The Evolutionary History of Wireless Electricity Usage Monitor

With the invention of radio communication equipment, all kinds of wireless electricity usage monitor equipment also came into being. Radio waves are invisible and their properties are known only by instrumental measurements.

Early wireless power monitor devices were single-function instruments that required multiple instruments in order to measure multiple important parameters of radio communication equipment. Many instruments need to be placed in the measurement laboratory, and different instruments need to be connected during the measurement, which makes the measurement work not only tedious, but also affects the efficiency.

In addition, many instruments are used together, and the cables are often messy and not easy to manage. Therefore, people expect to integrate some commonly used measuring instruments into a multifunctional comprehensive instrument to improve the measurement efficiency and meet the needs of field detection. This is the origin of wireless electricity monitor.

The earliest wireless electricity usage monitor was not highly integrated, and each functional unit was relatively independent. Almost every measurement project had its own independent control panel and information display window, mainly completing the sharing and integration of power supply and partial input and output ports. It can basically meet the needs of testing, debugging and maintenance of early radio communication equipment. Because of their complex structure, high cost and large size, many of the early wireless electricity usage monitor were not integrated.

The second generation of wireless electricity usage monitor is more integrated in the control panel and user interface, making the control panel of the whole instrument have a holistic feeling. The distribution of various Settings and knobs on the control panel is more scientific, and it is no longer like the previous generation of products that a bunch of instruments are installed in a big iron box. The display part of each measurement unit is also integrated to a large extent, and the display header should adopt the form of multi-table integration as much as possible.

The third generation wireless electricity usage monitor began to introduce numerical control technology and gradually began to enhance the central control function. In the display and control interface, the number of direct display elements gradually increased, and later products began to gradually provide some simple automated test functions. With the introduction of numerical control technology, the precision and performance of the instrument have been improved, and more and more light touch switches have appeared on the operating interface.

The fourth generation of wireless electricity usage monitor starts to use single chip microcomputer and microcomputer processing chip as the control core, the wireless electricity usage monitor also entered the stage of controlled automation With the addition of microcomputer processor, the comprehensive tester has the function of data processing and automatic control.

Modern wireless electricity usage monitor keeps pace with The Times. In order to meet the increasingly complex digital communication signal measurement, the product hardware is developing toward the direction of digitalization and software-based intelligence. The high-performance processor becomes the core of the instrument, and a large number of DSP architectures replace the traditional circuits. The advantage of software-based configuration and upgrade flexibility, adding support for a new standard signal or further optimizing the measurement adding measurement template, all need to update the firmware or upload a software package.
