4. M*n configuration and parameters

1. Fire extinguishing control cabinet

(1) Fire extinguishing controller

The fire extinguishing controller uses a single-chip microcomputer as the m*n controller to detect the status of smoke detectors, water flow indicators, signal butterfly valves, and pressure switches, and outputs alarms, sound and light alarms, and starts the sprinkler pump in the automatic state. The host computer monitoring function can be realized through the serial port and software, and the local control and linkage control switching function can be realized at the same time.

(2) Fire extinguishing control cabinet

The fire extinguishing control cabinet is composed of a power switch, a voltage source indicator, a status indicator light (smoke detector, water flow indicator, signal butterfly valve, pressure switch), an audible and visual alarm, a manual control device and other parts. It can complete the functions of the sprinkler fire extinguishing system, such as power control, status indication, fire alarm, automatic fire extinguishing, and manual fire extinguishing control. It also has a linkage control interface and can accept linkage control signals from other fire alarm systems.

2. Sprinkler fire extinguishing system model

The m*n components of the model, such as the frame and water tank, are all made of st*nless steel to ensure that they will not rust or age, and can simulate the sprinkler fire extinguishing system of a two-story building. The model system is m*nly composed of typical water sprinkler fire extinguishing equipment such as sprinkler pumps, *r pressure tanks, wet alarm valves, hydraulic alarms, timers, pressure switches, water flow indicators, closed nozzles, test valves, fire detectors, and fire alarms, which can vividly simulate the typical structure of a water fire extinguishing system in a building.

2) Air pressure tank: 1 unit, volume 50 liters

3) Wet alarm valve: Quantity: 1 unit Diameter: φ100mm Rated working pressure: 1.2MPa

4) Glass ball nozzles: at least 6 pieces, 68℃ temperature level

5) Water flow indicator: at least 2, sensitivity 15L-37.5L/min

6) Smoke detector: 2

Virtual simulation software for electrical installation of buildings and intelligent buildings (fire protection module)

Based on Unity3D design, users can choose different sizes of interactive interfaces according to their computer configurations, and can choose six levels of image quality. The models in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, as follows:
