The broadcast signal grading automatic control device realizes grading broadcast control by utilizing an electric automatic control system, ensures the timeliness of information transmission, automatically grounds an outer line when the broadcast is stopped, and ensures that the outer line does not invade the broadcast system to damage equipment when the outer line is landed. The working principle of the broadcast signal grading automatic control device is as follows: when the intelligent power supply works, the breaker QF main power supply is normally closed, and the power supply indicator RD1 lights up to indicate that the control system is electrified. When any one set of program is started, the first relay to the third relay are powered on and closed, the
The receiving and transferring program (KM1) and the self-handling program (KM2) are interlocked, an L2 power supply is controlled by the outside, when the L2 is electrified, a coil KM1-1 of a receiving and transferring program power supply contactor is switched on, a 103 wire (namely a normally open contact KM1-2 is closed) is electrified, a loudspeaker is switched on, and a receiving and transferring program signal is directly externally discharged through the loudspeaker and a first relay, a second relay and a third relay. When the radio program is played, the normally closed contact KM1 is opened 106-107 (i.e. the normally closed contact KM1-4 is opened), so the self-made program can not be opened. When emergency broadcasting exists, the coil KM3-1 of the emergency broadcasting power supply contactor is powered on, 109 and 110 are disconnected (namely the normally closed contact KM3-4 is disconnected), the coil KM1-1 of the project receiving power supply contactor is powered off, and the KM3 is used for controlling the broadcasting of the emergency broadcasting. When the receiving and transferring program (KM2) is played, the working state of the receiving and transferring program is indicated through an indicator lamp RD2 for local control personnel to refer to.
When the self-office program is not started up during receiving and switching programs, the manual button AQ is pressed, the normally closed contact KM2-4 is powered on and closed and is kept by the normally open contact KM, 103 and 104 (namely the normally open contact KM2-2 and the normally open contact KM2-3 are closed) are powered on, and the loudspeaker, the sound console and the signal processing equipment are all connected to play local signals. When the self-office program is played, the KM2 normally closed contact is used for disconnecting L2-109 (namely the normally closed contact KM2-5 is disconnected), and the roll-in program cannot be opened. When emergency broadcasting is available, KM3 is powered on, 107-108 (namely normally closed contact KM3-3) is disconnected, coil KM2-1 is powered off, and emergency broadcasting power supply contactor is used for controlling the broadcasting of emergency broadcasting.
The emergency broadcast has the highest priority, and when L1 is powered on through a telephone loop, KM3 is directly conducted, and the receiving and rotating program KM1 and the self-handling program KM2 are disconnected through the normally closed contacts of the KM3, so that the broadcasting is interrupted, and meanwhile, the emergency broadcast signal is directly broadcast and broadcasted through a loudspeaker. When the emergency broadcast of the telephone line is broadcast, the working state of the emergency broadcast is indicated through an RD3 indicator lamp and is referred by local control personnel.
The broadcast signal grading automatic playing control device can automatically control broadcast output according to signal class grading. When the automatic control power supply of various signals exists, the priority level is automatically identified, and the signal broadcast with the highest priority level is broadcasted; automatically inputting corresponding signal output routes according to various signals; the work of the external circuit is automatically converted into the grounding, so that the lightning protection of the external circuit is realized. The broadcast signal grading automatic playing control device can realize the functions by adopting a plurality of simple electronic components and a designed smart circuit, and has the advantages of simple and smart structure, low cost, low later maintenance cost and convenient maintenance. The invention uses mature low-cost electric control elements to reliably realize the control function of the invention for a long time without programming.
