Description

A kind of general RS232 turns CAN switching control panels

Technical field

The utility model is related to a kind of switching control panel, more particularly to a kind of general RS232 to turn CAN switching control panels.

Background technology

Existing RS232 cannot realize the various numbers in the case of different baud rates from CAN during communication According to the information exchange of form, to using making troubles.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of general RS232 and turns CAN switching control panels, existing to solve There is the deficiency in technology.

In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions：

A kind of general RS232 is provided and turns CAN switching control panels, including single-chip microcomputer and connect the single-chip microcomputer respectively Light emitting diode group, CAN control chip, serial port level conversion core piece and mu balanced circuit, the single-chip microcomputer have UART mouthfuls, P0 mouthfuls and P3 mouthfuls, the serial port level conversion core piece is connected to UART mouthfuls of the single-chip microcomputer, and the CAN control chip connects P0 mouthfuls and P3 mouthfuls of the single-chip microcomputer is connect, wherein described P0 mouthfuls carries out data exchange, described P3 mouthfuls is written and read control, described steady Volt circuit includes 7805 three terminal regulators, and the single-chip microcomputer uses P89C52X2FN, the serial port level conversion core piece to use ICL232。

Above-mentioned general RS232 turns CAN switching control panels, wherein, the single-chip microcomputer is 8 single-chip microcomputers.

Above-mentioned general RS232 turns CAN switching control panels, wherein, also including automatic controller, the automatic controller connection The CAN control chip, the CAN control chip uses SJA1000, the automatic controller to use CTM050.

Compared with the prior art, the beneficial effects of the utility model are：

Realize RS232 to be in communication with each other with CAN, it is possible to achieve the letter of various data forms in the case of different baud rates Breath interaction, while the equipment of help original RS232 point-to-point structures realizes the function of multiple spot both-way communication.

Brief description of the drawings

The accompanying drawing for constituting a part of the present utility model is used for providing being further understood to of the present utility model, and this practicality is new The schematic description and description of type is used to explain the utility model, does not constitute to improper restriction of the present utility model. In accompanying drawing：

Fig. 1 to Fig. 4 respectively illustrates the separation structure schematic diagram that the general RS232 of the utility model turns CAN switching control panels.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can To be mutually combined.

Referring to figs. 1 to shown in Fig. 4, the general RS232 of the utility model turns CAN switching control panels includes single-chip microcomputer 1, Yi Jifen Not Lian Jie the light emitting diode group 2 of single-chip microcomputer 1, CAN control chip 3, serial port level conversion core piece 4 and mu balanced circuit 5, it is single Piece machine 1 has UART mouthfuls, P0 mouthfuls and P3 mouthfuls, and serial port level conversion core piece 4 is connected to UART mouthfuls of single-chip microcomputer 1, CAN control P0 mouthfuls and P3 mouthfuls of the connection single-chip microcomputer 1 of chip 3, wherein P0 mouthfuls carries out data exchange, and P3 mouthfuls is written and read control, mu balanced circuit 5 Including 7805 three terminal regulators, single-chip microcomputer 1 uses P89C52X2FN, serial port level conversion core piece 4 to use ICL232.In this case Single-chip microcomputer 1 is 8 single-chip microcomputers, and this control panel also includes automatic controller 6, the connection CAN control core of automatic controller 6 in addition Piece 3, automatic controller 6 uses CTM050, CAN control chip 3 to use SJA1000.

When the information of RS232 mouthfuls of reception, the useful data that receives or order can be packaged into CAN by single-chip microcomputer 1 Reference format hair to specific objective equipment, while when the information of CAN is received, after single-chip microcomputer 1 can also be unpacked, foundation The different-format of order and data is transmitted to the relevant device of serial ports connection.

From above-described embodiment as can be seen that advantage of the present utility model is：

Specific embodiment of the utility model has been described in detail above, but the utility model is not restricted to the above The specific embodiment of description, it is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all Among category of the present utility model.Therefore, the impartial conversion done in the case where spirit and scope of the present utility model are not departed from And modification, should all cover in the range of the utility model.
