Abstract
The utility model discloses a device for monitoring CAN (controller area network) bus communication data, which comprises a CAN interface, a CAN driving unit, an MCU (microcontroller unit) and a serial port driving unit, wherein the CAN interface is used for connecting a CAN bus and downloading the data from the CAN bus to the CAN driving unit connected with the CAN interface; the CAN driving unit processes the data on the CAN bus and then transmits to the MCU connected with the CAN driving unit; the data is transmitted to an upper computer through the serial port driving unit and RS (recommend standard) 232/422 after the data is processed by the MCU; and a PC (personal computer) is connected with the serial port through a serial port line. When the communication baud rate of CAN is set by opening a hyper terminal, the communication data and identifiers among the devices can be displayed in the hyper terminal, so that the researcher and maintainer can conveniently find out problems among the devices. Besides, the device for monitoring the CAN bus communication data has the characteristics of simple structure, convenient production, low cost and the like, therefore, the device for monitoring the CAN bus communication data has wide application scope.
Description
Technical field
The utility model relates to a kind of device of the CAN of supervising bus communication data.
Background technology
In the broadcasting and TV field, the control of matrix becomes increasingly complex, CAN bus high performance price ratio, realize that outstanding advantage such as simple more and more obtains research staff's favor (as shown in Figure 1), but, rely on oscillograph to check that the communication data content has increased very big difficulty because the communication complexity between its bus is far longer than traditional RS232.Therefore designed a kind of method that supervises bus data easily.
Summary of the invention
The utility model is at the proposition of above problem, and develops a kind of device of the CAN of supervising bus communication data.The technological means that the utility model adopts is as follows:
A kind of device that supervises CAN bus communication data is characterized in that comprising: CAN interface, CAN driver element, MCU and serial port driving unit; Described CAN interface is used to connect the CAN bus, data on the CAN bus are downloaded in the CAN driver element that is connected with the CAN interface, described CAN driver element is transferred to among its MCU that is connected after with the data processing on the CAN bus, after MCU handles data is transferred in the host computer by serial port driving unit and RS232/422 again.
In comprising that also described CAN interface is connected by the CAN bus with the CAN interface on the equipment with CAN interface and the CAN interface that connects, described CAN interface is connected by the CAN bus with the CAN interface of next equipment that described equipment need connect.
With prior art compare the utility model has the advantages that conspicuous, PC is connected to serial ports by Serial Port Line, open hyper terminal and set the communication baud rate of CAN, the communication data of equipment room and identifier then are presented in the hyper terminal, greatly facilitate research staff and maintainer's searching the equipment room problem.Characteristics such as in addition, the utility model also has simple in structure, is convenient to produce, and is with low cost are suitable for extensive popularization.
Description of drawings
The structural representation that Fig. 1 is connected by the CAN bus for existing control panel and matrix;
Fig. 2 is a structured flowchart of the present utility model;
Fig. 3 is a device application implementation synoptic diagram described in the utility model.
Among the figure: 1, CAN interface, 2, the CAN driver element, 3, MCU, 4, serial port driving unit, 5, host computer, 6, the CAN interface.
Embodiment
A kind of as shown in Figure 2 device of the CAN of supervising bus communication data comprises: CAN interface 1, CAN driver element 2, MCU3 and serial port driving unit 4; Described CAN interface 1 is used to connect the CAN bus, data on the CAN bus are downloaded in the CAN driver element 2 that is connected with CAN interface 1, described CAN driver element 2 is transferred to among its MCU that is connected 3 after with the data processing on the CAN bus, after MCU 3 handles data is transferred in the host computer 5 by serial port driving unit 4 and RS232/422 again.Comprise that also described CAN interface 1 is connected by the CAN bus with the CAN interface on the equipment with CAN interface 1 and the CAN interface 6 that connects, described CAN interface 6 is connected by the CAN bus with the CAN interface of next equipment that described equipment need connect.At first set the speed of CAN bus communication by PC, in the CAN bus interface incoming interface of equipment room, the hyper terminal of opening PC can be checked the data and the identifier of bus.One in two CAN interfaces is input, one is output, if mainly be to consider that equipment room does not have unnecessary interface, then equipment wherein and connection insert input end, another connection is inserted output terminal, like this then do not influence the normal communication (as shown in Figure 3) of equipment.If equipment room has unnecessary interface, then this equipment is connected to input end and gets final product.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
