Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire alarm device for collecting smoke density data and temperature data from an analog sensor and displaying the history thereof.

[0002]

2. Description of the Related Art In general, a receiver collects smoke concentration data and temperature data from an analog smoke sensor and an analog heat sensor, respectively, by a polling method, and based on the collected data, whether or not there is a fire or a warning (pre-display) is displayed. Judge whether or not to perform an alarm. Further, the receiver can grasp the monitoring state by storing and displaying the history of the collected data before and after the alarm is issued by the sensor that issued the alarm, or by printing it out.

[0003]

However, there is a problem that the cause of non-fire cannot be sufficiently grasped only by the history of collected data before and after the alarm is issued by the issued sensor. In addition, when a history of a large amount of smoke density data and temperature data collected from the analog sensor is displayed or printed out, there is a problem that the monitoring state cannot be grasped because there is too much output data.

In view of the above conventional problems, the present invention provides a fire alarm device capable of efficiently and comprehensively grasping the reason for non-fire based on a large amount of data collected from a sensor. With the goal.

[0005]

In order to achieve the above object, the present invention stores, for each sensor, the measured values for a predetermined time in the past collected from an analog sensor and the maximum and minimum values of the day. The first storage means for storing the measured value from the time when the analog sensor is issued to the predetermined time, which is stored in the first storage means when the analog sensor issues an alarm. Second storage means for storing the daily maximum and minimum values of each sensor stored in the storage means, and the analog sensor measurement values and daily maximum values stored in the second storage means And output means for outputting the history of the minimum value in multiple windows.

Further, it is characterized in that the measured values stored in the first storage means are output on the same screen. Furthermore, when the analog sensor issues a report, the number of reports is saved at least by time, and a histogram of the number of reports for each sensor is output in a multi-window.

Further, when the analog sensor issues a report, the same content data of the sensor in the vicinity thereof is stored, and the data of the same content of the reported sensor and the sensor in the vicinity thereof are output in a multi-window. It is characterized by Further, the data having the same content includes the measured value for the past predetermined time stored in the first storage means and the measured value for the past predetermined time stored in the second storage means from the time of the alarm. Is characterized in that.

Further, the present invention is characterized in that the analog sensor is included in the data when the alarm is issued and the data is saved. Further, when the analog sensor is replaced, the measured values of the analog sensor stored in the first and second storage means are automatically deleted.

[0009]

According to the present invention, since the history of the measured values from the time when the analog sensor is issued until a predetermined time and the maximum and minimum values for each day are stored and output in a multi-window, a predetermined time before the notification is issued. It is possible to understand the history of the measured values of smoke concentration and temperature, and the range of the measured value of which day based on the history of the maximum and minimum values for each day. Therefore, the reason for non-fire can be grasped efficiently and comprehensively based on a large amount of data collected from the detectors.

Further, since the histogram of the number of times of reporting for each sensor is output in a multi-window, it is possible to grasp the monitoring status of the sensor that issued the alarm in chronological order such as hourly, daily and monthly. Therefore, it is possible to efficiently and comprehensively grasp the cause of non-fire based on the history of data collected from the sensors. In addition, since the data of the sensor that issued the alarm and the data of the sensors in the vicinity of the sensor are output in multiple windows, for example, when multiple sensors are installed in one room, the effect of the difference in the installation location of the sensors may be affected. You can figure it out.

Further, since the analog sensor is output including the data when the alarm is issued and the warning is displayed, the reason for non-fire can be grasped more comprehensively.
