Description

technical field [0001] The invention relates to the field of electric power, in particular to a mobile remote power monitoring system and monitoring method based on a 4G network. Background technique [0002] The power monitoring system (hereinafter referred to as the SCADA system) realizes the centralized management and scheduling, real-time control and data collection of the power supply system in the control center (OCC). In addition to using the "four remote" (remote control, remote signaling, remote measurement, remote adjustment) functions to monitor the operation of power supply system equipment, and to grasp and deal with various accidents and alarm events in the power supply system in a timely manner, the background workstation of the system can also Perform data archiving and statistical report functions on the system to better manage the power supply system. [0003] With the development of computer and communication technology, since the late 1990s, computer-bas...

AI Technical Summary

Problems solved by technology

[0005] 1. Inaccurate early warning: Due to the error of the sensor and the normal fluctuation of the power equipment system, it will lead to the abnormality of the obtained parameters, which will lead to false alarms of the entire system

Lead to inaccurate early warning, resulting in unnecessary waste of human resources

[0006] 2. The amount of information obtained is small: because the existing power monitoring system obtains pure data information, although problems can be found to a certain extent from these data information, it is still not intuitive enough

In some cases, based on pure data information, it is difficult to determine the extent and cause of failure

[0007] 3. Unreliable network transmission: Many power facilities and equipment are installed in remote places and mountainous areas. The quality of network transmission in these places is generally very low. The traditional power monitoring system uses GPRS data transmission. If the signal is not good, it is very difficult. It may lead to the failure to warn in time

[0008] 4. The monitoring is not timely: power maintenance involves a lot of outdoor operations. In many cases, the staff can only contact the monitoring personnel through the mobile phone they carry to solve the fault.

This will not only lead to untimely acquisition of fault information, but also increase the difficulty of maintenance
