Communication command vehicle
1.Vehicle Description:
（1）Overview
| The communication command vehicle is used for emergency rescue operations and can be the first to arrive at the scene for command during the rescue. It is a mobile command center system equipment based on vehicles. In vehicle modifications, no changes are made to the key assemblies of the chassis (such as the engine, front axle, rear axle, etc.), which do not affect the stability, smoothness, braking of the chassis. For SUV models, non-destructive modifications are preferred, and no body sheet metal is welded. All modifications are installed
All parts are bolted to ensure that the modified parts are detachable, and there are no changes to the original chassis structure after the modification. The communication command vehicle produced by our company is based on the Maxus SH5043XXYH7DB-S chassis, which has a manual-automatic transmission, a maximum speed of 150km/h, an engine model of SC20M150Q6, an engine displacement of 1996ml, and emission standards of National VI. The fire communication command vehicle is based on the Datong SH5043XXYH7DB-S chassis as the modification platform, ensuring that the staff have a spacious and comfortable working environment and providing environmental conditions that meet technical requirements for the operation and maintenance of the system. Modified while maintaining the excellent performance of the vehicle, it is a special vehicle tailored to the working environment and functions that meet the user’s requirements. Fire communication command vehicles are equipped with communication networking capabilities and command communication and intelligence information collection functions. With high-definition, low-light on-board pan-tilt cameras, all-weather, multi-directional, wide-range on-site monitoring can be achieved. Through the vehicle-mounted hard disk recorder, real-time video and audio recording of the scene can be made for future investigation, and it can be connected to other storage devices via USB interface and data port for on-site burning, facilitating the timely and effective preservation of video materials. The vehicle-mounted LCD TV can centrally display the information collected by the system, allowing leaders to have real-time access to various situations at the scene of the incident Command and dispatch in a timely manner and make correct decisions. The vehicle performance complies with technical Conditions for the operation safety of motor vehicles (GB7258-2017), Dimensional limits of Motor vehicles (GB1589-2016), GB 50054-95 Code for Design of Low-voltage Power distribution; The overall dimensions, axle loads and mass of the vehicle shall comply with the provisions of GB1589-2016 “Limits of Dimensions, Axle Loads and Mass of Road Vehicles”; The whole The vehicle is designed to comply with Code for Design of Fire Communication and Command Systems (GB 50313-2013). |
