Description
Technical field
The present invention relates to lorry control technology field, and in particular to a kind of lorry overload protective device.
Background technology
With continuing to develop for China's economy, cargo transport industry is also constantly expanding.However, lorry loading
Overweight is the one of the main reasons that lorry gets into an accident, and transfinites control, mainly leans on now for lorry loading
Lorry opportunity voluntary observance rule should not overload, next to that being detected by the upper road picket of traffic police, but hand over
Jing Shang roads detect that no time and efforts is all detected to all lorries, and many truck men are for money
Interests are taken chances loading of being transfinited in loading, therefore leave many potential safety hazards, easily occur car
Misfortune is dangerous.And in existing weighing system, often because the inclination of vehicle causes weighing results inaccurate,
Error is larger.
The content of the invention
Protected it is an object of the invention to provide a kind of lorry that simple to operate, precision is high, protecting effect is good overload
Protecting system.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of lorry overload protective device,
Including obliquity sensor, pressure sensor, Signal-regulated kinase, CAN, central processing unit, switch,
Display screen, alarm, power amplifier and relay；The obliquity sensor is used to detect lorry inclination angle
Degree, and detection data are transferred to central processing unit by CAN；The pressure sensor is used to detect
Cargo vehicle weight, and detection signal is transferred to Signal-regulated kinase, Signal-regulated kinase is to signal transacting
Central processing unit is transferred to by CAN afterwards, described central processing unit respectively with switch, display screen,
Alarm and power amplifier connection, described power amplifier are connected with relay, and the relay is used for
Control automobile starting ignition coil.
A kind of lorry overload protective device as described above, is further illustrated as described Signal-regulated kinase
Including amplifier and A/D converter, the input of the amplifier and the output end of pressure sensor are connected,
The output end of amplifier and the input of A/D converter are connected, and the output end of A/D converter is total by CAN
Line is connected with central processing unit.
A kind of lorry overload protective device as described above, is further illustrated as the central processing unit is used
C8051F330 single-chip microcomputers.
The beneficial effects of the invention are as follows：Pressure sensor is installed on lorry, during detection signal is delivered in real time
Central processor, central processing unit determines whether lorry transfinites according to detection signal, and is shown by display screen
Come, when goods beyond limitation when, pointed out by alarm, at the same central processing unit send control signal to after
Electrical equipment, so as to control automobile starting ignition coil, forbids lorry to start, and the present invention prevents overloading wagon in time
Operation, it is ensured that personal security and traffic safety, reduces potential safety hazard, easy for installation, simple operation.It is logical
The angle of inclination of host vehicle can be pointed out by crossing obliquity sensor, car owner is adjusted vehicle in time, solved because of car
Inclination makes the problem of weighing results are inaccurate, substantially increases weighing precision.The system is convenient and swift, tool
There is good practicality.
Brief description of the drawings
Fig. 1 is present system structural representation.
Embodiment
Embodiment of the present invention is further elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of lorry overload protective device that the present invention is provided, it is adaptable to which lorry is used.The goods
Car overload protective device include obliquity sensor, pressure sensor, Signal-regulated kinase, CAN, in
Central processor, switch, display screen, alarm, power amplifier and relay.
The obliquity sensor is used to detect angle of inclination of the lorry relative to level ground, and will detect data
Central processing unit is transferred to by CAN, shown after central processing unit processing by display screen；
Using obliquity sensor avoid because lorry tilt and caused by weighting error, reduce ground out-of-flatness to measurement
As a result influence, obliquity sensor is arranged between boxcar and chassis, and obliquity sensor can be using solid
Body pendulum-type obliquity sensor, it would however also be possible to employ liquid pendulum-type obliquity sensor, is not limited here.
The pressure sensor is used to detect cargo vehicle weight, and detection signal is transferred into signal condition mould
Block, pressure sensor is arranged between goods carriage of trucks and cargo car body support plate, and pressure sensor is preferably double cantilevers
Formula pressure sensor, double cantalever type pressure sensor anti-pressure ability is strong, weight capacity is big, anti-side is to impact energy
Power is strong, and is easily installed；It can be passed according to the pressure of the dead weight different choice different model of vehicle
Sensor.
The Signal-regulated kinase signal that pressure sensor is transmitted is handled after by CAN
Central processing unit is transferred to, described Signal-regulated kinase includes amplifier and A/D converter, the amplifier
Input and the output end of pressure sensor connect, the input of the output end of amplifier and A/D converter connects
Connect, the output end of A/D converter is connected by CAN with central processing unit.Amplifier is used to pass pressure
The signal that sensor is transmitted is amplified processing, and the signal after amplification is transferred into A/D converter, A/D
Converter is used to carry out digital-to-analogue conversion to signal, and the signal after conversion is transferred into centre by CAN
Manage device.
Described central processing unit is connected with switch, display screen, alarm and power amplifier respectively, switch
For starting and closing the system, the system can be made to be in work and inoperative two states.Display screen is used
In display cargo vehicle weight and the angle of inclination of lorry.Described alarm is used to remind driver's goods to surpass
Weight, is pointed out driver.On the one hand the central processing unit is used for what obliquity sensor was transmitted
Inclination data is handled, and lorry angle of inclination is shown by display screen, on the other hand to pressure
The weighing data that sensor transmissions come and the data of setting are contrasted, thus control the action of alarm with
Control signal is sent to show by display screen to power amplifier, and by real-time weighing data.It is described
Central processing unit use C8051F330 single-chip microcomputers.Described power amplifier is connected with relay, and power is put
Big device is used to be amplified processing to the control signal that central processing unit is transmitted, by control signal after processing
Relay is transferred to, relay obtains acting after control signal, so as to control automobile starting ignition coil.
The present invention operation principle be：Inclination angle of the lorry relative to level ground is detected by obliquity sensor
Degree, and show on a display screen after being handled by central processing unit, goods is detected by pressure sensor
Car goods weight, and the weight data of goods is transferred to central processing unit, central processing unit is to transmitting
Goods weight data with setting data contrasted, when lorry does not overload, central processing unit would not
Control alarm action, central processing unit also will not transmission of control signals to power amplifier, when lorry overload
When, central processing unit on the one hand control alarm action while, on the other hand also can transmission of control signals give
Power amplifier, is transferred to relay after power amplifier processing, relay obtains acting after control signal,
So as to control automobile starting ignition coil, at this moment automobile can not just start.No matter lorry overloads or nonoverload,
Central processing unit all can show goods weight by display screen.The system is convenient and swift, with good practicality
Property.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, ability
The various deformations or amendments that field technique personnel can make without creative work are protected by this patent.
