Description
Technical field
This utility model relates to a kind of elevator car safety, particularly relates to a kind of elevator warning system.
Background technology
Elevator has an accident again and again, and elevator door is opened when, lift car does not runs to current layer,
Cause personnel to step on the situation of sky injures and deaths, if this situation in fact take that the people of elevator somewhat notes would not
Step on the danger of sky, take the dispersion of the attention of the people of elevator, cause the generation of tragedy.If energy
When lift car staggered floor, remind user in time, be just avoided that the generation of tragedy.
Utility model content
This utility model aims to provide a kind of elevator warning system, when elevator staggered floor can in time, have
User is reminded on effect ground.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
Elevator warning system disclosed in this utility model, including infrared sensor of the human body, DC source, institute
The outfan stating infrared sensor of the human body connects one end of resistance R1, and the other end of described resistance R1 connects
The base stage of NPN audion Q1, the colelctor electrode of described NPN audion Q1 connects one end and the report of resistance R2
Alert device, the other end connection DC source of described resistance R2, the grounded emitter of NPN audion Q1,
Described DC source is that infrared sensor of the human body, alarm are powered.
When mounted, infrared sensor of the human body, alarm are arranged in elevator just to electricity this utility model
Ladder door side, infrared sensor of the human body towards facing elevator door central point.
Operation principle of the present utility model: if elevator door opens and lift car is not at current layer, then
Infrared sensor of the human body can sense people, thus after driving NPN audion Q1, NPN audion Q1 conducting
Alarm equipment alarm, reminds the user that elevator run-time error, it is to avoid user enters.
Preferably, described alarm includes buzzer.
Preferably, described alarm is audible-visual annunciator.
Preferably, described alarm includes red-light LED.
This utility model can in time, effectively remind user, simple in construction, effect when elevator staggered floor
The best, and do not affected by apparatus for controlling elevator.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with attached
Figure, is further elaborated to this utility model.
As it is shown in figure 1, elevator warning system disclosed in this utility model, including infrared sensor of the human body,
DC source, the outfan of infrared sensor of the human body connects one end of resistance R1, the other end of resistance R1
Connect the base stage of NPN audion Q1, the colelctor electrode of NPN audion Q1 connect resistance R2 one end and
Alarm, the other end connection DC source of resistance R2, the grounded emitter of NPN audion Q1, directly
Stream power supply is that infrared sensor of the human body, alarm are powered.Alarm can use red-light LED, it is possible to uses
Buzzer or audible-visual annunciator.
Certainly, this utility model also can have other various embodiments, without departing substantially from this utility model spirit and
In the case of its essence, those of ordinary skill in the art can according to this utility model make various accordingly
Change and deformation, but these change accordingly and deformation all should belong to the claim appended by this utility model
Protection domain.
