The term "machine-readable medium" can include, without being limited to, wireless channels and various other media capable of storing, containing, and/or carrying instruction(s) and/or data.

With the rise of the internet of things (Internet of things, IOT), a large number of intelligent terminal devices are put into use. The Internet of things combines various Internet of things devices with the Internet to form a huge network, so that the interconnection and intercommunication of people, machines and objects at any time and any place are realized.

In particular, smart home appliances have been taken into thousands of households. For example, the functions of remote control, data reporting, device related data issuing and the like of the internet of things device can be conveniently realized through interaction among an Application (APP), an IOT cloud platform and the internet of things device.

Because of the limitation of hardware, the internet of things equipment often uses limited application protocols (Costrained Application Protocal, coAP)/message queue telemetry transport (Message Queuing Telemetry Transport, MQTT) and other internet of things protocols in the interaction process with the IOT cloud platform. And establishing a communication path with the IOT cloud platform through establishing a transmission control protocol (Transmission Control Protocol, TCP) long connection, ensuring the activity of the communication path through a timing heartbeat mechanism, and supporting the remote control capability of the IOT cloud platform and the Internet of things equipment.

It should be noted that, the internet of things device based on mobile cellular connection needs to maintain a connection with the server. But the internet of things equipment and the server remain connected to occupy the base station resources. Because of the limited resources of the base station and the regular base station, when the mobile internet of things equipment communicates with the server, the base station can allocate an internet protocol (Internet Protocol, IP) address to the internet of things equipment, if no data is transmitted for a certain time, the base station can cancel the allocation of the IP address to the internet of things equipment and release the resources to other demands, so that the internet of things equipment timing and the server are required to establish communication to keep a communication channel clear, and the timing is named as a heartbeat period. The short heartbeat period can ensure that the information of the service layer can be reached at any time, but the server is excessively loaded, and the power consumption is increased; if the heartbeat period is too long, connection failure between the Internet of things equipment and the server can be caused, and at the moment, the Internet of things equipment must initiate connection again to acquire IP address allocation from the base station, so that communication efficiency can be reduced, and too high power consumption of the server and the Internet of things equipment can be caused.

The heartbeat cycle can also be understood as that the internet of things device sends a data packet to the IOT cloud platform every other period of time, the IOT cloud platform is informed that the IOT cloud platform is still online, the IOT cloud platform and the internet of things device interact every other period of time to judge whether the link is effective or not, and some possibly necessary data are transmitted. It is often not guaranteed whether a TCP socket connection is continuously active after the connection is established, and applications on both sides will periodically send heartbeat packets to ensure that the connection is active. Because the data packets are transmitted according to a certain time interval and are similar to heartbeat, the data packets transmitted by the internet of things equipment are called heartbeat packets, and the time between transmitting the two heartbeat packets is called a heartbeat period. And judging whether the Internet of things equipment is in an offline state or not by periodically sending heartbeat packets between the Internet of things equipment and the IOT cloud platform.

However, when the internet of things device does not send the heartbeat packet to the IOT, the internet of things device cannot be described as being in an offline state, and the internet of things device also needs to have a timeout period, so that the accuracy of the online state of the internet of things device always has an error of 2% -3%.

In general, a timeout period refers to the time of three heart cycles. In other words, after the internet of things device fails to send the heartbeat packet, the internet of things device still continues to try to send the heartbeat packet for three times, so that the internet of things device also needs to wait for the time of three heartbeat cycles at the IOT cloud platform end, and if the time of the three heartbeat cycles is waited, the terminal device is finally judged to be in an offline state. Therefore, the accuracy of the online state of the terminal device always has an error.

The method for detecting the heartbeat of the internet of things device in the related art is specifically described below with reference to fig. 1.

Fig. 1 shows an interaction schematic diagram among an internet of things device, an IOT cloud platform and a terminal device in the related art. As shown in fig. 1, the internet of things device may send a heartbeat packet to the IOT cloud platform in a heartbeat period to indicate whether the IOT cloud platform is in an online state or not, and the IOT cloud platform may periodically receive the heartbeat packet sent by the internet of things device, determine whether the physical network device is in an offline state according to a heartbeat timeout time, and the IOT cloud platform may present the offline state of the internet of things device on an APP of a terminal device bound to the internet of things device, where a user may query the offline state of the internet of things device through the APP.

It should be noted that, the heartbeat signaling from the internet of things device to the IOT cloud platform is defined in the CoAP/MQTT protocol, and the internet of things device can keep alive at regular time according to the heartbeat period.

It should be further noted that, when the IOT cloud platform determines whether the internet of things device is in an online state, the existing heartbeat cycle generally obtains a suggested value from an operator, or performs an experiment on the basis, and then sets according to the experimental value. However, the rules of the base station in the cellular network may change with time, location, upgrade and transformation of the operator equipment, service evolution, and other factors affecting the heartbeat cycle. Therefore, under the existing heartbeat period, the IOT cloud platform needs to judge that the internet of things equipment is in an offline state based on the timeout period, and when the IOT cloud platform feeds back the internet of things equipment to the APP, a certain error exists in the offline state, and the user is finally caused to acquire the internet of things equipment from the APP in the offline state inaccurately.

In summary, the current IOT cloud platform determines the offline state of the terminal device based on the online timeout time of the internet of things device, when the internet of things device sends a heartbeat packet to the IOT cloud platform, and when the packet loss occurs, the IOT cloud platform can continue to wait for three heartbeat cycles and refresh the offline state of the internet of things device, which finally results in inaccurate accuracy of the online state of the current device. Therefore, a detection scheme capable of rapidly detecting whether the internet of things is online is needed.

In view of the above, the application provides a heartbeat detection method for an internet of things device, wherein when an internet of things platform does not receive heartbeat data sent by the internet of things device within a preset time length after receiving the heartbeat data for the last time, the method actively sends the heartbeat data to the internet of things device; and determining that the Internet of things equipment is in an online state or an offline state according to the heartbeat data sending result, wherein the Internet of things equipment is in the online state when the heartbeat data is sent successfully, and the Internet of things equipment is in the offline state when the second heartbeat data is sent successfully. In the method, when the Internet of things platform does not receive the heartbeat packet of the Internet of things device in the heartbeat period, the Internet of things platform starts an active detection mechanism to judge whether the Internet of things device is on line or not, and the Internet of things device can be judged to be in an off-line state after waiting for the timeout time.

Before introducing the heartbeat detection method of the internet of things equipment provided by the application, a system architecture and an application scene to which the method is applicable are described first. Fig. 2 shows a schematic diagram of an architecture of a heartbeat detection system of an internet of things device according to an embodiment of the present application.

As shown in fig. 2, the system comprises an internet of things platform, internet of things equipment and terminal equipment, wherein the internet of things platform comprises an equipment gateway, equipment shadow and heartbeat data big data.

The terminal device refers to a device in which a service application is installed, and may also be referred to as a device in which a client is installed. The user can access the Internet of things platform through a client installed on the terminal equipment or access the Internet of things platform through the service server, and the user can view the Internet of things equipment in communication connection with the Internet of things platform through the client, view service data reported by the Internet of things equipment, and can also issue control commands and the like to the Internet of things equipment through the client.

The terminal device according to the embodiment of the present application may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing device connected to a wireless modem. The wireless terminals may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), which may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access network. Such as Personal communication services (Personal Communication Service, PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal DIGITAL ASSISTANT, PDA) and the like. A wireless Terminal may also be referred to as a system, subscriber Unit (Subscriber Unit), subscriber Station (Subscriber Station), mobile Station (Mobile Station), remote Station (Remote Station), access Point (Access Point), remote Terminal (Remote Terminal), access Terminal (ACCESS TERMINAL), user Terminal (User Terminal), terminal Device, user Agent (User Agent), user Device (User Equipment), or User Equipment (User Equipment), and the application is not limited in particular.

The internet of things device refers to an access device with a sensor detection function or an intelligent function in the internet of things, such as a device supporting a temperature detection sensor or a household internet of things device (can be an intelligent home system formed by a plurality of devices), for example, a small intelligent switch, an intelligent ammeter, an intelligent water meter, an intelligent electric lamp, a large intelligent television, an intelligent water fountain, an intelligent air conditioner, an intelligent floor heating device, an intelligent projector, an intelligent washing machine or an intelligent electric cooker and the like used in the life of a user.

The internet of things platform is connected with the internet of things equipment, supports the internet of things equipment to report service data, provides the service data for users, or receives control commands issued by the users to the internet of things equipment. The internet of things platform is also in communication connection with a network application or a service application built in the terminal equipment. For example, in the smart home system scenario, if the device a in the smart home system wants to interact with the device B in the smart home system, the interaction needs to be implemented through the internet of things platform forwarding.

Optionally, as shown in fig. 2, in the heartbeat detection system of the internet of things provided by the present application, after the internet of things device and the internet of things platform are connected, the internet of things device may send relevant information to itself, for example: the method comprises the steps that equipment information of the Internet of things equipment, region information of the Internet of things equipment and network information of the Internet of things equipment are sent to an Internet of things platform, and then the Internet of things platform determines the heartbeat cycle of the Internet of things equipment and determines whether to start a heartbeat active detection mechanism according to at least one of the information.

The device gateway on the internet of things platform can receive the related information of the internet of things sent by the internet of things device, then analyze the related protocol and send the related protocol to the device shadow, and the device shadow can inquire the heartbeat period under the current scene and whether the internet of things platform starts a heartbeat active detection mechanism from the device heartbeat database.

Therefore, the system provided by the application can determine the heartbeat period of the Internet of things equipment and whether to start the heartbeat active detection mechanism and store the heartbeat period through the IOT according to the related information of the Internet of things equipment, and when the IOT does not receive the heartbeat packet of the terminal equipment in the heartbeat period, the IOT starts the active detection mechanism to judge whether the terminal equipment is on line or not, and the terminal equipment can be judged to be in an off-line state without waiting for the timeout time.

The heartbeat detection method of the Internet of things provided by the embodiment of the application is described in detail below with reference to the accompanying drawings.

Fig. 3 is a schematic flowchart illustrating a heartbeat detection method 300 of an internet of things device according to an embodiment of the present application from a device interaction perspective. As shown in fig. 3, the method 300 shown in fig. 3 may include steps S310 to S370. The various steps in method 300 are described in detail below in conjunction with FIG. 3.

It should be understood that, in the embodiment of the present application, the method 300 is described taking the internet of things platform, the internet of things device, and the terminal device as the execution bodies of the execution method 300 as an example. By way of example and not limitation, the execution subject of the execution method 300 may also be a chip applied in an internet of things platform, an internet of things device, and a terminal device.

S310, the first Internet of things device sends related information of the first Internet of things device to an Internet of things platform, wherein the related information comprises one or more of the following items: the method comprises the steps of equipment information of first Internet of things equipment, region information of the first Internet of things equipment or network information of the first Internet of things equipment.

It should be noted that the first internet of things device refers to any one of a plurality of internet of things devices communicatively connected to the internet of things platform.

Since the existing heartbeat cycle is generally obtained from an operator as a recommended value, or experiments are performed on the basis of the recommended value, and then the heartbeat cycle is set according to the experimental value. However, the base station rule in the cellular network may change the heartbeat period due to the influence of factors such as time, location, upgrading and reconstruction of operator equipment, service evolution and the like, so that the IOT cloud platform can only judge that the terminal equipment is in an offline state based on a timeout period under the existing heartbeat period, and finally, the accuracy of the online state of the terminal equipment is caused to have errors.

Therefore, in the embodiment of the application, the first internet of things device can acquire the target heartbeat cycle according to the related information of the first internet of things device, and based on the target heartbeat cycle and the heartbeat maintenance of the internet of things platform, the internet of things platform can rapidly determine the offline state of the first internet of things device based on the target heartbeat cycle.

For example, when the first internet of things device is a smart refrigerator, the heartbeat cycle of the batch of smart refrigerators of the model set by the factory is 30S, but when the batch of smart refrigerators use different scenes, the heartbeat cycle is not maintained at 30S. Suppose that at a certain place, the intelligent refrigerator has a heartbeat cycle of 40s due to the influence of the network environment. And when the internet of things platform does not receive the heartbeat data sent by the intelligent refrigerator when the period is 30s, the internet of things platform can actively send the heartbeat data to detect. However, in the current situation, the intelligent refrigerator is heartbeat data sent in a period of 40s, so that the judgment of the intelligent refrigerator in an off-line state is inaccurate.

Then, in order to obtain the target heartbeat cycle of the first physical network device, when the internet of things device is connected with the internet of things platform, relevant information of the first internet of things device can be sent to the internet of things platform, and the internet of things platform is utilized to determine the target heartbeat cycle.

The related information of the first internet of things device includes: device information of the first internet of things device, such as: the device information may include a device type, a charging type, etc., such as a charging type of a smart desk lamp, a smart refrigerator, or a smart jack, etc. Of course, the internet of things device may also be other devices with a sensor detection function or an access device with an intelligent function, for example, a charging type of an intelligent sound, etc., which is not limited by the embodiment of the present application. The charging type may be plug-in or lithium battery-mounted.

The region information of the first internet of things device is: the geographic location of use of the internet of things device, for example, a specific city, a specific street in the city, or a specific cell in the street, etc. The embodiment of the application does not limit the range of the regional information of the physical network equipment.

The network information of the first internet of things device refers to: the information of the operator to which the internet of things device is connected, for example, a mobile network, a corporate network, a telecommunication network, or the like, or the network information may be information of other operators than the three major operators.

The first internet of things device can send the related information of the at least one internet of things device to the internet of things platform, and the target heartbeat cycle acquired by the internet of things platform is utilized.

S320, the Internet of things platform determines a target heartbeat cycle of the first Internet of things device based on the related information of the first Internet of things device.

In the implementation of the application, after the internet of things platform acquires the related information of the first internet of things device, the target heartbeat cycle of the current internet of things device is determined by utilizing the related information of the first internet of things device.

When the internet of things platform obtains the target heartbeat period of the current internet of things device, the time for the first internet of things device to send the heartbeat data can be determined based on the target heartbeat period. When the first Internet of things equipment loses the packet, the Internet of things platform can rapidly and accurately determine whether the first Internet of things equipment is in an on-line state or an off-line state.

In some embodiments, the internet of things platform may search for a target heartbeat period in the device heartbeat database based on the related information of the first internet of things device, and return the target heartbeat period to the first internet of things device side.

It should be noted that, the device heartbeat database has a mass data management capability, and the device heartbeat database includes a target heartbeat detection period under the condition that device information of the internet of things device is different, under the condition that region information of the internet of things device is different, or under the condition that network information of the internet of things device is different.

For example: the device heartbeat database comprises: the target heartbeat period is 10s when the equipment information of the physical network equipment is an intelligent desk lamp with plug-in type; or the target heartbeat period is 15s when the network information of the intelligent desk lamp is a telecommunication network; or the region information of the intelligent desk lamp is 20s of the target heartbeat period when Nanjing.

Also for example: the device heartbeat database comprises: when the equipment information of the physical network equipment is an intelligent desk lamp with plug-in type, the network connected with the Internet of things equipment is a telecommunication network, and the region where the Internet of things equipment is located is western security, the heartbeat cycle of the Internet of things equipment is 1min.

The device heartbeat database may further include: when the equipment information of the physical network equipment is lithium battery type intelligent desk lamp, the network connected with the Internet of things equipment is a mobile network, and the region where the Internet of things equipment is located is Nanjing, the heartbeat cycle of the Internet of things equipment is 2min.

Then, after the internet of things platform obtains the related information of the internet of things device, the related information is compared in the device heartbeat database, so that the target heartbeat period is found out.

For example, when the related information of the first internet of things device acquired by the internet of things platform is the second condition, the target heartbeat period of the internet of things device is 2min.

It will be appreciated that the target heart cycle is the result of a search in the current device heart database, and that since the results in the heart database are dynamically changing, the target heart cycle is also dynamically changing, in other words, the results of the target heart cycle are different when searched at different times.

It may be seen that, in the above example, the device heartbeat database may determine the target heartbeat period of the first internet of things device based on the device information of the first internet of things device, or the region information where the first internet of things device is located, or the network information of the first internet of things device. The target heartbeat period can also be determined based on the device information of the first internet of things device, the region information of the first internet of things device and the network information of the first internet of things device. However, the target heartbeat period determined by the single factor may not be accurate enough compared with the target heartbeat period determined by the plurality of factors, which ultimately results in determining that the first internet of things device is in an online state or an offline state.

In one possible implementation manner, the device gateway on the internet of things platform may accept information about the internet of things device sent by the first internet of things device, and illustratively, the information about the first internet of things device may be sent by a CoAP protocol. And then the device gateway receives the CoAP protocol and analyzes the CoAP protocol, so that the related information of the first internet of things is obtained, and the related information of the first internet of things can be sent through other protocols.

After the device gateway obtains the related information of the first internet of things device, the device shadow can be called, and then the device shadow inquires a target heartbeat period in the current scene from the device heartbeat database.

S330, the Internet of things platform sends a target heartbeat cycle to the first Internet of things device.

S340, the first Internet of things device sends first heartbeat data to the Internet of things platform according to the target heartbeat cycle.

In the embodiment of the application, after the internet of things platform determines the target heartbeat cycle based on the related information of the first internet of things device, the internet of things device also needs to return the target heartbeat cycle to the first internet of things device, so that the first internet of things device can send heartbeat data based on the target heartbeat cycle.

And after the first Internet of things equipment receives the target heartbeat period sent by the Internet of things platform, sending first heartbeat data to the physical network platform according to the target heartbeat period.

S350, when the Internet of things platform does not receive the first heartbeat data in the target heartbeat period, sending second heartbeat data to the first Internet of things device.

It should be understood that, under normal circumstances, the first internet of things device may keep the TCP link active according to the first heartbeat data sent by the internet of things platform at the timing of the target heartbeat period, and then the internet of things platform may receive the first heartbeat data in the target heartbeat period.

However, when the heartbeat data in the target period do not arrive at the internet of things platform on time due to the abnormality in the data link, the internet of things platform does not receive the heartbeat data in the target heartbeat period, and the internet of things platform can actively send second heartbeat data to the first internet of things device, and the validity of connection is detected, so that the first internet of things device is judged to be in an offline state.

Optionally, as a possible implementation manner, before the internet of things platform sends the second heartbeat data to the first internet of things device, the internet of things platform may determine, based on the related information of the first internet of things device, whether the first internet of things device starts the heartbeat active detection mechanism, and under the condition that the first internet of things device starts the heartbeat active detection mechanism, send the second heartbeat data to the first internet of things device again.

Specifically, after the first internet of things device sends the relevant information of the first internet of things device to the internet of things platform, the internet of things platform searches for whether the internet of things device starts a heartbeat active detection mechanism in different scenes in the device heartbeat database based on the relevant information of the first internet of things device.

It should be understood that the device heartbeat database has a mass data management capability, and includes, in addition to a target heartbeat detection period when the device information of the internet of things device is different, when the region information of the internet of things device is different, or when the network information of the internet of things device is different, whether the internet of things device starts a heartbeat active detection mechanism in different scenes. When the internet of things platform determines whether to start the heartbeat detection mechanism based on the related information of the internet of things equipment, the internet of things platform can store whether to start the heartbeat detection mechanism, and when the internet of things platform does not receive the first heartbeat data sent by the internet of things equipment in the target heartbeat period, whether to start the heartbeat active detection mechanism is determined, and under the condition that the heartbeat active detection mechanism is started, the second heartbeat data is sent to the first internet of things equipment, the validity of connection is detected, and therefore the first internet of things equipment is judged to be in an offline state.

For example: the device heartbeat database comprises: when the equipment information of the physical network equipment is an intelligent desk lamp with plug-in type, the network connected with the Internet of things equipment is a telecommunication network, and the region where the Internet of things equipment is located is western security, the heartbeat cycle of the Internet of things equipment is 1min, and an active heartbeat detection mechanism needs to be started.

It should be noted that, the internet of things platform may determine whether the first internet of things device is in a weak network based on the related information of the first internet of things device, and when the first internet of things device is in the weak network, the possibility of packet loss of the device is indicated to be greater, so that a heartbeat active detection mechanism needs to be started. When the first internet of things device is in the strong network, the device may not start the heartbeat active detection mechanism because the device is less likely to lose packets when in the strong network. Therefore, even when the internet of things platform does not receive the first heartbeat data sent by the first internet of things device in the target heartbeat period, the internet of things platform does not need to send the second heartbeat data, because the internet of things platform determines that the device has less possibility of packet loss based on the related information of the first internet of things device, the connection can be automatically restored after a period of time.

S360, judging whether the first Internet of things equipment is in an online state or an offline state according to the second heartbeat data sending result.

It is understood that when the internet of things platform sends the second heartbeat data to the first internet of things device, the first internet of things device is indicated to keep on line, and when the internet of things platform fails to send the second heartbeat data to the first internet of things device, the first internet of things device is indicated to be off line.

It should be noted that, when a plurality of internet of things devices are connected on the internet of things platform and the plurality of internet of things devices all need to start the active heartbeat detection mechanism, the internet of things platform can select the internet of things device which needs to send heartbeat data in the current state in an algorithm mode, so that resource consumption is reduced.

In one possible implementation manner, when heartbeat data sent by the first internet of things Device to the internet of things platform is lost due to a network between the first internet of things Device and the physical network platform, the Device gateway micro-service on the internet of things platform acquires the last heartbeat time of the first internet of things Device and a Device identifier (Device ID) of the internet of things Device and reports the last heartbeat time to the Device shadow micro-service on the internet of things platform. It should be understood that the Device ID is an identifier given by the internet of things platform to each internet of things Device connected to the internet of things platform.

Further, the Device shadow micro-service queries a connection image of the internet of things Device in a Device heartbeat database according to the Device ID of the first internet of things Device, if the last heartbeat time is longer than the heartbeat timeout time, queries whether the internet of things Device starts a heartbeat active detection mechanism, and if the first internet of things Device starts the heartbeat active detection mechanism, the Device gateway micro-service actively initiates a heartbeat detection signaling of connection effectiveness to the internet of things Device.

When the heartbeat data transmission of the equipment gateway micro-service to the first Internet of things equipment is successful, the first Internet of things equipment is indicated to keep on line, and when the heartbeat data transmission of the equipment gateway micro-service to the first Internet of things equipment is failed, the first Internet of things equipment is indicated to be offline.

And finally, the device gateway micro service updates the offline state of the Internet of things device to the device shadow micro service according to the active detection result, if the Internet of things device is disconnected, the connection resource is released, and if the Internet of things device is online, the connection resource is maintained.

S370, the Internet of things platform updates the first Internet of things device to the terminal device in an offline state.

And finally, the real state of the Internet of things equipment is displayed to an application program of the terminal equipment held by the user by the Internet of things platform, and the user can conveniently and rapidly know the offline state of the Internet of things equipment through the application program on the terminal equipment.

Specifically, when the internet of things platform judges that the internet of things device is online, the online state of the internet of things device is updated to the terminal device. When the Internet of things platform judges that the Internet of things equipment is offline, the offline state of the Internet of things equipment is updated to the terminal equipment, so that a user can conveniently know the offline state of the Internet of things equipment.

According to the method for detecting the heartbeat of the Internet of things, which is provided by the application, the platform of the Internet of things can be based on the related information of the equipment of the Internet of things, and the related information comprises one or more of the following items: the method comprises the steps of determining a target heartbeat period of terminal equipment and whether an active detection mechanism is started and stored according to the type of the Internet of things equipment, region information of the Internet of things equipment or network information of the Internet of things equipment, and judging whether the Internet of things equipment is on line or not by the active detection mechanism when the Internet of things platform does not receive the heartbeat data of the terminal equipment in the target heartbeat period, and judging that the Internet of things equipment is off-line without waiting for timeout time, so that the detection rate of the Internet of things equipment in the off-line state is improved.

It should be noted that, in the method 300, when the first internet of things device does not receive the first heartbeat data in the target heartbeat period, the internet of things platform sends the second heartbeat data to the first internet of things device, and of course, the internet of things platform may also send the second heartbeat data to the first internet of things device when the first heartbeat data sent by the first internet of things device is not received in a preset time length after the last heartbeat data is received; that is, the preset time length may be the target heartbeat period or other time lengths, for example, a factory heartbeat period of the first internet of things device. The embodiment of the present application is not limited in this regard.

The heartbeat detection method of the internet of things device is illustrated by taking a terminal device as a smart phone, a first internet of things device as an intelligent socket (model: a Bo-Union intelligent socket mini-HL) and an internet of things platform as an IOT cloud platform as examples in combination with fig. 4 and 5. Fig. 4 is a schematic flow chart of another example of a heartbeat detection method 400 of an internet of things device according to an embodiment of the present application, and fig. 5 is a schematic interface diagram of another example of heartbeat detection of an internet of things device.

As shown in fig. 4, the method 400 includes S410-S491:

A user may add an internet of things device through the smart APP, for example, by SoftAP to find a smart socket.

The Soft wireless Access Point (AP) is a technology for realizing the AP function on a smart phone by using special software through a wireless network card, and can replace the AP in a wireless network so as to reduce the cost of wireless networking.

After the APP searches the smart jack, the name and the password of the current WiFi service set identifier (SERVICE SET IDENTIFIER, SSID) are transmitted to the smart jack through the network, so that the network of the smart phone and the smart jack is synchronized.

Step S410 may refer to the interface shown in (a) of fig. 5-the interface shown in (d) of fig. 5, as shown in (a) of fig. 5, after the smart phone receives the click operation of the user, the smart phone opens the smart life APP, the user clicks the add device component on the smart life APP interface, in response to the click operation of the add device by the user, the smart phone interface switches to the interface shown in (b) of fig. 5, as shown in (b) of fig. 5, and reminds "please ensure that the internet of things device is connected to a power supply and is located near the mobile phone" on the display interface, when the internet of things device near the smart life APP scans, the internet of things device can be found based on the wireless network, and also the internet of things device can be found by manually adding or code sweeping adding.

After the APP searches the intelligent socket of the network to be distributed, the intelligent mobile phone interface is switched to the interface of the diagram (c) in fig. 5, and as shown in the diagram (c) in fig. 5, the intelligent socket icon and the intelligent socket name are the Bolian intelligent socket mini-HL are displayed on the interface, and a user can click an adding component on the interface to connect. When the APP is connected to the smart jack of the network to be configured, the network needs to be connected to the smart jack, the smart phone interface is switched to the interface of the (d) diagram in fig. 5, and as shown in the (d) diagram in fig. 5, options such as network setting, network selection, and password are displayed on the interface, and the user can click on the selected network to transmit the current service set identifier SSID name and password of the WiFi to the smart jack through the network.

S420, the intelligent socket reports relevant information of the intelligent socket to a device gateway, wherein the relevant information comprises one or more of the following: the device information of the intelligent socket, the region information of the intelligent socket and the network information of the intelligent socket.

When the intelligent socket networking is successful, related information of the intelligent socket is firstly required to be reported to a device gateway on the IOT cloud platform.

The related information includes one or more of the following: the device information of the intelligent socket, the region information of the intelligent socket and the network information of the intelligent socket. Illustratively, the relevant information of the smart socket in step S420 may be device information of the smart socket and network information of the smart socket.

Step S420 may refer to the interface shown in (e) diagram in fig. 5-the interface shown in (g) diagram in fig. 5, as shown in (e) diagram in fig. 5, the smart socket successfully checks the current network information, and as shown in (f) diagram in fig. 5, the smart socket checks the current device information, and reports the device information and the network information to the device gateway micro-service on the IOT cloud platform through the CoAP protocol, and maintains a long connection with the IOT cloud platform through the device gateway micro-service. As shown in the (g) diagram of fig. 5, the smart jack can be seen on the smart phone interface in an on-line state and can be timed and counted down by the APP.

It should be understood that in the example of fig. 5, the internet of things device connected to the smart phone through the smart life APP is a smart desk lamp, and of course, other internet of things devices may be bound in the smart life APP. For example: as shown in fig. 5 (g), a mosquito killer or a fish lamp, etc.

And S430, the device gateway reports the relevant information of the intelligent socket to the device shadow.

And the device gateway micro-service on the IOT cloud platform analyzes the CoAP protocol, analyzes the device information and the network information of the intelligent socket, and invokes the device shadow micro-service.

S440, the device shadow calls a device heartbeat database to inquire a target heartbeat period of the intelligent socket and whether an active detection mechanism is started.

The device shadow micro-service queries a target heartbeat period suitable for the intelligent socket in the current scene in a device heartbeat database and whether to start a heartbeat active detection mechanism.

It should be understood that, in the current scenario, the device information of the smart jack and the network information of the smart jack may be specifically referred to the description in step S320, and will not be described herein.

S450, the device shadow sends the inquired target heartbeat cycle of the intelligent socket to the device gateway or not when the active detection mechanism is started.

S460, the device gateway sends the target heartbeat cycle to the intelligent socket.

And returning the inquired target heartbeat cycle to the Internet of things equipment, keeping long connection between the intelligent socket and the Internet of things platform, and keeping message communication with the equipment gateway according to the heartbeat cycle returned by the Internet of things platform. And displaying the inquired heartbeat period and whether to start an active detection mechanism on the intelligent life APP for the user to inquire.

And S470, the intelligent socket sends the first heartbeat data to the equipment gateway based on the target heartbeat cycle.

And S480, when the equipment gateway does not receive the heartbeat data packet in the target heartbeat period, the equipment gateway inquires the last time of sending the heartbeat packet by the intelligent socket.

And S490, if the heartbeat is overtime, the device shadow inquires whether to start a heartbeat initiative detection mechanism in a device heartbeat database.

And S491, when the intelligent socket starts the heartbeat active detection mechanism, the equipment gateway actively transmits second heartbeat data to the intelligent socket, when the second heartbeat data packet is successfully transmitted, the intelligent socket is in an on-line state, and when the second heartbeat data packet is not successfully transmitted, the intelligent socket is in an off-line state.

The user can check whether the intelligent platform side is started or not and how much the device heartbeat cycle is through the APP. As shown in the (h) diagram in fig. 5, after a user clicks the intelligent platform side active detection component on the APP, the interface shown in the (h) diagram in fig. 5 is switched to the interface shown in the (i) diagram in fig. 5, and the active detection mechanism of the internet of things equipment side and the heartbeat cycle of the intelligent socket are displayed on the interface shown in the (i) diagram in fig. 5 for 50s.

Fig. 6 shows an interface schematic diagram of an intelligent socket on an APP in an offline state, when an heartbeat data packet sent by the intelligent socket to the IOT cloud platform is overtime, the IOT cloud platform actively sends the heartbeat data packet to the intelligent socket to actively detect the intelligent socket in the offline state, when the heartbeat data packet sent by the IOT cloud platform fails, the intelligent socket is indicated to be in the offline state, as shown in the (a) diagram in fig. 6, a switch icon of the intelligent socket indicated by a dotted line is not turned on, when the heartbeat data packet sent by the IOT cloud platform succeeds, the intelligent socket is indicated to be in the online state, as shown in the (b) diagram in fig. 6, the switch icon of the intelligent socket indicated by the dotted line is turned on, and a user can quickly acquire the intelligent socket in the offline state on the APP.

In summary, fig. 4 to fig. 6 specifically describe that after the intelligent socket reports relevant information of the intelligent socket to the IOT cloud platform, the IOT cloud platform determines, based on the relevant information of the intelligent socket, a target heartbeat period of the intelligent socket in a current scenario and whether to start a heartbeat active detection mechanism, and sends the target heartbeat period to the intelligent socket, the intelligent socket keeps heartbeat connection with the IOT cloud platform based on the target heartbeat period, when the IOT cloud platform does not receive first heartbeat data sent by the intelligent socket in the target heartbeat period, and the IOT cloud platform detects that the intelligent socket needs to start the heartbeat active detection mechanism, the IOT cloud platform actively sends second heartbeat data to the intelligent socket, when the second heartbeat data is sent successfully, the IOT cloud platform indicates that the intelligent socket is in an online state, and when the second heartbeat data is sent failed, the IOT cloud platform indicates that the intelligent socket is in an offline state. According to the method, the IOT cloud platform actively transmits the heartbeat data after not receiving the heartbeat data, so that the offline state of the intelligent socket can be rapidly acquired, the offline state of the intelligent socket is judged without waiting for the timeout time (3 heartbeat cycles), and the accuracy of judging the offline state of the intelligent socket is improved.

In the method for detecting the heartbeat of the equipment of the Internet of things, the equipment heartbeat database can be updated, for example, according to the equipment information of the Internet of things which is automatically set by a user, the equipment information of the Internet of things in the equipment heartbeat database is updated in real time.

Specifically, the user can autonomously set the heartbeat cycle of the internet of things device on the terminal device and whether to start the heartbeat active detection mechanism, and the internet of things platform sends a request to the internet of things device according to the heartbeat cycle of the internet of things device set in the terminal device and whether to start the heartbeat active mechanism, wherein the request is used for requesting related information of the internet of things device, and the related information comprises one or more of the following items: the method comprises the steps that equipment information of the Internet of things equipment, region information where the Internet of things equipment is located and network information of the Internet of things equipment, the Internet of things equipment sends relevant information of the Internet of things equipment to an Internet of things platform based on a request of the Internet of things platform, and then the Internet of things platform updates the portrait of the Internet of things equipment in the Internet of things platform based on the relevant information of the Internet of things equipment, a heartbeat period of the Internet of things equipment and whether a heartbeat active detection mechanism is started or not.

The method for updating the heartbeat database of the equipment provided by the embodiment of the application is described in detail below with reference to the accompanying drawings.

It will be appreciated that updating the device heartbeat database includes two meanings: the first method refers to that related information of a certain internet of things device does not exist in the device heartbeat database, and then the types of the internet of things device in the device heartbeat database can be expanded based on the following method. The second means that the related information of a certain internet of things device originally exists in the heartbeat database is set, and then the related information of the internet of things device can be updated based on the following method.

Fig. 7 is a schematic flow chart diagram illustrating a method 700 of updating a device heartbeat database provided by an embodiment of the present application from a device interaction perspective. As shown in fig. 7, the method 700 shown in fig. 7 may include steps S710 to S750. The various steps in method 700 are described in detail below in conjunction with fig. 7.

It should be understood that, in the embodiment of the present application, the method 700 is described by taking the internet of things platform, the internet of things device, and the terminal device as the execution bodies of the execution method 700. By way of example, but not limitation, the execution subject of the execution method 700 may also be a chip applied in an internet of things platform, an internet of things device, and a terminal device.

S710, the terminal equipment acquires a heartbeat period of the second internet equipment set by the user and whether an active detection mechanism is started.

It should be noted that the second internet of things device is any one of a plurality of internet of things devices communicatively connected to the internet of things platform. The second internet of things device may be the same device as the first internet of things device, or may be a different device from the first internet of things device.

In the embodiment of the application, the user can set the heartbeat cycle of the Internet of things device on the terminal device according to the self requirement or the environment where the second Internet of things device is located, and whether to start the active detection mechanism.

For example, when the second internet device is an intelligent sweeping robot, the user wants to ensure whether the intelligent sweeping robot is always in a sweeping state, for a shorter heartbeat period can be set, and an active detection mechanism is started, so that the user can be basically guaranteed to know that the intelligent sweeping robot is in an offline state at the first time.

For example, when the second internet device is an intelligent desk lamp with a lithium battery, and the area where the intelligent desk lamp is located and the connected network state are good, the user can properly set a longer heartbeat cycle and does not need to start the heartbeat active detection mechanism in order to reduce the power consumption of the intelligent desk lamp.

In some embodiments, the terminal device may select an internet of things device to be set, and the terminal device may further obtain state data of the internet of things device stored on the internet of things platform. And then, the terminal equipment stores the heartbeat cycle and the active detection mechanism of the Internet of things equipment set by the user in the current state data in a personalized way.

Optionally, an application program installed on the terminal device may select an internet of things device to be set, and obtain, through the application program on the terminal device, state data of the internet of things device stored in a device shadow on the internet of things platform. Then, the application program on the terminal equipment sets the heartbeat cycle and the active detection mechanism of the Internet of things equipment according to the individuation in the current state data.

S720, the internet of things platform sends a request message to the second internet of things device based on information set by a user on the terminal device, wherein the request message is used for requesting related information of the second internet of things device, and the related information comprises one or more of the following: device information of the second internet-of-things device, region information in which the second internet-of-things device is located, or network information of the second internet-of-things device.

In one possible implementation manner, the terminal device may upload the heartbeat cycle of the internet of things set by the user and whether to start the heartbeat active detection mechanism to the device shadow micro-service on the platform of the internet of things.

Furthermore, the device shadow micro-service can synchronously update the heartbeat period of the second internet-connected device and whether to start the heartbeat initiative detection mechanism into the device heartbeat database.

After the internet of things platform obtains the heartbeat cycle of the internet of things device set on the terminal device and whether to start the active detection mechanism, the internet of things platform needs to obtain the type information of the second internet of things device, the region information where the second internet of things device is located or the network information of the second internet of things device, so that the information of the second internet of things device in the device heartbeat database is perfected, and therefore the internet of things platform can send a request message to the second internet of things device, and the message is used for requesting the second internet of things device to report the related information of the internet of things.

S730, the second internet of things device sends relevant information of the second internet of things device to the internet of things platform based on the request message of the internet of things platform.

And after the second internet of things device receives the request message sent by the internet of things platform, the second internet of things device sends the related information of the second internet of things device to the internet of things platform.

The related information includes one or more of the following: device information of the second internet-of-things device, region information in which the second internet-of-things device is located, or network information of the second internet-of-things device.
