scvsmaglog

记录 VS 震级信息

描述

scvsmaglog 记录来自 scvsmag 的 VS 震级信息，一旦事件超时，生成报告文件。

scvsmaglog 实现 ActiveMQ 接口，能发送消息至 UserDisplay —— Caltech 开发的实时 EEW 用户界面。

报告

ActiveMQ 接口

事件消息

首个震级估算有效时将发送事件消息。第一个消息的message_type是new，其他消息的为update或delete。当前，除了不可靠估算外所有的值均由 scvsmaglog 设置。

<?xml version='1.0' encoding='UTF-8'?>
<event_message message_type="new" orig_sys="dm" version="0">
    <core_info id="-9">
        <mag units="Mw">-9.9</mag>
        <mag_uncer units="Mw">-9.9</mag_uncer>
        <lat units="deg">-999.9</lat>
        <lat_uncer units="deg">-999.9</lat_uncer>
        <lon units="deg">-999.9</lon>
        <lon_uncer units="deg">-999.9</lon_uncer>
        <depth units="km">-9.9</depth>
        <depth_uncer units="km">-9.9</depth_uncer>
        <orig_time units="UTC">2013-06-10T13:35:12Z</orig_time>
        <orig_time_uncer units="sec">-9.9</orig_time_uncer>
        <likelihood>-9.9</likelihood>
    </core_info>
</event_message>

心跳消息

心跳消息每隔 5 秒钟发送一次。

<?xml version='1.0' encoding='UTF-8'?>
<hb originator="vs.9" sender="vs.9" timestamp="Mon June 10 13:41:35 2013" />

ActiveMQ 代理配置

<connector>
<serverTransport uri="stomp://your-server-name:your-port"/>
</connector>

用户示例

#!/usr/bin/env python
from stompy.simple import Client
stomp = Client(host='your-server-name', port=your-port)
stomp.connect(username='username', password='password')

stomp.subscribe("/topic/heartbeat")
stomp.subscribe("/topic/alert")
while True:
    message = stomp.get()
    print message.body
stomp.unsubscribe("/topic/heartbeat")
stomp.unsubscribe("/topic/alerts")
stomp.disconnect()
