Individual adaptive pressure increasing and decreasing control method for electronic sphygmomanometer

The invention discloses an individual adaptive pressure increasing and decreasing control method for an electronic sphygmomanometer. The method includes: continuously inflating a cuff sleeved on an upper arm for pressure increasing; detecting pulse wave signals and cuff pressure signals; calculating mean pressure Pv and heart rate S according to the pulse wave signals during pressure increasing, calculating systolic pressure Ps according to the mean pressure Pv, and setting the maximum valve Pm of cuff pressure increasing; when the pressure of the cuff reaches the maximum value Pm, by a control air valve, performing individual adaptive constant-speed pressure decreasing until pressure decreasing is completed and the control air valve is completely opened to empty air. By the individual adaptive pressure increasing and decreasing control method for the electronic sphygmomanometer and the electronic sphygmomanometer, high-quality pulse wave signals with moderate pulse waves, reasonable amplitude and evident envelop features, a premise is provided for further identification and determining of blood pressure parameters, and comfortableness of a to-be-tested person is improved during the whole test. In addition, the method is high in individual adaptive measuring capability.

Crossing turning flow analysis system and method based on base-station signaling data

The invention discloses a crossing turning flow analysis system and method based on base-station signaling data, and relates to the field of road flow analysis. The system comprises a data collectionmodule, a storage module and a processing module. The data collection module is used to obtain latitude and longitude information of a crossing and latitude and longitude information of all base stations of an area to which the crossing belongs, and uploads the latitude and longitude information; the storage module is used to store the latitude and longitude information; and the processing modulecalculates distances between the base stations and the crossing according to the latitude and longitude information of the information and the latitude and longitude information of the base stations,selects all base stations whose distances to the crossing is greater than a threshold alpha and lower than a threshold beta as determining base stations, and divides the determining base stations intoidentification clusters in different directions. The threshold alpha ranges from 100 to 300m, and the threshold beta ranges from 900 to 1200m. Thus, proper base stations can be select to form base station clusters so as to determine vehicle turning.
