[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0038] The embodiment of the present invention provides a modular vehicle, which can solve the technical problem that the existing modular vehicle relies on manual dialing to determine the number of each axis vehicle and the number of axis vehicles, which is time-consuming and labor-intensive.

[0039] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a modular vehicle, which includes: a power locomotive 1 and multiple axis vehicles 2.

[0040] The power locomotive 1 is provided with a power supply 11 and a controller 12, and each axis vehicle 2 is provided with a connected sampling resistor 21 and a sampling unit 22. When multiple axis vehicles 2 are connected to the power locomotive 1, the sampling resistors 21 of the multiple axis vehicles 2 are connected to the power supply 11, and the sampling units 22 of the multiple axis vehicles 2 are connected to the controller 12, and the controller 12 is configured as follows:

[0041] Acquire the electrical signals collected by the sampling units 22 of all axis vehicles 2;

[0042] The serial number of each axle vehicle 2 and the actual total number of axle vehicles 2 are determined based on the electrical signals collected by all sampling units 22 .

[0043] Specifically, see Figure 2 As shown, the sampling resistors 21 of multiple axis vehicles 2 are connected in parallel to the power supply 11, and the sampling unit 22 of each axis vehicle 2 is used to collect the total current of the sampling resistor 21 of the corresponding axis vehicle 2 and the sampling resistors 21 of all the subsequent axis vehicles 2 in parallel. The sampling unit 22 is a current sensor, which can be a Hall current sensor.

[0044] Figure 2There are three axis cars 2 in the figure. The power locomotive 1 provides power 11. The resistance of the sampling resistor 21 of each axis car 2 is the same. According to the principle of series and parallel connection of circuits, when the resistors are connected in parallel, the voltage of each resistor is the same, and the sum of the branch currents is equal to the main circuit current. Then: the current of the first axis car 2 is equal to the voltage of the power supply 11 divided by one-third of the resistance of the sampling resistor 21; the current of the second axis car 2 is equal to the voltage of the power supply 11 divided by one-half of the resistance of the sampling resistor 21; the current of the third axis car 2 is equal to the voltage of the power supply 11 divided by the resistance of the sampling resistor 21. At the beginning of the design of the module car, the number of axis cars 2 of this module car will be determined. If the number of groups exceeds the design, the power will be insufficient and unable to operate. According to the number of groups designed, the appropriate resistance value and power supply voltage can be calculated to determine the number position of the axis car 2.

[0045] For example, suppose the number of axis cars 2 is designed to be 5, and the current monitoring range of the controller 12 is 0-20mA. Under normal circumstances, the DC power supply is DC24V, R=U / I. It can be seen that the resistance of the whole vehicle must be greater than 24V / 0.02A=1200Ω, so as not to exceed 20mA. The number of axis cars 2 is 5, and the resistance of the sampling resistor 21 of each axis car 2 is the same. Then the resistance of the sampling resistor 21 of a single axis car 2 is 1200*5=6000Ω. When a single axis car 2 is connected to the power locomotive 1, the current is 4mA, so the maximum and minimum are both within the range of 0-20mA, which meets the current monitoring range of the controller. Further calculations show that:

[0046] The current of the first axis car = 24 / (6000 / 5) = 20mA;

[0047] The current of the second axis car = 24 / (6000 / 4) = 16mA;

[0048] The current of the third axis car = 24 / (6000 / 3) = 12mA;

[0049] The current of the fourth axis car = 24 / (6000 / 2) = 8mA;

[0050] The current of the fifth axis car = 24 / (6000 / 1) = 4mA;

[0051] Different axis vehicles 2 feed back the current values ​​collected by their sampling units 22 to the controller 12, and the controller 12 identifies the order of the axis vehicles 2 themselves based on the current values. For example, if the collected current is 20mA, it is the first axis vehicle; if the measured current is 8mA, it is the fourth axis vehicle. Affected by the measurement accuracy, the position of the axis vehicle can also be determined according to the current range. For example, when the current is set in the range of 11-13mA, it can be judged as the third axis vehicle, which is more reliable. It should be noted that when only one axis vehicle 2 is connected to the power locomotive 1, the above method can also be used to number and count the actual number of axis vehicles 2.

[0052] In addition, after determining the serial number of each axle vehicle 2 and the actual total number of axle vehicles 2 according to the electrical signals collected by all sampling units 22, the method further includes:

[0053] Compare the actual total number of axle cars 2 with the preset number of marshaling;

[0054] If the actual total number of axle cars 2 is less than the preset number of formations, it is determined that an axle car off-line failure exists.

[0055] Specifically, the controller 12 determines the actual total number of the axle cars 2 according to the number of feedback currents, and then compares the actual total number of the axle cars 2 with the preset number of groups; if the actual total number of the axle cars 2 is less than the preset number of groups, it is determined that there is an axle car disconnection fault. This can avoid errors in the number of statistics, and thus avoid errors in the calculation of the angle setting of the power locomotive 1.

[0056] The modular vehicle in the embodiment of the present invention includes a power vehicle head and multiple axis vehicles, each of which is provided with a connected sampling resistor and a sampling unit. When multiple axis vehicles are connected to the power vehicle, the sampling resistor is connected to the power supply, and the sampling unit is connected to the controller. The controller can determine the number of each axis vehicle and the actual total number of axis vehicles according to the electrical signals collected by all sampling units. That is, the present invention can automatically identify the current number of each axis vehicle and the number of axis vehicles, saving time and labor, with a high degree of intelligence, reducing manual operation time, and improving work efficiency.

[0057] As an optional implementation, in an embodiment of the invention, see Figure 3 As shown, the sampling resistors 21 of multiple axis vehicles 2 are connected in series and connected to the power supply 11, and the sampling unit 22 of each axis vehicle 2 is used to collect the total voltage of the sampling resistor 21 of the corresponding axis vehicle 2 and the sampling resistors 21 of all the subsequent axis vehicles 2 in series. The sampling unit 22 is a voltage sensor.

[0058] The power locomotive 1 provides a power source 11, and the resistance value of the sampling resistor 21 of each axis car 2 is the same. According to the circuit series-parallel principle, when the resistors are connected in series, the current of each resistor is the same. The sampling unit 22 of the first axis car 2 collects the largest voltage, and the sampling unit 22 of the last axis car 2 collects the smallest voltage. Different axis cars 2 feed back the voltage values ​​collected by their sampling units 22 to the controller 12, and the controller 12 identifies the order of the axis cars 2 themselves according to the voltage values.

[0059] As an optional implementation, in an embodiment of the invention, see Figure 4 As shown, each axis car 2 is provided with a head bolt loosening detection assembly 23 and a tail bolt loosening detection assembly 24 connected to the controller 12. The head bolt loosening detection assembly 23 of each axis car is used to detect the connection status of the bolt 3 connection between the axis car 2 and the front power car head 1 or the axis car 2, and the tail bolt loosening detection assembly 24 of each axis car 2 is used to detect the connection status of the bolt 3 connection between the axis car 2 and the rear axis car 2.

[0060] The controller 12 is used to determine the actual total number of the axis vehicles 2 according to the feedback electrical signals of all the head bolt loosening detection components 23 and the tail bolt loosening detection components 24. Among them, the head bolt loosening detection components 23 and the tail bolt loosening detection components 24 are both metal proximity switch sensors.

[0061] The arrangement positions of the head bolt loosening detection assembly 23 and the tail bolt loosening detection assembly 24 are as follows: Figure 4 As shown, the metal proximity switch is arranged. The power locomotive head 1 and the axis locomotive 2, and the axis locomotive 2 and the axis locomotive 2 are connected and fixed by bolts 3. The head bolt loosening detection component 23 and the tail bolt loosening detection component 24 can use flush type metal proximity switch sensors, and detect in the detection direction shown by the arrow in the figure. The detection distance is selected to be greater than the distance from the nearest edge of the bolt and less than the farthest edge of the bolt, so that the metal proximity switch sensor can be triggered after the bolt is connected, and it will not be triggered by mistake when there is no bolt.

[0062] When the head bolt loosening detection component 23 and / or the tail bolt loosening detection component 24 of a single axle car 2 is triggered, an electrical signal (such as a level signal) is fed back to the controller 2 of the power locomotive 1. The controller 2 counts whether the axle car is connected normally based on the number of received signals. Taking the number of axle cars 2 as an example, the controller 2 can theoretically receive signals from 5 head bolt loosening detection components 23 and 4 tail bolt loosening detection components 24. Once the number of signals decreases, it can be determined that there is an axle car offline failure. In addition, the feedback electrical signal results of the head bolt loosening detection component 23 and the tail bolt loosening detection component 24 are combined with the electrical signal collected by the aforementioned sampling unit 22 to determine the online status of the axle car 2.

[0063] An embodiment of the present invention provides a method for using a modular vehicle, the method comprising the following steps:

[0064] Acquire the electrical signals collected by the sampling units 22 of all axis vehicles 2;

[0065] The serial number of each axle vehicle 2 and the actual total number of axle vehicles 2 are determined based on the electrical signals collected by all sampling units 22 .

[0066] As an optional implementation, in an embodiment of the invention, after the step of determining the serial number of each axle vehicle 2 and the actual total number of axle vehicles 2 according to the electrical signals collected by all sampling units 22, the method further includes:

[0067] Compare the actual total number of axle cars 2 with the preset number of marshaling;

[0068] If the actual total number of axle cars 2 is less than the preset number of formations, it is determined that an axle car 2 offline fault exists.
