Abstract

This application discloses a bus monitoring system. Multiple node devices are connected to the bus. Each node device includes a first power supply device and a transceiver device connected to the bus. The bus monitoring system includes a A monitoring device and a switching device, the switching device is arranged between the first power supply device and the transceiver device, wherein the monitoring device is used to detect whether the transceiver device is in an abnormal transmission state during the non-transmitting phase, if so, control the switching device to turn off, In order to power down the transceiver unit and no longer send data to the bus. The present application can control the power supply of the transceiver device. When the node equipment fails, the power of the transceiver device is controlled, so as to ensure that the transceiver device will not randomly send data to the bus, thereby avoiding the failure of the node equipment to occupy the bus for a long time. The occurrence of bus paralysis improves the reliability of bus communication.

Description

technical field [0001] The present application relates to the field of industrial control, in particular to a bus monitoring system. Background technique [0002] The 485 bus is a very common industrial bus. There are many devices attached to the bus. When any device attached to it fails, the faulty device may send data to the bus indiscriminately, occupying the bus, and causing the bus to be paralyzed. , which affects the data interaction of other devices on the bus and reduces the reliability of bus communication. At present, there is no solution that can prevent the bus from being paralyzed due to device failure. [0003] Therefore, how to provide a solution to the above technical problem is a problem that those skilled in the art need to solve at present. SUMMARY OF THE INVENTION [0004] The purpose of this application is to provide a bus monitoring system, which can control the power supply of the transceiver device, and control the power supply of the transceiver d...
