Example 1
Referring to fig. 4, this embodiment shows a schematic flow chart of a pipe to be tested according to an embodiment of the present invention. The pipelines to be detected comprise a vertical shaft pipeline and a transverse pipeline. As shown in fig. 4, where the vertical shaft tunnel is connected to the transverse tunnel, ambient light is taken into the transverse tunnel through the vertical shaft tunnel, dividing the transverse tunnel into regions that can receive ambient light and regions that cannot receive ambient light.
Corresponding to the pipe structure shown in fig. 4, fig. 1 shows a dimming method of the pipe detection apparatus including:
s10: and determining the illumination distance of ambient light in the transverse pipeline according to the diameter of the transverse pipeline, the depth of the vertical shaft pipeline and the diameter of the vertical shaft pipeline, wherein the area corresponding to the illumination distance is used as a first working area, and other areas of the transverse pipeline are used as second working areas.
The illumination distance is calculated by the formula S ═ D (L/(H-D)), where D is the transverse duct diameter, L is the vertical duct diameter, H is the vertical duct depth, and S is the illumination distance.
Exemplarily, when the transverse pipe diameter D is 600mm, the shaft pipe diameter L is 600mm, and the shaft pipe depth H is 2000mm, the illumination distance S is calculated to be about 257mm by using the above formula. It can be understood that when the pipeline detection device travels towards the inside of the transverse pipeline at the inlet of the transverse pipeline, the ambient light can be acquired by the front 257mm, and the ambient light gradually weakens as the pipeline detection device travels away from the inlet.
S20: judging the working state of the pipeline detection equipment according to the working area and the advancing direction of the pipeline detection equipment, wherein the working state comprises the following steps: the pipe detecting device is in the first working area and the traveling direction is a first working state heading from the first working area to the second working area, the pipe detecting device is in a second working state of the second working area, and the pipe detecting device is in the first working area and the traveling direction is a third working state heading from the second working area to the first working area.
It can be understood that after the pipeline detection equipment enters the transverse pipeline through the vertical shaft pipeline, the pipeline detection equipment gradually moves away from an inlet of the transverse pipeline and sequentially goes through a first working state and a second working state; and when the pipeline detection equipment returns to the inlet of the transverse pipeline, the pipeline detection equipment sequentially goes through a second working state and a third working state.
S30: and determining a standard illumination value through the diameter of the transverse pipeline, and executing a corresponding regulation and control scheme according to the standard illumination value and the working state so as to adjust a dimming device of the pipeline detection equipment.
It will be appreciated that the larger the diameter of the transverse conduit, the larger the standard illumination value should be in order for the conduit to acquire the appropriate detection illumination; when the pipeline detection equipment detects the pipeline, the pipeline detection equipment is sequentially in three working states, and corresponding regulation and control schemes are designed for different working states so as to adjust the dimming device of the pipeline detection equipment.
Illustratively, the diameter of the transverse pipeline is 600mm, and the corresponding standard illumination value can be 800Lx, and the illumination value at this time can enable the detection picture of the pipeline detection device to be maintained in a clear state.
Further, as shown in fig. 2, when the pipeline inspection device is in the first working state, that is, the pipeline inspection device is in the first working area and the traveling direction is away from the transverse pipeline entrance, the corresponding control scheme includes the following steps:
s311: and acquiring an illumination value at the inlet of the vertical shaft pipeline as an initial environment illumination value.
And detecting the external illumination value of the pipeline, and recording the external illumination value into a detection system for subsequent steps.
S312: and determining a basic distance required to be traveled by the pipeline detection equipment according to the illumination distance, the standard illumination value and the initial environment illumination value, and weakening the environment illumination value in the transverse pipeline to be equal to the standard illumination value when the pipeline detection equipment reaches the basic distance.
It can be understood that the ambient light in the transverse pipeline is gradually attenuated as the pipeline detection device moves away from the inlet of the transverse pipeline, the base distance that the pipeline detection device needs to travel needs to be determined according to the illumination distance, the standard illumination value and the initial ambient illumination value, and the ambient illumination value in the transverse pipeline is weakened to the standard illumination value when the pipeline detection device reaches the base distance.
Further, the base distance is calculated by the following formula:
Lz/Lh＝(S-S0) (S), wherein Lz is the standard illumination value, Lh is the initial ambient illumination value, S is the illumination distance, S0Is the base distance.
Exemplarily, when the illumination distance S is 257mm, the standard illumination value Lz is 800Lx, the initial ambient illumination value Lh at the entrance is 1200Lx, and the formula Lz/Lh is (S-S) according to0) The calculated base distance/S is approximately 86 mm.
S313: and recording a first running time, wherein the first running time is counted after the pipeline detection device runs away from the basic distance.
It can be understood that when the pipeline detection device is located in the basic distance range, the ambient light in the transverse pipeline is not lower than the standard illumination value, and the dimming device carried by the pipeline detection device does not need to be started. However, when the pipeline detection device is driven away from the basic distance range, the ambient light in the transverse pipeline is continuously attenuated and will be lower than the standard illumination value, and at this time, the timing is started after the pipeline detection device is driven away from the basic distance, and the recorded time is used as the first driving time for the subsequent steps.
S314: and calculating a first illumination adjusting value according to the standard illumination value, the initial environment illumination value, the basic distance, the illumination distance, the running speed and the first running time, starting a dimming device carried by the pipeline detection equipment, and adjusting the illumination intensity of the dimming device to the first illumination adjusting value.
Exemplarily, the initial ambient light value Lh at the entrance obtained at the entrance of the shaft pipeline is 1200Lx, the ambient light gradually weakens as the pipeline detection device drives away from the entrance of the transverse pipeline, and when the ambient light weakens to the standard light value Lz, which is 800Lx, the dimming device carried by the pipeline detection device is started, and the light intensity of the dimming device is adjusted to the first light adjustment value.
Further, the first illumination adjustment value is calculated by the following formula:
Lab1＝Lz-Lh*((S-S0-v*t1) S), wherein Lz is the standard illumination value, Lh is the initial ambient illumination value, S is the illumination distance, S)0Is the base distance, v is the driving speed, t1Is the first travel time, Lab1Is the first illumination adjustment value.
Exemplarily, the running speed v of the pipeline detecting device may be 27.5mm/s and the first running time t12S, initial ambient light value Lh 1200Lx, standard light value Lz 800Lx, base distance S 0When the illumination distance S is 257mm, the formula Lab is used1＝Lz-Lh*((S-S0-v*t1) /S) can calculate a first lighting regulation Lab when the first travel time is equal to 2S1Approximately equals to 256Lx, then a dimming device carried by the pipeline detection equipment is started at the moment, and the illumination intensity of the dimming device is adjusted to the first illumination adjustment value 256 Lx.
It can be understood that when the first travel time t is14s, the other parameters of the above formula remain unchanged, according to the formula Lab1＝Lz-Lh*((S-S0-v*t1) /S) can calculate a first illumination control value Lab1Approximately equal to 514Lx, when the illumination intensity of the dimming device should be adjusted to 514 Lx; when the first travel time t1＝6s，The other parameters of the above formula are kept constant according to the formula Lab1＝Lz-Lh*((S-S0-v*t1) /S) can calculate a first illumination control value Lab1Approximately equal to 687Lx, the light intensity of the light adjusting device is adjusted to 687Lx automatically.
It should be understood that when the pipeline detection device exits the first area, the dimming device carried by the pipeline detection device adjusts the illumination intensity of the dimming device to the standard illumination value 800Lx, and in the second working area, the detection work is performed while maintaining the standard illumination value 800 Lx.
Further, as shown in fig. 3, when the pipeline inspection device is in the third working state, that is, the pipeline inspection device is in the first working area and the traveling direction is returning to the inlet, the corresponding control scheme includes the following steps:
S321: and acquiring an illumination value at the inlet of the vertical shaft pipeline as an initial environment illumination value.
And detecting the outside illumination value of the pipeline, and recording the outside illumination value into the system for subsequent steps.
S322: and recording a second running time, wherein the second running time is counted from the time when the pipeline detection device starts to execute the third working state.
It can be understood that when the pipeline detection device works in a pipeline area which cannot receive ambient light, the dimming device carried by the pipeline detection device adjusts the illumination intensity of the dimming device to the standard illumination value of 800Lx, and performs detection work, and when the pipeline detection device returns to the inlet of the transverse pipeline, the illumination intensity of the dimming device needs to be gradually weakened when the pipeline detection device enters the illumination distance range, so that the illumination intensity in the transverse pipeline keeps the standard illumination value. Therefore, it is necessary to start timing from when the pipeline inspecting apparatus starts to perform the third operating state, and the timing is taken as a second travel time for the subsequent step.
S323: and calculating a second illumination adjusting value according to the initial environment illumination value, the standard illumination value, the illumination distance, the running speed and the second running time, and adjusting the illumination intensity of a dimming device of the pipeline detection equipment to the second illumination adjusting value.
Further, the second illumination adjustment value is calculated by the following formula:
Lab2＝Lz-Lh*((v*t2) S), wherein Lh is the initial ambient illumination value, Lz is the standard illumination value, v is the travel speed, S is the illumination distance, t2Is the second travel time, Lab2Is the second illumination adjustment value.
Exemplarily, in the third operating state, the ambient light in the transverse duct changes from weak to strong, the illumination distance is kept constant, S is 257mm, the initial ambient light value Lh at the inlet is 1200Lx, the standard light value Lz is 800Lx, the driving speed v of the duct detection device may be 27.5mm/S, and the second driving time t2When 2s, according to the formula Lab2＝Lz-Lh*((v*t2) /S) can calculate the second illumination adjustment Lab2Approximately 543Lx, then the light intensity of the light adjusting device carried by the pipeline detection device is automatically adjusted to 687Lx, and at this time, the light intensity of the light adjusting device carried by the pipeline detection device is integrated with the ambient light so as to maintain the standard light intensity 800Lx in the pipeline.
It will be understood that when t is2When the time is 4s, calculating a second illumination adjustment value Lab2About 286 Lx; when t is2When 6s, calculating a second illumination adjustment value Lab2About 30 Lx.
It should be understood that when the pipeline detection device is driven into the basic distance as shown in fig. 4, the dimming device carried by the pipeline detection device is already turned off, the dimming device is not required to compensate illumination, and the ambient light can maintain the standard illumination intensity in the pipeline to be not lower than 800 Lx.
