Fig. 2-7 are respectively the structural representations of six modules of the utility model, and the parts of modules form and signal transmission relation describes in detail in utility model content, are not described in detail in this.
In Fig. 8, front panel left side vessel motion situation indicating section is used in inclination direction and the draft situation of panel instruction boats and ships.In the time that the inclination angle of boats and ships a direction is greater than setting threshold ("Left"-deviationist, Right deviation, lean forward, hypsokinesis), the inclination angle pilot lamp of respective direction can glimmer respectively and send chimes of doom, in the time that the draft of boats and ships is greater than setting threshold, overweight pilot lamp can glimmer and send chimes of doom.Front panel right-side device operation conditions indicating section is used to refer to the running status of equipment.When equipment normally moves, the normal bright indicating equipment of run indicator normally moves.In the time that equipment has corresponding fault (inclination angle fault, water level fault, record trouble, location fault), corresponding pilot lamp is bright and send chimes of doom, and remote monitoring module sends indicating fault to remote server simultaneously.
In Fig. 9, extract after boats and ships data, the ship trajectory of dynamic drafting boats and ships in the map that can carry in client (seeing black line in figure), have the function that warning information gathers, data message shows and checks, reports to the police and report to the police instruction, in map, black line is the ship trajectory of dynamic drafting simultaneously.Supervision department, by using the client software of server, can monitor the violation situation of boats and ships.
Figure 10 is the program flow diagram of an embodiment of the utility model, and instrument uninterruptedly carries out work, and each step that reruns comprises following several step:
Step 1, after instrument powers on the operation of real-time monitoring system power supply and storage area whether normal, send alerting signal if undesired, enable standby power supply, and warning message be sent to remote server.If normal, go to step 2.
Step 2, the data that receiving angle measurement module, depth survey module, GPS module, storage battery administration module, remote monitoring module send, whether the data that judge each module transmission are normal, if the undesired failure alarm signal that sends corresponding module continues to receive corresponding module data.If normal, go to step 3.
Step 3, extracts respectively the effective information of Angle Measurement Module, depth survey module, GPS module, storage battery administration module, remote monitoring module.Extract remote monitoring module effective information, and carry out instruction.Obtain GPS module effective information, and forward step 4 to.Judge that whether power supply running status is normal, if undesired, forward step 1 to, if normally forward step 4 to.Judge whether the degree of depth, angle-data exceed alarm threshold value, if so, send report to the police corresponding instruction and alarm, forward step 4 to, if not, directly forward step 4 to.
Step 4, is stored to local spatial by the data of extracting, and sends data to remote server.Again going to step 1 reruns.
Below in conjunction with a specific embodiment, equipment is described.
The threshold value of the deep draft degree of depth of equipment is made as to 1 meter, leans forward, the angle threshold of hypsokinesis, "Left"-deviationist, Right deviation is made as 40 degree, equipment is installed on sandstone ship A.After device power, storage inside module in mainframe box starts the draft data of real time record A ship, all around inclination data, ship trajectory data, the warning message data of direction, these data are sent to remote server by remote monitoring module simultaneously, and deposit the database in server in.The video data recording that the outer memory module of equipment monitors video monitoring module in real time preserves, and by remote monitoring module, video data transmitting is delivered to remote server simultaneously, and deposits server database in.
A ship is adopted in the process of sand operation at Tuo Jianghedao, and when equipment normally moves, the normal run indicator of mainframe box front panel is bright, and other pilot lamp go out.
The angle leaning forward when A ship is greater than 40 while spending, and mainframe box sends alarm sound, pilot lamp flicker that what mainframe box front panel was corresponding lean forward, and the equipment warning message that will lean forward is stored in mainframe box storage inside module, and is sent to remote server.Until A ship forward leaning angle is less than after 40 degree, device replied is to normal operating condition.The situation of hypsokinesis, "Left"-deviationist, Right deviation is with leaning forward.
Heavy excessive while causing draft to be greater than 1 meter when A boat-carrying, mainframe box sends alarm sound, the overweight pilot lamp flicker that mainframe box front panel is corresponding, and overweight warning message is stored in mainframe box storage inside module by equipment, and be sent to remote server.Until A ship draft is while being less than 1 meter, device replied is to normal operating condition.
In the time that equipment Angle Measurement Module breaks down, mainframe box sends alarm sound, the inclination angle flicker of fault indicating lamps that mainframe box front panel is corresponding, and normal run indicator is gone out, and failure message is sent to remote server.Until Angle Measurement Module is while normally working, device replied is to normal operating condition.
The corresponding same Angle Measurement Module of situation when the depth survey module of equipment, mainframe box storage inside module, mainframe box GPS module break down.
In the time of equipment generation power fail, storage battery administration module starts standby power supply, and mainframe box sends alarm sound, all pilot lamp flickers of mainframe box front panel, and power failure information is sent to remote server.Until device power supply (DPS) is when normal, device replied is to normal operating condition.
Regulator is in the client of remote server, can real-time video the situation of supervision boats and ships, and the obliquity information of real time inspection boats and ships, draft information, underway position information, warning message, device fault information, all data can show in client end interface.Client provides map function, can be in map the ship trajectory of dynamic drafting boats and ships.
The video data that is stored in server database, obliquity information, draft information, underway position information, warning message, device fault information etc. can be called at any time by server client by regulator.
