Embodiment Construction

[0038] As a UsCell (the name of the node of the present invention) node with ultrasonic transceiver function, it is mainly composed of multiple power supply modes, an ultrasonic processing chip and an ultrasonic transmitting and receiving head. It has the functions of multi-mode power supply, ultrasonic transmission and reception at a certain distance, etc. Strong practicability and wide range of applications. The transmitter node is connected to the wireless sensor node through the 51-pin standard expansion interface, and the wireless sensor node controls the emission of the ultrasonic transmitter head; the receiver node receives and processes the ultrasonic signal of the transmitter head by the ultrasonic receiver head, and sends an interrupt through the 51-pin standard expansion interface The signal is sent to the wireless sensor node, so as to realize the sending and receiving of ultrasonic signals.

[0039] The invention provides an ultrasonic sending and receiving node ...

Abstract

The invention discloses an ultrasonic receiving and sending node and an implementation method thereof, relates to the design and implementation method of the ultrasonic receiving and sending node applied to indoor ranging and the implementation method thereof, provides an example of the ultrasonic node, and mainly solve the problem of wireless sensing under a high frequency condition. A sensor node takes a processing control module (1) as a center, an information sensing module (2) is unidirectionally communicated with the processing control module (1), and a power supply module (3) provides energy to the whole node in an integrated power supply manner, wherein, the processing control module (1) comprises a sending part which is an inverter 74HC04 with six channels and a receiving part which is an infrared remote control receiver CX20106; the information sensing module (2) comprises TR-40 series universal ultrasonic sending and receiving sensors; and the power supply module (3) has three power supply modes which are wireless node supply, AC / DC power supply and DC / AC power supply. The design and the implementation of the node realize the ultrasonic receiving and sending function in terms of the function, and have lower power consumption and meet various needs by different power supply modes.

Description

technical field [0001] The invention relates to a design and realization method of an ultrasonic transceiver node applied to indoor distance measurement. An example of an ultrasonic node is given. It mainly solves the problem of wireless sensing under high frequency conditions, and belongs to the field of ultrasonic research. Background technique [0002] In an elastic medium, if the frequency excited by the wave source is between 20Hz and 20000Hz, it can cause human hearing. The vibration in this frequency range is called acoustic vibration, and the longitudinal wave excited by the acoustic vibration is called sound wave. Ultrasound is based on the frequency of sound waves that can be heard by the human ear. Its frequency is higher than 20000 Hz, and it is called an inaudible sound wave. [0003] Compared with audible sound waves, ultrasonic waves have the following characteristics due to their high frequency and short wavelength: [0004] (1) Good directionality. Due ...
