Example 3:
as shown in fig. 1, the present embodiment provides an intelligent device control method for controlling a plurality of intelligent devices through a control platform.
The control platform refers to a control device for uniformly controlling a plurality of intelligent devices, and examples of the control device include a controller of an intelligent home system, and a management platform set in a public city.
The intelligent device is a device capable of performing actual work under the control of the control platform, such as household appliances, doors and windows, lamps, vehicles and the like. Each intelligent device has one or more working options which can be set to different states, for example, the air conditioner has multiple different working modes (such as refrigeration, heating, dehumidification and the like) and different set temperatures, the lamp can be opened or closed, the door and the window can be opened or closed, and different opening degrees can be provided.
Each intelligent device stores a sub-database, and the sub-database at least comprises data corresponding to the working state of the intelligent device. When the data in the sub-database changes, the intelligent device can change the state of the intelligent device into the state corresponding to the data, and when the state of the intelligent device changes (for example, a user directly turns off a lamp, an air conditioner automatically enters a protection state due to overhigh temperature, and the like), the intelligent device can also modify the corresponding data in the sub-database.
Meanwhile, the data in the intelligent devices integrally form a distributed database. The distributed database is logically a database, but the data therein is stored in a plurality of different storage media (smart devices), respectively. The control platform can manage the distributed database, that is, each sub-database.
Specifically, the intelligent device control method of the embodiment may include the following steps:
s301, mutual authentication is conducted between the control platform and the intelligent device.
First, mutual authentication can be performed between the control platform and the smart device through the device ID, the control platform number, and the like, so that the control platform determines which smart devices it controls, and the smart device determines which control platform it is controlled by.
Specifically, the above authentication may be implemented only by the ID, but may also be implemented by other means such as encryption, and will not be described in detail herein.
S302, preferably, the control platform establishes a distributed database in a transversely-split data mode.
The horizontal partitioning (shading) refers to a management mode for partitioning the database according to a certain field (such as a device ID) in the data table. Because the primary purpose of this embodiment is to manage the smart device, and all information of any one must be related to its device ID, the management of the database is facilitated in a horizontal split manner.
Specifically, the data corresponding to the smart device may include data representing a state of the smart device, data representing attributes of the smart device, data representing trigger conditions of the smart device, and the like. Specifically, the above data may be logically stored in a large data table (of course, different parts of the data table may be actually stored in different intelligent devices), or may be distributed in a plurality of different data tables as shown in tables 1 to 3 below (of course, data for the same intelligent device in each table may be associated with each other). In each smart device, at least data (data in table 1 below) representing its own state is stored, and other data may be stored in the smart device or in the control platform.
TABLE 1 Intelligent device State Table
| Device ID | Device State 1 | Device State 2 | Device state 3 |
| SN0001 | Open | Refrigeration system | 26 degree |
| SN0002 | Open | Is free of | Is free of |
| …… | …… | …… | …… |
TABLE 2 Intelligent device Attribute Table
| Device ID | Device Property 1 | Device Property 2 | Device Properties 3 |
| SN0001 | Electrical appliance | Air conditioner | Room 1 |
| SN0002 | Electrical appliance | Lamp with a light source | Room 1 |
| …… | …… | …… |
TABLE 3 triggering condition table of intelligent device
| Device ID | Trigger Condition 1 | Trigger Condition 2 |
| SN0001 | Predetermined time 1 | Alarm system |
| SN0002 | Predetermined time 2 | Is free of |
| …… | …… | …… |
Of course, from the viewpoint of improving security, the control platform may also perform backup on the above distributed database, which is not described in detail herein.
S303, preferably, the client sends a control command to the control platform, where the control command includes a status required by the smart device.
That is, the user issues an instruction to the control platform as needed to expect the operation of the smart device, that is, an instruction of what state the smart device is expected to have. For example, it is desirable that the air conditioner is set to a cooling mode and the set temperature is 26 degrees; it is desirable to have all appliances in room 1 turned off; it is desirable to close the window first and then open the air conditioner, etc.
The client can be a device for providing a control command to the control platform, such as a dedicated terminal or a mobile phone of a user; alternatively, the client may also be an interactive interface or an input module of the control platform itself.
The specific manner in which the user issues the above control command is also various. For example, the operation to be performed on the smart device may be selected through a specific interactive interface, or may be selected from a predetermined database statement template, and the like.
S304, the control platform receives a control command from the client.
S305, the control platform generates a database instruction according to the control command, wherein the database instruction is a database statement for modifying data in a sub-database in the intelligent device.
That is to say, the control platform determines which states of which intelligent devices are to be controlled according to the control commands, generates corresponding database instructions, and modifies corresponding data in the sub-databases in the corresponding intelligent devices by using database statements.
In this step, the control command may be translated (converted) into a corresponding database statement according to a preset rule, or a database statement template provided by the client may be checked, for example.
S306, the control platform sends a database instruction to the intelligent device.
That is, the control platform issues the above control commands to the concerned smart devices. It can be seen that, for the control platform, what is done in this step is completely a modification operation on the distributed database, and the operation of the database statement on the database is very flexible. For example, in this step, all the fields of "device attribute 3" are "room 1", and the field of "device state 1" of the data of "device attribute 1" is "appliance" is modified to "off".
Therefore, the method of the embodiment is very convenient to operate and manage, and can easily realize centralized control, linkage control and the like of mass intelligent equipment.
Specifically, when a plurality of intelligent devices are to be controlled, different database instructions may be sent to different intelligent devices; the same database command may be issued to a plurality of intelligent devices, and each intelligent device determines which data should be modified according to the device ID and the like.
Preferably, the above database statement is preferably in SQL language.
SQL sentences are standard languages used for controlling the relational database, can flexibly control each field of the relational database, and are allowed to be nested with each other, so that the processing capability of the relational data is very strong, and the centralized control and the linkage control can be realized most easily.
And S307, the intelligent equipment receives a database instruction from the control platform.
And S308, the intelligent equipment modifies the data in the sub-database according to the database instruction.
After receiving a database instruction (database statement), the intelligent device modifies data in the sub-database according to the database instruction. Obviously, this step actually falls within the scope of making modifications to the database.
S309, the intelligent device changes to the state corresponding to the data in the modified sub-database.
After the data in the sub-database is modified, the state of the intelligent device may become no longer corresponding to the data in the database, and at this time, the intelligent device may modify the state of the intelligent device to match the state with the data in the sub-database, thereby implementing the control of the intelligent device.
In the step, after modifying the data in the sub-database each time, the intelligent device actively adjusts the state corresponding to the modified data; or a process is set in the intelligent device to poll and monitor each field (data) of the sub-database, and when the data is found not to correspond to the state of the intelligent device, the state of the intelligent device is correspondingly changed.
Of course, if the state of the intelligent device is actively changed, the sub-database thereof can be modified correspondingly.
And S310, preferably, the intelligent equipment feeds the modified state back to the control platform.
That is, the smart device informs the control platform of the result of the state modification.
And S311, preferably, the control platform receives the state information fed back by the intelligent device.
That is, the control platform receives the feedback of the intelligent device, so as to know whether the intelligent device successfully changes the state, and specifically modifies the backup database or re-sends a database instruction, and the like.

the embodiment provides a control platform, which is used for controlling the states of a plurality of intelligent devices, wherein each intelligent device is stored with a sub-database, each sub-database comprises data corresponding to the state of the intelligent device in which the sub-database is located, and the sub-databases in the plurality of intelligent devices jointly form a distributed database; the control platform includes:
and the instruction sending unit is used for sending a database instruction to the intelligent equipment, wherein the database instruction is a database statement for modifying data in a sub-database in the intelligent equipment.
