It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Example 1
In this embodiment, a method for sending a control instruction running on a server is provided, and fig. 1 is a flowchart of the method for sending a control instruction according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S101, receiving a control request, and generating a standard control instruction according to the control request, wherein the standard control instruction is an instruction adapted to the server, and the standard control instruction indicates an attribute to be controlled of a controlled terminal and an operation target of the attribute to be controlled;
step S103, converting the format of the standard control instruction according to a pre-configured mapping file to obtain an adaptation control instruction, wherein the mapping file is used for indicating the format mapping relationship between the standard control instruction and the adaptation control instruction, and the format of the adaptation control instruction is a format recognizable by the controlled terminal;
step S105, sending the adaptive control instruction to the controlled end, where the adaptive control instruction is used to instruct the controlled end to execute the operation corresponding to the operation target on the control target attribute.
According to the embodiment of the invention, as the control request is received, and the standard control instruction is generated according to the control request, wherein the standard control instruction is an instruction adapted to the server, and the standard control instruction indicates the attribute to be controlled of the controlled terminal and the operation target of the attribute to be controlled; converting the format of the standard control instruction according to a pre-configured mapping file to obtain an adaptation control instruction, wherein the mapping file is used for indicating the format mapping relationship between the standard control instruction and the adaptation control instruction, and the format of the adaptation control instruction is a format which can be recognized by the controlled terminal; sending the adaptive control instruction to the controlled terminal, wherein the adaptive control instruction is used for instructing the controlled terminal to execute the operation corresponding to the operation target on the control target attribute, namely, the instruction format adapted by the server is set at the server, if the server needs to issue an instruction to the access device (namely, the controlled terminal), the server only needs to uniformly package the control instruction in a standard format, and then the standard control instruction of the server is subjected to format conversion and converted into the instruction format of the adaptive access device, so that the server does not need to package instructions in different formats, and the load of the server is reduced; only one interface can exist between the server and the controlled end, so that resource consumption is reduced, and even if new access equipment needs to communicate with the server, a new adaptive interface does not need to be added, so that the problem of resource consumption caused by different interfaces of the access equipment of the internet of things in the related art can be solved, and the technical effects of simplifying equipment management logic and reducing resource consumption are achieved.
In an exemplary embodiment, the control request may be sent by a control end (e.g., a terminal) to a service end, where the control request indicates an attribute to be controlled of a controlled end and an operation target of the attribute to be controlled, for example, the control end may be a mobile terminal such as a mobile phone, the controlled end may be a smart home device, and the service end may be a cloud end. The mobile terminal sends a control request to the cloud end, and the cloud end sends a control instruction to the intelligent household equipment according to the control request.
It should be noted that, in the case that there are multiple different controlled terminals, the control instruction received by each controlled terminal may be obtained by converting a standard control instruction by the service terminal.
In an exemplary embodiment, before converting the standard control command into a format according to a pre-configured mapping file to obtain an adaptive control command, the method further includes: performing command compensation on the standard control command, wherein performing the command compensation comprises: and compensating a correlation instruction for the standard control instruction, wherein the correlation instruction is an instruction which has a preset first correlation with the standard control instruction.
The standard control command may be a simple command, and when the control target is to be achieved, other related commands need to be linked, so that the related commands need to be compensated for the standard control command in order to achieve the control target.
In an exemplary embodiment, the association instructions include the following: a compensation attribute, and an operation target for the compensation attribute; the compensation attribute is an attribute having a preset second association relationship with the attribute to be controlled indicated in the standard control instruction in the attributes of the controlled end.
It should be noted that the standard control instruction generated by the server may be a simple control instruction, and may include only one or a small number of attributes, for example, which may be used to directly instruct the controlled end to perform a specified operation on the specified attribute to achieve the operation target. For example, the standard control command may be a wider command, for example, a command for controlling (e.g., switching) the operation mode of the controlled terminal. For example, the server may generate a standard control command indicating a "washing mode", and if the controlled terminal wants to achieve the control target, it may need to perform coordinated control on multiple attributes, so that the server needs to perform control command compensation on the standard control command, such as compensation on specific attributes associated with "washing", for example, attributes of washing time, washing speed and the like of the washing machine, and also needs to compensate operation target information of the control command, for example, washing time value, speed value and the like of the washing machine. For another example, if the controlled terminal is an air conditioner, and if the control request indicates to switch heating to the cooling mode, it means that the electric heating state of the air conditioner is turned off, and there may also be a change in wind speed and wind swing direction, which means that the function of switching modes, the air conditioner executes a set of control instructions. In this case, the server may generate only one simple standard control instruction for indicating the switching mode, and other linkage attributes, such as the electrical heating state, the wind speed, the temperature, and the like, are automatically assembled by the server, and the attribute value may be obtained from the state reported by the device.
In an exemplary embodiment, before performing the command compensation on the standard control command, the sending method of the control command further includes: and acquiring the current attribute value of the compensation attribute, and taking the current attribute value of the compensation attribute as an operation target of the compensation attribute. It should be noted that, if in some cases, the attribute value of some compensation attribute does not need to be changed, the current value of the compensation attribute can be directly compensated to the standard control command.
In an exemplary embodiment, before obtaining the current attribute value of the compensation attribute, the sending method of the control instruction further includes: receiving and caching current state information reported by the controlled terminal to obtain caching information, wherein the current state information comprises an attribute of the controlled terminal and a current attribute value of the attribute;
obtaining a current attribute value of the compensation attribute, including: and obtaining the current attribute value of the compensation attribute from the cache information.
It should be noted that the compensation attribute may be some attribute information of the controlled terminal reported in advance, and may be directly reported to the server or reported to a device of a third party, and may be obtained from the device of the third party when the server needs the information.
In an exemplary embodiment, before the format converting the standard control command according to the pre-configured mapping file to obtain the adaptive control command, the method further includes: and performing logic correction on the standard control instruction according to preset logic correction information.
The logic correction information may correct the logic of the standard control command, for example, correct a control command having a logic error. For example, when the air conditioner is switched from a heating mode to cooling, the temperature range is changed from 20-30 degrees to 15-25 degrees. In the case that only switching to the cooling mode is indicated in the control request, assuming that the current state of the controlled device is 26 degrees, the cloud (i.e., a server) will modify the temperature to a temperature value within the value range of the cooling mode, and this value may be defined as a default value in the configuration file.
For example, the server in this embodiment may be a single server, or a server cluster composed of multiple servers, or a cloud server, such as a cloud.
According to another embodiment of the present invention, there is also provided a method for receiving a control instruction, which may be applied to a terminal, and fig. 2 is a flowchart of the method for receiving a control instruction according to the embodiment of the present invention, as shown in fig. 2, the method includes:
step S202, receiving an adaptation control instruction sent by a server, wherein the format of the adaptation control instruction is a format recognizable by the controlled terminal, the adaptation control instruction is obtained by the server performing format conversion on a standard control instruction according to a pre-configured mapping file, the mapping file is used for indicating a format mapping relationship between the standard control instruction and the adaptation control instruction, the standard control instruction is generated by the server according to a control request after receiving the control request, the standard control instruction is an instruction adapted to the server, and the standard control instruction indicates an attribute to be controlled of the controlled terminal and an operation target of the attribute to be controlled;
step S204, executing the operation corresponding to the operation target on the control target attribute according to the adaptive control instruction.
Through the steps, as the server is provided with the instruction format adapted to the server, if the server needs to issue an instruction to the access device (namely, the controlled terminal), the server only needs to uniformly package the control instruction into a standard format, and then performs format conversion on the standard control instruction of the server to convert the standard control instruction into the instruction format adapted to the access device, so that the server does not need to package instructions with different formats, and the load of the server is reduced; only one interface can exist between the server and the controlled end, so that resource consumption is reduced, and even if new access equipment needs to communicate with the server, a new adaptive interface does not need to be added, so that the problem of resource consumption caused by different interfaces of the access equipment of the internet of things in the related art can be solved, and the technical effects of simplifying equipment management logic and reducing resource consumption are achieved.
In an exemplary embodiment, the adaptive control command is obtained by performing the format conversion after the server performs command compensation on the standard control command, where performing the command compensation includes: and compensating a correlation instruction for the standard control instruction, wherein the correlation instruction is an instruction having a preset first correlation with the standard control instruction.
In an exemplary embodiment, the association instructions include the following: a compensation attribute, and an operation target of the compensation attribute; the compensation attribute is an attribute having a preset second association relationship with an attribute to be controlled indicated in the standard control instruction in the attributes of the controlled end.
In an exemplary embodiment, the operation target of the compensation attribute is determined by the server side obtaining the current attribute value of the compensation attribute, and the current attribute value can be used as the attribute value of the compensation attribute.
In an exemplary embodiment, the current attribute value of the compensation attribute is obtained by the server from cache information reported by the controlled end, where the cache information includes current state information of the controlled end, and for example, the current state information includes the attribute of the controlled end and the current attribute value of the attribute.
In an exemplary embodiment, the adaptive control instruction is obtained by performing logic modification on a standard control instruction according to preset logic modification information and then performing format conversion on the standard control instruction by the server.

Example embodiments
The following further explains the embodiments of the present invention with reference to specific scenarios:
after the access device accesses the internet of things, the data flow of the cloud (equivalent to the server in the above embodiment) may be rich and diverse. The access device may refer to a device accessing to the internet of things, for example, various terminals in the home internet of things. The control commands to access the cloud end network device can be numbers with different lengths, can be meaningful English words or simple English translations. That is, the control instruction formats supported by different access devices may be different.
For example, in the present embodiment, the 6-bit code device may be a device that instructs 6-bit numbers. The standard device is a device with instructions for english words. In the related art, the operation of the 6-bit code device is realized through one set of interface, and the standard device is realized through another set of different interface. In the actual use process, the processing logic is relatively complex. In addition, when the device is newly accessed, if the existing service does not support the newly accessed device, a new interface needs to be developed, which is not beneficial to expansion.
The present embodiment provides a technical solution for controlling a device, which can be operated in the following scenario, for example: the scene comprises a server, an access device to be controlled and a controller (also called a service side). The control party can send a control instruction to the server to realize the control of the access equipment to be controlled through the server; after receiving the control command of the control party, the server may perform some compensation or modification processing on the control command to form a complete command, and then convert the processed control command into a command format suitable for the access device to be controlled, and send the command format to the access device to be controlled.
For example, the controller may be a software application with a control function, for example, an application with a control function (such as a client), through which an instruction is sent to the server to implement control of other devices; the controller may also be a terminal with a control function, such as a terminal carrying an application with a control function, and the terminal sends an instruction to the server to implement control of other devices. The terminal in this embodiment may be a terminal device configured with a target client, and may include, but is not limited to, at least one of the following: mobile phones (such as Android phones, iOS phones, etc.), notebook computers, tablet computers, palm computers, MID (Mobile Internet Devices), PAD, desktop computers, smart televisions, etc. The target client may be an instant messaging client, a browser client, a control client, etc. Such networks may include, but are not limited to: a wired network, a wireless network, wherein the wired network comprises: a local area network, a metropolitan area network, and a wide area network, the wireless network comprising: bluetooth, WIFI, and other networks that enable wireless communication.
For example, the access device to be controlled may be a smart home device in a home internet of things, such as a refrigerator, an air conditioner, a washing machine, and the like.
Illustratively, the server may be a single server, or a server cluster composed of a plurality of servers, or a cloud server.
The scheme provided by the embodiment designs a control instruction in a standard format (hereinafter referred to as a standard control instruction), and the control instruction in the standard format is generated by assistance of a configuration file. The control instruction with the standard format is used for interaction and circulation of the internal information of the server. The configuration file comprises a logic constraint file corresponding to the standard control instruction and a mapping file used for converting the standard control instruction and the control instructions with different protocols and different formats. The logic constraint file is used for compensating and correcting the standard control command, and the mapping file is used for converting the format of the standard control command into a command suitable for the access equipment to be controlled.
For example, if the air conditioner (i.e., an access device to be controlled) is a 6-bit code device, only 6-bit digital commands can be recognized. And after receiving the control instruction, the cloud end matches the logic constraint file to find the group control instruction, and fills attributes such as modes, wind degrees, wind pendulum and the like according to a group control instruction list and the current state of the equipment to obtain a complete group control instruction. Then, it is determined whether the group control command needs to be modified in the current state according to a mutex condition (a logic modification information, which is also a part of the logic constraint file), for example, when the current air conditioner is in pmv mode, the temperature cannot be set, and if the group control command includes the content of the temperature control command, the group control command needs to be modified, that is, the content of the temperature control command in the group control command needs to be deleted. If the control instruction can be issued after correction, the group control instruction is converted according to the mapping file, the group control instruction in the standard format is adapted to be the 6-bit code control instruction, and finally the group control instruction is issued to the air conditioner through the control channel. And (5) the air conditioner responds normally and is adjusted to the target temperature.
The embodiment of the invention supports the issuing of the standard model control instruction (equivalent to the standard control instruction) in a configuration file form by defining a set of standards. At least one of the following may be defined in the configuration file: mapping information, logic constraint information and the like, wherein the logic constraint information can comprise attribute information of the equipment, group control instruction operation information, logic correction information and the like. The control instructions issued in the attribute information correspond to the control instructions actually supported by the device one to one. The logical constraint information specifies a change in the attribute information in the current device state. The new interface of the domain model service aims at 6-bit codes and standard equipment, and the standard model is used for controlling and acquiring the equipment state interface.
Fig. 6 is a flowchart illustrating a process of issuing a control command according to an exemplary embodiment of the present invention, as shown in fig. 6:
both the resource server and the application server (App server) in the figure can provide services and act as a server side. The resource server can store configuration files;
a shadow device: standard model data of the device (i.e., data that can be used to generate standard commands) is provided externally, and the shadow (i.e., cache) of the device in the cloud is provided. After the device reports its own state or attribute to the shadow device, because the device reports the state or attribute by using its own instruction and command format, the shadow device needs to convert the instruction of the state or attribute reported by the device into a standard instruction, for example, perform an operation of converting a 6-bit code instruction into the standard instruction, and provide standard model data (i.e., data of the standard instruction) to the outside; thus, the developer will only obtain device data in the standard model manner.
A domain model: the method can be a service of a server side, and can complete conversion from a standard code to a 6-bit code, automatic compensation of equipment attribute values, completion of group control instructions and logic operation according to constraints. Other attributes and attribute values need to be supplemented by the domain model service, and the attribute values are obtained from the shadow device, so that a developer does not need to care whether the numerical values are repaired or not. In which constraints are used to describe logical modifications formed during operation of the device, for example, when the air conditioner is switched from heating mode to cooling, the temperature range may become smaller.
When the application server (App server) issues the operation control instruction of the standard model, a single attribute or a part of attributes can be sent, so that a developer can directly send the operation control instruction without acquiring the equipment state. Wherein the device comprises a 6-bit code and a standard device. The App server issues the standard control command to the domain model, the domain model completes control command encapsulation, and the control command is issued to the equipment through the gateway.
