Abstract
A double-weighing-platform type automotive dynamic weighing system is composed of the following components: automobile separators, a wheel shaft discriminator, a scale frame, a scale platform 1, a scale platform 2, eight bridge type weighing sensors, a controller and an industrial control computer. The automobile separators are equipped at two roadsides of a central line in a driving direction of the scale platform 1. The wheel shaft discriminator is equipped at the road in front of the scale platform 1 in the driving direction. The wheel shaft discriminator and the scale platform are parallel. The controller is equipped at the right roadside of the scale platform 1 and the scale platform 2. The double-weighing-platform type automotive dynamic weighing system is characterized in that: the scale platform is provided with two scale platforms which are independent from each other and are placed in parallel; each scale platform is supported by four bridge type weighing sensors so that all bear force above the weighing platform function four bridge type weighing sensors below. The structure in which the two scale platforms are placed in parallel can effectively reduce vehicle weighing error and improves fault tolerance of the system.
Description
Affiliated technical field
The present invention relates to a kind of road vehicle dynamic weighing field, be specifically related to anti-cheating vehicle dynamic weighing system.
Background technology
At present, the widely used vehicle dynamic weighing system of freeway toll station is comprised of vehicle separator, wheel shaft arbiter, weighing platform, four LOAD CELLS, controller, industrial control computers, can be in the Vehicle Driving Cycle process measuring vehicle weight information, but because the vehicle weight information that sensor collects is subjected to the many impacts in conjunction with the aspect such as standard of whether travelling of car weight, the speed of a motor vehicle, vehicle and weighing platform resonance, mistake car.So existing dynamic weighing system weighting error is larger, particularly under driver's travel situations lack of standardization.
Summary of the invention
In order to solve the problem of large (especially under vehicle travel situations lack of standardization), stability deficiency of existing dynamic weighing system error, the invention provides a kind of pair of weighing platform formula dynamic weighing system, can reduce weighting error, improve stability, even in the situation that lack of standardization the travelling of vehicle also can measure vehicle weight information comparatively exactly.
The technical solution adopted for the present invention to solve the technical problems is: the present invention is comprised of vehicle separator, wheel shaft arbiter, scale frame, weighing platform 1, weighing platform 2,8 bridge type weighing sensors, controller, industrial control computers.Vehicle separator is installed on roadside, weighing platform 1 direction of traffic center line both sides, and the wheel shaft arbiter is installed in the road surface before weighing platform 1 direction of traffic, and Wheel axle identifier and weighing platform keeping parallelism, controller are installed on the roadside, right side of weighing platform 1 and weighing platform 2.It is characterized in that: the weighing platform that two separate and placements arranged side by side are arranged on the scale frame, each weighing platform below is supported by 4 bridge type weighing sensors, on any stressed four bridge type weighing sensors that all act on the below that make weighing platform top, the signal of 8 bridge type weighing sensors is via a weighing platform terminal block that 8 road signals are arranged, be integrated into 4 tunnel weighing-up waves (two paths of signals that the direction of traffic level is adjacent also becomes a tunnel) independently, access respectively four road AD (analog signal conversion is the components and parts of digital signal) of Weighing control instrument.Two structures that weighing platform is placed side by side make the Width of weighing platform originally grow one times, and the elimination vehicle is walked the garages of crossing lack of standardization such as S type, jumping weighing platform, high-speed punching scale and is the impact on weighting error; Because the time of vehicle by weighing platform has increased by 1 times, collectable effective car data of crossing has also increased by one times, can effectively reduce the vehicle weighing error so in addition; Owing to being two independently weighing units, also increased the fault-tolerance of system, when a weighing unit broke down, another weighing unit can work alone, and did not affect normal use.
Principle of work: vehicle sails the track into, and after vehicle separator produced signal, controller began image data; Vehicle is divided by the bridge type weighing sensor of below respectively through weighing station 2,1, two weighing platform of weighing platform successively measures the weight that each beam warp of vehicle is crossed each weighing unit, calculates the speed of Vehicle Driving Cycle according to vehicle by the time of weighing platform and the width gauge of weighing platform in addition; Vehicle moves ahead and presses the wheel shaft arbiter, and the wheel shaft arbiter is differentiated the tire number according to the pressure condition of vehicle tyre, and measures each wheelbase of vehicle and connecting shaft situation in conjunction with the state of weighing platform.Then carry out data by vehicle separator, controller according to above information and process, form the complete car information of crossing, upload to industrial control computer by serial ports.
The invention has the beneficial effects as follows:
1. weighing precision, the data stability than original single table surface weighing system improves a lot;
2. can control effectively that vehicle is jumped in the process of moving weighing platform, walked the S type, the high-speed punching scale, add lack of standardization, the cheatings such as hydraulic means, pading plate;
3. when a weighing unit broke down, another weighing unit can work alone, and did not affect normal use, had strengthened the fault-tolerance of former single table surface weighing system.
