The gateway sends data information to the first relay device before the first feedback message of the first relay that is not received by the gateway in the first time period, where the first feedback message is the gateway to the first relay. After transmitting the data information, the first repeater needs to send a feedback message to the gateway indicating that the information is received. If the feedback message fed back by the first repeater is not received within a certain period of time after the gateway sends the data information, the situation may be that the first repeater is damaged (the uplink fault of the first repeater or the first If the downlink of the repeater is abnormal, or the uplink and downlink of the first repeater are abnormal, etc., the gateway considers that the repeater is faulty for subsequent processing.

The starting point of the first time period is the time when the gateway sends the data information to the first repeater.

The duration of the first time period may be equal to, for example, 3s, 5s, 8s, 10s, 11s or the like. value. Preferably, the duration of the first time period is 8 s.

Wherein, if the gateway does not receive the first feedback message of the first relay in the first time period, the gateway is connected with X repeaters, and each of the repeaters is connected with X Internet of Things terminals. The connection also generates a link connection record including a connection relationship between the gateway and the repeater, a connection relationship between the repeater and the Internet of Things terminal, and the link connection record includes the current data forwarding rate of each of the above repeaters.

The link connection record is updated in real time.

In an embodiment, the gateway determines, according to the preset link exception processing rule, that the second relay is implemented by: the gateway acquiring the number of the Internet of Things terminals carried by the Y repeaters. The Y repeaters are repeaters of the X repeaters except the first repeater; the gateway will carry at least one relay of the number of IoT terminals less than or equal to a preset number The device acts as a second repeater.

Specifically, the specific manner in which the gateway acquires the number of the Internet of Things terminals carried by the Y repeaters is obtained by traversing the foregoing link relationship record.

Specifically, the specific manner in which the foregoing gateway obtains the data forwarding rate of the Y repeaters is obtained by querying the foregoing link relationship record.

In an embodiment, the preset data forwarding rate may be equal to, for example, 32 Mbps, 64 Mbps, 128 Mbps, 256 Mbps, 512 Mbps, 1024 Mbps, or other values. Preferably, the preset data forwarding rate is 256 Mbps.

It should be noted that the gateway at least has a data forwarding rate greater than or equal to a preset data forwarding rate. A repeater is used as the second repeater. The second repeater may be one or multiple. The present invention is not limited. In addition, when there is only one second relay, the second The relay may be the repeater with the highest forwarding rate. Of course, it may not be the repeater with the highest forwarding rate. The present invention is not limited. In addition, when there are one for the second repeater, where I is less than or equal to The number of repeaters whose data forwarding rate is greater than or equal to the preset data forwarding rate. The second repeater may use any one of the repeaters whose data forwarding rate is greater than or equal to the preset data forwarding rate, or may be data. The I repeater having a large forwarding rate is not limited in the present invention.

Further, when the K is less than a preset threshold, the number of the repeaters T is 1; when the K is greater than or equal to the preset threshold, the number of the repeaters T is greater than 1. Integer.

For example, if the preset threshold is 15, and K=10, the gateway migrates all 10 IoT terminals to one repeater T. It is also assumed that when K=21, the gateway migrates 21 Internet of Things terminals to at least two repeaters T, for example, the gateway selects the least number of the number of IoT terminals carried by the M second repeaters. Repeater or three repeaters with the highest data forwarding rate; the above-mentioned gateway evenly distributes the 21 Internet of Things terminals to the above three repeaters, that is, each of the above three repeaters migrates seven objects Networked terminal.

Further, the gateway migrates the remaining S ₂ Internet of Things terminals to at least one of the M-1 repeaters according to the number of the Internet of Things terminals carried in the M-1 repeaters. Specific implementations in the relay are:

or,

For example, assume that the number of the above NK Internet of Things terminals is 23, and the number of repeaters other than the repeater T of the M second repeaters is seven, according to the formula: (NK)/ (M-1)=S ₁ . . . S ₂ shows that S ₁ is 3 and S ₂ is 2. The gateway migrates the above seven repeaters to three IoT terminals respectively; the gateway re-traverses or queries the link connection record to obtain the minimum number of IOT terminals or the maximum data forwarding rate among the seven repeaters. The repeater; the gateway migrates the two Internet of Things terminals to the two repeaters.

After the link between the gateway and the first repeater returns to normal, the IoT terminals that are migrated from the first repeater to the second repeater are all migrated to the first repeater.

In the embodiment of the present invention, if the gateway does not receive the first feedback message of the first repeater in the first time period, the gateway acquires the second repeater according to the preset link exception processing rule; the gateway Will The IoT terminal carried by the first repeater migrates to the second repeater. It can be seen that when the communication between the gateway and the first repeater is abnormal, the IoT terminal carried by the first repeater is migrated to the second repeater to ensure that the first repeater carries the The IoT terminal can work normally, which solves the problem of maintaining normal data exchange between objects when the data exchange link fails.
