Description

The present invention relates to an alarm system .

  Conventionally, in an alarm system, a plurality of fire detectors are connected to a dedicated line drawn from a receiver. When the fire detector detects a fire, it transmits a fire detection signal to the receiver. The receiver issues a fire alarm by ringing the district acoustic device based on the fire detection signal supplied from the fire detector.

  In recent years, with the increase in the number of elderly people and the progress of social participation by people with disabilities, people in buildings where the alarm system is installed are expected to include people with hearing impairments, including those with impaired hearing. The However, hearing-impaired persons may not be able to respond quickly to disasters because they cannot hear an alarm sound when a disaster occurs.

  In order to solve the above problem, an alarm system has been proposed that uses a light alarm device such as a flashlight with high visibility together with an acoustic device (for example, see Patent Document 1) to notify the occurrence of a disaster. This alarm system provides an alarm (hereinafter referred to as “light alarm”) when a light alarm device emits flash light in addition to an alarm sound in the event of a disaster such as a fire. Can be performed.

  By the way, at the time of construction or periodic inspection of the alarm system building, the operator needs to check the operation of the sound device and the light alarm device. Therefore, the operator supplies power from the receiver to the sound device and the light alarm device, which are alarm devices, and confirms the sounding of the sound device and the light alarm of the light alarm device.

The first button group 31B includes buttons 31B-1 to 31B-n.

The first button group 31 </ b> B is a switch provided for selecting the district sound line 6. Specifically, each of the buttons 31B-1 to 31B-n is provided corresponding to each of the district sound lines 6-1 to 6-n. For example, when the button 31B-1 is pressed by the operator, the operation unit 31 outputs the line number of the district acoustic line 6-1 associated with the button 31B-1 to the control unit 32. This means that the operator has selected the district acoustic line 6-1 (or terminal EA _2n ). Further, when the button 31B-2 is pressed by the operator, the operation unit 31 outputs the line number of the district acoustic line 6-2 associated with the button 31B-2 to the control unit 32. This means that the operator has selected the district audio line 6-2 (or terminal EA _{n + 2} ). When the button 31B-n is pressed by the operator, the operation unit 31 outputs the line number of the district acoustic line 6-n associated with the button 31B-n to the control unit 32. This means that the operator has selected the district acoustic line 6-n (or terminal EA _{n + 1} ).

The second button group 31E includes buttons 31E-1 to 31E-n.
The second button group 31E is a switch provided for selecting the optical alarm line 9. Specifically, each of the buttons 31E-1 to 31E-n is provided corresponding to each of the optical alarm lines 9-1 to 9-n. For example, when the button 31E-1 is pressed by the operator, the operation unit 31 outputs the line number of the optical alarm line 9-1 associated with the button 31E-1 to the control unit 32. This means that the operator has selected the optical alarm line 9-1 (or terminal EA ₁ ). When the button 31E-2 is pressed by the operator, the operation unit 31 outputs the line number of the light alarm line 9-2 associated with the button 31E-2 to the control unit 32. This means that the operator has selected the optical alarm line 9-2 (or terminal EA ₂ ). When the button 31E-n is pressed by the operator, the operation unit 31 outputs the line number of the light alarm line 9-n associated with the button 31E-n to the control unit 32. This means that the operator has selected the optical alarm line 9-n (or terminal EA _n ).

  FIG. 4 is a diagram illustrating a second configuration example of the selection switch 312 in the present embodiment. As a second configuration example of the selection switch 312 of this embodiment, the selection switch 312 includes a display unit 320, a switch unit 321, and a confirmation switch 322.

  The display unit 320 displays information (for example, a line number) indicating the line selected by the switch unit 321. For example, the display unit 320 is a display using a plurality of 7-segment LEDs.

  The switch unit 321 is a switch operated by an operator when selecting a test line from the district acoustic lines 6-1 to 6-n and the optical alarm lines 9-1 to 9-n. When the switch unit 321 is operated, information displayed on the display unit 320 is changed. That is, the selected line is changed and a new line is selected. Accordingly, the operator operates the switch unit 321 while confirming the information displayed on the display unit 320, thereby allowing the workers to operate the district acoustic lines 6-1 to 6-n and the light alarm lines 9-1 to 9-n. The test line can be selected. For example, the switch unit 321 may include an up key and a down key. The switch unit 321 may be a cross key.

  The confirmation switch 322 is a switch for confirming that the line indicated by the information displayed on the display unit 320 has been selected. In other words, the confirmation switch 322 is a switch for confirming that the line selected by the switch unit 321 is a test line. When the confirmation switch 322 is operated, the operation unit 31 outputs the line number of the line selected by the switch unit 321 to the control unit 32. As described above, the line selected by the switch unit 321 is a line indicated by the information displayed on the display unit 320.

  Returning to FIG. 2, the execution switch 313 is a switch operated by the operator when confirming the operation of the district sound device 5 or the light alarm device 10 connected to the line determined by the confirmation switch 322 as the test line. . When the execution switch 313 is operated, the operation unit 31 outputs an execution signal indicating that the execution switch 313 has been operated to the control unit 32. Thereby, the district sound device 5 or the light alarm device 10 connected to the line determined as the test line by the confirmation switch 322 is operated in a pseudo manner (hereinafter referred to as “pseudo operation”).

The control unit 32 selects a specific terminal from the terminals EA _1, EA _{2 to} EA _2n based on the line information supplied from the operation unit 31. That is, the control unit 32 selects a terminal connected to the line indicated by the line information supplied from the operation unit 31 from the terminals EA _1, EA _{2 to} EA _2n . Then, the control unit 32 supplies power from the selected terminal. Hereinafter, an embodiment of a method of selecting a specific terminal among the terminal _{EA 1, EA} 2 _{~EA 2n} of the control unit 32 in this embodiment.

  When acquiring the line number supplied from the operation unit 31, the control unit 32 sets the state number of the management table associated with the acquired line number to the first value. Further, the control unit 32 sets the status number of the management table associated with the line number other than the line number acquired from the operation unit 31 to the second value. The first value is set in advance, and is “1”, for example. The second value is set in advance and is, for example, “0”. The management table is stored in advance in the storage unit 33. Below, an example of the management table in this embodiment is demonstrated. FIG. 5 is a diagram illustrating an example of a management table in the present embodiment.

As shown in FIG. 5, in the management table, terminal numbers and state numbers are associated with each other. In the present embodiment, the terminal numbers are the numbers of the terminals EA ₁ and EA _{2 to} E _2n . That is, in the management table, the terminal numbers connected to the district sound lines 6-1 to 6-n and the optical alarm lines 9-1 to 9-n are associated with the state numbers. The status number is a number indicating a terminal corresponding to the line selected as the test line. For example, when the district acoustic line 6-2 is selected as the test line by the selection switch 312, the state number corresponding to the terminal number EA _{n + 2} is set to “1”. Therefore, the line connected to the terminal EA whose terminal number is not set to “1”, that is, whose state number is set to “0” is not a test line.

When acquiring the execution signal supplied from the operation unit 31, the control unit 32 reads the terminal number corresponding to the state number that is the first value from the management table. The control unit 32 supplies power to the terminal having the read terminal number. For example, as illustrated in FIG. 5, when the first value is “1”, the control unit 32 reads the terminal number EA _{n + 2} from the management table. And the control part 32 rings the district acoustic apparatus 5 connected to the district acoustic line 6-2 used as a test line by supplying power from the terminal of the read terminal number EA _{n + 2} . Thereby, the control part 32 can perform the pseudo | simulation operation | movement of the district sound apparatus 5 or the optical alarm device 10 connected to the line | wire selected as a test line.

  Hereinafter, the operation in the inspection mode of the control unit 32 of the present embodiment will be described with reference to FIG. FIG. 6 is a diagram for explaining the processing flow of the inspection mode of the control unit 32 in the present embodiment.

  When the simulated operation of the district sound device 5 or the light alarm device 10 is performed, the operator operates the inspection transition switch 311. When the inspection transition switch 311 is operated by the operator, the control unit 32 is supplied with a control signal from the operation unit 31 (step S101). Thereby, the receiver 30 shifts to the inspection mode.

  The operator operates the selection switch 312 to select a line as a test line from the district acoustic line 6 and the light alarm line 9. When the selection switch 312 is operated by the operator, the control unit 32 is supplied with a line number indicating the line selected as the test line from the operation unit 31 (step S102).

  When acquiring the line number supplied from the operation unit 31, the control unit 32 updates the state number of the management table associated with the acquired line number to the first value. Further, the control unit 32 updates the state number of the management table associated with the line number other than the line number acquired from the operation unit 31 to the second value (step S103).

  The control unit 32 determines whether or not the execution signal supplied from the operation unit 31 has been acquired (step S104). The operator operates the execution switch 313 when performing the simulated operation of the district sound device 5 or the light alarm device 10 connected to the line selected as the test line. The operation unit 31 supplies an execution signal to the control unit 32 when the execution switch 313 is operated by the operator. When acquiring the execution signal supplied from the operation unit 31, the control unit 32 proceeds to the process of step S <b> 105 and executes the pseudo operation of the alarm device 2. On the other hand, the control unit 32 does not execute the pseudo operation of the alarm device 2 when the execution signal supplied from the operation unit 31 is not acquired.

  When acquiring the execution signal supplied from the operation unit 31, the control unit 32 reads the terminal number corresponding to the state number that is the first value from the management table (step S105).

  The control unit 32 supplies power from the terminal with the read terminal number (step S106). Thereby, the control part 32 can operate only the district sound apparatus 5 or the optical alarm device 10 connected to the line selected as the test line. That is, the operator can confirm the operation of some of the district sound devices 5 or the light alarm devices 10.

As described above, the receiver 30 of the present embodiment is connected to a plurality of alarm devices 2 via a plurality of lines (district acoustic lines 6-1 to 6-n and optical alarm lines 9-1 to 9-n). Has been. The receiver 30 includes a plurality of terminals (terminals EA ₁ , EA _{2 to} EA _2n ), an operation unit 31, and a control unit 32. A line is connected to each of the plurality of terminals on a one-to-one basis. When the operator selects a test line from a plurality of lines, the operation unit 31 outputs line information indicating the line selected as the test line. The control unit 32 selects the terminal to which the line selected as the test line is connected based on the line information, and operates the alarm device 2 connected to the test line by supplying power from the selected terminal. That is, since the receiver 30 can supply power for each line, only a specific alarm device 2 (for example, the district sound device 5 or the light alarm device 10) can be operated at the time of inspection. That is, since the receiver 30 can operate only a specific alarm device 2 when performing a pseudo operation for testing the alarm device 2, all the alarm devices 2 can be operated during the pseudo operation of the alarm device 2. Can be prevented from operating and causing trouble to the surroundings.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above-described embodiment, and includes design and the like within the scope not departing from the gist of the present invention.

  In the above-described embodiment, the case where the receiver 30 has a function of supplying power to each of the light alarm devices 10 has been described. However, the present invention is not limited to this. For example, the receiver 30 may further include a function of synchronizing the light emission timings of the light alarm devices 10 installed on each floor. Here, the synchronization means that the deviation of the light emission timing from each of the light alarm devices 10 is within a predetermined time, and the light emission time has an overlap portion longer than the predetermined time.

  Moreover, in the above-mentioned embodiment, although the case where the receiver 30 was provided with the function which supplies a power supply to each of the light alarm apparatus 10 was demonstrated, it is not limited to this. For example, a light control device having a function of supplying power to each of the light alarm devices 10 may be provided between the receiver 30 and the light alarm device 10. This is because a large amount of power is required when simultaneously lighting the plurality of light alarm devices 10. Moreover, you may further provide the function which synchronizes each light emission timing of the light alarm apparatus 10 with a light control apparatus.

  In the embodiment described above, the control unit 32 may select a test line using the key matrix method when the selection switch 312 has the configuration shown in FIG.

  You may make it implement | achieve the control part 32 in embodiment mentioned above with a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. Further, the program may be a program for realizing a part of the above-described functions, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. You may implement | achieve using programmable logic devices, such as FPGA (Field Programmable Gate Array).
