Abstract

The invention relates to a method for mainboard troubleshooting through internet access connecting equipment. The method comprises the following steps that a serial port TX, a serial port RX, a serial port VCC and a serial port GND of a mainboard to be checked are connected into an eight-pin internet access; 2, a nine-pin serial port in a computer is connected to the eight-pin internet access of the mainboard to be checked through a corresponding serial-port-to-internet-access line; 3, the mainboard to be checked is normally powered on, and all the operating states of software of the mainboard are normally displayed in the serial ports after starting up; 4, after the Baud rate, data bits, odd-even check and the stop bit provided by research and development are set on a computer through a connected serial port line, serial port information of the mainboard to be checked is printed; 5, the current operating state of the software is checked through the serial port of the computer, and a command is normally input for troubleshooting. The method has the advantages that the serial-port-to-internet-access line is connected to the internet access to achieve troubleshooting, it is avoided that a shell is dismounted to accidentally damage a bare board, and research and development cost can be reduced.

Description

A kind of method connecting equipment mainboard investigation fault by network interface

Technical field

The present invention relates to the software issue of a kind of equipment mainboard investigation method, particularly relate to a kind of method connecting equipment mainboard investigation fault by network interface.

Background technology

Current hardware designs all can reserve serial ports row array interface on mainboard, facilitate research and development of software personnel can go to get rid of software issue by serial ports, check running software situation, process etc. in positioning software, but owing to the Position Design of serial ports is unreasonable, generally require and the shell of hardware device is opened, connect serial ports detection again, electronic device on mainboard is all very little, it is easy to by accidental damage, damage some electronic device and may result in the appearance of many unpredictable problems, serious whole mainboard all can be burned, so will certainly have influence on software development progress, and then add the cost of exploitation.

Realize rs 232 serial interface signal either directly through network interface input and output by this method, it becomes possible to avoid opening shell and cause to the injury of electronic device on mainboard, and then the progress of research and development of software exploitation can be promoted, it is possible to save the cost of exploitation.

Summary of the invention

It is an object of the invention to provide a kind of method connecting equipment mainboard investigation fault by network interface, solve and when main board failure is investigated by prior art, need to open device housings, the problem that the electronic device on mainboard easily causes because touching by mistake damaging.

For solving the problems referred to above, the technical solution used in the present invention is:

A kind of method connecting equipment mainboard investigation fault by network interface, comprises the following steps:

1). the serial ports TX of mainboard to be checked, serial ports RX, serial ports VCC, serial ports GND are connected respectively in 8 pin network interfaces;

2). 9 needle serial ports on computer are turned network interface Serial Port Line by corresponding serial ports and is connected to 8 pin network interfaces of mainboard to be checked;

3). mainboard to be checked normally powers on, mainboard to be checked from start after all of running status of software normally show from serial ports;

4). the Serial Port Line by connecting on computers, after arranging the baud rate of research and development offer, data bit, even-odd check, stopping position, will print the Serial Port Information of mainboard to be checked;

5). checking, by the serial ports of computer, the running status that software is current, normal input instruction carries out malfunction elimination.

Adopt and have the beneficial effects that produced by technique scheme:

1, serial ports pricking with needle need not be additionally added in production, decreases a material, has saved production cost, is also avoided that this material is bad with other material product caused that collides in process of production;

2, the model machine made will not damage because of electronic device and cause that model machine work is abnormal, affects research and development of software and goes orientation problem, has saved the cost of research and development of software exploitation;

3, the later stage also can connect serial ports very easily for the new problem that software produces and investigate, and fast and easy positions and the problem of solution.

4, the line being turned network interface by serial ports is connected on network interface and realizes investigation, causes the unexpected injury to bare board without removing shell, it is possible to save R&D costs.

Accompanying drawing explanation

Fig. 1 is the schematic flow sheet of a kind of method being connected equipment mainboard investigation fault by network interface of the present invention.

Detailed description of the invention

In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.

Fig. 1 illustrates an embodiment of a kind of method being connected equipment mainboard investigation fault by network interface of the present invention: a kind of method connecting equipment mainboard investigation fault by network interface, comprises the following steps:

1). the serial ports TX of mainboard to be checked, serial ports RX, serial ports VCC, serial ports GND are connected respectively in 8 pin network interfaces;

2). 9 needle serial ports on computer are turned network interface Serial Port Line by corresponding serial ports and is connected to 8 pin network interfaces of mainboard to be checked;

3). mainboard to be checked normally powers on, mainboard to be checked from start after all of running status of software normally show from serial ports;

4). the Serial Port Line by connecting on computers, after arranging the baud rate of research and development offer, data bit, even-odd check, stopping position, will print the Serial Port Information of mainboard to be checked;

5). checking, by the serial ports of computer, the running status that software is current, normal input instruction carries out malfunction elimination.

In above-described embodiment, SecureCRT is a terminal emulator supporting SSH (SSH1 and SSH2), is briefly the software logging in UNIX or Linux server main frame under Windows. In figure, debug is investigation fault.

Research and development of software turns the line of network interface by 9 needle serial ports and is connected to the network interface of model machine and carries out software investigation. Software test personnel test in customers' place, it has been found that turning the line of network interface by 9 needle serial ports during problem and be connected to the network interface of model machine and capture the Log information that research and development of software personnel need, be then sent to research and development, orientation problem is gone in help research and development.

Although reference be made herein to invention has been described for the multiple explanatory embodiment of the present invention, but, it should be understood that those skilled in the art can be designed that a lot of other amendments and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.
