This summer, we received feedbacks that in some hot areas, the DNEST A/C system was not strong enough to cool down the temperature, and the drone cannot be charged safely.

    For this reason, we have been working non-stop on the development of solutions that will be implemented in our new products.

    Firstly, we've redesigned the air duct for cooling
    Secondly, we improved the ventilation for the A/C
    Thirdly, we installed a stronger A/C.
    Fourthly, we put more work into building smarter temperature control. We added a set of sensors. At the center of the pad, there's an infrared sensor to get the temperature of the battery. There is a set of temperature and humidity sensors for monitoring the temperature inside the canopy. There is also a set of temperature and humidity sensors at the air duct opening, which can sense the temperature of the wind from the A/C. Finally, there is a set of temperature and humidity sensors below the charging pad, where the main control unit is, to sense the ambient temperature. In the leg, there is also to be a temperature and humidity sensor for monitoring the drone remote control temperature. Then, based on the temperature, the wind speed and temperature can be adjusted accordingly.
    On the one hand, we achieve the fastest time to reduce the temperature to a safe temperature. Then start the battery charging. On the other hand, after the temperature has dropped down, we can also reduce the temperature and the power consumption of the A/C, to save power.
    Fifthly, a set of smoke sensors and fire extinguishers is installed. Under the charging pad, there is a smoke alarm next to a fire extinguisher that can be used to protect the main components. Why not protect against drone batteries? Because once the lithium battery is on fire, it is impossible to save, thus it's more important to protect the other parts.
    Sixthly, we also increased the gravity vibration sensor, so that you would know if the drone has returned onto the charging pad without the monitor camera image.
    Seventhly, at the bottom of the lower compartment, there is a flood sensor, used to sense whether there is water.

In addition, we have developed a new intelligent charging control module, and sensor control module, through this set of hardware upgrades, we can ensure a safer, energy-saving, and smarter charging station.
