Intelligent digital networked infrared probe for track train fault detection

Abstract

The invention discloses an intelligent digital networked infrared probe for track train fault detection. Due to the standard design based on an OSI model, probe networking is achieved; a data cloud center can directly operate target probe data, data tracking, recognizing and specific fault removal of the specific train can be achieved. Infrared probe intelligentization is achieved, the gain can beintelligent regulated, and under the specific condition, zero calibration, target calibration, self-detection, temperature actual measurement and other operations can be performed without depending on an upper computer; the probe data collecting storage function is achieved, data storage under various fault modes of probe upper computer passage faults, upper computer faults, upper computer collection software faults and the like can be performed, the system all-weather operation reliability is improved, and the track train fault infrared detecting system is simplified.

Description

technical field [0001] The invention belongs to the field of railway safety monitoring, and in particular relates to an intelligent digital networked infrared probe for rail train fault detection. technical background [0002] Temperature has become an important parameter in industrial production, and it is also an important indicator to characterize the operation status of equipment. When equipment has mechanical failures, electrical failures and other failures, an obvious feature is abnormal temperature. At the same time, abnormal temperature is also an important factor causing associated equipment failure. Therefore, the temperature is closely related to the operating state of the equipment, and temperature detection plays an important role in the technical system of equipment operation fault monitoring. Use contact or non-contact temperature measurement technology to detect the temperature or temperature distribution of operating equipment components, and then analyze t...

Problems solved by technology

[0005] The current THDS system uses analog signal transmission. Due to the complex electromagnetic environment at the trackside, the analog signal is susceptible to interference, and the signal-to-noise ratio will be lost after the analog signal is transmitted over a long distance.

Because both the probe and the probe box use an analog system to transmit signals and control signals, multiple cables are required for transmission, which increases the difficulty of construction, wastes cable resources, and increases the potential failure rate of the system

[0006] The current infrared probe can only complete the work at the sensor level. Zero calibration, calibration, and back-end signal processing all need to be completed by the host computer, and the gain of other probes is fixed and cannot be adjusted.

At the same time, once the communication failure or the host computer failure, the probe data cannot be stored, and failure detection may occur
