Abstract

A method for calculating the running speed of a multi-car elevator based on a safety distance, which belongs to the technical field of elevator control, is characterized in that: Step 1: Obtain the number n of all cars in the hoistway; the number n of cars is greater than or equal to 2; the step 2: variable i=1, and set a unique car number for each car; the value range of the number is greater than or equal to 1 and less than or equal to n; step 3: obtain the position of car i; the car i is the car numbered i; the present invention realizes the speed control of each car in the multi-car elevator system according to the safety distance, improves the safety of the multi-car elevator system, and reduces To increase the risk of car collision accidents, by referring to parameters such as car position, car free running speed, collision avoidance speed and leveling speed, and comprehensively considering the reaction time of the car system and the action time of the braking device, the present invention can be more accurate Reasonably control the speed of the car.

Description

technical field [0001] The invention relates to a calculation method, in particular to a method for calculating the operating speed of a multi-car elevator based on a safety distance, and belongs to the technical field of elevator control. Background technique [0002] Elevators are an indispensable means of vertical automatic transportation in high-rise buildings. As the scale of buildings increases, a single elevator can no longer relieve the pressure of elevator passenger flow in high-rise buildings. Usually, it is necessary to centrally arrange multiple elevators to deal with the passenger flow during peak hours. . The increase in the number of elevators has also led to an increase in building energy consumption and space occupied by the shaft, and the operating cost of the construction cost has also increased. If you want to reduce the construction cost, this requires reducing the building space occupied by the elevator shaft as much as possible. Since the multi-car el...
