Definitions
- the invention relates to a device for vestibule monitoring for Escalators and moving walks to control the drive.
- the drive In known controls for escalators, the drive is at a unused escalator turned off. Approaching passengers of the Escalator, as is the case when passing through a light barrier a pulse is triggered and the drive is switched on. After expiration of a given time, at the earliest after leaving the last Passenger of the escalator, the drive is switched off again.
- the light barrier of the Escalator distanced arranged on separate columns. This requires an additional and unnecessary material and installation costs. Furthermore, a passenger is not necessarily through the light barrier directed. A person who does not know the control system and the Standing escalator approaching from the side, can bypass the Photoelectric enter the escalator without this is turned on. This can be the detrimental impression of a broken or unreliable one To raise an escalator.
- EP 0 621 225 a display and information device become known for an escalator, which is installed in the balustrade.
- This panel-like device is detachably connected to the balustrade.
- This device contains several components, such as light barriers, Display elements etc.
- the patent EP 0847956 shows in the field of handrail deflection arranged light sensors with transmitters and receivers, which the monitor entire entrance hall of the escalator.
- This device is inconspicuous, but still visible and therefore not perfect vandal-proof.
- these light sensors are from Weather influences are misdirected and e.g. at direct Sunlight radiation triggered.
- Such sensors also need big and expensive amplifier and evaluation electronics and can not the Recognize the direction of a movement.
- the persons, e.g. the escalator approach and those who leave the escalator will be the same treated. With parallel installation of escalators, it often happens that outgoing persons erroneously the other escalator to Initiate starting.
- the invention is based on the object an anteroom monitoring for Escalators for controlling the drive of the type mentioned to propose, which does not have the aforementioned disadvantages and on simple way of early detection of passengers allows which is not misguided by weather influences, which completely invisible, cheaper and more compact and which the direction recognizes a movement.
- the handrail deflection sensors In the area of the handrail deflection sensors are arranged, which monitor the entrance area of the escalator and which for electromagnetic waves with wavelength longer than 100 microns sensitive are. This wavelength range is outside the light and Infrared region of the electromagnetic spectrum.
- the advantages achieved by the invention are therefore essentially to see that the sensors are not affected by the weather can be misdirected, e.g. Sunlight, fog, artificial Lighting, heat radiation.
- the sensors for the user completely invisibly hidden or dissimulated may be because they are e.g. be covered by a plastic cap can.
- a plastic cap can be the optical electromagnetic Waves stop, but not with the electromagnetic waves Wavelength longer than 100 ⁇ m. This will make the whole escalator a lot vandal-proof.
- the escalator control print can become smaller, and cheaper because no electronic evaluation and no amplifier for the new monitoring device needed in this wavelength range becomes.
- a direction detection is in the inventive Monitoring device by the principle of evaluation of the Doppler effect possible. It offers the advantage that only persons be recognized, which go to the escalator and not such as the Leave the escalator, or just brush the shaft cone or pass through. This is a big advantage in parallel installation of Escalators. There it often happens that outgoing persons erroneously cause the other escalator to start.
- sensors on both sides of the escalator attached so that the shaft cone is symmetrical with respect to the escalator and the recognition of people is performed more precisely and accurately.
- the sensors are designed as high-frequency sensors, i.e. sensitive to electromagnetic wavelengths shorter than 1 m. In In this wavelength range, the accuracy of the person recognition maximized.
- FIG. 4 shows a detailed view of a second embodiment.
- the Escalator 1 has a number of stages 2, which are endless encircling step band between two Balustradensockeln 3 embedded are.
- a balustrade 4 is constructed, on an endless handrail 5 runs synchronously with the step band.
- the handrail 5 is in each case in the Balustrade base 3 led.
- the balustrade base 3 provided with handrail inlet caps 11.
- sensors 12 are arranged. These sensors 12 monitor the Access to the escalator 1 in a certain area 13 in front of the entrance to the escalator 1, for example, the area of a starting plate 14. Die Sensors are sensitive to electromagnetic waves with a Wavelength greater than 100 pm, i. outside the optical or Infrared range.
- the sensors 12 are in the handrail inlet caps 11th Invisible integrated and each consist of a transmitter 15 and a Receiver 16, preferably a planar antenna.
- Transmitter 15 and For example, receivers 16 operate on a high frequency basis, i. at shorter wavelengths than 1 m, and respond to reflections or Rejecting high frequency waves from people and objects at.
- the sensors can be radar sensors.
- Upon entering the Monitoring range 13 of a sensor 12 are the transmitter 15 emitted waves or high frequency signals by the person or the object reflected or reflected and the associated Receiver 16 recorded. This response of the sensor 12 triggers Signal from, in an electronic part not further described here is processed and leads to start the drive of the escalator 1. If the sensors 12 fail, the escalator 1 remains in the Continuous operation.
- the senor 12 only on one side in a handrail cap 11 are attached.
- Transmitter 15 and Receiver 16 must be aligned and dimensioned in this case be that the monitoring area 13 as in the above Example is ensured.
- FIG. 3 shows a detailed view of a bevelled Handrail inlet cap 11 with a built-in sensor 12.
- the as Connection of the base serving handrail inlet cap 11 is both to Base towards and inclined to the step band. This results a the user of the escalator facing surface 11 '.
- the sensor 12 is mounted inside the handrail cap 11.
- Transmitter 15 and Receiver 16 are integrated into the handrail inlet cap 11 so that they completely hide the user and remain invisible. this has the advantage that damage to the sensor 12 by vandalism or by design, can be virtually ruled out.
- mounting the sensor 12 on the back of the Handrail inlet cap 11 simplifies manufacturing. A fitting in Mounting holes of the base is not required.
- FIG. 4 shows a second embodiment of an inventive Anteroom monitoring for an escalator 1 or a moving walkway.
- the sensors 12 with transmitter 15 and receiver 16, right or to the left of the handrail 5 in the region of the handrail deflection 10 preferably hidden in the balustrade 4 arranged.
- the functionality is the same as in the embodiment described above.
- the monitoring device is not visible to the user, as no Holes in the plastic cap are visible. This will do the whole thing Escalator much vandal-proof, because no recesses with chewing gum can be sealed.
- the new fitting of the Monitoring device can only be used with plastic caps, wherein the permeability to the electromagnetic waves in the above specified wavelength range is given. Of metal parts would the Electromagnetic waves disturbed or distracted or stopped become. So on sheet steel or Nirosta - forehead (front) plates works this monitoring device does not, because the electromagnetic waves do not penetrate the metal.
- the monitoring device of no Weather influences are misguided, as they are behind the protective Plastic cap disappears.
- the conventional vestibule monitoring however, is triggered by direct sunlight and then the escalator started.
- the escalator control print becomes smaller, and thereby cheaper, because no electronic evaluation and no amplifier for the new Monitoring device needed.
- An evaluation is but advantageously provided, which in small monitor is integrated (3-pin cable) and which the Directional detection of the movement of an object by the principle of Doppler effect allows.
