Strengthen the heat dissipation of the scanner, add the blower and the induced draft fan; in combination with the stop motor, check the contact pressure of the moving and static contacts, replace them if necessary, and replace the fatigued contact springs. Increase the research of internal temperature measurement technology of scanners, and apply new technologies such as wireless temperature measurement to solve the problem of difficult temperature measurement. This article will introduce you to the scanner driver.
In the linear power supply of the scanner, the voltage regulator circuit is a key component. Early scanner regulators were made up of discrete devices and the like. When the scanner's three-terminal integrated voltage regulator appeared, it was widely welcomed with its simple circuit and good performance. The scanner linear power supply is a regulated power supply with an early application and mature circuit. Its biggest advantage is that the circuit is simple, the performance is reliable, the number of components is small, the ripple is small, and the characteristics are good; the disadvantage is that the efficiency is low and the loss is large.
The main factor affecting the size and weight of the scanner is that the voltage regulator requires a radiator with a large enough area; the second is the use of a power frequency power transformer. The main reason for the low efficiency of the scanner is the application of a linear regulator. The scanner linear regulator regulates and regulates the voltage by adjusting the on-state voltage drop of the power regulator device.
With the rapid development of network technology, Internet technology is gradually infiltrating into the field of industrial control and intelligent scanner system design. In the future, the scanner industry will integrate technology to realize its network. The concept of network scanner is a breakthrough in traditional concepts. The network is the concept of instrument, which provides an accurate overview of the network development trend of instruments.
