[0052] The working principle of the rack-mounted reinforced chassis of the utility model is as follows:

[0053] Connect the relevant equipment on the submarine to the AD input interface and the amplifier output interface of the rack-mounted reinforced chassis respectively;

[0054] The staff presses the power switch, and the first power supply 10 supplies power to the back panel 2, the first heat sink 4, the second heat sink 12 and the voltage and current acquisition module 14, and the second power supply 11 supplies power to the power amplifier module 13;

[0055] The A device on the submarine transmits a certain a signal into the rack-mounted reinforced chassis through the AD input interface, and the voltage and current acquisition module 14 monitors the current / voltage fluctuation of the a signal and transmits the a signal to the acquisition filter board for noise filtering. After the acquisition filter board performs noise filtering on the a signal, the signal is transmitted to the main control board through the internal wiring of the backplane 2. The main control board sends a signal amplification instruction according to the received signal. The signal amplification instruction is also transmitted to the network communication module through the internal wiring of the backplane 2. The network communication module wirelessly transmits the signal amplification instruction to the power amplifier module 13. The power amplifier module 13 amplifies the noise-filtered a signal and transmits it to the B device on the submarine from the power amplifier output interface;

The main control board determines whether the voltage / current of the amplified signal exceeds the set value. If it exceeds, the buzzer is controlled to issue an alarm prompt.

[0057] Preferably, the network communication module not only has the above-mentioned signal transmission function, but also has the function of switching the network in the chassis and the function of remote power on and off.

[0058] When remote shutdown is required, the remote host is connected to the rack-mounted reinforced chassis through the remote host interface. When the shutdown operation is performed on the remote host, the shutdown command is sent to the network communication module through the remote host interface (the network communication module is connected to the remote host interface). The network communication module transmits the shutdown command directly to the backplane 2, and transmits the shutdown command to the main control board through the internal wiring of the backplane 2. The main control board sends a power-off command to the first power supply 10, and the backplane 2 powers off the main control board to achieve remote shutdown; at the same time, the network communication module controls the first power supply 10 and the second power supply 11 to turn off the power output and stop supplying power according to the shutdown command.

[0059] When remote startup is required, when the startup operation is performed on the remote host, the startup command is sent to the network communication module through the remote host interface.
