Managing system for construction vehicles
First Claim
1. A managing system for a construction vehicle having front and rear wheels for which hydro-pneumatic suspension cylinders are provided, comprising:
- a set of sensors including sensors operably attached to a brake fluid meter, an engine oil meter, a hydraulic fluid meter, a transmission oil meter, a retarder fluid meter, a radiator water level gauge and a battery liquid meter, respectively;
a vehicle travelling speed sensor unit for detecting a travelling speed, a highest and lowest vehicle travelling speeds and a distance travelled;
a vehicle control monitor, including;
means for computing the weight of load according to respective pressures applied to the hydro-pneumatic suspension cylinders;
means for recording an unloading time, the weight of load and the kind of load according to a combination of a vessel raising/lowering signal and a signal of a kind of load inputted by means of ten-key;
means for computing fuel consumption per unit time according to a flow rate of fuel in a fuel supply line f an engine;
means for computing the vehicle travelling speed, the highest and the lowest vehicle travelling speeds and the distance travelled according to an output signal from said vehicle travelling speed sensor unit;
means for recording the results of a pre-operation check of the vehicle according to output signals from said sensors attached to the brake fluid meter, the engine oil meter, the hydraulic operating fluid meter, the transmission oil meter, the retarder fluid meter, the radiator water level gauge and the battery liquid meter, respectively;
means for recording working hours measured by a built-in timer; and
means for recording vehicle maintenance and descriptive data;
a non-contact type recording card for recording the information recorded in said vehicle control monitor;
means for reading out the information recorded in said recording card; and
means for compiling a management ledger on the basis of the information read out from said recording card.

Abstract
A managing system for a construction vehicle which has for its object to enable management of the vehicle relating to pre-operation checking, maintenance and summary of work load, etc to be conducted easily and quickly. This managing system comprises a vehicle control monitor (7) for inputting and recording information necessary for management of the vehicle from a plurality of information sources, a non-contact type recording card (27) for recording the information recorded in the vehicle control monitor (7), a card reader/writer (40) for reading out the information recorded in the recording card (27), and a printer (42) and a personal computer (43) for compiling management ledgers and displaying data on the basis of the information read out by the card reader/writer.
