As shown in fig. 1-2, the utility model discloses an emergent early warning broadcasting system of wireless public network, including double-circuit signal diversity reception controller 1, can effectively receive singing and china wired network and 4G wireless mobile public network transmission's two way broadcast signal to village level broadcasting equipment, double-circuit signal diversity reception controller 1's receiving terminal of the same kind is connected with cable television network frequency modulation signal end 2, cable television network frequency modulation signal end 2 is connected with double-circuit signal diversity reception controller 1 through decoding controller 3, decoding controller 3 is CATV FM decoding controller. The cable television network frequency modulation signal is decoded by the decoding controller 3 and then processed by the two-way signal diversity receiving controller 11, and then broadcast by the loud speaker 6 and the loudspeaker 7, which is a single-line networking mode applied to most village-peaceful broadcast at present, but the single-line networking has many problems, so the second-line networking mode and the two-way networking mode are added in the cable television network.

Another way receiving terminal passes through wireless communication module and is connected with control system 5 communication, wireless communication module is 4G network decoding adapter 4, adopts wireless 4G mobile public network transmission mode, and the second way networking mode can also be used to urgent early warning, insert early warning information, increases wireless networking all the way on the wired basis, increases the reliability. The output end of the double-channel signal diversity reception controller 1 is connected with the loud speaker 6, the loud speaker 6 is connected with the loudspeaker 7, the audio signal after double-channel decoding is played through the loud speaker 6 and the loudspeaker 7, the loudspeaker 7 is provided with the return monitor 8 for detecting the state of the broadcasting equipment, namely, state information of 'start broadcasting' is sent to the wireless communication module, when no output exists, state information of 'end broadcasting' is sent, the two state information is timely returned to a platform of the command center 12, so that managers can master the real-time broadcasting condition of each terminal station, and the return monitor 8 is in communication connection with the control system 5 through the wireless communication module. When broadcasting is carried out in a village and a town, if a certain village is not broadcasted, the real-time online broadcasting monitoring module embedded in the broadcasting equipment of the village can immediately and automatically send back state information (states of power on/off and the like) to the network cloud server, and the broadcasting working states of all villages can be seen on a computer display screen of a control platform of a broadcasting station of the town in real time, so that related managers can be effectively assisted to supervise and urge the networking work of the broadcasting equipment of the village in time, the phenomenon that the broadcasting signals of upper-level stages are missed due to human factors or equipment faults of the village which is not on-line or the village which is not rebroadcast in time is ensured to be found in time when major tasks are broadcasted.

The control system 5 comprises a network server 11, a command center 12 and a telephone emergency broadcast controller 10, wherein the command center 12 is a computer, the telephone emergency broadcast controller 10 is used for broadcasting contents of telephone and short messages, the network server 11 is connected with a wireless communication module, the command center 12 and the telephone emergency broadcast controller 10 are both connected with the network server 11, the network server 11 is connected with a network monitoring sound box 14 and a digital network broadcast control console 15 through a router 13, the network monitoring sound box 14 is used for monitoring broadcast information by the command center 12, and the telephone emergency broadcast controller 10 is connected with a telephone 16.

The two-way signal diversity reception controller 1 and the loudspeaker 6 are both connected with a power protector 9. The power protector 9 is an intelligent power protection controller KDMA-2B, can effectively protect the loudspeaker for villages, automatically detects when an external line short circuit fault occurs, gives an alarm through voice prompt tones, and simultaneously protects the loudspeaker from being damaged.

No matter the terminal is used by itself or the superior broadcast terminal is networked, or the terminal is connected with the network through the cable television network or the 4G cloud broadcast, only the terminal outputs the broadcast signal, and the broadcast signal can be automatically transmitted back to the platform of the control center in real time through the 4G cloud broadcast at the first time.

In order to improve the transmission efficiency and reduce the communication charge, the technology adopts the working state of only outputting the terminal audio frequency, such as 'several points of power release/several points of power release switch'; or the state of 'a few minutes of broadcasting start/a few minutes of broadcasting end' is sent back to the cloud platform control center in real time, so that managers can conveniently look up and look over at any time.

The power identification of the real-time return signal can also be designed arbitrarily through a program, for example, when the output power of the tail end is set to be more than or equal to 50W in the existing system, the real-time return signal is sent back to the cloud platform control center, and when the output power of the tail end is less than 50W, the state signal of 'several minutes of power release' is not sent. The purpose of this design is to ensure efficient delivery and monitoring of the networked broadcast. If some end users do not want to relay the networking broadcasting, the volume of the loudspeaker at the rear end is turned off, the information transmission channel of the 4G 'cloud broadcasting' works normally, and the platform can display information such as normal working of the system, so that the 'broadcast missing' condition caused by human factors can be easily caused. The function is added to ensure a powerful technical monitoring means for real terminal broadcast startup broadcasting. Only when two pieces of information are simultaneously established, the information which is broadcasted in a network can be broadcast accurately. It is understood that what is called "information" feedback function in the market is only staying on the information channel, and whether the real end loudspeaker plays the broadcast information is unknown, which is also the reality that we find and improve from practice.

The main functions of the diversity reception controller are:

when the same information reaches a receiving terminal through two transmission modes (a wired network or a 4G network), the diversity receiver automatically judges which level is high (the inside of a circuit and a program have the priority identification and control function, and can also arbitrarily set which working mode is the higher level) and preferentially executes the communication information; similarly, when two communications transmit different information, the transmission is still selected according to the priority of high level; and temporarily hang up the path with low level of transmission first, and continue to transmit the low level channel after the transmission of the high level channel is finished.

And secondly, when two paths of information are transmitted, the controller also automatically judges the current information intensity, if the information quality of one path is poor, the controller also automatically switches to the other path with good signals, and the aim of ensuring the reliable transmission of the information is also achieved.
