Embodiment

[0060] Step 1. The operator draws a line on the smart mobile terminal to set the walking path of the smart car, such as Figure 4 , where A is the starting point, dots B and E are pause points, C and D are inflection points, and F is the end point. Sections AB and DE represent the ripple section of hand shaking when drawing a line;

[0061] Step 2: The smart mobile terminal collects the path defined by the operator, and extracts the coordinates of the starting point of the path A (Xa, Ya), the coordinates of the pause point B (Xb, Yb), E (Xe, Ye), and the end point F (Xf, Yf). coordinate;

[0062] Step 3: filter the path, and then perform smoothing, and then extract the coordinates C(Xc,Yc) and D(Xd,Yd) of each inflection point, such as Figure 5 ;

[0063] Step 4. Extract the interpolation point coordinates: such as Figure 6 As shown, insert several insertion points M1~M29 between the AB segments, and calculate the coordinates of the next insertion point M1(Xm1,Ym1)~M29(X...

Abstract

The invention relates to a method and a system for scribing and setting a walking path of an intelligent trolley based on a mobile terminal. The method comprises the following steps: scribing and setting the walking path; extracting coordinates of a starting point, a break point and an end point of the path; performing filtering processing on the path, performing smoothing processing on the path, and then extracting coordinates of each inflection point; extracting coordinates of an insertion point; forming a path coordinate table; forming a path coordinate and speed table; transmitting a movement control signal to the intelligent trolley. The system comprises an intelligent mobile terminal and the intelligent trolley; the intelligent mobile terminal comprises a first WIFI (Wireless Fidelity)-to-serial port module, a micro-processing module and a liquid crystal touch screen module; the intelligent trolley comprises a second WIFI-to-serial port module, a single chip microcomputer module, a gyroscope module, a motor driving module and a motor. According to the method and the system, the walking path of the intelligent trolley is scribed and set through the intelligent mobile terminal; the walking path of the intelligent trolley can be changed quickly and conveniently without paving a physical leading line on the ground or managing or maintaining the physical leading line; materials, labour and time are saved.

Description

technical field [0001] The invention relates to the field of smart cars, in particular to a method and a system for setting a walking path of a smart car based on a mobile terminal. Background technique [0002] At present, some automatic warehouses and automatic workshops use tracking smart cars to carry out material handling operations. It is necessary to plan and lay guide lines on the ground in advance, which consumes materials, labor and time. Once the guide line is polluted or damaged, it will affect the handling operation of the smart car. In terms of management, it is necessary to increase the regular inspection and maintenance of the guide line, which increases the workload of management and maintenance; once the warehouse or workshop needs to be re-planned and arranged, manual work is required. Modifying the guide line is still expensive, laborious, and time-consuming. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to impr...
