Remote transmission wifi module data transmission farmland/forest wireless AD hoc network application, smart agriculture is the specific performance of smart economy, is an important part of smart economy; "Smart agriculture" is to make full use of the achievements of modern information technology, integrate the application of computer and network technology, Internet of Things technology, audio and video technology, long-distance transmission wifi module data transmission technology, wireless communication technology and expert wisdom and knowledge, realize agricultural visual remote diagnosis, remote control, disaster warning and other intelligent management. Intelligent agriculture is an advanced stage of agricultural production. It is an emerging technology of Internet, mobile Internet, cloud computing and Internet of Things. Relying on various sensor nodes deployed on the agricultural production site (ambient temperature, humidity, soil moisture, carbon dioxide, images, etc.) and wireless communication network, it can realize the agricultural production environment, intelligent early warning, intelligent decision-making, intelligent analysis and online guidance of experts. Provide accurate planting, visual management and intelligent decision-making for agricultural production.
>> Application requirements
At present, the customer's actual demand is: real-time monitoring of growth and soil conditions in three smart farmland test fields in 20 square kilometers of mountain farmland. Each experimental field needs about 15 poles, equipped with solar-powered street lights, cameras and soil testing instruments. Video and testing data are transmitted to the monitoring room through long-distance wifi module wireless AD hoc network. Agricultural experts use the data to develop more scientific planting methods and greatly improve crop yield.
>> Solution
The distance between the three test fields is about 3-4 kilometers. Some places have hills and cannot transmit directly to the monitoring center at the same time. Our company proposes to collect 15 data from each test field to one point according to the field topography, and then use Gigabit network bridge to directly transmit the collected data to the monitoring center. Due to the topography, two points need to be collected, one way to the monitoring center and the other way to the observation platform. West Zhuang terrain is a little clustered, can be directly transmitted to the monitoring center. Due to the large altitude difference, our company recommends the low point and relay transmission to the viewing platform. If other points have the conditions of direct transmission of the observation platform, long-distance transmission wifi module data transmission can be many-to-one transmission. After aggregation, the gigabit bridge is transmitted directly to the monitoring room. There are two points around the monitoring room to receive data, which can avoid signal interference from multiple receiving network Bridges and provide more stable data transmission for customers. The antenna of the wifi module adopts a 120-degree flat plate antenna, and the wireless signal at the transmitter can be received at a large Angle. The wireless equipment adopts a universal network interface, which is convenient for customers to connect various switches and video recorders. Our company has configured the solar power supply mode.
Forest resources fire warning long-distance transmission wifi module transmission wireless communication transmission case
Background of the Project
In recent years, with the increasing attention to forest fire prevention, forest fire prevention has become an important index of construction. The wireless transmission project of forest fire prevention is located in the southeastern edge of the Qinghai-Tibet Plateau, connecting the western mountain plains of Sichuan and Hengduan Mountains. It is located in the northwest hilly plateau of Sichuan, with an average elevation of 3,500 meters above sea level.
As a key forestry county in the province, the forest area is 7.53 million mu and the forest coverage rate is 51.33%. The total accumulation of living trees is 36.2089 million cubic meters, distributed in the Yalong River, branch ditch along the coast of 4200 meters above sea level. It is the main forestry county of this operation. There are conifer species, broad-leaved tree species and various economic trees. At the same time, there are also a variety of national first and second class protection animals and a variety of precious Chinese medicine resources. In case of fire, the damage is incalculable. Therefore, the installation of long-distance transmission wifi module wireless transmission is imperative!
Project Status
Fortunately, I was invited by a unit to participate in the design and on-site installation of wireless transmission scheme of forest fire prevention project. Choose a number of points, far from the county line more than 40 kilometers, there are many 5000 meters in the middle of the mountain, long-distance transmission wifi module professionals through technical means, designed the forest fire transmission program, through a series of remote transmission, by setting up relay transmission, can monitor the scope of multiple important fire points in the county office.
The long-distance wifi module of the project has been put into operation smoothly, providing strong technical support and 24-hour uninterrupted monitoring and early warning for forest resource protection.
