Embodiment Construction
[0017] Such as figure 1 As shown, the principle architecture of the whole system is explained through 6 steps.
[0018] Part C1 is a module for joint detection of single or multiple gases, and supports users to choose different sensor group boards.
[0019] The C2 part selects and amplifies the electrical signal proportional to the gas concentration from the sensor. The digital-to-analog (AD) converter samples and converts the amplified signal into a digital signal (at least 12bit), and the upper application software (APP ) after synchronization, send the converted data through the USB port.
[0020] The C3 part is an intelligent mobile terminal with 3G / 4G / Wifi and GPS functions. Its USB port (supporting OTG) sends device enumeration information to the upper application software after the C1 module is inserted, and then C3 serves as the main device to supply power to the C1 module. Under the cooperative communication of the upper and lower layer software, the gas concentrati...

The invention discloses a smart mobile terminal-based gas joint detection and alarming system, which is characterized by comprising three modules, including a multi-gas joint detection module, a data sampling and communication module and a mobile terminal application software module (based on android, iOS, Windows and the like), wherein the multi-gas joint detection module can detect various gases, convert gas concentration into electric signals, and output the electric signals; the data sampling and communication module can transmit sampled data to a smart mobile terminal; and the application software in the mobile terminal application software module analyzes the data from multiple sensors, and provides real-time character (voice, SMS (Short Messaging Service)) prompts (alarm) of different levels according to the user settings and the binding of special phone numbers. If a user further sets a cloud server address, the gas joint detection and alarming system can obtain the position information transmitted by a built-in GPS (Global Position System) of the smart mobile terminal and finish uploading of data, which is convenient for information statistics and information mining among different plant areas or regions, even different countries. The normal sensor has limited service life, the gas joint detection and alarming system can support replacement of sensors, based on the periodic upgrading of the software, the sensor of a new generation is supported by an updated database, and thus, the testing precision and the alarming accuracy are improved. Because of popularization of smart terminals and deterioration of some local environments, the gas joint detection and alarming system can be used for real-time monitoring and alarming for a personal environment so as to realize the aim of self protection.
Description
technical field [0001] The invention relates to a gas detection and alarm system based on an intelligent mobile terminal, in particular to complete the joint detection of one or more gas concentrations, and complete data analysis, alarm and data upload through the application software based on the intelligent mobile terminal. [0002] Background technique [0003] While the development of the national economy has improved people's material living standards, it has also brought pollution to some parts of the environment, such as: the leakage of harmful gases from factories, and the harmful home or office air environment caused by unqualified decoration materials. People's health has brought great harm, and it has not been effectively improved at present. Therefore, it is necessary for people to pay attention to the detection and alarm of the air quality in the factory office and home living environment. At present, many kinds of harmful gas detection and alarm devices are m...
