In the following description, the embodiment first for the signal switching method of combination of the present invention is described, then is described each embodiment of the signal switching system of combination of the present invention.
Shown in Figure 1, be the figure of the signal switching method embodiment of combination of the present invention.As shown in Figure 1, the signal switching method of the combination in the present embodiment comprises the steps:
Step S101: obtain at least one signal source as backup signal resource, wherein, described backup signal resource is the signal source except the display source signal of combination, and described display source signal is the signal source of the signal of current display on described combination;
At least one signal source can be obtained as backup signal resource from the signal source that user selects in advance, or whole signal sources user selected (can be also can for multiple) are as backup signal resource, now, the signal of the signal source in backup signal resource does not show on combination;
Step S102: state-detection is carried out to described backup signal resource and described display source signal;
State-detection can be carried out one by one respectively to the signal source in backup signal resource and the signal source in display source signal, consider that the former exception of signal mainly comprises two kinds of situations, a kind of situation is that the signal network in combination processor and front interrupts, and does not receive code stream information completely; Although it is normal that another situation is network, but due to camera picture be blocked or night camera head position do not throw light on cause very dark, show on combination although energy connecting signal source is still nonsensical in this case, equally also think abnormal signal, corresponding above two kinds of situations, also have two kinds of corresponding state-detection modes;
Mode one: the bit stream data that can detect described backup signal resource and described display source signal, do not receive the bit stream data of the arbitrary signal generator in described backup signal resource or described display source signal if detect, then determine that corresponding signal source occurs abnormal;
Particularly, periodically (such as can detect once every 10 seconds) and the bit stream data of described backup signal resource and described display source signal is detected, whether any detection once can send bit stream data to the signal source in backup signal resource and the signal source in display source signal is respectively detected, the bit stream data of the arbitrary signal generator in described backup signal resource or described display source signal is not received if detect, then determine that corresponding signal source occurs abnormal, such as, if do not receive the bit stream data of the signal source A in described backup signal resource, then determine that signal source A occurs abnormal, if do not receive the bit stream data of the signal source B in described display source signal, then determine that signal source B occurs abnormal,
