With the continuous development of the economy, the demand for energy power is also constantly increasing, so the demand for energy power industry security is also increasing. Moreover, traditional human resources management is no longer able to adapt to the trend of intelligence and digitization in energy power applications. Intelligent security systems have been widely applied in the energy power industry, continuously improving the safety and protection performance of the energy power industry.

1 Energy power industry security and anti-theft requirements

The energy power industry is a very important industry, closely related to our society and daily life. Undoubtedly, the energy power industry generally needs to improve security performance and intelligence. According to the investigation, the current maintenance, management, and anti-theft situation of energy power facilities are summarized as follows:

• Most energy power facilities such as transformers are located outdoors and scattered in cities, suburban areas, rural areas, etc., which brings a lot of trouble to the safety management of transformers.
• It is impossible for energy power enterprises enterprises to allocate a large amount of manpower to monitor each transformer in real time to prevent equipment from being stolen or destroyed.
• The energy power industry has also used methods such as infrared, wireless communication, and physical anti-theft methods to solve the anti-theft problem of transformers. However, due to the limitations of these systems or product principles, false alarms, and weak anti-interference ability, they cannot receive alarm signals in a timely manner, resulting in a significant waste of manpower, material resources, and financial resources. At the same time, wireless communication methods have high power consumption (energy consumption) and require permission from relevant government departments, which also has certain limitations on the promotion of systems and products.

In summary, incidents of theft of energy power wires and transformers are quite serious, and relevant departments attach great importance to them. Human and technological prevention are the most effective methods. According to the actual situation, relevant units can install energy power security systems.

The energy power security system is mainly used for anti-theft of power wires and transformers. Its characteristics are: not limited by distance, not limited by quantity, not affected by climate, and can only have one alarm monitoring center. The computer is equipped with alarm software, which can display the actual location of the alarm transformer and fault wire in electronic map, and record the alarm response time in real time. After connecting the computer to the printer, information such as data, alarm date, time, and extension number can be printed for future reference, reducing investment costs. This system has the characteristics of practicality, excellent quality, stable and reliable operation, and is suitable for various outdoor environments. It is widely used in the safety protection of all energy power industries working outdoors, such as electricity, oil, and mining, etc. It is currently a relatively advanced safety prevention system.

2 The composition and characteristics of the energy power industry security system

The energy power industry security system consists of a GSM wireless anti-theft alarm receiving control panel, a computer (alarm software), and several monitoring station wireless alarm control panels to form an anti-theft alarm system. Several wireless monitoring and alarm control panels are installed on the poles or transformers of the monitored power lines. Once the power lines or transformers are stolen, three-phase disconnection or power outage occurs, the monitoring wireless alarm control panel immediately detects and sends an alarm signal to the GSM wireless anti-theft alarm receiving control panel through wireless GSM short messages and voice. After receiving the alarm signal, the GSM wireless anti-theft alarm receiving control panel transmits the data to the computer. After analyzing and judging the alarm control panel and the possible faulty circuit through the alarm software, the computer issues an alarm. The computer monitor displays the alarm date, time, alarm extension number, faulty transformer and possible faulty circuit, and displays the actual location of the alarm transformer and faulty circuit in electronic map. The alarm data is stored in the database for future reference. After receiving the alarm information, the on duty personnel immediately dispatched security persons to the scene to inspect the situation and handle relevant issues.

Compared with traditional transformer anti-theft wireless alarm systems, this system has the following characteristics:

(1) Superiority

• The coverage area is wide, and currently the mobile communication network has a coverage rate of over 95%.
• The communication distance is long, and an alarm monitoring center can be set up in any situation.
• High network reliability.
• Good stability, on the one hand, strong ability to resist natural interference. On the other hand, the frequency band is dedicated and will not be subject to human interference.
• There is no need to negotiate with the radio management department, nor is there a need to pay radio management fees (within GSM / GPRS coverage).
• Low communication costs.

(2) Real time and security

• Equipped with self-checking function. It can occasionally check whether the device is operating normally.
• Transformer three-phase disconnection alarm function.
• If there are other alarm signals, they can also be transmitted. When an abnormal situation occurs, the system issues an alarm and can notify the alarm monitoring center of the type, time, and location of the accident, truly achieving real-time alarm.

(3) Maintainability

• The alarm software has a self diagnostic function. If there is a fault on the remote terminal, it will be automatically diagnosed by the computer of the alarm monitoring center.
• The failure of the remote terminal will not affect the operation of the entire system.

3 New technologies for the energy power industry security system

(1) 3G and 4G network transmission. With the application and development of 3G and 4G technologies, various industries have applied 3G and 4G technologies extensively, making it easier to achieve network functions and solve network application problems. The use of 3G and 4G network transmission has solved the network problems encountered in installing security systems in remote power base stations, substations, power towers, and other places, promoting the development in the energy power industry security applications.

(2) High definition technology. Driven by the trend of networked monitoring and market demand, high-definition monitoring technology has made significant breakthroughs and entered practical applications in major security projects. With the continuous expansion of energy power monitoring demand and power network bandwidth, high-definition monitoring systems will accelerate the seamless integration of energy power monitoring systems with other security subsystems, and further promote the seamless integration of security systems with business management systems. This also brings broader development space for high-definition video monitoring.

(3) Intelligent behavior analysis technology. The application of video intelligent behavior analysis technology can achieve pre warning, in-process processing, and post evidence collection, while also improving the functionality of video detection. Such as smoke and fire detection, perimeter intrusion detection, movement detection, abandoned object detection, illegal stay detection, wandering person detection, automatic tracking and alarm of detected targets, achieving humanized and intelligent monitoring. These are constantly developing in the energy power industry, as well as in the application of unmanned substations.

4 The development direction of the energy power industry security system

The energy power industry security system is developing towards a highly integrated comprehensive monitoring direction that integrates front-end image monitoring systems, environmental monitoring systems, anti-theft alarm systems, and fire protection systems. Thereby improving the safety and convenience of personnel and equipment by ensuring that there are no or fewer people on duty.

In order to strengthen the comprehensive management level of safety production, anti-theft alarm, fire alarm and other aspects of substations and unmanned substations, and achieve the goal of becoming first-class, more and more energy power enterprises are considering building centralized remote video monitoring systems to promote the networked development of comprehensive power monitoring. Through IP digital video, it is possible to monitor the relevant data, environmental parameters, and live videos of each substation, understand and grasp the situation of each substation in real time and directly, and respond to the situation in a timely manner to meet the needs of safety management in the energy power industry.

The demand and function in the energy and power industry security system are constantly improving and enhancing with the development of information technology. The application of integrated, digital, high-definition, and intelligent new products and technologies will be the direction of its development, which will elevate the security and prevention technology of the energy power industry to a new level.
