Description

  The present invention relates to a fire alarm system that notifies when a fire has occurred in a building, and more particularly to a fire alarm system that can promptly notify a fire.

  Automatic fire alarm equipment is often used as equipment for detecting and notifying a fire in a building. As is well known, the automatic fire alarm system sends a signal to the receiver when the detector installed in the building detects heat, smoke or flame generated by the fire, and the receiver displays the location of the fire. At the same time, the people in the building will be informed that a fire has occurred through the emergency warning system. A person who discovers a fire presses the button on the transmitter, and a signal is sent to the receiver to notify the occurrence of the fire.

  In the power plant, an automatic fire alarm system is used to notify the fire in the building. In addition, when an operator or a worker detects a fire in a power plant, this is communicated to the operator of the central control room using a fixed paging device or a portable extension telephone, and the central control room that is informed is informed. Operators start the emergency alarm equipment activation device provided in the automatic fire alarm system, broadcast the occurrence of fire and its location via the emergency alarm system, and notify the person in the power plant of the fire occurrence Many methods are also adopted.

Regarding fires in buildings, when the automatic fire alarm system detects a fire and notifies the fire via a district bell or sound device, it is performed regardless of the location of the fire and the location of the person in the building. It has been pointed out that the residents do not know where the fire broke out and how to evacuate. In order to solve this problem, the area information reported by the sensor is acquired from the receiver, and the location information of the mobile phone slaves owned by each individual is acquired and used for evacuation to the mobile phone slaves in the alert area. Has been proposed (see, for example, Patent Document 1). Similarly, an evacuation guidance method in the event of a disaster in a power plant / factory has been proposed (see, for example, Patent Document 2).

  With regard to fires in buildings, power plants, and factories, evacuation guidance in the event of a fire is also an important matter, but it goes without saying that it is important to detect or detect a fire earlier and to report it. In order to output a signal by detecting that the ambient temperature has exceeded a predetermined rate of increase or has reached a predetermined temperature, the heat detector of an automatic fire alarm facility that has been generally used in the past. There is a certain time difference from when the fire occurs until the sensor outputs a fire detection signal. The same applies to smoke detectors and flame detectors. It is necessary to detect a slight temperature change and output a fire detection signal in order to be triggered at the same time as a fire occurs. It is inevitable that a certain time difference occurs.

  Also, if a person who finds a fire operates the button on the transmitter, a signal is sent to the receiver to notify the occurrence of the fire. Since it is necessary to move and operate the transmitter, a certain amount of time is naturally required. In addition, in power plants, the occurrence of a fire can be notified by contacting the operator of the central control room using a fixed paging device or a portable extension telephone. It takes a certain amount of time to pick up the handset, listen to the location of the fire, and broadcast the fire. Thus, the current fire detection and notification method requires a certain period of time from the occurrence of a fire to the notification, and a more rapid development of a fire notification system is desired.

  An object of the present invention is to provide a fire notification system capable of performing fire notification more quickly.

  A fire alarm system according to the present invention includes a portable terminal, a plurality of base stations installed in a building, a private telephone equipment having a private branch exchange function and a telephone server capable of outputting the location information of the base station, Receives fire occurrence signals including multiple detectors and transmitters installed in the building, and the detectors and / or transmitters, and notifies the occurrence and location of fires via display devices and emergency alarm equipment. An automatic fire alarm facility comprising a receiver that performs a predetermined dial number only when the telephone server is connected to the receiver and receives a predetermined dial number indicating the occurrence of a fire from the portable terminal. The position information of the base station close to the mobile terminal that transmitted the message is output to the receiver, and the receiver receives the position information of the base station from the telephone server. Through the device and emergency warning equipment, wherein the notifying the occurrence and fire place fire.

  According to the fire alarm system of the present invention, the telephone server of the local telephone equipment and the receiver of the automatic fire alarm equipment are connected, so that a person carrying a mobile terminal finds a fire and dials it through the mobile terminal. When the number is contacted, the telephone server can send this information to the automatic fire alarm facility. Since the fire information sent by the person who discovers the fire is sent to the telephone server through the base station close to the fire site, the telephone server will send the most information to the mobile terminal that was sent when the specified dial number indicating the occurrence of the fire was received. The location of the nearest base station is designated as the location of the fire and is sent to the automatic fire alarm system. The telephone server outputs the base station position information to the receiver only when a predetermined dial number is received. Therefore, when the receiver receives the base station position information from the telephone server, the fact that a fire has occurred and the base station The location of the fire is known from the location information. Furthermore, even if the receiver is a storage type receiver, the receiver immediately notifies the occurrence of the fire and the location of the fire through the display device and the emergency alarm facility based on the information from the telephone server. Can be done more quickly. In addition, since the fire alarm system of the present invention is basically composed of a local telephone facility and an automatic fire alarm facility, the present invention can be easily applied to a building having these facilities.

  Moreover, the fire alarm system of the present invention, in addition to the above configuration, the building has a plurality of areas partitioned by a plurality of rooms and / or partition members inside, and the base station and the detector are: At least one or more is attached to each room and / or each area.

  According to the fire alarm system of the present invention, the building has a plurality of areas divided by a plurality of rooms and / or partition members inside, and the base station and the detector are provided in each room and / or each area. Since at least one or more are attached to, it is easy to identify the location of the fire. In addition, when there are multiple areas partitioned by multiple rooms and / or partition members inside the building, visual fire detection cannot be done without going to or near the location where the fire occurred. The location where the occurrence of the information is transmitted is close to the location where the fire occurred, and the location where the fire occurred can be accurately identified.

  In addition to the above configuration, the fire alarm system of the present invention is characterized in that the building is a building in which the inside of the building cannot be seen or is difficult to see from the outside of the building.

  According to the fire alarm system of the present invention, the inside of the building is not visible or difficult to see from the outside of the building, so that a fire inside the building cannot be found from the outside of the building. Therefore, the fire information generated inside the building is not transmitted from the outside of the building, and the location of the fire is not mistaken.

  In addition to the above-described configuration, the fire alarm system of the present invention is characterized in that the mobile terminal is a PHS.

  According to the fire alarm system of the present invention, since the portable terminal is a PHS, the area that can be covered by one base station is narrow. As a result, the location of the fire can be accurately identified. Furthermore, the equipment cost is low and the equipment can be easily introduced.

  The fire can be notified before the sensor detects the fire by the fire notification system of the present invention. In addition, when a fire is to be notified via a transmitter, it is necessary to move to the place where the transmitter is located and activate it, but when a mobile device detects a fire, it should immediately notify that a fire has occurred. Can do. Further, since the automatic fire alarm equipment is automatically connected by dialing a predetermined dial number, the time for contacting other persons as in the prior art is shortened. Thus, the fire notification system of the present invention can perform fire notification more quickly than the conventional fire notification system.

FIG. 1 is a diagram showing a schematic configuration of a fire alarm system 1 as an embodiment of the present invention. Here, a fire alarm system applied to the building 20 in the power plant premises will be described as an example. The fire alarm system 1 is roughly divided into a local telephone facility 10 using a plurality of mobile terminals and an automatic fire alarm facility 30 that senses and notifies the occurrence of a fire. The local telephone equipment 10 includes a plurality of mobile terminals, specifically, a PHS (Personal Handy-phone System) 11 and a plurality of base stations 12 (12 ₁ , 12 ₁ , 12) that receive radio waves transmitted from the PHS 11 or transmit radio waves to the PHS. 12 ₂ ,..., 12 _n ), and a telephone server 13 having a function of a telephone exchange that is connected to the base station 12 and controls communication of the PHS 11.

The PHS 11 (11 ₁ , 11 ₂ ,..., 11 _n ) is a portable terminal that has been generally used in the past, and is owned by a power station operator or worker one by one. Or carry it whenever you work in the building. A plurality of base stations 12 are installed in the power plant premises including the target building. FIG. 2 is a plan view showing a part of the building 20 in the power plant premises, and is a view showing the location of the installed base station 12 and the detector 31 of the automatic fire alarm facility 30. In the building 20, a plurality of areas are provided by partition members such as a plurality of rooms and walls so as not to be affected by disasters and the like, and devices and the like are installed in each room or area. As shown in FIG. 2, at least one base station 12 is installed in each room and each area. This is because the base station 12 of the PHS 11 has a narrow area that can be covered by one base station 12 and has many walls to ensure good communication. In addition, although illustration is abbreviate | omitted, several fixed paging apparatuses are also installed in the building 20. FIG. This number is overwhelmingly smaller than the number of base stations 12. Each base station 12 is connected to the telephone server 13 by an optical cable 14.

  The telephone server 13 has a function of a telephone exchange that controls communication of the PHS 11 and a function of outputting fire information to the automatic fire alarm facility 30. The telephone server 13 includes an input / output unit 15, a processing unit 16, and a storage unit 17. The input / output unit 15 is connected to the base station 12 and the public telephone line through an external interface and is also connected to a receiver 33 of the automatic fire alarm facility 30. Connect with. Further, an input device such as a keyboard (not shown) and a display device such as a CRT are connected to input data or display data. The processing unit 16 uses the data input via the input unit 15 and the data described in the storage unit 17 to perform processing necessary for controlling communication of the PHS 11 and processing for connecting to a public telephone line. . Further, when data indicating that the predetermined dial number is transmitted from the PHS 11 is input, the radio wave of the PHS 11 from which the predetermined dial number is transmitted is received most strongly among the location information of the base station 12 stored in the storage unit 17. The location information of the base station 12 that has been transmitted, that is, the base station 12 closest to the PHS 11 from which the predetermined dial number is transmitted, is retrieved and output to the automatic fire alarm facility 30 via the input / output unit 15.

  The storage unit 17 stores a program necessary for the processing unit 16 to process data, data input via the input / output unit 15, and the like, and includes a position registration database, and includes a unique number of the PHS 11 and its current position, And the positional information which matched the specific number and address of the base station 12 is memorize | stored. The private telephone equipment 10 having the above configuration receives a predetermined dial number from the PHS 11 and automatically receives the location information of the base station 12 at the location closest to the PHS 11 from which the predetermined dial number is transmitted. Except for the function of outputting to the fire alarm facility 30, the basic functions are the same as those of the private telephone facility 10 that has been generally used. As will be understood, when a predetermined dial number is transmitted from the PHS 11, this is received, and the position information of the base station 12 closest to the PHS 11 from which the predetermined dial number is transmitted is output to the automatic fire alarm system 30. If it is a local telephone equipment provided with the function to perform and a local telephone exchange function, it can be used without being limited to the local telephone equipment 10 shown in this embodiment.

The automatic fire alarm system 30 which is one of the general disaster prevention facilities of the power plant includes a plurality of sensors 31 (31 ₁ , 31 ₂ ,..., 31 _n ) that are installed in the building and sense the fire and the operation of the power plant. Transmitters 32 (32 ₁ , 32 ₂ ,..., 32 _n ) that report when a worker or a worker finds a fire are provided. The sensor 31 and the transmitter 32 are connected to the receiver 33 via the transmission line 34, and a signal that detects a fire or a signal that reports a fire is sent to the receiver 33. When the receiver 33 receives the fire occurrence signal, the receiver 33 displays the location of the fire on the indicator lamp 35 and the CRT 36 installed in the general disaster prevention panel 40, and also rings the bell 38 installed in the building 20, and further emergency broadcast. The facility 37 is used to broadcast the location of the fire, etc., and notify the occurrence of the fire and the location of the fire.

  The sensor 31 includes a heat sensor that detects heat and senses the occurrence of a fire, and a smoke sensor that senses smoke and senses the occurrence of a fire, and these sensors are sensors having a transmission function. Each sensor 31 has a unique number and an address. The heat sensor that can be used here is a differential heat sensor that senses that the rate of temperature increase has exceeded a predetermined value, and a constant temperature heat sensor that senses that the temperature has exceeded a predetermined value. It is possible to use a conventional heat sensor such as a thermostat. Similarly, as the smoke detector, an optical smoke detector and an ionization smoke detector which are generally used in the past can be used. Furthermore, a flame detector that senses flame can also be used. As shown in FIG. 2, one or more detectors 31 are installed in each room and each area of the building 20, and can quickly detect a fire that has occurred in each room and each area. Further, the number of detectors 31 installed is larger than the number of base stations 12 installed. The transmitter 32 is a push button type transmitter, and is a transmitter generally used conventionally. These are connected to the receiver 33 through the transmission line 34.

  The receiver 33 designates an address via the transmission line 34 and sequentially sends a signal to each sensor 31, and detects a fire by a signal returned from each sensor 31. When the fire signal is received, the sound equipment (not shown) is sounded, and the location of the fire is displayed on the display device 35 and the CRT 36. When a fire signal is received, the signal is transmitted to the emergency broadcast facility 37 and the bell 38. The emergency broadcasting equipment 37 includes speakers 39 at various locations in the building, and when a fire occurrence signal is received, broadcasts the location of the fire and the like, and notifies the person in the power plant premises of the occurrence of the fire and its location. The same applies when the transmitter 32 is pressed. The bell 38 rings when a signal is received from the receiver 33.

  The automatic fire alarm facility 30 having the above-described configuration is the same as the function of an automatic fire alarm facility that has been generally used. However, the automatic fire alarm facility 30 has a local telephone facility 10 as described below. , Receiving fire occurrence information via the local telephone equipment 10, and automatically informing the occurrence of fire based on this information. Therefore, similarly to the sensor 31, the receiver 33 includes a database in which the unique number and address of each base station 12 are associated. The automatic fire alarm system that can be used in the fire alarm system of the present invention is not limited to the automatic fire alarm system 30 shown in the present embodiment as long as it is an automatic fire alarm system having the above-described functions. May be provided.

  When an operator patroling the building 20 or an operator working in the building 20 finds a fire, the operator or the worker reports the occurrence of the fire with the PHS 11 carried by the operator. At this time, instead of dialing the extension number of the central control room and notifying the operator of the central control room of the fire, a predetermined dial number for notifying the occurrence of a fire when a fire is detected, for example, 99 is dialed. The signal from the PHS 11 is sent to the telephone server 13 via the base station 12 as in the case of a normal private telephone number. The telephone server 13 identifies the base station 12 that is closest to the PHS 11 that has transmitted the radio wave, as in the case of normal private telephone communication. At this time, when the telephone server 13 determines that the received signal is the specific number 99 for notifying the fire, the telephone server 13 transmits the address of the specified base station 12 to the receiver 33 of the automatic fire alarm facility 30. When the receiver 33 receives the address of the base station 12 from the telephone server 13, the receiver 33 refers to a database that associates the address and location of each base station 12 in the same manner as when the fire signal from the sensor 31 is received. The location of the base station 12 is specified as the location where the fire occurred. Thereafter, the same operation as when the detector 31 detects a fire is performed to notify the fire. Note that the base station position information transmitted from the telephone server 13 to the receiver 33 may be the base station unique number instead of the base station address. Since the receiver 33 includes a database in which the unique number and address of each base station 12 are associated, the address can be obtained from the unique number of the base station.

  When the receiver 33 receives the address of the base station 12 from the telephone server 13, the receiver 33 immediately identifies the location of the fire and notifies the fire. Among receivers that receive a signal from the sensor 31 and notify a fire, there is a receiver having a storage function that notifies a fire after the signal from the sensor 31 continues for a certain period of time for the purpose of preventing false alarms. . Even in such a storage-type receiver, the signal from the telephone server 13 is a signal that the operator or worker visually confirms and fires, so there is no need to worry about false alarms. For this reason, when the receiver 33 receives the address of the base station 12 from the telephone server 13, it immediately identifies the location of the fire and notifies the fire. Thereby, a fire can be alert | reported rapidly.

  In a case where two or more base stations 12 are installed in the area where the building 20 is partitioned, or the room is wide and two or more base stations 12 are installed in one room. In such cases, there is a concern that the location of the fire and the location where the fire was reported are different. For example, if base stations 12 are installed near the entrance and exit of the room, and an operator who enters the room from the entrance finds a fire that is occurring near the exit of the room, the base station 12 is located near the exit where the fire is occurring. It seems that it is common to report a fire from the PHS 11 near the entrance instead of moving and reporting the fire. In such a case, since the telephone server 13 transmits the address of the base station 12 installed near the entrance of the room to the receiver 33, it is different from the vicinity of the room exit where the fire actually occurs. Even if there is, it can be notified that a fire has occurred in the same room.

  If you find a fire in a very far away place and report it from a far away place, the location of the fire will be greatly different and inconvenience will occur, but in the case of an area partitioned by a room or partition member as shown in this embodiment It is not possible to find a fire that is happening in a very far away room, and the present invention can be used effectively. Even if there are no rooms or areas partitioned by partition members, the entire floor can not be overlooked in factories where machines are installed in various places or department stores where many product shelves are installed. In that case, the fire alarm system functions effectively. In addition, when a fire inside a building is discovered from outside the building, it is assumed that the location where the fire occurred and the place where the fire was reported are greatly different, but from outside the building such as buildings, factories, department stores, etc. The present invention can be used more suitably in a building where the inside of the building cannot be seen or is difficult to see.

  When an operator or a worker discovers a fire as described above, the fire can be notified quickly by notifying this immediately via the PHS 11. A fire may occur in a place where there is no operator or worker, or the operator or worker may not be aware of the fire. In such a case, the sensor 31 can be used as in the conventional building fire alarm system. A fire can be notified. As described above, the fire notification system 1 of the present invention can notify the fire more promptly by the cooperation of the fire information by the PHS 11 and the fire detection by the sensor 31. In addition, as shown in the above embodiment, the fire alarm system 1 of the present invention has a basic equipment configuration of a fire alarm system that is a local telephone equipment and an automatic fire alarm equipment that are generally used conventionally. In existing power plants, factories, and buildings having these facilities, the present invention can be easily introduced.

  In the above-described embodiment, an example in which PHS is used for a mobile terminal is shown. However, the mobile terminal is not limited to PHS, and a mobile phone, a PDA (Personal Digital Assistant) having a communication function, or the like is used. Can do. Although it is possible to use a dedicated mobile terminal to notify the occurrence of a fire, if a mobile terminal is different from the telephone that is the means of communication for operators, workers, and store staff at power plants, factories, department stores, etc. It is necessary to always carry a portable terminal for use and a portable terminal for reporting the occurrence of a fire, which is not convenient. Therefore, the mobile terminal is preferably a telephone, a mobile phone having a call function, or PHS, and more preferably PHS in terms of the number of base stations to be installed.

It is a figure showing the schematic structure of fire alarm system 1 as one embodiment of the present invention. It is a top view which shows a part of building 20 of FIG. 1, Comprising: It is a figure which shows the location of the detector 31 of the installed base station 12 and the automatic fire alarm equipment 30.
