Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
In order to reach object of the present invention, as Figure 1-4, in the some of them embodiment of image intelligent synchronization method that the present invention is based on optical fiber distributed type display system,
Based on the image intelligent synchronization method of optical fiber distributed type display system, for under optical fiber distributed type display system (as shown in Figure 1), synchronous each image node collects the data collected, the node sending synchronizing signal can be arbitrary node, Intelligent Matching and intelligence substitute can be realized between each node, ensure that synchronizing signal uninterruptedly sends.Synchronizing signal is embedded with synchronizing information, and synchronizing information comprises the priority of the active synchronization node sending synchronizing signal.
As shown in Figure 2, all there are three kinds of operating states in each node, each node can make state transition according to whether existing in system synchronizing information embedded in synchronizing signal and synchronizing signal, switch between three kinds of operating states, and final Intelligent Matching selects a node as active synchronization node, its three kinds of operating states are specially:
Passive and synchronous state, node is active synchronization node in this case, is responsible for receiving synchronizing signal;
Intelligence substitute state, node can send the request of intelligence substitute in this case, and the request of intelligence substitute is embedded with the priority of this node;
Active synchronization state, node is active synchronization node in this case, is responsible for sending synchronizing signal, reception resolve the intelligence substitute request that other nodes send.
In order to ensure the stable of synchronizing signal, in same displaying time, in same system, have and only have a node to be active synchronization node, remaining node is passive and synchronous node.
As shown in Figure 3, the present invention is based on the image intelligent synchronization method of optical fiber distributed type display system, specifically comprise the following steps:
(1) priority of each node is determined;
(2) judge whether there is synchronizing signal in system; If there is arbitrary node not receive synchronizing signal, then synchronizing signal is lost, and enters step (3); If there is synchronizing signal in system, then enter step (4);
(3) when the synchronizing signal in system goes out active, namely damaging or removing appears in active synchronization node, then each node can be substituted from passive and synchronous state transition to intelligence state, and send the request of intelligence substitute, system is according to the request of intelligence substitute, Intelligent Matching goes out the highest node of priority, by this node from intelligence substitute state transition be active synchronization state, namely this node is active synchronization node, be responsible for sending synchronizing signal, all the other nodes are passive and synchronous state from intelligence substitute state transition;
(4) when there is synchronizing signal in system, each passive and synchronous node receives synchronizing signal and analyzes synchronizing information embedded in synchronizing signal, the priority of the priority of this passive and synchronous node and active synchronization node is contrasted,
If the priority of passive and synchronous node is higher than the priority of active synchronization node, then passive and synchronous node sends the request of intelligence substitute to active synchronization node, and the request of intelligence substitute comprises the priority of passive and synchronous node, carries out intelligence and switches;
If the priority of passive and synchronous node is lower than the priority of active synchronization node, then passive and synchronous node normally receives synchronizing signal.
As mentioned above, when there is no synchronizing signal in system, each node can be substituted from passive and synchronous state transition to intelligence state, and send the request of intelligence substitute, do not have active synchronization node in system, system is directly according to the request of intelligence substitute, and Intelligent Matching goes out the highest node of priority, by this node from intelligence substitute state transition be active synchronization state, all the other nodes from intelligence substitute state transition be passive and synchronous state.And when there being synchronizing signal in system, and the priority of passive and synchronous node is higher than the priority of active synchronization node, then passive and synchronous node sends the request of intelligence substitute directly to active synchronization node.Therefore in the above-mentioned two kinds of situations whether existed in synchronizing signal, the receiving target of intelligence substitute request is different.
As shown in Figure 4, in above-mentioned steps (4), the detailed process that intelligence switches is as follows:
Active synchronization node receives intelligence substitute and asks and resolve the request of intelligence substitute, the priority of the priority of passive and synchronous node and active synchronization node is contrasted,
If the priority of passive and synchronous node is higher than the priority of active synchronization node, then by active synchronization nodal regression to passive and synchronous state, passive and synchronous node is jumped to active synchronization state;
If the priority of passive and synchronous node is lower than the priority of active synchronization node, then active synchronization node normally sends synchronizing signal.
Step (4) can be unified the node in whole system, if there is priority newly to access higher than the node of existing active synchronization node, then the state of active synchronization node changes, ensure that the synchronizing signal of whole system is stablized, ensure that the node of limit priority sends synchronizing signal, synchronizing signal sends accurately, there will not be mixed and disorderly and is interrupted.
Intelligence switches can ensure that the switching of active synchronization node and passive and synchronous node is accurate.
Image intelligent synchronization method based on optical fiber distributed type display system has following characteristics:
Without the need to artificially specifying synchronization node, freely there is synchronizing signal by each node, then arbitrating with self coupling according to the priority of sending node embedded in the synchronizing signal received, determining the selection of final synchronization node.Even if current synchronization node breaks down, synchronizing signal can not occur, other nodes can be made rapidly substitute and switch and mate the synchronization node made new advances, and display system can not be paralysed because of the fault of a certain synchronization node.Can effectively ensure the uninterrupted of synchronizing signal, ensure the data that each image node synchronous collects, occur that phenomenon torn by the asynchronous image caused when preventing image from showing on display body of wall, the generation node of its synchronizing signal can be arbitrary node.
Novel preferred implementation, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
