Abstract

The invention discloses a single-pipe pipeline type switch. The single-pipe pipeline type switch includes a host machine and an ultrasonic probe which are connected with each other; the host machine includes a controller, a non-resonant ultrasonic transmitting circuit, a small signal receiving circuit and a display device; one end of the non-resonant ultrasonic transmitting circuit is connected with the ultrasonic probe, and is used for transmitting signals to the ultrasonic probe; the other end of the non-resonant ultrasonic transmitting circuit is connected with the controller; one end of the small signal receiving circuit is connected with the ultrasonic probe and is used for receiving signal emitted by the ultrasonic probe; and the other end of the small signal receiving circuit is connected with the controller; the controller is provided with an infrared interface; and the controller is an ARM Cortex-M3 core STM32F103 single-chip microcomputer. The installation of the single-pipe pipeline type switch is simple and fast.

Description

technical field [0001] The invention belongs to the technical field of switches, and in particular relates to a single-point pipeline switch. Background technique [0002] In the field where conventional liquid level gauges and switches on industrial pipeline sites and infusion pipelines cannot alarm, it is difficult to apply traditional switch alarms, which cannot meet the early warning needs of special working environments. In order to warn the liquid level of the pipeline under complex working conditions, the development of a single-point pipeline switch is of great significance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single-point pipeline switch that is easy and fast to install in view of the above-mentioned deficiencies in the prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is that the single-point pipeline swit...
