Description
Technical field
The utility model relates to automobile axle load field of measuring technique, particularly relates to a kind of system for detecting transport vehicle axle load distribution condition.
Background technology
At present, all can occur during most commercial transport car lade that car load axle load distributes uneven phenomenon.Car load axle load distributes uneven, certain part of axle is easily made to bear too much load, not only can have an impact to the serviceable life of axle, and the hydraulic performance decline of car load can be made, the wearing and tearing of aggravation tire, reduce the curved characteristic of mistake and the control stability of car load, great hidden danger is brought to the safety traffic of vehicle.
For above problem, existing detection means is for testing loading vehicles by weighing unit or some stands and equipment: measure car load antero posterior axis quality, complete vehicle quality after loading, finally by measurement numerical value, the real-time speed of a motor vehicle, car brakeing parameter etc., judge whether vehicle overloads and whether uneven axle load distributes.These detection methods mostly can only do static measurement, are difficult to measure the axle load change in vehicle travel process, cannot Measurement accuracy and reflect the actual load value born on vehicle every root axle, and waste time and energy, and testing cost is higher.
Summary of the invention
For improving the accuracy that operational vehicle axle load is measured, avoiding causing potential safety hazard because axle load distributes inequality, the utility model proposes a kind of system for detecting transport vehicle axle load distribution condition.
For this reason, the technical solution of the utility model is: a kind of system detected for transport vehicle axle load, it is characterized in that: described system comprises infrared ray sensor, single-chip microcomputer, panel board, GPS, infrared ray sensor is fixedly installed on transport vehicle front-rear axle leaf spring, infrared ray sensor is connected with single-chip microcomputer input port by digital signal wire, single-chip microcomputer output port is connected with panel board, single-chip microcomputer is converted into data falls apart a little by carrying out process to the front-rear axle leaf spring deformation quantity information received, and be X-axis with vehicle commander, overall width is that Y-axis sets up coordinate diagram, loose for described data point is distributed in coordinate axis, contrast in conjunction with each axle rated load of default transport vehicle simultaneously, comparing result is reflected in different colours on the point of the corresponding front-rear axle left and right sides in car load floor map, and shown by panel board, each axle load amount of transport vehicle is judged according to the change of corresponding front-rear axle left and right sides point color, described GPS is connected with single-chip microcomputer input port by digital signal wire, single-chip microcomputer is also integrated with CAN communication module, by CAN communication module, single-chip microcomputer is connected with vehicle-mounted ECU during use.
Principle of work:
During system works, the stress deformation amount of loading vehicles front-rear axle leaf spring is sent to single-chip microcomputer by infrared ray sensor, the deflection of monitoring out is converted into quality by calculation procedure by single-chip microcomputer, and process is converted into a series of data and falls apart a little, be simultaneously X-axis with full car length, car load width sets up coordinate diagram for Y-axis, loose for data point is distributed in coordinate axis.In conjunction with car load planar structure, measurement result is reflected on the point of the front-rear axle left and right sides in car load floor map, and be presented on panel board: if the numerical value calculated is greater than the rated load of vehicle bridge or two ends, left and right difference is excessive, then corresponding in car load floor map on panel board point can become red, now single-chip microcomputer sends " front/rear bridge is overweight; please drive with caution " text prompt by control strategy to panel board, reminds driver to note; If the numerical value calculated is all normal, then the point on panel board in car load floor map is all green.During overload of vehicle, if driver does not take corresponding off-load measure in time, making vehicle bridge keep axle load distributes in uneven state, then single-chip microcomputer is read vehicle current operating conditions by CAN passage, and in conjunction with GPS, vehicle traveling road conditions are judged, in the too high situation of the non-high-speed road conditions speed of a motor vehicle, single-chip microcomputer is limited engine torque and rotating speed by vehicle-mounted ECU, engine speed is reduced and realizes vehicle reduction of speed, ensure the security of vehicle.
Beneficial effect:
The utility model axle load detection system can carry out Measurement accuracy to the axle load of bogie axle each under travel condition of vehicle, and after calculating conversion, result is presented on panel board with the formal intuition of car load floor map, driver is enable to have a clear understanding of the axle load distribution condition of each axle, control test result is corresponding simultaneously sends prompting, so that driver adjusts elimination overloading in time, prevent car load critical component from causing damage because of overweight for a long time, ensure that vehicle safety runs.This system architecture is simple, easy for installation, does not restrict by site condition, and can install and use on dissimilar vehicle, highly versatile, cost is low.
