As shown in fig. 2, the method includes:
step 110: the upper computer divides the online upgrading data into a plurality of data frames and sequentially sends each data frame to the lower computer.
The upper computer can divide the online upgrading data into a plurality of data frames according to a preset framing mode, and each data frame is respectively sent to the lower computer according to preset interval time. Furthermore, the upper computer can display the data frame sending progress on a display interface of the upper computer according to the total number of the data frames and the number of the sent data frames so as to be referred by maintenance personnel. Before sending the first frame data frame, the upper computer may send an upgrade command frame to the lower computer to notify the lower computer to start receiving the data frame, or the upper computer may add identification information to the first frame data frame to notify the lower computer to start receiving the data frame.
Step 120: and the lower computer receives each data frame sent by the upper computer in sequence, updates abnormal frame information when detecting that the data frame sent by the upper computer is abnormal, continues to receive the rest data frames sent by the upper computer, and displays the abnormal frame information after receiving.

The lower computer can comprise a lower computer display interface, and the lower computer can display the abnormal frame information on the lower computer display interface so that maintenance personnel can acquire the abnormal frame information through the lower computer display interface and input the abnormal frame information into the upper computer. For example, the lower computer display interface may be a 6-digit display pipe, which identifies the abnormal data frames as data frames with frame number 0 to data frames with frame number 29 by displaying "F00-29". If the lower computer display interface is a 2-bit digital display tube, 00 to 29 can be flash-displayed in sequence to identify the abnormal data frame as a data frame with a frame number of 0 to the data frame with a frame number of 29.
Step 130: and the upper computer receives the abnormal frame information input by maintenance personnel, determines a data frame needing to be retransmitted according to the abnormal frame information, and sends the data frame needing to be retransmitted to the lower computer.
Wherein, the host computer can include host computer display interface, and maintainer can be with unusual frame information input host computer display interface. The upper computer can acquire the abnormal frame information from the display interface of the upper computer and determine the data frame needing to be retransmitted according to the acquired abnormal frame information. For example, if a maintainer inputs "F00-29" on a display interface of an upper computer, the upper computer may analyze that the abnormal data frames are from a data frame with a frame number of 0 to a data frame with a frame number of 29, and determine that the data frame with the frame number of 0 to the data frame with the frame number of 29 are data frames that need to be retransmitted.

The lower computer can continue to receive the data frames which are sent by the upper computer and need to be retransmitted. In the process of receiving the data frame needing to be retransmitted, identifying the data frame as a normal data frame and updating abnormal frame information for the successfully received data frame; for the data frame with failed reception, the data frame is still retained in the abnormal frame information. Further, the lower computer can display the updated abnormal frame information to maintenance personnel, so that the upper computer sends the data frames with failed reception again until all the data frames sent by the upper computer are successfully received.
In the embodiment of the invention, an upper computer is connected with a lower computer in a simplex communication mode, the lower computer can sequentially receive each data frame sent by the upper computer, when the data frame sent by the upper computer is detected to be abnormal, abnormal frame information is updated, and the remaining data frames sent by the upper computer are continuously received until the receiving is finished; then, the lower computer displays the abnormal frame information to display the abnormal frame information to maintenance personnel, so that the maintenance personnel can input the abnormal frame information into the upper computer; the upper computer can determine the data frame needing to be retransmitted according to the abnormal frame information and send the data frame needing to be retransmitted to the lower computer; the lower computer can continue to receive the data frames needing to be retransmitted, and after the data frames needing to be retransmitted are received, online upgrading is executed.

Step 220: and when the data frame sent by the upper computer is detected to be abnormal, updating abnormal frame information.
The abnormal frame information is used to record identification information of the data frame with the abnormality, such as a frame number of the data frame with the abnormality.
Step 230: and continuously receiving the residual data frames sent by the upper computer.
When the lower computer detects that the data frame sent by the upper computer is abnormal, the lower computer discards the abnormal data frame and continues to receive the residual data frame sent by the upper computer, in the process of receiving the residual data frame, the data frame which is successfully received is stored to the specified position of the memory, the data frame which is failed to be received is discarded, and the abnormal frame information is updated again.

and the lower computer continuously receives the data frame needing to be retransmitted, and after the data frame needing to be retransmitted is received, online upgrading is executed.
7. An online upgrading method is characterized in that the online upgrading method is applied to a lower computer of an online upgrading system, the system comprises an upper computer and the lower computer, the upper computer is in communication connection with the lower computer in a simplex communication mode, and the method comprises the following steps:
sequentially receiving each data frame sent by the upper computer;
when the data frame sent by the upper computer is detected to be abnormal, updating abnormal frame information;
continuously receiving the residual data frames sent by the upper computer;
when the receiving is finished, displaying the abnormal frame information;
continuously receiving the data frame which is sent by the upper computer and needs to be retransmitted;
and after the data frame needing to be retransmitted is received, performing online upgrading.
8. The method of claim 7, wherein the data frame comprises a total number of data frames, a current frame sequence number, current frame data, and current frame check data, the method further comprising:
determining the frame sequence number of the data frame lost according to the total number of the data frames and the current frame sequence number, and storing the frame sequence number of the data frame lost as the abnormal frame information; and/or the presence of a gas in the gas,
and determining the frame sequence number of the data frame with the error check according to the current frame data and the current frame check data, and storing the frame sequence number of the data frame with the error check as the abnormal frame information.
9. The utility model provides an online upgrading device which characterized in that, is applied to in the lower computer of online upgrading system, the system includes host computer and lower computer, the host computer through simplex communication mode with the communication connection is established to the lower computer, the device includes:
the receiving module is used for sequentially receiving each data frame sent by the upper computer;
the detection module is used for detecting whether the data frame sent by the upper computer is abnormal or not;
the updating module is used for updating abnormal frame information when the detection module detects that the data frame sent by the upper computer is abnormal;
the receiving module is further configured to continue to receive the remaining data frames sent by the upper computer after the updating module updates the abnormal frame information;
the display module is used for displaying the abnormal frame information after the receiving module finishes receiving;
