Description

MONITORING SYSTEM OF VEHICLE CIRCULATION CONDITIONS AT THE CONNECTION AND OPERATION POINT BETWEEN THE CABLE, CAR, STATION AND SUPPORT CLAMP IN A CABLE DRAWN TRANSPORT

SYSTEM

FIELD OF THE INVENTION

The present invention is directed towards automated monitoring of a set of dynamic, static and geometric type physical variables, in order to inspect the actual condition of the operational, maintenance and safety variables at an operational and connection point between the cable, car, station and support clamp in a cabin type aerial cable-drawn transport medium.

BACKGROUND ART

Cable car-drawn transport system operators are often concerned about maintaining quality and safety in their service, and thus, the operating conditions of the system must be inspected. Given operating conditions are affected by component wear and tear, maintenance routine includes monitoring of variables at the point of connection and operation between the cable, car, station and support clamp. Currently, cable car drawn transport systems are being implemented as mass transport systems in urban settings generating high use and high frequency in maintenance and servicing routines. Therefore, it is convenient to automate the manual process of measuring operational, maintenance, and safety variables in the system by means of monitoring equipment.

The art has already addressed the measurement of a parameter in reference to a safety evaluation, by means of testing the clamping force of the cable car's coupling device to the carrier cable. For example, FR2750764 describes a clamping force testing device for the clamp, formed by two infrared sensors which measure distances between the clamping lever and fixed spots in swinging positions on said clamp, thus determining the clamping force. AU2003203595A1 discloses a device used to test the clamping force of the clamp, formed by at least two different measuring sensors, located inside an elastically deformable area. US4617829A refers to a device for monitoring the clamping force, by means of a prox detector, which measures the amplitude of the elastic deformation of the clutch control ramp's flexible base.

EP0582528A1 also refers to a clamping force measuring device for the clamp, which comprises a load cell type measuring element located on the clutch control ramp; in this case, the use of the load cell is inconvenient because it has a complicated implementation. These prior devices are only applied to the measurement of the clamping force, but do not take into consideration additional measurement variables.

US7,880,633 B2 discloses a monitoring device of the cable position in order to monitor the cable guide on a set of rolls in a cable transport system.

DE3822466A1 describes a method to test the position and movement of a cable transported carrier; the invention is applied to the use in machinery in the mining field, it carries out an analysis of signals obtained through optics, preferably optoelectronics. These devices are limited because they only show the cable's alignment, and however, do not include inspection and documentation of the cable's geometric defects.

Considering the aforementioned and given the high quality standards required to comply with operational monitoring, maintenance and safety conditions, it can be concluded that in general the above devices measure one sole indicator obtained from one sole physical measurement variable (i.e., clamping force of the support clamp). Therefore, a need exists to measure physical variable parameters of diverse nature in a joint manner. In contrast to prior art and as will be described in detail hereinafter, the present invention provides the joint automated measurement of several variables such as: travel distance, position, acceleration, orientation, load and pressure. The present invention is able to carry out the measurements of this set of variables automatically which regulate optimal operating at the point of connection and operation between the cable, car, station and support clamp, in a cable car-drawn transport system.
