Embodiment 1

[0013] above as figure 1 , figure 2 The shown hydrogen concentration detector with temperature measurement function includes a housing 1 and a display screen 3 disposed on the housing 1, and also includes a control button 4 disposed on the housing 1 and a temperature sensor 2 at the center of the top surface , an integrated circuit board arranged in the casing 1, the integrated circuit board is provided with a signal processing circuit and a single-chip microcomputer;

[0014] The hydrogen concentration detector with temperature measurement function has the function of temperature measurement while detecting the concentration of hydrogen gas. It can not only detect the concentration of hydrogen gas, but also detect the temperature within the range of hydrogen gas leakage, and judge whether there will be an explosion. Take precautions.

Embodiment 2

[0016] Above-mentioned temperature sensor 2 is used for ambient temperature, and sends signal to signal processing circuit; Said signal processing circuit is used for receiving the signal that temperature sensor sends, and carries out digitization, then sends signal to single-chip microcomputer; Said single-chip microcomputer is used for receiving control The command of the button and the signal sent by the signal processing circuit are judged, and then the display screen is controlled to display the distance information; the model of the temperature sensor is: PT1000, and the model of the single-chip microcomputer is: AT89C51.

Abstract

Belonging to the technical field of instruments and meters, the invention in particular relates to a hydrogen concentration detector with a temperature measurement function. The hydrogen concentration detector comprises a shell and a display screen disposed on the shell, and also includes control buttons and a temperature sensor arranged at the center of the top surface, and an integrated circuit board inside the shell. The integrated circuit board is provided with a signal processing circuit and a single chip microcomputer. The hydrogen concentration detector with the temperature measurement function has the temperature measurement function at the same time of hydrogen concentration detection, not only can detect the hydrogen concentration, but also can detect the temperature in the range of hydrogen leakage, and judges whether explosion occurs, thus taking prevention measures accordingly.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and in particular relates to a hydrogen concentration detector with a temperature measuring function. Background technique [0002] The hydrogen detector is an intrinsically safe device that can continuously detect the concentration of toxic gases and is suitable for explosion-proof places. The hydrogen detector is sensitive and accurate to the hydrogen concentration, which can ensure that it can give you an alarm in time when hydrogen leaks. Existing hydrogen gas concentration detectors have relatively simple functions, only the function of detecting hydrogen gas concentration, and do not have the function of temperature measurement. They cannot measure whether the temperature will cause an explosion, and cannot accurately estimate the danger caused by hydrogen gas leakage. Contents of the invention [0003] The purpose of the invention is to overcome the problem that the exist...
