Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementations of the present invention, and not all implementations, and all other embodiments obtained by those skilled in the art without any inventive work are included in the scope of the present invention.
As shown in fig. 1, an expansion communication C plug-in includes a BTM interface, a CPU, a serial controller, an internal first CAN controller, an internal second CAN controller, and an LKJ monitoring host, where the BTM interface is in communication connection with the CPU, and the CPU is in communication connection with the LKJI monitoring host through the internal first CAN controller and the internal second CAN controller, respectively.
The plug-in further comprises an LED indicator light which is electrically connected with the CPU.
The plug-in components also comprise an external first CAN controller, an external second CAN controller and external equipment, wherein the external equipment is in communication connection with the CPU through the external first CAN controller and the external second CAN controller.
The external device is not LAIS or GPS 2000.
In this embodiment, the BTM interface is communicatively coupled to the CPU via an external CAN controller.
The plug-in also comprises an RS232 controller and an ISP interface, and the ISP interface is electrically connected with the CPU through the RS 232. The ISP interface through RS232 may provide for program download to the CPU.
