PURPOSE:To decide whether trouble information exceeds a threshold value or not, and to collect detailed trouble information with simple constitution by storing a decision pattern indicating a trouble section and the decided threshold in a memory, and comparing the collected trouble information with the decision pattern successively read out from the memory. CONSTITUTION:Stations 3-8 constituting plural communication networks connect between a transmitting terminal station 1 and receiving terminal station 2. An I/O control part 15 in a monitoring device 10 is connected to the receiving terminal station 2 and a microprocessor 11 is connected to a control part 15 through a common bus 12. A program memory PM and a memory MEM14 storing the decision pattern and the decided threshold value are connected to the bus 12. In the monitoring device 10, the trouble information collected from the stations 3-8 are compared with the decision pattern successively read out from the MEM14 by a processor 11. The compared result is compared with the decided threshold to decide whether respective trouble sections are overlapped or not. Thus, the detailed trouble information is collected with simple constitution. |
