Wherein CANBUS is a CAN BUS technology, and is fully called a controller area network BUS technology (controllerareaanetwork-BUS). Can-Bus technology was first used for communication of electronic systems for weapons such as airplanes and tanks. The technology used for civilian vehicles originated in europe at the earliest, and on-board such bus networks were used for the transfer of various sensor data on board. The intelligent high-voltage power distribution manager module exchanges information with the whole vehicle controller through the CANBUS, and the on-off control of the contact device is completed by receiving the instruction of the whole vehicle controller, so that the complexity of the wire harness between the whole vehicle controller and the high-voltage power distribution manager is greatly reduced.

The standard interface for RS232 Chinese name asynchronous transmission requires that both parties of communication adopt a standard interface during serial communication, so that different devices can be conveniently connected for communication. The RS-232-C interface (also known as EIARS-232-C) is one of the most commonly used serial communication interfaces. (-C in "RS-232-C" merely represents a version of RS-232 and is therefore the same for short as "RS-232").
Which was a standard for serial communications commonly established in 1970 by the united states Electronics Industry Association (EIA) with bell systems, modem manufacturers, and computer terminal manufacturers. Its full name is "serial binary data exchange interface technology standard between Data Terminal Equipment (DTE) and Data Communication Equipment (DCE)" which specifies that a 25-pin DB-25 connector is used, the signal content of each pin of the connector is specified, and the levels of the various signals are also specified. Later IBM's PC reduced RS232 to DB-9 connector, becoming a de facto standard. Whereas the RS-232 port of industrial control typically uses only RXD, TXD, GND wires.
It should be noted that in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
