Description of the drawings
Fig. 1 is the structural representation of the multifunctional vehicle mounted overload monitoring system of the embodiment of the present invention.
Specific embodiment
Below according to accompanying drawing 1, presently preferred embodiments of the present invention is provided, and be described in detail, make to be better understood when this The function of invention, feature.
Refer to Fig. 1, a kind of multifunctional vehicle mounted overload monitoring system of the embodiment of the present invention, including:An at least ultrasonic wave Sensor 1, a load measuring device 2, a temperature sensor 3, a communicator 4, a handheld device 5 and a satellite positioning module 6.Wherein, temperature sensor 3, load measuring device 2 and communicator 4 are fixed on a car body (not shown), supersonic sensing Device 1 is fixed on a suspension of car body, ultrasonic sensor 1 and temperature sensor 3 respectively with the communication link of load measuring device 2 Connect, load measuring device 2 is by communicator 4 and the (not shown) communication connection of 5 and one Surveillance center of handheld device.Satellite The position connection communication device 4 of module 6.
Ultrasonic sensor 1 is used to earthward launch ultrasonic wave and acceptance will from after the ultrasound feedback signal of ground return Ultrasound feedback signal is sent to load measuring device 2.Temperature sensor 3 is used to measure real time temperature, and by the temperature for measuring Send load measuring device 2 to.Load measuring device 2 is led to by ultrasound feedback signal of change suspension and the distance on ground Excess temperature degrees of data, to result of calculation temperature-compensating is carried out, and so as to obtain the accurate distance between suspension and ground, circulation is constantly surveyed Amount can calculate the variable quantity of distance, by the load that automobile is drawn by the range information for integrating each ultrasonic sensor 1 Weight.Load measuring device 2 is communicated to connect by communicator 4 with handheld device 5, can calculate the carload lot for obtaining Handheld device 5 is sent in real time so that user can easily know the load condition of Current vehicle, and can be in overload of vehicle Play a part of prompting.Load measuring device 2 is communicated to connect by communicator 4 and Surveillance center so that Surveillance center can be with Load condition to being provided with the vehicle of the present invention carries out monitor in real time, and when finding that vehicle has overload phenomenon warning can be sent Signal requires that car owner processes overload problems to the corresponding handheld device 5 of vehicle, and vehicle letter is sent when car owner does not actively perform Cease and processed to related functional department.Satellite positioning module 6 is used to provide the satellite location data of vehicle.
In the present embodiment, handheld device 5 includes a signal receiving device, a single-chip microcomputer and an audible-visual annunciator (in figure not Show), signal receiving device and audible-visual annunciator connection single-chip microcomputer.Single-chip microcomputer adopts STM32F103RBT6 single-chip microcomputers.Signal is received Device is used for the signal for receiving communicator 4 or outside Surveillance center, and audible-visual annunciator is used to receive the control of single-chip microcomputer and sends Sound and light alarm signal.
Handheld device 5 also includes a display, display connection single-chip microcomputer.Display is used to show the real-time load-carrying of vehicle Situation and temperature information.In the present embodiment, display adopts LCD display.
The present invention does not require that vehicle stops or keeps running at a low speed, such that it is able to not affect highway transport vehicle to pass through On the premise of efficiency, integrated use Dynamic Weighing Technology weighs the weight at the multiple positions of vehicle body, then calculates vehicle body and integrally weighs Amount, then will calculate vehicle load situation and overload condition is sent to the hand of driver using wireless data transmission technology Holding equipment 5, makes driver very clear, can be combined with data high-speed collection and process skill in Big Dipper location technology and 4G networks Art, by vehicle location, testing vehicle register and vehicle load situation remote transmission to Surveillance center.
The operation principle of the present invention is as follows:
When vehicle load, tire is under pressure can deform, while leaf spring can also occur elastic deformation, therefore lead Cause the distance between vehicle bridge and ground to shorten, by measuring this distance change amount can release automobile loading capacity.From on mechanics Analysis, its principle is simpler:Leaf spring is fitted between body of a motor car and wheel shaft, leaf spring has as spring is absorbed There is good damping performance, its stress is linear with deformation, and coefficient of elasticity is constant C.This has circuit design Feasibility, as long as the distance change measured between vehicle bridge and ground can indirectly measure the loading capacity of automobile.Therefore ultrasonic wave is passed Sensor 1 is arranged on the suspension of car body, and ultrasonic sensor 1 earthward sends ultrasonic signal constantly, then detect after upper electricity The ultrasound feedback signal that ground returns, is then measured ultrasound feedback signal transmission by load-carrying to load measuring device 2 The timer on microcontroller inside device 2 measures the pulsewidth of the signal, and ultrasonic wave is obtained by the time for being transmitted into return, Then the real time environment temperature that combination temperature sensor 3 is measured is needed, the real time environment temperature for equally measuring temperature sensor 3 Data are transferred to load measuring device 2, merge it is temperature compensated after the velocity of sound, such microcontroller just can calculate vehicle bridge with The accurate distance on ground, circulation constantly measures the variable quantity that can calculate distance, by integrating each ultrasonic sensor 1 Range information can draw the loading capacity of vehicle.
After obtaining the loading capacity of vehicle, on the one hand measurement result is sent to by way of RF wireless communication driving Room handheld device 5, and given on LCD display in the lump using the RTC functions acquisition time inside STM32F103RBT6 single-chip microcomputers To show in real time, driver is allowed it will be seen that loading capacity and the time of vehicle, when overload of vehicle, driver's cabin handheld device Audible-visual annunciator work above 5, reminds driver's vehicle to overload, and loses no time to take measures.On the other hand measurement result is led to The mode for crossing RF wireless communication is sent to communicator 4, and the connection satellite positioning module 6 of communicator 4 obtains location information, defends Star locating module 6 can adopt Big Dipper UM220, after integration big-dipper satellite location information, by 4G Wi-Fis prison is sent to Control center, reaches the purpose of monitor in real time vehicle, when Surveillance center monitors vehicle overload behavior, can send police Show signal to driver's cabin handheld device 5, warning driver's vehicle has overloaded, and please take measures, if driver does not listen, monitors Center sends a signal to nearest charge station, and charge station can take measures.Same Surveillance center can monitor overloaded vehicle Path behavior, is that the overload of vehicle behavior of optimization improvement below is laid a solid foundation.
When the present invention solves existing monitoring automobile scenarios, the present invention need to be only arranged on various by ageing low problem On goods carrying vehicle, you can directly measure loading capacity, any structure member of vehicle is varied without, reliability is high, and stability is strong, and Cost is relatively low, realizes the dynamic real-time monitor of vehicle load, can be widely applied to the fields such as logistics and highway administration.
The present invention is described in detail above in association with accompanying drawing embodiment, those skilled in the art can be according to upper State and bright many variations example is made to the present invention.Thus, some of embodiment details should not constitute limitation of the invention, this Invention is by the scope defined using appended claims as protection scope of the present invention.
