The power supply mode of the field data acquisition terminal can be DC power supply, colloidal battery and solar energy. Colloidal battery power supply is more subtle,it is not easy to be stolen, but its energy is limited, a charge can work 1 - 2 years (depending on the frequency of collection). Solar power supply lasted for a long time, but easily damaged. The DC supply voltage is stable for a long time, but it is susceptible to power outages. The above three kinds of power supply can be used as the specific situation. The solar power supply consists of three parts: a solar panel, a controller and a battery. Solar panels to solar energy into electricity at the same time to the battery charge, and then use the battery to the system power supply to form a stable power supply system.
