[0006]
[Problems to be solved by the invention]
By the way, in the conventional automatic fire alarm system described above, especially in the initial stage of construction of the system (the initial stage of site adjustment), there are many sensors that are not connected to the sensor line. When proceeding for each sensor line, the fire receiver displays the trouble display of the disaster prevention sensor on the sensor line that has not yet been connected to that of the sensor line being worked on. Therefore, it took time to search for the necessary indications for disaster prevention sensors.
[0007]
The present invention has been made in view of such circumstances, and in a fire receiver,
It is an object of the present invention to provide an automatic fire alarm system capable of improving work efficiency without displaying troubles of a disaster prevention sensor on an unnecessary sensor line in proceeding with sensor connection work.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing an example of a main part configuration of an automatic fire alarm system according to the present invention, and FIG. 2 is a perspective view showing an example of an external appearance of a fire receiver.
This automatic fire alarm system is configured by deriving a plurality of sensor lines L from the fire receiver 1 and connecting a plurality of disaster prevention sensors S such as fire detectors to each of the sensor lines L. The fire receiver 1 includes a CPU and the like, and includes a signal processing unit 10 that controls each unit in the fire receiver 1, an operation unit 11 that includes various operation switches, a display unit 12 that includes a liquid crystal screen 12a, and the like. Polling between the address storage unit 13 and the disaster prevention sensor S via the sensor line L, and the transmission control unit 14 for monitoring the disaster prevention sensor S, and the sound for controlling the sound output from the speaker SP In addition to the output unit 15, the transmission line abnormality detection unit 16 (functions will be described later).
[0011]
For example, the address storage unit 13 is configured as shown in FIG. 3. For each sensor line L, the number of disaster prevention sensors S connected to the line L, the address information of the disaster prevention sensor S, and Is registered.
The fire receiver 1 outputs a fire alarm when a fire detector, which is one of the disaster prevention detectors S, outputs a fire alarm, displays the disaster prevention detector S on the display unit 12, and also gives an alarm from the speaker SP. A sound is output, and further, a district acoustic device (such as a bell) set in advance corresponding to a fire detector notifies the occurrence of a fire so that people in the building can evacuate quickly. At the same time, smoke control equipment (such as fire doors and smoke vents) adjacent to the fire detector that has been reported is linked and controlled to prevent the spread of fire and smoke.
[0012]
Furthermore, the fire receiver 1 is connected to a gas leak alarm device and various alarm devices in addition to the fire detector as the disaster prevention sensor S, and outputs an alarm when an abnormality such as a gas leak is detected. It has become.
In the fire receiver 1, such an operation state of the disaster prevention sensor S is displayed on the screen for each abnormality type. For example, electrical connection with the sensor line L of the disaster prevention sensor S is performed. If an abnormality of the disaster prevention sensor S occurs due to interruption or the like, and the reply to polling is not within a predetermined time, the transmission control unit 14 detects this and displays it on the liquid crystal screen 12a, for example, as shown in FIG. Although the trouble display is performed, when the electrical connection of all the disaster prevention sensors S of the sensor line L is interrupted, the transmission line abnormality detection unit 16 performs the following operation in response thereto.
[0013]
That is, the transmission line abnormality detection unit 16 always counts the number of disconnection detections of the disaster prevention sensor S by the transmission control unit 14, and the electrical connection of all the disaster prevention sensors S on the sensor line L is interrupted. Then, since the number of detections by the transmission control unit 14 matches the number of registered disaster prevention sensors per sensor line L in the address storage unit 13, the transmission line abnormality detection unit 16 detects this and displays on the display screen 12a. For example, trouble display as shown in FIG. 4 is performed.
[0014]
Such trouble display is made when the key 11d of the operation unit 11 is operated, the abnormality type (a) is displayed, and further, that all the sensors S of the sensor line L are disconnected. (A) is displayed.
In FIG. 4, each of 11 a to 11 d indicates a key operated to switch to each screen (fire screen, gas screen, alarm screen, trouble screen). Moreover, (c) indicates the number of displays for each type.
[0015]
When such a trouble display is being performed, when any abnormality of the disaster prevention sensor S is restored, for example, by any of the disaster prevention sensors S of the sensor line L being electrically connected, a response to polling is predetermined. Since it is done within the time, the transmission control unit 14 detects this, ends the trouble display in FIG. 4, and displays the trouble display as shown in FIG. 5 or FIG. 6, for example.
[0016]
In FIG. 5, a display (D) indicating the disaster prevention sensor S that is not electrically connected to the sensor line L is displayed (D), and in FIG. 6, a display (OFF) indicating that the sensor line L is being recovered from trouble. ) And a display (f) indicating the disaster prevention sensor S electrically connected to the sensor line L. Here, in FIG. 6, for the purpose of improving visibility, the “sensor connection” that is a normal system is displayed in red, for example, while the “transmission path abnormality being corrected” that is an abnormal system is displayed in green, for example. Alternatively, they may be color-coded from each other. Here, the fonts are different from each other in order to make it easy to identify the color coding.
[0017]
【The invention's effect】
As can be understood from the above description, in the automatic fire alarm system according to claim 1 of the present invention, the fire receiver detects an abnormality of all disaster prevention sensors connected to any one of the sensor lines. When this happens, the sensor line is displayed as a trouble. For example, in the initial stage of system construction (on-site adjustment initial stage), the connection work of the disaster prevention sensor is advanced for each sensor line. The trouble display of the disaster prevention sensor on the sensor line that has not been finished is not mixed with that of the sensor line being worked on, and the work efficiency is greatly improved.
[0018]
In the automatic fire alarm system according to claim 2, the fire receiver detects an abnormality of all the disaster prevention sensors connected to any one of the sensor lines, and displays a trouble on the sensor line. If any of the disaster prevention sensors connected to the sensor line recovers, the trouble display for that sensor line is terminated. After that, the sensor line is not electrically connected. If there is no trouble display for the disaster prevention sensor, it is very useful to proceed with the connection work of the disaster prevention sensor for each sensor line.
[0019]
In the automatic fire alarm system according to claim 3, since the fire receiver displays the troubles of the remaining disaster prevention sensors that have not recovered from the trouble after the trouble display of the sensor line is finished, In order to proceed with the connection work for each sensor line, it is useful to be able to easily check disaster prevention sensors that have not recovered from abnormalities.
In the automatic fire alarm system according to claim 4, after the fire receiver has finished displaying the trouble of the sensor line, the fire receiver displays that the trouble of the sensor line is being recovered and the disaster detection has been recovered from the abnormality. When the abnormality of all disaster prevention sensors connected to the sensor line is restored, these indications are deleted, so the work efficiency of the disaster prevention sensor is greatly improved. To do.
[0020]
In the automatic fire alarm system according to claim 5, the fire receiver color-codes the display indicating that the sensor line is in trouble recovery and the display indicating the disaster recovery sensor whose abnormality has been recovered. It becomes easy to distinguish between normal and abnormal systems.
