A programmable logic controller (PLC) is an industrial digital computer that has been widely applied in numerous manufacturing processes including smart robotic devices. Drone charging dock as a tiny portion of these applications has been seriously considered to use PLC due to its stable performance and ease to program. HEISHA K100 is applied to DNEST drone in-a-box (DIAB) solution, drone charging pads, and drone docking stations series by installing into the internal space flexibly, which is not easy to be achieved by PLC due to the size issue. Now the DNEST has realized the compatible charging of 3S 4S batteries to work for different brands of drones, which is also a challenge to PLC. There is another important part that is unique to a drone charging station, the air conditioning system. Your drone charging system will become huge if you purchase the air conditioner part from the market, but tailored it by PLC would be tricky. “ As special as HEISHA drone charging stations is ...
