As shown in fig. 2, a network ring connector composed of a master single chip and two PHY chips in hardware implements a loop redundancy function, the ring connector is connected between a conference host and a conference unit, one end of the network ring connector is connected to the host, and the other end of the network ring connector is connected to a final conference unit, one PHY chip is used for detecting whether a loop is formed, and the other PHY chip is used for communicating with other loops, and the PHY chip used for detecting whether a loop is formed is initialized to a VLAN virtual local area network mode, and by setting VLAN tag and VLAN id, an uplink port can select to send a message from a designated VLAN id port to detect whether the loop is disconnected.
Based on the above system structure, the following describes the implementation principle of the embodiment of the present application: specifically, the main thread can send a data detection packet with a VLANTAG at a fixed time of 1ms and start counting, if a receiving sub-thread does not receive the detection packet after 3ms overtime, the receiving sub-thread can judge that a loop of the receiving sub-thread is in a disconnected state, at the moment, the receiving sub-thread is informed to switch the mode of the chip from a VLAN mode to an adaptive hundred mega mode, a chip queue cache is emptied and no message is sent in the switching process, the judgment influence of the cached message on the loop is avoided, the switching is recovered after the switching is completed, 5ms of switching time is needed in the switching process, and at the moment, the PHY chip supplies a network to a conference unit at the disconnected end after the switching is switched to the adaptive hundred mega mode. And at the moment, the detection message is sent in a self-adaptive mode for 1ms, and when the loop is closed, the loop is immediately switched to a VLAN mode to avoid network storm. The entire detected mode switch complete control ensures that no tone breaks occur in the audio transmission within 10ms. The PHY chip for communication with other loops is set to be in a self-adaptive hundred-megabyte mode to send broadcast messages to inform the state of other loops, and the condition judgment of the PHY chip is prevented from being influenced by the opening and closing of other loops.

Preferably, the time taken for the notification sub-thread to switch to the VLAN local area network mode and empty the network packet queue is less than or equal to 5ms.
In some embodiments, the method for multi-loop detection and network replenishment of a conference system further comprises:
when the data UDP unicast message is monitored and other received loops are in a disconnected state, filtering for 3ms and detecting whether the message can be continuously received;
if yes, executing the step of switching the notification sub-thread into the VLAN local area network mode;
if not, returning to the step of monitoring the data UDP unicast message sent by the main thread in the self-adaptive hundred-million full duplex mode by the control sub-thread.
Referring to fig. 3, fig. 3 provides a total flow of the implementation process of the multi-loop detection and network replenishment method of the conference system, and the method of the present application will be described with reference to fig. 3:
the method comprises the following steps: the method comprises the steps of electrifying and initializing environment variables, creating threads and configuring a PHY chip, configuring a loop detection PHY chip into a VLAN local area network mode, and configuring a loop communication PHY chip into a self-adaptive hundred-megabyte full-duplex mode.
Step two: the timer is used for informing the main thread that the destination MAC address of the data detection message with the VLANTAG in the VLAN mode is self-owned by the main thread after 1ms, and the timeout counting of 3ms is started.
Step three: and detecting that the PHY chip message sub-thread is in a monitoring state by the receiving loop, if a message with a VLANTAG (virtual local area network) sent by the main thread is monitored within 3ms of the VLAN local area network mode, informing the main thread of detecting the position of the mark 0 in the overtime state, and otherwise, going to the step five. And if the specific data UDP unicast message sent by the main thread is monitored in the self-adaptive hundred-megabyte full-duplex mode, informing the main thread to step seven.
Step four: and the message sub-thread of the PHY chip for loop connection communication is in a monitoring state, and if the loop state broadcasted by other loops is received, the states of other loops are recorded, and the number of disconnected loops is recorded.
Step five: at the moment, the main thread judges that the overtime counting flag bit exceeds 3ms and the loop detection PHY chip is in a VLAN mode, the loop can be judged to be disconnected, at the moment, the sub-thread is informed to convert the loop detection PHY chip from the VLAN mode to a self-adaptive hundred-million full duplex mode, seamless network supply is provided for the disconnected conference unit, the whole process is completed within 10ms, the audio of the disconnected conference unit is quickly restored to a normal state, and therefore the effect that the sound is not interrupted by continuing network packet audio transmission is achieved. And broadcasts its own loop status to the other loops.
Step six: after the mode is switched to the self-adaptive hundred-megabyte full duplex mode, the main thread switches to send a specific data UDP unicast message, and the destination MAC address is the MAC address of the main thread.
Step seven: the main thread is in a self-adaptive hundred-million full duplex mode and receives a UDP unicast message sent out in the self-adaptive hundred-million full duplex mode, whether other loops are in a disconnected state or not is judged, if the loops are not in the disconnected state, the converter sub-thread is immediately informed to be switched to a VLAN mode, a network packet queue is emptied and no message is sent in the switching process, and the condition judgment error caused by message accumulation and network storm possibly caused are avoided. The whole process is controlled within 5ms. If there is an open loop, it needs to judge whether the message arrives from the open to close moment of other loops and is not from the loop itself, at this time, it needs to count and judge whether the serial number of the message is greater than 5 (which is equivalent to continuously receiving the message after 5ms, if it is the open and close moment of other loops, it is the packet in 5ms will pass through the loop and the VLAN mode message will not pass through the loop after closing), and filter the influence of other loops from open to close moment. The whole process is within 10ms. The loop status of itself is broadcast to other loops. And then the network packet audio transmission is continued to achieve the effect of uninterrupted sound and the step two is returned again.
To sum up, the conference system multi-loop detection and network replenishment method provided by the embodiment of the application can ensure that a conference is normally carried out, and after a communication link is disconnected due to the conditions of network cable looseness and the like, a normal network is detected and provided within 3ms so that network communication is normal, and the normal running of the conference is ensured. When the link has a problem, the normal operation can be quickly recovered, so that the audio can be seamlessly connected, and the continuity of audio output is guaranteed. Meanwhile, the method can ensure that the plurality of loops can keep communication, know the states of each other and avoid the phenomenon that the states of the plurality of loops influence each other and network storm occurs to cause network paralysis.
