The embodiment provides an operation method of the double-track circulating elevator based on the corridor double-track circulating elevator, which comprises the following specific steps:
s1, a user presses a public end button box in a corridor or presses a private end button box in a home to call, and a system judges whether a vacant seat is available;
s2, selecting an optimal route according to the priority to schedule the idle seat, and calculating the optimal route by the system to schedule;
s201, reading the position of a transport chair according to a preset floor, judging the state of the transport chair and judging the priority;
s202, the running seat is larger than the space seat, the idle seat is searched first, and the transportation seat closest to the idle track is scheduled;
s203, when the running seats are arranged on the track, scheduling the transport chairs by the optimal route, waiting for the transport chairs on the running track to finish the work, generating an idle track after the transport chairs are far away from a user calling layer, and selecting the transport chair closest to the idle track for scheduling;
meanwhile, the main control system judges whether the transport chair is idle; if not, waiting for the idle transport chair, if the idle transport chair is available, the main control judges whether the path conflicts and sends the target floor to the transport chair.
S3, the transport chair runs to a specified floor, a user takes the elevator, and a distance detection module in the signal acquisition unit detects the position information of the current transport chair on the hoisting track; the anti-collision protection detection module detects safety distance information between a current transport chair and the transport chairs respectively in front of and behind; the gravity detection module detects whether the user is overweight and collects whether the user takes information; the alarm unit can be used for prompting the signal acquisition unit to acquire information.
Specifically, in S201, the position of the transport chair is read, the starting point of the first floor point is used to define the length of the elevator in the whole corridor, and the encoder and the up-down counter in the controller are used to determine the current position of the transport chair; judging the state of the transport chair, if one transport chair is moving upwards from the first floor, the value of the counter is in two states, namely, increasing upwards from 0 and decreasing downwards from the maximum value, and the increase and the decrease are judged by the movement direction of the transport chair.
In this embodiment, when the user takes the elevator for use, based on the operation method of the dual-track circulating elevator, the dual-track electric control embodiment is introduced as follows: when a person is ready to go to other floors on a first floor, the person presses a calling button on a calling panel, then presses a face recognition button at a position D1 or directly swipes a card at a position D6 (face recognition or card swiping is not needed during private calling operation in each house), then a system reads transportation-dependent running state information and judges whether a first floor of an idle elevator moving road meets obstacles or not, and if other transportation-dependent rails exist, the system calculates an optimal path and calls an optimal idle elevator. And if the optimal path does not exist, waiting.
When the transport chair receives an instruction and reaches a first floor, the first direct current motor and the second direct current motor are controlled to put down the cushion and the pedals, and the buzzer sounds to prompt a passenger. The passengers or goods select to stand or sit according to the requirements, the safety belts are tied, and the transportation seat enters a passenger carrying operation mode. After the elevator arrives at a designated floor, the arrival lamp and the arrival prompt tone sound are sounded, people can unlock safety belts by themselves, and the elevator enters a standby mode after 30 seconds to wait for an instruction.
Other floor personnel press a D4 uplink button or a D5 downlink button on a call panel, then press a D1 position to realize a face recognition button or directly swipe a card at a D6 position (the face recognition or the card swiping is not needed during private call operation in each house), and when a transport chair arrives at the floor, the elevator enters a passenger carrying operation mode. After the elevator arrives at the appointed floor, the arrival lamp and the arrival prompt tone sound are sounded, and the personnel can unlock the safety belt by themselves. When the transport leans are operated, the control system changes the operation track path into an occupied state to prevent other transport leans from reversely operating.
The following are further descriptions:
as shown in fig. 11, when a user in the fourth floor presses a call elevator to go down, the idle transport chair 2 is at the first floor at the moment, and if the idle transport chair 2 goes up, the idle transport chair 2 collides with the running up-going transport chair 1, and at the moment, the system enables the idle transport chair 2 to go down to a riding point of the fourth floor through another track.
As shown in fig. 12, when a second floor user goes upward and a third floor track has an idle chair 1, the system calls the idle chair 1 to go upward to avoid the operating chair 2.
As shown in fig. 13, when the user on the third floor goes upward, the second floor also goes upward and needs the system to ensure that the distance between the users is not less than two meters, and the transport chair 2 behind the second floor is decelerated correspondingly until the second floor stops. While the transport carriages 3 can run or be dispatched on another track.
In conclusion, the double-track circulating closed-loop device disclosed by the invention utilizes the double-track circulating closed-loop arrangement, improves the problem that the number of transport bodies is small when the traditional tracks are crossed and in operation, has good schedulability and high intelligence degree, improves the transport efficiency and meets the requirement of multi-ladder co-operation.
