TH22366A - Elevator control device - Google Patents

Abstract

One type of elevator control device that can reduce the risk of passengers getting stuck in the elevator cabin. And can prevent damage to the birthing equipment that is dangerous for passengers The equipment included Hazard protection circuit (1) for detecting an elevator flip-flop fault (35) for storing the operation of the hazard protection circuit (1) Detection circuit where the door can be opened (2) for detecting Hold that A position where the cab stops is where the door of the passenger compartment can be opened, a control circuit (3A) for transmitting assistance operations on the basis of various flip-flop outputs. (35) and the area detection circuit that can open the door (2) After the operation of the hazard protection circuit (1), the signal for canceling the memory of the flip-flop 35 will be sent continuously. After the first predefined period until the second predefined period has passed. After the second predetermined period The elevator cabin will be inhibited when starting movement.

Claims (6)

1.One type of elevator control device for controlling a driver for an elevator's cabin consisting of Hazard protection circuit for detecting elevator malfunctions Anomaly storage path for storing various parameters to detect anomalies. A door open area detection circuit for detecting the position where the passenger compartment is stopped is the position within the area where the cab doors can be opened and the control path for controlling the device on the basis of the signal output. All of the methods of collecting such anomalies and sensing circuits in which the doors can be opened. Until when the way to keep such anomalies Stores various parameters, detect malfunctions Such a control path stops the passenger compartment inside the area where the door can be opened. If the cabin is moving Will open the door to allow passengers to come out of the cabin And thereafter inhibits the restart of the passenger compartment and where the aforementioned control route will open the door for the passenger to exit the passenger compartment if such cabin stops within an area where the door can be opened. And after that will inhibit the restart of the passenger cabin And where such control methods are continually terminated over a pre-determined period of time together Parameters detect anomalies stored in the said fault path if the passenger compartment is stopped within an area where the door cannot be opened. Such a control method will result in a rescue operation. When the fault detection parameters are canceled And such a control path inhibits the restart of the passenger compartment when the fault detection parameters have not been canceled. 2. One type of elevator control device according to claim 1, where after the fault is detected by the safety protection circuit, it is collected by such anomalies collection method. But before the first predetermined period Such a control path stops the passenger compartment within an area where the door can be opened. If the cabin is moving Will open the door for passengers to come out of the cabin And after that will inhibit the restart of the passenger cabin Where and such means of control will open the door for passengers to come out of the cabin If the passenger compartment stops within an area where the doors can be opened and afterwards, the passenger's restart is inhibited. And such a control path generates a cancel signal after the first predetermined period has elapsed. Go to the route to collect the fault if the passenger compartment stops within an area where the door cannot be opened. Such a control path will result in a rescue operation when the memory of the retention route is canceled. Such rescue operations include Causing the cabin to move at a slower than normal speed to an area where the doors can be opened Which is as close to the ground floor as possible And then open the door for passengers to come out of the cabin Such control methods work continuously. Until the second predetermined period has elapsed, the transmissions abort if the memory of the anomaly retention path has not been canceled even though the cancellation signal was initiated. Such a control path will result in the intervention operation following the termination of the retention route. And the aforementioned control method will inhibit the restart of the said cabin If such cancellation is not effective through the second predetermined period 3. One type of elevator control device in accordance with claim 2, which the aforementioned control method consists of a method to collect the anomaly. The circuit detects the area that can open such doors. And a further control circuit to the aforementioned driving device for the passenger compartment.The control circuit consists of a CPU, a memory that stores programs as The CPU performs the function described above. And a timer for timing as specified in the first and second periods as 4. A type of elevator control device according to claim 3, where the fault collector route consists of a flip-flop circuit arranged in a control circuit. 5.The method of operating the cabin depends on the detection of anomaly. Which consists of Storing the fault parameters in a memory device Elevator cabin position detection to determine whether the passenger compartment is within the area where the door can be opened or not. The measure of the number of times the cabin stops for the passenger compartment is set within the area where the doors can be opened. Cancellation signal is given to the memory device when the number of cabin stops is greater than the first predetermined period. And less than the second predetermined period Driving in the elevator cab at low speeds responds to the output from the memory device and stops the passenger compartment to enter areas where the doors can be opened. 6. The method as requested in claim 5 continues to include prohibiting the cabin from restarting when the number of times the cabin stops more than the second predetermined period.
