Research and application of gas detection alarm intelligent verification device

[China Instrument Network Instrument Research and Development] Shandong Province Science and Technology Research Institute, Shandong Province Science and Technology Agency, Jinan Science and Technology Bureau Project “Research and Application of Intelligent Detection Device for Poisonous and Inflammable and Explosive Gas Detectors and Alarms” 2015 The State Administration of Quality Supervision, Inspection and Quarantine of Science and Technology Award, second prize.

The project has studied key technologies such as automatic gas distribution, automatic data acquisition, and remote data processing. Based on the theoretical simulation of the accuracy of the automatic gas distribution system, an automatic gas distribution device was designed and developed, and gas detection based on machine vision technology was developed. The alarm verification device and gas alarm verification intelligent control terminal have developed a network intelligence management system for verification data. The developed smart verification device meets the requirements of JJG678-2007, JJG693-2011, JJG915-2008 and other metrological verification regulations. Its gas distribution accuracy is ±1.0% (concentration point), image acquisition and recognition rate is 100%, and the data processing system average response time Less than 5 seconds; with remote control control function, the device provides an open data communication interface.

A total of 8 papers were published in the project, of which 1 was included in SCI; 2 invention patents and 2 utility model patents, and 2 software copyrights were obtained. The project results have been applied to Xinwen Mining Group, Jinan Changqing Computer Application Company and Jinan, Heze metrology and technical organizations and other units, generating economic benefits of more than 500 million yuan, greatly improving the detection efficiency and verification quality of toxic and harmful gas detection and alarm devices. Remote control and information feedback are realized. The promotion and application of the results has provided scientific and technological support for the construction of "Peaceful Shandong" and safe China, and the construction of a harmonious society. It is of great significance for safeguarding the health and safety of personnel.
