Present invention law enforcement ship terminal contains a 433MHz radio-frequency communication modules with operation ship terminal, by the communication module
Local communication is carried out using single channel protocol, realizes that the information between operation ship and law enforcement ship is mutually passed, single channel agreement (on
Row is with downlink data by the same communication channel of same 433MHz radio-frequency communications module) it is to be set based on hardware and certain parameter
Realized on the basis of fixed, the communication time interval information of least unit T=200ms, i.e., two send interval need 200ms with
It is upper just to avoid two collision errors of information, but it refers to that operation ship terminal sends letter to law enforcement ship terminal that channel communications are up
Breath, descending refers to that law enforcement ship terminal sends information to operation ship terminal；Law enforcement ship terminal and operation ship terminal must be by respective
The Big Dipper time dissemination system of BDS/GPS locating modules unifies time service；Time interval unit under 200ms, single channel agreement
433MHz radio-frequency communication modules must are fulfilled for following condition：
Signal bandwidth sets value：500KHZ
Preposition FEC entangles code check value：CR 4/5
Spreading factor value：9
Channel sets value：4
Transmission power value：20dBm
Serial port baud rate value：38400
Below for a law enforcement ship patrols and examines example, operation ship is fishing boat, and single channel agreement law enforcement cycle time T is 1 minute, association
Section task is detailed such as table 1 when discussing each：
Single channel communications protocol is to be respectively provided with a 433MHz radio-frequency communication based on law enforcement ship terminal and operation ship terminal
Module, upstream and downstream data passes through a same communication channel for 433MHz radio-frequency communication modules, ship terminal of being enforced the law when up
433MHz radio-frequency communications module as transmitting terminal, the 433MHz radio-frequency communications module of operation ship terminal as receiving terminal, now
Information can only have law enforcement ship to be sent to information ship, then conversely, be so avoided that information is mutually collided when descending, according to agreement
Sequential is communicated, so operation ship terminal is reported to law enforcement ship successively, it is in good order, and and the relative used time is slightly long.
Above-described embodiment and schema and non-limiting product form of the invention and style, any art it is common
Appropriate change or modification that technical staff is done to it, all should be regarded as not departing from patent category of the invention.
