2022-06-20 1024

Ultra-long-distance wifi module oil pipeline factory fishing port security monitoring solution, the customer needs to install video surveillance in key parts along a certain oil pipeline, the whole line is 147 kilometers in total, there is a valve room every 10-20 kilometers along the pipeline, and there are optical fiber connections in the valve room . Due to the large number of front-end monitoring points, which are distributed along the line, the construction of laying optical fibers is difficult and the cost is high, and it is necessary to wirelessly transmit and return monitoring images. The control center and front-end monitoring points are powered by solar energy.

Ultra-long-distance wifi module oil pipeline factory fishing port safety monitoring scheme

Option One:

The video data collected by the front-end monitoring point is transmitted to the nearby valve chamber through the ultra-long-distance wifi module wireless network bridge, and the optical fiber is connected to the valve chamber, and then uploaded to the private network through the optical fiber. Each surveillance squadron can watch through the private network and obtain relevant surveillance video. At the same time, the data of each monitoring squadron is collected to each monitoring squadron through the fiber optic network and transmitted to the general control center. If the front end is shielded, it can be transmitted through multiple jump relays.


Option II:

The video data collected by the front-end monitoring point is directly transmitted to the nearby supervision squadron through the ultra-long-distance wifi module wireless network bridge. Each supervisory squadron can watch through a special network and obtain the corresponding surveillance video. At the same time, the data of each supervising squadron can be transmitted to the general control center through a fiber optic network. If the front end is blocked, multiple hop relays can be used to transmit.


Wireless transmission wave wireless transmission problem:

Due to the limited coverage of the factory's wired network, the difficulty and high cost of re-laying optical fibers, the manufacturer decided to use a wireless transmission system solution. The wireless transmission system needs to transmit the surveillance video of the four points back to the surveillance center. There are many houses blocked between the remote sump pump location and the monitoring center, requiring transmission through multiple hop relays.


Design:

Install the ultra-long-distance wifi module device at the sewage pump position, and transmit the camera image to the house position through the device; install two wave devices at the house position, one is used to receive the video returned by the sewage pump, and the other is used to connect the sewage pump to the house. The monitoring image of the house location is transmitted to the gate location; two ultra-long-distance wifi module devices are installed at the gate location, one receives the front-end return video, and the other returns all videos to the monitoring center; two microwave devices are installed in the monitoring center, respectively Receive videos from barriers and hazardous chemicals rooms. The staff can watch the monitoring center in real time and monitor the front-end monitoring.


Safety Monitoring Plan Fishing Port Wharf Construction:

1. Demand analysis

The on-site safety monitoring project of fishing port and wharf is mainly applied to the project site. Due to the serious corrosion of salt spray at the seaside, we use high-efficiency and stable digital wireless equipment to achieve this. Considering the specific conditions of the site, according to the site description, it is still in the construction stage.

We have designed a set of economical and practical ultra-long-distance wifi module wireless solutions for wiring difficulties and later wiring risks. The general idea is to use industrialized point-to-point and point-to-multipoint transmission.


2. System Platform Design Principles


advanced

The so-called advanced means that the product conforms to the new development trend of computer and network communication technology, and the application of mature system is the application result of contemporary advanced computer technology.


Confidentiality and Security

In order to protect internal information, especially classified information, from unauthorized access, it must comply with national security standards and requirements. When designing the system, the ultra-long-distance wifi module should fully consider the security of the database and application system, and establish MAC address-based identity authentication, authority authentication and IP authentication to completely shield illegal access by unauthorized users inside and outside.


Intelligent


Independent programming, memory function, active detection, etc. are the intelligent features that the products used in the system and the system itself must have; front-end equipment and systems must have good and reliable communication capabilities, automatic fault detection, and alarm functions.


Digitizing

In recent years, the digital trend of ultra-long-distance wifi module monitoring products has become more and more obvious. I believe that as technology continues to advance, digital systems will be further and more widely used. However, the digital signal suffers less interference, less line loss, convenient storage, and convenient upgrades. Therefore, we must build the TV monitoring system into a highly digital and information-based system.


network

In order to adapt to the progress of the times, the advancement of technology, and to meet wider inspection requirements, in the information society where computer network technology is highly developed and widely used, the products and systems used must be combined with computer network technology to realize the various subsystems. Information Sharing.


practicality

The practicality we are talking about here refers to the required products and technologies that can meet the needs of the current monitoring system, rather than flashy doubts, after the test of the market, never blindly invest and waste money.


mature

It must be a mature product that has passed the test of the market for a certain period of time, especially in China, there should be cases of successful application, products and systems used in system design.


flexibility

When designing the system, the required functions should be reasonably configured, and the configuration should be able to change, even after the project is completed, changes in functions and configurations are possible and convenient.


Ease of use

The front-end products and system software of the ultra-long-distance wifi module system have good ease of use. Especially in terms of operation, general managers should be able to master the essentials of system operation and complete monitoring tasks through training under rough computer operating conditions.


reliability

Ensuring that the system operates reliably and stably is a design principle that must be followed. There are two aspects to this principle:

Reliable system operation - The operation of the system is required to be reliable. Careful reliability certification is required for all equipment, from the configuration of the computer to the configuration of the system, as well as the configuration of the front-end equipment.


Easy to save and restore settings - In practice, problems can arise even if the system has a low failure rate for a variety of unexpected reasons. Therefore, when designing the system, we should consider the convenience of system data saving and quick recovery.


openness

Even advanced systems have the potential to fall behind over time. In the system design, we should fully consider the upgrade, expansion and maintenance of the system. When choosing ultra-long-distance wifi module products and systems, we should fully consider the upgrade and expansion of the system. Design should be comprehensive and thoughtful. We should pay attention to keep it in place and leave enough margin to meet the needs of future development. Mainly reflected in the following aspects:


Smart Upgrades - System software is most likely to be upgraded. The selected systems management software must be guaranteed free upgrades by the manufacturer. The operation of upgrading should be relatively simple, and it can be done by system administrators without complicated operations and special techniques.


Modular structure - The equipment used in the design should be a highly integrated modular product to facilitate hardware maintenance and upgrades. The system it consists of should be of modular structure. In this way, maintenance and upgrade of the system are facilitated.


Economical practicability - In order to ensure rationality, we should choose systems and products with superior performance and price ratios on the basis of satisfying other basic principles, so that the system investment is worthwhile.
