Example 1

Referring to fig. 1, in an embodiment of the present invention, an apparatus for assisting a power machine to move straight line includes a cab, a main control computer 01, a display screen 02, an alarm 03, a satellite signal receiver 04, and a communication antenna 05 are disposed in the cab, and the display screen 02, the alarm 03, the satellite signal receiver 04, and the communication antenna 05 are electrically connected to the main control computer 01.

Furthermore, the main control machine 01 is fixed in the cab through self-tapping screws, the fixed position of the main control machine 01 should avoid a severe vibration area as much as possible, and meanwhile, the main control machine 01 comprises a 4G wireless communication module, a multi-mode multi-frequency satellite positioning module, an RTK (real time kinematic) difference module and function keys, and also has a function of setting function points, wherein the working width of the machine can be recorded through the function keys.

Further, the main control computer 01 is in signal connection with the satellite signal receiver 04 through the multi-mode multi-frequency satellite positioning module, and can receive the satellite signal through the satellite signal receiver 04 and calculate the current position.

Furthermore, the main control computer 01 is in signal connection with the RTK differential reference station through the 4G wireless communication module, so that the signals of the RTK differential reference station can be received, the calculated current position is accurate, the error of the position is smaller than or equal to 2.5cm, and the centimeter-level precision is achieved.

Further, the display screen 02 is fixed on the periphery of a steering wheel of the cab through self-tapping screws, and the orientation of the display screen 02 is adjusted through a universal joint support; the display screen 02 has the functions of displaying the positioning precision level, displaying the current movement direction, displaying the movement speed, displaying the elevation, displaying the communication signal intensity, reminding the deviation and the like, wherein the positioning precision level comprises single-point positioning, differential positioning, floating point positioning and fixed solution positioning, and the current position condition can be known in detail through the display screen 02.

Further, the alarm 03 is fixed on the periphery of the driver seat through magic tapes or self-tapping screws and used for alarming in a deviated route, so that an operator can accurately hear alarm reminding sound.

Example 2

Through the difference of operation conditions, two operation methods are included, taking agricultural machinery as an example:

the operation condition one is as follows: single line travelling

1. Before operation, a handheld dotter is used or an agricultural machine is driven to a starting point and an end point which need to advance, the starting point and the end point are respectively set at the starting point and the end point according to the function keys of the main control machine 01, and after the setting is finished, the main control machine 01 automatically connects the starting point and the end point into a planned route;

2. switching the equipment to an operation state, and starting the agricultural machinery to operate;

3. when the agricultural machinery deviates from a planned route in the operation process, the main control computer 01 starts an alarm program, the alarm 03 gives an alarm prompt, and the display screen 02 displays the deviation to prompt an operator of the direction needing to be corrected;

4. when the operator corrects the actual position of the agricultural machine to the planned route, the main control computer 01 cancels the alarm, and the display screen 02 redisplays the normal operation interface.

The second operation condition is as follows: in-zone operation

1. Before operation, a handheld dotting device is used or the agricultural machinery is driven to 4 angular positions of the area respectively, and dotting is carried out at each position; the equipment automatically draws a rectangular area, plans out an agricultural machine advancing track according to the operation width of the agricultural machine and displays the position of the agricultural machine;
