Abstract
The invention discloses an automatic control method of a freight elevator, which comprises the following steps: A) carrying out power-up initialization, reading data at the last power outage, automatically finding the position for leveling, leveling, then opening a door, and re-closing the door for detecting the performance of the door; B) opening and closing the door, and entering into the state for waiting for a command; C) waiting for the command till receiving the effect command; D) determining running direction by comparing data of a rotary encoder with the data of a well; E) entering into the running control state, and starting to run; and F) detecting a speed-reducing signal, pulling up and returning to the step C) for looping execution. The automatic control method of the freight elevator can greatly reduce the cost in comparison with the traditional PLC control through an industrial computer and an extended system; and the control method mainly uses the pulse counting of the rotary encoder to determine the floor height, and removes accumulated error by entering into a magnet vane for refreshing the data, and the control method has the advantages of simple and convenient control, safety and reliability. The automatic control method of the freight elevator is widely applied in the elevators.
