The present invention is a multi-family house, especially in a large apartment complex with thousands of households, such as general announcements, emergency broadcasts such as fires, emergency broadcasts from the apartment central management office and each household, apartment central management office and each guard room. The present invention relates to an apartment general broadcasting system that allows various broadcasting programs in the apartment complex, such as directed broadcasting, security offices, and inter-phone broadcasting between households on each floor.

In the present invention, the broadcasting control equipment of the main control room (control room) in the apartment complex, the intercom facility of each security guard of the apartment, and the arbitrary location of the apartment (each household, underground parking lot, outdoor playground, etc.) are connected to each other through the broadcasting network. Remote microcom amplifier installed in guard room of apartment building by remote interface (RI) in local interface (LI ₁ ~ LI _n ) installed in guard room of apartment building with main interface (MI) to main control (MC) controlled by computer (1) (RMA _{1 to} RMA _n ) to be configured in succession, the main control (MC) is connected to each of the process logic (PL ₁ ~ PL _n ) connected to each fire receiving panel (2) in one-to-one process control (PC), respectively The main control (MC) is configured in succession, the local interface (LI (R)) for controlling other places such as outdoor playground, underground parking lot, etc., and the main control (MC) Signals that control signals such as central remote micom amplifiers (RMA _c ) microphones (3), AM / FM tuners (4), cassette techs (5), chime or alarm generators (6) The changer SE is configured in succession.

In the above, the emergency power unit (UPS) is installed in each unit and each guard room. In addition, in the above, the local interface LI _{1 to} LI _n of each management room are connected with the main interface MI and connected to the main control MC, while the main control MC has a signal exchanger SE and a main interface MC. It is connected to various signals (broadcastings) generated through the microphone (3), alarm sound generator (chime) (6), AM / FM tuner (4), and cassette tech (5) in the main office. , Underground parking lot, outdoor playground.

In the above, each of the computer (1), the process control (PC), the remote control (RC), the main interface (MI), the signal changer (SE) and the local interface (L1) connected to the main control (MC), respectively, RS RS-485 connection between the main interface (MI) and the local interface (LI _{1 to} L1 _N ) of each building, and the remote interface (RI) to the remote control unit (RMA _{1 to} RMA _N ) of the building, etc. Each process logic PL _{1 to} PL _N connected to each fire receiving panel 2 in a 1: 1 connection is also configured to be connected to the process control PC in a 1: 1 manner.

The present invention configured as described above can be individually broadcast by opening the speaker of any desired place (apartment generation, underground parking lot, outdoor playground, etc.) by the computer (1) keyboard or control board (CB) of the main management room. You have the advantage to do it. In addition, the place where the broadcast is displayed on the LCD, which is the display window of the display board (DB) of the main control (MC), it is easy to determine the place where the broadcast.

In a conventional facility, since the desired place was identified by using a flashing light using an on / off switch, a light bulb, or an LED, the equipment was large in size as many as the blinking light, and the place broadcasted by the naked eye could not be easily grasped. However, in the present invention, since the place broadcasted to the display device DB is displayed on the LCD screen which is the display window, the place broadcasted can be grasped at a glance.

In addition, in the conventional broadcasting facilities, control lines are individually required for remote broadcasting. However, in the present invention, the RS-485 method is adopted, so that up to 31 multi-control broadcasting can be performed in parallel.

In addition, in the conventional broadcasting system, in order to broadcast in the central control room, each speaker line is connected to each household of each building and directly connected to the amplifier output of the central control room. a local interface (LI ₁ ~LI _N) and only ever install the speaker line from the local interface (LI ₁ ~LI _N) of gakdong by central control room to the amplifier output line and the two lines are Popondetta 4 lines as RS-485 manner The number of lines is significantly reduced by multi-configuring the control cables in parallel.

In addition, the fire detection system in the conventional apartment complex is composed of a logic matrix using an analog method to detect a fire, display the operation state by LED, and to control the speaker, but in the present invention, using a digital method It was coded to detect fire, display letters on the LCD and control the speaker so that the place of fire could be identified at a glance.

The summary of the operating system of the present invention is as follows.

In other words, the priority of broadcasting in the present invention,

1. Fire broadcasting (emergency broadcasting)

2. Management Room Broadcasting

3. Central broadcasting

4. Security Room Broadcasting

The broadcast equipment according to the present invention controls and manages up to 31 buildings, 8 stairs and 30 floors, that is, 7440 households and their associated facilities (parking lot, playground, etc.), according to the broadcasting priority. It is possible to control which stairs and which floors. In addition, it is possible to control floors through the central broadcasting only during an emergency such as a fire.

The broadcasting system according to the present invention can be controlled by a computer, and the current broadcasting status can be grasped at a glance because the broadcasting points and types of broadcasting (fire broadcasting, management room broadcasting, central broadcasting, remote broadcasting, etc.) appear on the display screen. Will be.

According to the present invention, the process of performing a fire broadcast in case of fire is as follows.

When the signal of the fire detector in the place of fire is input to the fire receiving panel (2), the fire signal input to the process logic (PL) connected 1: 1 with the fire receiving panel (2) is analyzed and coded by the process control (PC). Then, when the main control (MC) is transmitted, the main control (MC) transmits the value, that is, the place where the fire is transmitted to the display board (DB) to write on the LCD display window, at the same time the main control (MC) A fire signal is sent to the local interface (LI) of the apartment in the fire to open the speaker of the fire floor and stairs, and the main control (MC) drives the signal changer (SE) to generate a fire signal and power The amplifier amplifies it and transmits it to the local interfaces (LI _{1 to} LI _n ) provided in each building to make a fire signal (alarm sound or contrast broadcast) to the mentioned open speaker.

In the present invention system, the place of fire is automatically displayed on a display board (DB) or a computer screen, so that the place of fire can be easily identified, and quick follow-up is possible.

However, in the conventional apartment broadcasting facilities, the place where the fire occurred was only displayed by blinking lights, and the equipment had to be very large. Since the central control room and the apartment buildings were connected to each household line, hundreds of thousands of wires were required. However, in the present invention, the local interfaces (LI _{1 to} LI _n ) are mounted on the corners, the local interfaces (LI _{1 to} LI _n ) and the main control (MC) are connected digitally with a line, and the local interface (LI _1). -LI _n ) and amplifier (Power AMP) can establish a broadcasting network with only a dozen wires when laying lines in an analog manner.

That is, as shown in FIG. 2, a signal transmission method uses a digital transmission method (see dotted line in the figure) and a sound transmission method uses an analog transmission method (see solid line in the figure). It was possible to build.

Hereinafter, a description will be given of the process of performing the management room broadcasting and the central broadcasting of general broadcasters.

If you designate a location to be broadcasted on the control board (CB) of the computer (1) or the main control (MC), the place to be broadcasted is displayed on the screen of the computer (1) or on the display board (DB). The speaker of the interface LI or LI (R) is opened and the signal exchange SE is driven and simultaneously broadcasted, that is, the microphone 3 or the chime 6 radio 4 or the cassette ( The signal generated from 5) is amplified by the PRE AMP and the POWER AMP and output to the speaker of an arbitrary place already opened by the local interface LI, that is, to be broadcast. The broadcast is also displayed on the computer screen or the display board (DB), the type of broadcast and the content of the broadcast can be confirmed at a glance.

Referring to the operation of the main control (MC) through the flow chart of the main control (MC) shown in Figure 6 in the present invention operated as described above are as follows.

That is, the initial value replaces the constant OK with hexadecimal 0x7F, REQ with hexadecimal 0x7D, START with hexadecimal 0x9O, and ENF with hexadecimal 0x80, and initializes N and CH to 0 as variables. . Variables here are spaces that can be temporarily stored. In the above description, the OK value is the recognition data of the receiving side for the 8-byte transmission formed at the input terminal, and the REQ is a DATA value which asks whether or not DATA is formed at each input terminal in the main control MC.

STRAT is the first data value of 8 bytes generated when input data is formed at the input terminal, and ENF is the value transmitted from the input terminal as a response to the REQ in the main control (MC) when there is no data at the input terminal. . In addition, DATA [20] [8] refers to a two-dimensional array memory space that can be stored when 8 bytes of data are received from the input terminal.

The main control (MC) sends the data request signal (REQ) one by one to the control board (CB), input switch, remote interface (RI), and process control (PC) one by one. Temporarily store and compare the CH value with the START value set by the constant. If it is different, only compare the CH value and the ENF value set by the constant, and move to S ₁ to check the input data of the other input. If CH is equal to START, 8 bytes including the value stored in the first CH are received from the input terminal and stored in the space DATA [N] [8] where 8 bytes can be stored, and N = N + 1 to save the next input DATA. Moves the memory address to the specified storage location.

Then compare N and 1, and if it is different, go back to S ₁ to check the input data of the other input stage, and if it is the same, two-dimensional to the local interface (LI _1- LI _N ) that manages the outside of the apartment building. Send the first 8 bytes of input data [0] [8] stored in the array memory space, receive 1 byte of data transmitted from the output terminal, store it in the temporary storage space CH, and save the saved CH value and OK value determined by the constant. If it is different, the data error processing is performed. If the data is different, the data of the first input data DATA [0] [8] stored in the process control (PC), signal interrupter (SE), remote interface (RI), and control board (CB) are compared. 8Byte input data is stored and the data values are saved one step forward from the current position, and by transmitting, one data input at the input terminal is completely processed. N = N-1, which means the input data storage address, Moves to the previous address and returns to S ₁ to check the input data of the next input. In the main control (MC) it will be repeatedly performed. In addition, the main interface MI of the present invention operates in the order of the flowchart shown in FIG.

DATA [8] is an 8-byte memory storage for storing what is input to the main control (MC) at the input and sent back from the main control (MC) to the main interface (MI). If there is an input DATA from the main control (MC), one byte sent from the main control (MC) is stored in CH, which is a temporary storage location for data, and CH value is compared with the START value set by the constant. Return to S ₂ to check whether there is any DATA transmitted from MC), and if it is equal, store 1Byte DATA stored in CH in DATA [] which is a memory space that can store 8Byte DATA.

And sent to the 8Byte DATA stored in the DATA [] at the same time, the local interface (LI ₁ ~LI _N), and then stores the DATA 1Byte been sent back from the local interface (LI ₁ ~LI _N) on the temporary storage area DATA and CH When comparing CH value and OK set by constant, it returns to S ₂ if it is different, and if it is equal, 1 byte of OK value is transmitted to main control MC to process the applied signal from input terminal.

FIG. 8 is an interrupt subroutine of the remote interface RI. When 1Btye DATA is transmitted from the main control MC, an interrupt is generated, and the 1Byte DATA transmitted is temporarily stored in the CH which is a temporary data storage location.

Then, if the CH value is compared with the START value set as a constant, if it is equal, it receives 8Btye DATA including 1Btye stored in CH and stores it in a specific memory, and stores 8Byte DATA and the first 8Byte DATA [0] [ If it compares with 8], only the DATA is stored in the current broadcasting information memory, and then the subroutine is finished, and if it is the same, the Remote Interface (RI) uses the 8-byte DATA [0] [8] input from the input terminal. Remote interface (RI) interrupt by transmitting to RMA, pulling N, which means input data storage address, to N = N-1, that is, pulling one step forward, and then storing and managing the current broadcasting status DATA value in the current broadcasting information memory. Finish the subroutine.

If the CH where 1 byte is stored is different from the START value set as a constant, it is judged again by comparing CH with the REQ value set as a constant. If it is different, the subroutine ends. The ENF DATA is transmitted, and if it is different, the subroutine is completed by sending 8 bytes of DATA [0] [8] inputted at the input terminal to the main control (MC).

In addition, the remote interface RI of the present invention operates in the order of the flowcharts shown in FIGS. 8 and 9.

In other words, K is a changing Remote Micom amplifier (RMA) address value in the state of START = 0x90, ENF = 0x80, DATA [31] [8], CH = 0, N = 0, and K = 1. Send the address data of RMA K to remote micom amplifier (RMA) K, receive 1 byte of data from remote K, and store it in CH, a temporary storage location. If the CH value is compared with the START value determined by the constant, if it is different, the CH value is compared with the ENF value again.

If the CH value where 1 byte is stored is equal to the START value set as a constant, 8 bytes including 1 byte of data stored in CH are stored in DATA [N] [8], and the storage cursor N is increased by 1 and the remote address value is increased by 1. do.

So, compare K and 32 value, if it is different, return to S3-1, if same, set K value to 1, the first remote address, and then transmit the current broadcasting information stored in memory to all remotes collectively and return to S3-1. Goes.

The flowchart of the timer interrupt shown in FIG. 10 is as follows.

When an interrupt occurs, first set TRO = 0 to stop the timer interrupt. If you set ZERO to TRO, the timer interrupt stops. After that, 1 is added to Ti-Cnt, which calculates the time, and stored again in Ti-Cnt. Then, Ti-Cnt is initialized to 0 and the input data is error-processed by comparing Ti-Cnt with 30.

Then, it checks whether there is another input data and if it is not finished, transmits 8 bytes of input data, and then enables and terminates the timer interrupt. If Ti-Cnt is not 30, it checks whether the transmitted data is returned and initializes Ti-Cnt to 0 and ends. Otherwise, the timer interrupt is enabled and finished.

The flowchart description of the local interface LI shown in FIG. 11 is as follows.

After finishing the serial port and various data initialization operations, the local interface LI continuously checks whether there is data received from the main interface MI. If there is data received, it first receives 1 byte of data and stores it in the memory space, that is, the variable CH. Then, the value of CH is compared with the value of the settlement constant START by some value, and if it is different, it returns to S ₁ , and if it is equal, 8 bytes including 1 byte of data stored in CH are received from the main interface MI, and the memory of the local interface LI is Store in Then, it compares whether the received 8-byte input data is the data of the local interface LI itself. If it is not its own data, it returns to S ₁ , and if it is its own data, the local interface LI transmits 1 byte of recognition data having a value of OK to the main interface MI. Then, by comparing and judging the received 8 bytes of DATA, the relay corresponding to each data is driven and returned to S ₁ , which is the first operating point, thereby completing the operation of the local interface LI for one input data.

The flowchart description of the process control PC shown in FIG. 12 is as follows.

The process control (PC) initializes the serial port and various data first, and then each GATE terminal that indicates whether a fire has occurred and compares the previous GATE terminal status with the current GATE terminal status until it is the same. If it is different, it analyzes the changed GATE terminal and forms 8 bytes of data that meets the communication protocol and stores it in memory. Then go back to S1 and compare the GATE terminals.

The flowchart of the control board CB shown in FIG. 13 is as follows.

The control board (CB) first performs interrupt and serial port initialization and liquid crystal display initialization. The initial screen is displayed on a liquid crystal display (LCD). Then, among the current broadcasting information memorized and stored, the fire broadcasting information is first examined and displayed on the LCD, and the management room broadcasting information is then displayed on the inspection LCD. In addition, it checks the data in the order of central broadcasting information, remote broadcasting information, and shows the current broadcasting information on the LCD. After checking the current broadcasting information, if there is no data to display on the LCD, the initial screen data is displayed on the LCD and the screen returns to S ₁ . If there is data, just go back to S ₁ .

The flowchart of the signal exchanger SE shown in FIG. 14 is as follows.

The signal exchanger (SE) first completes the serial port and various data initialization operations, and then continuously checks until there is data received from the main controller (MC). If there is received data, 1byte of data received in variable CH is saved. Then, the value of the saved CH is compared with the constant START, and if it is different, it is returned to S ₁ , and if it is the same, 8 bytes of data are received and stored in the memory from the main control (MC) including 1 byte of data stored in the CH. Then, by comparing and judging the received 8 byte input data, the signal abatement relay for each data is driven to finish the received 8 byte of input data and return to S ₁ to receive another input data.

The flowchart description of the external interrupt at the key input shown in FIG. 15 is as follows.

When an external interrupt occurs, it is stored in the external interrupt disable key input value memory.If the key input value does not correspond to the reference value, the controller terminates by enabling the external interrupt while processing the input key value. If the key input value corresponds to the reference value, the buzzer For 0.5 seconds and temporarily store the key values in the specified memory.If the stored values are not entered in the specified order, enable the external interrupt while processing the entered key values, and determine if the entered values are entered in the specified order. Is stored in each memory and finished with external interrupts enabled.

16 is a flowchart of a serial interrupt used in all units except the process control (PC).

If a serial interrupt occurs, first stop the serial interrupt, and then store the received 1 byte of data in the variable CH, compare the CH value with the constant START value, and compare the CH and REQ values again. After it finishes, if it is equal, it checks for its own input data, if not, sends a constant ENF value, then makes the serial interrupt possible and ends. Otherwise, if there is its own input data, it sends 8 bytes of input data, enables timer interrupt and serial interrupt and ends.

If the CH value and the START value are the same, 8 bytes including the CH value are stored in the memory. Compares the stored data and saves it in each memory again. If the received 8 bytes of data is its own input data, stops the timer interrupt, cleans up the input data, and then enables and ends the serial interrupt. If not the data itself, just enable the serial interrupt and exit.

The flowchart description of the serial interrupt of the process control PC shown in FIG. 17 is as follows.

If a serial interrupt occurs, first stop the serial interrupt and save one data in the variable CH, then compare the CH value with the constant OK value, compare the CH and REQ0 again, and make the serial interrupt possible if it is different. After checking if there is input data, if not, transmit constant ENF value to MC, then enable serial interrupt and finish. Otherwise, if it has its own input data, it sends 8 bytes of input data to MC, enables timer interrupt and serial interrupt and ends. If CH and OK are the same, the input data memory is cleared, initialized as transmittable, the serial interrupt is enabled and finished.

The flowchart of the remote microcomputer amplifier (RMA) shown in FIG. 18 is as follows.

The remote micom amplifier (RMA) first performs various initialization operations and then displays the initial screen on the liquid crystal display. Then, if the mode is analyzed and the ZERO MODE is displayed, the current broadcasting information is displayed on the liquid crystal display and the display returns to S ₁ , or the self input broadcasting information is displayed on the liquid crystal display, and then the display returns to S ₁ . Here the MODE switch is switched between serial and key interrupts.

The present invention adopts the full duplex method with a communication speed of 9600BPS, and transmits the input data by forming 8 bytes. Communication protocol consists of start, information, function, building, stairway, floor, parking lot, outdoor, and end. It adopts RS-232 serial multi communication method from main control (MC) to each unit, and from remote interface (RI). Each remote micom amplifier (RMA _{1 to} RMA _N ) uses RS-485 multi-communication method and RS-485 multi-communication method to control each floor speaker gate from each local interface (LI _{1 to} LI _N ). .

In addition, up to 31 remote mic amplifiers (AMP _{1 to} AMP _n ) are installed in the guard rooms of each building, and if you want to broadcast to each household, turn on the power switch and turn on the keys of the building, stairs, floor, parking lot, and other outdoor areas. To operate the broadcast. Each of these remote microcomamps has their own designated zones, so they can broadcast their own zones, and if desired, they can broadcast to all zones they want to broadcast, based on their broadcast priority.

In addition, if control is input from the central broadcasting while broadcasting the own zone, the remote amplifier of the zone corresponding to the control portion is stopped and enters the control of the central broadcasting. After that, when the central broadcasting is finished, the guard room broadcasting system is turned on again so that local broadcasting can be started.

In this way, the present invention can simultaneously perform the central broadcasting from the parking management room and the regional broadcasting covering the respective areas of each building, and in the event of an emergency such as a fire, it may separately or automatically generate a broadcasting or alarm sound.
