The total power of the loop represents the total power consumed by the illumination line tube, the loss coefficient represents the loss condition of the illumination line tube under the power-on condition, and the power factor of the light source refers to the cosine of the phase difference between the voltage and the current when the alternating current is applied to the light source in the circuit of the illumination line tube. The lower the power factor of the light source is, the larger the reactive power of the lighting line tube loop for alternating magnetic field conversion is, and the lower the utilization rate of the light source in the lighting line tube loop is, the larger the power supply loss of the lighting line tube loop is. Similarly, the line power factor is the power factor of the illumination conduit in the illumination conduit loop. The cross-sectional area of the core wire is the area of the cross section, perpendicular to the axial direction of the illumination wire pipe, of the core wire wrapped by the illumination wire pipe.

Figure BDA0002663755730000111
wherein, IC1Loop current of linear load, IC2Is the loop current of the nonlinear load.
It will be appreciated that the connection device includes a light source, which may be a tungsten halogen lamp when the light source is a linear load. When the light source is a non-linear load, the light source may be a gas discharge lamp. A linear load refers to a load whose load impedance parameter (Z) is constant when a variable sinusoidal voltage is applied. The nonlinear load is a load containing a rectifying device, the voltage and the current are not in a linear relation in the lighting line tube loop, and the relation between the voltage and the current is changed frequently in the input and operation processes of the load.
Step S213: the loop voltage drop is calculated based on the loop current as well as the line power factor, core cross-sectional area, and loop length.
It is to be understood that the loop voltage drop represents a voltage variation value in the lighting conduit loop, and as an embodiment, the loop voltage drop may be calculated by a loop voltage drop calculation formula, which includes:

Step S214: determining that the loop voltage drop is less than or equal to the allowed voltage offset value.
It is understood that the loop voltage drop calculated in step S213 is compared with the allowable voltage offset value, and when the loop voltage drop is less than or equal to the allowable voltage offset value, the minimum pipe diameter is determined. When the loop voltage drop is larger than the allowable voltage offset value, modifying the electrical relevant parameters of the lighting conduit, wherein the electrical relevant parameters comprise the total loop power, the loss coefficient, the light source power factor, the line power factor, the core wire section area and/or the loop length of the lighting conduit, recalculating the loop load according to the step S211, calculating the loop current according to the step S212, and calculating the loop voltage drop according to the step S213 until the loop voltage drop calculated according to the step S213 is smaller than or equal to the allowable voltage offset value.
It can be understood that the allowable voltage offset value refers to an allowable deviation of the power supply voltage of the power receiving end of the user under normal operation conditions of the power system, and the allowable voltage offset value is determined by the performance of the electrical appliance. The allowed voltage offset value in the illumination conduit is set according to the specifics of the light source in the illumination conduit loop.
Step S22: the minimum pipe diameter of the illumination pipe is determined based on the electrical correlation parameters.
It can be understood that the electrical related parameters include the number of the lighting tubes and the code of the lighting tubes, and the minimum tube diameter of the corresponding lighting tube is found according to the section of the core wire, the number of the tubes and the code of the lighting tubes in the manual of industrial and civil power supply and distribution design.
Step S23: and updating the original lighting tube model based on the minimum tube diameter.
It can be appreciated that if the minimum pipe diameter found is different from the pipe diameter parameter in the original illumination tube model, the pipe diameter in the original illumination tube model is replaced with the minimum pipe diameter found to update the pipe diameter parameter in the original illumination tube model. And when the searched minimum pipe diameter is the same as the pipe diameter parameter in the original illumination pipe model, keeping the pipe diameter parameter in the original illumination pipe model unchanged, wherein the pipe diameter parameter refers to the outer diameter of the illumination pipe.
Referring to fig. 3, fig. 3 is a flowchart of a step of building an original illumination tube model according to an embodiment of the present application. Before step S20, the illumination conduit modeling method further includes step S10, and step S10 includes the following sub-steps:
step S101: and acquiring the building parameters of the building where the lighting line tube is located.
It can be understood that the building parameters include building elevation information, wiring manner, depth of burial, lighting conduit pipe diameter, connecting equipment position and connecting equipment attributes. The building elevation information is divided into three types of building height, relative elevation and absolute elevation, wherein the building height refers to the height from the outdoor design ground of the building to a certain plane at the top of the building. The relative elevation is considered to be set, and the height of the first floor ground in the building is positioned to be a positive and negative zero starting point of the relative elevation. The absolute elevation is a national uniform standard, and a positive and negative zero starting point of the absolute elevation is positioned by the offshore plane near the yellow sea of the Qingdao. The building elevation information in the present application includes the floor upper surface elevation and the ceiling lower surface elevation, and the floor upper surface elevation and the ceiling lower surface elevation may determine the structure of the building by using the three elevation modes.
The wiring modes comprise ceiling wiring, floor wiring, wall wiring and the like, wherein the ceiling wiring is suitable for the situation that the connecting equipment for power utilization in the lighting line pipe loop is arranged on the ceiling and the wall, the floor wiring is suitable for the situation that the connecting equipment for power utilization in the lighting line pipe loop is arranged on the floor and the wall, and the wall wiring is suitable for the situation that the connecting equipment for power utilization in the lighting line pipe loop is arranged on the wall.

step S1021: and determining the wire inlet mode of the connecting equipment on the lighting wire pipe based on the installation mode.
It can be understood that different mounting manners correspond to different wire inlet manners of the connecting equipment on the lighting conduit. For example, for a wall-mounted installation, the direction of the incoming line of the connecting device is parallel to the ground and perpendicular to the back of the connecting device, the incoming line going into the wall. For the ceiling-mounted installation, the connection device is fed in a direction perpendicular to the ground and upwards towards the floor. In different installation modes, the incoming line direction of the connecting equipment is the wall or the floor on which the connecting equipment is fast supported.

It will be understood that the portion of the trace that extends from the connection device to the buried depth is referred to as the device access segment trace. The spatial position of the routing of the access section of the device is calculated according to different installation modes, for example, for a wall-mounted installation mode, the wire incoming direction of the connecting device is parallel to the ground and perpendicular to the back surface of the connecting device to lead the wire into the wall, and the spatial position of the routing which extends out from the connecting device and is parallel to the ground and perpendicular to the back surface of the connecting device to lead the wire into the wall is obtained, that is, the spatial position of the routing is obtained according to the wire incoming direction, the buried depth and the floor elevation information of the routing.
