Detailed Description

In order to more clearly illustrate the present invention, embodiments of the present invention are further described below with reference to the accompanying drawings.

As shown in fig. 1, the main control module adopts an STM32F407VGT single chip microcomputer produced by the semiconductor company of the law as a main control chip, and the main functions of the main control module are as follows: 1) receiving data acquired by ship data AIS receiving modules connected to pins 92 and 93 of the single chip microcomputer, analyzing, processing and storing the data; 2) the picture analysis module connected to the 47 th, 52 th, 53 th and 54 th pins of the single chip microcomputer analyzes and processes the pictures acquired from the intelligent camera and transmits the related data of the analysis and processing to the single chip microcomputer; 3) the singlechip combines the picture processing data to send the required related data to the upper computer of the appointed IP address port through the 4G module.

As shown in fig. 2, the ship data AIS receiving module circuit and the picture analysis module circuit have the main functions: 1) the ship data AIS receiving module actively acquires ship data according to a specified frequency; 2) the intelligent camera has a mobile detection function, takes ship pictures of a mobile ship in a defined area at proper intervals, and transmits the pictures to the picture analysis module; 3) the picture analysis module analyzes the ship picture information and informs the main control module of corresponding data.

As shown in fig. 3, the 4G communication module adopts a 4G communication module EC20 of a remote company as a communication transceiver, and the EC20 module adopts the LTE 3GPP rel.9 technology; the maximum downlink rate of 100Mbps and the maximum uplink rate of 50Mbps are supported; multiple Input Multiple Output (MIMO) technology is supported, so that the error rate is reduced, and the communication quality is improved; the high-speed wireless connection and the built-in multi-constellation high-precision positioning GPS + GLONASS receiver are combined; the built-in rich network protocol, integration of multiple industry standard interfaces, and support of multiple drivers and software functions (such as Windows XP, Windows Vista, Windows 7/8/8.1/10, USB driver under Linux, Android and other operating systems, etc.)

The 67 th pin and the 68 th pin (high level 1.8v and low level 0 v) of the EC20 module and the 63 th pin and the 64 th pin (high level 3.3v and low level 0 v) of the single chip microcomputer STM32F207 realize data transceiving and command transmission in the mode of an AT instruction set through a level conversion chip TXS0108 EPWR.

Pins

14, 15, 16 and 17 of the EC20 module are respectively connected with

pins

1, 6, 3 and 2 of the SIM card socket chip, so that the EC20 module and the SIM card perform 4G data interaction.

Pin 49 of the EC20 module is connected to the 4G antenna. PWR _ EC20 is connected with pin 60 (P _ CTRL) of the singlechip through triode Q1 and resistors R8 and R9 to control the on and off of the EC20 module, when P _ CTRL is low level, the EC20 module is in a non-operating state, and when P _ CTRL is high level, the module is in an operating state, and normal data communication can be carried out. NET _ L is an indication signal output by the EC20 module 4G network, when NET _ L is at high level, the indicator lamp D1 is on, when NET _ L is at low level, the indicator lamp D1 is off. When the indicator light is turned on for 200 ms/turned off for 1800ms, the EC20 module is in a network searching state; when the indicator light is turned on for 1800 ms/turned off for 200ms, the module EC20 is in a standby state; when the indicator light is turned on for 125 ms/turned off for 125ms, the module EC20 is in a 4G data transmission state; when the indicator light is on for a long time, the module EC20 is in a call state.
