[0045] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0046] The double - car operation method provided by the embodiment of the present invention adjusts the distance between the upper car and the lower car on the one hand, and calculates the corresponding docking position of the main car frame under the condition that the target value of the double - car distance is determined on the other hand, and correspondingly controls the lifting of the main car frame. It realizes the separate regulation of the main car frame and the auxiliary car frames (the upper car and the lower car), and the operation control logic is clear and efficient, which can improve the operation efficiency of the double - car elevator, and is especially suitable for the calibration of the double - car elevator during installation and maintenance.

[0047] As Figure 1 shown, the double - car operation method provided by the embodiment of the present invention includes the following steps: obtaining the target floor information and obtaining the target value of the double - car distance corresponding to the target floor information; adjusting the upper car and the lower car to lift relative to the main car frame respectively according to the target value of the double - car distance; determining the docking position of the main car frame corresponding to the target floor under the condition that the upper car and the lower car reach the leveling positions respectively; controlling the main car frame to lift to the docking position.

[0048] In the case of uneven floor height distribution, adjusting the lifting of the auxiliary car frames (the upper car and the lower car) relative to the main car frame according to the target value of the double - car distance corresponding to the target floor information can ensure that the actual value of the double - car distance is equal to the target value of the double - car distance. Furthermore, when the main car frame reaches the docking position, the upper car and the lower car reach the corresponding leveling positions respectively.

[0049] In an embodiment of the present invention, the method for operating a double-deck car further includes: when the main car frame ascends or descends to a docking position, detecting the height deviations of the upper car and the lower car relative to their corresponding landing positions respectively; if the height deviations exceed a first preset deviation range, correcting the target value of the double-car spacing according to the height deviations; adjusting the ascents and descents of the upper car and the lower car relative to the main car frame respectively according to the corrected target value of the double-car spacing; correcting the docking position of the main car frame corresponding to the target floor according to the corrected target value of the double-car spacing, and detecting the height deviations of the upper car and the lower car relative to their corresponding landing positions respectively when the main car frame ascends or descends to the corrected docking position, and so on in a cycle until the height deviations meet the first preset deviation range. This method for operating a double-deck car can be executed in a cycle during installation or maintenance until the upper car and the lower car can reach their respective landing positions, or can be continuously executed during the long-term operation of the double-deck car elevator, so as to perform real-time verification to ensure that the upper car and the lower car can dock at the landing positions.

[0050] Further, adjusting the ascents and descents of the upper car and the lower car relative to the main car frame respectively according to the target value of the double-car spacing includes: calculating the lifting working duration of the main car frame when it ascends or descends to the docking position; calculating the minimum adjustment speeds of the upper car and the lower car for ascending and descending relative to the main car frame respectively within the lifting working duration to reach the target value of the double-car spacing; adjusting the ascents and descents of the upper car and the lower car relative to the main car frame respectively with a condition that the speed is greater than or equal to the minimum adjustment speed until the distance between the upper car and the lower car is equal to the target value of the double-car spacing. When the upper car and the lower car reach the target value of the double-car spacing at the minimum adjustment speed, the main car frame can reach the docking position corresponding to the target floor at the same time, and the running smoothness of the upper car and the lower car is the best.

[0051] Generally, when driving the upper car and the lower car to ascend and descend relative to the main car frame, linkage devices can be used to make the upper car and the lower car linked. When the upper car ascends relative to the main car frame, the lower car is driven to descend relative to the main car frame; when the upper car descends relative to the main car frame, the lower car is driven to ascend relative to the main car frame. In this way, the relative synchronous ascending and descending of the upper and lower cars can be realized, and then the actual value of the double-car spacing can be changed.

[0052] It should be noted that the corresponding method for operating a double-deck car can be calibrated according to the hoistway dimensions, the main car frame dimensions and the double-car spacing correlation, and the docking positions corresponding to each floor and the target values of the double-car spacing are recorded and calibrated, and the positions of the upper car and the lower car on the main car frame corresponding to the docking positions of each floor are recorded.

[0053] In an alternative embodiment, controlling the main car frame to ascend or descend to the docking position includes: calculating the spacing adjustment duration for the upper car and the lower car to ascend and descend relative to the main car frame respectively and reach the target value of the double-car spacing; calculating the lifting speed of the main car frame to ascend or descend to the docking position with a time greater than or equal to the spacing adjustment duration; controlling the main car frame to ascend or descend to the docking position at the lifting speed.

[0054] As a preferred embodiment, the lifting working duration can be made equal to the spacing adjustment duration. When reaching the docking position corresponding to the target floor information, the actual value of the double-car spacing just reaches the target value of the double-car spacing. This can ensure that when the main car frame is lifted to the docking position, both the upper car and the lower car have completed position adjustment, avoiding the situation that the upper car and the lower car still move up and down after the main car frame docks, which affects the smoothness of the car.

[0055] In an alternative embodiment, when there is a height deviation between the upper car and the lower car relative to the corresponding landing position, the height deviation can be stored in the memory. When the main car frame is driven to move up and down to the docking position again later, this height deviation can be used as a basis for correcting the target value of the double-car spacing. Through multiple cycles of control and correction, the height deviation between the upper car and the lower car relative to the corresponding landing position can be reduced.

[0056] In an alternative embodiment, the double-deck car operation method further includes: under the condition that the main car frame moves up and down to the docking position, respectively detecting the height deviations of the upper car and the lower car relative to the corresponding landing positions; if the height deviation corresponding to at least one of the upper car and the lower car exceeds the second preset deviation range, adjusting the corresponding upper car and lower car to move up and down until the height deviations of the upper car and the lower car conform to the second preset deviation range. Wherein, the second preset deviation range is greater than the first preset deviation range.

[0057] To avoid potential safety hazards caused by excessive height deviations between the upper car and the lower car relative to the corresponding landing positions, when the height deviation exceeds the second preset deviation range, the height deviation is reduced by adjusting the upper car and the lower car relative to the lifting of the main car frame, so that the upper car and the lower car can approach the corresponding landing positions.
