Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Example (b):
as shown in fig. 1 and 2, the utility model provides a hierarchical warning device of elevator intelligent monitoring, including central processing unit 13, image recognition treater 12, elevator controller 15, set up respectively in the first camera 4 at 8 inner wall tops of car, first smoke transducer 5, second camera 6, second smoke transducer 7, loudspeaker 10 and warning light 9 to and set up in 2 inboard pressure sensor 1 of lift-cabin door, set up in the infrared inductor 11 of 8 inner wall sides of car and set up in the indoor surveillance center attention device 14 of security.
The first camera 4 and the second camera 6 are respectively connected with a central processing unit 13 through an image recognition processor 12, the first smoke sensor 5, the second smoke sensor 7, the loudspeaker 10, the warning lamp 9, the pressure sensor 1, the infrared sensor 11 and the elevator controller 15 are respectively connected with the central processing unit 13, and the monitoring center warning indicator 14 is in communication connection with the central processing unit 13.
Wherein, first camera 4 and first smoke transducer 5 are installed in 8 inner wall tops of car through same mount pad 3, second camera 6 and second smoke transducer 7 are installed in 8 inner wall tops of car through same mount pad 3, warning light 9 and public address loudspeaker 10 are installed in 8 inner wall tops of car through same mount pad 3, and first camera 4 and second camera 6 are installed respectively in two diagonal positions at 8 inner wall tops of car, and public address loudspeaker 10 is installed in the remaining arbitrary corner at 8 inner wall tops of car.
The height range of the pressure sensor 1 is 0.5 m-1.8 m, the width range is the same as the width of the elevator door 2, the infrared sensor 11 is arranged on the side surface of the inner wall of the elevator car 8 close to the elevator door 2, and the height is 1.2 m.
The central processing unit 13 may employ an ARM microprocessor LPC11C 14.
The utility model discloses a hierarchical warning device of elevator intelligent monitoring can discern elevator passenger's dangerous action automatically to adopt hierarchical warning system according to the danger degree. The first level of the graded warning is automatic warning, namely voice prompt in the car; the second level is manual intervention, namely warning of a monitoring center; the III level is direct control, namely the elevator is controlled not to be started or to be stopped at the near flat floor, and the method specifically comprises the following steps:
level I automatic warning: a voice prompt is sent out in the elevator car through the loudspeaker 10 to remind passengers of paying attention;
stage II manual intervention: an alarm signal is sent out through the alarm 14 of the monitoring center to prompt monitoring center personnel to pay attention and process in time;
stage iii direct control: when an extremely dangerous situation is found, the elevator is controlled by the elevator controller 15 not to be started or to be stopped in a near flat layer, so that dangerous behaviors can be effectively stopped, and more serious consequences are avoided.
As shown in fig. 3, the image recognition processor 12 recognizes images collected by the two cameras, recognizes four unsafe elevator riding behaviors, determines whether there is a behavior of leaning against a car door, an intentional door, a child riding an elevator alone or smoking in a car, and if it is determined that the behavior does not belong to a dangerous elevator riding behavior, the elevator operates normally; and if the dangerous behavior belongs to one of dangerous elevator riding behaviors, entering a dangerous behavior processing flow.
As shown in fig. 4, in the dangerous behavior processing flow, the first smoke sensor 5, the second smoke sensor 7, the pressure sensor 1, and the infrared sensor 11 are combined to perform comprehensive determination. If the first smoke sensor 5 and the second smoke sensor 7 alarm at the same time, the combination of the image recognition result can be determined as smoking in the passenger elevator car; if the pressure sensor 1 gives an alarm, the passenger can be determined to lean against the car door by combining the image recognition result; if the infrared sensor 11 gives an alarm, the child can be identified as singly taking the elevator by combining the image identification result; if no alarm is given, the combination of the image recognition result can be determined as the intentional door stop. Carry out dual judgement to dangerous behavior of taking advantage of the ladder, improve the accuracy of judgement, simultaneously, to different dangerous behaviors, the mode that dangerous behavior handled is also different:
for the behavior of leaning against the car door, a voice prompt is carried out by a loudspeaker 10 in the car to prompt passengers to avoid stopping the door until the alarm is relieved, and meanwhile, if the warning lamp 9 is installed, the warning lamp 9 can be synchronously started to warn in two aspects of sound and light;
the behavior of intentionally blocking the door is warned in two aspects, namely, a loudspeaker 10 in the car is combined with a warning lamp 9 to give a voice prompt to prompt passengers to avoid blocking the door until the alarm is relieved; secondly, after the voice prompt is invalid, a warning signal is sent out through the monitoring center warning indicator 14 to inform security monitoring personnel to carry out human intervention processing at the elevator when necessary;
for the behavior of the children taking the elevator independently, two aspects of warning are carried out, namely, a voice prompt is carried out by combining a loudspeaker 10 in the elevator car with a warning lamp 9 to prompt the children not to take the elevator independently; secondly, an instruction is sent to the elevator controller 15 to forbid the elevator from starting, and meanwhile, the elevator door keeps an open state;
for the smoking behavior in the elevator, two-aspect warning is carried out, firstly, a voice prompt is carried out by combining a loudspeaker 10 in the elevator car with a warning lamp 9 to prompt passengers not to smoke; secondly, after people in the car are monitored to smoke or fire occurs, an instruction is sent to the elevator controller 15 to control the elevator to directly stop and open the door nearby the leveling floor, so that smoke can be evacuated or fire can be extinguished and disaster relief can be realized conveniently.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
