S101: according to preset acceleration Rule of judgment, judge whether the acceleration signal of the lift car obtained occurs
It is abnormal；According to preset sound Rule of judgment, judge whether the voice signal of the lift car obtained is abnormal.
When specific implementation, acceleration signal be can be through accelerometer acquisition, for example, it may be using adding
Velocity sensor within a preset time period, obtains voltage signal, and voltage signal is carried out to certain pretreatment, for example, plus
Velocity sensor itself has a sensitivity, and wherein sensitivity indicates the corresponding relationship between voltage and acceleration, according to spirit
Voltage signal can be converted to acceleration signal by sensitivity.Since the process run in elevator is in the horizontal direction at that may deposit
It shakes, it is therefore possible to use 3-axis acceleration sensor obtains the multiple directions in lift car operational process along the horizontal plane

The Y direction of acceleration transducer.
As an example, being standardized to acceleration signal includes: the history acceleration letter for calculating Z-direction
Number average value, as the standard value of acceleration transducer in Z-direction, behind collected Z-direction acceleration signal
It is both needed to subtract the standard value of acceleration transducer in Z-direction, obtains normal acceleration signal.
In other embodiments, the average value that acceleration signal in such as X-direction can be calculated, using the average value as
The average value of acceleration transducer in X-direction, behind the acceleration signal of collected X-direction subtract in the X-direction
The average value of acceleration transducer.
In other embodiments, the average value that acceleration signal in such as Y direction can be calculated, using the average value as
The average value of acceleration transducer in Y direction, behind the acceleration signal of collected Y direction subtract in the Y direction

It should be noted that acceleration transducer can acquire the electricity in the preset time period of lift car in the process of running
Press signal, voltage signal be converted into acceleration signal, and calculate the average value of the acceleration value in acceleration signal when
Wait, can be using intercepted in preset time period starting point to some time point acceleration signal as history acceleration signal,
And then usage history acceleration signal calculate average value, and the acceleration signal of remainder then as monitoring elevator whether failure
Acceleration signal.
In embodiments of the present invention, the acceleration signal curve of all directions of 3-axis acceleration sensor acquisition is respectively
It is fluctuated up and down around the average value of all directions, but by standardization, normal acceleration signature tune can be made
Line fluctuates up and down around axis, for example, to the normal acceleration signal curve after the acceleration signal standardization of X-direction
It is fluctuated up and down around X-axis (i.e. y=0).The embodiment of the present invention, can be further by being standardized to acceleration signal
Improve the speed of service for the lift car being calculated.
As an example, a series of filtering algorithms (for example, Kalman filtering algorithm etc.) be can use respectively to first
The normal acceleration signal of direction and second direction is filtered, to remove the noise in normal acceleration signal, such as
Ambient noise, ambient noise etc. obtain the Kalman filtering signal of first direction and second direction.
Wherein, a representative instance of Kalman filtering algorithm be from one group it is limited, comprising noise, to object space
Observation sequence (there may be deviations) in predict the coordinate position and speed of object.
As an example, in order to further decrease error, a series of filtering algorithms be can use (for example, mechanical filtering
Deng) threshold determination is carried out to the value (i.e. the Kalman filtering signal of first direction and second direction) after Kalman filtering, such as
Return-to-zero is carried out to the Kalman filtering signal for being less than preset threshold, to obtain acceleration signal, at this point, acceleration signal is
Do not have noisy acceleration signal.
Therefore, by utilizing Kalman filtering algorithm and mechanical filtering algorithm etc., to first direction and second party
To normal acceleration signal be repeatedly filtered, the noise in normal acceleration signal can be removed, to obtain carriage
There is no noise and causes the acceleration signal of error by the factor of sensor itself.
S102: if at least one in acceleration signal and voice signal is abnormal, signal is detected according to the floor of acquisition

System.In some embodiments, photoelectric sensor includes: trough type photoelectric sensor, correlation type photoelectric sensor, reflective type photoelectricity
Switch and diffusion reflection pattern optoelectronic switch.
For example, can use trough type photoelectric sensor in the aforementioned embodiment, wherein trough type photoelectric sensor is a light
What transmitter and a receiver were mounted in the two sides of a slot Face to face is flute profile photoelectricity.Photophore can issue infrared light or can
Light-exposed, optical receiver can receive light in without hindrance situation.But when object to be detected passes through from slot, light is blocked, and photoelectricity is opened
Pass just acts.A switch control signal is exported, load current is switched off or on, to complete a control action.Flute profile is opened
The detecting distance of pass is because generally there was only several centimetres by integrally-built limitation.
For example, when photoelectric sensor is blocked by baffle, the output of photoelectric sensor is high level, when photoelectric sensor not
When being blocked by baffle, the output of photoelectric sensor is low level.For example, indicating photoelectric transfer when photoelectric detecting signal output is 1
Sensor is blocked by baffle, when photoelectric detecting signal output is 0, indicates that photoelectric sensor is not blocked by baffle.
Next, being exported according to the photoelectric detecting signal of the speed signal of elevator and elevator, so that it may judge elevator faults
Place destination.
S103: if the number that destination is abnormal is greater than preset value, triggering alarming mechanism is determined.
When specific implementation, it is abnormal signal each time, can all record and be abnormal the corresponding target building of signal
Layer, when the number that the destination is abnormal signal is more than preset value, such as more than 3 times, then can set out alarming mechanism, e.g.,
Acoustic-optic alarm can be set in elevator monitoring room, to remind staff to overhaul elevator in time.
