Abstract
Broadcast television signal includes two classes: digital and analog. The invention includes following steps: (1) when monitoring computer (MC) has monitored faults that dark field, silence frame, and lost video etc illegal signal disturb, and too large or small sound exist in video and audio signal of analog signal from satellite receiver (SR), fiber optic receiver (FOR), or bandwidth, PCR and PSI/SI indexes of digital broadcasting TV (DBTV) signal occur clear change; (2) MC sends command of switching off power supply automatically to power supply system of signal source devices of corresponding SR, FOR etc; (3) switching standby signal to DBTV multiplexer or analog broadcasting TV modulator etc in corresponding defective channel; (4) software of MC instructs sound card to send trouble alarm voice in corresponding channel; (5) after determining that illegal signal is removed, the watch turns on power supply system of SR or FOR by hand, and MC executes monitoring operation again.
Description
Technical field
The present invention relates to radio and television safety and broadcast the field, relate in particular to a kind of illegal signals that prevents and enter the control device of radio and television playing device.
Technical background
Current, the lawless person broadcasts at the safety that the illegal signals of radio and television is attacked the serious threat radio and television, and the invasion of taking precautions against illegal signals is the cardinal task of broadcast television industry.At each Headend machine room, the signal source is satellite radio television program, optical cable transmission program and manages program by oneself, whether value crewman is normal in the absorbed TV programme of dig-inning, the shortcoming of this manual supervisory mode is, in case find illegal signals invasion or line fault problem, generally take manually to go to turn off the method for equipment such as satellite television receiver, optical receiver, often owing to factors such as the slow motion of selling, thought paralysis, mood absent-mindedness have been incured loss through delay the time, cause the broadcast of illegal signals, cause great negative effect.Control device of the present invention can be monitored before entering playing device the broadcast TV program signal of all channels, and had automatic cut-out illegal signals, with the temporary transient function of broadcasting of interim space signal.The use of this invention has guaranteed that the radio and television front end broadcasts the fail safe in machine room signal source.
Summary of the invention
The present invention is directed to radio and television safety and broadcast upward ubiquitous problem, purpose is to provide a kind of illegal signals that prevents to enter the control device of radio and television playing device.
The public technology scheme is as follows:
A kind of illegal signals that prevents enters the control device of radio and television playing device, and broadcast television signal comprises numeral and simulates two kinds.It is characterized in that may further comprise the steps:
A. in supervisory control comuter monitors video and audio signal from the analog signal of satellite receiver, fibre optic receiver etc., there are illegal signals such as Hei Chang, quiet frame, video-losing to disturb and the excessive fault such as too small of sound, perhaps monitor index generation significant changes such as bandwidth, PCR and PSI/SI when supervisory control comuter from the digital broadcasting-television signal of satellite receiver, fibre optic receiver etc.;
B. supervisory control comuter is to order shutoff signal source that signals such as the satellite receiver of correspondence or fibre optic receiver come the electric power system of source device to send to turn off power supply automatically;
C. space signal is automatically switched to playing devices such as the digital broadcast television multiplexer of the corresponding channel that breaks down or analog TV broadcasting modulator rapidly;
D. the sound card of the software of supervisory control comuter indication supervisory control comuter sends the voice fault alarm sound of corresponding channel.
E. be worth after the crewman confirms that illegal signals is got rid of, the electric power system of signal receivers such as the satellite broadcasting television receiver of manual unlocking correspondence or fibre optic receiver, monitoring computer is carried out monitoring once more.
Description of drawings
Fig. 1 is the equipment connection diagram.
Fig. 2 is overall process flow figure of the present invention.
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the connection diagram of present device.
Supervisory control comuter is connected with the signal receiver electric power supply control system by USB or RS232 interface, receiving equipment is connected with supervisory control comuter by looking voice-frequency cable, receiving equipment is connected with playing device by video and audio equipment, and playing device is connected with the backup signal source that supervisory control comuter provides by looking voice-frequency cable.
Fig. 2 shows overall process flow figure of the present invention.
In step 201, signal derives from satellite receiver, fibre optic receiver and manages broadcast TV program by oneself.
In step 202, supervisory control comuter receives and monitor signal.
In step 203, supervisory control comuter judges whether it is illegal signal, criterion mainly is, have or not illegal signals such as Hei Chang, quiet frame, video-losing to disturb in the video and audio signal of analog signal and sound excessive too small etc., whether indexs such as the bandwidth of digital broadcasting-television signal, PCR and PSI/SI significant change takes place.
In step 204, judged result is not illegal signal, then exports signal to playing device.
In step 205, judged result is illegal signal, and supervisory control comuter sends cut-offing instruction to the receiving equipment electric power system.The receiving equipment electric power supply control system adopts single-chip microcomputer or the exploitation of ARM7 flush bonding processor, when single-chip microcomputer or ARM7 receive the automatic cut-offing instruction that supervisory control comuter sends by USB or RS232 interface, uses controller such as relay to cut off the receiving equipment power supply.
In step 206, supervisory control comuter exports the signal source automatic switchover of backup to playing device.The signal source of backup can be to be stored in the various video/audio signals of supervisory control comuter and the simulation or the digital broadcasting-television signal of other equipment.
In step 207, supervisory control comuter sends fault alarm sound by sound card.Alarm sound is the various format audio files that are recorded in each the corresponding channel in the supervisory control comuter hard disk.
In step 208, value crewman works on receiving equipment after confirming that fault is got rid of.
Promptly finish once monitoring by above step.In the present invention, by the reliability of having guaranteed to export to the playing device signal for mode that the outage of illegal signals source device, supervisory control comuter switch interim backup signal source, the maintenance efficiency of not only having avoided the broadcast of illegal signals but also improved radio and television to broadcast from the source.
It will be appreciated by those skilled in the art that, supervisory control comuter can be one or more of computer workstation, server, personal computer, and supervisory control comuter is supported the DVB-C standard to look the input and output of audio frequency, radiofrequency signal, supports the input and output of ASI signal, supported multiple signals to monitor simultaneously.This invention is applicable to that front ends such as TV and Radio Service, wired broadcasting TV network company broadcast machine room.
Within the spirit and principles in the present invention, any modification of being done, be equal to and replace improve etc., all should be included within protection scope of the present invention.
