Among them, DSP1 is responsible for receiving the data from the AD acquisition transmission board and the network data from the host computer and packaging them, and sending them to DSP2. At the same time, it is responsible for environmental background noise monitoring and processing, and transmits the MGC parameters to the front conditioning module through GPIO. DSP2 is responsible for passive beamforming and downsampling, and transmits data to DSP3. DSP3 is responsible for passive noise data PAS, BTR, TNI, LOFAR, DEMON, and tracking processing; DSP4 is redundant and reserved for backup.

[0031] The AD acquisition transmission board performs analog-to-digital conversion and real-time acquisition of the conditioned electrical signals transmitted by the two pre-conditioning boards, and transmits the digital signals to the signal processing board through the Gigabit network. The main parameters are: onboard high-performance domestic Fudan Micro JFM7K325T logic chip, domestic ADC chip CX74E1; sampling rate 96k, 4ms per frame of data; signal amplitude consistency less than 1dB, signal phase consistency less than 1°; input power supply ±12V.

[0032] The main function of the pre-conditioning board is to amplify and filter the element-domain acoustic-electrical signals from the acoustic array, and at the same time receive the GPIO signal (MGC) transmitted by the signal processing board to perform manual gain control, adjust the signal amplification factor, and transmit the pre-processed signal to the AD acquisition and transmission board. The input power supply is ±12V, ±5V.

[0033] The isolated power supply inputs one 220V AC power and outputs two isolated 220V AC power.

[0034] The power board 1 inputs 220V AC and outputs 3 sets of DC low-voltage power supplies, one for the main control module ±12V; one for the signal processing board ±12V; and one for the AD acquisition and transmission board ±12V.

[0035] The power board 2 inputs 220V AC and outputs 2 sets of DC low-voltage power supplies (±12V, ±5V) for use by the pre-conditioning board.

[0036] The components used in portable integrated devices (including core chips, resistors, capacitors, inductors, crystal oscillators, diodes and other devices) are all domestic components, and the materials used are also domestic materials.

[0037] The portable integrated device chassis is made of stainless steel 316L material, and the color of the chassis is medium green-gray. There are two handles on the left and right sides of the chassis, and four feet are designed below. The touch screen and keyboard are installed on the front side of the chassis, with a folding function, and the LCD screen is installed on the front side of the chassis.

[0038] Install a small plug-in box behind the LCD screen and fix it to the bottom plate. On the motherboard of the small plug-in box, parallel and straight-plug the power board 1, the main control board, the signal processing board, the AD acquisition transmission board (separated by metal isolation boards on the left and right), two pre-conditioning boards, and the power board 2. The cover of the small plug-in box is flush with the upper surface of the all-in-one machine. Install the isolated power supply on the right side of the small plug-in box.

[0040] The method of using the portable integrated device is as follows, and the flow chart is shown in Figure 5 .

[0041] The portable integrated device is connected to the underwater acoustic array through aviation plugs 1 and 2, and connected to the 220V power supply through the power aviation plug. After starting up, the 220V external AC power is divided into two 220V isolated AC power through the internal isolated power supply, and supplies power to power board 1 and power board 2. Power board 1 and power board 2 supply power to other boards and modules inside the device, and the device starts up normally. The host computer starts up automatically and displays on the LCD screen. Set the MGC parameters on the host computer interface and transmit them to the signal processing board to control the pre-conditioning board. The pre-conditioning board is responsible for amplifying and filtering the received array element domain acoustic-electrical signals, and transmitting them to the AD acquisition transmission board for analog-to-digital conversion and real-time acquisition, and then transmitting them to the signal processing board through the Gigabit network. The signal processing board receives the command parameters issued by the main control board host computer and the digital signals transmitted by the AD acquisition transmission board, and is responsible for signal processing of the collected signals, and finally sends the processing results to the host computer for display (including PAS, BTR, TNI, LOFAR, DEMON, and environmental background noise monitoring format). In the PAS format, double-click the target to track the target and display the tracking result in the tracking format. Double-click in the tracking format to cancel the tracking target. Click the left mouse button + the number 1 key at the same time in the PAS format to monitor targets in different azimuth channels. The upper computer interface will display the TNI, LOFAR, and DEMON results of the corresponding azimuth channels. When you finish using it, shut down the main control board normally according to the normal shutdown process of the laptop, and then turn off the power.
