Gas Pipeline Network Remote Wireless Monitoring System

1. Overview Gas Pipeline Network Remote Monitoring System is calculated The machine-based production process control and scheduling automation system is used for on-site monitoring and automated management. Remote monitoring mainly uses RTU as the terminal. At present, there are many forms, such as using PSTN, laying special line radio stations, etc.

2. During the management process of the oil and gas pipeline, surveillance camera equipment will be used for monitoring. In order to make good use of surveillance camera equipment, the following operations need to be carried out: the appearance of the surveillance camera installed indoors will be disguised as some daily necessities. For example, robot ornaments, light bulbs or wall lamps.

3. Pressure isolation station: It is used for water supply enterprises to remotely monitor the water supply network. Staff can remotely monitor the pressure and flow of the city's water supply network at the water department dispatch center. Scientifically direct the start and stop of water supply equipment in various water plants to ensure the balance of water supply pressure and stable flow; timely detect and predict the occurrence of pipe burst accidents.

4. The natural gas remote monitoring system is mainly composed of a dispatch center, a natural gas monitoring center, a communication platform, a natural gas remote measurement and control terminal, measurement (flowmeter, pressure sensor, etc.) equipment, ventilation equipment, etc.

5. Remote monitoring: Step 1: Set up the remote desktop on the remote computer.

Help me see this monitoring system topology diagram

1. Draw college students' mental health supervision The network topology diagram of the measurement system can be carried out according to the following steps: confirmFixed topology: First of all, it is necessary to determine the topological structure of the monitoring system, such as star topology, ring topology or bus topology.

2. Hello, I saw your picture, and there is no problem with the drawing. The output of the video recorder is connected to the matrix, which means that the picture of the video recorder will also be switched in the matrix as a video signal and displayed and output to the TV wall.

3. The far-sighted intelligent network camera has infrared night vision function, which can also be filmed normally in a light-free environment; the up, down, left and right 360° rotating gimbal can greatly expand the monitoring range, avoid monitoring dead spots, and make one camera reach multiple cameras. The effect of use.

Factory Monitoring Scheme

1. In line with the rational use of existing resources, save investment in transformation, make full use of the advantages of wireless video surveillance system, and combine with the most advanced computer technology to realize monitoring image transmission and remote monitoring to provide efficient, feasible and low-cost solutions.

2. The system is advanced and reliable, and the cost is reasonable; it adopts the industry's advanced digital monitoring system, and the main equipment and software are mature imported products. According to the specific characteristics of the factory area, there are many trees, many small animals, etc.; it adopts a Japanese perimeter alarm detector with good anti-misalarm effect, which has strong anti-interference and low false positive rate.

3. Scheme 1: Economical (this plan needs to provide computers and monitors) Quotation: 16 video surveillance cards (hard compression cards), H264 compression format, 16 video inputs; 1200 yuan.

4. This set of video surveillance system is mainly composed of camera part, wireless video transmission part, display and recording part, remote control management and TV wall display part. Wireless monitoring refers to a monitoring system that uses radio waves to transmit video, sound, data and other signals without wiring (cables).

5. According to the overall structure of the factory and fully considering the actual situation on site, the wireless monitoring and transmission system adopts wireless microwave video transmission system and wireless command control system, equipped with ordinary infrared cameras, guns, high-speed balls, and hard disk recorders to realize local loop video recording, retrieval and playback, remote transmission Wait.

6. Set the point according to the area of the warehouse and the dead angle; 2) Choose whether to use a closed circuit or network monitoring Comments | 2011-10-20 13:55 nbyewengui | Second-level You should want a design scheme.
