It has a wide range of application scenarios, including emergency rescue, large-scale event support, etc. It can provide real-time and smooth communication and command and dispatch support in various complex environments. The emergency command and communication box is a portable comprehensive business command box, mainly used for on-site command and communication dispatch. It has audio and video acquisition, wireless transmission, video conferencing, command and dispatch and other functions. It can be interconnected with audio and video terminals and command centers through multiple network links to provide real-time, smooth and stable communication guarantees. When responding to emergencies, front-line personnel usually need to carry emergency command and communication boxes to the scene, transmit on-site information through the emergency command and communication boxes, and give timely commands.

[0003] A search of CN114205800A discloses a communication device for emergency command, comprising a box body and a box cover, wherein the box cover is provided on one side edge of the box body for circumferential rotation; sliding members are provided on both sides of the box cover for transverse sliding, and the other end of the sliding member is provided on the adjacent side edge of the box body for transverse sliding; the present invention improves the traditional communication device by providing a sliding member between the box body and the box cover, and using a supporting mechanism and a pushing member in conjunction with the use of the supporting mechanism and the pushing member, when the user opens the box cover, the pushing member is driven to make a transverse displacement by the sliding of the sliding member, and then the supporting mechanism is pushed downward by the pushing member to expand the supporting mechanism, thereby raising the horizontal height of the box body, making it more convenient for the user to operate and view the command site conditions, and the construction efficiency is high, and the user's time is not wasted, and the operation utilizes the rotational movement of the box cover as a power source, and no external power source is required for starting.
