Head-mounted display device and communication command system

A communication command system, comprising a head-mounted display device and a command terminal, wherein:

• the head-mounted display device and the command terminal are communicatively connected;
• the head-mounted display device includes:
• a head-mounted display portion and a control portion connected to the head-mounted display portion by signal;
• the control portion includes a main battery, an auxiliary battery, and a switching circuit module connected to the main battery and the auxiliary battery;
• and the switching circuit module is used to switch power supply between the main battery and the auxiliary battery;
• the switching circuit module includes a first trigger connector and a second trigger connector having a first state and a second state;
• in the first state, the first trigger connector and the second trigger connector are in an off-state, and the main battery supplies power;
• in the second state, the first trigger connector and the second trigger connector are in an on-state to trigger a switching signal to switch to the auxiliary battery for power supply;
• the head-mounted display portion includes a head-mounted bracket, a display module and a camera module located in the head-mounted bracket;
• the head-mounted bracket includes a glasses frame, two glasses arms, and a webbing connected between ends of the two glasses arms away from the glasses frame;
• the two glasses arms include a first glasses arm and a second glasses arm;
• a main driving board is arranged in the first glasses arm;
• the main driving board is connected to the control portion through a signal connection line;
• the main driving board is connected to a camera driving board of the camera module through a first adapter circuit board;
• the camera driving board is arranged in the second glasses arm;
• the main driving board is connected to a display drive board of the display module through a second adapter circuit board;
• and
• the eyeglass frame includes a first sub-frame and a second sub-frame stacked in a light emitting direction of the display module;
• the first sub-frame and the second sub-frame are interlocked to form an accommodating cavity;
• the first adapter circuit board and the second adapter circuit board are accommodated in the accommodating cavity, and one end of the first adapter circuit board extends into the first glasses arm to be connected to the main driving board, and one end of the second adapter circuit board extends into the first glasses arm to be connected to the main driving board.
