Big country is used in China's conduct elevator first in the world, by the end of the year 2010, is reaching 162.8 ten thousand with the elevator sum, calculates with every average electricity consumption every day 80 degree of elevator, and annual power consumption will reach 46,900,000,000 degree.According to statistics, during the elevator No Load Start consumption of current be when normally moving 4-5 doubly; Loading will be higher when starting, and can reach 7-9 doubly.
The main mode of existing elevator dispatching control system is: whether the other uplink and downlink button of each floor door of elevator detects in elevator control center has calling, if there is calling then to confirm the relation between elevator current location and the calling floor:
When elevator was in halted state, then directly response should be called out; When the position of destination is all consistent with the current service direction of elevator with call direction (the descending service of its following floor call when elevator is descending, the up service of its above floor call during ascending for elevator), then also directly response should calling for elevator.After response should be called out, elevator moved to destination, and up to being about to arrive destination, brake snub, elevator arrive destination service station layer, and after opening the door, close the door, restarting, this calls out cancellation automatically.When the position of destination or call direction and the current service direction of elevator were inconsistent, then elevator was ignored this calling, and when having treated the elevator inverted running, if this calls out as yet cancellation, then response should be called out.If a plurality of elevators are arranged, then respond this calling near the elevator of destination by current.
This mode can satisfy the normal floor demand up and down of elevator passenger; But under this mode; As long as the elevator uplink and downlink button of service floor is pressed, no matter whether this floor also has the passenger to wait for is taken, and elevator all can be made response to it; And in this floor stagnation, waiting Passengen gets into.But during real-world operation, but through regular meeting occur the passenger by the uplink and downlink button do not wait for that situation about taking takes place.Cause elevator that useless stagnation usually takes place, wasted passenger's in the cage time, reduced the operating efficiency of elevator; Also increased simultaneously frequency of utilization and the drag thereof of elevator, the number of times that acceleration starts, wasted energy; And quickened the loss of each parts of elevator operational system, reduced elevator safety property and service life.
Simultaneously, if peak load conditions on and off duty, passengers quantity is very big, has only an elevator response to call out at every turn, and it is too of a specified duration to make that other passengers wait for; Call out if dispatch all elevator responses, so, under the few situation of patronage, certainly will cause the mass energy waste.
Summary of the invention
The purpose of this invention is to provide a kind of elevator energy-saving dispatch control method based on the binocular vision occupant detection, this kind method can improve the operating efficiency of elevator, reduces the energy consumption of elevator, improves the safety and the service life of elevator.
The present invention realizes that the technical scheme that its goal of the invention adopts is: a kind of elevator energy-saving dispatch control method based on the binocular vision occupant detection may further comprise the steps:
A, call information read and graphicinformation is taked
2 video frequency pick-up heads that sampling frequency is identical are installed near each floor layer door of elevator; Elevator control center detects the information of each floor layer door button in real time; The calling floor that detected floor button is pressed; These cameras of calling out floor of elevator control center control start, near the graphicinformation the acquisition layer door, and with the graphicinformation sending information image processing module that collects;
B, occupant detection
Image information processing module adopts the Harr algorithm in the OpenCV software to carry out passenger people's face coupling and detect to the graphicinformation of the calling floor that receives, detects the passenger whether the respective call floor has wait, and send elevator control center with this testing result;
C, elevator traffic control
C1, if testing result show Calls floor has the passenger to wait for, then deployment position is recently and stop or elevator that service direction is identical with call direction responds this floor in elevator control center; Simultaneously, the detection of step B is carried out accomplishing the response to this floor until elevator all the time, carries out the operation of step C2 when perhaps testing result shows no waiting Passengen;
C2, if the testing result show Calls floor of step B has the passenger to be waited for, then the cancellation of elevator control center is extinguished the work that stops its camera simultaneously to the response of this floor and with its floor button lamp.
Compared with prior art, income effect of the present invention is:
One, elevator energy-saving dispatch control method of the present invention; Video image through video frequency pick-up head picked-up marquis ladder zone; And marquis ladder video image is detected processing by image information processing module; Judge marquis ladder zone whether the someone waits for and take elevator,, then cancel the call of this floor automatically if unmanned the wait taken.Avoid the normal frequent useless stagnation that occurs in the existing elevator dispatching control method, shortened the riding time of passenger in elevator, improved the running velocity of elevator.
Two, when avoiding useless stagnation, reducing the time of run of elevator; Frequency of utilization and the drag thereof of elevator, the number of times that acceleration starts have also been significantly reduced; Both energy savings had also reduced the loss of each parts of elevator operational system, had improved elevator safety property and service life.
Three, dual camera carries out IMAQ to marquis's ladder zone, has avoided the image blind area, just can be detected as long as can guarantee the passenger that has in marquis's ladder zone, avoids the erroneous judgement maloperation of elevator control center, guarantees the normal operation of elevator.
Also detect the quantity of the waiting Passengen of calling out floor in the occupant detection of above-mentioned steps B, the waiting Passengen that whether can carry the calling floor also according to the current load carrying ability of the elevator of call accepted floor response, calculates in elevator control center among the step C1; If result of calculation shows and can not carry waiting Passengen, then elevator control center deployment position is time near stops or second, third elevator that service direction is identical with call direction responds the calling of this calling floor.
Like this, call out the waiting Passengen quantity of floor and the elevator quantity Matching of response scheduling, both avoided passenger's wait as long for, further reduced invalid operation and the brake and the number of starts of elevator again, reduce the waste of energy.
Below in conjunction with concrete embodiment the present invention is done further detailed explanation.
