Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abnormality monitoring system for monitoring an abnormality such as a fire alarm system or a crime prevention system.

[0002]

2. Description of the Related Art Conventionally, a fire alarm as disclosed in Japanese Patent Laid-Open No. 64-50194 has been known. When an abnormality occurs, this fire alarm records the type of the abnormality, the location where the abnormality occurred, and the time when the abnormality occurred in the abnormality record buffer, and even after the abnormality is recovered, the content recorded in the abnormality record buffer is displayed. By doing so, it is possible to know what kind of abnormality, where and when it occurred in the past.

[0003]

By the way, in the above-mentioned conventional fire alarm, the number of types of abnormalities recorded in the abnormality recording buffer is abnormal due to an alarm or abnormal without alarm (device failure ( Mainly 2)
It is limited to the type, and if it is an alarm abnormality, whether it is a true abnormality (for example, an actual fire),
Or it was not designed to categorize whether it was due to a false anomaly (eg non-fire such as heating heat or cigarette smoke). In general, in the abnormality monitoring system, including the above-mentioned fire alarm, this is due to whether the cause of the abnormality is due to a true abnormality (eg, actual fire) or a false abnormality (eg, non-fire). Is due to the fact that the system cannot determine it. Therefore, conventionally, when an alarm is received, the operator (for example, the system administrator) usually confirms the location of the alarm and determines whether this alarm is due to a true abnormality or a false abnormality. When I wanted to record this fact, I wrote down in the daily report that the cause was cigarette smoke. In addition, by writing it down in a daily report, etc., when maintenance and inspection of this system is done,
The cause of the false abnormality can be analyzed and appropriate measures can be taken against the alarm generated by the false abnormality.

However, the work of writing down the type of information generation cause in the daily report etc. is all left to the system administrator, and the system administrator neglects to write it down in the daily report etc., or this daily report etc. If it is lost or is not delivered to the maintenance inspector, there is a problem in that accurate information is not delivered to the maintenance inspector and the experience so far cannot be effectively utilized for appropriate measures thereafter.

In the present invention, when an abnormality occurs, the cause of the abnormality is recorded in a reliable and clear manner, and appropriate measures can be easily and effectively performed based on this information at the time of maintenance and inspection, for example. It is an object of the present invention to provide an abnormality monitoring system capable of doing so.

[0006]

In order to achieve the above object, the invention according to claim 1 is characterized in that a factor input means capable of inputting a factor causing an abnormality and the occurrence of the abnormality are detected.
When the cause of the abnormality is input from the factor input means,
And a recording unit for recording the cause of the abnormality as history information. As a result, the cause of the abnormality can be input to the system and recorded and retained as history information in the system, giving accurate information to the operator at the time of maintenance and inspection, and taking appropriate experience from the experience so far. Can be effectively utilized. Also,
The invention according to claim 2 is characterized in that the cause of the abnormality is classified and input. This allows the operator to categorize and input the cause of anomaly, which facilitates the task of inputting the factor. Moreover, during maintenance and inspection, the categorized and recorded history information of the cause of anomaly is recorded. Based on the above, it is possible to easily and clearly grasp the cause of the abnormality, and it is possible to easily take appropriate measures.

Further, the invention according to claim 3 is further provided with a recovery means for performing a system recovery process after the occurrence of the abnormality, and the recovery means is inputted in response to the occurrence of the abnormality. It is characterized in that the recovery process is performed on condition that the cause of the abnormal occurrence should be input from the factor input means. As a result, if the cause of the abnormality that should be input is not input, the recovery process cannot be performed and the alarm will continue to be output, so after confirming the abnormality, the cause of the abnormality is reported to the operator. It is possible to input surely.

Further, according to the invention of claim 4, the system can be switched to a test recovery mode for performing maintenance and inspection, and in the test recovery mode, when an abnormality is detected, The recording means is characterized by uniquely assigning the content of maintenance and inspection as a cause of the abnormality and recording the content. As a result, it is possible to prevent the input procedure at the time of maintenance / inspection from becoming complicated and to clarify that the input is artificial due to maintenance / inspection.

And a return data creation circuit 24 that creates return data based on the monitoring signal of FIG.

FIG. 4 shows the display / operation unit 16 of the receiver 1.
It is a figure showing an example of composition, and this display and operation part 16 is main acoustic device 31 which sounds when abnormality, such as a fire, is detected.
And a fire representative lamp 32 that lights up when an abnormality such as a fire is detected, and a district display window 33 that displays the number (more specifically, the line number of the district) of the repeater that detected the abnormality such as a fire.
The display panel 34 for giving a message to the operator and displaying guidance for supporting the operator's work, the fire representative lamp 32, the district display window 33 are turned off, and the main acoustic device 31 and the district acoustic device 5 are A recovery switch 35 for performing a recovery process such as stopping the ringing,
For example, a keyboard 36 for inputting the cause of abnormality by categorizing it by a code number, and a history output switch 37 for outputting the history of the cause of abnormality recorded in the history event buffer 18 of the storage device 11. When,
It has a mode changeover switch 38 for putting the system into a test recovery mode for maintenance and inspection.

When an abnormality such as a fire is detected, the display panel 34 prompts the user to input the cause of the abnormality from the keyboard 36. For example, the guidance as shown in FIG. 5 is displayed. It has become. That is,
In the example of FIG. 5, “actual fire, small fire” is displayed in correspondence with the code number “01”, and “heating heat, cooking heat, boiler heat” is displayed in correspondence with the code number “02”. It is displayed and "cigarette smoke, cooking smoke" is displayed in association with the code number "03".

Further, the central processing unit 10 of the receiver 1 is configured as follows in correspondence with the above-mentioned configuration of the display / operation unit 16. That is, the central processing unit 10 detects an abnormality such as a fire in a certain sensor, and information related to this (for example, the line number of the area where the abnormality is detected and the type of the abnormality (preliminary alarm, fire alarm, control alarm, etc.) ) Etc.) is notified from the repeater 2, the main sound device 31 and the district sound device 5 are sounded, the fire representative lamp 32 is turned on, and the district display window 33 detects that an abnormality is detected. The line number is displayed. Further, the time of occurrence of the abnormality obtained from the clock unit 17 and the place of occurrence of the abnormality obtained from the repeater 2 as described above (specified by the line number of the district) are recorded in the history event buffer 18, When the cause of the abnormality is input from the keyboard 36 of the display / operation unit 16, the cause of the abnormality is associated with the previously recorded time and place of occurrence of the abnormality, and the history event buffer is stored as history information. 18
It is designed to be recorded in. It should be noted that, when no abnormality has occurred and the detection of the abnormality has not been notified from the relay device 2, even if the cause of the abnormality has been input from the keyboard 36, it is not accepted. In addition, the cause of the abnormality can be entered only once. Therefore, after inputting the cause of the abnormality once, the cause of the abnormality continues to be input except for the case of correction input after erroneous input. The central processing unit 10 does not accept the factor after the second time even if is input.

In addition, in the central processing unit 10, in principle, when the restoration switch 35 is operated while the main sound device 31 and the district sound device 5 are ringing, the abnormality detection display as described above is made. , Fire representative light 32, district display window 33
Is turned off, and the ringing of the main audio device 31 and the district audio device 5 is stopped. However, in the present embodiment, the cause of the abnormality that should be input is input from the keyboard 36 by turning off the fire representative lamp 32, the district display window 33, and stopping the ringing of the main audio device 31 and the district audio device 5. It is supposed to be performed on the condition that it was done. Therefore, even if the recovery switch 35 is operated, recovery processing is not performed unless the cause of the abnormality that should be input is input from the keyboard 36, and an alarm is output, that is, the fire representative light 32 and the area display window 33 are displayed. The ringing from the main audio device 31 and the district audio device 5 is continued.

Further, when the mode changeover switch 38 of the display / operation unit 16 is switched to the test recovery mode, the central processing unit 10 receives an input from the keyboard 36 as a cause of the abnormality when the abnormality occurs. Independently, the contents of the maintenance inspection are uniquely assigned and recorded. Therefore, in this case, even if the cause of the abnormality is input from the keyboard 36, it is not accepted, and the recovery switch 35 is automatically operated if the factor input from the keyboard 36 is not a condition. It is designed to perform recovery processing.

Next, the processing operation of the abnormality monitoring system having such a configuration will be described with reference to the flowchart of FIG.
In the following, it is assumed that n repeaters are provided,
It is assumed that # 1, # 2, ..., #n are set as the unique addresses in the address setting unit 21 of each repeater 2. At the time of initial setting of this system, the central processing unit 10 of the receiver 1 initializes the flag F for determining whether or not the cause of the abnormality has been input at the time of occurrence of the abnormality to “0”, and also the storage device. The history event buffer 11 and the like are initialized (step S1). Next, the counter i for identifying the repeater 2 is initialized to "1" (step S2).

Thereafter, the central processing unit 10 calls the repeater 2 (#i) corresponding to the counter i and fetches the information from this repeater 2 (step S3). That is,
The central processing unit 10 first sends a call signal composed of an address section and a command section to each repeater 2.
At this time, the address “#i” corresponding to the counter i is set in the address section. A return data collection command is usually set in the command section. Therefore, the call signal causes the repeater 2 having the unique address #i to be called. In the repeater 2 (#i), the command identifying circuit 23 identifies the command as the return data collection, and the district circuit 22 And an abnormal occurrence state such as a fire detected by the acoustic control circuit 25 in a known manner,
Alternatively, data indicating a failure state or a normal state of a device or a line is created by a return data creation circuit 24 in a known manner and returned to the central processing unit 10 of the receiver 1.
For example, an abnormal occurrence state such as a fire is simply detected according to the operating state of the district circuit 22, or the sensor is forcibly restored once, and the time is determined again (accumulation time).
It is detected when the district circuit 22 is restarted.

Upon receiving the return data from the repeater (#i), the central processing unit 10 uses the return data from the repeater (#i) to establish a line in the area of the repeater (#i). It is determined whether an abnormality such as a fire has occurred, the line in this area is in a failure state, or the line in this area is in a normal state (step S4).

As a result, when it is determined that an abnormality such as a fire has occurred, or when it is determined that a device, a line, or the like is in a failure state, first, the abnormality or failure that is obtained as information from the repeater (#i) is detected. The occurrence place (for example, the line number of the district) and the occurrence time obtained from the clock unit 17 are recorded in the history event buffer 18 (step S
5). Next, if an abnormality such as a fire has occurred (step S6), the fire representative lamp 32 of the display / operation unit 16 is turned on, and the line number of the district corresponding to this repeater (#i) is changed to the district. The main sound device 31 and the district sound device 5 at the place where this abnormality occurs are sounded while being displayed on the display window 33 (step S7). That is, an alarm is output. At this time, the central processing unit 10 determines whether the processing mode is switched to the test recovery mode (step S8), and when the test recovery mode is set,
The history event buffer 18 of the storage device 11 indicates that the cause of the abnormality is maintenance inspection in association with the location and time of occurrence of the abnormality recorded in step S5.
(Step S9).

If it is determined in step S6 that an abnormality such as a fire has not occurred, but that a device, a line, or the like has failed, for example, the district display window 33 displays the district corresponding to the repeater (#i). The line number of the district display window 33
In the history event buffer 18 of the storage device 11 in association with the location and time of occurrence of the failure recorded in step S5. (Step S11).

In step S8, when the processing mode is not the old mode after the test, it is judged that the abnormality has not occurred during maintenance but the actual operation, and the flag F is set to "1". Set (Step S1
0).

In this way, after it is judged in step S4 that an abnormality has occurred, or it has been judged as a failure and predetermined processing has been performed, or after it has been judged in step S4 that it is in a normal state, this central The processing device 10 performs an input process (step S12). That is, the central processing unit 10
Is the keyboard 3 of the display / operation unit 16 as described later.
6, one of the recovery switch 35 and the history output switch 37 is operated to determine whether or not there is any input, and when there is an input, the process corresponding to that input is performed. It should be noted that this input processing is performed as input interrupt processing in the central processing unit 10.

When the input process of step S12 is completed,
The central processing unit 10 increments the counter i by "1" (step S13), and determines whether i becomes larger than n (step S14). When i is not larger than n, the process returns to step S3 again, the next repeater having the one larger unique address is monitored in the same manner as above, its storage is identified, and a predetermined value is determined according to the state. Perform processing.

In this way, the central processing unit 10
In steps of "1", and steps S1 to S
The process of 14 is repeated. That is, the repeater 2 (#
1 to #n) are sequentially monitored, and each time, predetermined processing is performed according to the state. When i becomes larger than n in step S14, the process returns to step S2 again, and the same process is repeated from the repeater 2 (# 1).

In the above series of repetitive processing, it is judged that an abnormality such as a fire has occurred in the line of the repeater (#i) based on the return data from the repeater (#i) of the central processing unit 10. In step S7, the fire representative lamp 32 of the display / operation unit 16 is turned on, and the relay device (#
When the area line number of i) is displayed on the area display window 33 and the main audio device 31 and the area audio device 5 are activated, that is, when an alarm is issued, the operator (system administrator)
Usually goes straight to the site where the detector for which an abnormality has been detected is installed and immediately confirms the cause of the abnormality. As described above, there are two causes of abnormalities, one is due to a true abnormality (actual fire) and the other is due to a false abnormality (non-fire such as cigarette smoke). If so, the operator would normally call the transmitter 4 near this site.
To control the fire or to return to the disaster prevention center for proper fire suppression control, or to inform the unspecified number of people in the building that the fire is occurring, the district audio system at the place where the fire occurred Not only will sound all district audio equipment. On the other hand, as a result of the above confirmation, if it is a false abnormality, the operator normally turns off the fire representative lamp 32, the district display window 33, the main sound device 31, the district sound device 5.
A so-called restoration process is performed to stop the ringing of the.

By the way, in the abnormality monitoring system of the present embodiment, when the above-mentioned abnormality (including both true abnormality and false abnormality) occurs, this maintenance operation is performed so that maintenance and inspection can be easily performed later. It is intended to let the operator input the cause of the abnormality, capture it in the system, and record it.
Therefore, in the system of FIG. 1, when the operator goes straight to the site and confirms what is the cause of the abnormality,
The operator follows the display guidance as shown in FIG.
It is possible to classify and enter as a code number from. For example, as a result of the confirmation, if it is a real fire, "01" can be input, and if it is caused by cigarette smoke, "03" can be input.

FIG. 7 is a flow chart showing details of the input processing in step S11. Referring to FIG. 7, in this input process, first, the keyboard 3 of the display / operation unit 16 is
6, it is determined whether there is an input from any one of the recovery switch 35 and the history output switch 37 (step T).
1). When there is an input from any of the above, it is determined whether or not this input is an input of the cause of the abnormality from the keyboard 36 (step T2). When this input is the input of the cause of the abnormality from the keyboard 36, it is determined whether or not the flag F is "1" (step T3). When the flag F is "1", the input is made. The cause of occurrence of the abnormality (for example, its code number) is recorded in the history event buffer 18 in association with the location and time of occurrence of the abnormality already recorded in the history event buffer 18 (step T4). When this recording is completed, the flag F is cleared to "0" (step T5).

On the other hand, even if it is determined in step T2 that the cause of the abnormality has been input, in step T3, when the flag F is not "1" (when the flag F is "0"), It is judged that the error has not been received from the repeater 2 or that the factor has already been input and that this factor has been input for the second time or later. Do not accept this input unless

If it is determined in step T2 that the cause of the abnormality has not been input, it is then determined whether this input is due to the operation of the recovery switch 35 (step T6). If the input is made by operating the recovery switch 35, it is first checked whether or not the flag F is "1" (step T7). When the flag F is “1”, the cause of the abnormality that should be input has not been input from the keyboard 36 yet. In this case, the operator is prompted to input the cause of the abnormality, so the recovery process is performed. Do not do.

On the other hand, in step T7, when the flag F is not "1" (when the flag F is "0"), the cause of the abnormality is already input from the keyboard 36 or the mode is restored from the test. The history event buffer 18 is uniquely assigned with the content indicating that it is in maintenance mode as the cause of the abnormality in the mode.
It is determined that the history event buffer 18 has already been recorded in the history event buffer 18 or the failure of the equipment or the line and the fact that the failure is the cause of the abnormality are recorded in the history event buffer 18, and the recovery process is performed ( Step T8). That is, the fire representative light 32 and the district display window 33 are turned off,
Further, the ringing of the main audio device 31 and the district audio device 5 is stopped, and the output of the alarm is stopped.

If it is determined in step T2 or step T6 that the input is not from the keyboard 36 or the operation of the recovery switch 35,
It is determined whether or not this input is due to the operation of the history output switch 37 (step T9). As a result, when the input is made by operating the history output switch 37, the history information recorded in the history event buffer 18 is output to a printer or a display, or is transmitted and output by serial communication (step T1).
0).

As described above, in this embodiment, when the operator (for example, the system administrator) confirms the cause of the abnormality at the site of the abnormality, the operator can identify the cause of the abnormality from the keyboard 36, for example, the code number. Can be categorized and entered, and when the cause of the abnormality is categorized and entered, the cause of the abnormality (for example, its code number) is associated with the time and place of occurrence of the abnormality. It can be recorded as history information in the history event buffer 18 of the storage device 11.

Therefore, for example, when the maintenance inspector operates the history output switch 37 at the time of the subsequent maintenance inspection, the history information categorized and recorded in the history event buffer 18 of the storage device 11 is displayed on a printer or a display. Can be output. By looking at the categorized and recorded history information, maintenance personnel can easily know when, where, and by what cause the abnormality, especially the non-fire alarm, occurred at any time. It is possible to easily and clearly understand the factors of non-fire alarms at the time of regular maintenance and inspection, and to take appropriate measures against these non-fire alarms.

Further, in this embodiment, when an abnormality occurs, the cause of the abnormality is surely input by the operator. That is, when the restoration operation is performed, conventionally, the display and the audio device are forcibly cleared and the restoration process is forcibly performed. However, in the present embodiment, the cause of the abnormality that should be input is still input. If not, the recovery process is not performed and the display,
The alarm output of the audio device is continued. Therefore, the recovery process cannot be performed without inputting any factor, which allows the operator to reliably input the factor causing the abnormality and to record it reliably.

However, when a large number of alarm operation tests are artificially performed, such as maintenance, if the factor cannot be restored unless the factor is input, the input procedure is troublesome. Especially, in the test restoration mode, maintenance is performed. Considering it is time,
At this time, as a cause of the abnormality, the keyboard 36
The content of the maintenance inspection is uniquely assigned and recorded regardless of the input from. Therefore, even if no input is made, the recovery process can be performed when the cause of the abnormality is recorded as described above. Of course, it is possible to input from the keyboard 36 that maintenance is to be performed.

In the above-mentioned embodiment, the cause of the abnormality is entered from the keyboard 36 by the code number.
It is also possible to enter this as information other than the code number (for example, in words). When the voice recognition device is built in the receiver 1, the operator can also input the cause of the abnormality (for example, the code number or word) by voice from a microphone or the like. It is also possible to enter the above code numbers and words without typifying them, but by categorizing them, it becomes possible to input data extremely easily, and it is extremely easy to manage and grasp records. Becomes

Further, in the above-mentioned embodiment, when the equipment, the line, or the like is in a failure state, the fact that the cause of the abnormality is the line failure is automatically recorded in the history event buffer 18. As a result, the burden on the operator can be reduced, but it is also possible for the operator to input the cause of this failure in the same manner as other causes of the abnormality.

Further, in the above-described embodiment, the case where the abnormality monitoring system is the conventional R type fire alarm system as shown in FIG. 1 has been described. For example, the R type fire alarm system as shown in FIG. Notification system (i.e., the analog sensors 107 connected to the transmission line 106 are sequentially and periodically called, and the analog data collected from each sensor 107 is evaluated. For example, the level of the analog data is predetermined for each sensor. When it is judged that a fire occurs because it is higher than the alarm level or the time increase rate of the analog data is larger than the value predetermined for each sensor, the display data assigned to each analog sensor 107 is displayed in the area. A system configured to turn on the fire lamp and sound the main audio device and the district audio device while displaying on the display window Is in each case a, also in the case of incorporating P-type fire alarm system within the receiver repeater 2 in FIG. 1, it is possible to apply the present invention just as. Furthermore, the present invention can be applied not only to a fire alarm system but also to a crime prevention system.

[0040]

As described above, according to the first aspect of the invention, the cause of the abnormality is inputted from the factor input means and recorded as history information. The cause of occurrence can be recorded and retained in the system as history information, and by outputting this history information to a printer or display at the time of maintenance and inspection, accurate information can be given to the operator and experience Can be effectively utilized for appropriate measures thereafter.

Further, according to the second aspect of the invention, since the cause of the abnormality can be typified and input, the input work can be easily performed, and the categorized and recorded history Based on the information, it is possible to easily and clearly identify the cause of abnormalities that occurred in the past (both true and false abnormalities can be included, especially the cause of false abnormalities) at the time of maintenance and inspection. We can grasp and take appropriate measures promptly.

According to the third aspect of the invention, if the cause of the abnormality that should be input is not input, the recovery process cannot be performed and the alarm is continuously output. The operator can be surely input.

According to the invention described in claim 4, the system can be switched to the test recovery mode for performing maintenance and inspection, and when the system is in the test recovery mode, an abnormality occurs. When detected, the recording means uniquely assigns the content of maintenance and inspection as the cause of the abnormality and records it, so that the input procedure at the time of maintenance and inspection becomes complicated. Can be avoided.
