[Abstract]:Obtaining first-hand field monitoring data can provide data support for the research environment, climate change and natural disasters. For a long time, such monitoring mainly relies on manual monitoring, which is vulnerable to weather and has poor reliability.It is also unable to meet the needs of large-scale long-term monitoring in the field.Based on the field environment parameter automatic monitoring system based on ZigBee, various kinds of high precision sensors are used to realize the automatic monitoring of the environmental information in the monitoring area, so that the researchers can know the change of the environmental characteristic parameter in the first time.Timely and effective response measures can greatly reduce the intensity of field manual monitoring.In this paper, the WSN gateway in the field environment parameter automatic monitoring system is designed, the basic function and structure of the remote communication gateway are introduced, and the current WSN gateway which is connected by the central node and PC through serial port is analyzed.In order to extend the network communication module as a gateway at the central node and its disadvantages such as laying cable, special field computer room and so on, a WSN remote application gateway based on Android platform is designed.The system is developed under the Eclipse-android environment, the development cost is low and the application program has good portability. The wireless transmission mode realized by the wireless communication development kit is less constrained by the monitoring environment, and the facilities are simple and convenient.And can solve the general gateway data storage problem.In this scheme, Huawei V880 mobile terminal is used as the carrier to complete the communication transfer function, and the management function of the gateway is further improved according to the functional requirements of the gateway.In the development of gateway communication function, the Bluetooth communication with the underlying coordination node and the network communication between the Internet and the monitoring center via 3G network are included.On this basis, the design method of WSN time synchronization is analyzed, and the UTC time is selected as the system synchronization reference signal. In the aspect of data processing, the special SQLite database is developed on the Android platform to manage and store the data.System node configuration management and task scheduling to ensure the correctness of the received information and accurate release of the measurement task; complete the backup of data in the gateway part of the reservation; in the measurement task and status reporting section,FTP upload is used to realize the interaction with the monitoring center server.Finally, this paper introduces the development environment and testing situation of the gateway, adopts serial port debugging assistant SSCOM3.2 and TCP/UDPSocket debugging tool Quick Easy FTP Server4.0.0 to test the module and the whole function of the designed application gateway.The results show that the application gateway can realize the communication between the upper and lower layers, the management functions of the gateway and the data reporting requirements.
