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 warning area by a receiver and outputs a fire alarm or a gas leak alarm.

  Conventionally, in a disaster prevention monitoring system known as an R type, a fire detector having a transmission function, for example, is connected to a transmission line drawn from an R type receiver, and a batch AD is sent from the receiver to the fire detector at a constant cycle. Sending a conversion command to detect sensor data such as smoke concentration and temperature, and then receiving a response by sending a polling command specifying the address of the fire detector. In comparison, when a threshold is exceeded, it is determined that there is a fire, a fire alarm is output by sound or indicator light, and the location of the fire is displayed from the sensor address that detected the fire.

  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 the fire on a line-by-line basis. When a fire is detected by the device, the alarm current flowing in the line is detected by the P-type receiver, a fire alarm is output by sound and indicator lights, and the district where the fire occurred is indicated by lighting the district indicator lights. ing.

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

  In this way, when a failure is reported by the receiver, the failure location and the failure content are displayed by a display such as a liquid crystal panel or LED provided in the receiver, and the disaster prevention personnel etc. take necessary measures by looking at this. Will do.

Japanese Patent Laid-Open No. 08-255294 JP 2009-087111 A

  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 does not occur immediately, the monitoring function will be lost and human life will be affected. There is a problem that a user who is unfamiliar with the devices constituting the system cannot determine whether there is a problem or whether there will be a problem with the response at a later date.

  In addition, users who cannot determine how much the failure will be affected are worried, so even if there is no problem with the response at a later date, an emergency call is made to the maintenance manufacturer, and even if it is a minor failure, for example at midnight This is a burden on the maintenance manufacturer.

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

(Displays the status by the highest rank or the highest number of points for multiple failures)
When detecting a plurality of failures for the system component, the control unit displays the failure degree on the system status display according to the highest rank or the highest number of points among the detected failures.

(Status display by rank or total score for multiple failures)
When a plurality of failures are detected for the system component, the control unit displays the failure degree on the system status display according to the total rank or the total score of the detected plurality of failures.

(Status display stop at disaster warning)
When the controller outputs an alarm from the receiver, the controller stops the display of the failure degree by the system status indicator.

(Indicators that increase the number of displays or display amount according to the degree of failure)
The system status indicator includes a display element whose display number or display amount increases as the failure degree increases.

(Indicator that changes from cold color to warm color as the degree of failure increases)
The system status indicator changes the display color from a cold-colored safety color to a warm-colored dangerous color according to an increase in the degree of failure.

(Indication of failure degree by meter display)

For example, the character color, character size and font of the failure information displayed on the liquid crystal display Etc. are changed according to the increase in the failure degree.

(Basic effect)
The present invention relates to a disaster prevention monitoring system that receives a detection signal from a detector connected to a signal line led out to a warning area by a receiver and outputs an alarm, and includes a receiver, a detector, and a signal line. Since a control unit that monitors the status of the component and evaluates and outputs the failure degree of the system and a system status indicator that displays the failure degree output by the control unit are provided, when a failure occurs, By looking at the display on the system status indicator, it is easy for the user to determine whether or not the failure needs immediate attention, and by repairing the failure with appropriate measures, the effects of the failure can be minimized. it can. In addition, even if a minor failure occurs, the user can easily identify this, reducing the need for emergency calls such as late night due to anxiety, and reducing the burden on maintenance manufacturers. Make it possible.

(Evaluation by assigning rank or points for failure)
In addition, 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 score assigned to the detected failure Accordingly, the failure degree is displayed on the system status indicator according to the condition, so that the failure degree is regularly evaluated by rank or score, and the system state can be displayed according to the degree of the failure.

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

(Effect of evaluation 1 by assigning rank or points to failure)
In addition, when the control unit detects a state including a failure of the system component, at least one stage of failure including a predetermined rank or number of points and a system component that has deteriorated over time, the control unit should be replaced at the next inspection. It is classified into one of the following stages: the next rank of failure or high aging of the score, and the lowest rank or no failure where the system component has not failed. Since the failure status is displayed on the system status indicator according to the rank or score, it can be determined that if a failure has a predetermined rank or score, immediate response is necessary. There is no problem in judging that it is in a state, and further, no failure of the lowest rank or lowest point can be judged as a completely normal state.

(Effect of evaluation by assigning rank or points to failure)
In addition, when the controller detects a state including a failure of the system component, the first rank or the highest number of first failures that cannot be monitored by the receiver and the disaster monitoring by the receiver are possible. The second fault with the next highest rank or point after the first fault that has a fault on the line and the disaster prevention monitoring by the receiver is possible and the signal line is normal, but the fault information is input from the external device to the receiver A third fault with the next highest rank or score after the second fault, and a fourth fault with the second highest rank or score after the third fault that has deteriorated over time and requires replacement at the next inspection. Classify the failure into either the lowest rank where no failure has occurred in the system components or no failure at the lowest point, and check the system status indicator according to the rank or score assigned to the classified step. Display Therefore, if it is the first failure with the highest rank or the highest score, it can be determined that immediate response is necessary. If it is the second failure with the next highest rank or score, the response can be determined at a later date. If it is a low third failure, it can be determined that a response with a margin is acceptable, and if it is a fourth failure with the next rank or low score, it can be determined that no response is required until the next periodic inspection. It can be determined that there is no problem in determining that the system is in a normal state in the case of a failure, and that there is no failure of the lowest rank or the lowest score can be determined as a completely normal state in which there is no failure.

(Effect of status display by the highest rank or the highest number of points for multiple failures)
In addition, when the controller detects a plurality of failures for the system component, the controller displays the degree of failure on the system status indicator according to the highest rank or the highest number of the detected failures. It is possible to display the system state due to the failure having the highest priority among the failures.

(Effect of status indication by rank or total score for multiple failures)
In addition, when the control unit detects a plurality of failures for the system component, the control unit displays the failure degree on the system status display according to the total number of the detected failures. If a failure has occurred, the system status corresponding to a failure with a higher score than that of the failure that has occurred is displayed, and even if the failure has a lower rank or score, the system is highly dangerous due to multiple occurrences. Therefore, it is possible to increase the degree of failure and take appropriate measures.

(Effects of stopping the status display at the time of disaster prevention warning)
In addition, when the disaster prevention alarm is output from the receiver, the control unit stops the display of the failure level by the system status indicator, so when the 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 stop the system status indicator and turn off the display.

(Effect of display device that increases the number of displays or display amount according to the degree of failure)
In addition, 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, expanding the display area by the number of LEDs or a bar graph. By doing so, it is possible to intuitively determine the extent of the failure by looking at the display.

(Effect of indicator that changes from cold color to warm color as the degree of failure increases)
In addition, the system status indicator changes the display color from a cold-colored safety color to a warm-colored dangerous color as the failure degree increases. For example, the system status indicator displays green as the failure degree increases. Alternatively, since the display color is changed from blue to yellow through red, it is possible to intuitively determine how much the failure is based on the display color of the system status indicator.

(Effect of indication of failure level by meter display)
Further, since the system status indicator is a meter indicator in which the swing width or the rotation angle of the pointer increases as the failure degree increases, the failure degree can be easily determined by the position of the pointer.

(Effect of indication of failure degree by display color of single indicator)
In addition, the system status indicator has a single indicator light, and the display color of the indicator light is changed according to the failure degree, so the display of the system state becomes simple and the failure degree can be reduced by just looking at the display color. Easy to judge.

(Effect of failure degree display by blinking cycle)
In addition, since the system status indicator changes the blinking cycle of the indicator lamp according to the failure degree, for example, the disaster prevention monitoring by the receiver can be performed by controlling the blinking cycle to be shortened according to the increase of the failure degree. If it is 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 an emergency state that requires countermeasures.

(Effect of control that changes the display form of failure according to the degree of failure)
In addition, since the control unit changes the display mode of the failure information by the liquid crystal display provided in the receiver according to the increase in the failure degree, for example, the character color and the character size of the failure information displayed on the liquid crystal display By changing the font or the like in accordance with the increase in the failure degree, it is possible to strongly appeal to the user what the failure degree 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 view showing an R-type disaster prevention receiving board. As shown in FIG. 1, the R-type receiver 10 is installed in a disaster prevention center of a building, a manager's room, etc., such as a fire detector having a transmission function or a gas leak detector connected via a repeater. Sensors are connected via a transmission line to monitor abnormalities such as fires and gas leaks, and control devices such as district acoustic devices are connected to the transmission line to enable control operation.

  The R-type receiver 10 has a door-shaped receiver panel 12 disposed on the front surface of a 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 disposed on the upper side of the operation unit 16, and a switch is disposed on the lower side of the child door 17 that can be freely opened and closed.

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

  The operation unit 16 is provided with a fire / gas leak determination switch, an acoustic stop switch, a district acoustic temporary stop switch, and the like exposed to the outside. In addition, a recovery switch, a district sound simultaneous ringing switch, a batch 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 door 17 is opened downward and the switch is operated.

  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 to this, in this embodiment, a system status indicator 20 is provided on the receiver panel 12 of the R-type receiver 10. The system status indicator 20 displays the failure degree of the system components including the receiver itself, detectors such as fire detectors and gas leak detectors, and transmission paths, 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, when a failure occurs, it can be easily determined whether or not the user needs to deal with immediately, and by repairing the failure by appropriate measures, The effects of failure can be minimized. In addition, even when a minor failure occurs, the user can easily identify the minor failure from the display on the system status display 20, and make an emergency call such as midnight driven by anxiety. This makes it possible to reduce the operational burden on maintenance manufacturers.

(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 transfer unit 28, and a system status indicator 20.

  A transmission line 30 is drawn out from the R-type receiver 10 toward a facility security area, 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 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 unique addresses including the R-type receiver 10 are assigned in advance. For example, when the maximum number of addresses is 256 addresses, the number of analog sensors 32 and repeaters 34 that can be connected to one transmission line 30 excludes receiver addresses. 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 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 the voltage mode. The voltage mode signal is transmitted as a voltage pulse that changes the voltage of the transmission line 30 between 18 volts and 30 volts, for example.

  In contrast, upstream signals from the analog sensor 32 and the repeater 34 are transmitted in a 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 the upstream signal is transmitted to the receiver as a so-called current pulse train.

  Reception control by the control unit 22 of the R-type receiver 10 is as follows. During normal monitoring, the R-type receiver 10 transmits a normal monitoring polling command in which terminal addresses are sequentially specified, and the analog sensor 32 and the repeater 34 are polled to match their own set addresses. When a command is received, a normal monitoring response is made. For this reason, in the R-type receiver 10, a failure can be detected with the analog sensor 32 or the repeater 34 that has not responded to the polling command as a failure.

  The R-type receiver 10 repeatedly transmits a batch AD conversion command for each polling command transmission period for all terminal addresses. When the analog sensor 32 receives the batch AD conversion command from the R-type receiver 10, the analog sensor 32 samples analog detection data such as smoke density and temperature detected and compares them 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 status 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 fire alarm or gas When a leak is detected, an interrupt signal is transmitted to the R-type receiver 10.

  When 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 from the group including the analog sensor 32 or the repeater 34 that detects the fire. Receive the response to determine the group.

  Next, each analog sensor or repeater included in the identified group is polled in sequence by address, and the analog that detected the fire is received by receiving a fire response such as analog data or fire alarm data. The sensor address of the sensor 32 or the repeater 34 is recognized, and a fire alarm operation is performed.

(Fault monitoring of system components)
In addition, the control unit 22 of the R-type receiver 10 includes a system configuration including the receiver itself, the transmission line 30, the analog sensor 32, the repeater 34, and further external devices connected via the transfer unit 28. Monitor for element failure.

  Examples of failure monitoring of the R-type receiver 10 include standby power supply abnormality, standby power supply voltage abnormality, receiver memory abnormality, receiver communication abnormality, receiver unit abnormality, printer abnormality, and printer paper out. Furthermore, for failure monitoring of the R-type receiver 10, the service life of the devices constituting the system is managed, and when the service life approaches, the aging deterioration is determined.

  The failure monitoring of the transmission line 30 includes transmission line disconnection failure, transmission line termination failure, serial communication abnormality, and the like. The 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 the external device, there is an input of failure information from, for example, a fire pump facility that performs various display inputs to the R-type receiver 10.

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

  As shown in FIG. 3, the system status indicator 20 of the present embodiment is a display element indicating an increase in the failure degree, in order from the higher failure degree to the lower one (in 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. As a risk number 45 indicating the degree of intensity, a numerical value of 1 to 5 is displayed, and a triangular safety display marker 48 indicating the degree of the system state on the safe side (OK) and the system state below Is provided with a triangular danger display marker 50 that indicates how much is on the danger side (NG).

  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. 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, it is yellow. , Orange and red warm display colors.

  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 to, for example, ranks and scores indicating the five-step failure degrees according to the contents. It is divided.

  The first failure is a failure with a maximum score of 10 at the highest rank A, which cannot be monitored by the receiver for disaster prevention and may affect human life. This first failure includes a standby power supply abnormality of the R-type receiver 10, a standby power supply voltage abnormality, a receiver internal memory abnormality, a receiver internal communication abnormality, a receiver internal unit abnormality, a transmission line disconnection failure of the transmission line 30, and an analog sensor 32. Address duplication, terminal disconnection, internal abnormality, and the like.

  The second failure can be monitored by the receiver for disaster prevention, but is a failure with an abnormality in the signal line, and becomes a failure of 3 points at the rank B higher than the first failure. The second failure includes a transmission line termination failure of the transmission line 30, a serial communication abnormality, and the like.

  The third failure can be monitored by the receiver for disaster prevention, and the signal line is normal, but when the failure information is input from the external device to the receiver or the printer paper is out of necessity, etc. This is a failure with the next highest rank C and 2 points after the second failure.

  The fourth failure can be monitored by the receiver for disaster prevention, the signal line is normal, and there is no input of failure information from external devices. However, the system component has deteriorated over time and should be replaced at the next inspection. It is a necessary failure, and it becomes a failure with a score of one point at the rank D next to the third failure. This fourth failure is functioning normally as a disaster prevention monitoring system, and the risk as a system is extremely low.

  “No failure” means that no failure has occurred in the system components, the failure has a minimum score 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 rank or score assignment indicating the failure degree according to the failure type of the system component shown in FIG. 4 as necessary by a predetermined setting operation. be able to.

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

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

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

  FIG. 5C is a system status display when a third failure with a score of 2 points is detected at rank C in the failure degree of FIG. 4, and only the third failure indicator lamp 46 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 as it is, so it can be dealt with as quickly as possible.

  FIG. 5D is a system status display when a fourth failure with a score of 1 point is detected at rank D in the failure degree of FIG. 4, and only the fourth failure indicator lamp 46d is lit or blinking. Since there is a time margin for the response, for example, it is sufficient to examine a device whose service life is close and examine the response such as replacement.

  FIG. 5E shows a system state display when no failure with a score of 0 is detected at rank E in the failure degree of FIG. 4, and the fourth failure indicator lamp 46d and the no-failure indicator lamp 46e are two. Lights up or flashes and the system is in a completely normal state.

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

  For example, when the control unit 22 detects the third failure and the fourth failure in FIG. 4, three points obtained by adding two points and one point, which are the respective points, are obtained and correspond to the second failure on one rank. The degree of failure is displayed on the system status indicator 20. As a result, even if there is a failure with a low score, the risk as the system is high due to the occurrence of a plurality of failures. Therefore, appropriate handling is possible by displaying the system state with a high failure degree.

(Status display stop at disaster warning)
When the fire alarm or the gas leak alarm is output, the control unit 22 of the R-type receiver 10 performs control to stop the display of the failure degree by the system status indicator 20 and turn off the display. In this way, when the disaster prevention alarm is output, the display of the system status indicator 20 is turned off to prevent the display of the disaster alert such as a fire or gas leak from being confused by the display of the system status indicator 20 To do.

  For example, when a fire alarm is output, if the system status indicator 20 has a system status indication due to a failure of another sensor, for example, as shown in FIG. The display of the system status indicator 20 is turned off to prevent such confusion.

(Indication of failure degree 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. 6 (A), the system status indicator 60 of the present embodiment is provided with a ring scale 62 on the meter panel, and the ring scale 62 is free from the first failure to the fourth failure and failure shown in FIG. A meter pointer 64 that is divided into areas 62e to 62a of corresponding risk levels 1 to 5 and 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 first to fourth failures detected and the failure degree evaluation based on the absence of failure. Rotate the ring scale 62 corresponding to the evaluation result so as to point to the corresponding areas 64e to 64a of the risk level 5 to 1, and intuitively grasp the system risk level from the position of the meter pointer 64 to detect the failure. Can recognize the system status.

  The meter-type system status indicator 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 risk 1 to 5.

[Modification of the present invention]
(P-type receiver)
In the above embodiment, an R-type disaster prevention monitoring system is taken as an example. Similarly, for a P-type disaster prevention monitoring system, similarly, a system status indicator is provided in a P-type receiver, Alternatively, the safety level may be displayed.

(Evaluation by assignment of rank or points)
In the above embodiment, the system state is evaluated by assigning a rank or a score by classifying into five stages of the first failure to the fourth failure and no failure, but as another embodiment, the R type receiver 10 When the control unit 22 detects a state including a failure of the system component, the control unit 22 needs to be replaced at the next inspection due to at least one stage failure including a predetermined rank or score and aged deterioration of the system component. Is classified into one of the stages of the next rank of failure or high aging degradation and the lowest rank or no failure of the system component that has failed, and assigned to the classified stage You may make it display a failure degree on a system status indicator according to a rank or a score.

  In the above-described embodiment, the system state is evaluated in five stages. However, the present invention is not limited to this. For example, the system state is classified into three stages, that is, a major failure, a minor failure, and no failure, and other appropriate multiple steps. It may be divided and evaluated.

(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 failure degree. In this case, the change in the display color of the indicator lamp changes the display color from the cold-colored safe color to the warm-colored dangerous color in accordance with the increase in the failure degree.

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

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

(Display color control according to the failure level 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 failure degree. For example, the change in the display form may be performed by changing the character color of the failure information displayed on the liquid crystal panel 15 from a cold-colored safe color to a warm-colored dangerous color or increasing the character size of the failure information. The size is changed to increase as the failure degree increases. In addition, the character font of the failure information may be changed to increase in size according to the increase in the failure degree. Furthermore, both the character display color and the character size of the failure information may be changed according to the increase in the failure degree.

  In this way, by changing the display form of the failure information on the liquid crystal panel 15 according to the increase in the failure degree, it is possible to strongly appeal to the user what the failure degree is and to easily identify the failure that has occurred. Do something.
