In the home system of the internet of things, many physical devices are involved, such as lighting fixtures, curtains, air conditioners, televisions and the like. In the related art, in a scene where multiple devices need to be used simultaneously, the multiple devices in the same scene are from different manufacturers, and multiple control terminals or control programs are needed for control. For example, physical devices in a living room need to be controlled by one control terminal, physical devices in a kitchen (such as a dishwasher, a refrigerator and the like) need to be controlled by another control terminal, and physical devices in a bedroom (such as an air conditioner, a humidifier, a dehumidifier and the like) need to be controlled by another control terminal. Therefore, the convenience of the user is not high when the user uses the internet of things home system in the related technology; the cost of the equipment is high due to the fact that the number of the used control terminals is large, and the control program of each control terminal is complex; due to the fact that the number of the control terminals is large, the difficulty degree of maintaining the home system of the Internet of things is improved.
In addition, the applicable protocols of various entity devices related to the internet of things home system are various, in the related technology, the communication among the entity devices with different protocols is incompatible, and the traditional entity devices with different protocols realize communication in a pairwise mutual conversion mode, so that the types and the number of required protocol conversion devices are large, and the cost is high; moreover, the related art cannot realize mutual communication between two or more entity devices.
In order to solve the above problems, an access fusion control method for internet of things devices is provided in the embodiments of the present application, which is characterized in that a uniform abstraction method is adopted to abstract entity devices in an intelligent home system into shadow devices on one control terminal (i.e., an internet of things cloud platform), and control over all the entity devices can be realized by using the one control terminal, so that the control terminals of all the entity devices in the intelligent home system are concentrated on the same control terminal, thereby reducing the cost required by devices, reducing the difficulty of controlling control programs of the entity devices, and reducing the difficulty of maintaining the internet of things home system. Meanwhile, the intelligent gateway equipment capable of converting different protocols is applied, so that the cost is reduced, and the mutual communication between more than two kinds of entity equipment is realized; the Internet of things cloud platform can realize communication with entity devices of various different protocols through the intelligent gateway device, and the structure and the communication interaction node of the intelligent home system are simplified.
An internet of things device access fusion control method is applied to an internet of things system, as shown in fig. 1, the internet of things system comprises an intelligent device module, an intelligent gateway module, an internet of things cloud platform and a third application platform (the third application platform can be a mobile phone APP, a tablet computer APP or other control terminals capable of generating related control signals), the intelligent device module is in communication connection with the intelligent gateway module, the intelligent gateway module is in communication connection with the internet of things cloud platform, and the internet of things cloud platform and the intelligent gateway module are in communication connection with the third application platform respectively.

The IOT cloud platform abstracts entity equipment into shadow equipment.
The intelligent gateway module is in communication connection with the intelligent equipment module, and the entity equipment in the intelligent equipment module reports the entity equipment information of the entity equipment to the intelligent gateway module. The entity device information may specifically include a device ID, a space (e.g., bedroom, kitchen, living room, bathroom, etc.), a device type, a manufacturer, and other basic information of the entity device. The intelligent gateway module counts and collects entity equipment in an intelligent home system, the intelligent gateway module uploads the acquired entity equipment information to an Internet of things cloud platform, and the Internet of things cloud platform receives a plurality of entity equipment information uploaded by the intelligent gateway module; the entity equipment in the intelligent home system can be better controlled conveniently in the follow-up process.
A product management module (SDF module) in the internet of things cloud platform abstracts the plurality of entity devices into a plurality of shadow devices according to the information of the plurality of entity devices, and specifically abstracts the characteristics and functions of the entity devices into attributes, capabilities, and events of the shadow devices.

The embodiment of the application adopts a uniform abstraction method, the entity devices in the intelligent home system are abstracted into the shadow devices on one control terminal (namely, the thing networking cloud platform), and the control of all the entity devices can be realized by using the control terminal, so that the control terminals of all the entity devices in the intelligent home system are centralized to the same control terminal, the cost required by the devices is reduced, the difficulty of controlling the control programs of the entity devices is reduced, and the difficulty of maintaining the thing networking home system is also reduced.
The Internet of things cloud platform creates a scheme shadow; the solution shadow includes a plurality of shadow devices.
The product scheme refers to the entire smart home control system in a living room, for example, as shown in fig. 2, a unit 101 in a building 1 includes two spaces, namely a guest dining room and a kitchen.
The dining room comprises four physical devices, namely a three-key switch, a living room ceiling lamp, an atmosphere lamp and a dining room lamp. The three-key switch can control the on-off states of the ceiling lamp, the atmosphere lamp and the dining hall lamp. The kitchen includes two devices, a kitchen light and a single key switch. The single key switch is used for controlling the kitchen lamp. Wherein sitting room dome lamp, atmosphere lamp, dining room lamp and kitchen lamp are connected with the light controller, and the light controller passes through Modbus and intelligent gateway module wired connection, and three key switch and single key switch pass through EnOcean and intelligent gateway module wireless connection.
For example, in step 1, the intelligent gateway module receives entity equipment information uploaded by a three-key switch, a living room ceiling lamp, an atmosphere lamp, a dining room lamp, a kitchen lamp and a single-key switch, and forwards the entity equipment information to the internet of things cloud platform; a product management module (SDF module) of the IOT cloud platform abstracts all entity devices as shadow devices.
The living room ceiling lamp is characterized by being located in a space of a living room, and has the functions of turning on and off the lamp, abstracting the living room ceiling lamp as a shadow device, namely the living room ceiling lamp, and having the attribute of being in an on-off state.
The atmosphere lamp is characterized by being located in a space of a guest restaurant, the functions of the atmosphere lamp are turning on and off, the atmosphere lamp is abstracted to be a shadow device, namely the atmosphere lamp, and the attribute of the atmosphere lamp is in an on-off state.
The dining room lamp is characterized by being in a space of a guest dining room, the function of the dining room lamp is to turn on and off the lamp, the dining room lamp is abstracted into a shadow device, namely the dining room lamp, and the attribute of the dining room lamp is in an on-off state.
The three-key switch is characterized by being located in the space of a guest restaurant, has the functions of turning on a light and turning off the light, is abstracted into a shadow device, namely, the three-key switch, has the attribute of performing switching action, and has the capability of switching on and off a ceiling light, an atmosphere light and a dining room light in the guest restaurant.
The kitchen lamp is characterized by being located in a kitchen space, the function of the kitchen lamp is to turn on and off the lamp, the kitchen lamp is abstracted to be a shadow device, namely the kitchen lamp, and the attribute of the kitchen lamp is an on-off state.
The single-key switch is characterized by being located in a kitchen space, has the functions of turning on and turning off the light, is abstracted into a shadow device, namely, the single-key switch, and has the attribute of performing switching action.
For example, in step 2, a scheme shadow management module in the internet of things cloud platform extracts a plurality of shadow devices corresponding to a plurality of entity devices required in the product scheme according to the requirement of the product scheme, and constructs a scheme shadow.
That is, the product scenario corresponds to a scenario shadow, which is a virtual scenario existing in the control terminal of the product scenario. The solution shadow includes the shadow device corresponding to the entity device required by the product solution, i.e. the mapping relation between the solution shadow and the shadow device is constructed.
After the solution shadow management module creates the solution shadow, a corresponding solution shadow interface can be generated to be called by a solution shadow query interface in the service interface module. When the third-party application platform needs to query the corresponding scheme shadow, the query can be carried out by calling a scheme shadow query interface.
After the scheme shadow is created, for the entity device required by the product scheme and the shadow device in the scheme shadow, the method for controlling the access fusion of the internet of things device is applied, as shown in fig. 3, and specifically comprises the following steps:
step S300, the intelligent gateway module builds the device shadow of each entity device according to different protocols and corresponding entity device networking.
The equipment shadow module in the intelligent gateway module establishes an equipment shadow according to different protocols and corresponding entity equipment networking; and uploading the device shadow to a device shadow management module of the internet of things cloud platform. The device shadow, the entity device and the shadow device are in one-to-one correspondence.
The device shadow is a data set used for storing the reported state of the device and the expected state information of the application program. In order to control the entity device, the embodiment of the application needs to know the working state of the entity device. When the user knows that the ceiling lamp in the living room is turned off, the basis for controlling the ceiling lamp in the living room to be turned on is available, and if the user does not know whether the ceiling lamp in the living room is turned on or off, the user cannot control the ceiling lamp in the living room effectively.
For example, in the unit 101 room of building 1, No. 1, the intelligent gateway module establishes an equipment shadow of the light controller according to the Modbus and light controller networking. The intelligent gateway module respectively networks with the three-key switch and the single-key switch through EnOcean, respectively establishes equipment shadows of the three-key switch and the single-key switch, and uploads the equipment shadows to the IOT cloud platform; and the living room ceiling lamp, the atmosphere lamp, the dining room lamp and the kitchen lamp are networked with the intelligent gateway module according to a specific protocol, an equipment shadow is established, and the equipment shadow is uploaded to the Internet of things cloud platform.
Step S301, the intelligent gateway module receives a status signal reported by the entity device, and sends the status signal to the internet of things cloud platform.
The entity equipment reports the state signals containing the working states of the entity equipment to the intelligent gateway module, and then forwards the state signals to the Internet of things cloud platform through the intelligent gateway module. The condition for reporting the working state of the entity device can be reporting at regular time or reporting when the state of the entity device changes.
For example, if the state of the ceiling lamp in the living room is off, the ceiling lamp in the living room reports the state of the ceiling lamp to the intelligent gateway module through the state signal.
Step S302, the IOT cloud platform analyzes the working state contained in the state signal and stores the working state into the equipment shadow of the IOT cloud platform.
And the equipment reporting information analysis module of the IOT cloud platform analyzes the working state contained in the state signal, stores the working state into the equipment shadow, and stores the equipment shadow into the equipment shadow management module.
For example, the device reported information analysis module analyzes the device ID and the operating status contained in the status signal, and stores the device ID and the operating status into the device shadow.
Step S303, the Internet of things cloud platform receives a control signal.
The control signal in the embodiment of the present application can be obtained in two ways:
in the first mode, an Internet of things cloud platform receives a control signal sent by an intelligent gateway module; the control signal of the intelligent gateway module is from a third-party application platform;
in the second mode, the internet of things cloud platform receives the control signal sent by the third-party application.
The difference between the two modes is that the first mode is that the third-party application platform sends a control signal to the internet of things cloud platform through the intelligent gateway module, and belongs to a local control mode, namely under the condition that the internet does not exist, the third-party application platform sends the control signal to the intelligent gateway module through the Web socket, and the intelligent gateway module sends the control signal to the internet of things cloud platform through the MQTT. The second mode is that a third-party application platform directly sends a control signal to the Internet of things cloud platform, belongs to a remote control mode, and sends the control signal to the Internet of things cloud platform through the Internet. Specifically, the internet of things cloud platform receives a control signal through a control device interface.
The control signal is generated as follows:
step S400, the Internet of things cloud platform binds entity devices corresponding to the plurality of shadow devices in the scheme shadow with corresponding device shadows, and constructs a function state list of the entity devices.
The shadow devices correspond to the device shadows in a one-to-one manner, the shadow devices are virtual devices of the physical devices on the internet of things cloud platform, and the device shadows store the working state or the expected state of the shadow devices (or the physical devices). The shadow device is bound to the device shadow, thereby building a list of functional states.
When the third-party application platform needs to check the state of the entity equipment in the intelligent home system, the working state of the current entity equipment can be quickly acquired by calling a scheme shadow query interface of the internet of things cloud platform and checking a function state list.
Step S401, a third party application platform acquires the function state list and generates the control signal according to the function state list.
After the user inquires the function state list through the third-party application platform, the working state of the corresponding entity device can be adjusted according to own will, namely the user inputs requirements, and the third-party application platform generates corresponding control signals according to the requirements.
And the control signal enters the Internet of things cloud platform through a control equipment interface of the Internet of things cloud platform.
For example, if the user checks that the working state of the ceiling light in the living room is off, and wants to turn on the ceiling light in the living room at this time, after the user triggers the third-party application platform, the third-party application platform generates a control signal containing the expected state of turning on the ceiling light in the living room.
Step S304, the internet of things cloud platform analyzes the expected state of the target entity device included in the control signal and updates the expected state to the device shadow of the corresponding entity device.
And an entity equipment control signal analysis module in the Internet of things cloud platform analyzes the control signal. The control signal includes the device ID and the expected state of the target entity device that the user needs to control, and the expected state is stored in the device shadow according to the device ID.
For example, the entity device control signal analysis module analyzes the device ID and the expected state of the hall ceiling lamp in the obtained control signal, and updates the expected state to the device shadow of the corresponding entity device.
Step S305, the intelligent gateway module determines whether the working state in the device shadow is the same as the expected state.
In the using process of the smart home system, a situation of false triggering may exist, for example, the state of a certain entity device includes a state a, a state B and a state C, the current working state is in the state B, and a control signal whose expected state is the state B is generated by false triggering of a user, after receiving the control signal, the entity device meets the requirement of the user without action, and at this time, if the control signal is executed according to step S106, the entity device module, the smart gateway module and the internet of things cloud platform can perform useless work, so that the smart gateway module determines whether the working state in the device shadow is the same as the expected state, thereby avoiding the useless work of the smart home system, improving the control speed and saving the device resources.
Step S306, when the working state in the device shadow is different from the expected state, the intelligent gateway module converts the control signal into a standard data format signal, and the intelligent gateway module converts the standard data format signal obtained by converting the control signal into a protocol signal applicable to the corresponding entity device and sends the protocol signal to the target entity device.
Step S306 specifically includes:
when the working state of the target entity equipment is different from the expected state, the intelligent gateway module judges whether the standard data format signal obtained by converting the control signal contains an execution action;
and if the execution action is contained, the intelligent gateway module converts the standard data format signal obtained by converting the control signal into a protocol signal applicable to the corresponding entity equipment and sends the protocol signal to the target entity equipment. Meanwhile, the intelligent gateway module uploads the standard data format signal obtained by converting the control signal to the IOT cloud platform as data in a notification format.
And if the execution action is not contained, the intelligent gateway module uploads the standard data format signal converted by the control signal to the IOT cloud platform as the data in the message format.
In another embodiment provided by the present application, a plurality of physical device linkage control modes are further provided, specifically as follows:
and S500, receiving a linkage control signal sent by a third-party application platform by the Internet of things cloud platform.
In a specific application process of the smart home system, there is usually a simultaneous control of two or more physical devices, for example, a curtain in a room should be closed and a lighting fixture in the room should be opened at the same time, that is, closing the curtain and opening the lighting fixture are a coordinated control signal.
The third-party application platform can customize entity equipment needing linkage according to a user, packages and places a trigger program of the corresponding linkage control signal in the third-party application platform, when the user needs to control one group of linkage entity equipment, triggers the third-party application platform to generate the corresponding linkage control signal, and the Internet of things cloud platform receives the linkage control signal. Seen from the user side or the third-party application platform side, the linkage control signal is adopted, so that the user can conveniently control the entity equipment, unnecessary complicated operations are reduced, and the intelligent degree of the intelligent home system is improved.
