Description
Technical field
The utility model relates to a kind of weighing device, particularly relates to a kind of weighing device that is used for the engineering carrier vehicle.
Background technology
The goods weight of engineering carrier vehicle delivery is measured through weighing device; The principle of work of existing weighing device is: the engineering carrier vehicle is with the weighing table of certain speed through certain width; Measure each weight of automobile by weighing table, adding up then draws the automobile gross weight.This weighing process is a hard real time process, need sensor in time gather automobile each data and calculate fast its weight.
Weighing device measure the weight that carries cargo and is had following weak point in the employing: at first, need to set up the weighing table that conforms to the carrier vehicle length and width, take very large-area land resource; Secondly,, all can produce certain gradient, therefore measure out of true because the shared soil of weighing table can't guarantee complete level; The 3rd, need expend very big manual work and add up every carrier vehicle general assembly (TW) of shipping goods in a certain amount of time, and can not guarantee degree of accuracy.
The utility model content
The purpose of the utility model has been to provide a kind of vehicle-mounted weighing device that is used for carrier vehicle; Can be in real time accurately show parameters such as carload, the speed of a motor vehicle, the gradient, time, suspension pressure and failure message, and can write down the information such as total amount, overload of vehicle time of number of times, the delivery of per tour driver every day, every month, the delivery of per season automatically.
The technical scheme that the utility model adopts is:
A kind of vehicle weighing device, comprise casing, be arranged on weighing measurement master controller in the casing, be arranged on the casing surface display and function button, be separately positioned on pressure transducer on four suspenders of vehicle, measure before and after the inclinometer and the car status information input port of inclination information and the information that tilts; Wherein said pressure transducer is connected with said weighing measurement master controller through shielded cable with inclinometer.
Preferably; Said vehicle weighing device also has two serial interfaces; One of them serial interface is connected with PC, be used for being configured through the running parameter of PC to said vehicle weighing device, or data download is analyzed from said vehicle weighing device; Another serial interface is connected with the vehicle management unit.
Preferably, said casing is the aluminum casing, and said weighing measurement master controller is a dsp processor.
Preferably, said car status information input port comprises lifting switching signal input port, braking and locking signal input port, vehicle speed sensor signal input port and key switch signal input port.
The utility model compared with prior art has the following advantages:
1, volume is little: this weighing device can be placed on the engineering carrier vehicle.
2, degree of accuracy is high: vehicle-mounted weighing device calculates vehicle load according to the input information of four suspension pressure transducers and inclinometer, on the road surface of injustice, also accurate weight information can be provided.
3, statistics delivery general assembly (TW): the information such as total amount, overload of vehicle time that can write down number of times, the delivery of per tour driver every day, every month, the delivery of per season automatically.
4, the scope of weighing is wide: be applicable to a series of nitrogen mounted model dumpers such as 108t, 154t, 172t and 220t.
Description of drawings
Fig. 1 is the theory diagram of the utility model vehicle weighing device.
Embodiment
Fig. 1 illustrates the theory diagram of the utility model vehicle weighing device.As shown in the figure; Wherein pressure transducer 3 has four; Be installed in respectively in four suspensions in vehicle front and back, pressure transducer 3 is the simulating signal of 4～20mA with the conversion of signals of load variations, and each pressure transducer 3 all has the shielding line of a special use to be connected on the weighing measurement PLM master controller 1; This shielding line has special back-up coat and protective seam, and enough physical strength and anti-electronic noise interference capability can be provided.In addition, the signal of inclinometer 4 registration of vehicle on the gradient, its output also connects on the PLM master controller 1.Analyze, calculate through PLM master controller 1, draw vehicle load.
Vehicle status informations such as the output signal of 4 pressure transducers 3 of PLM controller 1 reception, the output signal of inclinometer 4 and lifting switching signal 9, braking and locking signal 10, key switch signal 12; The operating condition of discriminatory analysis vehicle, state, impose a condition; The inner sampling filter of process, analysis, mode emulation gamma correction scheduling algorithm calculate the load of vehicle, gather vehicle speed sensor signal 11 simultaneously and calculate the transportation kilometer of load and add up to convert out the ton kilometre of delivery.PLM master controller 1 employing antijamming capability is strong, integrated level is high, the dsp processor of fast operation, installs with the aluminum casing, improves anti-electromagnetic interference capability.This apparatus surface is provided with LCD 2 and partial function button, can see the working condition and the relevant data of vehicle through LCD 2; The circuit main board of vehicle weighing device adopts the design of four laminates, and the most of military products that adopt of electronic component guarantee normal use the under the operating environment of extremely low temperature and mining industry harshness.
Vehicle-mounted weighing device also has serial ports 7 and serial ports 8, and wherein serial ports 7 is connected with PC 5, be used for being configured through the running parameter of PC to said weighing device, or data download is analyzed from said weighing device; Said serial ports 8 is connected with vehicle management unit 6.
Vehicle-mounted weighing device depends on pressure transducer 3 and the particular combination of PLM master controller 1 and the characteristics of each level estimate at the measuring accuracy of certain particular level.In addition, it self non-linear characteristics have all been brought on each pressure transducer 3 and the PLM master controller 1.Each dumper all has the combination of pressure transducer 3 and PLM master controller 1 uniqueness.When changing pressure transducer 3 or vehicle hanging; The setting that will carry out again PLM master controller 1; Could guarantee the precision of measurement like this; Therefore trickle level estimate must be weighed to the dumper when empty wagons and load in each transportation cycle, if simply two or three curb weight average as an empty wagons deadweight and be applied to whole level estimate, just have significant error.
