Problems solved by technology
Specifically, the suspension lifting system includes three suspension lifting modes: single point, multi-point and overall lifting. Different suspension lifting modes correspond to different operations, and misoperations are easy to occur during use. This requires a system that can adapt to these three at the same time. Electrical system of a suspension lifting mode

The invention provides an electrical system for a suspension lifting system of an engineering vehicle. The electrical system comprises a programmable logic controller (PLC), and a rising switch, a falling switch, a handle and a suspension lifting system, wherein the PLC establishes a handle operating direction judgment truth table according to a handle operation signal, and judges an effective direction of the truth table, an on-off state of the rising switch and an on-off state of the falling switch according to a handle operating direction to establish an output truth table for combined control of the suspension lifting system; and the PLC receives the handle operation signal, the on-off state of the rising switch and the on-off state of the falling switch, sequentially searches the handle operating direction judgment truth table and the output truth table for combined control of the suspension lifting system, and then obtains a combined control instruction of the suspension lifting system.
Description
technical field [0001] The invention relates to a suspension lifting system, in particular to an electrical system and a control method for the suspension lifting system of an engineering vehicle. Background technique [0002] Many engineering vehicles for large-scale transportation are equipped with electronically controlled hydraulic suspension lifting systems, which are used to adjust the level of the vehicle body to ensure the stability of the vehicle; at the same time, local lifting adjustments are also made to facilitate use and maintenance. Specifically, the suspension lifting system includes three suspension lifting modes: single point, multi-point and overall lifting. Different suspension lifting modes correspond to different operations, and misoperations are easy to occur during use. This requires a system that can adapt to these three at the same time. An electrical system in suspension lift mode. [0003] In order to solve the above existing problems, people hav...
