Specifically, when the key panel 130 is in the closed state and the light intensity value is lower than the preset value, the power management module 140 controls the work light 150 to be turned on. When the key panel 130 is in the off state, the power management module 140 controls the working light 150 to be turned off.

Thus, the operator may turn on the key panel 130, the light sensor 110, the display screen 120, the power management module 140 and the work light 150 to process the standby state if necessary, and when the light sensor 110 detects that the light intensity value reaches the preset condition, the work light 150 is turned on for a predetermined time to provide sufficient illumination and time for the operator to complete the operation.

The operator may turn off the key panel 130 if the operator does not need to turn on the working light 150, so that the power management module 140 does not turn on the working light 150 regardless of the intensity of the environment.

The night auxiliary lighting system 100 also has the advantages of adjustable time, intellectualization and no conflict with the power failure of the whole vehicle, and CAN control the working time of the working lamp 150 after flameout through the display screen 120 by the CAN bus communication between the display screen 120 and the power management module 140, thereby completing auxiliary lighting.

s1: and detecting the light intensity value of the environment.

Wherein, the light intensity value of the detection environment can be realized by using the photosensitive sensor 110.

S2: and controlling the working lamp 150 to be turned on or off according to the intensity of the light intensity value and the starting and stopping conditions of the auxiliary lighting function.

If the light intensity value is lower than the preset value and the auxiliary lighting function is started, the working lamp 150 is controlled to be turned on. If the auxiliary lighting function is turned off and the light intensity value is no matter what value, the working lamp 150 is controlled to be turned off.

Thus, when the operator turns on the auxiliary lighting function and detects that the light intensity value reaches the preset condition, the working lamp 150 is turned on for a predetermined time to provide sufficient illumination and time for the operator to complete the operation. In the process of gradually entering night, the light intensity value of the environment is gradually reduced, when the light intensity value is lower than the preset value, the working lamp 150 is turned on, the turning-on time is optimal, the power supply is saved, and the light can be used for illuminating an operator. The operator may also turn off the worklight 150 completely by turning off the auxiliary lighting function.

The operating light 150 is preferably turned on for a period of time ranging from: 10 s-200 s. Within the time length range, the operation work can be completely finished, and the time is more reasonable than the existing 5s time. In this way, the display screen 120 has the function of adjusting the time length when the work light 150 is turned on, and the time length when the work light 150 is turned on can be set according to the habit of an operator, so that the operation is more intelligent and convenient.

s11: the work machine 200 is powered on.

S12: the display screen 120 starts displaying, and the light sensor 110 starts detecting the light intensity value of the environment.

S13: and judging whether the light intensity value is lower than a preset value.

If the light intensity value is lower than the preset value, S14 is performed: a power-on command is sent to the power management module 140 via the display 120. If the light intensity value is not lower than the preset value, the loop continues to S13.

S15: it is determined whether the key panel 130 is open.

If the key panel 130 is turned on, an on command is sent to the power management module 140. If the key panel 130 is not turned on, no turn-on command is sent to the power management module 140.

After the power management module 140 receives the on command from the display 120 and the on command from the key panel 130, the process proceeds to S16: the power management module 140 controls the operation lamp 150 to be turned on.

If any one of the power management module 140 of the opening command sent by the display 120 and the opening command sent by the key panel 130 is not received, S16 is not performed, and S16 is not performed until both commands are received.

In the power-off process of the construction machine 200, please refer to fig. 5:

s21: the work machine 200 is powered off.

S22: it is determined whether the key panel 130 is open.

If the key panel 130 is not opened, the process is terminated. If the key panel 130 is opened, S23 is performed: and judging whether the light intensity value is lower than a preset value.

If the light intensity value is lower than the preset value, S24 is performed: a power-on command is sent to the power management module 140 via the display 120. If the light intensity value is not lower than the preset value, the loop continues to S23.

When the power management module 140 receives the turn-on command from the display screen 120, the process proceeds to S25: the power management module 140 controls the operation lamp 150 to be turned on.

S26: the operation lamp 150 is turned off after being turned on for a preset time period.

The preset time period can be set by the operator through the display 120.

The mechanical engineering that this embodiment provided beneficial effect:

1. the operator may turn on the key panel 130, the light sensor 110, the display screen 120, the power management module 140 and the work light 150 to process the standby state if necessary, and when the light sensor 110 detects that the light intensity value reaches the preset condition, the work light 150 is turned on for a predetermined time to provide sufficient illumination and time for the operator to complete the operation.

2. The operator may turn off the key panel 130 if the operator does not need to turn on the working light 150, so that the power management module 140 does not turn on the working light 150 regardless of the intensity of the environment.

3. The night auxiliary lighting system 100 also has the advantages of adjustable time, intellectualization and no conflict with the power failure of the whole vehicle, and CAN control the working time of the working lamp 150 after flameout through the display screen 120 by the CAN bus communication between the display screen 120 and the power management module 140, thereby completing auxiliary lighting.
