However, due to the limitations of the prior art and equipment, the manual account-setting management mode with original manufacturing, overhauling and flaw detection information of locomotive wheels and the information management mode with independent cutting data are difficult to dynamically predict faults and manage health of all locomotive wheels. For example, the wheel inspection of locomotive servicing field is mainly performed by manual visual inspection; flaw detection of the overhaul storage is manually operated; when in middle repair and major repair, the manual flaw detection is carried out, and also has equipment and (5) flaw detection. The problems of low automatic flaw detection level, low flaw detection efficiency, easiness in being influenced by the service level of operators, independent detection information of each repair process, no realization of network informatization and the like exist in each stage.

Detailed Description
Illustrative, non-limiting embodiments of the present invention are described in detail below with reference to the accompanying drawings, which further illustrate a locomotive wheel ground identification system and locomotive wheel ground identification method in accordance with the present invention.
Referring to fig. 1, in accordance with one aspect of the present invention, a locomotive wheel ground identification system is presented, the system comprising a plurality of electronic tags, an activation sensor 3 (comprising a first activation sensor 31 and a second activation sensor 32), an antenna set and a control device, wherein the activation sensor 3 and the antenna set are respectively connected to the control device to transmit data to and receive control signals from the control device.
The electronic tags are respectively arranged on the outer side of each wheel of the locomotive and are used for storing various information related to the wheel where the electronic tags are positioned, such as factory information, molten iron proportioning number, manufacturing unit, locomotive information and other data related to the wheel. Preferably, the plurality of electronic tags are UHF passive electronic tags, the passive electronic tags have ultra-wide working frequency and strong anti-interference capability, the identification distance can reach more than 10m, a battery is not needed, and the memory can be repeatedly erased and written for more than 100000 times. In one embodiment, the electronic tags are arranged on the outer circle of the wheel hub of each wheel, and 2 electronic tags are symmetrically arranged on the outer circle of the wheel hub of each wheel, so that when the wheel enters the acquisition area, even if one electronic tag closest to the antenna group leaves the coverage area of the antenna emission angle, the other electronic tag on the symmetrical position can enter the coverage area of the antenna emission angle before the wheel leaves the acquisition area, and the reliable acquisition of the wheel information is ensured. In addition, the two electronic tags are arranged, so that the wheel information can be obtained from one electronic tag when the other electronic tag is lost or invalid, and the reliability of the system is improved.
The start sensor 3 is arranged close to the rail 2 and is used for detecting the driving-in information of the locomotive wheels. When the locomotive enters the acquisition area, the first axle wheel of the locomotive triggers the starting sensor 3, the starting sensor 3 sends a starting signal to the control device, and the control device sends a starting control command to the antenna group according to the starting signal so as to start the antenna group to start scanning operation.
The antenna group is arranged in front of the starting sensor 3 along the running direction and is used for scanning a plurality of electronic tags arranged on wheels. In one embodiment, the vertical distance L1 between the activation sensor 3 and the antenna group is between 1m and 3m, preferably the vertical distance L1 between the activation sensor 3 and the antenna group is 2m. The antenna group comprises a plurality of antennas 51 symmetrically arranged on both sides of the rail 2 between adjacent sleepers 1. The plurality of antennas 51 in the antenna group may transmit radio frequency signals to scan a plurality of electronic tags provided at the outer circumference of the hub of each wheel to acquire wheel information related to the wheel stored in the electronic tags. The plurality of antennae 51 are arranged on the two sides of the steel rail 2, and the electronic tag information can be directly read out of the outer side of the steel rail 2, so that the interference of locomotive equipment on antenna scanning signals is avoided, and the reliability of the system is further improved; by arranging a plurality of antennas 51 between adjacent sleepers 1, the influence of the sleepers 1 on the antenna position can be reduced, the stability of the installation of the antennas 51 can be improved, and the scanning range of the antennas 51 can be enlarged. In one embodiment, each of the plurality of antennas 51 is a transceiver-integrated antenna. Preferably, the antenna group includes 2 antennas to scan two wheels disposed in parallel on the same axle.
The application method of the locomotive wheel ground identification system provided by the invention comprises the following steps: the starting sensor 3 is always in a starting state; after the locomotive enters the acquisition area, a first axle wheel of the locomotive triggers a starting sensor 3, and the starting sensor 3 sends a starting signal to the control device; the control device sends a control command to the antenna group according to the starting signal to start a plurality of antennas 51 in the antenna group; the plurality of antennas 51 sequentially scan a plurality of electronic tags provided on wheels of the locomotive, and transmit scanned wheel information within the scanned electronic tags to the control device; the control device receives the scanned wheel information and uses the scanned wheel information to update the initial wheel information of the corresponding wheel stored in the control device. The ground recognition system for the locomotive wheels adopts the transceiver-integrated antenna to scan a plurality of electronic tags arranged on the excircle of the wheel hub, thereby acquiring information related to the wheels, avoiding the interference of locomotive equipment on antenna scanning signals caused by arranging the antenna 51 on the inner side of the steel rail 2, and improving the reliability of the ground recognition system; the wheel hub excircle is provided with a plurality of electronic tags (for example, 2 electronic tags), so that the condition of missing scanning caused by only arranging one electronic tag can be avoided, and the wheel information can be obtained from the other effective electronic tag when one electronic tag is lost or fails, thereby improving the reliability of the system.
In one embodiment of the invention, the antenna group further comprises a registration sensor 41. The position sensor 41 is disposed behind the plurality of antennas 51 along the running direction of the locomotive and connected with the control device, and can determine the axle position of the current wheel according to the passing times of the wheel, and send the axle position data of the current wheel to the control device, and the control device further correlates and stores the axle position data with the scanned wheel information of the wheel obtained by scanning the antennas. In this way, the locomotive wheel ground identification system correlates the wheel information with the axle position information of the wheel, so that the wheel information is correlated with the subsequent wheel flaw detection information and maintenance information related to the axle position information in a system database, and further the locomotive wheel life management is realized. In one embodiment, the vertical distance L2 between the registration sensor 41 and the plurality of antennas 51 is between 0.5m-1.5m, and more preferably, the vertical distance L2 between the registration sensor 41 and the plurality of antennas 51 is 1.0m.
Referring to fig. 1, a start sensor 3 is provided inside a rail 2 to more accurately detect a wheel. Preferably, the starting sensor 3 comprises a first starting sensor 31 and a second starting sensor 32 arranged in sequence along the direction of travel of the locomotive. Thus, when the control device receives the trigger signal of the first starting sensor 31 and then receives the trigger signal of the second starting sensor 32, the control device can judge that the running direction of the locomotive is the running direction of the locomotive into the acquisition area, and then the control device sends a starting control command to the antenna group; when the control device receives the trigger signal of the second start sensor 32 first and then receives the trigger signal of the first start sensor 31, the control device can judge that the running direction of the locomotive is out of the acquisition area, and the control device does not send a start control command to the antenna group.
In one embodiment, each antenna 51 in the antenna group is angled between 10-50 with respect to the locomotive direction of travel, preferably each antenna 51 is angled at 30 with respect to the locomotive direction of travel. In this way, the upper boundary of the emission angle of the antenna 51 is vertical to the steel rail 2, electronic tag information of other surrounding wheels cannot be read by mistake, and no recognition blind area is ensured when the ground recognition system works. Meanwhile, the angle of inclination of each antenna 51 toward the inside of the track is 10 ° -30 °, preferably, the angle of inclination of each antenna 51 toward the inside of the track is 15 °, so that the antenna emitting area faces the direction of the electronic tag, ensuring reliable identification.
Referring to fig. 1 and 2, the locomotive wheel ground identification system includes a plurality of antenna groups. The plurality of antenna groups are disposed in the front of the start sensor 3 in the traveling direction in order. Thus, when a part of the plurality of electronic tags (for example, the electronic tags 82 and 83) disposed on the outer circle of the hub 81 of a certain wheel 8 is lost or disabled to leave only one valid electronic tag (for example, the electronic tag 82), and the remaining valid electronic tag 82 just leaves the coverage area of the emission angle α of the antenna 51 when the wheel 8 enters the first antenna group acquisition area, that is, the first antenna group cannot identify the electronic tag on the wheel 8 under the extreme condition, in the case of adopting the preferred mounting manner, the locomotive wheel 8 reaches the position just above the second antenna group (for example, including the position sensor 42 and the plurality of antennas 52) disposed in front of the first antenna group along the driving direction, the wheel rotation angle is about 180 °, and the wheel rotation angle is greater than 90 ° in the antenna emission coverage area, one valid electronic tag 82 on the wheel 8 can be scanned, so that all wheel information can still be identified under the worst condition, and the reliability of the ground identification system can be ensured. Preferably, the number of antenna groups is 2. Since the distance between adjacent axles of the locomotive is generally between 1.75m and 2.8m, in order to ensure that the scanning area of at least one antenna group of the adjacent two antenna groups can cover the electronic tag of the wheel, in a preferred installation mode, the vertical distance L3 between the adjacent two antenna groups of the plurality of antenna groups is set to be 1m to 3m, and more preferably, the vertical distance L3 between the adjacent two antenna groups of the plurality of antenna groups is set to be 2m.
Referring to fig. 1, the system further comprises a stop sensor 7 connected to the control device. The stop sensor 7 is disposed in close proximity to the rail 2, and the stop sensor 7 is disposed in front of the antenna group in the running direction of the locomotive.

The control means receives a first activation signal from the first activation sensor 31 later than a second activation signal from the second activation sensor 32, the locomotive is in a driving state of exiting the acquisition area, so that the control device does not start the antenna group. After the control device receives the first starting signal sent by the first starting sensor 31 before the second starting signal sent by the second starting sensor 32 and starts the antenna group, the control device receives the second starting signal sent by the second starting sensor 32 again before the first starting signal sent by the first starting sensor 31, so that the locomotive runs reversely when the locomotive does not completely leave the collecting area after entering the collecting area, and under the condition that the ground identification system does not collect all wheel information of the locomotive, the control device clears the wheel information of the locomotive wheels collected by the antenna group. The signals of the first starting sensor 31 and the second starting sensor 32 can accurately judge the running direction of the locomotive and accurately judge whether the wheel information is effectively collected, so that the reliability of the wheel ground identification method is improved.
In one embodiment, each antenna 51 in the antenna group is angled between 10-50 with respect to the locomotive direction of travel, preferably each antenna 51 is angled at 30 with respect to the locomotive direction of travel. In this way, the upper boundary of the emission angle of the antenna 51 is vertical to the steel rail 2, electronic tag information of other surrounding wheels cannot be read by mistake, and no recognition blind area is ensured when the ground recognition system works. Meanwhile, the angle of inclination of each antenna 51 toward the inside of the track is 10 ° -30 °, preferably, the angle of inclination of each antenna 51 toward the inside of the track is 15 °, so that the antenna emitting area faces the direction of the electronic tag, ensuring reliable identification.
In one embodiment of the present invention, the antenna group further includes a gauge sensor 41, the gauge sensor 41 is disposed behind the plurality of antennas 51 in the direction of travel of the locomotive, and the gauge sensor 41 is connected to the control device. When the locomotive wheel triggers the position sensor 41, the position sensor 41 can determine the axle position of the current wheel according to the passing times of the wheel, and send the axle position information to the control device as the scanning axle position data of the current wheel. Thus, the step of the antenna group transmitting scanned wheel information of the first axle wheel to the control device further includes the following steps.

In this case, a plurality of initial wheel information is sequentially updated using a plurality of scanned wheel information.
The collection sequence of the plurality of scanning wheel information is opposite to the arrangement sequence of the plurality of initial wheel information, and the plurality of scanning wheel information is the same as the plurality of initial wheel information, so that the locomotive is driven into the collection area in a mode of reverse axle number sequence, and the wheels of all axle positions of the locomotive are not replaced or exchanged. In this case, the plurality of initial wheel information is reversely updated using the plurality of scanned wheel information.
The acquisition sequence of the plurality of scanning wheel information is partially the same as the arrangement sequence of the plurality of initial wheel information, and the plurality of scanning wheel information is the same as the plurality of initial wheel information, so that the wheel exchange is performed among part of axle positions of the locomotive, but a new wheel is not replaced. In this case, a plurality of initial wheel information is updated using a plurality of scanned wheel information, and the server issues an alarm to prompt the relevant person to check.
The acquisition sequence of the plurality of scanned wheel information is partially the same as the arrangement sequence of the plurality of initial wheel information, and the plurality of scanned wheel information is partially different from the plurality of initial wheel information, which indicates that a part of the axle position of the locomotive is replaced with a new wheel. In this case, a plurality of initial wheel information is updated using a plurality of scanned wheel information, and the server issues an alarm to prompt the relevant person to check.
Some of the plurality of scanning axle position data have no scanning wheel information associated therewith, indicating that the electronic labels of the wheels of these axle positions are all missing. In this case, the server issues an alarm to prompt the relevant personnel to check.
In one embodiment, the locomotive wheel ground identification method further comprises a stop sensor 7 coupled to the control device. The stop sensor 7 is disposed in close proximity to the rail 2, and the stop sensor 7 is disposed in front of the antenna group in the running direction of the locomotive. Thus, the locomotive wheel ground identification method further comprises the steps of: when the last axle wheel of the locomotive triggers the stop sensor 7, the stop sensor 7 sends a stop signal to the control device; the control device sends a stop signal to the antenna group to stop the operation of the antenna group. In addition, when the locomotive enters the collection area in the reverse direction, the stop sensor 7 is first triggered and sends a signal to the control device, in which case the control device determines that the locomotive enters the collection area in the reverse direction and does not activate the antenna group. From the above description, it can be seen that the energy saving purpose can be achieved by providing the stop sensor in the locomotive wheel ground recognition system.
