step 1: a master device and a plurality of slave devices are deployed, the slave devices are in networking communication with each other, and at least one slave device and the master device are in networking communication;
the master device and the slave device communicate through a wired network or a wireless network.
As shown in fig. 1, a networking manner of this embodiment is shown, where a master device performs networking with a slave device A1 and a slave device I, a slave device A1 performs networking with a slave device B1, a slave device D and a slave device J, a slave device C performs networking with the slave device B1 at the beginning, but performs networking with the slave device D after being disconnected, a slave device E and a slave device F each perform networking with the slave device B1, a slave device G and a slave device H each perform networking with the slave device F, and the slave device G is in a dropped state;
step 2: the master device generates a link state protocol and sends the link state protocol to all the slave devices in a transparent transmission mode;
when executing the step 2, the method specifically comprises the following steps:
step 2-1: the master device sends a link state protocol to a slave device A which is networked with the master device;
as shown in fig. 1, the master device sends a link state protocol to the slave device A1, and the link state protocol is sent to the slave device D and the slave device B1 by the slave device A1 in a transparent transmission manner;
step 2-2: slave device a judges its own networking state: if the number of other slave devices which are networked with the slave device A is 0, the slave device A considers itself to be a networking terminal device, and the step 2-3 is executed; if the number of other slave devices which are networked with the slave device A is not 0, the slave device A considers itself to be an upper-level device, and the steps 2-4 are executed;
step 2-3: the slave device A returns state return information to the master device and executes the steps 2-7;
in fig. 1, the slave device I is not a subordinate device, where the slave device I is the slave device a in step 2-3, after receiving the link state protocol, the slave device I is a network endpoint device because no other slave devices are networking with the slave device I, and the slave device I directly returns state return information to the master device, and sets the network endpoint device identifier as 1 in the state return information.
Step 2-4: the slave device A transmits a link state protocol to a slave device B which is networked with the slave device A;
setting the slave device B as the lower-level device of the slave device A, and setting the slave device B as the upper-level device and the slave device B as the lower-level device of the slave device B in the same way as other slave devices which are networked with the slave device B;
the slave device A1 and the slave device B1 are the device A and the device B in the step 2-4; since the slave device A1 also has the subordinate device B1, the subordinate device D, and the subordinate device J, the slave device A1 is not a networking endpoint device, and the device A1 still needs to continue to pass the link state protocol downward.
Step 2-5: after receiving the link state protocol, the slave device B judges its own networking state: if the number of other slave devices which are networked with the slave device B is 0, the slave device B considers itself to be a networking terminal device, and the steps 2-6 are executed; otherwise, the slave device B continues to transmit the link state protocol to the subordinate device which is networked with the slave device B, and the step 2-7 is executed;
step 2-6: generating a state return message from the equipment B, namely adding the networking number of the equipment B into the networking number of the networking terminal equipment, and setting the network terminal equipment identification of the networking terminal equipment, and clearing the number of the upper equipment, the networking number list of the upper equipment and the local return timestamp list of the upper equipment;

the slave device J is the device B in the step 2-6, and the slave device J is a networking terminal device.
Step 2-7: according to the method principles of the step 2-2 and the step 2-6, each lower-level device which receives the link state protocol returns state return information to the upper-level device;
each upper-level device receiving the return state return information adds own networking number in a network number list of the upper-level device in the return state return information, and adds local time in a local return timestamp list of the upper-level device;
the superior device finally transmits the status return information to the master device.
As shown in fig. 1, when executing steps 2-7, the slave device E and the slave device F are both lower devices of the slave device B1, and at this time, the slave device E is a network endpoint device, which generates status return information after receiving the link status protocol, where the network endpoint device identifier in the status return information is set to 1, the network endpoint device network number is the network number of the slave device E, and the slave device E returns status return information to the master device;
when state return information is returned, data transmission is required to be carried out through the slave equipment B1 and the slave equipment A1, when the slave equipment B1 and the slave equipment A1 carry out data transmission, the self networking number is added into a network number list of the upper-level equipment, and meanwhile, the self local time is added into a local return timestamp list of the upper-level equipment;
slave F is not a networking endpoint device and then slave F continues to pass the link state protocol down to slave H and slave G.
The principle of the slave H and the slave G is the same as that of the slave E when they return information in the return state.
Step 3: the slave device receives a link state protocol, and sends state return information to the master device through the upper device networking with the slave device in a transparent transmission mode, and when the upper device transmits the state return information in a transparent mode, the slave device adds own networking number and local return time into the state return information;
the state return information comprises a networking terminal equipment identifier, networking terminal equipment networking numbers, the number of the upper-level equipment, a list of the networking numbers of the upper-level equipment and a list of local return time stamps of the upper-level equipment;
the upper-level equipment pushes the disconnection information of the slave equipment which performs networking with the upper-level equipment to the master equipment;
as shown in fig. 1, assuming that the slave device G is disconnected, after the slave device F transmits the link state protocol to the slave device G, the slave device G always has no reply state return information, and for the slave device F, the slave device F fails to receive the state return information of the slave device G within a preset time, and at this time, the slave device F considers that the slave device G is disconnected, and the slave device F actively pushes the disconnection state information of the slave device G to the master device.
Step 4: and the master equipment updates the group network state according to the disconnection state information and the state return information.
When executing the step 4, the method specifically comprises the following steps:
step 4-1: when the main equipment receives the line-down state information, extracting the networking number of the subordinate equipment in the line-down state information;
step 4-2: traversing all the state return information by the main equipment, and comparing and checking the networking number of the networking terminal equipment in the state return information with the networking number of the subordinate equipment: if the device is the repeated number, the device which records the repeated number is the slave device C, and then the step 4-3 is executed; if the number is not repeated, executing the step 4-5;
step 4-3: at this time, the network state is changed, and the master device updates the network state according to the state return information returned by the slave device C and issues a new network state list;
step 4-4: all slave devices update their networking states according to the new networking state list, and execute steps 4-6;
step 4-5: at this time, it indicates that the mesh state is not changed;
step 4-6: ending
When the steps 2-4 and 2-5 are executed, if the slave device A fails to receive state return information returned by the slave device B within preset time after the link state protocol is transmitted from the slave device A to the slave device B, the slave device A considers that the slave device B is not on line, and the slave device A pushes the state return information of the slave device B to the master device;
similarly, when the upper-level device does not receive the state return information of the lower-level device in the set time, the upper-level device pushes the state drop information of the lower-level device to the main device;
the drop state information comprises the networking number of the upper-level equipment, the networking number of the lower-level equipment and the drop identification code.
Taking the slave device F and the slave device G as examples, the slave device G is a lower-level device of the slave device F, the slave device G is disconnected, the networking number of an upper-level device is the networking number of the slave device F, the networking number of the lower-level device is the networking number of the slave device G, the disconnection identification code is set to be 1, and the disconnection state information is actively pushed to the master device by the slave device F.
As shown in fig. 1, this embodiment simulates a scenario of a networking change, where the first upper device of the slave device C is the slave device B1, but due to network delay and other reasons, the slave device C disconnects the link with the slave device B1, and switches to the link with the slave device D, at this time, the slave device B1 actively sends the drop state information of the slave device C to the master device, and the slave device C replies the state reply information through transmission to the master device, at this time, both the state reply information and the drop state information received by the master device include the networking number of the slave device C, the state reply information is included in the networking number of the networking endpoint device, the drop state information is included in the networking number of the lower device, at this time, the master device finds the networking number of the slave device C through comparison and re-searches, and further learns the networking change, and the master device updates the networking change list, and issues a new networking change list to the slave device, and downloads itself and further details its own networking change list.
Because the state return information of the invention contains the local time information of each device when transmitting data, the master device can obtain the data transmission delay between each device by calculating the time difference between the local time, thereby obtaining the data transmission delay between each slave device and the master device.
The invention adopts the transmission protocol of the master device, the protocol transmitted by the master device has simple structure and good compatibility to all slave devices, the master device replies the transmission protocol to the master device through the device at the networking terminal point, so that the master device can master the first hand data of the terminal point device, and can calculate the data transmission delay of the devices of each node at the same time, finally obtain the data delay between each slave device and the master device, and realize the function of the master device for monitoring the data transmission state and the data transmission speed of the whole networking.
