Description

The present invention relates to an alarm display method for displaying an alarm occurrence situation in a monitored system.

An example of a system that is subject to remote control and monitoring is a micro receiving base station system that includes fixed wireless transmission between base stations using FPUs (Field Pick-up Units). FIG. 1 shows a system example of a micro receiving base station system. In the following, an example of transmitting materials from transmission point A (11) and transmission point B (14) to head office (13) will be described.

A material from a transmission point A (11) far from the head office is wirelessly transmitted to the head office (13) through a base station (12) as follows. First, a transmitter (11-1) at a transmission point A (11) converts a material into a microwave signal that can be wirelessly transmitted, and transmits radio waves from a portable antenna (11-2). Here, the transmitter (11-1) encodes an SDI (Serial Digital Interface) signal into a TS (Transport Stream) signal, which is a fixed-length packet frame format used for transmission in the FPU, and converts it to After being modulated into an intermediate frequency signal, it is frequency-converted into a microwave band and transmitted to a portable antenna (11-2).

Radio waves transmitted from transmission point A (11) are received by a rotating antenna (12-1) in a base station (12) and sent to a fixed receiver (12-2). Here, the fixed receiver (12-2) has a function of frequency-converting a microwave band signal into an intermediate frequency signal, demodulating it into a TS signal, and decoding it into an SDI signal. However, the fixed receiver (12-2) in the base station (12) only needs to have the function of converting to a TS signal with minimal signal degradation. The obtained TS signal is sent to a fixed transmitter (12-3) and transmitted by radio waves from a fixed antenna (12-6). The fixed transmitter (12-3) in the base station (12), like the fixed receiver (12-2), should at least have the function of converting the TS signal into the microwave band.
Radio waves transmitted from the base station (12) are received by the fixed antenna (13-1) of the head office (13) and decoded into SDI signals by the fixed receiver (13-2) and the decoder (13-5). , is sent to the main line.

In addition, the material from the transmission point B (14) located at a short distance from the head office (13) passes through the transmitter (14-1) and is transmitted from the portable antenna (14-2) directly to the head office (13). It is received by a rotating antenna (13-3), decoded by a receiver (13-4) and a decoder (13-5), and sent to the main line.

In wireless transmission using this system, it is important how efficiently the radio waves from the transmission point can be received at the base station (12). That is, the direction of the rotating antenna (12-1) in the base station (12) must be changed according to the position of the transmission point. Therefore, in the micro receiving base station system, the rotating antenna (12-1) is a rotating mount that can be rotated by remote control from the head office (13). The control and monitoring method is as follows.

In the head office (13), the control packet transmitted from the operation terminal (13-10) to the network is received by the control terminal station (13-9) and converted into a serial signal. Here, it is of course possible to connect a plurality of operation terminals (13-10) and a plurality of control terminal stations (13-9) to the network, specify the destination of transmission/reception by each device ID, and transmit and receive. . The serial signal is further modulated into, for example, an analog signal by the modulator/demodulator (13-8) and transmitted to the base station (12).
An analog signal transmitted from the headquarters (13) is received by the modulation/demodulation unit (12-5) in the base station (12), demodulated into a serial signal, and transmitted to the controlled terminal station (12-4). The controlled terminal station (12-4) decodes the control signal and controls the rotating antenna (12-1).

Monitoring information such as the angle of the rotating antenna (12-1) is sent as a monitoring signal to the controlled terminal station (12-4). The controlled terminal station (12-4) transmits the information as a serial signal to the modulator/demodulator (12-5), which modulates it into an analog signal, for example, and sends it to the head office (13). to send.
A modulation/demodulation unit (13-8) in the head office (13) demodulates the received signal into a serial signal and transmits the serial signal to the control terminal station (13-9). The control terminal station (13-9) decodes the received serial signal and transmits a monitor packet to the network. The operation terminal (13-10) receives the monitoring packet and displays it as information on the terminal.

As described above, it is possible to control and monitor the rotating antenna (12-1) in the base station (12). 12-2) and fixed transmitter (12-3) reception / transmission level, transmission / reception channel (frequency band), modulation method, transmission output, decoding method, contact selection of signal switcher, signal multiplexing / demultiplexing device Signal input/output selection is the same as that for the rotating antenna (12-1), operating terminal (13-10) - control terminal station (13-9) - controlled terminal station (12-4) - control device can be controlled and monitored by a series of signaling of
Also, in the case of direct transmission to the head office like material transmission from transmission point B (14), using the signal transmission path of operation terminal (13-10) - control terminal station (13-9) - control device, It is possible to control and monitor devices such as a rotating receiving antenna device (13-3) and a receiving unit (13-4) existing in the head office (13).

In addition, in this system, TMCC (Transmission and Multiplexing Configuration) including transmission parameters such as reception frequency and modulation scheme in the receivers (12-2, 13-4) is used as reference information for adjusting the direction of the receiving antenna. Control; transmission multiplex control signal) information, reception level, margin degree, BER (Bit Error Rate), MER (Modulation Error Ratio), delay profile, data such as constellation A method of superimposing on a TS signal and transmitting it to the head office (13), separating it by an information generating section (13-6), editing it by an information editing section (13-7), and displaying it on an operation terminal (13-10). There is

As prior art in such a technical field, there are the following. For example, Japanese Patent Application Laid-Open No. 2002-200001 discloses an invention that provides support for avoiding shooting obstacles that make it impossible to shoot a shooting target due to obstacles such as terrain and buildings. Further, Japanese Patent Laid-Open No. 2002-200000 discloses an invention that makes the display of transmission paths and faulty areas more clear, and assists the user in determining whether or not transmission is possible more quickly and effectively.

1 is a diagram showing a system example of a micro receiving base station system; FIG. It is a figure which shows the operation screen example of the conventional remote control monitoring system. It is a figure which shows the example of the operation screen of the remote control monitoring system which concerns on one Embodiment of this invention.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 3 shows an example of an operation screen of the remote control monitoring system according to one embodiment of the present invention. The operation screen in FIG. 1 assumes the operation of a micro-receiving base station system in particular, and simply represents the system shown in FIG. Such an operation screen is displayed, for example, on the operation terminal (13-10) of the head office (13).

The basic configuration of the operation screen according to this proposal is the same as that of the conventional one (Fig. 2). 13) and a head office facility details window (22) that schematically represents the facility configuration.

The base station equipment details window (21) includes a rotating antenna control button (21-1) corresponding to the rotating antenna (12-1) and a fixed receiver (12) as display elements representing the equipment configuration of the base station (12). -2) corresponding to the fixed receiver control button (21-4), the fixed transmitter control button (21-6) corresponding to the fixed transmitter (12-3), and the fixed antenna (12-6). A fixed antenna display unit (21-9), a configuration equipment control button (21-10) corresponding to the controlled terminal station (12-4), and a modem display unit (12-5) corresponding to the modem unit (12-5) 21-12).

In addition, a rotating antenna control button (21-1), a fixed receiver control button (21-4), a fixed transmitter control button (21-6), a component equipment control button (21-10), a modem display unit (21 -12), there are a rotating antenna alarm display section (21-2), a receiver alarm display section (21-5), a fixed transmitter alarm display section (21-7), a component equipment alarm display section (21- 11), a modem unit and an alarm display unit (21-13) are provided respectively. These alarm display units light up in a predetermined color (for example, red) when an alarm occurs in the corresponding equipment. Further, near the rotary antenna control button (21-1), a rotary antenna polarization plane display section (21-3) for displaying the state of the polarization plane of the rotary antenna (12-1) is also provided. A fixed transmitter output level display section (21-8) for displaying the output level of the fixed transmitter (12-3) is also provided near the fixed transmitter control button (21-6).

The head office facility details window (22) includes a fixed antenna display section (22-1) corresponding to the fixed antenna (13-1) and a fixed receiver (13-2) as display elements representing the facility configuration of the head office (13). ) corresponding to the fixed receiver control button (22-2), the rotating antenna (13-3) corresponding to the rotating antenna control button (22-4), and the receiver (13-4) corresponding to the receiver control a button (22-6), a modulation/demodulation unit display unit (22-8) corresponding to the modulation/demodulation unit (13-8), and a configuration equipment control button (22-10) corresponding to the control terminal station (13-9) have

In addition, fixed receiver control button (22-2), rotating antenna control button (22-4), receiver control button (22-6), modem unit display unit (22-8), equipment control button (22-10) ), there are a fixed receiver alarm display section (22-3), a rotating antenna alarm display section (22-5), a receiver alarm display section (22-7), and a modem section alarm display section (22-9). , a component equipment alarm display unit (22-11) is provided. These alarm display units light up in a predetermined color (for example, red) when an alarm occurs in the corresponding equipment.

The main feature of the operation screen according to this proposal is that, in addition to the total alarm display by the alarm display unit as described above, a pop-up display of a graph showing the breakdown of alarms generated in equipment selected by user operation is performed. For example, assume that a failure occurs in the modem (12-5) of the base station (12). In this case, the modem unit alarm display unit (21-13) in the base station facility details window (21) lights up. As a result, the user viewing the screen of the operating terminal (13-10) can understand that a fault has occurred in the modem (12-5) of the base station (12). At this time, the user moves the cursor (31-1) of the operation terminal (13-10) to overlap the modem unit display unit (21-12), and the alarm breakdown screen appears near the cursor (31-1). (31-2) is popped up.

On the alarm breakdown screen (31-2) illustrated in FIG. 3, four alarm items such as FAN alarm, power supply 1 alarm, power supply 2 alarm, and communication alarm are displayed as breakdowns of alarms generated in the modem unit (12-5). The alarm duration of is displayed graphically. Therefore, the user can not only check the status of alarm occurrence in the modem unit (13-8), but also can see specific details through the alarm breakdown screen (31-2) that pops up when the modem unit (13-8) is selected. It is possible to grasp the content of various alarms.

In addition, the alarm breakdown screen (31-2) in this example targets each alarm generated in the modem unit (12-5) within 10 minutes before and after the alarm confirmation time, and the continuation of each alarm. Time is represented on a common timeline. In this way, by expressing the duration of a plurality of alarms within a predetermined time interval in the same time-series graph, the user can intuitively grasp the time-series occurrence status of each alarm. Therefore, it is possible to transmit more information in a short time than before when confirming the situation and transmitting information between the user and the person in charge of the manufacturer.

Here, the alarm confirmation point is designated by the user when the user selects the facility to be displayed as a pop-up (in this example, when the cursor is placed on the facility). When the user specifies the alarm confirmation time point, the initial value of the alarm confirmation time point (for example, the current time or the time that is a predetermined time before the current time) can be set in advance. It is also possible to simplify the designation. Also, the length of the time interval starting from the alarm confirmation point may be set in advance or may be designated by the user.

In addition, in the alarm breakdown screen (31-2) of this example, the graph color of the alarm item for which the alarm continues from the point of alarm confirmation to the current time is set to a different color (for example, red) from other alarm items. is becoming This makes it possible to grasp at a glance the alarm item in which a failure has occurred at the present time, so that it is possible to further facilitate identification of the cause when a failure occurs.

In addition, in the event that an alarm occurs, if the event is treated as a serious broadcast accident that could lead to the suspension of broadcasting, if it is the parent station, if the broadcasting suspension continues for 15 minutes, the obligation to report to the Ministry of Internal Affairs and Communications will occur. . Therefore, alarms that cause such reporting obligations are registered in advance as important alarms in the system, and when an important alarm occurs, the alarm display part of the corresponding equipment on the operation screen and the alarm breakdown screen ( A pop-up window) frame or characters may be emphasized. As a result, it is possible to alert the user to the occurrence of the important alarm, and prompt action for early recovery.

As described above, in the remote control monitoring system of this example, the operation terminal (13-10) at the head office (13) operates on the operation screen displaying the system diagram showing the facility configuration of the micro-receiving base station system to be monitored. , the alarm generation status of each facility is displayed, and when the facility with the alarm generated is selected by the user's operation on the operation screen, an alarm breakdown screen (31-2) showing the breakdown of the alarm is popped up. In this alarm breakdown screen (31-2), when there are multiple alarms generated in the selected facility, the duration of each of these multiple alarms is displayed in graphs on a common time axis.

According to such a configuration, it is possible not only to check the alarm occurrence status of each facility on the operation screen displaying the system diagram, but also to easily grasp the specific alarm content and its duration. In addition, it is possible to visually confirm the series of occurrence times of the respective alarms. As a result, it is possible to more easily identify the cause of failure than the conventional method. Furthermore, since it is possible to check the specific alarm content and its duration without extracting the alarm log from the equipment, the user can estimate the cause of the alarm by himself/herself before asking the equipment manufacturer. For example, if an alarm has occurred for all alarm items, it can be assumed that the power source is the cause, so the user can confirm and deal with it. Therefore, it is possible to shorten the time required for failure recovery compared with the conventional system.

In the above example, the alarm details screen is displayed as a pop-up when the cursor is placed on the display of the facility for which the alarm details screen is desired to be displayed. good. For example, the alarm breakdown screen may be displayed as a pop-up when the user clicks the display section of the facility for which the alarm breakdown screen is desired to be displayed. Further, the position where the alarm breakdown screen is popped up is not limited to the position near the cursor (that is, the position near the facility selected by the user's operation), and the popup may be displayed at another position. In this case, in order to facilitate understanding of the relationship between the selected facility and the pop-up alarm breakdown screen, an auxiliary display such as connecting these with a line may be further performed.

Although the present invention has been described above based on one embodiment, it goes without saying that the present invention is not limited to the configuration described here, and can be widely applied to systems with other configurations.
In addition, the present invention provides, for example, a method including technical procedures related to the above processing, a program for causing a processor to execute the above processing, and a storage medium storing such a program in a computer-readable manner. is also possible.

It should be noted that the scope of the invention is not limited to the illustrated and described exemplary embodiments, but includes all embodiments that achieve equivalent effects for which the invention is intended. Moreover, the scope of the invention may be defined by any desired combination of the specific features of each and every disclosed feature.
