It can be understood that the scheme specifically uses the communication of the data link layer to enumerate the cascade devices, and when enumerating a device, makes two network cards of the device work in a hybrid mode, so that each network card can receive all data packets (including data packets whose MAC addresses are not native) on the network, and binds the network ports of the two network cards as ports of the virtual bridge.
The bridge is a connection device of the data link layer, which transfers information between the data link layers of two local area networks, and functions as a bridge, transparent to the end node user, and the end node does not know the existence of the bridge when its message passes through the bridge. Thus, the cascade devices can communicate seamlessly.
When the verification process occurs that the equipment is in cascade connection, when the equipment is in cascade connection through the network cable, the front-stage equipment detects that the state of the network port connected with the access equipment changes, a frame of broadcast frame is sent on the data link layer, after the access equipment receives the frame of broadcast frame, the source MAC address is resolved, a frame of response is sent to the front-stage equipment, and therefore the two-stage equipment knows the MAC addresses of the opposite side mutually before the two-stage equipment, and stable communication can be established on the data link layer.
After that, the front-stage device sends an IP address allocation instruction, the access device receives the instruction and then establishes a network bridge through the newly-built network bridge, and sets an IP address for the network bridge, so that the front-stage device and the rear-stage device can communicate through the IP address by using a network communication protocol.
For the equipment of the network cable serial cascade, after the scheme is adopted, the equipment can be dynamically and real-time connected into the existing cascade system or disconnected from the existing cascade system, the deployment is very simple and convenient, the additional equipment cost is avoided, the stability and the reliability of transmission can be ensured to the greatest extent, the ultra-low time delay is provided, and the data synchronization between the equipment is ensured.
The scheme can realize the scene that the equipment at two ends of the cascade carries out mutual PING, and has the following advantages:
1. the scheme enumerates all devices connected in series, sets a network bridge for all the devices and distributes correct IP addresses for the devices;
2. after the distribution is completed, the rapid and stable network communication can be carried out between any two pieces of equipment;
3. the scheme can provide rapid, stable and safe guarantee for serial equipment cascade communication.

a second establishing unit 2, configured to establish a data link between the second devices 20 at each preceding and succeeding stage in the first data link.
Correspondingly, the invention also discloses a computer readable storage medium for storing a computer program, and the program realizes the serial cascade establishment method when being executed by a processor.
It should be noted that all the second devices 20 in the present embodiment may be fully connected to the first data link, or may be partially connected to the first data link, so as to achieve flexible increase and decrease of the second devices 20, for example, when the present embodiment is applied to a conference room, some areas of the conference room are sitting listeners, and the rest areas are not sitting listeners, at this time, only the second devices 20 corresponding to the area of sitting listeners may be connected to the first data link, so as to meet the use requirement.

7. The serial concatenation establishment method of claim 6, wherein: the step S1 specifically includes:
s11, the first equipment detects the access state of the subsequent stage;
s12, when the first equipment detects that the second equipment is accessed to the subsequent stage, the first equipment sends the MAC address and the IP address to the second equipment positioned at the subsequent stage;
s13, a second device positioned at the rear stage of the first device generates an independent IP address and a link number according to the MAC address of the second device, the MAC address and the IP address of the first device, and the link number of the second device is n+1;
s14, the first device and the second device at the back stage of the first device together form a data link between the first device and the second device at the back stage of the first device according to the MAC address and the IP address of the first device and the MAC address and the IP address of the second device at the back stage of the first device.
8. The serial concatenation establishment method of claim 7, wherein: the step S2 specifically includes:
s21, for the ith second device in the first data link, detecting the access state of the subsequent stage of the ith second device in the first data link;
s22, when the ith second device in the first data link detects that the second device is accessed to the subsequent stage, the ith second device in the first data link sends the MAC address and the IP address of the ith second device to the second device in the subsequent stage;
s23, a second device at the rear stage of the ith second device in the first data link generates an independent IP address and a link number according to the MAC address of the second device and the MAC address and the IP address of the ith second device in the first data link;
s24, forming a data link between the ith second device in the first data link and the second device at the rear stage of the ith second device in the first data link together according to the MAC address and the IP address of the ith second device in the first data link and the MAC address and the IP address of the second device at the rear stage of the ith second device in the first data link;
and S25, repeating the steps S21 to S24 until a data link is established between the second devices at each front and rear stage in the first data link.
9. A serial concatenation establishing device applied to the serial concatenation structure according to any one of claims 1 to 3, wherein the serial concatenation establishing device includes:
a first establishing unit, configured to establish a data link between a first device and a second device located at a later stage of the first device;
and the second establishing unit is used for establishing a data link between the second devices at each front and back stage in the first data link.
10. A computer-readable storage medium storing a computer program, characterized by: the program, when executed by a processor, implements the serial concatenation establishing method of any one of claims 6 to 8.
