With the development of economic, energy shortages as one of the main factors limit the development in every fields. In recent years the construction industry and transport industry has made rapid progress, and the elevator has also been more and more widely used, but energy-hungry as the elevator of its energy consumption is very alarming. Therefore, the study on energy-saving elevator control technology is of great social significance and economic value.In this paper, energy-saving control system of elevator is designed based on the super-capacitor, and the main jobs are as follows:First of all, the overall demand on the system is analyzed, based on which the overall energy saving control system is designed, including the structure and function of the whole system design, system control structure design, hardware and software design.The operational characteristics of the elevator system, elevator running speed and power characteristics of the process are detailed analyzed, and the energy needs and feedback power during the running process were calculated and based on the completion of which the key component of the system-super-capacitor is selected; at the same time, voltage balanced devices in super-capacitors have also been analyzed and compared with the selection.The hardware circuit design is completed:the details of the BUCK/BOOST converter and a variety of signal transducer selection are presented, and using the high performance DSP chip as the core of the control system, the control system hardware circuit is designed including power modules, segregation-driven, communications and display hardware module, and so on.Energy saving control system algorithm is designed and software system is developed; design PI for DC/DC converter control switch off the device and complete system control; modular software design methods are used to develop control module, communication module, display module, signal conditioning modules and protection module program, etc.The hardware and software modules of the system are debugged, and the results are analyzed. Finally, research is summarized and prospects.
