Summary of the invention
The object of the present invention is to provide a kind of detection and fender guard that can accurately, stably detect the fixed hooks on train of dead hook between railway carriage.The present invention mainly is a kind of based on the laser reverse Engineering Technology, judges whether to exist the fixed hooks on train of dead hook phenomenon to detect and fender guard through the shape that connects airduct between two joint compartments.
Method of the present invention mainly is:
1, gather the airduct data: a certain fixed position, side of direct of travel is provided with laser sensor before railway carriage gets into dump house; Optimal location is between the 3rd joint and the 4th joint compartment; So both given and detected the data processing time that control computer leaves abundance, do not influenced the processing of following detection and dead hook phenomenon again.For guaranteeing to obtain the validity of data, be provided with protective case in above-mentioned laser sensor outside, degree of protection is at least IP65, to prevent the sleet dust storm it is damaged.
2, data handing: after the sensor obtains the airduct outline data collection between the adjacent two joint trains; Be delivered to and detect in the control computer; This detects control computer and adopts Kalman filtering algorithm; The data extract of describing the airduct characteristic between adjacent two compartments is come out; And judge it is dead hook or hook alive according to the characteristic of its distortion; The hook of living in this way then continues to detect next joint compartment; Dead in this way hook then detects control computer promptly to the operator's compartment signal that gives the alarm; Operating personal can adjust accordingly the compartment overturning in proper order, avoids having an accident.
The present invention compared with prior art has following advantage:
1, the used laser sensor of the present invention is that working temperature range is wide; And under the effect of protective case; Guaranteeing it can realize detecting accurately under various weathers and illumination condition; The result is stable, cost is low, the influence of having avoided the collimation error that staff's range estimation brings and other human element to bring.
2, can accurately extract the data that characterize the airduct characteristic according to Kalman filtering algorithm from data centralization; Can detect dead hook fault apace according to the airduct distortion character; And in time feed back to operator's compartment, so this method plays warning and the protective effect that prevents that gib head from being damaged by tipper again.
3, seamless link, this device adopts mode and the existing control system seamless link of OPC, testing result can be sent to operator's upper computer in real time; The mode operator notified that employing sound, light are reported to the police; The staff need not go out the scene, the service conditions of not only having improved, and safety of operation.
Description of drawings
Fig. 1 is a simplified schematic diagram of the present invention.
Drawing reference numeral: 1-front compartment, the gib head between 2-two compartments, the airduct between 3-two compartments, 4-trunk, 5-protective case, 6-laser sensor, 7-detection control computer.
The specific embodiment
Do below in conjunction with 1 couple of the present invention of accompanying drawing and to further describe.In the simplified schematic diagram of the detection of fixed hooks on train shown in Figure 1 and fender guard, the airduct that connects them is arranged between two compartments.The side of direct of travel and compartment are provided with laser sensor apart from the position (particular location need calculate according to railway carriage length and dump house structure) that is about 5 meters before railway carriage gets into dump house, and this fixed position is the position between the 3rd joint and the 4th joint compartment just.Be provided with protective case with thermostatic control function and rain brush in the outside of above-mentioned laser sensor.Above-mentioned laser sensor obtains the consecutive numbers strong point that connects airduct, and the mode of analog quantity is sent in the detection control computer by communicating by letter perhaps, in detecting control computer, uses Visual C++ coding to be used for the data of obtaining are analyzed.At first adopt Kalman filtering algorithm, reject the invalid data of data centralization.According to priori datas such as compartment, wheels, find data initial point and terminating point between the two joint compartments then, data point is carried out fuzzy clustering, and self adaptation calculates threshold value, judge whether cluster centre shows the airduct deformation that is distorted.Surpass 25% if judge the probability of airduct twist distortion, illustrate that then estimative gib head is dead hook; Otherwise, then be the hook of living.The hook of living in this way then continues to detect next joint compartment, and dead in this way hook then detects the mode of control computer through OPC, and promptly to the operator's compartment operator interface signal that gives the alarm, operating personal can adjust accordingly the compartment overturning in proper order, avoids having an accident.Live hook or dead hook are judged in distortion according to airduct, and its difficult point is that train one moving speed is fast, in the continuous movement process, detects thousands of point data, needs therefrom to extract the data of describing the airduct shape fast and judges.In order to address this problem, adopt Kalman filtering to send out data are carried out pretreatment, reject invalid data.The design adaptive algorithm is confirmed threshold value, carries out fuzzy clustering to handling the back data, judge to such an extent that whether discharge pipe has distortion character, and then whether draw is the conclusion of dead hook.
