logic judgment of the strategy.
As a core part of the policy, the complex policy control often involves a very complex logic decision setting, and in order to improve the designability of the policy, a common embedded device development language, i.e., C language, is not adopted here. Considering that the lua script language has the characteristics of light weight, high efficiency, small occupied memory and weak language, the strategy decision part is designed by the lua language, a main function interface is provided for a user, and the user can self-design the decision logic of the strategy by using the grammar of a series of lua scripts such as the lua script language custom variable, the custom function and the like in the main function; meanwhile, the safety of the system is considered, the authority of the user is limited, and the reading and writing of the user to the system and the system call of the lua are shielded.
1.3 conditions of the strategy
The strategy conditions comprise the timing, the period and the triggering used in daily life; in the timing condition, a time mask and a week are introduced, so that the timing strategy is more flexible to set.
1.4 policy actions
In order to make the policy setting more concise, the policy action supports single equipment, and simultaneously, the support of equipment grouping and scenes is also expanded; meanwhile, the strategy action can also support the action of the strategy, so that the strategies can be interacted and operated, and the functionality and the flexibility of the strategies are greatly enhanced; in addition, the strategy also supports delayed action, and action characteristics of the strategy are enriched (for example, lights can be switched on and off by utilizing the delayed action to enable the lights to change linearly, so that sunrise and sunset simulation can be realized by using one strategy).
When the gateway operates the strategy, the strategy works in the gateway, so that the data is judged and processed at the source of the data without being reported to a platform server, the consumption of data transmission is reduced, and the strategy response is quicker. The communication between the strategy and the gateway internal application adopts the commonly used mqtt protocol in the field of Internet of things, and the strategy part is designed to be a monitoring type in consideration of the fact that the gateway often gathers a large amount of data.
2 policy trigger procedure
2.1 the user designs the head information, triggering conditions, decision judgment and execution actions of the strategy, and the head information, triggering conditions, decision judgment and execution actions can be issued to the gateway through the app and the platform server, the gateway strategy can be stored in a local database so that the user can add, delete, check and change the strategy subsequently, in addition, the user can change the activation state of the strategy at any time, and even can set the effective times of the strategy.
2.2 because the device information is reported to the gateway, the strategy monitors the data reported to the gateway by the device based on the mqtt bus in the gateway, and carries out local processing.
2.3 strategy conditions are triggered, a multithreading mode is adopted to process the strategies, and the problem that other strategies are lost when a plurality of strategies are triggered simultaneously is avoided; when designing a policy, it may require many conditions to be satisfied to decide whether the action of the policy is executed, and even the policy conditions may relate to the state of a certain device, at this time, the policy automatically operates and collects other unknown but necessary conditions to make a correct policy decision result
2.4 the policy result includes two types of actions, namely an action execution type and an action non-execution type, if the action is not executed, the policy continues to restore the monitoring mode, waits to be triggered, if the action is executed, the action part in the policy body is inquired, whether the action target is a single device or a certain group, or whether a certain scene or even another policy is possible is judged, then, the time delay of the action is judged for execution, and finally, a correct action is made; when the action target is a strategy, a combined strategy is formed, and simple strategies are combined to realize complex strategy control logic, so that the modularization of the strategy is realized.
The 2.5 policy is to push a special character "null" to a given user interface function main for an offline device to inform the user, and if the user cares about a possible malfunction caused by the offline device, the user can process the null in policy decision according to whether the null is present or not.
The simple application example of one aspect of the strategy is described by simulating natural light of the agricultural greenhouse, in one strategy, a header trig is set to be 1, the strategy is executed only once, a state is 1, the strategy is enabled (trig = =1, the state is automatically set to be 0 after the strategy is executed once, and a user does not need to process), code and serial are respectively a data packet type and a data packet number, and ct is strategy creation time; the # in cond represents the mask of the day of the week, type represents the condition type, and ep represents different ports of the same device; act represents action, type represents action type, delay represents delay, bri, val represent setting brightness and its value respectively; exp is a function described by lua of policy decision (only simple comparison is made here, and user-defined new function variables and arithmetic and logic operations can be supported), and the effect of the whole policy implementation is that the implementation is started (validated) at the time specified by cond, the lamp brightness is increased by 20 to 40 every 3600s, and the user can implement more accurate linear (or nonlinear) light change to simulate the sunlight change with smaller time setting.
Preferably, the user may design trig =0, which represents an infinite number of times of effects, set the cond time to # - # - # -08-11-11- #, and implement the strategy to be started 11 minutes and 11 seconds at 8 points every day, or may implement the same effect by matching with the periodic strategy and letting the periodic condition.
In other application scenarios, linkage between different policies in the gateway and handling of group and conditional device offline problems may be implemented. Specifically, two devices may be set in cond in the policy configuration information, "cmd" indicates a device determination attribute, i.e., airtemperature; the strategy decision exp is described by lua, since each device relates to an actual value and a comparison value (val setting inside cond), 4 parameters are pushed to a main entry function, a represents the actual value, b represents the comparison value, the whole strategy has the effect that two sensors collect air temperature values, then an average value is calculated, an offline sensor (sensor fails) cannot participate in average value calculation, if both sensors are offline, the strategy is not executed, and if the calculation result of the average value is less than 200, the strategy is executed; the policy action is: the delay 30s turns on all the device switches with the group number 5 (different types of devices can be divided into one group), and immediately (with the delay set to 0) the policy with the policy number 101 is enabled during the policy execution, at this time, the policy 101 starts to monitor and judge, and if the policy execution condition is met, the action of the policy 101 is executed. It is to be understood that in the description of this embodiment, the policy is enabled, and the policy that is not in effect (sleep) is enabled, and similarly, the policy that is in effect may be put into the non-effect (sleep) mode; in addition, only packet control is shown here, and similarly, control of the scene can also be realized.
