Abstract
The utility model relates to an interface conversion device of data transmission device, in particular to a wireless transmission RS232 and RS485 interface conversion device, which comprises a RS232 interface controller which is connected with a RS232 interface bus and a RS485 interface controller which is connected with the RS485 interface bus, wherein the RS232 interface controller is connectedwith a first antenna through a first wireless interface, and the RS485 interface controller is connected with a second antenna through a second wireless interface. The wireless transmission RS232 andRS485 interface conversion device can achieve the mutual conversion of RS232 and RS485 interface signals under the condition without long-distance wiring, and has convenient implementation and high reliability.
Description
Technical field
The utility model relates to a kind of interface switching device of data transmission device, specifically is a kind of RS232 and RS485 interface switching device of wireless transmission.
Background technology
At present, the RS232 interface commonly used and the conversion equipment of RS485 interface all adopt wired mode, have distance owing to have the RS232 interface between the two with the equipment that has the RS485 interface, also need connect up after interface conversion again, change mutually to reach interface, realize the purpose of data communication.In many application scenarios, because the restriction of environment for use, wall punching need be opened, perhaps, wiring need be changed repeatedly in the frequent occasion of exchange device more, cause wiring in disorder, easy wrong line, and if wiring be on ground, places such as passageway, often take place because of the situation of trampling, towing or damaged by rats break, thereby cause Communications failure.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, implement convenient, need not to connect up, the RS232 and the RS485 interface switching device of wireless transmission that dependability is high.
Interface switching device of the present utility model includes a RS232 interface controller that is connected with the RS232 interface bus and a RS485 interface controller that is connected with the RS485 interface bus, described RS232 interface controller is connected with first antenna through first wave point, and described RS485 interface controller is connected with second antenna through second wave point.The RS485 interface controller can be converted to the RS485 interface signal wireless signal and maybe the wireless signal that receives is converted to the RS485 interface signal; And the RS232 interface controller can be converted to the RS232 interface signal wireless signal or wireless signal is converted to the RS232 interface signal.
The utility model can be realized the mutual conversion of RS232 and RS485 interface signal under the condition that need not long distance wiring, enforcement is convenient, reliability is high.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
