Abstract

The invention discloses a kind of implementation method that axis weight calculation and number of axle statistics are weighed in vehicle, the method for processing weighing data for being related to the vehicle used on highway to weigh.For general highway vehicle Weighing system number axis and the inaccurate problem of single shaft weight, a kind of method for proposing new axle weight calculation and number of axle statistics.Using amplifier, axis signal is divided into two, using different multiplication factors, all the way for the weighing of single shaft axle weight, judged and statistics for the number of axle all the way.Effectively solve the problems, such as multiplication factor is chosen at contradiction in two-way application, improves the accuracy rate of number of axle measurement and the precision of complete vehicle weight measurement during vehicle is weighed.

Description

The implementation method of axis weight calculation and number of axle statistics is weighed in vehicle
Technical field
The invention belongs to transport information field, the treatment side of the vehicle weighing data used on a kind of highway of proposition Method.
Background technology
The meausring apparatus of highway vehicle weighing system is mainly made up of following part:Sensor, amplifier, A/D turn Parallel operation, single-chip microcomputer etc..Weighing sensor is the core of weighing apparatus, and it converts gravitational force to electric signal, and sensor output signal is several According to source.The signal of sensor amplified could need to be used.The signal of sensor output is amplified, becomes the electricity of 0~5V Pressure signal output.Amplified signal is sent in A/D converter, converts analog signals into data signal.A/D converter is again Data are transported in computer and are processed.Actually weigh during, we typically by car it is general be divided into cart and dolly two Plant vehicle.The length of Wheel axle identifier is general shorter than the distance of two tires of vehicle, this ensures that theres most at any time Tire on only one of which axle is in the state being weighed.When have vehicle pass through meausring apparatus when, each axle by that can show One sinusoidal wave shape, we are exactly to judge the number of axle by way of such number waveform numbers.It is actual due to the presence of noise Erroneous judgement occurs in operating process, we introduce a level as validation value, and this level should be than the waveform peak of noise It is high.Meanwhile, this level should be smaller, no more than the minimum value of dolly single shaft weight, otherwise occurs in weighing cart and loses axle Phenomenon.So, we introduce amplifier, and axis signal is amplified, so as to avoid the appearance of this contradiction.So, from this Said in individual angle, multiplication factor should be as far as possible big.But in the weighing of single shaft weight, it is intended that by the electricity for adjusting amplifier Position device changes gain so that output signal is exported close to full scale in the case of full heavy burden, but no more than A/D converter Maximum range.So, to from the perspective of from this angle, multiplication factor again can not be excessive.In face of the problem of such a contradiction, I Propose the processing method being divided into two, axis signal is divided into two-way, all the way using as far as possible big multiplication factor, for the number of axle Statistics, all the way using relatively small multiplication factor, for single shaft weight calculation, which enhances the standard of number of axle measurement during vehicle is weighed True rate and the precision of vehicle measurement.
The content of the invention
Axis weight calculation and the implementation method of number of axle statistics are weighed in vehicle it is an object of the invention to provide a kind of, is improve whole The accuracy rate of number of axle measurement and the precision of vehicle measurement in car weighing.
The technical scheme is that:A kind of implementation method that axis weight calculation and number of axle statistics are weighed in vehicle, its feature It is to utilize amplifier, axis signal is divided into two, all the way using as far as possible big multiplication factor, for number of axle statistics, axle is believed Number peak value draw high, select level higher, real axis signal is different from noise signal as far as possible, prevent from occurring during number axis Erroneous judgement;Another road use relatively small multiplication factor, for single shaft weight calculation so that cart full load output data through putting Still, so as to cover the demand of weighing of all vehicles on highway, improve whole in the process range of A/D converter after big The accuracy rate of number of axle measurement and the precision of vehicle measurement in car weighing.
Defect or deficiency that data processing for existing weighing system is present, the present invention use a kind of place being divided into two Reason method, two-way is divided into by axis signal, all the way using as far as possible big multiplication factor, for number of axle statistics, all the way using relatively Small multiplication factor, for single shaft weight calculation, makes the probability of number of axle accuracy of judgement and the precision of vehicle weighing results all lifted.
Brief description of the drawings
Fig. 1 is theory diagram of the invention.
Fig. 2 is the amplifier circuit figure of traditional number of axle statistics.
Fig. 3 is the amplifier circuit figure of traditional single shaft weight calculation.
Fig. 4 is weighing system amplifier circuit figure of the present invention.
Specific embodiment
As shown in Figure 1.The weighing system of this highway includes weighing sensor (weighting platform), the big portion of electronic circuit two Point, as shown in Figure 1.The weight signal of vehicle is converted to weighing sensor (weighting platform) electric signal of simulation;Electronic circuitry part Including:
Signal amplifying apparatus:Due to the analog electrical signal very little of weighing sensor output, amplifying device is by weighing and sensing The analog electrical signal of device output is suitable to the voltage range of acquisition chip collection to reach by one-level or multistage amplification.Protecting In the case of demonstrate,proving the number of axle accurately, the degree of accuracy of weighing results is improved.
Signal pickup assembly:Weighing-up wave after amplification is converted into data signal by analog signal, to facilitate at computing Reason.
Signal processing apparatus:The data signal that will be collected is by a series of relevant information for being calculated the car.
Display device:Show the relevant information of vehicle.
Storage device:For storing the comparative quantity needed for calculation process, related parameter and information of vehicles.
Arthmetic statement and experimentation
(1) circuit diagram of number of axle statistics is as shown in Figure 2, it is known that R1=2k, R2=620k, R '=5M.According to INA326 chips Characteristic understands that its multiplication factor computing formula is as follows:
G=2 (R2//R’)/R1Can obtain
G=551
By above-mentioned calculating, the multiplication factor of INA amplifiers is that the multiplication factor that 551, i.e. axle are counted again is 551.
(2) circuit diagram of single shaft weight calculation is as shown in Figure 3, it is known that R1=2k, R2=390k, R '=5M.According to INA326 chips Characteristic understands that its multiplication factor computing formula is as follows:
G=2 (R2//R’)/R1Can obtain
G=360
By above-mentioned calculating, the multiplication factor of INA amplifiers is 360, i.e. the multiplication factor of single shaft weight calculation is 360.
In sum, larger amplifier gain is applied in number of axle statistics, it is to avoid the situation for judging and losing axle by accident occurs. Less amplifier gain is applied in single shaft weight calculation, the precision of single shaft weight calculation is improved.The weight calculation mode greatly improves to weigh and is The performance of system and expand the use category of the system.
Using the experimental comparison figure before and after this method
Before using this method, traditional weighing system amplifier circuit uses single gain amplifier, it is impossible to while meeting The high-gain of number of axle statistics and the low gain demand of single shaft weight calculation.
As shown in figure 4, can simultaneously meet the high-gain and single shaft meter of number of axle statistics using the amplifier circuit after this method The low gain demand of weight.
