The invention discloses an indoor positioning system based on electromagnetic distance measurement. The indoor positioning system comprises hydraulic cylinders, slide blocks, slide rails, square bosses, first air pumps, first pneumatic telescopic rods, a fixed base, an electromagnetic distance measurement instrument, an installation box, a control box, a control module, traveling wheels, a secondair pump, a fixed installation plate, a second pneumatic telescopic rod, a fixed connection rod, a motor, a limiting block, a belt, a connection rotating shaft, a tray, fixed blocks and a heatproof non-slip mat. The slide blocks are controlled by the hydraulic cylinders to move on the slide rails, and accordingly, the height of the tray is controlled; expansion and contraction of the first pneumatic telescopic rods are controlled by the first air pumps, so that the tray is controlled to stretch out; a client is positioned effectively through the electromagnetic distance measurement instrument,and thus, meals are delivered accurately. Through the indoor positioning system, meal delivering is stable, the situation that the tray is damaged due to the face that the temperature of food is toohigh is avoided, a waiter is prevented from being scalded by the food, the labor loss is reduced, positioning is accurate, and the inaccurate meal delivering situation is avoided.
Description
technical field [0001] The invention relates to the field of indoor positioning systems, in particular to an indoor positioning system based on electromagnetic wave ranging. Background technique [0002] Since the 1940s, the development of radar and various pulse and phase navigation systems has promoted people's in-depth research in the fields of electronic time measurement technology, phase measurement technology and high stability frequency source. On this basis, E. Bergstrand and T.L. Wadley successfully developed the first-generation photoelectric range finder and microwave range finder in 1948 and 1956 respectively. Electromagnetic distance measurement Electromagnetic distance measurement is a method of measuring the distance by using the electromagnetic wave as the carrier wave, which is emitted from one end of the measuring line after modulation, reflected or transmitted back by the other end, and the time interval between the transmitted wave and the echo is measure...
