Based on unity3d design, users can choose different sizes of interactive interfaces according to their computer configuration, and can choose six levels of image quality. The model in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, the contents are as follows:
A. Wet alarm system
1. System overview: Overview of wet alarm system
2. Equipment recognition: It is equipped with the best viewing angle, equipment det*ls (displaying the introduction or parameters of the equipment), exercises (built-in 6 multiple-choice questions, with prompts for correct and wrong choices), and schematic diagrams (you can enter the equipment from the schematic diagram). The equipment includes: sprinklers, water flow indicators, signal butterfly valves, exhaust valves, fire alarm controls, high-pressure gauges, high-level water tanks, Wia control cabinets, pressure-stabilizing tanks, flow switches, terminal water testing devices, dr*nage facilities, water pump connectors, hydraulic alarms, time delays, wet alarms, butterfly valves, check valves, fire pumps, safety pressure-stabilizing valves, and fire water tanks.
3. Principle display: Display the working principle of the wet alarm system, 3D animation demonstration, and semi-transparent 3D models, so that the internal water flow can be seen. Equipped with practice module (built-in 4 multiple-choice questions, with prompts for correct and wrong choices)
4. Design layout: There are multiple-choice questions and calculation questions, each of which is scored, and the correct answer and score will be displayed after submission
B. Gas fire extinguishing system
1. System overview: Overview of gas fire extinguishing system
2. Equipment cognition: It is equipped with the best viewing angle, equipment det*ls (displaying the introduction or parameters of the equipment), practice (built-in 8 multiple-choice questions, with prompts for correct and wrong choices), schematic diagram (you can enter the equipment from the schematic diagram).
