Problems solved by technology
Even if the warning light hardware itself realizes a variety of working mode functions, it is also fixed in advance, cannot be adjusted flexibly, and the design is complicated
When the engineering maintenance vehicle is required to have two or more operating modes, and the warning lights need to be flexibly adjusted to different working modes under different operating modes, the existing technology is helpless

Embodiment Construction
[0015] A method for controlling the working mode of a warning light of an engineering maintenance vehicle, the control steps of which are as follows: figure 1 as shown,
[0016] (1) Determine the operating mode of the engineering vehicle, and distinguish whether the operating mode is normal mode or speed limit mode;
[0017] (2) When the operating mode is normal mode and the speed is greater than 10km / h, the PLC module sets the output channel to a high level, and the warning light is required to be always on; when the vehicle speed is not greater than 10km / h, the PLC module sets a low level to the output channel Ping, the warning light is always off. When the operating mode is the speed limit mode and the speed is greater than 10km / h, define an input signal variable, make the initial value of the input signal variable high level, and then delay it for 1 second through the PLC module and change it to low level and transmit it to the output channel , so that the warning light ...

The invention discloses a method for controlling operation modes of a warning lamp for an engineering maintenance vehicle, and aims to meet the requirement that an engineering vehicle in different operation modes requires the warning lamp to be in different operation modes. The control method includes steps: firstly, judging operation modes of the engineering vehicle; secondly, judging speed of the engineering vehicle when the operation mode is a normal mode, keeping the warning lamp normally on when the speed is larger than a preset speed value, and otherwise keeping the warning lamp normally off; and thirdly, judging speed of the engineering vehicle when the operation mode is a speed limiting mode, keeping the warning lamp glittering when the speed is larger than the preset speed value, and otherwise keeping the warning lamp normally off. Using the method can meet the requirement that the engineering vehicle in different operation modes requires the warning lamp to be in different operation modes, updating programs and adjusting operation modes at any time can be realized, and excessive investment on hardware is not needed while flexible adjustment according to practical demands can be realized.
Description
technical field [0001] The invention relates to the field of railway industry and engineering maintenance vehicles, in particular to a method for controlling the working mode of a warning light of an engineering maintenance vehicle. Background technique [0002] Lighting equipment usually has two states of light on and light off. The existing engineering vehicle warning lights do not work according to the lighting mode that can be flexibly set. Although the flashing work mode has been realized, it only works according to a fixed flashing mode. Even if the warning light hardware itself realizes a variety of working mode functions, it is also fixed in advance, cannot be adjusted flexibly, and the design is complicated. When the engineering maintenance vehicle is required to have two or more operating modes, and the warning light needs to be flexibly adjusted to different operating modes under different operating modes, the prior art is helpless.
