What can be used for design and drawing when drawing engineering drawings of integrated wiring system

Engineering drawings generally use AutoCAD, Zhongwang CAD, Haochen CAD, Caxa, UG and other software. Among them, the most widely used is Aut.oCAD, mainly used for two-dimensional drawing, detailed drawing and design documents, has now become an internationally popular drawing tool.

Let me recommend one to you. There is a tool called visio in office2003, which is used for drawing vector diagrams. It is often used to draw two-dimensional floor plans, such as layout diagrams, top views, floor plans, connection diagrams, geolocation diagrams and flowcharts.

Connect the vertical trunk cable to the horizontal wiring subsystem of each floor. The equipment room subsystem connects various public equipment (such as computer hosts, digital program-controlled switches, various control systems, network interconnection equipment) to the main wiring rack.

Draw a comprehensive wiring diagram with visio: open the network diagram; on the "View" menu, click "Shape Data Window"; click the shape you want to add data; in the "Shape Data" window, select a data domain, and then type data for the domain; to move to the next attribute in the list, please Press the Enter key.

May I ask how to wire the joint vertical fire water cannon (second generation)?

1. Ensure the integrity of the fire alarm system. Note: All control and signal cables in this system should use twisted pair shielded cables. This cable is a weak current cable and cannot be laid together with the solenoid valve power line. When laying with a wire groove, a separate wire groove must be used.

2. FromThe water cannon needs to put a 6-core cable and a 2-core video cable to the control box. From the central control room to the control box, a 6-core cable should be laid (2-core power cable 220v, 2-core signal cable, 2-core 24V power cable, and some controllers are 220v). That should be all.

3. The second-generation intelligent fire water cannon of Lianzong Fire Technology has also developed a remote control mode. In this mode, the operator can directly adjust the fire water cannon mouth up and down, left and right according to the symbols marked on the remote control to carry out the fire extinguishing procedure.

4. Water cannon to fire alarm host: SYV-75-5 (video cable). ( When the water cannon does not have video, there is no need to set up video and remote control lines, and the system does not have remote control function) (6) Fire alarm host to the pump room: RVV4x5 (start pump line, start pump feedback line).

5. Intelligent firefighters are not afraid of the operation method of the linkage control host. For military patrol shops, the linkage host can operate each water cannon, and each water cannon has a unique address in the linkage host. If you select the corresponding address, you can accurately operate each water cannon.

How to draw a comprehensive wiring diagram with visio?

1. Draw a comprehensive wiring diagram with visio: open the network diagram; on the "View" menu, click "Shape Data Window"; click the shape you want to add data; in the "Shape Data" window, select a data domain, and then type the data for the domain; move to the next genus in the list Sex, please press Enter.

2. Open the Visio software.Click "File" - "New" - "Flowchart" and select "Basic Flowchart". Draw the process node. Drag the "shape" required for drawing the flowchart to the drawing area. Draw the process line. Select "Connection Cable Tool" to draw the connection. Identify the direction of the process.

3. The system diagram should be arranged according to the information points of each floor, and the management room of each building should be ten floors per seven floors. The comprehensive wiring of housing comprehensive design and wiring of each floor of the building construction drawing or system plan to understand the separate comprehensive wiring drawing.

4. In the blank space or folder on the desktop, click the right mouse button, and then select the new VISIO drawing. After creating a new one, we can modify the name, and then double-click the newly created document to open it. IT CAN BE SEEN THAT VISIO SOFTWARE PROVIDES A LOT OF TEMPLATES. WE CAN CHOOSE THE APPROPRIATE TEMPLATE ACCORDING TO OUR NEEDS, AND THEN CLICK THE CREATE BUTTON.

5. Next, we adjust the thickness of the lines, select all with ctrl+A, find the tool to adjust the thin bar in the toolbar above the workspace, and select the size that suits you. Such a basic organizational chart has been established.

6. Open the Visio software and import the image material. Click the picture, and then click the width and height in the lower left corner to pop up the size and position dialog box. Set the width and height. Accurately adjust the spacing of the pictures.
