Abstract
The utility model provides a CO (carbon monoxide) gas detector which comprises a housing, a power source, a display screen, a control panel, a motherboard, a single chip microcomputer, a CO gas sensor arranged inside the housing, wherein an alarm is further arranged inside the housing. The CO gas detector can detect the concentration of CO gas in the air and make the judgment. If the CO gas concentration exceeds the safety limit, the CO gas detector gives the warning message. The CO gas detector has the advantages of simple structure, small size, light weight and convenience for carrying at various work sites.
Description
[technical field]
The present invention relates to the harmful gas pick-up unit, particularly a kind of hand-held inspection equipment that can detect CO gas.
[background technology]
Along with developing rapidly of industry, the place of human contact toxic and harmful is more and more, causes human harm own increasing thus.Each intoxication accident, the importance of recognizing protection mankind itself safety in developing industry that people are regained consciousness.Therefore various harmful gas warning instruments become requisite safeguard in the industrial safety production gradually.
China patent application CN 200810055883.0 discloses a kind of emergent wireless toxic gas indicator for chemicals leakage accident, and it comprises that wind direction, air velocity transducer, at least a above poisonous gas sensor and amplifying circuit, single-chip microcomputer and peripheral circuit thereof, GPS module, wireless sending module and antenna thereof, ID are provided with switch, power supply and power-switching circuit.This apparatus structure is comparatively complicated, and cost is higher, and a large amount of uses are caused certain limitation.
China utility model patent CN 200420029053.8 discloses a kind of integrated multi-functional harmful gas fast detecting instrument, comprise gas sensor, signal adjustment circuit, display and casing, described integrated multi-functional harmful gas fast detecting instrument is provided with data processing circuit and four kinds of sensors, four kinds of gas sensors are arranged in the casing, are provided with gas samping pump in the casing; Described signal adjustment circuit is provided with A/D converter, and signal adjustment circuit is used to accept, amplify the voltage and current signal of four kinds of gas sensors outputs, is converted into digital signal, and regulate zero point, measurement range and instrument drift is recompensed; Described data processing circuit is most data processing circuits, most data processing circuits are provided with the EPROM reservoir, data processing circuit is used to receive multiple signals to be adjusted the digital signal of circuit output and it is carried out linear process, sends into display and sends into the eprom memory storage.As can be seen, the apparatus structure complexity of this utility model, and also volume is bigger, is not easy to carry, so inconvenience is applied to the emergency relief scene.
[summary of the invention]
[technical matters that will solve]
The purpose of this utility model is to solve that existing gas detecting instrument complex structure, volume are big, the cost problem of higher, and a kind of simple, light, the novel C O detector that can carry is provided.
[technical scheme]
To achieve these goals, the utility model provides a kind of CO gas detecting instrument, comprise shell and power module, wherein, mainboard and the single-chip microcomputer, control panel, CO gas sensor, display screen and the attention device that link to each other with described mainboard electricity are housed in the described shell, 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 the CO gas concentration data that sensor determination obtains are sent information warning when being higher than designated value.
According to a kind of concrete preferred implementation of the present utility model, described sensor is an electrochemical sensor.The common ground of this class sensor is when in the testing environment tested gas being arranged, and sensor is translated into corresponding electric signal.After electric signal instrument internal circuit amplification after testing, the analog to digital conversion, carry out computing and processing, on liquid crystal display, directly demonstrate the concentration value of the gas of surveying then by the embedded scm on mainboard and the mainboard.When gas concentration reached the height warning limit value that sets in advance, the control function parts sent alerting signal.In the utility model, available sensor is Britain CITY company 4 series sensor for example, perhaps the AF series sensor of Alpha Co., Ltd.
The preferred implementation concrete according to another kind of the present utility model, described attention device are alarm lamp and/or hummer and/or vibrating device.According to attention device type difference, bright lamp, buzzing or vibration alarm prompting appear recording when CO gas concentration data are higher than designated value.
Preferably, be provided with wire gauze, can wrap up the sensor outer end, be used to intercept that dust, willow catkins flying in the air etc. may influence, the exotic of obstruction sensor in the outside of described sensor outer end.
More preferably, described sensor outside also is provided with sender unit cap, is connected with shell by screw thread, plays a protective role when detector is idle.
The preferred implementation concrete 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, the belt.
[beneficial effect]
The CO gas detecting instrument that the utility model provides is simple in structure, and volume is little in light weight, can carry all kinds of operation fields.
