The complex also has a surveillance system contact network analyzing unit, two locating infrared sensors, three television cameras, two VCRs, two visual display devices and other devices, video surveillance and data processing.Non-contact measurement system using the latest technical tools and provide a multidimensional condition monitoring path siting, the company shall:
the complexity and high cost of the technical means employed, and the complexity of maintenance, the need for process control measurement and data processing by experienced operators;
obtaining information only after complex processing of data and the lack of control and assessment of the ways in individual parameters at the time of measurement;
inappropriate use for daily monitoring of road condition to ensure trouble-free movement or assessment results local patch or repair the path.There are various devices and systems for automatic measurement of parameters of railway track with sensors that can detect these parameters as a result of contact of the wheels or rollers measuring trucks with rail track with instant readout and data logging.A device control gauge railway track containing the vehicle on the carrier trolleys mounted on it measuring system, comprising a frame with the attached measuring rollers and displacement sensors measuring rollers associated with the device display and registry and rear tension truck, measuring cart associated with these trucks via the cable system formed by at least one flexible base line, and the position indicator flexible base straight, educated cargo, as well as contact sensor associated with the load and interact via video with range .A device for measuring the level of the railway track in the form of a measuring trolley containing a frame supported on two pairs of wheels for mounting on rails mounted on the frame level sensor and the evaluation unit, electrically connected to the level sensor, and one pair of wheels attached to the frame and the other connected through a rotary spreader .Known contact devices of the control of the railway track are simple and reliable, provide automatic measurement of parameters with instant readout and data logging and convenient for local control gauge for the purpose of Troubleshooting, and quality control of repairs.A disadvantage of the known potenzmitteln devices is their narrow purpose, the inability to simultaneously control the way in various parametri functionality selected as the closest analogue device for determining the position of the path in the plan, transverse and longitudinal profiles .A known device for measuring parameters of the railway track is made in the form of three connected with railway traction means of the measuring carriages, containing the frame with the attached obkatyvalisj rails of a track, telescopically extend wheels, and mounted measuring devices; however, the two trolleys are oriented in one direction and one in the opposite.
