Deployment time
The integrated equipment has been integrated on the roof of the vehicle, does not need to be deployed separately, and automatically self-checks and enters the combat state under the control of the command and control system.
When the external power supply is normal and the parking is complete, the whole system is fully deployed to have working conditions, and 2 people are required, and the time is less than 30 minutes.

Use requirements
The system work site should meet the following conditions as far as possible:
1) The parking space can provide three-phase four-wire system 380V, 40kW stable power supply; If there is no power supply, the power supply vehicle equipped with the system can be used, or the oil engine can be used to generate power;
2) The parking area is empty, without dense high-rise buildings and trees;
3) The parking area should be far away from sensitive areas such as railways, high-voltage lines and airports;
4) There is no manpower requirement except for 2 operators.


Allocation proposal

Independent deployment of a single vehicle
If the defense area is small, such as within a detection radius of 5km and a strike radius of 1km, a single vehicle deployment method can be adopted. Each defense area is equipped with one laser anti drone system, which can be responsible for target detection within the surrounding 75 square kilometers and low altitude safety at important points within the core 3 square kilometers. An example is shown in the following figure:


Multi vehicle networking deployment
If the defense area is large or scattered, a multi vehicle networking deployment method can be adopted. Under the unified management and command of the command and control system, multi vehicle networking can be used to achieve target information sharing, unified threat assessment, task allocation and combat tasks.
The deployment mode can adopt a two-level command system of "1+N", which means "command center+N sets of systems". The command center can be deployed in a single vehicle, or in the command center, monitoring room, or fixed command post.
The command center can deploy the corresponding command system software modules, and the bicycle system does not require any other modifications.
