Problems solved by technology

This is equivalent to that the door operator has 5 position sensing intervals; however, there is a disadvantage in the operation of this position sensing area. When the elevator is just powered on, the door operator only knows 5 position intervals: 1. The judgment interval when it is fully open; 2. 1. Judgment interval of closing position; 3. Judgment interval of door opening deceleration; 4. Judgment interval of door closing deceleration; Judging the current operating position of the door, so the optimal and perfect curve operation control cannot be carried out, and there are potential safety hazards in operation

Embodiment 1

[0042] Taking the middle split door with car door type 900 as an example, the door opening and closing time T is set to 2s. Lateral distance L between the first ultrasonic sensor and the second ultrasonic sensor 1 100mm; sensing distance by sensor: the current distance L between the first ultrasonic sensor and the right side of the door operator 3 is 200mm; the current distance L between the second ultrasonic sensor and the left side of the door operator 4 is 600mm, and the calculated width of the car door is 450mm; Substitute the above data into the maximum operating speed formula:

[0043] (1) Vmax = (100mm+200mm+600mm) / 2 / 2s =450mm / 2s= 225mm / s;

[0044] (2) V= 4×(225mm / s) / (2s) 2 ×t 2 =225mm / s 3 ×t 2 ;

[0045] When the highest speed of the door is running at 1s, it is brought into t, V= 4×(225mm / s) / (2s) 2 ×t 2 =225mm / s 3 ×t 2 =225mm / s 3 ×(1s) 2 = 225mm / s.

[0046] The running curve corresponding to each real-time running time can be calculated through the ...

Abstract

The invention relates to an elevator door motor controller capable of automatically recognizing the door width and a door position. The elevator door motor controller comprises a motor driving unit, a user interface unit, an ultrasonic ranging system, a ranging processing unit, a CPU and a storage device which are arranged in a box body. The ultrasonic ranging system comprises a first ultrasonic sensor, a second ultrasonic sensor and a third ultrasonic sensor which are connected with the ranging processing unit, and the ranging processing unit, the motor driving unit, the user interface unit and the storage device are connected with the CPU. The elevator door motor controller is more convenient to install and debug, and higher safety and higher reliability are achieved on the operation of an elevator.

Description

technical field [0001] The invention relates to an elevator door machine control device, in particular to an elevator door machine controller which can automatically identify door width and door position. Background technique [0002] At present, elevators have become an indispensable means of commercial and residential transportation in daily life. With the rapid development and progress of society, more and more elevator manufacturers consider the comfort and high performance of elevators. [0003] For example, the patent disclosed at present, CN204162258.U, its patent claims describe and understand as: utilize 4 steady-state switches installed on the elevator door head plate as the running zone sensor of door position, pass the state of 4 steady-state switches in operation To switch relative running speed. This is equivalent to that the door operator has 5 position sensing intervals; however, there is a disadvantage in the operation of this position sensing area. When th...
