Job applications：
By taking broadcast terminal is multimode sound column as an example, five signal receiving channels are shared, the priority of setting is DTMB>DVB-
C>IP>FM>4G, in the place that some remote rural areas or physical features are more dangerously steep, when carrying out broadcast system construction, multimode sound column
It is connected the collection of letters number it is necessary to be laid with a large amount of circuits with superior platforms according to wired, increases construction cost, due to multimode sound column
The collection of letters number that is wirelessly connected with superior platforms can be used, avoids the need for being laid with a large amount of circuits, it is only necessary to add in superior platforms
Launch recoil simulator.
Meanwhile multimode sound column has five signal receiving channels, when one of signal receiving channel goes wrong, Ke Yixuan
With remaining four signal receiving channels, avoid information from propagating and delayed, especially when some natural calamities occur, such as
Earthquake, the one side for delaying the condition of a disaster are exactly that information propagation ducts are destroyed, and cause information not propagate, and the delay disaster relief is taken refuge.But
It is that multimode sound column can take other passages in the case where partial information propagation ducts are destroyed, farthest reduces letter
Cease the delay propagated.
In addition, priority DTMB is taken in reception of the multimode sound column to signal>DVB-C>IP>FM>4G, when running into disaster
When, set according to priority, multimode sound column meeting preferential answering DTMB signals, secondly DVB-C, is IP again, then
It is FM, last 4G.When the forward signal source of priority can not be transmitted, the lower signal source of priority, phase can be jumped to automatically
Compared with the single-mode receiving terminal of the prior art, it can preferably ensure that emergent broadcast operates.
Above-described is only the preferred embodiment of the utility model, it is noted that general in the art
For logical technical staff, on the premise of core technical features of the present invention are not departed from, some improvements and modifications can also be made, this
A little improvements and modifications also should be regarded as protection scope of the present invention.
