3 results about "Microwave sensor" patented technology

The invention discloses a microwave sensor. The microwave sensor is characterized by comprising a power supply circuit, an oscillating circuit, an amplifying circuit, an output circuit and an indicating circuit, wherein the power supply circuit is used for supplying power for the oscillating circuit and the amplifying circuit; the oscillating circuit is connected with the power supply circuit; the amplifying circuit is connected with the oscillating circuit and the output circuit; the output circuit is connected with the amplifying circuit; and the indicating circuit is connected with the output circuit and comprises a light-emitting diode (LED) lamp. When the sensor is touched, the LED lamp is lighted. The oscillating circuit of the microwave sensor is adopted to generate microwaves and receive reflection waves without additionally arranging a microwave emission probe and a microwave receiving probe, so compared with other microwave sensors, the microwave sensor provided by the invention saves cost and eliminates the trouble of installing the microwave probes. The microwaves serve as detection means, so the microwave sensor is high in sensitivity and is not affected by the interference of sound waves; and the microwaves have strong penetrability, so the microwave sensor is easy to mount reconditely, is not easy to damage and is safer in use.

The invention belongs to the technical field of flow measurement, and particularly relates to a multiphase flow online real-time metering artificial intelligence model construction method. Oil-gas-water multiphase flow physical property parameters are various, and the flow process is complex, so that the development of a real-time flow measurement technology in an oil-gas production process is seriously restricted. The invention provides a multiphase flow online real-time metering artificial intelligence model construction method. The method comprises the steps of adopting Venturi measurementequipment, an electrical tomography sensor and a microwave sensor to cooperatively measure signals; by means of a deep encoding-decoding mode, under the condition that a large number of real flow sample tags do not exist, fully utilizing a large number of flow-tag-free measurement signals, and extracting the most basic constituent unit signals in the measurement signals; and constructing an artificial intelligence identification model of the flow of the measurement signal, the gas phase, the oil phase and the water phase according to the extracted minimum measurement signal forming unit. And meanwhile, the label-free measurement signal is fully utilized, so that higher measurement precision is realized.

The invention relates to a novel tri-proof light. The novel tri-proof light comprises a shell (7), seal rings (6), a left end cover (4), microwave sensors (14) and a right end cover (10). The shell (7) is in a long strip shape and is assembled together with the left end cover and the right end cover in a sealing mode through the seal rings (6). A double-track guiding structure (13) is fixedly disposed inside the shell (7). Guiding plates (13b) used for cooperating with the surface of the shell so as to clamp and fix a metal shell power source (8) are arranged on the lower portion of the double-track guiding structure (13). Guiding grooves (13a) used for clamping and fixing power panels are formed in the upper portion of the double-track guiding structure (13). Protruding blocks used for longitudinally positioning the microwave sensors (14) are disposed on the left end cover (4), and the microwave sensors (14) and the end covers are transversely positioned and fixed through screws. Clamping grooves (15) or clamping ribs used for being in seamless connection with another adjacent tri-proof light are formed in or disposed on the sides of the left and right end covers.
