Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
A kind of haul truck automatic weighing device 100 that the utility model relates to, comprise oil pressure sensor 1, this oil pressure sensor 1 is arranged on the elevating ram 4 pressure duct junctions of vehicle lifting mechanism, so can directly measure the hydraulic fluid pressure of elevating ram 4, and installation and maintenance are quite convenient.Further, as shown in Figure 1, for the data that allow oil pressure sensor 1 obtain can transmit to allow managerial personnel know as early as possible, in real time, this automatic weighing device 100 also comprises GPS car-mounted terminal 2 and center monitoring platform 3, oil cylinder oil pressure when this GPS car-mounted terminal 2 is connected to obtain lifting process with oil pressure sensor 1, this GPS car-mounted terminal 2 also is connected by communication with center monitoring platform 3.
The GPS car-mounted terminal 2 that automatic weighing device 100 adopts is the GPS equipment of a collection location, control, data acquisition, A/D input, intake input.Equipment has 10,2 tunnel precision, the analog quantity of 0～5V input and reserved analog quantity linear function (Y=aX+b) calibration equation, the direct output voltage of input pressure transmitter, and be converted into the vehicle weight data by calibrating parameters, and then transfer to the center monitoring platform 3 of main station system by GPRS network, simultaneously terminal also can external vehicle speed mileage, the sensors such as oil mass and rotating speed, some operating condition parameters of vehicle are gathered and computing.
Monitor supervision platform shows the load-carrying data of vehicle, and the load-carrying data that gather are calculated and added up, and gathering generating report forms can be for downloading and printing.Monitor supervision platform also can be to GPS car-mounted terminal 2 sending controling instructions, and upgrading and the parameter of TCP arranged etc.When overload threshold value that vehicle load surpass to be set, platform produces warning message, forms corresponding alarm logging, and the user of long-time overload is reminded, and warning maybe can be carried out vehicle oil-break and outage.
As shown in Figure 1, in the present embodiment, primary processor 21, GPS module 22, GPRS module 23 and the power-supply system 24 for providing power supply to supply with are provided this GPS car-mounted terminal 2, this primary processor 21 is connected with oil pressure sensor 1, and this primary processor 21 is connected with GPRS module 23 by GPS module 22.This primary processor 21 specifically adopts NXP-LPC2378/88.
As shown in Figure 2, wherein:
Dead weight capacity: G;
Lifting thrust: F=P*S;
At the uniform velocity lifting the initial segment 2. (see figure 3) have:
F*L1=G*L2
: G=(F*L1)/L2
=P*(S*L1/L2)
So: dead weight capacity G=P*K(lifting coefficient), K=(S*L1/L2);
In sum, the dead weight capacity of vehicle is directly proportional to the elevating ram oil pressure, detect the elevating ram oil pressure and get final product the dead weight capacity that indirect calculation goes out vehicle, pressure curve (see figure 3) by lifting process can be found out, the pressure curve of oil cylinder lifting process is divided into 3 stages: the 1. initial accelerating sections of lifting, 2. at the uniform velocity lifting the initial segment, 3. lifting subsequent segment.
Load-carrying need to be measured is the 2. oil cylinder working-pressure of section, be that the oil cylinder extension elongation is when 10～20cm, lifting device has completed lifting and has accelerated to enter at the uniform velocity lifting state, now compartment is in the relative level state, pitch angle is to K(lifting coefficient) error effect little, the oil cylinder working-pressure P value of now measuring can reflect load condition indirectly.Equipment can continuous coverage (sampling rate 16 points/per second) oil cylinder pressure, the decomposition pressure curve is also isolated 2. section curve from curve, computes weighted to obtain the P value that error is less.
Like this, a kind of haul truck automatic weighing device 100 that the utility model relates to, it is, in elevating ram pressure duct junction, oil pressure sensor 1 is set, and the pressure data that recycling oil pressure sensor 1 detects when vehicle lifting overturns is converted into vehicle load.With respect to the traditional detection mode, the utlity model has the characteristics such as simple in structure, easy for installation, that cost is low and reliable and load-carrying data acquisition is convenient under bad working environments.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not breaking away from patent category of the present utility model.
