[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] As Figure 1 shown, the present utility model discloses an information collection system serving the centralized maintenance of rail transit train components, including an RFID tag, a first RFID reader, a second RFID reader, a third RFID reader, a cloud server, and a smart terminal.

[0023] Specifically, the RFID tag is embedded in the centralized maintenance component, and the centralized maintenance component is a component of the rail transit train. The centralized maintenance component can be disassembled and placed in a transport truck or a component maintenance center. The first RFID reader is installed in the major overhaul base. When the rail transit train stops at the major overhaul base, the first RFID reader can identify the RFID tag on the rail transit train through short-range wireless communication. The second RFID reader is installed on the transport truck. When the transport truck loads the centralized maintenance component, it will identify the RFID tag of the loaded component. The third RFID reader is installed in the component maintenance center. When the component maintenance center temporarily stores the centralized maintenance component, it will identify the RFID tag in the component.

[0024] Further, the RFID tag located on the rail transit train is wirelessly communication-connected to the first RFID reader, and the first RFID reader is communication-connected to the cloud server. When the first RFID reader recognizes the RFID tag, it will forward the recognition information to the cloud server in real time. The RFID tag located on the transport truck is wirelessly communication-connected to the second RFID reader, and the second RFID reader is wirelessly communication-connected to the cloud server. When the second RFID reader recognizes the RFID tag, it will forward the recognition information to the cloud server in real time. The RFID tag located at the component maintenance center is wirelessly communication-connected to the third RFID reader, and the third RFID reader is communication-connected to the cloud server. When the third RFID reader recognizes the RFID tag, it will forward the recognition information to the cloud server in real time. The cloud server is used to aggregate the above recognition information and, based on the existing path planning algorithm, wirelessly forward the planning information to multiple intelligent terminals, so that the transport trucks holding the intelligent terminals can know the actual situation of the major overhaul base and the storage situation of the component maintenance center in real time, and thus timely transport the centralized maintenance components.

[0025] Compared with the prior art, the system of the present utility model has stronger real-time information acquisition ability, improves the transportation efficiency of the centralized maintenance components, and is conducive to minimizing the transportation cost of vehicle component centralized maintenance.

[0026] Further, an RFID tag is embedded in each centralized maintenance component, and each RFID tag has a unique ID. An ID reading unit and a location information forwarding unit are provided in each of the first RFID reader, the second RFID reader, and the third RFID reader. Each RFID reader can obtain the specific ID number of each centralized maintenance component through the ID reading unit, and bind the ID number with its specific location relationship through the location information forwarding unit, and uniformly forward the final binding information to the cloud server.

[0027] Further, the cloud server includes an information aggregation unit, a path planning unit, and a planning information forwarding unit communicatively connected to the path planning unit. The information aggregation unit is communicatively connected to the ID reading unit and the location information forwarding unit. The path planning unit is communicatively connected to the information aggregation unit, and the planning information forwarding unit is communicatively connected to multiple intelligent terminals. The information aggregation unit is used to aggregate the binding information sent by each RFID reader, and count the types and quantities of components to be repaired, the types and quantities of components already loaded on each transport truck, and the inventory in the component maintenance center. Through the above path planning unit combined with the above statistical data, based on the existing path optimization algorithms (such as: shortest path algorithm or ant colony algorithm), the optimal transfer path information of the transport truck is generated, and then the optimal transfer path information is sent to the corresponding transport truck through the planning information forwarding unit, thereby further improving the transportation efficiency of the centralized maintenance components.

[0028] Preferably, the present utility model further includes a GSM communication module. The first RFID reader, the second RFID reader, and the third RFID reader are respectively remotely communicatively connected to a cloud server through corresponding GSM communication modules. In addition, multiple above-mentioned intelligent terminals are also remotely communicatively connected to the cloud server through the above-mentioned GSM communication module.

[0029] Compared with the prior art, the system of the present utility model is internally provided with a GSM communication module, which is more suitable for long-distance wireless communication.

[0030] Preferably, the above RFID tag adopts a passive RFID tag. A passive RFID tag is an RFID tag that does not require a battery to be installed. The passive RFID tag is usually in a dormant state. Only when the RFID tag enters the recognition range of the corresponding RFID reader, it will be awakened based on the electromagnetic wave emitted by the RFID reader and send the ID information and location information to the corresponding RFID reader.

[0031] Through the above technical solution, the energy loss can be reduced and the service life of the RFID tag can be prolonged.

[0032] Preferably, the above intelligent terminal can be a smart phone or a tablet computer.

[0033] The working principle of the embodiment of the present utility model is as follows:

[0034] The centralized maintenance parts located on the rail transit train, transport truck, and component maintenance center will wirelessly communicate with the corresponding RFID reader through the RFID tags embedded in them. The corresponding RFID reader will forward the centralized maintenance part information to the cloud server in real time. After the cloud server performs path planning on the aggregated information, it will forward it to the corresponding intelligent terminal.

[0035] The above are all preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
