Method, handheld terminal and system for generating construction machinery control signals

Abstract

The invention discloses a method, a hand-held terminal and a system for generating engineering machinery control signals. The method includes: detecting whether the switch is in the standard input state; when the switch is in the standard input state, collecting mode information input by the user at predetermined time intervals; and sending the mode information to the controller when the mode information input by the user is collected information such that the controller sends standard control signals associated with the mode information to the crane. The present invention can automatically generate corresponding control signals to replace the input of the handle according to different working conditions and mode information input by the user, and can intuitively display the current mode status on the display. Convincing, to achieve the consistency of testing standards, to avoid the impact of differences in manual operations.

Description

technical field [0001] The invention relates to the field of engineering machinery automatic control, in particular to a method for generating engineering machinery control signals, a handheld terminal and a system. Background technique [0002] Large-tonnage cranes usually use CAN (Controller Area Network, Controller Area Network) handles to control the crane's slewing, telescopic, luffing, hoisting and other operations. The CAN handle converts the operation actions of the operator into CAN messages and sends them to the boarding controller through the transmission cable, thereby controlling the crane boarding to perform corresponding actions. The output signal of the handle is sent to the boarding controller through the transmission cable in the form of CAN message, and the boarding controller controls the crane to make corresponding actions according to the corresponding signal. [0003] In the process of crane control testing, due to the unspecified operators and often ...

Problems solved by technology

[0003] In the process of crane control testing, due to the unspecified operators and often relying on personal subjective wishes to operate, there are differences in the operation process and operation methods on different cranes of the same model, which has become the biggest obstacle to the processing of later test data and crane performance evaluation.
