Description
Technical Field
The invention relates to the field of elevators, in particular to an elevator call control method and an elevator system using the same.
Background
At present, a calling system of an elevator is simple, and generally, a calling device is arranged at each floor, an uplink button and a downlink button are arranged on the calling device, and the uplink button and the downlink button are used for calling a car with the shortest travel distance from the floor where the current calling device is located to the current floor so as to be taken by passengers. However, after the call device has issued a call signal, there is a possibility that the call device is inserted by a call signal of a call device of another floor, and if an inserted call signal from a large number of floors is encountered, the waiting time of the passenger on the current floor increases, or if the car is already full of passengers before the car reaches the current floor, the passenger on the current floor cannot take the car, and the waiting time of the passenger on the current floor is wasted.
Disclosure of Invention
Based on this, it is necessary to provide an elevator call control method including the steps of:
s1, the passenger inputs a call command through an outbound button, wherein the call command comprises initial floor information and elevator taking direction information;
s2, allocating cars according to the call commands, comprising the following steps:
a1, counting the travel distance d between each lift car and the initial floor in real time according to the initial floor information and the elevator taking direction information, and counting the number n of floors that each lift car needs to stop before reaching the initial floor in real time;
the travel d of each car from the initial floor is the distance which needs to be passed by each car to reach the actual floor according to the current traveling route;
a2, calculating predicted arrival time T required by each car to move to an initial floor through a travel d in real time, wherein T = d/v + n T, v is the rated speed of the car, and T is car door opening time preset by an elevator for passengers to get on and off the car;
the calculation of the estimated arrival time T of the car is carried out, and the time consumed by the acceleration and deceleration process of the car from the acceleration to the rated speed and the deceleration to the stop and the travel distance are small, so that the estimated arrival time T is not greatly influenced by neglecting the time, the travel distance and the time consumed by the acceleration and deceleration process of the car from the acceleration to the rated speed and the deceleration to the stop are neglected, and the calculation amount of the estimated arrival time T is reduced.
In addition, the estimated arrival time of the car can be calculated by the formula T = d/v + n ta by prolonging the time of T, so as to reduce the influence of neglecting the time consumed in the acceleration and deceleration process of the car and the travel stroke on the estimated arrival time T, wherein ta is a time value after T is prolonged, and the time value after T is determined according to the rated speed and the acceleration of the car.
A3, sorting the cars in real time according to the predicted arrival time T from short to long, and respectively recording the cars as a first sequence car, a second sequence car … and an Nth sequence car;
a4, allocating and reallocating the cars in real time, and always allocating the first sequence of cars with the shortest predicted arrival time T to the passengers until all the cars reach the initial floor.
The invention can ensure that the passenger can take the elevator in the fastest time by pre-calculating the predicted arrival time T of each car to send the call command and distributing the shortest time of the predicted arrival time T to the passenger sending the call command, thereby saving the waiting time of the passenger.
Further, step a4 includes a step of monitoring the load state of each car in real time, and if the load of the car is greater than the preset load g and there is no floor of the selected floor between the current position of the car and the starting floor, the car is classified as a full car, the calculation of the predicted arrival time of the car is stopped, and the distribution and the sorting of the car are cancelled until the car is no longer a full car; if the assignment and the ordering of the first-sequence cars are cancelled, the second-sequence cars are ascending to the first-sequence cars and are assigned to the passengers.
The invention can avoid the situation that the passenger cannot enter the car after the car stops at the initial floor where the passenger is located by monitoring the load of the car in real time, thereby avoiding the waste of waiting time of the passenger. The preset load g is preferably the rated load of the car minus the average weight w of an adult.
Further, the statistical method of the number n of floors to be stopped before the car reaches the initial floor is as follows: and acquiring the number x of call commands sent by floors between the car and the initial floor, the number y of floors of the selected floor between the car and the initial floor, and the number z of the call commands and the selected floor at the same time, wherein n = x + y-z.
Further, the method also comprises the step of displaying the number of the car assigned to the passenger and the predicted arrival time T of the car in real time.
In which the car number of the car assigned to the passenger and the estimated arrival time T are displayed to the passenger, the waiting time of which can be known in advance to the passenger so that the customer makes a choice whether to wait or not. The car numbers are numbers for identifying the cars, and are generally provided at landing doors of a hoistway in which the cars are located.
In addition, the invention also provides an elevator system which uses the elevator call control method to control calls.
The principle and effect of the present invention will be further explained by combining the above technical solutions:
the invention can ensure that the passenger can take the elevator in the fastest time by pre-calculating the predicted arrival time T of each car to send the call command and distributing the shortest time of the predicted arrival time T to the passenger sending the call command, thereby saving the waiting time of the passenger.
In addition, the invention can avoid the situation that the passenger cannot enter the car after the car stops at the initial floor where the passenger is located by monitoring the load of the car in real time, thereby avoiding the waste of waiting time of the passenger.
