Description

Technical Field

[0001] Embodiments of the present invention relate to the field of communications, and more particularly, to a method, apparatus, storage medium, and electronic device for data transmission. Background Art

[0002] In the related art, usually two identical gateways are in operation at the same time. One gateway is a normal working gateway that collects and reports data in real time to a controller, and the other gateway is in a standby state and does not participate in data collection. When the working gateway fails, the standby gateway enters the working state to complete the switchover. However, the standby gateway needs to go through processes such as device registration and gateway registration when switching to the normal working state, which takes a long time.

[0003] It can be seen that there is a technical problem in the related art that the switchover from the primary gateway to the standby gateway takes a long time.

[0004] In view of the above problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0005] Embodiments of the present invention provide a method, apparatus, storage medium, and electronic device for data transmission, so as to at least solve the problem in the related art that the switchover from the primary gateway to the standby gateway takes a long time.

[0007] In an exemplary embodiment, before controlling the second process to send the data information to the third process, the method further includes: determining a load state of a third gateway that has established a backup candidate relationship with the first gateway; determining a fourth gateway that meets a predetermined condition from the third gateways based on the load state; in a case where the number of the fourth gateways is multiple, sorting the fourth gateways to obtain a target sorting result, and determining the second gateway from the fourth gateways based on the target sorting result.

[0008] In an exemplary embodiment, determining the load status of a third gateway that establishes a backup candidate relationship with the first gateway includes: obtaining target information at a predetermined time period, where the target information includes at least one of the following: the processor utilization rate of the third gateway, the memory usage rate of the third gateway, the number of backup gateways allowed to be the backup gateway of the third gateway, the network signal strength of the third gateway, the number of sub-devices of the third gateway, and the number of historical failures of the third gateway; determining the obtained target information as the load status.

[0009] In an exemplary embodiment, determining a fourth gateway that meets a predetermined condition from the third gateways based on the load status includes: determining the processor utilization rate included in the load status, and determining a fifth gateway as the gateway whose processor utilization rate included in the third gateway is less than a first preset threshold; determining the memory usage rate of the fifth gateway included in the load status, and determining a sixth gateway as the gateway whose memory usage rate is less than a second preset threshold; determining the number of backup gateways allowed to be the backup gateway of the sixth gateway included in the load status, and determining a seventh gateway as the gateway whose number of backup gateways is greater than a third preset threshold; determining the network signal strength of the seventh gateway included in the load status, and determining the fourth gateway as the gateway whose network signal strength is greater than a fourth preset threshold.

[0010] In an exemplary embodiment, sorting the fourth gateway to obtain a target sorting result includes: determining the number of sub-devices of the fourth gateway included in the load status, and sorting the fourth gateway according to the number of sub-devices to obtain an initial sorting; determining the number of historical failures of the fourth gateway included in the load status, and adjusting the initial sorting according to the number of historical failures to obtain the target sorting result.

[0011] In an exemplary embodiment, after controlling the second process to send the data information to the third process, the method further includes: receiving feedback data sent by the second gateway, where the feedback data is data obtained by the target platform processing the data information; storing the feedback data.

[0012] In an exemplary embodiment, after storing the feedback data, the method further includes: when the target state changes from the abnormal state to the normal state, controlling the second process to send the feedback data to the first process.

[0013] According to another embodiment of the present invention, there is provided a data transmission device, including: a determination module, configured to determine a target state of a first process in a first gateway, where the first gateway is connected to a target platform through the first process; a first sending module, configured to, when the target state indicates that the first process is in an abnormal state, send data information of a device connected to the first gateway to a second process in the first gateway; a second sending module, configured to control the second process to send the data information to a third process, so as to instruct the third process to send the data information to the target platform, where the third process is a process in a second gateway that allows data transmission with the second process, and the second gateway is connected to the target platform through the third process.

[0014] According to still another embodiment of the present invention, there is also provided a computer-readable storage medium, in which a computer program is stored, where the computer program is configured to execute the steps in any one of the above method embodiments when running.

[0015] According to still another embodiment of the present invention, there is also provided an electronic device, including a memory and a processor, where a computer program is stored in the memory, and the processor is configured to run the computer program to execute the steps in any one of the above method embodiments.

[0016] According to still another embodiment of the present invention, there is also provided a computer program product, including a computer program, where the steps of the methods described in various embodiments of the present application are implemented when the computer program is executed by a processor.

[0017] Through the present invention, the target state of the first process in the first gateway connected to the target platform can be determined. When the target state indicates that the first process is in an abnormal state, the data information of the device connected to the first gateway can be sent to the second process of the first gateway, and the second process can be controlled to send the data information to the third process in the second gateway, instructing the third process to send the data information to the target platform. Since both the first gateway and the second gateway can work normally independently, when the first gateway is in an abnormal state, the second gateway can directly replace the first gateway for data transmission, that is, the data information of the device connected to the first gateway can be sent to the same target platform through the third process in the second gateway that has already established a data transmission relationship with the first gateway, without the device connected to the first gateway needing to re-establish a data transmission relationship, reducing the switching time. Therefore, the problem of long time consumption in switching the main gateway to the standby gateway in the related art can be solved, achieving the effect of shortening the switching time between the main and standby gateways so that the main gateway can seamlessly switch to the standby gateway.

[0027] In the following, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0029] The method embodiments provided in the embodiments of the present application can be executed on a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 is the hardware structure block diagram of a mobile terminal for a data transmission method according to an embodiment of the present invention. As Figure 1 shown, the mobile terminal may include one or more ( Figure 1Only one processor 102 is shown (the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. Among them, the above mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those of ordinary skill in the art can understand that Figure 1 The structure shown is only illustrative and does not limit the structure of the above mobile terminal. For example, the mobile terminal may further include more or fewer components than Figure 1 shown therein, or have a different configuration from Figure 1 shown.

[0030] The memory 104 can be used to store computer programs. For example, software programs and modules of application software, such as the computer program corresponding to the data transmission method in the embodiments of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, implements the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some instances, the memory 104 may further include a memory remotely disposed relative to the processor 102, and these remote memories can be connected to the mobile terminal through a network. Examples of the above network include, but are not limited to, the Internet, an enterprise intranet, a local area network, a mobile communication network, and combinations thereof.

[0031] The transmission device 106 is used to receive or send data via a network. Specific examples of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one instance, the transmission device 106 includes a network adapter (abbreviated as NIC), which can be connected to other network devices through a base station and thus communicate with the Internet. In one instance, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0032] In this embodiment, a data transmission method is provided. Figure 2 is a flowchart of the data transmission method according to the embodiments of the present invention, as Figure 2 shown, and the process includes the following steps:

[0033] Step S202, determining the target state of the first process in the first gateway, where the first gateway is connected to the target platform through the first process;

[0034] Step S204, when the target state indicates that the first process is in an abnormal state, send the data information of the device connected to the first gateway to the second process in the first gateway;

[0035] Step S206, control the second process to send the data information to the third process, so as to instruct the third process to send the data information to the target platform, where the third process is a process in the second gateway that allows data transmission with the second process, and the second gateway is connected to the target platform through the third process.

[0036] In the above embodiment, the gateway can be understood as a link connecting the sensing network and the traditional communication network, which can realize protocol conversion between the sensing network and the communication network, different types of sensing networks, and can also realize wide-area interconnection and local-area interconnection. For the specific structures of the first gateway and the second gateway, reference can be made to Figure 3 , Figure 3 which is a schematic diagram of the gateway backup system according to the embodiment of the present invention. As Figure 3 shown, the first gateway can be the main gateway A, and the second gateway can be the standby gateway B. Both the first gateway and the second gateway need to include a daemon process, a main process, a secondary process, and an access process. The access process also needs to perform data transmission with multiple sub-devices and can receive data sent from multiple sub-devices. The first gateway and the second gateway are gateways that can independently complete data transmission with the target platform in the normal working state and both have redundant backup functions. Among them, a process can be understood as the execution process of a program.

[0037] In the related art, each main gateway needs to set a standby gateway, and when the main gateway fails, the standby gateway is enabled. For example, when the number of main gateways is 1000, 1000 standby gateways are required, that is, 2000 gateways need to be set. In this embodiment, however, the first gateway and the second gateway can be parallel gateways. Both the first gateway and the second gateway can be used as independent gateways to connect different sub-devices and send the data of different sub-devices to the target platform. That is, only 1000 gateways need to be set. The gateways included in the 1000 gateways can back up each other, and there is no need to set dedicated standby gateways. By adding a backup function to the gateways in the working state, the number of backup gateways can be reduced by half. There is no need for 1000 additional backup gateways, and only 1000 gateways are required to achieve seamless switching between the main and standby gateways, and the usage cost of the device can be greatly reduced.

[0038] In the above embodiment, the main process can be responsible for most of the tasks in the gateway, such as connecting with the target platform, scheduled tasks, or adding, deleting, modifying, and checking sub-devices with which data transmission relationships are established, but not limited thereto. The auxiliary process can be responsible for connecting with other gateways, and the two gateways that have established connections can serve as backup gateways for each other. When the main process of one of the gateways is abnormal, the service can be quickly sent to the backup gateway. The access process can be responsible for the access of multiple sub-devices, and can establish data transmission relationships with the main process and the auxiliary process in a multi-process manner to transmit messages and data. The daemon process can be responsible for detecting other processes, and can quickly restart the process when other processes are abnormal.

[0039] In the above embodiment, when the first gateway and the second gateway are in normal working state, the main process in the first gateway (i.e., the above-mentioned first process) can be connected to the cloud platform (i.e., the above-mentioned target platform), and the access process can establish a data transmission relationship between multiple processes with the main process and the auxiliary process, and can also establish a data transmission relationship with multiple sub-devices, and can send data information in multiple sub-devices to the first process, so as to send the data information to the target platform through the first process. The auxiliary process in the first gateway (i.e., the above-mentioned second process) can establish a data transmission relationship with the main process in the second gateway (i.e., the above-mentioned third process), that is, establish a backup relationship, and can be connected through transmission links such as wifi, 4G / 5G, etc., to avoid the wired network used by the main process, and can avoid the auxiliary process from being paralyzed at the same time when the main process network fails.

[0040] In the above embodiment, when the daemon process in the first gateway determines that the target state of the first process is abnormal, the first process can be restarted. In addition, when the access process in the first gateway detects that the first process is abnormal, the data transmission relationship between the main process, the auxiliary process and the access process will change. Figure 4 is a schematic diagram of the data transmission relationship between processes when the main process is abnormal according to an embodiment of the present invention, such as Figure 4 As shown, under normal working conditions, the data transmission state of establishing a primary data transmission relationship with the first process and an auxiliary data transmission relationship with the second process will switch to a data transmission state of establishing an auxiliary data transmission relationship with the first process and a primary data transmission relationship with the second process. Among them, the abnormal state can be a freeze, a memory leak, or a failure to connect to the network with the target platform, etc., but is not limited to this. The process whose data transmission state is the primary connection can be understood as a process that receives data information from the connected device (that is, when the first process is in an abnormal state, the second process can receive data information sent by the access process).

[0041] In the above embodiments, the second gateway may proxy the first gateway to forward messages. After receiving the data information, the second process may send the data information to the main process (i.e., the above-mentioned third process) in the second gateway that has established a data transmission relationship with the first gateway. After receiving the data information, the third process may add the identifier of the first gateway to the data message and forward it to the target platform, so as to forward the data information in the first gateway to the same target platform.

[0042] Through the present invention, the target state of the first process in the first gateway connected to the target platform can be determined. When the target state indicates that the first process is in an abnormal state, the data information of the device connected to the first gateway can be sent to the second process in the first gateway, and the second process can be controlled to send the data information to the third process in the second gateway, instructing the third process to send the data information to the target platform. Since both the first gateway and the second gateway can work independently and normally, when the first gateway is in an abnormal state, the second gateway can directly replace the first gateway to perform data transmission, that is, the data information of the device connected to the first gateway can be sent to the same target platform through the third process in the second gateway that has already established a data transmission relationship with the first gateway, without the need for the device connected to the first gateway to re-establish a data transmission relationship, reducing the switching time. Therefore, the problem of long time consumption in switching the main gateway to the standby gateway in the related art can be solved, achieving the effect of shortening the switching time between the main and standby gateways so that the main gateway can seamlessly switch to the standby gateway.

[0043] Optionally, the execution subject of the above steps may be a background processor, a server, or a terminal, but is not limited thereto.

[0044] In an exemplary embodiment, before controlling the second process to send the data information to the third process, the method further includes: determining the load status of the third gateway that has established a backup candidate relationship with the first gateway; determining a fourth gateway that meets a predetermined condition from the third gateways based on the load status; when the number of the fourth gateways is multiple, sorting the fourth gateways to obtain a target sorting result, and determining the second gateway from the fourth gateways based on the target sorting result.

[0045] In the above embodiments, after the system is initialized, the load status of multiple third gateways that are adjacent to the first gateway and establish candidate backup relationships can be obtained through methods such as the gateway search protocol and user specification. The fourth gateway that meets the predetermined conditions among the multiple third gateways can be determined based on the load status of the gateways. The load capabilities of the multiple gateways in the fourth gateway can be sorted in descending order to obtain the target sorting result. The gateway ranked first or the top two in the target sorting result can be determined as the second gateway, that is, the second gateway can be one or multiple, and can be determined according to the actual load status of the gateway. Among them, the predetermined condition can be that the load status is less than 70% or 50% of the maximum load capacity, but is not limited thereto.

[0046] In an exemplary embodiment, determining the load status of the third gateway that establishes a backup candidate relationship with the first gateway includes: obtaining target information according to a predetermined time period, where the target information includes at least one of the following: the processor utilization rate of the third gateway, the memory usage rate of the third gateway, the number of backup gateways allowed to be the backup gateway of the third gateway, the network signal strength of the third gateway, the number of sub-devices of the third gateway, and the historical failure times of the third gateway; determining the obtained target information as the load status.

[0047] In the above embodiments, the gateways can exchange parameters within a predetermined time period. Figure 5 It is a schematic diagram of a gateway group according to an embodiment of the present invention. As Figure 5 shown, the multiple third gateways that are adjacent to the first gateway and establish candidate backup relationships can be gateway B, gateway C, gateway D, and gateway E. The first gateway and the multiple third gateways can regularly communicate the load status of the gateways (that is, exchange target information within the above-mentioned predetermined time period). The target information for interaction can include the number of sub-devices, the gateway processor utilization rate, the gateway memory usage rate, the signal strength of the connection between gateways, the number of backup gateways allowed to be the backup gateway (that is, the number of gateways allowed to receive minus the number of gateways already received), and the historical failure times (for example, the number of times the gateway crashes in the past 24 hours, or the number of times the gateway crashes in the past 48 hours). The load status can be determined by the target information including the processor utilization rate, the memory usage rate, the number of backup gateways allowed to be the backup gateway, the network signal strength, the number of sub-devices, and the historical failure times to determine the second gateway that can establish a backup relationship with the first gateway among the third gateways. Among them, the predetermined time period can be 1 minute or 5 minutes, and the present invention does not limit this.

[0048] In an exemplary embodiment, determining a fourth gateway that meets a predetermined condition from the third gateways based on the load status includes: determining the processor utilization rate included in the load status, and determining a fifth gateway from the third gateways where the processor utilization rate is less than a first preset threshold; determining the memory usage rate of the fifth gateway included in the load status, and determining a sixth gateway where the memory usage rate is less than a second preset threshold; determining the number of backup-capable gateways that are allowed to be the backup gateways of the sixth gateway included in the load status, and determining a seventh gateway where the number of backup-capable gateways is greater than a third preset threshold; determining the network signal strength of the seventh gateway included in the load status, and determining the fourth gateway where the network signal strength is greater than a fourth preset threshold.

[0049] In the above embodiment, the flowchart for determining the backup gateway can be seen in Figure 6 , Figure 6 is the flowchart of the gateway backup load balancing solution according to the embodiment of the present invention. The process includes:

[0050] S602, interacting with gateway backup parameters;

[0051] S604, determining whether the CPU is overloaded. If it exceeds the threshold, execute step S616. If it does not exceed the threshold, execute step S606;

[0052] S606, determining whether there is free memory. If it exceeds the threshold, execute step S616. If it does not exceed the threshold, execute step S608;

[0053] S608, determining the number of backup-capable gateways. If the number of backup-capable gateways is full, execute step S616. If the number of backup-capable gateways is not full, execute step S610;

[0054] S610, determining the network signal strength. If it is lower than the threshold, execute step S616. If it is not lower than the threshold, execute step S612;

[0055] S612, sorting the backup gateways;

[0056] S614, uploading the gateway backup relationship to the cloud platform;

[0057] S616, not including it in the backup gateway list.

[0058] In the above embodiments, it is possible to first determine the gateway CPU load in the third gateway (i.e., the above-mentioned processor utilization rate), determine the gateway with a processor utilization rate less than the first preset threshold as the candidate gateway after the first screening (i.e., the above-mentioned fifth gateway), and do not include the gateway with a processor utilization rate greater than the first preset threshold in the list of backup gateways. Among them, the first preset threshold can be a processor utilization rate of 70%, or a processor utilization rate of 75%, but is not limited thereto. After excluding the gateways with a relatively high processor utilization rate, it is possible to continue to determine the free memory of the gateways in the fifth gateway (i.e., the above-mentioned memory utilization rate), determine the gateway with a memory utilization rate less than the second preset threshold in the fifth gateway as the candidate gateway after the second screening (i.e., the above-mentioned sixth gateway), and do not include the gateway with a memory utilization rate greater than the second preset threshold in the list of backup gateways. Among them, the second preset threshold can be 5M of memory, or 10M of memory, etc. Since the number of sub-devices in the gateway and operations such as regularly turning on and off the sub-devices will affect the memory, the second preset threshold can be determined according to the actual situation, and the present invention does not limit this. It is possible to determine the number of backup gateways that can be used as backup gateways included in the sixth gateway, and determine the gateway with the number of backup gateways greater than 0 (i.e., the above-mentioned third preset threshold) as the candidate gateway after the third screening (i.e., the above-mentioned seventh gateway). If the number of backup gateways is equal to 0, it can be stated that there are other backup gateways, and then this gateway is not included in the list of backup gateways. It is also possible to determine the network signal strength of the gateways included in the seventh gateway, determine the gateway with a network signal strength greater than the fourth preset threshold as the fourth gateway, and do not include the gateway with a network signal strength less than the fourth preset threshold in the list of backup gateways. Among them, the fourth preset threshold can be set according to different networks. For example, when connecting through WIFI, the fourth threshold can be -70dBm, or -65dBm, etc. When connecting through 5G / 4G, the fourth preset threshold can be -60dBm, or -50dBm, etc., and the present invention does not limit this.

[0059] In an exemplary embodiment, sorting the fourth gateway to obtain a target sorting result includes: determining the number of sub-devices of the fourth gateway included in the load status, sorting the fourth gateway according to the number of sub-devices to obtain an initial sorting; determining the historical failure times of the fourth gateway included in the load status, and adjusting the initial sorting according to the historical failure times to obtain the target sorting result.

[0060] In the above embodiments, the number of sub-devices connected to the gateways included in the fourth gateway can be determined, and the gateways corresponding to the number of sub-devices can be sorted in reverse order to obtain an initial sorting, that is, the fewer the number of sub-devices connected to the gateway, the higher the ranking, and the more the number of sub-devices connected to the gateway, the lower the ranking. The initial sorting can also be adjusted by the number of historical failures, that is, for each historical failure that occurs within a preset period for the gateways included in the fourth gateway, the sorting is adjusted one position backward to obtain the final target sorting result. The preset period can be related to the number of positions adjusted backward, that is, if a failure occurs within the past hour, the sorting of the corresponding gateway can be adjusted 2 positions backward; if a failure occurs within the past 24 hours, the sorting of the corresponding gateway can be adjusted 1 position backward, and so on. Example: When the fourth gateway includes gateway B, gateway C, gateway D, and gateway E, and the initial sorting is gateway B, gateway C, gateway D, gateway E, if gateway B has a failure within the past 1 hour, then gateway B in the initial sorting is adjusted 2 positions backward, and the target sorting result that can be obtained is gateway C, gateway D, gateway B, gateway E; if gateway C has a failure within the past 24 hours, then the sorting of gateway C can be adjusted 1 position backward, and the target sorting that can be obtained is gateway D, gateway C, gateway B, gateway E. After determining the gateway backup order, if the final target sorting result is gateway B, gateway C, gateway D, gateway E, then gateway A can select gateway B as the first backup gateway and gateway C as the second backup gateway. After the cloud platform obtains the gateway backup relationship, it can record it and support processing gateway A messages in the messages reported by gateway D and gateway C.

[0061] In an exemplary embodiment, after controlling the second process to send the data information to the third process, the method further includes: receiving feedback data sent by the second gateway, where the feedback data is the data obtained by the target platform processing the data information; storing the feedback data.

[0062] In the above embodiments, at the target platform level, the target platform can select the first gateway and the second gateway to establish a backup relationship at the target platform. When the first gateway fails, the data information of the first gateway can be uploaded to the target platform through the third process in the second gateway. After the target platform receives the data information about the first gateway reported by the third process, it can set the first gateway to the offline state, and send the feedback data that needs to be sent to the first gateway to the second gateway. The third process in the second gateway can send the feedback data to the second process in the first gateway, and the second process can use the queue to cache the feedback data. The target platform can also choose to still send the feedback data to the first gateway. Since the first gateway cannot receive the messages from the target platform at this time, the feedback data sent by the target platform to the first gateway will be lost.

[0063] In the above embodiments, the target platform may also select not to establish a backup relationship between the first gateway and the second gateway on the target platform, and only parse and process other gateway messages reported by a certain gateway. For example, in the data message reported by gateway B, the target platform can parse the data message to identify the message of gateway A, and then determine that this data message belongs to gateway A, and then process the data message of gateway A. However, since no backup relationship is established, the feedback data of the target platform will not be sent to the second gateway, and the first gateway will not receive the feedback message either.

[0064] In an exemplary embodiment, after storing the feedback data, the method further includes: when the target state changes from the abnormal state to the normal state, controlling the second process to send the feedback data to the first process.

[0065] In the above embodiments, after the first process restarts and completes, it can re - establish a connection with the target platform and re - establish a data transmission relationship with the access process. The data transmission relationships among the main process, the auxiliary process, and the access process will return to the data transmission relationships in the normal working state. Figure 7 It is a schematic diagram of the inter - process data transmission when the main process is normal according to an embodiment of the present invention, as Figure 7 shown. The access process sets the data transmission relationship with the first process as the main data transmission relationship and the data transmission relationship with the second process as the auxiliary data transmission relationship. When the second process detects that the first process has resumed normal operation, it can actively establish a data transmission relationship with the first process and send the cached feedback data to the first process for processing by the first gateway. At the same time, the second process can notify the third process in the second gateway that the first gateway has resumed normal operation.

[0066] The data transmission method will be described below in combination with specific embodiments:

[0067] Figure 8 It is a flowchart of the data transmission method according to a specific embodiment of the present invention, as Figure 8 shown. The process includes:

[0068] S802, system initialization;

[0069] S804, gateways establish a backup relationship;

[0070] S806, the main process of gateway A is abnormal;

[0071] S808, gateway A switches the connection to gateway B;

[0072] S810, gateway B acts as proxy for gateway A;

[0073] S812, the main process of gateway A resumes normal operation.

[0074] In the above embodiments, by establishing backup candidate relationships among multiple gateways, a backup gateway that establishes a backup relationship with the primary gateway can be selected, and the services of the faulty gateway can be transferred to the backup gateway with the lowest load, so as to reduce the impact on the entire system. In addition, through the multi-process technology, the primary gateway can establish a data transmission relationship with the primary process of the backup gateway through the secondary process, which increases the gateway backup function. The backup gateway can also establish a backup relationship with the primary gateway through the same solution. In scenarios such as industrial Internet or smart home that require multiple gateways, the gateways can form backup relationships with each other, and there is no need for a dedicated redundant backup gateway. It is also possible to strip the basic functions that are not prone to errors to the access process and the secondary process, that is, by establishing a backup data transmission relationship between two gateways, the primary gateway can have two communication links to the platform (the primary gateway communication link and the backup gateway communication link). When a failure occurs in the primary process of the primary gateway, that is, the primary gateway communication link fails, through the detection mechanism between processes, the primary gateway can immediately switch to the backup gateway communication link, avoiding the process of the sub-devices re-registering to the network and the gateway reconnecting to the platform.
