Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display device for a disaster prevention system which, when a sensor arranged in a monitoring area of the disaster prevention system detects an abnormality, displays an abnormality notification corresponding to the abnormality detection signal in a sentence within a predetermined number of characters.

[0002]

[Prior Art]

 Conventionally, in the display device of such a disaster prevention system, the content of the abnormality notification is displayed at one end of the operation panel of the centralized monitoring device installed in the central monitoring room or the like, as shown in FIG. A display indicator for displaying is provided. Furthermore, this display has 16 light-emitting diodes arranged side by side in a matrix, and each light-emitting diode is turned on to display one character. 16 light-emitting devices are arranged side by side. It is configured to display the letters of the notification text on the light emitter.

By the way, when, for example, various sensors simultaneously detect fires, gas leaks, and other abnormalities at a plurality of locations, the centralized monitoring device stores the abnormality detection data from these sensors in a memory, and further, , Priority is given to the display to display the anomaly notification concerning the most dangerous of the detected anomalies. Also, if the monitor wants to know about other detected items, he or she can enter a predetermined display command via an input device such as a keyboard, and the centralized monitoring device will store the abnormality detection data stored in the memory in the order of storage. By displaying the error notification contents corresponding to the error detection data in order on the above-mentioned display unit, it is possible to display not only the error notification related to the highest risk, but also all other error notification contents. You can

In addition, in order to display the item having the highest risk level among the detected anomalies, that is, the anomaly report having the highest priority, separately from other anomaly reports, as shown in FIG. When displaying the anomaly notification with the highest priority, a special identification symbol, etc. is displayed on the display digit located on the leftmost side, followed by the text of the anomaly notification. Also, as shown in Fig. 5, a light-emitting lamp is separately installed outside the 16-digit display, and this light-emitting lamp is turned on only while displaying the highest priority abnormality notification. In some cases, the priority of the abnormality notification can be identified by turning off the light-emitting lamp when a low abnormality notification is displayed.

[0005]

[Problems to be solved by the device]

 However, in such a conventional display device of the disaster prevention system, since the number of characters that can be displayed is limited, it is necessary to make a report in a concise and clear sentence. In the case of a display device in which the display digit on the left side is applied to display the priority, it is necessary to display the notification text in the display digit with a small remaining amount, so the degree of freedom in selecting the content of the notification is narrowed. This may lead to a problem that effective expression cannot be performed. On the other hand, if the indicator lamps for indicating the priority are separately arranged as shown in FIG. 5, the cost may increase. Cause problems.

The present invention has been made in view of such conventional problems, and all display digits that can be displayed can be used for displaying a notification text, and at the same time, a priority display can be performed. It is an object to provide a display device of a disaster prevention system that enables it.

[0007]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention receives anomaly detection signals from various sensors installed in a plurality of monitoring areas and predetermines an anomaly occurrence notification text corresponding to the anomaly detection signals. In a display device of a disaster prevention system that displays a display on a display device that can display within the range of the number of characters, reference text data that corresponds to each sensor is stored in advance for the text of the notification text corresponding to the monitoring content of each sensor. When the storage unit and the abnormality detection signal are received, the report text data corresponding to the monitoring content of the sensor that has output the abnormality signal is retrieved from the reference information storage unit and displayed on the display unit. Upon receiving a type of abnormality detection signal, based on the data for report text of the monitoring content with the highest priority among the monitoring content of the multiple sensors that output these abnormality signals. And the configuration and a control section for inverting displayed on the display unit.

[0008]

[Action]

 According to the display device of the disaster prevention system of the present invention having such a configuration, even if all the display digits of the display device are applied to the display of the notification text, the notification content having the highest priority can be identified by the reverse display. Therefore, a reasonable display means can be provided.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. First, explaining the configuration in FIG. 1, a plurality of sensor groups 1 and receivers 2 installed in each monitoring area are connected by a transmission system such as a so-called polling system, and further, in a central monitoring room. The display device 3 in the installed centralized monitoring device and the receiver 2 are connected via the input unit 4.

That is, the input unit 4 has a function of an input / output interface for receiving an abnormality detection signal transferred from each sensor via the receiver 2, and a central control unit having a calculation function such as a microcomputer. The abnormality detection signal is transferred to 5. The reference information storage unit 6 is composed of a read-only memory (ROM), and as shown in FIG. 2, the message text data representing the monitoring contents of each sensor is stored in advance as record data corresponding to each sensor. ing. Each record data consists of a priority setting part with a specified number of bits and a character data part with a specified number of bytes. The priority setting part is composed of numerical data indicating a highly dangerous order, and the character data part is a notification. It consists of character data for each character that is the content of the display.

The display control unit 7 controls the display device 9 to display the data stored in the display data storage unit 8 in accordance with a command from the central control unit 5. That is, when the central control unit 5 receives the abnormality detection signal via the input unit 4, one message text data corresponding to this abnormality detection signal is read from the reference information storage unit 6 and displayed as a random access memory. The notification text data is stored in the data storage unit 8, and the display control unit 7 transfers the notification text data indicated by the central control unit 5 from the display data storage unit 8 to the display unit 9 to generate the notification text data. Display the corresponding report text. In addition, the display 9 has 16 light emitting diodes arranged in a matrix in the vertical and horizontal directions and lights any one of the light emitting diodes to display one character, and 16 light emitters are arranged side by side. By displaying the characters based on each character data of the message text data, the message text is displayed.

Further, when the central control unit 5 receives the abnormality detection signals from the plurality of sensors, each time the central control unit 5 receives the respective signals and stores the report text data in the display data storage unit 8, the priority is given to the priority control unit 5. By rearranging the arrangement of the storage areas in the order of the high-priority report text data based on the data of the priority setting section, the highest-priority report text data is always stored in the top storage area of the display data storage section 8. Let

Further, the notification text data stored in the top storage area of the display data storage section 8 is converted into data that can be reversed and stored. That is, the character data in the normal format stored in the storage area other than the head storage area is the normal rotation that is associated so that the characters are expressed by the lighting part of the light emitting diode of each surface light and the surroundings are turned off. In contrast to the display data format, the data that can be displayed in reverse is a data format in which the character part is turned off and the surrounding area is turned on to display it in reverse.

The operation unit 10 is composed of a keyboard and switches for a supervisor or the like to specify a desired display to the central control unit 5. For example, when a notification display of the highest priority is designated, the central control unit 5 Instructs the display control unit 7 to transfer the character data in the character data portion of the record data stored in the first storage area in the display data storage unit 8 to the display unit 9 or to use a predetermined switch. When is operated, the central control unit 5 instructs the display control unit 7 each time to operate, and the character data of the character data part of the record data stored in the earliest storage area in the display data storage unit 8 By sequentially transferring the information to the display 9, processing such as changing the notification display is performed in sequence.

Next, the operation of the embodiment having such a configuration will be described with reference to the flowchart of FIG. Note that the display control unit 7 transfers the data in the display data storage unit 8 to the display unit 9 at a predetermined cycle by direct memory access (DMA) transfer based on a command from the central control unit 5. And, the display is realized. First, in step S1, the central control unit 5 determines whether or not an abnormality detection signal is received from various sensors via the input unit 4, and if it is determined that the abnormality detection signal is received, the process proceeds to step S2, and a new Only when the abnormality detection signal is received, the process proceeds to step S3. That is, in order to avoid performing the same process every time the same abnormal detection signal is continuously received from the same sensor, the process of step S3 is performed only for the first received abnormal detection signal. I am going to do it.

In step S3, the notification text data corresponding to the abnormality detection signal is read from the reference information storage unit 6, and in step S4, when the abnormality detection signal is received for the first time after the monitoring is started, The report text data is stored in the first storage area of the display data storage unit 8, and in the case of the abnormality detection signal received after the second, the first storage area in the free storage area of the display data storage unit 8 is stored. Store.

Further, when it is determined in step S4 that the signal is the first abnormality detection signal, the process proceeds to step S8, and the notification display data at the head of the display data storage unit 8 is converted into data that can be reversed and re-displayed. Store. As a result, the display 9 will reversely display the message corresponding to the first detected abnormality detection signal. On the other hand, in step S4, when it is judged that it is the second or later received abnormality detection signal, the process proceeds to step S5, and the data of the priority setting part of each record data in the display data storage part 8 is compared. Then, the notification display data with the highest priority is rearranged in order.

Next, in step S6, if there is no change in the highest priority notification display data even after the rearrangement processing in step S5, the process returns to step S1 and the new notification display data becomes the highest priority. If the notification display data is No., the process proceeds to step S7. In step S7, the earliest notification display data in the display data storage unit 8 is converted into inverted display data and stored again, and other notification display data is restored to normal normal display data. Then, when the series of processes is completed, the process returns to step S1 and the process for the next abnormality detection signal is repeated.

As described above, according to this embodiment, when a high-priority notification display is performed, the display is reversed, so that the display within a predetermined number of characters is rationalized. be able to.
