In some embodiments, the resource device may be connected to the client through a cloud platform, for example, in the embodiment corresponding to fig. 1, both the resource devices 11 and 15 may be connected to the client 17 through the cloud platform 16, and the client 17 may perform information interaction with the resource devices 11 and 15 through the cloud platform 16. In other embodiments, the resource device may be directly connected to the client 17, for example, in the embodiment corresponding to fig. 1, the

resource devices

12 and 13 are both directly connected to the client 17, so that the client 17 may directly perform information interaction with the

resource devices

12 or 13. The client 17 performs information interaction with any resource device, which may include: the client 17 may manage and/or control the resource devices 11 to 15, such as at least one of resource device software and hardware upgrade, resource device function and/or operation status and/or resource status control, resource subscription, and resource query.

In other embodiments, any two of the above may be transmitted with other protocols for data or messaging.

It should be noted that, in the technology of internet of things, the client 17 manages resource devices in a resource form, where "resource" is an abstract concept, and may refer to a physical resource device, a model, a software/hardware version, or a manufacturer of a resource device, or a dynamic attribute such as an operation that can be executed by a resource device, an event that can be reported, a parameter, or a readable status parameter.

Fig. 2 is a schematic view of an implementation flow of a method for reporting a resource status to a client by a resource device in the related art, as shown in fig. 2, the method includes:

s201, establishing connection between the Device A and the Cloud A.

In some embodiments, the connection between Device a and Cloud a may be a long connection. Device a in the embodiment of the present application may be the above-mentioned resource Device, and Cloud a may be the above-mentioned Cloud platform.

S203, the Client A sends a request for acquiring the equipment information on the Cloud A to the Cloud A.

In some embodiments, the connection between Client a and Cloud a may be a short connection or a long connection. The Client a in the embodiment of the present application may be the Client described above. In some embodiments, data transmission is performed between the Client a and the Cloud a or between the Device a and the Cloud a after the secure connection is established, for example, the secure connection may be established by using HTTP protocol, coAP protocol, MQTT protocol, or the like, so that a secure channel may be established between the Client a and the Cloud a or between the Device a and the Cloud a, and further, data or information may be securely transmitted between the Device a and the Cloud a.

The device information may include information for all devices on Cloud a or information for devices associated with Client a. The device information may include device information of at least one device.

S205, sending the device information on the Cloud A to the Client A by the Cloud A.

The Device information on Cloud a may include Device a's Device information. In some embodiments, the Device information on Cloud a may include Device information of at least one of Device B, device C, device D, etc.

Device a may include at least one resource thereon, and a resource may include at least one resource information.

For example, when Device a is a lamp, at least one resource may be included in the lamp, for example, at least one of a resource for controlling brightness of the lamp, a resource for controlling color temperature of the lamp, a resource for controlling flicker frequency of the lamp, etc. may be included in the lamp.

For another example, when the Device a is a washing machine, the washing machine may include at least one resource, for example, at least one of a resource for controlling a washing pattern, a resource for controlling a water level height, a resource for controlling a washing time period, a resource for controlling a rinsing intensity, and the like may be included in the washing machine.

For another example, when Device a is a tv set, the tv set may include at least one resource, for example, the tv set may include at least one of a resource for controlling a playing channel of the tv set, a resource for controlling a playing sound size, a resource for adjusting a display mode, and the like.

It should be understood that Device a may also be exemplified by other devices, such as an air conditioner, a sound box, or a kettle, and the implementation scenario of Device a is not limited in the embodiments of the present application.

For example, cloud a sends device information of at least one device such as Cloud a lighting, washing machine, television, air conditioner, sound box or kettle to Client a.

The device information may include not only at least one resource included in the device or an identification of the at least one resource, but also at least one of a device type, a device identification, a device appearance, a device location, and the like.

S207, the Client A sends a subscription request to the Cloud A, and the subscription request is used for requesting to subscribe the resource information of the Device A on the Cloud A.

In some embodiments, client a may request to subscribe to resource information of one Device, or may request to subscribe to resource information of at least two devices, the resource information of one Device or at least two devices including Device a's resource information. In some embodiments, client a may request to subscribe to resource information of one resource of one device, or may subscribe to resource information of at least two resources of one device.

S209, the Cloud A sends a subscription request to the Device A, and the subscription request is used for requesting to subscribe the resource information of the Device A on the Cloud A.

S211, the Device A sends a subscription success message and current resource information to the Cloud A.

In some embodiments, the subscription success message and the current resource information may be sent in one signaling. In other embodiments, the subscription success message and the current resource information may be sent in two separate signaling, for example, the subscription success message may be sent before the current resource information, or the current resource information may be sent before the subscription success message.

S213, cloud A forwards the successful subscription message and the current resource information to Client A.

S215, changing the state of the Device A resource.

Taking the resource device as a washing machine as an example, the resource status change is at least one of an operation mode change of the washing machine, water level information of the washing machine, and a change of rinsing intensity of the washing machine, for example.

S215, the Device A sends the changed resource information to the Cloud A.

S217, cloud A sends the changed resource information to Client A.

The related art only provides a situation how the Device a reports the resource status to the Client a, and the related art does not consider how the Device a operates after power-off and restart.

For example, in an implementation scenario, when a washing machine is washing clothes in a normal washing mode, if the washing machine is powered off and on (for example, power off and on for restart, power off and on for power off, or power off and on for power off due to power failure, or power off and on due to user misoperation, etc.), the washing machine may be in a shutdown state, a standby state, or a default state.

For example, in another implementation scenario, when the washing machine performs washing in the normal mode, if the user wants to switch to the normal mode again after switching to the quick-washing mode, the user needs to perform a complicated operation to recover to the normal mode, which causes a troublesome operation for the user.

For another example, when the air conditioner detects that the ambient temperature meets the set temperature, the air conditioner may enter a power saving mode or a standby mode, however, in many scenarios, the user may want the air conditioner to operate in a fixed state all the time, and may not want the air conditioner to suddenly enter another state.

Fig. 3 is a schematic flowchart of a communication method of the internet of things provided in the embodiment of the present application, and as shown in fig. 3, the method includes:

s301, a client receives first resource information sent by resource equipment through a cloud platform; the first resource information comprises or indicates first resource status information of a particular resource in the resource device.

It should be noted that the Client described in the embodiment of the present application may be the Client 17 in fig. 1 or the Client a in another embodiment, and the resource Device described in the embodiment of the present application may be any one of the resource devices 11 to 15 in fig. 1 or the Device a in another embodiment. The Cloud platform described in the embodiment of the present application may be the Cloud platform 16 in fig. 1 or Cloud a in other embodiments.

In some embodiments, the resource device may send the resource information to the client at a fixed period through the cloud platform. In other embodiments, the resource device may send the resource information to the client at a variable period, for example, between 6. For another example, when the resource device determines that the user is present in the home, the resource information may be transmitted at a shorter period, and when the resource device determines that the user is not present in the home, the resource information may be transmitted at a longer period. The first resource information may be current resource information sent by the resource device to the client through the cloud platform.

Each resource information (which may be the resource information in the embodiment corresponding to fig. 2, including the first resource information, the second resource information, or the third resource information described in this embodiment) sent by the resource device to the client through the cloud platform may include or indicate resource state information of a specific resource, or may include or indicate resource state information of a specific resource and resource attribute information of a specific resource. The resource status information of a particular resource may be a current status value of the particular resource, and typically changes as the status of the particular resource changes. The resource attribute information in each resource information sent by the resource device to the client through the cloud platform may include at least one of: whether the resource information/resource state information is recoverable, the type of the resource information/resource state information, whether the resource information/resource state information is modifiable, the identification of the specific resource corresponding to the resource information/resource state information, and the like.

For example, the first resource information may include not only the first resource status information but also resource attribute information of a specific resource. In this embodiment, each piece of resource information, such as first resource information, second resource information, third resource information, and the like, sent by the resource device to the client through the cloud platform may include resource attribute information of a specific resource, or part of the resource information includes resource attribute information of the specific resource.

The first resource information (or the second resource information or the third resource information described below) in the embodiment of the present application may be represented by a state, and the state may represent a current state of a specific resource. For example, the state may include: resource state 1: XXX; resource state 2: XXX; resource state 3: XXX; resource attribute 1: XXX; resource attribute 2: XXX.

The first resource status information may be at least one resource status information, and each of the at least one resource status information may be a resource status value. For example, taking the resource device as a washing machine and the specific resource as an operating mode of the washing machine, the first resource status information may be at least one of an operation mode identifier of the washing machine, a time period for which the washing machine has been operated, water level information of the washing machine, washing intensity of the washing machine, and the like.

The specific resource may be one resource or at least two resources in the resource device. The resource attribute information of a specific resource may include one or at least two attribute information, at least part of which may be fixed attribute information or may be attribute information that changes with time and/or scene change, or may be attribute information that changes by the resource device receiving a user-input attribute adjustment operation. For example, when the resource attribute information is information a (or described as indication: a) under an indication (indication) attribute, the information a represents that the resource status information can be recovered. In some embodiments, the resource attribute information may always be information a. In other embodiments, the resource attribute information may be modified to information B when the resource device receives some instruction, where the information B characterizes that the resource status information is unrecoverable. In still other embodiments, when the resource device determines that the number of times the resource information is restored within a period of time is greater than a threshold, it may be determined that the restoration has failed, and the resource attribute information may be modified to B.

S303, under the condition that the first resource state information is changed into the second resource state information, the client sends a recovery request to the resource equipment through the cloud platform; the recovery request instructs the resource device to recover the state to a state corresponding to the first resource state information.

In an embodiment of the application, the second resource status information is different from the first resource status information.

In some embodiments, the client may determine that the first resource status information changes to the second resource status information. In order to ensure the effectiveness of the recovery process, the client may send the recovery request only when the first resource state information changes to other resource state information and then to the second resource state information. For example, to avoid the influence of the child false trigger on the laundry process, the client may send the recovery request to the resource device when it is determined that the first resource status information changes at least twice within a set time period.

The first resource status information may be changed into the second resource status information, and at least one of all the resource status information in the first resource status information may be changed.

In some embodiments, the client determines that the first resource status information changes into the second resource status information, which may be that the client is capable of obtaining the second resource information with the determined status value, thereby determining that the first resource status information changes into the second resource status information. In this way, the client may receive the second resource state information sent by the resource device through the cloud platform, so as to determine that the first resource state information changes into the second resource state information.

In other embodiments, the client determines that the first resource status information changes into the second resource status information, which may be that the client cannot obtain a piece of second resource information with a determined status value, and only knows that the first resource status information changes, but does not know what the first resource status information has changed. In this way, the client may receive information, which is sent by the resource device through the cloud platform and used for representing that the first resource state information changes, or the cloud platform may determine whether the first resource state information changes, and the client may receive information, which is sent by the cloud platform and used for representing that whether the first resource state information changes.

In some embodiments, the recovery request may include the first resource information, or the recovery request may include the first resource state information, in which case the resource device may not store the first resource information before the change or the first resource state information after the change in state. In other embodiments, the recovery request may include neither the first resource information nor the first resource state information, and the recovery request is only one request for indicating state recovery. Whether the first resource information is included in the recovery request may be preset, or may be flexibly determined according to different attributes of the resource device.

When the resource device receives the recovery request through the cloud platform, the resource device may respond to the recovery request, modify the current resource state information of the resource device into the first resource state information, or modify the current resource information into the first resource information, so that the state of the resource device may be recovered to the state corresponding to the first resource state information. For example, in the case where the first resource status information of the resource device changes to the second resource status information, the resource device may modify the second resource status information to the first resource status information. When the resource device restores the resource state information to the first resource state information, the resource device may operate in a state corresponding to the first resource state information.

Still taking the washing machine as an example, when the washing machine operates in the normal mode for 20 minutes, if the operation mode changes, the washing machine changes to the quick washing mode, the standby mode or the shutdown mode, after receiving the recovery request, the washing machine may re-enter the normal washing mode based on the recovery request, and continue washing for 20 minutes.

In the embodiment of the application, when the first resource state information of the resource equipment is changed into the second resource state information, the client side can restore the state of the resource equipment to the state corresponding to the first resource state information by sending the restoration request to the resource equipment, so that the resource equipment can restore the state to the previous normal working state under the condition that the state of the resource is changed due to power failure or faults of the resource equipment, and the reliability of communication of the internet of things can be improved.

Fig. 4 is a schematic flow chart of another communication method of the internet of things provided in the embodiment of the present application, and as shown in fig. 4, the method includes:

s401, the resource equipment sends first resource information to a client through a cloud platform; the method comprises the steps that a client receives first resource information sent by resource equipment through a cloud platform; the first resource information comprises or indicates first resource status information of a particular resource in the resource device.

The cloud platform is embodied at the side of the cloud platform, receives first resource information sent by the resource equipment, and sends the first resource information to the client.

S403, the client determines that the first resource state information is changed into second resource state information.

The state corresponding to the first resource state information is the state of the specific resource before the resource equipment is powered off, and the state corresponding to the second resource state information is the state of the specific resource after the resource equipment is powered on.

After S403, the client may also determine that the resource state of the specific resource can be restored, and then perform S405 again. In some embodiments, the first resource information further includes or indicates resource attribute information of the particular resource, the resource attribute information being used to indicate that the resource state of the particular resource is recoverable; the client may determine that the resource state of the particular resource can be restored based on the resource attribute information.

S405, the client sends a recovery request to the resource equipment through the cloud platform; and the resource equipment receives a recovery request sent by the client through the cloud platform.

The cloud platform is embodied at the side of the cloud platform, receives the recovery request sent by the client and sends the recovery request to the resource equipment.

S407, the resource device restores the state to the state corresponding to the first resource state information.

The resource device may restore the state to a state corresponding to the first resource state information in response to the restore request.

In the embodiment of the application, when the resource equipment is abnormal, the resource state of the resource in the resource equipment can be reset, so that the reliability of the communication of the internet of things can be improved. In addition, the client and the resource equipment are communicated in a cloud platform communication mode, and the cloud platform can be accessed to a large number of clients and resource equipment, so that the Internet of things system has the advantages of strong system expansibility and wide application range.

Fig. 5 is a schematic flow chart of another communication method of the internet of things provided in the embodiment of the present application, and as shown in fig. 5, the method includes:

s501, sending first resource information to a cloud platform by a resource device; the cloud platform receives first resource information sent by the resource equipment.

In this embodiment, the first resource information may include or indicate not only the first resource state information of a specific resource in the resource device, but also resource attribute information of the specific resource, where the resource attribute information is used to indicate that the resource state of the specific resource can be recovered.

In some embodiments, the cloud platform may determine, after receiving the first resource information, that the resource state of the particular resource is recoverable based on the resource attribute information of the first resource information.

In some embodiments, the cloud platform may modify the third resource information stored in the cloud platform into the first resource information; the third resource information is received by the cloud platform before the first resource information.

S503, the cloud platform sends first resource information to the client; the client receives first resource information sent by the cloud platform.

In some embodiments, the protocol on which the cloud platform and the resource device communicate may be the same as the protocol on which the cloud platform and the client communicate, for example, both protocols are HTTP protocol, coAP protocol, or MQTT protocol. In other embodiments, the protocol based on which the cloud platform and the resource device communicate may be different from the protocol based on which the cloud platform and the client communicate, for example, the former may be an HTTP protocol, and the latter may be a CoAP protocol, which is not limited in this embodiment of the present application.

After the client receives the first resource information, a state corresponding to the first resource state information may be displayed.

In some embodiments, the client or the cloud platform may determine the readable and writable attribute and/or the recoverable attribute of the resource according to resource attribute information that indicates whether the resource status is recoverable and is reported by the resource device. For example, the working mode resource of the washing machine has an index attribute (read-only attribute) and a working mode attribute (read-write attribute); the indication attribute indicates whether the working mode resource state can be recovered; and after the equipment reports the resource, the client judges whether the attribute state of the resource is recoverable according to the index attribute value.

And S505, changing the first resource state information in the resource equipment into second resource state information.

In an operation scene of a resource device, a situation that the resource device is powered off and powered on often occurs. In one embodiment, after the resource device is powered on, the state of the resource device does not return to the state before the power failure, but enters the initial state set by the resource device.
