[Abstract]:With the rapid growth of national economy, the gradual improvement of people's living standard and quality of life, and the rapid construction of urban modernization, elevators have become an indispensable part of human life. China's total energy consumption surpassed its previous number one, the United States, in 2010, according to figures from the French statistics company. At present, China needs a large amount of energy, but due to its own energy constraints, the energy supply is becoming more and more serious. Therefore, it is urgent for our country to implement the strategy of sustainable development in an all-round way, and to carry out energy conservation and emission reduction to the end. The use of energy-saving elevators greatly reduces energy loss and has significant economic and social benefits. This paper has realized the design of elevator energy saving, first of all has understood the elevator energy saving research background and the significance, is the response to support the national sustainable development, the energy saving and emission reduction action, has briefly understood the domestic and foreign research on the energy saving elevator. The characteristics and application of super capacitor are further understood. The overall design scheme of energy saving of elevator is completed. The energy generated in the state of elevator power generation is stored by super capacitor. When the main power system is short of energy supply, the energy stored in the super capacitor can be released, which plays the role of an auxiliary power supply. Secondly, the basic requirements of energy saving of elevator, the structure composition and working principle of super capacitor energy storage system are briefly introduced, and the running condition of elevator and the work done in electric state and power state are analyzed. The main components of the elevator energy saving system, such as super capacitor group, digital signal processor chip, current sensor and voltage sensor, are selected and their parameters are given in detail. This paper introduces the two-way DC-DC converter and chooses the non-isolated converter for the design of this paper. The hardware circuit of elevator energy saving is designed, which mainly includes power supply system. The type selection of double channel low voltage differential power regulator is carried out, and the specific choice is TPS767D318. For the design of weak current control circuit, the emphasis is on the design of DSP core control circuit and signal conditioning circuit. The design of the high power control circuit is mainly about the surge voltage absorption circuit of switch tube and the super capacitor voltage equalizing circuit. Finally, the control algorithm and software design are realized, the working mode of the converter is analyzed, the controller is designed, and the overall design of the program and the design structure of the main subprogram are given. The design structure is expressed in the form of flowchart. In this paper, the stable charging and discharging operation of the controller to the super capacitor energy storage device is realized, and the purpose of energy saving is realized.
