Abstract

A line scribing method of a line scriber includes the steps of providing an electronic map; planning a line scribing path on the electronic map; converting the planned line scribing path into a plurality of planned geographical coordinates; transmitting the planned geographical coordinates to a line scriber; positioning a location to be scribed by the line scriber via a satellite connection to generate a positioning coordinate; comparing the positioning coordinate with an starting geographical coordinate of the planned geographical coordinates, and correcting the planned geographical coordinates according to the difference between the positioning coordinate and the starting geographical coordinate if the positioning coordinate is unequal to the starting coordinate, or moving the line scriber according to the planned geographical coordinates sequentially to perform a line scribing operation if the positioning coordinate is equal to the starting coordinate, so that the line scriber can perform a line scribing operation accurately.

Claims

1. A line scribing method of a line scriber, comprising the steps of:

(S101) providing an electronic map;

(S103) planning a line scribing path on the electronic map;

(S105) converting the planned line scribing path into a plurality of planned geographical coordinates;

(S107) transmitting the planned geographical coordinates to a line scriber;

(S109) positioning a location to be scribed by the line scriber via a satellite connection to generate a positioning coordinate;

(S111) comparing the positioning coordinate with an starting geographical coordinate of the planned geographical coordinates, and executing the steps (S113) and (S115) if the positioning coordinate is unequal to the starting coordinate, or executing the step (S115) directly if the positioning coordinate is equal to the starting coordinate;

(S113) correcting the planned geographical coordinates only according to the difference between the positioning coordinate and the starting geographical coordinate; and

(S115) moving the line scriber according to the planned geographical coordinates sequentially to perform a line scribing operation.

2. The line scribing method according to claim 1, wherein the step (S115) further comprising:

(S115a) comparing a line scriber geographical coordinate of the line scriber with a corresponsive planned geographical coordinate anytime while the line scriber is moving, and executing the steps (S115b) and (S115c) if the line scriber geographical coordinate is unequal to the planned geographical coordinate, or executing the step (S115c) directly if the line scriber geographical coordinate is equal to the planned geographical coordinate;

(S115b) correcting the moving direction of the line scriber according to the difference between the line scriber geographical coordinate and the corresponsive planned geographical coordinate; and

(S115c) moving the line scriber according to the planned geographical coordinates sequentially to perform a line scribing operation.

3. The line scribing method according to claim 2, wherein the steps (S101), (S103), and (S105) are executed by a line scribing path planning host system.

4. The line scribing method according to claim 2, wherein the step (S107) performs the transmission operation via a wireless transmission method.

5. The line scribing method according to claim 1, wherein the steps (S101), (S103), and (S105) are executed by a line scribing path planning host system.

6. The line scribing method according to claim 5, wherein the step (S107) performs the transmission operation via a wireless transmission method.

7. The line scribing method according to claim 1, wherein the step (S107) performs the transmission operation via a wireless transmission method.
