[0003] At present, multiple patents have proposed a methane carbon monoxide detector, such as patent CN204269536U, which proposes a portable methane carbon monoxide detector, which uses an infrared detection head as a gas sensor, has high manufacturing costs, high processing accuracy, and is difficult to apply in coal mine devices; patent CN103529089A A wearable methane carbon monoxide detector is proposed, and the module structure is not clear; patent CN202486085U proposes a methane carbon monoxide detector with a complex circuit structure; most of these detectors have poor sensitivity and stability, single functionality, and short working hours The disadvantage is that it is not suitable for mining in mines, and the detection range of dangerous gases is too small, which reduces the safety performance to a certain extent.

The invention relates to a CJT4 / 1000X suspended type methane and carbon monoxide detector. An acoustic window, a viewing port, a warning lamp opening and a key entrance are formed in the surface of an enclosure cover; a methane gas inlet, a carbon monoxide gas inlet and a suspended pull ring are formed in the top of an enclosure box; an emergency lamp mouth, an emergency lamp switch, a power supply charging socket and an external power supply connector are formed in the lateral surface of the enclosure box; a methane sensor, a carbon monoxide sensor, an A / D (Analog / Digial) converter, a circuit main board, a power supply, an emergency lamp and an emergency lamp power supply are arranged in the enclosure box; alarms, a display panel, keys, a wireless transceiver module, a data storage chip and a singlechip microcomputer are arranged on the circuit main board; the alarms comprise an acoustic alarm, a visual alarm and a vibration alarm. The CJT4 / 1000X suspended type methane and carbon monoxide detector disclosed by the invention has the characteristics of multiple functions, high sensitivity and high stability; wide-range and long-time determination and early warning of methane and carbon monoxide underground a coal mine can be realized.
Description
technical field [0001] The invention relates to a CJT4 / 1000X suspended methane carbon monoxide detector, which belongs to the technical field of gas measuring devices. Background technique [0002] In coal mine operation environment, flammable gases such as methane and carbon monoxide are easy to be produced. When these gases exceed a certain limit, they will explode and endanger the safety of underground personnel. Therefore, a dual-purpose monitoring and alarm instrument for methane and carbon monoxide detector is proposed, which can detect methane Carbon monoxide concentration, the alarm will be realized after the threshold, effectively preventing safety accidents. [0003] At present, multiple patents have proposed a methane carbon monoxide detector, such as patent CN204269536U, which proposes a portable methane carbon monoxide detector, which uses an infrared detection head as a gas sensor, has high manufacturing costs, high processing accuracy, and is difficult to appl...
