On June 201May 12, China Chemical Safety Association organized an expert review meeting on gas detection, early warning and forecasting system in inspection and maintenance operations in Shijiazhuang, Hebei.
At the meeting, Harbin Dongfang Alarm Equipment Development Co., Ltd., the system developer, introduced the development process, patents obtained and application in domestic petrochemical enterprises. As one of the application units of the system, the person in charge of the application engineering of Shijiazhuang Refining and Chemical Company of China Petrochemical Company introduced the application of the system, and the participants also reviewed the relevant technical data of the system patent application. After the meeting, the association organized all participants to observe the field application drill of the system in Shijiazhuang Refining and Chemical Diesel Hydrogenation Unit.
It is considered that the technology of the system embodies the people-oriented safety concept, realizes the goal of transmitting the information of environmental change status of overhaul operation to the operators first, and meets the requirements of all-weather monitoring of dangerous areas and timely transmitting the information of environmental change status to the surrounding operators. The system provides technical support for strengthening the detection of working environment and the management of working links, wins valuable time for dealing with dangerous situations in the working process in time, and provides timely early warning for emergency personnel to protect themselves and prevent accidents from expanding. System technology is at the leading level in the same industry in China, which is worth popularizing.
16 safety management and testing technical experts from PetroChina, Sinopec, CNOOC, China Chemical, Huabei Pharmaceutical and other units, as well as more than 20 persons in charge of related enterprises and technical service institutions attended the review meeting.
Final opinion: The products of Harbin Dongfang Alarm Equipment Development Co., Ltd. are scientific, reasonable, practical, stable and reliable, and are at the leading level in the same industry at home and abroad. It is recommended to popularize it!
? The system adopts wireless alarm technology, organically combines the on-site fixed combustible toxic gas detector with the portable combustible toxic gas alarm, expands the function of the original fixed combustible toxic gas detector, expands the alarm range, realizes the isolation of operators from dangerous environment, and can effectively avoid the death of personnel.
On the whole, shorten the reaction time of personnel, increase the reaction time of personnel, improve the survival probability of personnel and reduce the accident rate.
Innovation: The innovation of this project lies in the application of Internet of Things technologies such as wireless communication technology, mobile development technology and distributed information processing technology. , realizing the interconnection of detection and personnel and disposal institutions in the field of gas detection and alarm, so as to realize effective detection and alarm and reduce the loss of life and property.
Key technologies: Key technologies include stable wireless communication technology, gas detection technology, intrinsically safe explosion-proof technology and distributed information processing technology.
Technical level: the development and application of this project is based on the retrieval of relevant journals, patents and domestic and foreign industry technologies, and there is little discussion on related applications, let alone the same products on the market. The technical level of this project is currently at the international leading level.
