In order to remotely control and manage the external devices, an internet of things gateway is generally added on the basis of a central control device at present, so that a cloud server can control and manage each external device through the central control device by using the internet of things gateway.

In order to solve the problems of large development workload, high development cost, great use limitation and resource waste caused by the fact that a cloud server cannot be universally used for various types of central control equipment in the related technology, the invention provides a central control adaptation method. Therefore, all standard equipment can be directly watched in the cloud server, and the cloud server can directly manage or control the standard equipment through the unified communication protocol of the standardized equipment without the need of any control protocol adopted by the equipment in mind. After the cloud server issues the issued data packet for managing or controlling the standard equipment, the issued data packet is analyzed by using the communication protocol matched with the cloud server, and then the central control communication protocol matched with the current central control equipment is selected from the central control communication protocols prestored in various different types to convert the analyzed data, so that the operation instruction which can be identified by the central control equipment can be obtained, and the central control equipment can perform corresponding control operation according to the operation instruction. Therefore, the communication between the central control equipment and the cloud server can be isolated, and the central control equipment can respond to the control and management of the cloud server without any change; the cloud service end does not need to pay attention to a control protocol of the central control equipment, does not need to customize different communication protocols for different central control equipment, does not need to pay attention to whether the bottom layer is accessed to the existing standardized equipment or virtual standard equipment virtualized by a main body applied by the central control adaptation method and a third party central control, and can realize the transparent control and management of the central control equipment of different manufacturers by the cloud service end only by directly realizing the control and management of the standardized equipment through a uniform protocol instruction. The method is favorable for realizing the isolation between the cloud server and the Internet of things gateway and the central control equipment, reduces the integration difficulty of the whole system, can realize the control and management of the central control equipment of different types by manufacturing one cloud server, is favorable for improving the application range, the practicability and the effective utilization rate of the cloud server, and simultaneously reduces the development workload of the cloud server and the development cost of the cloud server.
The central control adaptation method of the embodiment of the invention can be applied to equipment with operation processing capability, and the equipment can be an independent product, which can be understood as follows: the device can be used as a product separated from the central control device, the internet of things gateway and the cloud server, and when the device needs to be applied, the device only needs to be in communication connection with the central control device and the internet of things gateway respectively, as shown in fig. 1, the device can be a central control adaptive device. Therefore, when the system is applied, the central control adaptive device can establish communication connection with the central control device in an RS485 or RS232 or wifi or Ethernet mode, and can establish communication connection with the Internet of things gateway in an RS485 or RS232 or wifi or Ethernet or Bluetooth mode. Therefore, when the cloud server sends a data packet related to management and control, the central control adaptation device can receive the data packet through the internet of things gateway, analyze and convert the data packet, and then send the data packet to the central control device, and the central control device executes corresponding operation. Therefore, successful communication between the cloud server and various types of central control equipment is achieved, and the cloud server can control various types of central control equipment through a unified communication protocol.
The following describes a central control adaptation method provided by an embodiment of the present invention specifically:
as shown in fig. 2, the central control adaptation method includes the following steps:
in step S021, determining, according to the model of the central control device currently establishing the communication connection, a control function instruction that can be applied to each external device by the external device and the central control device;
in step S022, for each external device, recording a mapping relationship between the external device and a corresponding control function command thereof;
in step S023, for each external device, determining a device type of the external device, generating a virtual standard device and a unique identification code of the external device, and mapping the virtual standard device, the device type, and the unique identification code of the external device to a corresponding mapping relationship;
in step S024, each virtual standard device, the device type and the unique identification code thereof are sent to a cloud server;
in step S025, when an issued data packet sent by the cloud server is received, the issued data packet is sequentially analyzed and protocol-converted to obtain an operation instruction matched with a control protocol of the central control device; the protocol conversion is realized by calling corresponding central control communication protocols from a plurality of pre-stored central control communication protocols of different types according to the models of the central control equipment, and any operation instruction carries the unique identification code of the corresponding virtual standard equipment;
in step S026, the operation instruction is mapped to the mapping relationship of the unique identification code carried by the operation instruction, and the operation instruction is sent to the central control device, so that the central control device updates the control of the corresponding external device according to the operation instruction.
It should be noted that in the central control adaptation method according to the embodiment of the present invention, a currently known central control communication protocol applied by all central control devices and a communication protocol capable of communicating with a cloud server are embedded in a computer program for implementing the method in a development stage; wherein the communication protocol may be a standardized internet communication protocol. Therefore, the device applying the central control adaptation method can respectively carry out effective communication with the central control device and the cloud server through the two-party protocol, can analyze and convert a data packet sent by the cloud server into an operation instruction which can be identified by the central control device through the cooperative work of the two-party protocol, and can analyze and convert a data packet sent by the central control device into a message which can be identified by the cloud server through the cooperative work of the two-party protocol. In addition, in the central control adaptation method according to the embodiment of the present invention, a currently known model number of all central control devices and a central control device control function corresponding to each model number are also embedded in a computer program for implementing the method in a development stage, where the central control device control function may include but is not limited to: the total number of interfaces of the central control equipment, the types of the interfaces and all control instructions allowed to be transmitted by each interface.
The following description describes a process of managing and controlling the central control device by the cloud server through steps S021 to S026:
after the device applying the central control adaptation method establishes communication connection with the central control device and the internet of things gateway respectively, firstly, according to the model of the central control device which establishes the communication connection at present, the model which is the same as the model of the current central control device is selected from a prestored central control device model database. Then the selected model determines the total number of interfaces, the types of interfaces, and all control commands allowed to be transmitted by each interface of the central control device, and then, the total number and types of external devices that can be controlled by the central control device can be determined according to the total number of interfaces and the types of interfaces, and further, the control function command of the central control device to each external device can be determined according to all control commands allowed to be transmitted by each interface, for example, assuming that the total number of interfaces of the central control device is 10, wherein the types of 2 interfaces are audio outputs, wherein the types of 2 interfaces are audio inputs, wherein the types of 2 interfaces are network ports, wherein the types of 2 interfaces are lighting device accesses, wherein the type of 1 interface is video input, and the type of the last 1 interface is video output, based on this, it is known that 2 interfaces are network ports according to the total number of interfaces and the types of interfaces, for accessing a network, generally speaking, a cloud server does not need to control the networking condition of the central control device, and therefore the 2 interfaces can be omitted; and other interfaces are interfaces for controlling multimedia devices, and generally, a cloud server needs to implement management and control on the multimedia devices through a central control device. Therefore, in this case, the total number of external devices that can be controlled by the central control device is considered to be 8, and the control function command for each external device by the central control device is determined according to the type of the interface and the control command that the interface can allow to transmit, for example, for the light equipment interface, the control function command may include but is not limited to: turning on the lamp, turning off the lamp, dimming the light and turning on the light.
After determining the external devices which can be controlled by the central control device and the control function commands which can be applied to each external device, recording the mapping relation between each external device and the corresponding control function commands thereof. In one example, each external device and its corresponding control function command may be recorded in a tabular manner; in another example, each external device and its corresponding control function instructions may be recorded in an aggregate manner. In this example, in order to improve the efficiency of searching for the control function command of the external device, a table mode is adopted to record each external device and the corresponding control function command thereof.
After or at the same time as the mapping relationship is recorded, the device type of the external device is also added to the mapping relationship of each external device, the device type of the external device may be determined by the interface type of the central control device, and for how to determine, reference may be made to the above description, which is not described herein again. In the process, for each external device, the external device is also virtualized into a corresponding virtual standard device, and a corresponding unique identification code is generated. After the standard virtual equipment and the unique identification code of each piece of equipment are generated, the corresponding standard virtual equipment and the corresponding unique identification code are added into the mapping relation of each piece of external equipment. In this way, in the initial state, the mapping relationship includes: and the corresponding relation between the external equipment and the corresponding control function instruction, the equipment type, the virtual standard equipment and the unique identification code.
And then, sending each virtual standard device, the device type and the unique identification code thereof to a cloud server through the Internet of things gateway. Thus, as shown by reference sign b in fig. 3, in an application view of the cloud service end, the architecture of the management and control system that can be observed is composed of the cloud service end, the internet of things gateway, and a plurality of standard devices, and can be understood as follows: after the steps S021 to S024 are executed, the cloud service end can realize that the cloud service end directly communicates with a plurality of standardized devices through the internet of things gateway, and unified management and control are realized. Therefore, the cloud server only needs to send unified management and control messages, and does not need to pay attention to the central control equipment. However, it should be noted that, as shown by reference sign a in fig. 3, the actual management and control system is composed of a cloud service end, an internet of things gateway, a central control adaptation device and a central control device.
Therefore, the steps S021 to S024 lay a foundation for realizing effective communication between the cloud server and the central control equipment. However, if steps S021 to S024 are executed after each connection is established with the central control device, and the mapping relation list and the virtual device, the unique device number, and the like in the central control adaptation device are reconfigured, so that in a situation where the central control device that establishes communication this time is the same as the central control device that establishes communication last time, unnecessary configuration operation is obviously caused, unnecessary calculation resources are occupied, and adaptation efficiency is reduced. Since steps S022 to S024 are performed after step S021 is performed, it can also be considered that steps S022 to S024 are also performed when it is determined that the model of the central control device currently establishing the communication connection is different from the model of the central control device that has last established the communication connection. Therefore, under the condition that models of central control equipment for continuously establishing communication are the same, the first configuration information can be directly applied without repeated configuration, and the method is beneficial to improving the adaptation efficiency and reducing the occupation of calculation resources.
After the configuration is completed, if an issued data packet sent by the cloud server is received, the issued data packet may be sequentially analyzed and protocol-converted to obtain an operation instruction matched with the control protocol of the central control device. The protocol conversion is realized by calling corresponding central control communication protocols from a plurality of pre-stored central control communication protocols of different types according to the model of the central control equipment; any operation instruction carries the unique identification code of the corresponding virtual standard equipment. In order to facilitate understanding of the delivered data packet, an example illustrates contents that the delivered data packet may contain: suppose that the cloud server wants to control the virtual standard device a with the device type of light to be turned on, and the device state is lighting. Based on this, the issued data packet may include, but is not limited to, the following device information: the method comprises the following steps of virtual standard equipment A, equipment type, unique identification code, control instruction of 'on' and equipment state of 'lighting'. Therefore, when the issued data packet of the above example is received, the issued data packet can be analyzed through the communication protocol of the cloud server, and corresponding device information such as a device type, a unique identification code and a control instruction or a device type and a control instruction carrying the unique identification code is obtained through analysis; and then converting the equipment information into an operation instruction which can be identified by the central control equipment through a central control communication protocol. It should be noted that one delivered data packet may include device information of one or more virtual devices.
After the operation instruction is obtained, the operation instruction can be mapped to the mapping relation where the unique identification code carried by the operation instruction is located, so that the recorded record of the external equipment controlled by the cloud service end or the state of the external equipment is updated, the operation instruction is sent to the central control equipment, the central control equipment can update the control of the corresponding external equipment according to the operation instruction, and the cloud service end can control the external equipment through the central control equipment.
It should be noted that, if there are a plurality of operation instructions obtained through analysis, for example, when the operation instructions include a plurality of instructions for respectively controlling a plurality of external devices, in order to avoid that the operation instructions occupy too many communication resources and increase the number of times of communication one by one, thereby causing a decrease in communication efficiency, in an embodiment, before the operation instructions are sent to the central control device, the operation instructions may be packaged into a central control data packet that can be recognized by the central control device through a central control communication protocol. After the central control device receives the central control data packet, the central control data packet can be analyzed to obtain a plurality of operation instructions, and the control of the corresponding external device is updated according to each operation instruction.
In the foregoing, in the step S025, the sequentially parsing and protocol converting the transmitted data packet may include the following steps:
in step S0251, the issued data packet is analyzed through a cloud analysis protocol matched with the cloud server communication protocol to obtain device information of the virtual standard device currently required to be managed by the cloud server, where the device information includes at least one of the following: state information and control information of the virtual standard equipment; the state information and the control information both carry the unique identification code of the corresponding virtual standard equipment;
in step S0253, calling a corresponding central control communication protocol from a prestored central control protocol analysis library according to the model of the central control equipment, and converting the equipment information into an operation instruction matched with the control protocol of the central control equipment through the called central control communication protocol; and the central control protocol analysis library stores a plurality of different types of central control communication protocols.
Therefore, through the steps S0251 and S0253, the correctness of the sequence of processing the issued data packet can be ensured, the protocol conversion is ensured to be carried out only after the issued data packet is analyzed, errors in the analyzing and protocol conversion processes caused by the disorder of the two steps are avoided, and the correct processing program of the issued data packet and the errors in the processing process are effectively ensured.
Although the processing of the delivered data packet may be implemented by any of the embodiments described above, the delivered data packet may include device information of multiple pieces of virtual standard devices from the cloud service end, and if the protocol conversion processing is performed on the device information of the multiple pieces of virtual standard devices at random after the delivered data packet is analyzed, the information obtained after conversion may be too confused, and is not favorable for sorting and delivering to the central control device. Therefore, to at least solve this technical problem, in an embodiment, before the step S0253, the parsing and protocol converting the issued packet in sequence may further include the following steps S02521 or S02522:
in step S02521, the device type of the corresponding virtual standard device is determined according to the unique identification code carried by the device information, and the device information is classified according to the device type, so that the device information with the same device type is included in the same information set.
In step S02522, the device information is classified according to the unique identification code carried by the device information, so that the state information and the control information with the same unique identification code are classified into the same information set.
That is to say, after the data packet is sent by analysis, all the analyzed device information can be classified according to the device type, the device information of the same device type is put into the same information set, and then the protocol conversion is carried out by taking the information set as a unit, so that after the protocol conversion, the device information of the same device type is still in the same information set, and is conveniently and sequentially packed into a plurality of groups of data packets according to different device types, and then the data packets are sent to the central control device, and the device information is conveniently and orderly mapped into corresponding mapping relations, so that the data management is more effective and clear. In other examples, of course, all the analyzed device information may be classified according to the unique identifier code in the manner of step S02522, the state information and the control information having the same unique identifier code are put into the same information set, and then protocol conversion is performed in units of the information set, so that different subsequent unique identifier codes may be conveniently packaged into a plurality of data packets, and the data packets are sent to the central control device, and the device information is conveniently and orderly mapped into corresponding mapping relationships, so that data management is more efficient and clear.
Based on the embodiment of step S02521 or step S02522, accordingly, step S0253 can be adaptively adjusted to: and calling a corresponding central control communication protocol from the central control protocol analysis library according to the model of the central control equipment, and converting the equipment information in each information set into an operation instruction matched with the control protocol of the central control equipment through the called central control communication protocol.
In some cases, the cloud service end issues device information for a plurality of virtual standard devices, but for the virtual standard devices, the cloud service end may want the central control device to sequentially respond to operations on the plurality of virtual standard devices according to a certain order, and therefore, in order to meet this management and control requirement, in an embodiment, for each external device, a priority is also recorded in a mapping relationship of the external device; the priority is used for representing the processing sequence of the device information of the external device relative to the device information of other external devices. After the distributed data packet sent by the cloud server is analyzed, the processing sequence of each piece of equipment information can be determined according to the unique identification code corresponding to each piece of equipment information in the corresponding mapping relation, and then the protocol conversion operation is performed on each piece of equipment information in sequence according to the determined processing sequence.
Based on the embodiment obtained by combining the previous embodiment with step S02521 or step S02522, since the same information set may include multiple pieces of information, some pieces of information may need to be processed in time, and the processing timing of some pieces of information is not very important, in order to meet the management and control requirements of more cloud servers and improve the control rationality of the cloud servers, in an embodiment, the priority may include an external priority and an internal priority; the external priority is used for representing the processing sequence among the information sets, and the internal priority is used for representing the processing sequence among the information sets in the same information set. Based on this, the step S0253 can be adaptively adjusted to: calling a corresponding central control communication protocol from the central control protocol analysis library according to the model of the central control equipment, and processing each information set in sequence through the called central control communication protocol according to the external priority of each information set; and in the process of processing each information set, sequentially converting the equipment information into an operation instruction matched with a control protocol of the central control equipment through the called central control communication protocol according to the internal priority of the equipment information in each information set.
In addition, although the cloud server can manage and control the external device connected to the central control device through the above process, in order to enable the cloud server to timely know whether the central control device manages and controls the corresponding external device according to the requirement and to ensure the accuracy of the management and control of the external device, in an embodiment, the central control adaptation method further includes a step of feeding back a response result of the central control device to the cloud server, that is, the central control adaptation method may further include the following steps:
in step S031, when an upload data packet sent by the central control device is received, the upload data packet is parsed to obtain actual device information; wherein the upload data packet is generated by the central control device in response to the operation instruction or according to a local control operation, and the device actual information includes at least one of the following: actual state information of the external device, control response; the actual state information and the control response both carry a unique identification code of corresponding external equipment;
in step S032, the device actual information is converted into an actual operation state and/or a working response of the virtual standard device supported by the cloud server, and the actual operation state and/or the working response are mapped to a mapping relationship of the corresponding virtual standard device;
in step S033, the actual operation state and/or the work response of each virtual standard device is packaged into a state data packet of the corresponding virtual standard device according to the communication protocol of the cloud server, and is sent to the cloud server.
Through the steps S031 to S033, the actual state information of the device and the control response sent by the central control device may be fed back to the cloud server, so as to implement effective management and control of the cloud server.
For convenience of understanding of actual state information and control response of the external device, for example, the actual state information is used to represent an actual operating state of the external device, for example, for a lighting device, if the actual operating state is on, the actual state information may be "on", or may be represented by 0 or 1, for example, when 0 is on, 1 is off, or vice versa; of course, other languages may be used to convey the present invention, and the present invention is not limited thereto. The control response may be a response or no response, for example, the cloud service end wants to light up, but actually lights up, so the control response may be "in response," and may be represented by 0 or 1, or may be represented by a language that can be understood by other computers, which is not limited by the present invention.
It should be noted that various technical features in the above embodiments can be arbitrarily combined, as long as there is no conflict or contradiction between the combinations of the features, but the combination is limited by space and is not described one by one.
