Embodiment Construction

[0031] Such as figure 1 As shown, the present invention is aimed at the non-deliberate data collection method of mobile phone sensors, comprising steps:

[0032] A. Establish a connection, including steps:

[0033] A1. The subject turns on the mobile phone, and the mobile phone automatically sends a WebSocket connection request to the background control terminal through the communication channel;

[0034] A2. The control end establishes a connection according to the received WebSocket connection request, and sends the generated UUID (Universally Unique Identifier) ​​as the current connection ID to the mobile phone;

[0035] A3. The mobile phone status corresponding to the current connection of the control terminal identification is not collected, and with the current connection ID as the key, the mobile phone status is the value to establish a key-value pair, and the key-value pair is stored in the Redis database;

[0036] A4. The mobile phone sends the connection ID feedbac...

Abstract

The invention relates to a non-deliberate data acquisition method for a mobile phone sensor, and the method comprises the steps: A, a collected person starts a mobile phone, the mobile phone automatically builds WebSocket connection with a background control end, and generats a connection ID; B, a controller selects a connection ID at a control end, identifies expansion information acquired this time, and sends an instruction of starting acquisition to the mobile phone; c, the mobile phone starts to collect data of a sensor in the mobile phone through a sensor monitor in the mobile phone according to the received instruction, and sends the collected data to the control terminal in real time; d, the control end sends an acquisition stopping instruction to the mobile phone which is acquiringdata through connection with the ID; and E, the mobile phone receiving the acquisition stopping instruction stops acquiring the data. According to the invention, data acquisition can be carried out on a plurality of mobile phones at the same time through one control terminal, data acquisition of normal behaviors can be carried out under the condition that an acquired person does not know acquisition start and stop, and dirty data during acquisition is effectively reduced.

Description

technical field [0001] The invention relates to a data collection method, in particular to a non-intentional data collection method for mobile phone sensors. Background technique [0002] A mobile phone usually has various sensors, including an acceleration sensor, a magnetic field sensor, an orientation sensor, and the like. These sensors can collect data such as the acceleration of the mobile phone along the three-axis direction, the angular velocity of the rotation along the three-axis direction, and the strength vector of the geomagnetic field in real time. At the same time, the behavior of mobile phone holders can also be analyzed through these data. Some data labeling companies provide behavioral data collection services based on mobile phone sensors. The conventional methods used in the collection process are as follows: [0003] The conventional behavioral data collection method is to bury the point, by adding the collection code in a certain process of the behavio...
