Elevator energy saving and storing device and control method

Abstract

The invention provides an elevator energy saving and storing device and a control method. The device comprises a weight measuring device, a calling box, a control device and executing devices. The weight measuring device is used for measuring the weight of people and objects taking an elevator; the calling box is used for detecting the floor position where the people and objects taking the elevator are located and the lifting direction of the people and objects taking the elevator; the control device is responsible for inputting the weight of all the people and objects taking the elevator and the lifting direction of the people and objects taking the elevator and determining the executing device capable of saving energy through optimal computation; transmission devices in the executing devices are alternating-current direct-current alternating-current frequency converters with controllable rectifiers, a bidirectional voltage rising and reducing charger and a storage battery set. When operating efficiency is not changed, every time an elevator car ascends with no load and descends with heavy loads, the system can be in an energy-saving operating state. According to the elevator energy saving and storing device and the control method, buildings wherein two or more elevators operate can operate in the same way for a long time from the view of statistics, energy saving and consumption reducing are obvious, the control principle is clear, the additional cost is low, and safety and reliability are high.

Description

technical field [0001] The invention relates to an elevator traffic method in the field of group elevators (multi-elevator), in particular to an elevator energy-saving energy storage device and a control method. Background technique [0002] Generally speaking, for buildings with multiple stairs, such as residential buildings or office buildings, the basic rule for elevator transportation is to take the nearest elevator, that is, to choose the elevator with the least number of floors away from the person on the elevator. Regardless of which elevator is preferred to bring about energy-saving effects. [0003] According to the operating principle of the elevator, when the empty box is lowered or the light load is lowered, the counterweight drags the car to run and is in a state of power generation. When the person on the elevator reaches about half of the rated counterweight, the person on the elevator and the car work together to drag the counterweight to run, and it is also...

Problems solved by technology

[0005] This method of judging the weight of the person taking the elevator by means of photography has certain practicability, but the disadvantage of this scheme is that it is realized by the hardware circuit, which makes the hardware system complicated and the cost is very high. Very inaccurate, the original data is inaccurate, or the subsequent circuit operation is inaccurate, and the final judgment of which elevator starts to run is also very inaccurate, the practicability and usability are greatly limited, and so far it has not been popularized and applied

[0006] Based on the above, after searching the prior art of traffic rules in the field of group elevators (multi-elevators), it is found that the existing control methods lack accuracy and practicability
