Double-chamber multifunctional pumping type environment detector

Abstract

The invention discloses a double-chamber multifunctional pumping type environment detector, belongs to the technical field of environment detection, and aims to solve the problems of low detection reliability, single function, low integration level, low gas detection sampling speed, large detection error and the like of an existing environment detector in a low-temperature environment. The detector comprises a shell, the shell is provided with a first-stage chamber and a second-stage chamber, a heat insulation layer is filled at a separation part of the first-stage chamber and the second-stagechamber, the first-stage chamber is provided with an air inlet, the second-stage chamber is provided with an air outlet, a temperature and humidity sensor is mounted in the first-stage chamber, a dust sensor and an air pump are installed at the separation part of the first-stage chamber and the second-stage chamber, a heating block is installed at the outlet end of the air pump, a plurality of gas sensors are installed in the second-stage chamber, flexible metal electrothermal films are installed on the gas sensors, and a signal processing module and a microprocessor are further installed inthe second-stage chamber. The invention is suitable for the double-chamber multifunctional pumping type environment detector.

Description

technical field [0001] The invention belongs to the technical field of environmental detection, and in particular relates to a double-chamber multifunctional pump suction type environmental detector. Background technique [0002] Environmental detectors are mainly composed of temperature and humidity sensors, gas sensors, dust sensors, gas sensors, signal acquisition and conditioning circuits, control circuits, etc., use different sensors to collect corresponding environmental information, and then after signal amplification, filtering, etc., input The microprocessor performs comprehensive analysis and centralized processing, outputs environmental information through the output interface (display screen, electrical connector, etc.), and gives sound and light alarm when necessary. [0003] The existing environmental detectors can complete the detection of environmental information well, but there are still some defects in the use of the products, which are mainly manifested i...
