Embodiment 1

[0056] Such as figure 1 As shown, a large-volume concrete wireless automatic temperature measurement device with temperature self-compensation function, including: NTC temperature sensor: set at the temperature monitoring point inside the concrete, and lead the temperature sensor to a suitable acquisition point through a three-core cable The main function of the NTC temperature sensor is to obtain the temperature information of the temperature detection point. This temperature sensor itself has a temperature compensation function. Good linear relationship, high precision, fast response, low cost and high stability.

[0057] Data acquisition module: connected to the temperature sensor through a three-core cable. The main function of the data acquisition module is to obtain and analyze the sensor serial number and current data information of the temperature sensor through communication with the temperature sensor.

[0058] Data storage module: connected with the data acquisitio...

Embodiment 2

[0064] A large-volume concrete wireless automatic temperature measuring device with temperature self-compensation function is the same as that in Embodiment 1, the difference is that the NTC temperature sensor encapsulates the NTC thermistor chip in a stainless steel shell through epoxy resin or fiber-reinforced resin bars inside, and the NTC temperature sensor is externally connected with a three-core cable (refer to figure 2 ). The technical parameter of described NTC temperature sensor is: R 25℃ =(10-20kΩ)±2.5%, B 25 / 85 =(3900-4200K)±2.0%, the temperature measurement accuracy is 1‰, and the temperature measurement range is -50~150℃.

Embodiment 3

[0066] A large-volume concrete wireless automatic temperature measurement device with temperature self-compensation function, the same as embodiment 1, the difference is: reference image 3 , design multiple groups of data acquisition modules to operate in parallel, and these data acquisition modules share a set of data processing modules, wireless data transmission modules, control centers and display devices, and each group of data modules is connected to multiple NTC temperature sensors.

[0067] The number of NTC temperature sensors can be selected according to the difference in concrete pouring thickness at each temperature monitoring point and the needs of temperature monitoring. One NTC temperature sensor can be set at each temperature monitoring point to realize efficient and wide-range temperature monitoring; two or more NTC temperature sensors can also be set at a certain temperature monitoring point at the same time, effectively avoiding the failure of a certain temp...

Abstract

The invention relates to the field of temperature monitoring devices of mass concrete, and particularly relates to a mass concrete wireless automatic temperature measurement device with a temperatureself-compensating function and application thereof. The device comprises an NTC temperature sensor, a data acquisition module, a data storage module, a data processing module, a wireless data transmission module, and a display device, wherein the NTC temperature sensor is arranged on a temperature monitor point inside concrete, the data acquisition module is connected with the sensor through a three-core cable, the data storage module is connected with the data acquisition module, the data processing module is used for packaging and processing data, a signal input end of the data processing module is connected with both the data acquisition module and the data storage module, an output end of the data processing module is connected with the wireless data transmission module, the wireless data transmission module is used for sending information obtained from the data processing module to a control center, and the display device displays the information. According to the temperature measurement device, the NTC temperature sensor is used for wireless automatic monitoring of mass concrete temperature for the first time, and when temperature does not need compensating, mass concrete temperature is monitored remotely, accurately, efficiently and intelligently.

Description

technical field [0001] The invention relates to the field of temperature monitoring devices for large-volume concrete, in particular to a wireless automatic temperature-measuring device for large-volume concrete with a temperature self-compensation function and an application thereof. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Mass concrete ("Mass Concrete Construction Standards" GB50496-2018 stipulates: the minimum geometric size of the concrete structure entity is not less than 1m mass concrete, or it is expected to be due to the temperature change and shrinkage caused by the hydration of the cementitious material in the concrete. Concrete that causes...
