Description

Speaker individual control system and broadcasting system using same {Speaker control system and broadcasting control system}

The present invention relates to a system for controlling a speaker used for indoor, outdoor broadcasting, or a similar purpose, and more particularly, a controller capable of transmitting / receiving a signal for each speaker and controlling a connection with an amplifier. By attaching and connecting this controller to a computer, the present invention relates to a speaker individual control system and a broadcasting system using the same to enable speaker operation control and abnormality determination in a GUI environment of a computer.

In general, in a building having a large number of compartments, such as a school or a factory, speakers are installed in each space in order to deliver a message to the people in each space. Take a look.

1 is a block diagram showing a conventional speaker installation state, a plurality of speakers 12 are connected to the amplifier 14 and two signal lines each containing voice information.

Accordingly, when there are speakers 12 that do not want to be broadcast among the speakers 12 connected to the amplifier 14, a worker must manually separate a line connecting the amplifier 14 and the corresponding speaker 12. When not manually separated in this way, the signals output from the amplifier 14 are simultaneously output to all the speakers 12, so there is a problem that the corresponding signals are also output to the speaker 12 that is not desired.

An object of the present invention for solving the above problems is to control the operation of the speaker by attaching a controller capable of transmitting / receiving signals for each speaker and controlling the connection with the amplifier and connecting the controller with a computer. And it is to provide a separate speaker control system to enable the determination of the abnormality in the GUI environment of the computer.

In addition, another object of the present invention is to provide a broadcast system including the speaker individual control system to control the output of the audio / video output device through a computer.

The DC 9V power supplied through the power supply jack 1 is changed into a DC 5V voltage through the constant voltage circuit D and supplied to the circuit. Then, the control signal of the PC and the signal indicating the state of the speaker itself are transmitted and received through the external connection jack (2), and the control signal received from the PC is received through (D) in FIG. It transmits the speaker's own status.

Whether or not the input voice signal (C) is output (B) through the connection jack 3 with the speaker is determined by the relay switches TQ2-5, a, which are relayed from the PC. It is controlled by the command, which is finally executed, and if the operation stops due to the abnormality of the broadcasting system, the power supply of the relay switch (a) is cut off so that it becomes the contact point b rather than the contact point a state, without the control of the system. Only the function of the amplifier enables broadcasting.

In addition, microprocessors (AT89C51, B) are provided to store unique IDs, and converters (MAX484, bar, company) are installed to transfer RS232C signals to the microprocessors B to convert RS485C signals to RS232C signals.

In addition, since the dip switch (C) creates a unique ID using an 8-bit bit string and transmits the unique ID to the microprocessor (B), the microprocessor (B) can recognize 8-bit speakers, depending on the installation environment. It is possible to increase or decrease.

The microprocessor (B) is monitored by the reset circuit (A) and automatically resets when an abnormality is found. When the administrator judges a circuit error by using a separately provided reset switch (E), the computer After determining whether there is an error on the screen, you can manually execute the reset function.
