Equipment, method and system for recording movement trace of boom and engineering machinery equipment

Abstract

The invention discloses equipment, a method and a system for recording movement trace of a boom, and engineering machinery equipment including the system. The equipment comprises a receiving device and a recording controller, wherein the receiving device is used for receiving the rotation angle, the variable amplitude angle and the telescopic length of the boom, as well as the swinging directions of a rotary handle, a variable amplitude handle and a telescopic handle, and the swinging directions include no swinging, forward swinging and backward swinging; the recording controller is connected with the receiving device to record the rotation angle, the variable amplitude angle and the telescopic length of the boom of the boom at the time when the swinging direction of any one of the turning handle, the variable amplitude handle and the telescopic handle changes, as well as the swinging directions of the turning handle, the variable amplitude handle and the telescopic handle. As a result, the equipment, the method and the system for recording the movement trace of the boom disclosed by the invention can both improve the data validation and reduce the requirement on controller and storing device.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a device, method and system for recording the movement track of a boom and construction machinery equipment including the system. Background technique [0002] In the ladder fire truck, it is necessary to record and save the trajectory of the boom movement, so that it can be used when the boom reciprocates or the boom is retracted during the fixed-point high-altitude rescue process. Most of the existing recording methods adopt a continuous high-speed recording method, that is, the position of the boom is recorded every other time (for example, one tenth of a second), and the recording is continuous. Afterwards, according to the recorded trajectory, the boom can be reversed to retract the boom. [0003] However, the existing continuous timing high-speed recording method has high requirements on the speed of the controller and memory, and after the recording starts, i...

Problems solved by technology

[0003] However, the existing continuous timing high-speed recording method has high requirements on the speed of the controller and memory, and after the recording starts, if the boom has a low speed or stops, the data validity of the high-speed recording is not high
