Description of the drawings
Fig. 1 is the utility model vehicle weighing device functional block diagram.
Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment.
Embodiment 1
Fig. 1 shows the functional block diagram of the utility model vehicle weighing device.As shown, wherein pressure sensor 3 is shared
It four, is separately mounted to before and after vehicle in four suspensions, the signal of load variation is converted to the mould of 4 ~ 20mA by pressure sensor 3
Quasi- signal, each pressure sensor 3 have a dedicated shielding line to be connected on weighing measurement PLM master controllers 1, the shielding line
There are special reinforcing layer and protective layer, enough mechanical strengths can be provided and does the ability of electronic noise interference.In addition, tilting
4 record vehicle of meter is converted to the analog signal of 0 ~ 5V in the gradient and inclined signal, and output also connects on PLM master controllers 1.It is logical
It crosses the analysis of PLM master controllers 1, calculate, obtain vehicle load.Vehicle weighing device carry state display lamp, show respectively empty wagons,
Three kinds of states of 70% load and overload, three kinds of states are shown by the display lamp of three kinds of different colours, pre- in time to overload
It is alert.
PLM controllers 1 receive output signal, the output signal and lifting switch of inclinometer 4 of 4 pressure sensors 3
The vehicles car status informations such as signal 9, braking and locking signal 10, key switch signal 12, subbranch's operating mode of discriminatory analysis vehicle,
State, setting condition are filtered with crossing internal sample, are analyzed, Modal Analysis gamma correction scheduling algorithm calculates the effective of vehicle
Load-carrying, while acquiring speed sensor signal 11 and calculating the transport kilometer of load and the accumulative ton kilometre for being converted into delivery.PLM master
Controller is installed with aluminum casing using strong antijamming capability, the dsp processor that integrated level is high, arithmetic speed is fast, is improved anti-electricity
Magnetic disturbance ability.The mainboard of vehicle weighing device is largely used military products, is ensured in pole using four layers of design, electronic component
Normal use under low temperature and the operating environment of mining industry harshness.
Also there is vehicle-mounted Weighing management device serial ports 7, serial ports 8 and CAN mouths 13, wherein serial ports 7 to be shown with communication interface
Show that terminal and keyboard 2 connect, it can be seen that the working condition of vehicle data related with download to PC 52, the serial ports 8
It is connect with vehicle scheduling unit 6；The CAN13 is connect with vehicle management control system 14, and user can be connect by carrying communication
Mouth display terminal and keyboard 2 download the data to PC 5, easy to use, greatly meet the demand of user.
Vehicle-mounted Weighing management device depends on pressure sensor 3 and PLM main controls in the measuring accuracy of some specific grade
The characteristics of specific combination of device 1 and each level estimate.In addition, being brought on each pressure sensor 3 and PLM master controllers 1
The non-linear behavior of own.Each dumper all has the 1 unique combination of pressure sensor 3 and PLM master controllers, more
When changing pressure sensor 3 or vehicle hanging, setting again is carried out to PLM master controllers 1, just can guarantee the essence of measurement in this way
Degree, therefore a subtle level estimate has to weigh to each transportation cycle hollow car and dumper when load,
As soon as if the average of two or three curb weight as the dead weight of empty wagons is simply applied to entire level estimate, have
Significant error.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, one skilled in the relevant art within the scope of knowledge, can also be under the premise of not departing from this patent objective
