Abstract

The invention provides a hand-held CAN bus data analysis device comprising a processor, a CAN bus interface module, a power supply management module and a storage battery, wherein the processor is connected with the CAN bus interface module and the power supply management module; and the storage battery is connected with the power supply management module. The device collects signals from an external CAN bus through the CAN bus interface module and processes the signals in the processor, so that CAN bus communication can be carried out; the storage battery can provide power for the whole hand-held CAN bus data analysis device without an external power source, without being limited to the usage of a DC power source on a railway vehicle, and facilitating field debugging; and through the utilization of the power supply management module, voltage conversion and control can be performed on the voltage output by the storage battery, thereby meeting the need of the processor as well as the needs of other function modules connected with the processor. Besides, the device in the invention is a hand-held device; and the device is small in size and convenient to carry.

Description

technical field [0001] The invention relates to rail transit technology, in particular to a hand-held CAN bus data analysis device. Background technique [0002] With the rapid development of rail transit technology, vehicle bus is more and more widely used in vehicles. CAN bus is more and more favored by rail manufacturers because of its advantages such as simple networking, low cost, and high reliability. In its application, the data analysis device based on CAN bus is an indispensable device in the process of vehicle network debugging. [0003] Currently, the CAN bus data analysis device uses the following two devices: a general-purpose oscilloscope and a CAN bus analyzer. General-purpose oscilloscopes are mainly some mainstream oscilloscopes on the market. The disadvantages of this type of equipment are that they are bulky, have many functions unrelated to the CAN bus, and complex operations. They need to have the relevant background knowledge of professional hardware c...
