It is learned from Haidian District, and the underground area of Zhongguancun is recently installed with 230 poisonous gas sensors, which is a "nervous system" for the "urban brain" in Haidian District. It is used to monitor hydrogen sulfide, carbon monoxide, oxygen, methane, ethane, etc. gas. When an abnormal data is found, the emergency management personnel can be notified in a timely disposal of emergency management. In addition, Zhongguancun West Region has also completed the transformation and improvement, and built a model between the construction of a new urban form in Haidian District. Recently, the North Youth Daily reporters came to Zhongguancun West, Northern Fourth Ring Road, which is the core of the core area of Zhongguancun Science City. There is a comprehensive gallery of about 1500 meters below the ground, which is closed. There are three three floors in the integrated gallery, of which the underground layer is an annular lane, a one-way counter-hour, communication with the main buildings in the region; the underground two is a garage and commercial development area; the ground three is the energy main gallery, natural gas, The five major pipes such as telecommunications, water, electric power, and heat are distributed here. Enter the water supply pipe gallery, you can see many small boxes installed on the wall, there is one around 30 meters. "This small box is a recent newly mounted toxic and harmful gas integrated sensor, which can monitor hydrogen sulfide, carbon monoxide, oxygen, methane, ethane, etc., can also sense temperature. A total of 65 sensors in the water supply gallery, monitoring every two hours Once. "Haidian District City Wisdom Center Technician introduced that the past gas monitoring mainly rely on manual completion, when the staff entered the underground integrated gallery, carry a handheld detector with you, and the inspector takes about two hours, and there is still a certain security risk. The system automatic monitoring can be achieved since the toxic and harmful gas integrated sensor is installed in the underground integrated gallery. Data is uploaded to the "City Brain" Wisdom Control Center, the property management department and the right unit. Once an abnormal data is found, the emergency personnel can get information in time, and solve the problem in the first time. Shenzhen Working Network Co., Ltd. provides a gas sensor applied to underground integrated gallery, including H2S, CO, O2, CH4, and specific products as follows: H2S sensor H2S-A1 features: Electrochemical principle 4 series size H2S range: 0 ~ 100PPM linear output can anticipate the characteristics of the CO sensor CO-AM of NH3, H2, C2H4: the range of 0 to 5000 ppm is high, 15 ppm linear output zero drift is small, 2 ppm / annual oxygen sensor KE-25 characteristics: * Long life, air environment 2.5 ~ 10 years * Almost unreffected by CO2, CO, H2S, NOx, H2 * Low cost * Normal temperature operation * Stable signal output * Sensor work without external power supply * No preheated CH4 sensor CH- A3 features: The catalytic combustion principle range is 0 ~ 5% VOL response speed, which is 15 second linear analog voltage output.
