Problems solved by technology
[0004] For above-mentioned technical problem, the purpose of the present invention is to overcome in the prior art, the CAN training equipment that the school uses basically all is a single operation, each CAN training equipment needs to be equipped with a CAN analyzer to test, not only Inconvenient to manage, and the problem of high cost, so as to provide a USB-to-CAN analyzer, and realize the signal acquisition and data communication of each training device through the additional controller. The teacher can perform multiple CAN By switching the bus of the training equipment, you can observe the data uploaded by each training equipment, and you can also grasp the operation of the students on the training equipment. The device that can realize the test of multiple CAN training equipment

The invention discloses a device capable of testing multiple CAN training devices. The device comprises a main controller, a CAN analyzer, a background server and a dial switch. The multiple CAN training devices are connected to the main controller through CAN buses, and the main control device, the CAN analyzer and the background server are connected in order. The main controller is also providedwith the dial switch, and the dial switch is used for controlling the disconnection and connection of channels between the main controller and the CAN training devices. The main controller is used for processing the CAN buses in the multiple CAN training devices and then outputting a path of CAN bus to the CAN analyzer. The CAN analyzer is used for carrying out signal acquisition and data communication on the connected CAN training devices, and collected signals and data are transmitted to the background server for storage and analysis. According to the device, the problem that each CAN training device needs to be equipped with a CAN analyzer for testing, the management is inconvenient, and the cost is high in the prior art are overcome.
Description
Technical field [0001] The invention relates to the field of CAN training equipment control, in particular to a device that can realize the test of multiple CAN training equipment. Background technique [0002] At present, the CAN training equipment used by the school basically runs on a single unit. When the data of the equipment needs to be uploaded to the computer for display or program download and debugging of the CAN (controller area network) bus equipment, professional CAN analysis is required. Nowadays, most of the analyzers using USB to CAN are generally used. This kind of analyzer is usually more expensive, especially the imported USB to CAN analyzer is more expensive. If each training device is equipped with a CAN analyzer and computer, it is practical The overall price of training equipment is very high, which is a high expenditure for schools or enterprises. [0003] Therefore, a USB-to-CAN analyzer is used to realize the signal acquisition and data communication of e...
