Embodiment
As shown in Figure 3; The non-at-scene enforcement system of the overload of vehicle of present embodiment comprises: on-the-spot weighing instrument 1000, a plurality of weighing platform (101a; 101b, 101c), signal gathering unit 102, vehicle separative element 103, fetalism recognizer 106 (optional), video monitoring device 200 and non-at-scene law enforcement server 300.On-the-spot weighing instrument 1000 can comprise: data processing unit 104 and data transmission unit 105.
Non-at-scene law enforcement server 300 can be connected with on-the-spot weighing instrument 1000 and video monitoring device 200 through LAN or public network.
Weighing platform can be realized the technology type of vehicle dynamic function of weighing for any one; For example can be: weighting platform, bent plate, car load scale etc.; Weighing platform is arranged on the monitoring track with certain layout type, is used for vehicle dynamic and weighs, when vehicle passes through weighing platform; Be arranged on sensor (1011a, 1011b) the corresponding vehicle weight signal of generation on the weighing platform.
The situation of 3 weighing platforms though in Fig. 3, given an example uses several weighing platforms need calculate acquisition in the reality.For example, as shown in Figure 4, use 5 platforms totally 10 bent plates be arranged on the monitoring track with certain layout type, be used for vehicle dynamic and weigh, vehicle during through weighing platform sensor produce corresponding vehicle weight signal.
The principle of accurately weighing when vehicle is current at a high speed is: according to existing theory, in the vehicle ' process, the formula of ground pressure is approximately:
A wherein
0The actual weight of expression vehicle, A
1The weight change amplitude of expression vehicle vibrations, ω representes the frequency that shakes,
The phase place of expression vibrations.
Because the approximate form that is just showing as (surplus) chord curve of vehicle ground pressure; Therefore in the vehicle operating process; If can collect the continuous data that surpassed for 1/2 cycle; Then can effectively utilize the actual ground pressure that the semiperiod method draws vehicle, the semiperiod method effectively obtain actual weight precision 5% with interior degree of confidence more than 95%.Under the fast state; Still meet above-mentioned rule in the vehicle traveling process; But because car speed is high, the ground pressure data that single weighing platform is sensed are few, can't reach requirement; Can not effectively calculate wheel weight, therefore through using effectively pressure boost data of a plurality of weighing platforms through the semiperiod.
The length of effectively weighing of supposing single weighing platform is L, and the staggered distance of weighing platform is X, and the ground contact length of vehicle tyre is l; The travel speed of vehicle is V, and the vibrations cycle of vehicle is T, for reaching the purpose of gathering enough data; The weighing platform quantity that needs to use is N, and following formula is then arranged:
Promptly need weighing platform quantity N to be:
Therefore, under the speed of fast state such as 80km/h, vibration frequency is about 5Hz, and then the vibrations cycle is 0.2s, and staggered layout distance is 0.3m for 300mm, and the bent plate weighing platform length of effectively weighing is that 500mm is about 0.5m.Add up according to historical data; The degree of confidence that the ground contact length of vehicle tyre is no more than 250mm surpasses 95%; Therefore suppose that the ground contact length of vehicle tyre is that 250mm is 0.25m,, promptly need at least 5 weighing platforms effectively to meet the demands through calculating N >=4.344.
When wheel passes through, can obtain ground pressure curve as shown in Figure 5.Owing to use 5 cover weighing platforms, after all platform datas are added up, can guarantee that valid data surpass the vibration period half.In different weighing platforms, choose the some P1, the P2 that find corresponding semiperiod position.Because the approximate form that is just showing as (surplus) chord curve of wheel ground pressure, two point out corresponding pressure is respectively:
The part relevant with phase place of the ground pressure in the moment of two phase phasic difference semiperiods can be cancelled out each other, i.e. formula (6):
So
f(t
1)+f(t
2)＝2×A
0 (7)
Promptly when using the corresponding semiperiod to put, can effectively reduce the interference that out of phase causes the vehicle ground pressure, thereby obtain vehicle weight comparatively accurately.Simultaneously, because the ground pressure of wheel is not just (surplus) chord curve of standard, have certain stochastic error, the point that therefore uses all to satisfy the semiperiod carries out the stochastic error that the multiple spot calculated weight can reduce the result, thereby obtains result accurately.
Through experimental verification; This method effectively obtain actual weight precision 5% with interior degree of confidence more than 96%; And the degree of confidence that the ground contact length of vehicle tyre is no more than 250mm surpasses 95%, therefore uses this method to obtain weighing accuracy and is no less than 90% 5% with interior degree of confidence.
Fetalism recognizer 106 (non-essential), but collection vehicle fetalism signal and pass to on-the-spot weighing instrument 1000.
Vehicle separative element 103 is made up of technology types such as grating vehicle separating device and/or coil vehicle separating devices, can be to on-the-spot weighing instrument 1000 output vehicle separation control signals.
