Description

  The present invention relates to an updating method and an updating system for a plant monitoring system used in a nuclear power plant or the like.

When updating a plant monitoring system used in a nuclear power plant or the like, conventionally, the plant monitoring system including the casing of the plant monitoring system has been updated in a lump (Patent Document 1).
A method for updating such a conventional plant monitoring system will be described with reference to FIG.

  FIG. 5 shows a configuration before and after updating the plant monitoring system. The plant monitoring system includes a plurality of existing PIO boards (process signal input / output boards) 18 for inputting / outputting process data and an existing computer 15 for performing alarm processing / display processing. The existing PIO board 18 houses the existing PIO device 10 and the terminal block 18b configured by a controller, a relay, and the like, and the existing PIO device 10 and the terminal block 18b are connected by an existing wiring 18c. The terminal block 18 b of the existing PIO board 18 is connected to the field device 12 such as a pump via the field device cable 13, and the existing PIO device 10 is connected to the existing computer 15 via the existing network 16.

  When updating the plant monitoring system, the existing network 16 cable connected to the existing server 15a and the existing client 15b of the existing computer 15 is disconnected, and the existing computer 15 is removed. At the same time, in conjunction with the removal of the existing computer 15, the on-site equipment cable 13 connecting the existing PIO board 18 and the on-site equipment 12 and the existing network 16 cable connected to the existing computer 15 are removed, and the existing PIO board 18 is removed. Remove.

  Therefore, plant monitoring functions such as alarm processing and display processing are lost from the time when the existing network 16 cable connected to the existing server 15a and the existing client 15b of the existing computer 15 is disconnected.

  When the removal of the existing computer 15 is completed, the new computer 1 is carried in, and the new server 1 a and the new client 1 b are connected to the new network 17. After the existing PIO device 10 of the existing PIO board 18 is removed, the new PIO device 5 and the new terminal block 19b of the new PIO board 19 are loaded, and the new PIO device 5 and the new terminal block 19b are connected by the new wiring 19c. Then, the inter-site equipment cable 13 connecting the on-site equipment 12 is connected to the new PIO board 19, and the new installed work 17 is connected to the new PIO device 5. At this point, since the new computer 1 has not been tested, the plant monitoring function remains lost.

  The plant monitoring function confirmation test such as the alarm processing / display processing function of the new computer 1 is conducted by a tester simulating a network reception signal from the new PIO board 19 and transmitted to the new server and new client of the new computer 1 via the new network 17. A confirmation test is being conducted. In addition, the connection confirmation test between the new PIO board 19 and the field device 12 is performed by a tester simulating an input signal from the field device 12 and another tester confirming the input signal on the new PIO board 19. ing. When these tests are completed, the process data input of the new PIO board 19 is started and the update is completed.

  Thus, along with the plant monitoring system update, the existing network 16 cable connected to the existing server 15a and the existing client 15b of the existing computer 15 and the existing PIO board 18 were disconnected from the on-site equipment cable 13 and then carried in. The monitoring display process data input function is stopped and the plant monitoring function is lost for a long time until the test of the new computer 1 and the new PIO board 19 is completed.

  In addition, the test of the new computer is performed by removing the network cable of the existing computer and the cable between field devices, removing the existing computer, removing the existing PIO, carrying in the new computer, carrying in the new PIO board, and between the field devices. This must be done after connecting the cable and network cable, and it takes a long time from the start of the plant monitoring system update to the test of the new computer.

  Furthermore, the servers and clients that are computers of the plant monitoring system must always operate normally in accordance with the plant operation until the batch update is performed. Therefore, computers that can perform long-term maintenance and repair must be selected. Don't be. The maintenance period of the computer applied to the plant monitoring system is required to be about 15 years based on the update period of the PIO device.

  On the other hand, in recent years, it has become difficult to maintain and maintain computer parts for a long period of time, and a method for updating only a client computer or a server computer without updating a PIO device has been proposed in a method for updating a plant monitoring system. This update method will be described with reference to FIG.

  When updating the plant monitoring system, the cable is removed from the existing network 16 connected to the existing server 15a and the existing client 15b of the existing computer 15, and the existing computer 15 is removed. The plant monitoring function is lost when the existing computer 15 is disconnected from the existing network 16. When the removal of the existing computer 15 is completed, the gateway computer 50 and the new computer 1 are carried in, and the new server 1a and the new client 1b are connected to the new network 17.

  The gateway computer 50 is connected to the existing network 16 to which the existing PIO board 18 is connected and the new network 17 to which the new computer 1 is connected. At this time, since the gateway computer 50 and the new computer 1 are not tested, the plant monitoring function remains lost.

In the confirmation test of the plant monitoring function of the new computer 1, a tester inputs a simulated network reception signal from the existing PIO board 18, and a new server and new client transmission confirmation test of the new computer 1 via the gateway computer 50 and the new network 17 Has been implemented. The gateway computer 50 receives process data from the existing PIO board 18 by the existing PIO communication means 50a, and the received process data is converted by the existing PIO conversion means 50b by the data format and data to be processed by the new computer. The data is transmitted from the computer communication means 50 c to the new server and new client of the new computer 1 via the new network 17.
When these tests are completed, the process data of the existing PIO board 18 is started to be input to the new computer 1 and the update is completed.

  As described above, the test of the new computer 1 and the gateway computer 50 carried in from the time when the cable is disconnected from the existing network 16 connected to the existing server 15a and the existing client 15b of the existing computer 15 with the plant monitoring system update. For a long time until completion, the monitoring display process data input function is stopped and the plant monitoring function is also lost. The test of the new computer must be performed after removing the network cable and external cable of the existing computer, removing the existing computer, bringing in the new computer and gateway computer, and connecting the network cable. It takes a long time to test a new computer.

  In order to realize the display function of the new computer 1 and the monitoring function performance before the update such as data recording, the process data transmission processing that the existing PIO board 18 transmits to the gateway computer 50 and the process data converted by the gateway computer 50 are newly installed. The series of processing time until transmission to 1 needs to realize a period equal to or longer than the process data reception period of the existing computer 15 before the update. For this reason, it is necessary to use, as the gateway computer 50, a computer that can change the setting for shortening the process data transmission cycle of the existing PIO board 18 and can receive process data with a short cycle.
