Description

The present invention relates to a disaster prevention monitoring system that receives a signal from a fire detector or a gas leak detector connected to a signal line drawn out to a caution area with a receiver and outputs a fire alarm or a gas leak alarm.

In the disaster prevention monitoring system conventionally known as the R type, a fire sensor having a transmission function is connected to the transmission line drawn from the R type receiver, and the receiver is batch AD to the fire sensor at regular intervals. A conversion command is sent to detect sensor data such as smoke concentration and temperature, and then a poll command that specifies the address of the fire detector is sent to receive the sensor data in response, and the received sensor data is set as a predetermined threshold. By comparison, when the threshold is exceeded, it is judged as a fire, a fire alarm is output by sound or an indicator light, and the location of the fire is displayed from the sensor address where the fire was detected.

In the disaster prevention monitoring system known as P-type, on-off type detectors and transmitters are connected to the sensor line drawn from the P-type receiver to monitor fires on a line-by-line basis, and on-off type detection is performed. When a fire is detected by the device, the alarm current flowing through the line is detected by the P-type receiver, a fire alarm is output by sound or indicator light, and the area indicator light is turned on to indicate the area where the fire occurred. ing.

In the receiver of such a disaster prevention monitoring system, in order to display the system status, it monitors the failure of the receiver, the failure of the terminal equipment including the sensor, the wiring abnormality connecting the terminal equipment, etc. When a failure or abnormality is detected in the system, the failure representative light provided in the receiver is turned on and a failure alarm sound is output to notify the system.

When a failure is notified by the receiver in this way, the location of the failure and the details of the failure are displayed on the LCD panel or display such as LED provided in the receiver, and the person in charge of disaster prevention, etc. takes necessary measures after seeing this. Will be done.

Japanese Unexamined Patent Publication No. 08-255294 Japanese Unexamined Patent Publication No. 2009-087111 Japanese Unexamined Patent Publication No. 07-262474 Japanese Unexamined Patent Publication No. 2010-272023

However, in such a conventional disaster prevention monitoring system, although the location and details of individual failures that have occurred in the system are displayed, the monitoring function is lost and human life is affected unless the failed failures are dealt with immediately. There is a problem that users who are unfamiliar with the devices that make up the system cannot determine whether there is a problem or whether there is no problem in dealing with it at a later date, and it takes time to take appropriate measures.

In addition, users who cannot determine the extent of the failure will be anxious, so even if there is no problem in dealing with it at a later date, they will make an emergency call to the maintenance maker, and even if it is a minor failure, for example, at midnight. In some cases, it is a burden on the maintenance maker.

The present invention provides a disaster prevention monitoring system that enables the user to appropriately deal with a failure that has occurred by displaying the system status with a weighting of how much the system is affected when a failure is detected. With the goal.

The present invention relates to a disaster prevention monitoring system.
A control unit that monitors the status of system components, evaluates the degree of system failure, and outputs it.
A system status indicator that is provided separately from the display unit that displays the disaster prevention alarm and that displays the degree of failure output by the control unit.
It is characterized by being equipped with.

When the disaster prevention alarm is displayed by the display unit, the control unit stops the display of the degree of failure by the system status display.

The display unit and the system status indicator are arranged on the same surface of the receiver that outputs the disaster prevention alarm.

(Basic effect)
The present invention is a disaster prevention monitoring system that receives a detection signal from a detector connected to a signal line drawn to a caution area by a receiver and outputs an alarm, and is a system including a receiver, a detector, and a signal line. A control unit that monitors the status of components, 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, and the control unit issues a disaster prevention alarm by the display unit. When it was displayed, the display of the degree of failure by the system status indicator was stopped, and the display unit and the system status indicator were placed on the same surface of the receiver that outputs the disaster prevention alarm, so that a failure occurred. In some cases, by looking at the display on the system status indicator, it is easy for the user to know whether or not the failure requires immediate action, and by taking appropriate measures to repair the failure, the effect of the failure is minimized. It can be stopped. In addition, even if a minor failure occurs, the user can easily identify it, reducing the need for emergency calls such as midnight due to anxiety and reducing the work burden of maintenance manufacturers. Make it possible.

(Evaluation by assigning rank or score for failure)
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 the failure of the system component is detected, the rank or the score assigned to the detected failure. Since the degree of failure is displayed on the system status indicator according to the above, the degree of failure can be evaluated constantly by rank or score, and the system status 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 rank or score assignment indicating the degree of failure according to the failure type of the system component based on the setting operation, the rank or score indicating the degree of failure is required according to the content of the failure. It can be changed as appropriate according to the above.

(Effect of evaluation 1 by assigning rank or score to failure)
In addition, when the control unit detects a state including a failure of a system component, it has at least one stage of failure including a predetermined rank or score, and the system component has deteriorated over time and is replaced at the next inspection. It is classified into one of the required stages of aging with the next rank or high score of failure and the lowest rank or the lowest point without failure in the system components, and assigned to the classified stage. Since the degree of failure is displayed on the system status indicator according to the rank or score, it can be judged that immediate action is required if the failure reaches the specified rank or score, and the system is normal in terms of aging deterioration. It can be judged that there is no problem by judging that the state is in a state, and further, if there is no failure at the lowest rank or the lowest point, it can be judged that the state is completely normal.

(Effect of evaluation by assigning rank or score to failure)
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 and the disaster prevention monitoring by the receiver are possible, but a signal. There is a line failure The second failure with the next highest rank or score after the first failure, disaster prevention monitoring by the receiver is possible, and the signal line is normal, but failure information is input to the receiver from an external device. The third failure with the next highest rank or score after the second failure, and the fourth highest rank or score after the third failure that has deteriorated over time and needs to be replaced at the next inspection. It is classified into one of the stages of failure and the lowest rank or the lowest point where no failure has occurred in the system components, and the degree of failure is displayed on the system status indicator according to the rank or score assigned to the classified stage. Is displayed, so if it is the first failure with the highest rank or the highest score, it can be judged that immediate response is necessary, and if it is the second failure with the next highest rank or score, it can be judged to be dealt with at a later date, and then If it is a third failure with a low rank or score, it can be judged that it is sufficient to take measures with a margin, and if it is a fourth failure with a next rank or low score, it can be judged that no action is required until the next periodic inspection. Further, in the fourth failure, it can be determined that the system is in a normal state without any problem, and further, if there is no failure at the lowest rank or the lowest point, it can be determined that there is no failure and the state is completely normal.

(Effect of status display by highest rank or highest score for multiple failures)
Further, when the control unit detects a plurality of failures in the system components, the control unit displays the degree of failure on the system status indicator according to the highest rank or the highest score among the detected multiple failures. It is possible to display the system status due to the failure with the highest priority among the failures.

(Effect of status display by total rank or score for multiple failures)
Further, when the control unit detects a plurality of failures in the system components, the control unit displays the degree of failure on the system status indicator according to the total score of the detected failures. Therefore, for example, a plurality of failures with a low score occur. If it has occurred, the system status is displayed, which corresponds to a failure with a higher score than the failure that has occurred, and even if the failure has a low rank or score, the risk as a system is high because multiple failures have occurred. Therefore, it is possible to take appropriate measures by increasing the degree of failure.

(Effect of stopping the status display at the time of disaster prevention alarm)
In addition, the control unit stops the display of the failure degree by the system status indicator when the disaster prevention alarm is output from the receiver. Therefore, when the fire alarm is issued, the failure degree by the system status indicator is stopped. Is not necessary and may confuse the alarm display, so stop the system status indicator and turn it off.

(Effect of a display that increases the number of displays or the amount of display according to the degree of failure)
Further, since the system status indicator is provided with a display element whose display number or display amount increases as the failure degree increases, the failure degree is displayed by, for example, the number of LED displays or the expansion of the display area by a bar graph. By doing so, it is possible to intuitively judge the degree of failure by looking at the display.

(Effect of the display that changes from cool colors to warm colors as the degree of failure increases)
In addition, the system status indicator changes the display color from a cold-colored safe color to a warm-colored dangerous color according to the increase in the degree of failure. For example, the system status indicator is green as the degree of failure increases. Alternatively, since the display color is changed from blue to yellow and then to red, it is possible to intuitively determine the degree of failure based on the display color of the system status indicator.

(Effect of displaying the degree of failure by the meter display)
Further, since the system status indicator is a meter display in which the swing width or the angle of rotation of the pointer 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 display color of the single indicator light)
In addition, the system status indicator is equipped with a single indicator lamp, and the display color of the indicator lamp is changed according to the degree of failure, which simplifies the display of the system status and the degree of failure can be determined simply by looking at the display color. It is easy to judge.

(Effect of display of failure degree by blinking cycle)
In addition, since the system status indicator changes the blinking cycle of the indicator light according to the degree of failure, for example, by controlling to shorten the blinking cycle according to 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 done, 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 that changes the display form of failure according to the degree of failure)
Further, since the control unit changes the display form of the failure information by the liquid crystal display provided in the receiver according to the increase in the degree of failure, for example, the character color and the character size of the failure information displayed on the liquid crystal display. By changing <and fonts, etc. according to the increase in the degree of failure, it is possible to strongly appeal to the user how much the degree of failure is, and to make it easier to identify the failure that has occurred.

[Outline 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 of a building, a manager's room, or the like, and is a fire detector having a transmission function, a gas leak detector connected via a repeater, or the like. Sensors are connected via a transmission line to monitor abnormalities such as fires and gas leaks, and control equipment such as district acoustic devices are connected to the transmission line to enable control operation.

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

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

The operation unit 16 is provided with a fire / gas leak determination switch, an acoustic stop switch, a district acoustic pause switch, and the like exposed to the outside. Further, inside the child door 17 of the operation unit 16, a recovery switch, a district acoustic simultaneous ringing switch, a batch interlocking stop switch, etc. are provided, and the child door 17 is closed in the normal monitoring state, and the child is closed when necessary. The door 17 is opened downward to operate the switch.

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

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

Therefore, by looking at the display of the system status indicator 20, when a failure occurs, it is easy for the user to know whether or not the failure requires immediate action, and the failure can be repaired by appropriate measures. The effect of failure can be minimized. In addition, even if a minor failure occurs, the user can easily identify the minor failure from the display of the system status indicator 20, and is driven by anxiety to make an emergency call such as at midnight. It is possible to reduce the work load of the maintenance maker.

(Disaster prevention monitoring system)
FIG. 2 is a block diagram showing an outline of the R-type disaster prevention monitoring system. In FIG. 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 report transfer unit 28, and a system status display 20.

A transmission line 30 is drawn from the R-type receiver 10 toward the warning 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 detector 38 and a transmitter 40 are connected to the sensor line 36 drawn from the repeater 34. A gas leak detector 42 is connected to another repeater 34.

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

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

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

On the other hand, the uplink signal from the analog sensor 32 and the repeater 34 is transmitted in the current mode. In this current mode, a signal current is passed through the transmission line 30 at the timing of bit 1 of the transmission data, and an uplink 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. The R-type receiver 10 transmits a polling command for normal monitoring in which terminal addresses are sequentially specified during normal monitoring, and the analog detector 32 and the repeater 34 poll to match their own set addresses. When a command is received, a normal monitoring response is sent. Therefore, in the R-type receiver 10, a failure can be detected by using the analog sensor 32 or the repeater 34, which did not respond to the polling command, as a failure.

Further, the R-type receiver 10 repeatedly transmits the batch AD conversion command every transmission cycle of the polling command for all terminal addresses. When the analog detector 32 receives the batch AD conversion command from the R-type receiver 10, the analog detection data such as the detected smoke concentration and temperature is sampled and compared 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 the 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 1.

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 issues a fire or gas. When a leak is detected, an interrupt signal is transmitted to the R-type receiver 10.

When the R-type receiver 10 receives the interrupt signal from the analog detector 32 or the repeater 34, it issues a group search command and interrupts from the group including the analog detector 32 or the repeater 34 that has detected a fire. Receive the response to determine the group.

Subsequently, the individual analog detectors and repeaters included in the identified group are sequentially polled by specifying the address, and the analog that detects the fire is detected by receiving a fire response such as analog data and fire alarm data. The detector address of the detector 32 or the repeater 34 is recognized, and a fire alarm operation is performed.

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

Failure monitoring of the R-type receiver 10 includes, for example, a standby power supply abnormality, a standby power supply voltage abnormality, a receiver memory abnormality, a receiver communication abnormality, a receiver unit abnormality, a printer abnormality, a printer paper shortage, and the like. Further, in the failure monitoring of the R-type receiver 10, the useful life of the equipment constituting the system is managed, and when the useful life approaches, the deterioration over time is determined.

Failure monitoring of the transmission line 30 includes transmission line disconnection failure, transmission line termination failure, 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 failure monitoring of an external device, there is input of failure information from, for example, a fire extinguishing pump facility that inputs various displays to the R-type receiver 10.

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

As shown in FIG. 3, the system status indicator 20 of the present embodiment has, as a display element indicating an increase in the degree of failure, in the order from the one with the highest degree of failure to the one with the lowest degree of failure (in the order from right to left). The first failure indicator 46a, the second failure indicator 46b, the third failure indicator 46c, the fourth failure indicator 46d, and the failure-free indicator 46e using LEDs or the like are arranged, and the danger due to the failure is arranged on the upper side thereof. A numerical value of 1 to 5 is displayed as a risk number 45 indicating the strength of the degree, and a triangular safety display marker 48 indicating the degree of the system state on the safe side (OK) and the system state are displayed below the numerical value. Is provided with a triangular danger display marker 50 indicating how much the danger side (NG) is.

The display color of the first failure indicator 46a is red, the display color of the second failure indicator 46b is orange, the display color of the third failure indicator 46c is yellow, and the display color of the fourth failure indicator 46d is light green. Alternatively, the display color of the blue, no-fault indicator 46e is dark green or blue, and if the degree of danger is low, that is, if the degree of safety is high, the display color is a cold green or blue color, and if the degree of danger is high, yellow. , Orange, red warm color display color.

In the present embodiment, as shown in FIG. 4, the control unit 22 of the R-type receiver 10 sets the failure items detected by the disaster prevention monitoring system into ranks and points indicating, for example, five levels of failure degree according to the contents. It is divided.

The first failure is a failure with a maximum score of 10 points at the highest rank A, which may affect human life because disaster prevention monitoring by the receiver cannot be performed. The first failure includes an abnormality in the standby power supply of the R-type receiver 10, an abnormality in the standby power supply voltage, an abnormality in the memory in the receiver, an abnormality in communication in the receiver, an abnormality in the unit in the receiver, a transmission line disconnection failure in the transmission line 30, and an analog sensor 32. , Duplicate address of repeater 34, disconnection of terminal, internal abnormality, etc. are included.

The second failure is a failure in which the signal line is abnormal although disaster prevention monitoring by the receiver is possible, and the failure has a score of 3 points at rank B, which is the second highest after the first failure. This second failure includes a transmission line termination failure of the transmission line 30, a serial communication abnormality, and the like.

For the third failure, disaster prevention monitoring by the receiver is possible and the signal line is normal, but when failure information is input to the receiver from an external device, printer paper runs out that does not require immediate response, etc. This is a failure with a rank C and 2 points, which is the second highest after the second failure.

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 equipment, but the system components deteriorate over time and should be replaced at the next inspection. This is a required failure, and is a failure with a score of 1 at rank D, which is the second highest after the third failure. This fourth failure is functioning normally as a disaster prevention monitoring system, and the degree of danger as a system is extremely low.

No failure means that no failure has occurred in the system components, the minimum point is 0 at the lowest rank E, and there is no problem in the system state.

Further, the control unit 22 of the R-type receiver 10 changes the allocation of ranks or points indicating the degree of failure according to the failure type of the system component shown in FIG. 4 by a predetermined setting operation, if necessary. be able to.

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

FIG. 5A is a display of the system status when a first failure having a maximum score of 10 points is detected at the highest rank A in the degree of failure of FIG. 4, and is a display of the first failure indicator 46a and the second failure indicator. Three of 46b and the third failure indicator 46c are lit or blinking, and the system state is in the state of the highest risk, and immediate response to the detected failure is required.

FIG. 5B is a display of the system status when a second failure with a score of 3 is detected at rank B in the degree of failure of FIG. 4, and is a display of the second failure indicator 46b and the third failure indicator 46c. Two are lit or blinking, and immediate action is not required, but prompt action is required.

FIG. 5C is a display of the system status when a third failure with a score of 2 is detected at rank C in the degree of failure in 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 out of paper, and it is not appropriate to leave it unattended, so it should be dealt with as soon as possible.

FIG. 5D is a display of the system status when a fourth failure with a score of 1 is detected at rank D in the degree of failure of FIG. 4, and only the fourth failure indicator 46d is lit or blinking. Since there is time to deal with it, for example, it is sufficient to check the equipment that has reached the end of its useful life and consider how to replace it.

FIG. 5E is a display of the system status when no failure with a score of 0 is detected at rank E in the degree of failure of FIG. 4, and the fourth failure indicator 46d and the failure-free indicator light 46e are displayed. It is lit or flashing and the system is in perfect condition.

(Status display by total rank or score for multiple failures)
When the control unit 22 of the R-type receiver 10 detects a plurality of failures in the system components, the control unit 22 may display the degree of failure on the system status display 20 according to the total score of the detected failures. ..

For example, when the control unit 22 detects the third failure and the fourth failure in FIG. 4, the control unit 22 obtains three points, which are the points of two points and one point, respectively, and corresponds to the second failure one rank higher. The degree of failure is displayed on the system status display 20. As a result, even if a failure has a low score, the risk of the system is high because multiple failures occur, so it is possible to take appropriate measures by displaying the system status with a high degree of failure.

(Stop displaying the status at the time of disaster prevention alarm)
When the control unit 22 of the R-type receiver 10 outputs a fire alarm or a gas leak alarm, the control unit 22 controls to stop the display of the degree of failure by the system status indicator 20 and turn off the display. When the disaster prevention alarm is output in this way, by turning off the display of the system status indicator 20, it is possible to prevent the display of the disaster prevention alarm such as fire or gas leak from being confused by the display of the system status indicator 20. do.

For example, when a fire alarm is output, if the system status indicator 20 has a system status display due to a failure of another sensor as shown in FIG. 5A, it is determined that the system status indicator is a false alarm due to the failure. There is a possibility that the system status indicator 20 will be turned off to prevent such confusion.

(Display of the degree of failure by the 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 the present embodiment is provided with a ring-shaped scale 62 on the instrument panel, and the ring-shaped scale 62 has the first to fourth failures of FIG. 4 and no failure. It is divided into regions 62e to 62a having corresponding risks 1 to 5, and a meter pointer 64 that rotates according to an increase in the degree of failure is provided.

As shown in FIGS. 6A to 6E, the display operation by the meter-type system status indicator 60 is based on the evaluation of the degree of failure due to the detected first to fourth failures and no failure, and the meter pointer 64. The ring-shaped scale 62 corresponding to the evaluation result is rotated so as to indicate the area 64e to 64a of the corresponding risk level 5 to 1, and the risk level of the system is intuitively grasped from the position of the meter pointer 64 by failure detection. Can recognize the system status.

Further, the meter-type system status display 60 may be an analog meter or a digital meter. Further, 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.

[Modified example of the present invention]
(P-type receiver)
The above embodiment takes an R-type disaster prevention monitoring system as an example. Similarly, for the P-type disaster prevention monitoring system, a system status indicator is provided in the P-type receiver, and the degree of danger and the degree of failure are determined according to the degree of failure. Alternatively, the safety level may be displayed.

(Evaluation by assigning rank or points)
In the above embodiment, the system state is evaluated by classifying into five stages of first failure to fourth failure and no failure and assigning ranks or points, but as another embodiment, the R-type receiver 10 When the control unit 22 detects a state including a failure of a system component, at least one stage of failure including a predetermined rank or score and aged deterioration of the system component occur, and the control unit 22 needs to be replaced at the next inspection. It is classified into one of the following stages of failure, the aging deterioration with the next rank or high score, and the lowest rank or the lowest point where no failure has occurred in the system components, and it is assigned to the classified stage. The degree of failure may be displayed on the system status indicator according to the rank or score.

Further, in the above embodiment, the system state is evaluated by dividing it into five stages, but the present invention is not limited to this, and for example, there are three stages of major failure, minor failure, and no failure, and other appropriate multi-stages. It may be evaluated separately.

(System status indicator)
As another embodiment of the system status indicator, the system status indicator may be a single indicator lamp, and the display color of the indicator lamp may be changed according to the degree of failure. The change in the display color of the indicator lamp in this case changes the display color from a cold-colored safe color to a warm-colored dangerous color according to the increase in the degree of failure.

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

Further, the display form of the system status indicator is not limited to the above embodiment, and an appropriate display configuration can be taken.

(Display color control according to the degree of failure of the receiver display)
Further, the control unit 22 of the R-type receiver 10 changes the display form of the liquid crystal panel 15 provided in the R-type receiver 10 according to the increase in the degree of failure. For this change in the display form, for example, the character color of the failure information displayed on the liquid crystal panel 15 is changed from a cold-colored safe color to a warm-colored dangerous color according to an increase in the degree of failure, or the character size of the failure information is changed. The size is changed to increase as the degree of failure increases. Further, the character font of the failure information may be changed in size 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 form of the failure information of the liquid crystal panel 15 according to the increase in the degree of failure in this way, it is possible to strongly appeal to the user how much the degree of failure is, and it is easier to identify the failure that has occurred. To do something.
