摘要:
A failure history management system includes a radio identification tag that is placed on a device and stores device-identifying-information that identifies the device, a management computer for managing failure history data of the device, and a terminal unit configured to identify the device from the device-identifying information stored in the radio identification tag, to read failure history data of the device from the management computer, and to provide failure history data of the device to the management computer.
摘要:
A video signal transmission system for transmitting a plurality of color video signals and horizontal/vertical sync signals from a transmitter part to a receiver part through a plurality of signal transmission lines is disclosed. The transmitter part includes a modulating circuit for modulating the video signals by a modulation method based on a Manchester format and generating a plurality of modulated video signals including Non Return to Zero video data, a synchronizing circuit for performing Code Rule Violation processing of the horizontal/vertical sync signals to generate burst signal-like sync signals in synchronism with the modulated video signals, a mixing circuit for mixing the burst signal-like sync signals with some of the modulated video signals to generate a plurality of transmission signals numbering less than a sum of the numbers of the modulated video signals and the horizontal/vertical sync signals, and a transmission circuit for transmitting the transmission signals to the signal transmission lines.

摘要:
In a master-slave-type control system, a normal supervisory control station which is a master device, control terminal devices, and a stand-by supervisory control station which is a slave device for effecting an operation of the normal supervisory control station in place thereof are connected with a common transmission passage. The normal supervisory control station receives data from each control terminal device repeatedly sent on the transmission passage to the normal supervisory control station, collects the data from each control terminal device, and sends its internal data on the transmission passage to an imaginary station at the end of each period of data collection. The stand-by supervisory station intercepts the data of each control terminal device repeatedly send on the transmission passage to the normal supervisory control station, collects the data from each control terminal device, and intercepts the data sent from the normal supervisory control station on the transmission passage to the imaginary station at the end of each period of data collection, whereby switching from control by the normal supervisory control station to control by the stand-by supervisory control station is carried out.
