Problems solved by technology

[0002] Existing construction machinery monitors all use programmable PLC, which requires multiple single-chip microcomputer control circuits. The circuit structure is complex, and data interaction between multiple single-chip microcomputers reduces the reliability of the system; and the functions realized by the system are relatively simple. The human-computer interaction ability is poor, which leads to relatively low work efficiency; in addition, the existing construction machinery monitors are too dedicated to be used on various construction machinery, and the high cost leads to an increase in cost

Abstract

The embedded engineering machine monitor includes control center to send command, lower computer to transmit information upwards, and monitor comprising casing, display, keyboard, power supply interface, serial port, USB port, JIAG port, CAN port, power switch, reset switch and circuit board inside the casing. The circuit hardware structure includes ARM architecture 32 bit embedded microprocessor as kernel, great capacity external memory, keyboard interface circuit, liquid crystal screen interface circuit, CAN bus interface circuit, RS232 interface circuit and USB interface circuit. The software structure is opened source code real-time operation system. The monitor has high integration degree and performance / cost ratio and simple structure and makes it possible to realize intelligent monitoring of engineering machine economically.

Description

technical field [0001] The invention relates to a monitoring device for controlling construction machinery, in particular to an embedded construction machinery monitor. Background technique [0002] Existing construction machinery monitors all use programmable PLC, which requires multiple single-chip microcomputer control circuits. The circuit structure is complex, and data interaction between multiple single-chip microcomputers reduces the reliability of the system; and the functions realized by the system are relatively simple. The human-computer interaction ability is poor, which leads to relatively low work efficiency; in addition, the existing construction machinery monitors are too dedicated to be used on various construction machinery, and the expensive expenses lead to an increase in cost. Contents of the invention [0003] The purpose of the present invention is to provide a construction machinery monitor b...
