Embodiment Construction

[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0020] At present, most of the existing instruments on the market only have pointer display or only liquid crystal display, mainly because the motor driving the pointer in the pointer display and the A / D conversion chip in the liquid crystal display will interfere with each other, making it difficult to achieve dual display. There have also been some display instruments with pointer and digital dual display on the market, but they cannot control the position of the pointer in real time, and in the practical process, there are problems that the pointer cannot be controlled, and there are situations where the pointer exceeds the range or cannot return to zero. .

[0021] The invention is a dual-display dial indicator, which can convert the input 4-20mA electric signal into pointer scale display and li...

Abstract

The invention discloses a double-display micrometer gauge and a micrometer gauge pointer display control method. The double-display micrometer gauge comprises a sensor module, an A / D conversion chip module, a microprocessor control module, a liquid crystal display module and a pointer display module. The pointer display module comprises a pointer drive module, an angle sensor module and a pointer module. The double-display micrometer gauge can convert a 4-20 mA electrical signal output by a sensor into pointer display and liquid crystal display through an A / D conversion chip. Meanwhile, an angle sensor and the microprocessor control module and the pointer drive module form closed loop design, the position of a pointer is fed back to a microprocessor in real time through the angle sensor, and the correct indicating position of the pointer is adjusted through the pointer drive module to prevent pointer non-synchronization or pointer notoscale and the like. The double-display micrometer gauge and the micrometer gauge pointer display control method have the advantages that precise measuring and flexible operation are guaranteed due to digital display, precise display under the critical state is guaranteed through analog display, and the double-display micrometer gauge is easy to read.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to an improved dual-display dial gauge and a control method for pointer display thereof. Background technique [0002] In industrial control, most of the display information obtained by operators relies on vision, and display instruments generally refer to devices that transform the measured signals into display information that is easy for people to observe. The display instrument directly receives the output signal of the detection element and the transmitter or sensor, continuously displays and records the changes of each measured parameter during the production process. According to the different display methods, the display instrument generally indicates the detected quantities sent by sensors such as temperature, pressure, flow, material level and mechanical quantity with pointers or numbers. There are two main display forms of the instrument, one is the pointer type and...
