Example 1
As shown in fig. 1, the method is a schematic flow chart of a seamless implementation method of an LED splicing wall system according to an embodiment of the present invention, and the method includes the steps of:
s101, grouping a plurality of LED output node transmitters into a main group and a standby group, wherein the LED output node transmitters in the main group and the standby group are in one-to-one mutual backup;
the method can realize seamless redundancy switching of the whole LED splicing wall system under the condition that a main redundant LED output node transmitter fails when the distribution quantity of super-large-scale network data is large, wherein in step S101, a pure software control mode is adopted to control the LED output node transmitters, the method comprises the steps of adjusting the brightness and the color temperature of the LED output node transmitters, controlling the output of the LED output node transmitters to be turned on or turned off, in the method, the pure software control mode is adopted to carry out main and standby grouping management on all the LED output node transmitters, the LED output node transmitters in the main grouping and the LED output node transmitters in the standby grouping are divided into the main grouping and the standby grouping, the LED output node transmitters in the main grouping and the LED output node transmitters in the standby grouping are in one-to-one corresponding backup relation, the working-states of the main grouping and the standby grouping are opposite, for example, when 60 LED output node transmitters are in the system, the method comprises the steps that 60 LED output node transmitters are grouped into a main group and a standby group, the main group and the standby group are respectively provided with 30 LED output node transmitters, the LED output node transmitters in the main group and the standby group are in one-to-one mutual backup, when the working state of the main group is in an output starting state, the working state of the standby group is in an output closing state, and vice versa.
S102, each LED output node transmitter in the main group or the standby group judges whether heartbeat data of a receiving node is abnormal or not;
in step S102, it may be specifically determined whether an abnormality occurs by determining whether one or more LED output node transmitters in the main packet or the standby packet do not receive the node heartbeat data within a preset time. Specifically, when one LED output node transmitter does not receive node heartbeat data or node heartbeat data is lost, it is determined that the node heartbeat data is abnormal, and at this time, the output of the main packet (or the standby packet) where the LED output node transmitter that receives the node heartbeat data is abnormal is controlled to be turned off, and the output of the standby packet (or the main packet) where the LED output node transmitter that is backed up with the abnormal LED output node transmitter is correspondingly switched to be turned on; when the plurality of LED output node transmitters do not receive node heartbeat data, the output of the main group (or the standby group) where the LED output node transmitter which is judged to be abnormal firstly is correspondingly controlled to be closed, and the output of the standby group (or the main group) where the LED output node transmitter which is backed up mutually is correspondingly switched to be started.
In addition, in this embodiment, the following method is specifically adopted for each LED output node transmitter in the main packet or the backup packet to receive node heartbeat data:
firstly, acquiring node response time of each LED output node transmitter in the main packet or the standby packet; specifically, the node response time is calculated and obtained by assuming that node heartbeat data is correspondingly sent at time T0, and an LED output node transmitter receives the node heartbeat data at time T1, so that the node response time T of the LED output node transmitter is T1-T0, and thus the calculation process obtains the node response times T1 and T2 … … tn of each LED output node transmitter in a main packet or a standby packet, and establishes a node response time information data table with a data table structure of structtieinfo, where the first data in the information data table is the node response time of the LED output node transmitter with the longest response time, and if the node response time of a newly inserted LED output node transmitter is not the longest time-consuming node, the node response time is compared with the node response times of the remaining LED output node transmitters, and the insertion position is: when the node is smaller than the Nth node and larger than the (N + 1) th node, the node is inserted into the (N + 1) th position, and the data after the (N + 1) th position are sequentially moved backwards, so that the node response time of the LED output node transmitters in the data table is arranged from large to small;
secondly, each LED output node transmitter in the main packet or the standby packet correspondingly controls the frequency of receiving the node heartbeat data to be reduced or increased according to the corresponding node response time so as to balance network load. Specifically, the process of receiving heartbeat data by each LED output node transmitter is that the interval time of receiving the heartbeat data by the LED output node transmitter is set as T, the number of times N of receiving the heartbeat data by the same time transmitter of each transmitter is calculated to be 1/T1000, the number of transmissions is 1000ms, the larger T, the smaller T, the larger T, therefore, the network load balance can be adjusted to avoid the network from being blocked, the sender node which responds quickly sends more heartbeat packets, the heartbeat message of the splicing software control system can be responded quickly, the node which responds slowly sends less heartbeat packets at the same time point, the network blocking caused by the heartbeat packets which are sent to the node which cannot respond in time is avoided, the nodes with slow response send few heartbeats, so that the network load balance is completely achieved, and network blockage caused by slow response of the nodes in a super-large system is avoided.
In the embodiment, in the LED spliced wall system with large data distribution capacity of a super-large scale network, different heartbeat data receiving times of different LED output node transmitters are correspondingly received according to the difference of node response time of each LED output node transmitter in a main group or a standby group, so that the frequency of receiving heartbeat data by the different LED output node transmitters is adjusted, the network load is balanced when the data distribution capacity of the network is very large and a large number of real-time heartbeat packets are required to be distributed ceaselessly, and the condition that redundancy switching cannot be realized due to the fact that part of nodes cannot receive notification messages is avoided.
S103, if the node heartbeat data is judged to be abnormal, the output of the main packet or the standby packet where the abnormal LED output node transmitter is located is controlled to be closed in real time, and the standby packet or the main packet where the LED output node transmitter corresponding to the abnormal LED output node transmitter is located is switched to be started, so that the main packet and the standby packet are synchronously, seamlessly and redundantly switched.
In step S103, the output of the main packet or the standby packet is controlled to be closed in real time, and the output of the switching standby packet or the main packet is started, so that the main packet and the standby packet perform synchronous seamless redundancy switching, which specifically includes:
s1031, obtaining the maximum node response time of the main packet or the standby packet;
in step S1031, the specific method of obtaining the maximum node response time of the main packet or the standby packet is to first obtain the node response time of each LED output node transmitter in the main packet or the standby packet; secondly, comparing the response time of each node in the main group or the standby group to obtain the maximum value which is the maximum node response time;
s1032, if the node heartbeat data is judged to be abnormal, the output of the main packet or the standby packet where the abnormal LED output node transmitter is located is controlled to be closed in real time within the maximum node response time, and the output of the standby packet or the main packet where the LED output node transmitter corresponding to the abnormal LED output node transmitter is located is switched to be started, so that the main packet and the standby packet are synchronously, seamlessly and redundantly switched.
In step S1032, the node response times of the LED output node transmitters in the primary or backup grouping are all different, and the LED output node transmitters are controlled to output and turn off at the same maximum node response time, which specifically includes:
s10321, calculating each time difference corresponding to the maximum node response time and the node response time of each LED output node transmitter, where each time difference is a delay response time corresponding to each LED output node transmitter;
s10322, if the node heartbeat data is judged to be abnormal, each LED output node transmitter in a main grouping or a standby grouping where the abnormal LED output node transmitter is located is controlled to be delayed to close output at the corresponding delay response time in real time, and the standby grouping or the main grouping where the LED output node transmitter corresponding to the abnormal LED output node transmitter is located is switched to be started, so that the main grouping and the standby grouping are synchronously, seamlessly and redundantly switched.
As can be seen from the above, in step S103 of this embodiment, a specific implementation process for controlling in real time that the output of the main packet or the backup packet where the LED output node transmitter with the abnormality is located is turned off, and switching the output of the backup packet or the main packet where the LED output node transmitter corresponding to the LED output node transmitter with the abnormality is located is turned on, includes obtaining the node response time and the maximum node response time of each LED output node transmitter in the main packet or the backup packet according to the node response time information data table having the structttimeinfo structure, calculating the delay response time according to the difference between the node response time and the maximum node response time of each LED output node transmitter, and controlling all the LED output node transmitters in the main packet or the backup packet to turn off the output in real time at the maximum node response time when all the LED output node transmitters start to output work in the same node response, the method is characterized in that the corresponding delay response time of each LED output node transmitter in the main group or the standby group is delayed in the node response time of the LED output node transmitter, so that the closing time of all the LED output node transmitters is the maximum node response time, seamless switching signals of all the LED output node transmitters are realized, and visual impact effect cannot be caused to field operators.
