Abstract: Disclosed herein are a one-way data transmission apparatus, a one-way data reception apparatus, and a one-way data transmission/reception method using the apparatuses. The one-way data transmission/reception method uses a one-way data transmission apparatus and a one-way data reception apparatus, and includes receiving data from a high-security zone through a one-way path, generating tag information of the data, sending a message in which the tag information is added to the data to the one-way data reception apparatus, receiving the message from the one-way data transmission apparatus, checking the tag information of the message, and transmitting the data to a low-security zone.

CPC classification number: G01M99/005 , G05B13/0265
Abstract: In order to increase the accuracy of status or failure diagnosis of machine tools and reduce the time and costs required for data collection and algorithm development for diagnosis, sensors are mounted on specific elements of the machine tools and measurement data is collected while operating under the specific operating conditions during a time interval between one machining operation and another machining operation to perform status or failure diagnosis of the machine tools. According to the present invention, by using data collected while operating machine tools under the predefined specific conditions using a time interval between one machining operation and another machining operation, it is possible to more accurately perform diagnosis while allowing less noise to be mixed in the data and reducing the time required for data collection for the development of diagnostic algorithm.

Abstract: A method for detecting an abnormal traffic on a control system protocol, includes: checking whether session information exists in a management table; adding a new entry to the management table; checking whether a transaction ID in a table entry is the same as that of the received MODBUS request message; and checking whether data and length thereof of the received MODBUS request message are the same as those in the table entry. Further, the method includes detecting an abnormal traffic; and updating the table entry with packet information of the MODBUS request message.

IPC: G05D1/02
CPC classification number: G05D1/0208
Abstract: The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.
Abstract translation: 本发明涉及使用基于宽范围传感器的球面三角法来控制偏离锚固物的容器的装置和方法。 在该方法中，监测锚固在锚地中的船舶。 锚地被定义为一组，并且锚定的船只组被管理。 离开集装箱需要偏离锚地的船只被控制。 如果在经过预定时间段之后，被认定为与离开该组请求锚定的容器相同的容器的容器已经过去，则锚定请求容器被控制。
