摘要:
A system is disclosed for identifying the location of a vehicle (11), assembling data related to vehicle performance and correlating the assembled data with vehicle location. From the correlation of data and location, a data base is generated that provides information for monitoring performance of the vehicle (11), reporting irregularities in the performance and generating control signals for commanding vehicle movement. The system comprises a plurality of signposts (180) located at intended destinations of a vehicle (11), wherein each signpost (180) is characterized by indicia that are distinctive to the associated destination. On board each vehicle (11) is a device (198) for detecting a signpost when the vehicle is within a predetermined proximity of it. The device generates data indicative of the location of the vehicle in response to detection of a signpost (180). Also on board each vehicle are sensors (49,102,105,107,109,110,116) for collecting and recording data indicative of vehicle performance. The location and performance data are correlated to provide a data base for use by a computer in monitoring the vehicle performance, reporting irregularities in the performance and locating the vehicle and controlling the movement of the vehicle.
摘要:
The invention relates to an apparatus for accurately measuring the weight of a load carried by a truck body 13 which is mounted on a truck frame 15. The apparatus is located along an interface between the truck frame 15 with the load carried by the truck body 13 and uniformly distributes the weight of the body onto the frame along the interface. In order to measure the weight of the load, the apparatus includes pressure sensors 51 a-d which communicate the entire weight of the load to the truck frame 15. The pressure sensors 51a-d provide an electrical signal proportional to the pressure exerted by the load on the apparatus. This electrical signal is processed to calculate the weight of the load carried in the truck body. By providing a pressure sensing apparatus at an interface between the load and truck frame, the weight on the load carried by the truck body can be continually monitored without interrupting the loading, hauling and dumping routine. A sensor processing unit 101 responds to the continually monitored weight data and the like to provide hauling parameters to track the performance of the truck and to provide a data base to a central computer from which data can be gathered for efficiently controlling the movement of a plurality of trucks.
