Abstract: Conventional security measures are generally intended for an IT system, and it has been difficult to satisfy a real-time property and availability requested to a control system. Furthermore, since a time-division type time slot communication method is not taken into consideration, such time slot communication has problems in efficient utilization of computer resources and decrease in availability. In order to solve the above-described problems, the present invention specifies a time slot from characteristics of a communication packet received by a reception unit 133 by using a time slot characteristic storage unit 130, and selects, in accordance with the specified time slot, an inspection pattern stored in an inspection pattern storage unit 136 by using an inspection pattern selection unit 131.

Abstract: In the conventional distributed control system, since each control device updates the data area at a timing when a control packet is received, in a case where there is a difference in communication delay between the control devices or in a case where the communication delay includes jitter, it is difficult to match the contents of data in all the control devices in a case of focusing on a certain moment during system operation. Therefore, depending on the start timing of a control application, the control application operates on the basis of different data between the control devices, thus limiting control performance improvement. Accordingly, time slots on the network are allocated according to the result of a calculation unit, and a cyclic memory synchronization update unit synchronizes the timing of reflecting data in the input/output and the cyclic memory and the timing of using data of a cyclic memory.

Abstract: A partial discharge detection apparatus for detecting partial discharge in a power cable and recognizing an insulation deterioration state of the power cable. A low-speed AD converter converts an analog signal of an AC waveform flowing through a power cable into a digital signal. A high-speed AD converter converts an analog signal of a partial discharge current into a digital signal. The partial discharge is detected based on the maximum value or the sum of a current value obtained from the digital signal of the partial discharge current obtained by the conversion of the high-speed AD converter, for each phase of the AC waveform, which is obtained from the digital signal of the AC waveform flowing in the power cable. The digital signal is obtained by the conversion of the low-speed AD converter.

Abstract: Even when a priority frame and a non-priority frame are provided as communication frames, real-time performance and security of communications are both provided. A rule verification portion 7 tests a communication frame in accordance with a test rule and determines whether the communication frame is an invalid frame. Verification status hold portions 4 and 5 hold status information that indicates a status of the test by the rule verification portion 7. An interception control portion 8 controls interception of the communication frame based on a determination result of the rule verification portion 7. When an I/F portion 1 receives a fragment of a non-priority frame, the rule verification portion 7 tests the fragment to test the non-priority frame, when ending the test on the fragment, interrupts the test on the non-priority frame, and when the I/F portion 1 receives a next fragment, resumes the test on the non-priority frame based on status information.
