Abstract
The utility model provides a handheld type O2 gas detector. The handheld type O2 gas detector comprises a shell, a power supply, a display screen, a control panel, a main board, a single chip microcomputer, and an O2 gas sensor mounted in the shell, wherein the shell is further provided with a warning indicator. The O2 gas sensor can be used for detecting O2 gas concentration in the air and judging; if the gas concentration is higher or lower than a safety value, the O2 gas sensor sends out warning information. The detector is simple in structure, small in volume and light in weight and can be carried to various working fields.
Description
Technical field
The present invention relates to gas-detecting device, particularly a kind ofly can detect O
2the hand-held inspection equipment of gas.
Background technology
At much industry, working-yard such as pit, underpass etc., in order to guarantee workmen's safety, often wish that the workmen can carry the oxygen detection device, oxygen content in environment can instant alarming higher or lower than to a certain degree the time, to guarantee workmen's personal safety.
China patent application CN200910071512.6 discloses a kind of oxygen concentration detecting instrument, adopt the input end of the output terminal connection driver of signal generator, the output terminal of driver connects the input end of tunable multimode diode laser, the output light of tunable multimode diode laser obtains directional light through the collimation lens transmission, directional light is divided into transmitted light and reflected light through spectroscope, transmitted light incides after the first condenser lens focuses on and incides the first photodetector after sample cell, reflected light finally incides the second photodetector as reference light, two ways of optical signals transfers electric signal to and inputs to computing machine by A/D converter, medium in sample cell is oxygen gas to be measured, the centre wavelength of tunable multimode diode laser is 760nm.This equipment can be used for detecting oxygen concentration.
May find out, the said equipment complex structure, volume is larger, and not only production cost is high, and is not easy to carry, and therefore is difficult to be widely used in the emergency relief scene.
Summary of the invention
The purpose of this utility model is to solve the problem that existing gas detecting instrument complex structure, volume are large, cost is higher, and a kind of simple, light, novel hand-held O that can carry is provided
2detector.
To achieve these goals, the utility model provides a kind of hand-held O
2gas detecting instrument, comprise shell and power module, wherein, mainboard and the single-chip microcomputer, control panel, the O that are connected with described mainboard electricity is housed in described shell
2gas sensor, display screen and attention device, the gas receiving end of described sensor stretches out described shell, a tabling of the screen portions of described display screen and described shell, described power module is connected with described mainboard, control panel, sensor and display screen respectively, to its power supply.
Described attention device is controlled by mainboard, if sensor is measured the O obtained
2the gas concentration data are sent information warning during higher or lower than designated value.
According to a kind of concrete preferred implementation of the present utility model, described sensor is electrochemical sensor.The common ground of this class sensor is that while in testing environment, tested gas being arranged, sensor is translated into corresponding electric signal.After electric signal instrument internal circuit amplification after testing, analog to digital conversion, by the embedded scm on mainboard and mainboard, carry out computing and processing, then on liquid crystal display, directly demonstrate the concentration value of surveyed gas.When gas concentration reaches the height warning limit value set in advance, control functional part and send alerting signal.In the utility model, available sensor I-01 type, FOS-65 type O that for example Shenzhen Fu Anda intelligence Science and Technology Ltd. sells
2sensor.
The concrete preferred implementation according to another kind of the present utility model, described attention device is alarm lamp and/or hummer and/or vibrating device.According to attention device type difference, recording O
2bright light, buzzing or vibration alarm prompting appear during higher than designated value in the gas concentration data.
Preferably, in the outside of described sensor outer end, be provided with wire gauze, can wrap up the sensor outer end, for intercepting, dust, willow catkins flying in the air etc. may affect, the exotic of obstruction sensor.
More preferably, described sensor outside also is provided with sender unit cap, by screw thread, with shell, is connected, and when detector is idle, plays a protective role.
The concrete preferred implementation according to another kind of the present utility model, there is clamping device at the described shell back side, can be fixed on detector on clothes, belt.
The concrete preferred implementation according to another kind of the present utility model, described display screen is touch-screen, for example adopts 3.2 inches touch-screens.
The O that the utility model provides
2gas detecting instrument is simple in structure, and volume is little lightweight, can carry all kinds of operation fields.
