Description

Technical Field

[0001] The present invention belongs to the technical field of risk area management systems, and in particular relates to a risk area operator management system and method applicable to a hydropower station. Background Art

[0002] Hydropower station production sites present numerous risk areas, such as wind tunnels, turbine volutes during maintenance, and waterwheel chambers. These operating environments share common characteristics, requiring high levels of personnel control and management. For example, during maintenance, other work may threaten the safety of personnel working in the turbine volutes and waterwheel chambers. For example, moving guide vanes could cause workers in the turbine volutes and waterwheel chambers to be pinched by the vanes. Remotely measuring rotor insulation in wind tunnels requires applying a corresponding measurement voltage to the stator and rotor, potentially causing electric shock to personnel in the wind tunnel. Furthermore, when operating in wind tunnels and waterwheel chambers during shutdown, in the event of an emergency restart, personnel must be notified to evacuate within three minutes.

[0003] To meet these management requirements, the current approach is to manually register personnel at entrances and exits, and to have personnel enter the wind tunnel or waterwheel room to make evacuation confirmations before shaking the insulation or moving the guide vanes. This practice not only wastes human resources but also requires personnel to be on duty at the entrance and exit booths at all times. Furthermore, due to the complex working environment and ambient noise, personnel entering to make evacuation confirmations may not be able to find the operating personnel, or the operating personnel may not receive or miss evacuation information, resulting in personal injury. Summary of the Invention

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0030] like Figure 1 As shown, the risk area operator management system applicable to a hydropower station of this embodiment includes a data processing and analysis module 1, an audible and visual alarm control module 2, an access control management system 3, and a power station image monitoring system 4. The audible and visual alarm control module 2, the access control management system 3, and the power station image monitoring system 4 are electrically connected to the data processing and analysis module 1 respectively;

[0031] The data processing and analysis module 1 is used to:

[0032] Process and analyze the access control verification information collected in the access control management system 3;

[0033] When it is necessary to notify the relevant area personnel to evacuate, the power station image monitoring system 4 is controlled to call the monitoring camera 7 of this area and receive the video stream transmitted by the power station image monitoring system 4;

[0034] Control the sound and light alarm control module 2 to start the sound and light alarm device 6 in the corresponding area.

[0035] The present invention utilizes the access control management system 3 that has been put into operation at the hydropower station, and sets up access control card swiping or face recognition devices on both sides of the entrance and exit of the risk area that needs to be managed. That is, identification and registration are required for entry, and identification and registration are also required for exit. At the same time, the entry and exit time are automatically recorded in the system. Sound and light alarm devices 6 are installed in the wind tunnel, waterwheel room, and volute outlet. If it is necessary to carry out work that affects the safety of the working environment, such as moving guide vanes, measuring rotor insulation, etc., or in case of emergency startup to notify operators to evacuate urgently. The management system automatically starts the sound and light alarm, and the power station image monitoring system 4 automatically calls the camera 7 in this area to display the picture of this area. At the same time, the management system will automatically determine whether there are people working in this area based on the access control registration data. The present invention can improve the management efficiency of operators in risk areas, save human resources, and improve the safety level of operators.

[0036] The access control system 3 is electrically connected to a number of access control devices 5 installed at the entrances and exits of risk areas. The access control devices 5 register the entry and exit personnel and the time.

[0037] The sound and light alarm control module 2 is electrically connected to a plurality of alarm devices 6 , which are installed in risk areas.

[0038] The power station image monitoring system 4 is electrically connected to a plurality of cameras 7 , which are installed in the operation area.

[0039] like Figure 2 As shown, the method for managing personnel in risky areas of a hydropower station according to this embodiment includes the following steps:

[0040] S1: During actual operation, when an operator needs to enter or leave a risk area, the access control management system 3 collects access control verification information and sends it to the data processing and analysis module 1;

[0041] S2: When it is necessary to notify personnel in relevant areas to evacuate, the data processing and analysis module 1 screens the personnel who have registered to enter the risk area and notifies them to evacuate, controls the power station image monitoring system 4 as an auxiliary criterion for whether there are operating personnel, and controls the sound and light alarm control module 2 to sound an alarm.

[0042] In step S1, the operator enters the risk area by swiping the access card or using facial recognition; the access control management system 3 transmits the personnel information to the data processing and analysis module 1; the data processing and analysis module 1 automatically registers the personnel information and entry time.

[0043] In step S1, the operator leaves the risk area by swiping the access card or using facial recognition; the access control management system 3 transmits the personnel information to the data processing and analysis module 1; the data processing and analysis module 1 automatically updates the personnel departure information and departure time.

[0044] In step S2, when an emergency or special operation occurs and people in the risk area need to evacuate automatically, the data processing and analysis module 1 selects the evacuation area, automatically screens people in the area who have not registered to leave, makes phone and text message notifications, and cyclically screens every 2 minutes until all people have registered to leave.

[0045] In step S2, the data processing and analysis module 1 activates the sound and light alarm device 6 in the corresponding area, starts the sound and light alarm and keeps it on for 5 minutes; the data processing and analysis module 1 controls the power station image monitoring system 4 to call the monitoring camera 7 in the corresponding area, and displays the real-time monitoring picture of the corresponding area as an auxiliary criterion for determining whether there are operating personnel.

[0046] Working principle:

[0047] During actual operation, when a worker needs to enter a risky area, they enter by swiping their access card or using facial recognition. Access control management system 3 transmits the worker's information to data processing and analysis module 1, which automatically registers the worker's information and entry time. When a worker leaves the area, they also swipe their access card or use facial recognition. Access control management system 3 transmits the worker's information to data processing and analysis module 1, which automatically updates the worker's departure information and time.

[0048] When an emergency or special operation occurs, personnel in a certain area need to evacuate automatically. By selecting the evacuation area in the risk area operator management system, the system will automatically screen out personnel in the area who have not registered to leave, and notify them by phone and text message, and will cycle through the screening every 2 minutes until all personnel have registered to leave. At the same time, the sound and light alarm device 6 in the corresponding area is activated, and the sound and light alarm is activated and lasts for 5 minutes. In addition, the power station image monitoring system 4 is controlled to call the monitoring camera 7 in this area to display the real-time monitoring screen of the area as an auxiliary criterion for determining whether there are operating personnel. Its business process is as follows Figure 2 shown.

[0049] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
