Intelligent monitoring system for ski jumping assistant slideway

Abstract

The invention discloses an intelligent monitoring system for a ski jumping assistant slideway. The system comprises a temperature monitoring system and a flatness detection system, a hardware part of the temperature monitoring system comprises a fiber bragg grating temperature sensing array and a fiber bragg grating demodulator, the fiber bragg grating temperature sensing array is formed by connecting 30 fiber bragg grating temperature sensors in series and is arranged on an assistant slideway, and the whole ski jumping assistant slideway needs four temperature sensing arrays; the flatness detection system comprises wireless tilt angle sensor groups, a Lora wireless gateway and a wireless data transmission device; the number of the wireless tilt angle sensor groups is 12, the wireless tilt angle sensor groups are arranged on six spans of a ski jumping assistant slideway respectively, each wireless tilt angle sensor group comprises four wireless tilt angle sensors, and the total 48 tilt angle sensors are arranged on the assistant slideway. The fiber bragg grating demodulator and the wireless data transmission device are in communication connection with a data receiving server, the data receiving server is in communication connection with a software platform server, information transmission is stable, measurement precision is high, and measurement results are accurate.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring of a ski jumping aid track, in particular to an intelligent monitoring system for a ski jumping aid track. Background technique [0002] Whether ski jumpers can achieve good results is not only influenced by their own performance level, but also has a lot to do with the geometry and surface smoothness of the ski jumping chute. It can be seen from the development status of ski jumping at home and abroad that the construction and maintenance of ski jumping slides are in a relatively rough stage. [0003] The temperature monitoring of the pavement layer in the chute of the ski jumping aid chute has no special equipment and technology for this purpose at home and abroad. Drawing on the existing technical means of temperature monitoring, laser temperature measurement is time-consuming and laborious, and its accuracy is also low. It cannot be guaranteed; the measurement accuracy and dura...
