Abstract
The utility model relates to an escalator monitoring device which includes a hand strap, a hood cover, a skirt board and a background restraining sensor, the background restraining sensor is set in the hood cover below the hand strap, or the skirt board, or the hood cover outside; the background restraining sensor is a mechanism type sensor composed of a component for receiving object light and a component for receiving background light or an electronic type sensor composed of a position sensor element. The escalator monitoring device has advantages that the background restraining sensor can not be effected by irradiated passenger or the object material and color which leads to be undetected, at the same time, reduces the effect caused by the object reflex besides the object to minimum; and also can be used as a monitoring device in an entrance area of automatic footpath.
Description
Technical field
The utility model relates to a kind of escalator monitor unit.
Background technology
In the energy-saving run control setup of known escalator, when no passenger uses, escalator is in and stops or the energy-saving run state, as passenger during near escalator, trigger a signal during for example by the photoelectricity fence and offer the escalator drive system, staircase is moved according to normal speed.After passing through certain ticket reserving time, guaranteeing that last passenger leaves escalator, drive system stops the operation of escalator or makes it be in the energy-saving run state.A kind of opto-electronic pickup with projector and receptor on the cover cap below the handrail that is installed in is provided in patent ER0847956, this sensor monitors the entrance area of escalator, its groundwork principle is to utilize projector emission infrared light, shine the passenger's goods object that is about to enter escalator, be reflected, receive and amplification by receptor, thereby export a signal to the escalator drive system.Because the reflectivity of infrared light is subjected to factor affecting such as the material, color of shone thing, so, can not guarantee that passenger that all are irradiated to or the infrared light that object reflected are enough to make orders about receptor an output signal is provided, and that is to say and can not guarantee that all enter the passenger or the object that are monitored the zone and can effectively be monitored.
The utility model content
The purpose of this utility model provides a kind of escalator monitor unit, adopt projector emission infrared light to overcome existing escalator monitor unit, shine object, be reflected, the principle that receives and amplify by receptor, but the reflectivity of infrared light is subjected to the deficiency of factor affecting such as the material, color of shone thing.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of escalator monitor unit comprises that handrail, cover cap, skirtboard and background suppress sensor, and in the cover cap of described handrail below or on the skirtboard or the cover cap outside is provided with background and suppresses sensor; Described background suppresses the diffuser reflection type sensor that sensor is receiving target object light element and the electronic type bias light inhibit feature that diffuses electric transducer or be made up of a position sensor that receives mechanical type bias light inhibit feature that background lighting element forms.
The beneficial effects of the utility model are: background suppresses factor affecting such as material that sensor can not be subjected to illuminated passenger or object, color and causes omission, and simultaneously, the influence that will be caused by the object reflected light outside the target drops to minimum; Also can be used as the monitor unit of the entrance area of moving sidewalk.
Description of drawings
Fig. 1 is the structural representation of the described escalator monitor unit of the utility model embodiment.
Among the figure:
1, handrail; 2, cover cap; 3, skirtboard; 4, the cover cap outside; 5, background suppresses sensor.
The specific embodiment
As shown in Figure 1, the described escalator monitor unit of the utility model embodiment comprises that handrail 1, cover cap 2, skirtboard 3 and background suppress sensor 5, and in the cover cap 2 of described handrail 1 below or on the skirtboard 3 or cover cap outside 4 is provided with background and suppresses sensor 5; Described background suppresses sensor 5 for receiving target object light element with receive the diffuser reflection type sensor of the electronic type bias light inhibit feature that diffuses electric transducer or be made up of a position sensor (PSD) of mechanical type bias light inhibit feature that background lighting element forms.
During concrete the use, adopt the mechanical type background to suppress sensor, when the catoptrical intensity on the target receptor surpasses reflected light on the bias light receptor, just can detect target, produce output signal; Adopt the electronic type background to suppress sensor, illuminator sends Ray Of Light, and beam reflection is returned, the light that reflects from object and two diverse locations that reach position sensor from the light that background object reflects; Background suppresses sensor and compares reaching this light of 2 of position sensor, and this signal and the numerical value of setting are in advance compared, thus the state of decision output.
Claims (1)
1, a kind of escalator monitor unit comprises handrail (1), cover cap (2), skirtboard (3), it is characterized in that: the cover cap (2) of described handrail (1) below is interior or skirtboard (3) is gone up or the cover cap outside (4) is provided with background inhibition sensor (5); Described background suppresses sensor (5) for receiving target object light element with receive the diffuser reflection type sensor of the electronic type bias light inhibit feature that diffuses electric transducer or be made up of a position sensor of mechanical type bias light inhibit feature that background lighting element forms.
