Wooden package temperature real-time detector

Abstract

The invention relates to a wooden package temperature real-time detector, which consists of a temperature probe, a shell and a control circuit arranged in the shell, wherein the temperature probe is connected with the control circuit in the shell through a cable; the control circuit consists of a sensor module, a current and voltage conversion module and a singlechip; the output port of the sensormodule is connected with the input port of the current and voltage conversion module in the shell through a cable; the output port of the current and voltage conversion module is connected with the input port of the singlechip; and the output port of the singlechip is connected with an input end of a microcomputer through a communication interface chip. The detector is scientific and reasonable in structural design, can monitor the temperature of a heat treatment storehouse in real time, accurately achieves the acquisition and transmission of temperature data, and has convenient management.

Description

technical field [0001] The invention belongs to the field of temperature measurement and control, in particular to a real-time temperature detector for wooden packaging. Background technique [0002] The quarantine treatment methods that have been approved in the international standard for phytosanitary measures "Guidelines for the Control of Wood Packaging Materials in International Trade" include heat treatment (HT) and methyl bromide fumigation treatment (MB). The standard stipulates that wood packaging materials must be treated according to the specified time and temperature. For heat treatment, the core temperature of the wood needs to reach 56°C and keep it for more than 30 minutes. The existing supervision on the quarantine treatment of wood packaging is basically a manual supervision mode, and the wood core temperature is detected by embedding a temperature measuring probe in the processed wood. Although this collection method can realize the measurement of the wood ...

AI Technical Summary

Problems solved by technology

The existing supervision on the quarantine treatment of wood packaging is basically a manual supervision mode, and the wood core temperature is detected by embedding a temperature measuring probe in the processed wood. Although this collection method can realize the measurement of the wood core temperature, there are still difficult problems. Problems: (1). This mode mainly uses manual reading of measurement data. It is difficult to maintain the continuity of the read data, which makes the processed data lose real-time performance, and it is difficult to control the start and stop time of heat treatment; (2). In the heat treatment process of the model, due to the long time of measuring data, the measuring personnel have a large workload and are prone to fatigue, so the phenomenon of omission and misrecording of temperature data often occurs; (3). The wood core temperature collected by this model cannot It is completely accurate, and there is no guarantee that the humidity in the heat treatment warehouse will reach the standard during the heat treatment process; (4). This mode is affected by various factors such as the material type, thickness, moisture content of the sampling wood block, and the buried seal of the probe.

[0003] To sum up, the manual supervision mode cannot monitor the data in the heat treatment process in real time. Its supervision timeliness is poor and supervision is insufficient. It cannot guarantee the accuracy and effectiveness of wood packaging quarantine treatment, and it cannot alleviate the shortage of quarantine supervision personnel and Solve the practical problems caused by many processing points, dispersion and long distance; increase the burden on the enterprise, and it is difficult to achieve the purpose of strict supervision
