Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire alarm system provided with a plurality of sensors for detecting an abnormality related to a fire and a receiver for monitoring the fire.

[0002]

2. Description of the Related Art A fire alarm system generally includes a plurality of detectors (fire detectors, gas detectors, etc.) for detecting abnormalities related to a fire, and a receiver for monitoring a fire. Such a fire alarm system generally includes a plurality of sensors and transmitters, a district bell and an acoustic device, and smoke emission control via a trunk or a relay connected to the trunk, which extends from the receiver. It is configured by connecting devices and the like. A plurality of devices connected to these receivers are installed over a plurality of districts. The receiver monitors signals from the sensor and the transmitter, and when a signal indicating an abnormality such as a fire alarm is output from the sensor or the transmitter, a process corresponding to the abnormality is performed by the receiver. It is. For example, when a fire signal is output from a certain sensor, an indicator light indicating the occurrence of a fire is turned on, and a display and sound output of a district number indicating a corresponding district where a fire report has been issued are performed in the receiver. An alarm is output by linking a district bell or a sound device connected to the receiver, or a smoke elimination device, a fire hydrant, or the like corresponding to the sensor that issued the alarm is linked.

[0003] The type and arrangement of a plurality of devices (sensors and transmitters, district bells and sound devices, smoke elimination devices, and the like) connected to the receiver depend on the building (or customer) in which the fire alarm system is installed. Everything is different. That is, the type and arrangement of the devices connected to the receiver differ between the fire alarm system corresponding to the customer A and the fire alarm system corresponding to the customer B even if the fire alarm system is of the same type. . For this reason, conventional general fire alarm systems use linked data that indicates the interlocking relationship between devices that detect abnormalities, such as detectors and transmitters, and devices that operate, such as district bells, sound equipment, smoke suppression devices, and fire hydrants. (Setting data) is input for each fire alarm system. Since this interlocking data differs for each customer who installs a fire alarm system, it is also called customer data. Further, the control program for the monitoring process of the receiver may be changed for each fire alarm facility.

In recent years, a fire display device capable of displaying images is connected to a receiver, and event data relating to fire monitoring is transmitted from the receiver to the fire display device.
A system has been developed in which a display relating to fire monitoring is displayed on a fire display device by image display. Further, in such a system, there is a system that enables an operation on the receiver side using an operation unit (for example, a pointing device such as a mouse or a keyboard) provided in the fire display device.

[0005]

FIG. 9 shows a flow of operations for inputting and rewriting customer data and a control program in a conventional fire alarm system. Conventionally, in order to input or rewrite customer data and control programs, first, a sales office or customer clerk asks the user (customer) for the layout of the location of the fire alarm equipment, etc. The installation location of a fire hydrant or the like is confirmed (step A1). Next, customer data and a control program are created and input using a customer data creation tool (computer or the like) based on this information (step A2). Then, data is written to a ROM (Read Only Memory), which is a load medium that can be mounted on the receiver, using a rom writer or the like, data is written to a floppy disk (FD: a load medium), or the like, or via a communication cable. Create loadable communication data (step A3). On the other hand, the receiver and other devices of the fire alarm system are manufactured at a factory and then shipped to a sales office (Step A5), and then installed at a site used by a user (Step A6). The load medium created in step A3 is mounted on a receiver or the like at the site where the fire alarm system is installed (step A4). That is, a ROM in which customer data and control programs are written
Is set in the receiver, or data is input to the receiver via a storage medium such as a floppy disk or via a communication cable or the like to rewrite the data in the ROM. Rewriting of data in the ROM is performed, for example, by using an EPROM (Erasable and Programmable) such as a flash ROM.
ROM).

[0006] As described above, the setting data and control program written in the ROM as information unique to each fire alarm system, and information indicating what these setting data and control programs are (for example, Customer information such as customer name, property information indicating model number of installed fire alarm equipment, registration information such as fire department to which transmission signal is transmitted, system information indicating model number of internal control program, control Version information of programs and setting data, maintenance company information indicating maintenance companies and their contact information, etc.)
Is not directly related to anyone using the fire alarm system,
Further, the information is unnecessary information in normal times, but is important information for a person who installs or performs maintenance of the fire alarm system.

However, in the above-described conventional fire alarm system, the setting data, the control program, and the information indicating them cannot be easily confirmed. To check this information, for example, RO
Take out M and check it with a special reader,
There was no choice but to look at the labels and the like attached to storage devices such as M.

By the way, the receiver includes, for example, a display device such as a liquid crystal panel, a section display section for displaying an alarm area, and other processing during a sensor test or mask processing (processing for stopping the interlocking operation of some sensors). ) It has a plurality of output units such as indicator lights for displaying various states of the fire alarm system such as during. In addition, the receiver has a plurality of operation units such as a touch panel on a liquid crystal panel and a recovery switch. The fire display device connected to the receiver also has a display output unit and an operation unit. However, with the conventional fire alarm system,
The specifications of the output unit and operation unit of the receiver and fire display device are determined at the production stage, and even if you want to add or change the specifications of the output unit or operation unit after the system starts operating, this request can be met. Did not. In order to incorporate customer-specific specifications, there was no other way than to provide an output unit and an operation unit corresponding to these specifications from the stage of manufacturing the system.

Incidentally, in a fire alarm system equipped with an acoustic device, control is performed to notify a plurality of alarm states by, for example, timbres. That is, a plurality of alarm states are output by outputting different tone colors in a fire alarm, a failure alarm, and the like. Further, when a plurality of alarms are present at the same time, priority has been conventionally set for each alarm state, and priority output control for giving priority to notification of an alarm state with a high priority has been performed. For example, when a fire alarm and a failure alarm are present at the same time, the notification of a fire alarm with a higher priority is given priority. Such a fire alarm system has a function of stopping alarm notification by an acoustic device. For example, alarm notification is stopped by operating a sound stop switch. However, in the above-mentioned conventional fire alarm system, when the sound stop function is activated in a state where a plurality of alarm states are present, all alarm alarms are simultaneously stopped. In addition to the stop of the notification of the state, the notification of the low-priority alarm state is not performed. Therefore, there is a possibility that the low-priority alarm state may be overlooked without being recognized by the operator.

[0010] By the way, the conventional fire alarm system usually has a recovery operation unit (restoration switch) for restoring the state of the fire alarm system in the operation unit of the receiver or the operation unit of the fire display device. The recovery operation unit includes, for example, a fire alarm status, a fire alarm status, a detector alarm status held by a receiver, an alarm operation, a smoke prevention device and a fire hydrant interlocking status, and a sensor test status. It restores all the conditions that have occurred in the equipment. However, in the above-mentioned conventional recovery operation unit, the status that has occurred in the fire alarm system is recovered at once, so if multiple statuses have occurred, the status that has not yet been dealt with is also recovered. There was a problem that would. For example, if alarms in one district are determined to be false alarms after being alerted simultaneously in a plurality of different districts, operating the recovery operation unit in this state will restore the alarms in one district that were false alarms. Although good, there was a problem that the alarm status in the remaining districts was restored without any action being taken, and a time loss of, for example, 1 to 2 minutes would occur until the alarm was issued again.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and improves the operability of a fire alarm system. For example, the installer or maintainer of the fire alarm system can easily obtain necessary data, Enables processing operations according to needs,
It is an object of the present invention to provide a fire alarm system capable of performing an acoustic stop and a recovery operation that does not easily cause a warning state to be overlooked.

The input units i3 to i6 receive data of sensors such as a sensor and a gas detector, and respectively determine a fire, a gas leak, a pre-alarm whether the analog sensor has reached a preliminary alarm level, and a fire. Each determination during the signal accumulation operation is performed, and the determination result is output to the arithmetic unit C1. The input units i7 and i8 receive data of all types of devices connected to the receiver 1, and perform failure determination for all types of devices and DI determination (type determination) for all types of connected devices, respectively. And outputs the result of the determination to the arithmetic unit C1. The input unit i9 receives the data of the smoke elimination device and the hydrant, determines whether the smoke elimination device and the hydrant have been activated, and outputs the determination result to the calculation unit C1.

The operation section C1 operates the signals from the input sections i1 to i9 by an AND / OR / XOR circuit or the like and outputs the operation results to the output sections D1 to D6. The arithmetic unit C1 is configured using a programmable integrated circuit or using a relay circuit. Then, by changing the calculation content of the calculation unit C1, the user can define the processing operation of the receiver 1.

By the above-mentioned PLC, for example, the terminal (1)
By connecting the terminal and the terminal (15), it is defined that the interlock stop is executed when the custom switch 33a is turned on. By simultaneously connecting the terminals (1) and (12), it is defined that when the custom switch 33a is turned on, the interlocking stop is executed and the custom indicator 31b is turned on. Similarly, by connecting the terminal (9) and the terminal (10), it is defined that the custom indicator light 31a is turned on when the smoke prevention device or the fire hydrant is activated.

As described above, the user-defined sections (PLC, custom indicator lamps 31a to 31c, custom switch 33)
a, 33b), even if it is desired to add or change the specification of the processing operation of the receiver 1 after the system is operated,
Using the user-defined section, for example, new specifications can be added or changed while the fire alarm facility is installed. Further, by defining the custom indicator lamps 31a to 31c and the custom switches 33a and 33b, a variety of additions and changes in the specification of the processing operation of the receiver and the fire display device by the user is widened, and the user-defined section is easily and surely provided by the PLC. Can be defined. The user-defined unit does not have to include a user-definable display unit or operation unit. For example, the processing operation and the operation of the receiver 1 are performed on the condition of the state of the device connected to the receiver 1. The configuration that can be user-defined so that it can be performed is also included in the user-defined section.

Next, the sound stop switch 27 as sound output stopping means will be described. The receiver 1 is programmed to output a different alarm sound for each alarm state from a speaker inside the receiver when detecting various alarm states (specific situations). The program for the sound management processing includes a priority output function (priority output means) and an individual sound stop function (individual sound stop control means). The priority output function is a function of outputting a warning sound of a high-priority alarm state when a plurality of types of alarm states are detected in a conventional configuration. For example, priority is given to fire occurrence, gas leakage occurrence, pre-alarm occurrence, and failure occurrence in this order, and when these states overlap, the sound output corresponding to the higher priority state is given. Is performed.

The individual sound stop function is a characteristic configuration of the present invention. When the sound stop switch 27 is turned on, the sound output being output at that time is stopped and a plurality of alarm states are set. When the numbers overlap, the sound output corresponding to the alarm state with the next highest priority is performed. For example, if the fire sound stop switch 27 is turned on in a state where a fire occurrence and a failure occurrence are overlapped and a fire sound output is being performed, the fire sound output is stopped and a failure sound output is subsequently performed. Further, when the sound stop switch 27 is turned on, the failure sound output is also stopped, and all the warning sound outputs are stopped.

Next, the processing procedure of the sound management processing will be described in detail with reference to the flowcharts of FIGS. FIG. 5 is a flowchart illustrating a procedure of a sound management process performed by the control unit of the receiver. This sound management processing is started after the initialization processing has been completed after the power of the receiver 1 is turned on or after all of the receivers 1 have been restored by the restoration processing, and are executed in parallel with other control processing. Then, the sound control subroutine processing by the event occurrence (such as the occurrence of an alarm state) in step S1 and the step S2
The sound stop operation subroutine process related to the sound stop switch 27 is repeatedly executed at high speed.

FIG. 6 is a flowchart showing the processing procedure of the subroutine "Sound control by event occurrence" performed in step S1 of FIG. In the sound control subroutine processing by the event occurrence, steps S3, S8,
At S12 and S18, the occurrence of each of a fire alarm, a gas leak alarm, a pre-alarm, and a failure alarm is determined. If an alarm condition occurs, steps S4, S11, S17,
In S23, a fire sound, a gas sound, a pre-alarm sound, and a failure sound corresponding to the alarm state are sounded. However, during that time, steps S10, S15, S2
In step 1, it is determined whether or not a high-priority alarm is sounded at the present time. If the alarm is sounded, no new sound is generated. If a high-priority alarm condition occurs, the subroutine process is terminated without determining that a low-priority alarm condition has occurred.

Steps S5, S9, S16, S2
In step 2, it is determined whether or not each of the alarm states that have occurred has been cancelled. If the alarm states have been canceled, the sound is stopped in step S24. However, during that time, steps S6, S13,
In S19, it is determined whether there is an alarm state having a lower priority than the released alarm state. If there is such an alarm state, in steps S7, S14, and S20, an alarm state having a higher priority is set. A sound is sounded, and this subroutine processing ends. In other words, a priority output function of outputting a high-priority alarm sound is realized by the sound control subroutine processing by the event occurrence.

FIG. 7 is a flowchart showing the procedure of a subroutine of the sound stop operation process performed in step S2 of FIG. When the sound stop operation process is started, first, in step S30, the sound stop switch 2
It is determined whether or not 7 has been turned on. If there is an operation, the process proceeds to the sound stop process from step S31, and if there is no operation, this subroutine process is terminated as it is. The sound stop processing from step S31 includes steps S31 and S3.
In steps S5, S39, and S43, the sounding sound is determined. If there is no sounding, the subroutine processing is terminated. If there is any sounding, steps S32, S36, and S40 are performed. , S44,
The sound is stopped.

Further, after the sounding is stopped, it is determined in steps S33, S37 and S41 whether or not there is an alarm state having a lower priority than the alarming state of the stopped sounding. The subroutine is terminated. If there is any, in steps S34, S38, and S42, a sound is sounded in the alarm state with the next highest priority, and the subroutine processing is terminated. That is, the above step S
The processes of 33, S34, S37, S38, S41, and S42 realize an individual sound stop control function of outputting a warning sound when a low-priority warning state occurs after the sound stop.

Next, the recovery switch 28 functioning as individual recovery means will be described. In the fire alarm system of this embodiment, a signal from a detector (fire detector or gas detector) or a transmitter is monitored by the receiver 1, and a signal indicating an abnormality such as a fire alarm is transmitted from the detector or the transmitter. When output, when the signal of gas leak detection is output from the gas detector, when the output value of the analog sensor reaches the preliminary alarm level,
Alternatively, when a failure such as a short circuit or a disconnection occurs in the sensor, the trunk line, and the sensor line and the failure is detected by the receiver 1, the receiver 1 executes a processing operation corresponding to the abnormality.
These functions constitute alarm processing means and are conventionally known.

For example, if a fire signal is output, a fire signal accumulation operation is performed for a certain period of time as a fire signal detection process, and after the indicator lamp 21a is turned on, it is determined that a fire has occurred and the division display unit 23 and the sensor are detected. The display output of the number display unit 24, the sound of the fire sound from the receiver 1, the lighting of the fire representative light 21, the alarm output from the area bell and the sound device installed in each area, and the discharge prevention corresponding to the issued sensor. Processing operations such as operation of smoke equipment and fire hydrants are performed. The fire signal detection processing and the accumulation operation are also one of the processing operations of the receiver 1.
When a failure is detected, processing operations such as lighting of the failure representative light 29 and lighting of the indicator lights 29b to 29e corresponding to the detected failure are executed.

In the fire alarm system of this embodiment, the menu and operation buttons displayed on the liquid crystal display device 8 are operated by using the cursor keys 9 and the numeric keys 10 as operation units, for example, to detect the fire. A device test and a mask process for stopping the interlocking operation of some sensors can be executed. These functions constitute operation processing means and are conventionally known.

The restoration switch 28 is a switch for restoring the processing operation executed by the receiver 1 upon detection of the above-described abnormality and the processing operation executed by operating the operation unit. The recovery process by turning on the recovery switch 28 is as follows.
It is a feature of the present invention, and when there are a plurality of processing operations to be executed or waiting to be executed in the receiver 1, it is programmed to restore only one processing operation without recovering all the operations collectively. I have. Specifically, only the processing operation in which a predetermined display is performed is restored. The predetermined display can be changed for each processing operation. However, it is preferable that the predetermined display be a display that can be reliably recognized as being executed by looking at the display operation panel 2 of the receiver 1.

That is, if the processing operation is executed based on the detection of a fire report, the processing operation related to the fire report displayed on the section display unit 23 is restored, and the process related to the fire report not displayed due to overflow is performed. Operation is not restored.
The sensor test processing is restored if the indicator lamps 21b and 21c are on during execution.

The receiver 1 is not limited to the configuration in which only the individual recovery processing is provided. For example, two recovery switches are prepared so that both the individual recovery processing and the conventional collective recovery processing can be executed. Alternatively, the function of the recovery switch 28 may be switched between the function of the individual recovery processing and the function of the conventional batch recovery processing by an internal setting. Moreover, you may classify according to the length of operation time.

The procedure of the individual recovery process will be described below with reference to a flowchart. FIG. 8 shows FIG.
It is a flowchart which shows the processing procedure of the individual recovery process performed by the control part of the receiver of FIG. This individual recovery process
This is a process started by turning on the recovery switch 28. When this process is started, first, in step S50, the on-operation of the recovery switch 28 is confirmed. If the operation is confirmed, the process proceeds to step S51. If the operation is not confirmed, the individual recovery process ends. Step S51
In step S52, it is determined whether or not there is a preset display among the processing operations that are being executed or waiting to be executed. If there is, the process proceeds to step S52. If not, the individual recovery process is terminated. . Here, the display that is set in advance can be changed for each processing operation, but a display that can be reliably recognized as being viewed by the display operation panel 2 of the receiver 1. It is preferred that

In step S52, a recovery process is performed for the processing operation determined to be displayed in step S51, and the flow advances to step S53. In step S53,
In step S52, the display relating to the restored processing operation is erased, and processing for updating to the display of the other processing operation is performed, and the individual restoration processing ends.

Conventionally, when a plurality of alarm states are generated in an overlapping manner, or when there are a plurality of processing operations in an execution state or an execution waiting state, the sound stop or the recovery processing stops the sounding of all alarm states, Although the processing operations of the above-mentioned steps have been collectively restored, according to the individual sound stop processing and the individual restoration processing described above, the operator has
Only sound sounds and processing operations that can be recognized by the sound output and display of the are released, and other unrecognizable sound sounds and processing operations are continuously executed, so even if there are multiple alarm states, do not overlook the alarm state , And can perform sound stop and recovery processing.

The present invention is not limited to the fire alarm system of this embodiment. For example, in this embodiment, the display output of the unique information, the user definition unit, the individual restoration means, the individual sound stop control Although the means are provided in the receiver 1 respectively, they may be provided in a fire display device connected to the receiver 1. In addition, the detailed structure and method, such as the display contents and format of the specific information, the display unit and the operation unit as the user-defined unit, the processing procedure of the individual restoration processing and the individual sound stop processing, and the like, are the gist of the invention Can be appropriately changed without departing from the range.
