Traditional video surveillance is widely used in the power industry, including the deployment of video surveillance in unattended substations, safety production, and transmission lines. Among them, the monitoring application of unattended substations is particularly typical, with significant power system industry characteristics. Substations are the hub of the power grid and are also an important target for power safety management. Establishing a networked video surveillance system in unattended substations can help the power sector to effectively save human resources and improve safety management efficiency.
With the development of high-definition and security integrated technologies, this application is showing a clear trend of high-definition and security integration.
In deployment, each substation conducts planning and deployment of monitoring points according to the number of objects that need to be monitored and the functions that need to be completed. Each monitoring point is centered on a high-definition network camera. It is connected to alarm devices such as magnetic, infrared, smoke, and temperature sensing through corresponding interfaces, and connects audio devices such as pickups and loudspeakers through the audio input and output interfaces. HD network cameras are used to capture images of substation monitoring sites inside and outside, including gates, perimeters, computer rooms and substations. The access control system is deployed at the gate of the substation and can register internal employees' access. It can send an alarm signal when someone illegally invades. The smoke and temperature sensing devices mainly detect the internal environment temperature, smoke and dust, and prevent fires. In case of alarm, they can send alarm signals in time.
Infrared radiation alarms are mainly deployed in surrounding areas of substations. When someone climbs over the wall and enters the station, infrared alarms will be triggered.
These alarm devices are connected to the video encoder through alarm monitoring. When an alarm occurs, the linkage can be performed through the management platform. In the dispatch center, sound and light alarms, image switching, and recording control can be implemented.
The pickups and loudspeakers are audio intercom devices, which can be connected to monitoring systems through HD network cameras to implement voice intercoms between the dispatch center managers and substation field personnel, thus realizing remote scheduling of monitoring points by the dispatch center. At the same time, this function can also realize remote maintenance guidance for substation equipment, thereby shortening the time for solving problems and reducing manpower and cost. In addition, the monitoring and management platform can also be integrated with the existing substation power environment monitoring system. The environment monitoring system collects operational faults such as transformers, lines, switches, circuit breakers, and instrumentation as well as abnormal operating environments such as voltage, current, and temperature. Can trigger the video surveillance system linkage, in the dispatch center for sound and light alarm, image switching and video control.
As an intuitive, efficient, and timely remote communication tool, videoconferencing has become an important part of the information technology application of the power industry. It includes various types of video conference derivative applications such as remote consultation, remote training, and remote collaboration. The power company's management, training, collaboration, emergency and other aspects.
Convening various types of work conferences remotely through the Internet is a typical application of videoconferencing in the power industry. Based on this application, business leaders can communicate “face to face†with relevant heads of subsidiaries and branch offices without leaving home. Scenes running around will no longer appear. This will save time and costs for the organization of the meeting and improve the efficiency of communication and management.
Talents are the source of power for sustainable development of electric power companies. To improve overall competitiveness, it is necessary to constantly improve and perfect the talent training mechanism of enterprises.
Due to the large number of dispersed and disparate power company organizations, organizing large staff training is quite a headache for them. However, based on video conferencing, remote video training for hundreds of people and thousands of people can be easily organized. This not only helps companies significantly reduce training expenses, but also more importantly, increases training frequency and achieves more sharing.
All remote conference and training processes, as well as supporting materials such as meeting materials and training courseware, can be simultaneously broadcasted to the company's internal network. Employees can perform selective real-time viewing according to their own authority. Moreover, the above content can also be recorded synchronously through the recording and broadcasting functions of video conferences and posted on the Internet for on-demand learning by employees.
Integrating video surveillance into a visual emergency command and dispatch system not only does not affect the safety online warning and real-time monitoring functions of the original substations and transmission lines, but also seamlessly integrates these image, sound, alarm, and power environment information into the emergency command. The platform provides intuitive and real-time reference for command decisions and improves decision-making efficiency. At the same time, through visualizing the emergency command and dispatch system to integrate video conference applications, the two-way, multi-party, and real-time interactive visual application functions of video conferences can greatly strengthen the collective and collective forces of emergency command, and increase the speed of decision-making and management efficiency.
Of course, to truly visualize the effectiveness of emergency command and dispatch, it is not simply to combine videoconferencing and video surveillance. Instead, it is necessary to refer to the traditional voice dispatch service that the power industry has been using from the perspective of the emergency command management system. The model newly developed a professional visual emergency command business architecture and business system, and then integrated the resources of video surveillance and video conferencing on this basis. This is the real need of the power industry.
In this sense, a professional visual emergency command and dispatch system must focus on visual scheduling and emergency command, and at the same time realize the integration and integration of multiple services such as video conferencing, remote monitoring, and image transmission. Typical components include professional dispatching platforms, scheduling seats, video walls, video, network management, and various forms of dispatch terminals. The dispatch terminal is located at all remote points that can accept remote dispatch or remote command. The types include videoconferencing terminals, video monitoring terminals, telephones, and mobile phones. The video conference terminal is mainly located in the subordinate power unit that accepts command and dispatch or on the mobile command vehicle, and can perform two-way visual communication with the dispatch center. The video monitoring terminal is mainly located in substations, transmission lines and mobile command vehicles. It is used to provide scheduling access for on-site monitoring images. Telephones and mobile phones are used for personal voice-only scheduling access. These terminals can be new or integrated with legacy systems such as video conferencing and video surveillance.
Dispatching center, sub-distribution center or leading desktop can all perform unified scheduling and unified command for all the above remote resources. No matter whether it is point-to-point or point-to-multipoint, the remote image can be transmitted to the large screen or PC display of the dispatch center in an instant. On the equipment, there is no glance. During the scheduling process, professional command and dispatch functions such as strong insertion, forced release, hot-key call, call transfer, transfer, video playback, and single-messaging of short messages can be implemented. Considering the convenience of operation, all of the above operations can use the touch-sensitive dispatch screen, which allows one-touch calling or voice recognition to directly call the other party's name for easier scheduling based on a simple and intuitive interface.
From a typical application perspective, the entire visual emergency command system needs to provide at least the following business function modules:
1. The Video Point Name Dispatch Center can manually or automatically complete the name of each unit by the video point name function module. In the daily management work, the daily work preparation of each unit can be checked by the name function to ensure that the on-duty personnel are in place and that the equipment and circuits are operating normally, and that emergency treatment can be carried out promptly in the event of an emergency.
2. The preplanning dispatching system must be able to formulate types of contingency plans such as natural disasters, accidents, and public security incidents, and be able to formulate subcategories such as fire, earthquake, and theft. When the incident occurs, it is invoked through a preplan, and immediately calls the relevant departments to participate in the consultation or command and mobilize relevant image resources. The preplan function is to reserve a docking interface so as to enable linkage activation with the comprehensive emergency plan.
3. The fast dispatching system must support rapid querying and organization of dispatching resources. It can quickly mobilize related image resources when a temporary event occurs. Within a few seconds, the visual communication deployment of temporary command and dispatch can be completed. Fast scheduling ensures that the system can be used in any emergency situation.
4. Auxiliary video services As the system itself is to be integrated with videoconferencing and video surveillance, it is also widely used for the convening and control of videoconferencing and video surveillance directly on the dispatching center based on the dispatching platform.
5. The video recording and broadcasting system needs to integrate professional video recording and broadcasting modules to complete applications such as daily image storage and scheduling process video recording, and to save and recall large-capacity, highly reliable video data through professional disk arrays.
Conclusion: With the development of wireless broadband technology, the application of mobile video integration in the power industry is also increasingly widespread. By visualizing the emergency command system and accessing the mobile video to the dispatch center, it can effectively improve the on-site emergency response capability and emergency treatment efficiency, and minimize disaster losses. The deployment of on-site mobile video can use mobile communication vehicles, personnel piggyback, etc. Whether it is the vehicle or the individual soldier, the accident scene image and sound can be uploaded to the command and dispatch center in real time based on the 3G or satellite network. The command and dispatch center can also communicate with the on-site personnel in real time, and perform remote command and guidance to the on-site personnel.
In recent years, under the background of strengthening the emergency management system for power systems, both the traditional video surveillance and traditional video conferencing have begun to become more diversified in their application modes, and these video applications are integrated based on visualized emergency command and dispatch. On a unified platform, it is becoming a new trend in the power industry. This trend will play a positive role in transforming the current emergency management of the power system, further improving the efficiency of emergency management, and reducing the cost of emergency management.
