Detailed Description
For further explanation of the technical scheme of the present invention, the following is described in detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the communication method of the internet of things device of the present invention is implemented by an internet of things system, which includes a client 2, a main gateway 1 connected to the client 2 via a communication network 100, a plurality of sub-gateways 11, and at least one internet of things device 12 connected to each sub-gateway 11.
The following will describe embodiments of the communication method of the internet of things device implemented by the internet of things system according to the present invention with reference to the accompanying drawings, wherein the embodiments sequentially comprise a setup procedure, a new addition procedure, a user end control procedure, a sensing type internet of things device end control procedure, and an operation type internet of things device end control procedure.
Referring to fig. 2, the establishment procedure describes how to establish the connection between each sub-gateway 11 and the main gateway 1, and how to establish the correspondence between each sub-gateway 11 and the devices 12, and includes a step 301, a step 302, a step 303, a step 304, and a step 305. Since the connection of each sub-gateway 11 is similar to the corresponding relationship, only a single sub-gateway 11 will be described in the following description.
In step 301, the sub-gateway 11 broadcasts a broadcast message including a sub-gateway identifier and a sub-gateway network co-address, wherein the sub-gateway identifier and the sub-gateway network co-address correspond to the sub-gateway 11, and the broadcast message further includes other basic messages, such as manufacturer name corresponding to the sub-gateway 11, software/hardware version number corresponding to the sub-gateway 11, and so on.
In step 302, when the main gateway 1 receives the broadcast message, the main gateway 1 transmits a main gateway network co-address and an ip device request to the sub-gateway 11, and it should be noted that the main gateway 1 also transmits a plurality of basic messages, such as manufacturer name of the main gateway 1, software and hardware version number of the main gateway 1, etc., to the sub-gateway 11.
In step 303, when the sub-gateway 11 receives the master gateway network co-address, the sub-gateway 11 establishes a connection with the master gateway 1 according to the master gateway network co-address.
In step 34, when the sub-gateway 11 receives the request for the yoke device, the sub-gateway 11 generates and transmits a reply message including the device information of each yoke device 12 connected thereunder to the main gateway 1. Each device information includes a device identification code, a device function type, and a device status of the corresponding internet of things device 12.
It should be noted that each device function type includes a sensing function related to sensing an environmental state, and an operation function related to starting an operation, for example, an internet of things device of the sensing function, such as an aerosol detector or a sun detector, which can sense the environmental state; the operation-type function of the internet of things device is, for example, but not limited to, an intelligent bulb or an intelligent gardening watering device. Each device state represents an operational state of the Internet of things device 12, for example, the device state of an intelligent light bulb may be an on state emitting light and an off state not emitting light.
In the step 305, when the main gateway 1 receives the reply message, the main gateway 1 stores the sub-gateway identifier of the sub-gateway 11, the correspondence between the sub-gateway identifier of the sub-gateway 11 and the device information of each of the devices 12 connected under the sub-gateway 11, and the device information of each of the devices 12, in this embodiment, the main gateway stores the sub-gateway identifier, the device identifier of the sub-gateway and the device information of the devices 12 connected under the sub-gateway, for example, the device identifier and the device information of the smart light bulb in a device list, wherein the device list records that the device identifier of the smart light bulb is 55667788, the sub-gateway identifier corresponding to the device identifier 55667788 of the smart light bulb is 11223344, the device function type of the device identifier of the device connected under the sub-gateway is 55667788, and the device state of the device connected under the device is turned off.
Referring to fig. 3, the new procedure illustrates how an object to be connected 12 establishes a connection with one sub-gateway 11 to be connected among the sub-gateways 11, and includes a step 401, a step 402, and a step 403. In step 401, the to-be-connected thing networking device 12 broadcasts a request for adding a device status corresponding to the to-be-connected thing networking device according to a new device identification code and a new device function type corresponding to the to-be-connected thing networking device 12. In step 402, when one of the sub-gateways 11 to be connected sub-gateway 11 receives the join request, the sub-gateway 11 to be connected authenticates the to-be-connected device 12, wherein the join request is encrypted in an encryption manner, and the sub-gateway 11 to be connected stores an encryption protocol for determining whether the encryption manner of the join request is correct, for example, the sub-gateway 11 to be connected confirms whether the join request conforms to the encryption manner with an encryption key. When the to-be-connected sub-gateway 11 determines that the encryption mode of the join request is incorrect, the new process is ended, and when the to-be-connected sub-gateway 11 determines that the encryption mode of the join request is correct, the to-be-connected sub-gateway 11 successfully authenticates the to-be-connected internet of things device 12, and the flow proceeds to step 403.
In step 403, the sub-gateway 11 establishes a connection with the to-be-connected device 12, and stores device information of the to-be-connected device 12 according to the join request.
Referring to fig. 4, the ue control program illustrates that the ue 2 controls a target device 12 through a user input operation, and includes a step 501, a step 502, a step 503, a step 504, a step 505, a step 506, a step 507, a step 508, and a step 509.
In step 501, the ue 2 generates a control message through the user's input operation, and transmits the control message to the primary gateway 1 through the communication network 100, wherein the control message includes a target device identifier and a control command corresponding to the target device 12. For example, when a user wants to control the intelligent light bulb in the internet of things system, the user generates a control message through the user terminal 2 and transmits the control message to the main gateway 1 through the communication network 100, wherein the control message comprises a target internet of things device identification code 55667788 corresponding to the intelligent light bulb and a control command related to the internet of things device with an opening device identification code 55667788.
In step 502, when the main gateway 1 receives the control message, the main gateway 1 obtains a target sub-gateway identifier corresponding to the target sub-gateway identifier according to the target sub-gateway identifier. It should be noted that, in the present embodiment, the main gateway 1 obtains a target sub-gateway identifier corresponding to the target device identifier according to the target device identifier and the device list, taking the target device identifier 55667788 as an example, the main gateway 1 obtains the sub-gateway identifier corresponding to the target device identifier 55667788 according to the target device identifier and the device list, and the sub-gateway identifier is 11223144.
In step 503, the main gateway forwards the control message to a target sub-gateway 11 corresponding to the target sub-gateway identification code according to the target sub-gateway identification code.
In step 504, when the target sub-gateway 11 receives the control message, the target sub-gateway 11 generates a control signal according to the control message and transmits the control signal to the target device 12 corresponding to the target device identifier according to the target device identifier. For example, the target sub-gateway 11 generates an on control signal according to the control message associated with the Internet of things device having an on device identifier 55667788, and transmits the on control signal to the intelligent light bulb according to the target Internet of things device identifier 55667788.
In the step 505, when the target device 12 receives the control signal, the target device 12 changes its own status according to the control signal, and generates and transmits a status data to the target sub-gateway 11 corresponding to the target device 12, wherein the status data includes the target device identifier corresponding to the target device 12 and a status signal corresponding to its own status. For example, when the intelligent light bulb receives the control signal, the intelligent light bulb is switched to the on state according to the control signal and transmits a state data to the target sub-gateway 11, wherein the state data includes the device identifier 55667788 and a state signal indicating that the device state of the internet of things device corresponding to the device identifier 55667788 is the on state.
In step 506, when the target sub-gateway 11 receives the status data, the target sub-gateway 11 generates and transmits a status message including the target sub-gateway identifier and the status signal to the main gateway 1 according to the target sub-gateway identifier and the status signal of the target sub-gateway 12. For example, when the target sub-gateway 11 receives the status signal transmitted by the smart lamp, the target sub-gateway generates and transmits a status message including the target device identification code of the smart lamp and associated with the smart lamp being in the on state to the main gateway 1.
In step 507, when the master gateway 1 receives the status message, the master gateway 1 transmits the status message to the client 2.
On the other hand, in the step 508, when the master gateway 1 receives the status message, the master gateway 1 updates the device status corresponding to the device information of the target object device 12 according to the status message. For example, when the main gateway 1 receives the status message related to the smart lamp, the main gateway 1 updates the device status of the smart lamp to be on according to the status message.
In step 509, when the status message is sent to the ue 2, the status message indicates the device status of the target device 12 at the ue 2. For example, when the status message related to the smart lamp is sent to the user terminal 2, the status message indicates to the user terminal 2 that the smart lamp is turned on.
For example, the main gateway 1 is connected to a first target sub-gateway 11, a second target sub-gateway 11, and a third target sub-gateway 11, the first target sub-gateway 11 is connected to a first target gateway 12, wherein the first target gateway 12 is an intelligent curtain, similarly, the second target sub-gateway 12 and the third target sub-gateway 12 are respectively connected to an intelligent curtain, when a user wants to simultaneously open the intelligent curtains, the user generates a control message associated with opening the intelligent curtains through its use terminal 2, at which time the user transmits the control message to the main gateway 1 through the communication network 100, wherein the control message includes the target gateway identifier of the intelligent curtains, and a control command associated with opening the target gateway 12 corresponding to the target gateway identifier, when the main gateway 1 receives the control signal, the main gateway 1 obtains the control message corresponding to the target gateway identifier according to the target gateway identifier, the first gateway 11, the control message corresponding to the target gateway 11, and the control message corresponding to the target gateway 11 when the control signal corresponding to the target gateway 11 is received, the control message corresponding to the target gateway 11, the control message corresponding to the target gateway identifier is obtained according to the target gateway identifier, and the control message corresponding to the target gateway identifier of the target gateway 11 when the control signal corresponding to the target gateway 11 is received, the second target sub-gateway 11 and the third target sub-gateway 11 respectively transmit the control signals to the intelligent curtains connected to the second target sub-gateway 11 and the third target sub-gateway 11, and when the intelligent curtains receive the control signals, the intelligent curtains switch to an on state according to the control signals received by the intelligent curtains and respectively transmit a state data including a corresponding target device identifier and a state signal to the first target sub-gateway 11, the second target sub-gateway 11 and the third target sub-gateway 11, wherein the state signal indicates that the intelligent curtains are on state, and when the first target sub-gateway 11 receives the state data, the first target sub-gateway 11 generates and transmits a state message including the target device identifier of the intelligent curtains and associated with the intelligent curtains to the main gateway 1 according to the state data, and similarly, when the second target sub-gateway 11 and the third target sub-gateway 11 respectively transmit the state messages to the main gateway 1 and the main gateway 1, the state message is transmitted to the main gateway 1 by the main gateway, and on the other side when the state message is transmitted by the first target gateway 11 to the main gateway 1.
Referring to fig. 5, the sensing type thing device control program illustrates how a sensing type thing device 12 having a device function type belonging to a sensing type function changes a device state of the sensing type thing device 12 having a device function type belonging to an operation type function and corresponding to the sensing type thing device, and includes a step 601, a step 602, a step 603, a step 604, a step 605, a step 606, a step 607, a step 608, a step 609, and a step 610.
It should be noted that the user terminal generates and transmits at least one determination rule to the main gateway 1 through the user's input operation, so that the main gateway 1 stores the at least one determination rule in advance, wherein each determination rule has a condition part including a device identification code of a sensing type thing networking device 12 having a device function type belonging to a sensing type function and a control part including a device identification code of an operation type thing networking device 12 corresponding to the sensing type thing networking device and having a device function type belonging to an operation type function, and a trigger condition for judging whether a sensing signal of the sensing type thing networking device 12 meets a condition state, and a control action for indicating control of the operation type of the Internet of things 12, for example, a sun detector belonging to the sensing type of Internet of things 12 having a device identification code of 11335577, an intelligent window curtain belonging to the operation type of Internet of things 12 having a device identification code of 22446688, the condition part of the determination rule related to the sun detector and the intelligent window curtain including the device identification code 11335577, the triggering condition being that a detection value transmitted by the Internet of things having a device identification code of 11335577 is higher than a predetermined threshold, the control part including the device identification code 22446688, the control action being to place the Internet of things having a device identification code of 22446688 in a sunshade state.
In the step 601, the sensing type of the device 12 generates and transmits a sensing data to a sub-gateway 11 (hereinafter referred to as a first sub-gateway 11) corresponding to the sensing type of the device 12, wherein the sensing data includes a sensing signal related to a detection value detected by the sensing type of the device 12 and a sensing type of the device identification code corresponding to the sensing type of the device 12. For example, the sunlight detector generates a sensing signal corresponding to the detected illuminance value and transmits a sensing data including the sensing signal and the device identification code 11335577 corresponding to the sunlight detector to the first sub-gateway 11 corresponding to the sunlight detector.
In step 602, when the first sub-gateway 11 receives the sensing data, the first sub-gateway 11 transfers the sensing data to the main gateway 1.
In step 603, when the main gateway 1 receives the sensing data, the main gateway 1 determines whether to generate another control message to the operation type thing networking device 12 having the device function type belonging to the operation type function and corresponding to the sensing type thing networking device according to the determination rule corresponding to the sensing type thing networking device 12 (i.e. the determination rule having the sensing type thing networking device identification code corresponding to the sensing type thing networking device 12), and ends the thing networking device end control procedure when it is determined that another control message is not required to be generated, and proceeds to step 604 when it is determined that another control message is required to be generated to the operation type thing networking device 12. For example, when the master gateway 1 receives the sensing data, the master gateway 1 determines whether to generate another control message according to the determination rule corresponding to the device identifier 11335577, and when the master gateway 1 determines that the detection value of the internet of things device with the device identifier 11335577 is greater than the predetermined threshold, the master gateway generates another control message.
