Abstract
The utility model discloses a device for monitoring RS485 bus communication data. The device comprises an RS485 interface, an RS485 driving unit, an MCU and a serial port driving unit. The RS485 interface is used for connecting an RS485 bus and downloading data on the RS485 bus into the RS485 driving unit, wherein the RS485 driving unit is connected with the RS485 interface. The data on the RS485 bus are processed by the RS485 driving unit, transmitted to the MCU which is connected with the RS485 driving unit, processed again by the MCU, and then transmitted to a host computer by the serial port driving unit and an RS22/422. Compared with the prior art, the advantages of the device is obviously. A PC is connected with a serial port by a serial port line, a hyper terminal is opened to set an RS485 communication baud rate, and communication data and identifiers among equipment are shown in the hyper terminal, thereby greatly facilitating research and development personnel and maintenance personnel to find problems among equipment. Besides, the device has characteristics of simple structure, convenient production, low cost, etc., and is suitable for a wide popularization.
Description
Technical field
The utility model relates to a kind of device of the RS485 of supervising bus communication data.
Background technology
In the broadcasting and TV field; The control of matrix becomes increasingly complex; RS485 bus high performance price ratio, realize that increasing acquisitions of outstanding advantage research staff such as simple favors; But, rely on oscilloscope 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 device that supervises bus data easily.
Summary of the invention
The utility model is directed against the proposition of above problem, and develops a kind of device of the RS485 of supervising bus communication data.The technological means that the utility model adopts is following:
A kind of device that supervises RS485 bus communication data; It is characterized in that comprising: the RS485 driver element; MCU, serial port driving unit be used to be connected the RS485 bus, the data on the RS485 bus are downloaded to the RS485 interface in the RS485 driver element that is connected with the RS485 interface; Said RS485 driver element is transferred to among its MCU that is connected after with the data processing on the RS485 bus, again after MCU handles with data through serial port driving unit through the RS232/422 bus transfer in host computer.
Comprise that also said RS485 interface is connected through the RS485 bus with the RS485 interface on the equipment with RS485 interface and the RS485 interface that connects, said RS485 interface is connected through the RS485 bus with the RS485 interface of next equipment that said equipment need connect.
With prior art compare the utility model has the advantages that conspicuous; PC is connected to serial ports through Serial Port Line; Open hyper terminal and set the communication baud rate of RS485; Communication data that equipment is asked and identifier then are presented in the hyper terminal, greatly facilitate research staff and attendant and search what equipment was asked questions.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
Fig. 1 is the structured flowchart of the utility model.
Among the figure: 1.RS485 interface I, 2.RS485 driver element, 3.MCU, 4. serial port driving unit, 5. host computer, 6.RS485 interface II.
Embodiment
The device of a kind of RS485 of supervising bus communication data as shown in Figure 2 comprises: RS485 interface 1, RS485 driver element 2, MCU3 and serial port driving unit 4; Said RS485 interface 1 is used to connect the RS485 bus; Data on the RS485 bus are downloaded in the RS485 driver element 2 that is connected with RS485 interface 1; Said RS485 driver element 2 is total with RS485, be transferred to among its MCU that is connected 3 after the data processing on the line, after MCU 3 handles, data is transferred in the host computer 5 with RS232/422 through serial port driving unit 4 again.Also comprise with RS485 interface 1 and the RS485 interface 6 that connects; Said RS485 interface 1 is total through RS485 with the RS485 interface on the equipment, line is connected, and said RS485 interface 6 is connected through the RS485 bus with the RS485 interface of next equipment that said equipment need connect.At first set the speed of RS485 bus communication through PC, in the RS485 bus interface incoming interface of equipment room, the hyper terminal of opening PC can check that the data of bus and sign spread out.One in two RS485 interfaces is input; One mainly is that consideration equipment is asked if there is not unnecessary interface for output, then inserts input to the beautiful connection of equipment wherein; Insert output to another connection, like this then do not influence the normal communication (as shown in Figure 3) of equipment.If equipment room has unnecessary interface, then be connected to input to this equipment and get final product.
The above; Be merely the preferable embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or changes according to the technical scheme of the utility model and inventive concept thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection range of the utility model.
