The invention provides a parking navigation and finding system based on object networking wireless sensing and video perception, comprising a main control computer. The main control computer is connected with a plurality of park control systems with number plate automatic identification and a plurality of integrated LCD displays with players and wireless stall sensors through a network; the wireless stall sensor is installed at each stall; the park control system comprises a number plate identification system, an RFID (Radio Frequency Identification Device) reader-writer and a matched radio frequency identification electronic tag; and the LCD display comprises a navigation screen at the garage entrance and the LCD display arranged on a client forwarding path. The parking navigation and finding system has the advantages of actively informing a related internal part or a common platform of characteristic vehicle information and having a remote maintenance system transmitted through 3G and is a typical object networking perception system. The parking navigation is precise through an object networking wireless perception technique and a number plate identification technique, a vehicle owner finds a stall efficiently and the identity identification is in advance.

A Mobile Information Search and Knowledge Discovery System Based on Geographic Spatiotemporal Data

The invention relates to a mobile information searching and knowledge discovery system based on geographic spatiotemporal data. The client of the system is based on Android and ios intelligent mobile phone equipment (two realized versions), can obtain the location data such as coordinates, time, height, direction and the like of a user at present and can provide the data to a server through a third-generation (3G) network. The client can download the summery of network information which interests the user and is in a geographic fence around the user from the server. The server can also push anetwork information summary which is of the most significant relationship with the location of the user to the user according to the closeness extent of the relationship between the searched network information and the location of the user. The mobile information searching and knowledge discovery system based on the geographic spatiotemporal data has the advantages that under the situation that public positioning navigation equipment is popularized, results can be mined according to the location data such as the coordinates and the time of the user at present and the social relationship of the location fence, the network information can be reorganized and self-adaptive network information expression based on the location of the user can be formed.
