Abstract

The invention discloses a concrete internal temperature detection device based on induction principle including the devices buried inside and outside of concrete. The internal device includes temperature sensor, the second CPU, modulation circuit and the second coil, which is used to receive and process the internal temperature information, and code the information for the signals external device can identify to send out. The external device includes the first coil, oscillation power amplification circuit, analog processing circuit, the first CPU and a communication interface, which are used to receive data from internal device, decode them to communicate with PC and provide energy for the internal device.

Description

technical field [0001] The invention belongs to the technical field of temperature detection, and relates to a temperature detection device, in particular to a temperature detection device applied to the interior of concrete without external electrical contacts and power supply in construction projects such as roads, bridges, and railways. Background technique [0002] In the pouring process of laying railway concrete, the temperature change inside the concrete has a great influence on the quality of the concrete pouring parts. If it is not controlled, it will seriously affect the pouring quality and life of the concrete. At present, there are the following three methods for the internal temperature detection Main problems: (1) It is impossible to directly supply power to the data acquisition equipment, which brings restrictions on the power consumption of the data acquisition equipment; (2) The data acquisition equipment cannot directly lead out the signal detection line fro...
