< method example >
Fig. 1 shows a flowchart of a data transmission method of an internet of things device according to an embodiment of the present disclosure. As shown in fig. 1, the method includes steps S1100-S1400.
S1100, acquiring the capability state of the output device.
In the application scenario of the internet of things, if the internet of things device a can control the internet of things device B, the internet of things device a is an output device, and the internet of things device B is an input device. For example, the door and window sensor may detect a door and window open/close state, and if the door and window sensor detects that the door and window is in an open state, the door and window sensor will control the floor fan to be closed; when the door and window sensor detects that the door and window is in a closed state, the floor fan is controlled to be opened; the door and window sensor can control the switch state of the floor fan, and the door and window sensor is output equipment, and the floor fan is input equipment.
Device capabilities are functions that the device has. For example, a home light has a switching capability, a brightness capability, and a color temperature capability, and then the home light switching function, the brightness adjustment function, and the color temperature adjustment function are characterized.
The capability status of a device is the functional status of the device. For example, a home light switching capability may have two capability states, on and off, a brightness capability may have three capability states, high, medium, and low, and a color temperature adjustment capability may have three capability states, warm, neutral, and cool.
In this embodiment, the output device and the input device are respectively connected to the cloud platform in a communication manner, and the cloud platform executes the data transmission method of this embodiment, so as to implement data interaction between the output device and the input device.
In one possible implementation, the cloud platform may obtain the capability status of the output device in an active manner. Specifically, the cloud platform may issue an instruction for querying the device state to the output device, so as to detect the capability state of the current output device through the instruction, and further obtain the capability state of the current output device.
In another possible implementation manner, when the capability state of the output device changes, the current capability state is reported to the cloud platform, so that the cloud platform can acquire the capability state of the output device.
S1200, acquiring a data packet matched with the capability state, wherein the data packet comprises at least two preset data types and data values corresponding to the data types.
In one possible implementation manner, when acquiring the data packet matched with the capability state of the output device, the data packet may be implemented based on a first mapping relation table configured in advance, where the first mapping relation table includes multiple types of internet of things devices, multiple types of device capabilities are configured for each type of internet of things device, multiple types of capability states are configured for each type of device capability, and data packets matched with each type of capability state are configured for each type of capability state, so that after acquiring the capability state of the output device, the data packet matched with the capability state of the output device may be acquired by querying the first mapping relation table.
It should be noted that, the multiple device capabilities configured for each type of internet of things device in the first mapping table covers the capabilities of all the same type of internet of things devices in the market. For example, some home lamps in the market only have the capability of switching, some home lamps have the capability of switching and brightness adjustment, and some home lamps have the capability of switching, brightness adjustment and color temperature condition at the same time, so the device capability configured for the internet of things devices such as the home lamps in the first mapping relation table comprises the capability of switching, brightness and color temperature.
Further, the plurality of capability states configured for each device capability in the first mapping table covers all capability states that the capability may have on the market. For example, if the brightness capability of some home lamps on the market has only one capability state, the brightness capability of other home lamps has two capability states of high capability and low capability states, and the brightness capability of other home lamps has three capability states of high capability state, medium capability state and low capability state, the first mapping relation table is configured with the three capability states of high capability state, medium capability state and low capability state for the brightness capability of the home lamps.
Further, the first mapping relation table is configured with data packets matched with each capability state, that is to say, the first mapping relation table can query data packets corresponding to various capability states of various kinds of Internet of things equipment in the adaptation market, so that the universal usability of the data transmission method is ensured.
In one possible implementation, the predetermined data type in each data packet may include at least one of a boolean type, an integer type, a character type, a floating point type, and an enumeration type. Specifically, the boolean type data type may be denoted as pool, the integer type data type may be denoted as int, the character type data type may be denoted as string, the floating point type data type may be denoted as float, the enumeration type data type may be denoted as enum, based on which the content of the packet may be as shown in table 1.
In one possible implementation manner, the data value corresponding to each data type in the data packet is determined based on the usual control requirement of the user, so that the control of the internet of things device can meet the usual control requirement of the user, and the use experience of the user is improved.
For example, a user may generally expect that a door and window is opened, and may control an indoor floor fan to be closed, where the floor fan has a wind speed of 0, and the working mode is selected to be closed, and the monitoring device may display a "door and window opening" word, and simultaneously expect that the door and window is closed, and may control the indoor floor fan to be opened, and operate at a wind speed 60 with a most comfortable body feeling, and operate with an automatic working model, and the monitoring device may display a "door and window closing" word, where the floor fan is opened typically using a bool type data control, the wind speed is typically using an int type data control, the working model is typically using an enum type data control, the monitoring device display word is typically using a string type data control, and at this time, a data packet of a closed capacity state of a door and window sensor opening capacity may be set in a form of table 1, and a data packet of a separated capacity state of a door and window sensor opening capacity may be set in a form of table 2.
TABLE 1
TABLE 2
S1300, acquiring the receivable data type of the input device, and generating a control instruction of the input device based on the data packet, the receivable data type and the capability of the input device.
In one possible implementation, the receivable data type of the input device is determined based on the capabilities of the input device to be controlled. Specifically, in the first mapping relationship table, for each capability of each type of the internet of things device, a data type that can be supported by a corresponding capability interface is recorded, so that when determining the capability of the input device to be controlled, the data type that can be supported by the capability interface corresponding to the capability of the input device to be controlled can be queried by querying the first mapping relationship table, and the data type is taken as the receivable data type of the input device.
For example, the output device is a door and window sensor, the input device is a floor fan, the switching capacity of the floor fan needs to be controlled by the switching capacity of the door and window sensor, and at this time, in the first mapping table, the data type that can be supported by the capacity interface corresponding to the switching capacity of the floor fan is queried to be a bool type, and the bool type is used as the data type that can be received by the floor fan switching capacity interface.
In one possible implementation, when generating the control instruction of the input device based on the data packet, the receivable data type and the capability of the input device, the method may include the steps of: first, a data value corresponding to a receivable data type is extracted from a data packet. Second, a control instruction template is obtained that controls the capabilities of the input device. And finally, filling the data value corresponding to the receivable data type into a preset position of the control instruction template to obtain the control instruction of the input device.
In a possible implementation manner, when the control instruction template for controlling the capability of the input device is obtained, the control instruction template may be implemented based on a second mapping relation table configured in advance, where the second mapping relation table includes multiple types of internet of things devices, multiple types of device capabilities are configured for each type of internet of things device, and a control instruction template matched with each type of device capability is configured for each type of device capability, so that after the capability of the input device is obtained, the control instruction template matched with the capability of the input device is obtained by querying the second mapping relation table.
Further, the control instruction template includes the capability control parameters to be assigned, so that after the control instruction template for controlling the capability of the input device is obtained, the data value corresponding to the receivable data type can be filled in the capability control parameters to be assigned, so as to obtain the control instruction of the input device.
S1400, sending the control instruction to the input device.

In one possible implementation, the data transmission method of the present disclosure is implemented based on a data transmission application, wherein the data transmission application is generated based on an imaging internet of things application development tool.
In one possible implementation, the development interface of the graphical development tool may be as shown in FIG. 2. Specifically, the graphical development interface may at least include a device library, a logical list, and an application editing area of the internet of things. The device identification of the plurality of types of internet of things devices is configured in the device library, and based on the device identification, the corresponding internet of things devices can be rendered in the internet of things application editing area. A plurality of visualized logical block identifications are configured in the logical list, and based on the logical block identifications, corresponding data processing logic can be created in the application editing area of the internet of things.
In one possible implementation manner, when the imaging-based internet of things application development tool generates a data transmission application program, the method may include the following steps:
first, according to the triggering of the device identifiers corresponding to the output device and the input device, the output device block and the input device block are rendered in the application editing area of the Internet of things.
For example, the equipment library may include equipment identifiers of various internet of things equipment such as door and window sensor identifiers, floor fan identifiers, ceiling fan lamp identifiers and the like. When a user needs to generate a data transmission application capable of controlling the opening and closing capability of the floor fan through the opening and closing capability of the door and window sensor, a window sensor identifier can be selected from the equipment library and dragged to an application editing area of the internet of things so as to render a door and window sensor block shown in fig. 3. And selecting a floor fan mark, and dragging the floor fan mark to an application editing area of the Internet of things to render a floor fan block shown in fig. 3.
Second, an output capability interface is created on the output device tile according to the configured output device capabilities.
In one possible implementation, when an output capability interface is created on an output device tile, a control implementation may be created based on the capability interface on the device tile.
Specifically, a device block rendered by the application development tool of the internet of things based on the imaging is provided with an [ + ] button (i.e. a capability interface creation control) as shown in fig. 3, wherein the [ + ] button (i.e. an input capability interface creation control) positioned on the left side of the device block is used for creating an input capability interface, and the [ + ] button (i.e. an output capability interface creation control) positioned on the right side of the device block is used for creating an output capability interface.
In one possible implementation manner, for each internet of things device in the device library, a corresponding device capability list is provided, where the device capability list includes at least two capabilities of the device. The device list may be a set of capabilities that all of the same type of devices on the market have. For example, if some home lamps in the market have only switching capability, some home lamps have both switching capability and brightness adjusting capability, and some home lamps have both switching capability, brightness adjusting capability and color temperature condition capability, the capability list of the home lamps may include switching capability, brightness capability and color temperature capability. Further, custom capability can be set in the capability list, and the device capability can be newly added according to a specific application scene through triggering of the custom capability.
Further, a first mapping relation between various device identifiers and corresponding capability lists is stored in the system, so that when a capability interface creation control on a device image block is triggered, the triggered device identifiers are acquired, the capability list corresponding to the device identifiers is acquired by inquiring the first mapping relation, the acquired capability list is pushed and displayed to a position adjacent to the currently triggered capability interface creation control, and therefore a user can select target capability to be configured in the pushed and displayed capability list, and the system further displays the selected target capability on the triggered capability interface creation control so as to complete creation of the corresponding capability interface.
In the above embodiment, the user needs to create an output capability interface for the window sensor tile, where the output capability interface is used to transmit the open state of the door and window, at this time, the user may trigger the [ + ] button located on the right side of the window sensor tile, at this time, the capability list of the window sensor will be displayed at the adjacent position of the triggered [ + ] button, the user selects the door and window status capability in the capability list of the window sensor, at this time, the system will display the door and window status word on the currently triggered [ + ] button, and the creation of the door and window status output capability interface of the window sensor tile is completed, and the creation result is specifically see 3.
Third, an input capability interface is created on the input device tile according to the configured input device capabilities.
In the above embodiment, the user needs to create an input capability interface for a floor fan block, where the input capability interface is used to control the on state of the floor fan, and at this time, the user may trigger the [ + ] button located on the left side of the floor fan block, at this time, the capability list of the floor fan will be displayed at the adjacent position of the triggered [ + ] button, the user selects the switch capability in the capability list of the floor fan, at this time, the system will display the switch word on the currently triggered [ + ] button, so as to complete the creation of the input capability interface of the floor fan, and the creation result is specifically see fig. 3.
Fourth, according to the connection trigger of the output capability interface and the input capability interface, a connection line of the output capability interface and the input capability interface is established, so as to obtain a device topological diagram of the output device and the input device.
In the embodiment, the user clicks the door and window state output capability interface and the input capability interface of the floor fan on the window sensor block in sequence, and at this time, a connection line is established between the two capability interfaces, so that the construction of the device topology diagram of the window sensor and the floor fan is completed.
Fifth, a data transfer application is generated based on the device topology.
In one possible implementation, when generating a data transmission application based on a device topology graph, the method may include the steps of:
first, output device tile information and output capability interface information are obtained, and output devices and capabilities of the output devices are determined.
Second, based on the output device and the capability of the output device, generating a first code for acquiring the capability state of the output device, and a second code for acquiring a data packet matched with the capability state of the device;
thirdly, acquiring block information and input capability interface information of the input equipment, and determining the capabilities of the input equipment and the input equipment;
fourth, based on the input device and the capability of the input device, generating a third code for acquiring the receivable data type of the input device, and based on the data packet, the receivable data type and the capability of the input device, generating a control instruction of the input device;
fifth, generating a fourth code for transmitting the control instruction to the input device;
sixth, the first code, the second code, the third code and the fourth code are combined in sequence to obtain the data transmission application program.
In one possible implementation manner, after the data transmission application program is generated, the user can be supported to query the data packet matched with the capability state of the output device, so that whether the data value in the default matched data packet meets the current control requirement can be judged, if the data value does not meet the control requirement, a logic editing area can be built on the capability interface connection line of the device topological graph, and the data value in the default data packet can be modified through a visual logic block arranged in the logic editing area.
For example, in an embodiment of controlling the air speed of the floor fan through the door and window states of the door and window sensors, a door and window sensor block and a floor fan block as shown in fig. 4 are respectively rendered in an application editing area of the internet of things, a door and window state capability interface is set for the door and window sensor block, and an air speed capability interface is set for the floor fan block; and then establishing a connecting line between the door and window state capability interface of the door and window sensor block and the wind speed capability interface of the floor fan block. Because the imaging development tool sets a default data packet matched with each internet of things device in the device library according to the state of each capability in the capability list in addition to the corresponding capability list, after the device topology diagram is generated by connecting lines, a first default data packet (such as table 2) corresponding to the closed state of the door and window sensor and a second default data packet (such as table 1) corresponding to the separated state can be queried, the operation at the wind speed 60 of the floor fan can be controlled when the door and window state of the window sensor is closed by the first default data packet, and the operation at the wind speed 0 of the floor fan can be controlled when the door and window state of the window sensor is separated by the second default data packet. If the control of the floor fan to operate at the wind speed 80 is to be realized when the door and window state of the door and window sensor is closed at this time, a logic editing area as shown in fig. 4 can be established at the midpoint of the connection by clicking the midpoint of the connection, an input interface connected with a door and window state capability interface on the logic editing area is configured as A1, and an output interface connected with the wind speed capability interface is configured as B1. Further, by setting the modification logic as shown in fig. 4 in the logic edit area through the visualization logic block, the data value in the first default data packet can be modified from 60 to 80 through the above modification logic.
The data transmission method of the Internet of things equipment comprises the steps of obtaining the capability state of output equipment; acquiring a data packet matched with the capability state, wherein the data packet comprises at least two preset data types and data values corresponding to the data types; acquiring a receivable data type of the input device, and generating a control instruction of the input device based on the data packet, the receivable data type and the capability of the input device; and sending the control instruction to the input device. Because the data packet of the output device comprises data values corresponding to various types of data, the input device can select the corresponding data values to process according to the data types supported by the input device under the condition of receiving the data packet, so that data transmission among the devices supporting different data types of the Internet of things can be realized. That is, communication compatibility between the incompatible devices is achieved in the present disclosure by data packets structured with custom data types.
