Abstract
The invention discloses an automatic registering method of a serial communication terminal. In the field of serial communication, when the serial communication terminal is connected with an upper computer through a serial interface, the upper computer sends a handshaking request to all available serial interfaces according to available serial interface information prestored in a storage unit, if at least one serial interface feeds back a handshaking response, the upper computer is successfully handshaked and communicated with the serial communication terminal connected below the serial interface, and the serial interface information is deleted from the available serial interfaces stored in the storage unit. After the communication is established successfully, the serial communication terminal can send registering information cured in the serial communication terminal to the upper computer for registration, the upper computer stores the registering information of the serial communication terminal and information of the serial interface connected with the serial communication terminal into the storage unit of the upper computer, thus the serial communication terminal is automatically registered. The invention has the technical effects of greatly saving equipment debugging time and simplifying debugging program.
Description
Technical field
The present invention relates to communication technical field, particularly terminal device automatic registration method in the serial communication.
Background technology
At present, at instrument and meter and communication technical field, particularly use under the situations such as serial communication equipment is debugged, operation, usually need in equipment manager, check serial ports that computing machine has manual unlocking successively, causing the reduction and the insignificant duplication of labour of work efficiency, will be a no small workload if there are a lot of equipment to connect simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of serial communication terminal automatic registration method is provided, its step is as follows:
At first, in serial communication terminal and host computer, pre-install Handshake Protocol respectively, in the serial communication terminal, solidified the log-on message of this serial communication terminal simultaneously;
When the serial communication terminal connects host computer by serial ports, host computer is according to the available Serial Port Information that is pre-stored in storage unit, send handshake request to all available serial ports, if having the serial ports feedback of at least one to shake hands replys, then shake hands successfully, and set up with the serial communication terminal that this serial ports is connected down and to communicate by letter, delete in the available serial ports that this Serial Port Information is stored from storage unit simultaneously;
After communication is set up successfully, the serial communication terminal can send to host computer in log-on message wherein and registers solidifying, host computer is stored in the storage unit of host computer in the lump with the information of the log-on message of serial communication terminal and the serial ports that connected thereof, and registration is finished automatically.
Further, aforesaid serial communication terminal automatic registration method, the judgement of wherein said available serial ports is as follows:
Host computer is opened all serial ports successively, if can successfully be opened, illustrates that this serial ports can use, and the storage unit that simultaneously the string slogan of available serial ports is kept at host computer is standby.
Described serial communication terminal automatic registration method wherein also comprises:
After a serial communication endpoint registration was finished, host computer can repeat to send a handshake request to all available serial ports, if shake hands response feedback, and the then renewal of registration, otherwise, finish.
Described log-on message comprises at least a in the address, product type, production code member, firmware version number, product producer of communication terminal.
As preferred version serial communication terminal automatic registration method, host computer receives that the response time of shaking hands of serial communication terminal is between 0 millisecond to 5000 milliseconds.
As preferred version serial communication terminal automatic registration method, host computer receives that the response time of shaking hands of serial communication terminal is between 0 millisecond to 500 milliseconds.
As preferred version serial communication terminal automatic registration method, all serial ports numbers of host computer self are no less than 1.
As preferred version serial communication terminal automatic registration method, all serial ports numbers of host computer self are 2 to 10.
Described Handshake Protocol is as follows:
Serial communication terminal and host computer communication protocol are the ASCII character of 10 byte regular lengths, and protocol format is: AAA#BBB#CC, and wherein AAA is an instruction type, and BBB is operation, and CC is a parameter, and # is a blank character, can not have.
Instruction type comprises two kinds: CMD and DAT, CMD representative sends is instruction, the transmission of DAT representative be data.
When beginning to shake hands, host computer sends to the serial communication terminal:
CMD#CHK#00 represents whether host computer inspection serial communication terminal is normal;
After the serial communication terminal is received instruction, if the serial communication terminal normally sends to host computer:
CMD#CHK#OK ；
If the serial communication terminal is wrong, send to host computer:
CMD#ERR#XX?；
Annotate: XX is an error code.
Receive the CMD#CHK#OK of serial communication terminal transmission when host computer after, send Address requests to the serial communication terminal:
CMD#ADD#RE?；
When the serial communication terminal is received Address requests, send:
CMD#ADD#XX；
Annotate: XX is the ASCII character address, serial port terminal device address 00-99;
Host computer sends the log-on message request code to the serial communication terminal:
CMD#VER#RE；
When the serial communication terminal is received above-mentioned request, send:
CMD#?VER?#XX；
Annotate: XX is the ASCII character address, serial communication terminal code 00-99;
Host computer is to serial communication terminal transmits data request code:
CMD#REQ#XX；
Annotate: XX is the request of ASCII character data type;
When the serial communication terminal is received request of data, send the data length bag:
DAT#NUMXXX；
Annotate: XXX is an ASCII character packet number;
Next serial communication terminal transmission length is 10 packet, sends the back that finishes and sends:
CMD#DAT#OK;
The expression data send and finish.
