Description

  Embodiments of the present invention relate to a plant information reporting system that transmits a plurality of types of plant data for confirmation of normal operation of a nuclear power plant and judgment of an emergency situation.

  There is a plant information reporting system that constantly transmits major plant data to the outside for confirmation of the normal operation status of nuclear power plants and judgment of emergency situations. In the plant information reporting system, it is necessary to diversify the signal transmission path due to the importance of the response in an emergency. It is necessary to input and transmit plant data signals.

  Even when a device different from the device provided in the conventional signal transmission path is separately provided, the work for checking the soundness of the facility is performed at the time of periodic inspection. Therefore, even if the value of the plant data becomes different from the true value during the operation of the plant, there is a possibility that this abnormal state cannot be found.

  Also, the possibility of disconnection of the cable of the signal transmission path due to the effects of disasters such as earthquakes, the transmission circuit on the transmission side of the detected major plant data, and the output information output from this transmission circuit are received. A malfunction may occur due to an impact load applied to the input / output circuit. In such a case, erroneous plant information may be transmitted in an emergency, which may lead to erroneous determination. Therefore, provision of information including the soundness of major plant data is required.

  For example, as described in Patent Document 1, a configuration as shown in FIG. 12 is adopted as a configuration of a conventional plant information reporting system. As shown in FIG. 12, detection signals from various sensors installed in the plant 100, that is, various plant data are output from the transmission circuit 101 to the process input device 201 disposed in the central operation chamber. Then, the plant data collection unit 202 of the communication side system 200 collects various plant data input from the process input device 201 and stores it in the input database 203.

  The various types of plant data are displayed in the central operation room, transmitted to the outside from the information transmission unit 204, and received by the periodic data reception unit 401 installed in an emergency countermeasure room or the like outside the central operation room. Various plant data received by the periodic data receiving unit 401 is displayed on the data display unit 404 of the receiving system 400 including the periodic data receiving unit 401.

  In this way, in the central operation room, it is possible to determine the occurrence of plant alarm conditions and abnormal events by grasping various plant data, as well as for emergency response rooms that supervise multiple plants. Each plant data can be reported from the central control room. Then, plant information can be shared between a central operation room inside the plant and an external emergency response room, and the plant state can be grasped and monitored simultaneously.

JP 2011-145206 A

  Even if another plant information reporting system is configured in parallel with the above-described conventional plant information reporting system, the various plant data displayed are transmitted through the various plant information reporting systems with priorities. The data is displayed on a display device provided in the emergency response room or the like. That is, of the two plant information reporting systems, various plant data transmitted by one of the plant information reporting systems to which priority is given are displayed.

  And the soundness confirmation in these plant data input paths will be carried out in periodic inspections performed while the plant is stopped, and it will be found even if the process value becomes different from the true value during plant operation. It is unlikely to be done. In addition, there is a possibility that the cable may be disconnected in an emergency such as the occurrence of an earthquake, and if an incorrect plant state is transmitted in an emergency, this may lead to an erroneous determination, and the emergency response measures may be incorrect. was there.

  An object of this invention is to provide the plant information notification system which can judge the soundness of the plant data transmitted by a plant information notification system also at the time of normal time, an accident, and an emergency.

From the transmission circuit 101, the detected various plant data are sequentially output by serial number processing described later.

(First communication side system)
Various plant data output from the transmission circuit 101 is input to the first process input device 201 and the second process input device 301. In the above description, the case where one plant data is detected by one sensor has been described. However, one plant data can also be detected individually using two sensors. In this case, the plant data detected by one sensor can be output to the first process input device 201, and the plant data detected by the other sensor can be output to the second process input device 301.

  Various plant data input to the first process input device 201 are input to the first plant data collection unit 202 and stored in the first input database 203. In the above description, the case where the respective plant data detected by the various sensors is output from the transmission circuit 101 has been described. However, the first process is performed via the transmission circuit 101 corresponding to the plant data from the various sensors.

A data group of various plant data stored in the first input database 203 is output from the first information transmission unit 204 to the first periodic data reception unit 401 of the reception-side system 400.

  The transmission circuit 101 and the first process input device 201 are connected by a first transmission path 211, and the first process input device 201 and the first communication side system 200 are connected by a second transmission path 212. The first communication side system 200 and the first periodic data receiving unit 401 are connected by a third transmission line 213. The first signal transmission path 210 is configured by the first transmission path 211, the second transmission path 212, the transmission path in the first communication side system 200, and the third transmission path 213.

(Second communication system)
Various plant data input to the second process input device 301 is input to the second plant data collection unit 302 and stored in the second input database 303. In the second input database 303, various plant data collected in the data group in the second plant data collection unit 302 is stored.

That is, the data A to data E can specify the plant data in which part of the plant is detected by the input point number 701. Similarly, the data A ′ to data E ′ can specify the plant data detected in which part of the plant by the input point number 702.
The data comparison unit 501 and the comparison database 502 constitute a first comparison determination unit.

  The determination reference value 703 is defined for all plant data to be displayed on the data display unit 404, and the same type of plant data (data A and data A ′, data B and data B ′, data C and data C ′, data D and data D ′, and data E and data E ′) are defined. For example, between data A and data A ′, an allowable range for determining whether the allowable difference is within what percentage can be determined as the same type of plant data is defined. The determination reference value 703 can be set in advance.

  The contact input indicates a signal indicating whether or not a signal is received between the signal circuit 101 and the first process input device 201 and the second process input device 301. It is confirmed by the sections 605 (see FIG. 9), 606 (see FIG. 10), and 609 (see FIG. 11). The analog input indicates a detection signal detected by various sensors provided in the plant 100.

As a comparison result in the data comparison unit 501, an input point number and the following states (state 1 to state 4) are displayed on the data display unit 404. The meanings of states 1 to 4 can be defined as follows. That is,
As the meaning of the state 1, the plant data of the same input point number is the same in the first communication side system 200 and the second communication side system 300, and this plant data is reliable.
As the meaning of the state 2, the plant data of the same input point number is inconsistent between the first communication side system 200 and the second communication side system 300, and therefore this plant data is not reliable.
