  By the way, in a data communication control system in which a plurality of wireless communication network areas and a plurality of Web terminals are connected via a Web server, the station status of the wireless communication network area is inquired from the Web terminal and displayed on the Web terminal. There is.

  In this case, when a facility status inquiry is made to a plurality of wireless communication network area stations simultaneously from a plurality of Web terminals, a large amount of monitoring status is sent as response information to the Web server. However, there is no effective solution to this problem in the past.

  And even if it applies the above-mentioned prior art to this problem, since it controls data communication using a port management table, it is necessary to prepare a large-scale port management table beforehand. There is a problem.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a remote monitoring system having a simple configuration that can shorten the time required for inquiring about the equipment state.

  The remote monitoring system of the present invention creates transmission threads corresponding to a plurality of wireless communication network areas when a Web server is activated, and simultaneously creates a plurality of wireless communication network area stations from a plurality of Web terminals. When a large amount of event information such as a monitoring state notification is received by an equipment state inquiry, the event information is passed to a transmission thread in the wireless communication network area. The transmission thread transmits the event information to the Web terminal that is accessing the wireless communication network area.

  The effect of the present invention is that even when a plurality of wireless communication network inquiries are made simultaneously from a plurality of web terminals, the equipment status information is displayed on the web terminal without delay inside the web server. It will be possible.

  The reason is that the Web server can process the communication time with each Web terminal in parallel by creating a transmission thread for transmitting the equipment status information from the Web server to the Web terminal in one-to-one correspondence with the wireless communication network area. This is because the response display time for a plurality of Web terminals can be shortened.

  The remote monitoring system of the present invention is a remote monitoring system that inquires about the state of station facilities in a plurality of wireless communication network areas from a plurality of web terminals. A generated wireless communication network area-to-one wireless communication network transmission thread, an inquiry function software generated corresponding to an inquiry-requested wireless communication network area, a wireless communication network area transmission thread, and the inquiry function software And a web interface unit that takes an interface.

  The inquiry function software transmits the request signal to the remote monitoring device in the wireless communication network area designated based on the inquiry request of the station equipment status from the web terminal, and receives the response information and the equipment status information from the remote monitoring device. When received, it writes to the built-in buffer.

  The web interface part sends the response information and alarm signal in the buffer of the inquiry function software to the corresponding wireless communication network transmission thread, and the wireless communication network transmission thread sends the equipment status to the web terminal of the inquiry request for the station equipment status Information is transmitted.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  Electric power companies, communication companies, and the like have established communication networks across a plurality of prefectures, and in such cases, many manage the communication networks for each prefecture from a maintenance request. An area where each prefecture maintains and manages a communication network constructed across a plurality of prefectures is called a wireless communication network area.

  Management is performed by ascertaining the status of station equipment such as multiple radio equipment, synchronous terminal equipment, switching equipment, DC power supply equipment, air conditioning equipment, and generators installed in office buildings in the wireless communication network area. For example, in the case of a multiplex radio, the state of the station facilities is an operating state such as which one of the transmitters and receivers of No. 1 and No. 2 is operating, and alarms such as a decrease in transmission level and reception level. Or the like.

  The station equipment state is usually sent to the center station by the remote monitoring device, but there are cases where the state data is lost due to quality deterioration or convergence of the transmission line of the remote monitoring device. In addition, there are cases where it is necessary to display the equipment status of the station again after the work such as renovation at the site. In such a case, the station is specified and the station equipment status is inquired and confirmed.

  Now, referring to FIG. 1 showing a block diagram of an embodiment of the present invention, this remote monitoring system includes six wireless communication network areas 141 to 146 and nine Web terminals 111 to 119 via a Web server 150. Connected. The Web terminals 111 to 119 are monitoring control terminals for the operator to inquire about the station facility status of the wireless communication network areas 141 to 146.

  In response to the inquiry about the station equipment status from the Web terminals 111 to 119, the Web server 150 acquires information on the station equipment status of the designated wireless communication network area and returns it to the Web terminal that is the source of the inquiry request. In FIG. 1, the Web server 150 includes three FOs 131 to 133, an FO to Web interface unit 121, and six wireless communication network transmission threads 101 to 106 that correspond one-to-one with the wireless communication network areas 141 to 146. I have.

  FO is an abbreviation for Function Object and is software having an inquiry function. When the operator makes an inquiry request for the station equipment status from the Web terminals 111 to 119, the FO transmits the inquiry request signal to the remote monitoring device designated based on this request. When the remote monitoring device receives the inquiry request signal, it returns response information to the FO of the transmission source, and thereafter, information on the station equipment status (alarm, active / standby status) based on the requested content. Hereinafter referred to as “equipment state information”).

  The FO writes this information in a built-in buffer. Three FOs 131 to 133 indicate that a request for an inquiry about the station equipment status for the three wireless communication network areas is received. The response information is a signal for notifying the Web server 121 that the remote monitoring apparatus has received the inquiry request signal normally. If no response information is returned, the FO times out and the Web server 121 notifies the Web terminal that the inquiry request has ended abnormally.

  The wireless communication network transmission threads 101 to 106 are generated in one-to-one correspondence with the wireless communication network areas 141 to 146. When the Web server 121 receives an inquiry request about the station equipment state from the Web terminals 111 to 119, the Web server 121 passes the event to the wireless communication network transmission thread corresponding to the wireless communication network area. Further, the wireless communication network transmission thread transmits the equipment state information distributed by the FO to Web interface unit 121 from the FO presence to the corresponding request source Web terminal.

  The FO to Web interface unit 121 interfaces with the FOs 131 to 133 and the wireless communication network transmission threads 101 to 106.

  Next, the operation of the remote control system configured as described above will be described.

  When the Web server 121 is activated, wireless communication network transmission threads 101 to 106 that are in one-to-one correspondence with the wireless communication network areas 141 to 146 are generated. Assume that the Web terminals 111 and 112 simultaneously make an inquiry request for the state of the building facilities to the wireless communication network area 141, the Web terminal 113 to the wireless communication network area 142, and the Web terminal 114 to the wireless communication network area 143.

  In the Web server 121, FOs 131, 132, and 133 are generated corresponding to the wireless communication network areas 141, 142, and 143, respectively. The wireless communication network transmission threads 101, 102, and 103 pass the inquiry request event of the station equipment status to the FOs 131, 132, and 133 via the FO to Web interface unit 121, respectively. The FOs 131, 132, and 133 transmit inquiry request signals to the remote monitoring devices in the wireless communication network areas 141, 142, and 143, respectively.

  These remote monitoring apparatuses collect equipment state information and transmit response information and equipment state information to the FOs 131, 132, and 133. The FOs 131, 132, and 133 buffer this information and pass them all at once to the FO to Web interface 121. The FO to Web interface 121 sorts the sent equipment state information for each of the wireless communication network areas 141, 142, and 143, and transmits them to the transmission threads 101, 102, and 103, respectively.

  The wireless communication network transmission threads 101, 102, and 103 transmit the passed equipment state information to the Web terminals 101 and 102, 103, and 104. This transmission can be performed independently and in parallel.
