Problems solved by technology

However, because ordinary carbon brush potentiometers are easily affected by factors such as moisture, salt spray, and temperature in the steering gear cabin, there are often phenomena such as display failure and pointer drift, which seriously affect navigation safety.
[0006] 3) Self-aligning machine type rudder angle indicators and digital coded rudder angle indicators are easily affected by the vibration of the hull due to their complex technology, and the higher the accuracy, the higher the cost. Almost invisible in the market

Embodiment Construction

[0021] Such as figure 1 Shown, a kind of rudder angle indicator with video and electronic compass display, comprises rudder angle sender 7, touch screen display 8, is provided with potentiometer 2, temperature sensor 3, video image in said rudder angle sender 7 Acquisition module 4 and single-chip microcomputer and data acquisition module 6, described rudder angle sender 7 is connected touch-screen display 8. The rudder angle transmitter 7 is connected to a touch screen display 8 through a communication cable 9 . The rudder angle transmitter 7 is a fully sealed structure. The potentiometer 2 is a high-precision conductive plastic potentiometer.

[0022] The single-chip microcomputer and the data acquisition module 6 collect the angle of the steering gear in real time from the high-precision conductive plastic potentiometer, collect the temperature in the rudder angle cabin from the temperature sensor 3, and collect the real-time video images in the rudder angle cabin from th...

Abstract

The invention discloses a rudder angle indicator with video and electronic compass display, which comprises a rudder angle transmitter and a touch screen display. A potentiometer, a temperature sensor, a video image acquisition module, a singlechip and a data acquisition module are arranged in the rudder angle transmitter. With the adoption of the rudder angle indicator, a pattern of a pointer-type rudder angle meter can be directly simulated on a display screen by using an advanced touch type display screen; and the rudder angle indicator has the functions of real-time video image display in a steering engine room, temperature display and the ship direction display by an electronic compass.

Description

technical field [0001] The invention relates to a rudder angle indicator, in particular to a rudder angle indicator with video and electronic compass display. Background technique [0002] The rudder angle indicator is a very important instrument used to indicate the rotation direction and angle of the rudder blade when the ship is running, and it is usually installed directly in front of the rudder platform in the cockpit of the ship. According to the existing products, it can be divided into three types according to the display mode: pointer type, digital type and digital pointer type. [0003] Among the existing rudder angle indicators on the market, according to the angle sensor used by the transmitter, it can be further divided into ordinary carbon brush potentiometer type rudder angle indicators, inductive type rudder angle indicators, and self-adjusting machine type rudder angle indicators. device and digital coded rudder angle indicator, etc. [0004] 1) The induct...
