Technical field:
The utility model relates to embedded echosounder display system peculiar to vessel, particularly a kind of echosounder display system embedded peculiar to vessel based on ARM.
Background technology:
As everyone knows, can normally navigate by water in water in order to make boats and ships, bottom of ship must keep certain safety distance with the bottom in navigation channel, and this is commonly referred to as the depth of water more than needed apart from us.When having only the depth of water more than needed to reach certain requirement, boats and ships could safety pass through.In order accurately and timely to detect the depth of water situation in navigation channel, echosounder, particularly large ship generally all are housed on the modern ships, this equipment is installed aboard ship as standard configuration.Its major advantage is that video picture is directly perceived, and easy to use, location survey is more accurate.
Just be based on above reason, the student of ship-handling specialty must learn the proper operation method of echosounder before the practice of going on board.But because echosounder telltale peculiar to vessel is mostly by external manufacturer production, cost is relatively more expensive, acquire the echosounder telltale so educational institution and steamship company all need to spend a no small cost, and the maintaining cost of import equipment is very high mostly.Along with the development of microcontroller technology, the application of microcontroller in the ship's navigation technology is also more and more wider, and microcontroller data transmission and processing data ability can satisfy the needs of echosounder data handing, demonstration.
The utility model content:
The utility model is at the existing defective of above-mentioned existing echosounder telltale, and provide a kind of can convenient, flexible collection depth signal and handle that the back shows and to the system of remote transmission, it can realize the demonstration of depth signal, satisfies ship's navigation and daily teaching demand.
In order to achieve the above object, the technical scheme that the utility model adopted:
A kind of embedded echosounder display system peculiar to vessel, this system comprises signal acquisition process module, ethernet interface module and serial RS232 interface module; It is characterized in that, described signal acquisition process module receives by Ethernet interface or serial RS232 interface module and meets depth signal, gps signal, course and speed of a ship or plane signal and these outward signs of water temperature signal that NMEA0183 agreement (being formulated by American National ocean Institution of Electronics, is a kind of of GPS communications protocol) requires; Simultaneously signal is carried out necessary Filtering Processing, and the most various signal shows with figure or digital form.
In the such scheme, described signal acquisition process module is made up of embedded microcontroller, display control module and LCD MODULE; The input end of embedded microprocessor connects the input end of display control module by control line; The input/output terminal of display control module connects the mouth of embedded microprocessor and the input end of LCD MODULE by control line; The input end of LCD MODULE connects the mouth of display control module by line.
In the such scheme, the signal acquisition process module can outwards send the filtering data of handling well by connecting the routine data communication port.
In the such scheme, described system uses CPLD (Complex Programmable Logic Device CPLD), and as display control module, this display control module is controlled LCDs by firmware programs.
Microcontroller in the such scheme adopts embedded-type ARM framework microcontroller.
The echosounder display system a kind of novel embedded peculiar to vessel that the utility model provides, adopted a scheme easy, practical, that use is flexible, cost performance is high, can in real time various data be carried out long-range transmission by ethernet/serial RS232 interface, in addition current advanced microcontroller technology is incorporated in the total system, improved data-handling efficiency, make things convenient for use, reduced cost.
The utility model is except that having common signal acquisition process functions such as the depth of water, owing to used the microcontroller built-in type technology, and by ethernet/serial ports RS232 interface data are carried out remote live and send, make that total system is used more flexibly, cost is cheaper, in many occasions, can replace existing echosounder display system.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the system that the utility model adopts, total system by ARM microprocessor 1, Ethernet interface 2, RS232 interface module 3, display control module 4, LCD MODULE 5, form.
Wherein, microcontroller 1 input/output terminal connects the mouth of outward sign 6,7,8,9 and the input end of display control module 4 by universal network interface 2 or RS232 interface 3; The input/output terminal of network interface 2 and RS232 interface 3 is connected the mouth of the outward sign that comprises depth of water incoming signal 6, GPS incoming signal 7, course/speed of a ship or plane signal 8, water temperature signal 9 and the input end of microprocessor 1 by signal wire (SW); The input/output terminal of display control module 4 connects the signal output part of microprocessor 1 and the signal input part of LCD MODULE 5 by line; The input end of LCD MODULE 5 connects the mouth of display control module 4 by line.
When the native system that obtains according to technique scheme is specifically implemented, adopt microcontroller 1 to be used as the master controller of signal acquisition process transmission, be responsible for the coordination of total system work by it.At initial phase, microcontroller is configured ethernet/serial RS232 interface by software, and the control display control module shows various information on liquid crystal display.
Then, after microcontroller is finished initial work, just begin to wait for various outward signs.All outward signs all adopt NMEA0183 coded system (this signal standards agreement is not given unnecessary details at this).When digital sampling and processing receives after the data that ethernet/the RS232 interface transmits, just carry out the decoding Filtering Processing of data.Finally, microprocessor shows with figure or digital mode various signals such as the depth of water, GPS and water temperature by sending instruction to display control module at LCD MODULE.
