The communication methods of the cable sheath circulation monitoring system are diverse, including the public network4GCard, power, wireless4GAnd wired communication, etc.

Communication failures may be caused by various factors, such as weak wireless signals, communication module failures, and public networks4GCard arrears or wireless power supply4GUnstable network (for wireless communication), as well as damaged or loose wired lines (for wired communication).

The impact of communication failures on system functionality

1. Data transmission interruption or delay

The most direct impact of communication failure is the interruption or delay of data transmission.

If the real-time data generated by the monitoring system, such as the waveform and amplitude of the grounding current, cannot be transmitted to the monitoring platform in a timely manner, it will cause maintenance personnel to be unable to grasp the cable operation status in a timely manner, increasing the risk of accidents.

2. Remote monitoring and operation are restricted

The cable sheath circulation monitoring system supports remote viewing function, allowing maintenance personnel to receive real-time monitoring data through handheld devices and perform remote operations.

Communication failure will result in the failure of this function, and maintenance personnel will not be able to obtain critical information or perform remote control in a timely manner, affecting the speed of emergency response.

3. Automatic alarm function failure

The system has an automatic alarm function, which can automatically trigger an alarm when the grounding current transient increases or suddenly decreases to zero.

However, communication failures may result in alarm messages not being delivered to maintenance personnel in a timely manner, preventing potential security risks from being addressed in a timely manner.

4. System self diagnosis and maintenance efficiency decrease

Although the self diagnostic function of the system mainly relies on local detection, communication failures may affect the upload of self diagnostic results, making it difficult for the monitoring platform to obtain system status information in a timely manner.

This will reduce system maintenance efficiency, increase the difficulty and workload of on-site inspections.

Response measures and suggestions

To reduce the impact of communication failures on the cable sheath circulation monitoring system, it is recommended to take the following measures: firstly, regularly inspect the communication modules and lines to ensure that they are in good condition; The second is to choose a stable and reliable communication method, such as dual-mode communication (wireless)+Wired); Thirdly, establish an emergency communication mechanism to ensure that the primary communication mode can be quickly switched to the backup mode when it fails; The fourth is to strengthen the monitoring of the system's self diagnostic function, timely detect and handle communication failures.

The impact of communication failures on cable sheath circulation monitoring systems is multifaceted and may pose serious safety hazards.

Therefore, it is necessary to attach great importance to the prevention and handling of communication failures, ensuring the stable operation of the system and the safety of power cables.
