  However, in such a conventional disaster prevention monitoring system, the location and details of each failure that occurred in the system are displayed, but if the failure is not dealt with immediately, the monitoring function is lost and human life is affected. There is a problem that a user unfamiliar with the equipment constituting the system cannot judge whether there is a problem or whether there is no problem in the measures at a later date, and it takes time to take appropriate measures.

  Also, a user who cannot judge how much the failure has an effect is anxious, so even if there is no problem with the response at a later date, make an emergency call to the maintenance maker, and even if it is a minor failure, This is a burden on the maintenance maker.

  An object of the present invention is to provide a disaster prevention monitoring system in which when a failure is detected, a user can appropriately deal with the generated failure by displaying a system status with a weight of how much the system is affected. With the goal.

A system status indicator for displaying the degree of failure output by the control unit;
Is provided.

  The control unit, when detecting a state related to the failure of the system component, evaluates the state related to the failure according to the presence / absence of the failure and a method of responding to the failure, and displays a failure degree according to the evaluation result on the system status display. I do.

  The control unit, when detecting a state related to the failure of the system component, evaluates the state related to the failure according to the presence / absence of the failure and the availability of disaster prevention monitoring, and displays a failure degree according to the evaluation result on the system state display. .

  When the control unit detects a state related to the failure of the system component, the control unit classifies the state into at least one of failure, aging, and no failure, and classifies the result into a system state indicator. The corresponding failure level is displayed.

  The control unit evaluates the degree of failure by classifying the state relating to the failure into a plurality of stages.

(Basic effects)
The present invention relates to a disaster prevention monitoring system that receives a detection signal from a detector connected to a signal line drawn out to a guard area and outputs an alarm, the system including a receiver, a detector, and a signal line. Because a control unit that monitors the state of the components and evaluates and outputs the degree of failure of the system and a system status indicator that displays the degree of failure output by the control unit are provided, when a failure occurs, By looking at the display of the system status indicator, it is easy for the user to determine whether the failure requires immediate attention, and by taking appropriate measures to repair the failure, it is possible to minimize the effects of the failure. it can. In addition, even in the case of a minor failure, the user can easily recognize the failure, and it is less likely to make an emergency call at midnight due to anxiety, thereby reducing the work load of the maintenance maker. Make it possible.

(Evaluation by assigning ranks or points to failures)
Further, the control unit assigns a predetermined rank or a predetermined score indicating the degree of failure according to the failure type of the system component, and when a failure of the system component is detected, the rank or the score assigned to the detected failure. The degree of failure is displayed on the system status display in accordance with (1), so that the degree of failure can be evaluated in a constant manner by rank or score, and the system state can be displayed according to the degree of failure.

(Effect of changing rank or score for failure)
In addition, since the control unit can change the assignment of the rank or point indicating the failure degree according to the failure type of the system component based on the setting operation, the control unit needs the rank or point indicating the failure degree according to the failure content. Can be appropriately changed according to the conditions.

(Effect of evaluation 1 by assigning ranks or points to failures)
In addition, when detecting a state including a failure of the system component, the control unit replaces at least one stage failure including a predetermined rank or score, and aging of the system component occurs during the next inspection. It is classified into any of the following stages, requiring high aging with the next rank or score of failure, and no failure with the lowest rank or minimum point where no failure has occurred in the system component, and is assigned to the classified stage. The system status indicator displays the degree of failure according to the rank or score.If a failure has a predetermined rank or score, it can be determined that immediate action is necessary. If there is no problem with the lowest rank or the lowest point, it can be determined that the state is completely normal.

(Effect of evaluation by assigning ranks or points to failures)
Further, when the control unit detects a state including a failure of a system component, the first failure of the highest rank or the highest score that cannot be monitored by the receiver for disaster prevention and the disaster prevention monitoring by the receiver are possible, The second fault of the next highest rank or score next to the first fault with a fault in the line and the disaster prevention monitoring by the receiver are possible, and the signal line is also normal, but fault information is input to the receiver from an external device. And a fourth fault with the next highest rank or score next to the second fault, and a third fault with the next highest rank or score after the second fault and a third fault that needs to be replaced at the next inspection due to aging of the system components. Failures are classified into any of the following stages: the lowest rank where no failure has occurred in the system component or the lowest failure point. Display Therefore, if the first failure has the highest rank or the highest point, it can be determined that immediate response is required. If the second failure has the next highest rank or score, the response can be determined at a later date. If the third failure is low, it can be determined that a response with a margin is sufficient, and if the fourth failure has a low rank or score, it can be determined that no response is required until the next periodic inspection. If there is a failure, it is determined that the system is in a normal state, and there is no problem. Further, if there is no failure of the lowest rank or the lowest point, it can be determined that there is no failure and a completely normal state.

(Effect of status display by highest rank or highest score for multiple failures)
Further, the control unit, when detecting a plurality of failures for the system components, to display the degree of failure on the system status indicator according to the highest rank or the highest score among the plurality of detected failures, a plurality of The system status due to the highest priority fault among the faults can be displayed.

(Effect of status display by total rank or score for multiple failures)
Further, when the control unit detects a plurality of faults for the system components, the control unit displays the degree of failure on the system status indicator according to the total score of the plurality of detected faults. If a fault has occurred, the system status corresponding to a fault with a higher score than the fault that has occurred is displayed, and even if a fault has a lower rank or score, the risk of the system is higher due to the occurrence of multiple faults. As a result, the degree of failure can be increased and appropriate measures can be taken.

(Effect of stopping the status display at the time of disaster prevention warning)
In addition, the control unit stops displaying the degree of failure by the system status indicator when a disaster prevention alarm is output from the receiver, so that when a fire alarm is issued, the failure level by the system status indicator is displayed. Is not necessary, and the alarm display may be confused, so the system status indicator is stopped and the display is turned off.

(Effects of a display unit that increases the number of displays or display amount according to the degree of failure)
In addition, the system status indicator is provided with a display element whose display number or display amount increases in accordance with an increase in the degree of failure, so that the degree of failure is displayed, for example, by increasing the number of displayed LEDs or the display area by a bar graph. By doing so, it is possible to intuitively determine the degree of failure by looking at the display.

(Effect of the display that changes from a cold color system to a warm color system in accordance with an increase in the degree of failure)
In addition, the system status indicator changes the display color from a cold color safety color to a warm color danger color in accordance with the increase in the degree of failure.For example, the system status indicator changes the green color in accordance with the increase in the degree of failure. Alternatively, since the display color is changed from blue to yellow and then to red, it is possible to intuitively determine how much failure has occurred based on the display color of the system status indicator.

(Effect of displaying the degree of failure on the meter display)
Further, since the system status indicator is a meter indicator whose swing width or rotation angle increases as the degree of failure increases, the degree of failure can be easily determined from the position of the pointer.

(Effect of displaying the degree of failure by the color of the single indicator light)
In addition, the system status indicator has a single indicator light and changes the display color of the indicator light according to the degree of failure, so the display of the system status is simple, and the failure level can be determined simply by looking at the display color. Easy to judge.

(Effect of displaying the degree of failure by blinking cycle)
In addition, the system status indicator changes the blinking cycle of the indicator light in accordance with the degree of failure.For example, by controlling the blinking cycle to be shorter in accordance with the increase in the degree of failure, disaster prevention monitoring by the receiver can be performed. In the case of a serious failure that cannot be performed, the indicator light blinks continuously in a short cycle, and it can be easily determined that the system is in a system state that requires urgent action.

(Effect of control to change the display mode of failure according to the degree of failure)
Further, the control unit changes the display mode of the failure information on the liquid crystal display provided in the receiver in accordance with the increase in the degree of failure, so that, for example, the character color and character size of the failure information displayed on the liquid crystal display By changing the font, font, and the like according to the increase in the degree of failure, it is possible to strongly appeal to the user what the degree of failure is, and it is possible to easily identify the failure that has occurred.

[Overview of disaster prevention monitoring system]
(R type receiver)
FIG. 1 is an explanatory diagram showing an R-type disaster prevention receiver. As shown in FIG. 1, the R-type receiver 10 is installed in a disaster prevention center or a manager's office of a building, and is provided with a fire detector having a transmission function or a gas leak detector connected via a repeater. Sensors are connected by a transmission line to monitor abnormalities such as fire and gas leaks, and control equipment such as a local acoustic device is connected to the transmission line to enable control operation.

  The R-type receiver 10 has a receiver panel 12 having a door structure on the front of a box-shaped housing. On the receiver panel 12, a display unit 14, an operation unit 16, and a printer 18 are arranged. An exposed switch is arranged on the upper side of the operation unit 16, and a switch is arranged on the lower side inside a child door 17 that can be opened and closed.

  The display unit 14 is provided with a fire representative light, a gas leak representative light, various indicator lights indicating a failure of an external device, and the like.

  The operation unit 16 is provided with a fire / gas leak determination switch, a sound stop switch, a local sound stop switch, and the like, which are exposed to the outside. A recovery switch, a regional sound simultaneous sounding switch, a collective interlock stop switch, and the like are provided inside the child door 17 of the operation unit 16, and the child door 17 is closed in a normal monitoring state. The switch is operated by opening the door 17 downward.

  When an event such as a fire alarm or a gas leak alarm is performed by the R-type receiver 10, the printer 18 prints out the event occurrence time and the event content.

  In addition, in this embodiment, a system status indicator 20 is provided on the receiver panel 12 of the R-type receiver 10. The system status display 20 displays the degree of failure of system components including the receiver itself, detectors such as a fire detector and a gas leak detector, and transmission lines, which are monitored and evaluated by the R-type receiver 10. .

  For this reason, by looking at the display of the system status indicator 20, it is easy to determine whether or not the user needs to take immediate action when a failure occurs, and the failure can be repaired by taking appropriate action. The effects of failure can be minimized. In addition, even when a minor failure occurs, the user can easily recognize that the failure is minor from the display of the system status display 20, and the user can be worried to make an emergency call at midnight or the like. And reduce the burden on the maintenance maker.

(Disaster prevention monitoring system)
FIG. 2 is a block diagram showing an outline of the R-type disaster prevention monitoring system. 2, the R-type receiver 10 is provided with a control unit 22, a transmission unit 24, a display unit 14, an operation unit 16, an alarm unit 26, a transfer unit 28, and a system status display 20.

  A transmission line 30 is drawn out from the R-type receiver 10 toward a security area of the facility, and an analog sensor 32 is connected to the transmission line 30 as a detector.

  A repeater 34 is connected to the transmission line 30, and an on / off sensor 38 and a transmitter 40 are connected to a sensor line 36 drawn from the repeater 34. A gas leak detector 42 is connected to another relay 34.

  The analog sensor 32 and the repeater 34 have a transmission function of bidirectionally transmitting information to and from the R-type receiver 10, and unique addresses including the R-type receiver 10 are assigned in advance. The number of the analog sensors 32 and the repeaters 34 that can be connected to one transmission line 30 is, for example, 255 or less analog sensors 32 and the repeaters 34 when the maximum number of addresses is 256, excluding the receiver address. Can be connected.

  The control unit 22 of the R-type receiver 10 is configured by a computer circuit having a CPU, a memory, and various input / output ports, and performs a predetermined receiver control by executing a program.

  Downstream signals from the R-type receiver 10 to the analog sensor 32 and the repeater 34 are transmitted in a voltage mode. The voltage mode signal is transmitted as a voltage pulse that changes the voltage of the transmission line 30 between, for example, 18 volts and 30 volts.

  On the other hand, the upstream signals from the analog sensor 32 and the repeater 34 are transmitted in the current mode. In this current mode, a signal current flows through the transmission line 30 at the timing of bit 1 of the transmission data, and an upstream signal is transmitted to the receiver as a so-called current pulse train.

  The reception control by the control unit 22 of the R-type receiver 10 is as follows. At the time of normal monitoring, the R-type receiver 10 transmits a polling command for normal monitoring in which terminal addresses are sequentially specified, and the analog sensor 32 and the repeater 34 perform polling matching with their own set addresses. When a command is received, a normal monitoring response is performed. Therefore, in the R-type receiver 10, a failure can be detected by using the analog sensor 32 or the repeater 34 that has not responded to the polling command as a failure.

  Further, the R-type receiver 10 repeatedly transmits a batch AD conversion command in each transmission cycle of polling commands for all terminal addresses. Upon receiving the batch AD conversion command from the R-type receiver 10, the analog sensor 32 samples analog detection data, such as the detected smoke density and temperature, and compares it with a predetermined fire level.

  When the analog detection data sampled by the analog sensor 32 exceeds the fire level, an interrupt signal is transmitted to the R-type receiver 10 at a response timing to the polling command. This interrupt signal sends a signal that is not normally used such that the response bit string is all ones.

  The repeater 34 also samples the reception state of the on / off sensor 38 or the gas leak detector 42 connected to the sensor line 36 based on the batch AD conversion command from the R-type receiver 10 and outputs a fire alarm or gas. If a leak is detected, an interrupt signal is transmitted to the R-type receiver 10.

  Upon receiving the interrupt signal from the analog sensor 32 or the repeater 34, the R-type receiver 10 issues a group search command and interrupts the group including the analog sensor 32 or the repeater 34 that has detected the fire. Receive the response and determine the group.

  Then, the analog detectors and repeaters included in the determined group are sequentially polled by specifying their addresses, and receive a fire response such as analog data or fire alarm data. The address of the sensor of the sensor 32 or the repeater 34 is recognized, and the fire alarm operation is performed.

(Failure monitoring of system components)
Further, the control unit 22 of the R-type receiver 10 includes a system configuration including the receiver itself, a transmission line 30, an analog sensor 32, a repeater 34, and an external device connected via a transfer unit 28. Monitors for element failure.

  The failure monitoring of the R-type receiver 10 includes, for example, an abnormality in a standby power supply, an abnormality in a standby power supply voltage, an abnormality in a memory in the receiver, an abnormality in communication in the receiver, an abnormality in a unit in the receiver, an abnormality in the printer, and an out-of-printer paper. Further, for the failure monitoring of the R-type receiver 10, the service life of the equipment constituting the system is managed, and when the service life approaches, the aging is judged.

  The failure monitoring of the transmission line 30 includes a transmission line disconnection failure, a transmission line termination failure, a serial communication abnormality, and the like. Failure monitoring of the analog sensor 32 and the repeater 34 includes address duplication, terminal disconnection, internal abnormality, and the like. Further, as the failure monitoring of the external device, there is an input of failure information from, for example, a fire extinguishing pump facility which performs various display inputs to the R-type receiver 10.

(System status display and failure degree evaluation)
FIG. 3 is an explanatory diagram showing the system status indicator provided in the R-type receiver shown in FIG. 1, and FIG. 4 is an explanatory diagram showing a list of the relationship between a failure item and a rank indicating the degree of failure and a score.

  As illustrated in FIG. 3, the system status indicator 20 according to the present embodiment includes, as display elements indicating an increase in the degree of failure, in an order from a higher degree of failure to a lower degree of failure (an order from right to left): A first failure indicator 46a, a second failure indicator 46b, a third failure indicator 46c, a fourth failure indicator 46d, and a failure-free indicator 46e using LEDs or the like are arranged. A numerical value of 1 to 5 is displayed as a risk degree number 45 indicating the degree of the degree, and a triangular safety display marker 48 indicating the degree of the system state being on the safe side (OK) below the numerical value, and a system state Is provided with a triangular danger display marker 50 indicating that the degree is on the danger side (NG).

  The display color of the first failure display 46a is red, the display color of the second failure display 46b is orange, the display color of the third failure display 46c is yellow, and the display color of the fourth failure display 46d is light green. Or blue, the display color of the failure-free indicator 46e is dark green or blue, and when the degree of danger is low, that is, when the degree of safety is high, the display color is green or blue, and when the degree of danger is high, yellow. , Orange and red warm colors.

  In the present embodiment, as shown in FIG. 4, the control unit 22 of the R-type receiver 10 converts a failure item detected by the disaster prevention monitoring system into a rank and a score indicating, for example, a five-level failure degree according to the content. Divided.

  The first failure is a failure having a maximum score of 10 at the highest rank A, which cannot be monitored for disaster prevention by the receiver and may possibly affect human life. The first failure includes an abnormal standby power supply of the R-type receiver 10, an abnormal standby power supply voltage, an abnormal memory in the receiver, an abnormal communication in the receiver, an abnormal unit in the receiver, a transmission line disconnection failure of the transmission line 30, an analog sensor 32 And the repeater 34, such as address duplication, terminal disconnection, and internal abnormality.

  The second fault is a fault that can be monitored by the receiver for disaster prevention, but has a fault in the signal line, and is a fault with a score of 3 on rank B next to the first fault. The second failure includes a transmission line termination failure of the transmission line 30, a serial communication abnormality, and the like.

  The third fault is that the receiver can perform disaster prevention monitoring and the signal line is normal, but the fault information is input to the receiver from an external device, or the printer is out of paper without immediate action. , And the fault having the rank C and the score of 2 points next to the second fault.

  For the fourth failure, disaster prevention monitoring by the receiver is possible, the signal line is normal, and there is no input of failure information from external devices. However, the system components have deteriorated over time and must be replaced at the next inspection. This is a required fault, and is a fault with a score of 1 in the rank D next higher than the third fault. This fourth failure is functioning normally as a disaster prevention monitoring system, and the risk of the system is extremely low.

  When there is no failure, no failure has occurred in any of the system components, the failure has a minimum point of 0 at the lowest rank E, and there is no risk as a system state.

  Further, the control unit 22 of the R-type receiver 10 changes the assignment of the rank or the score indicating the degree of failure according to the failure type of the system component illustrated in FIG. be able to.

(Evaluation and display of failure degree)
FIG. 5 is an explanatory diagram showing a display of ranks A, B, C, D, and E on the system status indicator.

  FIG. 5A is a display of a system state when the first failure having the highest score of 10 points in the highest rank A in the failure degree of FIG. 4 is detected, and includes a first failure indicator 46a and a second failure indicator. Since three of the 46b and the third failure indicator 46c are lit or blinking, the system state is in the highest risk state, and it is necessary to immediately respond to the detected failure.

  FIG. 5B is a display of a system state when a second fault with a score of 3 points is detected at rank B in the fault degree of FIG. 4, and the second fault indicator 46b and the third fault indicator 46c are displayed. Two of them are lit or flashing, and no immediate response is required, but a prompt response is required.

  FIG. 5 (C) is a display of the system state when the third failure with two points is detected at rank C in the failure degree of FIG. 4, and only the third failure indicator 46c is lit or blinking. It is a minor failure such as a failure of an external device or a printer paper shortage, and it is not appropriate to leave it unattended.

  FIG. 5D is a display of the system state when the fourth failure with one point is detected at rank D in the failure degree of FIG. 4, and only the fourth failure indicator 46d is lit or blinking. Since there is ample time for the response, for example, it is only necessary to examine a device whose service life is approaching and to consider a response such as replacement.

  FIG. 5E is a display of the system state when no fault with a score of 0 is detected at rank E in the fault degree of FIG. 4, and two of the fourth fault indicator 46d and the fault-free indicator light 46e are displayed. Lights or flashes, indicating that the system is in a completely normal state.

(The status is displayed by rank or total score for multiple failures.)
When detecting a plurality of faults for the system components, the control unit 22 of the R-type receiver 10 may display the degree of fault on the system status display 20 according to the total score of the plurality of detected faults. .

  For example, when the control unit 22 detects the third fault and the fourth fault in FIG. 4, three points are obtained by adding the respective points, two points and one point, and correspond to the second fault on one rank. The degree of failure is displayed on the system status display 20. As a result, even if a fault with a low score occurs, the risk of the system is high due to the occurrence of a plurality of faults, so that appropriate measures can be taken by displaying the system state with a high fault level.

(Stop status display at the time of disaster prevention alarm)
When the fire alarm or the gas leak alarm is output, the control unit 22 of the R-type receiver 10 stops the display of the degree of failure by the system status indicator 20 and controls the display to disappear. When the disaster prevention alarm is output in this way, the display of the system status display 20 is turned off so that the display of the disaster prevention alarm such as a fire or a gas leak is prevented from being confused by the display of the system status display 20. I do.

  For example, when a fire alarm is output, if the system status indicator 20 displays a system status caused by a failure of another sensor as shown in FIG. In such a case, the display of the system status indicator 20 is turned off to prevent such confusion.

(Indication of degree of failure by meter display)
FIG. 6 is an explanatory diagram showing the display of ranks A to E indicating the degree of failure by the meter type system status indicator.

  As shown in FIG. 6A, the system status indicator 60 of this embodiment has a ring scale 62 provided on the meter panel, and the ring scale 62 has no first to fourth failures and no failure in FIG. It is divided into areas 62e to 62a corresponding to the danger levels 1 to 5, and a meter pointer 64 that rotates in accordance with an increase in the degree of failure is provided.

  As shown in FIGS. 6A to 6E, the display operation of the meter type system status indicator 60 is performed based on the evaluation of the first to fourth failures detected and the degree of failure due to no failure, as shown in FIGS. Is rotated so as to point to the corresponding areas 62e to 62a of the risk degree 5-1 of the ring scale 62 corresponding to the evaluation result, and the risk degree of the system is intuitively grasped from the position of the meter pointer 64 to detect the failure. Recognize system status.

  Further, the meter type system status indicator 60 may be an analog meter or a digital meter. In addition to the display by the meter pointer 64, the background color of the meter panel may be changed to green or blue, light green or blue, yellow, orange, or red according to the degree of danger 1 to 5.

[Modification of the present invention]
(P-type receiver)
In the above embodiment, the R-type disaster prevention monitoring system is taken as an example. However, for the P-type disaster prevention monitoring system, a system status indicator is similarly provided on the P-type receiver, and the risk level and the risk level are set according to the degree of failure. Alternatively, the safety level may be displayed.

(Evaluation by assigning ranks or points)
In the above-described embodiment, the system state is evaluated by classifying the system into five stages of the first to fourth failures and no failure, and assigning a rank or a score to evaluate the system state. When detecting a state including a failure of the system component, the control unit 22 requires at least one-step failure including a predetermined rank or score and aging of the system component to be replaced at the next inspection. Categorized into any of the following stages of failure, high aging with the next rank or score, and the lowest rank or minimum point where no failure has occurred in the system component, and assigned to the classified stage. The degree of failure may be displayed on the system status indicator according to the rank or the score.

  In the above embodiment, the system state is evaluated in five stages. However, the present invention is not limited to this. For example, there are three stages of a major failure, a minor failure, and no failure, and other appropriate multiple stages. May be divided and evaluated.

(System status display)
As another embodiment of the system status indicator, the system status indicator may be a single indicator light, and the display color of the indicator light may be changed according to the degree of failure. In this case, the change in the display color of the indicator lamp changes the display color from a cold color safety color to a warm color danger color in accordance with an increase in the degree of failure.

  Further, as another embodiment of the system status indicator, the blinking cycle of the indicator light may be changed according to the degree of failure. In this case, the change of the blinking cycle of the indicator light is controlled so as to shorten the blinking cycle in accordance with the increase in the degree of failure.

  Further, the display mode of the system status display is not limited to the above-described embodiment, and may have an appropriate display configuration.

(Display color control according to the degree of failure of the receiver display unit)
Further, the control unit 22 of the R-type receiver 10 changes the display mode of the liquid crystal panel 15 provided in the R-type receiver 10 according to an increase in the degree of failure. This change in the display mode may be achieved by, for example, changing the character color of the failure information displayed on the liquid crystal panel 15 from a cold color safety color to a warm color danger color in accordance with an increase in the degree of failure, or changing the character size of the failure information. The size is changed to increase according to the increase in the degree of failure. Further, the size of the character font of the failure information may be changed to increase according to the increase in the degree of failure. Further, both the character display color and the character size of the failure information may be changed according to the increase in the degree of failure.

  By changing the display mode of the failure information on the liquid crystal panel 15 in accordance with the increase in the failure degree in this way, the user is strongly informed of the degree of the failure degree, and the occurrence of the failure can be easily identified. Do something.
