Control device for hydraulic elevator
专利汇可以提供Control device for hydraulic elevator专利检索，专利查询，专利分析的服务。并且PURPOSE: To shorten the elevator cage operating time from its start-up to its stop at a floor by correcting the door opening time on the basis of the low speed running time, changeable according to the oil temperature, of an elevator cage until its stop at the floor and controlling the actual door opening/closing of the elevator cage by this corrected door opening time.
CONSTITUTION: An elevator deceleration command signal inputted from an operating circuit 2 and the output from a speed detecting circuit 9 are provided. Whether or not an elevator cage 4 is stopped at a floor is then judged according to the elevator deceleration command signal from the operating circuit 2. If the judgment is negative, this state is maintained, but if it is affirmative, counting is started from zero on the basis of the output from the speed detecting circuit 9 as well as the low speed running time T2 is obtained from the count value until the stop of the elevator. The deviation is obtained from the low speed running time T2 and the most appropriate low speed running time T1, the door opening extended time is obtained by multiplying this deviation by a constant, and the opening of a door 7 is controlled by the corrected door opening time obtained by adding this door opening extended time to the set door opening time.
