Abstract
A kind of ship gyrocompass control device, comprise master compass, described master compass input end connects digital signal controller and power supply transverse box, master compass output terminal connects digital compass repeater, master compass output terminal exports course digital signal and is connected transmission case in course with course simulating signal, and described course sends case output terminal connecting analog repeater compass and digital load.Simulation and digital course signal can be exported simultaneously, meet user's needs, improve equipment interoperability, be used to indicate carrier relative to the course between geographic meridian.
Description
Technical field
The utility model relates to a kind of ship gyrocompass control device.
Background technology
Current ship gyrocompass, needs first to be drawn by gyro main shaft to be biased near stable point before startup gyroscope, so that within a short period of time stablizes, if it is comparatively large to depart from true course when starting, stabilization time will be very long; Tradition course sends case can only export false course signal, and along with the widespread use of digital load, the applicability that course sends case is not strong.
Tradition liquid floated gyroscope compass is reach the object comparatively fast stablizing compass bearing, the method that stabilization process generally adopts long and short period to switch.Namely after smoothing, enter short period compass duty, after close to stable point, enter long period compass use duty.The stabilization time of the stationary mode compass of this program is generally at 1.5 ~ 2 hours.
Utility model content
Its object of the utility model is just to provide a kind of ship gyrocompass control device, can export simulation and digital course signal simultaneously, meet user's needs, improves equipment interoperability, is used to indicate carrier relative to the course between geographic meridian.
Realize above-mentioned purpose and the technical scheme taked, comprise master compass, described master compass input end connects digital signal controller and power supply transverse box, master compass output terminal connects digital compass repeater, master compass output terminal exports course digital signal and is connected transmission case in course with course simulating signal, and described course sends case output terminal connecting analog repeater compass and digital load.
Compared with prior art the utility model has the following advantages.
By comprehensive startup control program, stabilization time when wide-angle starts greatly can be shortened; Increasing digital conversion plate by sending out in case in boat simultaneously, making it to export simulation and digital course signal simultaneously, meeting user's needs, improving equipment interoperability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this device control principle schematic diagram;
Fig. 2 is comprehensive startup control flow schematic diagram in this device.
Embodiment
Comprise master compass, as shown in Figure 1, described master compass input end connects digital signal controller and power supply transverse box, master compass output terminal connects digital compass repeater, master compass output terminal exports course digital signal and is connected transmission case in course with course simulating signal, and described course sends case output terminal connecting analog repeater compass and digital load.
Embodiment
This device is used to indicate carrier relative to the course between geographic meridian, course can be sent case by course simultaneously and be transferred to each multiple installation with the form of analog quantity and digital quantity, so that each needs position to check current course at any time at boats and ships.
Also the equipment of needs can be supplied to as input signal (as radar, auto navigator etc.) to the course signal of each compound device.
By the Monitoring and Controlling in start-up course, realize wide-angle fast and stable, greatly accelerate gyrocompass stabilization time.
On master compass, digital display amount window can directly read course value, and away from the cabin of compass room, course value is shown by digital or analog repeater compass.
During with analog repeater compass, course need be configured and send case and power supply transverse box, often overlap course and send the analog repeater compass in case maximum Ke Dai 12 tunnel, as more multi-load need be with, course sends between case can cascade, if needed, by increasing digital conversion plate, course can be allowed to send case and to export course simulating signal and course digital signal simultaneously.
As shown in Figure 1, the simulation export master compass and digital signal are sent into course simultaneously and are sent in case, amplified by digital conversion and simulating signal, realize the function being simultaneously with dynamic simulated and digital load, in Fig. 1,1 is input ac power AC220V/50Hz, 2 is input DC power DC24V, 3 is input DC power DC24V, and 4 is input ac power AC110V/50Hz, and 5 is digital signal, 6 and 7 is course digital signal, and 8 is course simulating signal.
As shown in Figure 2, comprehensive stable control program, when compass can be made to start on any course, stabilization time is in 120min.
Adopt 1/4 periodic Control fast and stable to be used time the shortest control method in stable scheme, no matter main shaft initial position is northwards or southwards, by determining the position of main shaft during smoothing to the identification of pendulum signal voltage, thus realizes the object of comprehensive fast and stable compass.
Pendulum signal voltage U after the smoothing of gyro main shaft
bbe corresponding relation between fleet angle Δ K, measure U
bvalue just knows the size of Δ K, but serious gradually in wide-angle non-linear hour degree, and site error becomes large.
The structure of comprehensive control program is made up of a master routine and three feedback processes, ± 30 ° depart within only run through a master routine, after a master routine and a feedback process, all will enter master routine after being greater than this value again run once, control flow as shown in Figure 2.
