1. Determine the theme and goal: define the theme and goal of the fire warning portrait, and determine the content and key points to be expressed in the portrait. Collection of data and materials: Collect data and materials related to fire early warning through Internet, library and news media, including the composition, working principle and alarm mode of fire early warning system.
2. Sketch: On the basis of collecting enough materials, start sketching portraits. The sketch should include all components of the fire alarm system, such as sensors, controllers, alarms, etc. , and their connection. At the same time, we should also consider how to show the characteristics and working state of the fire alarm system through pictures.
3. Drawing: On the basis of sketching, we began to draw with strokes. In the process of drawing, we should pay attention to depicting the details and characteristics of each component, and at the same time pay attention to the balance and coordination of the overall picture. If you need to add a text description, you can add concise text at the corner or bottom of the portrait.
