Su Wei's lips twitched slightly, but he quickly suppressed it.
He looked down and typed.
"Tomorrow won't work. I need to go to Old Hope's place to pick up some things; the brown bear specimen should be finished by now."
Send it out.
Emily's reply was a few seconds slower this time.
"Oh."
One word.
Su Wei typed another line.
How about the day after tomorrow?
The reply was quick this time.
"The day after tomorrow is fine too. Let's go with the day after tomorrow then."
His tone returned to normal, and he even added an "ah" sound.
Su Wei could imagine what she looked like.
He was lying in bed holding his phone, first pouting, then letting go when he saw the words "the day after tomorrow".
He added a sentence.
"Shall we bring Cotton Candy?"
"Of course I'll bring it!"
This time it was a reply that came instantly, followed by an exclamation mark.
"It'll be so much fun playing in the snow!"
Su Wei placed his phone on the table.
The light from the screen reflected off the windowpane, refracting into a small white patch within the frost.
The Cotton Candy in front of the fireplace rolled over, its tail sliding down from its nose and draping over the edge of the blanket.
Su Wei turned off his phone.
We'll talk about what happens the day after tomorrow.
Tomorrow, there's something even more important to do.
However, we will continue to complete the project.
The Woodland Base and the cliff framework of the sky area on the second floor have already taken shape.
However, the entire exhibition hall is still missing the final step.
electricity.
To be precise, it's a control system.
Su Wei stood in the center of the first-floor lobby and looked up, scanning the area.
From the ceiling to the walls, to the load-bearing columns and the entrances to each exhibition area, everything is interwoven with a dense network of conduits and pre-embedded slots.
These include PVC pipes, flexible metal conduits, as well as shielded cables and signal cables.
In addition, there are full-spectrum light sets on the second floor.
The first floor features a water mist spray system in the valley, and the tidal pool's heating rods and wave-making pumps are controlled by frequency converters.
And temperature and humidity sensors are located throughout the building.
The nerve endings of everything eventually converge into that 1.2-meter-high industrial-grade electrical distribution box in the basement.
If any wire is connected incorrectly, it may cause a short circuit and trip the circuit breaker, or even burn out the equipment.
An electrical malfunction next to the 5,000-liter seawater pool could have had unimaginable consequences.
Su Wei crouched down and lifted the maintenance cover on the first floor.
The cables in the cable trays were stacked together, in red, blue, yellow, and green, and of varying thicknesses.
[ Mechanical Repair LV2 Activated.]
The perspective has changed.
The cables that were originally tangled together were dismantled one by one in his perception.
The route, specifications, and corresponding terminal equipment of each cable are clearly displayed.
The 16 square millimeter copper core wire starts from the main circuit of the distribution box and splits into three circuits.
The first route leads to the river valley area on the first floor, supplying circulating pumps and chiller units.
The second route goes through the tidal pool area, which has a heavier load, requiring the dragging of wave generators and heating systems.
The third route goes up to the second floor and is specifically for the lighting fixtures.
The signal line is routed through a separate conduit.
Devices such as temperature and humidity sensors, water level probes, and salinity meters must maintain sufficient distance from high-voltage power cables.
Otherwise, electromagnetic interference will distort all the data.
Su Wei straightened up and nodded at Matt.
"I'll start installing from the second floor downwards. You and your team will tighten all the remaining conduit clips on the first floor."
Matt nodded, said nothing more, and turned to call out to the workers.
Su Wei carried his toolbox upstairs to the second floor.
Sky area.
The four-meter-high miniature cliff face casts a deep shadow under the cold light source.
But this shadow is dead; there is no change in light or shadow, nor is there a transition between dawn and dusk.
At this moment, the cliff face is just a gray wall.
The three sets of full-spectrum matrix lights arrived a week ago.
They have aluminum alloy casings, and each set weighs over thirty kilograms.
The light fixtures were disassembled into six modules and stacked in a wooden crate in the corner.
Su Wei set up a simple pulley.
The steel wire rope passes through the pre-installed hanging rings in the ceiling, with one end hanging on the mounting bracket of the light fixture and the other end wound around a hand-cranked winch.
He operated the winch alone, and the steel cable immediately tightened, causing the light assembly to slowly rise.
The 30-kilogram aluminum alloy frame swayed slightly in the air.
Su Wei controlled the winch to move extremely slowly, pausing for two seconds after each revolution to confirm the horizontal orientation of the light assembly.
After the lights were in place, Su Wei climbed up the scaffolding.
He used four M12 stainless steel expansion bolts to secure the mounting bracket to the load-bearing steel beam in the ceiling.
After tightening the wrench to the last half turn, he patted the frame with his palm, but it didn't budge.
Group 2, Group 3.
Repeat three times, hanging up all three sets of lights.
wiring.
Su Wei opened the junction box on the back of the light assembly.
Three wires: live wire, neutral wire, and ground wire, plus a five-core signal control wire.
The signal cable is crucial.
It is connected to the DMX module of the central control console and is responsible for receiving instructions from the dawn/dusk simulation program.
The color temperature ranges from warm yellow to cool white, and the brightness ranges from 0 to 100%, all controlled by this single line.
The Su Wei wire stripper gripped the outer sheath of the signal wire, rotated it, and pulled out the copper core.
Five thin lines, each corresponding to one channel.
He pressed the terminal blocks one by one and tightened them with a screwdriver.
With his Mechanical Repair skills, his fingers are unusually steady.
The stripping depth is controlled at the millimeter level, without damaging the copper core or leaving burrs.
Even the torque of each screw on the terminal block is almost exactly the same.
After connecting the three sets of lights, Su Wei used a multimeter to test the continuity of each one.
The resistance value is normal.
The insulation value is normal.
He jumped down from the scaffolding and walked into the wooded area.
The lighting setups in the forest area differ from those in the sky area.
