Chapter I: Project Overview Security protection technology is a product of modern science and technology. It embodies the perfect combination of modern electronic technology, modern communication technology, modern control technology and modern computer technology. Its characteristics lie in the multiple information it uses. Collection, transmission, monitoring, recording, management, integration and integration of a series of high-tech. Practice has proved that the use of this technology constitutes a security system (referred to as the security system), can provide a safe, convenient and comfortable protected space for the construction environment. The monitoring system is an indispensable part of the security system. It not only can monitor the monitoring site in real time, but also can clearly record the monitoring content through various storage media for verification at any time.
With the rapid development of the national economy, modern agriculture has made great progress. Greenhouse engineering has become an important part of high-efficiency agriculture. Since the advent of computerized intelligent greenhouses, it has become an important means and measure for the development of modern agriculture. Its function is to use advanced technology and modern facilities to artificially control the environmental conditions of crop growth so that crop growth is not affected by the natural climate, so that it can be factory-built all year round to produce high-efficiency, high-yield, and highly-efficient production.
In recent years, the cultivation of agricultural greenhouses has brought great convenience to people's living standards and has been rapidly promoted and applied. Environmental factors such as temperature, humidity, light intensity, and CO2 concentration in the planting environment have a great influence on the production of crops. Real-time monitoring and management of crop growth has become an essential means.
In view of the current trend of the development of agricultural greenhouses, our company has proposed a design of a remote monitoring system for greenhouses. According to the special characteristics of greenhouse monitoring, it is necessary to transmit greenhouse video and other parameters to the managers, and send the managers' orders to the on-site execution equipment. At the same time, the upper-level department must be able to understand the real-time information of the regional greenhouses through the Internet or mobile phone information at any time. situation. 802.11-based wireless transmission technology makes it possible to remotely monitor video and field environment in agricultural greenhouses.
The second chapter: The project design The user's site is an intelligent agricultural ecological construction shed, in which a total of 276 greenhouses, each with three surveillance cameras installed, including a billiard camera, two gun cameras, in addition to two balls The camera is installed at the gate of the park. Due to the special environment within the park, it must be transmitted wirelessly to the monitoring center. The park initially plans to deploy five fiber access points, and the cameras in the greenhouse will be transmitted wirelessly to five fiber access points. Finally watched at the monitoring center.
The monitoring points of the park are basically installed inside and outside the agricultural ecological greenhouses. Due to the large number of greenhouses, the sub-regional summary method is used first. Each shed is shown below:
First of all, the first step is to integrate the front-end sheds with wires. About 10 sheds are aggregated using switches. Then, the SF-5823WJ products of our company are used for transmission, and they are transmitted to the fiber access points in a wireless manner. As shown below:
Each fiber access point can summarize the surveillance images of 180 cameras, as shown in the following figure:
The figure above shows a wireless transmission scheme for a fiber access point. In this solution, two fiber access points are required to use the above aggregation scheme.
Each fiber access point summarizes the surveillance images of 150 cameras, as shown in the following figure:
In the figure above, there are a total of 150 cameras, which are transmitted to the fiber access points using digital wireless transmission devices. The aggregation of the two fiber access points is required in the above manner.
After summarizing according to the above scheme, the last fiber access point also needs to aggregate 140 cameras, as shown in the following figure:
Chapter 3: Product Use In this solution, because there are many monitor images, it is recommended to use our company's high-bandwidth digital wireless transmission device SF-5823WJ, which has the characteristics of large transmission power and high transmission bandwidth. More suitable for the use of large-scale scenes.
