Problems solved by technology

For the learning and teaching of the HART bus protocol, the above common learning tools have the following defects and deficiencies: (1) The code and code meaning cannot be displayed intuitively, and it can only be compared by checking the manual and other tools and software, which is cumbersome
(2) Each manufacturer mainly communicates with its own products, and the versatility is not strong
(3) It must be connected to a HART instrument and cannot work alone, and the demonstration system is more complicated

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Such as figure 1 As shown, a HART bus protocol learning system includes HART bus protocol learning software installed on a PC computer, a HART protocol learning box, the input end of the HART protocol learning box is connected to the PC computer through the RS232 interface, and the output end is connected to the HART protocol instrument.

[0019] Such as figure 2 As shown, the HART bus protocol learning software displays the sent and received codes, analyzes and explains them, and displays the dialog box on the computer software interface through Chinese characters; the software process performs the following operations:

[0020] The first step is to turn on the computer PC and run the HART protocol learning software.

[0021] The second step is to configure the serial port and connect.

[0022] The third step is to select the command number to be communicated. ...

Abstract

The invention discloses an HART bus protocol learning system. The HART bus protocol learning system comprises HART bus protocol learning software installed in a PC and an HART protocol learning box; the input end of the HART protocol learning box is connected with the PC through an RS232 interface, and the output end of the HART protocol learning box is connected with an HART protocol instrument.The HART bus protocol software is installed on a working or household computer and is connected with the HART protocol learning box to form an HART bus protocol learning system. HART communication inan industrial field can be simulated, and the HART bus protocol learning can be connected with an HART instrument for communication testing. The HART bus protocol learning system can be used for testing the HART instrument and learning and experimenting the HART protocol.

Description

technical field [0001] The invention relates to a learning tool of the HART protocol, in particular to a learning system of the HART bus protocol. Background technique [0002] Currently commonly used learning tools for the HART protocol include HART communication adapters, serial port debugging assistants or instrument debugging software provided by various manufacturers. For the learning and teaching of the HART bus protocol, the above common learning tools have the following defects and deficiencies: (1) The code and code meaning cannot be displayed intuitively, and it can only be compared by checking the manual and other tools and software, which is cumbersome. (2) Each manufacturer mainly communicates with its own products, and the versatility is not strong. (3) The HART instrument must be connected and cannot work alone, and the demonstration system is more complicated. Contents of the invention [0003] In view of the problems existing in the prior art, the invent...
