Title:
BUS PROCESSING APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/137593
Kind Code:
A1
Abstract:
A bus processing apparatus and system. The apparatus comprises: a first switch device, a second switch device, a power supply, a first resistor, and a second resistor. A control electrode of the first switch device is connected to a transmit end (i.e., TX1) of a first transceiver, a first electrode is connected to a receiving end (i.e., RX1) of the first transceiver, and a second electrode is connected to a transmit end (i.e., TX2) of a second transceiver and is connected to the power supply by means of the first resistor. A control electrode of the second switch device is connected to TX2, a first electrode is connected to a receiving end (i.e., RX2) of the second transceiver, and a second electrode is connected to TX1 and is connected to the power supply by means of the second resistor. The first switch device is used for: disconnecting a path between RX1 and TX2 when the level of TX1 is a low level. The second switch device is used for: disconnecting a path between RX2 and TX1 when the level of TX2 is a low level. Therefore, a self-locking phenomenon during CAN bus connection can be avoided.
