First, announce the advantages of the system.
1. Our advantages in reforming the traditional fixed gas detection and alarm system.
Transmitting accurate alarm information to field workers in time through wireless technology will lead to zero accidents caused by human factors in the process of information transmission.
Detailed wireless transmission of alarm information: alarm position display, leakage concentration display, three-level early warning, acousto-optic vibration prompt.
Reduce the difficulty of transformation.
2. The alarm information transmission of portable gas detector has undergone revolutionary changes.
Wireless portable instruments can transmit alarm signals to each other, which can not only passively detect the gas environment, but also actively receive alarm signals from other convenient instruments.
It is realized that one person in the operation team gives an alarm, and other team members can know the gas environment in which the alarm person is located in time and accurately, which shortens the reaction time of the shift members and takes targeted measures according to the specific situation.
3. It fills the blank of online real-time monitoring of hot work site and confined space operation.
According to the requirements of GB3087 1-20 14 national standard, continuous and uninterrupted real-time monitoring of confined space operations that may release harmful substances is realized.
Let the alarm information in the confined space be timely and effectively transmitted to the security personnel outside the confined space, so that they can take corresponding rescue measures according to the gas environment in the confined space.
Second, innovative technology will lead the epoch-making progress of gas detection.
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 rarely involves the discussion of related applications, let alone similar products on the market. The technical level of this project is currently at the international leading level.
Three, limited space and temporary construction, emergency repair site operation, hot spot online monitoring and other necessary components to solve hidden dangers.
How to ensure the safety of 1, limited space, temporary construction and emergency repair has always been a topic that puzzles us. In recent years, there have been frequent safety accidents in this area.
Then, the main reason for the accident when working in a limited space is that the alarm information of the gas detector in the limited space can't be transmitted to the people outside the limited space in time, which leads to the fact that the outsiders can't grasp the changes of the gas environment in the limited space in time, thus losing valuable rescue time.
Then, how to solve this problem has become an urgent need. The mobile regional gas detection alarm device (GQB-200A7P) of Harbin Oriental Alarm is developed to solve the safety problems in limited space and temporary construction and emergency repair sites.
When the operator works in a confined space, put a 7P outside the confined space, send its suction hose (up to 50 meters) into the confined space and open it. In this way, the equipment (battery life 60~ 120) will continuously extract the gas in the closed space for real-time detection. When the internal gas environment changes and reaches the alarm value, the equipment will send out acousto-optic and wireless alarm signals. External security officers and managers can get accurate alarm information at the first time, and take corresponding rescue measures for the workers in the confined space in time. Reduce unnecessary casualties.
2. Safety problems in confined space and temporary hot work site.
The national standard GB3087 1-20 14 was implemented on June 1 this year. Why was it not implemented before? It is very necessary to monitor the confined space in real time by analyzing some workplace accidents in the past and summing up experience. There are often many accidents.
Past? What kind of operation link is the temporary operation site, including the confined space? What kind of workflow?
Before on-site hot work, the laboratory should go to the site to sample, analyze and test the gas environment, and the work can be carried out only after it meets the operating standards. During the operation, gas sampling and analysis shall be conducted every 4 hours or half an hour. It's also said that there will be 12 hour, and this cycle will continue until the end of hot work. This is intermittent, not real-time detection. There is a big omission in such an intermittent link: when the on-site workers are hot, there are several large time periods that are unsupervised, that is, gas leaks may occur during these time periods.
Therefore, there are two main reasons for casualties in confined space operations.
First, there is no real-time monitoring at the scene, the working environment is changing, and the field personnel don't know.
Second, you can only trust portable meters, but the alarm information transmission of portable meters is lagging behind.
Usually, when the portable watch notifies you, you have been in a dangerous environment for some time, which is fatal. For example, your portable instrument gives a first-class alarm of hydrogen sulfide, but it may be 2 meters away from you or even 1 meter with a distance of tens of thousands of PPM. (Let me talk about the concept of tens of thousands of PPM. If there is 100PPM of hydrogen sulfide in the confined space, the operator will faint in just two minutes, not to mention tens of thousands of PPM. ) So his lag is very dangerous.
How is our A7 applied in the open space? Take A7 downwind near the possible leakage point to monitor the site environment in real time. Once the operating point leaks, the equipment is first exposed to the change of gas environment, and then an alarm is generated and a wireless signal is sent to the surrounding team members. What's different from the past? Our mobile device GQB-200A7 didn't exist in the past. We were still under construction when the water leaked, so it was difficult for us to find this situation at the first time. When our portable instrument gives an alarm, the gas has spread to our space, which is very dangerous. And our A7 is at the leak point, so the dangerous gas comes into contact with A7 at the first time. When the gas has not floated near us, the wireless signal has told us where the alarm occurred before the gas, because the position of A7 can be edited, and then we will get the alarm information at the first time and then evacuate.
Fourth, break the traditional fixed detector gas detection mode.
"Xuanchuang Gas Detection and Early Warning Interconnection System"
Timely transmit accurate alarm information to on-site personnel, with rich effective information: position indication, concentration display, three-level early warning and acousto-optic vibration prompt.
Compared with the former mode, after the alarm in the former mode, the control room transmits signals to the site, and the information is inaccurate due to various factors (personnel, time, etc.). ). I don't know what gas is leaking, where it is, and what is the concentration of the leaked gas. What level of alarm? This caused some people to escape, but they fled in the wrong direction and fled to the leak site, thus losing their precious lives. Our equipment can transmit pre-edited location information through wireless signals. Leakage gas and its concentration. In other words, the field staff can know the exact leakage location and concentration through the portable gas detector developed by our company. (Let's talk about the electricity meter alarm in the 1 area, and synchronize 4S to receive acousto-optic vibration and voice alarm. ) In this way, the field staff can timely and accurately understand the specific situation of the accident point. Let the staff have a clear understanding of the accident point, reduce unnecessary panic, shorten the reaction time and win valuable escape time. Reduce the accidents caused by the failure of timely and accurate transmission of alarm information caused by human factors to zero.
The concept of Xuanchuang system is that every minute counts, with more warning and less danger!
I hope my answer can help you.
