The Research On The Data Acquisition Platform Of The Intelligent Agricultural Planting Process

Intelligent agriculture is supported by the internet of things technology, which integrates information, sensing, wireless communication and other technologies. Based on the deployment of all kinds of sensor nodes and wireless sensor networks in the field of agricultural production, the comprehensive perception, reliable transmission and intelligent processing of agricultural information is completed. Remote data acquisition system is a necessary means to realize the wisdom of agriculture, in order to achieve the efficient management of intelligent agriculture, In view of the lack of intelligent agriculture in data collection methods, network communication security,this paper studies the construction of intelligent agricultural data acquisition and monitoring system platform. The main work of this paper is as follows:1.According to the Modbus protocol, a set of network data communication protocol format is designed, which is designed to solve the environmental parameter acquisition and equipment control of the target monitoring area using wired network and wireless network. And analysis of the function of the embedded server in agriculture data acquisition, Using multiple threads and queuing approach to meet the needs of multi client concurrent and fast response. The CRC verification algorithm is used to resolve the network communication instruction, to guarantee the safety and reliability of information in the network transmission.2.This paper studies the principle of heartbeat detection mechanism and all kinds of heartbeat detection mode and evaluation standard, aimed at solving agricultural iot relative changes due to the geographical range, environmental factors, system network communication failure problems easily. And on the basis of analyzing the heartbeat model, A method of push combined with accelerated heartbeat protocol detection in the client and server is proposed, which is used to determine the connection of the network, reduce misjudgment rate of the system, and improve the system network communication service quality and stability.3.This paper build a tongxiang city gold remote control system, which verifies the proposed the necessity of communication protocols and communication fault diagnosis methods, improve the overall system performance.The research results show that:Based CRC checksum algorithm to ensure the security of information transmission between the two sides of the communication,the method of PUSH combined with accelerated heartbeat protocol can guarantee the normal operation and service of network equipment and applications. Data acquisition equipment control scheme based on the cable and wireless data, realize the information management of the intelligent and high efficiency.
