Because the pipelines are distributed far away, the pipeline stress and strain acquisition equipment is generally also of a distributed structure and is characterized by a large number of equipment and incapability of being concentrated. Data of the pipeline stress detection point is also remotely transmitted to a monitoring center server, and the transmission distance is dozens of kilometers if the transmission distance is short and thousands of kilometers if the transmission distance is long. The field acquisition equipment works in an unattended field area, is difficult to supply commercial power and can only be supplied by solar energy and a large-capacity battery. The acquisition equipment needs to work all year round, so the requirement on low power consumption is higher.

Although a radio station can perform communication over a long distance, its transmission power must be increased to a certain level, which increases the power consumption of the system. On the other hand, the cost of the sending end and receiving end equipment of the radio station is also high.

The 2G/4G has achieved a large application due to reliable technology, fast transmission speed, and unlimited communication distance, but the greatest problem is that the power consumption is high, and particularly, the peak current of the 2G/4G reaches over 300mA during data transmission.
In the aspect of system power supply, a scheme of increasing capacity of a battery by solar energy is generally adopted at present, but the problem is that the purchase cost is high, and in some areas in the south, rainy weather can continuously appear, so that the working requirement of a solar panel cannot be met. The application of the system is limited.
In view of the above problems, no effective solution has been proposed.
