Abstract
The invention relates to an intelligent elevator monitoring method. At least one camera with an overhead view field capable of covering the inside of an elevator car is arranged at the top of the elevator car, a floor of the car is divided into a plurality of lattice areas, a pressure sensor is mounted below each lattice area of the floor, and both the camera and the pressure sensor are in communication connection with a background host. By the intelligent elevator monitoring method, an intelligent elevator monitoring system can be used for automatically analyzing video contents, an alarm can be automatically given when a warning condition happens, and the burden of manual monitoring is relieved.
Description
Technical field
The present invention relates to elevator safety-security area, and in particular to a kind of elevator intelligent monitoring method.
Background technology
It is fitted with elevator substantially in high-rise, the life that elevator gives people brings huge facility.But
Because elevator is operationally in closed state, lawless person is also given many chances, news media often report one
A little elevator incidents of violence, in particular for the behavior of exerting violence of child and women, have impact on the stable and united of society.
For the boarding security for improving passenger, people generally install camera in elevator, but if to realize reality
When monitor, being necessarily required to video of a large amount of monitoring personnels to being taken the photograph by camera carries out real-time manual monitoring, when there is alert
Realtime Alerts take measure to stop, and the realization but this gets up has great difficulty.Therefore existing safety defense monitoring system can only rise
To in the effect for providing evidence afterwards.
The content of the invention
The technical problem to be solved in the present invention is：Proposition is a kind of can be with the elevator intelligent monitoring method of automatic alarm.
The present invention is that the technical scheme for solving above-mentioned technical problem proposition is：A kind of elevator intelligent monitoring method, the electricity
At least one tower visibility is provided with the top of terraced car can cover video camera inside the lift car, the floor of the car
Multiple trellis regions are divided into, a pressure sensor, the video camera and pressure are installed under the floor in each trellis region
Sensor is set up with background host computer and is communicated to connect；
The method comprising the steps of, following steps are carried out by the background host computer：
A, real-time processing is carried out to taking the photograph video by video camera, extract corresponding top profile with each passenger simultaneously
The top profile is numbered respectively；Gather at each passenger institute standing place the pressure value in trellis region and draw real-time
Pressure value curve；
B, the top profile operating path to different numberings carry out real-time tracking, and calculate the different numberings in real time
Minimum distance between the contour edge of top；
C, when the minimum distance is equal to zero, the fluctuation range of the real-time pressure value curve is analyzed, if the pressure
When the fluctuation range of force value curve is more than pre-set interval, there is one-level alert in the background host computer identification；
D, the background host computer outwardly send alert cue.
Further, be also equipped with pickup microphone in the lift car, the pickup microphone also with it is described after
Platform main frame sets up communication connection；
Also include step e between step c and step d：Platform main frame identification in the rear occurs after one-level alert,
The background host computer is analyzed to the decibel value of voice signal in car, when the decibel value be more than preset value when, it is described after
The one-level alert is risen to superfine alert by platform main frame.
A kind of elevator intelligent monitoring system, it is characterised in that：Elevator car roof and vertical view are arranged on including at least one
The visual field can cover video camera inside the lift car, multiple underfloor pressure sensors installed in the car and after
Platform main frame, the video camera and pressure sensor are set up with background host computer and are communicated to connect.
Further, also include be arranged on lift car in pickup microphone, the pickup microphone also with it is described after
Platform main frame sets up communication connection.
Further, it is provided with talkback unit in the car.
The invention has the beneficial effects as follows：
Voluntarily video content can be entered by elevator intelligent monitoring system by the elevator intelligent monitoring method in the present invention
Row analysis, it is capable of automatic alarm when there is alert, alleviate manual supervisory burden.
Specific embodiment
Embodiment one
A kind of elevator intelligent monitoring system, including one be arranged on elevator car roof and tower visibility can cover elevator car
Video camera, multiple underfloor pressure sensors and background host computer, video camera and pressure sensing installed in car inside railway carriage or compartment
Device is set up with background host computer and is communicated to connect.
The floor of car is first divided into multiple trellis regions by pressure sensor when mounted, on the ground in each trellis region
One pressure sensor is installed under plate,
Can be used as preferably：Also include be arranged on lift car in pickup microphone, pickup microphone also with backstage
Main frame sets up communication connection.
Can be used as preferably：Talkback unit is provided with the car.
Embodiment two
A kind of elevator intelligent monitoring method, realizes, method is comprised the following steps by the hardware in the system of embodiment one, with
Lower step is carried out by background host computer：
A, real-time processing is carried out to taking the photograph video by video camera, extract corresponding top profile with each passenger simultaneously
Top profile is numbered respectively.Can be extracted by background subtraction when the top profile of passenger is extracted, will not had in car
Real-time video picture and background frame are carried out subtraction process by picture during passenger as background frame by computer software,
Obtain the top profile of passenger.Background subtraction is that prior art no longer more to be stated.
Gather at each passenger institute standing place the pressure value in trellis region and draw real-time pressure value curve.
B, the top profile operating path to different numberings carry out real-time tracking, and calculate the top of different numberings in real time
Minimum distance between contouring edge；Can be extracted by frame differential method in real-time tracking and be calculated, frame differential method
State for prior art no longer more.
C, when minimum distance be equal to zero when, analyze real-time pressure value curve fluctuation range, if the ripple of pressure value curve
When dynamic scope is more than pre-set interval, there is one-level alert in background host computer identification；
D, background host computer outwardly send alert cue.
In order to reduce rate of false alarm, can be used as preferably：Also include step e between step c and step d：In backstage master
Machine identification occurs after one-level alert, and background host computer is analyzed to the decibel value of voice signal in car, when decibel value is more than pre-
If during value, one-level alert is risen to superfine alert by background host computer.
The present invention is not limited to above-described embodiment, and the technical scheme of above-mentioned each embodiment of the present invention can intersect each other
Combination forms new technical scheme, the technical scheme that in addition all employing equivalents are formed, and all falls within the protection of application claims
In the range of.
