Problems solved by technology

Since the various operating systems of the paver mostly provide the driving force through the engine of the paver body, the load of the paver is relatively high when it is started. start-up phenomenon
In the existing solutions, the connection between the load and the engine is mostly disconnected through the clutch to reduce the difficulty of starting the engine. However, in the existing solutions, whether the engine can be started normally needs to be judged by humans and depends on the experience of the operator. High, and the accuracy of human judgment is not high, it is easy to affect the normal construction work of the paver

Abstract

The invention provides a paver start control method and a paver. The paver start control method comprises the following steps that a paver starting instruction is received; altitude information and engine temperature information of the paver are acquired; according to the altitude information and the engine temperature information, the working condition state of an engine of the paver is determined; the operation state of a clutch of the paver is controlled according to the working condition state; and the engine is controlled to be started according to the operation state of the clutch, wherein the clutch is arranged between the engine and the working load, and the clutch is used for connecting or disconnecting the engine and the working load so that the engine can be started with the working load or without the working load. According to the technical scheme, the operation state of the clutch can be controlled according to the working condition state of the paver so that the paver can start the engine without the working load in a plateau area or a low-temperature environment, the starting difficulty of the engine is reduced, and the paver is easy to operate.

Description

technical field [0001] The invention relates to the technical field of paver control, in particular to a paver startup control method and a paver. Background technique [0002] At present, the paver is one of the common road construction machines, and it is mostly used in road construction to pave various paving materials. Since the various operating systems of the paver mostly provide the driving force through the engine of the paver body, the load of the paver is relatively high when it is started. start-up phenomenon. In the existing solutions, the connection between the load and the engine is mostly disconnected through the clutch to reduce the difficulty of starting the engine. However, in the existing solutions, whether the engine can be started normally needs to be judged by humans and depends on the experience of the operator. High, and the accuracy of human judgment is not high, it is easy to affect the normal construction work of the paver. Contents of the inve...
