Problems solved by technology
This solution needs to modify the existing ground environment and install multiple magnetic blocks on the ground, which not only increases the cost of the product, but also increases the threshold for the use of the product
In addition, the navigation distance is limited, because of the limitation of the auxiliary navigation equipment, the actual application, the navigation distance is limited

Embodiment Construction
[0025] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.
[0026] Such as figure 1 As shown, a trackless telescopic door correction method based on GPS positioning technology is characterized in that it includes the following steps:
[0027] A. Obtain the coordinates of the starting point and ending point;
[0028] B. Obtain the nose coordinates in real time;
[0029] C. Construct a trigonometric function with the coordinates of the starting point, end point and the nose of the 3 points, and calculate the offset distance and direction of the nose coordinate relative to the straight line where the starting point and the end point are located;
[0030] D. Correct the deviation according to the offset distance and the offset direction, so that the coordinates of the machine head are on the same straight line with the coordinates of the starting point and end point.
[0031] The telescopic d...

The invention discloses a deviation-correcting method for a railless retractable door based on a GPS positioning technology and a deviation-correcting device for the railless retractable door based on the GPS positioning technology. The deviation-correcting method for the railless retractable door based on the GPS positioning technology comprises the following steps of (1) getting coordinates of a starting point door pile and an end point door pile; (2) getting the coordinate of a machine head in real time; (3) building a trigonometric function by the coordinates of the starting point door pile, the end point door pile and the machine head, and then calculating a deviation distance and a deviation direction, relative to the straight line where the starting point door pile and the end point door pile are on, of the coordinate of the machine head; and (4) correcting deviation according to the deviation distance and the deviation direction to enable the coordinate of the machine head, the coordinate of the starting point door pile and the end point door pile be on a straight line. According to the method and the device, a circular hole does not need to be formed in the ground for installing a magnet, so that the cost of the products can be effectively lowered and the usability of the products can be improved; the navigation is without distance limitations, so that the products can be popularized and used on a large scale. The deviation-correcting method for the railless retractable door based on the GPS positioning technology and the deviation-correcting device for the railless retractable door based on the GPS positioning technology are widely applicable to the retractable door field.
Description
Technical field [0001] The invention relates to a telescopic door, in particular to a method and device for correcting deviation of a trackless telescopic door based on GPS positioning technology. Background technique [0002] A telescopic door is a kind of door that can telescopic and move freely to control the size of the door hole and to control the interception and release of pedestrians or vehicles. Telescopic doors are divided into tracked telescopic doors and trackless telescopic doors. The trackless electric retractable door is more beautiful, more convenient to enter and exit the vehicle, and the advantages of reducing the damage of the vehicle to the track and the impact on the vehicle have become an inevitable trend of technological development. [0003] The important technology of the trackless telescopic door is the correction system. The product scheme on the market mainly uses the electronic reed switch and the magnetic block installed on the ground to form a navigat...
