Embodiment

[0096] The elevator of the present invention includes a car, an elevator controller for controlling the operation of the elevator, and an elevator drive system that provides driving force for the car to go up and down in the hoistway under the control of the elevator controller, including a power supply, a power converter, a motor and its pulleys (for induction motors may also include a reduction mechanism). The rated load of the car is Load norm , the limit of the allowable load of the car is Load limit , and satisfy Load norm ≤Load limit . The rated speed and rated acceleration of the car are respectively v norm and Acc norm .

[0097] see figure 1 As shown in the implementation flow diagram of the control method of the elevator of the present invention, it can be seen that the whole implementation process includes six steps:

[0098] Step 1: The load detection unit of the variable speed elevator detects the actual load Load of the car. The load detection unit may b...

Abstract

The invention discloses an elevator which comprises a car, an elevator controller and an elevator driving system, wherein the elevator controller is used for controlling operation of the car, and the elevator driving system is used for supplying driving force to the car in a hoist way under control of the elevator controller. The actual load upper limit (Load m) of the car meets the relation that Load norm<=Load m<=Load limit. The Load m of the car is obtained by solving an elevator transporting efficiency target function. The elevator driving system controls operating of the car under control of the elevator controller according to the size relation between the actual load (Load) of the car and the Load m. The elevator can effectively reduce the number of people waiting for the elevator in the passenger flow peak period and relieve the crowded condition of an elevator hall, achieves the maximum elevator transporting efficiency, reduces elevator energy consumption and shortens the elevator waiting time of passengers corresponding to the load upper limit increasing. The invention further discloses a control method of the elevator.

Description

technical field [0001] The present invention relates to an elevator. The invention also relates to an elevator control method. Background technique [0002] In the prior art, elevators with variable maximum running speed and / or maximum running acceleration are mainly divided into two categories: [0003] The first category: using the characteristic that the drive torque required by the traction elevator is less than the maximum torque that its drive system (usually the electrical capacity of the elevator drive system) can provide when it is not fully loaded or not loaded, through increasing Increase the speed and / or acceleration of the elevator to shorten the running time of the elevator, so as to improve the driving efficiency of the elevator, such as the Chinese invention patent application publication specification CN1302975C ​​(application number: 02804733.8, date of authorization: March 07, 2007). Obviously, this technical solution is to improve the elevator transport...
