Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of an abnormality determination method based on a multi-wire four-wheel positioning detection device according to an embodiment of the present invention, and as shown in fig. 1, the abnormality determination method based on a multi-wire four-wheel positioning detection device according to the embodiment includes:
step S110, receiving four-wheel positioning measurement data sent by four-wheel positioning detection devices on at least two same detection lines in the multi-line detection lines, respectively.
The abnormity determination method based on the multi-line four-wheel positioning detection equipment provided by the embodiment of the invention is applied to the detection line in the vehicle automatic production line, wherein the detection line is a multi-line, namely comprises at least two same detection lines. The detection line in the vehicle production line is used for detecting all kinds of vehicles which are produced so as to ensure that all kinds of performances of the vehicles which are produced reach the preset standard. The vehicle testing comprises four-wheel positioning testing, when the vehicle to be detected reaches a four-wheel positioning testing station on the detection line, the four-wheel positioning detection equipment carries out four-wheel positioning detection on the vehicle to be detected and outputs four-wheel positioning measurement data. However, the four-wheel positioning detection device may gradually generate errors in the long-term use process, so that the accuracy of the four-wheel positioning measurement data is affected. At present, in order to ensure the precision of four-wheel positioning detection, each four-wheel positioning detection device on a detection line is regularly maintained, and the four-wheel positioning precision is verified. However, in the current regular maintenance mode, it is difficult to ensure that the measurement accuracy of the four-wheel positioning detection device fluctuates due to various factors in the use process, so that the four-wheel positioning detection accuracy of the vehicle may still be affected.
In order to solve the above problem, an abnormality determination method based on a multi-line four-wheel positioning detection device according to an embodiment of the present invention is that, when a detection line of a vehicle detects four-wheel positioning of the vehicle, the four-wheel positioning detection device on the detection line sends data detected each time to a unified data processing device, such as a control server of the detection line. The data processing equipment is used for continuously receiving four-wheel positioning measurement data sent by each four-wheel positioning detection equipment of the multi-wire detection line and storing the four-wheel positioning measurement data. For the compound line detection lines, each detection line is provided with four-wheel positioning detection equipment, and then the four-wheel positioning detection equipment on each detection line can send a detection result to the unified data processing equipment.
In an embodiment, detection logs sent by four-wheel positioning detection devices on at least two same production lines in a multi-line production line can be received respectively, and the detection logs comprise four-wheel positioning measurement data. In order to facilitate management, currently, a centralized data processing device stores a detection log of each four-wheel positioning detection device, and the detection log at least includes four-wheel positioning measurement data detected by each four-wheel positioning detection device each time, so that the detection log of each four-wheel positioning detection device can be analyzed, and thus an abnormality determination based on a multi-line four-wheel positioning detection device can be performed. When the anomaly determination method based on the multi-wire four-wheel positioning detection device provided by the embodiment of the invention is applied to the data processing device for receiving the four-wheel positioning measurement data sent by the four-wheel positioning detection device, an independent anomaly determination module can be configured in the data processing device, the anomaly determination module can be formed by software or hardware, and the anomaly determination module acquires the detection log of each four-wheel positioning detection device from the data processing device. Or an independent device for judging the abnormality of the four-wheel positioning detection device can be arranged, wherein the device is independent of the data processing device and connected with the data processing device, and receives the detection log of each four-wheel positioning detection device sent by the data processing device.
And step S120, when the difference of the four-wheel positioning measurement data sent by the four-wheel positioning detection equipment on different detection lines exceeds a preset threshold value, judging that the four-wheel positioning detection equipment of the compound line production line is abnormal.
In the conventional data processing equipment, only a threshold value of a four-wheel positioning detection result is preset, and when the received four-wheel positioning detection result exceeds the preset threshold value, a prompt message is sent. In the embodiment of the invention, the difference between the four-wheel positioning measurement data sent by the four-wheel positioning detection equipment on different detection lines is judged, and whether the difference is over a preset threshold value is judged. And if the difference exceeds a preset threshold value, judging that the four-wheel positioning detection equipment of the multi-line production line is abnormal. The multiple detection lines on one compound line detection line are completely the same detection line, and the four-wheel positioning detection devices used in the detection lines are also the same, so that the four-wheel positioning measurement data detected by the four-wheel positioning detection devices on the vehicle to be detected are closer, and the difference is within a certain range. And the probability of the simultaneous occurrence of the abnormality of each four-wheel positioning detection device is very low. If the difference between the four-wheel positioning measurement data detected by the four-wheel positioning detection devices on different detection lines of the multi-line detection line is large, it means that the four-wheel positioning parameters of the detected vehicle have problems, or means that the four-wheel positioning detection devices on a certain detection line have problems. Therefore, when the centralized data processing equipment determines that the difference of the four-wheel positioning measurement data sent by the four-wheel positioning detection equipment on different detection lines exceeds a preset threshold value, the four-wheel positioning detection equipment of the multi-line production line is judged to be abnormal.
Furthermore, after the four-wheel positioning detection equipment of the multi-line production line is judged to be abnormal, abnormal alarm information of the four-wheel positioning detection equipment can be sent out, so that production management personnel can know that the four-wheel positioning detection equipment is abnormal, and further can carry out maintenance, calibration and other operations. The alarm information can be sent out by any mode of sound, image, video and the like.
Further, when the difference of the four-wheel positioning measurement data sent by the four-wheel positioning detection devices on different detection lines exceeds a preset threshold, only the four-wheel positioning detection device with one detection line on the multi-line production line is determined to be abnormal, but which four-wheel positioning detection device is not determined, so that the four-wheel positioning measurement data sent by each four-wheel positioning detection device can be further compared with the standard four-wheel positioning measurement data, and the four-wheel positioning detection device with the abnormal position can be accurately determined.
In one embodiment, the difference of the four-wheel positioning measurement data sent by the four-wheel positioning detection devices on different detection lines exceeds a preset threshold, it may be that the four-wheel positioning parameter of the detected vehicle on a certain detection line is abnormal, but not that the four-wheel positioning detection device is abnormal, so that it may be determined that the four-wheel positioning detection device of the multi-line production line is abnormal when the average difference of the four-wheel positioning measurement data sent by the four-wheel positioning detection devices on different detection lines in a preset period exceeds the preset threshold. That is to say, four-wheel positioning measurement data sent by each four-wheel positioning detection device is continuously counted, and an average value of the four-wheel positioning measurement data sent by each four-wheel positioning detection device in a preset period is calculated according to the preset period. The preset period may be, for example, every 4 hours, every day, or any time according to the demand of the device. Or the preset period may also be the number of detections by the four-wheel positioning detection device, for example, every 100 times, every 500 times, etc., as one period. And comparing the average difference of the four-wheel positioning measurement data sent by the four-wheel positioning detection equipment on different detection lines in a preset period, and judging whether the four-wheel positioning detection equipment is abnormal or not according to the average difference.
The anomaly determination method based on the multi-line four-wheel positioning detection device provided by the embodiment receives four-wheel positioning measurement data sent by four-wheel positioning detection devices on at least two same detection lines in the multi-line detection lines respectively; when the difference of four-wheel positioning measurement data sent by the four-wheel positioning detection equipment on different detection lines exceeds a preset threshold value, the four-wheel positioning detection equipment of the compound line production line is judged to be abnormal, the detection precision of the four-wheel positioning detection equipment can be constantly monitored in the normal operation process of the compound line detection line, and the detection precision error possibly existing in the four-wheel positioning detection equipment can be found at the first time, so that the quality of vehicles produced on the vehicle production line is improved, and the working efficiency of the vehicle production line can be effectively improved.
