[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The Yunba axle counting system provided by the embodiment of the present invention is as follows: Figure 1-Figure 8 As shown,

[0045] An axle counter sensor 10 is installed on the track beam 11, and the axle counter sensor 10 and the guide wheel 12 are located on the same side (that is, the axle counter sensor 10 and the guide wheel 12 are on the same side of the track beam 11). The guide wheel 12 is installed with an axle counter induction plate 13, and the axle counter induction plate 13 is used to cut the magnetic flux lines emitted by the axle counter sensor 10 when the cloud bus passes through the axle counter sensor 10, so that the axle counter sensor 10 generates an analog signal when the cloud bus passes by, wherein at least two axle counter sensors 10 are respectively arranged at both ends of the same detection section;

[0046] The indoor module 20 includes an axle counting host unit 21 for receiving the analog signal, and the axle counting host unit 21 determines whether the state of the detection section is an idle state or an occupied state based on the analog signal;

[0047] The processing module can receive the information that the status of the detection section is idle or occupied from the axle counting host unit 21, and process and output the information that the status of the detection section is idle or occupied. The processing module can also receive and execute a reset instruction (the reset instruction can be manually input into the processing module or input into the processing module from other modules) to prevent certain interference, the first power-on or restart of the system, etc., and execute the reset instruction to avoid causing the detection section to change from a no-vehicle state to an occupied state. In this way, the occupancy state of the section can be accurately detected to ensure driving safety.

[0048] In this technical solution, due to the particularity of the wheels of the Yunba vehicle (rubber wheels), the axle counter sensor cannot count by direct detection. Therefore, an axle counter induction plate 13 is installed on the guide wheel 12. During the operation of the vehicle, the detection plate will sequentially cut the magnetic flux lines 17 of the first detection signal and the magnetic flux lines 17 of the second detection signal of the axle counter sensor, such as Figure 3 As shown, the axle counting system will record the axle once for each cutting, thereby generating an analog signal, and then the axle counting host unit 20 determines whether the state of the detection section is an idle state or an occupied state based on the analog signal.

[0049] Figure 3 In the equation, angle θ is the angle between the magnetic induction intensity and the vertical plane of the receiving coil. When the cross-sectional area of ​​the coil S and the vertical plane of the magnetic induction intensity B have an angle θ, the magnetic flux Φ = B·S·cosθ (Formula 1). When the axle counter sensing plate 13 enters the alternating magnetic field, since the magnetic permeability of the metal is much greater than the magnetic permeability of the air, the magnetic lines of force move downward, the angle θ increases, and according to Formula 1, the magnetic flux Φ decreases. The formula for calculating the induced electromotive force is E = nΔΦ / Δt. If n and t remain unchanged and Φ decreases, the induced electromotive force E decreases, that is, the induced voltage of the receiving coil decreases. The analog signal is generated by the change law of the induced voltage amplitude to achieve the purpose of wheel detection.

[0050] Compared with the existing technology, the precise counting of the number of vehicle axles can be achieved through the interaction between the axle counter sensing plate 13 and the axle counter sensor, as well as the adjustment of the processing module.

[0051] Optimize the above technical solutions, such as Figure 1 and Figure 2As shown, when the Yunba passes the axle counter sensor 10, the projection of the axle counter sensor 10 in the horizontal direction of the track beam 11 is located within the projection of the axle counter sensing plate 13 in the horizontal direction of the track beam 11. This arrangement prevents the rubber wheel from shaking during the driving of the vehicle, and the axle counter sensing plate 13 may not pass the sensor correctly, thereby causing the system to have an "axle loss" fault. Figure 2 As shown, the detection distance L between the axle counter sensor 10 and the axle counter sensor plate 13, and the installation coverage height H of the axle counter sensor 10 (that is, the size of the axle counter sensor plate 13 higher than the axle counter sensor 10) should be noted that in actual application, the detection distance L and the coverage height H can be selected according to actual needs.

[0052] Optimize the above technical solutions, such as Figure 3 As shown, the axle counter sensor 10 includes: a first receiving coil 14, a transmitting coil 15 and a second receiving coil 16 which are arranged in sequence along the longitudinal direction of the track beam 11. It should be noted that the magnetic flux lines 17 of the first receiving coil 14 form a first detection signal, and the magnetic flux lines 17 of the second receiving coil 16 form a second detection signal. When the cloud bus passes by, the axle counter induction plate 13 cuts the magnetic flux lines 17 of the first receiving coil 14 and the second receiving coil 16 in sequence (or cuts the magnetic flux lines 17 of the second receiving coil 16 and the first receiving coil 14 in sequence); it should also be noted that the direction of the train can be determined according to the order in which the first detection signal and the second detection signal are cut.

[0053] Optimize the above technical solutions, such as Figure 1 As shown, the axle counter induction plate 13 is vertically installed on the lower end surface of the guide wheel 12. Such an arrangement makes it easier for the axle counter induction plate 13 to cut the magnetic flux lines emitted by the axle counter sensor 10, thereby improving the detection accuracy.

[0054] In this technical solution, if Figure 5 As shown, the axle counting host unit 21 includes: a signal processing module 212 and a counting module 213, the counting module 213 has the function of displaying the axle number information and working status, and outputting alarm information for self-diagnosis;

[0055] The signal processing module 212 pre-processes the analog signal generated by the axle counter sensor 10 to convert it into an analog level signal;

[0056] The counting module 213 receives the analog level signal, determines whether the state of the detection section is an idle state or an occupied state based on the analog level signal, and sends the determination of whether the state of the detection section is an idle state or an occupied state to the processing module.

[0057] In the above technical solution, the signal processing module is used to evaluate and process the signal of the outdoor axle counter sensor 10, provide a recognizable level signal to the counting module and transmit it to the counting module through the optical coupler output multiplexing interface. The signal processing module also has the function of supplying power to the axle counter sensor 10, has self-monitoring capability and can output monitoring information, and has the function of analog output counting module recognizable level. Each axle counter sensor 10 corresponds to a signal processing module. The counting module is the operation unit of the system, using the same hardware structure and software structure, using 2-out-of-2 cross comparison, and serial output; the software adopts a "back-to-back" design scheme to ensure the safety, accuracy and reliability of its output. The main function of the counting module is to receive the analog level signal processed by the signal processing module in the detection section, and based on the analog level signal, determine whether the detected section is occupied by a train; in addition, the counting module can also receive the axle detection information multiplexed by the signal processing board or other section signal processing board; it should also be noted that the counting module 23 includes an axle counter host, and the state of the detection section is determined to be idle or occupied by the axle counter host based on the analog level signal.

[0058] In one technical solution, Figure 5 As shown, it includes: a monitoring system 50, a counting module 213 transmits the status of the detection section as idle or occupied to the monitoring system, the counting module 213 includes an axle counting host unit, and the axle counting host unit transmits the monitoring information such as the section status to the monitoring system 50 via RS422 or Ethernet, thereby enabling the monitoring system 50 to dynamically monitor in real time, record data and perform statistical analysis.

[0059] In another technical solution, Figure 5 and Figure 6 As shown, the axle counter host unit 21 also includes: a voltage protection module 211, which is connected between the axle counter sensor 10 and the signal processing module 212. In the technical solution, the voltage protection module 212 is located inside the axle counter host cabinet, between the axle counter sensor 10 and the signal processing module 212. The voltage protection module 212 is used to prevent overvoltage from affecting the sensor and the signal processing module. Each axle counter sensor 10 corresponds to a voltage protection module 212.

[0060] The first embodiment of the relay mode, such as Figure 5 As shown, the processing module includes a relay module 30 and an interlocking system 40;

[0061] The relay module 30 includes: a track relay 31;

[0062] The counting module 213, the track relay 31 and the interlocking system 40 are connected in sequence; the counting module 213 transmits the idle or occupied state information of the detection section to the track relay 31. If the information received by the track relay 31 is the idle state, the track relay is attracted; if the information received is the occupied state, the track relay falls. The interlocking system 40 collects the contact state of the track relay 31 to obtain the idle state or occupied state of the detection section. In the above technical scheme, it can be judged whether the cloud bus passes through the detection section according to the action state of the relay 31. After obtaining the idle state or occupied state of the detection section, the interlocking system 40 provides a precondition for the lower computer of the interlocking system 40 to perform logical operations.

[0063] The second embodiment of the relay mode, such as Figure 4 and Figure 5 As shown, the processing module includes a relay module 30;

[0064] The relay module 30 includes: a reset relay 32;

[0065] The zeroing relay 32 is connected to the counting module 213. The zeroing relay 32 receives and executes the zeroing instruction. The counting module 213 collects the contact state of the zeroing relay 32 and changes the occupied state of the detection section to the idle state. In the above technical scheme, the setting of the zeroing relay 32 prevents certain interference, the first power-on or restart of the system, etc., which causes the detection section to change from a car-free state to an occupied state. The counting module 213 collects the information of the zeroing relay 32 executing the zeroing instruction, and changes the occupied state of the detection section to the idle state according to the execution result. It should be noted that the zeroing instruction includes: a pre-zeroing command and an immediate zeroing command; in one possible embodiment, the zeroing relay 32 includes a zeroing disk 321, and the pre-zeroing or immediate zeroing is manually pressed on the zeroing disk 321; in one possible embodiment, the counting module 213 also collects other conditional collection information on the zeroing relay 32.

[0066] A first embodiment of the communication mode, Figure 4 and Figure 6 As shown, the processing module includes: a communication module 60 and an interlocking system 40;

[0067] The counting module 213 , the communication module 60 and the interlocking system 40 are connected in sequence; the counting module 213 transmits the information that the state of the detection section is an idle state or an occupied state to the interlocking system 40 through the communication module 60 .

[0068] In the above technical solution, the idle or occupied state information of the detection section is directly transmitted to the interlocking system 40 through the communication module 60, so that the detection speed is greatly improved, and the inaccuracy of the axle counting system caused by the failure of the track relay 31 is avoided; as a preferred embodiment, the interlocking system transmits information such as the execution status of the interlocking system to the monitoring system 50, such as Figure 5 shown.

[0069] A second embodiment of the communication mode, Figure 4 and Figure 6 As shown, the processing module includes: a communication module 60 and an interlocking system 40;

[0070] The interlocking system 40, the communication module 60 and the counting module 213 are connected in sequence; the interlocking system 40 will receive the reset instruction and pass it to the counting module 213 through the communication module 60, and the counting module 213 will change the occupied state of the detection section to the idle state to prevent certain interference, the first power-on or restart of the system, etc., which will cause the detection section to change from a car-free state to an occupied state; it should be noted that the reset instruction of the interlocking system 40 can be input manually or by input from other technical modules; in one embodiment, the communication module 60, a communication host unit can be configured with up to 50 sections to communicate with the interlocking, and the communication interface adopts an Ethernet interface, the physical layer interface is RJ45, and the transport layer protocol is UDP.

[0071] In this technical solution, if Figure 8 As shown, the indoor module 20 further includes: a lightning protection distribution cabinet 22;

[0072] The input end of the lightning protection branch cabinet 22 is connected to the axle counter sensor 10, and the output end of the lightning protection branch cabinet 22 is connected to the axle counter host unit 21. In this technical solution, the setting of the lightning protection branch cabinet 21 improves the lightning protection capability of the entire line and enhances the electromagnetic interference protection capability.
