Wireless temperature measuring system and measuring method of rotary device

Abstract

The invention provides a wireless temperature measuring system and a measuring method of a rotary device and belongs to the field of industrial automation. The measuring system and the measuring method solve the problems that according to an existing temperature measuring system and method, a conductive sliding ring is high in manufacturing cost and prone to abrasion and measurement precision is influenced. The measuring method includes the steps that a wireless power supply sending circuit converts electric energy supplied by a direct-current power supply into electromagnetic energy; a wireless power supply receiving circuit receives the electromagnetic energy in a wireless transmission mode and converts the electromagnetic energy into electric energy; a testing computer sends a temperature acquisition instruction to a second wireless signal receiving and sending circuit; a temperature measuring circuit receives temperature information, acquired by a temperature sensor in real time, of a movable mechanism and converts the temperature information into a temperature digital signal; a first wireless signal receiving and sending circuit receives the temperature digital signal and converts the temperature digital signal into a wireless signal; a second wireless signal receiving and sending circuit receives the wireless signal in a wireless transmission mode and converts the wireless signal into a digital signal; the testing computer displays and stores the digital signal in real time. The system and the method avoid adverse influences of the conductive sliding ring on temperature measurement.

Description

technical field [0001] The invention belongs to the technical field of industrial automation, and in particular relates to a wireless temperature measurement system and a measurement method for rotating equipment. Background technique [0002] In industrial production and testing equipment, some rotating equipment, such as test turntables, are often used. These rotating equipment generally use motors as driving devices. Such as figure 1 As shown, the rotating equipment is mainly composed of a fixed mechanism, a motor stator, a mover and its output shaft, and a movable mechanism. The motor stator is fixedly connected to the fixed mechanism, and the motor mover and the movable mechanism are connected through the motor output shaft. The parts are connected by bearings. After the rotating equipment is powered on, the movable mechanism in the rotating equipment starts to rotate. [0003] At present, in order to measure the temperature information of the movable mechanism in the...
