Full-digitalization underwater lamp dimming device

Abstract

The invention discloses a full-digitalization underwater lamp dimming device comprising a singlechip, a communication bus module, a photoelectric isolation circuit module and a main circuit module, wherein the singlechip serves as the core and receives the digital control signal of a main control computer by the communication bus module; the control signal triggers the silicon controlled rectifier (SCR) of the main circuit module to conduct by isolating a triggering circuit module after processed by the singlechip; the singlechip collects the digital interrupt signal of a main power input module by an isolation synchronizing circuit module to serve as the synchronizing signal triggered by the SCR; the SCR of the main circuit module regulates the voltage of the underwater lamp by the received trigger signal; the main power input module is connected with the singlechip by an AC / DC converter module for supplying power; and the main power input module supplies power to the underwater lamp by the main control circuit module. The device saves weight and space, causes the interface of the dimming device to be simple, and has simple adjustment, high reliability, low cost and powerful function.

Description

technical field [0001] The present invention relates to the dimming technology of underwater lights of underwater robots, specifically a fully digitalized underwater light dimming technology that uses digital control technology and communication technology to distribute control of underwater lights and realize digital and modular control of underwater lights. Light device. technical background [0002] An underwater robot is a device that works in the sea. There are multiple underwater cameras installed on it. To observe the situation in the sea, the cameras need underwater lights to provide lighting. Due to different sea areas and seasons, the visibility in sea water Different, moreover, as the distance of the camera is different from the object to be observed, the clarity of the image is also different, so the brightness of the lights required by the camera at different positions on the underwater robot is also different. There are usually two ways to adjust the brightnes...

Problems solved by technology

There are usually two ways to adjust the brightness of the underwater lights on the conventional underwater robot. The first method uses an adjustable voltage transformer on the water surface to change the voltage. The disadvantages of this method are: 1. If the voltage is changed, all underwater The lights on the underwater robot are all changed, which leads to changes in the lighting of other cameras that have been adjusted, resulting in poor video effects of the observed target; Second, due to the very long transmission distance from the water surface to the underwater robot carrier, The resistance is very large and consumes a lot of power. In this sense, it is also a bottle diameter for deep underwater robots.

The second method uses the dimming device in the electronic cabin to centrally adjust the dimming device by the computer in the cabin. Although the individual dimming of each lamp can be realized, this solution not only takes up a lot of space in the electronic cabin, but also Expansion is also difficult to realize. It is necessary to adjust the layout of the electronic cabin or redesign the electronic cabin, which not only increases the cost and time, but also makes the number of connectors in the electronic cabin very large, so that the volume of the electronic cabin becomes larger , the chance of failure also increases

Therefore, the above two dimming methods are increasingly unsuitable for the development of underwater robots.
