The equipment control subsystem restarts interchanger and video camera by control relay realization.
4. fault detection and exclusion method according to claim 3, it is characterised in that: the alternating current status information capture
In, status subsystem judges whether that alternating current, which occurs, to be powered off, and powers off when detecting by reading pin level in major cycle
When, Xiang Guanli platform loop sends radio alarming information, up to city power recovery is normal or the electricity of backup power source exhausts；Work as power supply
When recovery, if there is device since voltage change can not work normally, warm reset operation is carried out to equipment.
5. fault detection and exclusion method according to claim 3, it is characterised in that: the network state information acquisition
In, the main program of status subsystem judges network state by heartbeat mechanism, sends a heartbeat under default situations per minute
It wraps and then returns to a response bag after giving management platform, management platform to receive heartbeat packet；Under network abnormal state, status subsystem
The response of management platform will be can not receive, if not receiving within accumulative three minutes response bag, main program has been judged as network connection
It disconnects, is restarted automatically the network equipment of connection at this time, attempt to restore network.
6. fault detection and exclusion method according to claim 3, it is characterised in that: in the video camera information acquisition,
The main program of status subsystem every 10 minutes corresponding switch ports of periodic monitor camera the flow that enters, and to
It manages platform and sends monitored results, to judge the working condition of video camera；
If a) obtaining port flow failure, illustrate that network connection is abnormal, after management platform determines Network Abnormal, is restarted automatically friendship
Trial of changing planes restores network；
If b) obtaining port flow success, and the flow obtained twice in succession does not change, video camera exception is determined, and lead to
It crosses wired mode and sends fault warning information to platform is managed, restart camera power supply manually, do not debug yet such as, then send work
Cheng Shi in-situ processing；
If c) obtaining port flow success, and the flow obtained twice in succession changes, and determines that camera operation is normal.
7. fault detection and exclusion method according to claim 3, it is characterised in that: the O&M chamber door information collection
In, the main program of status subsystem vasculum door state by the way of interrupting；When chamber door state changes, judge to authorize
State when chamber door opens simultaneously unauthorized, sends warning message to management platform by way of wired or wireless communication；Chamber door closes
When closing and having authorized, cancel authorization.
8. fault detection and exclusion method according to claim 3, it is characterised in that: the temperature inside the box information collection
In, O&M the temperature inside the box is communicated by digital hygro sensor timing acquiring using monobus, and the host of status subsystem passes through
The timing of setting accesses to digital hygro sensor, communication time 5ms or so；When temperature is more than the threshold value of setting
When, an excessively high alarm of temperature is sent by state of temperature mark position 1, and to management platform；It will when temperature value restores normal
State of temperature flag bit clear 0, and the flag bit for being transmitted across alarm is removed, it prepares for alarm next time.
9. fault detection and exclusion method according to claim 3, it is characterised in that: the fan-status information collection
In, status subsystem is the PWM square wave that fan inputs fixed duty cycle, detects wind by the square wave that rotation speed of the fan detector is fed back
Whether the revolving speed of fan is abnormal；Fan self-test is safeguarded at service life interval in the major cycle of status subsystem, is detected at one
In period, circle collection rotation speed of the fan feedback low level and counting, when not detecting speed feedback after starting fan, shape
State subsystem sends fan failure alarm to management platform.
