It is an effective technology when applied to equipment).

Techniques have been proposed for monitoring anomalies in a plurality of broadcast transmitters and broadcast repeaters that constitute microwave transmitters and transmitters for digital terrestrial broadcasting.

For example, Japanese Patent Application Laid-Open No. 2011-097503 discloses that, in an audio STL device that transmits a main line signal, such as an audio signal, in which it is difficult to determine whether a silent state is good or bad, there is a digital A transmission device is disclosed.

The present inventors are also developing a monitoring device for monitoring a plurality of broadcast transmission devices and broadcast relay devices and a remote control device (hereinafter referred to as a remote control device) having the monitoring device. This remote control device has a logging function with a log function for storing alarm occurrence items, alarm occurrence time, alarm recovery items, and alarm recovery time, and the display screen of the remote control device has a log display section for displaying the log. is doing.

However, when an alarm actually occurs, a large number of alarms occur, and it is difficult for the end user who actually uses the remote control device to analyze what is happening even by looking at the log. It was found that failure analysis could not be easily performed.

For example, let us consider a situation in which, in a microwave transmission device and a transmitter for terrestrial digital broadcasting, devices B and G fail and signals do not flow to the subsequent stages. It is assumed that a plurality of apparatuses (equipment) are connected between the apparatus B and the apparatus G. FIG. Of course, device B is detected by its own abnormality, but a plurality of devices after device B that receive the output signal of device B can detect that the signal from device B has not arrived and issue an abnormality. be. If anomalies continue in this way, all the devices after device B will appear to have anomalies. When an inexperienced user checks this situation on the display screen of the operation means (also called an operation terminal) of the monitoring device or the remote control device, it is impossible to determine where the original abnormality originated. In particular, the apparatus G may be buried in the notification of the abnormal state that the signal does not come, and it may not be possible to immediately determine that the abnormal state is originally notified autonomously.

An object of the present disclosure is to provide a monitoring device having a display format that enables a clear determination of where an abnormal situation exists.

Other problems and novel features will become apparent from the description of the specification and the accompanying drawings.

Hereinafter, embodiments and examples will be described with reference to the drawings. However, in the following description, the same components may be denoted by the same reference numerals, and repeated descriptions may be omitted. In addition, in order to clarify the description, the drawings may be represented schematically as compared with the actual embodiments, but they are only examples and do not limit the interpretation of the present invention.

First, in order to facilitate understanding, a configuration example and problems of a microwave transmission device and a transmitter for terrestrial digital broadcasting, and a remote control device provided therein will be described with reference to FIGS. 1 and 2. FIG.

FIG. 1 is a block diagram showing a configuration example of an overall broadcasting system according to an embodiment. FIG. 2 is a block diagram showing another configuration example of the overall broadcasting system according to the embodiment.

FIG. 1 shows a configuration example of an overall digital terrestrial broadcasting system (hereinafter also referred to as a broadcasting system) 100 including a microwave transmission device, a transmitter, and a remote control device for digital terrestrial broadcasting. Broadcasting stations generally have outside bases such as transmitting stations, relay stations, base stations, etc., which serve as bases 2 for radio transmission for broadcasting, in addition to the head office 1 . These are generally located on top of mountains or on the roofs of buildings, and are installed in places with good visibility from the surrounding area. This base 2 is equipped with radio equipment for broadcasting. In order for the head office 1 to constantly grasp the state of these facilities, a remote control device (in FIG. 1, a remote control terminal station 1, an operation means (operation terminal) 1, a remote control terminal station 2, an operation means (also referred to as an operation terminal) 2) is installed. Used. The broadcasting system 100 is composed of two locations, a head office 1 and a base located outside the company 2. A plurality of broadcast transmission devices for performing radio transmission for broadcasting are present at the head office 1 and base 2, respectively. Also, remote control terminal stations 1 and 2 are often installed at the head office 1 or base 2 where there is a broadcast transmission device to be remotely controlled (hereinafter referred to as a remote controller) to collectively manage a group of devices at that location. For example, if the remote control interface of the device is IP (Internet Protocol) and an IP line is connected to another point, there is a method of centralized control at a remote control terminal station located at another point.

The remote control terminal station 1, the operating means 1, the remote control terminal station 2, and the operating means 2 are configured to include a monitoring device ME. Further, the remote controllers 1 and 2 have a logging function that stores or saves the detection of an abnormality in the storage device MM as data of an alarm occurrence item, an alarm occurrence time, an alarm return item, and an alarm return time. have. The display screens of the operating means 1 and 2 have log display sections for displaying logs.

The remote control terminal stations 1 and 2 use the remote control interfaces (for example, contact points, serial communication, IP communication, analog voltage transfer, etc.) possessed by each broadcast transmitter at the location (head office 1 or base 2). Communicate, control and monitor. Here, "control" means giving instructions and settings from the remote control terminals 1 and 2 to each broadcast transmission device, and "monitoring" means that the remote control terminals 1 and 2 obtain the status and settings from each broadcast transmission device. It is to be. These remote controller information for control and monitoring are shared with the operating means 1 and 2 at the location (the head office 1 or the base 2). In general, the display screens of the operating means 1 and 2 are provided with user interfaces. The control in the operation means 1 and 2 is issued, for example, by the user's mouse click or keyboard depression on the display screen of the operation means 1 and 2 . As for the monitoring of the operation means 1 and 2, for example, as a GUI (graphic user interface) on the display screen of the operation means 1 and 2, the operation of the device is monitored in accordance with the mode such as buttons and characters, colors, and lines on the display screen. Indicates the state (abnormal state, normal state).

The operation means 1 and 2 do not necessarily have to acquire information from the remote control terminals 1 and 2 at the same location. There is another way to obtain it. By using this, for example, if only the operation means 1 is installed at the head office 1, and the device group, the remote control terminal station 2, and the operation means 2 are installed at the base 2 side, the overall system as shown in FIG. It is also possible to configure

Here, remote control terminal station 1 and remote control terminal station 2 (Fig. 1) at each location (headquarters 1 and base 2), or operation means 1 and remote control terminal station 2 (Fig. 2) are connected between head office 1 and base 2. It is configured so that information can be exchanged via the control and monitoring line prepared in . The control and monitoring lines include, for example, 4W (4-wire) leased lines, 2W (2-wire) leased lines, 2W public lines, STL (Studio To Transmitter Link)/TSL (Transmitter To Studio Link), and other wireless transmission equipment. Audio superimposition, serial superimposition, IP line, etc. can be used.

1 and 2, the device group of a plurality of broadcast transmission devices constituting the broadcast system 100 shown in FIG. 1 has a signal flow ( hereinafter referred to as a system) often exists. Referring to FIG. 1, information is transmitted in the direction of the arrows such that a signal transmitted from device A is sent to device B, and from device B to devices C1 and C2. Here, the device B receives a signal from one system, transmits a signal to two systems, and divides and distributes the signal (passes the same signal to a plurality of systems). Apparatus E receives signals from two systems and transmits signals to one system, and shares (combines) signals and selects (outputs any one of input signals to a subsequent stage).

In this example, a head office 1 is provided with devices A, B, C1, C2, D1, D2, and E as a plurality of broadcast transmission devices, and a base 2 is provided with devices F, G1, and G2 as a plurality of broadcast transmission devices. , H, I, J1, J2, K1, K2, L are provided. Transmission and reception are performed between the device E and the device F using microwaves. The output of device L is connected to a transmitting antenna for digital terrestrial broadcasting.

In the broadcasting system 100 of FIGS. 1 and 2, for example, devices A, B, C1, C2, D1, D2, and E are on the STL line (Studio to Transmitter Link) side for transmitting broadcast content from a studio. , devices F, G1, G2, H, and I can be regarded as receivers (STL receivers STLRX) on the STL line side, and devices J1, J2, K1 , K2, L can be viewed as transmitters (TX). In this example, the signal system including the devices C1 and D1 is the first STL transmission system STLTX1, and the signal system including the devices C2 and D2 is the second STL transmission system STLTX2. A signal system including the device G1 is assumed to be a first STL receiving system STLRX1, and a signal system including the device G2 is assumed to be a second STL receiving system STLRX21. A signal system including the devices J1 and K1 is referred to as a first transmission system TX1, and a signal system including the devices J2 and K2 is referred to as a second transmission system TX2.

It is important for the operating means 1 and 2 to express the state of the broadcasting system 100 in an easy-to-understand manner for the user. A major point of this representation is the system display. For example, in the system display, on the display screens of the operation means 1 and 2, as shown in FIGS. 1 and 2, the flow of material signals is simulated from left to right, and the devices are arranged from left to right in the order of transmission. Alternatively, each device is connected with an arrow to indicate to which device the material signal flows.

Also, what is important for the display screens of the operation means 1 and 2 is how to express the abnormality of the device in an easy-to-understand manner. As a method of displaying an abnormal state, when an abnormality occurs, use the color, text, line type, blinking, etc. of the panel or button on the display screen to make it different from normal. It is preferable to sound a warning sound from above the operation means 1 and 2 . Thereby, it is preferable that the user can detect an abnormality in the broadcasting system 100 at an early stage.

Next, the problem of the abnormal state display method described above will be described.

In the broadcasting system 100 of FIGS. 1 and 2, for example, let us consider a situation in which device B and device G1 fail and signals do not flow to the subsequent stage. Of course, device B is detected by its own abnormality, but the subsequent equipment may detect that the signal has not arrived and issue an abnormality. If anomalies continue in this way, all the devices after device B will appear to have anomalies. When an inexperienced user confirms this situation on the display screens of the operation means 1 and 2, it is impossible to determine where the original abnormality originated. In particular, the device G1 may be buried in an abnormal condition report (abnormality report) in which no signal is received, and may not be able to immediately determine that the device G originally autonomously issues an abnormality report.

Next, the unit numbers, alarm items and subordinate alarm codes will be explained with reference to FIG. FIG. 3 is a diagram for explaining unit numbers, alarm items, and subordinate alarm codes. It should be noted that FIG. 3 illustrates a representative example for easy understanding. Actually, there are multiple alarm items for one device.

A unit number is assigned to each of a plurality of broadcast transmitters (A, B, C1, C2, D1, D2, E, F, G1, G2, H, I, J1, J2, K1, K2, L). there is That is, a unit number is assigned to each unit to be monitored, and a unit with a smaller unit number is set as a higher-level unit. In this example, device A assigned unit number 1 is the highest unit, and device L assigned unit number 12 is the lowest unit. Conversely, a unit with a larger unit number may be set as a higher-level unit.

If the signal is split or split, the two corresponding devices are assigned the same unit number. That is, the same unit number 3 is assigned to the devices C1 and C2, and the same unit number 4 is assigned to the devices D1 and D2. Similarly, each of devices G1 and G2, each of devices J1 and J2, and each of devices K1 and K2 are also assigned the same unit number.

The alarm item indicates the alarm item of each device. Here, when an abnormal state is detected by the monitoring device ME for the alarm item B of the device B, each device (C1, C2, D1, D2, E, F, G1, G2, H, I, J1, J2, K1 , K2, L) are known to inevitably occur. In other words, it is known that the alarm items B1-B10 in the latter stage are always generated when the specific alarm B in the previous stage (apparatus B) is generated. Therefore, code 1 is assigned as each subordinate alarm code for each device (B, C1, C2, D1, D2, E, F, G1, G2, H, I, J1, J2, K1, K2, L). there is

On the other hand, the alarm item G for the devices G1 and G2 is originally an alarm item specific to the devices G1 and G2 in which the devices G1 and G2 autonomously report abnormal states. That is, the abnormal state of the alarm item G of the devices G1 and G2 is detected by the monitoring device ME separately from the abnormal state of the alarm item B5. Therefore, code 2 is assigned as each subordinate alarm code for devices G1 and G2.

Now, let us consider a situation where the devices B and G1 fail and no signal flows to the subsequent stages. Apparatus B is of course detected by the monitoring apparatus ME in its own abnormal state, but each subsequent apparatus detects that the signal has not arrived, and similarly the abnormal state is detected by the monitoring apparatus ME. be. That is, each device (B, C1, C2, D1, D2, E, F, G1, G2, H, I, J1, J2, K1, K2, L) to which code 1 of the subordinate alarm code is assigned is in an abnormal state. will be judged. Here, referring to the unit number, each device (B, C1, C2, D1, D2, E, F, G1, G2, H, I, J1, J2, K1, K2, L), the device having the highest unit number (corresponding to device B in this example) can be identified as the device causing the abnormality. Therefore, the abnormal state of the device G1 caused by the abnormal state of the device B can be distinguished or discriminated from the alarm item G specific to the devices G1 and G2. Therefore, it is possible to determine where the original abnormality has occurred.

Next, display examples on the display screens of the operation means 1 and 2 will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is a diagram showing a display example 1 on the display screen when an abnormal state occurs in the devices B and G1. FIG. 5 is a diagram showing a display example 2 on the display screen when an abnormal state occurs in the devices B and G1. In FIGS. 4 and 5, the abnormal state of each device is indicated by a thick frame.

Referring to FIG. 4, when device B issues an alarm due to alarm item B, as described with reference to FIG. , I, J1, K1, L) also report an abnormal state. Here, even though the device G1 has issued an individual abnormal state due to the alarm item G, the individual abnormal state reporting of the device G1 is overlooked due to the abnormal state of the device B. It will be.

On the other hand, in FIG. 5, an element specifying button 211 is provided on the display screens of the operating means 1 and 2. When the element specifying button 211 is clicked or selected with a mouse, display example 1 of FIG. 4 to display example 2 of FIG. is configured to change the display to When the element specifying button 211 is clicked or selected again with the mouse, display example 2 in FIG. 5 is changed to display example 1 in FIG.
In display example 2 of FIG. 5, the abnormal states of the devices B and G are displayed, and the abnormal states of the other devices (C1, D1, E, F, H, I, J1, K1, L) are not displayed. state.

In the case of color display, an abnormal state is displayed in red, for example, and a normal state that is not an abnormal state is displayed in green, for example. Here, in FIG. 5, when the display example 1 in FIG. 4 is changed to the display example 2 in FIG. 5 by clicking or selecting the element specifying button 211, other devices (C1, D1, E, F, H, The colors of I, J1, K1, L) can be different from red and blue, eg yellow.

The element identification button 211 can be regarded as a button for identifying and canceling the identification of the device that is the cause or element of the abnormal state. When the element identification button 211 is clicked or selected to identify the device that is the cause or element of the abnormal state, the unit number and subordinate alarm code in FIG. ). The remote control terminal stations 1 and 2 determine that the device with the highest unit number (device B in this example) is the cause or factor of the abnormal state among the devices with the subordinate alarm code "1". As a result, the display of the abnormal state of the device (device B in this example) that is considered to be the cause or element of the abnormal state is continued (displayed in red). Similarly, the display of the abnormal state of the device whose individual subordinate alarm code is "2" (device G1 in this example) continues (displayed in red). Devices (C1, D1, E, F, H, I, J1, K1, L) abnormal state changes to non-display display state (changes from red to yellow). As a result, the user can relatively easily identify the device (the device B and the device G1 in this example) that is considered to be the cause or factor of the abnormal state on the display screens of the operation means 1 and 2 .

When display example 2 shown in FIG. , F, H, I, J1, K1, L) to a non-display display state, the device (C1, D1, E, F, H, I, J1, K1, L ) should be omitted. This makes it easier to understand the original abnormality history. That is, in the case of the display example 1 shown in FIG. 4, the log display section shows a total of 11 abnormal states of each device (B, C1, D1, E, F, G1, H, I, J1, K1, L). Shown as a log. On the other hand, in the case of display example 2 shown in FIG. 5, a total of two abnormal states of each device (B, G1) are displayed as logs in the log display section.

Even if no abnormality is detected, even if the signal of the device B is determined to be abnormal on the display screens of the operation means 1 and 2, by displaying the same display as in FIG. Anomalies can be visually displayed and extracted. In this way, if no abnormality is detected and the signal is abnormal on the display screen, it is possible to visually notify that there is a silent failure.

In other words, a predetermined unit number among a plurality of unit numbers for each device is associated with the connection state of a plurality of units (units to which unit numbers are attached are assumed to be one unit) constituting each device of a plurality of broadcast transmission devices. A common code (subordinate alarm code) is assigned to each unit number. Then, when the log in which the abnormal situation is detected is displayed on the display screens of the operation means 1 and 2, the code common to the unit number of the log (the subordinate alarm code is "1") is assigned to another unit number. The state is highlighted at the same time as the unit number concerned (see FIG. 4). Then, when displaying logs in which a plurality of abnormal situations are detected in a predetermined range of time zones, a code common to each unit number (a subordinate alarm code is "1") of the plurality of abnormal logs is compared, In the case of the same common code (subordinate alarm code is "1"), only the device with the higher unit number is highlighted (see FIG. 5).

In addition, when displaying a log in which an abnormal condition of a signal is detected, by displaying the signal state of the higher-level device (here, device B) of the unit number of the log (see FIG. 5), the silent abnormal state can be displayed. can be extracted and distinguished relatively easily.

Next, a configuration example of the display screens of the operation means 1 and 2 will be described with reference to FIG. FIG. 6 is a diagram for explaining a configuration example of the display screen of the operating means.

As shown in FIG. 6, the display screens 20 of the operation means 1 and 2 include a display section 21 in which function control buttons are arranged, a display section 22 in which display portion selection buttons are arranged, and a display section 22 in which log display control buttons are arranged. It has a unit 23 , a display unit 24 for displaying log data (log history), and a display unit 25 . The display content displayed on the display unit 25 varies depending on the selection (pressing) state of the function control button arranged on the display unit 21 and the selection (pressing) state of the display part selection button arranged on the display unit 22. The display can be configured to switch.

The function control buttons arranged on the display unit 21 include, for example, function control buttons such as "monitoring control", "log data", and "element identification". The display portion selection buttons arranged on the display unit 22 include, for example, “whole”, “STL TX”, “STL RX”, “TX1”, “TX2”, and “monitoring data list” display portion selection buttons. The log display control buttons arranged on the display unit 23 include, for example, a device selection button and buttons for designating non-display conditions ("Caution", "Alarm", "Control", etc.).

FIG. 6 shows an enlarged “specify element” button 211 arranged on the display unit 21 . In this example, the “specify element” button 211 is provided on the display unit 21 , but the “specify element” button may be provided anywhere on the screen of the display screen 20 .

By selecting the "monitoring control" button and the "whole" button, system display can be performed on the display unit 25. FIG. The display state of the system display displayed on the display unit 25 will be conceptually described with reference to FIG. FIG. 7 is a diagram conceptually explaining a display example 1 of the system display displayed on the display unit. FIG. 8 is a diagram conceptually explaining display example 2 of the system display displayed on the display unit. 7 and 8, as an example, the first STL transmission system STLTX1, the second STL transmission system STLTX2, the first STL reception system STLRX1, the second STL reception system STLRX21, the first transmission system TX1, and the second transmission system of FIGS. TX2 is used to express the system display. A first system is composed of a first STL transmission system STLTX1, a first STL reception system STLRX1 and a first transmission system TX1, and a second system is composed of a second STL transmission system STLTX2, a second STL reception system STLRX2 and a second transmission system TX2. is configured. An "abnormality" display area for displaying an abnormal state is added to the lower side of each system. 7 and 8 also show the state of the "identify element" button 211. FIG. When the "identify element" button 211 is clicked or selected, the unit number and subordinate alarm code shown in FIG. 3 are referred to as described with reference to FIG.

In FIG. 7, an abnormal state has occurred in the first STL transmission system STLTX1. As a result, an abnormal state has occurred. FIG. 7 is the same as display example 1 in FIG. The "abnormality" display area below each system indicates an abnormal state (thick frame: highlighted state). At this time, the "specify element" button 211 is neither clicked nor selected. Here, it is assumed that the first STL receiving system STLRX1 and the first transmitting system TX1 have no abnormality in individual alarm items.

In FIG. 8, the "specify element" button 211 is clicked or selected (thick frame). FIG. 8 is the same as display example 2 in FIG. Based on the click or selection of the "identify element" button 211, the "abnormality" display area below the first STL transmission system STLTX1 maintains the state indicating abnormality (thick frame). On the other hand, the "abnormal" display area below the first STL receiving system STLRX1 and the first transmitting system TX1 is changed to a state other than abnormal (thin frame: non-highlighted state). As a result, as described with reference to FIG. 5, only the first STL transmission system STLTX1 in the abnormal state can be extracted as the device that is the cause or element of the abnormal state.

Since a silent failure can be displayed in the same manner as in FIG. 8, it is possible to visually display or notify the fact that a silent failure has occurred on the display unit 25 .

FIG. 9 is a diagram for explaining a display example of the log history on the display unit 24 in the case of FIGS. 7 and 8. In FIG. In FIG. 9, the log history RG1 on the upper side indicates the log history in the display state of FIG. 7, and the log history RG2 on the lower side indicates the log history in the display state of FIG. In the log history RG1, three histories of the first STL transmission system STLTX1, the first STL reception system STLRX1, and the first transmission system TX1 in an abnormal state are displayed. On the other hand, in the history RG2, since only the history of the first STL transmission system STLTX1 in the abnormal state is displayed, the original abnormality history can be easily understood. Based on the click or selection of the “specify element” button 211, the display on the display unit 24 is switched from the log history RG1 to the log history RG2. When the "specify element" button 211 is clicked again or deselected, the display on the display unit 24 switches from the log history RG2 to the log history RG1.

Next, it is a figure explaining the example 3 of a display displayed on the display part 25 using FIG.10, FIG.11. FIG. 10 is a diagram illustrating another configuration example of the display screen of the operating means. FIG. 11 is a diagram for explaining display example 3 displayed on the display unit 25. As shown in FIG.

First, the problem of the log history displayed on the display unit 24 will be described. Since the log history displayed on the display unit 24 displays the alarm occurrence item, alarm occurrence time, alarm recovery item, and alarm recovery time in chronological order, the error notification time and which device or function triggered the abnormality are displayed. You can see from the display of the log history whether it was done. Although the abnormalities of the entire broadcasting system 100 of the microwave transmission device and the transmitter of digital terrestrial broadcasting are displayed in chronological order, they are not displayed by unit (unit number) or by function, and the order in which signal data is transmitted is displayed. There was a problem that it took time to investigate the problem because it was not possible to identify the cause of the abnormality.

In this embodiment, along with the time-series change in the transmission/reception power for transmitting data, the abnormalities that are issued for the entire broadcasting system 100, for each device, for each unit, and for each function are displayed in time-series on the display section of the display screen 20. 25. This makes it possible to easily grasp the cause of the abnormality.

FIG. 10 differs from FIG. 6 in that a "time series display" button 212 is provided on the display section 21 of FIG. Other configurations and functions in FIG. 10 are the same as in FIG. 6, and descriptions thereof are omitted.

When the "time-series display" button 212 is pressed, the display changes to a display area that displays the overall abnormality of the broadcasting system 100 in time-series. The “time series display” button 212 may be placed anywhere on the display screen 20 .

Next, FIG. 11 shows an example of the display after the "time series display" button 212 is pressed.

As shown in FIG. 11, the display section 25 displays a 'whole system' button 251, a 'date and time designation section' 252, and a 'time series data designation section' 253. FIG. A 'date and time designation section' 252 is used to designate the date and time to be displayed in chronological order. A 'time-series data specification unit' 253 specifies time-series data to be displayed in time series. Along with the ``whole system'' button 251, a ``by unit'' button 261 and a ``by function'' button 262 may be provided. Along with the 'date and time designation section' 252, display range designation buttons such as a 'month display' button, a 'day display' button, a 'week display' button, and a '60 minutes' button may be provided for finely designating the display range.

In this embodiment, it is assumed that the time-series data of transmission/reception power is designated by the 'time-series data designator' 253, and the 1st day of August 8, 2XXX is designated by the 'date-and-time designator' 252. . Then, when the "whole system" button 251 is pressed, the screen of the display unit 25 displays the components of the entire system (here, MOD , TH, RH, DEM, MODEX, PA, and ANT.) and a display portion 255 for displaying the state of anomaly alarm in chronological order. As the above system configuration, the components in the STL device are a MOD (Modulator) modulator, a TH (Transmitter-Head) transmission high-frequency section, an RH (Receiver-Head) reception high-frequency section, a DEM (Demodulator) demodulator, and a MODEX (Modulation-Exciter). ) transmitter modulation exciter, PA (Power-Amplifier) transmitter power amplifier, ANT (Antenna) transmit antenna.

In this embodiment, the transmission power TP does not fluctuate, but only the reception power RP fluctuates, so it can be seen that there is no change in the state of the transmission side, but only the reception side fluctuates.

In the display portion 255, there is a time period during which only the RH and DEM issued an anomaly, which coincides with the time period during which the received power RP of the display portion 254 fluctuates. In other words, it can be understood that there was no problem up to the transmission side and that a problem had occurred in the propagation path. It can be understood that the receiving side has issued an anomaly report due to an anomaly in the propagation path. As a result, unlike the log history of the display unit 24, which is simply displayed in chronological order, it is possible to easily identify the cause of the abnormality. As a result, it becomes possible to reach the cause investigation more quickly. The display unit 25 is provided with a ``whole system'' button 251, a ``by unit'' button 261, and a ``by function'' button 262, so that time-series data can be displayed for each theme. As a result, it is possible to arbitrarily visually recognize the chronological reporting time of the failure part by theme.

Although the invention made by the present inventor has been specifically described above based on the examples, it goes without saying that the invention is not limited to the above-described embodiments and examples, and can be variously modified. .
