FIG. 1A is a schematic diagram of a user interface of a control device according to an embodiment of the present application.

In some embodiments, the control device provided by the present application may include a display, and the display may display a user interface, and the user interface may display a terminal device controllable by the control device, and perform control and status display on the terminal device through the user interface.

As shown in fig. 1A, application icons for controlling the range hood and the refrigerator are displayed in the control device user interface, and a user can enter the equipment control user interface by clicking the corresponding application icon.

The control device also comprises an interface which can be connected with terminal equipment, and when the terminal equipment is implemented as a cigarette machine and a refrigerator, the terminal equipment can be respectively connected with the control device through the interface; in the following, the technical solution provided by the present application will be described by taking the interface as an example, and for convenience of description, all related serial ports are referred to by using the interface, and are not explained again.

For example, the control device is respectively connected to the smoke machine and the refrigerator through the interfaces 2 and 3 so as to realize the centralized control of the control device on the smoke machine and the refrigerator;

in some embodiments, when the interface of the control device is implemented as a serial port, the connection with the terminal device is schematically shown in fig. 2B, and the serial port may be used for accessing the terminal device, such as the serial port 1 access device 1, the serial port 2 access device 2, and the serial port 3 access device 3, respectively, as shown in fig. 2B.

FIG. 1B shows a schematic view of a user interface of a control device according to another embodiment of the present application.

In some embodiments, based on the control device user interface shown in fig. 1A and the connected terminal device, when the newly added air conditioner is connected to the control device through the interface 1, the control device may identify the newly accessed air conditioner and display an application icon corresponding to the newly accessed air conditioner on the user interface, through which the user may control the air conditioner.

In this embodiment, the range hood, the refrigerator, and the air conditioner of the terminal device may be connected to the interface in a wireless access manner to implement communication with the control device, and the wireless access manner is not specifically limited in this application.

For example, the smoke machine and the refrigerator are respectively connected to the control device through an interface 2 and an interface 3, and the interfaces are both implemented as serial ports; when the air conditioner of the newly added equipment is connected to the interface 1, a first controller of the control device immediately detects that the external equipment is connected to the interface 1;

it should be noted that, in the above detection phase in some embodiments, the first controller can only detect that a device is connected to the interface, but cannot identify the device type of the connected device.

In some embodiments, when detecting that the first device is connected to the first interface, the first controller of the control apparatus sends a generic device identification signaling to the first interface, where the generic device identification signaling includes a first field for reading a first type of the first device, and the first type is a device type of the first device.

For example, based on the control apparatus shown in fig. 1B, the newly added device air conditioner is connected to the control apparatus, and when the first controller detects that the air conditioner is connected to the first interface, a generic device identification signaling is sent to the first interface, where the generic device identification signaling includes the first field that can be implemented as a read device command field; by reading the device command field, the first controller may acquire the device type of the first device air conditioner.

It should be noted that the generic device identification signaling may be handled by the first device and the second device, that is, identified by different types of terminal devices.

In this embodiment, the generic device identification signaling may be identified and processed by the refrigerator, the range hood, and the air conditioner shown in fig. 1B; in other embodiments, the general device identification signaling can be further identified and processed by white appliances such as intelligent doorbells, washing machines, microwave ovens and the like.

The universal equipment identification signaling has universality, and for the accessed terminal equipment, the universal equipment identification signaling can be received, identified and processed, so that the control device can acquire the equipment type of the terminal equipment; by sending the generic device identification signaling, the connection relationship of the first device to the first interface can be determined.

After the first controller sends the general equipment identification signaling to the air conditioner, the second controller of the air conditioner receives the general equipment identification signaling containing the reading equipment command field, generates a reply signaling containing the type of the air conditioner based on the reading equipment command field, and feeds the reply signaling back to the control device through the first interface.

In some embodiments, the generic device identification signaling sent by the first controller to the first device further includes a second field and a third field, where the second field is used for the terminal device to identify its received signaling as the generic device identification signaling, and the third field is used for communication error checking to verify integrity of the signaling.

For example, when the control apparatus is powered on or a new device is connected to the interface, the first controller sends a generic device identification signaling to all the interfaces, where the generic device identification signaling may include three fields, namely, a combined protocol header field, a read device command field, and a Cyclic Redundancy Check (CRC) Check field, where the first field is the read device command field, the second field is the combined protocol header field, and the third field is the CRC Check field.

The cyclic redundancy check code is one of the most commonly used error checking codes in the field of data communication, and is characterized in that the lengths of the information field and the check field can be selected at will. The cyclic redundancy check is a data transmission error detection function, performs polynomial calculation on data, attaches the obtained result to the back of a frame, and a receiving device also executes a similar algorithm to ensure the correctness and the integrity of data transmission.

After the refrigerator equipment receives the command, the second controller of the refrigerator equipment carries out comprehensive protocol header and CRC (cyclic redundancy check) check; after the verification is passed, if the equipment receives the signaling containing the equipment reading command field, the second controller generates a reply signaling for feeding back the control device, wherein the reply signaling contains the equipment type of the refrigerator;

the control device receives the reply signaling, wherein the reply signaling comprises a comprehensive protocol header field, a device definition field and a CRC field; the first controller carries out comprehensive protocol header and CRC check on the reply signaling; after the check is passed, a device definition field is read, which contains the above-mentioned device type information of the device.

Through the second field and the third field, the accessed device can distinguish the signaling from the control device so as to distinguish the general device identification signaling and the common control signaling.

It should be noted that, in some embodiments, the terminal device, the cigarette maker, the refrigerator, and the air conditioner may be connected to the interface in a wired access manner, so as to implement communication with the control device, as shown in fig. 1C; the smoke machine and the refrigerator are respectively connected to a control device through an interface 2 and an interface 3, the air conditioner of the newly added equipment can be connected to the control device through an interface 1, and the interfaces can be implemented as serial ports; the specification and drawings do not limit the specific interface position, interface number and interface sequence for the device access.

Hereinafter, a control scheme for dynamically identifying, displaying, and controlling the accessed device based on the interface after the control device receives the reply signaling will be described.

In some embodiments, the first device accesses the first interface, and the control apparatus, after receiving the reply signaling fed back by the first device, loads a first database corresponding to the first type on the control apparatus based on the device type information included in the control apparatus, that is, based on the first type of the first device.

For example, when the new access device is an air conditioner, the first controller loads an air conditioner database according to the device type information contained in the reply signaling; correspondingly, when the new access equipment is a cigarette machine or a refrigerator, the first controller correspondingly loads a cigarette machine database or a refrigerator database; the device database is also referred to in some embodiments as a device capability library, such as an air conditioning capability library, a cigarette smoking capability library, or a refrigerator capability library.

For example, when the first database is an air conditioner database, the air conditioner database may provide a corresponding analysis service in the process of analyzing the display and control signaling related to the air conditioner by the first controller, so as to realize that the user interface displays and controls the corresponding controllable air conditioner.

In some embodiments, after the newly added device is accessed to the control device, the system in which the control device is located loads the protocol analysis service, after the reply signaling fed back by the device is obtained, the first controller controls the protocol analysis service, and loads the corresponding database according to the device type read by the reply signaling, and each database is responsible for analyzing the device accessed correspondingly.

In some embodiments, the control device controls the terminal device through different serial ports, so that the serial port communication capability in the protocol analysis service is configured independently to realize signaling transmission and reception with different databases.

In some embodiments, in the process that the control device controls the terminal device through the serial port, the protocol analysis service analyzes the control signaling sent by the control device through the corresponding database, and then sends the control signaling to the serial port communication writing module and the terminal device connected with the serial port communication writing module;

after the terminal device executes the control signaling, a response signaling corresponding to the device state information is fed back to the serial port communication reading module, the protocol analysis service analyzes the response signaling based on the corresponding database, and the device state information contained in the response signaling is displayed on a user interface of the control device.

For example, taking a serial port of an air conditioner access control device as an example, a user sends a control signaling for adjusting temperature, the protocol analysis service analyzes the control signaling through an air conditioner database of the pronunciation, the analyzed control signaling can be identified and processed by the accessed air conditioner, and the control signaling is sent to a serial port communication write-in module and is transmitted to the corresponding air conditioner through a network;

after the air conditioner implements the control signaling, a reply signaling containing equipment state information is fed back to the serial port communication reading module, the protocol analysis service analyzes the reply signaling based on the air conditioner database, so that the reply signaling can be received and processed by the control device, and the equipment state information transmitted by the air conditioner can be displayed on a user interface of the control device. The access device may also be implemented as a cigarette maker or a refrigerator, and the correspondingly loaded database may be implemented as a cigarette maker database or a refrigerator database, as shown in fig. 2C.

Fig. 2D is a schematic diagram illustrating an overall architecture of a protocol resolution service in a control device according to another embodiment of the present application.

In some embodiments, the overall architecture of the protocol parsing service in the control device is as shown in fig. 2D, and may include an application docking layer, a protocol parsing layer, a database, a protocol library, and a serial read/write layer.

The application docking layer may receive a common control signaling, an inquiry signaling, and a general device identification signaling sent by an upper layer application, and further feed back device state information included in a reply signaling to the upper layer application to display a control result, where the upper layer application may include a cigarette machine application, an air conditioner application, a refrigerator application, and the like.

The protocol analysis layer receives a signaling sent by the application docking layer, and calls a corresponding database according to the type of the signaling, wherein the database has the protocol analysis function of various products; the protocol analysis layer of the control device analyzes the signaling so that the terminal equipment and the control device can identify and process the signaling, and the database can be implemented as an air conditioner energy database, a smoke machine database, a refrigerator database and the like.

The protocol analysis layer is correspondingly applied to different communication protocols to interact with the terminal equipment in the process of calling the database to analyze the signaling;

for example, when the control device calls an air conditioner database, the controller communicates with the terminal equipment through a serial port communication protocol (Modbus); when the database of the cigarette machine or the database of the refrigerator is called, the controller communicates with the terminal equipment through a universal asynchronous receiving and transmitting transmission protocol.

For a conventional control device, communication is carried out on the basis of a preset fixed private protocol and different terminal equipment to realize control; the control device provided by the application can dynamically identify the terminal equipment connected with the interface based on the calling of the database in the protocol analysis service, realizes the communication between the control device and different types of equipment by the fact that the database comprises the universal read-write interface which can be supported by different equipment, and can analyze control, identification and display signaling related to different equipment further based on the analysis function and service provided by the database.

The database can be pre-stored in a storage module in the control device or immediately issued by a server, and dynamic identification and centralized control of different terminal devices by the control device can be realized by calling the database.

The serial port read-write layer receives the signaling processed by the protocol analysis layer, and then is responsible for initializing the serial port of the control device, specifically comprising setting parameter information such as a serial port node, a baud rate, a read-write node and the like, so that the signaling is sent to terminal equipment by the control device, wherein the terminal equipment can comprise the cigarette machine, an air conditioner, a refrigerator or other white electricity equipment.

In some embodiments, when the newly added first equipment air conditioner is connected to the control device interface, the user interface thereof will additionally display an air conditioner application icon corresponding to the air conditioner; a user can enter an air conditioner application program to control the air conditioner through physical keys or screen touch operation, as shown in fig. 1E;

in the control device user interface shown in fig. 1F, the user can set the air conditioner by using the operation interface, including setting the functions of temperature, mode, wind direction, timing, etc., and control the signaling and reply to the technical solution of the device status information display in the signaling, as described in the above embodiments.

For example, in fig. 1F, when a first device air conditioner accesses a first interface of the control device, and a user switches an operation mode from cooling to heating, the first controller receives a first control signaling input by the user in the user interface for controlling the first device air conditioner, where the first control signaling is used to adjust an air conditioner operation mode to heating;

under the scene that the control device loads the air conditioner database, the smoke machine database and the refrigerator database, assuming that the air conditioner database is a first database and the equipment type parameter of the air conditioner is a first type, after a user inputs the first control signaling, the first controller generates a corresponding first code according to the first type of the parameter, wherein the first code corresponds to the first database; it can also be understood that the first code, the first type and the first database have corresponding and associated relations; in some embodiments, the first encoding in question may also be referred to as a first protocol number.

A user operates an air conditioner application program, a system produces a first code in the process of sending out a control signaling, the first code can be generated based on the equipment type parameter of the air conditioner, and the first code can be used for a first controller to directly call a first database, so that the signaling is directly and efficiently processed. The first controller calls the corresponding first database to analyze the first control signaling based on the first code, so that the connected first equipment can recognize and process the first control signaling and send the first control signaling to the first equipment.

In the protocol analysis service, the application docking layer can determine which terminal equipment is connected to the control device currently by judging which databases exist; for example, the application docking layer may open the corresponding database in the background for verification; taking an air conditioner database as an example, if the air conditioner database can be opened in the background by applying a docking layer, the existence of the air conditioner database can be judged, the first controller can determine a code corresponding to the air conditioner, and the code can also comprise version information; similarly, the cigarette machine database and the refrigerator database are opened in the background by applying the docking layer, and the cigarette machine code and the refrigerator code are determined and acquired in the same way.

The application docking layer reports the currently supported terminal equipment to the control device, so that the control device updates the user interface, and can be set to only display the application program icons of the terminal equipment supported by the control device; during the reception of the reply signaling, the first controller will call the first database to parse the reply signaling according to the first type of parameter of the first device.

A user issues a control signaling containing codes through upper-layer application of a user interface of a control device, such as a cigarette machine application program, a refrigerator application program and an air conditioner application program; the protocol resolution service may invoke different databases according to different encoding implementations. In some embodiments, the database may be configured to support different model products corresponding to different secondary codes, meaning that the database cannot resolve that model product as not supporting the device when there is no corresponding secondary code in the database; if the secondary code is present in the database, the control means will display that the terminal device supports operating the device, as shown in figure 2E.

In some embodiments, when a second device of a second type is connected to the second interface and the first controller loads the second database corresponding to the second type, the user interface may display the corresponding controllable second device.

Taking the control device and the terminal device shown in fig. 1C as an example, assuming that only the third device, the refrigerator access interface 3, is available before, after the first device, the air conditioner access interface 1, the user interface of the control device will display the application icons of the refrigerator and the air conditioner; after the second device cigarette machine is continuously connected to the interface 2, if the first controller can successfully load the cigarette machine database corresponding to the cigarette machine, the control device can control the connected cigarette machine, and the user interface displays icons of a refrigerator, an air conditioner and a cigarette machine application program.

In some embodiments, when a second device of a second type is connected to the second interface and the first controller cannot load a second database corresponding to the second type or the control apparatus does not include the second database, it means that the control apparatus cannot control the second device; at this point, the controlling device user interface will not display the uncontrollable second apparatus.

For example, as shown in fig. 1D, assume that a first device, a cigarette maker, has heretofore been connected to interface 1, and a third device, a refrigerator, has been connected to interface 3; when a new second device television is connected to interface 2, if the control device cannot load the corresponding television database according to the device type parameters of the television, it means that the control device cannot perform centralized control on the television, and the user interface of the control device will not display the television application icons, but only the cigarette maker and refrigerator application icons.

Fig. 3A shows an overall architecture diagram of a control scheme of another embodiment of the present application.

In some embodiments, the application of the control apparatus may send the control signaling to the terminal device through a protocol parsing service of the control system; the control system is composed of a communication pipeline, an application docking layer, a protocol analysis layer, a channel protocol layer and a channel configuration layer.

In some embodiments, the control device may be implemented as a mobile terminal, or a smart centralized control screen or other control device.

For example, when the control device is implemented as a remote control device configured with a display screen, the user interface thereof may display a plurality of applications, each for controlling a different type of terminal equipment, including a cigarette pack, an air conditioning pack, or a refrigerator. The user can control the target terminal device across device types, systems, protocols and paths by the remote control device.

The communication pipe is used for transmitting a first control signaling sent by an application program to a system, and can be generally understood as a communication channel between an application docking layer and an upper layer application, or a communication channel realized by a multi-device interconnection service platform self-developed by a manufacturer.

And the application docking layer is used for receiving and forwarding the first control signaling sent by the upper layer application and receiving and reporting the state information fed back by the terminal equipment.

And the protocol analysis layer receives the first control signaling sent by the application docking layer, and converts the first control signaling into a second control signaling which can be identified and executed by the first terminal equipment by identifying the communication protocol supported by the first terminal equipment to be controlled by the first control signaling.

And the path protocol layer is configured to send the second control signaling according to a corresponding communication protocol based on the identified communication protocol corresponding to the first terminal device, and may include communication modes such as UART (universal asynchronous receiver transmitter), Modbus (serial communication), HCP (network communication), GATT (bluetooth universal attribute configuration), and the like.

And a path configuration layer, configured to set parameters such as a serial port and a baud rate according to the identified communication protocol, so as to send the second control instruction to the corresponding first device at the corresponding physical channel layer, where the first device is a control target of the first application, and specifically may include a smoke machine centralized control screen, an air conditioner centralized control screen, a refrigerator, or other white power equipment, as shown in fig. 3A.

For the situation that both the control device and the terminal equipment can load the system, it can be assumed that the control device sends a class A control signaling; for the situation that the control device can load the system and the terminal equipment cannot load the system, the control device can be assumed to send the class B control signaling; for the situation that the control device and the terminal equipment can not load the system, the control device can be assumed to send a C-type control signaling; generally, the A, B, C control signaling cannot be performed alternatively; however, with the control device and the system provided in the present application, the control device can send any one of the A, B, C control signals, and can control the terminal device through the control system.

In some embodiments, the communication modes supported by the path protocol layer, such as universal asynchronous receive/transmit transmission, serial communication, network communication, bluetooth universal attribute configuration, etc., are briefly described as follows:

the universal asynchronous receiving and transmitting transmission mode converts the transmitted data between serial communication and parallel communication, and is usually integrated on other communication interfaces when converting a parallel input signal into a serial output signal; the bus is in bidirectional communication, and full duplex transmission and reception can be realized; in embedded designs, for the host to communicate with the auxiliary device.

The serial communication is a serial communication protocol, is realized by a programmable logic controller, belongs to the industry standard of communication protocols in the industrial field, and is a common connection mode among industrial electronic equipment.

The Bluetooth general attribute configuration protocol is used for constructing a low-power Bluetooth peripheral, and the protocol stack is used for data communication with connected equipment, can be used for creating service, receiving information and processing requests; as a processing center, it can be used to scan, connect, discover services, and make responses.

FIG. 3B shows a schematic diagram of another embodiment of the present application control scheme in comparison to the prior art.

In some embodiments, in some general control systems, the control signaling sent by the control device is usually in a script language form, and the control signaling is sent to the terminal device through a Binder (inter-process communication) mechanism, and the terminal device that can be controlled by the terminal device must also usually be capable of loading an operating system supporting the script language;

the first control signaling sent by the control device provided by the application is sent to the control system through the communication pipeline, and the protocol parsing service of the control system can be implemented into a C language, for example, so that the first control signaling sent by the control device based on the script language form generates a second control signaling suitable for a current operating system and a single chip microcomputer through the protocol parsing service conversion of the control system, thereby realizing the control and interconnection of cross-system terminal equipment, as shown in fig. 3B.

The inter-process communication mechanism is an inter-process communication mechanism in the operating system; different applications run in different processes, and different components of the same application may also run in different processes; when a process wants to provide services to other processes, the services need to be provided by means of inter-process communication.

Service components such as those under APP1 may provide services for the calculator; when the APP2 also wants to use the computer service inside the APP1, since different APPs run in different processes, the APP2 is a computing service that cannot directly use the APP 1; for the type of cross-process call, the cross-process call can be completed only through an interprocess communication mechanism;

in some embodiments, the first control signaling sent by the first application further includes a device type parameter, which can be used for the application docking layer to identify the terminal device to which the first control signaling is directed; according to the device type parameter, the control system can call a database corresponding to the first device, which can also be called a model function module, so as to accurately forward the first control signaling to the protocol analysis layer.

For example, when the control system supports control of a smoke machine, an air conditioner and a refrigerator, after the corresponding application docking layer receives a first control signaling sent by a first application, the corresponding smoke machine centralized control screen functional module, the air conditioner centralized control screen functional module and the refrigerator functional module can be called according to the carried equipment type parameters so as to send the first control signaling to the protocol analysis layer; it can be understood that the device type parameter field can be distinguished by applying the docking layer, and then the application docking layer will call the corresponding device function block, so as to implement cross-device control of the control signaling, as shown in fig. 3C.

In some embodiments, the first control signaling sent by the first application further includes a protocol version parameter, and the protocol version parameter corresponds to a protocol type, for example, different protocol version parameters may respectively correspond to universal asynchronous receiver/transmitter transmission, serial communication, HCP protocol communication, and the like;

the protocol analysis layer generates a second control signaling based on the protocol version parameter carried by the first control signaling, and the second control signaling is suitable for a control protocol corresponding to a control target first device of the first application; the protocol analysis layer may identify the protocol type adapted to the second control signaling by identifying the protocol version parameter carried by the first control signaling, for example, implement the second control signaling as universal asynchronous receiver/transmitter transmission, or serial communication, or HCP protocol communication, so as to implement control and interconnection of the control device to the terminal device across protocols, as shown in fig. 3C.

In some embodiments, the first control signaling sent by the first application may further include a path parameter, and the path configuration layer may be configured to adapt to the second control signaling based on the path parameter, for example, the uart path adapts the uart communication mode, the bluetooth path adapts the serial communication mode, the lan adapts the HCP protocol communication; through the path parameters carried by the first control signaling, the control device can control and interconnect the terminal devices across the paths, as shown in fig. 3C.

In some embodiments, the control system protocol analysis service uses a built communication pipeline through a multi-device interconnection service platform self-developed by a manufacturer, so that multiple applications on an upper layer can realize cross-process call of system services, and specifically can be implemented to realize issuing services for a multi-device interconnection service subscriber and uploading services for a multi-device interconnection service platform provider;

for example, the application 1 and the application 2 respectively send out a control signaling request through the communication pipe, and after the control signaling is executed by the corresponding terminal device, the flow-to-flow service provided by the communication pipe immediately feeds back the control signaling request to satisfy the current command reply; in addition, the application 1 and the application 2 can also send signaling to the terminal equipment through a communication pipeline, the signaling is sent by the broadcast filtering service, and the signaling is fed back to the broadcast filtering service in real time through the broadcast service after being executed, and informs the corresponding application, so that the broadcast filtering meets the report of the change state.

In some embodiments, the control system can realize that the upper-layer application calls the system service in a cross-process mode through a JSON (JavaScript Object Notification) data exchange mode. The device type parameter, the protocol version parameter, the protocol type parameter and the operation parameter contained in the first control signaling can access the corresponding function table content, so that the protocol analysis service can meet the cross-system, cross-model and cross-path capabilities.

For example, the upper layer application sends a first control signaling containing the various parameters to a protocol analysis service of the control system, the control system communicates with the lower computer terminal device, and the uplink and downlink are realized in a JS object profile data exchange manner, so that the first control signaling identified by the control system is further converted into a second control signaling, and the second control signaling is adapted to different systems, device types, and different physical paths.

The object numbered musical notation is a light-weight data exchange format, and adopts a text format completely independent of a programming language to store and represent data; the simple and clear hierarchical structure enables the object numbered musical notation to become an ideal data exchange language; the method is easy for human reading and writing, and is also easy for machine analysis and generation, and the network transmission efficiency is effectively improved.

The beneficial effect of this application embodiment lies in, the beneficial effect of this application: by constructing a general equipment identification signaling sent to an interface, the dynamic identification of the access terminal equipment can be realized; further, association between the access terminal equipment and the database to be loaded can be realized by acquiring equipment type parameters; and further loading a corresponding database based on the device type, so that the signaling of different terminal devices can be analyzed, the access terminal devices can be dynamically identified and displayed based on the serial port, and the centralized control of the cross-type terminal devices can be realized.
