摘要： PROBLEM TO BE SOLVED: To provide a speed control device for an elevator to realize high- precise control of the elevation speed of a car. SOLUTION: A noise reducing means 1 reduces the generation of high frequency noise contained in a speed deviation between a car speed detected by a car speed detecting means and a car speed command. A target value follow-up control means 2 computes a car speed correction signal to cause a car speed to follow a car speed command based on the speed deviation by which the generation of high frequency noise is reduced. A speed converting means 3 converts a car speed target value, obtained by adding a car speed correction signal, a characteristic change compensation signal, and a car vibration suppression signal to a car speed command, into an electric motor speed target value. Namely, by using a car speed detecting value and by adding a correction signal for a characteristic change and vibration, follow control of the car speed target value is effected. This constitution controls a car speed to a car speed command with high precision.

SOLUTION: An image input device 4 instead of the usual VI meter is installed inside a tunnel for taking out the image data, and traffic volume measuring means 6, a visual environmental index judging means 10, and a fog generation judging means 12 are introduced. The traffic volume measuring means 6 measures the traffic volume from the area and pattern of the image data, and the traveling number of vehicles for each definite period is estimated by a traffic volume estimating means 7, and further the operation quantity planning value for the next period is taken out from the estimated value by a ventilation planning means 8. On the other hand, the visual environmental index judging means 10 judges the visual environment from the relationship between the image data and the driver's visual environmental, and takes out the feedback control output value by a ventilation feedback control means 11. A plan/feedback cooperation means 9 outputs a ventilator operation command value in cooperation with the traffic volume planning value and the control output value, while when fog generation is informed through the fog generation judging means, the ventilator operation command value for eliminating a fog is output.
