An embodiment of the present invention provides a method for controlling an internet of things device, and fig. 1 is a schematic flow chart of the method for controlling the internet of things device provided by the embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
In step 101, the first control instruction refers to an instruction for controlling the internet of things device to execute a corresponding operation, and includes but is not limited to an opening instruction, a closing instruction, an alarm instruction, a pause instruction, or a working mode switching instruction. The first control instruction may include: the controller identification, the control object identification and the indication information of the to-be-presented state of the control object.
The indication information of the to-be-presented state of the control object is used to indicate the to-be-entered state of the control object, for example, taking an electric lamp as an example, the to-be-entered state may include: a lit state or an extinguished state.
In the embodiment of the invention, the control object is an internet of things device associated with a controller, and can realize corresponding functions under the control of the controller.
Illustratively, the control objects include, but are not limited to: the intelligent teaching device comprises intelligent household equipment, intelligent office equipment and/or intelligent teaching equipment.
For example, the smart home device may include: electric curtains, intelligent lights and water heaters; the user sends a control instruction to the cloud platform through the mobile terminal, and the control instruction is a water heater starting instruction. The cloud platform issues the control command to the Internet of things gateway, and the Internet of things gateway sends the control command to the first controller; after receiving the control instruction, the first controller monitors the control state information of the second controller; and if the control state information of the second controller indicates that the water heater is in a closed state. And the first controller broadcasts the control instruction so that the second controller receives the control instruction and controls the water heater to be started.
For another example, the intelligent office equipment may include: intelligent electric light, heating installation and large-screen display equipment. And a user sends a control instruction to the cloud platform through the terminal, wherein the control instruction comprises a control instruction for turning on the intelligent electric lamp in the conference room and a control instruction for turning on the large-screen display device. The cloud platform issues the control command to the Internet of things gateway and issues the control command through the Internet of things gateway; after the first controller monitors the control instruction, the first controller controls the intelligent electric lamp in the conference room to be turned on according to the control instruction for turning on the intelligent electric lamp in the conference room; the first controller monitors the control state information sent by the second controller; if the control state information of the second controller indicates that the large-screen display device is in a closed state, the first controller broadcasts a control instruction for opening the large-screen display device, so that the second controller receives the control instruction for opening the large-screen display device and controls the large-screen display device to be opened.
As another example, the intelligent teaching device may include a multimedia display device and a multimedia speaker device. The user sends a control instruction to the cloud platform through the terminal, wherein the control instruction is an opening instruction for multimedia display equipment and multimedia sound box equipment in all classrooms of a certain teaching building. The cloud platform issues the control command to the Internet of things gateway and issues the control command through the Internet of things gateway; after the first controller monitors the control instruction, the multimedia display equipment and the multimedia sound box equipment in all the classrooms of the teaching building are controlled to be started according to the control instruction.
In some embodiments, the control objects controlled by the first controller and the second controller may both be the same type of internet of things device, for example, the controlled device may be a smart lamp in a classroom or a library; alternatively, the devices being controlled may also each be a large screen display device of a classroom or projection room.
In other embodiments, the control objects controlled by the first controller and the second controller may be different types of internet of things devices.
The method comprises the steps that a first controller monitors a first control instruction sent by the gateway of the Internet of things, analyzes the first control instruction, and determines a controller identifier, a control object identifier and indication information of a to-be-presented state of a control object, wherein the controller identifier, the control object identifier and the indication information are carried by the first control instruction.
It should be noted that the controller identifier is identifier information of a controller to which the internet of things device indicated by the first control instruction belongs, and the control object identifier is a device identifier of the internet of things device indicated by the first control instruction. The controller identification and the control object identification have an association relationship.
In step 102, the control state information is used to indicate a current state of a controlled object associated with the controller. The current state includes: an operating state and a non-operating state;
wherein the working state represents that the controlled object is in an open state; the non-working state represents that the controlled object is in a closed state.
In some embodiments, the operating state may also be used to indicate a power consumption condition of the controlled object; the operating state may include: a first operating state, a second operating state and a third operating state. And the power consumption of the first working state is lower than that of the second working state, and the power consumption of the second working state is lower than that of the third working state. For example, the first operating state may be a low power consumption state, the second operating state may be a medium power consumption state, and the third operating state may be a high power consumption state.
For example, the first control instruction is an instruction for switching the working mode to the low power consumption state, and the first controller monitors the first control instruction and a control state instruction sent by the second controller; determining that a control object controlled by the second controller is in a high power consumption state according to the control state information; and the first controller broadcasts the first control instruction, so that the second controller receives the first control instruction and controls the control object to switch the working mode from the high power consumption state to the low power consumption state.
The control state information includes: a controller identification, a control object identification, and an indication of a current state of the control object.
The first controller listens to the control state information, and can determine the internet of things equipment and the current state of the internet of things equipment, to which the control state information is directed, according to the controller identifier, the control object identifier and the indication information of the current state of the control object in the control state information.
In step 103, the first state is a current state of a control object associated with the second controller indicated by the control state information; the second state is a state to be presented of the control object indicated by the first control instruction.
The first controller determines a second state of the Internet of things equipment to which the first control instruction is directed according to the controller identifier, the control object identifier and the indication information of the state to be presented of the control object in the first control instruction; determining a first state of the control object indicated by the control state information according to the controller identifier, the control object identifier and the indication information of the current state of the control object in the control state information; and determining whether the Internet of things equipment needs to execute the first control instruction or not according to the comparison between the first state and the second state.
It should be noted that the first controller determines whether the internet of things device needs to execute the first control instruction by comparing the first state with the second state; on one hand, when the first state is not matched with the second state, namely the second controller exceeds the communication range of the Internet of things gateway or the second controller and the Internet of things gateway have communication faults, the first controller broadcasts the first control instruction to ensure that the Internet of things gateway effectively controls the Internet of things equipment; on the other hand, under the condition that the first state is matched with the second state, namely the IOT equipment does not need to execute the first control instruction, the interference of unnecessary broadcast on the communication between the IOT gateway and the controller and the communication between the controller and the controller is reduced.
If the first state is not matched with the second state, it is determined that the Internet of things equipment needs to execute the first control instruction, and the first controller broadcasts the first control instruction, so that the second controller controls the Internet of things equipment to execute the first control instruction after receiving the first control instruction.
For example, a first controller monitors a first control instruction aiming at a second controller and sent by an internet of things gateway, and determines that the first control instruction is used for controlling the intelligent electric lamp controlled by the second controller to be turned on according to the first control instruction; the first controller monitors the control state information sent by the second controller; according to the control state information, determining that the intelligent electric lamp controlled by the second controller is in a closed state; the first controller will broadcast the first control instruction.
In some embodiments, the first control instruction comprises: the instruction issuing time; the control state information includes: the status update time.
The step 103 comprises:
and according to the first control instruction and the control state information, when the first state of the controlled object controlled by the second controller is determined to be not matched with the second state indicated by the first control instruction, and the time difference between the instruction issuing time of the first control instruction and the state updating time of the control state information is greater than the preset time difference, broadcasting the first control instruction.
In practical application, the first controller determines a second state of the internet of things device to which the first control instruction is directed and a first state of the internet of things device to which the first control instruction is directed according to the first control instruction and the control state information of the second controller.
When the first state is not matched with the second state, acquiring instruction issuing time in the first control instruction and state updating time in the control state information;
if the state updating time is earlier than the instruction issuing time, continuing to monitor the control state information sent by the second controller;
if the state updating time is later than the instruction issuing time, determining a time difference value;
if the time difference value is larger than a preset time difference, determining that the Internet of things equipment does not execute the first control instruction, and broadcasting the first control instruction by a first controller;
and if the time difference is smaller than the preset time difference, continuing to monitor the control state information sent by the second controller.
It should be noted that, in the embodiment of the present invention, the first control instruction carries the instruction issuing time and the control state information carries the state updating time, on one hand, a situation that there may be a delay in communication between the controller and the controller is considered, if the state updating time is earlier than the first control instruction, it is described that there may be a delay in communication between the first controller and the second controller, and the control state information may not accurately indicate the current state of the internet of things device controlled by the second controller. To reduce unnecessary broadcasts, the second controller's control state instructions may continue to be snooped.
On the other hand, when the controller acquires the current state of the internet of things device for broadcasting after controlling the internet of things device to execute the corresponding instruction, if the current state is inconsistent with the state indicated by the control instruction, secondary control on the internet of things device may be triggered. If the time difference between the instruction issuing time and the state updating time is smaller than the preset time difference, the control state instruction of the second controller can be continuously monitored in order to reduce unnecessary broadcasting.
Illustratively, the first control instruction is a start instruction for controlling the intelligent electric lamp 2, and after the first controller monitors the first control instruction and the control state information sent by the second controller, when it is determined that a first state indicated by the control state information is not matched with a second state indicated by the first control instruction, the instruction issuing time in the first control instruction and the state updating time in the control state information are obtained;
if the state updating time is earlier than the instruction issuing time, determining that there may be a delay in the communication between the first controller and the second controller, and the control state information cannot accurately indicate the current state of the intelligent electric lamp 2; the first controller continues to listen to the control status information sent by the second controller to determine whether the smart lamp 2 needs to execute the first control instruction.
If the state updating time is later than the instruction issuing time and the time difference value is smaller than the preset time difference, the situation that the second controller controls the intelligent electric lamp 2 to be started again may exist, and the first controller continues to monitor the control state information sent by the second controller.
If the state updating time is later than the instruction issuing time and the time difference is larger than the preset time difference, it is indicated that the second controller may not receive the first control instruction, and the first controller broadcasts the first control instruction, so that the second controller receives the first control instruction and controls the intelligent electric lamp 2 to be turned on.
Optionally, the method further comprises:
and if the control object indicated by the first control instruction is the controlled object controlled by the first controller, controlling the controlled object controlled by the first controller to switch the state according to the first control instruction.
In practical application, the first controller determines that the control object indicated by the first control instruction is the internet of things equipment controlled by the first controller according to the controller identifier and the control object identifier in the first control instruction; and the first controller controls the Internet of things equipment to be switched to the state to be presented from the current state according to the indication information of the state to be presented of the control object.
For example, the first control instruction is a start instruction for the intelligent fan controlled by the first controller; after the first controller monitors the first control instruction, the first controller controls the intelligent electric fan indicated by the first control instruction to execute a starting operation according to the identification information of the controller and the identification information of the control object in the first control instruction, so that the intelligent electric fan is switched from a non-working state to a starting state.
Optionally, the method further comprises:
monitoring a second control instruction broadcast by the second controller;
determining whether the control object indicated by the second control instruction is the controlled object controlled by the first controller;
and if the control object indicated by the second control instruction is not the controlled object controlled by the first controller, broadcasting the second control instruction.
In the embodiment of the invention, the first control instruction is a control instruction directly sent by the gateway of the internet of things; the second control instruction is a control instruction which is sent by the gateway of the internet of things and broadcasted by the controller. Wherein the second control instruction may include: the controller identification, the control object identification and the indication information of the to-be-presented state of the control object.
The determining whether the control object indicated by the second control instruction is the controlled object controlled by the first controller includes:
acquiring a controller identifier and/or a control object identifier in the second control instruction, and comparing the controller identifier and/or the control object identifier in the second control instruction with the identifier information of the first controller and/or the equipment identifier of the controlled object of the first controller; and determining whether the control object indicated by the second control instruction is the controlled object controlled by the first controller or not according to the comparison result.
In practical application, if the comparison result indicates that the control object indicated by the second control instruction is not the controlled object controlled by the first controller, the first controller broadcasts the second control instruction, so that the controller to which the second control instruction is directed can receive the second control instruction.
It should be noted that when the internet of things gateway issues a control instruction for one or more controllers, the controller fails to receive the control instruction issued by the internet of things gateway due to the fact that the distance between the controller and the internet of things gateway exceeds the communication range or a communication fault exists between the controller and the internet of things gateway; after monitoring a control instruction issued by the gateway of the internet of things, other controllers broadcast the control instruction when determining that the control object indicated by the control instruction is not the controlled object controlled by the other controllers according to the control instruction, so that when the controller and the gateway of the internet of things exceed a communication distance or have communication obstacles, the other controllers receive the control instruction through the control instruction broadcast by the other controllers, and execute the control instruction.
Optionally, the method further comprises:
and if the controlled object indicated by the second control instruction is the controlled object controlled by the first controller and the state of the controlled object controlled by the first controller is determined to be inconsistent with the state indicated by the second control instruction, controlling the controlled object controlled by the first controller to switch the state according to the second control instruction.
In practical application, the first controller obtains the control object identifier in the second control instruction, compares the control object identifier with the device identifier of the internet of things device controlled by the first controller, and determines whether the control object indicated by the second control instruction is the controlled object controlled by the first controller. If the comparison result represents that the control object indicated by the second control instruction is the controlled object controlled by the first controller, acquiring indication information of the state to be presented of the control object in the second control instruction; determining whether the current state of the Internet of things equipment indicated by the control object identifier is consistent with the state to be presented indicated by the second control instruction or not according to the indication information; if the current state of the internet of things equipment indicated by the control object identifier is inconsistent with the to-be-presented state indicated by the second control instruction, the first controller controls the internet of things equipment indicated by the control object identifier to execute a corresponding instruction, so that the internet of things equipment switches the current state into the to-be-presented state.
Optionally, the method further comprises:
broadcasting the control state information of the first controller according to the switched state of the controlled object controlled by the first controller; the control state information of the first controller is used for the internet of things gateway or the second controller to determine the state of the controlled object controlled by the first controller.
And the first controller determines the control state information of the first controller according to the switched state of the controlled object and broadcasts the control state information.
For example, the controlled object of the first controller is the intelligent electric lamp 1, and the switched state is the on state; the control state information of the first controller can be that the intelligent electric lamp 1 is turned on; the first controller broadcasts the control state information, so that after the internet of things gateway or the second controller receives the control state information of the first controller, the current state of the intelligent electric lamp 1 is determined according to the control state information.
In some embodiments, a first controller obtains a current state of an internet of things device controlled by the first controller at preset time intervals; and determining control state information of the first controller according to the current state of the Internet of things equipment, and broadcasting the control state information.
Optionally, the internet of things gateway is a LoRaWAN communication gateway; and/or the controlled object of the first controller and the controlled object of the second controller at least comprise: an intelligent electric lamp.
In practical applications, the LoRaWAN communication gateway, the first controller, and the second controller may communicate based on the LoRaWAN communication protocol.
Therefore, by applying the characteristics of flexible networking, large-scale coverage and the like of the LoRaWAN communication protocol, the network coverage of a large space is realized, the control range of the Internet of things gateway is expanded, and the method is more suitable for remote control of the Internet of things equipment in the large space range.
In some embodiments, the control relationship between the controller and its associated internet of things device comprises: one-to-one control, one-to-many control, or many-to-one control; for example, the first controller controls the intelligent electric lamp 1 to be turned on or off, and the second controller controls the intelligent electric lamp 2 to be turned on or off; or the first controller controls the intelligent electric lamps 1-5 to be turned on or off, and the second controller controls the intelligent electric lamps 6-10 to be turned on or off; or the first controller and the second controller can both control the intelligent lighting 1 to be turned on or turned off.
It should be noted that before the internet of things devices are controlled by the controllers, the controllers are allocated to the respective internet of things devices, so as to clarify the controlled objects controlled by each controller.
Allocating a controller to each piece of internet-of-things equipment may refer to binding a controller identifier with an equipment identifier of the corresponding internet-of-things equipment, and establishing a mapping relationship between the controller and the internet-of-things equipment.
And if the control relationship between the controller and the related Internet of things equipment is one-to-one control, the controller identifier and the control object identifier are in one-to-one correspondence. And the first controller can determine the equipment of the Internet of things to be controlled according to the controller identifier in the first control instruction.
For example, a first controller controls the smart lamp 1, a second controller controls the smart lamp 2; when the first controller monitors a first control instruction, the first control instruction is a starting instruction for the intelligent electric lamp 2; the first controller monitors control state information of a second controller corresponding to the controller identifier in the first control instruction, and determines the current state of the intelligent electric lamp 2 according to the control state information; and if the control state information indicates that the intelligent electric lamp 2 is in the off state, the first controller broadcasts the first control instruction so that the second controller receives the first control instruction to control the intelligent electric lamp 2 to be turned on.
If the control relationship between the controller and the internet of things equipment related to the controller is one-to-many control, the first controller needs to determine the controller to which the control object indicated by the first control instruction belongs according to the controller identifier in the first control instruction; if the controller is the second controller; and monitoring control state information sent by a second controller, and broadcasting the first control instruction when determining that the first state of at least one piece of Internet of things equipment is not matched with the second state indicated by the first control instruction.
For example, after the first controller listens to the first control command, the first control command is a turn-off command for the smart lamps 6-10. Determining that the controller indicated by the first control instruction is a second controller according to the controller identifier in the first control instruction; the first controller monitors the control state information sent by the second controller, and determines that the intelligent electric lamp 10 is in an on state and the intelligent electric lamps 6-9 are in an off state according to the control state information; the first controller broadcasts the first control instruction, so that the second controller receives the first control instruction and controls the intelligent electric lamp 10 to be turned off.
If the control relationship between the controller and the related internet of things equipment is many-to-one control, the first controller and the second controller can both control the same internet of things equipment.
And after the first controller receives the first control instruction, controlling the Internet of things equipment indicated by the first control instruction according to the control object identification carried in the first control instruction and the indication information of the state to be presented of the control object. The first controller listens to the control state information of the second controller; according to the control state information, determining that the first state of the Internet of things equipment indicated by the control state information is not matched with the second state of the Internet of things equipment indicated by the first control instruction, and broadcasting the first control instruction by the first controller.
