<p>PURPOSE:To monitor icing on stringing and to send a proper command before an electric car enters an icing section, and to prevent trouble from occurring by providing a photographic machine which photographs the stringing and a means which judges the degree of incing on the stringing from a photographed image. CONSTITUTION:An industrial TV 5 is fitted to a car 6 and rails 7 are laid in parallel to the stringing 3 so as to photograph the shape of the stringing 3 accurately. Stringing 3 which is not evident about whether icing occurs or not is divided into N optional sections and the industrial TV 5 photographs the state of the stringing 3 in each section and sends an image to a CPU 8. Then, a means which judges whether icing on the stringing occurs or not, e.g. a CPU 8 is stored with the state of the stringing 3 when there is no icing and judges the icing from a change in the shape, e.g. thickness of the stringing 3 when ice 4 sticks on the stringing 3 to command an electric car to stop, reduce its speed, or carry on normal operation according to the degree of the icing.</p> |
