The car scheduling method based on the above-mentioned track cutting device is: when it is necessary to assign the i car on the m-th main rail 1 to the m+x-th main rail 1, switch the switching device on each main rail 1 2. Connect the m-th main rail 1, the switching device 2 on the m-th main rail 1, the switching device 2 on the m+1-th main rail 1, ..., the switching device on the m+x-th main rail 1 2 and the m+xth main rail 1 are sequentially connected and conducted, so that the i car on the mth main rail 1 passes through the m, m+1, ..., m+x main rail 1 in sequence After the switching device 2, enter the m+xth main track 1, where i≥1, x≥1.

Generally, two modes of dispatching need to be carried out through the track cutting device: one-point-multiple and many-in-one. More than one point means that multiple cars 4 on one main rail 1 are dispatched and distributed to other k main rails 1 through the track cutting device. This situation is suitable for the up peak. All-in-one refers to scheduling and distributing multiple cars 4 on multiple main rails 1 to other main rails 1 through the track cutting device, which is suitable for down peaks. Scheduling is done below the base layer. The following specific analysis:

1) more than one point

Assign the a car on the m main rail 1 to the m+k1, ..., m+kn main rail 1, and the assigned car 4 on each main rail 1 is one or more . Among them, where n≥2, k1<kn, k1, ..., kn are continuous or discontinuous natural numbers, that is, the n main rails 1 of the car 4 to be allocated can be sequentially arranged continuously or discontinuously arranged . The scheduling method includes the steps of:

Step S1: switch the switching device 2 on each main rail 1, and switch the m-th main rail 1 and the switching device 2 on the m-th main rail 1 to the switching device 2 and the switching device 2 on the m+kn-th main rail 1 The m+kn main rails 1 are sequentially connected and conducted, so that the nth batch of cars on the mth main rail 1 pass through the switching devices 2 on the m, ..., m+kn main rails 1 in sequence, and then enter the first m+kn main track 1. The nth batch of cars includes one car or a plurality of cars.

In step S1, the upper track of the m-th main rail 1 is connected to the transition track 3 on the right side of the m-th main rail 1 through the switching device 2, and the transition track 3 on the right side of the m-th main rail 1 is the m-th main rail 1. Transition track 3 between track 1 and the m+1th main track 1. The lower track of the m+kn main rail 1 is connected to the transition track 3 on the left side of the m+kn main rail 1 through the switching device 2, and the transition track 3 on the left side of the m+kn main rail 1 is the transition track 3 on the left side of the m+kn main rail 1 The transition track 3 between the m+kn main track 1 and the m+kn-1 main track 1.

In this step, the nth batch of cars on the mth main rail 1 arrive at the lower track of the m+knth main rail 1 .

It should be noted that in this embodiment, the reason why the upper rails of two adjacent main rails 1 are not directly connected to each other is to prevent the car 4 from overturning relative to the suspension device. Car 4 need guarantee to be in vertical state all the time during operation, so that the passenger in the car can be in vertical state. The guide device on the suspension device generally includes two groups, is respectively upper guide device and lower guide device, and guide device, car 4 are all hinged on the suspension device. When running along the main rail 1, the upper guide is positioned above the lower guide. If the upper rails of two adjacent main rails 1 are connected to each other through the switching device 2, for example, for the m main rail 1 and the m+1 main rail 1, the upper rail of the m main rail 1 and the m After the upper track of +1 main rail 1 is turned on, when the car 4 is on the mth main rail 1, the upper guide device is located above the lower guide device. Since the guide device runs along the main rail 1, when the car 4 After the upper track of the m-th main rail 1 passes through the switching device 2 and directly enters the upper track of the m+1-th main rail 1, the lower guide device will be located above the upper guide device. Since the car 4 and the suspension device are hinged, the car 4 can keep vertical, can cause car 4 to overturn with respect to suspension device this moment, can cause the passenger in the car 4 to overturn now, obviously this does not allow to take place. Simultaneously, turning over will affect the relative arrangement of each component on the suspension device and the car 4, and interference may occur between the car 4 and each component of the suspension device, which will affect the system operation.

Step S2: switch the switching device 2 on the m+kn main track 1 to switch on two adjacent sections of the m+kn main track 1 .

In this step, after the upper track and the lower track of the m+kn main rail 1 are connected through the switching device 2, the nth batch of cars on the lower track can pass through the switching device 2 and enter the upper track to pick up passengers.

Step S3: switch the switching device 2 on the m+kn-1 main rail 1 to make the m-th main rail 1, and switch the switching device 2 on the m-th main rail 1 to the m+kn-1 main rail The switching device 2 on 1 and the m+kn-1 main rail 1 are sequentially connected and conducted, and the n-1 batch of cars on the m-th main rail 1 pass through the m, ..., m+kn- The switching device 2 on one main rail 1 enters the m+kn-1th main rail 1.

This step is similar to step S1. Since step 1 has switched the switching device 2 on the m-th main rail 1 to the switching device 2 on the m+kn-1-1-th main rail 1 to the target position, only the m+kn-th The switching device 2 on one main rail 1 is enough.

Step S4: switch the switching device 2 on the m+kn-1 main rail 1 to switch on two adjacent sections of the m+kn-1 main rail 1 .

According to the above operation sequence, until the first batch of cars on the mth main rail 1 pass through the switching device 2 on the m, ..., m+k1 main rail 1 in turn, and then enter the m+k1 main rail 1 After getting on, switch the switching device 2 on the m+k1 main rail 1 to the two adjacent sections of the m+k1 main rail 1, that is to complete the a car on the m main rail 1 scheduling.

It can be seen from the above that the kn, kn-1, ..., k1 batches of cars are dispatched successively, and are dispatched to the m+kn, m+kn-1, ..., m+k1 main rails 1 respectively. Before the track cutting, a car is located above the switching device 2 of the m-th main rail 1, and the i-th batch of cars passes through the switching on the m, m+1, ... m+ki main rail 1 in turn After the device 2 enters below the switching device 2 on the m+ki main rail 1. Then, after the switching device 2 on the m+ki main rail 1 is switched to the adjacent two sections of the m+ki main rail 1, the i-th batch of cars will then move along the m+ki main rail 1 rises, where 1≤i≤n.

Fig. 3 (b) is the process that the car 4 runs along the route connecting conduction. Fig. 3 (c) is that after the A car arrives at the lower track of the main rail four 14, the switching device 2 of the main rail four 14 switches to the upper track and the lower track of the leading main rail four 14.

The switching device 2 on the m+k2th main rail 1 connects its lower rail with the transition rail 3 on its left side.

Step S4: After the second batch of cars on the m+k2th main rail 1 pass through the switching devices 2 on the m+k2, ..., m+k1, ..., m main rails 1 in sequence Enter the mth main track 1.

Similarly, in this step, the second batch of cars also passes through the transition track 3 between the m+k2 main rail 1 and the m main rail 1 .

According to the above operation sequence, until the switching device 2 on the m-th main rail 1 and the m-th main rail 1 to the switching device 2 on the m+kn-th main rail 1 and the m+kn-th main rail 1 are connected sequentially , the nth batch of cars on the m+knth main rail 1 pass through the switching device 2 on the m+knth main rail 1 to the switching device 2 on the mth main rail 1 and the transition track 3 between them, and then enter the first m main rail 1, complete the scheduling.

It can be seen from the above that the 1st, 2nd..., n batches of cars are dispatched successively, and are dispatched to the m+k1, m+k2,..., m+knth main rails 1 respectively.

In the all-in-one scenario, before the track is cut, the 1st, ..., and n batches of cars go down along the m+k1, ..., m+knth main rail 1 respectively. At this time, the m+th The switching devices 2 on k1, ..., m+kn main rails 1 are all connected to the main rails 1 where they are located.

When the i-th batch of cars goes down to the bottom of the switching device 2 on the m+ki main rail 1, the switching device 2 on the m+ki main rail 1 is switched to connect to the m+ki main rail The lower track of 1 and the transition track 3 on the left side of the m+ki main rail 1 are connected to the switching device 2 on the m+ki-1 main rail 1 through the transition track 3 on the left. Then, the i-th batch of cars goes up through the switching device 2 on the m+ki main rail 1 and enters the transition track 3 between the m+ki main rail 1 and the m+ki-1 main rail 1 , the switching device 2 on the m+ki main rail 1 is then switched to connect the transition rail 3 on the left side of the m+ki main rail 1 and the transition rail 3 on the right side of the m+ki main rail 1, so that the The switch device 2 on the m+ki-1 main rail 1 communicates with the switch device 2 on the m+ki+1 main rail 1, where 1≤i≤n, n≥2.

During the down peak, passengers on different floors need to take the elevator down to the base level, and then leave the building from the base level, that is, more passengers need to go down, and fewer passengers need to go up. At this time, a small number of main rails 1 are set as upward tracks, and many main rails 1 are set as downward tracks. Cars 4 on a plurality of down tracks go down after picking up passengers on each floor, dispatch them to up tracks through the track cutting device after getting off passengers at the grassroots level, and then go up along the dispatched main rail 1. In this embodiment, the mth main track 1 is set as an uplink track, and the m+k1, ..., m+knth main track 1 is set as a downlink track. The car 4 on the down track picks up passengers and goes down on each floor. Obviously, the setting of multiple down tracks greatly improves the efficiency of picking up passengers down. The empty car 4 after going down can be quickly dispatched to the up track by the track cutting device for use in Pick up passengers and provide empty cars for each floor's down demand, and avoid the impact on the car 4 going down on the down track.
