Abstract

DC60 (27/12/53) The monitoring and control system includes a central main line system (209) installed in the sales office and a central backup system (208). The monitoring and control system also includes the function of linking the terminals of different substations, which, in the event of an abnormality in the communication channel intended for each individual substation terminal, will connect the substation terminal to the central main line system (or central backup system) and issue commands to the different substation terminals to connect and communicate with the central main line system (or central backup system) instead of the substation terminals. With this structure, the central main line system monitors and controls the switches that will be monitored by the substation terminals connected to the communication channel where the abnormality occurred through the different substation terminals that received the command. The monitoring and control system includes the main central line system (209) installed in the sales office and the central backup system (208). The monitoring and control system also includes the function of linking the terminals of different substations. In the event of a malfunction in the communication channel intended for each substation terminal, the substation terminal will be connected to the central main system (or backup central system). Commands will then be issued to different substation terminals to establish interconnections and communicate with the central main system (or backup central system) in place of the substation terminals. With this structure, the central main system monitors and controls the switches that are being monitored by the substation terminals connected to the faulty communication channel. This control and monitoring process extends to the interconnection function of the various substation terminal devices. In the event of a malfunction in the communication channel intended for each substation terminal device, the substation terminal will be connected to the central main system (or backup central system) and commands will be issued to the various substation terminal devices to establish interconnections and communicate with the central main system (or backup central system), replacing the substation terminal devices. The various substations receive commands, allowing the main central system to monitor and control the operation of switches, which are then checked by the terminal devices of the substations connected to the communication channel, where abnormalities may occur.

Claims (10)

1. Monitoring and Control System, which includes the central main line system that monitors and controls the first and second substations; the first and second distribution lines connected to the first and second substations, respectively; the first and second switches in the first and second distribution lines, respectively; the terminals of the first and second substations, respectively, that monitor and control the first and second switches, respectively; the first communication channel, which provides communication between the central main line system and the terminals of the first and second substations, respectively; the inter-substation communication channel, which provides communication between the terminals of the first and second substations; and the substation terminal link pathway, which provides communication between the terminal of the first substation and the central main line system. When the first communication channel is inoperable, communication occurs through the inter-substation communication channel, the terminal of the second substation, and the second communication channel, so that the central main line system monitors and controls the first switch. 2. Monitoring and control system pursuant to claim 1, whereby the terminal link of the substation shall be located outside the terminal of the second substation. 3. Monitoring and control system pursuant to claim 1, whereby the substation terminal linkage pathway shall be a component of the second substation terminal. 4. A monitoring and control system, pursuant to claim 1, whereby the terminals of the second substation shall incorporate fault processing pathways that store information for the first and second switches and respond to line faults in the first line when the first communication channel fails. 5. Monitoring and control system as per claim 1, which includes a second central main line system and communication switch devices connecting the first and second communication channels, and the first and second central main lines for the first and second communication channel switches as a second central main line system when the first central main line system fails. 6. Monitoring and Control System, which includes a central main line monitoring and controlling a number of substations, a number of distribution lines, each connected to a corresponding substation, a number of switches located on the corresponding distribution lines, a number of substation terminals, each terminal assigned to a specific substation and monitoring and controlling the corresponding switches for each substation, sequential inter-substation communication channels providing communication between each substation and two other substations, and substation terminal linking pathways provided for each substation terminal to provide communication between the first substation terminal and the central main line system. When the communication channel between the central main line system and the first substation terminal is not working, communication occurs through the second substation terminal connected to the first substation terminal, through the inter-substation communication channel connected to the first and second substation terminals, and through the communication channel between the central main line system and the second substation terminal. So that the central main line system will monitor and control the switches that are shared with the terminals of the first substation. 7. The monitoring and control system pursuant to claim paragraph 5, where each pathway connecting the substation terminals for each substation terminal shall be a component of each substation terminal. 8. A monitoring and control system pursuant to claim paragraph 5, where each substation terminal link is located outside the terminal of each substation. 9. A monitoring and control system pursuant to claim paragraph 6, whereby each substation terminal shall comprise a fault processing pathway that stores information on switches corresponding to those monitored by each substation terminal and information on switches monitored by substation thermoterminals connected to each substation terminal via the substation inter-station communication channel, and when the communication channel between the first central main line system and the first substation terminal connected to each substation terminal via the substation inter-station communication channel of the first substation terminal connected to each substation terminal fails. 10. The monitoring and control system under claim 6 includes a second central main line system and communication channel switching devices connecting the first and second communication channels, and the first and second central main line systems for switching the first and second communication channels to the second central main line system when the first central main line system is inoperable.
