Connecting everything, wisely empowering the world | Firstrate meet you at the IOTE 2021 16th International Internet of Things Exhibition Shenzhen Station
  IOTE 2021 16th International Internet of Things Exhibition · Shenzhen Station will be held in Shenzhen Convention and Exhibition Center (Futian) on October 23-25, 2021. This is a carnival for the Internet of Things industry. At that time, Hunan Firstrate Sensor Co., Ltd. (abbreviation: Firstrate) will bring its blockbuster products to the exhibition site, bringing visitors a feast of Internet of Things technology and industry applications!     Firstrate Booth (Hall 2 2C2)   Highlights of the exhibition   This exhibition will bring smart fire protection, smart manhole cover, smart pipe gallery, smart water, smart environment, smart agriculture, smart property, Internet of Things transmission layer (5G), environmental monitoring weather station, multi-parameter water quality online analyzer And other series of products and IoT system solutions. Through the application of new-generation information technologies such as the Internet of Things, cloud computing, big data, and artificial intelligence, the Firstrate Internet of Things system can adapt to the needs of large-scale device connection applications in complex access environments, and can be deployed at low cost, flexibly and quickly. Kind of innovative IoT applications.             Smart Fire Internet of Things System   The Firstrate Smart Fire Internet of Things system includes a series of products such as smart gas cylinder monitoring series, smart fire hydrant monitoring series, wireless smoke detection series, etc., aiming at the fire protection hazards of fire water, combustible gas, and electrical fire in public places, the fire Internet of things is proposed The overall solution solves the characteristics of difficult monitoring of fire-fighting facilities, monitoring lag, and management blind spots, and realizes a fire-fighting facility management platform with real-time monitoring, timely maintenance and linkage alarms. Smart manhole cover IoT system   The Firstrate smart manhole cover monitoring sensor is installed under the manhole cover. When the sensor detects abnormal movement of the manhole cover, water immersion, and excessive methane gas, the sensor will report the alarm information to the base station in real time through wireless signals, and push the data to the manhole cover network system through the transmission network. In the server, after the management personnel see the alarm information, they will send someone to deal with it in time, so as to achieve the purpose of intelligent and fast management of the manhole cover, and then bid farewell to the hidden danger of the manhole cover.     Smart pipe gallery IoT system   Based on sensor technology, Internet of Things communication technology, configuration monitoring software, and pipe gallery platform monitoring terminal RTU, the Firstrate Smart Pipe Gallery IoT system realizes toxic and combustible gas, temperature and humidity, water pressure, water immersion, voltage and current. Real-time monitoring of other parameters, using the cloud platform and mobile network architecture, allows the staff to use computers and smartphones to view the real-time values of the monitoring parameters of the pipe gallery in real time. Once the data is found to be abnormal, the hidden dangers can be solved quickly and in time.       Smart Water IoT System   The Firstrate Smart Water IoT system adopts advanced sensor technology and cloud architecture mode to monitor various indicators of water quality online, which can accurately, timely and comprehensively reflect the current status and development trend of water quality, and provide water environment management, pollution source control, and environmental planning. Provide scientific basis for the entire water environmental protection and water pollution prevention and control plays a vital role.   Smart environment IoT system   ​The Firstrate intelligent environmental monitoring system adopts advanced sensing technology and cloud architecture mode to realize the collection of environmental data such as temperature and humidity, atmospheric pressure, wind speed and direction, rain and snow rainfall, PM2.5/PM10 air quality, etc., through wired or wireless It connects to the cloud to realize automatic storage of environmental data and online analysis and monitoring. Users log in to the system through PC or mobile terminals to obtain cloud services of environmental data and information in the environmental area. 物联网系列产品
