Disclosed is a multi-channel early warning system for real-time monitoring of meteorological data, relates to the field of data monitoring technology, and comprises a meteorological data acquisition module, a meteorological data processing module, a terrain analysis module, a UAV deployment module, a ground situation acquisition module, an emergency degree analysis module, an early warning terminal, and a database. Data acquisition of a disaster-affected site is performed using a UAV. The UAV has the characteristics of being flexible and fast, and can be quickly deployed in a disaster-affected region to monitor the ground situation in real time, comprehensively assessing the impact of meteorological disasters. Then an emergency rescue level corresponding to the meteorological disaster site is analyzed, and different warning manners are provided for different emergency rescue levels, so that people's ability to monitor and respond to meteorological disasters can be greatly improved, and the relevant departments can take corresponding rescue and protection measures, thereby effectively reducing the impact and loss of disasters.

Multi-channel early warning systems for real-time monitoring of meteorological data

This invention is related to an apparatus which incorporates a microfabricated silicon mass flow sensor to measure city gas flow rate in a medium pressure range for utility industry which is dominated by conventional mechanical meters such as turbine and rotary meters. The microfabricated mass flow sensor is so called micro-electro-mechanical systems (a.k.a. MEMS) device. Due to the small feature size of micro scale for MEMS mass flow sensor, the invented apparatus includes many advantages such as low power consumption, compact package, high reliability and extended dynamic measurement range. This apparatus is also provided with a stable flow conditioning to achieve a desired dynamic range capability. Furthermore, because of the high accuracy characteristic, the apparatus in this invention could be applied for custody transfer or tariff in utility industry as well.

MEMS utility meters with integrated mass flow sensors

An all-electronic utility gas meter using with micromachined (a.k.a. MEMS Micro Electro Mechanical Systems) silicon sensor to measure gas metrology data for custody transfer or tariff in city gas metering application is disclosed in the present invention. The meter has two separate metrology units. One of the units is located in the main flow channel with the insertion probing configuration while the other is configured as a bypass unit assembly with the main metrology unit. The bypass metrology unit can perform independent metrology tasks and can be exchanged onsite during service, maintenance or repair without dismantle the meter from the service pipeline. The bypass metrology unit also can be used to compare the measured data from time to time and performance self-diagnosis that shall help the performance and data authentication during the meter field service. Both of the units can be powered by battery or external sources. The units can be connected to network as well as provide internal plural storages for data transmission and safety.
