Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a monitoring system that monitors the state of each component device in a two-way joint reception facility, and particularly relates to a monitoring system that uses a mobile communication device such as a mobile phone or a PHS.
[0002]
[Prior art]
For example, a status monitor device is known as a device that monitors the state of each component device of the joint reception facility. In this status monitor device, a status monitor is provided for each component of the bidirectional joint reception facility, for example, each bidirectional amplifier. These status monitors monitor the operating state of the corresponding bidirectional amplifier, and transmit the monitoring result to the center apparatus provided on the head end side of the bidirectional joint reception facility by an upstream signal. The center device monitors the operating state of each bidirectional amplifier.
[0003]
[Problems to be solved by the invention]
In this status monitor device, it is possible to know which bidirectional amplifier has a failure in the center device. However, the worker dispatched to the installation location of the faulty bidirectional amplifier cannot know the current status data about the bidirectional amplifier at the installation location without using a measuring instrument. For the purpose of fault repair, there are times when it is desired to know the state of the bidirectional amplifier at the front stage (head end side) or the rear stage (terminal side) of the faulty bidirectional amplifier. In order to know this, the worker himself / herself goes to the installation location of the upstream and downstream amplifiers at a remote location, or calls the monitoring staff stationed at the installation location of the center device, and The state of the bi-directional amplifier needs to be read from the center device and notified. For this reason, when a failure occurs in the two-way joint reception facility, it cannot be promptly restored.
[0004]
It is an object of the present invention to provide a monitoring system for a joint reception facility that can know the operating state of each component device of the interactive joint reception facility at a position away from the center device and can be promptly restored in the event of a failure. Objective.
[0005]
[Means for Solving the Problems]
The interactive joint reception facility monitoring system according to the present invention includes a center device. In the center apparatus, state data representing the state of a predetermined component device of the interactive joint reception facility is transmitted from the predetermined component device via the interactive joint reception facility. The predetermined component device includes, for example, a bidirectional amplifier, but various other devices can be used as long as the device can be equipped with a so-called status monitor device. There may be only one predetermined component device, but of course, a plurality of devices may be used. This monitoring system has a server capable of transmitting the status data from the center device via the Internet. The server and the mobile communication device are connected via the Internet, and the mobile communication device receives the data via the Internet. A mobile phone or a PHS can be used as the mobile communication device. Since the server transmits data via the Internet, it is desirable that the server be a WEB server capable of transmitting hypertext information.
[0006]
According to this monitoring system, when the mobile communication device is connected to the server via the Internet, the state data can be transmitted from the center device to the mobile communication device via the Internet. Therefore, the worker carrying the mobile communication device can know the contents of the status data of the constituent devices even when the worker is away from the center device.
[0007]
The mobile communication device includes designation information input means for designating a desired one of the constituent devices . The designation information input means inputs identification information such as a number, an address or a name assigned to a desired component device, for example, to the mobile communication device. In this case, the server transmits the status data of the component device designated from the mobile communication device by the designation information input means to the mobile communication device via the Internet.
[0008]
With this configuration, the worker carrying the mobile communication device at a position away from the center device, for example, the malfunctioning component device, specifies the identification information of the malfunctioning component device. When input to the mobile communication device by the input means, it is possible to know the contents of the status data of the failed component device without using a measuring instrument.
[0009]
Further, the mobile communication device may include component device designation means located in the preceding and succeeding stages of the designated component device. This designation means does not input the identification information of each component device, but generates the identification information of the preceding or subsequent component device based on the identification information of the component device already designated by the input means. In this case, the server sends the status data of the preceding and succeeding component devices of the designated component device to the mobile communication device via the Internet according to the operation of the component device specifying means located in the preceding and succeeding devices. And transmit.
[0010]
With this configuration, a worker in the vicinity of the failed component device moves to the installation location of the preceding or subsequent component device, connects the measuring instrument, or bothers to call the center device installation location. As a result, it is possible to know the operating states of the component devices in the previous stage and the subsequent stage of the failed component device without having to be contacted by the monitor of the center apparatus. In addition, it is not necessary to input identification information, such as an address, number, or name, of the former and subsequent components, and only a simple operation of operating the designation unit is required.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The interactive joint reception facility monitoring system according to one embodiment of the present invention is used in a bidirectional joint reception facility 2 as shown in FIG. The two-way joint reception facility 2 has a head end 4 from which downstream signals including terrestrial television broadcast signals, satellite broadcast signals, satellite communication signals, and the like are transmitted to the transmission line 6. A downlink signal is transmitted from the head end 4 to a large number of terminal devices (not shown) via the transmission path 6. In this transmission line 6, a plurality of bidirectional joint auditory facility components, for example, bidirectional amplifiers are arranged. FIG. 1 shows only the bidirectional branch amplifier 8 among these bidirectional amplifiers. A branching device 10 is also provided in the transmission line 6.
[0014]
Although not shown, these bidirectional amplifiers 8 are provided with a status monitor. The status monitor monitors the operation state of each bidirectional amplifier 8 and transmits state data representing the monitoring result to the head end 4 as an upstream signal via the transmission line 6. This state data is transmitted to the status monitor center device 12 provided on the head end 4 side.
[0015]
As the state data, data representing the open / closed state of the lid of the casing of the bidirectional amplifier 8, data representing whether the operating power source is a commercial power source or an inverter, data representing the presence or absence of water intrusion into the housing, Data indicating whether the upstream branch amplification unit is in a state of allowing or preventing the upstream signal from passing, data indicating whether the upstream trunk amplifier unit is in a state of passing or preventing the upstream signal, downstream amplification Data indicating whether the unit is operating in AGC or MGC, data indicating the output level of the downlink pilot signal, data indicating AC power supply voltage, data indicating DC power supply voltage, data indicating temperature in the housing, housing There are data that shows the humidity in the body.
[0016]
The status data transmitted to the status monitor center device 12 is stored in the database 14. Each bidirectional amplifier 8 is assigned an amplifier number, and each state data is stored in the database 14 in correspondence with the amplifier number. In the database 14, every time the status data of each bidirectional amplifier 8 is changed, the contents of the status data stored in the database 14 are also updated. That is, the data in the database 14 is updated as needed. Using the database 14, the status monitor center device 12 monitors the operating state of each bidirectional amplifier.
[0017]
The database 14 is also used in a server, for example, a WEB server 16. That is, the database 14 is shared by the status monitor center device 12 and the WEB server 16. The WEB server 16 has a dedicated home page. This home page can be accessed from a mobile communication device, for example, a mobile phone 20, via the Internet 18. By viewing this home page on the mobile phone 20, the status data of each bidirectional amplifier 8 can be obtained from the status monitor center device. Even if the mobile phone 20 is located away from the mobile phone 20, the owner of the mobile phone 20, for example, a worker can know it.
[0018]
For example, the URL of the WEB server 16 is input from the mobile phone 20 to access the login page of this home page. When the user name and password are input, a screen for inputting the amplifier number of the bidirectional amplifier 8 whose status data is desired to be displayed is displayed on the mobile phone 20 as shown in FIG. Here, by operating an operation button on a designated information input means, for example, the cellular phone 20 to input an amplifier number, and operating an operator on the screen displayed as transmission, the status data of the amplifier corresponding to the amplifier number 2 is taken out from the database 14 by the server and displayed on the screen of the mobile phone 20 as shown in FIG. In this state, when a specified unit, for example, a predetermined one of the operation buttons of the cellular phone 20 is operated, the state data of the amplifier immediately preceding the amplifier to which the amplifier number has been previously input is displayed. Similarly, when another predetermined one of the operation buttons of the specifying means, for example, the cellular phone 20 is operated, the status data of the amplifier immediately after the amplifier to which the amplifier number has been previously input is displayed. Thus, in order to know the state data of the preceding and succeeding amplifiers, it is not necessary to bother to input the amplifier numbers of the preceding and succeeding amplifiers.
[0019]
In order to display the status data on the mobile phone 20 in this way, the WEB server 16 operates according to flowcharts as shown in FIGS. The WEB server 16 receives data via the Internet 18 and analyzes the data (step S2). Then, it is determined whether the analyzed data is a request for access to the login page (step S4). If access is requested, data for displaying a login page on the mobile phone 20 is transmitted via the Internet 18 (step S6), and the process returns to step S2.
[0020]
If it is determined in step S4 that it is not an access to the login page, it is determined whether the data is a request for login (step S8). That is, a user name and a password are input, and it is determined whether or not the password matches a predetermined one. If it is a log-in request, the user logs in (step S10), transmits the page data for inputting the amplifier number to the mobile phone 20 via the Internet 18 (step S12), and returns to step S2. Thereby, a display as shown in FIG. 2A is made on the screen of the mobile phone 20.
[0021]
If it is determined in step S8 that the request is not a login request, it is determined whether login has already been performed (step S14). If it is determined that the user is logged in, it is determined whether transmission of the status data of the amplifier corresponding to the amplifier number is requested from the mobile phone 20 (step S16). That is, in the screen shown in FIG. 2A, it is determined whether the amplifier number is input to the amplifier number input window on the screen of the mobile phone 20 and the transmission operator displayed on the screen is operated. When transmission is requested, the status data of the corresponding amplifier is transmitted to the mobile phone 20 via the Internet 18 (step S18), and step S2 is executed. By executing step S18, each status data is displayed on the screen of the mobile phone 20 as shown in FIG. Therefore, a worker who has been informed that a certain bidirectional amplifier is faulty does not have to use a measuring instrument when arriving at the installation location of the bidirectional amplifier or by the time it arrives. The current state of the amplifier can be known.
[0022]
If it is determined in step S14 that the user is not logged in, a message is transmitted (step S20), and step S2 is executed. This message is for prompting login.
[0023]
If it is determined in step S16 that it is not a request for transmitting the status data of the amplifier corresponding to the amplifier number, it is determined whether it is a request for transmitting the status data of the subsequent amplifier as shown in FIG. 4 (step S22). That is, it is determined whether a predetermined operation button of the mobile phone 20 has been operated. If it is a request to transmit the status data of the subsequent amplifier, the status data of the one-stage bidirectional amplifier of the bidirectional amplifier of the amplifier number input in step S12 is transmitted to the mobile phone 20 via the Internet 18 (step S24). ), The process returns to step S2. By executing step S24, the cellular phone 20 displays the state of the subsequent bidirectional amplifier.
[0024]
If it is determined in step S22 that it is not a data request for the subsequent amplifier, it is determined whether it is a transmission request for status data of the previous amplifier (step S26). That is, it is determined whether another predetermined operation button of the mobile phone 20 has been operated. If it is a request to transmit the state data of the previous amplifier, the state data of the bidirectional amplifier immediately preceding the bidirectional amplifier with the amplifier number input in step S12 is transmitted to the mobile phone 20 (step S28), and the process proceeds to step S2. Return. By executing step S24, the cellular phone 20 displays the state of the subsequent bidirectional amplifier.
[0025]
As described above, the state data of the bidirectional amplifiers before and after the specific bidirectional amplifier can be known at the installation location of the specific bidirectional amplifier. Therefore, before starting repair of the fault, it is not necessary to make a phone call to the installation location of the status monitor center device at the installation location of the specific bidirectional amplifier to check whether there is an abnormality in the upstream and downstream bidirectional amplifiers. Can know. In addition, after repairing the failure, call the installation location of the status monitor center device one by one at the installation location of the bi-directional amplifier that repaired the failure to check whether the upstream and downstream signals are transmitted normally to the upstream and downstream stages, respectively. You can know without it. In particular, when the status data is changed, the data in the database 14 is updated along with the change, so that it is possible to know the statuses of the upstream and downstream amplifiers after the repair is completed.
[0026]
If it is determined in step S26 that it is not a data request for the pre-stage amplifier, it is determined whether it is a logout request (step S30). If it is a logout request, the user logs out (step S32), transmits a message (step S34), and returns to step S2. This message is for logging out.
[0027]
If it is determined in step S30 that it is not a logout request, a message is transmitted and step S2 is executed. This message indicates that there is no status data corresponding to the input amplifier number.
[0028]
In the above embodiment, a mobile phone is used, but a PHS can be used instead. In the above embodiment, a specific operation button of the cellular phone is used to designate the latter amplifier and the former amplifier. However, the operator for the former designation and the latter designation operator are displayed on the screen of the cellular phone. The operator may be displayed, and the operation button may be appropriately operated to move the cursor over these operators. In the above embodiment, the amplifier number is input, but the address of the status monitor provided in each bidirectional amplifier may be input. Further, although the operational state of all the bidirectional amplifiers is monitored by the status monitor, the operational state of a predetermined one of the bidirectional amplifiers may be monitored by the status monitor. As long as the status monitor can be attached to devices other than the bidirectional amplifier among the components of the bidirectional joint reception facility, these devices may be monitored. In the above embodiment, the amplifier number and each state data are displayed as shown in FIG. 2B, but the location of the amplifier corresponding to the amplifier number may also be displayed. This location can also be displayed when displaying the status data of the amplifiers at the front and rear stages.
[0029]
【The invention's effect】
As described above, according to the present invention, since the operation state of each component device of the interactive joint reception facility can be confirmed by the mobile communication device, the measuring device is used one by one, or the center device is installed. It is not necessary to contact the operation state grasped by the center device. In addition, for example, the state of the component devices before and after the failed component device can be known without going to these installation locations.
