Description

Technical Field

[0001] The invention relates to the field of safety monitoring of nuclear power high noise areas, and in particular to a two-color warning lamp for nuclear power high noise areas. Background Art

[0002] In nuclear power plants, there are areas with high noise levels due to equipment operation, steam flow, etc. The noise level in these areas may exceed the safe hearing standard, which may damage the hearing of workers, so hearing protection equipment is required when entering these areas. In such a high-noise environment, the role of alarm indicators is particularly important. Due to excessive noise, workers may not be able to hear traditional audible alarm signals. Alarm indicators use visual signals to alert workers to emergency situations or abnormalities in operations, ensuring that they can respond in time to ensure safe production and personal safety.

[0003] Most of the existing alarm indicator lights are monochrome alarm indicator lights, but such alarm indicator lights may have problems that need to be improved or solved in certain environments and applications: 1. Limited information transmission: Single-color alarm indicators can only transmit a single type of information, such as red for danger or warning. This single signal transmission method cannot distinguish between alarms of different types or urgency, resulting in unclear and inadequate information transmission.

[0004] 2. Lack of priority distinction: The single-color alarm indicator light cannot effectively distinguish the priorities of different alarms, making it difficult to highlight emergency situations, making it difficult for staff to quickly identify and respond to the most important alarms when handling alarms. Summary of the invention

[0005] In view of the problem that the emergency alarm indicator light in the high noise area of ​​the above-mentioned nuclear power plant has only one color during alarm operation and cannot distinguish the alarm level, the purpose of the present invention is to provide a two-color alarm light for a high noise area of ​​a nuclear power plant. The device is connected to the two-color alarm light and can distinguish between ordinary broadcasts and emergency alarms. When a business broadcast is issued, the alarm light in the corresponding area lights up yellow, and when an emergency broadcast is issued, the alarm light in the corresponding area lights up red.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A nuclear power high noise area two-color alarm light, comprising: an alarm control board, a two-color alarm light and a speaker; The alarm control board is used to receive daily broadcast signals or emergency alarm signals sent by the superior control station, and generate corresponding control signals to the two-color alarm light and speaker; The dual-color warning light and the loudspeaker give prompts with lights of different colors and perform audio broadcasts at the same time according to the received control signal.

[0007] Furthermore, the alarm control board is provided with a signal input module, a switching module, an output module, a display module and a power conversion module; The power conversion module is used to convert 220V AC power into 24V DC power to power the alarm control board; The signal input module is used to access daily broadcast signals and emergency alarm signals; The switching module is used to switch the circuit according to the daily broadcast signal and the emergency alarm signal received, and control the dual-color alarm light and the speaker through the output module; The display module is used to display the input and output status of the alarm control board.

[0008] Furthermore, the signal input module adopts an 8HEADER connector, and pins 3 and 4 of the 8HEADER connector are used as input terminals for daily broadcast signals, pins 7 and 8 are used as input terminals for emergency alarm signals, and the remaining pins are reserved; The switching module includes a first relay and a second relay, and when an emergency alarm signal is generated, the 7th and 8th pin inputs in the 8HEADER connector are short-circuited, the first relay is turned on, and the switch is pulled down to output the emergency control signal to the red alarm light and the speaker through the output module; when a daily broadcast signal is generated, the 3rd and 4th pin inputs in the 8HEADER connector are short-circuited, the second relay is turned on, and the switch is pulled down to output the daily control signal to the yellow alarm light and the speaker through the output module.

[0009] Furthermore, the first relay and the second relay are dry contact relays.

[0010] Furthermore, the yellow warning light and the red warning light are LED indicator lights.

[0011] Furthermore, the alarm control board is arranged in an on-site junction box, which is connected to the dual-color alarm light and the loudspeaker through an alarm light junction box and a broadcast junction box.

[0012] The present invention adopts the above technical solution, which has the following advantages: 1. More accurate information transmission: The present invention utilizes a combination of red and yellow to represent alarms of different types or urgency levels, thereby helping staff to understand and respond to alarm information more accurately.

[0013] 2. Priority distinction: The dual-color alarm indicator can distinguish the priority of the alarm through different color combinations or flashing frequencies. For example, continuous red indicates a high emergency, and flashing yellow indicates a moderate warning, which helps staff quickly identify and respond to the most important alarms.

[0014] The present invention can greatly improve the reliability and effectiveness of the alarm system in the high noise area of ​​nuclear power plants by introducing a new dual-color alarm indicator technology, thereby ensuring the safety of workers and the smooth operation of nuclear power plants. Therefore, the present invention can be widely used in the field of safety monitoring in high noise areas of nuclear power plants. BRIEF DESCRIPTION OF THE DRAWINGS
