Abstract
A timing reminding method and reminding apparatus for a height-adjustable table. According to the method, by detecting whether a timing starting condition is currently achieved, detecting a posture of a user, and determining a reminding time and starting timing, the user can be reminded to adjust the use posture of the height-adjustable table conveniently and accurately in time. The timing reminding apparatus implements the above timing reminding method.
Claims17
A timing reminding method for a height-adjustable table, comprising:
- detecting whether a timing starting condition is currently achieved, wherein the timing starting condition is that a user is in front of the height-adjustable table;
- wherein whether the user is in front of the height-adjustable table is detected by a pyroelectric infrared sensor and another sensor selected from a first distance measure sensor, a thermal imaging sensor, or an image identification sensor;
- after the pyroelectric infrared sensor detects a thermal infrared signal, then
- the first distance measure sensor starts and detects the distance between the user and the height-adjustable table, and if the distance between the user and the height-adjustable table is greater than a preset distance, a controller judges that the user is not in front of the height-adjustable table;
- and when the distance between the user and the height-adjustable table is less than the preset distance, and the duration reaches a preset time, the controller judges that the user is in front of the height-adjustable table, wherein the another sensor is the first distance measure sensor;
- the thermal imaging sensor starts and continuously detects the thermal infrared signal for a preset time, the controller judges that the user is in front of the height-adjustable table, or otherwise, the controller judges that the user is not in front of the height-adjustable table, wherein the another sensor is the thermal imaging sensor;
- or
- the image identification sensor starts and identifies an image, when the identified image is a preset user, and after the time of continuously identifying that the user is in the image reaches a preset time, the controller judges that the user is in front of the height-adjustable table, or the controller judges that the user is not in front of the height-adjustable table, wherein the another sensor is the image identification sensor;
- detecting a use posture of the user, determining a corresponding reminding time according to the use posture, and starting timing;
- and
- when the user maintains the same use posture until a preset reminding time is reached, reminding, by a reminding unit, the user of the height-adjustable table to change the use posture.
