S110 obtains detected value relevant to voltage signal in lift loop；
S120, the comparison result based on detected value and preset threshold, judges whether lift loop breaks down；
If S130, lift loop break down, determines and elevator faults extremely relevant to lift loop occur.
In embodiments of the present invention, based in lift loop and the ratio of the relevant detected value of voltage signal and preset threshold
Compared with, and then determine whether lift loop breaks down.Here, lift loop failure can be lift loop short circuit or elevator
The power supply in circuit is directly broken.It can be voltage collecting device is in parallel with lift loop with obtain lift loop and voltage
The detected value of signal.According to embodiments of the present invention, it accurately can determine whether lift loop breaks down, and then determine whether to send out
Raw elevator faults extremely relevant to lift loop, so that elevator safety accident be prevented trouble before it happens.
In one embodiment, relevant to voltage signal in lift loop to detect the voltage that signal includes loop of the door lock
Signal.The voltage signal of loop of the door lock can be understood as the real-time voltage value of loop of the door lock.The voltage signal of loop of the door lock is obtained,
For example, it may be by voltage collecting device voltage signal to obtain loop of the door lock in parallel with elevator door lock loop.At this point, voltage
Acquisition device can be isolating transmitter, and isolating transmitter can be converted to the actual voltage signal of loop of the door lock in certain model
Interior voltage signal is enclosed, the voltage signal and actual voltage signal after conversion have linear relationship.
In embodiments of the present invention, due to acquisition be conversion after loop of the door lock voltage signal, can be accurate
React the characteristic of loop of the door lock, the i.e. situation of change of the voltage signal of loop of the door lock.And voltage collecting device is with loop of the door lock
Parallel relationship, to loop of the door lock itself without any influence, will not be because of voltage collecting device itself the problem of and influence door
Lock loop.
And if acquire the resistance value of loop of the door lock and then if judging loop of the door lock situation, the resistance value and door lock of acquisition
The actual resistance in circuit does not have linear relationship, and electrical resistance collection device can impact loop of the door lock itself, can not
The characteristic of accurate response loop of the door lock.
As shown in Fig. 2, Fig. 3 and Fig. 6, Fig. 2, Fig. 3 and Fig. 6 are the letter of Yongchun County some elevator of acquisition under normal circumstances
Number, the photoelectricity of voltage signal, this elevator including loop of the door lock is to signal and speed signal.Line 1 indicates loop of the door lock
Voltage signal situation of change, 2 indicate that photoelectricity indicates that elevator speed signal intensity situation, horizontal axis unit are to signal intensity situation, 3
Millisecond, vertical pivot unit are V.
In embodiments of the present invention, it is built where elevator and baffle is installed at each layer of leveling in each floor, in elevator
The predetermined position of carriage installs photoelectric sensor, and here presetting at position can be elevator car roof.When elevator passes through floor
Leveling or when being parked in floor leveling, baffle blocks photoelectric sensor, at this point, the photosignal value of photoelectric sensor detection is
1V.And baffle is not when blocking photoelectric sensor, the photosignal value of photoelectric sensor detection is 0.
In embodiments of the present invention, when elevator is in moving condition, if the voltage value of loop of the door lock is less than preset threshold,
Determine that short circuit occurs for loop of the door lock or the power supply of loop of the door lock is directly broken, here, the power supply of loop of the door lock is directly broken
The power supply for falling can be understood as entire elevator is broken.When elevator remains static, if the voltage value of loop of the door lock is less than
When the static duration that preset threshold and elevator remain static is greater than default first duration, determine that short circuit occurs for loop of the door lock.
Wherein, preset threshold is first voltage threshold value.
Here, the voltage signal of loop of the door lock can characterize the switch gate signal of elevator.Under normal circumstances, when elevator is in
When moving condition, i.e., when elevator movement speed is not 0, elevator door is in close state, and the voltage of loop of the door lock is high voltage, institute
Meaning high voltage can be understood as the voltage not less than first voltage threshold value.Here, elevator is in moving condition and can be at elevator
In moving horizontally state or vertically move state.When elevator remains static, i.e., when the movement speed of elevator is 0, electricity
Terraced door carries out the movement of switch gate, and the voltage signal of loop of the door lock changes at this time, becomes low-voltage from high voltage, then by low
Voltage becomes high voltage, and after the voltage signal of loop of the door lock becomes high voltage again, elevator becomes moving condition from stationary state.Institute
Call low-voltage, can be less than first voltage threshold value and be in close proximity to 0 voltage, for example, first voltage threshold value be 0.2V.
As shown in Figure 4 and Figure 5, Fig. 4 and Fig. 5 is the signal data of some elevator of Quanzhou City of acquisition in abnormal cases,
The photoelectricity of voltage signal, this elevator including loop of the door lock is to signal and speed signal.The voltage signal of the expression loop of the door lock of line 1
Situation of change, 2 indicate that photoelectricity indicates that elevator speed signal intensity situation, horizontal axis unit are millisecond to signal intensity situation, 3, erect
Axis unit is V.
In embodiments of the present invention, loop of the door lock is judged in conjunction with the voltage signal of elevator operation and elevator door lock loop
The case where.For example, when elevator operation is moving condition, i.e., when elevator movement speed is not 0, if the voltage of loop of the door lock
Signal is less than first voltage threshold value, then elevator door lock loop short circuit.When elevator is stationary state, i.e. the movement speed of elevator is
When 0, if the voltage signal of loop of the door lock is less than first voltage threshold value, and the static duration that elevator remains static is greater than first
When preset duration, then the power supply of elevator door lock loop short circuit or loop of the door lock is directly broken, here, the power supply of loop of the door lock
Directly the power supply that can be understood as entire elevator is broken to be broken.For example, the first preset duration is 10 seconds.
Under normal circumstances, elevator is stationary state or when photosignal is 1V, and the voltage signal of loop of the door lock will appear
The variation of high-low-high, that is, elevator door is by normal on and off.As shown in Fig. 4 or Fig. 5, elevator is moving condition or photoelectricity
When signal is 0V, alternatively, the duration that elevator is stationary state is more than the first preset duration, and the voltage signal of loop of the door lock is small
In first voltage threshold value, then illustrate that the power supply of loop of the door lock short circuit or loop of the door lock is directly broken, here, loop of the door lock
Power supply directly broken and can be understood as the power supply of entire elevator and broken, i.e., lift loop occurs abnormal.
According to embodiments of the present invention, can accurately determine whether loop of the door lock occurs short circuit or the power supply of loop of the door lock is straight
It connects and is broken, here, the power supply of loop of the door lock is directly broken the power supply that can be understood as entire elevator and broken, and then is determined
Whether to loop of the door lock extremely relevant elevator faults are occurred, so that elevator safety accident be prevented trouble before it happens.
As an example, can according to the voltage value and elevator state in which of loop of the door lock in running process of elevator,
Judge whether elevator occurs elevator faults relevant to elevator operation.
For example, in running process of elevator, when elevator state in which at least recurs twice from moving condition to quiet
Only when the switching of state, if the voltage value of loop of the door lock remains constant, determine that electricity relevant to elevator operation occurs for elevator
Terraced failure.It is to be understood that be, when elevator operation is at least twice by the circulation of moving condition to stationary state, if
The voltage signal of loop of the door lock does not change, determines that elevator is not belonging to safe operation state.As described above, loop of the door lock
Voltage signal can characterize the switch gate signal of elevator, if the voltage signal of loop of the door lock does not change, then it represents that elevator door
There is no the movement of switch gate, at this point, it is very unsafe that i.e. elevator, which opens a movement, there may be the situation for the ladder that opens the door
Operating status.At least twice by the circulation of moving condition to stationary state it is to be understood that the operating status of elevator is " movement-
It is static-mobile-static " or " mobile-static-mobile-static-mobile-static ".
Here, circulation is to judge by accident in order to prevent at least twice, because most of elevator all has the function of automatic homing
Energy, i.e. elevator are after certain time length without passenger in use, default floor is revert to by current floor automatically, at this point, elevator door is
Switch gate movement is not needed, i.e. the voltage signal of loop of the door lock is not in variation.
In another example when elevator state in which switches to stationary state by moving condition, and elevator remains static
When static duration is greater than default second duration, if the voltage value of loop of the door lock remains constant, determines whether to have in elevator and multiply
Visitor.If there is passenger in elevator, determine that elevator faults relevant to elevator operation occur for elevator.It is to be understood that being to work as elevator
Operating status is moving condition to stationary state, and when static duration is greater than the second preset duration, if the voltage of loop of the door lock is believed
Number do not change, then illustrates that elevator door is constantly in closed state.Further judge whether there is passenger in elevator, if in elevator
There is passenger, then illustrates the case where closing people there are elevator, this is very unsafe operating status.Here it is possible to utilize infrared biography
Sensor judges whether there is passenger in elevator, or the acquisition image of elevator interior is obtained using image collecting device, according to acquisition
Acquisition image judge whether there is passenger in elevator.If there is passenger in elevator, alarm immediately, notify relevant staff into
Row is sued and laboured and is repaired.
In embodiments of the present invention, the case where elevator closes people with the presence or absence of the terraced or elevator that opens the door can be found in time,
The serious accident of elevator is prevented trouble before it happens.
In another embodiment, detection signal relevant to voltage signal includes the voltage value of safety return circuit.If peace
The voltage value of full loop is less than preset threshold, determines that short circuit occurs for safety return circuit or the power supply of safety return circuit is directly broken,
Here, the power supply of safety return circuit is directly broken the power supply that can be understood as entire elevator and is broken.Wherein, preset threshold
Two voltage thresholds.
It is to be understood that being, detection signal relevant to voltage includes the voltage signal of safety return circuit in lift loop.
The voltage signal of safety return circuit can be understood as the real-time voltage value of safety return circuit.The voltage signal of safety return circuit is obtained, for example,
It can be voltage collecting device voltage signal to obtain safety return circuit in parallel with elevator safety loop.At this point, voltage acquisition
Device can be isolating transmitter, and isolating transmitter can be converted to the actual voltage signal of safety return circuit in a certain range
Voltage signal, voltage signal after conversion and actual voltage signal have linear relationship.
In embodiments of the present invention, acquisition be conversion after safety return circuit voltage signal, can accurate response safety
The characteristic in circuit, the i.e. situation of change of the voltage signal of safety return circuit.And voltage collecting device and safety return circuit are parallel relationships,
To safety return circuit itself without any influence, will not be because of voltage collecting device itself the problem of and influence safety return circuit.
And if acquire the resistance value of safety return circuit and then if judging safety return circuit situation, the resistance value and safety of acquisition
The actual resistance in circuit does not have linear relationship, and electrical resistance collection device can impact safety return circuit itself, can not
The characteristic of accurate response safety return circuit.
As shown in fig. 7, under normal circumstances, no matter elevator is moving condition or stationary state, the voltage letter of safety return circuit
It number should be always high-voltage state, so-called high voltage can be understood as the voltage not less than the second preset threshold.If safety is returned
The voltage signal on road is less than second voltage threshold value, determines that short circuit occurs in voltage circuit or the power supply of safety return circuit is directly broken
Fall, here, the power supply of safety return circuit is directly broken the power supply that can be understood as entire elevator and broken.For example, second voltage
Threshold value is 0.2V.
According to embodiments of the present invention, can accurately determine whether safety return circuit occurs short circuit or the power supply of safety return circuit is straight
It connects and is broken, here, the power supply of safety return circuit is directly broken the power supply that can be understood as entire elevator and broken, and then is determined
