Description
A SENSOR AND SAFETY SYSTEM OPERATED WITH THIS SENSOR
Technical Field
The present invention relates to sensors employed so as to sense and control location and speed information.
In particular, the invention relates to a sensor reading the absolute location and speed of an object moving on a linear line and a safety system operated with said sensor. The invention is a sensor reading the absolute location and speed of object like an elevator moving on a linear line and a safety system equipped with said sensor. A safety device that carries out the system is provided. State of the Art
There are applications reading the location and speed of the object moving on a linear line. In the present application, the safety function is as below: Location, speed and acceleration is measured. Magnetic and optical types of reading methods are found and applied. Technical structures in the known application comprise only measuring features.
These structures evaluate location, speed and acceleration information and yet do not carry out various safety functions. These known optical applications does not offer a solution pertaining to dust and pollution problems.
In the US patent application numbered US20090252326, there is a series of optical sensors engaging with holes on a line on the PCB in the sensing box placed in conformity with PRBS coding system.
However, when only the coding system is employed, the precision that may be obtained is limited to how close sensors reading the line can be placed physically on PCB. Since optical sensor comprise a certain size, they cannot be placed on PCB very closely. This limits the resolution that may be obtained by means of the technique described in the US patent application US20090252326.
Various patents disclose measuring methods. Since classical known solutions do not comprise safety apparatus feature, they cannot carry out the electronic parachute brake control.
The problem faced in all of the digital-coded absolute reading methods and in phototransistors is that the reading is unstable in transition regions, as a portion of phototransistors remains in the dark and its another portion remains in the light in transition regions between collateral two locations.
The problem is solved by means of below stated methods in the present techniques. In the US patent application US8489970, analog reading is carried out instead of digital one. The method is a method that both is very complex and may be affected by thermal and electrical noise effects, because analog reading circuits will be employed.
In the US patent application US4780894, this problem is tried to be solved by means of arranging the code system such that only one bit would be always changed between collateral two locations. Since this method may carry out the location separation with the distance of max. 2AN*d, even though the available rotary location is applied in decoders, in the applications requiring the precision about 1 mm and hundred meters of measuring distance such as a lift, the method is not applicable, since the required numbered of sensor and line is too much. the US patent application US2017066625 discloses a structure deciding if the measuring value obtained from sensors are correct, by means of evaluating the condition of control (CLK) sensor on a different line. This method cannot carry out the
reading process before the object of which location is to be measured moves, as the reading cannot be performed in transition regions.
It is required a novel technical solution overcoming all of the disadvantages of the above-mentioned methods.

Detailed Description of Invention
The measuring holes (3,4) on the first line (301 ) are placed in accordance with PRBS coding system disclosed in the patent document US20090252326A1. The series of optical sensor corresponding to the measuring holes (3,4) on the first line (301 ) are on the PCB receiver circuit board (6) in the sensor device (1 ).
Flowever, when only the coding system is employed, the precision that may be obtained is limited to how close sensors reading the line can be placed physically on PCB receiver circuit board (6). Since optical sensor comprise a certain size, they cannot be placed on PCB receiver circuit board (6) very closely. And this limits the resolution that may be obtained in the present technique (US20090252326A1 ).
The minimum error rate that may be achieved by means of using only this method equals to the minimum distance between location measuring holes (4).
Even if it is possible with similar CCD sensors used in scanners (US5436476) instead of decreasing the distance between optical sensors, these sensors are costly due to their complexity pertaining to manufacturing methods.
The inventive method uses cheaper and simpler phototransistors instead of said quite expensive sensors and reduces the precision limitation by means of the second line (302).
Said second line (302) works just like a Vernier caliper (US4375722A, US6332278). Advantage of the Vernier method is to allow for measuring, as much as desired, at the higher precision than the distance between two sensors by means of increasing the number of sensors and measuring points, i.e. measuring holes (3,4) without reducing the distance between measuring holes (3) and sensors in the location measuring holes (4).
The precision that may be obtained through the Vernier method is calculated as below:
H = (D-d)
H: Precision
D: distance between each measuring point (hole)
d: distance between each sensor (phototransistor)
Disadvantage of the Vernier method is that the distance in which measurement may be carried out is limited to the number of sensors.
The distance that can be measured by only Vernier Method is calculated by means of the following formula:
X = (D-d) * N
X: The distance that can be measured
N: Number of the sensor (phototransistor)
D: distance between each measuring point (hole)
d: distance between each sensor (phototransistor)
The method developed may overcome the drawback of the methods by means of combining said two methods.
