Description

[Technical Field]

[0001] The present invention relates to a fire-related information display device such as a fire receiver that detects the occurrence of a fire based on information from a plurality of terminal devices. [Background technology]

[0002] Conventionally, fire receivers used in fire alarm systems that monitor factors that can cause fires, such as smoke generation, temperature rise, and gas leaks, have been installed in disaster prevention centers, control rooms, etc. Fire receivers determine whether a fire has occurred by receiving signals from one or more terminal devices installed in each fire monitoring area.

[0003] In addition, fire extinguishing system control panels that monitor fire extinguishing equipment such as sprinkler systems are also installed in disaster prevention centers, management rooms, etc., and determine whether or not a fire has occurred by receiving fluctuations in the pressure inside the pipes from terminal devices.

[0004] For such fire alarm systems and fire extinguishing systems, there is conventional technology that prevents fire monitoring from being affected when providing guidance on operation methods or performing simulations, and makes it easy to learn how to actually operate them and how to respond in the event of a fire (see, for example, Patent Document 1).

[0005] More specifically, the disaster prevention receiver according to Patent Document 1 has a display unit that can guide users on how to operate the operation unit, and has a function of displaying the operation method and the status in text. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-208673 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the conventional techniques have the following problems. The prior art disclosed in Patent Document 1 aims to improve operability by displaying operation methods and the like in text. For an operator who has a good understanding of how and where to operate the receiver, text instructions are sufficient. However, for an operator who does not fully understand how to operate the receiver, text instructions alone may be difficult to understand, and a function that enables such operators to operate quickly is desired.

[0008] Similarly, there is a demand for a function that allows the operator to see at a glance what an alarm or the like is based on.

[0009] The present invention has been made to solve the above-mentioned problems, and has as its object to provide a fire-related information display device that can improve the operability for the operator. [Means for solving the problem]

[0010] The fire-related information display device of the present invention is a fire-related information display device that includes a receiving unit that receives fire-related information from each of a plurality of terminal devices, a display unit that displays fire judgment information necessary for an operator to judge whether a fire has occurred, and a control unit that generates fire judgment information based on the fire-related information received by the receiving unit and displays the generated fire judgment information on the display unit.The control unit has an illustration display function that, when displaying the fire judgment information as text, displays on the display unit an illustration of the operations that the operator should next perform in accordance with the fire occurrence situation, and when displaying the fire judgment information as text, displays on the display unit an illustration of the operations related to switch operations or reset operations on the fire-related information display device as the operations that the operator should next perform in accordance with the fire judgment information, thereby realizing an operability improvement function. [Effects of the Invention]

[0011] According to the present invention, when displaying fire-related information necessary for an operator to determine whether or not a fire has occurred based on the fire-related information received from each of a plurality of terminal devices, an illustration can be displayed. As a result, a fire-related information display device that can improve the operability of the operator can be obtained. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a fire receiver, which is one of the fire-related information display devices of the present invention, will be described below with reference to the drawings.

[0014] Embodiment 1 Fig. 1 is an overall configuration diagram of a fire alarm system according to a first embodiment of the present invention. The fire alarm system shown in Fig. 1 is configured to include a fire receiver 10, four terminal devices 20(1) to 20(4), and a repeater 30. Here, two terminal devices 20(1) and 20(2) and the repeater 30 are directly connected to the fire receiver 10. Furthermore, two terminal devices 20(3) and 20(4) are directly connected to the repeater 30, and are connected to the fire receiver 10 via this repeater 30. Note that the numbers of terminal devices 20 and repeaters 30 are not limited to those shown in the example of Fig. 1.

[0015] The fire alarm system shown in Fig. 1 is a so-called R-type fire alarm system. Therefore, the four terminal devices 20(1) to 20(4) output measurement results, detection results, etc. as analog signals, and the fire control panel 10 determines whether or not a fire has occurred based on the reception of these analog signals.

[0016] Representative examples of the terminal device 20 include the following photoelectric analog sensors and thermal analog sensors. Photoelectric analog detector In a fire monitoring area, the light emitted from the light-emitting unit is dimmed by the influence of smoke and received by the light-receiving unit, thereby enabling the detection of the occurrence of smoke as an analog value. Alternatively, the light emitted from the light-emitting unit is scattered by smoke particles and the scattered light is received by the light-receiving unit, enabling the detection of the occurrence of smoke as an analog value. Thermal analog detector In a fire monitoring area, it corresponds to a heat detector that can detect heat as an analog value.

[0017] In addition, measuring instruments for measuring temperature, air pressure, humidity, CO gas, etc. can also be used as terminal devices that can measure the surrounding conditions in the fire monitoring area.

[0018] Furthermore, various sensors such as those listed below can also be used as terminal devices. Pressure sensors By connecting a pressure sensor to the piping route of the fire extinguishing system and monitoring the pressure inside the piping, it is possible to know the status of sprinkler discharge, etc.

[0019] Furthermore, by using a repeater that measures 4-20 mA current, commercially available sensors that are compatible with the industry standard of 4-20 mA current measurement can be freely connected as terminal devices 20. Specific examples of such sensors include gas sensors and flame sensors.

[0020] It is also possible to use a transmitter that notifies the occurrence of a fire when a button is pressed as the terminal device 20. That is, the terminal device 20 used in the first embodiment transmits fire-related information that is used by the fire receiver 10 to determine whether or not a fire has occurred. The fire-related information is configured to include the various types of detection result information, measurement result information, operation result information, etc., as described above.

[0021] It is possible to display the detection results from the terminal device 20 not only in real time but also in time series data over a certain period as a trend history on the fire alarm receiver. By providing a function to display such trend data, it becomes possible to more quickly identify the cause of a false alarm.

[0022] For example, if the detection results of a pressure sensor are recorded as a trend history of time-series data, it will be possible to verify after the fact whether the pressure was released all at once or gradually.

[0023] When a gas sensor is used as the terminal device 20, the trend history of the gas concentration obtained as time-series data of the detection results can be used for post-event verification. Similarly, when a flame sensor is used as the terminal device 20, the trend history of the flame size obtained as time-series data of the detection results can be used for post-event verification.

[0024] Furthermore, when detecting air pressure using a differential heat detector as the terminal device 20, a sudden drop in air pressure may cause a false alarm. Even in such a case, the cause of the false fire alarm from the differential heat detector can be identified by referring to the trend history of air pressure obtained as time-series data of the detection results.

[0025] Figure 2 is a functional block diagram of the fire receiver 10 according to the first embodiment of the present invention. Note that the multiple terminal devices 20(1) to 20(4) shown in Figure 1 are simply shown as multiple terminal devices 20 in Figure 2. The multiple terminal devices 20 may be various sensors and measuring instruments as described above, and can be installed in a desired fire monitoring area.

[0026] 2 is configured to include the following mechanisms: a receiving unit 11, a memory control unit 12, a fire detection unit 13, a display control unit 14, an operation control unit 15, a memory unit 16, an alarm unit 17, a display unit 18, and an operation unit 19. The functions of the receiving unit 11, the memory control unit 12, the fire detection unit 13, the display control unit 14, and the operation control unit 15 can also be performed collectively by a single control unit.

[0027] The receiving unit 11 acquires the analog signals output from each terminal device 20 at a predetermined sampling interval, and then performs analog-to-digital conversion to generate a digital value. Note that the sampling interval does not need to be a common value for all terminal devices 20, and an appropriate value can be set individually depending on the physical quantity to be measured, the fire monitoring area, etc.

[0028] The memory control unit 12 sequentially stores the digital values ​​of the detection results by each terminal device 20, which are generated by the receiving unit 11, in the memory unit 16. At this time, the memory control unit 12 updates the stored data so that time-series data for a predetermined period of time remains in the memory unit 16. For example, for time-series data in which 10 pieces of data are obtained within a certain period of time, the memory control unit 12 performs an update process for the time-series data so that the most recent 10 pieces of data are stored in the memory unit 16. Therefore, by performing the sequential update process, the transition state of the most recent measurement value in the most recent predetermined period of time is stored in the memory unit 16.

[0029] The fire determination unit 13 determines whether or not a fire has occurred based on the latest time-series data or the latest real-time data stored in the memory unit 16. Furthermore, when the fire determination unit 13 determines that a fire has occurred, it can notify the fire occurrence status via the notification unit 17. Note that the determination process by this fire determination unit 13 is the same as that of the prior art, and a detailed description thereof will be omitted.

[0030] The display control unit 14 performs display control to display the detection results of two or more terminal devices on the same screen of the display unit 18 based on time-series data, which is the detection history of each terminal device, stored in the memory unit 16. The two or more terminal devices for simultaneously displaying data can be selected arbitrarily by the operator. For example, the display control unit 14 can display a list of all terminal devices on one screen and identify two or more terminal devices for simultaneously displaying data by reading a selection input by the operator. The selection input by the operator is performed via the operation unit 19, and the determination process is performed by the operation control unit 15, which will be described later.

[0031] Furthermore, the display control unit 14 performs display control to simultaneously display part or all of the time series data relating to two or more identified terminal devices on one screen of the display unit 18. For example, the display control unit 14 can display time series data over a certain period of time as a trend history, or can display only the latest real-time data.

[0032] When the fire detection unit 13 determines that a fire has occurred, the memory control unit 12 continues the update process while separately saving data for a predetermined period of time immediately before the time when it is determined that a fire has occurred. As a result, a trend history with the latest data as of the time when it is determined that a fire has occurred is stored in the memory unit 16 separately from data that has undergone normal update processing. As a result, by performing display control by the display control unit 14, it is possible to easily display time-series data with the latest data as of the time when it is determined that a fire has occurred, making it possible to quickly identify the cause of a false alarm.

[0033] Specifically, when a false alarm occurs, the display control unit 14 can simultaneously display two time series data consisting of the terminal device that issued the false alarm and another terminal device that is set in the same fire monitoring area as the terminal device.

[0034] The operation control unit 15 reads operation inputs input by an operator via the operation unit 19 and executes processing according to the operation input. In a fire alarm system such as that shown in Fig. 1, the operator is required to execute appropriate operations according to the event that has occurred, and to quickly issue a fire alert, give instructions for firefighting work, etc.

[0035] The first embodiment is provided with a configuration that can improve the operability of the operator. More specifically, the fire receiver according to the first embodiment is technically characterized in that it not only notifies the source of information, operation method, etc. by displaying text, but also notifies them by using illustrations in combination, thereby improving the operability. That is, the operation control unit 15 according to the first embodiment can display on the display unit 18 illustrations that improve the operability of the operator.

[0036] Therefore, in the following, the operability improvement function realized by the fire receiver of this embodiment 1 will be explained in detail based on the display content of specific characters and illustrations, with reference to screen examples 1 to 9.

[0046] That is, when the "?" mark at the end of third operation 123 is operated, operation control unit 15 displays an illustration and supplementary explanation corresponding to third operation 123 in illustration display area 120B. As a result, the operator can quickly perform third operation 123 by referring to the illustration and supplementary explanation displayed in illustration display area 120B. More specifically, by referring to the illustration and supplementary explanation, the operator can easily understand the location of the switch that stops the bell ringing in the library, and can quickly operate the switch that stops the bell ringing in the library.
