Background technology
" about the whole nation, carrying out the embodiment of the work of vehicle overload overload managing " assigned by China central seven ministries and commissions such as the associating Ministry of Public Security, the Committee of Development and Reform, State Administration of Quality Supervision, Inspection and Quarantine, national security production office, industrial and commercial administration general bureau, State Council Legislative Affairs Office that started to be taken the lead by national communication portion in 2004.To the effective monitoring of vehicle enforcement and the law enforcement evidence obtaining of operation, be so how the current major issue facing, design beyond doubt the most effective solution route of a high efficiency vehicle-mounted weighing monitoring device, can also and meet the demand of driver individual grasp Weight Loaded as the logistics transportation management and running of enterprise simultaneously.
Mainly there is following problem in the existing vehicle-mounted product of weighing: weighing precision is low, and weight is affected greatly by external interference; Installation of sensors trouble; Bus communication does not meet vehicle-mounted product requirement, and communication efficiency is low, poor reliability.
Summary of the invention
The object of this invention is to provide a kind of Onboard weighing device based on CAN bus, this device is connected LOAD CELLS by CAN bus with controller, and CAN bus hardware is fault-tolerant, favorable expandability, and reliability is high, and communication efficiency is high; Adopt brake signal detecting sensor to judge accurately vehicle-state by subcontrol, it is more accurate to make to measure simultaneously.
To achieve these goals, the present invention has adopted following technical scheme: a kind of Onboard weighing device based on CAN bus, comprise and be installed on the controller of pilothouse and be located at a plurality of LOAD CELLS on vehicle axle housing, described controller is connected respectively with a plurality of LOAD CELLS by CAN bus, described CAN bus one end is connected with controller, the other end is connected with brake signal detecting sensor, on described controller, is connected with display.
Further, on described controller, be connected with DTU module.
Further, described DTU module and display are all positioned at pilothouse.
Further, described LOAD CELLS is CGWY03 type LOAD CELLS.
Beneficial effect of the present invention is: use after said structure, by CAN bus, LOAD CELLS is connected with controller, CAN bus hardware is fault-tolerant, favorable expandability, and reliability is high, and communication efficiency is high.And controller is connected with brake signal detecting sensor by CAN bus, brake signal detecting sensor is used for judging the brake of vehicle, and send controller to by CAN bus, algorithm in subcontrol accurately moves, improve measuring accuracy, during vehicle static, weighing precision is ± 3%, and in the time of dynamically, weighing precision is ± 5%.Meanwhile, this device is installed simple, is easy to safeguard.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention technical scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that the present invention is in order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
A kind of Onboard weighing device based on CAN bus as shown in Figure 1, comprise and be installed on the controller 1 of pilothouse and be located at a plurality of LOAD CELLS 3 on vehicle axle housing, LOAD CELLS 3 is directly installed on the axle housing of automobile shafts, for responding to the deformation of axle housing after stressed, digitized processing through LOAD CELLS 3, can quantize the deformation quantity of axle housing, this deformation quantity is sent to controller 1 by CAN bus 2.The nucleus module that controller 1 is this weighing device, the data of reception LOAD CELLS 3, calculate weight by algorithm process.The object of algorithm process is the interference sections filtering out in sensor signal, and the stressed variation of judgement vehicle axle housing is the effect of external force during from the deadweight of goods or from vehicle operating, improves the precision of weighing.
Described controller 1 is connected respectively with a plurality of LOAD CELLS 3 by CAN bus 2, and CAN bus 2 is guarantees of reliable signal transmission between controller 1 and LOAD CELLS 3; Described CAN bus 2 one end are connected with controller 1, and the other end is connected with brake signal detecting sensor 4, on described controller 1, are connected with display 5.This display 5 is for showing weighing results and response user's operation.Brake signal detecting sensor 4 is used for judging the brake of vehicle, by CAN bus 2, passes to controller 1.Algorithm in subcontrol 1 accurately moves, and improves measuring accuracy.By CAN bus 2, LOAD CELLS 3 is connected with controller 1, CAN bus 2 hardware fault-tolerants, favorable expandability, reliability is high, and communication efficiency is high.During vehicle static, weighing precision is ± 3%, and in the time of dynamically, weighing precision is ± 5%.Meanwhile, this device is installed simple, is easy to safeguard.
Position and number needs that LOAD CELLS 3 is installed determine that according to the quantity of axle for vehicle the precision of sensor itself and installation site all can affect weighing precision, therefore, position and quantity that LOAD CELLS 3 is installed are of crucial importance, and LOAD CELLS 3 is installed too much, and cost is high; LOAD CELLS 3 is installed very few, and weighing precision is low.Take six-axle car as example, near on three axles of headstock, two LOAD CELLS 3 are all being installed, the symmetrical both sides that are installed on axle, can gather axle deformation quantity so more accurately respectively; On three axles away from headstock, a LOAD CELLS 3 is all installed, is all positioned at the center of axle.
Wherein, on described controller 1, be connected with DTU module 6.DTU module 6 is responsible for vehicle monitoring data to send to control center by GPRS network, and control center can telemonitoring and control native system.
Wherein, described DTU module 6 and display 5 are all positioned at pilothouse, and convenient operation and control are easy to use, are beneficial to maintenance.
Preferably, described LOAD CELLS 3 is CGWY03 type LOAD CELLS.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
