摘　　要：随着科学技术的进步和计算机相关科学的快速发展,智能设备产品在各种环境得到越来越广泛的应用,在某种程度上影响了人类的生活和生产方式。当前,中国气象业务已利用智能传感器和计算机软件来帮助完成各项气象探测工作,改善了气象业务的管理和服务方式,极大地方便了气象工作人员的管理工作,提高了工作效率,但是其中也存在着一定的缺陷。比如,当前气象观测中,传感器与数据采集器连接线路冗杂,探测设备集约型太差,且达不到"局站分离"的目的。随着气象行业的不断发展,为改善当前地面气象观测综合系统所存在的问题。基于嵌入式系统原理和电路原理,高频电子线路原理,以ARM体系结构Cortex-A7内核为核心的新型地面气象观测综合集成硬件设计,该设计的微处理器采用恩智浦公司i.MX6UltraLite处理器,具有高性能、低功耗和低成本的特点,符合工业级的标准,被广泛地应用于嵌入式系统设计领域。该综合集成硬件设计具有6个全功能串口通道,1个Debug调试串口通道,一个GPRS串口通道,且具有低功耗Wi-Fi和蓝牙无线通信等功能。新型地面气象观测综合集成硬件还实现将现有地面综合观测业务软件(ISOS)中的SMO部分功能从PC端下移到综合集成硬件上面,从而打破了PC电脑的限制,简化观测流程,提高了气象观测工作人员的效率,也符合中国气象行业发展的需求。With rapid development of computer-related science, intelligent equipment products are more and more widely used in various environments, which affects the way of human life and production to a certain extent. At present, China meteorological industry has used intelligent sensors and computer software to help complete the meteorological detection missions, which improves the management and service mode of meteorological industry, greatly facilitates the management of meteorological staff, and improves the work efficiency. But there are still some shortcomings. For example, in the current meteorological observation, the connection lines between sensors and data collectors are complex and the intensive type of detection equipment leaves much to be desired, failing to achieve the purpose of "separation of bureau and station". With the constant development of the meteorological industry, in order to improve the existing problems of the current surface meteorological observation integrated system. Based on the principle of embedded system, circuit and high frequency electronic circuit, a new ground meteorological observation integrated hardware design is presented in this paper. The core of this design is the Cortex-A7 core of ARM architecture. The microprocessor of design using the i.MX6 UltraLite processor of NXP Company, which has the characteristics of high performance, low power consumption and low cost, as well as meets the industrial standard. This microprocessor is widely used in the field of embedded system design. The integrated hardware design has six full-function serial channels, one Debug debugging serial channel and one GPRS serial channel, as well as has low power Wi-Fi and Bluetooth wireless communication functions. The new integrated hardware of ground meteorological observation also realizes the transfer of SMO functions from PC to integrated hardware, which breaks the limitation of PC, simplifies the observation process, improves the efficiency of meteorological observation staff, and meets the dem
