2) Highly integrated design, providing aluminum alloy aviation aluminum box to put a full set of equipment, can be placed in the SUV (can be placed in the rear seat);

2. Customized features

2.1 Secondary power supply design

The secondary power supply is designed and manufactured by the drone company. The power supply weight is no more than 950g. The power supply time of all equipment is not less than 70 minutes (the peak power consumption of all equipment is 150W (at startup), the normal working power consumption is 110W), and the size can meet the mission cabin. Placed in, power supply operating temperature requirements: -20 ~ 50 ° C, provided by the party side of the power supply interface of each device (providing the specified interface form of the connection line), voltage, current, power consumption and other information.

2.2 Mission Cabin Design

1) The mission cabin is made by the drone company and can be placed under the nacelle cabin. The weight of the mission cabin is not more than 1kg, which is protected from light rain and easy to disassemble.

2) All equipment modules need to be placed in the mission cabin. Except for the secondary power supply, each equipment module is provided by us. The drone company makes a reasonable layout, and the drone company needs to do the electromagnetic compatibility between the equipments in the mission cabin. And heat treatment, so that each device can work normally;

3) The drone company provides the connection cable between the power source and each device and each device, and optimizes the cable routing connection between the device modules;
