Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1～shown in Figure 3, automobile mounted self-measuring device of the present utility model, comprise automobile hopper 1 and be arranged on lifting structures 3 on the automobile hopper 1, automobile hopper 1 is provided with position detecting device 2, lifting structures 3 is provided with pressure transducer 4, position detecting device 2 is electrically connected data processing module 5 with pressure transducer 4, and data processing module 5 is electrically connected display unit 6.When automobile material is carried to topple over the place after, the 1 beginning discharging of automobile hopper, in discharge process, lifting structures 3 lifts discharging with automobile hopper 1, position detecting device 2 detects the lifting distance of automobile hopper 1 in this process, pressure transducer 4 is used for detecting the lifting force of lifting structures 3 in the lifting process, then, detected lifting distance is transported to data processing module 5 with lifting force to be handled, calculate the charging capacity of car load, and, the data that deal are managed through the data of display unit 6 display process.In this embodiment, position detecting device 2 can be arranged on the optional position of automobile hopper 1, as long as can measure its lifting distance, similarly, lifting structures 3 also can be arranged on the optional position of automobile hopper 1, as is arranged on automobile hopper 1 top, side.As preferred embodiment, position detecting device 2 and lifting structures 3 are arranged on the bottom of automobile hopper 1.Like this, can make structure more reasonable, can not cause the integrally-built influence of automobile.Position detecting device 2 can adopt the displacement transducer that is arranged on automobile hopper 1 bottom, and as optimal way, position detecting device 2 adopts the rubber-like travel switch, is separately positioned on automobile hopper 1 front end and rear end.K1 as shown in Figure 2 and K2, when automobile began to unload, automobile hopper 1 was positioned at K ₂The position, along with the unloading beginning, automobile hopper 1 rotates around pin joint under the effect of lifting structures 3, the rear end contact resilient detector switch K of automobile hopper 1 ₁The position, thus the lifting distance of automobile hopper 1 obtained, with respect to displacement transducer, it is simple in structure, and is with low cost, and its elasticity then can have an elasticity to automobile hopper 1 and step down when 1 upset of automobile hopper, can not influence the turning operation of automobile hopper 1.

In the above-described embodiment, described lifting structures 3 can adopt gear transmission structure, pneumatic cylinder structure, realizations such as four bar structures, and as optimal way, lifting structures 3 adopts elevating ram, and pressure transducer 4 is arranged on the oil supply loop.Adopt the mode of oil cylinder, its reliable in structure, simple.

In the above embodiment, behind lifting distance that detects automobile hopper 1 and lifting force, its computation process is as follows: its measuring principle sketch as shown in Figure 2, elastomeric check K switch 1, K2 are installed on the afterbody and the head of automobile hopper 1 respectively, to finish the detection to automobile hopper 1 lift location; Pressure transducer 4 is installed on the oil supply loop of automobile hopper 1 elevating ram, to finish the detection to hopper lifting force F.Data processing module 5 and processing and the computing of display unit 6 (micro computer) in order to finish data, its computing are based on such principle: the weight G of loaded material and material are under the effect of lifting force F, and when moving to the B point by the A point, power F is along motion path d _lIntegration and object the speed V and the discrepancy in elevation h that when the B point, are had linear:

$G=\frac{1}{0.051v^2+h}\underset{A}{\overset{B}{\∫}}F\·\mathrm{dl}$

Wherein, discrepancy in elevation h is a definite value by the installation site decision of elastomeric check switch; And can moving to the time that B orders by timing A point, speed V tries to achieve:

$v=\frac{l_{\mathrm{AB}}}{t_{\mathrm{AB}}}$

And according to the numerical computation method (its geometric meaning is as shown in Figure 3) of integration:

$\underset{A}{\overset{B}{\∫}}F\·\mathrm{dl}=\underset{n\→\∞}{\lim }\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{F}_i\·\mathrm{\Δ}{l}_i=l_{\mathrm{AB}}\·F_{\mathrm{av}}=l_{\mathrm{AB}}\·\frac{1}{n}\·\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{F}_i$

Promptly this integrated value equal object of which movement apart from l _ABMean value F with power F _AVLong-pending.And by the microcomputer timing F that samples repeatedly _iValue, we just can be in the hope of F _AV, and finally try to achieve the weight G of lorry loading thing:

$G=\frac{l_{\mathrm{AB}}}{0.051v^2+h}\·\frac{1}{n}\·\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{F}_i$

Then, lift location and the Weight Loaded of data processing module by automobile hopper 1 judges whether automobile finishes once effectively delivery, and this loads whether underload or overload.When delivery is effective, with the data storage filing, use automatically for the stock ground operation management.
