Embodiment Construction

[0070] Below in conjunction with specific embodiment, further illustrate the present invention.

[0071] The purpose of the present invention is to use the spatial activity data sets of mobile terminal individuals within a specified time range to mine a large number of individual travel time-space sequence data, identify the record points with wrong location information in the user travel time-space sequence, and correct the errors including sensor recording errors and the sensor itself. The location information is wrong, so as to solve the problem of jumping the user's travel trajectory caused by it.

[0072] figure 1 The flow chart of the method for judging, identifying and correcting the wrong position of the fixed sensor in the big data environment provided by this embodiment, the method for judging, identifying and correcting the wrong position of the fixed sensor in the big data environment includes the following steps:

[0073] Step 1. The system reads the anonymous encr...

Abstract

The invention provides a method for judging, identifying and correcting a wrong position of a fixed sensor in a big data environment. Massive individual outgoing space-time sequence data is mined by utilizing a space activity dataset of an individual mobile terminal in a designated time range, wrong recording points of the position information in an outgoing space-time sequence of a user are identified, sensor recording errors and sensor position information errors are corrected, and the caused problem of outgoing trajectory skipping of the user is solved. Outgoing trajectories of a large number of populations in the designated time range can be automatically, quickly and conveniently obtained by utilizing continuous encryption position information of massive existing anonymous mobile terminals in a communication network in a low-cost mode, and position errors of target signaling records are corrected by utilizing outgoing trajectories similar to position information error records in the trajectories, so that individual outgoing trajectories are continuous, complete and accurate, and a bottom-layer data foundation is tamped for application and analysis of smart outgoing and smart traffic.

Description

technical field [0001] The invention relates to a method for judging, identifying and correcting wrong positions of fixed sensors in a big data environment, and belongs to the technical field of big data analysis. Background technique [0002] In recent years, with the development of information technology, the amount of data information has shown explosive growth, more and more data sources, and the amount of data has become larger and larger. Among them, data recorded by information sensors such as mobile phones, WIFI, and the Internet of Things has become the most important data source in big data analysis. Its relatively complete individual travel records provide a good basis for big data, especially traffic big data analysis. data support. Taking mobile phones as an example, by 2015, mobile phone users reached 1.306 billion, accounting for more than 96% of the total population. The signal information continuously generated by mobile terminal devices has formed a series...
