Fig. 1 is the structural representation according to the supervising device applied environment 100 of a preferred embodiment of the present invention.As shown in Figure 1, wherein show main control computer 102 and supervising device 106, communicate to connect between the two.
Operation has main working software 104 on the main control computer 102, is used for the work of subway shield door is controlled in real time.
After main control computer 102 started, monitoring module 108 was determined the working condition of main working software 104 by carrying out process monitoring.The running status of the described main working software 104 of monitoring module 108 regular request, and when detecting number of times that main working software 104 do not respond this running status request continuously and arrive the predefined first unusual threshold value, assert that main working software 104 running statuses are unusual.For example, in the specific implementation process, monitoring module 108 on average per minute is inquired main working software 104 once, if surpass the not response of three main working softwares 104 continuously, think that then main working software 104 occurs unusual, then restart main working software 104, namely destroy last main working software 104 and start example, restart new main working software 104 programs.
In the specific implementation process, in the working time, calibrated a time every one hour between monitoring module 108 and the switch control module 110.When certain deviation appears in the time (can arrange 1-5 minute), monitoring module 108 extracts the clock of the time adjustment switch control module 110 of main control computer 102.The effect of clock alignment is, makes switch control module 110 can guarantee the accuracy of switching on and shutting down time (102 switching on and shutting down of control main control computer), matches with railcar service time and off-running time with this.
