[0013] Hereinafter, preferred embodiments of the fire alarm receiver among the fire-related information display devices of the present invention will be described with reference to the drawings.

[0014] Embodiment 1. FIG. 1 is an overall configuration diagram of a fire alarm facility according to Embodiment 1 of the present invention. The fire alarm facility shown in FIG. 1 includes 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. Also, 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 number of terminal devices 20 and repeaters 30 is not limited to the example of FIG. 1.

[0015] The fire alarm facility shown in FIG. 1 is a so-called R-type fire alarm facility. Therefore, the four terminal devices 20(1) to 20(4) output measurement results, detection results, etc. as analog signals, and the fire receiver 10 determines the presence or absence of a fire based on the reception results of these analog signals.

[0016] Also, representative examples of the terminal device 20 include the following types of photoelectric analog sensors and thermal analog sensors. · Photoelectric analog sensor In a fire monitoring area, a smoke sensor that can detect the occurrence of smoke as an analog value when the light irradiated from the light projecting unit is attenuated by the influence of smoke and received by the light receiving unit, or a smoke sensor that can detect the occurrence of smoke as an analog value when the light receiving unit receives the scattered light scattered by the smoke particles from the light projecting unit. · Thermal analog sensor It corresponds to a heat sensor that can detect heat as an analog value in a fire monitoring area.

[0017] Also, as a terminal device that can measure the surrounding situation in a fire monitoring area, a measuring instrument that measures temperature, atmospheric pressure, humidity, CO gas, etc. can also be used.

[0018] Furthermore, the following various sensors can also be used as terminal devices. · Pressure sensor By connecting pressure sensors in the piping routes of the fire extinguishing system and monitoring the pressure inside the pipes, it is possible to know the status of sprinkler deployment and other related information.

[0019] Furthermore, by using a relay device that measures currents between 4 and 20 mA, commercially available sensors that support the industry standard of 4-20 mA current measurement can be freely connected as terminal devices 20. Specific examples of these sensors include gas sensors and flame sensors.

[0020] Furthermore, a transmitter that notifies the system of a fire when a button is pressed can also be used as the terminal device 20. In other words, the terminal device 20 used in this embodiment 1 transmits fire-related information used by the fire receiver 10 to determine whether or not a fire has occurred. The fire-related information consists of various types of detection result information, measurement result information, operation result information, etc., as described above.

[0021] Furthermore, the detection results from terminal device 20 could be displayed on the fire alarm receiver not only as real-time values, but also as time-series data over a certain period as a trend history. By providing a function to display such trend data, it would be possible to pinpoint the cause of false alarms more quickly.

[0022] For example, if the detection results of a pressure sensor are recorded as a trend history of time-series data, it becomes possible to retrospectively verify phenomena such as 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 gas concentration obtained as time-series data of the detection results can be used for retrospective verification. Similarly, when a flame sensor is used as the terminal device 20, the trend history of flame size obtained as time-series data of the detection results can be used for retrospective verification.

[0024] Furthermore, when a differential heat detector is used as the terminal device 20 to detect atmospheric pressure, a sudden drop in atmospheric pressure may cause a false alarm. In such cases, the cause of the false alarm by the differential heat detector can be investigated by referring to the trend history of atmospheric pressure obtained as time-series data of the detection results.

[0025] Figure 2 is a functional block diagram of a fire alarm receiver 10 according to Embodiment 1 of the present invention. In Figure 1, the multiple terminal devices 20(1) to 20(4) are shown simply as multiple terminal devices 20 in Figure 2. Various detectors and measuring instruments as described above can be considered as multiple terminal devices 20, and they can be installed in a desired fire monitoring area.

[0026] The fire alarm receiver 10 shown in Figure 2 is composed of 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. Note that the functions of the receiving unit 11, memory control unit 12, fire detection unit 13, display control unit 14, and 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 digital values. The sampling interval does not need to be the same for all terminal devices 20; appropriate values ​​can be set individually according to 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 from each terminal device 20, which are generated by the receiving unit 11, into the memory unit 16. At this time, the memory control unit 12 updates the stored data so that a predetermined amount of time-series data remains in the memory unit 16. For example, for time-series data in which 10 data points are obtained within a certain period of time, the memory control unit 12 updates the time-series data so that the most recent 10 data points are stored in the memory unit 16. Therefore, as the sequential update process is performed, the memory unit 16 stores the transition state of the latest measured values ​​for the most recent predetermined period.

[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, if the fire determination unit 13 determines that a fire has occurred, it can notify the fire situation via the notification unit 17. Note that the determination process by this fire determination unit 13 is the same as in the prior art, and a detailed explanation is 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 the time-series data, which is the detection history of each terminal device, stored in the storage unit 16. The two or more terminal devices for simultaneous data display can be arbitrarily selected by the operator. For example, the display control unit 14 can identify two or more terminal devices for simultaneous data display by displaying all terminal devices in a list on one screen and reading the operator's selection input. The operator's selection input is made via the operation unit 19, and the decision processing 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 some or all of the time-series data relating to two or more specified terminal devices on a single screen of the display unit 18. For example, the display control unit 14 can display time-series data over a certain period as a trend history, or it can display only the latest real-time data.

[0032] Furthermore, if the fire detection unit 13 determines that a fire has occurred, the memory control unit 12 can continue the update process while separately saving data for a predetermined time immediately preceding the time the fire was determined to have occurred. As a result, the memory unit 16 maintains a trend history with the time the fire was determined to have occurred as the latest data, separate from the normally updated data. Consequently, by controlling the display using the display control unit 14, the time-series data with the time the fire was determined to have occurred as the latest data can be easily displayed, making it possible to quickly identify the cause of a false alarm.

[0033] Specifically, in the event of a false alarm, the display control unit 14 can simultaneously display two time-series data sets: one from the terminal device that triggered the false alarm, and another from a terminal device set in the same fire monitoring area as that terminal device.

[0034] The operation control unit 15 reads the operation inputs entered by the operator via the operation unit 19 and executes processing according to the operation inputs. In a fire alarm system like the one shown in Figure 1, the operator is required to perform appropriate operations in response to the event that occurs and to quickly issue fire information, give instructions for firefighting, etc.

[0035] This first embodiment includes a configuration that can improve operator operability. More specifically, the fire alarm receiver according to this first embodiment is characterized by its technical features, which include not only notifying the information source, operating method, etc., by text display, but also by using illustrations in conjunction with the text display to improve operability. In other words, the operation control unit 15 according to this first embodiment can display illustrations that improve operator operability on the display unit 18.

[0036] Therefore, the following will explain in detail the operability improvement function realized by the fire alarm receiver according to this embodiment 1, based on the specific text and illustrations displayed, with reference to screen examples 1 to 9.

[0037] <Screen Example 1: Operation Guidance Regarding Fire Detection Switch> Figure 3 is a diagram showing an example screen 1 displaying operation guidance for a fire detection switch in Embodiment 1 of the present invention.

[0038] The screen display area in Figure 3 is broadly divided into the upper information display area 110 and the lower operation display area 120. The operation display area 120 also includes the text display area 120A on the left and the illustration display area 120B on the right. Furthermore, the text display area 120A shows an example where the first operation 121 to the seventh operation 127 are displayed as text.

Furthermore, in this example screen 3, when the operator performs the third operation 123, "Stop the bell sound in the building," pressing the "?" mark at the end displays an illustration and supplementary explanation corresponding to the third operation 123 in the illustration display area 120B.

[0046] In other words, when the "?" mark at the end of the third operation 123 is pressed, the operation control unit 15 displays an illustration and supplementary explanation corresponding to the third operation 123 in the illustration display area 120B. As a result, the operator can quickly perform the third operation 123 by referring to the illustration and supplementary explanation displayed in the illustration display area 120B. More specifically, by referring to the illustration and supplementary explanation, the operator can easily understand the location of the switch to stop the bell sound in the building and quickly operate the switch to stop the bell sound in the building.

Furthermore, in this example screen 4, when the operator performs the fourth operation 124, "reset the transmitter," pressing the "?" mark at the end displays an illustration and supplementary explanation corresponding to the fourth operation 124 in the illustration display area 120B.

[0049] In other words, when the "?" mark at the end of the fourth operation 124 is pressed, the operation control unit 15 displays an illustration and supplementary explanation corresponding to the fourth operation 124 in the illustration display area 120B. As a result, the operator can quickly perform the fourth operation 124 by referring to the illustration and supplementary explanation displayed in the illustration display area 120B. More specifically, by referring to the illustration and supplementary explanation, the operator can easily understand the operation required to reset the transmitter and quickly perform the transmitter recovery operation.

[0050] <Screen Example 5: Operation Guidance for the Recovery Switch> Figure 7 shows an example screen 5 displaying operation guidance for the recovery switch in Embodiment 1 of the present invention. The configuration of the screen display area in Figure 7 is the same as that in Figures 3 to 6.
