Problems solved by technology
However, when the mechanical equipment is in normal use, it often happens that the driver turns off the mechanical power at will, causing the cooling fan to stop working.
When the electrical components are in a high temperature state, this random shutdown may lead to damage or accelerated aging of the electrical components, thereby affecting the service life of the electrical components inside the mechanical equipment and increasing the maintenance cost of the mechanical equipment

Embodiment Construction
[0044] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0045] see figure 1 , which is a flow chart of the first embodiment of a method for controlling downtime of construction machinery provided by the present invention.
[0046] In this embodiment, include:
[0047] S101: Monitoring the shutdown command of the mechanical equipment.
[0048] S102: Detect the temperature of electrical components.
[0049] S103: Judging that the temperature of the electrical component satisfies the shutdown condition.
[0050] S104: If the temperature of the electrical component meets the shutdown condition, control the mechanical equipment to shut down immediately.
[0051] S105: Otherwise, control the mechanical equipment to delay shutdown according to the temperature of the electrical component.

The invention provides an engineering machine shutdown control method and device. The method comprises the steps that a shutdown instruction of a mechanical device is monitored; the temperature of an electrical element is detected; if the temperature of the electrical element meets the shutdown condition, the mechanical device is controlled to shut down immediately; if not, shutdown of the mechanical device is controlled to be delayed according to the temperature of the electrical element. By means of the method, shutdown can be carried out only when it is judged that the temperature of the electrical element meets a certain condition, the problem that high-temperature waste heat of the electrical element cannot be dissipated in time is avoided, the fault occurrence is reduced, and the service life of the element is prolonged.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method and device for controlling shutdown of engineering machinery. Background technique [0002] In today's society, construction machinery such as bulldozers have become indispensable operating equipment in project construction. In the general construction environment, the operating environment of these equipment is relatively harsh. They are often operated in the sun for a long time, and these construction machinery are equipped with a large number of electrical components. If the electrical components are overheated, it will be greatly Affect the normal use of construction machinery. [0003] In the prior art, in order to reduce the temperature inside the mechanical equipment, fans are usually used to dissipate heat. However, when the mechanical equipment is in normal use, the driver will often turn off the mechanical power supply at will, causing the cooli...
