    • PROBLEM TO BE SOLVED: To easily and correctly recognize causes of failure when notice of abnormality to a monitoring center fails, in a monitoring apparatus configured to notify the abnormality of a broadcast radio wave retransmission system to the monitoring center via a public packet communication network for a portable device when the system has the abnormality.
      SOLUTION: In the monitoring apparatus 6, a monitoring control unit 94 acquires monitoring data indicating the operation state of the system from branching devices 8 or transmission amplifiers 10 constituting the system; and upon detecting the system abnormality from the acquired monitoring data, the control unit 94 generates notification data for notifying the fact to the monitoring center and transmits the generated data to a communication control unit 91. Then, the communication control unit 91 notifies an external monitoring center about the notification data via a packet communication module 90. In this case, when transmitting the notification data, the control unit 91 monitors whether the transmission of the notification data has been normally executed, and if an abnormality occurs in the transmission of the notification data, the fact is stored as a transmission abnormality history in an EEPROM 91d.

    • 要解决的问题:为了在监视中心通知异常的情况下容易且正确地识别失败的原因,在被配置为通过公共分组向监视中心通知广播无线电波重传系统的异常的监视装置中 当系统发生异常时便携式设备的通信网络。 解决方案:在监视装置6中,监视控制单元94从构成系统的分支设备8或发送放大器10获取指示系统的操作状态的监视数据; 并且在从所获取的监视数据检测到系统异常的情况下,控制部94生成用于向监视中心通知事件的通知数据,并将生成的数据发送到通信控制部91.然后,通信控制部91通知外部监视 通过分组通信模块90关于通知数据。在这种情况下,当发送通知数据时,控制单元91监视通知数据的发送是否已经被正常执行,并且如果在通知的发送中发生异常 数据,事实上被存储为EEPROM91d中的传输异常历史。 版权所有(C)2007,JPO&INPIT
