Occurrence of overcharging and over discharging of batteries mounted on vehicles that travel on tracks in a wireless transit system is prevented by estimating a state of charge (SOC) of the batteries with accuracy. An equivalent circuit of the battery is composed of three circuit elements connected in series, including (i) a first component resistance R1 (ii) a component circuit which includes a capacitance C and a second component resistance R2 connected in parallel and (iii) an open circuit voltage of the battery. The open circuit voltage of the equivalent circuit is calculated using R1 calculated from measurements of current and voltage of the battery, as well as values k=R2/R1 and &#x3c4;=C&#xd7;R2. The SOC if the battery is calculated from the open circuit voltage.

A monitoring apparatus is provided which can ensure the prevention of a paper break even in a poor installation environment. A light source () illuminates light () on a lateral edge () of wet paper () and a camera () captures light () reflected therefrom. The camera () is a micro camera and completely covered by a camera box (). The camera box () has an observation window () which is made of a transparent member, at the lens side () of the camera (). The outer surface of the observation window () is coated and an air curtain () that flows from above to below prevents staining caused by mist. The air curtain () is formed in such a manner that air that is continuously supplied inside a cover () flows along the outer surface of the observation window () from an opening portion (). A color image obtained by the camera () is subjected to image processing in an image processing device () and the resulting image is projected on a monitor TV (), so that variations of the release point () can be monitored. This allows for forecasting of a machine abnormality leading to a paper break.

Monitoring device

The detecting system has a first rotating body with a first mark, a second rotating body with a second mark, a mark sensor for detecting the first mark, a first camera for imaging the second mark when the mark sensor detects the first mark, and a display section for displaying the second mark imaged by the first camera. The rotational phase difference is detected from a position of an image of the second mark displayed on the display section and is thus detected very accurately with a simple construction comprising the mark sensor, the first camera, and the display section.

Method and apparatus for detecting angular phase difference

There is provided a monitoring apparatus for preventing paper breakage. For this monitoring apparatus, a light source is disposed on the upper side of a wet paper and a light emitting face thereof faces downward. An operation-side camera a and a drive-side camera b are disposed on the side opposite to the light source with respect to the wet paper and a lens face thereof faces upward. Light a of the light source passes through the wet paper after being reflected from a mirror and is caught by the cameras a and b. Thus, the cameras a and b photograph a silhouette (image) of the light a of the light source which has passed through the wet paper This image is sent to an image processing unit where the image is processed. The coordinates of a boundary line such that the wet paper separates from a center roll is detected from the images photographed from two directions. This coordinate value is sent to a computer The computer converts the value into a movement amount in each sampling cycle to determine the change amount and frequency of a separation point and the whole shape of separation lines a and b. Thereby, a machine trouble resulting in paper breakage can be predicted.
