步骤 5 : 接着, 该微处理机则进入休眠状态, 而该计时模块继续计时 438。 请同时参阅图 3及图 5A〜D所示, 本发明的实施示意图, 先进行压力位准及 振幅侦测及负压侦测范围及压力警报上下限的设定值设定:
1.该压力位准及振幅滤除范围 511设定在 0〜2Kgf/ cm2
2.该负压侦测范围 512系设定在 OKgf/cm2以下;
3.该压力警报上限值 513设定为 3. 3〜3. 7Kgf/ cm2, 而压力警报下限值 514 设定为 0. 3〜0. 6Kgf/ cm2 , 且该压力位准及振幅侦测 511、 负压侦测 512、 警报 上限 513及压力警报下限 514均可为随时间变化的曲线或为直线, 可透过软硬体 方式进行调整及设定, 或取消侦测的功能。
如图 5A〜D所示, 当压力突波侦测模块 13取得压力量测范围信号 501 (图 5A 所示) 或压力小幅波动信号 502 (图 5B所示)在 0〜2Kgf/ cm2以内, 或侦测到压 力振幅信号 503 (图 5A〜D所示) 时, 即会将该信号 501、 502、 503滤除, 接着 侦测压力斜率与压力斜率变化率, 当侦测到正压力斜率异常信号点 505及负压力 斜率异常信号点 507时, 即刻于 0. 0001秒唤醒微处理机 14, 进行 0. 001秒连续 信号压力读取, 并储存至内存 17后, 再经由网路模块 16将警报讯息发送至远程 监控装置 6, 或直接控制现场设备, 以进行紧急处理, 直至侦测到正压力斜率消 失信号点 506或负压力斜率信号消失点 508,即会控制微处理机 14进入休眠状态。
另外, 如图 5C所示, 若压力突波侦测模块 13判断斜率信号为正常斜率信号
504时, 即会将该斜率信号 504号滤除, 判断为正常压力。
另外, 该负压侦测模块 18或侦测到负压侦信号低于 OKgf/cm2以下, 同样会 在 0. 0001秒内唤醒微处理机 14。
另外,若压力警报上下限侦测模块 19侦测到压力信号低于 0. 3〜0. 6Kgf/ cm2 或高于 3. 3〜3. 7 gf/ cm2时, 同样会在 0. 0001秒内唤醒微处理机 14。
另外,该突波压力侦测模块 13的正负压力斜率及斜率变化侦测均为可随时间 变化的曲线或直线, 可透过软硬体方式进行调整及设定, 或取消侦测的功能。 另外, 上述的设定值仅代表本案之较佳实施例, 并非用以局限本案的权利要 求范围。
