Embodiment
Figure 1 shows that the block schematic diagram of the vehicle-mounted re-detection of the dregs system that the utility model provides.Figure 2 shows that the front view of the vehicle-mounted re-detection of dregs system when using that the utility model provides.Figure 3 shows that the side view of the vehicle-mounted re-detection of dregs system when using that the utility model provides.Please in the lump referring to figs. 1 to Fig. 3.
The utility model provides the vehicle-mounted re-detection of a kind of dregs system, for detection of the load-carrying situation of the railway carriage 5 of dregs car.The vehicle-mounted re-detection of dregs system comprises material sensing unit 1, displacement sensing unit 2 and controller 3.Material sensing unit 1 is arranged at the side of railway carriage 5.Displacement sensing unit 2 is arranged at the below of railway carriage 5.Controller 3 electrically connects material sensing unit 1 and displacement sensing unit 2.
Material sensing unit 1 comprises at least one material sensor 11, and material sensor 11 sends coniform transmitting with the height of materials in the detection railway carriage 5 in the wide-angle scope.Displacement sensing unit 2 comprises at least one displacement transducer 21, and displacement transducer 21 sends the cylindric change in displacement that transmits to detect railway carriage 5.The detection signal that controller 3 reception material sensing units 1 and displacement sensing unit 2 send, the intensity of two kinds of detection signals of comparison, analyzing and processing is to obtain testing result.
In present embodiment, material sensor 11 and displacement transducer 21 are ultrasonic sensor.Yet the utility model is not done any restriction to this.In present embodiment, material sensor 21 is different from material sensor 11, and namely the requirement of material sensor 21 and material sensor 11 and model are all inequality.The sensing range of the reflected signal that the sensing range that transmits that material sensor 11 sends is sent greater than material sensor 21, the accuracy of detection of material sensor 21 is higher than material sensor 11.In other words, material sensor 21 requires performance parameters higher, and material sensor 11 requires investigative range greatly and safeguard structure will be got well.Therefore, material sensor 21 should send cylindric transmitting, and guaranteeing in the set of signals precisely, and material sensor 11 should send coniform signal to reach the height of surveying material in the wide-angle scope and the accumulation degree of material.Preferably, material sensor 21 of the present utility model is for the diameter of Shenzhen Aktiebolaget Leo (SE) Box 941, S-251 09 Helsingborg, Sweden of section is the ultrasonic sensor with stainless steel casing of 35mm, and model is LM-200-003-DAC.
In present embodiment, material sensing unit 1 comprises four or six material sensors 11, and displacement sensing unit 2 comprises four material sensors 21.Yet the quantity of the utility model sensor is not done any restriction.In practical application, when only using a material sensor 11 and a material sensor 21, can find out about cargo dead-weight of railway carriage 5 roughly, for example 30 tons car can be judged the error range about 2 tons substantially.Optimal cases and vehicle have relation, and be general best with 5 ~ 6 material sensors 11 and material sensor 21.But most cases gets final product with 4.
In present embodiment, the dregs car comprises vehicle frame and suspension, and railway carriage 5 is fixed on the vehicle frame, displacement sensing unit 2 be installed on the vehicle frame and detect downwards between vehicle frame and suspension apart from change in displacement.Displacement sensing unit 2 is installed on the vehicle frame, lowers the influence of dirt.Particularly, when the railway carriage 5 of dregs car was zero load, the distance between vehicle frame and the suspension was maximal value at this moment.When the vehicle-mounted goods load-bearing of dregs, because the gravity effect, vehicle frame begins to move down, so the distance between vehicle frame and the suspension shortens.Along with the increase of dead weight capacity, the distance between vehicle frame and the suspension constantly shortens.Material sensor 21 produces corresponding detection signal accordingly by judging the displacement that vehicle frame produces downwards.Yet the utility model is not done any restriction to this.Can be according to the installation site of the structures shape displacement sensing unit 2 of vehicle.In other embodiment, displacement sensing unit 2 can be installed on the suspension and upwards detect between suspension and vehicle frame apart from change in displacement.
The detection signal that 3 pairs of material sensing units 1 of controller of the present utility model and displacement sensing unit 2 transmit carries out analyzing and processing, obtains the load-carrying situation.Particularly, for than low-density cargo, characteristicness is that material sensor 11 has measured sufficiently high material level, and material sensor 21 then has only than small-signal.Serve as the monitoring foundation with the signal of material sensor 11 mainly this moment then.When loading was heavier, material sensor 21 signals were clear strong, and be the observing and controlling foundation with the signal of material sensor 21 this moment then, and the signal that the material sensor 11 of side transmits is only for referencial use.When the material of carrying is wandering shape goods, as sand, thinner when native, the signal of then taking all factors into consideration material sensor 11 and material sensor 21 detects.
In present embodiment, the vehicle-mounted re-detection of dregs system also comprises intelligent vehicle mounted terminal 4, and controller 3 electrically connects intelligent vehicle mounted terminal to transmit testing result.In practical application, controller 3 can transfer to intelligent vehicle mounted terminal 4 by network wireless with testing result.4 pairs of testing results of intelligent vehicle mounted terminal are carried out the data processing and are sent to administrative authority, in order to record, analyze, make a strategic decision and dispatch, realize the dynamic remote monitoring.
5% weight change of laden weight for the base model system of 1 to 2 material sensor 11 of configuration and material sensor 21, can be distinguished by the vehicle-mounted re-detection of the dregs that the utility model provides system.For the high-grade system of 4 above material sensors 11 of configuration and material sensor 21, can distinguish 2.5% weight change of laden weight.Than heavy bulk cargo and groceries, the resolution that can distinguish the goods piling height is 3-5mm for gently.
In sum, what the utility model adopted is directly stressed load-carrying detection system of a kind of novel contactless nothing, prolongs the serviceable life of sensor greatly.And can detect the load-carrying situation in real time, thereby find unloading in violation of rules and regulations even the phenomenon of leaking goods effectively.Simultaneously, the utility model carries out analysis-by-synthesis in conjunction with the detection signal of material sensing unit 1 and displacement sensing unit 2, can draw accurate load-carrying testing result, administers the overweight situation of overload effectively.
Though the utility model is disclosed as above by preferred embodiment; yet be not in order to limit the utility model; anyly know this skill person; in not breaking away from spirit and scope of the present utility model; can do a little change and retouching, therefore protection domain of the present utility model is as the criterion when looking claims scope required for protection.
