• Storage temperature: －20℃～55℃

• Relative humidity of the whole vehicle: (95±3)% (at 40℃)

2.5 Design Principles

• The equipment compartment and seats inside the vehicle are made of high-strength metal material with plastic-sprayed surface (beige color). Silicone rubber shock absorbers are installed when fixing the equipment compartment and seats to the vehicle body. The rated bearing capacity of the shock absorbers is determined according to the total weight of the equipment compartment with installed equipment, and the surplus bearing capacity of the shock absorbers is between 8% and 13% of the actual bearing capacity, giving full play to the effect of silicone rubber shock absorbers to achieve an optimal overall shock absorption effect for the equipment compartment and seats.

Vehicle Fire Resistance

• The interior decoration of the command vehicle is mainly steel decoration with a small amount of wood decoration. Steel decoration has strong fire resistance; wood decoration is processed according to the shape of the vehicle body and strictly following woodworking painting processes and procedures to ensure smooth and beautiful lines, fire retardancy and environmental protection inside the vehicle, complying with YD/T5003-2005 Design Specifications for Telecommunication Special Buildings for processing to ensure safety.

• The interior filling materials, floor and other interior materials and auxiliary materials of the vehicle adopt flame-retardant, anti-static and environmentally friendly materials without harmful substances such as formaldehyde and benzene. The floor uses imported anti-static plastic floor with anti-skid and wear-resistant performance, which has no thermal expansion and contraction problem, keeping the floor flat and beautiful regardless of the temperature change inside the vehicle.

Vehicle Safety

• All performances of the command vehicle have undergone strict commissioning with qualified inspection reports issued by professional institutions.

• The load of the vehicle is strictly configured in accordance with the allowable load of the vehicle body chassis.

• The external dimensions of the vehicle body and the configuration of roof equipment strictly comply with the relevant vehicle management systems of the ministry.

Equipment Safety

• The safety requirements for the equipment inside the vehicle comply with the relevant provisions of GJB663-89.

• The command vehicle adopts an air circuit breaker with leakage protection device as the main power switch to prevent personal injury caused by equipment leakage and damage to equipment caused by line overload and short circuit faults.

• Attention is paid to the self-protection function of the equipment in configuration; all selected equipment can make corresponding protection actions in case of failure, effectively improving the stability and reliability of the system.

Information Security

• Equipped with independent communication transmission means to ensure the reliability and security of information transmission in any harsh working environment.

• Encryptors or firewalls can be used in the process of information transmission and reception to ensure the security of data transmission.

• All system software has encryption functions; users can select encrypted files according to their own requirements to prevent data loss and theft and ensure information security.

Grounding Design

• Three types of grounding points must be set on the vehicle body: equipment safety grounding, vehicle body protection grounding and lightning protection grounding. Beryllium bronze grounding rods are used for grounding.

• Equipment grounding and power supply grounding are collected at the cabinet grounding copper bar with equal-length grounding wires; the computer is grounded independently. A large cross-section flat copper wire is connected to the "protection column" of the external interface board of the vehicle body to form a closed equipotential system.

• All grounding wires are copper insulated wires with a cross-section of not less than 4mm².

• When the structured cabling system uses shielded cables for wiring, the grounding of information sockets can use the cable shielding layer as the grounding wire connected to the distribution cabinet of each floor.

• If the cables of the structured cabling are laid through steel pipes or metal trunking, the steel pipes or metal trunking shall maintain continuous electrical connection and be well grounded at both ends.

2.6 Waterproof and Anti-Corrosion

1. Optimization in Design: Optimize anti-corrosion design, and improve the corrosive environment. Attention shall be paid to the optimization of metal parts in terms of part structure selection, material matching, rationality of structural layout, rationality of structural connection, and prevention of gap generation.

2. Optimization in Materials: Improve the thermodynamic stability of materials, adjust the alloy composition of part materials, increase anode polarization, etc.; replace existing ordinary materials with materials with strong anti-corrosion performance, or with non-corrosive materials such as aluminum-magnesium alloy and engineering plastics.

3. Optimization in Coating: Improve the coating of metal parts and enhance electrochemical protection; replace ordinary paint coatings with coatings with strong anti-corrosion performance (e.g. cathodic protection, anodic protection, Dacromet coating); add protective coatings to the gaps, interlayers and cavity bottoms of parts.

4. Optimization in Processes: Formulate reasonable manufacturing processes for parts to prevent bumps and scratches during manufacturing, and adopt manufacturing processes and measures that do not damage the protective layer as much as possible.

2.7 Fastening Performance

• Reinforced skeletons are added on both sides and the top of the vehicle body for support; the side wall skeleton and top skeleton are connected with the antenna support skeleton, so that the acting force of the internal and top parts of the vehicle is fully applied to the skeleton and floor, ensuring the anti-torsion, anti-shear deformation and anti-seismic capacity of the refitted vehicle.

• To ensure the fastening of the vehicle inner wall, important parts inside the vehicle body are reinforced with steel pipe profiles and elbows, and high-strength steel skeletons are used for welding reinforcement during the vehicle processing.

• A buffer gasket is installed between the mounting surfaces when assembling the antenna mounting base and the antenna; the processing tolerance of the antenna mounting base is formulated according to the specific requirements of the microwave antenna.

• U-shaped steel plate profiles and welding processes are used at the antenna positions on the top inside the vehicle to ensure the good structural strength of the original vehicle roof and improve the local bearing capacity of the vehicle roof.

• The vehicle roof adopts an aluminum structure with patterned aluminum plates paved on the platform surface for anti-skid performance; a circle of 3mm thick aluminum plate guard plate processed according to the shape of the vehicle roof with a closed edge is installed around, which has anti-skid performance, sufficient bearing capacity, uniform force, beautiful appearance, meets the use strength requirements and has good corrosion resistance, satisfying the installation requirements of roof-mounted equipment.

• The vehicle roof is designed with drainage and is equipped with a stainless steel low fence.

2.8 Vehicle Body Balance Design

1. Through the rational layout inside the vehicle, the front and rear axle load distribution of the refitted vehicle is controlled within the vehicle technical requirements.

2. In the layout of equipment, both axle load distribution and the left and right counterweight requirements of the vehicle are highly valued to ensure that the center of gravity of the vehicle is always within a reasonable range and the vehicle is safe and stable during travel.

3. After the final confirmation of all equipment, the balance of the vehicle will be calculated, and the layout of the equipment will be fine-tuned according to the calculation results to maximize the satisfaction of the vehicle's driving requirements and the convenience of equipment operation.

4. After the completion of the vehicle body, the load-bearing test of each point of the wheels is carried out to clarify the bearing capacity of each point, so as to ensure the overall counterweight balance of the whole vehicle during parking and driving, and ensure the reasonable and balanced axle load and stable driving of the refitted vehicle.
