Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present utility model relates to a kind of digital loxodograph, as shown in Figure 1, comprise single-chip microcomputer, gyro compass, locating module, display module and printer module, described single-chip microcomputer links to each other with locating module, gyro compass, display module and printer module respectively; Described gyro compass is used for obtaining the course signal of boats and ships; Described locating module is used for obtaining the positioning signal of boats and ships; Described single-chip microcomputer is used for receiving course signal and the positioning signal of described boats and ships, and the signal of receiving is handled; Described display module is used for showing the result of described single-chip microcomputer processing; Described printer module is used for printing the result that described single-chip microcomputer is handled, and only just prints when course data changes.Wherein, gyro compass can be digit Electric Compass, and links to each other with single-chip microcomputer by the RS485/422 interface, and gyro compass also can be the analog electrical compass, and links to each other with single-chip microcomputer by analog to digital converter.Described locating module is the GPS locating module, can realize the GPS positioning function by adopting high sensitivity, low power consumption chip StarIIIGPS receiving chip.Described display module is LCD display.Described printer module is mini-printer.
Course of the present utility model is printed and is adopted storage back printing type earlier, if the course remains unchanged always, then printer is not printed, and can save recording chart; The utility model is got the corresponding accommodation of course change point (being the longitude and latitude of turning point) and time simultaneously with the form of tables of data, conveniently read the course of each turning point, can analyze boats and ships state at that time; Time signal of the present utility model is taken among the GPS information, so recording chart is the common blank form of non-professional format, when changing recording chart need not to the time, convenient and swift.
Digital loxodograph of the present utility model has three interfaces.The signal of GPS locating module and digit Electric Compass is to send loxodograph to by digital interface.GPS locating module interface adopts RS232C or RS485/422 form; The digit Electric Compass interface adopts the RS485/422 form.Consider the applicability of loxodograph, still using the analog electrical compass on present many boats and ships.The course signal of analog electrical compass is by analog electrical compass signal converting unit, with the biography of traditional electrical compass to than be one of 360,180,90,45,36 synchronously or the stepping course signal be converted to the NMEA-0183 data, send the single-chip microcomputer processing unit.In fact, analog electrical compass signal converting unit is exactly a single-chip data disposal system, its various false course signals with the traditional electrical compass carry out digitizing, export to the single-chip microcomputer processing unit with NMEA-0183 data layout (baud rate is 4800b/s) at last.
Digital recorder of the present utility model parses time data and prints the time in the tabulation as the course from the signal of GPS.Deposit current accommodation, time, course in storer as an array element simultaneously, the time interval of data storages is 10 minutes (or 5 minutes, can select).Singlechip data processing unit compares with last next-door neighbour's array based on one group of current data, if course data does not change, then current data is write the storage unit of last next-door neighbour's data, does not print.Variation has taken place in the course of two adjacent groups data, storage current data and time-write interval, boat position and course tabulation.
The course signal of analog electrical compass of the present utility model is carried out the A/D conversion through analog electrical compass signal converting unit, according to not simultaneous interpretation to than and signal type (according to not coordination FFO or the ON of the type selecting DIP switch of gyro compass), adopting algorithms of different with data sampling and after handling, is that the NMEA-0183 data layout of 4800b/s sends to the single-chip microcomputer processing unit with the baud rate.
Using method of the present utility model is as follows: the signal of GPS directly inserts the GPS interface of registering instrument.The course signal of digit Electric Compass is direct linkage record instrument interface also.If be the traditional electrical compass, then according to the model of gyro compass DIP1 and the DIP2 of registering instrument done some selections.DIP1 selects signal type " synchronously " and " stepping "; DIP2 select to pass to than.Before energising is used, carry out some settings with reference to following explanation and get final product.
This machine of opening can be seen a toggle switch DIP1 in the printing board PCB bottom, and then there is one 4 DIP switch DIP2 in the lower right corner, sees shown in Figure 2.
Toggle switch is the setting of stepping and synchronize changer:
When using synchronous compass, switch is allocated to " SYNC " position;
When using the stepping compass, switch is allocated to " STEP " position.
4 DIP switch are the setting of synchronous compass multiplying power switch:
When synchronous compass was 360X, switch as shown in Figure 3;
When synchronous compass was 180X, switch as shown in Figure 4;
When synchronous compass was 90X, switch as shown in Figure 5;
When synchronous compass was 45X, switch as shown in Figure 6;
When synchronous compass was 36X, switch as shown in Figure 7.
The characteristics of digital loxodograph of the present utility model are: 1, numeral shows course and accommodation in real time; 2, with time, course and accommodation be the formal print record course numeral of tables of data, ocular and simple; 3, adopt the storage printing type, when steady, not printout, thus save paper; 4, owing to cancelled many mechanical parts in traditional loxodograph, use common recording chart and need not to the time, so Operation and Maintenance is more convenient.
