Embodiment 1

[0059] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for determining whether a user goes up / down a floor, and the method specifically includes the following steps:

[0060] Step 10, read the values ​​of the built-in three-axis acceleration sensor and digital compass of the user's mobile phone in real time, and judge whether the user is in a state of motion.

[0061] Most of the existing smart phones have a built-in three-axis acceleration sensor and a digital compass, and smart phones have been popularized in a large number. Therefore, it is a feasible method to use the smart phone to locate the user's position. By reading the values ​​of the mobile phone's built-in three-axis acceleration sensor and digital compass in real time, not only can we know whether the user is moving, but also know the direction of the user's movement through calculation.

[0062] Specifically, to determine whether the user is in a state of motion, you can pre-se...

Embodiment 2

[0079] In the user’s up / down floor determination method provided by Embodiment 2 of the present invention, the smart phone’s built-in three-axis acceleration sensor and digital compass value are read in real time, and after correction, the user’s static state or motion state is distinguished by setting a threshold value. In the motion state, through the set two-dimensional plane motion threshold value, it can be distinguished whether the user's motion is in the two-dimensional plane; if it is greater than the two-dimensional plane motion value, it is considered that the user may be climbing stairs; combined with the wireless indoor positioning technology, the current The user coordinates distinguish whether the user is currently in the stairwell. If the user is in an area where up and down stairs may occur, the user is considered to be moving up and down the stairs. Whether the current location can only move in one direction through the map attribute. If the event of going up a...

Embodiment 3

[0083] Embodiment 3 of the present invention provides a device for determining whether a user goes up / down floors, such as figure 2 As shown, the device includes a motion state judging unit 100, a two-dimensional plane judging unit 200, a stair area judging unit 300, an up / down stairs judging unit 400 and a floor judging unit 500, wherein,

[0084] The motion state judging unit 100 is used to read the values ​​of the built-in three-axis acceleration sensor and the digital compass in the user's mobile phone in real time, and judge whether the user is in the motion state.

[0085] The two-dimensional plane judging unit 200 is configured to judge whether the user's movement is on a two-dimensional plane.

[0086] The stair area judging unit 300 is configured to judge whether the user is in the stair area through wireless indoor positioning.

[0087]The up / down stairs determining unit 400 is used to calculate the user's movement direction through the value of the digital compass...

Abstract

The invention discloses a method and a device for determining going upstairs or downstairs of a user. The method comprises the steps of reading values of a triaxial acceleration sensor and a digital compass which are arranged inside a mobile phone of the user and judging whether the user is in a motion state; when the user is confirmed to be in the motion state, judging whether the user moves in a two-dimensional plane; when a condition that the user is not in the two-dimensional plane is confirmed, judging whether the user is in a stair area through wireless indoor positioning; when a condition that the user is in the stair area is confirmed, correcting the output value of the digital compass and obtaining a motion direction of the user; comparing the motion direction of the user with data of directions of going upstairs and going downstairs which are saved in advance and determining whether the user goes upstairs or downstairs; and judging whether the user completes an upstairs going process or a downstairs going process and updating data of the current floor according to a judging result. By the aid of the method and the device, judgment of the user going upstairs or downstairs is achieved, judging accuracy of stairs in an indoor positioning process is greatly improved and user experience are enriched.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a method and device for determining whether a user goes up / down a floor. Background technique [0002] The emergence and development of satellite navigation and positioning technology has enabled people to have a technical method to obtain the spatial location attributes of things in the vast outdoor space around the world. However, most of the time, people's activities are mainly carried out indoors. Since the signal of the GPS in the indoor environment is shielded, the GPS cannot achieve accurate positioning indoors. [0003] There are a variety of solutions for indoor positioning using wireless signals. However, due to the relatively complex indoor environment, weak signals, and serious multipath and reflection phenomena of wireless signals, existing indoor positioning technologies often focus on two-dimensional planes, that is, the same How to improve the position...
