Embodiment Construction

[0034] A specific implementation manner of an indoor air quality detection terminal of the present invention is given below in conjunction with the accompanying drawings, but it should be noted that the implementation of the present invention is not limited to the following implementation manners.

[0035] See attached figure 1 . An indoor air quality detection terminal, comprising a box body 1, a fan air inlet 2, an LED indicator light 3, a display screen 4, and a fan air outlet 5, and a core board, a sensor module, an LCD display module, and a power module are arranged in the box body 1 , fan module, LED indicator circuit and expansion interface. Casing 1 can adopt prior art to make with materials such as metal or timber or plastics or wood-plastic material. A fan air inlet 2 is arranged above the front of the box body 1 , an LED indicator light 3 is arranged in the middle, a display screen 4 is arranged below, and a fan air outlet 5 is arranged on the side of the box body...

Abstract

The invention relates to an indoor air quality test terminal, comprising a tank body, a fan air inlet/outlet, an LED (light-emitting diode) indicator light and a display screen, wherein a core board of the indoor air quality test terminal comprises a controller module and a radio frequency communication module; a sensor module comprises a temperature sensor, a humidity sensor, a carbon oxide sensor, a carbon dioxide sensor and an air quality sensor; an LCD (liquid crystal display) display module is used for displaying measurement parameters in real time; a power module supplies power to all the modules; a fan module is used for ventilation inside and outside the casing; an LED indicator light circuit prompts the working condition of the terminal in red, green or red-green; and a digital extended interface comprises an A/D (alternating/direct) conversion interface and an unappropriated I/O (input/output) port. The invention has the positive effects that: single composition detection ischanged into multiple composition detections, the requirement of HSE (health safety and environment) management of petrifaction enterprises can be met, the detected data can be displayed by a displayscreen or can be transmitted to a control room to be subjected to centralized monitoring by virtue of a ZigBee wireless sensor network, and the requirements of low cost and large-scale layout can be met, thus the terminal is applicable to popularization.

Description

technical field [0001] The invention relates to the technical field of analytical instruments (instruments), in particular to a terminal suitable for indoor air quality detection in petrochemical enterprises. Background technique [0002] With the continuous development of the petrochemical industry, the team of practitioners in this field is constantly growing. In order to retain talents and make full use of talents, they should be provided with a good working environment and opportunities for development. As early as 1996, internationally renowned petrochemical companies first proposed the concept of "HSE". "HSE" is the abbreviation of the trinity management system of Health, Safety and Environment, in which higher requirements are put forward for the working environment of workers, and the detection of indoor air quality is a better guarantee One of the means of working environment. [0003] The petrochemical industry has high requirements for the networking between eq...
