And the position correction mechanism is used for correspondingly adjusting according to the correction instruction so that the terminal moves until the measured values of all the laser range finders are recovered to be normal. In this embodiment, the position correcting mechanism includes a plurality of telescopic brackets 30; each telescopic bracket 30 comprises a contracted state and an expanded state, and the top part thereof is connected to the bottom surface of the base 10 through a universal rotary joint (not shown in the figure); the rotation angle, rotation direction and telescopic state of the telescopic brackets 30 are controlled by the correction control unit, and the terminals move by matching with each other, so that the purpose of correcting the position of the terminals is achieved.
The number of the laser range finders is consistent with that of the telescopic supports 30, the laser range finders are fixedly arranged on the bottom surface of the base 10, and one laser range finder is fixed at the mounting position of each telescopic support 30 and used for measuring the distance between the current position of the base 10 and the table top in real time through laser and feeding the distance back to the correction control unit.
And the correction control unit is used for generating a corresponding correction instruction according to the current abnormal condition when the measured value fed back by one or more laser range finders in real time is abnormal, and controlling the corresponding part of the telescopic bracket 30 to extend and/or rotate so that the terminal moves until the measured value of each laser range finder returns to normal.
Correspondingly, referring to fig. 3, the method for automatically correcting the position of the terminal includes:
and 301, acquiring the measured values of all the laser range finders at the bottom of the terminal in real time.
And 303, controlling the position correction mechanism to correspondingly adjust according to the correction instruction so that the terminal moves until the measured value of each laser range finder returns to normal.
In the method, the correction control unit needs to control the position correction mechanism to adopt different adjustment modes according to different abnormal conditions. For example:
①, when the measured value of at least one laser rangefinder exceeds the preset maximum threshold, it indicates that the terminal is tilted, and a part of the area of the terminal (including the area where the laser rangefinder whose measured value exceeds the preset maximum threshold is located, such as the right half of the terminal) is away from the desktop, at this time, the terminal can be moved by controlling at least one telescopic bracket 30 (such as a plurality of telescopic brackets 30 located in the left half) to be telescopic and tilted until the measured values of all laser rangefinders return to normal;
② when the measured values of all the laser rangefinders decrease and one part of the measured values is larger than the other part of the measured values, it indicates that the terminal is tilted and the edge area of the terminal (excluding the area where all the laser rangefinders are located) is away from the desktop, at which time the terminal can be moved by controlling at least one telescopic bracket 30 to be telescopic and tilted until the measured values of all the laser rangefinders return to normal;

In order to achieve a good position correction effect, as shown in fig. 1, 4 telescopic brackets 30 are adopted in the present embodiment, and each telescopic bracket 30 is symmetrically distributed around a central point of the bottom surface of the base 10 (for convenience of distinction, installation positions of the 4 telescopic brackets 30 are respectively named as position 1, position 2, position 3, and position 4 hereinafter and in the drawings), so that the bottom surface of the base 10 can be divided into four equal regions around the central point, as shown in fig. 1.
Under normal conditions, as shown in fig. 2, the base 10 is horizontally placed on the table top through the supporting column 20, and the telescopic brackets 30 are in the retracted state, and the measurement values of the laser range finders are substantially the same and within the preset standard range.

(5) The upper left corner of the terminal breaks away from the desktop: when the measured value of the laser range finder at the position 1 is increased sharply and is larger than the maximum threshold value preset by the system, the upper left corner of the terminal is considered to be separated from the desktop, the telescopic supports 30 at the positions 2 and 4 are controlled to extend out at the moment, after the extending action is finished, the two telescopic supports 30 are controlled to incline towards the upper left corner, so that the lower right corner of the terminal moves for a certain distance, and then the telescopic supports 30 are retracted and restored to the original state.
(6) The upper right corner of the terminal breaks away from the desktop: when the measured value of the laser range finder at the position 2 is increased sharply and is larger than the maximum threshold value preset by the system, the upper right corner of the terminal is considered to be separated from the desktop at the moment, the telescopic supports 30 at the positions 1 and 3 are controlled to extend out at the moment, after the extending action is finished, the two telescopic supports 30 are controlled to incline towards the upper right corner, the terminal moves towards the lower left corner for a certain distance, and then the telescopic supports 30 are retracted and restored to the original state.
In addition, if there is a sharp increase in the measurement values of the laser rangefinders at position 1, position 2, position 3 and position 4, then the terminal is considered to be manually picked up and the telescopic bracket 30 remains stationary.
Secondly, in the above-mentioned ② abnormal condition, that is, the edge area of the terminal is separated from the desktop
When the measured values of the laser range finders at the positions 1, 2, 3 and 4 are all decreased, and the measured values at the positions 1 and 4 are greater than the measured values at the positions 2 and 3, the edge part of the right side of the terminal is considered to be separated from the desktop, at this time, the telescopic supports 30 at the positions 1, 2, 3 and 4 are controlled to extend out, after the extending action is completed, the four telescopic supports 30 are controlled to incline towards the right side of the terminal, so that the terminal moves towards the left side for a certain distance, and then the telescopic supports 30 retract and return to the original state.
Thirdly, under the ③ th abnormal condition, water accumulation appears at the bottom of the terminal
When the bottom of the terminal meets water, the measured values of the laser range finders at position 1, position 2, position 3 and position 4 at this time can be reduced by substantially the same amplitude, and at this time, the four telescopic brackets 30 are controlled to simultaneously extend out, as shown in fig. 6, the terminal is lifted, so that the bottom of the terminal can be prevented from entering water.
In other embodiments, the number of the telescopic bracket 30 and the laser range finder is not limited to 4, and the position is not limited to the position shown in the figure, and the telescopic bracket 30 may also adopt other implementation structures as long as it can be controlled by the calibration control unit to drive the terminal to move a certain distance in each direction.
