Multifunctional support for electric power engineering investigation

Abstract

The invention relates to a multifunctional support for electric power engineering investigation. The support comprises a current sensor, a voltage sensor, a microprocessor, an A / D converter, an LCD liquid crystal display screen, a key panel and an instrument shell, the key panel is arranged below the LCD liquid crystal display screen, touch keys are arranged on the key panel, and measurement datadisplay and parameter setting are switched by touching the corresponding keys. According to the invention, mechanical keys are replaced by the touch keys; smooth and smooth appearance, the protrudingfeeling of the traditional mechanical key is eliminated; meanwhile, the visual perception of people is fully considered; when the key is operated through a touch action; an indicating lamp is arrangedbelow the key to indicate whether the key responds or not; a Bluetooth module and a voice module are arranged, wherein the Bluetooth module can directly transmit data in the data storage device to amobile phone or a computer, so an operator can conveniently obtain storage information in the electric power instrument; the voice module can broadcast measured data and fault places, so the reading and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a multifunctional support for electrical engineering survey. Background technique [0002] The power meter integrates the functions of power parameter measurement and power metering. It is a common component used in power systems to monitor power parameters such as voltage, current, power, and electric energy. It has the advantages of high precision, flexible display, and comprehensive functions. However, the current power The structure of the instrument is complex, the information transmission uses network signals, the cost is relatively high, and the current power meters lack the voice broadcast function, and most of the power measuring instruments basically use mechanical buttons to solve the problem of display switching and parameter setting of the meter. This solution is often not conducive to the aesthetics and waterproof design of the display panel of the po...

[0002] The power meter integrates the functions of power parameter measurement and power metering. It is a common component used in power systems to monitor power parameters such as voltage, current, power, and electric energy. It has the advantages of high precision, flexible display, and comprehensive functions. However, the current power The structure of the instrument is complex, the information transmission uses network signals, the cost is relatively high, and the current power meters lack the voice broadcast function, and most of the power measuring instruments basically use mechanical buttons to solve the problem of display switching and parameter setting of the meter. This solution is often not conducive to the aesthetics and waterproof design of the display panel of the power measuring instrument, and the mechanical keys also have problems such as insufficient sensitivity and poor durability.
