Problems solved by technology

However, the current physical parameter display instruments of the circuit breaker characteristic detection test bench all display a single physical parameter. To realize simultaneous display of multiple parameters, multiple instruments need to be combined at the same time.
This makes data collection more cumbersome and complicated, and at the same time causes a waste of resources

Abstract

The invention relates to a breaker characteristic detection comprehensive physical parameter display instrument and a control method. The display instrument comprise an analogue signal input terminal, digital control signal input terminals, an analogue signal processing circuit, a single chip, a liquid crystal screen communication terminal, a liquid crystal display LCD screen and a switch power module; the analogue signal input terminal inputs a signal in the analogue signal processing circuit, then inputs the processed signal in a single chip AD (analog/digital) sampling channel; each digital control signal input terminal inputs the signal to an I/O input port of the single chip; the single chip inputs the to-be-displayed signal in the LCD screen by the liquid crystal screen communication terminal through an output port; and the switch power module is the power source of the single chip and the signal processing circuit. One or more parameters can be acquired simultaneously according to demands, and one or more parameters can be displayed according to the demands; since the sampling single chip is used for data acquisition and display control, the accuracy of the acquired data can be guaranteed; therefore, the intelligent display can be realized, the space is saved, the complexity of the data acquisition operation and computation can be reduced.

Description

technical field [0001] The invention belongs to a physical data display instrument, in particular to a circuit breaker characteristic detection integrated physical parameter display instrument and a control method used on an air circuit breaker characteristic detection platform. Background technique [0002] With the rapid and extensive application of electronic technology in the field of low-voltage electrical appliances, intelligent, high-precision, high-efficiency, and highly integrated electrical products are becoming more and more common, and have become the main electrical equipment in today's society. However, the current physical parameter display instruments of the circuit breaker characteristic detection test bench all display a single physical parameter. To realize simultaneous display of multiple parameters, multiple instruments need to be combined and used at the same time. This makes data collection more cumbersome and complicated, and at the same time causes a...
