With the continuous development of the economy, the demand for electricity is also increasing. Therefore, the security status of the power is also rising. However, the traditional manpower management has been unable to adapt to the intelligent and digital trend of power applications. Intelligent security products have been widely used in the electric power field, continuously improving the security performance in the electric power field, and creating energy and value for society and life.
Power system security anti-theft intelligence needs
Electricity is a very important industry and it is closely related to our society and life. There is no doubt that the power industry generally needs to improve security performance and intelligence. According to the survey, the current status of maintenance, management and anti-theft of power facilities is summarized as follows:
â— Most of the power facilities such as transformers are outdoors and are scattered across streets, urban and rural areas, and rural areas, which has caused a lot of trouble for transformer safety management.
â— It is impossible for the power sector to allocate a large amount of manpower to conduct real-time monitoring of individual transformers in an artificial manner to prevent equipment theft or destruction.
â— In China, some provinces and cities have also used such methods as infrared, limited-distance wireless communication, and physical anti-theft cards to solve the anti-theft problem of transformers. However, due to the limitations of these system or product principles, false alarms, and weak anti-interference ability, they cannot receive alarm signals in time, resulting in a large amount of wasted human, material, and financial resources. At the same time, the wireless transmission method has a large power (consuming energy) and requires the approval of related departments, and there are also certain restrictions on the promotion of the system and products.
In summary, the theft of power lines and transformers is serious, and the relevant state departments attach great importance to it. Air defense and technical protection are the most effective measures. For the actual situation, relevant units can install power transformer intelligent anti-theft system. This system is mainly used for power line and transformer anti-theft alarm, its characteristics are: not limited by distance, not limited by quantity, not affected by the climate, you can set up only one alarm center. The microcomputer is equipped with the alarm center software, which can display the actual location of the alarm transformer and the faulty line by electronic map, and record the alarm time in real time. After the printer is connected, the data, alarm date, time, and extension number can be printed for future reference to reduce the investment cost. The system is functional, practical, of high quality, stable and reliable, and suitable for outdoor use in various environments. It is widely used in electric power, petroleum, mining and other electric equipment for outdoor protection. It is currently the most advanced of its kind in the country. Security system.
Composition and characteristics of power anti-theft alarm system
The power alarm system consists of a GSM wireless anti-theft alarm receiver host, a microcomputer (the alarm software) and a number of monitoring station alarm host to form a burglar alarm system. Several wireless monitoring and control mainframes are installed on the poles or transformers of the monitored power lines. Once the power lines or transformers are stolen, three-phase disconnected or power failure, the monitoring and alarming host immediately detects and receives GSM messages and voices to GSM. Host alarm, the receiving host receives the alarm signal and transmits the data to the microcomputer. The microcomputer analyzes and judges the alarm host and possible faulty line after the host receives the alarm. The screen displays the alarm date, time, alarm extension number, faulty transformer and possible Fault lines, and the actual locations of alarm transformers and faulty lines are displayed on an electronic map, and alarm data is stored in the database for reference. Immediately after receiving the alarm, the on-duty leader sent the police to the scene to check the situation and handle the relevant issues.
1, the characteristics of power anti-theft alarm system:
â— GSM Chinese SMS alarm, intuitive and reliable, unlimited transmission distance.
â— Eight wired zones, self-programming select normally open / normally closed contact alarm mode. The alarm contact adopts opto-isolated input to prevent external strong electricity and lightning from destroying. When the alarm is restored, it actively reports the status of the defense zone to a remote location.
â— Three short messages and three voice dialing alarm numbers. You can use an ordinary mobile phone to manually receive an alarm, and you can also use the PH-BC110 alarm center computer to automatically receive an alarm. Electronic map map display, with powerful networking alarm function.
â— With boot report sending and remote inspection functions (test report and test information sent at regular intervals), it is possible to find out whether the alarm host is working properly.
â— Three-phase detection can accurately detect and report any abnormal condition of one phase.
â— Each zone uses Chinese alarm information, users can change the alarm information content.
â— Built-in 12V standby rechargeable lithium battery, automatic charge and discharge control, automatic switching after power failure, can be continued for 24 hours.
â— The host installation address can be edited, and the alarm personnel can know the specific alarm location.
2. Compared with the traditional transformer anti-theft wireless alarm system, this system has the following features:
â— Comparability 1. Covering a wide area, the coverage rate of the current mobile communication network in the country is above 95%, and coverage in non-outlying areas is almost 100%. 2. The communication distance is far, and the central station can be set in any occasion. 3. The network has high reliability. 4. The stability is good, on the one hand the ability to resist natural disturbances is strong; on the other hand, the frequency band is dedicated and will not be subject to human interference. 5. No need to negotiate with the radio management department, do not need to pay radio management fees and ultra long-distance communication (within GSM/GPRS coverage). 6. In terms of cost, you can calculate the cost of a transformer for one year. That is, each text message charges 0.10 yuan, and the 50 text message fee is expected to last for one year.
â— Real-time and security 1. Self-checking function 2. Three-phase transformer disconnection alarm function. 3. If there are other alarm signals can also be transmitted. When an abnormal situation occurs, the system issues an alarm. The system can notify the monitoring and control center of the type, time, and location of the accident. It can truly alarm and alert people.
â— Maintainability The system software has a self-diagnostic function. If there is a fault on the remote terminal, it will be automatically diagnosed by the monitoring and control center monitoring computer. Failure of the remote terminal will not affect the operation of the entire system.
