Related CAN nodes.LOAD CELLS is four.The sensor group is strain gauge transducer, and this programme have selected adhesive type should
Become sensor, strain transducer can calculate spring carried mass by measuring vehicle leaf spring surface strain values, and then obtain
Vehicle full payload and each axle axle load.The advantage of adhesive type strain transducer mainly has following several：Side amount answers precision and sensitive
It is higher, dependable performance and stable；Foil gauge is very easy to use, light weight, ring that speed is fast, and size is little, structure is relatively simple
It is single, kinetic measurement had both been can be applicable to, static measurement is can be applicable to again；Detection range is wide, you can survey plastic deformation, also can detect bullet
Property deformation, deflection is between 1%-20%；To external world environmental suitability is very strong, can in high/low temperature, under water pressure, radioprotective and
The very severe condition of the environment such as high-intensity magnetic field is used.Strain transducer is made up of foil gauge and measuring circuit two parts.This programme
Metal foil stain gauge is selected, because metal forming grid can work together well than relatively thin with elastomer, therefore certainty of measurement
It is very high.Surface area is big, and beneficial to radiating, maximum operating currenbt is larger, can export higher voltage signal, and range of application is larger.
Suppleness is good, can be secured at variously-shaped band and survey.In actual applications, mechanical strain is often all smaller, has very
Extremely cannot direct measurement.If very small resistance change is detected, while again resistance relative variation
△ R/R are converted into the change of curtage, it is desirable to road blocking or the change of voltage produced by special measurement test specimen strain variation
Change, it is desirable to the measuring circuit of special measurement test specimen strain variation, generally using AC bridge or direct-current bridge.Bridge circuit
With very high sensitivity, and measurement range is wider etc., therefore extensively applies bridge circuit in actually measurement.It is main at present
There is the power supply mode of two kinds of bridge circuits of constant pressure and constant current, it is contemplated that vehicle source is constant voltage source, so using constant pressure full-bridge electricity
Road, not only bridge sensitivity is high for full-bridge circuit, and when load tends to infinite, will not produce nonlinearity erron, while also having
There is the function of temperature-compensating.The variable quantity that above-mentioned angular transducer is accelerated by measurement gravity, and then change angled change.
The measurement mutual vertical axises of output transducer two (X, Y-axis) angle value with respect to the horizontal plane, sensor output voltage analog quantity is led to
Cross after A/D conversions and be sent to MCU.If above-mentioned vehicle traveling decision circuitry overload restriction system is entered in vehicle travel process to it
Lotus detects, after MCU judges overload of vehicle, limiting performing module will make corresponding measure, so certainly will be to traffic safety
Bring very big impact.And vehicle can have in the process of moving many vibrations, goods is in overweight or mistake on leaf spring
Weight state, so as to the numerical value that LOAD CELLS is measured will be bigger than normal or less than normal.Based on both the above influence factor, overload limits system
Must judge whether vehicle travels before system work.The ultimate principle of vehicle traveling decision circuitry is Hall effect, and Hall effect is
Refer to when semiconductor membrane or metal are inserted in magnetic field, when having electric current by semiconductor membrane gold, can be perpendicular to electric current and magnetic field
Direction on produce induction electromotive force.Hall revolution speed transducer is mainly by permanent magnet gear (being arranged on power transmission shaft), Hall unit
Part and associated electronics etc. are constituted.When the vehicle is still, vapour power transmission shaft does not turn, and will not be changed by the magnetic flux of Hall element,
Now vehicle traveling decision circuitry exports TTL low levels, and single-chip microcomputer judges that vehicle is not travelled, the collection of data of going forward side by side.Work as vehicle
During traveling, vapour drive axis, by the magnetic meeting alternate of Hall sensor, when now vehicle is travelled, vapour drive axis lead to
The magnetic flux meeting alternate of Hall sensor is crossed, now, vehicle traveling decision circuitry output TTL high level, single-chip microcomputer judges vehicle
In traveling, overload monitoring works with system halt is limited.Although above-mentioned body oscillating decision circuitry vehicle traveling decision circuitry oneself
Jing judges the transport condition of vehicle, but for goods, even under dead ship condition, goods there is also micro- before starting after loading
It is little to shake, will now impact be produced on the measurement of LOAD CELLS, so to carry out vibration detection after goods is loaded.Car body shakes
Dynamic decision circuitry be arranged on body bottom, vibrating sensor from 801S vibration detections probe, its advantage be vibration detection wide ranges,
Directionless restriction, and sensitivity can be by circuit control.The principle of this body oscillating decision circuitry is exactly, when car body has vibration,
Output height is put down to MCU, and MCU carries out dynamic weighing, and low level is exported when vibrating sensor is not detected by MCU, and MCU is carried out
Static weighing.Overload monitoring modular is mainly responsible for the collection of each sensing data, vehicle full payload and axle and calculates each sensing of aobvious duty
The collection of device data, vehicle full payload and axle calculate, show measured value, judge overload of vehicle situation and control limits module.
As shown in Fig. 2 a kind of bogie overload limits systematic difference, it is specific as follows：(1) initial SBR；(2)
Whether route protection observation circuit there is exception；(3) when normal, judge that this weighs the load for obtaining for vehicle static load,
If vehicle is under steam, LCD MODULE shows " traveling ", and MCU does not make a decision；(4) if vehicle is sentenced not in traveling
In the reasonable scope whether disconnected Vehicular vibration；If 1) not in the reasonable scope, LOAD CELLS, angular transducer collection signal
Send MCU process to；2) MCU calculates vehicle transient state axle load, transient state full payload, and multilevel iudge overload condition；3) MCU is by information
It is sent in LCD MODULE, shows road grade angle, shows that transient state full payload, axle carry display overload condition；4) thus, sentencing

The design principle of the present invention：Vehicle weighing is that carrying goods transfinites the main contents of system processed, only in correct amount
Under the premise of wagon load, accurately whether automobile overload can be judged.Car load analysis is weighed most for vehicle-mounted
Important, car load analysis includes static and moves important, and car load analysis includes static and dynamic.1) vehicle static load point
Analysis.Assume stationary vehicle on the face at road grade angle.2) vehicle dynamic load analysis.To understanding after principle analysis of weighing, car
Larger is affected on the accuracy weighed along the displacement on vertical road surface direction, and cause vehicle to produce along vertical road surface direction
The principal element of displacement is exactly to vibrate.Causing the factor of Vehicular vibration mainly has, and vehicle is caused due to itself various factors
What vibration, the vibration that produced by rough road surface of vehicle and road surface and vehicle were produced by coupling effect shakes
It is dynamic.As can be seen here, it is difficult to which quantitative Analysis are carried out to the impact that vibration is caused.And if detected simultaneously when static in view of vehicle
Do not overload, but because high vibration produces moment weight state in vehicle travel process, now overload monitoring system is possible to
Judge overload of vehicle, and make corresponding treatment measures, so can bring huge hidden danger to traffic safety, so overload
Monitoring system must carry out overload monitoring when stopping.Although vibration has a certain impact to weighing precision, can not will be
System is designed to vehicle has vibration constantly just not work, and this is to prevent some truck men from entering luggage to idling car.So
The system of this programme is designed to when vehicle is travelled not carry out vehicle overload monitoring, but vehicle idling with during continuous loading to car
Traveling carries out state and weighs, it is to be appreciated that because interference of shaking in dynamic weighing is than larger, so the steady load measured of dynamic
Not as overload of vehicle judgment basis, system is needed to take corresponding measure control to make it surely carry out static weighing again so as to judge to surpass
Load situation.Ability is entered Mobile state and is claimed to it when being limited system only when vehicle idling or continuously filled due to the overload of this programme design
Weight, so dynamic steady data processing method selects mean value method because this side is simple, and in vehicle idling precision compared with
