[0028] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity and clarity, the description in the following text describes the components and settings of specific examples. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to the numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.

[0030] The embodiments of the present application provide a device state reporting system. As shown in FIG. 1, a structural schematic diagram of a device state reporting system according to an embodiment of the present application is shown. Figure 1

[0031] The device state reporting system comprises an Internet of Things device, a central control device, a state reporting device and a cloud server; wherein the Internet of Things device, the central control device and the state reporting device are connected to the same local area network, and the cloud server is connected to the Internet.

[0032] ​Further, the local area network includes, but is not limited to, a local area network composed of Internet of Things devices in a family, a local area network composed of Internet of Things devices in a building. The central control device can be a separately arranged device, or one of the Internet of Things devices in the local area network can be selected as the central control device.

[0033] Further, the types of state reporting devices include communication modules and user terminals. The types of communication modules include, but are not limited to, WiFi modules, routers, and network access point devices. The communication modules are used to build a local area network, and in one local area network, at least one central control device is included, and each central control device corresponds to at least one Internet of Things device. In order to make the embodiments of the present application easier to understand, the following describes a case of one local area network, and for the case of multiple local area networks, other local area networks can refer to the embodiments of the present application to perform reporting of device states.

[0034] The central control device determines the device state of the Internet of Things device by polling the Internet of Things device in the local area network, detects the network connection state between the local area network and the Internet, determines the state reporting device corresponding to the network connection state, and sends the device state of the Internet of Things device to the state reporting device, so that the state reporting device reports the device state of the Internet of Things device to the cloud server in the Internet.

[0035] The cloud server receives the device state of the Internet of Things device reported by the state reporting device, wherein the device state of the Internet of Things device is sent by the central control device in the local area network to the state reporting device, determines the network connection state between the local area network and the Internet, and updates the historical device state corresponding to the Internet of Things device according to the device state of the Internet of Things device and the network connection state.

[0036] Further, the types of network connection states include a disconnected state and a normal connection state. The disconnected state indicates that the local area network and the Internet have been disconnected. The normal connection state indicates that the connection between the local area network and the Internet is normal.

[0037] Further, the state reporting device is a communication module or a user terminal in the local area network. The user terminal can communicate with the cloud server in the Internet through a data network. The communication module is used to connect the local area network and the Internet, and can directly communicate with the cloud server through the Internet. When the network connection state is the disconnected state, the state reporting device is the user terminal. When the network connection state is the normal connection state, the state reporting device is the communication module.

[0038] In the embodiment of the present application, the central control device constructs a distributed system, and determines the device states of the Internet of Things devices by polling and reports the device states of the Internet of Things devices in a centralized manner, which can avoid the problem of excessive polling pressure of the cloud server caused by polling a large number of Internet of Things devices, reduce the polling pressure of the server, and shorten the polling time of the cloud server. Further, in order to avoid the problem of disconnection between the local area network and the Internet where the cloud server is located, the device state of the Internet of Things device can be reported to the cloud server through the communication module when the network connection state between the local area network and the Internet is a normal connection state, and the device state of the Internet of Things device can be reported to the cloud server through the user terminal when the network connection state between the local area network and the Internet is a disconnected state, based on which the normal updating of the device state of the Internet of Things device in the cloud server can be ensured.

[0039] The steps performed by the central control device and the cloud server are described below.

[0040] The embodiment of the present application provides a device state reporting method performed by a central control device. As shown in Figure 2 The flowchart of the device state reporting method performed by the central control device according to an embodiment of the present application is shown in

[0041] In step S210, the device state of the Internet of Things device is determined by polling the Internet of Things device in the local area network.

[0042] The central control device and each Internet of Things device can form a local area network after connecting to the communication module respectively; the central control device can establish a network connection with each Internet of Things device in the local area network, and poll each Internet of Things device to determine the device state of each Internet of Things device.

[0043] The types of device states include online state and offline state. The Internet of Things device in the online state indicates that the Internet of Things device can receive and execute the control instruction issued by the cloud server. The Internet of Things device in the offline state indicates that the Internet of Things device cannot receive and execute the control instruction issued by the cloud server.

[0044] Specifically, the time length of the secondary heartbeat period is set in advance. The central control device can send a secondary heartbeat packet to one of the Internet of Things devices at the arrival of each secondary heartbeat period; if a secondary response packet returned by the Internet of Things device is received in the secondary heartbeat period, it is determined that the device state of the Internet of Things device is in the online state; if the secondary response packet returned by the Internet of Things device is not received in the secondary heartbeat period, it is determined that the device state of the Internet of Things device is in the offline state.

[0045] In step S220, the network connection state between the local area network and the Internet is detected.

[0046] The kind of network connection state includes: a disconnected state and a normal connection state.

[0047] The disconnected state indicates that the local area network and the Internet are disconnected, that is, the communication module and the cloud server have been disconnected and cannot communicate. In the embodiment of the application, in the disconnected state, that is, in the case that the local area network and the Internet are disconnected, the communication module can work normally. In the disconnected state, the communication module can work normally, which may be caused by the problem that the communication module cannot connect to the Internet due to the loosening of the network cable.

[0048] The normal connection state indicates that the local area network and the Internet are normally connected, that is, the connection between the communication module and the cloud server is normal and has not been disconnected, and communication can be carried out normally.

[0049] Specifically, the central control device can send a network connection state inquiry message to the communication module, and receive a network connection state response message returned by the communication module, wherein the network connection state carried in the network connection state response message is the disconnected state or the normal connection state. Alternatively, in the case that the network connection state is the normal connection state, the central control device can receive a first heartbeat packet sent by the cloud server through the communication module every preset time period. If the first heartbeat packet sent by the cloud server through the communication module is not received, it is determined that the network connection state is the disconnected state. If the first heartbeat packet sent by the cloud server through the communication module is received, it is determined that the network connection state is the normal connection state.

[0050] Step S230: determining a state reporting device corresponding to the network connection state.

[0051] If the network connection state is the disconnected state, a communication connection is established with a user terminal accessing the local area network, and the user terminal is determined as the state reporting device.

[0052] If the network connection state is the normal connection state, the communication module used to connect the local area network and the Internet is determined as the state reporting device.

[0053] Step S240: sending a device state of the Internet of Things device to the state reporting device, so that the state reporting device reports the device state of the Internet of Things device to the cloud server in the Internet.

[0054] If the state reporting device corresponding to the network connection state is a user terminal, the device state of the Internet of Things device is sent to the user terminal, so that the user terminal reports the device state of the Internet of Things device to the cloud server through a data network.

[0055] If the network connection state corresponds to a state reporting device of the communication module, after receiving the first heartbeat packet from the cloud server forwarded by the communication module, the device state of the Internet of Things device is sent to the communication module, so that the communication module reports the device state of the Internet of Things device to the cloud server through the Internet.

[0056] In the embodiment of the application, the Internet of Things device in the local area network where the control device is located can be multiple. The control device can send the device state corresponding to each of the multiple Internet of Things devices to the state reporting device, so that the state reporting device reports the device state corresponding to each of the multiple Internet of Things devices to the cloud server. Alternatively, the control device can send the device state corresponding to the Internet of Things device with device state switching among the multiple Internet of Things devices to the state reporting device, so that the state reporting device reports the device state corresponding to the Internet of Things device with device state switching to the cloud server. The device state switching refers to the device state of the Internet of Things device switching from the offline state to the online state, or switching from the online state to the offline state.

[0057] Further, the control device can store the device state corresponding to each of the Internet of Things devices determined in the previous polling; determine the Internet of Things device with device state switching according to the device state corresponding to each of the Internet of Things devices determined in the previous polling and the device state corresponding to each of the Internet of Things devices determined in the current polling; and send the device state corresponding to each of the Internet of Things devices with device state switching to the state reporting device, so that the state reporting device reports the device state corresponding to each of the Internet of Things devices with device state switching to the cloud server.

[0058] In the embodiment of the application, the control device can generate a device state list; the device state list is used to record the device state corresponding to each of the multiple Internet of Things devices or the device state of the Internet of Things device with device state switching among the multiple Internet of Things devices; and the control device can send the device state list to the state reporting device, so that the state reporting device reports the device state list to the cloud server.

[0059] In the embodiment of the application, since the control device can be a device separately arranged in the local area network or an Internet of Things device in the local area network, when the control device determines the device state of the Internet of Things device by polling the Internet of Things device in the local area network, the control device can determine the device state of the control device itself and report the device state of the control device itself to the cloud server through the state reporting device together with the device state of the other Internet of Things devices; and after receiving the device state of the control device, the cloud server can update the device state information corresponding to the control device.

[0060] In the embodiment of the present application, the central control device determines the device status of the Internet of Things device in the local area network by polling the Internet of Things device, detects the network connection state between the local area network and the Internet, determines the state reporting device corresponding to the network connection state, and sends the device status of the Internet of Things device to the state reporting device, so that the state reporting device reports the device status of the Internet of Things device to the cloud server in the Internet. The central control device in the embodiment of the present application polls the device status of each Internet of Things device and uses the state reporting device corresponding to the current network connection state to report the cloud server in a centralized manner. The cloud server can obtain the device status of each Internet of Things device in the local area network in which the central control device is located by polling the central control device, without polling a large number of Internet of Things devices, thereby reducing the polling pressure of the cloud server and shortening the polling time of the cloud server.

[0061] Based on the above-mentioned reporting method of the device status performed by the central control device, the embodiment of the present application further provides a reporting method of the device status performed by the cloud server. As shown in Figure 3 the flowchart of the reporting method of the device status performed by the cloud server according to an embodiment of the present application.

[0062] In step S310, the device status of the Internet of Things device reported by the state reporting device is received; wherein the device status of the Internet of Things device is sent by the central control device in the local area network to the state reporting device.

[0063] The state reporting device can be a user terminal or a communication module connected to the local area network.

[0064] In the embodiment of the present application, the cloud server can receive the device status corresponding to each of a plurality of Internet of Things devices in the local area network or the device status corresponding to an Internet of Things device having a device status switch in the plurality of Internet of Things devices reported by the state reporting device.

[0065] Further, the cloud server can receive a device status list reported by the state reporting device; the device status request is used to record the device status corresponding to each of a plurality of Internet of Things devices or the device status of an Internet of Things device having a device status switch in the plurality of Internet of Things devices.

[0066] In step S320, the network connection state between the local area network and the Internet is determined.

[0067] In one way, the cloud server can determine the network connection state by identifying the type of the state reporting device. Specifically, if it is determined that the state reporting device is a user terminal connected to the local area network, it is determined that the network connection state is a disconnected state. If it is determined that the state reporting device is a communication module for connecting the Internet and the local area network, it is determined that the network connection state is a normal connection state.

[0068] In another way, the cloud server can poll the central control device and the Internet of Things device through the Internet to determine the network connection state. This way will be described later, so it is not described again.

[0069] In step S330, the device state information corresponding to the Internet of Things device is updated according to the device state of the Internet of Things device and the network connection state.

[0070] The device state information at least includes the following information: the device state of the Internet of Things device and the device state reporting source information. The device state reporting source information is the device information of the state reporting device or the network connection state.

[0071] The cloud server stores the device state information corresponding to the Internet of Things device in the storage space; updates the stored device state of the Internet of Things device according to the device state of the Internet of Things device received this time; and updates the device state reporting source information of the Internet of Things device according to the network connection state this time.

[0072] In the embodiment of the application, after the cloud server updates the device state information corresponding to the Internet of Things device, the cloud server can send the device state of the Internet of Things device to the user terminal, so that the user can view the device state of the Internet of Things device through the user terminal.

[0073] In the embodiment of the application, the cloud server receives the control parameter information of the Internet of Things device sent by the user terminal, generates the control instruction of the Internet of Things device according to the control parameter information, queries the device state information of the Internet of Things device, determines the device state of the Internet of Things device as online according to the device state information, determines the instruction issuing device according to the device state reporting source information of the Internet of Things device, sends the control instruction to the Internet of Things device through the instruction issuing device, and the control parameter information is used to adjust the operating parameter of the Internet of Things device. In the case where the device state of the Internet of Things device is determined as offline according to the device state information, the Internet of Things device has been offline notification is sent to the user terminal.

[0074] Further, the control instruction is sent to the Internet of Things device through the instruction issuing device, which includes: the control instruction is sent to the instruction issuing device, so that the instruction issuing device directly sends the control instruction to the Internet of Things device, or the instruction issuing device sends the control instruction to the central control device, and the central control device sends the control instruction to the Internet of Things device.

[0075] Further, when the device state reporting source information is the communication module or the normal connection state, the communication module is determined as the instruction issuing device, and the control instruction is sent to the Internet of Things device through the communication module; when the device state reporting source information is the user terminal or the disconnection state, the user terminal is determined as the instruction issuing device, and the control instruction is sent to the Internet of Things device through the user terminal.

[0076] For example, a user wants to adjust the refrigeration temperature of an air conditioner, and adjusts the refrigeration temperature of the air conditioner to 20℃ in the user terminal. The user terminal can send the information (control parameter information) that the refrigeration temperature of the air conditioner is adjusted to 20℃ to the cloud server. The cloud server generates a control instruction according to the control parameter information and queries the device state information corresponding to the air conditioner. If the device state of the air conditioner is an online state, and the device state reporting source information is the communication module, the control instruction is sent to the air conditioner through the communication module.

[0077] The process of determining the network connection state by polling the central control device and the Internet of Things device is described below. As shown in FIG. 6, it is a step flow chart of determining the network connection state according to an embodiment of the present application. Figure 4

[0078] In step S410, a first heartbeat packet is sent to the central control device in the local area network through the communication module.

[0079] In step S420, it is determined whether a first response packet returned by the central control device through the communication module is received. If yes, step S430 is performed; if no, step S440 is performed.

[0080] In step S430, if the first response packet returned by the central control device is received, it is determined that the network connection state is a normal connection state.

[0081] In step S440, if the first response packet returned by the central control device is not received, a second heartbeat packet is sent to the Internet of Things device through the communication module.

[0082] If the central control device corresponds to multiple Internet of Things devices, the second heartbeat packet is sent to the multiple Internet of Things devices through the communication module respectively. Further, the second heartbeat packet can be sent to the multiple Internet of Things devices through the communication module respectively in a polling manner.

[0083] In step S450, it is determined whether a second response packet returned by the Internet of Things device through the communication module is received. If yes, step S460 is performed; if no, step S470 is performed.

[0084] ​Step S460: If a secondary response packet is received from the IoT device through the communication module, the IoT device in the local area network is polled through the communication module to determine the device status of the IoT device and update the device status information corresponding to the IoT device.

[0085] If a secondary response packet is received from an IoT device, it means that the local area network and the Internet can communicate normally, but the central control device fails. You can temporarily bypass the central control device and poll each IoT device in the local area network to determine the device status of each IoT device and update the device status information of each IoT device.

[0086] Types of central control device failures include: the central control device is damaged, the central control device is reset and network configuration has not yet been completed. After the central control device failure is eliminated, the central control device can normally receive the secondary response packet returned by the communication module.

[0087] In this case, the device status reporting source information in the device status information may be the communication module or the normal connection status.

[0088] Step S470: If the secondary response packet returned by the IoT device through the communication module is not received, it is determined that the network connection state is a disconnected state.

[0089] If no secondary response packet is received from the IoT device, it indicates that the local area network and the Internet cannot communicate normally. Furthermore, if the central control device corresponds to multiple IoT devices, if no secondary response packet is received from the multiple IoT devices via the communication module, the network connection state is determined to be disconnected.

[0090] In order to make the embodiments of the present application easier to understand, the device status reporting method of the embodiments of the present application is described below in conjunction with specific smart home application scenarios.

[0091] like Figure 5 , which is a schematic diagram of a smart home application scenario according to an embodiment of the present application.

[0092] In the smart home application scenario, the device status reporting system includes: cloud server, WiFi module (i.e. communication module), user terminal, home host (i.e. central control device) and Internet of Things device (i.e. Internet of Things device).

[0093] A communication module is used to establish a local area network (LAN), which includes at least one central control device. Each central control device corresponds to at least one IoT device. Furthermore, in a smart home application scenario, the WiFi module, each home host, and each IoT device corresponding to each home host are connected to the same LAN.

[0094] In the smart home application scenario, the Internet of Things device supports WiFi protocol, Message Queuing Telemetry Transport (MQTT) protocol, Bluetooth Low Energy (BLE) protocol for communication, and can be normally configured and controlled through the application program (APP) of the user terminal and the instruction is issued. The home host can normally communicate with the Internet of Things device, and the home host has the right to report the device status of the Internet of Things device to the cloud server. The home host and all Internet of Things devices can be configured through the WiFi module and can view the device information through the APP.

[0095] In the case of normal WiFi module, the WiFi module can normally connect to the local area network and the Internet, so that all devices can normally connect to the Internet.

[0096] In the case of normal WiFi module, the device status of the home host and the device status of other Internet of Things devices are pushed by the home host. Specifically, because the cloud server checks whether the Internet of Things device is online through polling, when the number of Internet of Things devices is too large, the cloud server sends a first heartbeat packet to each Internet of Things device, which is too large in pressure and has a large time cost in waiting for the first response packet returned by each Internet of Things device. The embodiment of the application uses the home host to build a distributed system, uses the home host as a key node in the distributed system, and uses the home host to poll the device status of each Internet of Things device and store it in the storage space of the home host. When the Internet of Things device, the home host and the WiFi module can normally access the Internet, the polling message (first heartbeat packet) of the cloud server will be sent to the home host through the WiFi module, and the home host will report the device status of the Internet of Things device stored in the storage space to the cloud server, so that the cloud server updates the device status information of the Internet of Things device using the received device status of the Internet of Things device. After the cloud server completes the update, it can send the updated device status of the Internet of Things device to the user terminal, so that the user can view the current device status of the Internet of Things device. Further, in order to improve the reporting efficiency, the home host can only report the device status of the Internet of Things device whose device status has changed to the cloud server through the WiFi module.

[0097] In the case of WiFi module exception, the WiFi module cannot normally connect to the local area network and the Internet, and the local area network and the Internet are disconnected, so that all devices in the local area network cannot connect to the Internet. Further, the WiFi module exception can be caused by the disconnection of the network cable of the WiFi module, etc. The WiFi module can normally work, but cannot connect to the Internet. At this time, the WiFi module, the home host and the Internet of Things device corresponding to the home host form a local area network.

[0098] In the case of WiFi module exception, the home host and the Internet of Things device can normally communicate with the WiFi module. At this time, the home host can be used as an offline home host, and the home host and the Internet of Things device can communicate through the BLE protocol. When the home host and the Internet of Things device can normally communicate, the home host marks the device state of the Internet of Things device in the device state list as "online", but at this time, since the cloud server does not receive the first level response packet pushed by the key node (the home host), the cloud server will traverse the Internet of Things devices under the home host respectively, that is, poll each Internet of Things device corresponding to the central control device. If no response packet is received, these Internet of Things devices can be marked as "offline" first. At this time, if the user terminal accesses the local area network, when the user opens the preset APP in the user terminal, the user terminal can establish a communication connection with the home host through offline authentication, and the home host reports the device state of the Internet of Things device stored in the storage space to the user terminal. The user terminal uses mobile phone traffic to report the device state of the Internet of Things device to the cloud server, and the cloud server marks the device data of this type, that is, the user terminal reports the device state of the Internet of Things device because the WiFi module cannot connect to the Internet, and the device state of the Internet of Things device is reported through data traffic. Further, in order to improve the reporting efficiency, the home host can only report the device state of the Internet of Things device whose device state has changed to the cloud server through the user terminal.

[0099] In the smart home application scenario, it is assumed that each family has several air conditioners, multiple smart sockets, multiple smart switches, an ice washing machine and many other electrical appliances. At this time, the number of device states that each family needs to report is dozens or even hundreds. At this time, the home host can effectively reduce the order of magnitude of the reported device states, and effectively reduce the polling pressure and polling time of the cloud server by reporting the device states of the Internet of Things devices.
