[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0049] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] like Figure 1 As shown, the present invention provides a positioning system for supply components of a rail vehicle, comprising a conveyor line 1, an information identification unit 3, an information recognition unit 4 and a control unit.

[0052] Specifically, the conveyor line 1 is used to convey the supply component 2, the information identification unit 3 is installed on the supply component 2, the information identification unit 3 has information corresponding to the supply component 2, the information identification unit 4 is provided in plurality, and is installed one by one at multiple preset positions of the conveyor line 1, the information identification unit 4 is used to read the information sent by the information identification unit 3, and the control unit obtains the position information of the supply component 2 on the conveyor line 1 according to the installation position of the information identification unit 4.

[0053] The above-mentioned positioning system is used to ensure that each supply component 2 equipped with an information identification unit 3 is transported on the conveyor line 1. During the transportation process, the information identification unit 4 set at multiple preset positions of the conveyor line 1 can read the information of the information identification unit 3 in real time, and send the information to the control unit, so as to position the supply component 2 during the transportation process and accurately obtain the real-time position of each supply component 2. If a supply component 2 stays at one position for a long time, it is convenient to find the supply component 2 through the position information of the supply component 2, so as to ensure that the subsequent assembly can proceed smoothly.

[0054] Furthermore, a plurality of preset positions of the conveyor line 1 are provided with support members, and the information identification unit 4 is installed on the support members. The support members include but are not limited to upright posts.

[0055] Preferably, a plurality of the information identification units 4 are arranged at equal intervals on at least one side of the conveyor line 1 along the conveying direction of the conveyor line 1 .

[0056] More preferably, a plurality of the information identification units 4 are arranged at equal intervals on both sides of the conveying line 1 along the conveying direction of the conveying line 1, ensuring that the plurality of the information identification units 4 are installed on the support at the preset position at a fixed distance. In addition, the identification area of ​​the information identification unit 4 is set as a fan-shaped area, ensuring that the information identification unit 4 can accurately identify the information identification unit 3 installed on the supply component 2 on the conveying line 1, and will not cause mutual interference to the surrounding information identification units 4.

[0057] In addition, the information identification unit 4 includes a fixed reader and a handheld reader. The fixed reader can be installed in a column, on a wall, on an I-beam, or on a platform. The handheld reader is used by the staff to read and write the information identification unit 3 when the fixed reader is offset.

[0058] Specifically, the columns include door columns outside the assembly process, independently established columns and table columns. A fixed reader is installed at the front end of the table, and the parameters of the fixed reader are set to read the range of the supply component 2, and the supply component 2 is read when it passes by.

[0059] Specifically, at the platform position in the factory, the platform installation method is selected, the fixed reader is installed at the connection between the column and the platform, the information identification unit 3 is installed on the vehicle body between 1.5 meters and 1.8 meters, and this platform position is too close to the body of the vehicle. You only need to adjust the height of the fixed reader so that the fixed reader faces the information identification unit 3.

[0060] Specifically, the track near the column inside the factory is installed by I-beam, and the fixed reader is installed by I-beam, and fixed to the column by bolt clamp, which can achieve non-destructive installation and can be changed at any time, which is convenient for disassembly and maintenance. The height of the fixed reader installation position is greater than 1800mm, which can effectively prevent collision and avoid personal injury.

[0061] Specifically, for one side of the workshop close to the wall, a fixed reader is installed on the wall by using the wall installation method to identify the information identification unit 3.

[0062] Furthermore, the working parameters of the fixed reader at least include working frequency, implementation standard and reading distance. The working frequency of the fixed reader is 920MHz to 925MHz, the implementation standard is EPC Global Class IGen 2 / ISO-18000-6C, and the reading distance of the fixed reader is 6 meters to 8 meters.

[0063] The working parameters of the handheld reader at least include working frequency, implementation standard, reading and writing function and protection level. The working frequency and implementation standard of the handheld reader are the same as those of the fixed reader. The reading and writing function of the handheld reader meets the UHF ultra-high frequency reading and writing function. The protection level of the handheld reader is higher than IP65.

[0064] Preferably, a plurality of the information identification units 3 are provided, and each of the information identification units 3 stores information adapted to the supply component 2 .

[0065] Preferably, one conveyor line 1 is provided, and the conveyor line is capable of conveying multiple types of supply components 2, that is, the same type and / or different types of supply components 2 are conveyed on one conveyor line 1 at the same time, and the position information of the supply components 2 is acquired in real time.

[0066] Alternatively, a plurality of conveyor lines 1 are provided, and the same conveyor line 1 conveys the same type of supply components 2. The purpose of doing so is to facilitate real-time monitoring of the position of the same type of supply components 2, and more importantly, to be able to adjust the overall layout of the conveyor line according to the shape, size and weight of the same type of supply components 2, for example, to reasonably set the width and transmission speed of the conveyor line 1, to ensure that the supply components 2 can move forward at the optimal path and speed during the conveying process, to avoid conveying obstacles caused by different characteristics of the supply components 2, thereby speeding up the conveying speed of the supply components 2 and increasing the conveying volume of the supply components 2 per unit time.

[0067] Preferably, the installation method of the information identification unit 3 is adapted to the type of the supply component 2 to ensure that the information identification unit 3 is installed at a relatively appropriate position on different types of supply components 2. For example, for a cylindrical supply component 2, a ring-shaped installation method can be adopted, and for a flat supply component 2, the supply component 2 can be installed on its surface to avoid interference with the information identification unit 3 due to its own structure.

[0068] More preferably, the information identification unit 3 is installed on the supply component 2 in different installation modes.

[0069] Specifically, the information identification unit 3 is installed on the supply component 2 in a direct or indirect installation manner. It can be understood that the installation manners of different types of supply components 2 can be the same or different.

[0070] It should be noted that the supply component 2 at least includes a wheelset, a bogie, and a car body. It can be understood that the wheelset, the bogie, and the car body are all common components of rail vehicles. The information identification unit 3 is directly installed on the wheelset and the bogie, and the information identification unit 3 is indirectly installed on the car body.

[0071] Furthermore, the direct installation method includes an adsorption or bonding installation method. It should be noted that the adsorption installation method includes but is not limited to magnetic attraction. Specifically, the material of the wheelset and the bogie includes but is not limited to at least one of carbon steel, alloy steel and cast steel, and has ferromagnetism. In addition, in order to facilitate the assembly of the information identification unit 3 on the wheelset or the bogie, the information identification unit 3 is installed on the surface of the wheelset or the bogie by magnetic attraction.

[0072] And / or, the indirect installation method includes clamping the information identification unit 3 on a mounting bracket provided on the vehicle body. Specifically, the vehicle body includes a vehicle body chassis, a vehicle body side wall, a vehicle body end wall and a vehicle roof. Since the structure of the vehicle body is relatively long and the vehicle body is provided with a mounting bracket, the information identification unit 3 is clamped on the mounting bracket of the vehicle body by clamping.

[0073] Furthermore, the working parameters of the information identification unit 3 include at least one of size, protection level, working frequency and reading distance.

[0074] Specifically, the size of the information identification unit 3 is about 150mm×50mm×12mm, the protection level of the information identification unit 3 is higher than IP67, the operating frequency of the information identification unit 3 is 905MHz~928MHz, and the reading distance of the information identification unit 3 is 6 meters to 8 meters.

[0075] In addition, the positioning system of the supply components of the rail vehicle also includes a trolley that carries the vehicle body. Usually, when the vehicle body is assembled on the trolley and transported through the corresponding conveyor line 1, an acrylic box is often assembled on the supporting column fixedly provided on the trolley, and the information identification unit 3 is placed in the acrylic box to obtain the position of the trolley.

[0076] In addition, for the structure after the bogie and the car body are installed, the position of the above structure is further obtained by assembling the information identification unit 3 in a sealed bag, fixing the sealed bag on the end wall of the car body, and conveying the structure after the bogie and the car body are installed on the corresponding conveyor line 1.

[0077] The positioning system for supply components of rail vehicles comprises an input unit for inputting information adapted to the supply component 2 into the information identification unit 3 .

[0078] Preferably, the input unit is arranged at the starting position of the conveyor line to input the information matching the supply component 2 into the information identification unit 3. Specifically, the information corresponding to each supply component 2 is input manually. It can be understood that the information corresponding to the supply component 2 at least includes the number information of each supply component 2, that is, different numbers represent different supply components 2 on the same conveyor line 1, and the position of the supply component 2 corresponding to the number can be determined further according to the different numbers.

[0079] Preferably, the basic position of the supply component 2 is obtained according to the time when the information recognition unit 4 triggers the recognition action and the speed of conveying the supply component 2;

[0080] Preferably, the speed of conveying the supply component 2 is the average speed of the conveying line 1. More preferably, the conveying line 1 conveys at a uniform speed.

[0081] It should be noted that the information identification unit 3 includes but is not limited to an RFID tag, and the information identification unit 4 includes but is not limited to an RFID reader. The RFID tag is detachably mounted on the supply component 2 to achieve binding of the RFID tag with the supply component 2. When the RFID tag receives a read signal from the RFID reader, the information stored in the RFID tag is sent to the RFID reader. It is understandable that the RFID tag can be a passive RFID tag or an active RFID tag.

[0082] In addition, the assembly system of the rail vehicle also includes RFID management software and a big data platform, the RFID management software is communicatively connected with the control unit and the big data platform, and the RFID management software can transmit the position information of each supply component 2 obtained by the control unit to the big data platform. Preferably, the big data platform can also be connected with the ERP system and the WMS system.

[0083] The RFID management software has the functions of visual display of rail vehicles, abnormal RFID reader processing, station management, historical track query of rail vehicles, and RFID tag management.

[0084] like Figures 2 to 3 As shown, the present invention also provides a positioning method for a supply component of a rail vehicle, the positioning method comprising:

[0085] The information identification unit 3 is installed on the supply component 2, and the information identification unit 4 is installed at a preset position of the conveying line 1;

[0086] Controlling the conveying line 1 to convey the supply component 2;

[0087] The control unit obtains the position of the information recognition unit 4 that triggers the recognition action, and determines the position of the supply component 2 according to the position.

[0088] By adopting the above-mentioned positioning method, the position of each of the supply components 2 is obtained in real time. If the supply component 2 stays at a certain position on the conveyor line 1 for a long time, it can be determined that the conveyor line 1 at this position may be blocked, and the speed of the conveyor line 1 can be adjusted in time or the staff can be notified to locate the supply component 2 at this position to deal with the above-mentioned blockage.

[0089] Specifically, controlling the conveying of the conveyor line 1 includes adjusting parameters such as the conveying speed, conveying direction, and conveying time of the conveyor line 1 to ensure that the supply component 2 can be safely and efficiently conveyed along a predetermined route.

[0090] Preferably, before the information identification unit 3 is installed on the supply component 2 , the method further includes entering information adapted to the supply component 2 into the information identification unit 3 .

[0091] Preferably, after the supply component 2 is transported by the conveyor line 1, the process further includes removing the information identification unit 3 installed on the supply component 2 for recycling.

[0092] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
