  • Publication number: 20220382235
    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.

  • Publication number: 20220329564
    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.

  • Patent number: 10761536
    Abstract: Vehicle systems that implement action planning for a vehicle have had difficulty in maintaining safety in the event of a failure in a recognition device since these systems generate trajectories and control the vehicle on the basis of outside-world information recognized by recognition devices. The present invention was conceived in light of the aforementioned situation and addresses the problem of maintaining safety even in the event of a failure in a recognition device of a vehicle system. This problem can be solved by an action planning device having a failure detection unit for detecting a failure in an outside-world recognition unit and a trajectory generation/determination unit for executing an action on the occurrence of a failure on the basis of outside-world information outputted by the outside-world recognition unit, wherein the trajectory generation/determination unit takes an action for coping with the failure on the basis of failure information from the failure detection unit.

  • Patent number: 8971318
    Abstract: A multistage relay communication system 100 includes a trunk network 1 and branch networks 2 (2a, 2b), each of which includes one or more communication apparatuses 4. The communication apparatus 4 can switch between a trunk mode to operate in the trunk network 1 and a branch mode to operate in the branch network 2. In the trunk network 1, the communication apparatus 4 carries out fixing of a communication path and redundancy of data based on a path table in order to achieve real-timeness and a data arrival rate. Meanwhile, in the branch network 2, when a communication failure occurs, the communication apparatus 4 autonomously searches for a communication path and constructs a path table, in order to at least secure a data arrival rate even if real-timeness is impaired within an allowable range.

  • Patent number: 8693481
    Abstract: A communication device reduces a processing time required at the time of mutually converting different wireless or wired communication protocol and improves a real-time property. The communication device includes two or more communication units which communicate with two or more external devices and a communication controller which processes communication data. The communication controller has table information that associates a communication path, a type of the communication unit, and conversion-info, and an input and output unit that inputs and outputs the table information. According to the added conversion-info, a conversion unit sequentially performs various conversion processes (protocol conversion, routing, communication quality evaluation, fragmentation/integration of communication interface, fragment/defragment process, frame multiplication/integration, and frequency setting).

  • Patent number: 8671300
    Abstract: A processing unit is connected to another processing unit through a system bus composed of serial signal communication line and synchronization signal communication line to be able to communicate therewith. When an operation unit detects abnormal state in the processing unit, the operation unit supplies notification of detection of the abnormal state to synchronization unit. The synchronization unit transmits the received detection notification of abnormal state to the other processing unit through the synchronization signal communication line. Conversion unit receives parallel communication data from the operation unit through important signal line instead of general signal line and converts the received parallel signal into serial signal to be transmitted to the other processing unit through the serial signal communication line, thereby soundness among processing units connected to the system bus is ensured when the system bus is configured to attain serial communication.

  • Patent number: 8564440
    Abstract: When an RFID is attached to an object to assist testing operations, the following problems are encountered; (1) the RFID of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed, (2) the incorporation of the reader function in a terminal block increases the cost, and (3) the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort. The operations are aided by using an RFID reader and a terminal having the function for accessing a database of circuit information, RFID information, and test procedure information.
