Abstract: The invention relates to the field of information sharing, in particular to an urban private parking space sharing and exchanging service method and system. A parking space supply side sets parking space sharing information and releases the parking space sharing information on a sharing platform, and then an intelligent parking space lock is triggered to conduct locking; a parking space demand side acquires the parking space sharing information within a preset range, so that a parking space sharing information set is formed; the parking space demand side selects a parking space corresponding to the parking space sharing information from the parking space sharing information set and sets a time to leave the parking space. Urban private parking space information is shared, and the utilization rate of parking spaces is increased.

Abstract: A photocatalyst sterilization device includes a housing, wherein the housing includes a first receiving chamber and a second receiving chamber that are in communication with each other, the first receiving chamber receives a photocatalyst layer and a light source assembly configured to irradiate the photocatalyst layer, the second receiving chamber receives an axial-flow fan; and an air inlet and an air outlet are defined in the same surface of the housing, one of the air inlet and the air outlet is corresponded to the first receiving chamber in position, the other one of the air inlet and the air outlet is corresponded to the second receiving chamber in position, and a direction in which the axial-flow fan suctions air via the air inlet is parallel to a direction of irradiation of the light source assembly.

Abstract: An accidental tumbling monitoring method, system and a terminal are disclosed. When a human wearing intelligent shoes is in an accidental tumbling state, whether or not a first inclination angle of soles of the intelligent shoes is restored to a preset inclination range within a first preset time range is determined. If the human tumbles seriously, positioning information of the human wearing the intelligent shoes is sent to a guardian, whether or not a monitoring platform receives feedback information from the guardian within a second preset time range is determined, if not, the monitoring platform sends first aid information of the human wearing the intelligent shoes to an emergency center, and therefore, the situation that the human wearing the intelligent shoes has an accident due to belated treatment is avoided.

Abstract: A parking lot entrance recognition method comprises the steps: reading GPS data of all vehicles appearing in a specified region within a specified time one-by-one; acquiring discontinuity points after it is confirmed that vehicle position information is lost; and comparing the discontinuity frequency of each discontinuity point with a frequency threshold to determine whether or not the discontinuity point is an entrance of an underground parking lot. In this way, the entrances of parking lots can be rapidly positioned, so that drivers can park conveniently and can also drive purposefully; and meanwhile, based on the analysis of the GPS data, the positioning accuracy is higher.
