Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
A method for transmitting and receiving data in an internet of things system is provided in the related art, and as shown in fig. 1, an implementation diagram of a data transmitting and receiving process in the internet of things system in the related art is shown. The internet of things system comprises an internet of things platform 101, a plurality of gateway devices and a plurality of internet of things devices.
In the internet of things system, the internet of things equipment communicates with the internet of things platform through the gateway equipment, in the related technology, a user manually configures the topological relation between the internet of things equipment and the gateway equipment, namely the internet of things equipment and the specified gateway equipment are statically bound, the internet of things equipment can only send data and receive instructions to the internet of things platform through the specified gateway equipment, for example, both the internet of things equipment 2 and the internet of things equipment 4 can only carry out data transmission with the internet of things platform 101 through the gateway equipment 1; both the internet of things device 1 and the internet of things device 3 can only perform data transmission with the internet of things platform 101 through the gateway device 2. When the gateway device 1 fails, the internet of things device 1 and the internet of things device 4 cannot communicate with the internet of things platform 101, and the topological relation between the internet of things device and the gateway device needs to be reconfigured manually, for example, the internet of things device 1 and the internet of things device 4 are manually bound with the gateway device 2 again, and after the internet of things device 1 and the physical network device 4 are restarted, the internet of things device 1 and the physical network device 4 can continue to communicate with the internet of things platform 101 through the gateway device 2.
By adopting the method in the technology, because the relationship between the internet of things equipment and the designated gateway equipment is statically bound, namely the internet of things equipment can only communicate with the internet of things platform through the designated gateway equipment, when the designated gateway equipment fails, the internet of things equipment needs to be manually bound with new gateway equipment, and after the internet of things equipment is restarted, the communication between the internet of things equipment and the internet of things platform can be recovered.
In order to solve the above problem, an embodiment of the present application provides a method for transmitting and receiving data in an internet of things system. Referring to fig. 2, a schematic diagram of an implementation environment provided by an exemplary embodiment of the application is shown. The implementation environment comprises an internet of things device 201, a gateway group 202 and an internet of things platform 203.
The internet of things 201 is an information acquisition device in an internet of things system, is mainly responsible for acquiring data, is generally provided with a sensor (such as a photovoltaic sensor, a speed sensor, a pressure sensor and the like), can convert information acquired by the device into an electric signal or output information in other required forms according to a certain rule, and besides acquiring and transmitting data, the internet of things device also needs to have data processing and storing functions and is generally applied to the fields of industry, power grids, smart homes, intelligent transportation and the like. In this embodiment, the internet of things device 201 may send the acquired device data to the internet of things platform 203 through the gateway device.
The internet of things device 201 and any gateway device included in the gateway group 202 are connected through a wired or wireless network.
The gateway group 102 is a set of at least two gateway devices, each gateway device is a computer system or a device providing data conversion service among multiple networks, and in the internet of things system, the gateway device is configured to receive device data uploaded by multiple internet of things devices, convert the device data into a predetermined format, and upload the device data to the internet of things platform 203. In this embodiment of the application, the gateway group 202 includes a gateway device 204 and a gateway device 205, and the gateway group 202 is associated with the internet of things device 201, that is, the internet of things device 201 may communicate with the internet of things platform 203 through any gateway device included in the gateway group 202, schematically, the internet of things device 201 may send device data to the internet of things platform 203 through the gateway device 204, and may also receive an instruction sent by the internet of things platform 203 through the gateway device 204.
The gateway device 204 or the gateway device 205 is connected with the internet of things platform 203 through a wired or wireless network.
The internet of things platform 203 is a cloud device in the internet of things system, and is configured to receive device data from the gateway device 104 or the gateway device 205, and store, process, and analyze the device data, so as to perform service discovery, provide a service query function, and implement an internet of things application service logic, and may be a server, a server cluster formed by a plurality of servers, or a cloud computing center. Optionally, the internet of things platform 203 includes a configuration center, where a corresponding relationship between the internet of things device and the gateway group, a corresponding relationship between the gateway group and the gateway device, and the like are stored in the configuration center, and optionally, the internet of things platform 203 may further include an access center, where the access center is configured to verify a device access request of the internet of things device 201 uploaded by the gateway device, and issue a request passing instruction after the verification passes.
In a possible implementation manner, when the internet of things device 201 comes online, an information acquisition request may be sent to a configuration center in the internet of things platform to acquire information of a gateway group 202 related to the internet of things device 201, where the gateway group 202 includes at least two candidate gateway devices, that is, a gateway device 204 and a gateway device 205, the internet of things device 201 may send device data to the internet of things platform 203 through the gateway device 204, and when the device data is failed to be sent, that is, when the gateway device 204 fails, the internet of things device 201 may further continue to send the device data to the internet of things platform 203 through the gateway device 205. By associating the Internet of things equipment with the at least two candidate gateway equipment, the Internet of things equipment can automatically select other candidate gateway equipment when the first gateway equipment breaks down, and can continuously communicate with the Internet of things platform through the other candidate gateway equipment, so that the relationship between the Internet of things equipment and the gateway equipment is prevented from being manually reconfigured, and the operation steps of recovering data transmission are simplified.
Referring to fig. 3, a flowchart of a data transmitting and receiving method in an internet of things system according to an exemplary embodiment of the present application is shown. This embodiment is described by taking the method as an example for use in the implementation environment shown in fig. 2, and the method includes the following steps.
Step 301, the internet of things platform sends gateway group information to the target internet of things device, wherein the gateway group information includes gateway information of at least two candidate gateway devices.
The gateway group information comprises gateway information of at least two candidate gateway devices, namely, the target internet of things device is associated with a plurality of candidate gateway devices.
In a possible implementation manner, when a target internet of things device is online, a configuration center in an internet of things platform is used to obtain gateway group information associated with the target internet of things device, when the internet of things platform receives a request for obtaining the gateway group information from the target internet of things device and the request for obtaining the gateway group information is verified, the gateway group information (gateway information of at least two candidate gateway devices) is searched in the configuration center, and the searched gateway group information is sent to the target internet of things device.
Optionally, the gateway information may include a unique Identifier (ID) of the gateway device, an address of the gateway device, or the like, or gateway information of the gateway device that is needed when the other target internet of things device sends the device data, and the content included in the gateway group information is not limited in this embodiment.
Optionally, the domain name of the configuration center is known, and the internet of things device may access the configuration center through the domain name.
Step 302, the target internet of things device acquires gateway group information.
In a possible implementation manner, when the target internet of things device is online, gateway group information associated with the target internet of things device is acquired through a configuration center in the internet of things platform, and the gateway group information is stored in a corresponding position.
Optionally, the gateway group information related to the target internet of things device may also be directly stored in the target internet of things device, that is, when the internet of things device is on line, the gateway group information does not need to be acquired in the internet of things platform.
Step 303, the target internet of things device sends device data to the internet of things platform through a first gateway device of the at least two candidate gateway devices.
In a possible implementation manner, after the target internet of things device acquires the gateway group information, the number of the candidate gateway devices is determined, the number of the candidate gateways is subjected to modulo operation through the generated random number, the first gateway device is determined, and communication is performed with the internet of things platform through the first gateway device. The random number can be generated according to a device event of the target internet of things device, for example, the online time of the target internet of things device.
Illustratively, if the reference numbers of the candidate gateway devices are respectively gateway device 0, gateway device 1, gateway device 2, gateway device 3, and gateway device 4, that is, the number of the candidate gateway devices associated with the target internet of things device is 5, and if the random number generated according to the online time of the target internet of things device is 1, performing modulo operation to obtain a number 1, determining the gateway device 1 as the first gateway device.
Optionally, a number of candidate internet of things devices may also be modulo by using the pseudo random number to determine the first gateway device. The present embodiment does not limit the method for determining the first gateway device.
Illustratively, before the target internet of things device sends the device data through the first gateway device, the device access request needs to be sent through the first gateway device first, and only after the device access request is verified to be passed, the target internet of things device can send the device data to the internet of things platform through the first gateway device.
Step 304, the internet of things platform receives the device data sent by the target internet of things device through the first gateway device.
In a possible implementation manner, when the internet of things platform receives a device access request of a target internet of things device sent by a first gateway device, the device access request is firstly verified, and if the verification is passed, the target internet of things device is allowed to continue sending device data through the first gateway device.
When the device access request is verified, the device information of the target internet of things device is verified firstly, if the verification is passed, whether the target internet of things device is associated with the first gateway device or not is verified continuously, if the target internet of things device is associated with the first gateway device, the device access request is verified to be passed, and the target internet of things device is allowed to send device data through the first gateway.
Step 305, when the device data transmission fails, the target internet of things device determines a second gateway device from the at least two candidate gateway devices, wherein the second gateway device is different from the first gateway device.
In a possible implementation manner, when the sending of the device data by the internet of things device is not successful for N consecutive times, the first gateway device may malfunction, and at this time, the target internet of things device may determine a second gateway device from the candidate gateway devices, where the second gateway device is different from the first gateway device. Wherein N is a positive integer and is greater than or equal to 2.
Optionally, when the target internet of things device determines that the first gateway device fails, the first gateway device may be added to a blacklist, so that the first gateway device is skipped when the second gateway device is selected.
Optionally, the method for determining the second gateway device may refer to the method for determining the first gateway device, which is not described herein again.
And step 306, the target internet of things device sends device data to the internet of things platform through the second gateway device.
In a possible implementation manner, after the target internet of things device determines the second gateway device, the device data may continue to be sent to the internet of things platform through the second gateway device.
Optionally, before the device data is sent to the internet of things platform through the second gateway device, the device access request still needs to be verified, and after the device access request passes verification, the target internet of things device may continue to send the device data to the internet of things platform through the second gateway device.
Step 307, when the device data transmission fails, the internet of things platform receives the device data transmitted by the target internet of things device through the second gateway device.
In a possible implementation manner, the internet of things platform can monitor whether the gateway device fails, and when the internet of things platform monitors that the first gateway device fails, that is, the device data transmission fails, the target internet of things device is allowed to transmit the device data through the second gateway device.
Illustratively, when the internet of things platform receives device data sent by the target internet of things device through the second gateway device, the device information of the target internet of things device and the relationship between the target internet of things device and the second gateway device also need to be verified, and only after the verification is passed, the device data sent by the target internet of things device through the second gateway device is allowed to be received.
To sum up, in the embodiment of the present application, when the internet of things device acquires gateway group information, and the gateway group information includes gateway information of at least two candidate gateway devices, the device data is sent to the internet of things platform through a first gateway device of the at least two candidate gateway devices; when the equipment data transmission fails, the Internet of things equipment determines second gateway equipment different from the first gateway equipment from the at least two candidate gateway equipment, and equipment data is continuously transmitted to the Internet of things platform through the second gateway equipment.
Referring to fig. 4, a flowchart of a data transmitting and receiving method in an internet of things system according to another exemplary embodiment of the present application is shown. The embodiment is described by taking the method as an example for being used in the implementation environment shown in fig. 2, and the method includes the following steps.
Step 401, when the target internet of things device is on line, sending an information acquisition request to the internet of things platform, wherein the information acquisition request includes device information of the target internet of things device.
The device information refers to a device ID and device digest information of the target internet of things device, and the device digest information is generated by encrypting a device key of the target internet of things device.
In a possible implementation manner, when a target internet of things device is online, the device key is encrypted according to an encryption algorithm to generate device digest information, and the device ID of the target internet of things device, the device digest information, the encryption algorithm used for generating the device digest information, and the like are sent to a configuration center in an internet of things platform.
Optionally, the encryption algorithm may be a hash algorithm, or may be another encryption algorithm, and the type of the encryption algorithm used in the embodiment of the present application is not limited.
Optionally, the device ID of the target internet of things device is pre-stored in the target internet of things device with the device key.
Step 402, the internet of things platform receives an information acquisition request sent by a target internet of things device.
In a possible implementation manner, a configuration center receives an information acquisition request sent by a target internet of things device through a wired or wireless network, wherein the configuration center is located in an internet of things platform.
Step 403, the internet of things platform searches for gateway group information from the first relation table according to the device information, and the first relation table stores a corresponding relation between the internet of things device and the gateway group.
In a possible implementation manner, the configuration center stores a correspondence table between the internet of things device and the gateway group, a correspondence table between the gateway group and the gateway device, and the like.
Schematically, the corresponding relationship between the internet of things device and the gateway group is shown in table one; the corresponding relationship between the gateway group and the gateway device is shown in table two.

Gateway 4 37X8QCJ46FRB8XPGJ6RKRHYT76TH Gateway group 2 192.168.2.254
In a possible implementation manner, when a configuration center receives an information acquisition request of a target internet of things device, namely, an equipment ID, equipment summary information, an encryption algorithm and the like of the target internet of things device are acquired, firstly, an equipment key corresponding to the equipment ID is found in a table I according to the equipment ID, the found equipment key is encrypted according to the encryption algorithm, target equipment summary information is generated and matched with the received equipment summary information, and if the matching is successful, the target internet of things device is determined to be legal; therefore, gateway group information corresponding to the equipment ID, namely the gateway group ID, is determined in the first table according to the equipment ID, gateway equipment information associated with the gateway group is searched in the second table according to the gateway group ID, and then the gateway ID and the gateway address are obtained.
And step 404, the internet of things platform sends the searched gateway group information to the target internet of things equipment.
In a possible implementation manner, the configuration center finds gateway group information corresponding to the target internet of things device, that is, gateway information of the gateway device indirectly associated with the target internet of things device, and sends the gateway information to the target internet of things device, where the gateway information may include a gateway ID, a gateway address, and the like.
Step 405, the target internet of things device receives gateway group information sent by the internet of things platform.
In one possible implementation, the target internet of things device receives the gateway group information sent by the configuration center through a wired or wireless network. Alternatively, the gateway group information may include a gateway ID, a gateway address, and the like.
In step 406, the target internet of things device sends device data to the internet of things platform through a first gateway device of the at least two candidate gateway devices.
In a possible implementation manner, before the target internet of things device sends the device data to the internet of things platform, a device access request needs to be sent to the internet of things platform through the first gateway device, and only after the device access request passes verification, the target internet of things device can continue to send the device data to the internet of things platform through the first gateway device.
Illustratively, the target internet of things device sends a device access request to the internet of things platform through the first gateway device, where the device access request may include a device ID and device digest information of the target internet of things device, and an encryption algorithm for generating the device digest information.
Optionally, after the gateway device is turned on, a long-term connection is established with the internet of things platform in advance. Illustratively, the gateway device sends a connection request to the internet of things platform, where the connection request may include a gateway ID of the gateway device, gateway digest information, and an encryption algorithm for generating the gateway digest information; when the Internet of things platform receives the connection request sent by the gateway equipment, the gateway key is obtained by going to a configuration center according to the gateway ID in the connection request, so that the gateway key is encrypted according to an encryption algorithm in the connection request, target gateway abstract information is generated and matched with the gateway abstract information in the connection request, if the matching is successful, the gateway equipment is determined to be legal, and the gateway equipment is allowed to establish connection with the Internet of things platform.
Optionally, if the internet of things platform does not receive the device data sent by the gateway device within the preset time period, the connection with the gateway device may be disconnected. The preset time period may be set manually, for example, 1h.
Step 407, the internet of things platform receives device data sent by the target internet of things device through the first gateway device.
In a possible implementation manner, when the internet of things platform receives a device access request sent by a target internet of things device through a first gateway device, the device access request is verified, and after the verification is passed, a request passing message is sent to the target internet of things device through the first gateway device, and a subsequent target internet of things device can continue to send device data through the first gateway device.
Illustratively, after receiving a device access request, an internet of things platform first searches for relevant information according to a device ID of a target internet of things device in the device access request, where the relevant information may include a device key of the target internet of things device, gateway group information corresponding to the target internet of things device, and gateway information; after the relevant information is acquired, the device access request is verified, and the verification process may be divided into the following steps:
1. and verifying the equipment information of the target Internet of things equipment, namely determining whether the target Internet of things equipment is legal or not.
In a possible implementation manner, the processes of receiving the device access request and verifying the device access request can be performed in an access center in the platform of the internet of things, that is, the access center generates target device digest information according to the searched device key and an encryption algorithm in the access request, matches the target device digest information with the device digest information in the device access request, and if the matching is successful, the device information is verified to be passed.
2. And verifying the corresponding relation between the target Internet of things equipment and the first gateway equipment.
In one possible implementation, since the first gateway device has established a long-term connection with the internet of things platform before sending the device access request, when the target internet of things device sends the device access request to the internet of things platform through the first gateway device, the internet of things platform may determine that the device access request is sent by the first gateway device; when the access center acquires gateway group information and gateway information corresponding to the target internet of things device, namely whether the gateway information contains the gateway information of the first gateway device is determined, and if yes, the corresponding relation between the target internet of things device and the first gateway device is determined to be verified.
After the verification passes in the two aspects, the internet of things platform sends a request passing message to the target internet of things device through the first gateway device, and therefore the target internet of things device can continue to send device data through the first gateway device.
Step 408, when the device data transmission fails, the target internet of things device determines a second gateway device from the at least two candidate gateway devices, where the second gateway device is different from the first gateway device.
Step 305 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
And step 409, the target Internet of things equipment sends an equipment access request to the Internet of things platform through the second gateway equipment.
The device connection request may include device information of the target internet of things device, and optionally, the device information may include a device ID of the target internet of things device, device digest information, and an encryption algorithm used to generate the digest information.
In a possible implementation manner, the target internet of things device sends the device ID and the device digest information of the target internet of things device, and an encryption algorithm used for generating the digest information, to the internet of things platform through the second gateway device.
Step 410, the internet of things platform receives a device access request sent by the target internet of things device through the second gateway device.
In a possible implementation manner, the access center receives the device access request sent by the target internet of things device through the second gateway device, and the access center is located in the internet of things platform.
The device access request may include device information of the target internet of things device, that is, a device ID and device digest information of the target internet of things device, and an encryption algorithm used to generate the digest information.
Step 411, the internet of things platform searches a gateway group to which the second gateway device belongs from a second relation table according to the gateway information of the second gateway device, and the second relation table stores a corresponding relation between the gateway device and the gateway group.
Because the second gateway device establishes a long-term connection with the internet of things platform in advance, the internet of things platform can determine that the sender of the device access request is the second gateway device, so that gateway information of the second gateway device is obtained, and the gateway information can include a gateway ID.
In a possible implementation manner, the internet of things platform searches the gateway group associated with the second gateway device from the second relation table according to the gateway information of the second gateway device. Illustratively, if the gateway ID of the second gateway device is gateway 1, it can be known from table two that the gateway group corresponding to gateway 1 is gateway group 1.
Step 412, when the internet of things platform determines that the gateway group to which the second gateway device belongs corresponds to the target internet of things device according to the first relation table and the device information, sending a request passing message to the target internet of things device through the second gateway device.
In a possible implementation manner, when the internet of things platform determines gateway group information corresponding to the second gateway device, whether a gateway group to which the second gateway device belongs corresponds to the device information of the target internet of things device is determined according to the first relation table and the device information, and if so, request passing information is sent to the target internet of things device through the second gateway device.
Illustratively, if the device ID of the target internet of things device is device 1, and the gateway group to which the second gateway device belongs is gateway group 1, it can be known from table one that there is a corresponding relationship between device 1 and gateway group 1, it is determined that the gateway group to which the second gateway device belongs corresponds to the target internet of things device.
Optionally, the device information of the target internet of things device needs to be checked, and step 407 may be referred to in the checking process, which is not described herein again in this embodiment.
In a possible implementation manner, when the device information of the target internet of things device passes verification and it is determined that the gateway group to which the second gateway device belongs corresponds to the target internet of things device, the second gateway device sends request passing information to the target internet of things device.
Step 413, when the target internet of things device receives the request passing message sent by the internet of things platform, sending device data to the internet of things platform through the second gateway device.
In a possible implementation manner, after the target internet of things device receives the request passing message, the device data may continue to be sent to the internet of things platform through the second gateway device.
In this embodiment, the corresponding relationship between the internet of things device and the gateway group and the corresponding relationship between the gateway device and the gateway group are stored in the configuration center of the internet of things platform in advance, so that the corresponding gateway group information can be acquired when the internet of things device is online, and a subsequent process of determining the gateway device is performed; in addition, the target internet of things equipment can be ensured to send equipment data through the corresponding gateway equipment through the verification of the equipment access request sent by the target internet of things equipment.
When the first gateway device fails, the internet of things devices connected to the first gateway device are randomly allocated to other candidate gateway devices in the gateway group, for example, the second gateway device, because the load of the gateway device has a limit, in order to reasonably allocate resources of each gateway device, after the target internet of things device determines that the first gateway device recovers the available state, the target internet of things device may reestablish a connection with the first gateway device.
Referring to fig. 5, a flowchart illustrating a method for a target internet of things device to reestablish a connection with a first gateway device in an embodiment of the present application is shown, where the method includes:
step 501, a target internet of things device sets a preset identifier and a timer for a first gateway device, wherein the preset identifier is used for representing that the first gateway device is in an unavailable state.
The target Internet of things equipment stores gateway group information associated with the target Internet of things equipment, namely candidate gateway equipment information, and the first gateway equipment is any one of the candidate gateway equipment.
The preset identifier may be a special identifier, for example, a flag is set after the device ID of the first gateway device, or the device information of the first gateway device is stored in a blacklist.
In a possible implementation manner, when the target internet of things device determines that the first gateway device is faulty, a preset identifier and a timer are set for the first gateway device, where a duration of the timer is preset by a developer, for example, the duration of the timer is 10 minutes.
Optionally, the timer starts timing when it is determined that the first gateway device fails.
Step 502, when the timer reaches the timer duration, the target internet of things device sends device data to the first gateway device according to the preset identifier.
In a possible implementation manner, when the timer reaches the timer duration, the target internet of things device sends device data to the first gateway device according to the preset identifier. Illustratively, when the target internet of things device determines that the first gateway device fails, device data is sent to the first gateway device 10 minutes later.
Step 503, if the device data is successfully sent, the target internet of things device clears the preset identifier, and sends the device data to the internet of things platform through the first gateway device again.
In a possible implementation manner, if the device data is successfully sent, it is determined that the first gateway device has recovered to an available state, and at this time, the target internet of things device may clear the preset identifier, or extract the device information of the first gateway device from a blacklist, and send the device data to the internet of things platform through the first gateway device again.
Optionally, if the device data is not successfully transmitted for N consecutive times, it is determined that the first gateway device is still in the unavailable state, and the device data is continuously transmitted through other candidate gateway devices. And resetting the timer so as to continuously determine whether the state of the first gateway device is an available state when the timer reaches a preset time length.
In this embodiment, after the first gateway device fails, the target internet of things device attempts to send device data through the first gateway device by setting the preset identifier and the timer for the first gateway device and after the timer reaches the set time length, so that the target internet of things device can timely know the state of the first gateway device, and when the first gateway device recovers to an available state, the device data continues to be sent through the first gateway device, and reasonable allocation and utilization of gateway device resources can be achieved.
Because the internet of things platform can monitor the use state of each gateway device in real time, in a possible implementation manner, the device recovery message of the failed gateway device can be issued through the internet of things platform.
Referring to fig. 6, a flowchart illustrating a method for a target internet of things device to reestablish a connection with a first gateway device in another embodiment of the present application is shown, where the method includes:
step 601, setting a preset identifier for the first gateway device, where the preset identifier is used to represent that the first gateway device is in an unavailable state.
The implementation of this step may refer to step 501, which is not described herein.
Step 602, the internet of things platform sends an equipment recovery message to the target internet of things equipment through the second gateway equipment, where the equipment recovery message includes gateway information of the recovered gateway equipment.
In a possible implementation manner, when the internet of things platform monitors that the first gateway device has recovered to an available state, the device recovery message may be sent to the target internet of things device through the second gateway device, where the second gateway device is the gateway device that reestablishes the connection when the target internet of things device determines that the first gateway device has failed.
Optionally, the gateway information may include a gateway ID, a gateway address, and the like of the gateway device.
Step 603, when the target internet of things device receives the device recovery message sent by the internet of things platform, acquiring gateway information of the recovered gateway device contained in the device recovery message.
In a possible implementation manner, when the target internet of things device receives the device recovery message through the second gateway device, gateway information of the recovered gateway device, that is, a gateway ID, a gateway address, and the like of the gateway device, is obtained.
In step 604, if the recovered gateway device is the first gateway device including the preset identifier, the preset identifier is cleared.
In a possible implementation manner, when the target internet of things device acquires gateway information of a recovered gateway device, the gateway information is matched with device information of a first gateway device containing a preset identifier, which is stored in the target internet of things device, and if the matching is successful, it is determined that the first gateway device is recovered to be in an available state, and at this time, the target internet of things device may clear the preset identifier of the first gateway device.
Optionally, if the device information of the first gateway is not matched in the acquired gateway information of the recovered gateway device, it is determined that the first gateway device is still in the unavailable state.
Step 605, if the device data transmission fails, preferentially selecting to transmit the device data to the internet of things platform through the first gateway device.
In a possible implementation manner, in the process that the target internet of things device sends the device data through the second gateway device, the second gateway device fails to send the device data, and at this time, since the target internet of things device determines that the first gateway device is restored to the available state, the first gateway device may preferentially select to send the device data to the internet of things platform.
In this embodiment, the service state of the gateway device is monitored in real time through the internet of things platform, and if it is monitored that a certain gateway device is recovered from an unavailable state to an available state, the device recovery message is sent to the target internet of things device through the rest candidate gateway devices, so that the target internet of things device can know the service state of the first gateway device in time; in addition, if the target internet of things device determines that the first gateway device is recovered to be in the available state, when the second gateway device fails, the first gateway device can be preferentially selected to send device data to the internet of things platform, the step of randomly selecting the gateway device is avoided, and the efficiency of switching the gateway device is improved.

(4) The internet of things device sends a device access request to the access center 703 through the gateway device 2, where the device access request includes the device ID of the internet of things device 1, device digest information, and an encryption algorithm for generating the device digest information.
(5) And after the access center 703 receives the device access request, the device access request is verified. Illustratively, the access center 703 acquires the device information, the correspondence between the internet of things device 1 and the gateway group, the correspondence between the gateway group and the gateway device, and the like from the configuration center according to the device ID of the internet of things device 1 in the device access request.
(6) When it is determined that the device information of the internet of things device 1 passes verification and the gateway group to which the internet of things device 1 and the gateway device 2 belong corresponds, the access center 703 sends request passing information to the internet of things device 1 through the gateway device 2, so that the internet of things device 1 sends device data to the internet of things platform 701 through the gateway device 2 after receiving the request passing information.
In a possible implementation manner, when the internet of things device 1 does not successfully transmit the device data through the gateway device 2N times continuously, it is determined that the gateway device 2 fails, and the internet of things device 1 and the internet of things device 3 cannot normally communicate with the internet of things platform 701, at this time, the internet of things device 1 may automatically reconnect to the remaining available gateway devices in the gateway group 1, for example, the gateway device 3, according to the gateway group information obtained from the configuration center, that is, according to the correspondence between the internet of things device 1 and the gateway group 1 shown in table 1 and the correspondence between the gateway group and the gateway device shown in table 2, and perform the verification of the device access request again, and after the verification of the device access request is completed, the internet of things device 1 may communicate with the internet of things platform 701 again through the gateway device 3.
