Problems solved by technology

In a single-shaft multi-car elevator system, since there are multiple cars running on the same vertical plane and can also run horizontally, wire rope traction cannot be used as the way to provide running power, so the steel wire rope stiffness is used to determine the position of the car method is not feasible

Embodiment

[0032] Example: such as figure 1 As shown, a kind of give way type multi-car circulation elevator system comprises a vertical ascending hoistway 16 and a vertical descending hoistway 17 vertically side by side, the middle of the two is separated by a vertical hoistway partition wall 6, but the bottom and The top floor is interconnected; on the outside of the vertical ascending shaft 16 and the vertical descending shaft 17, each floor is respectively provided with avoiding horizontal shafts 18 perpendicular to each other, and the avoiding horizontal shafts 18 are separated by the avoiding horizontal shaft partition wall 5; Several cars 14 are arranged in the hoistway 16 of ascending, the vertical descent shaft 17 and the horizontal shaft 18 of avoidance;

[0033] On the vertical rail backboard 1 of the vertical ascending shaft 16 and the vertical descending shaft 17, a circular rail turning disc 3 is set; the orbit turning disc 3 corresponds to the vertical ascending shaft 16 a...

Abstract

The invention provides a car position determining method for a multi-car elevator system comprising a vertical hoistway car position determining device and a horizontal hoistway car position determining device. The car position determining method comprises the following steps: the vertical hoistway car position determining device and the horizontal hoistway car position determining device simultaneously work to measure data, the vertical hoistway car position determining device transmits the reflection time to a data processor, the horizontal hoistway car position determining device transmitsthe pressed position to the data processor, and the data processor determines real-time positions of all the cars in the hoistway. The beneficial effects of the invention are that the vertical hoistway car position determining device works simultaneously with the horizontal hoistway car position determining device, the positions of all the cars can be determined in real time, the accuracy and real-time performance of the plurality of car positions simultaneously determined are improved, and an elevator dispatch system is provided with more accurate real-time positions of the cars.

Description

technical field [0001] The invention belongs to the field of elevator dispatching control methods, in particular to a method for determining car positions in a multi-car elevator system. Background technique [0002] With the development of the city, the building is getting taller and taller, but the time we wait for the elevator is getting longer and longer. The configuration of the elevator is always a major weakness of the high-rise building. Especially during peak usage periods such as commuting and lunch breaks, it is impossible to go up to more than ten floors for half an hour. For example: large office buildings, large hospitals. For decades, building engineers have been able to alleviate this problem only by building multiple shafts. But the construction of multiple wells will increase the construction cost and occupy a lot of space, so multiple buildings do not allow the appearance of elevator systems with multiple wells. [0003] The appearance of a kind of give...
