Description

Technical Field

[0001] The present invention belongs to the technical field of engineering vehicles, and more specifically, relates to a monitoring device for a marker light of an engineering vehicle. Background Art

[0002] There are marker lights installed on both sides above the front and rear buffer beams of the engineering vehicle. The engineering vehicle is equipped with two front and rear driver operating platforms. Two button switches are installed on the front and rear driver operating platforms to control the front marker lights and rear marker lights respectively. Figure 1 As shown: Figure 1 EL1.1 and EL1.2 are the front-end marker lights of the engineering vehicle, EL2.1 and EL2.2 are the rear-end marker lights of the engineering vehicle, SA1.1 and SA2.1 are set on the front driver's operating console to control the front-end marker lights and the rear-end marker lights respectively, and SA1.2 and SA2.2 are set on the rear-end driver's operating console to control the front-end marker lights and the rear-end marker lights respectively.

[0003] At present, the control of the marker lights of engineering vehicles is too simple and has no connection with the running and braking operations of the engineering vehicles. That is, the running and braking operations must be performed, and the corresponding marker lights must be manually turned on according to the working conditions of the engineering vehicles. The operation is cumbersome and prone to errors. For example, when the engineering vehicle is moving forward, the driver needs to put the direction control switch in the forward position, and at the same time, operate the working switch of the rear marker light to turn on the marker light. In addition, the marker lights are installed outside the body of the engineering vehicle, and the marker lights cannot be seen on the vehicle. It is very inconvenient to observe the status of the marker lights by getting off the vehicle.
