With the development of the smart grid, wireless communication plays an important role in this application. The smart grid needs to constantly measure the voltage, power current, etc and send them to the control center in real-time. The traditional manual measurement method cannot ensure timeliness and timely feedback.
Climate change or bad weather can cause errors, troubles, and accident in the grid system. Manual detection is time-consuming and laborious and cannot transmit the information to the control center timely, may bring heavy economic loss.
Smart grid system involves humidity & temperatures sensors, current lead sensors, PLC local meter reading, and monitoring, solar panel power, etc and needs to observe if all the parameters are within the scheduled limits in time.
- 4G high-speed of M2M devices such as 4G LTE cellular modems or LTE cellular routers
- Hardware watchdog to maintain connectivity stability, data transmission timely
- Send the data to a control center by M2M device via the cellular network. Automatically running with minimum human intervention
Cellular network communication and automated/remote maintenance are key factors in the smart grid system. Usually adding wireless features is the first step to change the conventional grid to the smart grid.
