[0082] In some embodiments, the IP addresses of the first network port and the third network port are the same, and the IP address of the second network port is different from that of the other two network ports.

[0083] See also Fig. 9 The working mode of this embodiment is: the first network port of the acquisition device, namely the LAN1 interface (acquisition port), is connected to the satellite vehicle station control device, and the third network port, namely the LAN3 interface, is connected to the corresponding switch to realize the forwarding of the original data flow. The acquisition device analyzes, filters and stores the collected data, and transmits the data to the military wireless transmission device through the second network port, namely the LAN2 interface (communication port).

[0084] The working principle of the present invention is as follows: turn on the "power" switch on the front panel of the acquisition device, connect the satellite device to start the acquisition work, the "work" indicator light flashes, and the data acquisition device is powered on. Turn off the "power" switch, and the data acquisition device is directly shut down. After the acquisition device is turned on, if it needs to be restarted, just press the "restart" button on the front panel of the device and wait for the device to restart. The data export mode of the data acquisition device is divided into two modes: network port data upload and USB mode export. When the network port data is uploaded, the storage server IP is adjusted to the same network segment as the LAN 2 port of the acquisition device, and the LAN 2 port of the acquisition device is connected to the data upload end. After the connection is completed, press the data upload button, and the data will be directly uploaded to the wireless transmission platform. When the USB mode is used for export, the mobile storage device is connected to the USB export interface on the rear panel of the acquisition device, and the "data export" button is pressed on the front panel to observe the indicator light status. The continuous flashing of the export display LED indicator indicates that the data is being exported; the long-on indicator indicates that the storage space of the mobile storage device is insufficient and the export operation cannot be completed; the extinguishing of the indicator indicates that the export has been completed or the export operation has not been performed.

[0085] After completing the data export, you can directly view the stored data in the storage address corresponding to the storage server, or connect the mobile storage device to the computer to query the data.

[0086] When special circumstances require, the collection device can destroy the collected data and delete all the data stored locally after collection. The operation steps are as follows:

[0087] 1) Press and hold the "Data Destruction" button on the front panel to make the data destruction indicator flash for 5 seconds;

[0088] 2) The data collection device starts to destroy the data, and the indicator light will change from flashing to long on;

[0089] 3) After all data is destroyed, the data destruction indicator light goes out.

[0090] The acquisition device can be modified by connecting to the serial port through the serial port debugging assistant and by connecting to the network port through the management software. When modifying by connecting to the serial port, the acquisition device can connect to an external computer through the debugging port, and the operation of the device can be queried through the serial port debugging assistant. At the same time, the IP and other parameters can be set through the serial port assistant. When modifying by connecting to the network port, the acquisition device can connect to an external computer through any network port and run the "Acquisition Device System Configuration.exe" program.

[0091] After starting the program, enter the user name and password in the program. The acquisition device IP is the IP address of the acquisition device network port connected to the computer. After entering, click "Login".

[0092] After successful login, click "Query Settings" to set the static IP of network port 1, the static IP of network port 2, and the IP of network port 3 of the acquisition device to the same as the IP of network port 1.

[0093] After the query is completed, you can modify the IP information directly through the program. The modification method is as follows:
