In being described below, for illustration and not for limitation, the tool of such as particular system structure, technology etc is proposed
Body details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention also may be implemented in the other embodiments of details.In other situations, it omits to well-known system, device, electricity
The detailed description of road and method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.
Referring to Fig. 1, Fig. 1 is the flow chart of elevator safety monitoring method provided in an embodiment of the present invention.As shown in Figure 1,
The elevator safety monitoring method of the present embodiment the following steps are included:
S101: whether institute is deviateed by the operating parameter that the intelligent terminal in elevator detects the elevator current operating conditions
State the normal operating condition of elevator.
In the embodiment of the present invention, intelligent terminal (for example, smart phone) the acquisition elevator that can be first passed through in elevator is worked as
The operating parameter of preceding operating status, then judge whether the operating parameter of the elevator current operating conditions is deviateing the elevator just
Normal operating status.The normal operating condition of the elevator may include the Gaussian Profile or variation of operating parameter when operating normally
Rate.Wherein, the operating parameter mainly includes acceleration, speed and angular speed.Since elevator is by motor, pulley and hawser etc.
Transmission, hawser hangs carriage by extending downwardly at the top of elevator, therefore, when the carriage of elevator is in different floors, i.e.,
Carriage to the hawser of elevator length difference when, hawser entirety tension is different, and when carriage is located at a certain floor,
Power is also different in the distribution of hawser everywhere, for example, tension of the hawser at the position close to carriage is generally higher than hawser and exists
Tension at close to the medium position of pulley and hawser, such case are especially apparent in high-rise building, along with high level
Stair of skyscraper itself can also rock frequent occurrence, different when the amplitude rocked is at each layer position, so elevator exists
The male character types in Chinese operas, usu. referring tov the bearded character rotation is not only changed in operational process, but also between each floor, can also there is the change of different small angular speed
Change.In order to maintain the ride experience of stability and passenger of the elevator during whole service, elevator device can be for difference
Floor section objective reality different angular speed, so that elevator is kept different velocity and acceleration to be corresponding to it.However
In the prior art, corresponding technological means is not taken to be monitored based on the minor change of the angular speed of this elevator,
In order to more accurately be monitored to elevator operation, the embodiment of the present invention is by the gyroscope in intelligent terminal come to elevator
Angular speed obtained.Specifically, according to three axis value X, Y, Z of gyroscope, as intelligent terminal coordinate X/Y and terrestrial coordinates X/
When Y is overlapped, intelligent terminal is a around the angle that Z axis rotate, value range for [0,2*PI), rotate counterclockwise and be positive；When intelligent end
When sitting up straight mark Y/Z and terrestrial coordinates Y/Z and being overlapped, intelligent terminal is b around the angle that X-axis rotate, value range for [- 1*PI, PI),
Top is positive towards earth surface rotation, it is of course also possible to be positive towards user；When intelligent terminal coordinate X/Z and the earth are sat
When marking X/Z and being overlapped, intelligent terminal is g around the angle that Y-axis rotate, value range for [- 1*PI/2, PI/2), the right is towards the earth
Surface pivots are positive, and the current athletic posture situation of change of intelligent terminal are judged as in this way, for example, its angular speed.Furthermore it can
The parameters such as acceleration and the speed of elevator are calculated by the accelerometer in intelligent terminal, elevator starts previously measured acceleration
Degree is initial value, and acceleration when elevator is run cuts initial value and obtains acceleration change value, the acceleration on three directions X, Y, Z into
Row be added be squared and, then opening radical sign again both can be obtained acceleration absolute value, then obtain instantaneous velocity by integral operation,
The measured value of the displacement in an available direction is integrated again.Operating status and normal operation shape when for Lift out of order
State compares, and operation when can obtain the operating parameter and normal operation when operation troubles occurs every time for the elevator is joined
The change rate of number, operating parameter when by the generation operation troubles establishes the first Gaussian Profile, for example, being filtered according to Kalman
The speed of elevator and position are set as two variables by wave principle, speed and position be it is relevant, a possibility that position, depends on working as
Preceding speed, then can be used current operating conditions (K-1 moment), to predict next operating status (K moment), can to it is all can
The state change of energy is predicted, and provides the first Gaussian Profile, is indicated with a matrix, and since the direction of elevator is fixed
, then fixed elevator direction can be added in predictive equation and be modified to prediction result；After obtaining the first Gaussian Profile,
The actual measurement of operating parameter when can be according to the generation operation troubles surveys (sensing data) and establishes the second Gaussian Profile,
Two first Gaussian Profiles with different mean values and variance can be multiplied with the second Gaussian Profile again, obtaining one has
The Gaussian Profile of independent mean value and variance to get arrive first Gaussian Profile and second Gaussian Profile lap,
The mean value of part will be fallen again as the optimal estimation of operating parameter when elevator generation operation troubles；Using above-mentioned identical
The optimal estimation that the operating parameter when elevator operates normally can be obtained in calculation specifically can pass through the normal fortune
The change rate of operating parameter when row establishes third Gaussian Profile, and the practical survey of operating parameter when according to the normal operation
Magnitude establishes the 4th Gaussian Profile, and the third Gaussian Profile is multiplied with the 4th Gaussian Profile, obtains the third Gauss point
The lap of cloth and the 4th Gaussian Profile, the optimal estimation of operating parameter when as the generation operation troubles.?
Obtain the optimal of the operating parameter when optimal estimation and normal operation of operating parameter when operation troubles occurs for the elevator
After estimation, the related data under the various states of the elevator can be accumulated as big data, based on speed, acceleration, angle speed
The situation of change of degree and position, establishes Related Mathematical Models using probability theory, can show that event occurs for elevator by the mathematical model
Difference between the operating parameter of operating status when barrier and the operating parameter of normal operating condition can be set accordingly according to difference
The value of the threshold value of operating parameter, the operating parameter that operating parameter when the elevator is run deviates normal operating condition reaches threshold value
When, capable of emitting preparatory trouble hunting alarm.When in this step, detecting that the elevator currently runs shape by intelligent terminal
The operating parameter of state deviates the normal operating condition of the elevator, then this process goes to S102.
S102: deviate the journey of the normal operating condition of the elevator according to the operating parameter of the elevator current operating conditions
Whether degree reaches threshold value, judges whether the elevator current operating conditions are abnormal.
In embodiments of the present invention, the threshold value includes angular speed threshold value, acceleration rate threshold and threshold speed, it is corresponding described in
The different angular speed that the current operating conditions of elevator are included have different acceleration rate thresholds and different threshold speeds, that is, work as
When the value of elevator ditch speed deviations elevator normal operating condition is not up to angular speed threshold value, elevator is run in different floor sections
When each angular speed correspond to different acceleration rate threshold and threshold speed.This is because, as described above, in order to maintain electricity
The ride experience of stability and passenger of the ladder during whole service, elevator device can be objective for different floor sections
Existing different angular speed makes elevator keep different velocity and acceleration to be corresponding to it.Specifically, work as in this step
In, it can first judge whether the size of the absolute value of the angular speed of the elevator current operating conditions reaches the angular speed threshold value,
If reaching the angular speed threshold value, it is determined that the elevator current operating conditions are abnormal, if the not up to described angular speed threshold
Value, then can further judge the elevator current operating conditions acceleration or speed deviations described in elevator normal operating condition
Acceleration or the value of speed whether reach the acceleration rate threshold or threshold speed, can further judge that elevator is currently run
The acceleration of the acceleration offset normal operating condition of state it is worth and whether reaches and acceleration threshold corresponding to the angular speed
Value, and judge the speed deviations normal operating condition of elevator current operating conditions acceleration be worth and whether reach and the angle
Threshold speed corresponding to speed.If the acceleration of elevator current operating conditions or the value of speed deviations normal operating condition reach
The acceleration rate threshold or threshold speed then can determine that the elevator current operating conditions are abnormal.If for example, angular speed
Threshold value is 5, when the angular speed under elevator current operating conditions is 1, since acceleration rate threshold corresponding with angular speed 1 is 6, and speed
Spending threshold value is 10, at this time, as long as the value of the acceleration offset elevator normal operating condition under elevator current operating conditions is more than
The value of speed deviations elevator normal operating condition under acceleration rate threshold 6 or elevator current operating conditions is more than threshold speed
When 10, it can be confirmed that elevator is abnormal；When the angular speed under elevator current operating conditions is 3, due to corresponding with angular speed 3
Acceleration rate threshold be 4, threshold speed 7, at this time, as long as the acceleration offset elevator under elevator current operating conditions is normal
The value of operating status is more than the speed deviations elevator normal operating condition under acceleration rate threshold 4 or elevator current operating conditions
Value be more than threshold speed 7 when, can be confirmed that elevator is abnormal.When in this step, judging that the elevator currently runs shape
When state is abnormal, this method process goes to S103.
S103: warning information is sent to monitor terminal by the intelligent terminal.
It specifically, can be by the intelligent terminal by the warning information of the location information comprising the elevator and exception information
It is sent to monitor terminal.Wherein, the location information of elevator can be obtained by the intelligent terminal.Certainly, true by the above method
Determine that early warning can also be transmitted from the holder of the intelligent terminal to elevator service personnel or monitoring center after elevator is abnormal
Information.The warning information such as the location information of the elevator and exception information are sent jointly into monitor terminal, it can be by a large amount of electricity
The related data of ladder under various regimes is accumulated as big data, has done base for the elevator distribution of smart city and condition monitoring situation
Plinth data accumulation, also for elevator under normal operating conditions under abnormal operating condition most have parameter Estimation, threshold calculations with
And the foundation of Related Mathematical Models provides huge sufficient data statistics and operating basis.
In the elevator safety monitoring method that Fig. 1 is provided, elevator can be detected by the intelligent terminal in elevator and currently run
Whether acceleration, speed and the angular speed of state deviate the normal operating condition of elevator, and can be when detecting deviation, according to electricity
Whether the degree that the operating parameter of terraced current operating conditions deviates the operating parameter of the normal operating condition of elevator reaches threshold value, comes
Judge whether elevator current operating conditions are abnormal, it, can be by intelligent terminal to monitor terminal after judging to be abnormal
Send warning information.It is placed on elevator interior due to, needing to buy in the prior art special detector, there are follow-up maintenances and networking
Situation, and also need separately to safeguard when detector itself goes wrong, and the sensing equipment in the embodiment of the present invention is using intelligent hand
Machine can reduce the generation of maintenance and installation question in the prior art.Again because of the generality of smart phone, number collected
According to will be huger, according to machine learning principle, when data are bigger, accuracy also will be higher, and big data early warning will be more accurate.
Furthermore the embodiment of the present invention uses the dual height of predicted value (i.e. change rate) and measured value based on operating parameters such as angular speed
The method that the mode of this distribution acquires optimized parameter estimated value and related different threshold values, can be improved the accurate of operating parameter early warning
Property, and then reduce the incidence of elevator accident.
Referring to Fig. 2, Fig. 2 is the structural block diagram of elevator safety monitoring device provided in an embodiment of the present invention.Such as Fig. 2 institute
Show, the elevator safety monitoring device 20 of the present embodiment includes detection module 201, judgment module 202 and warning module 203, in which:
Detection module 201, the operation for detecting the elevator current operating conditions by the intelligent terminal in elevator are joined
Whether number deviates the normal operating condition of the elevator.Specifically, detection module 201 can first pass through the intelligent terminal in elevator
(for example, smart phone) obtains the operating parameter of the elevator current operating conditions, then judges the elevator current operating conditions
Operating parameter whether deviate the normal operating condition of the elevator.The normal operating condition of the elevator may include normally transporting
The Gaussian Profile or change rate of operating parameter when row.Wherein, the operating parameter mainly includes acceleration, speed and angle speed
Degree.Since elevator is by transmissions such as motor, pulley and hawsers, hawser hangs carriage by extending downwardly at the top of elevator, because
This, when the carriage of elevator is in different floors, i.e., the length difference of the hawser of carriage to elevator when, hawser entirety tension is
Different, and when carriage is located at a certain floor, tension is also different in the distribution of hawser everywhere, for example, hawser is close
Tension at the position of carriage is generally higher than tension of the hawser at the medium position close to pulley and hawser, and such case exists
It is especially apparent in high-rise building, along with stair of high-rise skyscraper itself can also rock frequent occurrence, the amplitude rocked
It is different when at each layer position, so elevator not only changes the male character types in Chinese operas, usu. referring tov the bearded character rotation in the process of running, but also between each floor,
Can also there be the variation of different small angular speed.In order to maintain stability and passenger of the elevator during whole service
Ride experience, elevator device can be directed to the different angular speed of different floor section objective reality, elevator be made to keep different
Velocity and acceleration be corresponding to it.However in the prior art, there is no the minor changes of the angular speed based on this elevator
Corresponding technological means is taken to be monitored, in order to be more accurately monitored to elevator operation, the embodiment of the present invention
The angular speed of elevator is obtained by the gyroscope in intelligent terminal.Specifically, according to three axis value X, Y of gyroscope,
Z, when intelligent terminal coordinate X/Y and terrestrial coordinates X/Y is overlapped, intelligent terminal is a around the angle that Z axis rotates, and value range is
[0,2*PI), it rotates counterclockwise and is positive；When intelligent terminal coordinate Y/Z and terrestrial coordinates Y/Z is overlapped, intelligent terminal is around X-axis
The angle of rotation is b, value range be [- 1*PI, PI), top is positive towards earth surface rotation, it is of course also possible to towards with
Family is positive；When intelligent terminal coordinate X/Z and terrestrial coordinates X/Z is overlapped, intelligent terminal is g, range around the angle that Y-axis rotates
Value for [- 1*PI/2, PI/2), the right towards earth surface rotation be positive, be judged as the current athletic posture of intelligent terminal in this way
Situation of change, for example, its angular speed.Furthermore can be calculated by the accelerometer in intelligent terminal elevator acceleration and
The parameters such as speed, it is initial value that elevator, which starts previously measured acceleration, and acceleration when elevator is run cuts initial value and accelerated
Spend changing value, the acceleration on three directions X, Y, Z be added be squared and, then open radical sign again both acceleration can be obtained and is exhausted
To value, instantaneous velocity then is obtained by integral operation, integrates the measured value of the displacement in an available direction again.For to electricity
Operating status and normal operating condition when ladder breaks down compare, when can obtain the elevator operation troubles occurring every time
Operating parameter and normal operation when operating parameter, the change rate of operating parameter when by the generation operation troubles builds
The speed of elevator and position are set as two variables for example, according to Kalman filter theory by vertical first Gaussian Profile, speed and
Position be it is relevant, depending on current speed a possibility that position, current operating conditions (K-1 moment) then can be used, come
It predicts next operating status (K moment), all possible state change can be predicted, and provide the first Gaussian Profile, used
One matrix expression, and since the direction of elevator is fixed, then fixed elevator direction can be added in predictive equation to pre-
Result is surveyed to be modified；After obtaining the first Gaussian Profile, can according to it is described generation operation troubles when operating parameter reality
Measurement surveys (i.e. sensing data) and establishes the second Gaussian Profile, then can will be two described first with different mean values and variance high
This distribution is multiplied with the second Gaussian Profile, obtains the Gaussian Profile with independent mean value and variance to get arriving described first
As the elevator operation troubles is occurred for the mean value for falling part again by the lap of Gaussian Profile and second Gaussian Profile
When operating parameter optimal estimation；The operation when elevator operates normally can be obtained using above-mentioned identical calculation to join
Third Gaussian Profile is established in several optimal estimations, specifically, the change rate of operating parameter when can be by the normal operation, and
The actual measured value of operating parameter when according to the normal operation establishes the 4th Gaussian Profile, by the third Gaussian Profile with
4th Gaussian Profile is multiplied, and the lap of the third Gaussian Profile Yu the 4th Gaussian Profile is obtained, as the hair
The optimal estimation of operating parameter when raw operation troubles.Operating parameter when obtaining the elevator and operation troubles occurring it is optimal
It, can be by the related data under the various states of the elevator after the optimal estimation of operating parameter when estimation and normal operation
It is accumulated as big data, based on speed, acceleration, angular speed and the situation of change of position, establishes related mathematical modulo using probability theory
Type can obtain the operating parameter of operating status when Lift out of order and the operation of normal operating condition by the mathematical model
Difference between parameter can set the threshold value of corresponding operating parameter according to difference, and operating parameter when the elevator is run deviates just
When the value of the operating parameter of normal operating status reaches threshold value, capable of emitting preparatory trouble hunting alarm.
Judgment module 202, for detecting that the elevator is currently transported by the intelligent terminal in elevator in detection module 201
When the operating parameter of row state deviates the normal operating condition of the elevator, joined according to the operation of the elevator current operating conditions
Whether the degree that number deviates the normal operating condition of the elevator reaches threshold value, judges whether the elevator current operating conditions are sent out
It is raw abnormal.Specifically, the threshold value includes angular speed threshold value, acceleration rate threshold and threshold speed, corresponds to the current of the elevator
The different angular speed that operating status is included have different acceleration rate thresholds and different threshold speeds, i.e., when elevator ditch speed
When the value that degree deviates elevator normal operating condition is not up to angular speed threshold value, each of elevator when different floor sections are run
Angular speed all corresponds to different acceleration rate threshold and threshold speed.This is because, as described above, in order to maintain elevator entirely transporting
The ride experience of stability and passenger during row, elevator device can be directed to the difference of different floor section objective reality
Angular speed, so that elevator is kept different velocity and acceleration to be corresponding to it.Specifically, in this step, can first judge
Whether the size of the absolute value of the angular speed of the elevator current operating conditions reaches the angular speed threshold value, if reaching the angle
Threshold speed, it is determined that the elevator current operating conditions are abnormal, can be further if the not up to described angular speed threshold value
Judge the elevator current operating conditions acceleration or speed deviations described in elevator normal operating condition acceleration or speed
Whether the value of degree reaches the acceleration rate threshold or threshold speed, can further judge the acceleration of elevator current operating conditions
It is worth with deviateing the acceleration of normal operating condition and whether reaches and acceleration rate threshold corresponding to the angular speed, and judgement electricity
Be worth to the acceleration of the speed deviations normal operating condition of terraced current operating conditions whether reach with corresponding to the angular speed
Threshold speed.If the acceleration of elevator current operating conditions or the value of speed deviations normal operating condition reach the acceleration threshold
Value or threshold speed, then can determine that the elevator current operating conditions are abnormal.If working as electricity for example, angular speed threshold value is 5
When angular speed under terraced current operating conditions is 1, since acceleration rate threshold corresponding with angular speed 1 is 6, threshold speed 10,
At this time, as long as the value of the acceleration offset elevator normal operating condition under elevator current operating conditions is more than acceleration rate threshold 6,
Or the value of the speed deviations elevator normal operating condition under elevator current operating conditions be more than threshold speed 10 when, can be confirmed
Elevator is abnormal；When the angular speed under elevator current operating conditions is 3, due to acceleration rate threshold corresponding with angular speed 3
It is 4, threshold speed 7, at this time, as long as the value of the acceleration offset elevator normal operating condition under elevator current operating conditions
Value more than the speed deviations elevator normal operating condition under acceleration rate threshold 4 or elevator current operating conditions is more than speed
When threshold value 7, it can be confirmed that elevator is abnormal.
Warning module 203, for leading to when the judgment module judges that the elevator current operating conditions are abnormal
It crosses the intelligent terminal and sends warning information to monitor terminal.Specifically, warning module 203 can will be wrapped by the intelligent terminal
The warning information of location information and exception information containing the elevator is sent to monitor terminal.Wherein, the location information of elevator, can
It is obtained by the intelligent terminal.It certainly, can also be by the intelligent terminal after determining that elevator is abnormal by the above method
Holder transmit warning information to elevator service personnel or monitoring center.By the location information of the elevator and exception information etc.
Warning information sends jointly to monitor terminal, the related data of a large amount of elevator under various regimes can be accumulated as big data,
It is accumulative to have done basic data for the elevator distribution of smart city and condition monitoring situation, also for elevator under normal operating conditions and
Most there is the foundation of parameter Estimation, threshold calculations and Related Mathematical Models to provide huge sufficient number under abnormal operating condition
According to statistics and operating basis.
