Abstract: An elevator operation quality detecting system and a detecting method. The system comprises an elevator operation quality detector; the elevator operation quality detector comprises a power supply having a charging function, a central processing module, and a data transmission module, a data storage module, a data acquisition module and a touch display module which are connected to the central processing module; the data acquisition module is connected to a signal sensing module; the signal sensing module comprises a tri-axial acceleration sensor and a tri-axial angular velocity gyroscope which are both connected to the data acquisition module; the data transmission module comprises a GPRS wireless transmission module and a USB interface circuit which are both connected to the central processing module; the central processing module is a DSP main controller.

Abstract: A long-endurance self-powered ocean buoy includes a buoy body, a power generation device and a gas bag base; the power generation device is mounted at a lower end of the gas bag base and includes a housing, a first power generation assembly, a second power generation assembly and a storage battery; the first power generation assembly includes a plurality of mutually-communicated gas chambers, hydraulic bags and control integration units. The lowest gas chamber is filled with a volatile working medium which can generate gas pressure by volatilization to drive power generation fans in turbines on a vent pipe communicating adjacent gas chambers for power generation. The second power generation assembly includes a plurality of temperature difference energy modules with one end surrounded by a phase change material and the other end in contact with the housing, so as to increase the power generation efficiency.
