Problems solved by technology

[0003] For the temperature measurement of the heating tube heating structure of the heating instrument, the temperature sensor used is wrapped inside the heating sleeve. If the heating tube is thrown away, the temperature sensor will be exposed to the air, and it will be known that the temperature sensor itself is faulty. Not allowed
When the temperature detection of the heating tube fails, it is impossible to control the temperature accurately, which will also lead to the failure of the over-temperature protection based on the temperature sensor

Embodiment 1

[0038] like figure 1 As shown, this embodiment provides a heating tube temperature monitoring device. A heating wire 2 and a temperature sensor 4 are arranged in the heating tube 1. Different from the prior art, this device is also provided with a metal wire 3 in the heating tube 1. The wire 3 is arranged around the heating wire 2 . For example, if the heating wire 2 is arranged in a rectangle inside the heating tube 1 , the metal wire 3 is another rectangular structure outside the rectangle surrounding the heating wire 2 .

[0039] The temperature sensor 4 is electrically connected with the heating controller 9 to realize single-point temperature measurement in the heating tube 1 . The heating controller 9 is also electrically connected to an alarm to realize over-temperature alarm or other abnormal alarm.

[0040] Based on the positive temperature coefficient / negative temperature coefficient of the metal wire 3 (the resistance value of the metal wire 3 increases / decreases ...

Embodiment 2

[0057] like image 3 As shown, on the basis of the first embodiment, this embodiment provides a temperature monitoring method for the heating pipe 1, which includes the following steps:

[0058] S1, the temperature sensor 4 detects the temperature of the detection point in the heating pipe 1 in real time, and transmits the temperature value of the detection point to the heating controller 9;

[0059] S2, the wire voltage collection circuit 7 collects the voltage of the wire 3 in real time, and transmits the collected voltage value of the wire 3 to the heating controller 9;

[0060] S3, the heating controller 9 judges whether the change state of the temperature value of the detection point is consistent with the change state of the voltage value of the metal wire 3;

[0061] S4, if it is inconsistent, the alarm will be controlled to give an alarm and the heating wire 2 will be powered off to stop heating.

[0062] The heating controller 9 judges whether the change state of th...

Abstract

The invention discloses a heating tube temperature monitoring device and method. Heating wires, metal wires and temperature sensors are arranged in the heating tube, the temperature sensor is electrically connected to a heating controller, and the heating controller is electrically connected to an alarm. The device includes a metal wire and a metal Wire voltage acquisition circuit; the metal wire is set in the heating tube and arranged around the heating wire; when the temperature change state detected by the temperature sensor is inconsistent with the metal wire voltage change state detected by the wire voltage acquisition circuit, the heating controller controls the alarm to alarm and control The heating wire is powered off to stop heating. The invention has a simple structure, can provide double protection for the over-temperature protection of the heating tube, and improves heating safety; the overall heating condition of the heating tube can be reflected by using the metal wire; a common point is set on the metal wire, and the metal wires on both sides of the common point are collected If the difference between the two is large, it means that the left and right sides of the heating tube are heated unevenly, and the monitoring of the aging problem of the heating wire can be realized.

Description

technical field [0001] The invention relates to the field of heating pipe temperature monitoring, in particular to a heating pipe temperature monitoring device and method. Background technique [0002] The medical blood transfusion infusion warmer can heat the blood or medicine injected into the human body, which can avoid the soreness of the injection site and the chills of the patient after the refrigerated blood or the lower temperature medicinal liquid is injected into the human body intravenously. reaction. [0003] For the temperature measurement of the heating tube heating structure of the thermometer, the temperature sensor used is wrapped inside the heating sleeve. If the heating tube is thrown away, the temperature sensor will be exposed to the air, and the failure of the temperature sensor itself will lead to the measurement of the temperature. Warm is not allowed. When the temperature detection of the heating tube fails, it is impossible to accurately control t...
