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] Such as figure 1 As shown, the present embodiment provides a heating tube temperature monitoring device, in which a heating wire 2 and a temperature sensor 4 are arranged in the heating tube 1. The difference from the prior art is that the 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, the heating wire 2 is arranged in a rectangular shape inside the heating tube 1 , and the metal wire 3 is another rectangular structure surrounding the heating wire 2 outside the rectangle.

[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 an over-temperature alarm or other abnormal alarms.

[0040] In this embodiment, based on the characteristics of the positive temperature coefficient / negative temperature coefficie...

Embodiment 2

[0057] Such as image 3 As shown, on the basis of the first embodiment, this embodiment provides a temperature monitoring method for the heating tube 1, including the following steps:

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

[0059] S2, the wire voltage acquisition 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 inconsistent, control the alarm to give an alarm and control the heating wire 2 to cut off the power to stop heating.

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

Abstract

The invention discloses a heating pipe temperature monitoring device and method, a heating wire, a metal wire and a temperature sensor are arranged in a heating pipe, the temperature sensor is electrically connected with a heating controller, the heating controller is electrically connected with an alarm, and the device comprises the metal wire and a metal wire voltage acquisition circuit; the metal wire is arranged in the heating pipe and is arranged around the heating wire; and when the temperature change state detected by the temperature sensor is inconsistent with the metal wire voltage change state detected by the metal wire voltage acquisition circuit, the heating controller controls the alarm to give an alarm and controls the heating wire to be powered off to stop heating. The structure is simple, double guarantees can be provided for overtemperature protection of the heating pipe, and the heating safety is improved; the overall heating condition of the heating pipe can be reflected by utilizing the metal wires; and a common point is set on the metal wire, the voltage of the metal wire on two sides of the common point are collected and judged, and if the difference is large,it is indicated that the left and right sides of the heating pipe are non-uniformly heated to monitor the aging problem of the heating wire.

Description

technical field [0001] The invention relates to the field of temperature monitoring of heating pipes, in particular to a temperature monitoring device and method for heating pipes. Background technique [0002] The medical blood transfusion infusion warming device can heat the blood or medicine injected into the human body, which can avoid adverse effects such as soreness at the injection site and chills in the patient's body caused by refrigerated blood or low-temperature medicinal liquid injected into the human body through the vein. reaction. [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. The temperature is not allowed. In the case of failure of the temperature detection of the heating tube, it i...
