中文摘要:目前气象业务中,新一代天气雷达组网建设不断完善,其在短时临近灾害性天气预报、预警业务和决策服务中越来越发挥着不可替代的重要作用,因此,做好新一代天气雷达的业务运行保障工作非常重要。针对新一代天气雷达发射机软硬件复杂、故障频发、维修时效长、维修难度大等特点,研制了新一代天气雷达发射机常用芯片自动检测系统。该自动检测系统采用了机外脱机测试方法,从而保证了雷达设备和人身的安全;采用了发光二极管指示灯直接输出测试结果的自动测试方式,保证了雷达修复的较短时效;可直接测试雷达组件内部电路板常用关键芯片的好坏,而不必更换整个笨重的分机组件备件,从而使维修新一代天气雷达发射机故障变得便捷、高效、经济。新一代天气雷达发射机常用芯片自动检测系统研制完成后在多个台站得到了试用,试用效果良好,可为其他新一代天气雷达站快速维修新一代天气雷达发射机提供借鉴和参考。

Research on Chips Automatic Detection Technology for the Transmitter of Next Generation Weather Radar
Abstract:At present,the construction of the next generation weather radar network is constantly improving and it plays an increasingly important role in short time nowcasting disastrous weather forecast,early warning and decision making services. Thus,it is very important to ensure the operation of the new generation of weather radar. Aiming at the characteristics of the next generation weather radar,such as complex hardware and software of transmitter,frequent failures,long maintenance time and great difficulty in maintenance,a new chip automatic detection system for weather radar transmitter is developed. This system adopts the off board offline test method to guarantee the safety of the radar equipment and operation staff. The light emitting diode indicator is used to output the test results automatically,which ensures the efficiency of the radar repairing. In addition,this automatic detection system can directly test the quality of the key chips of the internal circuit board of the radar components instead of replacing the entire bulky spare parts,thus making it convenient,efficient and economical to repair the fault of the radar transmitter. Actually,this automatic chips detection system for the next generation weather radar transmitter has been tested at several stations since its coming into being and the trial effect is good. So,the system can provide references for other weather radar stations in China to quickly repair the next generation weather radar transmitter.
