It should be noted that, in the electric power field, in order to reduce the storage of the monitoring data of the power distribution information management system on the related electric power equipment, a mode of acquiring a monitoring image at intervals of a preset time may be adopted. But each monitored image may be image coded in order to enable a time-line dimensional distinction of the monitored images.
And S103, if the first gateway monitors that the first communication link is restored to the normal state, the first gateway sends a second image code corresponding to the second monitoring image to the monitoring equipment.

Through the storage, when the monitoring image data is processed later, the relevant monitoring image which is not received under the fault state of the first communication link can be positioned in time through the first image code and the second image code.
In this embodiment, the external monitoring device uploads the monitoring image data to the monitoring terminal through the first communication link, when the first gateway monitors that the first communication link is in a fault state, the first image code corresponding to the first monitoring image is sent to the monitoring device, and when the first gateway monitors that the first communication link is restored to a normal state, the second image code corresponding to the second monitoring image is sent to the monitoring device, so that the monitoring terminal stores the first image code, the second image code and the monitoring image data read from the first communication link into the monitoring database, and when the monitoring image data is read and processed, the monitoring image data can be accurately positioned to the relevant monitoring image which is not received in the fault state through the first image code and the second image code.
Optionally, on the basis of the foregoing embodiment, the monitoring device may display the first monitoring image at the first time node, keep displaying the first monitoring image between the first time node and the second time node, and switch to display the first monitoring image at the second time node, so as to avoid that the monitoring device displays a black screen or a screen switching failure interface due to no input image in a period of time when the first communication link is in a failure.

Specifically, the image code corresponding to the time point corresponding to the preset time period after the first gateway monitors that the first communication link is restored to the normal state may be used as the second image code, and the image code is sent to the monitoring device after the first gateway monitors that the first communication link is restored to the normal state. The monitoring terminal stores the first image code, the second image code, and the monitoring image data read from the first communication link into a monitoring database. Through the storage, when the monitoring image data is processed later, the relevant monitoring image which is not received under the fault state of the first communication link can be positioned in time through the first image code and the second image code. The external monitoring equipment uploads the monitoring image data to the monitoring terminal through the first communication link, when the first communication link is monitored to be in a fault state through the first gateway, the first image code corresponding to the first monitoring image is sent to the monitoring equipment, and when the first communication link is monitored to be restored to a normal state, the second image code corresponding to the second monitoring image is sent to the monitoring equipment, so that the monitoring terminal stores the first image code, the second image code and the monitoring image data read from the first communication link into a monitoring database, further the image acquired by the external monitoring equipment is read by the power distribution room gateway, and the image codes under the period of failure of the link are stored so as to quickly locate and complement the missing monitoring image later. On the basis of the above embodiment, the monitoring terminal may further display the first monitoring image at the first time node, keep displaying the first monitoring image between the first time node and the second time node, and switch to display the first monitoring image as the second monitoring image at the second time node. Thereby avoiding that the monitoring terminal displays a black screen or a stuck image due to the failure of the communication link. It is worth to say that, can also keep displaying the first monitoring image between the first time node and the second time node, further display the prompt message that the communication link has failed, the first image code and the first time node, thereby make the staff record above-mentioned information, so that follow-up manual work carries out quick location and completion of the lost monitoring image.

Therefore, the monitoring terminal can collect data of various power equipment in real time through the gateway of the distribution room, and the data comprise information such as monitoring images, real-time current, real-time voltage, real-time power consumption, electric energy metering, switching states and the like. Moreover, since different devices may use different communication protocols, the distribution room gateway may also implement conversions between multiple protocols, such as Modbus, IEC104, DL/T645, etc., so that the upper management system can uniformly process and parse such data.

By means of the breakpoint transmission mode, the integrity of monitoring data transmission of the external monitoring equipment under the condition of poor network state can be guaranteed.

In another specific design, the external monitoring device may also be a fixed monitoring camera. If the first gateway monitors that the number of times that the first communication link is in a fault state exceeds a preset number of times threshold in the data transmission process that the external monitoring device sends the retransmission monitoring image sequence to the monitoring terminal through the first communication link, the external monitoring device stops transmitting the retransmission monitoring image sequence.

And the other external monitoring device determines a replacement monitoring image sequence according to the first time node and the second time node, and sends the replacement monitoring image sequence to the monitoring terminal through the second communication link. The monitoring terminal generates complete monitoring image data according to the monitoring image data and the replacement monitoring image sequence, and stores the complete monitoring image data into a monitoring database, so that the monitoring image acquired by another external monitoring device is used for replacement, and the integrity of the monitoring image is improved in emergency.
And S208, the monitoring terminal responds to the monitoring playback instruction, the complete monitoring image data is displayed in the monitoring terminal, and the target missing interval is identified on an indication progress bar for representing the playback progress of the complete monitoring image data.
