Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of 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 obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, in one embodiment, a protocol conversion system includes a server 2 and a gateway device 1, and the operation of the system is as follows:
the gateway device 1 sends a request to the server 2 to obtain the conversion protocol script of the target smart device. Specifically, the gateway device 1 acquires the conversion protocol script supported by the target intelligent device from the server 2 before converting the interaction information between the target intelligent device and the server 2, so that the gateway device 1 first sends an acquisition request to the server 2, and the server 2 sends the required script to the gateway device 1.
The server 2 receives the request and extracts a target conversion protocol script corresponding to the target intelligent device according to the conversion protocol script request, wherein the target conversion protocol script comprises a parent script and a child script, the parent script and the child script establish an attribution relation according to the type of the intelligent device, the intelligent devices of the same type correspond to one parent script together, and the conversion protocol corresponding to each intelligent device and the difference part between the conversion protocols in the parent script to which the intelligent device belongs form the child script of each intelligent device. Specifically, since more than 95% of the conversion protocol codes of the intelligent devices of the same type are the same (for example, the conversion protocols of all air conditioners are substantially the same, and the conversion protocols of all washing machines are substantially the same), in the embodiment of the present invention, in order to reduce the number of the conversion protocol scripts and the file size, a standard conversion protocol parent script is configured in advance for the intelligent devices of the same type, so that the conversion protocol parent script can meet most control functions of most devices. And then, aiming at the intelligent equipment of the same type, sequentially aiming at the equipment model of each equipment, analyzing the difference between the corresponding actual conversion protocol and the conversion protocol in the parent script, if no difference exists, the child script is empty, and if the difference exists, the corresponding difference code is configured into the child script corresponding to the equipment model. Therefore, the data volume in the sub scripts is very small, the same type of intelligent equipment only needs one father script, then the father script and each sub script in the same equipment type are associated, the attribution of the father script and the sub script is determined, and therefore flexible calling can be achieved. For example: the temperature range of common air conditioners is 16-30 degrees, a special air conditioner a2_ conditionioner only supports 20-28 degrees, conditions are added into a sub script of a2_ conditionioner, and the other is based on a parent script.
The server 2 transmits the target conversion protocol script to the gateway apparatus 1.
The gateway apparatus 1 receives the target conversion protocol script.
The gateway device 1 converts the interaction information between the target intelligent device and the server 2 through the sub-script.
If the conversion of the interaction information by the sub-script fails, the gateway device 1 converts the interaction information between the target intelligent device and the server 2 by using the parent script corresponding to the sub-script.
Specifically, after receiving the conversion protocol script supporting the target intelligent device, the gateway device 1 first tries to convert the interaction information between the target intelligent device and the server 2 by using the sub-script, and if the converted interaction information is just the interaction function supported by the code in the sub-script, the conversion is directly performed. And if the converted interactive information does not correspond to the codes in the sub-script, switching to the parent script to convert the interactive information. For example: if the set is the air-conditioning mode, the sub script only contains the air-conditioning temperature of the difference part, and no air-conditioning mode exists, so that the sub script can fail to be converted, and the parent script is switched to convert the interactive information of the air-conditioning mode.
Specifically, in an embodiment, in the system, the gateway device 1 sends a request for acquiring a conversion protocol script of the target intelligent device to the server 2; the server 2 receives the request and extracts a target conversion protocol script corresponding to the target intelligent device according to the conversion protocol script request, and the specific working process is as follows:
the gateway apparatus 1 acquires the apparatus model of the target intelligent apparatus.
The gateway device 1 generates a conversion protocol script request carrying the device model based on the device model, and sends the conversion protocol script request carrying the device model to the server 2.
The server 2 receives a protocol conversion script request;
the server 2 analyzes the equipment model of the target intelligent equipment in the conversion protocol script request;
the server 2 determines the device type based on the device model, and searches out a parent script matching the device type and a child script matching the device model from a preset conversion protocol script database.
Specifically, when the gateway device 1 downloads the conversion protocol scripts from the server 2, it is practically impossible to download all the conversion protocol scripts stored in the server 2, and the gateway device 1 has no large storage space and does not need to download most of the scripts because they are not used. Therefore, before the conversion protocol script is obtained from the server 2, the device model of the target smart device is first obtained, for example: the intelligent equipment which is distributed with the network through the gateway equipment 1 at present comprises a washing machine, an air conditioner, a sound box and a curtain, the gateway equipment 1 obtains the equipment models of the four intelligent equipment, then generates a conversion protocol script obtaining request carrying models aiming at the four equipment, and sends the request to the server 2, so that the server 2 analyzes the four equipment models in the request, and then sends a sub script and a father script corresponding to the equipment models to the gateway equipment 1, thereby avoiding the storage of redundant information in the gateway equipment 1.
Through the components, according to the technical scheme provided by the application, a unified conversion protocol script is configured for the intelligent devices of the same type to serve as a parent script, and then for the intelligent devices of the same type and different types, if the conversion protocol of the type is different from the conversion protocol in the parent script, the different part is independently written into the sub script of the intelligent device of the corresponding type. Therefore, when the gateway equipment manages the intelligent equipment, the corresponding father script and the corresponding son script are obtained from the server only according to the currently configured intelligent equipment model, and the intelligent equipment with the same equipment type only needs to obtain one father script and a plurality of son scripts with very small data volume, so that the data volume of the conversion protocol script is greatly reduced, and the management and maintenance difficulty of the gateway equipment management on the conversion protocol script is greatly reduced. When the gateway equipment converts the interactive information between the server and the intelligent equipment, the sub-script is firstly used for conversion, if the interactive information needing to be converted is found not to belong to the range limited by the conversion protocol in the sub-script, the parent script is used for converting the interactive information when the conversion fails, and therefore the interactive information can be accurately converted.

For example: in this embodiment, the server transmits control instruction information for adjusting the temperature up to the air conditioner, and the gateway device performs protocol conversion on the information into a format that can be recognized by the air conditioner, i.e., target control information. And then the air conditioner responds to the target control information to adjust the temperature by one degree, the current air conditioner temperature is fed back to the gateway equipment as state information, and then the gateway equipment converts the state information into target state information which can be identified by the server so as to inform the server of the temperature value of the current air conditioner.
