县级综合气象业务智能供电系统的设计及应用

Design and Application of a County-Level Integrated Intelligent Power Supply System to Meteorological Service

该系统采用日本三菱PLC作为主要的控制核心,以中间继电器对系统信号进行采集及转化。系统主要由数据处理模块、市电监测模块、无线通信模块、远程控制器、语音识别模块、显示模块、传感器、切换输出模块和UPS电源组成。系统可以实现当市电停电后,自动启用发电机供电;当市电恢复正常时,自动恢复市电供电的功能。为了提高系统的稳定性,系统设有故障报警功能、远程复位功能和远程查询功能等,可实现市电与发电机无缝切换。有效避免了由于市电不稳定而导致气象数据丢失、延误、网络中断等,解决了基层气象台站的供电难题,特别是夜间,为综合气象观测、预报、预警服务提供了稳定的供电保障。

The system uses the Japanese Mitsubishi PLC as the main control core and the intermediate relay system for signal acquisition and conversion,mainly composed of the data processing module,grid monitoring module,wireless communication module,remote controller,the speech recognition module,display module,sensors,switching output module,and the UPS power supply.It can be achieved when power outages occur,the system automatically enables the generator for power supply,and when the power supply returns to normal,it can restore the function of the mains power supply automatically.In order to improve the stability of the system,there are the functions of fault alarm,remote reset,and remote query,etc.,which can realize seamless switching between the mains and the generator and effectively avoid the data loss,data delay,network interruption,etc.,resulted from the instability of the mains power supply,and solve the power supply problem for base stations,especially at night.
