[0039] The lighting quality detection device in the tunnel includes an external brightness detection device 1, an internal illumination detection device 2, a lighting quality monitoring system control host 3 and a background management center server 4; the external brightness detection device 1 and the internal illumination detection device 2 are both connected to the lighting quality monitoring system control host 3, and the lighting quality monitoring system control host 3 is used to calculate the theoretical demand value of the road surface lighting quality of each lighting section according to the brightness value measured by the external brightness detection device, and at the same time calculate the actual road surface lighting quality value of each lighting section according to the tunnel wall illumination value measured by the internal illumination detection device and the corresponding relationship, and compare the theoretical demand value of the road surface lighting quality of each lighting section with the actual road surface lighting quality value of each lighting section; the background management center server 4 is connected to the lighting quality monitoring system control host 3 and receives data fed back by the lighting quality monitoring system control host 3, and archives the fed back data in real time.

[0041] The calculation module 31 is used to calculate the theoretical required value of road surface lighting quality in each lighting section in the tunnel according to the outside brightness value measured in real time by the outside brightness detection device 1.

[0042] The corresponding module 32 is used to calculate the actual road surface lighting quality value of each lighting section according to the tunnel wall illumination value measured in real time by the tunnel illumination detection device 2 and the corresponding relationship.

[0043] The comparison module 33 is used to compare the received theoretical required values ​​of road lighting quality of each lighting section with the actual road lighting quality values ​​of each lighting section, and judge whether the lighting quality of each lighting section meets the standard at the current monitoring time, and send the results to the evaluation module 34.

[0047] Preferably, the brightness detection device outside the cave and the illumination detection device inside the cave both include brightness sensors for detecting brightness.

[0048] See also Figure 1 The method of using the tunnel lighting quality detection device specifically includes the following steps:

[0049] Step S10: determining the corresponding relationship between the road surface lighting quality value of each lighting section in the tunnel and the tunnel wall illumination value; the method is: according to different lighting ratios, respectively measure the actual road surface lighting quality value of each lighting section of the tunnel and the tunnel wall illumination value, and determine the corresponding relationship between the actual road surface lighting quality value of each lighting section of the tunnel and the tunnel wall illumination value, and the specific implementation steps are as follows:

[0050] Step 1): in each lighting section of the tunnel, an illumination detector is used to detect the average brightness value L of the road surface lighting and the wall illumination value LU of each lighting section of the tunnel, and the corresponding relationship between the average brightness L of the road surface and the wall illumination LU of each lighting section is determined;

[0051] Step 2): Adjust the opening percentage of the tunnel lighting fixtures, set 20 levels of 5%, 10%, 15%, 20%, 25%...100% respectively, measure the average brightness value L of the road surface lighting in each lighting section under each level, and record the tunnel wall illumination value LU measured by the illumination sensor of the corresponding lighting section (the illumination sensor belongs to the illumination detector);

[0052] Step 3): Calculate the average road surface brightness L05, L10, L15...L100 at different lamp opening percentages for each lighting section, and correspond them one by one with the measured tunnel wall illuminance values ​​LU05, LU10, LU15...LU100, to form a correspondence table between the tunnel wall illuminance values ​​and the average road surface lighting brightness values ​​of each lighting section (based on the obtained correspondence table between the tunnel wall illuminance values ​​and the average road surface brightness values, the actual road surface lighting quality value of the corresponding lighting section can be inferred when the tunnel wall illuminance values ​​of each lighting section are detected).

[0053] Step S20: measuring and obtaining the current ambient brightness value outside the tunnel through the external brightness detection device 1 arranged outside the tunnel;

[0054] Step S30: The calculation module 31 calculates the theoretical required value of road surface lighting quality in each lighting section of the tunnel according to the ambient brightness value outside the tunnel (the relationship between the ambient brightness value outside the tunnel and the theoretical required value of road surface lighting quality in each lighting section refers to "JTG / TD70 / 2-01-2014 Highway Tunnel Lighting Design Regulations");

[0055] Step S40: measuring and obtaining the illumination value on the tunnel wall of each lighting section of the tunnel by the in-tunnel illumination detection device 2;

[0056] Step S50: the corresponding module 32 calculates the actual road surface lighting quality value of each lighting section in the tunnel according to the corresponding relationship obtained in step S10 and the tunnel wall illumination value obtained in step S40;

[0057] The corresponding module receives the illumination value of the tunnel wall of each lighting section detected by the illumination detection device in the tunnel, and determines which interval (0-5%, 5%-10%...95%-100%) the illumination value is in in the corresponding relationship table through the CPU processor in the lighting quality monitoring system control host. After determining the interval, the corresponding interpolation formula is selected to calculate the road surface brightness value according to the tunnel wall illumination value, and the brightness value is used as the actual road surface lighting quality value of the lighting section. (The calculation module, the corresponding module, the comparison module, the evaluation module and the sending module realize the corresponding functions through the CPU processor in the control host)

[0058] Step S60: Compare the theoretical required value of road lighting quality of each lighting section obtained in step S30 with the actual road lighting quality value of each lighting section obtained in step S50 through the comparison module 33; determine whether the lighting quality of each lighting section meets the standard at the current monitoring time, and send the result to the evaluation module 34;

[0059] Step S70: The evaluation module 34 counts the number of times that the actual road lighting quality value is greater than the theoretical lighting quality requirement value and the total number of detections during the evaluation period, and calculates the lighting quality compliance ratio as the lighting quality compliance rate of the lighting section;

[0060] Finally, the sending module 35 sends the ambient brightness value outside the tunnel, the actual road lighting quality value inside each lighting section, and the lighting quality compliance status of each lighting section to the background management center server 4 through the network, so that the management personnel can understand the lighting conditions in the tunnel.

[0061] The technical solution of this embodiment is specifically:

[0062] The tunnel lighting quality detection device of the present invention is installed as required, the brightness detection device outside the tunnel is set at the tunnel entrance as required, and the illumination detection device inside the tunnel needs to be set in each lighting section as required; after the device is set up, the lighting quality in the tunnel can be detected according to the detection method of the present invention.

[0063] Taking a highway tunnel as an example, according to the "Highway Tunnel Lighting Design Specifications" (JTG / T D70 / 2-01-2014) standard, the lighting section is divided into 7 lighting sections (highway), namely entrance section 1, entrance section 2, transition section 1, transition section 2, middle section, exit section 1 and exit section 2. The length of each lighting section is calculated according to the standard.

[0064] The average brightness value L of the road surface in each section of the tunnel and the wall illumination value LU are detected by an illumination detector, and the corresponding relationship between the average brightness value L and the wall illumination value LU is determined; then the wall illumination value measured in real time by the illumination detection device in the tunnel is used to reflect the average brightness value L of the tunnel road surface according to the corresponding relationship, which is used as the actual lighting brightness value of each lighting section of the tunnel. The specific implementation is as follows:

[0065] 1) Select a section of the road surface in each of the seven lighting sections of the tunnel and divide it equally in the longitudinal and transverse directions. The number of dividing lines is determined according to the requirements of detection accuracy. The division rule is: the length taken along the road direction must be a cycle of the lighting fixture arrangement, and the transverse direction of the road must include all lanes; Figure 3 As shown, m equal-dividing lines are set along the length taken in the road direction to divide the length in the road direction into m-1 grids, and n equal-dividing lines are set in the transverse direction of the road to divide the transverse direction of the road into n-1 grids, where m and n are both natural numbers greater than 1;

[0066] 2) Adjust the opening percentage of the tunnel lighting fixtures to 5%, 10%, 15%, 20%...100% respectively, which is divided into 20 levels of adjustment. Measure the brightness value at the intersection of the longitudinal and transverse bisectors on the road surface selected by each lighting section when adjusted to each level (i.e., the measuring point) (the measured brightness value can be converted into the average road surface brightness according to the conversion coefficient in the "Highway Tunnel Lighting Design Rules"), and record the current wall illumination value on the tunnel wall measured by the illumination sensor, and record a total of 140 sets of data.

[0067] 3) Calculate the average road surface brightness L05, L10, L15...L100 of each lighting section when the lamps are turned on at different percentages, and correspond them one by one with the tunnel wall illumination values ​​LU05, LU10, LU15...LU100 on the tunnel wall measured by the illumination sensor, to form Table 1, the correspondence relationship between the tunnel wall illumination and the road surface brightness of each lighting section.

[0069]

[0070]

[0071] After the corresponding relationship table is obtained, the detection device and method of the present invention can be used to achieve the purpose of real-time detection of the lighting quality in the tunnel and statistics on the proportion of lighting quality reaching the standard.

[0072] Applying the technical solution of the present invention has the following effects:

[0073] The detection method and device of the present invention can realize real-time monitoring of the lighting quality of each lighting section after the tunnel is opened to traffic, and evaluate the lighting quality compliance rate of each lighting section, so that the management unit can understand in real time whether the tunnel lighting quality meets the standard requirements, and provide a basis for the tunnel lighting system control strategy; at the same time, the device can automatically archive the monitoring data of the tunnel lighting quality in real time for the purpose of reviewing and providing evidence after a traffic incident occurs.

[0074] The corresponding relationship in the tunnel is measured once before the tunnel is opened to traffic, and then the lighting quality in the tunnel can be detected according to the corresponding relationship and the real-time measured tunnel wall illumination value to obtain the actual road surface lighting quality value of each lighting section; and the actual road surface lighting quality value of each lighting section is compared with the theoretical demand value of the road surface lighting quality of each lighting section to obtain the lighting quality situation in the tunnel, which can help management personnel to adjust the opening ratio of lamps in the tunnel in real time; the detection method of the present invention is simple and practical, and a lifelong detection of the lighting quality of the tunnel can be achieved by measuring the corresponding relationship in the tunnel once.
