Abstract

The invention discloses a CAN bus remote transmission device and a transmission method thereof and belongs to the field of metering and monitoring. The device comprises a CAN bus, CAN monitoring intelligent nodes and direct current metering devices. The CAN bus is connected with the CAN monitoring intelligent nodes and the direct current metering devices. A plurality of CAN monitoring intelligentnodes and a plurality of direct current metering devices are set. Each CAN monitoring intelligent node comprises an MCU, a CAN controller, a CAN transceiver, a wireless communication module and a DC-DC power module. The MCU is in bidirectional connection with the wireless communication module. The MCU is connected with the CAN controller and the DC-DC power module. The CAN controller is in bidirectional connection with the CAN transceiver. The CAN transceiver is connected with the CAN bus. According to the device and the method, a great number of manpower and material resources are reduced, and data useful to workers in CAN messages can be rapidly monitored.

Description

technical field [0001] The invention belongs to the field of measurement monitoring, in particular to a CAN bus remote transmission device and a transmission method thereof. Background technique [0002] With the development of society and the continuous progress of human beings, life is becoming more and more convenient. Charging piles for electric vehicles can be seen everywhere. Battery status. However, due to the large amount of CAN message data, it takes a lot of manpower and material resources to monitor the data useful to the staff in the CAN message. Therefore, how to monitor in real time the data useful to the staff in the CAN message is an urgent matter. Contents of the invention [0003] The present invention overcomes the above-mentioned deficiencies in the prior art, and provides a CAN bus remote transmission device and a transmission method thereof, in which the CAN monitoring intelligent node is connected to the CAN bus, and the MCU analyzes and judges the...
