This monitoring device KR monitors the head amplifier 31R installed at the receiving point R, and basically has the same configuration as the monitoring device Ki described so far, and detailed description thereof is omitted. However, in the head amplifier 31R according to the present invention, the input level of each processor unit provided in the head amplifier 31R is monitored and the input signal is excessively input (for example, 85 dBμ or more). When it is detected, the output is stopped, or the presence or absence of an input signal is detected to monitor whether the broadcast wave is stopped. Therefore, by using these pieces of information, by using the monitoring devices KR and Ki, for example, by monitoring and collating the wave number input to the head amplifier 31R and the wave number or output level output from the transmitter 31G. The transmission system in the gap filler system of the present invention can be checked. That is, when the wave number information of the head amplifier 31R and the wave number information in the transmitter 31 are different, it is possible that any broadcast wave has stopped or any of the processor units constituting the head amplifier 31R has failed. If there is a part of the channel stopped from the data in the monitoring device KR of the head amplifier 31R, and if it can be confirmed that there are broadcast waves of all the channels, one of the processor units has failed. It is easy to see that

Here, the internal configuration of the monitoring device Ki will be described with reference to FIG. 8A is a block diagram showing the internal configuration of the monitoring device Ki, and FIG. 2B is a block diagram showing the internal configuration of the maintenance terminal device Tj. As shown in FIG. 8A, the monitoring device Ki, which is a monitoring server, includes a monitoring interface (IF) unit 2 including an I / O port group and an RF coaxial connector for inputting / outputting data to / from the gap filler Gi. , Providing information on the gap filler Gi to the network interface (NIF) unit 4 that transmits and receives data via the communication network N according to the TCP / IP protocol, and the monitoring client (the central management center C and the maintenance terminal device Tj), And a data processing unit 6 that executes processing for remotely controlling the gap filler Gi based on a request from the monitoring client.

Among these, the data processing unit 6 is monitoring information indicating the state of the gap filler Gi (for example, the reception level of the terrestrial digital broadcast radio wave at the reception point R, the transmission level of the radio wave to be retransmitted, the temperature in the housing, etc.) Binary data, which is information data signal-processed inside, and signal level and MER information data signal-processed by the signal processing unit 17 provided in the data processing unit 6) are monitored IF unit 2 The data collection unit 10 as a state detection unit that periodically collects collected monitoring information and sequentially collects collected monitoring information, and an abnormal situation (for example, based on the monitoring information collected by the data collection unit 10) E-mail (hereinafter referred to as "status notification") to determine whether or not a transmission / reception level abnormality, temperature abnormality, etc. A mail creation section 12 as the state notification means for creating a status notification mail generating section 12 creates, and a mail server 13 for delivering via the NIF unit 4. The NIF unit 4 is an interface for connecting to a public line, a dedicated line, the Internet, or the like, which is a communication network N. As one embodiment of the present application, for example, there is a packet communication module for a mobile phone. The NIF unit 4 is a communication network connection means.
The communication network connection means is configured to be connected to or disconnected from the communication network N by the second connection setting means indicated by the monitoring ON / OFF switch 73.

Here, the relationship among the communication network connection means, the second connection setting means, and the display means will be described. In an embodiment of the present invention, the communication network connection means is a packet communication module 4 for a mobile phone.
When the monitoring ON / OFF switch 73 as the second connection setting means is set to “OFF”, that is, the monitoring is not performed, the communication indicator lamp 59 as the display means is controlled by the packet communication module 4. Based on the signal, if the communication is not possible (for example, out of service area), it will be lit red, or depending on the communication impossible status, for example, the flashing speed is changed to display multiple statuses. . According to this, at the time of installation work of the monitoring devices Ki and KR, by setting the monitoring ON / OFF switch 73 to “OFF”, the construction worker looks at the communication indicator light 59 and monitors the monitoring devices Ki and KR. Can be installed in an optimal position with good communication conditions. In addition, as will be described in detail later, if the monitoring ON / OFF switch 73 is “OFF”, unnecessary SNMP Traps and e-mails may be frequently transmitted due to abnormalities occurring during installation work or inspection. Needless to say there is nothing. When the installation is completed in this manner, when the monitoring ON / OFF switch 73 is set to “ON”, that is, the monitoring is performed, the communication indicator 59 is communicating with the packet communication module 4 ( For example, when the electronic mail is being transmitted), for example, the green light is turned on and the light is turned off when not in communication. In addition, since various status displays can be performed with one communication indicator lamp 59, the cost can be reduced.

The data processing unit 6 also includes a monitoring target control unit 15 as an operation unit that controls the operation of the gap filler Gi via the monitoring IF unit 2 and a monitoring client (central In response to a data transmission request from the management center C or the maintenance terminal device Tj), the data extracted from the data collection unit 10 is converted into an HTML format that can be browsed by a Web browser, and the request source is transmitted via the NIF unit 4. And a Web server 16 as a maintenance function providing means for outputting a command to the monitoring target control unit 15 in response to a control request from the monitoring client via the NIF unit 4.
In the following description, a system that can control not only the monitoring by the monitoring client but also the operation of the gap filler Gi according to the control request from the monitoring client is described. Good (The explanation of the system without this function is omitted to simplify the explanation).

The data processing unit 6 includes a computer mainly composed of a CPU, ROM, and RAM, and includes a data collection unit 10, a mail creation unit 12, a mail server 13, a monitoring target control unit 15, a Web server 16, and a signal processing unit 17. Are realized as processing executed by the CPU, the address storage unit 11 is configured on a nonvolatile memory (for example, EEPROM), and the database 14 is configured on a RAM or an external storage device.

The address storage unit 11 stores at least the address of the central management center C and the address assigned to the maintenance staff in charge of the maintenance of the gap filler Gi. A status notification is transmitted to the designated address, and even after a preset time limit (for example, 15 minutes) has elapsed after the status notification is transmitted, the web page provided by the web server 16 is accessed. If not, the status notification may be retransmitted.

In addition, the status notification created by the mail creation unit 12 includes information regarding the gap filler Gi that has been monitored (installation position, model used, etc.), the type of detected abnormality, and monitoring information determined to be abnormal. There is an abnormal state notification that is an emergency notification at the time of occurrence, and an operational state notification as monitoring information that notifies the current status information about the gap filler Gi that is a monitoring target periodically or based on preset conditions, In addition to these, a URL (Uniform Resource Locator) of a Web page provided by the Web server 16 may be included. However, the URL is a hyperlink. In addition, the Web page provided by the Web server 16 is created so as to provide detailed information necessary for maintenance work, a control function of the gap filler Gi via the monitoring target control unit 15 in accordance with a request from the monitoring client. Has been.

In the monitoring device Ki according to the present invention, as the monitoring information, in addition to notifying the abnormal state notification when the abnormality occurs in the gap filler Gi, the operational state notification is further notified, for example, when the gap filler Gi is normal, This is because it is convenient because it is possible to confirm whether the monitoring apparatus itself is in an operating state (communication state), regardless of whether there is a communication abnormality or the like, regardless of the abnormality. The conditions such as timing and period when this operation state notification is "performed" are set from the connector 68 for RS-232C provided in the monitoring device main body ki when performing various initial settings of the monitoring device Ki. This can be done in advance using an external device (for example, a personal computer). In other words, the monitoring notification transmission conditions can be freely set according to the circumstances of the person in charge of maintenance, and it can be set so as not to disturb the work so that it is convenient. The connector 68 and the external device are transmission condition setting means for setting the transmission condition notification transmission condition. However, if the notification of the operation state notification is not particularly necessary, it may not be transmitted. In this case, an external device (for example, a personal computer) is used from the connector 68. This should be done in advance. In this case, the connector 68 and the external device serve as first connection setting means for setting “not perform” of the operation state notification, that is, not performing the periodic monitoring. Since the monitoring device KR is the same, detailed description is omitted (the same applies hereinafter).

Furthermore, in the monitoring device Ki of the present invention, the mail creation unit 12 sends a current state notification as monitoring information indicating the current state of the monitoring target regardless of whether there is an abnormality in the monitoring target to a central management set in advance. The address of the center C and the address of the person in charge of maintenance are set as destinations, and can be manually transmitted at an arbitrary timing by using an electronic mail via the communication network.
As described above, this manual transmission can be performed by an execution switch as manual transmission setting means for transmitting a test mail indicated by 72 in FIG. In other words, if there is no manual transmission setting means, when an attempt is made to confirm the communication state during installation work or the like, an external device (for example, the RS-232C connector 68 provided in the monitoring device main body ki) is connected. This is because the work becomes extremely difficult even considering the installation location of the gap filler Gi. In the present invention, a test mail can be transmitted by one operation of the switch 72 without a special device, and the connection with the communication network N can be easily confirmed.

Furthermore, in the monitoring device Ki of the present invention, as already described, monitoring as the second connection setting means for selecting whether to perform all SNMP Traps and e-mail transmissions “perform” or “not” An ON / OFF switch 73 and the like are provided, and the mail creation unit 12 is configured to be able to turn off all monitoring regardless of whether the monitoring target is abnormal. In other words, if there is no second connection setting means, for example, SNMP Traps and e-mails are frequently transmitted in response to an abnormality occurring during installation work or inspection, and the failure history is not stored in the database although it is not a device failure. However, the provision of the second connection setting means turns off the monitoring ON / OFF switch 73 at the time of installation work or inspection, so that even if the monitoring device detects an abnormality, an extra SNMP is detected. Traps and emails are not sent. Furthermore, if the configuration is such that the history in the database is cleared when the monitoring ON / OFF switch 73 is turned OFF, the abnormal data accumulated in the database and not sent during installation work or inspection are cleared. .

FIG. 9 shows a usage example of the display contents of the e-mail created by the mail creating unit 12. In this figure, (a) is one embodiment of the mail notification specification when an abnormality occurs, (b) is one embodiment of the mail notification specification during periodic monitoring, and (c) is the mail notification specification during a communication test. It is one Example of this.

On the other hand, as shown in FIG. 2B, the maintenance terminal device Tj has a human interface (HIF) comprising a display screen for performing various displays, keys for inputting various commands, a buzzer for generating alarms, and the like. To browse the unit 20, the NIF unit 22 that controls transmission / reception of data via the communication network N, the mail reception unit 26 that has a mail client function and receives mail via the NIF unit 22, and the Web page And a data processing unit 24 including the Web browser 28.

The data processing unit 24 is composed of a computer mainly composed of a CPU, a ROM, and a RAM, and the mail receiving unit 26 and the web browser 28 are all configured to be implemented as processes executed by the CPU. . In addition, the mail receiving unit 26 has a function as a notification unit that generates an alarm (ringing tone) in the HIF unit 20 when a mail is received.

Furthermore, the Web browser 28 provides a graphical user interface (GUI) that uses graphics for displaying information and a pointing device for input operations. The Web browser 28 provides a Web provided by the monitoring device Ki on the display screen of the maintenance terminal device Tj. When a page is displayed, a data transmission request or a control request for the monitoring device Ki is transmitted only by operating an icon on the Web page.

In the remote monitoring system configured as described above, the monitoring device Ki periodically collects monitoring information representing the state of the gap filler Gi, and creates a database representing the history of monitoring information based on the collected monitoring information. create. At the same time, the presence or absence of an abnormality is determined based on the monitoring information, and if there is an abnormality, an electronic mail (status notification) is transmitted to the central management center C and a predetermined maintenance person.

Receiving this electronic mail (status notification), the maintenance terminal device Tj notifies the maintenance staff possessing the device Tj of the reception of the mail by generating an alarm. After that, the contents of the status notification are displayed on the display screen of the maintenance terminal device Tj that has received the e-mail by the operation of the maintenance staff, and when the URL of the Web page which is one of the display items is clicked, the maintenance is performed. The terminal device Tj executes access to the monitoring device Ki. As a result, the maintenance filler Web page for the gap filler Gi is displayed on the display screen of the maintenance terminal device Tj.

Since the Web page is created using the GUI as described above, for example, by simply operating the icon button on the screen, for example, browsing history information about specific monitoring information, It is possible to remotely control the filler Gi (adjustment of transmission / reception level, etc.).

  In the monitoring device Ki, when the e-mail (status notification) is transmitted and the Web page is not accessed from the maintenance staff at the transmission destination even after the time limit has elapsed, the e-mail is resent to the maintenance staff. This is notified to the central management center C by e-mail.

As described above, in the remote monitoring system of the present embodiment, the monitoring device Ki that detects the abnormality of the gap filler Gi is not only the central management center C but also the maintenance person in charge of the maintenance of the gap filler Gi. Even e-mail (status notification) is sent directly.

Therefore, according to the remote monitoring system of the present embodiment, the status notification addressed to the maintenance staff can be promptly delivered without going through the central management center C, so that the abnormality of the gap filler Gi can be dealt with promptly. In addition to the above, even if the function of the central management center C is down for some reason, it is possible to reliably notify the maintenance staff of the abnormality of the gap filler Gi and improve the reliability of the system.

Further, in the remote monitoring system of this embodiment, when the monitoring device Ki transmits a status notification but there is no access to the Web page from the maintenance staff, this is notified to the central management center C. Therefore, even if the maintenance staff cannot know the reception of the status notification for some reason, the countermeasure can be taken through the central management center C, and the reliability of the system can be improved. Further improvement can be achieved.

In the present embodiment, the maintenance terminal device Tj only needs to have a mail client function and a Web browser function, and a mobile phone or the like having these functions can be used as the maintenance terminal device Tj. In addition, there is no need to create dedicated software, and a system can be constructed easily and inexpensively. In addition, since the information is displayed on the Web page using the GUI, the maintenance person can easily operate without having to master complicated operations such as command input and special usage methods, so the maintenance terminal device The work efficiency of maintenance work using Tj can be improved.

Furthermore, in the remote monitoring system of the present embodiment, when the status notification is first received via the maintenance terminal device Tj, monitoring information about the current state of the gap filler Gi can be obtained, and then the Web page is browsed. Thus, detailed information necessary for identifying the cause of the abnormality, such as a history of monitoring information, can be obtained. Accordingly, the maintenance staff can take an appropriate response to the abnormality that has occurred. For example, when temperature abnormalities occur in the housing, the history of temperature changes in the housing is referred to determine whether it is due to external factors such as solar radiation or due to component heat generation based on secular changes. It becomes possible to do.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist of the present invention. For example, in the above embodiment, the Web server 16 provides data converted to the HTML format, but may provide data converted to the XML (Extensible Markup Language) format. However, it is necessary to add a function for converting data in XML format into HTML format using a style sheet on the monitoring client side browsing the Web page.

In this case, by preparing a style sheet suitable for the maintenance terminal device Tj possessed by the maintenance staff, it is possible to display easily according to the screen size, and even if the same data is used (for example, the maintenance terminal device Tj, the center It is possible to perform different displays depending on which one of the management centers C is used.

In the above-described embodiment, the monitoring information is supplied and the monitoring target is controlled by using the function of the Web server. For example, as shown in FIG. 3, the monitoring device uses SNMP (Simple Network Management Protocol). Even if the monitoring device Ki is monitored and controlled by configuring Ki as an SNMP agent, the central management center C and the maintenance terminal device Tj as an SNMP manager, and a database provided in the monitoring device Ki as a management information base (MIB). Good.

In this case, when the SNMP manager changes the MIB value, the monitoring target control unit 15 may execute control corresponding to the changed MIB value. In addition, a notification when an abnormality is detected may use a TRAP function that can be transmitted spontaneously by an SNMP agent instead of an e-mail.

Further, when it is desired to construct a system at a relatively low cost, as shown in FIG. 2, the system may simply transmit a status notification to a mobile phone as a maintenance terminal device Tj that is a management device.
