IP-based monitor camera system has been used to accomplish savings in labor in operating railway vehicles, such as passenger-carrying vehicles, and to confirm safety at multiple doors thereof. Provided are a monitoring system and a monitoring method which allow a train driver or a train crew to use a monitor installed in a leading or rearmost vehicle or the like for visually confirming motions of passengers in association with opening or closing of doors of the passenger-carrying vehicles at a time so as to ensure more safe and efficient operation of the passenger-carrying vehicle. Additionally, in the case where a train set of passenger-carrying vehicles is formed, when the areas of the trimming frames of images captured by monitor cameras are set for displaying the images on a monitor screen, the areas of the trimming frames of the monitor cameras are automatically read and set so that the trimming frames can be set for the train set of vehicles quickly, readily and reliably.

In a monitoring system, each individual camera device divides image data acquired by an image sensor unit into a plurality of areas, and detects video-image abnormality from an average luminance signal value in each area or from a change thereof. The camera device that has detected video abnormality transmits video-image abnormality detection information to a server. In the plurality of areas, it is possible to use different detection algorithms such as a first algorithm in which it is determined that an abnormality has occurred when there is no change in the average luminance value, a second algorithm in which it is determined that an abnormality has occurred when there is a change in the average luminance value, and a third algorithm for observing a change in the video captured while a change is made to an aperture, exposure time, or the like.


A wireless communication system includes a first wireless communication device and a second wireless communication device that wirelessly communicates with the first wireless communication device. One of the first and second wireless communication devices is disposed in a mobile object, and the other is fixed. The first wireless communication device includes a wireless transmission/reception unit that transmits data to the second wireless communication device and performs wireless transmission and reception in order to detect whether the mobile object is stopped. When, in a first mode for transmitting data to the second wireless communication device and determining whether the reception strength of a received signal is equal to or greater than a first value, the first wireless communication device detects that the reception strength is equal to or greater than the first value, the first wireless communication device stops the transmission of data to the second wireless communication device, exits the first mode, and transitions to a second mode for determining whether the mobile object is stopped. Upon detecting in the second mode that the mobile object is stopped, the first wireless communication device exits the second mode and transmits data to the second wireless communication device.

SISO decoding of a reception signal having a scrambled symbol arrangement is realized using a process having reduced complexity. Coordinates are generated for a reference point obtained by scrambling and mapping a symbol number not a symbol reference point position. This reference point simulates transmission-side scrambling and is generated for each symbol number by a first mapping unit. Because the binary expression of a corresponding original signal number is retained, a bit likelihood calculation unit can easily calculate a bit likelihood based on the distance between the reference point and a reception signal. The calculated bit likelihood is then deinterleaved and subjected to SISO error-correcting decoding. The thus obtained bit likelihood is then reinterleaved and used to calculate a symbol probability. Soft symbols are generated through the multiplication of all the calculated symbol probabilities by corresponding reference points output by a second mapping unit similar to the first mapping unit.
