Description

The invention relates to devices for measuring distances to an object by means of an optical range finder.

The closest in technical essence and the achieved result is the SYSTEM OF MEASURING DISTANCE TO THE SUPPORTS OF THE RAILWAY CONTACT NETWORK FROM A MOBILE OBJECT (patent RU 85999, publ. 20.08.2009, bull. No. 23). This well-known system is adopted as a prototype.

A disadvantage of the known SYSTEM OF MEASURING DISTANCE TO THE SUPPORTS OF THE RAILWAY CONTACT NETWORK FROM A MOBILE OBJECT is the low reliability of the measurement results in the waiting area of the measurement object, since within the waiting zone there may be objects similar to supports of the contact network.

The technical results aimed at creating this utility model are to eliminate the disadvantage of the prototype, expand the functionality of the device by introducing the function of measuring the distance from the car roof to the main retainer of the contact network support and increasing the reliability of the measurement results due to the possibility of choosing from the data array obtained the distance sensor to the contact network poles in the waiting area only of data that coincide in time and path with distance data main retainer.

The technical result is achieved by the fact that the proposed device for measuring the distance to the supports and the main clamp of the contact network of the railway with a moving object (for example, a laboratory car), containing two devices for determining the position of the contact wire in plan, placed on the respective current collectors on the roof of the car laboratories, an optical range finder, a recording device, a path-speed sensor, a pulse shaper and an electronic key, - additionally contains an optical range finder opt the other axis of which is located on the same plane of the orthogonal axis of the path with the range finder of measuring distances to the supports of the contact network and the angle between these axes is 90 °, while the output of the device for determining the position of the contact wire in plan is connected to one input of the pulse shaper, the second input of which is connected to the output of the speed path sensor, and the output of the pulse shaper is connected to the control input of the electronic key, the second input of which is connected to the output of the optical range finder, and the output of the electronic key connected to one of the inputs of the recording device, the second input of which is connected to the output of the newly introduced optical range finder.

The proposed utility model is illustrated in the drawing, where in FIG. 1 shows a layout of the main nodes of the proposed device on a moving object (laboratory car), FIG. 2 is a block diagram of a device for measuring the distance to the supports and the main latch of the contact network of the railway with a moving object.

The device for measuring the distance to the supports and the main clamp of the contact network of the railway from a moving object (laboratory car) contains two devices for determining the position of the contact wire in plan 1 (Fig. 1, 2), placed on the corresponding current collectors of the laboratory car 2 (Fig. 1) by testing the contact network, on the roof of the laboratory car near the geometrical optical range finder 3 (Fig. 1, 2) is placed, at a distance of 61 and 62 from the respective current collectors and an additional optical range finder 8 (Fig. 1, 2). The device also contains (Fig. 2): a path-speed sensor 4, a pulse shaper 5, an electronic key 6, a recording device 7.

Moreover, the output of the device 1 for determining the position of the contact wire in plan is connected to one input of the pulse shaper 5, the second input of which is connected to the output of the path-speed sensor 4, and the output of the pulse shaper 5 is connected to the control input of the electronic key 6, the second input of which is connected with the output of the optical range finder 3, and the output of the electronic key 6 is connected to the input of the recording device 7, the second input of which is connected to the output of the newly introduced optical range finder 8.

A device for determining the position of the contact wire in the plan is made according to the patent of the Russian Federation for utility model No. 73284, published on 05/20/2008, bull. fourteen.

The proposed device operates as follows.

During the movement of the laboratory car 2, the optical range finder 3 operates in a continuous mode. In the area of the inflection point of the contact wire, the so-called "zigzag", from the output of one of the alternately working devices 1 for determining the position of the contact wire in the plan, the signal is fed to one input of the pulse shaper 5, the other input of which receives a signal from the path-speed sensor 4. From the output of the pulse shaper 5, a signal is sent to the control the input of the electronic key 6, to the other input of which the signal from the optical range finder 3 is received. The electronic key 6 commutes the signal from the optical range finder 3 to the input of the recording device 7. The impedance sensor 4 an pulse whose width is proportional to the distance 51 or 62 between the optical range finder 3 and one of the devices 1 for determining the position of the contact wire in plan at the moment, while the signal from the range finder measuring the distance to the main clamp of the support of the contact network 8 is directly transmitted to the recording device.

Thus, from the array of signals from the distance sensor to the pylons of the contact network, only one is registered that in time and distance coincides with the signal from the distance sensor to the main latch.

The presence of distinctive features in the claimed utility model allows us to conclude that it meets the condition of patentability “novelty”.

The criterion of "industrial applicability" of the claimed device is confirmed by its potential effectiveness in comparison with the prototype

The proposed device for measuring the distance to the supports and the main clamp of the railway contact network from a moving object can be effectively used in laboratory cars for testing the contact network of electrified sections of the railways of Russia and the CIS countries.
