In addition, although not shown, the receiver server 100 may be constructed to send out whether a fire has occurred through the Internet 150 to the set fire control center.

The receiver server 100 is constructed in a conventional computer structure and an example is shown in FIG.

Referring to FIG. 2, the receiver server 100 includes a main controller 110, an input device 112, a display device 114, a printer 116, a warning light 118, a memory device 120, and an audio output unit ( 122).

The input device 112 may be applied to various known devices such as a keyboard, a mouse, and a touch screen.

The display device 114 is controlled by the main controller 110 to display display information. Preferably, the display device 114 has a touch screen.

The printer 116 is controlled by the main control unit 110 to print and output the output target information.

Warning lights 118 may be applied in number depending on the type of fire protection equipment 500 is applied, for example, a fire alarm, disconnection warning light, low water level detection warning light may be applied. Here, the low water level detection warning light warns this by the control of the main control unit 100 when the water level of the tank is detected to be below the set level when the water level sensor for detecting the water level of the tank for storing the firefighters for fire fighting is applied to the fire fighting facility 500. Refers to a warning light installed to

The warning lamp 118 is not provided separately from the display device 114, but may be displayed on the screen displayed through the display device 114.

The memory device 120 stores a system driving program and collected information and is controlled by the main controller 110.

In this case, the system driving program is an application program that is configured to provide a main screen through the display device 114 at the time of execution and to perform a process corresponding to selection of various menus and environment settings provided on the main screen.

The sound output unit 122 outputs various types of sound information such as a fire occurrence guide broadcast, and a conventional amplifier is applied to the sound output unit 122.

The receiver server 100 checks the operation state and abnormality of the fire fighting equipment 500, and stores the operation state information in the storage device 120 when the recording mode is set.

The relay controller 200 is connected to the receiver server 100 through the third communication interface 140.

The third communication interface 140 is preferably configured to perform RS232 communication supporting full duplex communication.

The relay controller 200 and the relay panel 300 are connected through the second communication interface 240.

The second communication interface 240 is constructed to perform RS485 communication. In the illustrated example, eight relay panels 300 are connected to the relay controller 200, but the number of the relay panels 300 may vary depending on the application environment.

Each of the relay boards 300 is connected by a plurality of repeaters 400 and the first communication interface 340.

In the illustrated example, 127 repeaters 400 are connected to each of the relay boards 300.

The first communication interface 340 is constructed to perform RS485 communication.

The fire fighting equipment 500 is connected to the repeater 400 one-to-one.

Fire-fighting equipment 500 includes a variety of well-known electronic control and electrical signals for firefighting, such as fire detectors, gas detectors, sprinkler open / close valves, fire water level detection sensors in firefighting water storage tanks, motors for fire water supply pumps, shutter drivers for smoke shutoff, and the like. A facility capable of outputting can be applied.

On the other hand, the repeater 400 is provided with three rotary switches 411 to 413 to be exposed to the outside of the housing (not shown), as shown in FIG.

 The rotary switches 411 to 413 rotate the movable plate 417 to set any one of the numbers 0 to 9 so as to be spaced apart from each other on the fixed panel 416 by the movable plate 417. The output signal corresponding to the selected number can be output.

For example, the rotary switches 411 to 413 are provided with a plurality of voltage divider resistors such that one terminal of the power source is switched on to correspond to the number selected by the movable plate 417, thereby providing a voltage signal different from 0 to 9. Various known structures, such as those capable of outputting, can be applied.

In the illustrated example, three rotary switches 411 to 413 are applied to set one of three digits in the decimal system for the case where 127 repeaters 400 are applied to one relay panel 300. Reference numeral 411 is for setting a place of work, 412 is for setting a place of 10, and 413 is for setting a place of 100. Therefore, when the user wants to set the repeater 400 to 5, the first rotary switch 411 may be set to 5, and the second and third rotary switches 412 and 143 may be set to 0, respectively. .

The sub control unit 420 converts the decimal value set and output by the rotary switches 411 to 413 into a binary value and sets it as its own address. For example, when the value set by the rotary switches 411 to 413 is set to 5 in the decimal system, the self address is set to "00000101" which is a binary value corresponding to 5 in the case of an 8-bit address system.

The communication module 430 transmits / receives and processes a signal between the relay panel 300 and the fire fighting equipment 500.

Such a receiver system communicates using a packet 610 having a structure as shown in FIG.

Is a field for describing a destination address, 617 is a field for describing an OP code, and 619 is a field for describing data corresponding to the command code. The reference numeral 621 is a field in which a code that can be used to check the validity of the packet 610 is described.

Between the receiver server 100 and the relay panel 300, the receiver server 100 operates as a master and the relay panel 300 operates as a slave.

In addition, the relay panel 300 operates as a master between the relay panel 300 and the relay 400, and the relay 400 operates as a slave.

In such a system, the receiver server 100 periodically polls the relay panel 300 through the relay console control device 200 to collect information on whether there is a communication error and an emergency situation, and the relay panel 300. ) Responds. In addition, relay panel 300 also performs polling to collect information on the presence or absence of communication errors and emergencies in relay 400, and relay panel 400 responds to this. Through this process, it is possible to check the disconnection of the communication line and to check the occurrence of a fire or other emergency situation to be detected.

Preferably, the communication packet 610 applied between the receiver server 100 and the relay panel 300 variably applies the length of the payload description field 619 and the relay panel 300 and the relay 400. The packet 610 applied in between applies a fixed length of the payload description field 619.
