Automatic numbering device and method for temperature sensors

Abstract

The invention discloses an automatic numbering device and method for temperature sensors. The device comprises a power supply circuit, a sensor drive circuit, a display circuit, an input circuit, and a data processing circuit. The method comprises following steps: performing integration to a temperature function of kth time measurement of a temperature sensor at the nth position on a temperature measurement axis to obtain an integral function of integral Tn<k>, n belongs to (k-1, k); comparing a maximum function: {Maximum value of absolute value of [integral Tn<k>, n belongs to (k-1,k)-integral Tn<k>, n belongs to (k-2, k-1)]}, of absolute values of temperature difference between the current temperature integral function of [integral Tn<k>, n belongs to (k-1, k)] of a sensor at the nth position and the last time temperature integral function of integral Tn<k>, n belongs to (k-2, k-1) with a set temperature difference threshold Tc; when a temperature value of the maximum function: {Maximum value of absolute value of [integral Tn<k>, n belongs to (k-1,k)-integral Tn<k>, n belongs to (k-2, k-1)]}, is larger than the temperature difference threshold Tc, then the temperature sensor at the nth position is automatically numbered; repeating above steps until all the temperature sensors of the temperature measurement axis are automatically finished numbering. The method has small time consumption and high accuracy; by use of the device and method, automatic numbering of temperature sensors can be realized, work efficiency is increased, and the cases of omissions and errors due to artificial numbering are avoided.

Description

technical field [0001] The invention relates to a temperature sensor sorting and numbering device in the technical field of building construction, in particular to a temperature sensor automatic numbering device and method. Background technique [0002] In recent years, with the trend of complex and large-scale building structures, large-volume concrete structures have emerged at home and abroad. In order to ensure that the construction quality of the mass concrete structure meets expectations, real-time monitoring of the concrete temperature distribution during the construction of the structure is required. At present, it is generally used to bury a large number of temperature sensors inside the concrete and collect the sensor measurement data in real time through intelligent acquisition nodes to achieve monitoring purposes. These large number of temperature sensors are distributed on several temperature measuring axes, and the temperature measuring axes are buried in In t...

Problems solved by technology

[0010] 2) Time-consuming

Since the sensitivity of temperature sensors is generally low, it takes about 10s to 15s to see the value after the temperature change, so hundreds of sensors are numbered sequentially, which takes a long time

[0011] 3) High error rate

The above two methods are still manual operations in essence. In the process of sensor numbering, due to the negligence of the operator, it is easy to cause numbering omissions or errors.
