Abstract. The early warning technology of crop diseases and insect pests is a strong guarantee to respond to the increasingly dire situation of major pests and diseases and ensure national food security. At present, the method of the monitoring data collection about the information of diseases and insect pests mainly relies on a field visit carried out by the plant protection staff, sampling and analysis, which directly impacts on the accuracy of early warning analysis. Firstly, the research status of the early warning analysis technology of crop diseases and insect pests in the field of agricultural are investigated and studied thoroughly and deeply, and then the comparison and analysis of the mainstream technology for pest and disease warning and algorithms are done in detail. The final combination of the technology of the Internet of things, a better pest early warning solution of the facility agriculture is put forward in order to provide a useful reference for the study of the early warning of crop pests. Keywords: diseases and insect pests, early warning, facility agriculture, Internet of things, plant protection.

Introduction
There are more than 1400 species crop diseases and insect pests in China. China is one of the countries that the plant diseases and insect pests occur frequently. The crop diseases and insect pests occur frequently each year and bring huge economic losses. At the same time, the problems of crop diseases and insect pests also exacerbated environmental pollution, food safety and other issues. Therefore, it is a particularly important work that ensuring the safety of China's agriculture to timely and effective monitoring, early warning and prevention and management. At present, China still lacks qualified experts and the traditional methods are still used by a majority of plant protection departments to detect the diseases and insect pests, the survey data is filled manually and the information can not be reported to the higher authorities until the diseases and insect pest occurs and then the management work begins. Most traditional approaches are inefficient, timeliness poor and can not make maximum use *

of existing data[1]. It has become an urgent problem to apply existing computer technology and communication technology in the field of detecting the crop diseases and insect pests to build an early warning system of the crop diseases and insect pests. Combined the real-time data and historical data, the system will be able to make advance warning when the crop diseases and insect pests occur. And then the necessary protective measures are
