In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The intelligent home equipment manufactured by each manufacturer may have its own status information transmission protocol, usually, a code in the local gateway can be converted into a protocol recognizable by the platform provider background server according to the equipment model attribute name of each manufacturer, and when detecting that the intelligent home equipment is accessed, the local gateway can perform status information conversion according to the transmission protocol negotiated by the equipment provider and the platform provider. When the intelligent household equipment accessed to the local gateway performs product iteration, the protocol conversion codes of the local gateway need to be modified to match the functions of the new product, and the codes of all the protocol conversion codes needing the functions are upgraded; when a new smart home device is accessed, a protocol conversion code corresponding to the smart home device needs to be developed, and code upgrading is performed on the local gateway. Therefore, as long as the protocol of the smart home device is changed, the existing protocol conversion method needs to update the codes of the local gateway, and particularly, when the version of the smart home device is iterated frequently, the codes of the local gateway need to be updated frequently, so that the protocol conversion efficiency is seriously affected, and the access speed of the smart home device is low.
Based on the technical scheme, the protocol conversion script corresponding to each type of target equipment is generated by the server, when the target equipment is accessed to the local gateway, the local gateway can obtain the protocol conversion script corresponding to the target equipment from the server, and the protocol conversion script is adopted to convert the interactive instruction between the server and the target equipment into target interactive information which can be identified by the server and the target equipment, so that code development or code upgrading is avoided at the local gateway, and the protocol conversion efficiency and the access speed of the target equipment are ensured.
In accordance with an embodiment of the present invention, there is provided an embodiment of a protocol conversion method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
In this embodiment, a protocol conversion method is provided, which can be used in a local gateway, and fig. 1 is a flowchart of a protocol conversion method according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
and S11, acquiring a protocol conversion script corresponding to each type of target equipment, wherein the protocol conversion script is used for providing a conversion interface between the server attribute and each target equipment attribute.
The protocol conversion script is an executable file written according to a certain format, and the protocol conversion script corresponds to the model of the target device. Protocol conversion scripts are usually stored in text (ASCII) in the server and are only interpreted or compiled when called by the local gateway. The protocol conversion script comprises conversion interfaces of server attributes and each target device attribute.
The target equipment is intelligent household equipment which is accessed to the local gateway, such as an intelligent air conditioner, an intelligent curtain and the like. When the target device accesses the local gateway, the local gateway may call a protocol conversion script corresponding to the model of the target device from the server, and store the protocol conversion script in the local gateway.
And S12, converting the interactive instruction between each target device and the server based on the protocol conversion script to obtain target interactive information.
The interactive instruction is interactive information between the server and the target device, and comprises a control command issued by the server to the target device and state information reported by the target device to the server. The control command is a function instruction for controlling the target device, and the state information is current running state information of the target device.
The server and the target device communicate data through the local gateway. The local gateway can convert the control command issued by the server to the target device through the protocol conversion script to obtain the target identification command which can be identified by the target device. Meanwhile, the local gateway can convert the state information reported by the target equipment to the server through the protocol conversion script to obtain the target identification information which can be identified by the server. The target identification information and the target identification command form target interaction information.
And S13, performing communication between each target device and the server based on the target interaction information.
The local gateway converts the control command into a target identification command, and then can send the target identification command to the target equipment, after receiving the target identification command, the target equipment adjusts the running state of the target equipment according to the target identification command, feeds back information of successful control to the local gateway, and sends equipment state information of successful control to the local gateway, and the local gateway can convert the equipment state information to obtain target identification information which can be identified by the server, and sends the target identification information to the server, so that communication between the server and the target equipment is realized.
Taking the intelligent air conditioner as an example, when a user wants to adjust the temperature of the intelligent air conditioner accessed to the local gateway, the server may receive a control command sent by the user, send the control command to the local gateway for conversion, obtain a target identification command that the intelligent air conditioner can identify, and send the target identification command to the intelligent air conditioner by the local gateway. When the intelligent air conditioner receives the target identification command, temperature adjustment can be carried out according to the target identification command, the adjusted temperature information is fed back to the local gateway, the local gateway converts the temperature information to obtain target identification information which can be identified by the server, and the target identification information is sent to the server, so that the current state information of the intelligent air conditioner is determined by the server and is fed back to a user through an APP connected with the server.
In the protocol conversion method provided by this embodiment, the local gateway performs command conversion on the interactive instruction between the target device and the server through the protocol conversion script, and when the target device performs version change or a new device accesses the gateway, only the protocol conversion script needs to be updated at the server, thereby avoiding code modification or code upgrade in the local gateway, ensuring protocol conversion efficiency, and improving the access speed of the target device.
In this embodiment, a protocol conversion method is provided, which can be used in a local gateway, and fig. 2 is a flowchart of a protocol conversion method according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
and S21, acquiring a protocol conversion script corresponding to each type of target equipment, wherein the protocol conversion script is used for providing a conversion interface between the server attribute and each target equipment attribute. For a detailed description, refer to the related description of step S11 corresponding to the above method embodiment, which is not repeated herein.
Specifically, the step S21 may include the following steps:
s211, sends the request information of the protocol conversion script to the server.
The request information is instruction information of a local gateway request server feedback protocol conversion script. When the target device accesses the local gateway, the local gateway may request the server for a protocol conversion script corresponding to the model of the target device to enable communication between the target device and the server.
S212, receiving the protocol conversion scripts of the target devices of all models returned by the server.
After receiving the request information sent by the local gateway, the server may feed back, to the local gateway, the protocol conversion script corresponding to the request information based on the request information, where the request information includes all models of the target device. The local gateway can receive the protocol conversion scripts corresponding to all models of target devices fed back by the server.
Specifically, when the protocol conversion script is updated or a new model target device is accessed, as shown in fig. 3, the step S21 may include the following steps:
s213, receiving the update information sent by the server.
And updating the message that the protocol conversion script of the target equipment is changed or the target equipment accessed to the local gateway is the target equipment with the new model. The target device of the new model may be a new type device, or may be a new type device of the same type.
When a new protocol function is added to a target device of a certain model, the corresponding protocol conversion script also needs to be updated, at this time, the protocol conversion script in the server is updated, and the server can send update information to the local gateway, so that the local gateway updates the stored protocol conversion script.
When the target device is accessed to the local gateway for the first time, the server can obtain the protocol conversion script corresponding to the target device and send the update message to the local gateway, so that the local gateway can timely obtain the protocol conversion script corresponding to the target device accessed for the first time.
S214, when the protocol conversion script is in an unused state, sending script updating request information to the server based on the updating information, wherein the script updating request information is used for requesting to acquire the updated protocol conversion script.
Since the local gateway may use the protocol conversion script when the local gateway receives the update message of the protocol conversion script, an operation failure may be caused if the protocol conversion script is directly updated. Therefore, the local gateway needs to be able to send script update request information to the server based on the update information when the protocol conversion script to be updated is in an unused state, so as to request to acquire the updated protocol conversion script.
S215, receiving the updated protocol conversion script sent by the server.
After receiving the script update request information sent by the local gateway, the server may feed back, to the local gateway, the protocol conversion script corresponding to the script update request information based on the script update request information. The local gateway may then receive the updated protocol conversion script sent by the server.
And S22, converting the interactive instruction between each target device and the server based on the protocol conversion script to obtain target interactive information.
Specifically, the step S22 may include: carrying out protocol conversion on a control command issued by a server to obtain a target identification command which can be identified by target equipment; and/or carrying out protocol conversion on the equipment state information reported by the target equipment to obtain target identification information which can be identified by the server.
The target identification command is a control command that the target device converted by the protocol conversion script can recognize. The local gateway can perform protocol conversion on the control command issued by the server to obtain a target identification command which can be identified by the target equipment, and sends the target identification command to the target equipment so that the target equipment performs function control according to the target identification command, and sends equipment state information of the target equipment to the local gateway.
The target identification information is setting state information that can be recognized by the server subjected to the protocol conversion script conversion. The local gateway can perform protocol conversion on the device state information reported by the target device to obtain target identification information which can be identified by the server, and sends the target identification information to the server so that the server can obtain the running state of the target device in real time.
And S23, performing communication between each target device and the server based on the target interaction information. For a detailed description, refer to the related description of step S13 corresponding to the above method embodiment, and are not repeated herein.
In the protocol conversion method provided by this embodiment, when the protocol conversion script corresponding to the model of the target device changes or a new model device accesses the local gateway, the server may send update information to the local gateway to obtain the latest protocol conversion script corresponding to the target device. By acquiring the latest protocol conversion script of the target equipment, the gateway codes are prevented from being modified when the protocol is updated or new equipment is accessed, so that code development or code upgrading is prevented from being carried out on a local gateway, the working efficiency of workers and the protocol conversion efficiency are improved, and the access speed of the target equipment is accelerated.
Carrying out protocol conversion on a control command issued by a server to obtain a target identification command which can be identified by target equipment; and/or carrying out protocol conversion on the device state information reported by the target device to obtain target identification information which can be identified by the server, thereby realizing data communication between the target device and the server and further ensuring the access speed of the target device.
In this embodiment, a protocol conversion method is provided, which can be used in a server, and fig. 4 is a flowchart of a protocol conversion method according to an embodiment of the present invention, as shown in fig. 4, where the flowchart includes the following steps:
and S31, sensing the model of each target device.
The model is used for representing the attribute of the target device, and the server can sense the model of each target device to determine the attribute of each target device.
S32, based on the model of each target device, a protocol conversion script corresponding to each model of target device is generated.
The server may determine the attributes of each target device based on its perceived model of each target device. And the server respectively creates protocol conversion scripts of the target equipment of each model according to the attributes of the server and the attributes of each target equipment so as to generate interfaces between the attributes of the server and the attributes of each target equipment.
In the protocol conversion method provided by this embodiment, the server generates, by sensing the model of each target device, a protocol conversion script corresponding to each model of the target device based on the model of each target device, and the protocol conversion script includes an interface for performing mutual conversion between the attribute of the target device and the attribute of the server. When the target equipment is accessed to the local gateway, the server can obtain the protocol conversion script corresponding to the model of the target equipment, so that code development or code upgrading of the local gateway is avoided, the protocol conversion efficiency is guaranteed, and the access speed of the target equipment is increased.
In this embodiment, a protocol conversion method is provided, which can be used in a server, and fig. 5 is a flowchart of a protocol conversion method according to an embodiment of the present invention, as shown in fig. 5, the flowchart includes the following steps:
and S41, sensing the model of each target device. For a detailed description, refer to the related description of step S31 corresponding to the above method embodiment, and are not repeated herein.
S42, based on the model of each target device, a protocol conversion script corresponding to the model of each target device is generated.
Specifically, the step S42 may include the following steps:
s421, judging whether the protocol conversion script corresponding to each model of target device is updated or not, or whether a new model of device is accessed or not.
The server can acquire whether the function protocol is newly added to the target equipment of each model in real time, and accordingly whether the protocol conversion script of the target equipment of each model is updated is determined. Specifically, if a function protocol is added to a certain model of target device, it may be determined that the protocol conversion script of the model of target device is updated, and step S422 is executed.
The server may also traverse the protocol conversion script it generates to determine whether the current target device is a new model device.
