6. Dimensions: 1400×500×1700mm, the appearance is a st*nless steel movable bracket with double brake wheels.
7. Virtual simulation software for electrical installation of building and intelligent building Designed based on unity3d, users can choose different sizes of interactive interface according to 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, as follows: A. Wet alarm system 1. System overview: Overview of wet alarm system 2. Equipment recognition: It has 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), schematic diagram (you can enter the equipment from the schematic diagram). The equipment includes: sprinkler, water flow indicator, signal butterfly valve, exhaust valve, fire alarm control, high pressure gauge, high-level water tank, Wia control cabinet, pressure regulating tank, flow switch, end water test device, dr*nage facilities, water pump connector, hydraulic alarm, delay, wet alarm, butterfly valve, check valve, fire pump, safety pressure regulating valve, fire water tank. 3. Principle display: Display the working principle of the wet alarm system, 3D animation demonstration, 3D model is semi-transparent, and the internal water flow can be seen. Equipped with exercise module (4 multiple-choice questions are built-in, and there are 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 are displayed after submission B. Gas fire extinguishing system 1. System overview: Overview of gas fire extinguishing system 2. Equipment recognition: There are optimal viewing angles, equipment det*ls (displaying the introduction or parameters of the equipment), exercises (8 built-in multiple-choice questions, and there are prompts for correct and wrong choices), and schematic diagrams (you can enter the equipment from the schematic diagram). The equipment includes: nozzles, HFC-227 storage bottles, bottle head valves, heptafluoropropane check valves, high-pressure hoses, gas check valves, safety valves, weighing alarms, electromagnetic starters, selection valves, smoke alarms, and fire alarm controllers. 3. Principle display: Display the working principle of the gas fire extinguishing system, 3D animation demonstrations, and 3D models are semi-transparent, and the internal gas can be seen. Equipped with practice module (3 multiple-choice questions built-in, with prompts for correct and incorrect choices) 4. Design layout: There are 6 multiple-choice questions, each with a score. The correct answer and score will be displayed after submission. C. Escape drill: Teaching is carried out in the form of fun games. Escape from the burning room within a limited time. Wrong choices will directly enter the score interface. Experimental purpose: Suitable for teaching majors such as refrigeration, *r conditioning, food freezing, and home appliances . The compressor, evaporator, and condenser in the system use transparent pressure-resistant glass as the shell, which can directly observe the evaporation and condensation of the refrigerant, and observe the refrigeration effect through the changes in the inlet and outlet water temperatures. M*n configuration: compressor, coil evaporator, and coil condenser with transparent pressure-resistant glass as the shell. Circulating water pump, glass rotor flowmeter, regulating valve group, PVC board cooling water tank; the test system consists of 8-way universal signal input LCD display patrol meter, PT100 thermocouple; there is a workbench that can be moved at any time.
