The transmission line is an important part of the power system, and the inspection management of the transmission line is a basic work to effectively ensure the safety of the transmission line and its equipment. The system adopts the client/server network structure, which is composed of the handset and the background manager. It integrates the computers, the network communication and the embedded technologies. It has obvious advantages in the realization principle, the reliability, the practicability and the expansibility. The practical application shows that the system can effectively meet the requirements of the fast, efficient and timely inspection work. By changing the traditional inspection working mode, we actively explore the new ideas and the new modes of the line inspection management to minimize the missed and mistaken detection, and ensure the long-term, efficient and stable operation of the power lines.

Smart cars are widely used in various industries, and their operating status is crucial to the production safety of the industry. In this paper, a set of intelligent car control system is designed based on STM32F103C8T6 microcontroller, and the automatic control of the car is studied. The study selects a black rectangular field with white borders around it as the external environment for the car to run. Under the premise of ensuring that the car does not cross the boundary, the car can automatically cruise in the area and avoid obstacles when it encounters them. Firstly, establish the design idea of the control system and complete the construction of the car model; Secondly, design the overall scheme of the hardware system and program; Then use the oscilloscope to collect and verify the motor pulse signals and sensor output signals of the car under various working conditions; Finally, while maintaining a certain speed of the car, several real-vehicle verifications were carried out on the obstacle avoidance and sideline detection of the car. The results show that the car can well complete functions such as forward, backward, speed regulation, and obstacle avoidance. The automatic control system runs stably and has high reliability.
