Apparatus for recording the condition of equipment, such as street lighting, located at spaced positions along a route, comprises a control unit (6) in the form of a personal computer, to which various inputs may be provided. The apparatus also comprises logging means for logging the position of the vehicle in the course of the vehicle's travel along the route, such as a distance transducer (8) adapted to be connected to the vehicle engine. The apparatus also comprises sensing means providing output signals indicating the condition of the equipment being monitored, such as the output of street lamps as the vehicle drives therebeneath, the sensing means being in the form of a sensing device (10) comprising an array of photo-sensors, the sensing device (10) being adapted to be mounted on the roof of the vehicle. In use, the vehicle will commence travelling along the route, and output signals will be fed to the control unit (6) both from the distance transducer (8) and the sensing device (10), in a manner in which the output from the sensing device is correlated with the output from the distance transducer. The control unit (6) may be connected to a portable terminal and a printer (16), to produce a print-out indicating the condition of the street lighting along the route. |
