Problems solved by technology

However, some existing pavers that use microcomputer controllers usually have poor stability at ultra-low speeds (~1m / min), and cannot adapt to the needs of heavy-duty ultra-low-speed operations; most of the displays are in English, and no Chinese characters are used. It is extremely inconvenient for users; at the same time, there are no basic paver operation data monitoring and fault diagnosis functions, and there are no obvious reminders in terms of use and maintenance

Abstract

An intelligent control system of a spreader is one adopting CAN bus EPEC mirocomputer controller and GRAF pattern display to monitor and control a spreader. The system can smoothly realize travel, direction changing forward and backward functions and constant spreading travel and super low consumtant speed contrl. The system applies Chinese words display, which is direct and straight. It can design and modifying spreading travel speed and turn-over radius and monitor actual travel speed and turn-over radius. It can monitor engines, and over alloperation parameters instead of part conventional instruments, makes routine maintenance prompt and mointor and alarm including over high water temperature, over low engine oil pressure and calibrate and rectify part parameters at site.

Description

technical field [0001] The invention belongs to the control system of construction machine paver, in particular to an intelligent control system of paver. The utility model is a device and method for paver driving control, status parameter monitoring, and Chinese character display using a CAN bus-based EPEC microcomputer controller and a GRAF graphic display. Background technique [0002] Pavers (asphalt concrete pavers, stabilized soil pavers, multi-purpose pavers, etc.) are usually driven by hydraulic drive. The power of the internal combustion engine, through the driving hydraulic pump to the driving hydraulic motor, drives the paver driving mechanism (wheel side reducer + track system / tire system) to realize various functions such as driving, steering, forward and reverse of the paver. Generally, the variable pump is used to realize the stepless speed change of the paver's driving speed, and the conversion of paving and non-paving driving gears is realized by changing t...
