Abstract
The utility model provides a digital converter of an analog signal gyrocompass. The digital converter comprises an analog signal input interface, a communication module, a microcontroller, a power module, a keyboard input module, an LED (Light Emitting Diode) display module, a digital tube display module and a display driving circuit, wherein an output signal of the gyrocompass is changed into a 0/1 logic signal, which can be recognized by the microcontroller, by the analog signal input interface; then an acquired signal is counted and operated by the microcontroller; and an operation result is simultaneously displayed through the LED display module and the digital tube display module and is simultaneously transmitted to a data bus through the communication module. According to the digital converter, digital display and transmission of the gyrocompass are realized; and the digital converter has the advantages of high indication accuracy, no noise, intuitive and clear indication, small size, light weight, capability of arranging plurality of repeaters and the like.
Description
Technical field
The utility model relates to a kind of simulating signal gyrocompass digitizer, belongs to the navigating equipment technical field.
Background technology
In recent years, along with the development of shipbuilding industry, development is demanded in navigating equipment manufacturing field urgently.Have in the gyrocompass that uses at present is to use the simulation selsyn as the critical component of signal transmission greatly.With the stairstep signal of its generation or the synchronizing signal driving signal as the rear class repeater compass, its signal proportion is 90: 1,180: 1 or 360: 1.But modern electronic devices is based on fieldbus, the signal that it can receive mostly be RS485 or RS422 signal, original simulating signal can't be for these equipment.Based on this background, designed this simulating signal gyrocompass digitizer.
Summary of the invention
The utility model provides a kind of simulating signal gyrocompass digitizer for the deficiencies in the prior art.
Simulating signal gyrocompass digitizer of the present utility model is by the following technical solutions:
Simulating signal gyrocompass digitizer comprises analog input interface, communication module, microcontroller, power module, keyboard load module, LED display module, charactron display module and display driver circuit.Analog input interface becomes the output signal of gyrocompass into 0/1 logical signal that microcontroller can be identified, then calculation process is counted and done to microcontroller to the signal that collects, operation result shows simultaneously by LED display module and charactron display module, sends on the data bus by communication module simultaneously.When this converter powers on or long-play when occur showing deviation for the first time, can pass through its displayed value of keyboard load module correction.
The utility model has realized that the digitizing of gyrocompass shows and transmission, has the pointing accuracy height, noiselessness, indicate visual and clear, the advantage such as volume is little, and is lightweight.And because the data transmission of this converter is based on the RS485 bus, each converter can be worn a plurality of repeater compass indicators.
Description of drawings
Fig. 1 is the structural principle schematic block diagram of the utility model simulating signal gyrocompass digitizer.
Among the figure: 1, keyboard load module, 2, analog input interface, 3, microcontroller, 4, communication module, 5, display driver circuit, 6, the LED display module, 7, the charactron display module, 8, power module.
Embodiment
As shown in Figure 1, the output signal of simulating signal gyrocompass mostly is three-phase stairstep signal or synchronizing signal, and its principle that realizes indication is used the corresponding motor of this signal driver exactly, thereby drives the dial plate rotation, realizes that registration shows.Therefore as long as the signal of its output is counted, just can calculate current output valve.Simulating signal incoming analog signal input interface 2 with gyrocompass output, 0/1 logical signal that this interface can become the analog-signal transitions of 110V microcontroller 3 can directly process, after microcontroller 3 reads this logical signal from the IO mouth, through tabling look-up computing, can judge the state that current compass is in forward or counter-rotating, and the angle of its rotation is counted.So just can calculate current indicated value.Then this indicated value can show by LED display module 6 and charactron display module 7 simultaneously by display driver circuit 5, and this displayed value also outwards transmits by communication module 4 simultaneously.By the digital signal of communication module 4 transmission, meet the format specification of NMEA0183, use HDT statement and ROT statement pattern.When this converter when deviation appears in upper point or long-play for the first time, can revise by keyboard load module 1.Can also set by keyboard load module 1 in addition the type of input signal.Power module 8 be with on the ship+the 24V direct supply is transformed into the stabilized power source that system needs, for each module.
Claims (1)
