Internet of things application case of wireless module transparent transmission technology

In recent years , With RF Technology 、 The integrated circuit 、 Auto-Control 、 The rapid development of wireless data communication technology , Wireless transmission technology is more and more mentioned , The current smart city 、 Smart agriculture 、 Smart factories need wireless transmission technology to support . The following mainly introduces the specific applications of several point to multipoint wireless communication modules ：

One 、 Application of wireless module in vegetable greenhouse

In recent years , Agricultural greenhouse planting brings great convenience to improve people's living standards , It has been rapidly popularized and applied . Temperature in the planting environment 、 humidity 、 Illuminance 、CO2 Concentration and other environmental factors have a great impact on crop production . The traditional manual control method is difficult to meet the requirements of scientific and reasonable planting , In view of the current development trend of agricultural greenhouses , To realize the automatic monitoring system of the above environmental factors , Using the most popular Internet of things technology today , The air temperature and humidity inside the greenhouse can be obtained remotely in real time 、 Soil moisture temperature 、 Carbon dioxide concentration 、 Light intensity, etc , Realize automatic control of wet curtain fan 、 Spray drip irrigation 、 Inside and outside shading 、 Top window and side window 、 Heating, lighting and other equipment , Ensure that the environment in the greenhouse is most suitable for crop growth , For high yield of crops 、 High quality 、 Efficient 、 ecology 、 Create conditions for safety . Give full play to the role of Internet of things technology in facility agricultural production . The scheme is applicable to various types of solar greenhouses 、 Multi span greenhouse 、 Smart greenhouse . The networking topology is as follows ：

Two 、 Application of wireless module in aquaculture

Aquaculture in China is changing from extensive mode to intensive mode 、 Transformation of industrialization mode , among , The water quality environment of aquaculture has become the most critical link in intensive aquaculture . In the past water quality monitoring, manual detection and recording are usually used , The randomness of water quality monitoring is great , Unable to make timely decisions based on well-known changes 、 Effective response , It is easy to fail to report major accidents 、 Misstatement , Thus causing a large area of aquaculture to suffer harm . With the development of automation technology , The automatic monitoring technology of water quality parameters has been developed and applied , among ,RS485 and CAN It is common to connect the bus mode with the lower computer to realize the monitoring system , It is not too troublesome to remain 、 The high cost 、 Defects with large maintenance . With the development of wireless communication technology , More and more wireless monitoring methods are used in the monitoring of breeding environment , available RF、GPRS And so on . The networking topology is as follows ：

In any field involving data transmission , Wireless data transmission station Can have his place . At present, wireless transmission technology is developing rapidly , There are more and more wireless module manufacturers , Solutions involving public network transmission and private network transmission also emerge in endlessly . Compared with public network transmission , Private network transmission is more and more accepted by users . First, less investment , Cable laying is required for wired communication , Cost material resources and manpower , Rent the public network module , You need to pay for it , The private network transmission module establishes a special wireless data transmission mode , Just connect the wireless data transmission equipment and set up an appropriate antenna at the interrupt , This is especially obvious in long distance and complex terrain ; Second, the service is fast , When it is necessary to connect and communicate with the master station at a distance of several kilometers or tens of kilometers , Wired mode is adopted , Long distance cables must be erected or long cable trenches must be excavated , This project cycle may take several months , And use wireless data transmission equipment to establish special wireless data transmission , You just need to set up an antenna of the appropriate height , The project cycle takes only a few days to complete ; Again, it is adaptable , Wired communication has too many limitations , In some special application environment , For example, when you encounter mountains 、 lakes 、 forest district 、 road 、 Special geographical environment such as buildings or application environment with difficult wiring such as moving objects , It will have a strong restriction on the wiring engineering of wired network , However, the way of using wireless data transmission equipment to establish dedicated wireless data transmission will not be subject to these restrictions ; Finally, the scalability of private network transmission is also relatively strong , After the user has set up a communication network , Often because of the need of the system, new equipment is added . If wired , Rewiring required , The construction is troublesome , And it may damage the original communication lines , However, if the wireless data transmission equipment is used to establish a dedicated wireless data transmission mode , Just connect the new equipment with the data transmission station （ perhaps WiFi modular 、ZigBee Module etc. ） The system expansion can be realized by connecting .

Chengdu ebat Electronic Technology Co., Ltd. has a variety of wireless data transmission modules for public and private networks for users to choose , Its LORA Module series 、SI4463、 Bluetooth module and Zigbee Wireless communication technologies such as modules are widely used in industry and commerce .
