230 hazardous gas sensors in the West District of Zhongguancun

Beijing Youth Daily reporter learned from Haidian District yesterday that 230 underground toxic and harmful gas sensors have been installed in the above-ground and underground areas of the Zhongguancun West District. The “neural system” for the “urban brain” of Haidian District is used to monitor hydrogen sulfide, carbon monoxide and oxygen. , methane, ethane and other gases.

The sensor can monitor the content of pollutants such as hydrogen sulfide in real time.

Recently, Beiqing Daily reporter came to the Zhongguancun West District adjacent to the North Fourth Ring Road, which is the core of the core area of ​​Zhongguancun Science City. Below the ground there is a comprehensive pipe gallery with a length of about 1500 meters, which is closed. The integrated pipe gallery has three underground floors, one of which is a circular driveway, one-way counterclockwise, connecting with the main buildings in the area; the second basement is a garage and commercial development area; the third underground is the energy main gallery, natural gas, The five major pipelines of telecommunications, water, electricity and heat are distributed here.

Walking into the water supply pipe gallery, you can see that many small boxes are installed on the wall, and there is one every 30 meters. “This small box is a newly installed toxic and harmful gas integrated sensor that monitors hydrogen sulfide, carbon monoxide, oxygen, methane, ethane, etc. It also senses temperature. A total of 65 sensors are installed in the water supply pipe, monitored every two hours. Once, the technical staff of Haidian District Urban Intelligence Center introduced that in the past, gas monitoring was mainly done manually. When the staff entered the underground integrated pipe gallery, they carried a hand-held detector with them. It took about two hours to patrol a circle, and there were certain safety risks.

Automatic monitoring of the system has been achieved since the installation of a toxic and hazardous gas integrated sensor in the underground integrated pipe gallery. The data is uploaded to the “City Brain” intelligent control center, property management department and ownership unit in time. Once abnormal data is found, emergency personnel can obtain information in a timely manner and solve the problem in the first place.

Automatic monitoring of the monitoring sensor when the manhole cover is tilted

According to the relevant technical personnel, 165 toxic and harmful gas integrated sensors were installed in the shafts such as thermal wells, gas wells and water supply wells on the main roads in the central area of ​​Zhongguancun. The total number of pilot installations reached 230, and will continue to be promoted in the future. At the same time, 290 sensors for monitoring the displacement of the well are installed under the pavement manhole cover. When the tilting angle of the manhole cover is greater than 15°, the alarm signal will be automatically uploaded, and the emergency management personnel will be notified through the “City Brain” intelligent control center to avoid the manhole cover. Tilting or losing, posing a danger to pedestrians and vehicles.

Zhongguancun West District becomes the first unguarded block

The reporter of Beiqing Daily saw on Danling Street that the isolated barriers on the road were all gone, and the roads were both open and beautiful. Wei Dong, deputy director of the Zhongguancun West District Administrative Committee Office, said that the previously installed guardrails played a role in security and also caused pedestrians to pass poorly. To this end, the renovation removed all the guardrails in the area, and the Zhongguancun West District became the first block in the city without guardrails.

After the traffic isolation barrier was cancelled, the Haidian District Traffic Commission optimized the road traffic facilities, re-routed the traffic markings, replaced the non-isolated guardrails with flower beds, added stereo zebra crossings, and added monitoring probes. The Zhongguancun West District Office also organized a team of assistants for manual grooming.

In addition, at the crossroads with large traffic, five face recognition probes were installed to capture pedestrians' red lights. The reporter of Beiqing Daily stood at the northeast corner of the intersection of Danling Street and Haidian Middle Street. He saw a video of a pedestrian red light being scrolled on a large screen, including a 10-second full-time record and a 5-second close-up shot. The eyes were occluded. .
