A new warehouse of green laser pointer is under the construction

Laser processing equipment is the use of high-energy laser and high-efficiency production for people to produce the characteristics of products, equipment and life. Currently, laser processing equipment has been from the traditional model of development for the use of manual computer-controlled high-tech equipment. Laser processing equipment, work process is computer controlled and operate on their own laser processing equipment, re-run the process. Throughout the process, computer and communication technologies play a bridge between the laser device. Currently, laser processing equipment at home and abroad, often used in communication with the parallel data interface, USB interface and LAN (local area network technology) interface. A new warehouse of  green laser pointer is under the construction.
Parallel data interface referred to as "parallel." Parallel port of the "parallel" does not mean one side of the interface with the system bus data lines run parallel, but to interface with I / O device or the controlled object side of the parallel data lines. Parallel interface for short range transmission of the occasion, is an enhanced bi-directional parallel transmission interface. Parallel data interface makes the device easy to install and use, the maximum transmission speed of up to 1.5 Mbps. At present, the computer primarily as a parallel interface printer port interface uses 25-pin D-connector. 8-bit parallel data is simultaneously transmitted through the parallel lines, so that data transfer speed significantly increased, but the parallel transmission line length to be limited, because the length is increased, interference will increase, error-prone. The ventilated condition of the warehouse of    green laser pointer    can ensure the good working status of    green laser pointer    .
As a laser processing equipment, the use of parallel interface has been dominant in a given period, even in existing laser processing equipment has also been widely used. But laser processing equipment and other printer using a parallel interface, the laser-generated static pressure more, so the error rate higher; and laser processing equipment as presented in geographically dispersed and, therefore, parallel interface. " short "distance communication give large-scale use of laser processing equipment brings a great deal of restriction, which requires laser processing equipment manufacturers further developed to ensure information accuracy and more suitable for long-distance data communication interface. The drawing of    green laser pointer    has the latest revision.
USB is an abbreviation of Universal Serial Bus, the Chinese meaning "Universal Serial Bus." It is not a new bus standard, but the new field of application in the PC interface technology. As early as 1995, USB interface on the PC, successfully applied, it is the broader application of the computer interface specification. USB interface is a computer motherboard 4-pin connector, which is used between two pins to transfer data, both sides of the 2-pin power supply for the peripherals. Speed USB interface (USB2.0 up to 20 Mbps), connection is simple and requires no external power supply can be hot-swappable, while outside with good compatibility. USB interface can be as Hub (hub) as the number of expansion through the cascade, but the number can not cascade more than three, otherwise it will seriously affect the peripheral power supply voltage, so that peripherals can not work, there may burn out the motherboard ; in concrete work, USB communication line length is generally not more than 1.5m, or it may cause data loss and data transfer instability. The manager is introducing    green laser pointer    with the help of the slide.
On work with computer equipment, laser processing, USB interface is also significantly restrict the spatial extent of the laser processing equipment, the processing equipment can not be distributed in a wide range of work, seriously affect investment in large factories and mass production. Currently, some companies use a USB flash drive directly into the laser device as a carrier, can effectively solve USB communication problems of instability, after all, a good solution, but the method because they do not have bi-directional data transfer interface, communications capability, not achieve equipment, digital management, and data need to be replaced by sets of plug, which is only suitable for small businesses, small-scale production use. The package method of    usa green laser pointer   will be determined in the meeting to be held this afternoon.
