All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment provides an intelligent monitoring system for rail transportation, which is suitable for an application scene of rail transportation between a mountain top and a mountain foot in the field of rail transportation, and can improve the safety of a transportation locomotive running on a rail.
Referring to fig. 1, a transporting vehicle 1 moves up and down along a track 2 to perform a material transferring work. A number of detection points are provided along the track 2.
The intelligent track transportation monitoring system comprises a plurality of identification cards 3, a plurality of track axle counters 4, a controller 5, a power supply circuit 6, a touch screen 8, a plurality of track axle counters and a warning device 7.
Wherein:
the number of each identification card 3 is different, and one identification card 3 is arranged at each axle of the transport locomotive 1 so as to finish the numbering work of all the axles. For example, 1# identification card numbered 1 is provided at 1# axle, 2# identification card numbered 2 is provided at 2# axle, and 3# identification card numbered 3 is provided at 3# axle … …
And one track axle counter 4 is arranged at each detection point. In this embodiment, the track axle counter 4 is in communication connection with the passing identification card 3 through a near field communication technology, so as to quickly acquire the serial number recorded by the passing identification card 3. Furthermore, the near field communication mode is radio frequency identification, the track axle counter 4 is in radio frequency communication with the identification card 3 through a built-in RFID radio frequency device, the advantages of rapidness and reliability are achieved, detection delay can be effectively reduced, and reliability of data transmission is improved.
The controller 5 is in communication connection with each track axle counter 4, and is configured to receive the number of the identification card 3 fed back by each track axle counter 4, and then make the following three determinations according to the received information:
judging the current position of the transport locomotive 1 according to the number fed back by each track axle counter 4;
for example, if the track axle counter 4 at the detection point No. 1 detects the identification card No. 1, it indicates that the transportation locomotive 1 is passing through the detection point No. 1 at this time; if the track axle counter 4 at the No. 2 detection point detects the No. 1 identification card, the transport locomotive 1 passes through the No. 2 detection point at the moment; by analogy, no enumeration is made.
Judging whether the actual advancing direction of the transport locomotive 1 is consistent with the expectation or not according to the sequence of the identification cards 3 with the same number passing through different detection points;
for example, if 7: 00, the track axle counter 4 at the No. 1 detection point detects a No. 1 identification card, 7: 02, when the track axle counter 4 at the No. 2 detection point detects the No. 1 identification card, the actual movement direction of the transport locomotive 1 is from the No. 1 detection point to the No. 2 detection point, if the actual movement direction is consistent with the expectation, the actual movement direction is not processed, and if the actual movement direction is opposite to the expectation, the actual movement direction is reverse due to unknown conditions, warning information needs to be sent, and a worker is reminded to process the warning information.
And thirdly, judging whether the box is lost or not according to the number of all axles passing through the same detection point within the specified time.
Taking the inspection point # 1 as an example, it is assumed that the transportation vehicle 1 has 10 axles, i.e., 10 identification cards 3 in total, and the time for the transportation vehicle 1 to completely pass through one inspection point is 1 min. Then:
when the track axle counter 4 at the No. 1 detection point detects the No. 1 identification card, timing is started, and within 1min, the number of identification cards 3 detected by the track axle counter 4 at the No. 1 detection point is recorded;
if the number of the detected identification cards 3 is also 10, it indicates that all cars of the transport locomotive 1 are complete and no cases are lost; if the number of the detected identification card 3 is less than 10, for example, 7 or 8, it indicates that the carriage is low and the transport locomotive 1 may lose the carriage when running along the rail.
