Detailed Description
The following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
As described in the background art, if the working lamp of the excavator is abnormal, it cannot be known in advance, and if the excavator needs construction work at this time, the safety is affected.
Example 1:
the utility model provides an excavator work light fault pre-diagnosis device, includes, installs work light, MCU controller, display and the excavator communication terminal on the excavator organism, and mobile communication equipment passes through high in the clouds server and is connected with excavator communication terminal.
The working lamp is a working illuminating lamp of the excavator, and can illuminate when the engine is started.
And the MCU controller is connected with the working lamp, controls the working lamp to be turned on and off through the DO signal, and detects the accumulated working time of the working lamp.
A current acquisition circuit in the loop acquires the current value of the working lamp, converts the current signal into a voltage signal, and feeds the voltage signal back to the MCU controller through analog-to-digital conversion.
The MCU controller monitors the running state of the working lamp by utilizing the accumulated working time, the current and the voltage and sends the running state to the display. And meanwhile, the running state of the working lamp is sent to the mobile communication equipment through the cloud server by utilizing the excavator communication terminal.
The working lamp comprises a movable arm lamp of the excavator, a cab top lamp and a counterweight lamp.
