Problems solved by technology
[0011] The first purpose of the present invention is to provide a method for obtaining the operating state of the device, which is used to solve the problems that the existing serial communication is normal but cannot obtain the operating state of the embedded device, and it is difficult to deal with faults and locate faults, so as to realize the embedded device system software When a fault occurs, the operating status of the device can be obtained, and the fault can be quickly located and handled
[0012] The second object of the present invention is to provide a device for obtaining the operating status of equipment, which is used to solve the problems that the existing serial communication is normal but cannot obtain the operating status of embedded equipment, and it is difficult to process and locate faults. Obtain the operating status of the system to quickly locate and handle faults
[0013] The third purpose of the present invention is to provide a system for obtaining the operating status of equipment, which is used to solve the problems that the existing serial communication is normal but cannot obtain the operating status of embedded equipment, and it is difficult to deal with and locate faults, so that it can still be used when the equipment fails. Obtain its running status to quickly locate and handle faults

Embodiment Construction
[0036] see Figure 4 , is a flow chart of an embodiment of the method for obtaining the operating state of the device in the present invention. Such as Figure 4 As shown, this embodiment includes:
[0037] Step 1. The terminal judges whether the command input by the device to the serial port does not return information, and if so, sends preset detection information to the device serial port, and performs step 2; otherwise, judges the operating status of the device according to the returned information, and ends;
[0038] Step 2. After the device serial port receives the preset detection information; directly read the device running status, and send the running information including the device running status through the device serial port;
[0039] Step 3. The terminal obtains the running state of the device according to the running information;
[0040] The detection information is preset information that directly reads the operating status of the device and is different f...

The present invention discloses, through several embodiments, a method for obtaining the running state of a device, a device for obtaining the running state of the device, and a system for obtaining the running state of the device, wherein the method includes: the terminal does not receive a command input by the device to the serial port. When returning information, the preset detection information is sent to the serial port of the device; after receiving the detection information, the serial port of the device directly reads the running state of the device, and sends the running information including the running state of the device through the serial port of the device; the terminal according to the running information Get the operating status of the device. The embodiments of the present invention solve the problems that the existing serial port communication is normal but cannot obtain the running state of the embedded device, and it is difficult to deal with and locate the fault, realize that the running state of the device can be obtained when the software of the embedded device system fails, and the fault can be quickly located. and handling failures.
