[0041] Through the drawing function, operations such as establishing the foundation, building rooms, adding doors and windows, adding furniture, and assigning materials are carried out to achieve the purpose of establishing an indoor model.

[0042] 2. Lighting fixture settings

[0043] A certain type of shelter selects the KHDJ-LED15-C621 type of lighting fixture manufactured by Shenyang Jinkehua Industrial Equipment Manufacturing Co., Ltd., with dimensions of 621mm * 180mm * 40mm (length * width * height). After the shelter is built, the lighting fixture model is imported.

[0044] 3. Calculation element settings

[0045] In the calculation element function module, calculation surfaces and calculation points can be set in the already built model, and at the same time, the illuminance parameters to be calculated can be selected, such as: unified glare rating (UGR), average illuminance, etc.

[0046] 1) Calculation surface settings

[0047] The seat platform and monitoring equipment are the main office equipment in the operation cabin. Calculation surfaces 1 - 10 are set on the upper, middle, and lower monitor screens and the desktop of the seat platform of the 3 seat platforms, and calculation surfaces 11 - 12 are set on the monitoring equipment screen and the keyboard operation surface; Calculation surface 13 is set in the middle aisle.

[0052] (2) Comfort value settings and result analysis

[0053] 1. Comfort value settings for operation cabin lighting

[0054] Since there are no standard regulations for the lighting part in GJB 6109-2007 General Specification for Military Shelter, considering that the layout and application of the shelter are similar to office lighting in building lighting, we referred to some standards in GB50034-2013 Standard for Lighting Design of Buildings, as well as the relevant requirements in GJB4000-2000 General Specification for Ships which is relatively close to the shelter environment.

[0055] The comfort value of lighting in the operation cabin is set with reference to the relevant requirements in GJB4000-2000 General Specification for Ships, and combined with the relevant regulations in GB50034-2013 Standard for Lighting Design of Buildings. The basic illuminance of general work surfaces such as the operation console surface and the computer control area is set to 300 lx, the uniformity is greater than 0.6, and the UGR (Unified Glare Rating) is less than 19.

[0056] 2. Setting of lighting comfort value in equipment cabin and link cabin

[0057] Considering that sufficient illuminance is required for maintenance in the equipment cabin and link cabin to enable maintenance personnel to work smoothly, based on the illuminance setting in the power distribution room in GB50038-2005, according to the requirements of the relevant regulations in GB50034-2013, the illuminance value of 150 lx on the surface of the power distribution equipment is increased by one level, from 150 lx to 200 lx, the illuminance uniformity should be greater than 0.6, and the UGR value is less than 19.

[0058] 3. Analysis of simulation results

[0059] Under the normal lighting scenario, a certain type of shelter lighting lamp is 15 W, the luminous efficiency in the working state is 120 lm / W, the luminous flux is 1800 lm, there are 6 lighting lamps in the operation cabin, 2 lighting lamps in the equipment cabin, and 2 lighting lamps in the link cabin.

[0060] Start the lighting simulation software to conduct simulation analysis on the illuminance distribution of each calculation surface and the UGR value of each calculation point.

[0061] Average illuminance calculation formula:

[0062] Eav=F*n*u*η / (A*K)

[0063] Among them, F is the luminous flux of the lamp

[0064] n is the number of lamps

[0065] u is the utilization factor

[0066] η is the lamp efficiency

[0067] A is the irradiation area

[0068] K is the maintenance factor

[0069] Unified Glare Rating calculation formula:

[0070]

[0071] Wherein, Lb is the background luminance

[0072] L is the luminous intensity of the light source in the direction of the observer's eyes

[0073] ω is the solid angle subtended by the glare source with respect to the eyes

[0074] P is the degree of deviation of the glare source from the line of sight
