Equipment for inspecting and/or monitoring a points installation (1) with one or more sets of points (7, 8, 9), comprising at least one optoelectric sensor (2, 3, 4, 5) located near the installation, wherein the sensor is arranged to measure a geometric parameter of the points installation (1). The sensor, which can be disposed at a defined spacing (a) from the installation, can supply a signal value indicative of the measured parameter to evaluating means (10), which can, for example, compare the value with a threshold value and issue a fault signal (S) if the threshold value is exceeded. Preferably the sensor is a laser scanner, camera or LCD camera and maybe located at a defined spacing from and height relative to the installation. The parameter may be a geometric magnitude of a switching device, frog, track width to rail height. |
