Digital technology (Digital Technology) refers to the use of certain kinds of information devices, including, maps, text, sound, image, etc., into computer recognizable binary numbers for computing, processing, "0" and "1", storage, transmission, distribution, reduction technology. Often referred to as digital technology. Digital technology as the basis, LSI is mainly composed of digital equipment, the analog signal is measured for A / D conversion, transmission, processing, storage and signal display are digital signal to test speed , accuracy is greatly improved, on behalf of the common instrument constant temperature and humidity box, temperature sensors. Digital is the foundation of intelligent instruments, personal equipment and virtual instrumentation, Henan high and low voltage distribution cabinet manufacturer, is the premise of computer technology into the measuring instrument. Widely used in electronic digital computer numerical control technology, communication equipment, digital instrumentation, etc., such as a human first electronic digital computer ENIAC, Zhengzhou high and low voltage power distribution, Aisida microscope, stereo microscope, X-ray machines . Note frequency control cabinet maintenance and repair of the 21st century, high and low voltage distribution cabinet prices, domestic inverter technology has been rapid development, high and low voltage power distribution equipment company in Henan, has been widely used in various industries of the national economy to promote energy saving, which greatly improves the level of China's industrial electrical transmission. But with the promotion and application of the drive, we need to pay attention to and dissatisfied outstanding issues slowly surfaced.
