Abstract
Description
Technical Field
[0001] The invention relates to a nuclear power two-color alarm lamp with adaptive signals, which is specifically used in daily broadcasting and emergency response and belongs to the field of safety monitoring lighting in high-noise areas of nuclear power plants. Background Art
[0002] Nuclear power plants are important national energy supply facilities. In order to ensure the safe operation of nuclear power plants, a series of safety measures need to be taken. As one of the important safety equipment, the performance and quality of nuclear power plant alarm lights are directly related to the safety performance of nuclear power plants.
[0003] There are many machines and equipment inside a nuclear power plant, which will generate a lot of noise when running. In order to make the warning lights of nuclear power plants work effectively in high-noise environments and ensure that they can quickly attract the attention of personnel in an emergency. In response to high-noise environments, warning lights of nuclear power plants usually use high-brightness LED light sources, combined with sound alarms, to form a dual warning effect of vision and hearing to ensure the safe operation of nuclear power plants. Therefore, the warning lights of nuclear power plants should have the following characteristics: high brightness to ensure clear visibility when the field of vision is obstructed, high reliability and stability to adapt to harsh industrial environments, and integration and intelligence to enable remote monitoring and control.
[0004] At present, commonly used nuclear power plant alarm lights include sound and light combination alarm lights, radiation alarm lights, fire alarm lights and leakage alarm lights. Among them, the sound and light combination alarm lights can effectively combine the two alarm methods of sound and light, while the radiation alarm lights are generally used in high-risk areas to ensure that the staff can take protective measures in time. However, most nuclear power plant alarm lights are monochrome lights. Monochrome nuclear power plant alarm lights are important equipment used in the nuclear power field to indicate and warn of equipment status or system abnormalities, but they can only be used for emergency alarms or indicator lights. They cannot simultaneously meet the needs of being used as indicator lights during daily broadcasts and as emergency alarms in emergency situations. It is necessary to set up a variety of alarm lights in the nuclear power plant area, which is easy to increase costs and waste space. Summary of the invention
[0005] In view of the above problems, the purpose of the present invention is to provide a nuclear power two-color alarm light with adaptive signals, which adopts relay control to realize different flashing modes of the nuclear power plant alarm light in daily broadcasts and emergency situations of the nuclear power plant, so as to meet the needs of routine calls and emergency situations of the nuclear power plant.

[0013] Furthermore, the first relay and the second relay are dry contact relays.
[0014] Furthermore, the yellow warning light and the red warning light are LED indicator lights.
