Description
Technical field
The present invention relates to electricity fields more particularly to elevator electric-control system, particularly one kind can detect record elevator automatically
The method of status data.
Background technology
In the prior art, elevator electric-control system in part is controlled using PLC, and after failure, failure is possible to automatically restore just
Often, fault-signal disappears, and elevator can be with normal operation, and since at this moment elevator signal is all normal, inspection personnel is difficult to search and lead
The reason of prior fault of cause, separately needs long-term follow, inspection that could find failure cause, when waste maintenance personal is a large amount of in this way
Between, elevator can only also be run in itself with potential faults for a long time, and there are security risks.
Invention content
It is an object of the invention to be directed to drawbacks described above of the prior art, record state of elevator number can be detected automatically by providing one kind
According to method, this record has instantaneity, is able to record the signal condition of instant of failure elevator, and this status data can be
It searches failure and important evidence is provided.
Its main operational principle is various signals when PLC programmable logic controller (PLC)s collecting device is run and is converted into compiling
Code Signal coding will be recorded for failure judgement type maintenance personal consults afterwards when this moment when device fails.
To achieve the above object, the present invention uses following technical scheme：It can by the switch block of detected elevator and one
Programmed logic controller is connected by electric wiring, and signal storage domain is provided in the programmable logic controller (PLC), will
All external switch amount signals for being detected elevator import the PLC programmable logic controller (PLC)s, then real-time collecting part
The internal signal of external switch amount signal and PLC programmable logic controller (PLC)s converts the signal chosen according to each signal condition
One group of Signal coding is combined by permanent order into digital code, then by the digital code of these signals, when the signal is compiled
When code has differences with preset standard signal coding, which is stored to the signal storage domain, described
Signal storage domain it is full when then delete an earliest record.
Further, judge the record when the signal storage domain space need to completely delete an earliest record
Whether Signal coding is unique in all records, if the Signal coding is unique, then deletes object is changed to be recorded earliest one
The Signal coding that item repeats.
Further, warning lamp is set on the detected elevator, by the defeated of warning lamp and programmable logic controller (PLC)
Outgoing interface connects, and when there is record in the signal storage domain of programmable logic controller (PLC), driving warning lamp sends out signal.
The present invention compares with prior art, and effect is actively and it will be evident that the present invention is not only useful in PLC controls
On elevator device, multi signal can also can be carried out to the on-off model of equipment in the system controlled in other PLC,
The record of all the period of time, it is possibility to have targetedly setting detection signal type, detection period, service personnel, which requires to look up, leads to event
During the signal of barrier, signal state data can be read out of PLC, due to the signal intensity in all setting ranges of data record
Situation, thus by these record data can accurately analyze lead to failure the reason of.
Description of the drawings：
Fig. 1 is flow chart of the method for the present invention.
Specific embodiment
Embodiment:
As shown in Figure 1, a kind of method that can detect record elevator status data automatically, including PLC programmable logic controller (PLC)s,
It is characterized in that, tested measurement equipment is connect with the PLC programmable logic controller (PLC)s by electric wiring, and the PLC, which may be programmed, to patrol
It collects and signal storage domain is provided in controller, all external switch amount signals of the tested measurement equipment import the PLC can
After programmed logic controller, selected part external switch amount signal and PLC programmable logic controller (PLC) internal signals, by what is chosen
Signal is converted into digital code, then the digital code of these signals is combined into one group of letter by permanent order according to each signal condition
Number coding, stores the Signal coding to institute when real-time collected Signal coding and inconsistent preset standard signal coding
Storage region is stated, an earliest record is deleted if having expired in the storage region space.It is exemplified below：Select X1（Door lock is believed
Number）,X2（Frequency converter failure signal）,X3（Overhaul signal）Three signals are detected record, and it is normal that testing conditions are set as PLC
Work（M8000=1）, storage region is：D400 ~ D600, address variable are Z4 (Z4 initial values are 0).When PLC normally after the power is turned on,
PLC specific function relays M8000=1 starts detection record.Under normal circumstances, X1=1 (high level), (height is electric for X2=0 for elevator
It is flat), X3=1 (high level).When loop of the door lock disconnects, when X1 becomes 0 from 1, X1, X2, the corresponding Signal codings of X3 are 001, storage
Module can be 001 storage to address：In D400.Then address variable Z4=Z4+1=1, address variable are directed toward D401, then, X1,
X2, X3, in any one when changing, memory module can be X1 after variation, the state storage of X2, X3 to address：In D401, according to
Secondary to analogize, X1, X2, the data after X3 changes each time can all preserve.In the example, if door lock signal X1 only disconnects moment,
It recovers immediately later normally, when service personnel directly go to check, door lock signal is also normal, can not be pinpointed the problems, and is borrowed
The method for helping the present invention, as long as reading the data in D400（001）Afterwards, according to X1.X2, the correspondence of X3, it is found that, note
X1=0 in record, X2=0, wherein X3=1, X1=0 just represent door lock signal and disconnected, and door lock signal disconnection is elevator in operation
Abnormality, so illustrating that the source of failure that abnormal elevator stops is the reason of loop of the door lock disconnects, it is possible to targetedly
Detailed inspection is carried out for loop of the door lock, is repaired.
Further, judge that the signal of the record is compiled when the storage region space need to completely delete an earliest record
Whether code unique in all records, as the Signal coding uniquely if delete earliest one that object is changed to be recorded it is not exclusive
Signal coding；When limited storage space needs constantly to carry out cycle storage with the old record of new record covering, may examine
The personnel of repairing are watched certain accidental fault-signal record deletion before record, due to this kind of fault-signal may below it is long-term not again
Secondary appearance causes the chance failure of certain component not to be found in time, leaves hidden danger for equipment operation, by Signal coding only
One property judges, it is ensured that the signal record of any component that failure occurred can be retained, and service personnel is made not miss
Any potential failure.
Further, warning lamp is set on the tested measurement equipment, in the PLC programmable logic controller (PLC)s storage region
There is warning lamp during record to send out signal prompting maintenance personal's inspection tested measurement equipment, due to certain component malfunctions
When equipment operation without apparent abnormal, thus by setting apparent mark failure that can be found to solve in time.
