[0013]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a circuit configuration of an embodiment of a disaster prevention system having a simulation function according to the present invention. A. 1. Configuration of Disaster Prevention System (a) Overall Configuration In FIG. 1, each of 1 to 6 is a fire detector, and more specifically, each of 1 and 2 is an on / off type sensor, 3 is a photoelectric analog sensor, Is a thermal analog sensor, and each of 5 and 6 is a photoelectric separation type analog smoke sensor. The on / off type sensors 1 and 2 are connected to the disaster prevention receiver 50 via the repeater 10, and the photoelectric analog sensor 3, the thermal analog sensor 4, and the photoelectric separated analog smoke detector 5, 6 are directly connected to the disaster prevention receiver 50. 20, 2
Each of the devices 1 is a smoke prevention device such as a fire door, a fire damper, and a smoke dumper, and is connected to the disaster prevention receiver 50 via the repeater 11. Reference numeral 30 denotes a district bell, which is connected to the disaster prevention receiver 50 via the repeater 12. Note that these terminal devices are not limited to the illustrated number of installations, but are listed as examples. Therefore, it is needless to say that the number of installations may be more than this.

The disaster prevention receiver 50 is an on / off type sensor 1,
2. Signals are indirectly received between the smoke elimination devices 20 and 21 and the district bell 30 via the repeaters 10 to 12 by, for example, a polling / selecting transmission method.
That is, the disaster prevention receiver 50 inquires each of the repeaters 10 to 12 at predetermined intervals whether or not there is transmission information. Each of the repeaters 10 to 12 receiving this transmits an end code if there is no transmission information, and transmits a signal if there is no transmission information.

On the other hand, a photoelectric analog sensor 3, a thermal analog sensor 4, and a photoelectric separate analog smoke sensor 5,
6, the signal is directly received by the polling / selecting transmission method without interposition of a repeater. That is, the disaster prevention receiver 50 directly inquires each of the photoelectric analog sensor 3, the thermal analog sensor 4, and the photoelectric separated analog smoke detectors 5, 6. Receiving this, the photoelectric analog sensor 3, the thermal analog sensor 4, and the photoelectric separated analog smoke detectors 5, 6
Transmit analog data and the like. In this case, as in the above case, the inquiry about whether or not there is transmission information is performed at predetermined intervals. The disaster prevention receiver 50 outputs signals output from the various sensors 1 to 6 and the repeater 10 to output an abnormal signal such as a fire or a disconnection, a disaster prevention information signal such as analog data, and smoke prevention. By inputting signals output from the devices 20 and 21 and the repeater 10, a disaster prevention information signal such as a start confirmation signal and a disconnection signal is output. The interface 60 is used to input a contact signal from an alarm device such as a security receiver or an emergency broadcast device to the event display device 100.

An event display device 100 includes a control unit 101, a display 102 such as a CRT, a keyboard 103 and a mouse 104, and a printer 105. Two-way communication is performed by a method (for example, transmission according to the RS232C standard). Disaster prevention receiver 50, event display device 10
The two-way communication between 0 uses a polling / selecting transmission system with the disaster prevention receiver 50 as a parent and the event display device 100 as a child. When there is a disaster prevention information signal to be transmitted, the disaster prevention receiver 50 outputs a disaster prevention information signal to the event display device 100 by selecting. Also,
For example, a call for a signal such as a control signal to be transmitted is made every 0.5 seconds, and the event display device 100 receives this call, and when there is no signal to be transmitted, there is no signal to be transmitted. Is output, and when there is a signal to be transmitted, a signal is output. The event display device 100 displays various disaster prevention information signals output from the disaster prevention receiver 50 on the display 102, based on these disaster prevention information signals.
The control signal is output to the disaster prevention receiver 50 as necessary. Further, various disaster prevention information signals output from the disaster prevention receiver 50 are output to the printer 105 and stored in an external storage device 119 (see FIG. 2) described later.

Here, the control signal to be output to the disaster prevention receiver 50 includes, for example, an activation signal for activating a smoke prevention device. This control signal is output by clicking a symbol mark or a character displayed on the display 102 with the mouse 104. For example, when the user clicks the symbol of the smoke evacuator 20 or the smoke evacuator 21 on the floor plan screen showing the plane in the building shown in FIG. 3, a confirmation menu as to whether or not to start is displayed. When selected, a start signal for starting the smoke control device is output. The plan view screen shown in FIG. 3 is displayed on the display 102 by selecting a menu for designating the screen.

When an operation for shifting to the simulation mode is performed as will be described later, the event display device 100 transmits the serial data to the simulation unit 200 in the same manner as the two-way communication performed with the disaster prevention receiver 50. To perform two-way communication. In the bidirectional communication between the event display device 100 and the simulation unit 200, a polling / selecting transmission system is performed using the simulation unit 200 as a parent and the event display device 100 as a child. The simulation unit 200 outputs to the event display device by selecting when there are signals such as various pseudo disaster prevention information signals to be transmitted. If there is no signal to be transmitted, a call is made every 0.5 seconds, for example, to check whether there is a signal such as a control signal to be transmitted to the event display device 100 by polling. hand,
When there is no signal to be transmitted, an end command indicating that there is no signal to be transmitted is output, and when there is a signal to be transmitted, a signal is output. The event display device 100
By inputting various pseudo disaster prevention information signals output from the simulation unit 200, display based on these disaster prevention information signals is performed on the display 102, and a control signal is output to the simulation unit 200 as necessary.

Further, various disaster prevention information signals output from the simulation unit 200 are output to the printer 105 and stored in an external storage device 119 described later.
The control signal output to the simulation unit 200 includes, for example, an activation signal for activating a smoke prevention device, and is output by clicking a symbol mark or a character displayed on the display 102 with the mouse 104. For example, on a plan view screen showing a plane of a certain floor in a building shown in FIG.
When the user clicks on the symbol 1 and selects “start” in the confirmation menu displayed at that time, a start signal for starting the smoke prevention device 20 or the smoke prevention device 21 is output.
In this case, the start signal is output from the simulation unit 200.
Therefore, the smoke-control device 20 or the smoke-control device 21 does not actually start.

When the event display device 100 determines that a failure has occurred in the communication with the disaster prevention receiver 50 during the simulation, the event display device 100 shifts from the simulation mode to the normal monitoring mode. Further, when it is determined that a failure has occurred in the communication with the simulation unit 200, the mode shifts from the simulation mode to the normal monitoring mode as described above. The determination of the occurrence of the communication failure is performed when normal communication cannot be performed for a predetermined time (for example, 10 seconds). In the case where normal communication cannot be established,
This is the case where there is no call by polling, or the case where a signal is transmitted by selecting but the content of the signal is a content that cannot be in a normal communication state.

Further, the event display device 100 displays a communication failure on the display 102 when it is determined that a communication failure has occurred as described above and the mode has shifted from the simulation mode to the normal monitoring mode. In this case, when it is determined that there is a communication failure with the disaster prevention receiver 50, for example, a message “There is a communication failure with the disaster prevention receiver 50” is displayed, and the communication failure with the simulation unit 200 is displayed. If it is determined that there is, for example, a message that "there is a communication failure with the simulation unit 200" is displayed.

In FIG. 1, a keyboard 103 is used for inputting various data, and a mouse 104 is used for selecting a symbol mark or a character displayed on the display 102 as described above. In addition to the mouse 104, a pointing input device such as a light pen, a tablet, or a trackball can be used. On the display 102, a menu screen shown in FIG. 5 is displayed as an initial screen. In this menu screen, "List" and "
Selecting each menu representing each floor excluding "Simulation" displays a plan view of each floor of the building, for example, as shown in Fig. 3. Also, selecting "List" displays an event that occurred, for example, as shown in Fig. 4. A list of records showing the contents and the date and time of occurrence is displayed, and if "simulation" is selected, the mode shifts to the simulation mode.

In FIG. 1, a simulation unit 200 is provided with abnormal information such as a simulated fire, etc.

The input of various signals such as control signals output by manual operation input or automatic interlocking control in the event display device 100, and the time management of these input / output signals can be performed by controlling the time of fire or the like when an abnormality such as an actual fire occurs. A simulation is performed at the time of an abnormality such as a fire in accordance with a simulation pattern set assuming the location of occurrence of the abnormality, the scale, the state of expansion, the handling of an operator such as a disaster prevention manager, and the like. And outputs a disaster prevention information signal equivalent to the received disaster prevention information signal. In this case, the simulation pattern includes an operation input by an operator such as a disaster prevention manager or an input by an automatic interlocking control output, and an occurrence position of an abnormality such as a fire due to management of a time required for the input.

B. Operation of Disaster Prevention System In the above configuration, the operation will be described with reference to a flowchart. In this operation description, first,
The operation of the event display device 100 will be described, and then the operation of the event display device 100 and the operation of the simulation unit 200 based on this pattern will be described using an example of a simulation pattern. An outline of an example of the simulation pattern will be described below.

(A) Operation of the event display device 100 FIG. 6 is a flowchart showing the operation of the event display device 100. (A) Normal monitoring processing First, normal monitoring processing is performed in step S10. That is, input of various disaster prevention information signals output from the disaster prevention receiver 50, output of control signals to the disaster prevention receiver 50, display control of the display 102, and the like are performed.

(B) Transmission of Simulation Start Command During normal monitoring processing, step S12 is executed.
, That is, whether or not an operation for starting a simulation has been performed by the operator on the event display device 100. If it is determined that there is a simulation start input, the process proceeds to step S14, and the simulation unit A start command for starting the simulation is transmitted to 200.
In this case, the start command includes a pattern signal specifying a simulation pattern.

(C) Setting the simulation mode After transmitting the simulation start command, it is determined whether or not there is a simulation mode setting input in step S16. This determination is repeated until there is a simulation mode setting input. If it is determined that there is a simulation mode setting input, step S1 is performed.
Proceed to 8 to set the simulation mode. That is, the simulation mode setting signal is received from the simulation unit 200 to set the simulation mode. In the setting of the simulation mode, a display indicating that the simulation is being performed, a stop of a control signal to the disaster prevention receiver 50, a setting of an inoperable switch, and the like are performed. The setting of the inoperable switch is
This is a setting that disables the operation input of switches that must not be operated by the operator such as the disaster prevention manager during the simulation.

(D) Input processing After setting the simulation mode, it is determined in step S20 whether or not there is an input signal from the simulation unit 200. In this case, the simulation unit 200 outputs a disaster prevention information signal such as an abnormal signal such as a simulated fire or a disconnection, a disaster prevention information signal such as analog data, a startup confirmation signal, or a disconnection signal. If it is determined that the disaster prevention information signal has been input from the simulation unit 200, the process proceeds to step S22, where the supplied disaster prevention information signal is analyzed.

In step S24, display or output is performed based on the analysis result. For example, if the input disaster prevention information signal is a fire signal, the fire sensor that has output the fire signal is specified, and the symbol mark on the display 102 corresponding to the fire sensor blinks. For example, if the on / off type sensor 2 attached to the kitchen shown in FIG. 3 issues an alarm, the symbol mark corresponding to the kitchen dividing line on the display 102 flashes in red, and the issued on / off is emitted. The symbol mark corresponding to the pattern sensor 2 blinks in red. In addition, when a signal during start-up of a smoke prevention device or the like is input, the symbol mark on the display 102 corresponding to the corresponding smoke prevention device blinks in blue, for example. After that, when the start confirmation signal is input, the light is turned on in blue.

After performing the display or output process in step S24, it is determined in step S26 whether the simulation end condition is satisfied. That is, it is determined whether any of the following conditions is satisfied. An abnormal signal such as a fire signal was output from the disaster prevention receiver 50. An emergency contact signal was output from the disaster prevention receiver and the emergency broadcast device. Communication with the disaster prevention receiver 50 could not be performed normally for a predetermined time (for example, 10 seconds), and it was determined that a failure occurred.
An operation to end the simulation was performed. The simulation unit 200 has output a simulation end signal. Simulation unit 20
The communication with 0 cannot be performed normally for a predetermined time (for example, 10 seconds), and it is determined that a failure has occurred. Any one of these ~
If at least one is satisfied, the process proceeds from step S26 to step S28, and if neither is satisfied, the process returns to step S20.
When the process returns to step S20 on the assumption that the simulation end condition is not satisfied, the simulation unit 2
It is determined whether there is an input signal from 00.

In this determination, when it is determined that there is no input signal from the simulation unit 200, the process proceeds to step S30 to determine whether there is an input signal from the disaster prevention receiver 50. In this determination, when it is determined that there is an input signal from the disaster prevention receiver 50, step S22 is performed.
To analyze the input signal. In this case, for example, if the disaster prevention information signal input from the disaster prevention receiver 50 is a fire signal, the simulation end condition is determined in step S26, and the process proceeds to step S28.

If it is determined in step S30 that there is no input signal from the disaster prevention receiver 50, step S3
Proceed to 2 to determine whether or not there is an operation input. That is, it is determined whether or not an operation to activate the smoke prevention device or change the display is performed. If it is determined in this determination that there is an operation input, the process proceeds to step S22, where the operation input is analyzed. If the input is a control signal, the control signal is output or the display is changed in step S24. For example, if the operation input is to activate the smoke prevention device 20, a smoke prevention activation signal is output. On the other hand, if it is determined that there is no operation input, the process proceeds to step S26.

As described above, the simulation unit 2
When there is an input signal from 00, when there is an input signal from the disaster prevention receiver 50, when there is an operation input on the event display device 100, the contents are analyzed, and a predetermined display is performed according to the result. And outputs a control signal. Note that among the signals output from the disaster prevention receiver 50, there is a signal that does not indicate an abnormality. If this signal is output, the event display device 100 displays the symbol corresponding to the signal as it is even during the simulation. The mark is displayed on the display 102.

(E) Simulation end processing In the judgment of step S26, when it is judged that the simulation end condition is satisfied, and the process proceeds to step S28, an end command for ending the simulation is transmitted to the simulation unit 200. After transmitting the end command, the simulation mode is ended in step S34, and processing for shifting to the normal monitoring mode is performed. After this process, the process proceeds to step S36, where it is determined whether the end of the simulation is an abnormal end. For example, in the simulation end condition described above,
In the case of,, it is determined that the operation is terminated due to an abnormality, and the process proceeds to step S38. On the other hand, if it is determined that the end of the simulation is not due to an abnormality, the process returns to step S10 without performing any processing. When it is determined that the end of the simulation is due to an abnormality and the process proceeds to step S38, the content of the abnormality is displayed on the display 102. For example, if there is a communication failure with the disaster prevention receiver 50, for example, a message that "there is a communication failure with the disaster prevention receiver 50" is displayed. If a communication failure has occurred with the simulation unit 200, for example, a message that "there is a communication failure with the simulation unit 200" is displayed. After the display indicating this abnormality is performed, the process returns to step S10.

(B) Operation of the simulation unit 200 FIGS. 7 and 8 are flowcharts showing the operation of the simulation unit 200 according to an example of a simulation pattern. (B) Contents of the simulation pattern In this simulation pattern, first, the on / off type sensor 2 attached to the kitchen shown in FIG. Then, it is determined whether or not the operator has performed an operation for activating the smoke prevention device 20 closest to the on / off type sensor 2 within 180 seconds in response to the fire signal. If it is determined that the smoke control device 20 was operated within that time, the simulation was terminated because the fire spread was prevented, and if it was determined that the smoke control device 20 was not operated, the spread of the fire was not prevented. As a result, each fire sensor (on / off sensor 1, photoelectric analog sensor 3,...) Sequentially issues an alarm in the order of proximity to the on / off sensor 2. This assumes a situation in which a fire signal indicating that the alarm has been issued is output.

(B) Simulation mode setting processing First, in step S50, it is determined whether or not there is a simulation start command. If it is determined in this determination that there is no simulation start command, the process of step S50 is repeated. If it is determined that there is a simulation start command, the process proceeds to step S52, where the simulation pattern corresponding to the pattern signal included in the simulation start command is stored in the external storage device. 217
And read it into the RAM 213. (C) Output processing of a pseudo fire signal Then, the process proceeds to step S54, and the event display device 10
A simulation mode setting signal for setting the simulation mode to 0 is output. Next, step S56
And outputs a fire signal to the event display device 100 indicating that the on / off type sensor 2 attached to the kitchen has issued an alert.

(D) Output processing of the smoke prevention start signal and the smoke prevention start signal Next, a 180-second timer is cleared and started in step S58, and it is determined in step S60 whether 180 seconds have elapsed. Do. If it is determined in this determination that 180 seconds have not elapsed, the process proceeds to step S62,
It is determined whether or not there is a smoke emission start signal. In other words, it is determined whether or not the operator has taken appropriate action in this state within 180 seconds after the on / off type sensor 2 has issued the alarm. In this case, if the operator performs an operation of activating the smoke prevention device 20 on the event display device 100, the event display device 100 outputs a smoke prevention smoke activation signal.

If it is determined in step S62 that the smoke prevention start signal has not been output from the event display device 100, the process returns to step S60. If it is determined that the smoke prevention start signal has been output, the process proceeds to step S64. In this case, if the operation of activating the smoke evacuating apparatus 20 is performed within 180 seconds after the on / off type sensor 2 issues an alarm, and the process proceeds to step S64, the event display apparatus 100 outputs a smoke activating smoke activating signal. Is output. Then, at step S66, 2
After waiting for two seconds, in step S68, a smoke-prevention-smoke-start-up confirmation signal notifying that the smoke-prevention device 20 has been activated is output to the event display device 100. After outputting the smoke prevention start-up confirmation signal, the process proceeds to step Sn (n is a step number) described later, and waits for 5 seconds. Then, after waiting for 5 seconds, a simulation end signal is output to the event display device 100 in step Sn + 1, and the process ends.

(E) Output processing of a simulated fire signal corresponding to the fire detectors after the first fired fire detector On the other hand, within 180 seconds after the on / off type detector 2 is fired, the operator If the user does not perform the operation of activating the smoke prevention device 20, the process proceeds from step S60 to step S70, and it is assumed that the on / off type sensor 1 closest to the on / off type sensor 2 has further issued the alarm. Then, a fire signal indicating that the on / off type sensor 1 has issued an alarm is output to the event display device 100. Then, after waiting for 5 seconds in step S72, assuming that the photoelectric analog sensor 3 next to the on / off type sensor 2 has issued a warning in step S74,
A fire signal indicating that the photoelectric analog sensor 3 has issued an alarm is output to the event display device 100. After that, every time the apparatus waits for 5 seconds, it is assumed that the fire detectors have issued alarms in the order closer to the on / off type sensor 2, and outputs a fire signal indicating that each fire alarm has been issued to the event display device 100. As described above, if the operation for activating the smoke elimination device 20 is not performed within 180 seconds after the first fire detection is issued, a process indicating that the spread of fire spreads is performed. Then, after a predetermined number of fire detectors are issued, the process proceeds to step Sn + 1, where a simulation end signal is output to the event display device 100, and the process ends.

(C) Operation of the Event Display Apparatus 100 Based on an Example of a Simulation Pattern When a fire signal indicating that the on / off type sensor 2 has issued an alarm is supplied from the simulation unit 200, the fire signal is analyzed. The symbol mark corresponding to the kitchen lane mark on the display 102 corresponding to the on / off type sensor 2 blinks in red, and the symbol mark corresponding to the issued on / off type sensor 2 blinks in red. Let it. Then, when it is determined that there is an operation input for starting the smoke prevention device, after analyzing the input, a start signal for starting the corresponding smoke prevention device is output. After outputting this start signal, the simulation unit 20
When the smoke prevention device 20 is supplied with the smoke prevention device starting signal from 0, the symbol mark corresponding to the smoke prevention device 20 blinks in blue on the display 102, and thereafter, the start confirmation signal is supplied. And analyze the input and switch to blue lighting. Thereafter, when a simulation end signal is supplied from the simulation unit 200, the simulation is ended and the mode shifts to a normal monitoring mode.

On the other hand, when an operation input for activating the smoke control device is not performed within 180 seconds, a fire signal indicating that the on / off type sensor 1 has issued an alarm is supplied from the simulation unit 200. After analyzing the fire signal, the symbol mark corresponding to the dividing line of the cafeteria on the display 102 corresponding to the on / off type sensor 1 blinks in red, and the symbol corresponding to the on / off type sensor 1 which has issued the alarm is displayed. Flashes in red. Next, when a fire signal indicating that the photoelectric analog sensor 3 has issued an alarm is supplied from the simulation unit 200, the fire signal is analyzed, and then the dining room on the display 102 corresponding to the photoelectric analog sensor 3 is analyzed. The symbol mark corresponding to the issued photoelectric analog sensor 3 is blinked in red. Thereafter, every time a simulated fire signal is supplied from the simulation unit 200, the symbol mark corresponding to the division line on the display 102 corresponding to the relevant fire sensor flashes in red, and the fire detector The symbol mark corresponding to blinks red.

As described above, in this embodiment, during the simulation, if communication with the disaster prevention receiver 50 cannot be performed normally for a predetermined time and it is determined that a failure has occurred, communication with the simulation unit 20 is performed. If it is determined that a failure has not occurred during the predetermined period of time and a failure has been determined, the mode immediately shifts from the simulation mode to the normal monitoring mode, and a message indicating a communication failure is displayed on the display 102. Therefore, the operator such as the disaster prevention manager can confirm that the operation has shifted to the normal monitoring mode and the communication failure, so that even if an abnormality such as a fire actually occurs, the operator can deal with it without delay.

The present invention is not limited to the above embodiment, but various embodiments can be made within the scope of the present invention. Specifically, it may be implemented as follows. (A) In the above embodiment, when a communication failure occurs, a message notifying the communication failure is displayed on the display 102. However, the event display device 100 is provided with a sounding means for outputting a voice message or outputting a sound. The sounding means may be provided so as to operate when a communication failure occurs, or may be combined with the display of a message. (B) In the above embodiment, all functions including the display function are performed by the event display device 100. However, all functions are provided in the disaster prevention receiver 50, and all of the functions are performed by the disaster prevention receiver 50. Alternatively, a part may be performed. Thus, a simulation can be performed between the disaster prevention receiver 50 and the simulation unit 200. This example will be described below.

(C) In the above embodiment, the event display device 100 and the simulation unit 200 are provided separately.
Although the simulation is performed between the event display device 100 and the simulation unit 200 via the communication line, other methods shown in FIG. 9 may be used. That is, in the method shown in (1), the event display device 100 and the simulation unit 200 are separated from each other, and the simulation unit 200 is arranged between the disaster prevention receiver 50 and the event display device 100, and is connected via a communication line. The simulation is performed with the event display device 100. In this case, the simulation unit 200 includes the switching unit 30
The common contact c is connected to the event display device 100, the fixed contact a is connected to the disaster prevention receiver 50, and the fixed contact b is connected to the control unit 301. When performing a simulation, the common contact c of the switching means 300 is connected to the fixed contact b. Thus, the simulation is performed according to the simulation pattern stored in the storage unit 302 of the simulation unit 200.

The control means 301 constantly monitors the disaster prevention information signal output from the disaster prevention receiver 50. When an abnormal signal such as a fire is output from the disaster prevention receiver 50 during the simulation, the switching control of the switching means 300 is performed. And the common contact c is connected to the fixed contact a. In this method, during the simulation mode, the common contact c of the switching means 300 is connected to the fixed contact b, so that the control signal output from the event display device 100 is
Is never entered. Therefore, it is not necessary to provide the event display device 100 with a function of preventing the control signal from going to the disaster prevention receiver 50 during the simulation.

If the communication with the disaster prevention receiver 50 cannot be performed normally for a predetermined time during the simulation, the control means 301 determines that a communication failure has occurred, immediately stops the simulation, and notifies the communication failure. The communication failure signal is output to the event display device 100. After the communication failure is notified, the switching control of the switching means 300 is performed, and the common contact c is connected to the fixed contact a.

On the other hand, when the event display device 100 receives a communication failure signal indicating a communication failure from the control means 301, it determines that there is a communication failure between the disaster prevention receiver 50 and the simulation unit 200 on the display 102, Immediately shift from the simulation mode to the normal monitoring mode, for example, "There is a communication failure between the disaster prevention receiver 50 and the simulation unit."
Is displayed. If the communication with the simulation unit cannot be normally performed for a predetermined time during the simulation, the event display device 100 immediately shifts from the simulation mode to the normal monitoring mode. There is a communication failure between the devices. "

The method (2) uses the event display device 100
And a simulation unit 200 built therein. By doing so, usability is improved, a communication line connecting the simulation unit 200 and the event display device 100 is not required, and components common to the event display device 100 can be omitted. Therefore, cost can be reduced. As the built-in system, a system in which the simulation unit 200 is fixed to the event display device 100 and a system in which the simulation unit 200 is detachably mounted are conceivable.

In this system, the event display device 1
There is no need to monitor the state of communication between 00 and the simulation unit 200. However, the simulation unit 200 and the event display device 10 are connected using a connector.
In the case where 0 is connected, a contact failure or the like may occur. In such a case, the communication state between the event display device 100 and the simulation unit 200 may be monitored.

In the method (3), the simulation unit 200 is built in the disaster prevention receiver 50. By doing so, the usability is improved similarly to the method (2), and a communication line connecting the simulation unit 200 and the disaster prevention receiver 50 is not required. Since common parts can be omitted, cost can be reduced. Further, in this method, it is not necessary to monitor the communication state between the disaster prevention receiver 50 and the simulation unit 200. However, when the simulation unit 200 and the disaster prevention receiver 50 are connected to each other by using the connector as described above, there is a possibility that a contact failure or the like may occur. In such a case, the connection between the disaster prevention receiver 50 and the simulation unit 200 may be made. The state of communication between them may be monitored.

In the method (4), the disaster prevention receiver 50 and the simulation unit 200 are separated from each other, and the disaster prevention receiver 50 and the simulation unit 20 are connected via a communication line.
The simulation is performed between 0 and 0. In this method, when communication with the simulation unit 200 cannot be performed normally for a predetermined time during the simulation, the disaster prevention receiver 50 determines that a communication failure has occurred and immediately shifts from the simulation mode to the normal monitoring mode. For example, there is a control unit that displays a message that “a communication failure has occurred with the simulation unit 200”. (3),
In the case of the embodiment of (4), the disaster prevention receiver 50 immediately starts the communication when a failure occurs in the communication with the terminal devices such as the fire detector, the smoke prevention device, and the repeater during the simulation. In addition, the control unit shifts from the simulation mode to the normal monitoring mode and has a control means for displaying a message such as "There is a communication failure. Photoelectric analog sensor 3" on the display.

(D) In addition to incorporating the simulation unit 200 in the disaster prevention receiver 50 or the event display device 100, the function of the simulation unit 200 may be provided as software. In this case, the cost can be reduced because the software can be added. (E) In the above embodiment, when the fire detector gives an alarm,
The manual operation of the smoke prevention equipment near the fire detector was started by the operation of the operator such as the disaster prevention manager, but the smoke prevention equipment corresponding to the fire detector that issued the alarm is started. A matrix table may be provided, and an automatic interlocking control for automatically activating a corresponding smoke prevention device when a fire detector issues an alarm may be used.

(F) In the above embodiment, the simulation is started by inputting a command by operating the mouse 104 on the event display device 100. However, the simulation may also be started by the disaster prevention receiver 50. Further, a simulation start switch and a simulation selection switch are provided on the simulation unit 200 side, and by operating these switches, a simulation mode setting input signal is output from the simulation unit 200, and the simulation may be started by this signal. . In this case, the event display device 1
00 goes to the simulation mode by taking in the simulation mode setting input signal output from the simulation unit 200. (G) In the above embodiment, the floppy disk or the memory card is used for storing the simulation pattern.
k), a ROM, an EEPROM, a hard disk, or the like may be used.

(H) The simulation pattern of the above embodiment is such that if the smoke prevention device closest to the fire detector is operated within 180 seconds from the first fire alarm, the fire spreads. It was a simple example in which if the smoke prevention equipment could not be activated within 180 seconds, the spread of fire spread and fire detectors fired one after another.
In addition, various patterns are conceivable depending on the structure of the building, the contents of the disaster prevention equipment, or the customer's request. Therefore, by creating simulation patterns of various contents, operators, such as disaster prevention managers, can gain experience according to various situations. You can learn through experience how you can minimize it or take it in a safer direction. In addition, operators such as disaster prevention managers can learn through their simulated experiences their responsibilities in the event of a fire and the significance of not taking proper actions when a fire occurs, leading to an increase in disaster prevention awareness.

(I) The simulation pattern in the above embodiment is for a fire, but may be a simulation pattern for crime prevention or the like. (J) In the above embodiment, the terminal equipment connected to the disaster prevention receiver is used for fire alarm equipment, but a security sensor used for security equipment, an automatic alarm valve used for fire extinguishing equipment, etc. Any type may be used as long as it is used for a disaster prevention system. (K) In the above embodiment, the communication between the devices uses the polling / selecting transmission system. However, it goes without saying that the same applies to the case where another transmission system is used.

An operator such as a disaster prevention manager can confirm that the system has shifted to the normal monitoring mode and that a communication failure has occurred. However, it is possible to deal with the situation early and accurately.
