The utility model relates to the technical field of
geographic information system application, and discloses a GIS-based
walking time reader for measuring the coverage rate of a park green land, which comprises a bottom shell, an upper cover is arranged at the top of the bottom shell, a display screen is fixedly connected to the middle of the upper cover, a circuit board is arranged in the bottom shell, and the circuit board is fixedly connected with the display screen. An acceleration sensor, a
GPS positioning sensor and a controller are sequentially installed in the middle of the circuit board, a wearing
assembly is installed on the outer side of the bottom shell, and a timing
assembly is further installed in the middle of the circuit board. The timing
assembly comprises a contact switch, a
quartz crystal oscillator, an amplifying circuit, a shaping circuit and a frequency dividing circuit. According to the
system, the acceleration sensor, the GPS, the
timer and the
wireless transmission function are combined, the walking path and time are accurately recorded, data are transmitted in real time, the green land coverage
rate measurement precision is improved, urban planners can dynamically master the actual green land access condition of residents, and a scientific basis is provided for reasonably optimizing the green land
layout.
