Fig. 1 is a flowchart of a gateway switching management method based on the internet of things according to an embodiment of the present disclosure, where the gateway switching management method based on the internet of things according to the embodiment of the present disclosure may be executed by a gateway switching management device based on the internet of things, and the gateway switching management device based on the internet of things may be implemented in a hardware and/or software manner and integrated in a gateway switching management device (e.g., a cloud server) based on the internet of things.
The gateway switching management method executed by the gateway switching management device based on the internet of things is described as an example. Referring to fig. 1, the gateway handover management method based on the internet of things includes:
s101: and acquiring the current information load capacity of each Internet of things gateway, and comparing the current information load capacity with a set load capacity threshold value.
The gateway switching management device (hereinafter referred to as switching management device) based on the internet of things provided by this embodiment is integrated in a cloud server, and the switching management device is in communication connection with different internet of things networks through an internet network, and a plurality of internet of things gateways are configured in each internet of things network and are connected to the cloud server through the internet network. Each internet of things gateway of the same internet of things network is connected with a plurality of internet of things terminals (such as sensing equipment, intelligent household equipment, community intelligent access control equipment, community security equipment and other internet of things equipment) in a wireless communication mode, and the internet of things terminals can communicate with the cloud server through the internet of things gateways. And the overlapping parts exist among the signal coverage ranges of a plurality of adjacent Internet of things gateways, one Internet of things terminal can detect the wireless signals of the plurality of Internet of things gateways at the installation position of the Internet of things terminal, and one wireless channel can be selected to be connected with the corresponding Internet of things gateway.
Illustratively, each internet of things gateway detects a data transmission amount (for example, a data amount transmitted within a set time period) corresponding to data uploaded to the cloud server by the gateway in real time, and uploads the corresponding data transmission amount as a current information load amount to the switching management device.
After receiving the current information load amount uploaded by each Internet of things gateway, comparing the corresponding current information load amount with a set load amount threshold value aiming at each Internet of things gateway, and generating a corresponding load amount comparison result.
S102: and based on the internet of things gateway with the current information load exceeding the load threshold, informing the internet of things gateway to initiate a signal detection request to each internet of things terminal connected with the internet of things gateway, so that each internet of things terminal determines signal intensity information corresponding to the detected internet of things gateway and returns corresponding signal detection information based on the signal intensity information.
Illustratively, when the load comparison result indicates that the current information load exceeds the load threshold, the internet of things gateway corresponding to the current information load is determined, and the internet of things gateway is notified to initiate a signal detection request to each internet of things terminal connected to the internet of things gateway.
After receiving the notification of the signal detection request initiated by the switching management device, the gateway of the internet of things determines all the terminals of the internet of things connected with the gateway of the internet of things, and initiates the signal detection request to the terminals of the internet of things. The method comprises the steps that after receiving a signal detection request, the terminal of the Internet of things determines all currently detected Internet of things gateways, determines gateway identification information of the Internet of things gateways and signal strength information corresponding to the Internet of things gateways, and returns signal detection information reflecting the gateway identification information and the signal strength information corresponding to the detected Internet of things gateways to a currently connected switching management device. After the internet of things gateway receives the signal detection information returned by each internet of things terminal, the internet of things gateway forwards each signal detection information to the switching management device.
In a possible embodiment, when the internet of things gateway notifies the internet of things gateway to initiate a signal detection request to each internet of things terminal connected to the internet of things gateway based on the fact that the current information load exceeds the load threshold, the method specifically includes: and based on the condition that the current information load exceeds the load threshold value or the current information transmission efficiency does not reach the set transmission efficiency threshold value, the Internet of things gateway informs the Internet of things gateway to initiate a signal detection request to each Internet of things terminal connected with the Internet of things gateway.
Specifically, whether a signal detection request is initiated to each currently connected internet of things terminal is determined according to a comparison result of a current information load and a load threshold, and whether an internet of things gateway is notified to initiate a signal detection request to each currently connected internet of things terminal is determined according to a comparison result of current information transmission efficiency and a transmission efficiency threshold. For example, the switching management device calculates current information transmission efficiency corresponding to data uploaded by each internet of things gateway in real time, and when the current information efficiency (e.g., 0.2Mb/s) is less than a set transmission efficiency threshold (e.g., 2Mb/s), it is considered that the connection with the corresponding internet of things gateway is abnormal, and the internet of things terminal needs to be notified to switch the gateway, and then the internet of things gateway is notified to initiate a signal detection request to each connected internet of things terminal.
S103: and determining the Internet of things gateways which can be switched by the Internet of things terminals according to the signal detection information, and determining corresponding receivable load amounts based on current information load amounts corresponding to the Internet of things gateways.
Illustratively, after receiving signal detection information corresponding to each internet of things terminal, analyzing the signal detection information to obtain gateway identification information and signal strength information corresponding to the internet of things gateway detected by each internet of things terminal.
Further, for each internet of things terminal connected with the internet of things gateway (the internet of things gateway with the current information load exceeding the load threshold), according to the identification information of each gateway and the corresponding signal strength information reflected by the signal detection information, determining other internet of things gateways for the internet of things terminal to switch. It can be understood that one internet of things terminal may correspond to one or more internet of things gateways for switching, that is, the location of the internet of things gateway may be located within the signal coverage of one or more internet of things gateways. It can be understood that, when one internet of things terminal only detects a wireless signal of a switching management device initiating a signal detection request, the returned signal detection information only reflects gateway identification information and signal strength information corresponding to the switching management device, and it is determined that there is no internet of things gateway for the internet of things terminal to switch.
After determining all the internet of things gateways for switching, initiating load detection requests to the internet of things gateways through the internet network. After receiving the load detection request, the gateway of the internet of things detects the data transmission amount corresponding to the data transmitted to the switching management device by the gateway of the internet of things, compares the corresponding data transmission amount with a set load threshold (smaller than the maximum load amount of the gateway of the internet of things and consistent with the set load amount threshold), determines the receivable load amount which can be increased on the basis of the data transmission amount (for example, the difference between the set load threshold and the data transmission amount is used as the receivable load amount), and returns the corresponding receivable load amount to the switching management device which sends the load detection request.
S104: according to the receivable load amount corresponding to each Internet of things gateway, the Internet of things terminal and the corresponding Internet of things gateway which need to be switched are determined, and the Internet of things terminal is informed to be switched to the corresponding Internet of things gateway.
Exemplarily, after the receivable load amount corresponding to each internet of things gateway is determined, the information transmission amount of each internet of things terminal currently connected to the internet of things gateway with the current information load amount exceeding the load amount threshold is determined, the internet of things gateway capable of being switched is allocated to each internet of things terminal according to the receivable load amount corresponding to each internet of things gateway and the information transmission amount of the corresponding internet of things terminal, a gateway switching indication is sent to the internet of things gateway with the current information load amount exceeding the load amount threshold, the internet of things gateway informs the internet of things terminals of being switched to the corresponding allocated internet of things gateway based on the gateway switching indication, the internet of things terminals are switched and connected to the allocated internet of things gateway, and the switched internet of things gateway is accessed into the same internet of things network.
In one possible embodiment, in the step of determining the internet of things terminals and the corresponding internet of things gateways which need to be switched, according to receivable load amounts corresponding to the internet of things gateways and information transmission amounts of the corresponding internet of things terminals, when the internet of things terminals are allocated with the internet of things gateways which can be switched, the information transmission amounts corresponding to the internet of things terminals allocated with the switchable internet of things gateways are accumulated, when the accumulated amount obtained by subtracting the information transmission amount from the current information load amount is smaller than a load amount threshold value, the internet of things gateways used for switching can be stopped being allocated to the remaining internet of things terminals, and only the internet of things terminals allocated with the internet of things gateways are notified to switch the gateways.
In one possible embodiment, in the step of determining the internet of things terminals and the corresponding internet of things gateways which need to be switched, when the internet of things terminals which can be switched are allocated for each internet of things terminal according to receivable load amounts corresponding to each internet of things gateway and information transmission amounts of the corresponding internet of things terminals, the corresponding internet of things terminals are synchronously notified to be switched to the corresponding internet of things gateways, current information load amounts are updated in real time, and when the internet of things terminals which are switched to be corresponding are switched to be smaller than a set load amount threshold value, the internet of things gateways which are used for switching can be stopped being allocated for the remaining internet of things terminals.
The above-mentioned, collect through the current information load volume to each thing networking gateway, when the current information load volume of thing networking gateway exceeded the load volume threshold value of settlement, according to the signal strength information that each thing networking terminal of thing networking gateway current connection corresponds with other thing networking gateways that detect, confirm the thing networking gateway that can supply each thing networking terminal to switch, and confirm the receivable load volume of these thing networking gateways, confirm the thing networking terminal that needs to carry out the gateway switching and the thing networking gateway that corresponds according to the receivable load volume, and inform corresponding thing networking terminal and switch to the thing networking gateway that corresponds, distribute the thing networking equipment to the thing networking gateway that has data transmission residual power, promote the data transmission quality to the thing networking equipment.
On the basis of the foregoing embodiment, fig. 2 is a flowchart of another gateway handover management method based on the internet of things according to an embodiment of the present application, which is a concrete implementation of the gateway handover management method based on the internet of things. Referring to fig. 2, the gateway handover management method based on the internet of things includes:
s201: and acquiring the current information load capacity of each Internet of things gateway, and comparing the current information load capacity with a set load capacity threshold value.
S202: and based on the internet of things gateway with the current information load exceeding the load threshold, informing the internet of things gateway to initiate a signal detection request to each internet of things terminal connected with the internet of things gateway, so that each internet of things terminal determines signal intensity information corresponding to the detected internet of things gateway and returns corresponding signal detection information based on the signal intensity information.
S203: and determining a gateway corresponding relation between the Internet of things terminal and the Internet of things gateway according to the signal detection information, and comparing the signal detection information with a set signal intensity threshold value to obtain a signal comparison result.
Specifically, after signal detection information returned by each internet of things terminal is received, gateway identification information and signal strength information carried by the signal detection information are determined, and the terminal identification information of the internet of things terminal and corresponding gateway identification information are recorded in a terminal gateway recording table, so that a gateway corresponding relation between the internet of things terminal and the internet of things gateway is established. It can be understood that one internet of things terminal may correspond to one or more internet of things gateways, that is, the location of the internet of things gateway may be located within the signal coverage of the one or more internet of things gateways, and the terminal identification information corresponds to one or more gateway identification information. And the internet of things gateways corresponding to different internet of things terminals can be completely or partially overlapped.
Further, for the signal detection information returned by each internet of things terminal, the signal strength information in the signal detection information is compared with a set signal strength threshold value to obtain a signal comparison result. It can be understood that if the signal strength information reaches the signal strength threshold, it is considered that the corresponding internet of things gateway can be stably accessed by the internet of things terminal and stably communicates with the internet of things terminal, otherwise, it is considered that the communication quality of the internet of things terminal after accessing the corresponding internet of things gateway cannot be guaranteed.
S204: and screening out the Internet of things gateways of which the signal detection information exceeds the signal intensity threshold value based on the signal comparison result, and determining the Internet of things gateways for switching the Internet of things terminals based on the gateway corresponding relation.
Specifically, the internet of things gateways (excluding the internet of things gateways to which the internet of things terminals are currently connected) with signal detection information exceeding the signal intensity threshold are screened out according to the signal comparison results corresponding to each internet of things terminal, and the internet of things gateways are internet of things gateways for stable access of the internet of things gateways.
Further, in the terminal gateway record table, for each internet of things terminal, the corresponding relationship between the internet of things terminal and the screened internet of things gateway is deleted, and the internet of things gateway still recorded in the terminal gateway record table at this time is the internet of things gateway which can be stably accessed by the internet of things gateway. It can be understood that when the signal strength information corresponding to other internet of things gateways detected by the internet of things terminal does not reach the signal strength threshold value, the internet of things gateways corresponding to the terminal gateway record table are deleted, that is, there is no internet of things gateway for the internet of things terminal to switch.
S205: screening out all the internet of things gateways for switching, wherein the internet of things gateways are located in the same internet of things network, and determining corresponding receivable load capacity based on the screened out all the current information load capacity corresponding to the internet of things gateways.
Specifically, the internet of things gateways where all the internet of things gateways recorded in the terminal gateway record table are located are determined, the internet of things gateways located in the same internet of things network as the internet of things gateways with the current information load exceeding the load threshold are screened out, and the corresponding relations between the rest of the internet of things gateways and the corresponding internet of things terminals are further deleted in the terminal gateway record table.
Further, the internet of things gateways screened out from the current terminal gateway record table are determined, and load detection requests are sent to the screened internet of things gateways based on the internet network, so that the internet of things gateways return corresponding receivable load amounts based on the current gateway load amounts.
S206: and determining the Internet of things terminal corresponding to the screened Internet of things gateway, and acquiring the information transmission quantity of the corresponding Internet of things terminal.
Specifically, after the internet of things gateways are screened in the terminal gateway record table, the internet of things terminals corresponding to the internet of things gateways are determined, and the information transmission quantity of the internet of things terminals is obtained. The information transmission quantity can be determined according to the average information quantity uploaded to the internet of things gateway by the internet of things terminal in a set time period.
S207: and determining the Internet of things terminal and the corresponding Internet of things gateway which need to be switched according to the receivable load amount corresponding to each Internet of things gateway and the corresponding information transmission amount of the Internet of things terminal.
Specifically, the internet of things gateways are subjected to bubbling sequencing according to the size of receivable load, the internet of things terminals which are not distributed with the internet of things gateways and correspond to each internet of things gateway are sequentially determined, when the receivable load is larger than the information transmission quantity according to the receivable load and the information transmission quantity of the corresponding internet of things terminals, the internet of things gateways are distributed to the corresponding internet of things terminals, the receivable load of the internet of things gateways is updated (the original receivable load is subtracted from the corresponding information transmission quantity to serve as a new receivable load), and the internet of things gateways used for switching are distributed to the internet of things terminals according to the mode.
In one possible embodiment, in the process of allocating the internet of things gateway for switching to the internet of things terminal, information transmission amount corresponding to the internet of things terminal allocated to the switchable internet of things gateway is accumulated, and when the accumulated amount obtained by subtracting the information transmission amount from the current information load amount is smaller than a load amount threshold value, the internet of things gateway for switching to the remaining internet of things terminal can be stopped being allocated.
S208: and informing the Internet of things terminal to switch to the corresponding Internet of things gateway.
S209: determining downlink data which needs to be sent to the internet of things terminal, and sending the downlink data to the internet of things gateway which needs to be switched by the internet of things terminal, so that the internet of things gateway sends the downlink data to the internet of things terminal after accessing the internet of things terminal.
Specifically, when downlink data which needs to be sent to the internet of things terminal which is disconnected for switching the gateway is generated or received, the downlink data is sent to the internet of things terminal which needs to be switched because the original internet of things gateway is disconnected from the internet of things terminal and the internet of things terminal does not have access to a new internet of things gateway. The gateway of the Internet of things receives downlink data, determines the terminal of the Internet of things corresponding to the downlink data, and sends the corresponding downlink data to the terminal of the Internet of things after the terminal of the Internet of things is successfully accessed, so that the downlink data generated in the switching process of the gateway can be correctly transmitted to the corresponding terminal of the Internet of things.
S211: and determining whether the Internet of things terminal is successfully switched to the Internet of things gateway or not, if the switching of the Internet of things terminal to the Internet of things gateway fails, re-determining the Internet of things gateway switched by the Internet of things terminal, and sending the downlink data to the Internet of things gateway to be switched by the Internet of things terminal again.
Specifically, in a set time period, the internet of things gateway switched by the internet of things terminal is continuously inquired whether the internet of things terminal is successfully switched to the internet of things gateway, and whether the internet of things terminal is successfully switched to the gateway is determined according to a reply of the internet of things gateway. And if the gateway is successfully switched by the Internet of things terminal, the transmission of the downloaded data is completed, and if a reply indicating that the gateway is successfully switched by the Internet of things terminal is not received within a set time period, the gateway switching failure of the Internet of things terminal is considered.
Further, when it is determined that the switching gateway of the internet of things terminal fails and is reconnected to the original internet of things gateway, other internet of things gateways for switching are determined again according to receivable load amounts of other internet of things gateways in the same internet of things network and the information transmission amount of the internet of things terminal, the internet of things terminal is informed to switch to the newly determined internet of things gateway, and downlink data are sent to the internet of things gateway which needs to be switched by the internet of things terminal again.
The above-mentioned, collect through the current information load volume to each thing networking gateway, when the current information load volume of thing networking gateway exceeded the load volume threshold value of settlement, according to the signal strength information that each thing networking terminal of thing networking gateway current connection corresponds with other thing networking gateways that detect, confirm the thing networking gateway that can supply each thing networking terminal to switch, and confirm the receivable load volume of these thing networking gateways, confirm the thing networking terminal that needs to carry out the gateway switching and the thing networking gateway that corresponds according to the receivable load volume, and inform corresponding thing networking terminal and switch to the thing networking gateway that corresponds, distribute the thing networking equipment to the thing networking gateway that has data transmission residual power, promote the data transmission quality to the thing networking equipment. Meanwhile, in the process of switching the gateway of the Internet of things terminal, downlink data needing to be sent to the Internet of things terminal is stored firstly, the downlink data are sent to the Internet of things terminal needing to be switched, and the received downlink data are sent to the Internet of things terminal after the Internet of things terminal detects the access of the Internet of things terminal, so that the data can be correctly sent to the Internet of things terminal after the gateway is switched, the situation that the downlink data cannot be correctly sent in the process of switching the gateway of the Internet of things terminal is reduced, and the data transmission quality is improved.
