Description

The present invention relates to fire alarm equipment that monitors fires by connecting multiple types of terminals, such as fire detectors and smoke prevention equipment, each having a unique address set on a signal line drawn out from a receiver.

Conventionally, fire alarm equipment known as type R connects a terminal such as a fire detector with a transmission function with a unique address to the signal line drawn out from the receiver, and when a fire is detected, , based on a fire interrupt from a fire detector, the receiver issues a search command to identify the address of the fire detector that triggered the alarm, collects fire data such as smoke concentration and temperature, and searches the fire data for the specified fire. If the threshold is exceeded, it is determined that there is a fire, the fire representative light is turned on, and a main audible alarm is output.Furthermore, a fire outbreak message, fire location, fire occurrence time, and receiver device are displayed on the display installed in the receiver. A fire alarm screen with operational guidance etc. is displayed. Such a receiver can display the operating status of each terminal device.

FIG. 11 shows a terminal information display screen displayed on the display of a receiver during conventional construction work in which terminal states of different types are displayed on one screen. As shown in FIG. 11, the terminal information display screen 200 includes a designated operation section 202 in which operation buttons for fire alarm, smoke prevention, interlocking, failure terminal, gas, monitoring, P input, interlocking destination, etc. are arranged. For example, if all the operation buttons except the linked destination are operated by clicking on the screen as indicated by black circles, the terminal status display section 204 will display the terminal status display section 204 based on the terminal information stored and managed by the receiver. The status of terminals connected to the signal line from is displayed in order of address.

Here, the maximum address that can be set for the signal line from the receiver is, for example, 255 addresses, and there are restrictions on the number of addresses that can be displayed on the terminal status display section 204. Therefore, by scrolling the screen, you can select the required address. You can display and check the terminal status.

Japanese Patent Application Publication No. 2007-265353 Japanese Patent Application Publication No. 2007-219870 JP2002-222471A Japanese Patent Application Publication No. 11-024876

However, when checking the terminal status of such a receiver, by specifying multiple types by operating the designation operation section 202 shown in FIG. If you want to narrow down the terminal status displayed on the screen to a specific type and view the terminal status, it is necessary to display the terminal status on the screen by specifying the type to narrow down again, and it is necessary to specify the terminal status from among the many types of terminals. There is a problem in that it takes time and effort to narrow down the terminal status to the terminal types and display it on the screen.

In addition, in an interlock test in which smoke prevention equipment is controlled in conjunction with receiving a fire alarm signal from a fire detector, the terminal status of the fire detector that is the interlock source is displayed on the screen according to the type specified, and then the screen is displayed. It is necessary to specify the terminal status of the specific fire detector that has been detected, specify the type of the interlocking destination, and switch the display to the display screen of the interlocking destination terminal status. Since the previous terminal status is displayed on a separate screen, there is a problem in that it takes time and effort to confirm the interlocking relationship and confirm the terminal status by interlocking control. Similarly, it takes time and effort to understand the status of the interlocking target terminal when a fire occurs and to check the history of changes in the status of the interlocking target terminal after the fire occurs.

As shown in FIG. 2, the terminal information 52 is divided by system, address, type, line, and floor, and display messages with arbitrary numbers include, for example, "Theatre 1F East" and "Theatre 1F East-1." The district name is stored, followed by the operating status of the terminal, such as ``Fire'' if a fire is detected by an analog smoke detector, or ``Confirmation'' based on closed detection if a fire door is controlled in conjunction. Then, interlock destination information such as addresses "002", "003", and "004" is stored as interlock destination terminal information.

Note that addresses whose fields after the type are blank in the terminal information 52 are unused addresses. In addition, the terminal information 52 stored in the main CPU 26 is used to display fire area display and interlock information during operation when the fire alarm system construction work is completed and the receiver 10 is switched to fire monitoring mode and the fire monitoring control unit 46 is functioning. It is used as is as terminal information for control.

(Receiver fire monitoring control)
The fire monitoring control during operation when the construction work of the fire alarm equipment is completed and the receiver 10 is switched to the fire monitoring mode is as follows.

Taking the sub CPU 30-1 of the sub CPU board 28-1 as an example, the sub CPU 30-1 instructs the transmission section 32-1 to transmit and receive signals with the analog fire detector 14 according to a predetermined communication protocol. fire monitoring and control.

The downstream signal from the transmission section 32-1 to the analog fire detector 14 is transmitted in voltage mode. This voltage mode signal is transmitted as a voltage pulse that changes the line voltage of signal line 12-1 between, for example, 18 volts and 30 volts.

On the other hand, the upstream signal from the analog fire detector 14 to the transmission section 32-1 is transmitted in current mode. In this current mode, a signal current is passed through the signal line 12-1 at the timing of bit 1 of the transmission data, and an upstream signal is transmitted to the receiver 10 as a so-called current pulse train.

During normal monitoring, the fire monitoring control by the sub CPU 30-1 instructs the transmitter 32-1 to transmit a broadcast batch AD conversion signal including a batch AD conversion command at regular intervals. The analog fire detector 14 that receives this batch AD-converted signal detects and holds the smoke concentration or temperature as sensor data. Subsequently, the sub CPU 30-1 transmits a calling signal including a polling command that sequentially specifies terminal addresses.

When the analog fire detector 14 receives a call signal having an address that matches its own address, it transmits a response signal containing the analog data of the sensor held at that time to the transmission section 32-1. Furthermore, when the analog fire sensor 14 detects that the analog data of the sensor has reached a predetermined fire pre-level lower than the predetermined fire determination level, it transmits a fire interrupt signal to the transmission section 32-1.

When the sub CPU 30-1 receives the fire interrupt signal via the transmission unit 32-1, the sub CPU 30-1 transmits a group search command signal to identify the group including the analog fire detector 14 that is detecting a fire, and then An internal search command signal is sent to specify the address of the analog fire detector 14 that is detecting a fire, and analog data of the sensor is intensively collected and transmitted to the main CPU 26 via the serial transfer bus 34.

The main CPU 26 compares the analog data received from the sub CPU 30-1 with a predetermined fire judgment level (fire threshold), and when the analog data reaches the fire judgment level, it judges that there is a fire, and displays the fire representative on the display section 38. lights up, causes the speaker of the acoustic alarm unit 42 to output a predetermined main acoustic alarm indicating the occurrence of a fire, causes the display 36 to display fire alarm information including the location of the fire based on the address of the sensor where the fire was detected, Further, the alarm shifting section 44 outputs a fire alarm signal to the outside to perform predetermined alarm shifting control and the like.

The fire monitoring control by the sub CPU 30-2 and the transmission unit 32-2 provided on the sub CPU board 28-2 is also the same as in the case of the sub CPU board 28-1 described above. In addition, regarding the sub CPU 30-3 and the transmission section 32-3 provided on the sub CPU board 28-3, when a fire is detected in the main CPU 26, the sub CPU 30-3 and the transmission section 32-3 Interlocking control of the smoke equipment 24 is performed.
