摘要
文中设计一款地震预警信息发布单元,采用ITOP4412核心板作为主控板卡,利用其网络模块通过TCP/IP通信对地震信息推送服务器的数据包进行接收,并根据相关协议对接收数据包进行解析,得到本地地震烈度、地震到达时间、震源发生坐标等信息。通过I/O口驱动控制板卡进行地震烈度报警,同时,通过自带音频模块进行报警广播,利用RS 232通信接口与GLM-430-C触摸液晶屏进行数据交互和报警解除操作,具有地震信息推送报警响应快速、工作稳定等特点。
An earthquake warning information release unit is designed. The ITOP4412 core board is used as the main control board card,and its network module is used to receive the data packet of the seismic information push server by TCP/IP communication. The received data packets are analyzed according to the relevant protocol to obtain the local seismic intensity,earthquake arrival time and focal coordinates. The seismic intensity alarm is carried out by driving control board card of I/O port,the alarm broadcasting is carried out by built-in audio module,and the RS 232 communication interface and GLM-430-C touch LCD screen are used to carry out the data interaction and alarm release operation. It is verified that the unit has the characteristics of fast response to earthquake information push alarm and stable operation.
