Wireless communication device with multiple interfaces

Abstract

The invention relates to a wireless communication device with multiple interfaces. A two-core +5V power binding post J1, a nine-core RS232 serial-port terminal DB1, a two-core RS485 interface terminal J2, a standard USB interface terminal J3 and a four-core CAN bus interface terminal J4 are arranged in a machine shell of the wireless communication device. Corresponding holes or corresponding installation holes are formed in the side face of the machine shell, wherein the two-core +5V power binding post J1, the nine-core RS232 serial-port terminal DB1, the two-core RS485 interface terminal J2, the standard USB interface terminal J3 and the four-core CAN bus interface terminal J4 extend out of the holes or installation holes. Holes where a three-digit horizontally-shifting dip switch is exposed are formed in the machine shell. Holes where light-emitting diodes RUN, TXD and RXD are exposed are formed in the machine shell. A round hole where an antenna extends out is formed in the other side face. A wireless transmitting and receiving circuit, a power source circuit, an information storage circuit, a work state indication circuit, a device addressing circuit, an RS232 interface circuit, an RS485 interface circuit, a USB interface circuit and a CAN bus interface circuit are arranged in the machine shell. The wireless communication device with the multiple interfaces is compact in structure, capable of effectively avoiding self-transmitting and self-receiving and achieving point-to-point communication and point-to-multiple-point communication between a computer and the device, multiple in selectable interface, capable of meeting more use requirements, convenient to install and use, and reliable in communication.
