Abstract

The invention discloses engineering machinery, and a control system, a method and a device of an arm support of the engineering machinery. The control system, the method and the device can improve the operation safety of the engineering machinery. The control system of the arm support comprises a high-voltage sensor and a controller, wherein the high-voltage sensor is mounted on the arm support of the engineering machinery, is used for detecting an electrical signal around the arm support, and outputs a signal value according to the strength of the detected electrical signal; the stronger the electrical signal detected by the high-voltage sensor is, the larger the output signal value is; the controller is used for acquiring the signal value output by the high-voltage sensor, and controls a movement direction of the arm support according to the signal value output by the high-voltage sensor; and when the arm support moves to one direction, if the signal value output by the high-voltage sensor is increased along with the time and is greater than a preset alarm threshold, the arm support is controlled not to continuously move to the direction.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an engineering machinery boom control system, method, device and engineering machinery. Background technique [0002] Many current construction machinery have booms, such as elevating fire trucks, cranes, etc. When such construction machinery is working, the boom often moves in the air. Operators need to always pay attention to the position of the boom in the air to prevent Collision accidents occur, especially with aerial electrical equipment. However, due to reasons such as the working environment and distance, it is difficult for the operator to accurately observe the position of the boom in the air. [0003] For example, the elevating fire truck is usually used for fire rescue. The working bucket at the front end of the boom is lifted to a certain height through the boom, and the working bucket is used for personnel rescue. In the prior art, in order to make it ea...
