AI Technical Summary
In existing technologies, excessive or insufficient current consumption by field equipment leads to unstable communication and power supply, affecting the normal operation of the equipment and the operation of other equipment in the section.
A static current detector is used to measure the current consumption of the equipment circuit. With the help of a power regulator and microcontroller, the current is monitored in real time to see if it exceeds or falls below the threshold, and an alarm is issued to prevent equipment failure and communication interruption.
It enables real-time monitoring of field equipment, timely issuance of alarms, prevention of equipment malfunctions and communication failures within the section, and ensures normal equipment operation and power stability.
