[0034] The ARM single-chip microcomputer first acquires the longitude, latitude, heading and speed information of the ship through the serial port 5, i.e., the serial port connected to the Beidou short message communication navigation terminal, then packs the position information of the ship according to Table 1, and then sends the position information of the ship to the center platform system by using the Beidou satellite short message communication function through the serial port 5.

[0035] Further, the shore end center platform can send instructions through a short message to modify the time interval of the ship end timing position reporting information.

[0036] Further, two alarm buttons and a test button are installed to realize timely alarm and test of ship security. The alarm button connection includes two parts:

[0037] 1) is a 485 differential signal;

[0038] 2) power supply, which directly feeds the input power of the Beidou SSAS control box device to the alarm button.

[0039] The 485 two-wire differential signal can ensure that the alarm button supports the driving capability of 100-meter cable length.

[0040] Further, the alarm content is set as shown in Table 2.

[0043] Further, the alarm process is as follows:

[0044] Press the alarm 1 button for more than 1 second, at which time the alarm buzzer controlled by the Beidou SSAS will sound, and the alarm indicator will flash red.

[0045] After the alarm 1 button is triggered, the Beidou SSAS control box will fill in the relevant state data according to the alarm content in Table 4-1, and the destination address will be sent to the alarm short message information according to the "button 1 alarm destination address list" in sequence through the Beidou terminal A330.

[0046] After the alarm is triggered, the alarm information will be sent according to the maximum frequency interval of the card frequency, for example, the Beidou card is 60s, and the next destination address alarm information will be sent every 60 seconds.

[0047] After the alarm is triggered, the automatic position reporting function is temporarily suspended until the alarm task is completed and the Beidou is not over frequency.

[0048] After the last alarm destination address is sent, the buzzer stops sounding and the alarm indicator stops flashing after 2 seconds.

[0049] When the alarm occurs, the content is displayed as SSAS ALERT MESSAGE.

[0050] After the test button is pressed, the message sending principle is the same as above, but the buzzer does not sound during the alarm, and the test message is sent to the specified address above, and the type (TYPE) in the test message is displayed as TEST.

[0051] The specific information in the above Table 2 can be configured through a computer connected to the configuration port by a serial port line, and the APP software tool T006 of the computer is used to configure the information. It can also be configured through a Bluetooth connected mobile phone, and an Android mobile phone APP is used to configure through Bluetooth.
