The analysis and determination process of the four fault types is specifically as follows:
s31, for the abnormal falling alarm of the door closing locking relay of the first shield door fault type, the analysis and judgment process is as follows:
when the interlock sends out a door-closing locking relay driving command BQDPDKJWhen the state of the door closing locking relay PDKJ is changed from 1 → 0, in a period of time before and after the interlocking sends the driving command, if the state of the door cutting interlocking relay is always 0 and the shielding door is not opened, the abnormal falling alarm of the door closing locking relay PDKJ is judged; then according to the acquired locking voltage VPDKJVoltage V for opening doorKMJAnd door closed locking relay status BZCPDKJThe cause of the failure is determined.
The interlock issues a drive command BQD to cause the door to close the latching relay to change state from 1 → 0PDKJIs set to T1In seconds. Under normal conditions, the driving command BQDPDKJDoor closed latching relay status BZC after issuePDKJFrom 1 → 0, when the door is closed and the locking relay is 0, the acquired locking voltage V is comprehensively monitoredPDKJShould also be 0 until a 0 → 1 change in the state of the door-closed latching relay occurs; when the door-closing locking relay is 0, the collected door-opening voltage VKMJShould also be0. In order to be compatible with transmission delay and acquisition glitch phenomenon, the monitoring range of the driving change is expanded to [ T ] according to the actual situation of the field in the embodiment1-3，T1+3]Within the range, the judgment range of the voltage is expanded to: voltages below 5V are considered to be voltages of 0. According to different actual conditions and monitoring sensitivity, different voltages can be selected as expanded voltage judgment standards.
The reasons for the first type of shield door failure include the following three types:
s311, if at [ T1-3，T1+3]Within time, locking voltage VPDKJHaving a collection point lower than 5V and a collected door-opening voltage VKMJAll the voltage values are less than 5V, and the locking voltage acquired by the comprehensive monitoring system and the interlocked driving command accord with the consistency logic, so the abnormal falling alarm fault of the door closing locking relay is caused by a special PDKJ fault of a shield door or an abnormal signal power supply;
s312, if at [ T1-3，T1+3]Acquired locking voltage V within timePDKJAll greater than 5V, acquired door closed latching relay status BZCPDKJThere is a 1 → 0 variation and the collected voltage V for opening the doorKMJAll less than 5V, the door opening voltage VKMJIf the voltage is less than 5V, the shielding door is proved to have no door opening action, and the change of the PDKJ and the locking voltage V are acquired simultaneouslyPDKJThe voltage changes are consistent, so the abnormal falling alarm fault of the door closing locking relay is caused by the misoperation of a signal professional PDKJ;
s313, if at [ T1-3，T1+3]Acquired locking voltage V within timePDKJAll greater than 5V, acquired door closed latching relay status BZCPDKJ1 all the time, and the collected door opening voltage VKMJAll less than 5V, locked relay state BZC due to the door closedPDKJLocking voltage VPDKJAnd a door-opening voltage VKMJAll accord with the time sequence and the performance when the PDKJ does not act, but the interlocked PDKJ state occurs 1 → 0, so the abnormal falling alarm fault of the door closing locking relay at the moment is caused by the interlockingErrors were collected for the state of PDKJ.
S32, the second shield door fault is an interlock driving door opening instruction shield door unresponsive alarm, and the analysis and judgment process is as follows:
when the interlock sends out a door opening relay driving command BQDKMJWhen the state of the door opening relay KMJ is changed from 0 → 1, the interlock relay state BZC is cut if the door is opened before or after the interlock sends the driving commandPDQCJAlways 0 and after the interlock issues the actuation command, the interlock's door closed lock relay state BZCPDKJIf the number of the interlocked driving door opening instructions is 1, judging that the shielded door does not respond to alarm; then according to the collected door opening voltage VKMJAnd a locking voltage VPDKJThe cause of the failure is determined.
Emitting BQD from the interlockKMJT represents the time when KMJ is set to the drive command of 0 → 12In seconds. Under normal conditions, when the interlock sends out a door opening relay driving command BQDKMJAfter that, the door opening relay BZCKMJFrom 0 → 1, when the door-opening relay is 1, the door-opening voltage VKMJShould not be 0 (greater than 5V), locking voltage VPDKJShould be 0 (less than 5V).
The reasons for the occurrence of the second type of shield door failure include the following three types:
s321, if at [ T2-3，T2+3]Within time, the collected door opening voltage VKMJIf all the voltage is less than 5V, the fault is caused by abnormal interlocking driving KMJ or cable open circuit or PSD power supply;
s322, if at [ T2-3，T2+3]Within time, the door opening voltage VKMJHaving a collection point of greater than 5V and at [ T2，T2+3]Locking voltage V acquired in timePDKJIf the voltage is more than 5V, the fault is caused by abnormal shielding door or open circuit of cable from the centralized station to the shielding door equipment room;
s323, if at [ T2-3，T2+3]Within time, the door opening voltage VKMJHaving a collection point of greater than 5V and at [ T2，T2+3]Locking voltage V acquired in timePDKJHaving one collectionPoint less than 5V, when the voltage appears normal, but because of the door cut interlock relay state BZC at this timePDQCJAlways 0, interlocked door closed lock relay state BZCPDKJIf the number of the faults is always 1, the fault is caused because the interlock is abnormal in the acquisition state of the screen door.
S33, the third shield door fault is an interlock driving door closing instruction shield door unresponsive alarm, and the analysis and judgment process is as follows:
when the interlock sends out a driving command BQD of a door closing relayGMJWhen the state of the door closing relay GMJ is changed from 0 → 1, the interlock relay state BZC is switched off if the door is cut off before or after the interlock issues the driving commandPDQCJAlways 0 and after the interlock issues the actuation command, the interlock's door closed lock relay state BZCPDKJWhen the moment of changing to 0 exists and the shielding door does not receive a door opening command, the shielding door is judged to be not responding to alarm according to the interlocking driving door closing command; then according to the collected door closing voltage VGMJLocking voltage VPDKJThe cause of the failure is determined.
Issuing drive commands BQD to interlockGMJThe timing of the drive command of 0 → 1 for the door closing relay GMJ is set to T3In seconds. Normally, the driving command BQD is issued in interlockGMJVoltage V for closing doorGMJNot 0 (more than 5V), locking voltage VPDKJNot 0 (greater than 5V).
The causes of the third type of shield door failure include the following three types:
s331, if at [ T3-3，T3+3]Within time, the collected door-closing voltage VGMJIf the acquisition point is less than 5V, the fault is caused by the abnormal interlocking drive GMJ or the open cable or the abnormal PSD power supply;
s332, if at [ T3-3，T3+3]Within time, the collected door-closing voltage VGMJAre all greater than 5V and are at [ T3，T3+3]Locking voltage V acquired in timePDKJIf the acquisition point is less than 5V, the fault is caused by abnormal shielding door or open cable from the centralized station to the shielding door equipment room;
s333, at [ T3-3，T3+3]Within time, the collected door-closing voltage VGMJHaving a collection point of greater than 5V and at [ T3，T3+3]Locking voltage V acquired in timePDKJAre all larger than 5V, at the moment, the door closing voltage VGMJAnd a locking voltage VPDKJPerforms normally, but due to the now interlocked door closing, the lock relay state BZCPDKJWhen the time point is 0 and the shield door does not receive a door opening command, the fault is caused by abnormal acquisition of the interlocking shield door.
S34, alarming that the fourth shielding door fault is the inconsistent driving command of the interlocking and the collected relay state, and analyzing and judging the process as follows:
will open relay status BZC respectivelyKMJAnd door opening relay drive command BQDKMJClosing relay status BZCGMJAnd door closing relay drive command BQDGMJDoor closed locking relay state BZCPDKJAND gate locking relay drive command BQDPDKJAnd door cut interlock relay status BZCPDQCJAND gate cut interlock relay drive command BQDPDQCJComparing, if there is difference, determining to alarm that interlock and monitoring state are inconsistent, for example, if door opening relay drive command BQDKMJAnd the state is 0 → 1, and the state of the door opening relay is not 0 → 1, the interlocking and monitoring state are inconsistent and the alarm is given.
And distinguishing whether the interlocking is abnormal or the monitoring state is wrong according to the acquired voltage state: if the voltage state change corresponding to each relay is consistent with the state change of each relay, the interlocking driving is abnormal; and if the state change of the voltage of each relay is consistent with the state change of the acquisition of each relay under the comprehensive monitoring, the state acquisition is wrong.

The shielded door alarm method based on comprehensive monitoring as claimed in claim 4, wherein the fault judgment that the interlocked driving door closing command shielded door does not respond to the alarm is represented by: when the interlock sends out a driving command to enable the door closing relay to suck the door from falling, the door cutting interlock relay always falls within a period of time before and after the interlock sends out the driving command, the door closing lock relay has the falling time, and the shielding door does not receive a door opening command.
10. The shielded door collection method based on comprehensive monitoring as claimed in claim 9, wherein the reason why the interlock driving door closing instruction shielded door does not respond to the alarm occurs within a period of time when the interlock sends out a driving command for enabling the door closing relay to suck up from falling is as follows:
in the period of time, if the door closing voltage is 0, the fault is caused by abnormal interlock driving door closing relay or cable open circuit or PSD power supply abnormality;
in the period of time, if the door closing voltage is not 0, and the locking voltage is 0 in a period of time after the driving command is sent out in an interlocking manner, the fault is caused by abnormal shielding door or open circuit of a cable from a centralized station to a shielding door equipment room;
in the period of time, if the closing voltage has a moment which is not 0 and the locking voltages are not 0 in a period of time after the interlocking sends out the driving command, the fault is caused by abnormal acquisition of the interlocking shielding door.
11. The shielded door alarm method based on comprehensive monitoring as claimed in claim 10, wherein the judgment range of the voltage of 0 can be expanded to: the voltage is 0 when the voltage is less than M, and is not 0 when the voltage is greater than M.
12. The shielded door alarm method based on comprehensive monitoring as claimed in claim 11, wherein M is 5V.
13. The shielded door alarm method based on comprehensive monitoring as claimed in claim 4, wherein the fault determination method for alarm of inconsistency between the interlocked driving command and the acquired relay state comprises the following steps: and respectively comparing the state of the door opening relay with the driving command of the door opening relay, comparing the state of the door closing relay with the driving command of the door closing relay, comparing the state of the door closing locking relay with the driving command of the door closing locking relay, and comparing the state of the door cutting interlocking relay with the driving command of the door cutting interlocking relay, and if the four states are different, alarming that the interlocking state is inconsistent with the monitoring state.
14. The shield door alarm method based on comprehensive monitoring as claimed in claim 13, wherein whether the interlocking is abnormal or the monitoring state is mistakenly collected is distinguished according to the collected voltage state: if the voltage state change corresponding to each relay is consistent with the monitored state change of each relay, the interlocking driving is abnormal; and if the state change of the voltage of each relay is consistent with the state change of the acquisition of each relay under the comprehensive monitoring, the state acquisition is wrong.
