Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention will be further described.
One truck combination vehicle-mounted weighing system of the present invention, including the tractor weighing device weighed for tractor, uses
In the trailer weighing device that trailer is weighed, and trailer processor 12 and tractor processor 12 ＇；As it is shown in figure 1, tractor claims
The multiple tractor sensors including being arranged on tractor saddle 3, tractor sensor and tractor processor 12 ＇ are put in refitting
It is connected；As in figure 2 it is shown, trailer weighing device includes the multiple trailer sensor being installed on Trailer car shaft 13；Trailer sensor
It is connected with trailer processor 12 respectively.
In this preferred embodiment, as it is shown in figure 1, tractor weighing device includes tractor first sensor 1 and tractor
Two sensors 2；Owing to tractor chassis 4 is symmetrical arranged, therefore tractor saddle 3 and tractor chassis 4 contact surface also in
It is symmetrical arranged；Tractor first sensor 1 and tractor the second sensor 2 are respectively symmetrically to be arranged on and draw car saddle 3 and tractor
On the contact surface of vehicle frame 4, and it is connected with tractor processor 12 ＇ respectively.
As in figure 2 it is shown, trailer weighing device includes trailer first sensor 6, trailer the second sensor 7, trailer the 3rd biography
Sensor 8, trailer the 4th sensor 9, trailer the 5th sensor 10 and trailer the 6th sensor 11；Six trailer sensor are pacified respectively
It is loaded on the two ends of corresponding Trailer car shaft；Six trailer sensor are connected with trailer processor 12 respectively.
Wherein, tractor sensor and trailer sensor use resistance strain type sensor, resistance-strain type digital sensing
Appointing in device, capacitance type sensor, electro-optical pickoff, displacement sensor, electromagnetic type sensor and voltage-type sensor
Anticipate one or more.Cable is passed through between tractor sensor and trailer sensor and tractor processor and trailer processor
Or the mode being wirelessly transferred connects.
It is to be added by two parts and obtain that truck combination loads the weight of goods, and a part is installation trailer on Trailer car shaft 13
The gravimetric value obtained measured in real time by sensor, and the tractor sensor that a part is mounted at tractor saddle 3 records in real time
Trailer be delivered to the gravimetric value of tractor.
When vehicle loads goods, a weight part for goods is born by chassis of trailer, and a part is passed by tractor saddle 3
It is delivered to tractor；It is arranged on the trailer sensor at Trailer car shaft 13 and gathers weight information, by trailer processor 12 to weight
Information processes, it is possible to obtain the weight amount that chassis of trailer bears in real time, and another part is by the traction being arranged on saddle 3
Car sensor directly records the weight amount that tractor bears, and the addition of two parts gravimetric value i.e. be can get truck combination and carry in real time
Loadage amount, and can be shown in real time by display terminal.
The vehicle-mounted Weighing method of one truck combination of the present invention, including following operating procedure:
Step one, is gathered the axle weight signal of Trailer car shaft, and is transferred in trailer processor 12 by trailer weighing device；
Step 2, is gathered the weight signal of tractor saddle 3, and is transferred to tractor process by tractor weighing device
In device 12 ＇；
Step 3, carries out independent demarcation to the sensor in trailer weighing device and tractor weighing device respectively；Trailer
The axle weight signal-data processing of sensor uses linear fit or the method for high order matching, obtains trailer calibration coefficient and completes mark
Fixed；The weight signal data of tractor sensor process employing and directly read weight data i.e. tractor calibration coefficient is 1 to complete
Demarcate；Respectively trailer calibration coefficient and tractor calibration coefficient are stored in corresponding trailer processor 12 and tractor processor
In 12 ＇；
Step 4, after trailer loads goods, trailer sensor gathers axle weight signal, according to trailer calibration coefficient by trailer
Processor carries out data process, restores trailer and loads the weight of goods；The weight that trailer loads goods senses with tractor
The weight data of device output is added and obtains truck combination loading gross weight, and is shown by display terminal.
Truck combination vehicle-mounted weighing system of the present invention demarcates the mode using tractor and trailer individually to demarcate, traction
Car uses sensor, can be fixed at the advance rower that dispatches from the factory, it is possible to directly read the numerical value of load capacity, be arranged on tractor saddle 3
After place, can be used directly, it is not necessary to again demarcate.
Trailer portion sensor is indirectly measured by measurement axletree deformation quantity and is obtained Trailer type frame for use in vehicle load capacity, need to install
Demarcate after completing, by wheel metering equipment, vehicle-mounted weighing system trailer portion of the present invention is demarcated, at trailer
Load Different Weight counterweight or other substitutes, exported with corresponding axle metering equipment by contrast sensor, data are carried out
Linear or high order (secondary, three inferior) matching, obtains calibration coefficient, and writes in trailer processor, complete the mark of trailer portion
Fixed.
After completing to demarcate, loading the goods of constant weight at trailer, now, it is m1 that tractor part records weight；Trailer
It is m2 that part records weight.
So, now vehicle contained goods weight m just can be expressed as: m=m1+m2.
If the number twice less than the number of axle installed by truck combination trailer portion sensor, i.e. select any one or more car
Axle installs one or more trailer sensor, now, at trailer portion timing signal, only need to by axle metering equipment and sensor it
Between corresponding relation be modified slightly.
Tractor sensor at tractor saddle 3 is capable of carrying a load of m3；Trailer sensor at Trailer car shaft records weight
Value is m4.
Then, the gravimetric value that truck combination loads is: m=m3+m4
At some in particular cases, tractor sensor mounting location can be changed, tractor saddle 3 be replaced by and lead
Drawing at car axletree, mounting means is consistent with trailer sensor, timing signal, and tractor is independently demarcated with trailer, demarcates mode
Mode is demarcated consistent with trailer sensor in above-mentioned steps three.After completing to demarcate, Trailer car shaft sensor institute's measured weight and traction
Car axletree institute measured weight sum is truck combination loading gross weight.
Tractor weighing device trailer weighing device both can use separately as weighing system, it is also possible to is arbitrarily incorporated in one
Rise and use, it is achieved the real-time detection of truck combination vehicle load.
