Abstract

The invention relates to the technical field of display instrument systems and in particular relates to an ultrasonic display instrument system for a teaching laboratory. The ultrasonic display instrument system comprises an MCU (Microprogrammed Control Unit) processing unit, a display device high-voltage circuit, a keyboard scanning LCD (Liquid Crystal Display) controller, a PLL (Phase Locking Loop) module and a Bluetooth control module. The Bluetooth control module takes a Bluez Bluetooth protocol stack on a Linux operating system as a platform for developing; a host application program adopts a GCC (GNU Compiler Collection) compiler for compiling; a display terminal application program adopts arm-linux-gcc compiler for carrying out cross compiling, and Bluetooth control display is realized; an overcurrent protection detection signal is obtained by a sampling resistor R which is connected onto a backlight lamp tube in series and is conveyed to a driving control IC (Integrated Circuit); an overvoltage protection detection signal is obtained from L3 and is also conveyed to the driving control IC; when output voltage and working current of the backlight lamp tube are abnormal, the driving control IC is used for controlling a modulator to stop outputting, so that the protection effect is realized and the system is safer; the ultrasonic display instrument system has the advantages of simple structure and higher safety performance, realizes the Bluetooth control display and has very high practicability.

Description

technical field [0001] The invention relates to the technical field of display instrument systems, in particular to an ultrasonic display instrument system for teaching laboratories. Background technique [0002] Ultrasonic generators, also known as ultrasonic drive power supplies, electronic boxes, and ultrasonic controllers, are important components of high-power ultrasonic systems. The function of the ultrasonic generator is to convert the mains power into a high-frequency alternating current signal that matches the ultrasonic transducer, and drive the ultrasonic transducer to work. Considering the conversion efficiency, the high-power ultrasonic power supply generally adopts the circuit form of switching power supply. [0003] The ultrasonic power supply is divided into self-excited and other-excited power supplies. The self-excited power supply is called an ultrasonic analog power supply, and the other-excited power supply is called an ultrasonic generator. Internatio...
