Description

A Power Line Tower Monitoring System Based on Wireless Sensor Network

technical field

The utility model relates to the field of power line tower monitoring, in particular to the field of a power line tower monitoring system based on a wireless sensor network.

Background technique

Electric power facilities are the carriers of electric energy production, transmission and supply, among which high-voltage lines and power towers are the key facilities for remote electric energy transmission. both. The interruption of power transmission not only affects the normal life of human beings and causes economic losses, but also may affect the command and decision-making of disaster relief in the event of a disaster. It can be seen that the protection of power facilities is very important. However, due to the different environments and locations of high-voltage lines and power towers, and regional differences, if conventional inspection methods are used, the inspection cycle will be long, and hidden dangers cannot be found in the first place. At the same time, due to the limitations of various technologies and conditions, real-time information on power towers and lines cannot be transmitted to the control center in real time, which makes it necessary to establish a wireless real-time monitoring system for power towers.

At present, the parameter information monitoring of power facilities, especially the field backbone network transmission facilities including power towers, mainly adopts the above-mentioned manual inspection method and the drone inspection method carried out by power grid companies in pilot applications in the past two years. The cost of manual inspection is low, but the accuracy of the inspection result is low, the labor intensity is high, and it is easy to have inspection blind spots due to the limitation of the terrain because of the inability to reach manually; the helicopter inspection is easily affected by the weather, and the cost is very high, so the application Less, currently mainly in the pilot construction stage, only used in some disaster emergency response.

These two inspection methods have relatively large limitations, and with the emergence and rapid development of wireless sensor network technology, it is possible to apply it as a monitoring technology for power facilities. Compared with other technologies, it has two advantages: one is that it does not require cables, and the traditional wired monitoring network has huge wiring layout and implementation projects, and the wiring is easily damaged, immovable, and poorly adjustable. However, the terrain and location of the power tower are inconvenient and the area is large, so the wireless monitoring method is very suitable for the construction of this type of monitoring system. The second is the low energy consumption of wireless sensor networks. Due to the transmission and safety requirements of power facilities, high-voltage lines and power towers do not allow external equipment to directly take power from the power lines. The low energy consumption characteristics of wireless sensor networks using battery power solve this problem well. Therefore, domestic and foreign experts and scholars began to study how to apply wireless sensor network to the monitoring system of power facilities.

Both the detection module and the wireless gateway module are controlled by a single-chip microcomputer; the information collection module can simultaneously collect temperature, humidity data and video image information. At the same time, the wireless module communicates with the main processor through the UART asynchronous serial port and uses the SPI bus interface to complete the initialization and commands of the module.

The transmission power of this type of infinite module can ensure the reliability of signal transmission within the distance between power poles and towers.

Preferably, in a power line tower monitoring system based on a wireless sensor network, when the wireless gateways of the front and rear towers form a relay link, the linear separation distance is less than 3 kilometers from the effective transmission distance of the wireless module. This distance is the reliable working radius for the communication between the wireless module and the GPRS module, which ensures smooth communication after networking.
