When the server and the intelligent gateway cannot communicate, the intelligent gateway 201 and the intelligent gateway 202 directly communicate to perform data interaction.

Or the intelligent gateway 202 sends the device attribute data of the controlled device 204 accessing the intelligent gateway 202 to the intelligent gateway 201. It can be understood that, in the case that communication cannot be performed between the server and the intelligent gateway, the intelligent gateway 201 and the intelligent gateway 202 directly communicate to perform data interaction, so that the device attribute data of the controlled device can be synchronized to each intelligent gateway, for example, the intelligent gateway 102 or the intelligent gateway 103, in time, and therefore all the controlled devices accessing the intelligent gateway can be controlled through the intelligent gateway 102 or the intelligent gateway 103.

It should be noted that, as can be seen from fig. 1 or fig. 2, the method is applied to a process in which a data sending end performs data interaction to a data receiving end (i.e., an opposite-end communication object). The data sending end refers to a communication object for sending data to be transmitted. The data receiving end refers to a communication object for receiving data to be transmitted, namely an opposite-end communication object. The data sending end comprises at least one of a server and an intelligent gateway, and the data receiving end comprises at least one of a server and an intelligent gateway. The data sending end sends data as at least one of the following conditions: the server sends data to the intelligent gateway, the intelligent gateway sends data to the server, the intelligent gateway sends data to the intelligent gateway, and the server sends data to the server.
In some embodiments, as shown in fig. 3, a data transmission method applied to an intelligent home system is provided, and for example, when the method is applied to a server or an intelligent gateway in fig. 1 or fig. 2, that is, a data sending end, the method includes the following steps:
The data sending end refers to a communication object for sending data to be transmitted, and includes but is not limited to at least one of a server and a medium communication object in an intelligent gateway.
The data to be transmitted is data waiting for the data sending end to send. I.e. data waiting for the server or the intelligent gateway to send.
In some embodiments, the data to be transmitted includes at least one of control data and non-control data. The control data is data for controlling a controlled device or an intelligent gateway. Non-control data is data that is not related to the control of the controlled device or intelligent gateway.
In some embodiments, the non-control data includes at least one of target device attribute data and non-device attribute data.
Illustratively, the data sending end generates data to be transmitted based on an intelligent home communication protocol.
In some embodiments, the smart home communication protocol generates data to be transmitted based on a json (JavaScript Object Notation) format, where the data to be transmitted includes at least one of a field name and a field value.
In some embodiments, the data to be transmitted includes the following:
{
“device Id”：“dff6f2f0cb2d4005a6cd98882f6c6e”，
"device name": a lamp belt,
“room Id”：“d84cbd1240cf4e65b7a268af14c25a33”，
"floor Name": 'the first floor',
}
wherein "device Id (device number)", "device Name", "room Id (room number)", and "floor Name" are field names.
"dff6f2f0cb2d4005a6cd98882f6c6e", "d84cbd1240cf4e65b7a268af14c25a33", "light strip" and "first floor" are field values. It will be appreciated that the colon: preceding is the field name, colon: followed by a field value.
And the target field name is the equipment attribute name in the target equipment attribute data. It will be appreciated that the target field name is associated with the device type of the controlled device.
The target device attribute data is related attribute data describing controlled devices in the smart home system.
The device attribute name is an attribute name inherent to the controlled device. That is, the device attribute names of different controlled devices are related to the device types of the controlled devices.
In some embodiments, the target field name includes at least one of a controlled device name, a name of an intelligent gateway to which the controlled device has access, a floor number where the controlled device is located, a room number where the controlled device is located, and the like. It can be understood that the device attribute name of the controlled device accessing the intelligent gateway does not change once it is defined, that is, the device attribute name of the controlled device is not changed during each transmission of the related attribute data of the controlled device to the data receiving end.
The first encoded data is encoded data obtained by encoding a target field name, that is, data obtained by encoding a target field name with a non-target field name.
The non-target field name is a field shorter than the data length of the target field name. For example, if the target field name is "device Id", the target field name is encoded by using a non-target field name 1 or a with a shorter data length, and the encoding result is as follows:
"device Id" → "a" or "1".
Illustratively, the data sending end encodes the target field name in the data to be transmitted by using a non-target field name, and then encodes the target field name in the data to be transmitted into first encoded data. It can be understood that since the target field name is encoded with a non-target field name shorter than the data length of the target field name, the length of the first encoded data is smaller than the length of the target field name.
The target field value is a device attribute value in the target device attribute data, i.e. a field value corresponding to the target field name. The target field value is used to characterize the device status information of the controlled device, i.e. the device status information of the controlled device can be known through the target field value. The object field values that appear more frequently are the commonly used object field values.
The second encoded data is encoded data obtained by encoding a frequently used target field value, that is, encoded data obtained by encoding a frequently used target field value with a non-target field value.
It should be noted that the target field value changes with the change of the operating status of the device, so the types of the target field values are more, and only the commonly used target field values are encoded in order to reduce the space required for storing the correspondence between the second encoded data and the target field values.
A non-target field value refers to a field that is shorter in data length than a common target field value. For example, if the frequently used target field value is "dff6f2f0cb2d4005a6cd98882f6c6e", the frequently used target field value is encoded by using the non-target field value 2 or b with shorter data length, and the encoding result is as follows:
"dff6f2f0cb2d4005a6cd98882f6c6e" → "b" or "2".
Illustratively, the data sending end encodes a common target field value in the data to be transmitted with a non-target field value, and then encodes the common target field value in the data to be transmitted as second encoded data. It is understood that since the common target field value is encoded with a non-target field value shorter than the data length of the common target field value, the length of the second encoded data is smaller than that of the common target field value.
It should be noted that, in order to ensure that the correspondence between the first encoded data and the target field name is unique, and in order to ensure that the correspondence between the second encoded data and the common target field value is unique, both the non-target field value and the non-target field name need to be unique.
The target data is data obtained by further compressing the data to be transmitted after the encoding processing, namely the data to be transmitted after the compression.
It should be noted that the data to be transmitted includes, in addition to the target field name and the common target field value, other field names and field values, so that after the target field name and the common target field value are encoded to obtain encoded data to be transmitted, the other field names and field values that are not encoded and the encoded data to be transmitted in the data to be transmitted are compressed to obtain the target data.
The opposite-end communication object is a communication object of the target data sent by the data sending end, namely the data receiving end. The peer communication object includes, but is not limited to, at least one of a server and an intelligent gateway.
Illustratively, the data sending end firstly encodes a target field name and a common target field value in data to be transmitted to obtain first encoded data and second encoded data. Further, the data sending end compresses the first encoding data, the second encoding data, the field names and the field values which are not subjected to encoding processing, and obtains target data. After the target data is obtained, the data sending end sends the target data to an opposite-end communication object (namely, a data receiving end).
According to the data transmission method applied to the intelligent home system, the target field names and the common target field values in the data to be transmitted are encoded by using shorter encoding data to obtain encoded data with shorter data length, and then the encoded data and the field names and field values which are not encoded in the rest of the data to be transmitted are compressed to obtain the target data with smaller data volume.
In some embodiments, the data to be transmitted includes target device attribute data and non-device attribute data; the target equipment attribute data is related attribute data of controlled equipment in the intelligent home system; the target field name is the device attribute name in the target device attribute data; the common target field value is a common device attribute value in the target device attribute data; compressing the data to be transmitted after the coding processing to obtain target data, wherein the steps specifically comprise: and compressing the non-device attribute data and the target device attribute data after the coding processing to obtain the target data.
The target equipment attribute data is related attribute data of controlled equipment in the intelligent home system and is used for representing equipment attribute data of the controlled equipment. The target device attribute data includes at least one of a target field name and a target field value. The non-relevant attribute data of the controlled equipment in the intelligent home system is the non-equipment attribute data.
Illustratively, the data sending end performs encoding processing on a target field name in target device attribute data in the data to be transmitted to obtain first encoded data, and performs encoding processing on a common target field value in the target device attribute data in the data to be transmitted to obtain second encoded data. Further, the non-device attribute data, the encoded target device attribute data (i.e. the first encoded data and the second encoded data) and the value of the unused field in the target device attribute data are all compressed by a compression algorithm to obtain the target data.
In some embodiments, the compression algorithm employed is a lossless compression algorithm, including but not limited to at least one of a Huffman algorithm and an LZW (Lenpel-Ziv & Welch) compression algorithm.
In this embodiment, a compression algorithm is used to compress the target device attribute data and the non-target device attribute data to obtain target data. Compared with the traditional data transmission method, the data transmitting end and the data receiving end have the advantages that the type of the compression algorithm adopted by the compression target data is determined in advance, and the type of the compression algorithm used when the target data is transmitted is not required to be recorded in the data header of the target data, so that the target data header resource is saved. And the target equipment attribute data and the non-target equipment attribute data are compressed by using a compression algorithm, so that the data volume of the target data is smaller, the data transmission volume is reduced, the system resource for sending the data is saved, the data transmission time is shortened, and the data transmission efficiency is further improved.
In some embodiments, the data to be transmitted is transmitted based on a communication protocol; encoding a target field name in data to be transmitted into first encoded data, wherein the steps specifically comprise: determining a protocol mapping table; the protocol mapping table comprises a first corresponding relation between the device attribute name and the first coded data and a second corresponding relation between the common device attribute value and the second coded data; based on the first corresponding relation, encoding the target field name in the data to be transmitted into corresponding first encoded data; encoding a common target field value in data to be transmitted into second encoded data, wherein the encoding method specifically comprises the following steps: and coding the common target field value in the data to be transmitted into corresponding second coded data based on the second corresponding relation.
The protocol mapping table is a container for storing a first corresponding relation between the device attribute name and the first coded data and a second corresponding relation between the common device attribute value and the second coded data.
The first corresponding relation is the corresponding relation between the device attribute name and the first coded data, and the first coded data can be restored to the device attribute name through the first corresponding relation. The second corresponding relation is the corresponding relation between the common device attribute value and the second coded data, and the second coded data can be restored into the common device attribute value through the second corresponding relation.
Exemplarily, after the data sending end generates the data to be transmitted, the target field name in the data to be transmitted is encoded into corresponding first encoded data according to the first corresponding relation; and according to the second corresponding relation, encoding the common target field value in the data to be transmitted into second encoded data.
In the embodiment, the target field names and the common target field values in the data to be transmitted are encoded based on the first corresponding relation and the second corresponding relation, and the encoding method is simple and efficient.
In some embodiments, the step of determining the protocol mapping table specifically includes: obtaining equipment attribute data corresponding to each controlled equipment according to the equipment type of the controlled equipment accessed into the intelligent home system; and establishing a corresponding relation between the same equipment attribute name and the same first coded data in the equipment attribute data, and establishing a corresponding relation between the same common equipment attribute value and the same second coded data in the equipment attribute data to obtain a protocol mapping table.
The device types are used for distinguishing the difference of the devices in terms of usage, use environment, principle and the like. For example, when the target controlled device is a smart home device, the device types are classified into an air conditioner, a refrigerator, a washing machine, a motorized window shade, a bath heater, a lighting fixture, a water heater, a fan, or the like.
The device attribute data is attribute data of a controlled device corresponding to the device type. That is, the device attribute data for the same device type are the same.
Illustratively, before sending data to be transmitted, a data sending end obtains a device type of a controlled device accessing an intelligent home system, that is, a device type of a controlled device accessing an intelligent gateway. And obtaining equipment attribute data corresponding to each controlled equipment according to the equipment type of the controlled equipment accessed into the intelligent home system. And establishing a corresponding relation between the same equipment attribute name in the equipment attribute data of each controlled equipment and the same first coded data, and establishing a corresponding relation between the same common equipment attribute value in the equipment attribute data of each controlled equipment and the same second coded data to obtain a protocol mapping table.
It can be understood that, for the controlled devices accessing the intelligent gateway of the same home, the device attribute data of the controlled devices are the same when the device types of the controlled devices are the same.
In the above embodiment, the device attribute data is determined by determining the device type of each controlled device accessing the smart home system, and the protocol mapping table is determined according to the correspondence between the device attribute data and the encoded data, so that the obtained protocol mapping table is more reasonable.
In some embodiments, before establishing a correspondence between the same common device attribute value in the device attribute data and the same second encoded data, the method further includes: acquiring historical transmission data transmitted to an opposite-end communication object in the intelligent home system; the historical transmission data comprises device historical attribute values; determining the occurrence times of the historical attribute values of the equipment in the historical transmission data; and if the occurrence times are larger than a preset threshold value, determining the historical attribute value of the equipment as the attribute value of the frequently-used equipment.
The historical transmission data is transmitted to an opposite-end communication object in the intelligent home system by the data transmitting end. It is understood that the historical transmission data includes historical device attribute data of each device, i.e., includes device historical attribute values.
The preset threshold is the number of times a preset device history attribute value appears. And determining whether the historical attribute value of the equipment is a common equipment attribute value or not through a preset threshold value.
Illustratively, a data sending end acquires historical transmission data transmitted to an opposite-end communication object in an intelligent home system, determines a device historical attribute value from the historical transmission data, and determines whether the device historical attribute value is a frequently-used device attribute value according to the occurrence frequency of the device historical attribute value in the historical transmission data; and if the occurrence times are larger than a preset threshold value, determining the historical attribute value of the equipment as the attribute value of the frequently-used equipment.
In some embodiments, if the number of occurrences of the device history attribute value is less than or equal to a preset threshold, it is determined that the device history attribute value is not a commonly used device attribute value.
In the embodiment, the attribute value of the common equipment is determined through the occurrence frequency of the historical attribute value of the equipment in the historical transmission data, and the method is convenient and simple.
In some embodiments, the device type of a new controlled device is determined when the new controlled device is accessed to the smart home system; and if the equipment type of the new controlled equipment is different from the equipment type of the previously accessed controlled equipment, updating the protocol mapping table based on the equipment attribute data of the new controlled equipment.
The new controlled equipment refers to controlled equipment which is accessed into the intelligent home system for the first time.

Further, under the condition that new controlled equipment is accessed into the intelligent home system, the data sending end determines the equipment type of the new controlled equipment; and if the equipment type of the new controlled equipment is different from the equipment type of the previously accessed controlled equipment, updating the protocol mapping table based on the equipment attribute data of the new controlled equipment.
4. Based on the first corresponding relation, the data sending end codes the target field names in the data to be transmitted into corresponding first coded data; and coding the common target field value in the data to be transmitted into corresponding second coded data based on the second corresponding relation. Wherein the target field name is a device attribute name in the target device attribute data; the common target field value is a common device attribute value in the target device attribute data.
5. And the data sending end compresses the non-equipment attribute data and the encoded target equipment attribute data to obtain target data. The target data is data to be transmitted to an opposite-end communication object in the intelligent home system.
According to the data transmission method applied to the intelligent home system, the target field names and the common target field values in the data to be transmitted are encoded by using shorter encoding data to obtain encoded data with shorter data length, and then the encoded data and the field names and field values which are not encoded in the rest of the data to be transmitted are compressed to obtain the target data with smaller data volume.
