基于智能硬件和公共物联网云平台的农业信息采集系统Agricultural information collection system based on intelligent hardware and public Internet of Things cloud platform

技术领域technical field

本发明属于农业种植管理系统,具体涉及一种基于智能硬件和公共物联网云平台的农业信息采集系统。The invention belongs to an agricultural planting management system, in particular to an agricultural information collection system based on intelligent hardware and a public Internet of Things cloud platform.

背景技术Background technique

农业生产环境有着作物品种多样、分布范围广、远离城市、交通不便利等特点,因此在绝大多数的情况下,农业实验监测现场经常处于无人值守的状态,导致信息获取非常困难,不能将信息量精准地进行收集,使农业用户不能精确了解农作物的生长环境,无法及时采取相应的措施来调整农作物的生长环境,从而也就无法确保农作物的正常生长。The agricultural production environment has the characteristics of diverse crop varieties, wide distribution, far away from the city, and inconvenient transportation. Therefore, in most cases, the agricultural experiment monitoring site is often unattended, which makes it very difficult to obtain information. The amount of information is collected accurately, so that agricultural users cannot accurately understand the growth environment of crops, and cannot take corresponding measures in time to adjust the growth environment of crops, so that they cannot ensure the normal growth of crops.

目前,农业信息采集处理包括对农作物的气候,成长环境和产量诸多方面进行的信息采集和处理,而现代化的农作物培植在温室内,这样有助于控制培育良好的农作物生长的环境,提高产量,而农作物气候是指距农作物种植地面几米内的空间气候,农作物气候包括太阳辐射、大气温度、大气湿度、风速等诸多要素,农作物气候随时间、地点、空间发生变化,对农作物的生长、发育与产量产生的影响巨大,而对于采集与处理农作物气候的信息,是对农业生态环境进行模拟、调节和控制的最佳方式,现有的农田气候信息采集处理系统是由计算机控制设备进行控制的综合系统,其主要是按设定的要求对多项要素自动进行采集、处理、存储和编制报表的农业物进行实时的采集处理,然而现有的这些信息采集和处理的系统,其采集方式单一,数据不能有效传输,而且使用的接收设备存在局限,数据传输不精确,所以有待改进。At present, the collection and processing of agricultural information includes the collection and processing of information on the climate, growth environment and yield of crops. Modern crops are cultivated in greenhouses, which help to control the environment for growing good crops and increase production. The crop climate refers to the space climate within a few meters from the crop planting ground. The crop climate includes many factors such as solar radiation, atmospheric temperature, atmospheric humidity, and wind speed. The crop climate changes with time, place, and space. Yield has a huge impact, and the collection and processing of crop climate information is the best way to simulate, adjust and control the agricultural ecological environment. The existing farmland climate information collection and processing system is a comprehensive system controlled by computer control equipment. The system, which mainly collects and processes agricultural objects in real time according to the set requirements, automatically collects, processes, stores, and prepares reports for multiple elements. However, the existing information collection and processing systems have a single collection method. The data cannot be effectively transmitted, and the receiving equipment used has limitations, and the data transmission is not accurate, so it needs to be improved.
